A joint plate in which a piece is formed and the other end is located at a position near the center of the other support fitting; and a stop piece attached to the one support fitting for stopping a stopper piece of the joint plate at a predetermined position. A cover plate attached to the one support bracket so as to cover an upper portion of one end of the joint plate and an upper portion of the one support bracket, and an upper portion of the other end of the joint plate. And another cover plate attached to the other support bracket so as to cover the upper part of the other support bracket so as to allow the joint plate to slide, and one side surface of the one cover plate or one support bracket. One end is pivotally supported at a portion near the joint, and the other end is abutted on one side and the top of the other support fitting,
One side joint plate covers a gap between joint plates generated when the left and right buildings swing in the front-rear direction, and one end is turned to a portion near the joint on the other side of the other cover plate or the other side of the support bracket. The other side joint plate is movably pivotally supported, the other end of which is in contact with the other side surface and the upper portion of one of the support brackets, and covers a gap between joint plates generated when the right and left buildings swing back and forth. Constitutes a joint device for floor.

[0021]

14 to 22 show different embodiments of the present invention.
Hereinafter, different embodiments of the present invention will be described. In the description of the different embodiments of the present invention, the same components as those of the first embodiment of the present invention are denoted by the same reference numerals, and duplicate description will be omitted.

The second embodiment of the present invention shown in FIGS. 14 to 16 is mainly different from the first embodiment of the present invention in that the side joint plate 9 having the same shape as the one-side joint plate 9 is used. By attaching the guide shaft 21 to the joint plate support portion 11 of the other support fitting 5 in this manner, the floor joint device 1A can be constituted by one type of side joint plate 9 The points can be reduced.

The third embodiment of the present invention shown in FIGS. 17 to 19 is mainly different from the first embodiment of the present invention in that a joint plate is provided at a position near both sides of the other support metal member 5A. Locking grooves 27, 2 that allow the contact pieces 20, 20 of the side joint plates 9, 9A to be locked with play in the support portion 11.
7, the other joint metal fitting 5A formed in this way is used, and the side joint plate 9,
By locking the contact pieces 20 and 20 of 9A, the side joint plates 9 and 9A can be held without using an urging spring.
When the rocking motion such as an earthquake stops, the joint plate 6 can be located at a predetermined position.

The fourth embodiment of the present invention shown in FIGS. 20 to 22 is mainly different from the first embodiment of the present invention in that the side joint plates 9, 9A
In the floor joint device 1C thus configured, the pivot joint pins 28, 28 are rotatably attached to the portions near both sides of the floor joint, and the same operation as that of the first embodiment of the present invention described above. The effect is obtained.

[0025]

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

(1) A pair of recesses formed on the floors at the ends of the joints of the left and right buildings built via the joints, respectively, and a pair of substantially channel-shaped members respectively fixed in the pair of recesses. And a stopper piece that is supported by the joint plate support portion on the joint portion side of the pair of support fittings and that covers the joint portion and that is locked by one joint plate support portion, and the other end portion is formed. A joint plate located at a position near the center of the other support bracket, a stop piece mounted in the one support bracket for stopping a stopper piece of the joint plate at a predetermined position, and one end of the joint plate A cover plate attached to the one support bracket so as to cover an upper part of the joint and the one support bracket, an upper part of the other end of the joint plate and an upper part of the other support bracket The other cover plate attached to the other support bracket so as to cover the sliding movement of the joint plate, and one end is located at a portion near the joint on one side of the one cover plate or one support bracket. A one-side joint plate that pivotally pivotally supports the other end and abuts one side and an upper part of the other support bracket, and covers a gap between joint plates generated when the left and right buildings swing back and forth. One end is rotatably supported at a portion near the joint on the other side of the other cover plate or the other support fitting, and the other end is in contact with the other side and upper part of the one support fitting, Since the left and right buildings are composed of joint plates on the other side that cover gaps between joint plates generated when the right and left buildings swing in the front-back direction, the joint play is performed when the left and right buildings swing in the front-back direction. A gap generated in the both side portions can be prevented by the movement of the side joint plate. Therefore, even if the left and right buildings swing in the front-rear direction, no gap is formed on both sides of the joint plate, so that the joint can be used safely.

(2) According to the above (1), when the swaying motion such as an earthquake stops, the joint plate can be automatically returned to a predetermined position by the side joint plate. Therefore, it can always be used in a normal state.

(3) According to the above (1), since the structure is simple, it can be easily installed and can be manufactured at relatively low cost.

(4) Claim 2 has the same effect as (1) to (3).
