AI Technical Summary
Technical Problem
The through-holes reserved in the precast exterior wall need to be filled later. Improper filling will cause thermal bridges, reduce the thermal insulation performance, and the installation efficiency of the external bracket is low.
Method used
The system employs support legs, hook mechanisms, and locking mechanisms. The hook mechanism locks the support legs to the precast exterior wall, and the locking mechanism drives the hook mechanism to lock or release the support legs from the precast exterior wall, thereby fixing the support legs and preventing the formation of through-holes.
Benefits of technology
It avoids the risks of thermal bridging and leakage, improves installation efficiency and safety, reduces workload, and enhances project quality.

Abstract
The application discloses a through-hole-free external hanging frame fixing device and fixing method, and relates to the technical field of building engineering. The fixing device comprises support legs, at least two hooking mechanisms and a locking mechanism. Each of the hooking mechanisms is vertically arranged on the support leg and is used for locking with a prefabricated outer wall to fix the support leg to the prefabricated outer wall. The locking mechanism is arranged on the support leg and is used for driving a vertical row of hooking mechanisms to lock with or release the prefabricated outer wall. In the application, a non-through matching groove is reserved, so that even if the late filling process is poor, a thermal bridge cannot be generated, and the risk of leakage cannot be generated, and the engineering quality is improved. Through the arrangement of the hooking mechanism and the locking mechanism, the support leg and the prefabricated outer wall can be fixedly connected or detached very conveniently, and a plurality of bolts and nuts are not needed to be matched to fix the prefabricated outer wall one by one, so that the workload of workers is reduced, and the work efficiency is improved.
