Precast steel pipe concrete laminated column

Abstract

The invention relates to a precast steel pipe concrete laminated column comprising a foundation and a plurality of steel pipe concrete segments. The steel pipe concrete segments comprise the bottom segment, the top segment and one or more intermediate segments. Each steel pipe concrete segment comprises a lower steel plate, a steel pipe concrete main body and an upper steel plate which are fixedly connected in sequence. The bottom segment and the corresponding intermediate segment are fixedly connected through connecting anchor bolts, and the corresponding intermediate segment and the top segment are fixedly connected through connecting anchor bolts. Bottom anchor bolts are arranged on the upper surface of the foundation. The bottom segment is fixed to the foundation by means of connection of the lower steel plate of the bottom segment and the bottom anchor bolt. The precast steel pipe concrete laminated column has the characteristics of high bearing capacity, good anti-seismic performance and excellent durability and can be precast and manufactured in a factory or a different place in advance, the defect of complex procedures of traditional cast-in-situ concrete construction is avoided, and the precast steel pipe concrete laminated column has the advantages that the construction speed is high, the influence on the environment is small, the construction period is short, construction noise is low, material stacking sites are few, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a prefabricated steel tube concrete composite column. Background technique [0002] Modern civil engineering is developing in the direction of large scale, complex structure, and diversified functions, which promotes the development of high-strength concrete. At present, high-strength concrete structures with steel pipes are used, and high-strength concrete is restrained by steel pipes, which improves the brittleness of high-strength concrete. Improve the seismic capacity of the structure. In order to overcome the shortcomings of poor corrosion resistance and fire resistance of steel pipes, ordinary reinforced concrete is poured around the high-strength steel pipe concrete to form a composite structure of high-strength steel pipe high-strength concrete with reinforced concrete outside, but this structure cannot guarantee the high-strength steel pipe high-strength concre...
