Description

Technical Field

[0001] This utility model relates to the field of curtain wall construction technology, specifically to a fireproof sealing structure between curtain wall layers. Background Technology

[0002] In modern building curtain wall engineering, interlayer fire-stopping structures are crucial for ensuring fire safety. Their function is to prevent the spread of flames and high-temperature smoke, while also providing thermal insulation and soundproofing. However, as the industry's requirements for safety, environmental protection, and construction efficiency increase, the existing mainstream method of "galvanized iron sheet + fire-retardant adhesive" has revealed numerous problems. In terms of materials, commonly used silicone fire retardant adhesives are mostly oil-based, releasing a large amount of VOCs during curing and use, which pollutes the construction environment, affects the health of personnel, and reduces indoor air quality after the building is in use. They are not suitable for civil, medical and office buildings with high requirements for indoor environment. The construction process has significant drawbacks: galvanized steel sheets need to be custom-made to size, extending the preparation period and increasing costs; the on-site installation process is cumbersome, requiring the steel sheets to be cut and fixed before fireproofing adhesive is applied, demanding a high level of skill from the construction workers. Especially in complex areas such as curtain wall corners and irregularly shaped structures, it is difficult to ensure the fit of the steel sheets, and the fireproofing adhesive is easily missed or insufficiently applied, creating a potential problem of incomplete sealing. In terms of performance stability, existing structures are ill-suited to adapting to deformations caused by temperature changes, wind loads, and foundation settlement in curtain walls. Galvanized steel sheets are rigid but lack elasticity, and silicone fireproof adhesive ages and loses elasticity over time, leading to cracking and delamination of the sealing structure, resulting in failure of fire and smoke protection. Furthermore, its poor thermal insulation properties easily create thermal bridges, increasing energy consumption, and its poor sound insulation affects user comfort. In summary, existing methods have significant shortcomings in terms of material environmental friendliness, ease of construction, and performance stability, and there is an urgent need for new fireproof sealing structures to solve these problems.
