PROBLEM TO BE SOLVED: To provide a fire-resistant structure with excellent strength. SOLUTION: In this fire-resistant structure A, a surface of a concrete structure 1 is coated with a fire-resistive covering layer 2 which is constituted by solidifying monolithic refractories. A net-like body 3, which is formed of heat-resistant fibers impregnated with a thermoplastic resin and which has a through-hole, is arranged in the fire-resistive covering layer 2. The monolithic refractories 21 and 22 on both the sides of the net-like body 3 are connected and integrated together through the through-hole 31. The fire-resistive covering layer 2, which is integrated as a whole without being separated by the net-like body 3, has the excellent strength by having the net-like body 3 arranged inside. Thus, the durable period of the fire-resistant structure A is long. COPYRIGHT: (C)2010,JPO&INPIT
