PROBLEM TO BE SOLVED: To easily perform a fireproofing coating by cutting off a fire spread path at the engagement position of an H-steel beam and a fireproofing wall, and to suppress the cost required for constructing a building. SOLUTION: This fireproofing coated backing member includes a rectangular plate 2 fitted to a gap part 40 and a hook-shaped body 3 projecting from one corner of the rectangular plate 2. The rectangular plate 2 has both side-surfaces 21 of a shape similar to the cross sectional shape of the gap part 40 in the lateral direction of a flange 41, and is fitted so that the both side-surfaces are positioned vertically so as to be parallel to the lateral direction of the flange 41 in the gap part 40. The edge surfaces 41a of the flange 41 are fitted between the vertically installed rectangular plate and the hook-shaped body. The fireproofing coated backing member 1 thus obtained is detachably mounted at the engagement position, cuts off the fire spread path of the gap part 40, and functions also as a backing material for fireproofing coating.
