DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of forming a natural stone such as granite or marble into a plate having a predetermined shape, size or thickness, and attaching a base material to the back of the natural stone. The present invention relates to a building material used by laying a kind of integrally formed floor material on a floor or the like.

[0002]

2. Description of the Related Art In general, vinyl carpets, flocking carpets, wood carpets and the like are generally used as this type of flooring. Also, so-called stone tiles using stone are known.

[0003] When these flooring materials are constructed, they may be laid on the floor surface by using mortar or other bonding material so that the adjacent ones are arranged with good dimensional accuracy while maintaining the planar accuracy of adjacent ones. Is being done.

[0004]

However, the carpet of the prior art described above has a problem in that it has a calm luxury and poor solid feeling due to the characteristics of the material itself. In addition, the stone tile of the conventional example is a work of applying a bonding material each time when performing the work, performing positioning before and after left and right, and attaching the stone tiles one by one while achieving plane accuracy. In addition to the above, there is a problem that the construction period is relatively long due to the so-called wet construction, and the workability of the construction is extremely poor.

[0005] Therefore, in the case of the conventional flooring material, a construction material which can be easily constructed without using skill and uses a natural stone having a luxurious and profound feeling and which can be manufactured relatively easily appears. In particular, they have problems that need to be solved.

[0006]

As a specific means for solving the problems of the prior art, the present invention relates to a building material in which a natural stone material and a base material formed in a predetermined shape and thickness are integrally adhered. Accordingly, the present invention provides a building material having a plurality of grooves formed on the surface of the natural stone material.

In the present invention, the shape and size of the base material are the same as or slightly smaller than the shape and size of the natural stone, and the groove formed on the surface of the natural stone is
Although it does not reach the base material, it is formed to such a depth that cracks are generated along the groove by the pressing force, or it reaches the base material, the predetermined shape of the natural stone is rectangular, one side The length is 250mm or more and the predetermined thickness is 5mm
Not less than 20 mm, and the base material can be one or more of synthetic resin, natural rubber, glass fiber sheet, and carbon fiber sheet that can absorb irregularities such as pebbles and function as a cushioning material. It is included as a configuration requirement.

[0008] The building material according to the present invention uses a natural stone material, so that luxuriousness and profound feeling are brought out. Further, the natural stone material is stuck on the base material, and a plurality of grooves are formed on the surface of the natural stone material. Then, a large number of stone tiles are juxtaposed, and a state in which the stone tiles are juxtaposed juxtaposedly has appeared. The work can be performed in a state where they are arranged in a well-formed manner without requiring any work, so that the workability of the work is remarkably improved.

[0009] In addition, by forming grooves in the natural stone material that reach or not reach the base material, even if the construction site has a slightly wavy unevenness, cracks are formed along the grooves following the unevenness and the unevenness occurs. Since cracks can be absorbed, cracks do not occur at conspicuous positions, and there is no large ups and downs, so that the whole can be laid flat and constructed.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the illustrated embodiments. In the first embodiment shown in FIGS. 1 to 4, for example, a natural stone 1 made of marble, granite or the like is formed as a plate having a predetermined shape and thickness, and has substantially the same shape as the plate-like natural stone 1. And a flexible, thin and strong base material 2 is integrally adhered with an appropriate adhesive.

The shape of the natural stone used in the illustrated embodiment is a rectangle such as a square or a rectangle.
The length of one side is 250 mm or more, and the thickness is 5
mm or more and 20 mm or less. These dimensions can be changed as appropriate depending on the conditions of the place where they are used, the design, and the like.

The flexible thin and strong base material 2 is made of a material that is easily compatible with the natural stone material 1 to be stuck and the floor slab at the construction site, etc. A material having hardness and cushioning function and capable of absorbing unevenness due to the presence of sand or pebbles is used. Examples of the material include a synthetic resin, natural rubber, a glass fiber sheet, a carbon fiber sheet, and the like. If necessary, one or two or more of these sheet materials may be used. The external dimensions of the base material 2 are formed to be substantially the same as or slightly smaller than the external dimensions of the natural stone 1.

After the base material 2 is attached to the natural stone 1 in this way, as shown in FIG. 2, a plurality of grooves 3 are formed on the surface of the natural stone 1 by using a cutting means such as a blade 4 or the like.
To form In this case, the plurality of grooves 3 are formed in a grid-like manner at predetermined intervals in the vertical and horizontal directions, and each part partitioned by the grooves 3 has one tile shape. Therefore, in the illustrated embodiment, the 25 tiles can be visually recognized in a state where they are arranged neatly and precisely.

As the groove 3 to be formed, as shown in FIG. 3A, a V-shaped groove is formed without reaching the base material 2, or as shown in FIG. As shown in FIG. 5A, the U-shaped groove is formed so as not to reach the base material 2, or the V-shaped groove and the small-diameter groove at the bottom thereof are formed as shown in FIG. Is formed without reaching the base material 2. When forming a groove that does not reach the base material 2, the base material 2
A groove may be formed before the adhesive is attached.

