Concrete filled steel tube column-H-shaped steel beam-steel support-pi-shaped connecting piece combined corner column bottom joint and manufacturing method

Abstract

The invention discloses a concrete filled steel tube column-H-shaped steel beam-steel support-pi-shaped connecting piece combined corner column bottom joint and a manufacturing method. The joint is mainly composed of a light square steel tube recycled concrete column, an H-shaped steel beam, pi-shaped connecting pieces, web connecting plates, high-strength bolts, steel supports, cross-shaped benchtie bars and prefabricated recycled concrete local floor slabs. Compared with the prior art, the beam-column-support connecting joint is simple in structure, convenient to construct and low in cost.Meanwhile, the joint is clear in force transmission path and has two earthquake-proof defense lines. The beam-column joint and the steel supports are creatively assembled through the pi-shaped connecting pieces, the assembly type floor slabs are integrally tied to adjacent joint areas of the corner columns and local floor slabs through the cross-shaped bench tie bars at the positions of the cornercolumns, and the bending resistance, the pressure resistance and the stability of the assembly type floor slabs are enhanced. The joint is high in integrity and excellent in anti-seismic property, and key technical support is provided for engineering design of the light steel composite structure of the fabricated green house.

Description

technical field [0001] The invention relates to a joint at the bottom of a corner column combined with a concrete filled steel tube 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] Prefabricated buildings have the advantages of short construction period, high degree of standardization, green environmental protection, pollution-free, low cost, etc., which meet the strategic needs and mainstream trends of the development of my country's construction industry. The assembly and industrialization of residential buildings is an important support for the modernization of the construction industry. The industrialization development of prefabricated civil buildings, especially low-rise and multi-storey residential buildings in villages and towns is very important. It is an inevitable trend in the development of the construction industry to develop prefabricated ...
