Fire resistant coating holding structure, method of constructing fire resistance structure and fire resistance holding member

摘要

Problem to be solved: to provide a method of constructing a refractory coating holding member and a refractory structure using the refractory coating holding member, which is capable of securely securing the refractory covering material when the refractory covering material is disposed on the through hole of the beam, and capable of obtaining good workability.The web 3A has a through hole 9 through which a pipe or the like is inserted.A beam reinforcement 11 for reinforcing the beam 3 is fixed to the through hole 9 by welding or the like.A refracting cover 5 is disposed on the inner peripheral surface of the beam reinforcement 11 and is held by the refractory coating holding member 13.The refractory coating holding member 13 has an executive and a branch portion branched at a predetermined interval to the executives.An elevator of the refractory coating holding member 13 is wound around the outer periphery of the beam reinforcing metal member 11 projecting from the beam 3 (the web 3a), and the refractory coating holding member 13 is fixed to the beam reinforcement 11.The branch portion is bent toward the inner peripheral surface of the refractory cover 5 disposed on the inner peripheral surface of the beam reinforcement 11.Diagram
