China and Germany have been for more than 100 clients solve cesspool stamped, servo technologies lead the industry! What is a large span of Film Film large span building construction is the use of gas as the main membrane structure building systems. Gas membrane structure as a large span structures, using a high-strength flexible film material support membrane to cover a large span space using air pressure. The principle is: the membrane is fixed to the ground surrounding infrastructure, the use of air supply systems for indoor air pressure rises to a certain pressure, so that a pressure difference inside and outside the roof to resist external force, due to the use of air pressure to support, without any beam, columns, so get more complete clearance of building space. After 60 years of development, large span gas membrane construction has formed a complete theoretical system and technical standards. (B) with respect to the gas membrane building advantages of traditional building structure: ● light construction space larger membrane span due to very light weight, the weight of three kilograms per square meter or less. No internal pressure to support the use of beams, columns, it is possible to easily achieve more than 100 meters long span clearance space, the maximum span of 150 meters, which is the traditional structures can not be done. Due to the special structure of membrane structure works. Cause under wind loads, the main force for the rising force. Even in the roof and floor, does not give the original building to increase the load-bearing. Expanded the scope of the construction of sports venues, the effective use of existing building area. ● Lower construction costs and low cost construction membranes, bilayers approximately 30% lower than the price of a traditional lightweight construction composite insulation board, but higher than the monolayer only about 30%. Because building roof membrane and weighs only conventional steel roof of 1/30, which at the same time reducing the cost of the wall and foundation. www.zdmjg.com www.szjrt.com.cn www.szjrt1.com
