Description

[Detailed description of the invention] This invention is made by bending a flat plate or an embossed metal thin plate, and providing a main body with a cross-section shape and guide and locking protrusions formed on both side wall ends of the main body. A surface material consisting of a male type connection part with an insertion edge and a female type connection part with a protrusion formed at the tip, a synthetic resin foam filled in the back surface of the surface material, and a back surface material covering the back surface are integrated. In addition to strengthening the engagement force and waterproofness, it is also easy to drive nails during construction, and the synthetic resin foam is reliably formed in the gap formed between the front and back materials to provide heat and sound insulation. The present invention relates to a siding board (hereinafter simply referred to as a board) that also has functionality.

Conventional boards have a structure that provides properties such as heat insulation, waterproofness, and strength. However, in the structure of this type of board, almost no treatment has been taken to suppress the deterioration of the performance of the board itself, and the back side material may be damaged due to peeling between constituent materials, water intrusion from joints or edges, etc. This often caused swelling, rash, corrosion, etc. of the core material. In addition, because the side end surface of the backing material, the so-called untreated texture surface, is directly interposed between the connecting parts of the boards and exposed, moisture can easily impregnate or accumulate, causing corrosion or deformation of the connecting part constituent materials. Therefore, durability decreases,
Moreover, the structure of the connecting portion does not allow elasticity to effectively act on the engaging portion, resulting in drawbacks such as the boards coming apart from each other. Furthermore, when driving the board onto the trunk rim, the nails are driven with a hammer onto the surface of the extension of the female joint, so they are bounced off by the elasticity of the synthetic resin foam, making installation extremely difficult. Hammer damage was often caused to the surface, and the supporting force of the nails was merely to fix the surface material.

In order to eliminate such drawbacks, the present invention sandwiches and covers both side edges of the backing material with the fronting material, and
By filling the space between the front and back materials with synthetic resin foam raw materials, these components are bonded together, and the ends of the male and female joints are in a protruding state to strengthen engagement force and waterproofness. The present invention proposes a board in which the protruding part also serves as a guide when connecting the boards, making it easier to install, and also having excellent corrosion resistance and productivity.

