Aluminum alloy pipe concrete composite column with internal restraining plate

Abstract

The invention discloses an aluminum alloy pipe concrete composite column with an internal restraining plate. The aluminum alloy pipe concrete composite column is structured as follows: an aluminum alloy pipe forms a column body, sealing covers are fixedly connected to the two ends of the column body, and connecting pieces are arranged on the outer sides, relative to the column body, of the sealing cover; each connecting piece is a square body with a through sidewall, bottom walls are provided with threaded holes, and are fixedly connected with the sealing covers through reinforcing screws, and threaded holes are formed in top walls and the sidewalls, and are connected with composite beams penetrating through the connecting pieces through the reinforcing screws; the restraining plate is integrally formed in the column body, and cavities of the aluminum alloy pipe and the restraining plate are filled with concrete; the aluminum alloy pipe has a thickness b and a pipe wall thickness d, the pipe wall is d, the wall thickness of the restraining plate is t, and in order to ensure the stability of the whole structure, d=(1 / 25-1 / 40)*b and t=(1 / 40-1 / 50)*b. The aluminum alloy pipe concrete composite column with the internal restraining plate is high in structure bearing capacity and durability, easy to construct, attractive in design, light in weight and low in cost, and has high economic value and practical value.

Description

technical field [0001] The invention relates to the field of application of new materials and new structural systems in construction engineering, in particular to an aluminum alloy tubular concrete composite column with internal restraint plates. Background technique [0002] In the field of construction 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 structural forms of columns are widely used in the field of construction engineering and play a huge role in the development of construction engineering. 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.
