Problems solved by technology
[0003] Since the traditional split column needs to place a backing plate between the splits, and the position of the backing plate cannot be guaranteed during construction, if the backing plate is inclined, it will inevitably change the thickness of the protective layer of the steel bar, thus affecting the structure of the split column performance

Embodiment Construction
[0015] In order to further illustrate the present invention, the present invention will be described in detail below with reference to the drawings and specific embodiments, but they should not be understood as limiting the protection scope of the present invention.
[0016] Such as figure 1 , figure 2 As shown, a thin-walled steel tube constrained reinforced concrete split column is composed of four thin-walled steel tube constrained reinforced concrete columns 1, and the configuration of longitudinal reinforcement 2 and stirrup 5 of each thin-walled steel tube constrained reinforced concrete column 1 meets " "Code for seismic design of buildings" (GB50011-2010) 6.3.7, 6.3.8 and 6.3.9. The invention has no partition material, and four thin-wall steel pipe-constrained reinforced concrete columns 1 are welded at the top contact points, so that the thin-wall steel pipe-constrained reinforced concrete columns 1 can be compressed and work together.

A novel thin-wall steel tube constraint reinforced concrete split column comprises four thin-wall steel tube constraint reinforced concrete columns. Contact portions of the tops of the thin-wall steel tube constraint reinforced concrete columns are welded through end welding joints. The thin-wall steel tube constraint reinforced concrete columns comprise longitudinal bars, thin-wall steel tubes, concrete and hoops. The longitudinal bars and the hoops are arranged in the thin-wall steel tubes. The longitudinal bars are arranged at four corners of the hoops. The concrete is poured into the thin-wall steel tubes. The novel thin-wall steel tube constraint reinforced concrete split column has the advantages that advantages of conventional split columns are maintained, and the characteristics of the thin-wall steel tube constraint reinforced concrete columns, such as easiness in manufacture and separation and high shear-resisting performance, are utilized fully to form the novel thin-wall steel tube constraint reinforced concrete split column; the concrete is poured into the steel tubes, formworks are not needed, prefabrication in factories can be realized, construction process is simplified greatly, and construction period is shortened.
Description
Technical field [0001] The invention relates to a thin-wall steel tube restrained reinforced concrete split column and a manufacturing method thereof, and belongs to the technical field of reinforced concrete structures. Background technique [0002] In the context of the development of modern buildings, high-rise and super high-rise buildings have become more and more popular, and the problems that follow have become more and more obvious. In order to meet certain needs, some necessary short columns or even super short columns are used in architectural design. These short columns are easily damaged under the action of earthquakes. [0003] Because the traditional split column needs to place a backing plate between the splits, and the position of the backing plate cannot be guaranteed during construction, if the backing plate is inclined, it will inevitably change the thickness of the protective layer of the steel bar, thus affecting the structure of the split column performance....
