Concrete filled steel tube core column reinforced prefabricated assembly type shear wall unit

Abstract

The invention discloses a prefabricated assembly type concrete filled steel tube core column reinforced shear wall unit, and belongs to the field of constructional engineering. The shear wall unit comprises a double-layer reinforcing mesh, outer wrapped concrete and lacing wires and further comprises a plurality of round concrete filled steel tube core columns, and the round concrete filled steel tube core columns are vertically fixed into a cavity of the double-layer reinforcing mesh at an equal interval; after the reinforcing mesh and steel tubes are fixedly bound, the outer wrapped concrete is poured to form a shear wall; the upper ends of the round concrete filled steel tube core columns and the lower ends of the round concrete filled steel tube core columns stretch out of the outer wrapped concrete, and the round concrete filled steel tube core columns are composed of round steel tubes and concrete poured in cavities of the round steel tubes in a filled mode. According to the prefabricated assembly type concrete filled steel tube core column reinforced shear wall unit, by the utilization of the high bearing capacity and the high ductility of the concrete filled steel tube core columns, the anti-bending capacity, the shearing resistance and the hysteretic energy dissipation capacity of the shear wall are effectively improved, and good anti-seismic property is achieved. The prefabricated assembly type concrete filled steel tube core column reinforced shear wall unit is simple in construction technology, the overall quality of a building can be guaranteed through prefabrication and site assembly, the construction operation speed is improved, and the labor intensity is lowered.

Description

technical field [0001] The invention discloses a steel pipe concrete core column stiffened prefabricated assembly type shear wall unit, which is an anti-seismic shear wall which is easy to assemble on site and prefabricated in a factory, and belongs to the field of construction engineering. Background technique [0002] Today, with the rapid development of the construction industry, higher construction requirements for low-carbon, green, environmentally friendly and efficient buildings are put forward. The building structure is split into several building components, prefabricated in the factory, and transported to the site for assembly. Eliminate dust, noise and other environmental pollution on the construction site, improve production efficiency, save a lot of labor costs, build houses like cars, and set off a new revolution in the industrialization of construction. [0003] In prefabricated buildings, the earthquake resistance of the house is the key. A large number of st...

Problems solved by technology

[0003] In prefabricated buildings, the earthquake resistance of the house is the key. A large number of steel bars need to be arranged in the conventional reinforced concrete shear wall to resist the earthquake shear force. At present, domestic factories have not fully mechanized the processing of steel mesh, steel cage and other products. , to a large extent rely on manual processing and binding of steel bars, so that the cost of processing and manufacturing shear wall steel bars has been high, and the production efficiency is low, so it is difficult to supply the demand for automatic table formwork production of shear wall
