AI Technical Summary
The sealant at the joints of traditional prefabricated exterior walls is prone to aging and cracking, resulting in reduced sealing performance and inconvenient maintenance.
It adopts a sliding structure of mounting bracket and connecting bracket, and the design of glue injection port and glue outlet allows for repeated replenishment of sealant. Combined with the elastic design of rubber pad, it can adapt to walls of different thicknesses and maintain sealing.
It increases the service life of the sealant, reduces maintenance costs, enhances waterproof performance, adapts to wall deformation, and prevents the sealant layer from cracking.
