Description

Combined concrete shear wall
Technical field
The utility model relates to the building structure technology field, relates in particular to combined concrete shear wall.
Background technology
In recent years, along with rapid development of social economy, the improving constantly of Building technology level, increasing high level, the large complicated building of superelevation layer are rised sheer from level ground.The frequent combination construction system that adopts of super highrise building is to have the new structural system of wind resistance, anti-seismic performance and good economy preferably at present.But; Because the core tube shear wall of combination construction often will be born the seismic shear more than 80%; That have even bear whole shearings, framework only bears vertical force, and structure bottom shear wall ratio of shear span to effective depth of section is generally less; Ratio of axial compressive force to axial compressive ultimate capacity of section is very big again simultaneously, and the anti-seismic performance of total system depends on core tube shear wall bearing capacity and ductility to a great extent like this.In addition, because standard is cut the requirement that anharmonic ratio and housing trestle are born the floor shearing to calculating, cause when the shear wall enlarged in thickness, corresponding increase is also wanted in the cross section of housing trestle, thereby has occurred that cost increases and structural entity is controlled situation of difficult.A kind of bearing capacity of research is high, anti-side rigidity is big, anti-seismic performance good, ductility is high, the compound shear wall of reasonable stress so press for.
Summary of the invention
In order to overcome existing shortcoming and defect, the purpose of the utility model is to provide the bearing capacity height, anti-side rigidity is big, anti-seismic performance good, ductility is high, the combined concrete shear wall of reasonable stress.
The concrete technical scheme of the utility model is following:
Combined concrete shear wall; Comprise body of wall, side column, said body of wall is fixedly connected with side column, and said body of wall comprises binding bar array, double-level-metal plate; Constitute interlayer between this double-level-metal plate; In interlayer, be provided with concrete panel, said binding bar array passes the double-level-metal plate, and concrete panel is fastened in the interlayer of double-level-metal plate through the binding bar array.The distribution form of said binding bar array is block form arrayed or quincunx arrayed.Said binding bar array is made up of several bolts.
Said side column is the concrete filled steel tube side column that steel pipe and interior concrete column thereof constitute, and the steel pipe of said concrete filled steel tube side column and the welding of double-level-metal plate are fixing.
Square bar is anchored or is welded with back timber on the said body of wall; Said back timber is any one in girder steel, reinforced concrete beam or the girder with rolled steel section en cased in concrete.
The cross sectional shape of said concrete filled steel tube side column is square, rectangle, is provided with the binding bar array along the vertical direction total length of concrete filled steel tube side column.Certainly, the cross sectional shape of concrete filled steel tube side column also can be circular configuration.
The beneficial effect of the utility model is:
1, the utility model body of wall comprises binding bar array, double-level-metal plate; Constitute interlayer between this double-level-metal plate; In interlayer, be provided with concrete panel, said binding bar array passes the double-level-metal plate, and concrete panel is fastened in the double-level-metal plate through the binding bar array.Improve the structural entity anti-seismic performance, make structure have the dual seismic defence line, combination construction center trestle and shear wall can better be coordinated in deformation process.
2, give full play to that concrete filled steel tube side column bearing capacity is high, ductility is good; Initial stiffness that characteristics such as anti-seismic performance is good and concrete panel are bigger and steel plate wall large deformation ability, good plasticity ability, the characteristic such as hysteresis of stablizing; The realization total cross-section is stressed, and said compound shear wall shows good capacity under axial, shear-carrying capacity and anti-seismic performance.
3, the binding bar array closely links double-level-metal plate and concrete panel and co-operation; Binding bar array, double-level-metal plate and concrete filled steel tube side column can form constraint to concrete in the wall; Effectively improve concrete stress performance; Improve bearing capacity of concrete-filled and deformability, avoid peeling off too early after the concrete compression damage and deactivate.
4, adopt binding bar to connect, easy construction, power transmission mechanism is clearer and more definite, is beneficial to theory analysis; When having avoided employing stiffening rib or peg, difficulty of construction reaches welding connecting mode greatly, may cause damage to a certain degree with regard to little side plate originally to thickness, forms stress in the commissure easily and concentrates.
5, the concrete panel in the double-level-metal plate can stop the inside flexing of metal sheet effectively, and the binding bar array can be postponed the outward bulge song of metal sheet effectively, thereby the stress performance of metal sheet is not fully exerted.The concrete filled steel tube side column can increase the out-of-plane rigidity of this patent combined concrete shear wall.
6, adopt this patent combined concrete shear wall, reduce the thickness of wall, increase the building usable floor area, easy construction and can save template can be adopted contrary sequence method, accelerating construction progress.Textural, conveniently there be some structures floor girder steel and core inner core to be made and rigidly connect, and the connected node reliability is guaranteed in order to increase the rigidity of structure.
7,, can not impact building or decorative appearance because the double-level-metal plate is arranged in the external surface of concrete panel, and the double-level-metal plate is in the elastic force balance state under the normal operating condition, external crack or flexing can not occur.
