BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a clamp for mounting a ceramic plate on an outer wall of a building or the like.

[0002]

2. Description of the Related Art In architecture, ceramic tiles (porcelain plates) having excellent durability and design are widely used. In recent years, ceramic plates have become larger due to the development of molding methods and advances in drying and firing techniques, and the possibilities for unprecedented versatile applications have been expanded. However, because of its large size, high reliability is also required for its mounting, and various mounting structures have been proposed. FIG. 4 is a sectional view showing an example of a conventional mounting structure. Hanging claws 3 bent in the same direction are formed at both ends of the clamp 1, and both of the hanging claws 3 are bent at a bending angle closer to each other toward the distal end. On the other hand, a pair of hanging holes 7 are formed on the back surface of the ceramic plate 5, and the hanging holes 7 are formed at an inclination angle B such that they approach each other toward the bottom. The hook 3 is inserted into the hook hole 7 of the ceramic plate 5, and the bending angle A of the hook 3 is more acute than the inclination angle B of the hook hole 7. Therefore, when the hook 3 is inserted into the hole 7, only the tip of the hook 3 is locked at the deepest position of the hole 7.

In the thus constructed ceramic plate mounting structure, when a stress P in the tensile direction (wind pressure load in a negative pressure direction in a building) P acts on the clamp 1, the point of action is the hanging hole 7.
, And the cross section subjected to the shearing force is secured with the maximum cross-sectional area from the deepest position of the hanging hole 7 to the back surface 5a of the ceramic plate 5. Therefore, the porcelain plate 5 has the maximum shear strength against the tensile load.

[0004]

In the conventional porcelain plate mounting structure, only the tip of the hook 3 is hooked at the deepest position of the hook 7, so that the hook 3 is close to the hook near the opening. Void 9
Even if the clamp 1 is deformed due to relative displacement in the plane direction between the skeleton and the ceramic plate 5, the displacement of the hook 3 is absorbed by the gap 9, and no harmful load is applied to the ceramic plate 5. .
However, when the clamp 1 is embedded in the skeleton, the arm 1a (see FIG. 4) is integrated with the cast concrete 11 and makes rigid contact. When receiving a displacement from the arm, the arm 1a follows and deforms, and there is a possibility that a harmful force (local stress causing cracking) may be applied to the ceramic plate 5.
The present invention was made in view of the above situation, even when subjected to displacement from the skeleton side, which is a direction orthogonal to the back of the ceramic plate,
An object of the present invention is to provide a porcelain plate mounting structure using a clamp which can absorb the displacement and does not apply harmful force to the porcelain plate, thereby improving the reliability of the porcelain plate mounting structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a ceramic plate mounting structure using a clamp according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a sectional view showing the mounting structure of the present invention, and FIG. 2 is a perspective view of a clamp fitting provided with an elastic sheet. The same members as those shown in FIG. 4 are denoted by the same reference numerals, and overlapping description will be omitted. The clamp 1 is a strip plate
(See FIG. 2), extending substantially horizontally
Arm 1a, and is erected near the center of the arm 1a.
The buried portion 1b (see FIG. 2) and both ends of the arm portion 1a are
b and a pair of hooks 3 bent at an acute angle to the opposite side.
Has been established. Also, on the back of the ceramic plate 5, a clamp fitting is provided.
A pair of hook holes 7 into which one hook 3 is inserted are formed.
You. The hanging holes 7 are inclined closer to each other toward the bottom.
It is provided at an angle. And the arm 1 on the back of the ceramic plate 5
a is closely aligned, and the buried portion 1 b projects to the back side of the ceramic plate 5.
Buried in the cast concrete 11 on the skeleton side
At the same time, the hook 3 is hooked in the hook hole 7. here
In the clamp 1, the hook 3 is located at the deepest position of the hole 7.
Angle of the hook 3 (see FIG. 4).
) Is more acute than the inclination angle B of the hanging hole 7 (see FIG. 4).
It shall be formed. And especially on the back of the ceramic plate 5
Is the arm 1 of the clamp 1 tightly aligned with the back surface.
a, an elastic sheet 21 made of a rubber plate or the like is stretched.
Has been established. That is, the elastic sheet 21 holds the arm 1a.
Avoid direct contact with the concrete 11
Between the arm 1a and the cast concrete 11
Thus, it acts as a cushioning material.

Further, when the buried portion 1b of the clamp 1 is buried on the side of the skeleton, when the cast concrete 11 enters the hanging hole 7, the hanging claw 3 and the hanging hole 7 are integrated, and the hanging point of the hanging claw 3 is fixed. Is not only at the tip, so that the maximum shear strength cannot be ensured, the gap 9 is eliminated, and the displacement of the hook 3 in the plane direction cannot be absorbed. Therefore, the hook hole 7 after the hook 3 is hooked needs to be sealed in order to secure the gap 9. In this case, a material capable of easily forming a good film by coating, for example, an elastic adhesive 23 is suitable. In addition, when such a hanging hole closing process is performed,
The elastic sheet 21 covers the elastic adhesive 23 and is provided further above (see FIG. 1). On the other hand, the clamp 1
Is formed of a bar material, that is, a so-called spring anchor, the bending angle of the hook 3 is formed to be more acute than the inclination angle of the hook hole 7 as shown in FIG. The arm 1a is covered with an elastic sheet 21 stretched on the back surface of the porcelain plate 5 so as not to come into direct contact with the concrete cast on the skeleton side as described above. Furthermore, in order to obtain the same function and effect as above,
An elastic adhesive 23 is applied to the upper part of the hook 3.

In the ceramic plate mounting structure thus configured, when a relative displacement other than the surface direction between the body surface and the rear surface of the ceramic plate, that is, a displacement in a direction orthogonal to the rear surface of the ceramic plate occurs, the displacement is reduced. Absorbed by the elastic sheet 21, the arm 1a is not deformed, and no harmful force is generated on the ceramic plate 5 due to the deformation of the arm 1a. According to the ceramic plate mounting structure using the clamp of the present embodiment, the displacement in the surface direction is absorbed by the gap 9 and the displacement in the direction orthogonal to the rear surface of the ceramic plate is absorbed by the elastic sheet 21, respectively. 5, the ability to absorb displacement can be improved, and the required strength of the ceramic plate 5 can be reduced. As a result, the thickness of the ceramic plate 5 can be reduced. Further, since the thickness of the ceramic plate 5 can be reduced, weight reduction can be achieved, and furthermore, effective use of resources can be achieved.

[0010]

As described in detail above, according to the ceramic plate mounting structure using the clamp according to the present invention, a displacement occurs in the direction perpendicular to the ceramic plate back surface between the skeleton side and the plate back surface. In this case, since the displacement is absorbed by the elastic sheet, the arm of the clamp is not deformed, and no harmful force is generated on the ceramic plate due to the deformation of the arm. As a result, cracks are less likely to occur in the ceramic plate, and the reliability of the ceramic plate mounting structure can be significantly improved.
