Method for manufacturing and assembling prefabricated concrete filled steel tube core column stiffening shear wall

Abstract

The invention discloses a method for assembling a prefabricated concrete filled steel tube core column stiffening shear wall. According to the prefabricated shear wall, concrete filled circular steel tube core columns are vertically arranged and fixed in two layers of reinforcing meshes at certain intervals, the two layers of reinforcing meshes are fixed through tie bars, the concrete filled circular steel tube core columns are fixed in a longitudinally and horizontally crossing type rebar lattice, the reinforcing meshes are coated with concrete, the upper side and the lower side of each steel tube stretch out of the outer concrete by 150 mm -200 mm to facilitate the connection between an upper shear wall sheet and a lower shear wall sheet in the later stage, and connecting bars are reserved on the left side of the wall and on the right side of the wall and stretch out of the outer concrete by 200 mm - 300 mm to facilitate the connection between a left shear wall sheet and a right shear wall sheet in the later stage. Compared with conventional reinforced concrete shear walls, the concrete filled steel tube core column stiffening shear wall has the advantages of being higher in bending resistance, shearing resistance, hysteretic energy dissipation capacity and seismic resistance. Meanwhile, the shear wall is prefabricated in a factory and assembled on site in a cup joint mode, the construction technology is simple, the overall quality of a building can be guaranteed, production efficiency is greatly improved, and labor intensity is relieved.

Description

technical field [0001] The invention discloses a method for manufacturing and assembling a prefabricated steel pipe concrete core column stiffened shear wall, in particular to a method for prefabricating an anti-seismic shear wall in a factory and assembling it on site, and belongs to the technical field of construction engineering. technical background [0002] Today, with the rapid development of the construction industry, higher construction requirements for low-carbon, green, environmental protection, and high efficiency are put forward for buildings. The industrialization of construction is an inevitable trend in the development of the construction industry. The concept is to split the building structure into several building components. It is prefabricated in the factory, transported to the site for assembly, thereby eliminating dust, noise and other environmental pollution on the construction site, improving production efficiency, saving a lot of labor costs, and build...

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 remained high, and the production efficiency is low, making it difficult to meet the needs of automated table formwork production of shear walls

At present, a large number of anti-seismic shear reinforcements between the upper and lower wall pieces of conventional prefabricated reinforced concrete shear walls in the industry need to be connected, and steel sleeves and grout anchors are often used to connect. Conducive to earthquake resistance
