Description

Technical Field

[0001] The utility model relates to the technical field of inflatable membranes, in particular to an inflatable membrane leakage-proof structure. Background Art

[0002] Inflatable membrane structures come in three forms: single-layer, double-layer, and air-ribbed. They generally require a long-term, uninterrupted energy supply. Single-layer inflatable membrane structures in low-arch, long-span buildings must be enclosed spaces and maintain a certain indoor-outdoor pressure differential. Common inflatable membranes include ETFE membranes, a material used in membrane structure engineering. ETFE was used in the National Indoor Stadium and the National Aquatics Center at the 2008 Beijing Olympics.

[0003] In the existing technical solutions, during the use of the internal leak-proof inflatable membrane, too many bolts are usually required to fix the inflatable membrane body, which is very inconvenient for disassembly and assembly. On rainy days, rainwater leakage is prone to occur at the connection between the inflatable membrane material and the steel structure, which greatly reduces the waterproof performance of the house structure using the inflatable membrane material and affects normal daily use.
