2. Description of the Related Art Conventionally, composite plates used as building materials are
As shown in FIGS. 10A and 10B, a structure having a thin hard plate 1 on one or both surfaces and a soft layer 2 on the inside is often used. Some composite plates having the functions of heat insulation, heat resistance, soundproofing, sound insulation, etc. are assembled by combining different hard plates 1 and soft layers 2 at the construction site, but in recent years, in particular, standard composite plates. Therefore, many composite plates that are mass-produced at the factory are commercially available and used.

The soft layer 2 of the composite board has heat insulation, heat resistance, sound insulation,
It is an important material for maintaining functions such as sound insulation. Therefore, the soft layer 2 includes resin processed products, foamed resin products, aerated cement products, aerated gypsum products, aerated concrete products, aerated ceramic products, heat-resistant bricks, diatomaceous earth products, shirasu balloon products, glass wool products, rock wool products, While having the above functions, such as ceramic wool products, waste recycled resin products, natural wood, synthetic wood, wood piece products, wood powder products, and composite / mixed products of the above materials,
A material that is lightweight is used.

The hard plate 1 of the composite plate protects the soft layer 2 from deformation and damage, and can be attached to the base material 3 while maintaining a predetermined thickness and a predetermined shape. Has pod strength. Therefore, the hard plate 1 has A
Materials such as 1 or Al alloy, Cu or Cu alloy, iron, steel or iron alloy, stainless steel, metal such as Ti or Ti alloy, hard plastics such as vinyl chloride sheet, etc. are used. Further, the surface of the thin plate of the above-mentioned material is further subjected to a surface coating or surface treatment for the purposes of makeup pattern, appearance, texture, texture, corrosion resistance, abrasion resistance, weather resistance, bacteriostatic property, etc. Is used. Examples are a zinc-plated steel plate, a Cu or Al plate with a decorative pattern, and a satin finished plate.

The composite plate has nails, screws,
Apply a wood screw or the like (hereinafter referred to as nails or screws 18) and pierce the hard plate 1 and the soft layer 2 with a hammer or a screwdriver, especially an electric or pneumatic hammer or screwdriver in recent installation work. It is attached to the base material 3 by driving or tightening. Generally, in the case of floors and walls, decorative materials such as finishing boards, decorative boards, flooring, carpets, wallpaper, wall cloths (hereinafter collectively referred to as "overlays") are laid and used on this composite board. ing.

Particularly in the case of a floor heating composite plate, a pipe for hot water is provided inside the composite plate or along a groove on the upper surface, and the heat of the hot water is evenly distributed from the hot water pipe to the entire upper surface of the composite plate. As the hard plate 1 on the surface so as to be transmitted, a metal plate such as an aluminum plate or a Cu plate having good heat conductivity and workability is used. The composite board is attached to the base material 3 using nails, screws, etc. 18, and an overlay 19 such as a finishing board, a decorative board, and a flooring is laid on the base material 3. If the heating pipe is separate from the heat-insulating composite board, first install the heat-insulating composite board.
After being attached to the base material 3 by using nails, screws or the like 18, a heating pipe is laid on the base material 3, and a top plate 19 such as a finishing plate, a decorative plate, and a flooring is further laid thereon. In this case, of course, in order to lay the heating pipe, the heat insulating composite plate is provided with a groove or the like, so that the overlay 19 can be laid flat.

As the soft layer 2 of the floor heating composite plate, a material having a high heat insulating property such as a foamed resin is used so as to prevent heat from escaping under the floor. Also, from the viewpoint of workability, wood-based materials such as synthetic wood boards are often used.

[0008]

In the conventional mounting of the composite plate, it is surprisingly difficult to properly perform nailing and screwing, and a skilled worker is required for the construction. In recent years, the spread of do-it-yourself has increased the chances that the general public will install the composite board, but this leaves a problem in the quality of construction. That is, since it is difficult to drive nails and tighten screws properly, in the case of insufficient driving and tightening, as shown in FIG. 11A, the heads of nails and screws 18 remain protruding, and driving and excessive tightening are performed. In this case, as shown in FIG. 11B, the head of 18 such as nails and screws and the peripheral portion thereof are excessively sunk, or conversely, as shown in FIG. It had a problem of deterioration. This swelling (bulging) is likely to occur especially when the nails, screws, etc. 18 are not properly vertically driven and fallen. Furthermore, if the nails, screws, etc. 18 are not properly selected (size, helix angle, pitch), the above-mentioned troubles are likely to occur. If you use the screws and nails to install the do-it-yourself carpenter, the quality of the installation may deteriorate.

Recently, 18 nails, screws, etc. have been driven in,
Since the tightening is actually performed by an electric or pneumatic hammer or a driver, when a person other than a skilled worker works, insufficient tightening or over tightening is likely to occur, and the construction quality tends to deteriorate. Of the qualities of this construction, what is particularly important is the flatness of the upper surface of the composite board after the composite board is attached, and the function and aesthetics of the overlay that is subsequently laid on it.

