Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Conventionally, this kind of passage joint device is fixed to one base rail fixed to the joint side end of the passage of one building and to the joint side end of the passage of the other building. The other base rail, the joint plate that covers the joint portion where the other side rail and the portion of the one side rail are supported by the other base rail, and the upper portion of both side portions of the joint plate are covered. The one base rail and the other base rail include one and the other cover plates attached to the joint plate so that the joint plate can move.

[0003]

In the conventional passage joint device, when the left and right buildings sway in the front-back direction, both ends of the joint plate hit the outside of the passages of the left and right buildings, and the joint plate and the outer wall are damaged. With the drawback that
If the notch is formed in order to eliminate these drawbacks, there is a drawback that a gap is generated.

The present invention has been made in view of the above-mentioned conventional drawbacks,
Even if the left and right buildings sway significantly in the front-back direction, the swaying motion can be absorbed, and it is possible to effectively prevent damage to the joint plate and the outer wall of the building, or to create a gap between the joint plate and the joint plate. An object is to provide a joint device for passages.

The above and other objects and novel features of the present invention will become more fully 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.
