Aluminum alloy semi-rigid beam-column joints connected by ring groove rivets

Abstract

The invention discloses an aluminum alloy semi-rigid beam and column joint connected through ring groove rivets. The aluminum alloy semi-rigid beam and column joint comprises an aluminum alloy I-shaped beam, an aluminum alloy column and the ring groove rivets; the end face of the aluminum alloy I-shaped beam is in butt joint with flanges of the aluminum alloy column, and the aluminum alloy I-shaped beam and the aluminum alloy column are connected through angular stainless steel connection pieces; and the four angular stainless steel connection pieces are arranged at the junction of the beam and the column in pairs, arranged on upper and lower flanges of the beam and the two sides of a beam web correspondingly, and connected with the column flanges correspondingly. The joint further has thevery high bearing capacity and initial rotation stiffness besides having excellent performance of common joints, for example, the joint can be quickly assembled on a construction site, and the strength reduction problem of welding joints and the problem of electrochemical corrosion of bolt connecting joints can be solved; the ring groove rivets, serving as novel connecting fasteners, can providehigh pre-tightening force, prevent loosening and resist vibration; and the novel joint can greatly improve mechanical performance of an aluminum alloy structure, increase the construction speed of thealuminum alloy structure, and help to solve the problem of excess capacity of electrolytic aluminum in China by being extensively used in engineering.
