For achieving the above object, the technical solution adopted in the utility model is: a kind of concrete-filled steel tube shear wall, the steel pipe that cross section is rectangle is provided with in this shear wall one end edge member, being provided with cross section in other end edge member is circular steel pipe, is cast with concrete in the steel pipe of described cross section to be steel pipe and the cross section of rectangle be circle.Conveniently construct, make full use of steel tube section characteristic, arranging rectangle steel pipe end should be rigidly connected with flooring girder steel, and arranging circular steel pipe end should be connected with coupling beam.
Further, the concrete grade of pouring into a mould in described cross section to be the steel pipe of rectangle and cross section be circular steel pipe is more than or equal to shear wall concrete.
Further, described shear wall is reinforced concrete shear wall.
Further, the described cross section shear wall that to be the steel pipe of rectangle and cross section be between circular steel pipe is provided with one or more in vertical reinforcement, stirrup and lacing wire.
Further, described cross section is circular thickness of steel pipe is 5 ~ 50cm.
The preparation process of the utility model concrete-filled steel tube shear wall is as follows: be placed in by steel pipe in shear wall edges at two ends component, rectangular steel pipe is set with the flooring girder steel end that is rigidly connected, round steel pipe is set with coupling beam link, high performance concrete is built in steel pipe, steel pipe inner concrete label is not less than the outer concrete grade of steel pipe, and the peg on steel pipe and steel pipe completes in advance in steel work processing factory.In concrete-filled steel tube shear wall, the identical method construction of ordinary reinforced concrete shear wall pressed by longitudinal reinforcement, stirrup, first builds the concrete in steel pipe, the concrete outside after-pouring steel pipe.
Another object of the present utility model also discloses a kind of building, this building comprises girder steel, coupling beam and above-mentioned concrete-filled steel tube shear wall, conveniently construct, make full use of steel tube section characteristic, described concrete-filled steel tube shear wall is provided with steel pipe that cross section is rectangle and girder steel is rigidly connected, and it is that circular steel pipe end is connected with coupling beam that described concrete-filled steel tube shear wall is provided with cross section.
The utility model concrete-filled steel tube shear wall is simple and reasonable for structure, compact, has the following advantages compared with prior art:
1. the utility model arranges steel pipe in shear wall edges at two ends component, and in steel pipe, build the concrete-filled steel tube shear wall of high performance concrete formation, improves bearing capacity and the ductility of shear wall structure component, makes it meet structural seismic performance designing requirement.
2. in shear wall end edge component, arrange steel pipe, because wall inside and outside steel pipe has concrete to wrap up, local stability increases substantially, and the flakiness ratio of rectangular steel pipe, the radius-thickness ratio of round steel pipe can be unrestricted, and therefore steel pipe can adopt high strength steel.
3. the side direction template that the utility model is arranged when the built-in steel pipe of shear wall edges at two ends component can be and builds concrete outside shearing wall coil provides lateral support.
4. due to the restriction of steel pipe manufacturing technique, round steel pipe wall thickness can not too thick, radius-thickness ratio can not be too little, the wall thickness of rectangular steel pipe is then unrestricted, just connect link with flooring girder steel to arrange rectangular steel pipe, arrange round steel pipe with coupling beam link, different cross section steel tube performance can be made full use of, and constructability.
5. the utility model concrete-filled steel tube shear wall simple structure, easy construction, saves the construction period, reduces construction cost.
Except specified otherwise, in the utility model, round steel pipe refers to that cross section is circular steel pipe, and rectangular steel pipe refers to that cross section is the steel pipe of rectangle.About concrete in the utility model patent, vertical muscle, stirrup, steel pipe, being welded to connect between steel work, the requirement of processing and construction all can by " Code for design of concrete structures " (GB50010-2010), " Code for design of steel structures (GB50017-2003), " seismic design provision in building code " (GB50011-2010), " highrise building steel-concrete combined structure design discipline " (CECS230:2008), the specifications such as " technical specification for concrete structures of high-rise building " (Guangdong Province standard DBJ15-92-2013), code performs.
