DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint device for a floor covering joints of floors of right and left buildings built through joints.

[0002]

2. Description of the Related Art Conventionally, this type of floor joint device is composed of a pair of supports provided on the floor surfaces of left and right buildings which support both ends of a joint plate covering the joint portion so as to be slidable in the left-right direction. It is configured.

[0003]

In the conventional joint device for floors, the amount of sliding movement between both ends of the joint plate and a pair of supports for supporting both ends of the joint plate swings in different directions due to an earthquake or the like. Because of the movement amount, if it is attempted to move the joint by the joint size, the whole is 3 mm of the joint size.
If the size is not set twice, the swinging motion cannot be absorbed, and there is a disadvantage that the size and cost are increased.

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 joint device that is simple in structure, can be downsized, can be easily installed, and can be manufactured at low cost even if it can cope with large swinging motion.

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]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a support recess formed on a joint-side floor of one of right and left buildings built through joints. A joint plate supporting bracket movably mounted, and a slide supporting bracket fixed to a slide recess formed on a floor on the joint side of the other building of the left and right buildings, and an inclined joint formed on an inclined surface. And one end is rotatably attached to the joint plate support bracket, the other end is supported by the slide support bracket and covers the joint and the slide support bracket, and the upper surface is substantially the same as the floor surface of the left and right buildings. A joint plate for a floor is constituted by a joint plate serving as a surface, and a joint plate pushing-up mechanism for pushing up the joint plate on one building side so that the joint plate becomes a horizontal plane when the size of the joint portion is reduced.
