摘　　要：随着隐框玻璃幕墙使用年限的累积,连接玻璃面板与副框的结构胶性能逐渐劣化,直接影响幕墙安全与使用寿命。现有研究中,针对结构胶的老化设备研究对象以小型的试件为主,不能用于足尺玻璃幕墙单元整体的老化研究。本文设计了一种易装配性的隐框玻璃幕墙结构胶加速老化设备,能够对隐框玻璃幕墙进行紫外与热耦合条件下的老化试验,为研究隐框玻璃幕墙结构胶的性能奠定了基础。With the long-term use of hidden frame glass curtain wall,the structural adhesive,connecting glass panel and auxiliary frame,deteriorates gradually.This directly af fects the safety and service life of the hidden frame glass curtain wall.Currently,the equipment to accelerate the aging of structural adhesive is mainly used for small specimens,and it cannot be used for the aging of full-scale glass curtain wall.In this paper,an accelerated aging equipment for structural sealant is designed,which is easy to install,assemble and disassemble.The designed equipment can be used for aging test of full-scale glass curtain wall under the condition of ultraviolet radiation and thermal coupling environment.This lay a foundation for the research of the performance evolution of structural silicone sealant.