An embodiment of the board according to the present invention will be described in detail below with reference to the drawings. That is, Fig. 1 is a perspective view showing a typical example of the above-mentioned board, where 1 is the surface material and the longitudinal section is shown in Fig. 2.
The main body part 2 is shaped like a main body part 2, the insertion edge 4 extends outward from the lower edge of the side wall 3 of the main body part 2, and the tip of the insertion edge 4 is bent inward in the shape of an upward seam, and also serves as a guide and engages in an upwardly protruding manner. A male connecting part 6 formed from a locking protrusion 5 (hereinafter simply referred to as a protrusion), an insertion groove 8 whose lower end edge of the other side wall 7 is bent inward in a U-shape, and its lower edge 9 are outwardly The extension part 10 extends upward, its tip protrudes upward, a protrusion 11 is formed parallel to the side wall 7, a reinforcing side wall 12 extends the lower end of the protrusion 11 downward, and its lower edge extends inward. It is composed of a bent portion 13 and a male connecting portion 14 formed from the bent portion 13. To explain further, the main body part 2 consists of a rectangular decorative surface 2a, side walls 3, 7, and a concave part 2b, and the protrusion 5 projects upward at an angle θ, mainly to strengthen the engagement force by elasticity. It has a primary waterproof function. Its height h ₁ is the height of the insertion groove 8 h ₂
It is preferable that the obtuse angle is smaller and the angle θ is easier to insert as shown in the figure. In addition, the protrusion 11 has an extension portion 10
In addition to functioning as a sturdy end side surface, it is also useful for waterproofing and strengthening the engagement force. Note that the height h ₃ only needs to protrude from the surface of the extension portion 10, but is preferably about 2 to 5 mm.
The surface material 1 is galvanized iron plate, colored steel plate, stainless steel plate, copper plate, aluminum plate, Gulfuan, etc.
A flat plate or an embossed plate of galvalume steel plate is continuously formed by, for example, extrusion or roll forming. Reference numeral 15 denotes a back surface material, which is formed in a vertical cross section as shown in FIG. 3 and faces the back surface of the surface material 1 through a synthetic resin foam 20, which will be described later. In other words, the back material 15 has a horizontal protrusion 16
, a side surface portion 17 whose inner end is bent downward, and a horizontal extension portion 18 whose lower end edge is extended horizontally toward the reinforcing side wall 12, and if necessary, the tip of the horizontal extension portion 18 may be bent outward. It is constructed from an inclined and protruding rising portion 19. To explain further, the backing material 15 mainly serves as a cover material, a reinforcing material, a sealing material, a waterproofing material, a shape material, and a shape-retaining material, and its material may be a sheet material with shape-retaining properties, such as a plastic sheet, Metal sheets (including foils of A, Fe, and Pb), paper sheets (asphalt felt, kraft paper, etc.), nonwoven fabrics,
and a composite material made by laminating, vapor depositing, etc. one or more of the above materials. In addition, the tip of the protrusion 16 of the back material 15 is held between the protrusions 5, and the side end portion of the horizontal extension 18 is placed between the bent portion 13 and the extension 10, or the tip of the rising portion 19 is placed between the protrusion 11. It is disposed so as to be in contact with the back surface of the board, so that both side edges of the back surface material 15 are not exposed at all on the board, making it possible to prevent water from impregnating. Reference numeral 20 is a synthetic resin foam (hereinafter simply referred to as foam), and is composed of an upper layer 20a, a lower layer 20b, an adhesive layer 20c, and an adhesive/spacer layer 20d, as indicated by hatching for convenience. That is, the upper layer 20a is the foam 20 filled in the recessed part 2b, and the lower layer 20b is formed from the back surface of the recessed part 2b excluding only the range of Δ near the side wall 3, the lower edge 9, and the extended part 10 downward. Forms 20 and 20c existing in the protruding portion are thinly filled in the space surrounded by the back surface of the insertion edge 4 and the back material 15. Forms 20 and 20d are present in the reinforcing side wall 12 and the bent portion 1.
3 and the surface of the rising portion 19 of the back material 15 is filled with the foam 20. This foam 20 may be made into a single body or a composite body depending on the forming method, but preferably, these constituent materials are adhered together by self-adhesion during foaming by discharging liquid raw materials. is desirable.
Note that the above Δ is the insertion edge 4 as shown in FIG.
When connected to the insertion groove 8, it is determined by the relative relationship between the dimensions, strength, and heat insulation properties of each part of the connecting part. That is, Δ is a part of the lower layer 20b that is depressed due to the connection structure. Further, the form 20 to be explained mainly under normal use conditions, ○A insulation material, ○B waterproof material and moisture proof material, ○C sound absorbing material, ○niction material, ○H vibration isolation, cushioning material, ○H bulk. It functions as a top material and an adhesive. Of course, when manufacturing the foam 20, it is desirable to use a raw material that has fluidity and self-adhesiveness and can be molded all at once without being influenced by the shape. This form 20
Specific examples include polyurethane foam, polyisocyanurate foam (including phenol and urethane modified), phenol foam, and mineral fibers (glass fibers, asbestos fibers, rock wool), carbon fibers, metal fibers, and pearlite particles in these foams. , Shirasu balloons, vermiculite, foams containing glass beads, etc. The blending ratio of this type of additive varies depending on the purpose, but for example, for 100 parts by weight of foam raw material,
It is about 5 to 200 parts by weight.

Next, a construction example will be explained.

