| 摘要 |
The invention concerns inflatable roof elements (1) comprising two air-filled layered flexible films (2, 3) and tightening ropes (4,5) associated with said films, resting on a support structure capable of supporting at least two juxtaposed roof elements (1) and designed to cover a specific volume for agricultural, horticultural, sporting purposes or the like. Said elements are essentially characterised in that the layered flexible films (2, 3) belong to a common closed sleeve, the tightening ropes (4, 5) are longitudinally positioned inside the sleeve and placed inside sheaths (9, 10) obtained by linear longitudinal welding of the two layered films (2, 3) of the sleeve at the rate of one weld seam (11) for the end sheaths (9) and two weld seams (12) for the intermediate sheaths (10). |
