Embodiment 1

[0029] Embodiment 1 Steel pipe square reinforced concrete member

[0030] as attached figure 1 As shown, a steel pipe square reinforced concrete member includes a steel pipe 2, concrete 2 and internal steel bars, wherein the internal steel bars are surrounded by concrete and placed inside the steel pipe 1, and the internal steel bars include square stirrups 2 and longitudinal bars 3. The ribs are arranged along square stirrups.

[0031] The cross-sectional size of the entire steel pipe square reinforced concrete is 800mm×4mm×1500mm, the size of the square stirrup is 300mm×300mm, and the diameter of the longitudinal bar is 8mm. One stirrup is arranged every 100mm along the square, and three longitudinal bars are placed evenly on each side. 8, tied and connected with square stirrups.

[0032] The bearing capacity of the square reinforced steel pipe concrete structure is higher than that of the plain steel pipe concrete structure, but lower than that of the circular steel pipe ...

Embodiment 2

[0033] Embodiment 2 steel pipe square reinforced concrete member

[0034] A steel pipe square reinforced concrete member, comprising a steel pipe 2, concrete 2 and internal steel bars, wherein the internal steel bars are surrounded by concrete and placed inside the steel pipe 1, the internal steel bars include square stirrups 2 and longitudinal bars 3, and the longitudinal bars are along the square Stirrup configuration.

[0035] According to the scheme of embodiment 1, the section size of the whole steel pipe square reinforced concrete, the size of the square stirrup, the diameter of the longitudinal bar, the number and position of the setting, and the binding connection of the square stirrup can be determined according to the actual use conditions, in embodiment 1 Adjust and optimize the program.

Abstract

The invention provides a steel-tube square reinforced concrete member. The steel-tube square reinforced concrete member comprises a steel tube, concrete and internal reinforcements, wherein the internal reinforcements are surrounded by the concrete and arranged inside the steel tube, and include a square stirrup and longitudinal bars; the longitudinal bars are arranged along the square stirrup. The steel-tube square reinforced concrete member has the advantages that the section of the member or the thickness of the steel tube is reduced, the construction speed is increased and the fire-resistant performance of the member is good; the steel-tube square reinforced concrete member can be widely applied to civil architecture structure engineering including various high-rise structures, high-rise or ultrahigh-rise buildings, industrial factory buildings, support pillars of ocean platform structures or elevated railway bridges or highway bridges.

Description

technical field [0001] The invention belongs to the technical field of steel pipe concrete for industrial and civil building structures, and in particular relates to a steel pipe square reinforced concrete component and a preparation method and application thereof. Background technique [0002] Now we have a mature technology of concrete-filled steel tube for industrial and civil building structure engineering, including steel tube concrete column and circular reinforced steel tube concrete column. Among them, steel pipe concrete column: a composite material formed by pouring concrete in steel pipes; circular reinforced steel pipe concrete columns; components formed by adding circular steel cages to steel pipe concrete, which have better performance than steel pipe plain concrete. [0003] With the wide application of high-rise and long-span structures, the load of steel-pipe plain concrete is increasing, and the size of components is also increasing, resulting in an increas...
