In order to solve technical problem of the present utility model, the utility model proposes following technical scheme:
A kind of concrete filled steel tube shear wall comprises steel pipe, steel pipe inner concrete, anti-shear ring muscle, external wrapping concrete, transverse reinforcement, longitudinal reinforcement and steel tie; Steel pipe is embarked on journey every the spacing of 2~6 times of diameter of steel tube and is evenly arranged, fills the steel pipe inner concrete in the steel pipe, up counts from the bottom of steel pipe, pastes weldering anti-shear ring muscle every the spacing of 500mm~1000mm at the circumference of steel pipe; Be provided with the steel mesh reinforcement of forming by many transverse reinforcements and Duo Gen longitudinal reinforcement in the both sides, front and back of steel pipe; Pass through the steel tie drawknot between the steel mesh reinforcement of the both sides, front and back of steel pipe, steel tie spacing up and down is the spacing of 2-4 times of longitudinal reinforcement, spacing between the transverse reinforcement is the spacing of 1~6 times of diameter of steel tube, and the spacing of longitudinal reinforcement is the spacing of 1~6 times of diameter of steel tube; Pour into external wrapping concrete between the steel mesh reinforcement of the both sides, front and back of steel pipe.
For further realizing the purpose of this utility model, it is the concrete of C30~C80 that described external wrapping concrete preferably adopts strength grade.
It is the concrete of C60~C120 that described steel pipe inner concrete preferably adopts strength grade, and further preferred employing strength grade is the concrete of C100~C120.
Described transverse reinforcement and longitudinal reinforcement adopt II or III grade reinforcing steel.
Described steel tie adopts I or II grade reinforcing steel.
The relative prior art of the utility model has following advantage and beneficial effect:
(1) the utility model is applied to the advantage of high strength concrete filled steel tube in the shear wall, thereby reduces the sectional dimension of shear wall member significantly, reduces dead load, reduces geological process.
(2) embedded high strength concrete filled steel tube is except that bearing axial compression, and its steel pipe also can be used as tensile reinforcement participation work; The concrete of outsourcing then can adopt ductility preferably than lower intensity level concrete.
(3) this kind steel-concrete compound shear wall initial stiffness is big, supporting capacity is high, and bearing capacity and stiffness degradation are slow during destruction, ductility is good, can avoid the bottom shear sliding rupture, has better anti, is applicable to super-high building structure.
(4) outer wall of high strength concrete filled steel tube pastes along short transverse and is welded with the anti-shear ring muscle, thereby guarantees itself and the ordinary concrete shear wall energy collaborative work of outsourcing.
(5) high strength concrete filled steel tube is because therefore inside and outside all being wrapped in the concrete need not to adopt extra fire prevention measure.
