Abstract

A prefabricated building beam-column joint structure and a construction method thereof relate to a beam-column joint and a construction method. Two to four steel beams are connected between the upper steel pipe column and the lower steel pipe column. Flat plates and flanges are respectively arranged at both ends of the joint connection seat. The two joint connection seats are respectively fixed on the lower end of the upper steel pipe column and the upper end of the lower steel pipe column. Two spherical positioning grooves are recessed on each side of the periphery, and two ball-joint lap rods are set at the steel beam connection end to be clamped between the corresponding spherical positioning grooves of the two flat plates. The edges of the two flat plates are connected and fixed by fastening bolts and nuts. The upper part of the beam is suspended and connected with the upper steel pipe column by a steel wire rope, and the energy-dissipating steel plate is diagonally braced between the lower part of the steel beam and the lower steel pipe column. A connection structure similar to a spherical hinge is adopted between the beams and columns, and the upper part is suspended by wire ropes, and the lower part is installed with energy-dissipating steel plates, which cooperate with each other to play an efficient energy-dissipating effect. The structure is stable and easy to assemble and repair damage.

Description

technical field [0001] The invention relates to a beam-column joint and a construction method, in particular to a prefabricated building beam-column joint structure and a construction method thereof, belonging to the technical field of prefabricated building construction. Background technique [0002] Prefabricated buildings adopt standardized design, factory production, and assembly construction. A large number of on-site operations in traditional construction are transferred to the factory for prefabrication. They can be assembled and installed on site after being transported to the site during construction. It has many advantages such as low pollution and greatly reducing the number of construction workers on site, which is currently recognized as the future development trend of the construction industry. [0003] However, at present, prefabricated buildings basically use bolts or welding to connect beams and columns at the beam-column joints, which is not conducive to en...
