格別の効果が得られたのである。(Effects of the Invention) In contrast to the above-mentioned birch, the present invention forms a strung beam structure by stretching a plurality of cables over a plurality of support rods protruding from a 7-ch-shaped support frame. To form such a strung beam structure, it is only necessary to stretch lightweight cables on support rods, so the construction work is not complicated and is extremely simple, unlike conventional structures in which a truss-like frame is formed from steel members. Not only was it faster and faster, and work could be done safely at heights, but it also had the extraordinary effect of being able to significantly reduce costs.

構成できるという特有の効果を奏することとなる。Furthermore, when a holding cable is strung over the membrane material stretched over the stretched string beam structure, the holding cable causes various bulges of the membrane material that is pressurized from inside and bulges outward. Therefore, by arbitrarily changing the tensioning position of the holding cable and arbitrarily adjusting its tension, a dome roof having a desired external appearance can be constructed, which is a unique effect. That will happen.
