Square covering square hollow sandwiched carbon fiber steel rib-steel pipe concrete combined column

Abstract

The invention relates to the field of structural engineering in civil engineering, in particular to a square covering square hollow sandwiched carbon fiber steel rib-steel pipe concrete combined column. The combined column can save the consumption of concrete, lighten the dead weight of members and reduce the construction difficulty of cast concrete, and has high flexural rigidity and torsional rigidity. The combined column comprises a core steel pipe, concrete, angle steels, an external angle steel, batten plates and carbon fiber cloth; the angle steels with square sections on four angles and the batten plates form an external steel framework; the core steel pipe is placed in the steel framework; the centroid of the square steel pipe can be superposed with that of the steel framework; the concrete is filled between the steel framework and the core steel pipe; and the carbon fiber cloth is wrapped outside a steel pipe concrete column. The concrete is not poured into the steel pipe, so the steel pipe is hollow. According to the combined column, the consumption of materials is saved, the rigidity and the ductility of the members are improved, the construction difficulty in pouring the concrete is reduced, and the combined column has good heat insulation and sound insulation properties.

Description

technical field [0001] The invention relates to the technical field of structural engineering in civil engineering, in particular to a square hollow interlayer carbon fiber steel frame-concrete steel tube composite column. Background technique [0002] The steel-reinforced steel-concrete-filled steel column overcomes the deficiencies of steel-reinforced concrete and steel-filled steel-filled columns to a certain extent, and develops the strengths of both. It is a new structural form. This column can make use of the advantages of the hollow steel-reinforced concrete column to make up for the shortcomings of the steel-filled steel-reinforced concrete column. Carbon fiber reinforcement technology is a new, efficient and convenient structural reinforcement technology emerging in the world. It uses resin cementing materials to paste carbon fiber cloth on the surface of structural components, and works with it to reinforce structural components and improve mechanical properties. ...
