Membrane structure and membrane structure textiles

 

Development of membrane structure and the development of the textile industry are closely related. Concave century due to the development of chemical fiber industry and the glass industry, expanding the application fields of textile industry. Due to the high number of glass fiber and synthetic fiber having a strength, hydrophobicity and good resistance to corrosion and fungus, with its woven into the fabric and then after an appropriate polymer coating and post-processing. Can further improve its performance and features, it can be widely used in some large building roof. This specially treated textile materials, commonly known as the membrane structure of textile material or film material. Largest membrane structure - Sha Teji large airport terminal, the construction area of ​​420,000 square meters.

Building using textile materials roofing membrane structure has many advantages. Coated fabrics compared with brick, tile, cement, steel and other traditional materials. Much lighter weight. Membrane structure of the roof material, the weight of traditional building materials and only made 1/30. Thus, membrane structure greatly reduce the support structure and reinforcing materials, reduce the cost. In addition, it can be applied to the construction of large-span buildings, span the world's largest membrane structure building can reach 200 meters, which is brick, cement and other traditional buildings can not be achieved. Thus, membrane structure for the construction of large public spaces, equipment warehouse, materials warehouse, exhibition halls, stadiums, airport waiting room is particularly applicable, has become one of the preferred targets of these buildings. In addition, the membrane structure can be used as film material having transparency in the daytime lighting electricity savings: building materials, membrane structures can better withstand earthquakes and other destructive power. Compared with conventional structural materials, fabric roof constructed of relatively lightweight, it is easy to take down the set elsewhere: when the fabric is worn, repair is also very convenient. Roof membrane structure using materials that can provide the conditions for the realization of imaginative architects, urban beautification purposes.

International began in the late 1970s - early 1960s, membrane structure buildings, has been used for 30 years, currently intact. This shows that the life of the fabric membrane structure may be more than three years, which can meet the requirements for those with lower permanent building construction requirements, you can use poorer quality membrane materials, which can reach 15 years of service life -20 years. That meets the requirement of a semi-permanent building. Membrane structure the world has become a fashion, especially the Olympic Games field, Expo Hall et al type buildings. Have extensive use of membrane structure, its practicality, economy, aesthetics have been fully reflected. For decades, and its more extensive applications, the speed of development is also growing fast.
