Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through the description of the drawings and specific implementation examples.

[0040] The invention relates to a reinforced aluminum alloy beam-column joint connected by ring groove rivets with high bearing capacity and high initial rotational stiffness, which can be widely used in aluminum alloy frames and even heavy-duty aluminum alloy structures.

[0041] The components included in the present invention are: aluminum alloy I-shaped beams, aluminum alloy I-shaped columns, angular stainless steel connectors used for connecting beam and column components, backing plates (aluminum alloy material or stainless steel material) and ring groove rivets. Depending on the position of the node in the frame structure, it can be applied to a T-shaped node (that is, a side column node) or a cross-shaped node (that is, a cent...

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 ...
