Reinforced prefabricated recycled concrete beam-column joint

Abstract

The invention discloses a reinforced prefabricated recycled concrete beam-column joint. The reinforced prefabricated recycled concrete beam-column joint comprises a main shell, two connecting columnsare welded to the top end and the bottom end of the main shell, longitudinal beam rods are integrally formed on the inner side walls of the connecting columns, longitudinal beams are inserted into theconnecting columns through the longitudinal beam rods, four fixing plates are welded to the front surfaces, the rear surfaces and the two side faces of the connecting columns, the inner sides of thefixing plates are in threaded connection with the main shell through two first bolts, four cross beam rods are integrally formed on the front surface, the rear surface and the two side faces of the main shell, sixteen anti-shearing fixing sets are fixedly connected to the outer surfaces of the cross beam rods, and the cross beam rods are in threaded connection with cross beams through the anti-shearing fixing set. Through cooperation of a partition plate and the fixing plates on the main shell and the connecting columns, a bolt set is matched with a locking gasket through a series connection steel wire, the relative sliding phenomenon between threads of the bolt set under the action of time is eliminated, and dangerous accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of building support structure devices, in particular to a reinforced prefabricated recycled concrete beam-column node. Background technique [0002] Beam-column joints refer to the intersection of frame structure beams and columns in the field of construction. At this position, a cross-connector is usually used to fix the beams and longitudinal beams. This device is called beam-column joints. The prefabricated recycled concrete beams and columns used in conjunction with them are widely used in residential buildings, schools, and office buildings, and prestressing of concrete beams or slabs is also required to apply to larger spans; and such beam-column joints are often used in large spans In public buildings, multi-storey industrial plants and some special-purpose buildings, such as theaters, shopping malls, stadiums, railway stations, exhibition halls, shipyards, hangars, parking lots, light industry worksh...

Problems solved by technology

[0003] Due to the particularity of its working environment, its beams and columns often have to be pre-installed with other heavy equipment after the design is completed, which leads to a larger mass of the beam, and a corresponding increase in the shear force at the intersection of the beam and the colum
