Title:
PREFABRICATED ASSEMBLY-TYPE FRAME, PREFABRICATED ASSEMBLY-TYPE BEAM-COLUMN JOINT AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/160386
Kind Code:
A1
Abstract:
A prefabricated assembly-type frame, a prefabricated assembly-type beam-column joint and a construction method therefor. The construction method for a prefabricated assembly-type beam-column joint comprises: arranging longitudinal bars and binding or welding spiral stirrups outside the longitudinal bars to form a steel reinforcement cage; sleeving a hooping plate outside the steel reinforcement cage, and connecting the steel reinforcement cage to the hooping plate; mounting a formwork and pouring concrete, and forming an upper prefabricated column and a lower prefabricated column by a centrifugation method; welding and connecting the hooping plate of the upper prefabricated column and the hooping plate of the lower prefabricated column; welding studs or corbels on the outer side surface of the hooping plate of the upper prefabricated column and the outer side surface of the hooping plate of the lower prefabricated column; and connecting a beam to the prefabricated column by means of the studs or corbels. The longitudinal bars and the spiral stirrups ensure the stiffness and strength of the prefabricated columns; the efficiency of production by the centrifugation method is high; a prefabricated column factory performs prefabricated production, the assembly of the prefabricated columns and the assembly of the prefabricated columns and the beam are performed on site, working procedures are few, the construction difficulty is low, and the construction efficiency is high; the beam is connected to the prefabricated columns by means of the studs or corbels, the connection strength at a joint is high, and the welding structure is simple and convenient for construction.
