Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fireproof wall which covers a ceiling or floor portion on the opening side of the left and right skeletons arranged via joints in a fireproof manner.

[0002]

2. Description of the Related Art Conventionally, the joints on the ceiling or floor on the opening side of the left and right skeletons arranged via the joints are attached and covered so that the fireproof cloth has an arc shape.

[0003]

In the conventional method of covering the joints with a fireproof cloth, the joints can be used when the joints are small in size, but the joints can be sized as in a seismic isolated structure. When the value is large, the fireproof cloth becomes large, and there is a drawback that the attachment portion is damaged by the weight of the fireproof cloth and the swinging movement in the front-back direction cannot be followed.

In view of the above-mentioned conventional drawbacks, the present invention has been made.
An object of the present invention is to provide a fireproof wall that can cover fireproofly without damage even if the left and right bodies swing in different front-rear directions by following the swinging motion.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in view of the accompanying drawings. However, the drawings are only for explanation and do not limit the technical scope of the present invention.

[0006]

In order to achieve the above object, the present invention is pivotally supported on one wall surface of the ceiling or floor portion on the opening side of the left and right skeletons arranged via joints,
A refractory support mechanism that is attached to the guide rail on the other wall so as to be slidable in the front-rear direction, and has a central portion protruding in a mountain or valley shape pivotally supported, and is fixed to this refractory support mechanism, and both end portions are fixed. Forms a fire resistant wall with one wall surface and the other wall surface and a fire resistant material that covers the joint portion of the ceiling or floor portion that is attached so as to follow the movement of the fire resistant cloth support tool.
