2. Description of the Related Art A conventional joint device for a floor, in which a joint plate moves upward when a joint portion is narrowed, has a lower surface on the both side walls on the joint portion side which is lower than or equal to the floor surface so as not to prevent the joint plate from moving. Thus, a joint plate moving gap opened to the joint portion is formed.

[0003]

In the conventional joint device for floor, a joint plate moving gap is formed on both side walls so as not to hinder the movement of the joint plate. There is a drawback that it becomes unsightly when covered with the like. Also, in recent seismic isolation buildings, the amount of movement is set to be large, so that the joint plate movement gap becomes large, making it more difficult to see.

The present invention has been made in view of the above-mentioned conventional drawbacks,
It is an object of the present invention to provide a floor jointing device that can reliably cover a joint plate moving gap without hindering movement of the joint plate even when the joint plate moving amount is set to be large, thereby preventing the joint plate from becoming unsightly. .

The above and other objects and novel features of the present invention will become more completely apparent when the following description is read in conjunction with the accompanying drawings. However, the drawings are for explanation only, and do not limit the technical scope of the present invention.

[0006]

In order to achieve the above-mentioned object, the present invention is directed to a left and right building constructed via joints, wherein lower surfaces formed on both joint side walls of one of the right and left buildings are floor surfaces. A rear end portion is attached to the joint plate moving gap opening to the joint portion and a skeleton on the joint portion side of the other building so as to communicate with the floor surface of the other building; Part is supported on the floor of the joint part side of the one building, the joint plate whose both ends enter the joint plate moving gap, and the inner surface of the joint plate moving gap into which both ends of the joint plate enter. A movable joint cover device that can move so as not to hinder the movement of the joint plate constitutes a joint device for floor.
