Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a stone panel for forming a floor, wall, ceiling, etc., and an improvement in a method for attaching the same.

(Prior Art) A method of attaching stones or tiles as a covering to a floor or wall has been conventionally used. That is,
One method was to apply a soft layer of cement mortar, etc., to improve the compatibility between the base material and the stone or tile before it hardened, and at the same time to press them together to adjust the surface irregularities.

However, there is a delicate know-how regarding the fluidity of cement mortar, and construction of stone or tile walls requires skill, as well as special tools and materials. Furthermore, during construction, it takes time for the cement mortar to harden after the stones or tiles are pressed together, and at the same time, it is extremely difficult to modify or adjust the cement mortar once it has hardened.

In order to improve these shortcomings, panels with stone attached to them have recently been developed as covering materials for floors and walls in order to make them lighter and easier to construct.For example, panels in the form of composite artificial marble panels have been developed. A construction method (Utility Model Application No. 60-25450) has been proposed.

In addition, recently, a method called the base net construction method, in which a base net is attached to a base surface and pasted on top of the base, has been put into practical use as a method for attaching tiles.

(Problems to be Solved by the Invention) However, the so-called wet installation method for attaching natural stones, tiles, etc. using cement mortar or polymer cement mortar requires the skill of the operator, and distortions and lifting may occur. If it failed, it would be necessary to use a large-scale polishing machine and rework it.

Furthermore, for artificial marble panels and natural marble panels, the maximum variation in marble thickness is 3 mm.
Due to the above reasons, the overall thickness of the panel itself varies, and combined with the unevenness of the base, it takes a considerable amount of time to achieve a uniform surface height, and even if it is possible, the result is poor quality. Ta.

In addition, JIS standards are also applied to artificial stones such as tiles.
- Interior tiles ± 0.7 mm, exterior tiles ± 1.5 mm, floor tiles ± 1.5 mm, as specified in A-5209;
There is a production dimension tolerance of mosaic tile ±0.8mm and tile thickness.

Therefore, there was a maximum dimensional width of 3 mm, and this difference had to be adjusted.

(Means for Solving the Problems) In view of the above-mentioned problems, the present inventors provided a convex portion and a concave portion on the side surface of the base material, and provided a cushioning material on the bottom surface of the base material or the convex portion. The optimal installation method is to use a stone panel and fit the convex and concave portions into each other, and to eliminate surface irregularities and make the surface uniform by partially adjusting the convex and concave portions and the cushioning material. He found out. In other words, by applying creative ideas to the panel base material of these natural stone slabs and artificial stone slabs, it is possible to temporarily fix the panel, and when temporarily fixing, the panel surface can be adjusted stably and uniformly to match the irregularities of the base. We have come up with an installation method that can do this.

The specific means in the first invention is as follows:
To explain with the reference numerals used in the examples, "a stone plate for forming a wall surface, a floor surface, etc., comprising a base material 1 and a stone plate 2 of the same size attached to the upper surface of the base material 1" In the panel 10, the base material 1 is provided with a convex portion 4 extending on at least one side thereof, protruding outward from the edge line 1b of the upper surface of the base material, and having a lower surface flush with the lower surface of the base material 1. , this convex part 4 is provided on the opposite side of the base material 1 to which it is extended, is cut inward from the edge line 1b, and is fitted into the convex part 4 of another base material 1. In addition, at least the lower surface of the convex portion 4 is provided with a heat sink to buffer against unevenness on the wall and floor. A slate panel 10 characterized in that it is provided with a cushioning material 9 made of a foam made of plastic resin or a fibrous non-woven fabric processed by vacuum packing and packaged after removing the air inside. , "a convex portion 4 on at least one side that protrudes outward from the edge line 1b of the upper surface and whose lower surface extends flush with the lower surface of the base material 1; and the opposite side from which the convex portion 4 extends. A concave portion 5 cut inward from the edge line 1b.
In an installation method for forming a wall surface, floor surface, etc., using a plurality of stone slab panels 10 in which stone plates 2 of the same size are attached to the upper surface of a base material 1 having at least a convex portion 4. A cushioning material 9 made of thermoplastic foam or fibrous nonwoven fabric is vacuum-packed and packaged with the air removed, and the cushioning material 9 is unwrapped. The convex portion 4 is temporarily fixed to the wall or floor using nails or wood screws 7 while providing a buffer against unevenness of the wall or floor, and the base material 1 of the temporarily fixed stone board panel 10 is
A method for attaching a slate panel characterized by assembling a plurality of slate panels 10 in succession by fitting the convex portion 4 provided on the base material 1 of another slate panel 10 into the concave portion 5 of the slate panel. ”.

