AI Technical Summary
Precast bay window covers are not as integral as traditional cast-in-place structures in terms of connection. Over time, this may lead to loosening of the connections, affecting the stability and durability of the cover.
Several sets of longitudinal steel bars are pre-embedded inside the wall and symmetrically arranged. They are connected by lap joints with support beams and transverse steel bars. Concrete is then poured to enhance the bond between the steel bars. Additional constraints are provided by welding the sleeves to the longitudinal steel bars. A lifting mechanism is set under the precast cover plate to improve stability and convenience.
It significantly improves the load-bearing capacity, stability and durability of precast cover plates, prevents steel bar buckling or misalignment, and enhances the overall structural stability and ease of construction.
