A reinforced prefabricated recycled concrete beam-column joint

Abstract

The invention discloses a reinforced prefabricated recycled concrete beam-column joint, comprising a main shell, two connecting columns are welded at the top and bottom ends of the main shell, and longitudinal beam rods are integrally formed on the inner side walls of the connecting columns , the connecting column is inserted with the longitudinal beam through the longitudinal beam rod, the front surface, the rear surface and the two sides of the connecting column are welded with four fixing plates, and the inner side of the fixing plate is connected to the main shell through two first bolts The front surface, rear surface and both sides of the main casing are integrally formed with four beam bars, and sixteen anti-shear fixing groups are fixedly connected to the outer surface of the beam bars. The anti-shear fixing group is threadedly connected with a cross beam; through the cooperation between the partition plate and the fixing plate to the main shell and the connecting column, the bolt group cooperates with the series wire and the stop washer to eliminate the occurrence of the bolt group under the action of time. The relative sliding phenomenon between the tooth lines can avoid the occurrence of dangerous accidents.

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 joint. Background technique [0002] The beam-column joint refers to the intersection of the frame structure beam and the column in the construction field. A cross-connector is usually used to fix the beam and the longitudinal beam at this position. This device is the beam-column joint. Prefabricated recycled concrete beams and columns are widely used in residences, schools, and office buildings. Prestressed concrete beams or slabs are also applied according to needs, so as to be suitable for larger spans; such beam-column joints are often used for large spans. In public buildings, multi-storey industrial plants and some special-purpose buildings, such as theaters, shopping malls, gymnasiums, railway stations, exhibition halls, shipyards, hangars, parking lots, light industrial workshops, etc. ...

AI Technical Summary

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 column compared with the frame structure

Beam-column joints designed according to construction standards may cause changes in shear stress due to such uncertain factors, and internal fatigue cracks may even increase in area under the action of time, resulting in shortened building life and increased risk factors
