随着ETFE(Ethylene Tetra Fluro Ethylene)膜材的成功研发,凭借其轻质、透光、隔热、抗腐、耐候、自洁等良好的性能而被广泛应用,大量的学者也对其开展研究。ETFE膜材为非织物类膜材,相比织物类膜材其单张膜的抗拉强度较低,常采用气枕的形式多张共同受力,并通过内压使其具有合适的刚度,由此产生的气枕式膜结构具有较好的力学性能和使用性能,逐渐得到广泛的发展并具有良好的前景。提炼出了ETFE气枕式膜结构相比于其它膜结构独有的可调节特性,在服役过程中通过内压改变对受力性能、透光率、隔热性能等的自动调节能力,并对ETFE气枕式膜结构的发展、性能、设计方法与施工技术进行研究与归纳,总结了国内外学者对ETFE气枕式膜结构的研究现状,对工程实践具有一定的指导意义。
With the successful development of ETFE (Ethylene Tetra Fluro Ethylene) membrane, it has been widely used by many scholars due to its good properties of light weight, light transmission, heat insulation, corrosion resistance, weather resistance and self-cleaning. . ETFE film is a non-woven fabric film, compared with fabric-like film sheet tensile strength is low, often in the form of a plurality of common pillow and by internal pressure so that it has the appropriate stiffness, The resulting pillow-type membrane structure has good mechanical properties and performance, has been widely developed and has good prospects. The ETFE Pillow-type membrane structure is compared with other membrane structure unique adjustable characteristics, through the internal pressure in the process of changing the force performance, light transmittance, thermal insulation properties such as the ability to automatically adjust, and ETFE Pillow-type membrane structure development, performance, design methods and construction techniques to study and summarize the domestic and foreign scholars on the ETFE Pillow-type membrane structure of the research status of engineering practice has a certain significance.
