Prefabricated structural system of steel plate concrete shear wall and its construction method

Abstract

The invention discloses an assembled structure system of a steel plate concrete shear wall, comprising beam components, a steel plate concrete shear wall, a floor slab and a sleeve connector. The steel plate concrete shear wall includes vertical steel plates and continuous spiral stirrups. The assembly rate of this structural system is high. The invention also discloses a construction method of a prefabricated structural system of the steel plate concrete shear wall. The method firstly manufactures the prefabricated steel plate concrete shear wall, then assembles the lower steel plate concrete shear wall, and then installs the lower steel plate concrete shear wall on the lower layer of the steel plate concrete shear wall. Assemble the sleeve connectors, then assemble the beam components and install the floor slabs, and then connect the floor slabs and beam components, as well as the floor slab and the lower steel plate concrete shear wall through concrete pouring, and connect the beam components and the lower steel plate concrete shear wall. Concrete is poured; then the upper steel plate concrete shear wall is hoisted, and finally concrete is poured in-situ at the connection of the upper and lower steel plate concrete shear walls. This method enables construction to be completed with a high assembly rate.

Description

technical field [0001] The invention belongs to the technical field of building structures, and particularly relates to a prefabricated structural system of a steel plate concrete shear wall and a construction method thereof. Background technique [0002] With the popularization of urbanization in my country, the whole country is facing a large demand for new housing. How to quickly solve the residential problems of residents in a short period of time is imminent. The traditional cast-in-place reinforced concrete shear wall structure has a low degree of industrialization, slow construction speed, serious construction site pollution, and huge resource consumption, which is not conducive to the country's sustainable development strategy. On February 21, 2016, the State Council put forward several opinions on further strengthening the management of urban planning and construction: to promote prefabricated buildings, encourage construction enterprises to carry out prefabricated...

Problems solved by technology

Therefore, the amount of steel used is large, which belongs to the steel plate shear wall with high steel content (the steel content is not less than 4%), and the cost is too high, thereby increasing the project cost

[0007] (3) In the existing project, the steel plate-concrete shear wall only exists as a structural component, and no steel plate-concrete shear wall structure system is used in the whole building, and the steel plate shear force is not used in the prefabricated concrete shear wall structure system wall structure

[0008] (4) Built-in single steel plate—concrete shear wall is composed of concrete and steel plate. In order to ensure the stability of the built-in steel plate, the method of full studs is generally used to ensure that the concrete and steel plate work together, but the arrangement of steel bars and studs is dense. The structure is complicated, the construction is difficult, and the cost is high. It is only used in complex structures and super high-rise structures, which leads to the complicated construction of the existing steel plate-concrete combined shear wall structure system, low assembly rate, and limited application range.
