Embodiment
[0020] The cross-cable net inflatable membrane structure is arranged along the geodesic line, and its structure is as follows figure 1 As shown, the structure includes an inflatable membrane 1 and a cable 2 . Among them, the middle part of the inflatable film 1 is a cylinder after being inflated and formed, and the two ends are arc-shaped peripheral film surfaces with a smooth transition. The curvature of the peripheral film surface formed by the inflatable film 1 is a positive Gaussian curvature. Several entrances and exits 11 are arranged in the long side direction of the membrane surface, wherein the revolving door is the main entrance and exit, and the closed door is temporarily used as a safety door. The cable 2 starts from the anchor points at both ends and is arranged on the peripheral membrane surface along the geodesic direction, so that the lateral swing of the cable 2 can be minimized during normal use. The stay cables 2 forming a network structure are fixed on the...
