PURPOSE: To increase workability by using a bracket installed beforehand when a girder steel frame is manufactured, commonly for a scaffolding hanger, form timbering fixture, and exterior wall PC panel supporting material fixture.
CONSTITUTION: A supporting hardware 2 in which pin holes 6 and 7 are located on its upper and lower two rows, respectively, is provided, and installed projectedly on the lower surface of a lower flange 1a of a girder steel frame 1. Next, a scaffolding 9 is fitted to the holes 7 through a hanging hardware 10, and the frame 1 is placed and fixed to a specified erection position for a building. Then a timbering 11 is installed in the holes 6 and, after a form 4 is assembled through it, concrete 3 is deposited and cured. After the form 4 is disassembled, an exterior wall PC panel supporting material 13 is connected and fixed to a hold 6 and a bracket 15 provided on the girder 1 beforehand. Also an exterior wall PC panel 12 is installed on the supporting material 13 using angles 18 and 19, etc. Thus labor can be saved for site temporary work, work period can be shortened, and safety and quality can be increased.
