FIELD: construction, particular, transformed inflatable structures used for temporary covering of structures of large sizes. SUBSTANCE: transformed inflatable vault is formed by connection of many separate hollow inflatable beams installed tightly with one another. Inflatable beam is formed of flexible shell and joined with adjacent beams with help of discrete means of quick joining and installed separately with the aid of single for all beams air supplying pipeline. Each hollow beam is made with two holes located opposite to each other and provided with temporary tight means forming supply pipeline. Flexible shell has four longitudinal panels whose surfaces are dissected along four longitudinal ribs and interconnected by means of discrete mechanical means of quick joining and has means ensuring constant airtight volume of shell. EFFECT: higher efficiency. 11 cl, 21 dwg
