    • PROBLEM TO BE SOLVED: To provide a large opening part by forming the opening part in arch structure, arranging a beam below the opening part forming an arch and arranging a support by connecting a supporting point in the neighbourhood of both ends of the arch opening part and the beam to each other by a hanging cable. SOLUTION: One end of a hanging cable 6 is fixed in the neighbourhood of a supporting point 4 of an arch 3 of an opening part 2, the other end of the hanging cable 6 is fixed on a beam 5, and the supporting point 4 and the beam 5 are connected to each other by the hanging cable 6. Thereafter, when each of the hanging cables 6 on both sides is arranged in the diagonal direction by directing each of them toward inside, force to enter inside is generated on an end part of the arch 3 through the cables 6, and a closed tensile force field is formed by the arch 3 of the opening part 2, the hanging cables 6 and the beam 5. Additionally, a support 7 is arranged roughly in the vertical direction between the beam 5 and the arch 3 of the opening part 2, a lower end of the support 7 is installed on the beam 5 and an upper end of the support 7 is fixed on the arch 3 from below. Consequently, it is possible to control large stress and displacement of the arch in the optimal state by introduction of prestress.

    • PROBLEM TO BE SOLVED: To reduce thrust transmission by fixing a lower end of a curved roof frame a center of which is formed high on a vertical support member, connecting upper and lower ends of the support member by overhanging a horizontal material at an intermediate position of this support member and pin-connecting leg parts of the support member. SOLUTION: Both lower ends of a curved roof frame 1 are fixed on vertical support members 2, ends of upper chord 11 of a truss are fixed on upper ends of the support members 2 and ends of lower chord 12 are fixed on intermediate parts of the support members 2. Thereafter, horizontal materials 3 are overhung to outsides of intermediate positions of the support members 2, and the truss is formed by connecting head ends of these horizontal materials 3 and upper and lower ends of the support members 2 to each other by diagonal member 4. Thereafter, the leg parts of the support members 2 which are vertically set are connected to lower part supports 5 with pins 51, and the lower part supports 5 arranged on a curve are connected and constrained by support tie beams 6 in the circumferential direction. Consequently, it is possible to reduce transmission of thrust to a lower part structure by roof dead weight in simple structure.

    • PROBLEM TO BE SOLVED: To provide a film body connecting structure which is enhanced in cutoff performance, and improved in adhesiveness between a waterproof sheet film body having a fluororesin on its surface and a cutoff sheet, to thereby improve the water- tightness and air-tightness thereof. SOLUTION: The film body connecting structure for use in an air dome is formed by rigidly pinching a joint portion of the film bodies A with plates serially arranged in a film body connecting direction, and an upper member 6, and covering the same with a gasket G. Then, the cutoff sheet B is fixed to a boundary portion between the gasket G and the film body A so as to cover the same. At this time, a primer (a) is applied to an adherend surface of the waterproof sheet film body A having the fluororesin. The primer is a solution at solid content concentration of 3 to 25%, and contains a bromide of isobutylene-p-methyl styrene copolymer or a blended material of the bromide and a natural or synthetic rubber, as a main ingredient, and an aliphatic hydrocarbon-based solvent as a solvent main ingredient. Thereafter, the cutoff sheet B is fixed to the film body A via an adhesive (b) in the form of a natural vulcanized tape, containing butyl rubber having autohesion properties at room temperature.
