BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device for a structure such as a stone used for an outer wall, an inner wall, a ceiling wall, etc. of a building or a wooden structure.

[0002]

2. Description of the Related Art Conventionally, as this kind of machine, the actual construction of Shokai 63-7
According to Japanese Patent No. 3430, a vertical portion of an L-shaped hanging metal fitting is fixed to a wall surface of a building, one end of a receiving metal fitting is attached to a horizontal portion of the L-shaped hanging metal fitting by a bolt and a nut, and the other end of the receiving metal fitting. Is provided with a small edge surface of a stone, and a hole provided in the small edge surface of the stone is passed through a threaded through hole provided in the receiving metal fitting, and a screw portion is provided in the head and the vicinity of the head. And a connecting screw having a pin portion at the tip of the screw portion is inserted, and in the gap between the upper hole portion and the inserted connecting screw, an adhesive agent is used to fix the connecting screw in the hole portion to the wall surface of the stone material. Mounting structures have been proposed.

[0003]

In the above prior art, the hanging metal fitting fixed to the wall surface and the receiving metal fitting fixed to the stone material must be connected by bolts and nuts between the wall surface and the stone material. , This connection work is difficult and time-consuming, and because of the connection structure of the bolts and nuts, a space of 70 mm width or more is required between the wall surface and the stone material, which increases the dead space. When stacked, a gap is created between the upper and lower edge surfaces by the horizontal part of the metal fitting, so that there is a problem that the joint part appears by closing this with a filler such as mortar and the aesthetics is inferior. Further, in the above-mentioned conventional technique, there is a problem that the work requires skill.

Further , as described in the above publication, a stone material is applied to the wall surface.
If you use vertically bent metal fittings to connect,
When a force is applied from the outside, this force is due to the elasticity of the metal fitting itself.
Is hard to be absorbed. Therefore, the distortion remains as it is on the wall
The load on the fixing part of the metal fitting to the
It is easy to cause damage, and the metal fitting itself
Deformation is unlikely, but a force exceeding its elastic limit is applied
Then, there is a problem that plastic deformation and fracture are likely to occur.

The present invention solves the above-mentioned problems, has an excellent aesthetics without showing joints, can easily perform construction work, and has high resistance to external force applied to structural materials such as stones. An object is to provide a connecting device for a structure .
