Abstract

This invention relates to a construction method for a precise pre-embedded structure of a steel mesh shell basin-type bottom support for curtain walls. The method involves reinforcing the formwork with supporting steel sections and tie bars, and sealing it with sealant. Compared to traditional techniques, this method offers better formwork splicing and effectively reduces concrete grout leakage. The ring beam reinforcement moving and binding frame used is more convenient and faster for reinforcement placement and binding than existing technologies, significantly improving construction efficiency. Furthermore, after binding, the fixed frame can be moved away using a positioning horizontal reinforcement moving control device, facilitating the hoisting of the finished reinforcement frame. This reduces the number of auxiliary personnel required for hoisting and lowers the risk of collisions with the frame during hoisting, preventing frame deformation. A temporary adjustment and stabilization system for the bottom support suspension allows for adjustment of the embedded parts during hoisting, preventing the embedded parts from tipping over due to excessive tilting angles.