[0010] The construction is not properly performed, and
If the state of B or FIG. 11C remains, even if an upper overlay 19 such as a decorative plate is attached flat as shown in FIG. 9,
Since a gap 20 is formed between the upper cover 19 and the upper cover 19, the adhesion is deteriorated, and the upper cover 19 is easily peeled off after the start of use, and deformation such as a warp 22 is likely to occur. Especially when the composite plate is a floor heating composite plate, the gap 20, the peeling 21, and the warp 22
All decrease the heat transfer from the heat transfer hard metal plate to the flooring, carpet, etc. as the overlay 19, and also cause uneven heat transfer, which not only increases the discomfort during use, but also increases the dryness. Due to the high temperature, gap 20 and peeling 2
1 and the warp 22 are further promoted, the floor becomes fluffy, the step 23 is formed at the joint portion of the flooring unit boards, and as a result, the life of the flooring is easily shortened. It was

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a composite plate having excellent workability in which floors and wall surfaces having excellent flatness can be easily obtained. .

[0012]

The composite plate of the present invention has improved workability by providing the conventional composite plate with the receiving member 4 having the dish-shaped space 9. That is, to explain in more detail including the embodiments, the composite plate of the present invention has a single-sided hard plate type having the hard plate 1 only on one side of the soft layer 2 of the composite plate as shown in FIGS. 1A and 1B. ,
There is a double-sided hard plate type having hard plates 1 on both sides.

In the case of the one-sided hard plate type, the hard plate 1 on the front side of the composite plate is, for example, an Al plate, and the soft layer 2, for example, Styrofoam may be barely exposed on the back side. It may be protected by a film. In the case of a double-sided hard plate type, the double-sided hard plates 1 may be the same material, for example, both sides may be Al plates, or different materials, for example, the front hard plate of the composite plate may be an Al plate and the back hard plate may be a hard PVC plate. In some cases.

The soft layer 2 is an important constituent material for ensuring functions such as heat insulation, heat resistance, soundproofing, and sound insulation. Materials having such functions, that is, resin processed products, foamed resin products, and lightweight. Aerated cement products, commonly known as concrete,
Aerated gypsum products, aerated concrete products, aerated ceramic products, or heat-resistant bricks, diatomaceous earth products, shirasu balloon products, glass wool products, rock wool products, ceramic wool products, waste recycled resin products, natural wood, synthetic wood, wood chip products, Wood flour products, and composites of the above materials
It is composed of materials that have the above-mentioned functions and are lightweight, such as mixed products. For example, as the foamed resin product, a foamed hard polyurethane resin or the like is preferable.

The hard plate 1 protects the above-mentioned soft layer 2 from deformation and damage, and while maintaining a predetermined thickness and a predetermined shape, only the peripheral portion of the nail is suitable for nailing or screwing. It has an important function of being able to be accurately deformed to form a seat for receiving the head of 18 such as nails and screws, and enabling it to be attached to the base material 3, so it has an appropriate plastic deformability and hardness and strength above a certain level. Composed of a material having Therefore, Al or Al alloy is often used as the material of the hard plate 1, and Cu or Cu alloy, iron, steel or iron alloy, stainless steel, T
Metals such as i or Ti alloys, hard plastics such as vinyl chloride sheets, FRP, fiber reinforced plastics, F
Materials such as RM, fiber reinforced metal, are used,
The material is not limited to these, as long as the material has hardness and strength to some extent and has the ability to be deformed along the dish-shaped portion 6 of the receiving member 4 when fixed with nails, screws, or the like 18. In some cases, any material may be used so long as a space similar to the dish-shaped space portion 9 can be formed in advance along the dish-shaped portion 6 of the receiving member 4 when the composite plate is manufactured. Further, the surface of the hard plate 1 is subjected to surface coating or surface treatment for the purposes of makeup pattern, appearance, texture, texture, corrosion resistance, abrasion resistance, weather resistance, bacteriostatic property, etc. May be. Examples are a zinc-plated steel plate, a Cu or Al plate with a decorative pattern, and a satin finished plate.

