生じやすいという問題があった。However, in such a conventional device, as shown in FIG. 3, when an airtight load is applied to the structure, as in the case where a vehicle travels in a tunnel, the outer plate 56 and the bridge are connected to each other. A compressive or tensile load acts on a straight line L1 connecting the connection nodes 62 with the member 60. Similarly, a compressive or tensile load acts on a straight line L2 connecting between the joint nodes 64 between the inner plate 58 and the bridge member 60. Therefore, since the outer plate 56 and the inner plate 58 are curved, there is a problem that the load on the straight lines L1 and L2 easily causes out-of-plane deformation.
