Assembled steel tube high-strength concrete columns and construction method thereof

Abstract

The invention relates to the technical field of assembled steel tube high-strength concrete columns, and discloses the assembled steel tube high-strength concrete columns and a construction method thereof. The assembled steel tube high-strength concrete columns are formed by sequential connecting of prefabricated standard column joints, and the standard column joints comprise steel tubes, high-strength concrete, stiffening ribs and ordinary concrete, wherein the high-strength concrete is poured in the steel tubes; the stiffening ribs are arranged on the outer side of the steel tubes in a surrounding mode, and the ordinary concrete is poured at the outside of the steel tubes; the high-strength concrete is high-strength concrete with added iron tailings and construction waste; vertical rib groups are fixed to the inner walls of the steel tubes in a welded mode; horizontal end plates are arranged on the outer circumferences of the steel tubes along the section direction in a surrounding mode; through holes are evenly formed in the horizontal end plates at intervals; the stiffening ribs penetrate through the through holes and are arranged in the length directions of the steel tubes in a full-length mode; one ends of the stiffening ribs extend out of the standard column joints, and the other ends of the stiffening ribs are provided with half grouting sleeves which are connected with the stiffening ribs extending out of the adjacent standard column joints. The assembled steel tube high-strength concrete columns are fireproofing, corrosion resisting, high in bearing capacity, and excellent in durability.

Description

technical field [0001] The invention relates to the technical field of assembled steel pipe concrete columns, in particular to an assembled steel pipe high-strength concrete column and a construction method thereof. Background technique [0002] With the rapid development of domestic urbanization, the disadvantages of traditional reinforced concrete structures and cast-in-place construction methods have gradually emerged, such as serious environmental pollution, high material and energy consumption, low recyclability of building materials, long construction period, and high cost. Advanced issues are gradually unable to keep up with the pace of modernization. Due to its advantages of green environmental protection and high construction efficiency, prefabricated buildings have gradually developed into the mainstream direction of modern structural buildings. The standardized prefabrication of components and the connection between components have also become a hot spot of resea...

Problems solved by technology

[0005] The technical problem to be solved is: the existing steel pipe concrete column has poor fireproof performance, and because the steel pipe is directly exposed, it is prone to corrosion, and with the prolongation of service time, cracks and gaps are likely to occur between the concrete and the steel pipe, and the durability is poor
