AI Technical Summary
Existing prefabricated concrete shear walls suffer from problems such as unstable connection joint quality, low installation efficiency, and difficulty in ensuring construction quality in terms of the reliable connection of prefabricated components. In particular, the transportation and installation costs are high due to the large volume and heavy weight of prefabricated components, and the wet connection method has weak joints.
A precast steel reinforcement cage is used, and vertical and horizontal steel reinforcement joints are connected by mechanical sleeves. The mechanical sleeves are arranged in an alternating manner to improve the reliability of the connection. After the steel reinforcement cage is precast in the factory, concrete is poured on site to ensure the connection quality and integrity.
It reduced factory mold-making and transportation costs, improved construction quality and installation reliability, achieved standardized and large-scale production, reduced construction difficulty and costs, and ensured the integrity and seismic performance of the structure.
