Abstract
A flexible membrane inflating structural body is fixed to a structure such as a bed and slope sides of a waterway by using a mounting metal fitting comprising a first metal fitting and a second metal fitting. The flexible membrane inflating structural body is erected by supplying a fluid to an interior of a flexible membrane, and is deflated by discharging the fluid within the flexible membrane. The first metal fitting is disposed at a side of the structure at which the flexible membrane inflating structural body is provided and contacts one surface of the flexible membrane. The second metal fitting contacts another surface of the flexible membrane and, together with the first metal fitting, sandwiches a portion of the flexible membrane in a vicinity of an outer peripheral edge of the flexible membrane. The first and second metal fittings, which form the mounting metal fitting, each include at least one convex portion which bends the flexible membrane while the flexible membrane is in a held state. Corner portions of each convex portion of the mounting metal fitting are each 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 the outer peripheral edge of the flexible membrane.
