FIREPROOF COATING STRUCTURE AND EXTENSIBLE FIXING MEANS USED FOR THE SAME

PROBLEM TO BE SOLVED: To provide a fireproof coating structure and an extensible fixing means used for the fireproof coating structure having excellent fire resistance by uniforming thickness during expansion and after expansion when expanding receiving the heat of a fire or the like. SOLUTION: The fireproof coating structure 10 has: an effervescent fireproof agent 1 installed on the surface 91 of a structure 90; a net-like body (a general term for a mesh, a net, a grating, or the like) 2 installed on the surface of the effervescent fireproof agent; the extensible fixing means 3 fixed to the structure 90 to penetrate the effervescent fireproof agent 1 and formed with a locking part 3k at the tip; and a fireproof coating material 4 covering the net-like body 2 and the locking part 3k of the extensible fixing means 3. The extensible fixing means 3 has a tapping screw part 3t screwed to the structure 90, and a coil part 3c with its lower end fixed to the tapping screw part 3t. A locking part 3k is formed at the upper end of the coil part 3c, and the locking part 3k is locked to the net-like body 2. COPYRIGHT: (C)2010,JPO&INPIT
