Japanese Patent No. 36060310

    In view of the above-described conventional drawbacks, the present invention has an opening of a building such as an elevator shaft, a stair shaft or a building, or a floor frame of a ground corresponding to an opening of the building or the ground, and has only twice or less the size of the joint. An object of the present invention is to provide a floor joint device for a building that can be expanded and contracted substantially by the size of the joint portion and that can move the floor joint plate while always maintaining a square shape.

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, the present invention slides left and right on the outer wall surface at the lower position of an opening of an elevator shaft, a stair shaft, or a building such as a building provided via a building or ground frame and joints. One end is fixed to the slide moving rod attached movably, and the joint portion can be covered with a joint plate having a size less than twice that of the joint portion when the building is moved in the front-rear direction. The floor joint device of a building is composed of a floor joint device body that always moves in a square state.

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

(1) Slide movement attached to the outer wall surface of the lower position of the opening of a building such as an elevator shaft, stair shaft or building provided via a building or ground frame and joints so as to be slidable in the left-right direction. A floor that is fixed in a square shape and can be covered with a joint plate having a size that is less than twice the size of the joint when the building is moved in the front-rear direction. Since the floor joint device main body is always moved in a square shape, it can be used safely and can be reliably prevented from generating a gap during movement. .

(2) According to the above (1), the building or the ground frame of the site corresponding to the outer wall surface of the opening of the building can be installed and used even if it is less than twice the size of the joint.
For this reason, the building can be easily installed even in a building having such a dimension or a floor frame part of the ground.

(3) According to the above (1), since it can be installed only on the floor joint device at the lower part of the outer wall surface of the opening of the building, compared with the conventional one installed with the joint device on both side walls that can be expanded and contracted, It can be installed easily.
