Abstract:
A mounting metal fitting used for a flexible membrane inflating structural body which is erected by supplying a fluid to an interior of a flexible membrane and which is laid flat by discharging the fluid within the flexible membrane, said mounting metal fitting including a first metal fitting disposed at a side of a structure at which the flexible membrane inflating structural body is provided and contacting one surface of the flexible membrane, and further including a second metal fitting contacting another surface of the flexible membrane, and together with the first metal fitting, sandwiching a portion of the flexible membrane in the vicinity of an outer peripheral edge thereof by a fixing means,wherein at least one convex portion is provided in each of the first and second metal fittings so as to bend the flexible membrane while the flexible membrane is being held, andcorner portions of an end portion of the convex portion are chamfered so as to form a radius of curvature, and respective radii of curvature of the chamfered corner portions are set so as to be gradually made smaller toward an outer end of the first and second meta fittings in the direction of the outer peripheral edge of the flexible membrane.
