Concrete beam column connecting joint and temporary support mounting method

Abstract

The invention discloses a concrete beam column connecting joint and a temporary support mounting method, and belongs to the technical field of fabricated building engineering. An upper layer of prefabricated cylinders and a lower layer of prefabricated cylinders are connected through energy-consuming steel cylinders, and prefabricated cross beams are transversely connected to the side faces of the energy-consuming steel cylinders through mounting clamping pieces. H-shaped steel is arranged in a concrete beam column, the energy-consuming steel cylinders are mounted at the connecting joint, the overall stability of a column body structure is improved, meanwhile, the damping energy characteristic is eliminated, and additional reinforcement is not needed; a mounting support is connected through column body pre-planted support fixing feet, damage of manual operation to a column body during supporting is reduced, and the field work efficiency is improved while the connecting strength is guaranteed; and through the beam column flange type outer ring plate full-bolt connecting joint, welding work can be completed in a factory, component mounting is completed only by screwing bolts on a construction site, the adverse effects of the welding line quality, the welding residual stress and the like on the joint stress performance can be avoided, the ductility of the joint is improved, and the difficulty of field construction quality control is further lowered.

Description

technical field [0001] The invention belongs to the technical field of prefabricated construction engineering, and in particular relates to a concrete beam-column connection node structure containing H-shaped steel and a temporary support installation method. Background technique [0002] At present, the prefabricated composite structure belongs to the initial stage in our country. The construction method of the prefabricated composite structure building is to manufacture the main components and parts of the building in the factory, and then transport them to the site. After mechanized installation, a building that meets the predetermined functional requirements is formed. The prefabricated steel-concrete composite structure building has the advantages of good seismic performance, high construction quality, simple fabrication, high degree of industrialization, green and energy saving, etc. Nodes are the main part of the composition and stress of the structural system.

Problems solved by technology

The traditional all-welded and bolt-welded hybrid joints need to weld steel beams and steel pipe columns on site. The welding is difficult, the weld strength is low, and the stability is poor. Difficult to disassemble and install
