Description

Description: FIELD OF THE INVENTION The present invention relates to a wall structure that can be used as an inner or outer wall of a building.

2. Description of the Related Art Conventionally, in order to finish a building, especially the inner and outer walls of a building with stone, stone materials such as marble sliced into a plate shape are constructed by a wet method or a dry method. In the wet method, the mortar is backfilled in a state where the stone engraving is exposed on the surface of the frame concrete, and the stone material is held by the stone engraving on the mortar. Further, in the dry method, dowel holes are formed in the stone material, and the base and the dowel holes are fastened with a trigger plate. In this case, the mortar is not backfilled.

However, in the above construction method, since the stone material is 600 mm square and the thickness is about 25 mm, the stone material itself has a considerable weight, and the holding tool has a large load bearing characteristic. It requires 4 or 5 manpower to attach a piece of stone. Moreover, there is a problem that a considerable amount of skilled worker is required, and even if the work is pulled up over time, the construction accuracy varies.

In recent years, the processing technology of stone materials has advanced, and it has become possible to provide thin and lightweight products having a thickness of about 6 mm, but the above-mentioned problems in the conventional method have not been solved at present.

Therefore, an object of the present invention is to make a thin and lightweight stone material that can be processed in recent years easily by a so-called panel-type construction method that does not require mortar backfilling, doweling, or triggers. To provide the structure.

In order to solve the above problems, the wall structure according to the present invention has a base material fixed to the body, a composite material in which a flat plate material is fixed to at least one of the front and back surfaces of the corrugated core material, and a plate shape. It is composed of stone material sliced into pieces and joint material.

The composite material is usually made of a galvanized steel plate, aluminum, etc., and a corrugated core material with a flat plate fixed to the front and back surfaces is lighter and has higher strength than a metal plate of similar thickness. , Excellent in sound insulation, vibration damping, and heat insulation,
It is also non-combustible and waterproof, and has excellent performance as a building material.

By the way, the plate-shaped stone material is fixed on the composite material by means such as adhesion to form a single wall material panel. This wall material panel is arranged on the base material fixed to the frame, and the joint material is fixed to the joint portion by means such as screwing to the base material. The joint material is made of, for example, a metal material such as stainless steel or aluminum having good weather resistance and load resistance.

The fixing of the wall material panel with the joint material is performed by pressing and fixing the edges of the composite material with both shoulders of the joint material, or by pressing and fixing the edges of the plate-shaped stone material.

Example [First Example, see FIG. 1] 1, 2 are base materials, 3 are composite materials, 4 are plate-shaped stone materials, and 5 are joint fittings.

The base materials 1 and 2 are manufactured in a factory to a predetermined size, and are fixed to the skeleton concrete 9 so that the surface of the base material 2 forms a uniform flat surface. The base material 1 is fixed to bolts (not shown) projecting from the skeleton concrete 9, and the base material 2 is fixed to the base material 1 by welding or bolting.

The composite material 3 has a sandwich structure in which the front and back surfaces of the corrugated core material 31 are adhered by the flat plate materials 32 and 32. For example, the corrugated core material 31 is formed by corrugating an aluminum plate having a thickness of 0.2 mm at a pitch of 9 mm. The flat plate members 32, 32 are made of an aluminum plate having a thickness of 0.5 mm, and the two are adhered at the corrugated top so that the total thickness is about 5 mm.

The plate-shaped stone material 4 is obtained by slicing stone material such as marble into a thickness of about 6 mm, and is adhered to the surface of the composite material 3. The size of the composite material 3 is substantially the same as that of the composite material 3, or one composite material 3 can be divided into several pieces and stretched.

The joint fitting 5 is made of a stainless or aluminum molded product and has both shoulder pressing portions 51, 51.

The composite material 3 and the plate-shaped stone material 4 bonded to each other form one wall material panel and are arranged on the base material 2 by the required number, while the joint metal fittings 5 are provided in the joint portions where the composite material 3 is adjacent. It is fixed to the base material 2 with screws 6. At this time, in each wall material panel, the pressing parts 51, 51 of the joint fitting 5 are made of the composite material 3
It is fixed by pressing the edge of the.

[Second Embodiment, See FIG. 2] This second embodiment is similar to the first embodiment in that the base material 1,
2. The composite material 3, the plate-shaped stone material 4, the joint fitting 5, and the screw 6 are used. Here, the wall material panel arranged on the base material 2 is fixed by pressing the edge portions of the plate-shaped stone material 4 by the pressing portions 51, 51 of the joint fittings 5 fixed to the base material 2 with screws 6. To be done.

[Other Embodiments] The wall structure according to the present invention is not limited to the above-mentioned embodiments, and can be variously modified within the scope of the gist thereof.

For example, although waterproofing of the joint portion is sufficient in the first and second embodiments, in order to achieve more completeness, an appropriate seal is provided between the joint fitting 5 and the composite material 3 or the plate-shaped stone material 4. A material may be interposed.

The appearance of the joint portion is not impaired even if the joint fitting 5 is left exposed, but a decorative plate or a sealing material may be fixed or applied on the joint fitting 5 as necessary.

Also, the corrugated core material 31 of the composite material 3 is not limited to the one having a round top, and various shapes such as a trapezoidal shape are conceivable, and two composite materials 3 are positioned so that the corrugations are located in the same direction or in the intersecting direction. It may be used by overlapping.

Further, the wall structure according to the present invention is not limited to the outer wall of the building,
It can be widely applied to inner walls and floors.

EFFECTS OF THE INVENTION As is clear from the above description, according to the present invention, a base material, a composite material, a plate-shaped stone material and a joint material are used, and a composite material and a plate-shaped stone material constitute a wall material panel. Therefore, it does not require backfilling of mortar, formation of dowels, triggers, etc. as in the past, and easily and without being affected by the weather, etc.
Even a craftsman with few years of experience can carry out the construction, and the construction accuracy is made uniform, making full use of the characteristics of the composite material that is lightweight, has high strength, is sound-proof, vibration-damping, heat-insulating, nonflammable, and waterproof. A wall structure can be provided.

Particularly, as shown in the second embodiment, when the joint fitting 5 is provided relatively high, the head of the screw 6 is hidden in the groove, which is aesthetically pleasing, and it is not necessary to separately provide the joint material.
