Description

TECHNICAL FIELD The present invention relates to a large-scale building material to be installed on a wall surface of a building or the like.

(Prior Art and Its Problems) Conventionally, as a large building material to be installed on the outer wall of a building, for example, there is a large building material K as shown in the perspective view of the main part in FIG.
A plurality of tiles 2, 2 and 2 are attached to the front surface side of the concrete 1 to form a large plate, and such a large building material K is formed in a wooden frame F as shown in FIG. 5, for example. be able to. That is, the tiles 2 and 2 are arranged on the bottom side of the wooden frame F with the temporary joint material 3 interposed, and the concrete 1 is placed from above the concrete 1 and the tile 2
Can be attached and molded, but, for example, in order to increase the joint strength between the concrete 1 and the tile 2, a metal fitting 5 is fixed to each tile 2 via a pin 4, and the metal fitting 5 is placed in the concrete 1. The structure may be embedded. However, when such a structure is adopted, when the metal fittings 5 are fixedly mounted on the tiles 2 and 2, engaging holes are provided in the tiles 2 and 2, and Although the metal fitting 5 is inserted into the engaging hole to be integrated, stress may be concentrated on the mounting portion of the metal fitting 5 to the tile 2 due to heat and shrinkage force generated when the concrete 1 contracts, and this concentrated stress There has been a problem that damage, cracks, etc. occur at the periphery of the engaging hole of the tile 2, and the tile 2 is damaged and peeled off from the concrete 1.

(Means for Solving the Problem) The present invention has been devised in view of the above conventional problems, and an object thereof is not to provide a large building material having a structure capable of favorably preventing damage to tiles, etc. The gist is to engage the tip of the metal fitting from the back surface side of the tile in the engagement hole formed on the back surface side of each tile arranged in a plurality of rows and form the tiles in the orthogonal shape from the side surface side of each tile. A large-scale building material molded by fixing the tip of the metal fitting in the engagement hole by driving a pin into the pin hole, driving concrete on the back side of each tile, and burying the metal fitting in the concrete. That is, the cushioning member having elasticity is interposed in the engaging portion between the engaging hole of each tile and the metal fitting.

(Operation) When the tip of the metal fitting is engaged and fixed to the engaging hole of each tile, an elastic cushioning member is interposed between the engaging portion of the engaging hole and the tip of the metal fitting, so that the When concrete is placed on the back side and large building materials are molded,
Even if stress is generated around the engaging hole of the tile through the metal fitting due to various heat, shrinkage stress, etc., the cushioning member absorbs these stresses and prevents damage around the engaging hole of the tile. It is possible to obtain a large building material in which concrete and tile are firmly integrated.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a main part on the back surface side of a tile 2 which constitutes a large building material. As shown in the drawing, a blind-shaped engaging hole 2a that opens to the back surface near the four corners of the tile 2 on the back surface side. Further, pin fitting holes 2b are formed orthogonally to the engaging hole 2a from the side surface side of the tile 2, and are formed in the engaging hole 2a from the rear surface side, for example, in the shape of L rods. The tip of the metal fitting 5 can be engaged, and in this engaged state, the pin 4 is driven into the pin fitting hole 2b from the side surface side, so that the pin hole 5a formed at the tip of the metal fitting 5 is formed.
The pin 4 penetrates through the inside, and the metal fitting 5 is attached to the tile 2 through the pin 4.
Can be fixed to.

In this example, the cushioning member 6 is mounted in the engagement hole 2a in advance, the tip of the metal fitting 5 is inserted into the cushioning member 6 in this state, and the pin 4 is driven into the cushioning member 6 from the side in this state. The metal fitting 5 is fixed to the tile 2 via. The cushioning member 6 is formed of a material having elasticity such as urethane rubber into a tubular shape or a bottomed tubular shape as shown in FIG. 3 (a) or (b). The dimensions are formed to be substantially the same as the inner diameter of the engagement hole 2a, and the inner diameter is formed to be substantially the same as the outer diameter of the metal fitting 5.

As described above, as shown in FIG. 5, the tile 2 is arranged on the bottom surface side of the wooden frame F with the tip of the metal fitting 5 fixed to the tile 2 by the pin 4 with the cushioning member 6 interposed in advance. Can be installed and concrete 1 can be cast from the upper side to form a large building material, as shown in the enlarged sectional view in FIG.
The metal fitting 5 is embedded in the concrete 1,
The adhesive strength between the tile 2 and each tile 2 is strengthened by the metal fitting 5, and the tile 2 is prevented from peeling off from the concrete 1. Also, in this example, concrete 1
Even when the metal fitting 5 receives stress due to heat, shrinkage, or the like generated at the time of hardening the resin, and the stress is concentrated in the engaging hole 2a of the tile 2, the elastic force of the cushioning member 6 absorbs this stress, The damage around the engagement hole 2a is satisfactorily prevented. Therefore, the concrete 1
Further, the tile 2 is firmly integrated, and a large-sized porcelain plate with high strength can be obtained.

In addition, when a large porcelain plate shaped in this way is constructed on the wall surface of a building, etc., it is well buffered even when shrinkage stress etc. occurs between concrete 1 and tile 2 due to heat etc. due to long-term use. The elasticity of the member 6 exerts a cushioning function to prevent the tile 2 from being damaged, and the tile 2 is well prevented from peeling off from the concrete 1, and a large-sized building material having durability can be obtained.

In FIG. 2, by removing the temporary joint material 3 at the time of releasing the mold, a beautiful joint can be formed between the tiles 2 and 2 from the surface side, and a large-sized building material having an aesthetic appearance can be obtained.

In addition, in this example, although the metal fitting 5 is illustrated as a rod-shaped one,
The metal fitting 5 may be plate-shaped, and in that case, the cushioning member 6 may be formed into a plate shape or the like corresponding to the tip shape of the metal fitting. It can be changed as appropriate depending on the shape such as 5. Further, the material of the cushioning member 6 is not limited to urethane rubber, but may be any material having appropriate rigidity and elasticity.

(Effect of the invention) The large-sized building material of the present invention is such that the tip of the metal fitting is engaged from the rear surface side of the tile into the engagement hole formed on the rear surface side of each tile arranged in a plurality of rows, The tip of the metal fitting is fixed in the engagement hole by driving a pin into the pin hole formed orthogonally to the engagement hole, and concrete is placed on the back side of each tile to put the metal fitting in the concrete. It is a large building material that is molded by being embedded, and by inserting an elastic cushioning member in the engaging portion between the engaging hole of each tile and the metal fitting, heat and shrinkage between the concrete and tile can be achieved. Even when stress is generated due to the effect of, for example, the stress concentrates around the engaging hole of the tile through the metal fittings, the cushioning member absorbs these stress well, and damage around the engaging hole is prevented. It is a good preventive measure and will prevent tile damage This has the effect of preventing a tile from being peeled off from concrete due to damage or the like, and being a large-scale building material having excellent strength and durability.
