REINFORCING STRUCTURE OF BUILDING

PROBLEM TO BE SOLVED: To efficiently perform work by manpower work even in work in a limited space by arranging a beam material in close vicinity to a slab under surface of a structure, connecting diagonal members to this beam material, and reinforcing the building by charging a clearance material in clearance between a slab and the beam material. SOLUTION: This reinforcing structure of a building is composed of a beam material 2 arranged in close vicinity to a slab 1 under surface of an existing building, diagonal members 4 for connecting underground beams 3 and the beam material 2 for supporting a slab 1 and a clearance material 5 loaded in clearance between the slab 1 and the beam material 2. Brackets 7a, 7b are preinstalled on the existing underground beams 3, and fixing materials 6b for previously fixing the diagonal members 4 are welded to the brackets 7b. After placing and fixing the beam material 2 between the brackets 7a, 7a, the diagonal members 4 are installed between fixing materials 6a welded to an under surface flange 10 of the beam material 2 and the fixing materials 6b installed on the brackets 7b of the underground beams 3, and the clearance material 5 is loaded in clearance between a bottom surface of the slab 1 and an upper surface flange 10 of the beam material 2.
