玻璃幕墙开启扇多腔密封结构设计

Design of multi-cavity sealing structure for opening window of glass curtain wall

幕墙水密性能是关系到幕墙能否正常使用的一个重要指标.建筑玻璃幕墙开启扇普遍采用2道三元乙丙橡胶胶条形成等压腔密封,在极端恶劣条件下开启扇易发生雨水渗漏,影响玻璃幕墙的正常使用.为解决此问题,通过对开启扇密封结构的优化设计,采用多腔密封结构,有效提高了开启扇的密封性能,保证了玻璃幕墙的正常使用.

The watertightness of curtain wall is an important index related to whether curtain wall can be used normally. Two EPDM rubber strips are commonly used to form an equal pressure chamber seal for the opening window of building glass curtain wall. Rainwater leakage is easy to occur in the opening window under extreme conditions, which affects the normal use of glass curtain wall. In order to solve this problem, the multi-cavity sealing structure is adopted by optimizing the sealing structure of the opening window, which effectively improves the sealing performance of the opening window and ensures the normal use of the glass curtain wall.
