Conventional technology Conventionally, there is a method of covering a concrete wall cast in place with a decorative stone plate from a cosmetic and corrosion-resistant point of view, and as a method of attaching the decorative stone plate, conventionally, a mortar or the like is adhered to the concrete wall surface. In order to further ensure the adhesiveness between the adhesive and the decorative stone slab, a plurality of fixtures are provided on the back surface of the decorative slate, and integrated at each corner of the decorative stone slab. And a plurality of fixtures are embedded in an adhesive material such as mortar, and these fixtures are used as main attachment portions to directly hold a decorative slab.

Problems to be solved by the present invention By the way, the decorative stone slab used in the above-mentioned mounting method has recently become larger in terms of working surface and aesthetic appearance, and with the rise of buildings, At the same time, the weight is reduced and a thinner one is used. Therefore, when such a large decorative stone slab is attached by the above-described method, the distance between the fixtures becomes considerably long, and when the adhesive material is dried and shrunk during curing, the amount of shrinkage between the fixtures increases. However, there is a problem that the contraction force acts on the decorative stone slab through the fixture, causing a large stress on the decorative stone slab and causing the decorative stone slab to crack. Such cracking due to stress is also caused by a difference in the coefficient of thermal expansion between the decorative stone slab and the adhesive such as mortar in the adhesive.

物の躯体に取付けられる。FIGS. 3 and 4 show the mounting structure of the decorative stone slab in the precast concrete method. First, as shown in FIG. 3, a decorative stone plate (1) provided with the separation layer (2) is placed on a bottom plate of a mold (5) with its back surface 1 (a) facing upward. After the concrete is poured into the mold (5) in a predetermined amount, the concrete is cured, and the concrete is cured and the mold (5) is removed. Thereby, the fixture (3) and the auxiliary fixture (6) fixed on the back side of the decorative stone slab (1) are embedded in the hardened concrete (4),
As shown in FIG. 4, a precast concrete slab whose surface is covered with a decorative stone slab (1) is molded. And
The precast concrete slab is attached to the building frame by appropriate means.

（８）は目地を示す。In the case of the above mounting, the decorative slab (1) can secure sufficient mounting (adhesion) strength only with the mounting tool (3), and the auxiliary mounting tool (6) is made of concrete or the like. It has an auxiliary role of improving the adhesion and at the same time restricting the stiffness and inclination.

れが防止される。When the concrete (4) shrinks due to its hardening during or after the molding, the contraction force acts on the fixture (3) and the auxiliary fixture (6).
The contraction force acting on the fixture (3) merely acts as a force for clamping the outer surface of the fixture (3),
The contraction force acting on the reinforcing fixture (6) is absorbed by the deformation of the auxiliary fixture (6) due to the deformability or elasticity of the auxiliary fixture (6), and the decorative stone plate (1)
The contraction force is not transmitted to Therefore, the stress caused by the shrinkage force is not generated in the decorative stone plate (1) between the fixture (3) and the auxiliary fixture (6) and between the auxiliary fixtures (6), but by the stress of the decorative stone plate. Cracks can be prevented. In addition, since the separation layer (2) is interposed on the surface other than the installation portion of the mounting device (3) and the auxiliary mounting device (6), the decorative stone slab (1) on the surface is made of concrete (4). Not adhered. Therefore, the shrinking force of the concrete (4) on the surface is not transmitted to the decorative stone slab (1), and cracking due to stress on the surface is prevented.

十分な取付強度が確保できるようになっている。FIG. 5 shows the mounting structure of a decorative stone slab in the mortar method, in which the above-mentioned mounting tool (3) and auxiliary material are applied to an adhesive layer (7) such as mortar applied to the wall (9) of a building. The decorative stone slab (1) is directly mounted with the fixture (6) buried and the back (1a) side closely contacted. In the case of such a mounting structure, similarly to the case of the precast concrete method, the decorative stone slab is used. In (1), sufficient mounting strength can be ensured only by the mounting tool (3).

を防止できる特長がある。C. Advantageous Effects of the Invention As described above, according to the present invention, since the mounting tool serving as the main mounting portion is provided only at the center of the decorative stone slab, an adhesive layer such as concrete or mortar for attaching the decorative stone slab is provided. Even when drying and shrinking during curing, the shrinking force only acts as a force to tighten the outer surface of the fixture,
The stress acting on the decorative stone slab due to the contraction force is extremely small, and as a result, there is a feature that the decorative stone slab can be prevented from cracking due to this kind of stress.
また、化粧用石板の裏面に変形性或いは弾性を有する
補助取付具を一体に固着し、これを接着層中に埋設する
ことにより、前記の応力割れを招くことなく、該化粧用
石板の接着層に対する密着性を良くすることができる上
に化粧用石板の剥離を防止できる特長がある。Further, a deformable or elastic auxiliary fixture is integrally fixed to the back surface of the decorative stone slab and embedded in the adhesive layer, thereby preventing the above-mentioned stress cracking without causing the adhesive layer of the decorative stone slab. In addition to being able to improve the adhesiveness of the decorative stone plate, it is possible to prevent peeling of the decorative stone plate.
また、化粧用石板と接着層間にガラス繊維等の分離層

粧用石板の応力割れを更に防止できる特長がある。In addition, by providing a separation layer of glass fiber or the like between the decorative stone slab and the adhesive layer, even if the back surface of the decorative stone slab is rough, the adhesion between the decorative stone slab and the adhesive layer is prevented, and when the adhesive layer is cured. It is advantageous in that stress is prevented from being generated in the decorative stone slab due to a difference in thermal expansion coefficient between the decorative stone slab and the adhesive layer between the decorative stone slab and the adhesive layer, thereby further preventing stress cracking of the decorative stone slab.
