Aluminum alloy beam-column joints connected by channel steel reinforced ring groove rivets

Abstract

The invention relates to an aluminum alloy beam-column joint connected by channel steel reinforced ring groove rivets. The aluminum alloy beam-column joint connected by the channel steel reinforced ring groove rivets comprises an aluminum alloy I-shaped beam, an aluminum alloy I-shaped column, angular stainless steel connecting pieces, the ring groove rivets and reinforced channel steel, wherein the four angular stainless steel connecting pieces are arranged in pairs at the joint of the beam and the column, are separately arranged at the upper flange and the lower flange of the beam and both sides of a beam web, are connected with column flanges, and two pairs of reinforced channel steel are symmetrically arranged in the column flanges. In addition to the excellent performance possessed bya common beam-column joint, the joint can be quickly assembled on the construction site. In addition to solving the strength reduction problem of welded joints and the electrochemical corrosion problem of bolted joints, the joint has high bearing capacity, initial rotational rigidity, ductility and deformation capacity. As a novel connecting fastener, the ring groove rivets can provide higher pre-tightening force, and prevent looseness and vibration. The novel joint can greatly improve the mechanical properties of the aluminum alloy structure and improve the construction speed of the aluminumalloy structure.

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 structure 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,...
