Both ends of the connecting plate in the height direction D1 of the corner structure 100 are connected to the base plate 110 and the mounting plate 120, respectively. The plurality of connection plates may be different in shape from one another. Specifically, both ends of the connecting plate in the height direction D1 of the corner structure 100 are connected to the base plate 110 and the mounting plate 120, respectively, by welding. A plurality of connecting panels may be arranged along the length direction D2 of the corner structure 100. The adjacent connecting plates can be connected together by welding. This can improve the structural strength of the corner structure 100.

The outer surface 135 of the first web 131 is flush with the outer surface 136 of the third web 133 along the length direction D2 of the corner structure 100. Thereby, the third connecting plate 133 can provide sufficient support strength, and the structural strength of the corner structure 100 in the length direction D2 of the corner structure 100 is enhanced, without affecting the installation of the corner structure 100.

The mounting plate 120 further has coupling holes 121 and positioning holes 122, and the coupling holes 121 and the positioning holes 122 are arranged at intervals along the length direction D2 of the corner structure 100.
