Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cross joint floor joint device.
[0002]
[Prior art]
Conventionally, a joint device for a cross passage has a front end located at a substantially central portion of a base rail fixed by forming a recess in a floor frame near a joint of one of the cross passages, and a rear end thereof. A joint plate fixed to the floor frame near the joint of the other crossing passage, and fixed to the base rail so as to cover the tip of the joint plate and the upper part of the base rail. And a cover plate.
[0003]
[Problems to be solved by the invention]
The conventional cross-joint joint device can absorb different swinging motions in the front and rear and left and right directions due to an earthquake or the like, but if it swings in the front and rear direction, the joint plate becomes integrated with the other building. Since it moves in the front-rear direction, a gap without joint plates is formed at the front and rear ends of one of the buildings, which is disadvantageous in that it is dangerous.
[0004]
In view of the above-mentioned conventional disadvantages, the present invention can absorb the swinging motion even if the left and right buildings swing in different front and rear and left and right directions, and ensure that there is a gap at the joint portion and it is dangerous. It is an object of the present invention to provide a cross joint floor joint device which can be prevented and can be used safely by rotating the whole in different front and rear directions.
[0005]
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 merely for explanation and do not limit the technical scope of the present invention.
