The joint member 9 is optimal because it can connect and fix the floor panel 6 more firmly.In addition, the cross-sectional shape of the joint member 9 may be, for example, a U-shaped cross-section as shown in FIG. 8A. For example, a material having an L-shaped cross section as shown in FIG. 8B (preferably reinforced with a stiffener 17), a material having an H-shaped cross section as shown in FIG.

Further, when the joint member 9 is brought into contact with and fixed to the connecting part 7, for example, as shown in the above embodiment,
Instead of tightening and fixing with the bolts 10 and nuts 11, they may be fixed by welding.

(Effects of the invention) As described above, the underground structure of the invention has a face plate stretched over a metal frame made of metal shapes to form a ceiling panel, a wall panel, and a floor panel. In an underground structure constructed by connecting and fixing a required number of panels and floor panels, the connecting portions of the adjacent ceiling panels, the connecting portions of the adjacent wall panels, and the adjacent ceiling panels and wall panels. One joint member made of a metal profile is brought into contact and fixed across all three joints of the joints, and the joints of the adjacent wall panels are connected to the joints of the adjacent floor panels. One joint member made of a metal profile is brought into contact with and fixed to all three joints of the wall panel and the adjacent wall panel and floor panel. In addition to being made of metal shapes that are resistant to bending and deformation, the ceiling panel, wall panel, and floor panel located at the connection part are all strongly fixed and integrated through the high-strength joint member. Since a strong joint block body is formed, there is no risk of the joints buckling due to underground earth pressure, water pressure, etc., and this is particularly effective for joints in the girder direction (longitudinal direction) that are prone to buckling. It is effective and there is no risk of meandering or deforming the walls of underground structures.
