Novel assembly type aluminum alloy anti-seismic frame structure

Abstract

The invention discloses a novel assembly type aluminum alloy anti-seismic frame structure. Each stainless steel T-shaped connecting plate is composed of a connecting plate flange and a connecting plate web integrally and fixedly connected to the middle of the flange, and two rectangular I-shaped column base plates are arranged on the inner side of the aluminum alloy I-shaped column flange; the connecting plate webs in the pair of stainless steel T-shaped connecting plates which are oppositely arranged are oppositely arranged and are connected through two aluminum alloy groove-shaped beams; at least one rectangular groove-shaped beam base plate is mounted between the two aluminum alloy groove-shaped beams; and the upper portion of each connecting plate flange is connected with a groove-shaped beam flange above the corresponding aluminum alloy groove-shaped beam through an upper stainless steel angle connecting piece, the middle of the connecting plate flange is connected with a groove-shaped beam web through a middle stainless steel angle connecting piece, and the lower portion of the connecting plate flange is connected with a lower groove-shaped beam flange through a lower stainless steel angle connecting piece. The stainless steel T-shaped connecting plates can effectively gather the beams, the columns and the supports at one position, and the integrity of the frame structure is improved.

Description

technical field [0001] The invention belongs to the technical field of general building structures, in particular to a novel assembled aluminum alloy anti-seismic frame structure. Background technique [0002] Because aluminum alloy has good corrosion resistance, high specific strength, easy extrusion performance and beautiful appearance, it is gradually favored by structural engineering. There are more than 10,000 aluminum alloy structures at home and abroad. The main application scopes are long-span space structures, bridge structures, movable structures and high-rise structures, but the engineering examples for frame structures are very limited. The density of aluminum alloy is only 1 / 3 of steel, and its lower self-weight makes it more suitable for prefabricated structures than steel. However, due to the lack of reasonable node forms and the connection system between frame members and nodes, its application is greatly restricted. limits. [0003] At present, the applica...
