Junction manner null of beam bracket equipped precast concrete pole and beam steel-frame equipped precast concrete earthquake-proof

摘要

PURPOSE: To simplify joining work by previously buriedly providing the end of an earthquake resisting wall with a beam-flange joining steel plate, and connecting the joining steel plate to the flange of the beam bracket of a column. ;CONSTITUTION: A large diameter joining reinforcement 5 for beams on upper and lower layers is joined to a beam steel frame 1, and a beam flange joining steel plate 3 is buriedly provided for forming a PC earthquake resisting wall. A with beam steel frame for the lowest floor. Next joining steel plates 3, 3 for the beam flange of the earthquake resisting wall A are joined to the beam bracket 9 of the PC column B by high strength bolts 7. In addition, the PC earthquake resisting wall A' with beam steel frame on a next layer is piled up on the earthquake resisting wall A for the lowest floor, and their beam steel frames 1 are joined through a beam to beam joining plate 6 by the high strength bolt 7. Thus the term of work can be shortened, and the cost of construction can be saved.;COPYRIGHT: (C)1994,JPO