The composite plate provided with the receiving member 4 will be described with reference to FIGS. 1A and 1B. The hard plate 1 on the front side and the lower surface member 1 will be described.
5 or a plurality of receiving members 4 are provided so as to abut the hard plate 1 on the back side, and the soft layer 2 is filled between the hard plate 1 on the front side and the lower surface material 15 or the hard plate 1 on the back side. ing. Next, FIG. 1C shows an example of attachment of the composite plate of the present invention to the base material 3. In order to attach the composite plate, when nails, screws, etc. 18 are driven at the positions of the nail holes or the nail hole marks 13, only the lower part of the nail head of the hard plate 1 of the receiving member 4 is driven according to the driving of the nails and the tightening of the screws. It deforms along the dish-shaped space 9 to form a seat for the nail head. By this seat, the nail head sinks to an appropriate depth, and the tightening force is transmitted to the receiving member 4 via the hard plate 1 deformed into a dish shape. This makes the hard plate 1
The other parts are free from deformation, and the composite plate is attached and fixed to the base material 3 while maintaining the predetermined shape and thickness. In particular, since the surface of the composite plate is prevented from rising due to insufficient driving or insufficient tightening of nails or screws 18 and the flatness is ensured, the overlay 19 can be appropriately and easily applied.

FIG. 1D shows an example of mounting when the height h of the receiving member 4 is shorter than the thickness T of the soft layer 2. in this case,
Spacers 17 as shown in FIG. 7D may be arranged in the soft layer 2. The basic structure of the receiving member 4 is, as shown in FIG. 2A, an abutting portion 5 that abuts the hard plate 1, a dish-shaped space portion 9 adjacent to the hard plate 1, and a through hole 10 that guides nails, screws, and the like 18. It is a structure with. The receiving member 4 of FIG. 2A
In a typical embodiment, is a flat flange-shaped contact portion 5, a dish-shaped portion 6 that forms a dish-shaped space portion 9 inside, and a through hole 1.
And a shaft cylinder portion 7 having 0. The conduction hole 10 is formed as a through hole as shown in FIG. 2A, and as in the case of FIG. 2B.
In some cases, it is a blind hole having a sealing portion 8 at the lower end.

2A and 2B, the contact portion 5 of the receiving member 4 is basically flat plate-shaped or flat flange-shaped, contacts the hard plate 1, and is flat on the hard plate 1. Receives pressure from the part (non-deformed part). When fixing the composite plate with nails, screws, etc. 1, use nails, screws, etc. 1
The driving force and the tightening force of 8 are received by this surface together with the dish portion 6.

The size of the contact flat surface of the contact portion 5 is appropriately changed depending on the softness of the soft layer 2 and the strength of the hard plate 1. When the soft layer 2 is a foamed resin and the hard plate 1 is an Al plate, it is made large, and when the soft layer 2 is lightweight concrete, and the hard plate 1 is an Al plate, it is made small. In some cases, the abutting flat surface portion may be omitted as shown in FIG. 8, and only the thick portion of the dish-shaped portion 6 may abut.

The cross-sectional shape of the abutting portion 5 perpendicular to the axis of the receiving member 4, that is, the KK 'cross-sectional shape of FIG. 2A, may be a circular shape that is easy to manufacture for both the inner and outer circumferences. , Rotation prevention, support of hard plate 1, designability,
The shape may be a square shape, a rectangular shape, a hexagonal shape, or various shapes as shown in FIGS. 4 and 5 in consideration of mold convenience and the like.

As shown in FIG. 2A, the dish-shaped portion 6 of the receiving member 4 has a dish-shaped space portion 9 formed therein, and has a dish-shaped longitudinal section, and the abutting portion 5 of the receiving member 4 and the shaft tubular portion 7 are formed. Located in the middle of. When nails, screws or the like 18 are driven in or tightened, the hard plate 1 deforms and sinks along the dish-shaped space 9 inside the dish-shaped portion 6 and is received by the inner surface of the dish-shaped portion 6. The dish-shaped space portion 9 is a space portion adjacent to the hard plate 1 and has a shape and a size corresponding to the head of the nail or screw 18 to be used, and when the nail or screw 18 is driven or tightened, Due to the deformation and sinking of the hard plate 1, nails, screws, etc. 1
Form a seat for eight heads. When nails, screws, etc. 18 are driven in or tightened, the tightening force is received by this dish-shaped portion 6 via the deformed hard plate 1 (deformation part), and the tops of the nails, screws 18, etc. 18 are of the composite plate. Stops where it coincides with the top surface. Therefore, the depth of driving and tightening of the nails, screws, etc. 18 becomes appropriate and even by the receiving of the dish-shaped portion 6. At the same time, the hard plate 1 is also deformed in the dish-shaped space portion 9 at a necessary portion as much as necessary to prevent the peripheral portion from being swollen as in the conventional example.

In this way, when the nails or screws 18 are driven in or tightened, the dish-shaped portion 6 is used to prevent insufficient driving or over-tightening, thus causing the problems shown in FIGS. 11A, 11B and 11C. To be prevented. In addition,
The shapes of the dish-shaped space portion 9 and the dish-shaped portion 6 are as shown in FIGS.
It is not limited to the funnel type with an inclined surface like
Depending on the head shape of the nails, screws, etc. used, there are some with a flat neck bottom as shown in FIG. 3B, some with a step, and some with a combination with an inclined surface.

