Background technique

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. the

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 always been high, and the production efficiency is low, making it difficult to supply the demand for automated table formwork production of shear wall pieces. Therefore, there is a need for a prefabricated shear wall that is simple to manufacture, fast in factory production and easy to assemble on site, and its shear resistance is not weaker than that of ordinary reinforced concrete shear walls, thereby improving the efficiency of factory prefabricated production. the

The diameter of the circular concrete-filled steel tube core column 1 is 100-200mm, and the distance between the circular steel tube concrete core columns 1 is 6-10 times the diameter of the circular steel tube concrete core column. the

The upper and lower ends of the circular concrete-filled steel tube core column 1 protrude from the outsourcing concrete by 50-200mm, and the reserved connecting bars protrude from the outsourcing concrete by 100-500mm to the left and right sides. the

The concrete-filled steel tube core column is embedded in the ordinary reinforced concrete shear wall to replace a part of the vertical shear reinforcement, and the high bearing capacity and high ductility of the steel tube concrete are used to effectively improve the compressive bearing capacity and shear bearing capacity of the shear wall , has good shock resistance, etc. The utility model is prefabricated in a factory, and the shear wall units only need to be assembled on site during application. the

The beneficial effects of the utility model are: the construction process of the components of the utility model is simple, and the production labor is small. Through factory prefabrication and on-site assembly, the overall quality of the building can be guaranteed, the construction operation speed can be improved, and the labor operation intensity can be reduced. the
