China and Germany have completed 36 major sports stadiums, exhibition halls, structural design and construction of the museum film! Structural design principles of a diaphragm connection between the diaphragm can be hot fusion, stitching or mechanical connections, as shown below: Second, the strength of the diaphragm membrane junction, by production unit process guarantee. When the project needs, by experimental verification. Third, the seams between the position of the diaphragm and the diaphragm should be based on building requirements, structural requirements, and other factors to determine the economic demands. Fourth, the stitching lines membrane surface membrane should be reasonably arranged according to the direction of the main force Jingwei, should adopt the zonal stitching, the stitching and stitching three methods to the tree. Five roofing membrane should lap, lap joints should consider water requirements, see below: six, the number of joints should be less. Seams and stress concentration near the site may produce enhanced diagonal slices suitably strengthened. Avoid cross and overlap seams. Seven, the main force on the membrane surface seam stitching heat fusion methods should be used to connect. www.zdmjg.com www.szjrt.com.cn www.szjrt1.com
