The construction method of the anti-buckling concrete filled steel tube coupled column of above-mentioned built-in circulating type tie hoop comprises the following steps：
Profiled sheet is surrounded into tubular structure；It is adhesive coated to be formed in the inwall coated with adhesive of high intensity thinner tube steel pipe, binding agent
Divide and apply several times coated with guarantee uniform coating thickness；The tubular structure that profiled sheet is formed is arranged in high intensity thinner tube steel pipe,
It will weld between integral circulating type tie hoop is arranged in the tubular structure that high intensity thinner tube steel pipe and profiled sheet surround,
High-strength concrete is poured between the tubular structure that high intensity thinner tube steel pipe and profiled sheet surround until concrete strength reaches requirement.
The present invention has advantages below and prominent effect relative to prior art：
A kind of protrusion of the anti-buckling concrete filled steel tube coupled column of new built-in circulating type tie hoop proposed by the present invention
Feature is that a layer binder and the arrangement circulating type tie hoop between interior outer tube wall are coated between steel pipe and high-strength concrete.
It is adhesive coated effectively to bond steel and concrete, prevent high intensity thinner tube steel pipe from outside local buckling occurs, avoid by
The pillar caused by steel pipe partial flexing destroys, and improves the service efficiency of high-strength steel.Circulating type tie hoop can effectively about
The larger concrete of area of beam periphery stress, improve in coupled column thin-wall high-strength steel pipe for the high-strength concrete in steel pipe about
Shu Bujia situation, avoid high-strength concrete that brittle break is presented, ensure that coupled column is respectively provided with geological process in any direction
Good deformability.On the other hand, tie hoop can provide ring to high-strength concrete and socket power, avoid because concrete with
Concrete ring caused by steel pipe cooperative transformation is to cracking.In addition, the open tubular column structure type of the present invention is ensureing element bearing capacity
On the premise of can save the consumption of material, reduce the cost of coupled column.In summary, the present invention compensate for common high strength steel pipe and mix
The deficiency of solidifying earth pillar, has broad application prospects in skyscraper.