First, as shown in FIG.
The female connecting portion 14 of the board α is fixed onto the board 1 with nails 22. Next, insert the insertion edge 4 of the male connecting portion 6 of the board β into the insertion groove 8 of the board α as shown in FIG. 5, and insert the female connecting portion 14 (not shown) at the other end. It is fixed with nails 22. In addition, when inserting the insertion edge 4 of the board β into the insertion groove 8, even if the board β is tilted as shown in FIG. 5, the protrusion 5 slides on the extension part 10 as a guide, making the installation easy. It can be performed. In addition, as shown in FIG. 4, the connected state of the boards α and β is improved by the synergistic effect of the pushing up of the board β by the protrusion 11 and the pressing of the protrusion 5 in the insertion groove 8. In addition, a gap is reliably formed between the insertion groove 8 and the insertion edge 4, and capillary phenomenon can be prevented, resulting in improved waterproofness. Moreover, since the side end surfaces of the back material 15 are held between the protrusions 5, they are not exposed inside the connecting portion.
It is possible to form a connected structure without moisture impregnation or moisture retention within the connecting portion. Further, when driving the nail 22, due to the back-up by the reinforcing side wall 12 and the bent portion 13, and the reinforcement by the protrusion 11, the nail 22 does not bounce back and deformation of the female connecting portion 14 can be prevented.

What has been described above is only one embodiment of the board according to the present invention, and the surface material 1 can also be formed as shown in FIGS. 6a to 6r. That is, Fig. a shows a spring in which the lower end of the side wall 3 is bent inward, then protrudes outward to provide a reinforcing rib 3a, and the tip of the bent portion 13 is bent inward to form a flap.

The surface material 1 has a slanted surface, the q figure shows the surface material 1 in which the protrusions 11 are formed into ripple-like ribs, and the r figure shows the bent part 13.
This is the surface material 1 that extends outward. Moreover, FIGS. 7a-7q show other embodiments of the back material 15.
That is, figures a and b show the back surface material 15 with the protrusion 16 inclined at an angle of θ, and figure c shows the side surface part 17 and the horizontal extension part 1.
The back surface material 15 has a curved corner where 8 intersects, and the back surface material 15 in which the projections 16 are formed in a ripple shape is shown in figure d.
Figures e, f, and g show the back material 15 with the tip of the protrusion 16 bent into a seam shape, and Figures h and i show the back material 15 with the rising portion 19 vertical.

This is a back surface material 15 in which a protrusion 16a is formed at a position inward from the side wall 3. Furthermore, one or more ribs (for reinforcement and design improvement of the appearance) as shown in FIGS. 8a to 8d may be formed along the longitudinal direction on the decorative surface 2a of the surface material 1 . . The reason why the front surface material 1 and the back surface material 15 are formed into various shapes is to provide the board itself with one of the following effects: a sealing effect, a reinforcing effect, a spring effect, a straightening effect, etc. Although not shown, at least one of the male connecting portion 6 and the female connecting portion 14 may be located at any position.
Caulking material can also be planted in these areas.

As mentioned above, according to the board according to the present invention,
Unlike the previous model, which used a single thin metal plate, we used a male connector with a sanderch structure, so there was no deformation or separation at the connector, and there was no undulation at the tip, making it a straight edge. The edge is bent at an angle that makes it easy to insert, and the elasticity of the insertion edge itself is used for the engagement force, and the structure is extremely easy to install. In addition, since a protrusion is formed at the end of the female connecting part, a gap can be formed between the insertion edge and the extension part to prevent capillary phenomenon, and rainwater can be prevented from leaking to the back surface of the connecting part. Furthermore, the back material is sandwiched by the surface material at one end and covered and abutted at the other end, thereby preventing expansion and contraction of both members due to temperature and adverse effects caused by expansion and contraction of the foam, thereby providing excellent dimensional stability. In addition, the nail driving part has the feature that the nail driving part has good work efficiency and does not cause damage to the surrounding area because the nail driving part can be driven easily without bounce of the nail due to the reinforcement of the protrusion, the reinforced side wall, and the bent part. Another advantage is that the shapes of the male and female connecting parts and the backing material are hardly deformed, so that a wall body with a beautiful appearance can be formed.
