Title:
BEAM-COLUMN JOINT OF CONCRETE PRECAST COLUMN AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/160387
Kind Code:
A1
Abstract:
A beam-column joint of a concrete precast column and a construction method therefor. The method comprises: acquiring a hose clamp (13), pegs (131) being provided on an inner side surface of the hose clamp (13); welding an annular reinforcing plate (14) in the hose clamp (13); arranging longitudinal ribs (4) and stirrups that bundle the longitudinal ribs (4); pouring an upper column (11) of a precast column and a lower column (12) of the precast column by using annular reinforcing plates (14) in two hose clamps (13) as boundary formworks, respectively; welding the hose clamp (13) provided with the upper column (11) of the precast column to the hose clamp (13) provided with the lower column (12) of the precast column; and providing a horizontal beam at a hose clamp (13) to connect the horizontal beam to the hose clamp (13). The hose clamps (13) and the annular reinforcing plates (14) ensure that the precast column has sufficient strength and rigidity at a beam-column joint, and ensure the safety and stability of the beam-column joint. By welding each hose clamp (13) to connect the upper column (11) of the precast column and the lower column (12) of the precast column, the connection strength is high, construction welding is easy, and the efficiency of construction is improved. The hose clamps (13) are used to connect the precast column and a horizontal beam, thus the means of connection is simple and the connection strength at the beam-column joint is ensured, the difficulty of construction is reduced, and the efficiency of construction is improved.
