Abstract
The invention provides a cast-in-place shear wall structure equivalent to a prefabricated sandwiched superposed shear wall continuous steel bar, the cast-in-place shear wall structure is formed by connecting a prefabricated superposed shear wall outer acanthus, an insulating layer, a prefabricated superposed shear wall intermediate plate, a lattice steel bar and a prefabricated superposed shear wall inner acanthus, the upper ends and the lower ends of the prefabricated superposed shear wall intermediate plate and the prefabricated superposed shear wall inner acanthus are all shorter than the prefabricated superposed shear wall outer acanthus and the insulating layer, and the steel bar extends out; in construction and installation, the downward extended steel bars of the upper layer prefabricated superposed shear wall intermediate plate and inner acanthus are respectively fixedly connected with the upward extended steel bars of the lower layer prefabricated superposed shear wall intermediate plate and inner acanthus, and concrete is cast between the intermediate plate and the inner acanthus to form a structure system containing the insulating layer and equivalent to the cast-in-place shear wall. The cast-in-place shear wall structure provided by the invention is insulating and energy-saving, strong in seismic capacity, structure strength and anti-shear capacity, the technical problem that the sandwiched superposed shear wall cannot be applied to the high-rise building is broke through, and the industrial production is realized.
Description
Technical field
The present invention relates to construction engineering technical field, be specifically related to a kind of prefabricated sandwich overlapped shear wall continuity reinforcement(bar) and be equal to cast-in-place shear wall structure.
Background technology
Existing overlapped shear wall, without sandwich heat preservation layer, when its upper and lower layer body of wall is installed, reinforcing bar does not connect mutually, only outside body of wall, in the middle of the cast-in-situ concrete layer between impeller and interior impeller, place vertical reinforcement, the overlapped shear wall that the single reinforcing bar of this levels body of wall connects, anti-shear ability is poor, structural strength is low, generally can only in low-rise building, apply, can not be applied to highrise building, and difficulty of construction be large, cost of labor is high, is unfavorable for suitability for industrialized production application.
Summary of the invention
Technical problem to be solved by this invention is: solve the problem that above-mentioned prior art exists, and provide a kind of prefabricated sandwich overlapped shear wall continuity reinforcement(bar) to be equal to cast-in-place shear wall structure, greatly improve structural strength and the anti-shear ability of the upper and lower layer of building wall connecting, break through the sandwich overlapped shear wall levels of highrise building wall connecting technical barrier, realize the high-quality suitability for industrialized production of highrise building.
The technical solution used in the present invention is:
A kind of prefabricated sandwich overlapped shear wall continuity reinforcement(bar) is equal to cast-in-place shear wall structure, prefabricated sandwich overlapped shear wall is by the outer impeller of prefabricated overlapped shear wall, insulation layer, prefabricated overlapped shear wall intermediate plate, lattice reinforcing bar, in prefabricated overlapped shear wall, impeller connects and composes, in prefabricated overlapped shear wall intermediate plate and prefabricated overlapped shear wall, impeller is upper, lower two ends are all shorter than the outer impeller of prefabricated overlapped shear wall and insulation layer, and stretch out reinforcing bar, during construction and installation, the prefabricated overlapped shear wall intermediate plate in upper strata, interior impeller stretch out downwards reinforcing bar respectively with the prefabricated overlapped shear wall intermediate plate of lower floor, interior impeller protrudes upward reinforcing bar and is fixedly connected with, concreting between the intermediate plate of prefabricated overlapped shear wall and interior impeller, formation contains insulation layer and is equal to the structural system of cast-in-place shear wall.
In technique scheme, the described reinforcing bar that stretches out is fixedly connected with, and adopts connector to be fixed and connects or welding.
In technique scheme, the intermediate plate of described prefabricated overlapped shear wall and interior impeller bottom have two or more precast concrete pin.
The present invention has thoroughly changed conventional art overlapped shear wall without sandwich heat preservation layer, levels wallboard no-reinforcing-bar connects, the original backward situation that structural strength is poor, the present invention makes, the reinforcing bar that stretches out of lower floor's overlapped shear wall is connected and fixed, and be prefabricated with sandwich heat preservation layer, structural strength and the anti-shear ability of overlapped shear wall have greatly been improved, heat preservation energy-saving, construction quality and antidetonation level are got a promotion, particularly the present invention can be applied to highrise building by sandwich overlapped shear wall, and structural strength is high, be equal to cast-in-place shear wall, construction quality is good, manpower and building costs have been saved, realized high efficiency suitability for industrialized production, it is the new breakthrough of Building technology.
