Description

The present invention relates to a floor joint device that closes joints between building blocks provided through joints.

Conventionally, floor joint devices for closing joints formed in places where the slide width of the joint plate cannot be secured are sufficient, such as near the boundary with other people's premises, public roads, etc., or in places where walls are close together. One of the floor structures is formed so that the width dimension is approximately the same as the width of the joints of the left and right floor structures provided through the boundary line, and the upper surface of this one floor structure is a joint plate support mechanism having an operating rod that is fixed and attached so as to always protrude from a plurality of support tubes to the joint portion by the width dimension of the joint portion; and an upper surface of the support tube of the joint plate support mechanism. a fixed joint plate fixed to the support tube or the one floor framework and formed on an inclined surface with a lower end on the joint side protruding toward the joint, and the one floor framework and a protrusion located through the joint part, and whose upper surface position is approximately the same as the upper surface position of the fixed joint plate; a joint plate whose end portion is movable upward and whose tip portion is supported by the joint plate support mechanism to cover the joint portion; and a stopper that restricts a protruding position of an operating rod of the joint plate support mechanism. , a support rod that protrudes downward at the tip of the operating rod of the joint plate support mechanism is slidably supported, and is fixed to the joint side of the one floor structure that enters the lower part of the protrusion of the other floor structure. "A floor joint device characterized in that it consists of a support body made of a metal material," is known (Patent Document 1).

However, in such a floor joint device, the parts and members (supporting bodies) that support the support rods are the same skeleton as the frame to which the support rods are fixed, so it is difficult to absorb swinging movements in the front, back, left, and right directions. However, if the part or member (supporting body) that supports the support rod is a different frame from the frame to which the support rod is fixed, there is a drawback that it cannot slide smoothly in the front-back direction.
