[0020]

As is apparent from the above description, the following effects can be obtained in the present invention.

(1) A joint plate that is open on the joint portion when the lower surface formed on both side walls on the joint portion side of one of the left and right buildings built via the joint portion is not more than the same surface as the floor surface. The moving gap and the frame on the joint side of the other building, the rear end is attached so as to communicate with the floor of the other building, and the tip end is on the floor of the joint side of the one building. The joint plate is supported, and both ends of the joint plate cover the joint plate moving gap and the inner surface of the joint plate moving gap in which both ends of the joint plate enter, and move so as not to prevent movement of the joint plate. Since it is configured with a movable cover device that can be moved, the free end portion of the joint plate can freely move within the joint plate moving gap when the left and right buildings shake due to an earthquake or the like. Therefore, shaking motion such as an earthquake can be absorbed without damaging the joint plate or the like.

(2) According to the above (1), the inner surface of the joint plate moving gap can be covered with the movable cover device so as not to prevent the joint plate from moving. Therefore, it is possible to prevent a gap from being formed between the joint plate and the wall surface, and improve the aesthetic appearance.

(3) According to the above (1), even a building having a large amount of movement such as a base-isolated building can be easily installed so as to absorb the amount of movement.

(4) Claims 2, 3, and 4 also include the above (1) to
The same effect as (3) can be obtained.
