Abstract (en)
[origin: US5901504A] PCT No. PCT/EP96/02558 Sec. 371 Date Mar. 10, 1997 Sec. 102(e) Date Mar. 10, 1997 PCT Filed Jun. 13, 1996 PCT Pub. No. WO97/03265 PCT Pub. Date Jan. 30, 1991A roof for a built structure is proposed, which is designed in the form of a hollow body structure. It possesses interconnected walls (18 and 19) of flexible and at least substantially air-impermeable material. These walls (18 and 19) constitute elongated chambers (22), which are arranged side by side in sequence and are alternatingly designed as vacuum chambers (24) and gage pressure chambers (23). It is in this manner that an extremely strong, free span roof is created.
