Assembly type steel structure beam and column joint connecting device and assembling method thereof

Abstract

The invention discloses an assembly type steel structure beam and column joint connecting device and belongs to the field of assembly type steel structure buildings. The device comprises an outer sleeve, a beam connecting part, connecting angle iron, stiffening ribs and bolts. The bottom end of an upper pillar is connected to the upper end of the outer sleeve in an inserted manner, and the top endof a lower pillar is connected to the lower end of the outer sleeve in an inserted manner. An upper bearing table and a lower bearing table is arranged at the upper end and the lower end of the outersleeve correspondingly, a first ring plate in bolt connection with the upper bearing table is arranged on the upper pillar, and a second ring plate in bolt connection with the lower bearing table isarranged on the lower pillar. At least one beam connecting part is connected to the side wall of the outer sleeve, and the beam connecting part is in bolt connection with the outer sleeve through theconnecting angle iron. The assembly type steel structure beam column joint connecting device has the beneficial effects that mounting and demounting are convenient, the bearing force is large, and thedevice can be suitable for connecting of multiple sizes of beams and columns.

Description

technical field [0001] The invention relates to an assembled steel structure beam-column joint connection device and an assembly method thereof, belonging to the field of assembled steel structure buildings. Background technique [0002] Compared with traditional construction methods, prefabricated buildings are first of all faster to build, and the efficiency of factory flow is much higher than the speed of on-site construction by workers; standardized production can improve the safety level of assembly and construction; affected by climate conditions The impact is relatively small, the man-hour is less and the on-site pouring and other operations are reduced, and the environmental protection does not disturb the residents. [0003] In the design of prefabricated steel structures, the beam-column connection node is an important part of the design, and the structural form of the node will have an important impact on the strength, stiffness, and stress and deformation of the ...

AI Technical Summary

Problems solved by technology

[0004] In the past, in the prefabricated steel structure, the beam-column joints were mainly connected by welding and bolts, but welding is a thermal processing process, which requires high material requirements and high technical level requirements for workers. The welding procedures are strict and the quality inspection workload is heavy. It can work normally under dynamic load and ultra-low temperature; when the precision of the bolt connection is low, it is not suitable for shearing, and when the precision of the bolt is high, it is difficult to process and install
