专利汇可以提供Inflatable shelter and method of erection专利检索，专利查询，专利分析的服务。并且A lightweight flexible inflatable shelter for enclosing large areas in applications such as greenhouses, warehouses, recreation areas and other large enclosures, and in various methods of air and water pollution control. The shelter has an envelope of lightweight, low-modulus sheet material such as stretchable fabric or plastic film having high elongation properties. The sheet material is restrained by a cable grid system having heavyduty, longitudinal parallel cables running in one direction and lighter parallel cables running transversely across the longitudinal cables. The cable grid system is tethered to restraint cables or masts at spaced points throughout the structure to restrain the grid system and the sheet material at predetermined elevations from the ground and cause the building, when inflated, to form a plurality of substantially identical dome-shaped roof sections, with the cable grid system and the tether restraint means uniformly distributing stresses throughout the structure. The shelter may be completely assembled on the site by erecting a series of perpendicular masts, draping the cable grid system across the tops of the masts, attaching long strips of sheet material between the rows of draped cables, anchoring the ends of the cables and the sheet material to the ground and inducing internal inflation pressure into the assembled structure.，下面是Inflatable shelter and method of erection专利的具体信息内容。
