Corrugated aluminum alloy pipe and concrete combination column

Abstract

The invention discloses a corrugated aluminum alloy pipe and concrete combination column. The corrugated aluminum alloy pipe and concrete combination column comprises an aluminum alloy pipe and concrete stuffed in the aluminum alloy pipe, wherein the concrete can be plain concrete or high performance concrete; the aluminum alloy pipe is a corrugated aluminum alloy pipe; and a reinforcing cage canalso be arranged in the aluminum alloy pipe, the reinforcing cage is made through binding up of longitudinal reinforcing bars and hoop bars, and the shape of the section of the reinforcing cage coincides with the shape center of the section of the corrugated aluminum alloy pipe. According to the corrugated aluminum alloy pipe and concrete combination column disclosed by the invention, the aluminumalloy pipe lighter in materials is used for restraining the concrete. Compared with a traditional steel pipe and concrete structure, the corrugated aluminum alloy pipe and concrete combination columnhas the advantages that the restraining effects are similar, but the self weight of structural members is lighter; when the corrugated aluminum alloy pipe is used, the situation that the pipe wall ofthe aluminum alloy pipe is untimely bent when the corrugated aluminum alloy pipe is pressed can be avoided; and besides, the cohesive force of the aluminum alloy pipe and the concrete can be improved. The corrugated aluminum alloy pipe and concrete combination column disclosed by the invention adopts a structure measure of synergy work of the corrugated aluminum alloy pipe and common concrete orreinforcing bar concrete or high performance concrete, is simple in structure and convenient to construct, and has the advantages of being light in weight, good in synergy work of different materials,high in bearing capacity and good in shock resistance.

Description

technical field [0001] The invention relates to a bearing structure, in particular to a corrugated aluminum alloy tubular concrete column. Background technique [0002] The aluminum alloy tube concrete column is a structural member made of aluminum alloy tube filled with concrete. Compared with the traditional steel tube concrete column, the aluminum alloy tube concrete column has a smaller self-weight, and the density of the steel is 7850kg / m 3 , the density range of typical grades of aluminum alloy is 2720kg / m 3 -2820kg / m 3 , the density of aluminum alloy is about one-third of the density of steel, and the tensile strength of aluminum alloy is similar to or better than that of steel. Under the action, the concrete is in a three-dimensional compression state, which can delay its longitudinal cracking during compression, thereby increasing the strength of the concrete, and improving the plasticity and toughness. When the aluminum alloy tubular concrete column is applied ...
