Description

  The present invention relates to a floor joint device for covering joint portions of floor portions of left and right buildings such as seismic isolation buildings provided via joint portions.

Conventionally, in a seismic isolation building, etc., where the amount of movement cannot be set in a range smaller than twice the horizontal dimension of the joint, only joint plates that are less than twice the horizontal dimension of the joint are available. There is a drawback that it cannot be installed, and the dimension of the joint portion in the left-right direction and the amount of movement beyond that cannot be set.
nothing special.

  In view of the above-described conventional drawbacks, the present invention is more than the horizontal dimension of the joint part even in the field where the movement amount can be set only within a range smaller than twice the lateral dimension of the joint part. An object of the present invention is to provide a floor joint device capable of setting the amount of expansion and contraction movement.

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.

  In order to achieve the above object, according to the present invention, a rear end portion is attached to a joint on the joint portion side of one building of the left and right buildings provided via the joint portion, and a tip portion is a joint portion of the other building. A joint plate that is slidable on the floor surface of the side and is approximately twice as long as the dimension of the joint in the left-right direction, and is attached to the floor frame on the joint portion side of the other building. It protrudes into the joint part from the floor housing on the part side, and when the joint part becomes narrow due to an earthquake or the like, it is pressed and contracted by the joint on the joint part side of the one building, and the floor with the joint plate supporter that supports the joint plate This constitutes a joint device.

  As is clear from the above description, the present invention has the following effects.

(1) The rear end portion is attached to the joint on the joint portion side of one building, and the tip portion can slide on the floor surface on the joint portion side of the other building. A joint plate having a double length and the floor frame on the joint part side of the other building is normally projected into the joint part from the floor part on the joint part side, and when the joint part becomes narrow due to an earthquake or the like, the one side The joint is supported by the joint plate supporter that supports the joint plate and is contracted by being pressed by the joint on the joint part side of the building. When the joint part is widened by shaking, the tip part of the joint plate can be supported by the joint plate support tool that is attached to the floor frame on the joint part side of the other building and always projects to the joint part.
Further, when the joint portion is narrowed so that the dimension in the left-right direction is eliminated, the joint plate support can be contracted by being pressed against the floor housing of the other building by the housing of one building.
Therefore, contraction by the dimension in the horizontal direction of the joint portion can be made possible.

(2) According to (1), a joint plate that is less than twice the horizontal dimension of the joint part even at a site where the amount of movement can be set only in a range smaller than twice the lateral dimension of the joint part. , Even if the joint is widened or narrowed by the same dimension as the horizontal dimension of the joint, there is no gap in the joint and the joint plate can automatically return to its original state. The state can absorb the shaking motion.

(3) According to the above (1), it is only necessary to provide a joint plate support, so that the structure is simple and can be implemented easily.

(4) In claim 2, the same effects as in the above (1) to (3) can be obtained.
