建筑膜材及气膜结构性能特点与应用现状

Performance feature and application status of building membrane material and gas film structure

气膜结构已越来越广泛地应用于大跨度建筑中,但目前建筑膜材及气膜结构防火性能的研究匮乏,在一定程度上已经影响到我国膜材、膜结构行业的发展。介绍了建筑膜材的种类、特性,提出不同膜材的应用选择。再从某建筑膜材防火检验出发,通过燃烧特性试验分析火灾危险性,并结合建筑实际开展大尺度点燃性试验,了解其整体防火性能,然后阐述气膜结构性能特点和优势。介绍了气膜结构主要用途以及防火性能方面的应用案例。

Gas film structure has been more and more widely used in the large span construction, but currently the scanty re- searches of fireproof performance on building membrane material and gas film had affected the development of our country＇s mem- brane material and membrane structure industry to a certain extent. This paper introduced type and characteristic of building mem- brane material,and presented application selection on different membrane material. Then starting from an architectural membrane ma- terial fire inspection,analyzed the fire risk by combustion characteristic test, combined with construction theory to carry out large scale fire test,realized their overall fireproof performance,then set forth the performance features and advantages of gas film structure. This paper introduced main application of gas film structure and application cases on fireproof performance in detail.
