Description of the Related Art Conventionally, edge members are fixed to a pair of skeletons facing each other with a gap, a cover plate is installed between both edge members to cover the gap, and a packing is brought into contact with the surface of the cover plate. A sandwich type expansion joint device sandwiched between a cover body and an edge body is used.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a prior art, since the cover plate is composed of a single sheet, for example, when the skeleton is displaced due to an earthquake or ground subsidence, the cover plate abuts the edge member or the cover body. Therefore, the relative amount of relative displacement between each body that can be tolerated is small, and in order to increase the amount of tolerable displacement, the cover plate should not come into contact with the edge material that holds the cover plate and the cover body. In addition, the space between the edge material and the cover body must be increased,
There is a contradictory problem that the edge material and the cover body are enlarged.

Therefore, an object of the present invention is to provide a pinch type expansion joint device capable of allowing a large relative displacement between each skeleton without enlarging the edging member and the cover body. is there.

Means for Solving the Problems According to the present invention, an edge member is fixed to two adjacent frame members with a gap therebetween, and a cover member is fitted to each edge member. In the sandwich type expansion joint device for elastically sandwiching a cover plate arranged across each body to close the gap, each cover plate is composed of a plurality of sheets, and each cover is arranged adjacent to each other. The plate includes a flat main body portion sandwiched by the edge member and the cover body, a hanging piece protruding toward the gap side from one end portion of each main body portion abutting each other, and a hanging piece from the main body portion An inwardly extending piece that extends toward the end is formed, and each cover plate has a fitting groove formed by the main body portion, the hanging piece, and the inwardly facing piece, and a pair that fits into the fitting groove. Having a fitting part and a connecting part for connecting the fitting parts It is a pinching-type expansion joint device characterized in that it is by connexion connected to a connecting member made of sexual material.
