To provide a fixing bracket for a fireproof covering member used for a fireproof structure capable of constructing at a lower cost with satisfactory workability.SOLUTION: A securing bracket 20 is attached to a steel beam flange for fixing a fire resistive covering member 5. The securing bracket includes: a first protrusion 21 and a second protrusion 22 whose tip penetrates the fire resistive covering member 5; a first supporting portion 24 that supports the first protrusion 21 vertically; a second support portion 25 that supports the second protrusion vertically; a connecting part 26 that connects the first supporting portion 24 and the second support portion 25 therebetween; an abutting portion 27 provided to a first supporting portion 24, which abuts on one side of the flange; and a pressing portion 28 arranged to face the abutting portion 27 while biasing the same toward the other side of the flange. The connecting part 26 has a first connecting part 33 and a second connecting part 34. The first connecting part 33 is held movably with respect to the second connecting part 34.SELECTED DRAWING: Figure 4A 【課題】作業性が良好であり、安価に施工することが可能である耐火構造に用いる耐火被覆材用固定金具を提供する。【解決手段】鉄骨梁のフランジに取り付けられ、耐火被覆材を固定するための固定金具２０であって、先端が耐火被覆材５を貫通する第１突起部２１および第２突起部２２と、第１突起部２１を立設支持する第１支持部２４と、第２突起部を立設支持する第２支持部２５と、第１支持部２４と第２支持部２５との間を連結する連結部２６と、第１支持部２４に備えられフランジの一方面に当接する当接部２７と、当接部２７に対向して配置されてフランジの他方面へ向けて付勢する押圧部２８を有し、連結部２６は、第１連結部３３と第２連結部３４を備え、第１連結部３３は第２連結部３４に対して移動可能に保持される。【選択図】図４Ａ