The cross-sectional shape of the dish-shaped portion 6 perpendicular to the axis of the receiving member 4, that is, the LL 'cross-sectional shape of FIG. Similar to the outer circumference of the contact portion 5, a square shape for the purpose of preventing rotation,
It may have a rectangular shape, a hexagonal shape, or various shapes as shown in FIGS. 4 and 5. Since the inner peripheral cross-section receives the lower neck of the head of 18 such as nails and screws, it corresponds to the case where this neck is polygonal, but it is generally circular and the inner periphery of the shaft tube portion 7 is When the cross-sectional shape is as shown in FIG. 5, it may be an extended shape.

As shown in FIG. 1, FIG. 2 and FIG. 3, most of the axial tube portion 7 of the receiving member 4 has a tubular shape in the axial direction,
It has a through hole 10 inside. The through hole 10 guides the nails, screws, etc. 18 easily when the nails, screws, etc. 18 are driven in and tightened, and the nails, screws, etc. 18 after the driving, are tightened.
Hold. Further, the shaft tube portion 7 extends in the thickness direction of the composite plate, supplements the strength in the thickness direction of the composite plate, and receives the driving force of nails 18 such as nails and screws applied to the dish-shaped portion 6 and the contact portion 5.

The through hole 10 of the shaft cylinder portion 7 is of a through hole shape as shown in FIG. 2A or a blind hole shape having a sealing hole portion 8 at the lower end of the shaft cylinder portion 7 as shown in FIG. 2B. . In general, the through hole 10 is often used as a through hole, but the receiving member 4
When the height h of the soft layer is smaller than the thickness T of the soft layer 2, the receiving member 4 having the sealing portion 8 is used to prevent the soft layer raw material from flowing into the through hole 10 during the production of the composite plate. It

The cross-sectional shape of the shaft tube portion 7 perpendicular to the axis of the receiving member 4, that is, the MM 'cross-sectional shape of FIG. Square shape, hexagonal shape or Figure 4
Alternatively, it may have various shapes as shown in FIG. The inner peripheral cross-sectional shape is preferably the same as the outer diameter of the nails / screws 18 to be used or slightly smaller in diameter, but the nails / screws 18 can be easily penetrated while tapping. Makes it easy and nails after driving and tightening.
In order to increase the holding power of the screws 18 etc.,
While having an inner diameter slightly smaller than the outer diameter, the serrated shape or the inner toothed shape as shown in FIG. 5 may be used.

FIG. 4A shows a circular shape in both the outer peripheral shape and the inner peripheral shape. FIG. 4B shows that the outer peripheral shape is rectangular or square, and the inner peripheral shape is circular. FIG. 4C shows that the outer peripheral shape is petal-shaped and the inner peripheral shape is circular. FIG. 4D shows that the outer peripheral portion has a chamfered rectangular shape or a square shape, and the inner peripheral portion has a circular shape.

FIG. 4E shows that the outer peripheral shape is oval and the inner peripheral shape is circular. FIG. 4F shows that the outer peripheral shape is a gear shape and the inner peripheral shape is a circular shape. FIG. 4G shows that the outer peripheral portion has a serration shape and the inner peripheral portion has a circular shape. FIG. 4H shows that the outer peripheral portion has a circular shape partially having a protrusion and the inner peripheral portion has a circular shape. Although it is possible to provide a plurality of protrusions, the outer peripheral shape may be a petal shape as shown in FIG.
It is different from the gear shape like F.

In addition to these, although not shown, as non-circular anti-rotation variants, diamond shapes, polygonal shapes, spline shapes, Mitsubishi shapes, Aoi shapes, multi-leaf shapes, trademark mark shapes, character shapes, etc. Can have many shapes. The structures of the KK 'cross section of the contact portion 5, the LL' cross section of the dish-shaped portion 6, and the MM 'cross section of the shaft tubular portion 7 are generally shown in both the outer peripheral shape and the inner peripheral shape. 4A, a circular shape may be used, but when the strength of the soft layer 2 is low, it is desired that the outer peripheral shape is a non-rotating shape, and at least one of the contact portion 5, the dish-shaped portion 6 and the shaft tubular portion 7 is formed. In place, it is preferably a detent variant of the shape shown in and not limited to FIGS. 4B-4H.

For example, when the soft layer 2 has a high strength such as lightweight concrete, the outer peripheral shape may be circular, but in the case of a soft foamed resin, it has a non-circular shape and a non-rotating shape. It is preferable to have one. The reason why the non-rotational variant is preferable is that when tightening a screw or the like, the rotating force of the tapping action of the screw acts to rotate the receiving member 4, and when the receiving member 4 rotates, the screw stops moving. It is because it will not be possible to tighten it.

