As shown in FIG. 26 of No. 9573, the film material is fixed or fixed at a predetermined height on the upper chord material, and the film material is supported or fixed on a receiving member for supporting the film material while applying tension to the film material. Therefore, in addition to the axial force transmitted to the upper chord material and the axial force coming from the diagonal material, the tension of the film material supported by the receiving member acts eccentrically on the upper chord material, and the bending moment and the twist due to the eccentricity act on the upper chord material. In order to bear the bending moment, it is necessary to have a cross-sectional dimension that is strong enough to resist the bending moment. Further, when the upper chord material is not enlarged to secure the strength, a frame for supporting or fixing the film material may be assembled on the upper chord material.

造物。1. A truss frame member formed by connecting an upper chord material and a lower chord material via a bundle material and an abdominal material is arranged in parallel at intervals with a height lower than the height of the upper chord material between the truss frame materials. The truss frame material is arranged in parallel with the truss frame material, the truss frame materials are connected to each other by a joining material at a lower node portion of the bundle material, and the upper and lower nodes of the truss frame material bundle and the through member are connected. The truss frame member is connected by a connecting member provided on a surface orthogonal to the truss frame member, and the joint position of the upper chord or the lower chord to which the abdominal member of the truss frame member is joined is also connected by the connecting member. A membrane structure characterized in that a shaped steel or pipe member having a flange is used for the upper chord member and the through member, and a membrane material is stretched on the upper surface of the shaped steel or pipe member.