(Function of the Invention) Next, to explain the function of each invention, first, in the slate panel 10 according to the first invention, the base material 1 is provided with an edge line on the upper surface of the base material extending on at least one side thereof. 1b and a convex portion 4 whose lower surface is flush with the lower surface of the base material 1;
Since the concave portion 5 is provided on the opposite side of the base material 1 to which the base material 1 is extended and is cut inward from the edge line 1b, the convex shape of the other base material 1 of the concave portion 5 is By being fitted into the part 4, the stone plate 1
It is possible to assemble a plurality of 0's in succession.

In addition, in this slate panel 10, a cushioning material 9 is provided on the lower surface of the base material 1 or the convex portion 4 to cushion unevenness of the wall surface or floor surface.
This cushioning material 9 makes it possible to temporarily fix the slate panel 10 according to the irregularities of the base, and when temporarily fixing, the panel surface can be stabilized and adjusted uniformly according to the irregularities of the base. It has become possible to do so easily.

In particular, this cushioning material 9 is made by vacuum-packing a foam made of thermoplastic resin or a fibrous nonwoven fabric,
Since the interior air is removed and the package is packaged, the entire slate panel 10 before construction is compact. This cushioning material 9 creates a large gap between the slate panel 10 and the base.
If there are gaps, punch holes in the packaging and let air in. This will increase the volume of the thermoplastic resin foam or fibrous nonwoven fabric, allowing the panel surface to conform to the irregularities of the base when temporarily attached. This makes it possible to easily perform stable and uniform adjustments.

In addition, in the method of attaching a stone board panel in the second invention, the concave portion 5 and the convex portion 4 provided on the base material 1 are fitted and temporarily fixed to a wall surface etc. with wood screws 7, etc. Sometimes, the cushioning material 9 provided on the lower surface of the base material 1 or the convex portion 4 can be used to buffer unevenness on the wall or floor surface, and the above-mentioned ingenuity can be applied to the panel base material of artificial stone slabs. This makes temporary fixing possible, and during temporary fixing, the panel surface can be stabilized and evenly adjusted to match the irregularities of the base.

In other words, in particular, the cushioning material 9 used in this installation method is a foam made of thermoplastic resin or a fibrous nonwoven fabric that is vacuum-packed and packaged after removing the air inside. The entire slate panel 10 is compact. This cushioning material 9 creates a large gap between the slate panel 10 and the base.
If there are gaps, punch holes in the packaging and let air in. This will increase the volume of the thermoplastic resin foam or fibrous nonwoven fabric, allowing the panel surface to conform to the irregularities of the base when temporarily attached. This makes it possible to easily perform stable and uniform adjustments.

Therefore, in this method of attaching the stone slab panel, there is no need to use a large-scale polishing machine to grind the stone slab to make the surface of the stone slab panel uniform, and the base material itself is easy to process. This is done by adjusting the processing of the concave portion, convex portion, or cushioning material.

(Example) The slate panel 10 and its attachment method according to the present invention will be described in detail below using an example in which the example is used on a wall surface. In this case, the method for attaching the slate panel of the second invention will be explained at the time of explanation of each component of the slate panel 10 of the first invention.
I will explain them simultaneously and in parallel.

Note that the following numerical values are illustrative for examples, and are not limited to these numerical values.

First, regarding the slate panel 10 of the first invention, FIG. 1 is a perspective view of this slate panel 10. As shown in the exploded perspective view of FIG. 2, the slate panel 10 is made up of two types of plate-shaped materials, a base material 1 and a slate 2. A stone plate 2 is attached using an adhesive 3.