The inner peripheral shape of these cross-sectional structures may be basically circular as described above, but M-
The inner peripheral shape of the M'section is an internal gear shape, a spline shape,
In the case of serrations, etc., fixing with nails, screws, etc. 18 having a diameter between the minimum inner diameter and the maximum inner diameter allows the nails, screws, etc. 18 to be easily driven and tightened, and The receiving member 4 is firmly fixed, and thus the composite plate is surely fixed. FIG. 5 shows a part of an example in which the inner peripheral shape of the MM ′ cross section of the shaft tubular portion 7 applies to these and the outer peripheral shape thereof is non-circular.

Of course, KK 'cross section, LL' cross section, M-
Any of the M ′ cross sections is not limited to the illustrated examples of FIGS. 4 and 5. The height h of the receiving member 4 is basically equal to the thickness T of the soft layer 2 of the composite plate, but it is not necessarily required to be equal to T when the strength of the soft layer 2 is sufficient. , H <T, there is no problem. When h <T, the receiving member 4 having the above-mentioned sealing portion 8 is preferably used.

The material of the receiving member 4 is resin, recycled resin, hard rubber, or metal having a hardness capable of tapping by nailing or screws, such as Al, Al alloy, Z.
n, Zn alloy, Cu, Cu alloy, lead, lead alloy, and various steel materials are used. When tapping of the inner diameter portion is not performed, a ceramic material is used in addition to the above. As the type of resin, ABS resin or the like is preferable.

Since the receiving member 4 is an important member that receives the driving force of nails 18 such as nails and screws and firmly attaches the composite plate to the base material 3, a material having sufficient strength to endure it is used. In this case, the resin has an appropriate elasticity, and the soft Al alloy, the lead alloy, etc. have an appropriate plastic deformability, so that the mounting of the composite plate becomes a strong and soft structure, and the earthquake resistance of the building is also improved. preferable. In particular, the soft layer 2 is so-called lightweight concrete, such as aerated cement products, aerated gypsum products, aerated concrete products,
If it is either a cellular ceramic product or a heat resistant brick, a diatomaceous earth product, a shirasu balloon product or a hard wood-based product, the receiving member 4
Material has a smaller elastic modulus and a larger elastic limit than the material of the soft layer 2,
Alternatively, if it has a high plastic deformation property, even if the seismic intensity of the earthquake is large, the mounting of the receiving member 4 is maintained and the soft layer 2
Since it prevents the destruction of, it is possible to obtain a composite board with excellent earthquake resistance. For example, materials having a low elastic modulus and a large elastic limit include resins and hard rubber having a high elasticity, and examples of materials having a high plastic deformability include lead alloys, zinc alloys and mild steels.

Although the receiving member 4 has a complicated shape, it needs to be mass-produced at low cost, and resin and recycled resin are most preferable because they can be injection-molded. In the case of metal, it is manufactured by casting or a manufacturing method of expanding or contracting one end of a cut tube. In the composite plate of the present invention, the receiving member 4 and the nail hole or the nail hole mark 13 of the hard plate 1 are formed at the center thereof.
It is arranged together with.

The nail holes, which are also called screw holes when using wood screws, are holes for driving the nails, screws, etc. 18, and the arrangement thereof is an array in consideration of the connection with the base material 3 and arranged in rows. , Staggered and arranged in various patterns. Further, the nail hole mark is merely a mark and no hole is formed, but the marks are written on both front and back surfaces of the same hard plate 1, and the front surface mark and the back surface mark have their centers aligned.

When the receiving member 4 having the sealing portion 8 is used, the back surface mark is a mark accompanied by a concentric circle, a scaled XY axis, etc., and enables positioning of the receiving member 4. . In the first invention of the present application, in a composite plate having a thin hard plate 1 on one or both surfaces and a soft layer 2 inside thereof, an abutting portion 5 with the hard plate 1 and a dish shape adjacent to the hard plate 1 A plurality of receiving members 4 having a space 9 and a through hole 10 for guiding nails, screws 18, etc.
Is provided inside the hard plate 1 with its center aligned with the nail hole or the nail hole mark 13 of the hard plate 1.

This is a method in which the needle-shaped portion of the centering jig is pierced upward from the lower side of the hard plate 1 in FIG. The receiving member 4 is positioned such that the conducting hole 10 is fitted into the protruding jig needle portion, and the needle jig is then removed downward. Even when the receiving member 4 has the blind through hole 10 with the sealing portion 8, this method can be used without any trouble.

When the blind conduction hole 10 with the sealing portion 8 is provided, centering can also be performed by a nail hole mark without using the needle jig. The nail hole marks are positioned by the back surface mark 14 of the hard plate 1 because the centers of the marks are aligned on the front and back of the hard plate 1. In this case, when the receiving member 4 is placed, the nail hole cannot be seen, so that the back surface mark 14 is a concentric circle or a scale XY.
It is a mark on which the axis is written, and is positioned by the outer circumference of the contact portion 5 of the receiving member 4.

