Description
Technical field
The utility model belongs to a kind of shear wall, particularly a kind of shear wall of built-in dark support.
Background technology
Casualties that violent earthquake causes and property loss are very huge.The key of antidetonation mitigation is to strengthen the shock resistance of building.Reinforced concrete shear wall is the particularly core antidetonation parts of high building structure of building structure, and it is widely used in frame-shear wall structure, framework one tube structure, shear wall structure, steel one concrete composite structure.Shear wall is being born the geological process of structural entity 80% approximately.Yet the ductility of shear wall is relatively poor, has influenced giving full play to of its structural entity anti-seismic performance.Therefore, ductility and the comprehensive anti-seismic performance of improving shear wall is the problem of very paying close attention to both at home and abroad always.Have in the existing scheme of improving shear wall and in reinforced concrete shear wall, add the dark technology that supports of steel plate.The problem of its existence is, in the later stage of shear wall elastic-plastic deformation since steel plate support around not with its vertical muscle in the same way and the constraint of the concrete nuclear core bundle that forms of corresponding stirrup, steel plate easily produces the plane outcurve and bends and lose its shock resistance.Inventor of the present utility model has proposed dark shear wall, the gain the national patent (patent No.: ZL97244563.3) of supporting of band from improving shear wall self energy dissipation capacity and bearing capacity angle.This band secretly supports shear wall, be on common shear wall arrangement of reinforcement basis, add to join to form behind vertical muscle of dark support and the stirrup and be with oblique steel concrete nuclear core bundle, dark support can limit or postpone the development of diagonal crack to main diagonal crack, bootable horizontal curvature crack makes progress many distributions to have increased plastic hinge power consumption region height from the bottom, thinner and close and range of distribution is wide than common shear wall crack, destructiveness is lighter, bearing capacity and stiffness degradation are slow, and the later stage anti-seismic performance is relatively stable.But still there is weak point in above-mentioned utility model: its oblique dark supporting core partly is concrete, and tension, anti-pressure ability are still not enough.
Summary of the invention
Technical problem to be solved in the utility model is the problem that significantly improves the shear wall shock resistance, in order to address the above problem, the utility model has designed built-in " shaped steel-reinforcing bar " the compound dark support shear wall of concrete, it is compared with common shear wall, can significantly improve the shock resistance of carrying shear wall, because shear wall is the core lateral resisting parts of building structure, improved the shock resistance of shear wall, also just improved the whole shock resistance that shear wall structure is arranged, when building meets with violent earthquake, can alleviate its earthquake, prevent that it from collapsing.
The technical solution adopted in the utility model is: the compound dark support shear wall of built-in " shaped steel-reinforcing bar " concrete, constitute by frame columns 1 and shear wall slab, the steel mesh reinforcement that configuration is made up of horizontal and vertical distribution reinforcement in shear wall slab, between steel mesh reinforcement, socket with socketing reinforcing bar 16, between horizontal and vertical steel mesh reinforcement, add and be furnished with oblique tendon, oblique tendon has been provided with the stirrup of effect of contraction, it is characterized in that: add shaped steel bearing diagonal 11 at oblique tendon core.
Described shear wall, it is characterized in that: the composite supporting that is made of reinforcing bar bearing diagonal 10 and shaped steel bearing diagonal 11 that installs in the shear wall slab steel mesh reinforcement is herringbone, anchoring in the upper side frame beam is stretched in the upper end of its reinforcing bar bearing diagonal 10 and shaped steel bearing diagonal 11, the frame anchoring is stretched into from two ends of lower frame beam respectively in the lower end, vertical muscle of bearing diagonal and stirrup formation bearing diagonal cage of reinforcement affixed on it.
Described shear wall, it is characterized in that: the composite supporting that is made of reinforcing bar bearing diagonal 10 and shaped steel bearing diagonal 11 that installs in the shear wall slab steel mesh reinforcement is X-shaped, anchoring in the upper side frame beam is stretched in the upper end of its reinforcing bar bearing diagonal 10 and shaped steel bearing diagonal 11, the frame anchoring is stretched into from two ends of lower frame beam respectively in the lower end, vertical muscle of bearing diagonal and stirrup formation bearing diagonal cage of reinforcement affixed on it.
Described shear wall, it is characterized in that: the composite supporting that is made of reinforcing bar bearing diagonal 10 and shaped steel bearing diagonal 11 that installs in the shear wall slab steel mesh reinforcement is splayed, anchoring in the upper side frame beam is stretched in the upper end of its reinforcing bar bearing diagonal 10 and shaped steel bearing diagonal 11, the frame anchoring is stretched into from two ends of lower frame beam respectively in the lower end, vertical muscle of bearing diagonal and stirrup formation bearing diagonal cage of reinforcement affixed on it.
The compound dark support shear wall of built-in " shaped steel-reinforcing bar " concrete, secretly support shear wall, be with steel concrete secretly to support the supporting capacity raising of shear wall than existing common shear wall, band steel plate, bearing capacity and stiffness degradation are slow, the later stage anti-seismic performance is relatively stable, and the bottom shear sliding rupture alleviates.