In this embodiment, the base material 1 is made of a wood-based material such as particle board or plywood, and is formed into a predetermined size and thickness so that the surface of the entire panel 10 is uniform, taking into consideration variations in the thickness of the stone slab 2. The surface and side surfaces are ground and polished, so to speak. Not limited to wood-based materials, as long as they have enough strength to withstand use and can form convex portions 4 and concave portions 5 on the edges as described below, such as plywood, particle board, inorganic cement board, and inorganic fibers. It may be made of any material such as a composite plate, a thermoplastic resin plate, a thermosetting resin plate, or a composite material or a combination of these materials.

In this embodiment, the stone plate 2 is made of natural marble processed into a thin plate with a thickness of 7 mm. However, it is not limited to natural marble; metamorphic rock, igneous rock, or artificial stone plates such as tiles may be used depending on the purpose. It's okay. The thickness of the stone plate 2 used in this case is preferably about 2 mm to 20 mm in view of the balance between strength and weight.

The adhesive 3 for bonding the base material 1 and the stone slab 2 is preferably a urethane resin, an epoxy resin, a vinyl acetate resin, a synthetic rubber resin, or a silicone resin, and the adhesive 3 is preferably applied to the top surface of the base material 1 by spatula coating or This is done by spray application or roll coating. The coating amount is preferably about 100 to 400 g/m ² .

In the stone panel panel 10, as shown in FIGS. 1 and 2, a convex portion 4 extending outward from the edge line 1b of the upper surface of the base material 1 extends on at least one side of the base material 1. A recessed portion 5 cut out inward from the edge line 1b is provided on a side surface opposite to the side surface on which the convex portion 4 is provided.

The convex portion 4 has its lower surface 4a flush with the lower surface 1a of the base material 1, as shown in the AA sectional view of FIG. Therefore, as shown in FIG. 7, wood screws, nails 7, etc. are driven into the convex portion 4 of the stone panel 10, and temporary fixing to a pillar or the like 6 provided on the wall surface 20 can be stably and reliably performed.

Since the convex portion 4 protrudes outward from the edge line 1b on the top surface of the base material 1, it will not interfere with the natural marble 2 or the base material 1 body when temporarily fastening with wood screws 7 or the like. do not have.

In this embodiment, the convex portion 4 is provided with a plurality of through holes 8 in the vertical direction.
By easily inserting the wood screws 7, etc., it is easier to temporarily fix the stone panel 10 to the wall surface 20.

FIG. 5 is a perspective view showing another embodiment of the stone panel 10 in which the shapes of the convex portions 4 and concave portions 5 and the number of vacuum-packed cushioning materials 9 are changed, and FIG. It is a perspective view of still another example of the stone board panel 10 which provided the part 4 and the recessed part 5 in the four sides of the side surface.

As shown in FIG. 8, on at least the lower surfaces 1a and 4a of the convex portions 4 of the slate panel 10 according to the present invention, a cushioning material 9 is provided to facilitate uniformity of the surface of each slate panel 10. It is provided. This cushioning material 9 includes the base material 1 and the lower surface 1 of the convex portion 4.
It may be implemented by providing it in a, 4a.

This cushioning material 9 is formed by vacuum-packing a thin plate of foamed urethane with a polyethylene film 19 over both the base material 1 and the convex portion 4, and is pasted with the same adhesive 3 as the adhesive 3 described above. In this embodiment, four cushioning materials 9a, 9b,
9c and 9d. These cushioning materials 9 are not limited to foamed urethane, but also include thermoplastic resins themselves such as foamed styrene and foamed polyethylene, materials mixed with inorganic materials, organic fibers such as silicone rubber, polyester fibers, and natural fibers such as cotton. Any material that contains air, such as a woven fabric made of can. These materials are cut into appropriate sizes and preferably pasted at four or more locations.

In this embodiment, the air inside these cushioning materials 9 is extracted in advance by a vacuum packaging machine equipped with a vacuum pump, which is widely used for food packaging, etc., and then packed with polyethylene film 19 to reduce the thickness to the minimum. I am using crushed ones. Such a packed cushioning material 9 has the ability to freely return to its original thickness due to the restoring force of the fibers, etc. by tearing the polyethylene film 19 during panel installation. Therefore, in this embodiment, the difference can be freely covered up to nearly 5 mm. For example, for a 3.5 mm spunbond nonwoven fabric made of polyester fibers, the gap can be adjusted from 0.5 mm to 1 mm, with a maximum thickness of 3 mm, when it is vacuum film packed. This cushioning material 9 constantly pushes up the surface of the stone panel 10 and makes it stable, making construction easy.

