Aluminum alloy beam-column joints connected by backing plate-reinforced ring groove rivets

Abstract

The invention relates to a base plate reinforced type ring-grooved rivet connection aluminum alloy beam-column joint. The base plate reinforced type ring-grooved rivet connection aluminum alloy beam-column joint comprises an aluminum alloy I-shaped beam, an aluminum alloy column, four angled stainless steel connecting parts, ring-grooved rivets and reinforced base plates, the four angled stainlesssteel connecting parts are arranged at the junction of the beam and the column in pairs, arranged at an upper flange and a lower flange of the beam and the two sides of a beam web plate correspondingly and all connected with column flanges, and the base plates are symmetrically arranged on the inner sides of the column flanges. The joint has the excellent performance which is owned by an ordinarybeam-column joint, for example, the joint can be quickly assembled on a construction site, the strength reduction problem of a welding joint can be solved, and the problem of electrochemical corrosion of bolt connection joints is solved, in addition, the joint has the quite high carrying capacity and the quite high initial rotation stiffness; the ring-grooved rivets serve as novel connection fasteners, can provide high pretightening force, and resist loosening and resist vibration; and through the novel joint, the mechanical performance of an aluminum alloy structure can be greatly improved,and the construction speed of the aluminum alloy structure is increased.

Description

technical field [0001] The invention belongs to the technical field of metal structures in structural engineering, and relates to an assembled and combined connection node of aluminum alloy structural parts. Background technique [0002] With the development of aluminum alloy smelting technology in China, aluminum alloy structures have gradually become a hot spot in the research and application of structural engineering. Due to the good corrosion resistance, high specific strength and easy extrusion of aluminum alloys, more than 6,000 aluminum alloy structures have been put into use worldwide, including long-span roof structures, aluminum alloy bridges, and towering structures. Wait. As the research on aluminum alloy components and the overall structure gradually matures, it will also be applied to the frame structure. [0003] The biggest problem faced by using aluminum alloy as a structural material in a frame structure is the connection between components, that is, the ...
