[0002] As a decorative maintenance structure, the curtain wall's support is mainly connected to the main structure's pre-embedded or post-installed embedded parts through adapters. Due to the frequent misalignment of the pre-embedded plates during the main structure's pouring, coupled with the owner's requests for adjustments and changes to the plan during curtain wall construction, the utilization rate of pre-embedded parts is low, often requiring the use of post-installed embedded parts for correction. However, the welding workload between post-installed embedded parts and connecting parts is large, which not only easily induces fires but also has a significant impact on quality due to welding stress, while also reducing construction efficiency.

[0003] The existing connection structure between curtain wall connectors and embedded parts has the following defects:

[0004] Existing curtain wall connectors require welding to connect to embedded parts. The welding process is prone to fire accidents and produces harmful gases such as carbon monoxide, nitrogen oxides, and ozone, which not only pollute the environment but also cause occupational injuries to workers. In addition, it is difficult to control quality and has low construction efficiency.

[0005] Therefore, a solution is needed. Utility Model Content
