DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint device such as a floor covering a joint between a floor surface, a wall surface or a ceiling surface of right and left buildings built through joints.

[0002]

2. Description of the Related Art A conventional joint device for floors comprises a pair of base rails attached to left and right floors on the joint side of right and left buildings built through joints, and a pair of base rails on the pair of base rails. The joint plate includes a joint plate that is mounted so as to be slidably supported at a portion closer thereto, and a pair of cover plates that are attached to the pair of base rails so as to cover both side portions of the joint plate.

[0003]

The conventional joint device for floors can absorb small left and right swaying movements caused by an earthquake or the like, and can provide absorption by providing gaps between both ends of the joint plate and the wall surface. However, in the case of a seismically isolated building, the joints are set to a large size due to the large shaking of the building, so the large shaking must be absorbed, but there is a disadvantage that it cannot be sufficiently absorbed. . In addition, the swinging motion of the seismically isolated building does not move in the front-rear and left-right directions, but also causes the swinging motion to rotate. Therefore, such a shaking motion cannot be absorbed and there is a disadvantage that the building is damaged.

The present invention has been made in view of the above-mentioned conventional drawbacks,
To provide a joint device such as a floor capable of absorbing even a large swing motion to prevent damage, and smoothly sliding even in a swing motion in which a building rotates, thereby absorbing the swing motion. It is an object.

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

[0006]

In order to achieve the above object, the present invention provides a pair of base rails respectively fixed to floors near joints of left and right buildings built via joints, A joint plate attached to the part except for both ends of the pair of base rails so that the parts near both sides are slid and supported even when the left and right buildings swing,
A center maintaining mechanism in which both ends supporting the joint plate to be always positioned at the center are attached to the pair of base rails or the frame on the joint part side of the left and right buildings,
A pair of arc-shaped or mountain-shaped abutting portions that are slidably overlapped with both ends of the joint plate, respectively, and that are slidably supported on both sides of the pair of base rails. An end joint plate, a biasing mechanism attached to a central portion near an end of the joint plate for urging the pair of end joint plates to always project outward, and the pair of end joints. Two pairs of auxiliary joint plates mounted so as to always protrude outward by springs from both outer end portions of the joint plate, and the pair of auxiliary joint plates so as to cover upper portions of both side portions of the joint plate and the pair of end joint plates. A joint device such as a floor is constituted by a pair of cover plates attached to a pair of base rails.
