The construction method of above-mentioned prefabricated assembled steel reinforced concrete shear walls, carry out in the steps below:
A, be prefabricated in the factory shear wall sheet (1), and be transported to job site;
B, shear wall sheet is lifted, marginal zone anchor slab reinforcing bar and i shaped steel under the shear wall sheet on upper strata is made to reserve end, aim at shear wall sheet upper limb embedded bar branch sleeve and the shaped steel branch sleeve of lower floor, then dropping place, by upper, lower floor's shear wall sheet location, support, fixing, and high-strength grout is poured into a mould in embedded bar branch sleeve and shaped steel branch sleeve, treat the whole installation in position of shear wall sheet of same layer, and after high-strength grout intensity reaches requirement, according to working procedure upper, the steel mesh reinforcement of cloth cast-in-situ floor formwork in headspace in the middle of lower shear wall sheet, then the concrete of cast-in-situ floor is poured into a mould, after maintenance completes, remove temporary support,
C, carry out the construction of the prefabricated assembled steel reinforced concrete shear walls sheet of other floors successively, finally form integral prefabricated assembling steel reinforced concrete shear walls.
Adopt the present invention of technique scheme, compared with prior art, its beneficial effect is:
Fully merge the advantage of steel reinforced concrete and reinforced concrete shear wall, enhanced supporting capacity and the rigidity of shear wall, improve ductility and the energy-dissipating property of shear wall; Compared with steel pipe concrete frame shear wall, this structural system can according to building height and shear wall width, by effectively controlling the content of steel, longitudinally shaped steel is evenly arranged in shear wall, concrete shear body of wall is divided into many shear wall aggregates according to shaped steel position, correspondingly reduce the coordination stress deformation between steel reinforced concrete and concrete shear force wall, and the anti-seismic performance of body of wall and stress characteristic are all relative optimizes.