In any of these cases, when the floor surface of the construction site is wavy or uneven when laying at the construction site, some unevenness can be absorbed by the base material 2. With respect to the irregularities that cannot be completely absorbed by the material 2, when a pressing force is applied from the surface side of the natural stone material 1 at a position corresponding to the irregularities, FIG.
As shown in FIG. 4 (B) and FIG. 5 (B), a crack 5 is formed along the groove 3 so as to be adapted to unevenness, and a flat portion where the groove 3 is not provided, that is, the natural stone 1 is conspicuous. There are no cracks in the location.

After the building material is laid in this way, even if a crack 5 is formed in the groove 3 at a position deeper than the groove 3 so as to follow the unevenness of the floor surface, the crack 5 is not visible from the outside at all. Since it occurs at the position, the appearance is not impaired by the crack 5. When the floor surface of the construction site is substantially flat, no crack is formed along the groove 3.

Further, as in the second embodiment shown in FIG. 6, for example, a groove 3a having a smaller diameter is formed at the bottom of the V-shaped groove 3 formed on the surface of the natural stone 1. The groove 3 may be formed so as to reach the base material 2 in advance. The same applies to a U-shaped groove. The natural stone material 1 and the base material 2 in this case are substantially the same as those in the first embodiment with respect to the configuration, the attaching means, the cutting formation of the groove 3, and the like, and further form the groove 3a having a smaller diameter. The only difference is in the means for doing so.

Further, unlike the third embodiment shown in FIG. 7, a V-shaped or U-shaped groove is not formed on the surface side of the natural stone material 1 but a small diameter reaching the base material 2 from the beginning. Groove 3a
Can also be formed. Also in this embodiment,
The natural stone material 1 and the base material 2 are substantially the same in configuration and affixing means as in the first embodiment, except for the means for forming the small-diameter groove 3a from the beginning. The grooves 3a having a small diameter are also formed by cutting with a blade or the like, and a plurality of grooves 3a are formed in a lattice pattern in the same manner as the grooves 3.

By forming the small-diameter groove 3a reaching the base material 2 as in the second and third embodiments,
Even if the floor surface of the construction site is wavy and uneven, at the time of laying, it can be arranged without difficulty due to the presence of the small-diameter groove 3a, and as a whole, the construction can be performed in a good appearance it can.

The building material according to the present invention can be applied not only to the floor surface but also to the wall surface.
Since the base material 2 can be cut along a, the size (width) and shape of the building material can be freely changed, and the construction material can be easily constructed in various places.
Furthermore, naturally, even if a part of the natural stone material 1 is conspicuously damaged after laying, the building material according to the present invention may be removed by removing the damaged part of the building material or using a groove. Since the partitioned part can be removed and replaced with a new one, repair work can be easily performed.

In any case, since the building material according to the present invention uses the thin and strong base material 2, the natural stone material 1 can be reduced in thickness to reduce the overall thickness. Even when used in combination with a carpet, it is possible to prevent a step from occurring at the boundary, and the appearance is good after construction, and the safety is high without getting stuck during walking.

[0022]

As described above, the building material according to the present invention is a building material in which a natural stone formed in a predetermined shape and thickness and a base material are integrally adhered, and the surface of the natural stone is By having a configuration in which a plurality of grooves are formed, the part surrounded by the formed grooves is visually recognized as a precisely arranged tile shape, the appearance is good, and natural stone is used Therefore, a luxurious and profound feeling is brought out, and an excellent effect that it can be provided simply and inexpensively compared with a building material in which a plurality of small pieces of stone is pasted on a base material.

In addition, since a plurality of grooves are formed on the surface of the natural stone material, and a base material as an unevenness absorbing material and a cushioning material is adhered, the unevenness of the floor surface at the construction site is slightly wavy. Even if there is unevenness due to sand and pebbles, etc., it can be laid without difficulty following the unevenness.Especially, even if the groove does not reach the base material, Along the cracks, the adjacent parts through the cracks become flexible, thereby giving rise to flexibility and adapting to the unevenness of the construction surface, basically in parts other than the groove Since breakage such as cracks does not occur, accurate and clean construction can be performed without skill, and there is an excellent effect that workability is remarkably improved.

Further, if the natural stone material is partially damaged during use after laying, the building material corresponding to the damaged portion or the damaged portion can be simply peeled off and replaced. It is also ideal for home remodeling, and has an excellent effect that an existing carpet or the like can be peeled off and easily replaced.

Also, by forming the outer diameter of the base material slightly smaller than the outer diameter of the natural stone material, the building material can be spread without gaps, thereby further improving the finished state. It has the effect.
