PROBLEM TO BE SOLVED: To improve the rigidity of a double air membrane structure against short term loading such as wind pressure, and to solve the problems peculiar to the double air membrane structure such as higher maintenance/administrative expenses for a blower or the like, and rupture phenomenon of a membrane, and necessity of reinforcement. SOLUTION: This double air membrane structure (1) is so constructed that a number of cores 4 are housed in a transmembrane area 5 of flexible membranes 2, 3. A suction pipe 7 communicates with the transmembrane area, and a suction means 8 sucks air in the transmembrane area. A sealing means 9 functions to keep the negative pressure of the transmembrane area. The transmembrane area is decompressed so that the core and the flexible membrane closely adhere to each other and the cores closely adhere to each other. The core is formed of an air sac obtained by enclosing gas in the flexible membrane. COPYRIGHT: (C)2008,JPO&INPIT
