Abstract

The invention discloses a flange joint structure of a hinge pin for assembled cold forming sectional steel structural connection, which belongs to the technical field of a steel structure of structural engineering. Upper sleeve flanges are welded at the upper and lower ends of a pile sleeve. The upper and lower chord members of a truss girder are welded on the pile sleeve. A web member is welded between the two chord members. The upper and lower column jackets are plugged in the pile sleeve through a pile sleeve tube. Connection between the column jackets and the sleeve is fastened by a column flange and a sleeve flange, so that the flange joint structure of the hinge pin is formed. The flange joint structure of the hinge pin connected by a beam column provided by the invention is reasonable in structure, larger in rigidity and reliable in joint connection, has larger additional bearing capacity, and meets the design requirement of ''strong joint weak rod member''. The assembled inclined supporting cold forming sectional steel structure applying the joint has enough bearing capacity and meets the requirement of normal use.

Description

technical field [0001] The invention relates to the technical field of structural engineering steel structures, in particular to a pin shaft flange node structure used for the connection of assembled cold-formed steel structures. technical background [0002] Prefabricated cold-formed steel structure buildings have the advantages of simple construction, convenient assembly and disassembly, and environmental protection. They are in line with the development direction of housing industrialization, are conducive to the development of my country's low-carbon economy and the implementation of sustainable development strategies, and have good comprehensive benefits. Among them, the mechanical characteristics of the beam-column joints have a great influence on the load-bearing performance of the steel frame. At present, the beam-column joints used in the prefabricated cold-formed steel structure mainly include welding and bolt-welding connections. Among them, the welding rigidity ...