Further, the number of the vacuum pack-formed cushioning materials 9 is not limited to four as in this embodiment, and may be changed as appropriate depending on the size of the stone panel 10. FIG. Another embodiment in which six pieces of material 9 are provided is shown.

This vacuum-packed cushioning material 9 is placed between the stone panel 10 and the pillars 6, and serves as a cushion. In other words, slate panel 10
When installing the stone plate 2 to the wall surface 20, if the base framework such as the pillars and body frame 6 of the wall surface 20 is uneven, or if the thickness of each stone panel is uneven, the surface of the stone panel 2 may slump and cause damage to the base. Since it may be difficult to uniformly adjust the surface of the stone slab 2 by only processing the material part 1, when constructing the stone slab panel 10, first temporarily secure the stone slab panel 10 with wood screws 7, etc. .

At that time, the slate panel 10 is
Since the surface is pushed up toward the surface, the surface becomes stable and can be easily adjusted and made uniform by actual processing (see Fig. 8). When attaching to the wall surface 20, it is preferable to apply adhesive 3 to the frame including the pillars and body frame 6 before fixing with the wood screws 7.

FIG. 9 shows a stone panel 10 according to the embodiment shown in FIG.
It is a perspective view showing a state in which a wall surface 20 is sequentially formed by using a plurality of sheets and fitting the above-described convex portions 4 and concave portions 5 into each other and making them continuous in all directions. As shown in this figure, temporary fixing can be easily achieved by bringing a wood screw or the like 7 into the convex portion 4, and the surface of the slate panel 10 is pushed up and stabilized by the vacuum-packed cushioning material 9. After temporarily fixing, there is no need to grind the stone plate 2 itself, and the convex part 4 and the concave part 5 can be partially corrected, or by tearing the vacuum pack film of the vacuum pack-formed cushioning material 9. Therefore, it is possible to easily adjust the surface uniformity of the panel 10.

When the slate panel 10 is used as a wall material, the convex part 4 and the concave part 5 fit together, so that the individual slate panels 10 in a vertical state are stable and do not wobble, making it easy to install. .

In the slate panel 10, when natural stone is used, it has a luxurious feel and texture, can increase added value, and is not limited in its usage. Of course, since it is made of thin plate-shaped natural stone, its weight is less than half that of conventional stone, so it is an installation method that improves workability due to its weight reduction and significantly shortens the construction period.

In this embodiment, the assembly of the stone panel 10 on the wall surface 20 has been described, but it goes without saying that it can be similarly applied to the floor surface, ceiling surface, etc.

A convex portion 4 that is unified with the convex portion 4 is provided on the opposite side of the base material 1 on which the convex portion 4 is extended, and is cut inward from the edge line 1b, and a convex portion of the other base material 1 is provided. It has a recessed part 5 that can be fitted into the part 4 to assemble a plurality of stone plates 2 in succession, and at least the lower surface of the convex part 4 is provided with a recessed part on the wall or floor. In order to provide cushioning for the parts, the cushioning material 9 is made by vacuum-packing a foam made of thermoplastic resin or a fibrous non-woven fabric, removing the air inside, and packaging it. By driving wood screws, etc. into the convex part that fits into the concave part, it can be easily temporarily fixed to a wall, etc., and the surface of the slate panel can be constantly pushed up and stabilized by the cushioning material, making it easy to install. The slate panel 10 that is easy to use can be provided with a simple structure.

In other words, according to this slate panel 10, if there is a large gap between the slate panel 10 and the base, if a hole is made in the packaging of the cushioning material 9 and air is introduced, the thermoplastic resin can be removed. The volume of the foam or fibrous nonwoven fabric increases, and when temporarily attached, the panel surface can be stabilized to match the irregularities of the base, and uniform adjustment can be easily performed.
