Fabricated structural system of steel plate reinforced concrete shear walls and construction method of fabricated structural system

Abstract

The invention discloses a fabricated structural system of steel plate reinforced concrete shear walls. The fabricated structural system comprises a beam member, the steel plate reinforced concrete shear walls, a floor and a sleeve connecting piece. Each steel plate reinforced concrete shear wall comprises vertical steel plates and continuous spiral stirrups. The structural system is high in assembling rate. The invention further discloses a construction method of the fabricated structural system of the steel plate reinforced concrete shear walls. The construction method comprises the steps that firstly, one prefabricated steel plate reinforced concrete shear wall is manufactured; secondly, the steel plate reinforced concrete shear wall on the lower layer is assembled; thirdly, the sleeve connecting piece is assembled on the steel plate reinforced concrete shear wall on the lower layer; fourthly, the beam member is assembled, and the floor is installed; fifthly, the floor and the beam member as well as the floor and the steel plate reinforced concrete shear wall on the lower layer are connected by pouring concrete, and concrete is poured to the junction of the beam member and the steel plate reinforced concrete shear wall on the lower layer; and sixthly, the steel plate reinforced concrete shear wall on the upper layer is hoisted, and finally concrete is poured to the junction of the steel plate reinforced concrete shear walls on the upper layer and the lower layer in situ. By adoption of the fabricated structural system of steel plate reinforced concrete shear walls and the construction method of the fabricated structural system, construction can be completed with the high assembling rate.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to an assembled structural system of a steel plate concrete shear wall and a construction method thereof. Background technique [0002] With the popularization of urbanization in our country, the country is facing a large demand for new housing. How to quickly solve residents' housing problems 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 pollution on the construction site, 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 companies to carry out prefabricated constructio...

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.
