When the connecting hole 31 is arranged as a strip through hole, the position of the steel structure beam can be fine-tuned on the connecting plate 3.

[0029] refer to Figure 1 , Figure 4 , Figure 5 The connecting plate 3 and the steel structure beam 5 are detachably connected by bolts, which can ensure the stability of the connection between the connecting plate 3 and the steel structure beam 5.
