[0027]

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

(1) One base rail integrally formed with a joint plate support fixed in a recess formed in the floor of one building on the joint side of the left and right buildings, and the one base rail The other base rail formed with a front-rear guide rail fixed in a recess formed in the floor of the other building corresponding to the base rail, and slidably moved via the guide rail and the slide member of the other base rail. One end portion is attached to the joint plate, and a portion near the other end is supported by the joint plate supporting portion of the one base rail so as to be slidable in the left-right direction, and an upper portion of the other end of the joint plate. One cover plate attached to the one base rail so as to cover, and the other cover plate attached to the other base rail so as to cover the upper part of one end of the joint plate. Therefore, even if the left and right buildings swing back and forth and left and right due to an earthquake, etc., one end of the joint plate and the other base rail attached to the other building slide in the front and rear direction and move in the front and rear direction. Absorb the shaking, the other end of the joint plate and one of the base rails attached to one building slide in the left and right direction,
Swing in the left-right direction can be absorbed. Therefore,
The swinging motion in the front, rear, left and right directions can be absorbed and the damage can be efficiently prevented.

(2) According to the above (1), one end and the other end of the joint plate absorb the swinging motion in the front-rear direction and the left-right direction, so that the joint plate can be always positioned at a predetermined position. It is possible to reliably prevent the joint plate from being displaced and becoming unsightly.

(3) According to the above (1), the sliding portion of the joint plate is divided into the front-rear direction and the left-right direction, so that it can be smoothly slid, and reliable sliding movement and improvement in durability can be achieved. Can be planned.

(4) According to the above (1), the joint plate supporting portion is integrally formed on one of the base rails.
The joint plate support can be attached simply by fixing one base rail in a recess formed in the floor of one building. Therefore, the joint plate supporting portion can be easily attached as compared with a conventional joint plate supporting portion formed separately. In addition, since the joint plate support is integrally formed with one of the base rails, the joint plate support can be prevented from falling off unless one of the base rails is detached. Therefore, it is not necessary to check whether or not the joint plate is loosened or detached due to vibration or the like by removing the joint plate as in the related art, and the joint plate supporting portion can be used safely.

(5) Claims 2 and 3 also correspond to (1) to (4).
The same effect can be obtained.
