step four, installing a steel bar test piece manufacturing device: a suspended steel bar placing batten (28) is welded and fixed on a frame support (26), a replaceable steel bar support cavity (29) is fixed on the suspended steel bar placing batten (28) through a support cavity fixing screw rod (30), a support hole middle connecting plate (31) and a support hole top plate (32) are fixed on the frame support (26), and an upper cover plate (36) is connected through a replaceable steel bar fixing vertical cylinder (33), so that the multi-diameter steel bar test piece manufacturing device is formed;
step five, fixing the connecting sleeve: vertical dowel bars (48) and lower cast-in-place wall main bars (46) are connected through connecting sleeves (47), and integral groined fixing bar frames (49), guide short bar grooves (50) and prefabricated block jacking supports (51) with the same marks are arranged at the positions of the connecting sleeves (47);
step six, hoisting the prefabricated bay window: a chain block (75) and a safety rope (76) are arranged on the modular hanging beam (74) to connect with the lifting lug (60); the temporary pull rod (78) and the temporary pull rope (79) are combined and temporarily fixed between the bay window temporary channel steel fixing frame (77) and the inner side fixing frame (80) through a framework fixing stud (81).
