Embodiment Construction
[0024] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, but it is not intended to limit the protection scope of the present invention.
[0025] Such as figure 1 and figure 2 As shown, the square steel pipe high-strength concrete column with parallel bundled spiral stirrups includes square steel pipe 4, spiral stirrup 1, longitudinal reinforcement 2 and high-strength concrete 3; The inner edge of the stirrup 1 is longitudinally bound or welded with a plurality of longitudinal bars 2 to form a reinforced cage with bundled spiral stirrups;
[0026] The square steel pipe has 4 side lengths of 2000 mm, is formed by welding steel plates with a wall thickness of 40 mm, and the steel strength is Q390; the spiral stirrup 1 adopts a steel bar with a diameter of 16 mm, and the longitudinal bar 2 uses a steel bar with a diameter of 30 mm. The strength grades of the above steel bars are HRB400; the ...

Abstract
The invention discloses a square steel pipe high-strength concrete column with parallel bundled spiral stirrups, including square steel pipes, spiral stirrups, longitudinal bars and high-strength concrete; there are four spiral stirrups, which intersect two by two, and longitudinally in the intersecting area and the inner edge of the spiral stirrups Bind or weld multiple longitudinal bars to form a reinforced cage with bundled spiral stirrups; the reinforced cage with bundled spiral stirrups is placed in a square steel pipe, and the inner cavity of the square steel pipe is poured with high-strength concrete. The high-strength concrete column of the square steel pipe with bundled spiral stirrups has the advantages of simple structure, convenient construction, good ductility, high bearing capacity and superior seismic performance, and is suitable for piers of super high-rise buildings, industrial heavy factory buildings and long-span bridges.
Description
technical field [0001] The invention belongs to vertical load-bearing components of building structures, in particular to high-strength concrete columns of square steel pipes equipped with bundled spiral stirrups. Background technique [0002] In the field of civil engineering, building materials and material combinations have undergone diversified development. The most widely used materials are steel and concrete. According to the different combinations of steel and concrete, they are divided into three main types: reinforced concrete, section steel concrete, and steel pipe concrete. According to the strength of concrete, concrete is divided into ordinary concrete and high-strength concrete. [0003] Reinforced concrete with spiral stirrups belongs to reinforced concrete and is mainly used for circular frame columns and pile foundations. The characteristics of spiral stirrup reinforced concrete are: when the column is under compression, the spiral stirrup can produce a str...