When the height h of the receiving member 4 is smaller than the thickness T of the soft layer 2, as shown in FIG. 7D, the receiving member 4 is placed on the back mark 14 on the front hard plate 1 by the above procedure. After arranging and adhering and temporarily fixing, the shaft cylinder portion 7 of the receiving member 4
Is closed with paper or the like (preferably, if the receiving member 4 having the sealing portion 8 at the end is used, the work of closing the end with paper or the like is unnecessary), the spacer 17 and the like are attached to the hard plate 1. The lower surface member 15 (which may be the hard plate 1 on the back side of the composite plate) is placed and fixed on the upper surface at an appropriate interval, and the hard plate 1 on the front side, the lower surface material 15 on the back side, and the receiving member 4 are fixed. The soft material raw material for forming the soft layer 2 is flow-injected into the void 16 constituted by
When solidified, the composite plate is completed in the same manner as the above method. As described above, the manufacturing method of attaching the lower surface material 15 so as to cover the lower surface material later may be adopted.

The tenth invention is characterized in that, in the ninth invention, when the receiving member 4 is arranged, the receiving member 4 is temporarily fixed to the hard plate 1. The temporary fixing method has been described above by using the double-sided tape or the adhesive on the abutting portion 5, but the method is not limited to this, and the receiving member 4 can be easily temporarily fixed at the time of centering. Anything may be used, such as a step or a minute protrusion on the back surface of the hard plate 1 that receives the outer circumference of the contact portion 5, a minute positioning unevenness provided on the contact portion 5 corresponding to the unevenness of the back surface of the hard plate 1, or centering. Alternatively, a soft center rod that does not hinder nailing or tightening may be used.

The purpose of temporary fixing is to prevent the center of the receiving member 4 from deviating from the center of the nail hole or the nail hole mark 13 of the hard plate 1. A fixing method without play is acceptable, but the soft layer 2 If it is soft like foamed resin, temporarily fix the receiving member 4 to allow some play so that even if the center is slightly displaced, the centers will be perfectly aligned when nailing and screwing. It is preferable because fine adjustment of familiarity is performed. As a method of temporarily fixing the receiving member 4 that allows such a slight play, there is a method using a double-sided tape.

The eleventh aspect of the present invention relates to a receiving member 4 for mounting a composite plate, which is installed in a soft layer 2 of a composite plate having a thin hard plate 1 on one or both surfaces and a soft layer 2 inside the hard plate 1. 1, a contact portion 5 that abuts the hard plate 1, a dish-shaped space portion 9 that is adjacent to the hard plate 1, and a conduction hole 1 that guides nails, screws, etc.

The basic structure is the one shown in FIG. 2A without the structure and the one shown in FIG. 2B with the sealing portion 8.

Regarding the longitudinal section along the axis of the receiving member 4, various embodiments are shown in FIGS. 2 and 3. In any case, the contact portion 5, the dish-shaped portion 6, the dish-shaped space portion 9 and the conduction hole 10 are present. FIG. 2A is a typical embodiment of the receiving member 4, the dish-shaped space 9 is frustoconical, and the through hole 1 is formed.
0 is a through-hole type.

FIG. 2B is a typical embodiment together with FIG. 2A, which has a sealing portion 8 at the end of the shaft tube portion 7 and a through hole 10.
Is a blind hole type. FIG. 3A shows that there are various design embodiments based on the strength and manufacturability of the receiving member 4. FIG. 3B shows a case where the inner surface of the dish-shaped portion 6 of the receiving member 4 is composed of a vertical cylindrical surface and a horizontal annular surface, and the dish-shaped space portion 9 has a disc shape. When using a nail, screw or the like having a horizontal bottom of the head of the head of 18 or the like, the dish-shaped space portion 9 or the dish-shaped portion 6 is formed with a seat corresponding to the shape of the head of the nail or screw 18 to be used. It is designed so that it shows an example of an embodiment in that case.

FIG. 3C has a flat contact portion 5 and a dish-shaped portion 6 on the front surface side of the composite plate, and the flat contact portion on the other end of the shaft cylinder portion 7, that is, on the back surface side of the composite plate. The case of having 5 is shown. Such a receiving member 4 is used when the soft layer 2 is soft, increases the strength of the composite plate itself and the attachment strength of the composite plate to the base material 3, and allows the base material 3 to be attached without deforming the composite plate. Allows stable installation of.

FIG. 3D shows a case where the cylindrical portion 7 and the flat abutment portion 5 are provided at both ends of the shaft tubular portion 7. In this case, the receiving member 4 not only has the same effect as the example of FIG. 3C,
Since the front and back sides of the composite plate are symmetrical and can be used regardless of which side is the front side, usability in construction is improved. Figure 3E
3A, FIG. 3B, FIG. 3C, and FIG. 3D show that there may be a sealing portion 8 respectively.

