ETFE膜结构屋面防水构造及质量控制研究

Study on Waterproof Structure and Quality Control of ETFE Membrane Structure Roof

膜结构防水构造及安装质量是影响建筑功能和耐久性的关键因素。通常,对于大面积单层ETFE膜屋面结构,根据一定规律将其分割成多个ETFE膜结构单元,然后安装在钢结构或索结构体系上,充分保证各个ETFE膜结构单元的防水构造及安装质量,以减少ETFE膜屋面渗漏。论文以厦门白鹭体育场ETFE膜结构屋面为例,对索承式单层ETFE膜屋面结构防水构造设计及安装质量控制进行研究,总结索承式ETFE膜结构防水技术质量控制要点。

The waterproof structure and installation quality of membrane structure are the key factors affecting the function and durability of buildings.Generally,for the large-area single-layer ETFE membrane roof structure,it is divided into multiple ETFE membrane structural units according to certain laws,and then installed on the steel structure or cable structure system,and fully ensure the waterproof structure and installation quality of each ETFE membrane structural unit to reduce leakage.Taking the ETFE membrane structure roof of Xiamen Bailu Stadium as an example,this paper studies the waterproof structure design and installation quality control of cable-supported single-layer ETFE membrane roof structure,and summarizes the key points of waterproof technology quality control of cable-supported ETFE membrane structure.
