[0016] The technical solutions of the present invention will be further described below with reference to the accompanying drawings.
[0017] figure 1 The plan elevation view of the integrally stretched beam of the air-filled film of the present invention is given. like figure 1 As shown, the integral tension beam of the inflatable membrane includes an air bearing elastic plate 1, a spindle-shaped inflatable membrane 2, and a helical tension cable 3, which constitute the main structural components of the inflatable tension integral membrane structure. The air-bearing elastic plate 1 (upper curvature radius R1) with span L and width b is fixed on the spindle-shaped inflatable membrane 2 through the spiral tension cable 3 (A-C-B', A'-C-B), and inside the spindle-shaped inflatable membrane 2 Air 5 (150-250 mBar greater than atmospheric pressure) is pumped in by a blower, and a hinged connection point 4 is fixed at each end of the air-bearing elastic plate 1 .
