Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for fixing a wall material of a ceramic plate such as a tile by a dry method using a wall of a building as a base.

[0002]

2. Description of the Related Art As a construction for fixing large tiles and various kinds of porcelain plates to a wall for exterior or interior of a building, holding metal fittings are previously fixed on the wall side and the holding metal fittings are attached to the back surface of the porcelain board. It has been generally practiced to attach a fixing metal fitting to be connected to and to hook the fixing metal fitting to a holding metal fitting.

FIG. 7 shows an outline of an example of a structure for attaching a fixing member to a tile in a conventional construction method.

In FIG. 1 (a), grooves 51 are cut in the upper and lower surfaces of the tile 50, and a bolt 52 and a nut 52a are attached to a fixing metal fitting 52 fixed to the wall in the grooves 51.
This is an example in which the insertion metal fitting 52c joined to the plate 52b connected by is sandwiched, and the back surface of the tile 50 is received and held by the auxiliary plate 52d.

In addition, FIG. 2B shows a two-member fixing bracket in which two grooves 53 are cut on the back surface of the tile 50 with an inclination toward the front side toward the central portion of the tile 50. 54a and 54b are hooked in these grooves 53, and these fixing fittings 54a and 54b are integrated by a screw 55 so that they can be connected to a wall-side holding fitting.

[0006]

In the case where the groove 51 is provided on the upper end surface and the lower end surface of the tile 50, the fixing metal fitting 52 has the insertion metal fitting 52c integrated with the fixing metal fitting 52 which is inserted into the groove 51, whereby the tile 50. Will be loaded. Therefore, if the weight of the tile 50 is large, it is necessary to increase the hooking force by the plate 52b and the fixing metal fitting 52 for holding the tile 50, and the groove 51 is required to be deep. Then, only the upper and lower ends of the tile 50 are joined to the fixture 52, the plate 52b, and the insert 5
Since it is constrained by 2c, the fixing force on the wall tends to cause stress concentration on the groove 51 portion.

As described above, in the construction using the grooves 51 provided at the upper and lower ends of the tile 50, the stress concentration after construction cannot be ignored, especially when the depth of the groove 51 is increased, and the groove 51 is not neglected. There is a high possibility that the load will be concentrated on the remaining part of the notch and the tile 50 will be cracked.

On the other hand, in the case where two grooves 53 are formed on the back surface of the tile 50, even though the groove 53 has an inclination that is not orthogonal to the front and back surfaces of the tile 50, the groove 53 has a relationship with the wall thickness of the tile 50. Can't be too deep. Therefore, there is a limit to the connection strength between the fixing fittings 54a and 54b, and the weight of the tile 50 easily limits the connection.

[0009] Further, the two grooves 53 which are inclined with respect to each other
Since the fixing metal fitting is applied to the groove 53, if the accuracy of the distance between the grooves 53 is poor, the connecting work using one fixing metal fitting takes time. Therefore, tile 50
As shown in the figure, 2 for clearing the precision of the side
Only the method of integrating the fixing brackets 54a and 54b of the members with the screw 55 is adopted, and the complexity of the work is unavoidable.

As described above, in the conventional dry-type installation work of a ceramic plate such as a tile, there are problems that cracks in the tile itself and workability should be improved.

[0011] The problem to be solved in the present invention is to make it possible to dry-process the wall material such as tiles and porcelain plates while the strength of the wall material is sufficiently maintained and the operation is simple.

[0012]
