To provide a fireproof member which makes it possible to offer a fireproof structure having excellent workability and stable quality.SOLUTION: A fireproof member 1 mainly composed of a first foam 3, a thermal expansion member 7, a second foam 9, a covering 11, and a metal fitting 21. The first foam 3, the thermal expansion member 7, and the second foam 9 are collectively covered with the covering 11. The metal fitting 21 has an insertion portion 23 and a locking portion 25 that is bent at a substantially right angle to the insertion portion 23. The first foam 3, the thermal expansion member 7, and the second foam 9 are covered and sealed with the covering 11, and the insertion portion 23 of the metal fitting 21 is pierced into the covering 11, so that the metal fitting 21 can be fixed to the fireproof member 1. The locking portion 25, which is bent at a substantially right angle to the insertion portion 23, is exposed on one side surface of the fireproof member 1. Further, the locking portion 25 exposed on one side surface side of the fireproof member 1 projects toward the side of the second foam 9 in the stacking direction of each member.SELECTED DRAWING: Figure 3 【課題】 施工性に優れ、安定した品質の耐火構造を得ることが可能な耐火部材等を提供する。【解決手段】 耐火部材１は、主に第１発泡体３、熱膨張部材７、第２発泡体９、被覆体１１、金具２１等から構成される。第１発泡体３、熱膨張部材７及び第２発泡体９は、被覆体１１によって一括して被覆される。金具２１は、挿入部２３と、挿入部２３に対してほぼ直角に曲げられた係止部２５とを有する。被覆体１１によって、第１発泡体３、熱膨張部材７及び第２発泡体９を被覆して封止した後、金具２１の挿入部２３を被覆体１１に突き刺して、金具２１を耐火部材１に対して固定することができる。挿入部２３に対してほぼ直角に折り曲げられた係止部２５は、耐火部材１の一方の側面に露出する。また、耐火部材１の一方の側面側に露出する係止部２５は、各部材の積層方向であって、第２発泡体９側に向けて突出する。【選択図】図３
