Figure 1: is a schematic diagram of the end surface structure of the first metal profiled plate 1 and the second metal profiled plate 2. The first metal profiled plate 1 and the second metal profiled plate 2 are shaped as plates extending in the shape of the end surfaces, wherein the first metal profiled plate 1 and the second metal profiled plate 2 are respectively provided with a first mother opening 11 and a first sub-opening 21, and the first sub-opening 21 and the first mother opening 11 are bite edge lock seam type structures. Specifically, a first B-shaped bend 12 is provided on one side of the first metal profiled plate 1. Figure 1 The first B-shaped bend 12 is a structure that is arranged in the opposite direction of the "B" character. The first female opening 11 is located at the inward bending of the first B-shaped bend 12. The first female opening 11 is an open structure, which is bent inward on one side of the second metal corrugated plate 2 to form a first sub-opening 21.
