Cast-in-place shear wall structure equivalent to prefabricated sandwiched superposed shear wall continuous steel bar

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 [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated sandwich laminated shear wall continuous reinforcement equivalent to a cast-in-place shear wall structure. Background technique [0002] The existing laminated shear wall has no sandwich insulation layer. When the upper and lower walls are installed, the steel bars are not connected to each other. Only vertical steel bars are placed in the middle of the cast-in-place concrete layer between the outer leaf plate and the inner leaf plate of the wall. , this kind of superimposed shear wall connected by a single steel bar on the upper and lower walls has poor shear resistance and low structural strength. Generally, it can only be applied in low-rise buildings, not high-rise buildings. Moreover, the construction is difficult and the labor cost is high. , which is not conducive to industrial production and application. Contents of the invention [000...
