Abstract

The invention discloses a concrete filled steel tube column-H-shaped steel beam-steel support-pi-shaped connecting piece combined type side column bottom joint and a manufacturing method. The joint ismainly composed of a square steel tube recycled concrete column, an H-shaped steel beam, pi-shaped connecting pieces, web connecting plates, high-strength bolts, steel supports, stool steel bars anda prefabricated recycled concrete local floor slab. Compared with the prior art, the beam-column-support connecting joint is simple in structure, convenient to construct and clear in force transmission path, and has two seismic defense lines. The beam-column joint and the steel support are creatively assembled through the pi-shaped connecting pieces, the assembled floor slab is partially connectedwith the joint into a whole through the stool steel bars, the bending resistance, the pressure resistance and the stability of the joint are enhanced, and the reliability of connection between the steel support and the pi-shaped connecting pieces is guaranteed. The beam-column-support-floor slab of the joint is firm in connection, high in integrity and excellent in anti-seismic property, and keytechnical support is provided for engineering design of a light steel composite structure of an assembly type green house.

Description

technical field [0001] The invention relates to a joint at the bottom of a side column of a composite steel pipe concrete column-H-shaped steel beam-steel support-π-shaped connector and a method thereof, belonging to the technical field of structural engineering. Background technique [0002] With the continuous development of housing construction in our country, the research and development of prefabricated anti-seismic and energy-saving green housing buildings has become a major demand for national construction. The prefabricated light-steel composite structure with energy saving, environmental protection, simple construction and good seismic performance adapts to the mainstream development direction of the current residential building system. The focus of realizing the engineering application of the prefabricated light-steel composite structure is to develop new light-steel frames and light-steel truss beam-to-column connections Nodes and corresponding fabricated componen...
