Round aluminum alloy pipe concrete compound column

Abstract

The invention discloses a round aluminum alloy pipe concrete compound column, comprising a hollow cylindrical pipe body which adopts an aluminum alloy material, wherein a connecting piece is arranged on the inner wall of the pipe body, and concrete is filled in the pipe body. In the structural style of the round aluminum alloy pipe concrete compound column, due to the passive hoop effect of the aluminum alloy pipe on the concrete, the characters of concrete that the intensity is greatly improved and the ductility is increased under a three-way compression condition can be fully exerted and utilized, so that the intensity and ductility of the structure are greatly improved. The aluminum alloy has good durability without need of preservative treatment or later maintenance, thereby greatly reducing the construction processes and welding work load. Meanwhile, the aluminum alloy has an esthetic structure, has no need of extra renovation and saves the renovation cost, which is an obvious advantage as compared with round steel pipes. The round aluminum alloy pipe concrete compound column has good integrate technical advantage.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a circular aluminum alloy tubular concrete composite column. Background technique [0002] In the field of civil engineering, the column is the most basic structural form. The commonly used structural forms include reinforced concrete columns, steel structure columns, steel concrete columns, steel pipe concrete columns, etc. These types of column structures are widely used in the field of civil engineering and play a huge role in the development of civil engineering. However, these structural forms also have some deficiencies, which are mainly reflected in: the construction of cast-in-place concrete columns requires formwork, and their bearing capacity and ductility are worse than those of steel structures or concrete-filled steel tubes; Regular maintenance; the amount of steel used in steel concrete columns is also relatively large. In order to ensure a good combina...

However, these structural forms also have some deficiencies, which are mainly reflected in: the construction of cast-in-place concrete columns requires formwork, and their bearing capacity and ductility are worse than those of steel structures or concrete-filled steel tubes; Regular maintenance; the amount of steel used in steel concrete columns is also relatively large. In order to ensure a good combination of steel and concrete, more studs need to be welded on the steel

Concrete-filled steel pipe is a composite column structure with excellent performance. It makes full use of the strength of concrete under the action of three-dimensional stress and has good ductility. Difficult, requiring more welding processes, steel pipes need anti-rust treatment, and regular maintenance
