Description

Technical Field

[0001] The utility model belongs to the technical field of curtain wall panel installation, in particular to a plug-in installation structure for narrow-slot metal curtain walls. Background Art

[0002] In curtain wall decoration projects, metal curtain wall systems have become the main curtain wall form for many high-rise buildings besides glass curtain walls. The gaps between metal curtain wall panels are generally filled with weather-resistant sealant, and the width of the sealant is about 15mm.

[0003] The following problems generally occur after sealant construction:

[0004] 1. The sealant is too wide and affects the facade effect of the building plan.

[0005] 2. The workers' proficiency in applying glue cannot be guaranteed, which contaminates the surface layer of the curtain wall panels, making it difficult to grasp the quality of the overall construction.

[0006] In addition to applying sealant, metal curtain wall panels can also be treated in an open manner, with several more waterproof backboards added on the back of the panels. However, this method will cause the overall thickness of the curtain wall to become thicker and more bloated, making the curtain wall construction complicated and resulting in low construction efficiency.

[0007] Based on the above problems, a new type of narrow-slit metal curtain wall installation structure is urgently needed. Utility Model Content
