Abstract

The invention discloses a concrete filled steel tube column-H-shaped steel beam-steel support-pi-shaped connecting piece combined type middle column middle joint and a manufacturing method. The connecting structure comprises light square steel tube recycled concrete columns, H-shaped steel beams, pi-shaped connecting pieces, web connecting plates, high-strength bolts, steel supports, I-shaped bench steel tie bars, plate column steel tie bars and prefabricated recycled concrete local floors. Novel assembly type joint connecting and reinforcing structures such as pi-shaped connecting pieces andI-shaped stool steel tie bars are creatively provided, the overall assembly difficulty of beam-column-support-floor slabs in a joint area is effectively lowered, and the integrity, bearing capacity and deformation capacity of the joint are remarkably improved. Compared with the prior art, the joint has the advantages that the structure is simple, construction is convenient, the force transmissionpath is clear, and two anti-seismic defense lines are provided. 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 in the middle of a central column suitable for a combined type of concrete filled steel tube column-H-shaped steel beam-steel support-π-shaped connector and a method, and belongs to the technical field of structural engineering. Background technique [0002] With the development of construction industry technology, housing industrialization is the development trend of the construction industry in the future. The fabricated steel structure is a major change in the way of construction, and the modules processed by the factory are spliced ​​together by bolts on site. Compared with traditional residential structures, prefabricated steel structure houses have the advantages of high integration, superior seismic performance, environmental protection and energy saving, short construction period, and high product quality. From the perspective of resource conservation, green development, and circular economy, prefabricated stee...
