Abstract

PROBLEM TO BE SOLVED: To make it possible to eliminate an offset area in a floor surface and a loosen area and enhance workability an inhibit the deflection of a tie beam. SOLUTION: The tip of a plurality of tie beams 6 which connect a building main body 4 to a front beam which is laid out as opposed to this building main body 4, is projected from the front beam to the outdoor side so that the tie beams 6 may be loaded on the top of the front beam 7 and fixed. Then, a handrail wall 15 is supported on the tip of the tie beams 6. Since the tie beams 6 are loaded on and fixed with the top of the front beam 7 as described above, a mounting level of the tie beams 6 is determined by the top of the front beam 7, which makes it possible to eliminate an offset area in a floor 11 and a loosen area as well. It is also possible to inhibit the deflection of the tie beams 6 attributable to floor load with the reaction force which uses the front beam 7 produced by the load of the handrail wall 15 as a fulcrum since the handrail wall 15 is supported on the tip of the tie beams 6 by projecting the tip of the tie beams 6 from the front beam 7 to the outdoor side.
