BACKGROUND ART Generally, in a high-rise building, it is required to attach a fireproof coating material to a metal frame of the building due to legal regulations. Such a fireproof coating material has a role of protecting the frame from heat generated in a fire, and hard rock wool or the like is used as the material thereof.

Conventionally, a plate-shaped fireproof coating material has been attached to a frame as follows. First, a bolt mounting hole is drilled in the skeleton, the bolt is inserted into the mounting hole from the inside of the skeleton, and the screw part of the bolt is welded in a state of protruding to the outer peripheral surface side of the skeleton. The fireproof coating material is supported by the frame by inserting the bolt holes formed in the material. Then, the nut is fastened to the screw portion protruding from the surface of the fireproof covering material to attach the fireproof covering material to the frame.
Alternatively, without forming a mounting hole in the skeleton, directly weld the screw part of the bolt at a predetermined position on the outer peripheral surface of the skeleton, and insert the fireproof covering material into this screw part by inserting the bolt hole formed with the fireproof covering material. The frame was supported, and the nut was tightened to the screw portion protruding from the surface of the fireproof coating material to attach the fireproof coating material to the frame. Alternatively, the screw is penetrated through the fireproof coating material, and at the same time, the screw is driven into the pillar to attach the fireproof coating material to the frame.

[0004]

However, in the first prior art, when the mounting holes of the bolts drilled in the frame are misaligned, or in the second prior art, the threaded portion of the bolt is used. When the welding position of is deviated,
There is a drawback in that the refractory covering cannot be accurately attached to the frame at a predetermined position. Moreover, in order to secure the positional accuracy of the fixture, it takes a long time to perform the drilling work and the welding work, and there is a problem that the work of attaching the fireproof coating cannot be performed efficiently. On the other hand, the third conventional technique has a drawback in that the screw driving operation is heavy labor and the working efficiency is poor.

The present invention has been made in view of the above circumstances, and when the fire-resistant coating material is attached to the frame of a building, the fire-resistant coating material can be attached to the frame so that the fire-resistant coating material is in a predetermined position. It is an object of the present invention to provide a fixture for a fireproof coating material that can be easily and quickly attached.
