Description
Technical field
The utility model belongs to a kind of construction work concrete filled steel tube field, specifically relates to a kind of high tensile steel tube concrete structure.
Background technology
Concrete filled steel tube is as the main material of construction work, bear the heaviest weight load task, existing construction work is more and more grander, the intensity of concrete filled steel tube needs increasing, time particularly as bridge construction key member, the current railroad bridge of China and highway bridge mainly adopt reinforced concrete bridge pier, it should be noted that, reinforced concrete bridge pier is to have the rigidity of structure large, fatigue behaviour is good, good and the cost of normability is rationally etc. while feature performance benefit, also ubiquity stirrup restraint is weak, ductility is on the low side, the shortcomings such as the low and poor seismic behavior of shear strength, easily because of bridge pier shearing resistance, Compressive Bearing Capacity and deformability on the low side and shear failure occurs, Subjected To Compression, Bending, Shear And Torsion combined failure and toppling such as to be collapsed at the damage-form, in recent domestic earthquake centre in multiple times, reinforced concrete bridge pier is all had to destroy serious and be difficult to repair Earthquake damages generation, after earthquake centre disaster relief and rescue and calamity, reconstruction work causes very large difficulty over the ground.Therefore, in effort raising with while improving conventional steel bar concrete bridge pier anti-seismic performance, innovative development high strength steel pipe concrete also day by day becomes current bridge engineering circle and pays close attention to one of problem and study hotspot.
Utility model content
The technical problems to be solved in the utility model is to provide the simple high tensile steel tube concrete structure of a kind of structure.
Content of the present utility model comprises rectangular steel tube, described rectangular steel tube inside is provided with round steel pipe, outer reinforcing bar is connected with between described rectangular steel tube and round steel pipe, described rectangular steel tube and the inner fill concrete of round steel pipe, one end of described outer reinforcing bar is fixed on round steel pipe, the junction of the dual-side of other end contact rectangular steel tube.
Described round steel pipe inside is provided with interior reinforcing bar, and described interior reinforcing bar and outer reinforcing bar are crisscross arranged.
The number of described outer reinforcing bar is 4.
The number of described interior reinforcing bar is 4.
The beneficial effects of the utility model are, steel pipe of the present utility model comprises rectangular steel tube and round steel pipe, outer reinforcing bar is provided with between rectangular steel tube and round steel pipe, one end of outer reinforcing bar is arranged in the corner of rectangular steel tube, the i.e. junction of two side plates, the other end connects round steel pipe, the structural strength of such structural strengthening between rectangular steel tube and round steel pipe, ensure that lateral compressive strength of the present utility model, simultaneously, the utility model has 2 steel pipes, strengthens vertical compressive strength of the present utility model.