When the soft layer 2 is light and soft like foamed resin, the receiving member 4 withstands the driving force and the tightening force of the nails and screws 18 and receives the load. It is preferable that the structural strength of is higher than that of the soft layer 2 of the composite plate. A twelfth invention relates to the receiving member 4 in the eleventh invention, wherein the outer peripheral shape of the cross section perpendicular to the axis of the through hole 10 of the receiving member 4 is a non-circular shape at any position of the receiving member 4. A thirteenth aspect of the present invention, which is characterized in that it has a stop shape, relates to the receiving member 4 of the eleventh or twelfth aspect, characterized in that the conduction hole 10 has a sealing portion 8.

The fourteenth invention relates to a method for attaching a composite board, wherein a composite board having a thin hard board 1 on one or both surfaces and a soft layer 2 on the inside is used as a floor board using nails, screws, etc. In a method of attaching to a base material 3 such as joists, pillars, etc., a plurality of abutting portions 5 with the hard plate 1, a dish-shaped space portion 9 adjacent to the hard plate 1, and a through hole 10 for guiding nails, screws 18, etc. It is characterized in that the individual receiving members 4 are used to receive the tightening force by the nails and screws 18 and the deformation of the hard plate 1 by the receiving members 4 or by the receiving members 4 and the soft layer 2.

Nails, screws, etc. for attaching the composite board 1
8 includes a nail, a screw, a wood screw, a screw, a bolt and the like, but is not limited to this, and has a straight shaft portion and a head portion connected thereto, and this head portion deforms the hard plate 1. Any locking member that fits in the dish-shaped portion 6 and whose top portion does not project outside the outer surface of the hard plate 1 may be used. The shape of the head of 18 such as nails and screws may be such that the bottom of the neck is tapered or flat.

For mounting the composite plate of the present invention, the composite plate is arranged at a predetermined position of the base material 3, and the nail hole or the nail hole mark 13 is formed.
Apply nails, screws, etc. 18 to the center of the, and drive or tighten using an electric, pneumatic or manual hammer or drill. At this time, the nails, screws, etc. 18 are deformed along the dish-shaped portion 6 of the receiving member 4 around the nail hole or the nail hole mark 13 of the hard plate 1, but in the portion other than the dish-shaped portion 6, the receiving member 4 is formed. As a result, the hard plate 1 is prevented from being deformed, so that a highly flat mounting state can be obtained in which abnormal deformation of the hard plate 1 does not occur at the peripheral portion where the nails, screws, etc. 18 are mounted.

The means detailed above are also used for a composite plate for floor heating.

[0061]

In the composite plate constructed as described above, the receiving member 4 supports the hard plate 1 constituting the composite plate from the inside, so that the composite plate keeps a constant thickness and, by extension, the upper surface of the composite plate. Has the role of keeping it smooth. Further, the receiving member 4 functions as a guide for the nails, screws and the like 18 and can smoothly position the nails, screws and the like 18 at a predetermined position, thus preventing deformation of the peripheral portion of the hard plate 1 in the nail hole. Has a role of keeping the upper surface of the composite plate smooth.

Further, when the composite plate is attached with the nails, screws, etc. 18, the receiving member 4 receives the load, so that the hard plate 1 is not deformed except the portion pressed by the nails, screws, etc. 18, and At the portion pressed by the nails / screws 18 or the like, the hard plate 1 is received by the dish-shaped seat surface under the head neck of the nails / screws 18 while conforming to the dish-shaped portion 6 of the member 4 to press the hard plate. Since 1 is deformed along the dish-shaped portion 6, it is possible to prevent abnormal deformation of the peripheral portion of the hard plate 1 in the nail hole and to keep the upper surface of the composite plate smooth.

Furthermore, if the nails, screws, etc. 18 are properly selected, the heads of the nails, screws 18, etc. will not protrude outside the upper surface of the composite plate. The shape of the cross section of the receiving member 4 perpendicular to the axis of the through hole 10 is generally circular and sufficiently functions. When the nails, screws, etc. 18 have a threaded portion, a rotational force acts when attaching or tightening them, so in order to prevent the rotation of the receiving member 4, the shape of the outer peripheral portion of the cross section of any part of the receiving member 4 is changed. A non-circular non-rotating variant is used to prevent rotation due to the resistance of the soft layer 2.

Since metal is generally ductile, the hard plate 1 can be easily deformed along the dish 6 by using the hard plate 1 as a metal. Further, when the hard plate 1 is a thin metal plate, even when there is no nail hole and only the nail hole mark, the hard plate 1 can be easily fixed by penetrating with the nails, screws or the like 18. Since the soft layer 2 has the functions of heat insulation, heat resistance, soundproofing, sound insulation, etc., a resin processed product, a lightweight concrete product or the like, which is foamed to reduce the weight, is used depending on the application.

