DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a floor joint device of this type has a channel-shaped base rail fixed to a recess formed near a joint part of a floor part of a left and right building, and a joint part side part of the base rail. The joint plate has both sides supported, and cover plates respectively attached to the base rails so as to cover upper portions of both sides of the joint plate.

[0003]

In the conventional joint device for floor, when the right and left buildings swing in different left and right directions due to an earthquake or the like, the joint plate and the support portion of the base rail slide and move. However, if the left and right buildings swing in different front and rear directions, the joint plate collides with and damages the wall surfaces of the left and right buildings, so a gap must be provided, and if the gap is provided, it becomes unsightly There was a disadvantage.

The present invention has been made in view of the above-mentioned conventional drawbacks,
Even if the left and right buildings swing in front and rear and left and right directions different from each other due to an earthquake or the like, the objective is to provide a floor joint device that smoothly follows the swing motion without any gaps at both ends and is not damaged. And

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]
