Connection node construction of concrete-filled square steel tube column and rectangular section steel beam

Abstract

The invention discloses a connection node construction of a concrete-filled square steel tube column and a rectangular section steel beam. The connection node construction is formed by the concrete-filled square steel tube column, the rectangular section steel beam, a right-angle connecting plate, a T-shaped triangle rib plate, a high-strength bolt, and a toggle pin on the top face of the steel beam. The connection node construction is simple, and the stress is clear. The amount of the steel for the connection node construction is less, and the connection node construction is only installed at one side of the column provided with the beam, so the composite cost is lower. The design of the beam column connection node is the ductile failure mode that the beam end is damaged by the tension, the obvious symptom and the duration time are existent before the damage, and the whole structure cannot be collapsed by the local failure. The connection of the steel beam and the concrete-filled steel tube column is firm, the integrality is good, the node rigidity is large, the assembly is simple and the construction period is short. New building rubbishes are not generated, and the requirements of housing industrialization and environmental protection are satisfied. The connection node construction is a novel node connection mode suitable for the connection of the current lower-layer and multi-layer light steel frame housing construction beam columns.

Description

technical field [0001] The invention relates to a connection node structure and method of a square steel pipe concrete column and a rectangular cross-section steel beam, and belongs to the technical field of construction engineering. Background technique [0002] In recent years, with the increase of my country's steel production and people's increasing requirements for environmental protection, energy saving, and housing industrialization, the prefabricated light steel structure with low pollution, short construction period, and good thermal insulation and energy saving effects has attracted great attention from the government and research institutions. More and more scholars have carried out in-depth research on this structure. In prefabricated light steel structures, the traditional steel frames are mostly steel columns with I-shaped cross-sections. Because the moment of inertia of the two main axes of the I-shaped cross-section is quite different, the lateral load-bearing...