The abutting portion 5 of the receiving member 4 works integrally with the dish-shaped portion 6 to prevent the hard plate 1 from deforming undesirably in portions other than the dish-shaped space 9. In the manufacture of the composite plate, the nail hole and the axial center of the receiving member 4 are aligned with the back surface of the hard plate 1 having a plurality of nail holes or nail hole marks 13 (marked on the front and back with their centers aligned). The receiving member 4 is placed and positioned so that the lower surface member 15 (which may be the other hard plate 1) is placed, or the height of the receiving member 4 is greater than the required thickness of the soft layer 2. If the size is small, the lower surface material 15 (which may be the other hard plate 1 in some cases) is placed on the spacer 17, and then the soft material is used as the hard plate 1, the lower surface material 15, and the receiving member 4. The composite plate is integrally molded and manufactured by flow-injecting into the voids 16 formed in 1 and solidifying. In the case where the weight reduction is performed by foaming, as described above, the fluidized material which has been foamed may be injected in some cases, and the foaming treatment step such as heating after injecting a small amount of two liquids may be performed. Also, the attachment of the lower surface material 15 may be performed after the soft material raw material is filled around the receiving member 4 as described above.

When manufacturing this composite plate, the receiving member 4
Is temporarily fixed after being positioned on the back surface of the hard plate 1, it is possible to prevent the receiving member 4 from moving or tilting during the filling of the soft material raw material, which is more effective. In addition, the temporary fixing method using a method such as double-sided tape that allows a slight amount of play allows the soft material to be foamed resin even if the accuracy of positioning the receiving member 4 and driving or fastening 18 such as nails or screws is slightly lowered. When it is soft as described above, the adjustment is automatically performed, which is preferable.

The sealing portion 8 of the shaft tube portion 7 of the receiving member 4 has the function of preventing the soft material raw material from flowing into the through hole 10 at the time of manufacturing the composite plate, and has a function of preventing the soft material raw material from flowing into the through hole 10. In addition, it has the effect of slightly contributing to the increase in the fixing strength. Further, when the soft layer 2 is soft, the strength of the receiving member 4 is higher than that of the soft layer 2, so that the load at the time of mounting is taken up by the receiving member 4, so that the soft layer 2 is not deformed and therefore the composite plate Can be maintained in a fixed form.

On the contrary, when the soft layer 2 has a considerable hardness or brittleness, such as foam cement, foam conlite, and foam ceramics, the receiving member 4 has a resin having a small elastic modulus and a large elastic limit, or the like. If an alloy having a high plastic deformation property is used, the receiving member 4 absorbs vibrations caused by an earthquake or traffic, and a highly safe structure having a soft structure can be obtained.

[0076]

According to the invention described in detail above, a composite plate having remarkably excellent workability was obtained. Firstly, the workability in attaching the composite plate to the base material was remarkably improved, and secondly, the quality after attachment was remarkably improved. The first improvement in workability is that the hard plate can be properly deformed only in the dish-shaped space when it is attached with nails, screws, etc. by the dish-shaped space provided at the bottom of the nail hole of the hard plate. hand,
Other parts of the hard plate, that is, the flat part does not swell or deform,
Moreover, since the nails and screws can be received by the dish-shaped part,
The nails and screws will not be over-tightened or overtightened, and the nails and screws will be tightened to the proper depth and then stopped.
The heads of nails, screws, etc. do not project or are recessed too much, so even if an amateur does the work without requiring a skilled worker, and even if an electric / pneumatic tool whose tightening is difficult to control is used, quick and accurate operation is possible. It is possible to do various tasks.

The second quality improvement is that the deformation and swelling of the flat surface of the hard plate is eliminated and the sinking of the heads of nails, screws, etc. becomes constant, and the protrusion of the heads of nails, screws, etc. This is because the flatness of the upper surface of the composite plate after attachment of the composite plate was remarkably improved because there was no excessive depression. Therefore, when an overlay such as a flooring, a carpet, or a wallpaper is applied on this, the appearance of these finished surfaces is remarkably improved. Particularly, when the composite board is a composite board for heating, the adhesion between the overlay and the composite board such as flooring is remarkably improved, so that even if the heat transfer is used for a long period of time, the floor as shown in FIG. May become fluffy, the flooring may warp, a step may occur at the seam between plates, uneven heat transfer may occur, and as a result the life of the flooring may be shortened. There is no.

Furthermore, if a material having appropriate elasticity or plastic deformability is selected as the material of the receiving member, the composite plate can be attached to the base material with a soft structure to absorb vibrations, so that the composite plate can be absorbed even in the event of a large earthquake. It is possible to obtain a structure with excellent seismic resistance that does not cause damage to the base material or separation and separation from the base material.
