The two hanging boxes 1 are respectively arranged on the opposite sides at the splicing position of the two adjacent upper and lower steel columns 3. The upper box opening of the hanging box 1 is arranged below the splicing position. The hanging ear plates 11 are detachably installed on the connecting ear plates 31 at the splicing position of the two steel columns 3. Notches are respectively formed at both ends of the opposite sides of the two hanging boxes 1. The two notches of the hanging box 1 are respectively arranged on the opposite sides of the steel column 3.

[0031] The number of overlapping plates 2 is two. An overlapping plate 2 is connected between the two notches corresponding to the positions of the two hanging boxes 1. The position of the overlapping plate corresponds to the position of the ladder 31 on the steel column.

[0032] The fireproof cloth 4 covers the outer wall of the hanging box 1.

[0033] As a preferred embodiment, the hanging box 1 includes: a bottom plate 12, a column 13, and a guardrail 14.

[0034] In this embodiment, the bottom plate 12 is rectangular. The bottom plate 12 has a first side close to the steel column 3 and a second side far from the steel column 3.

[0035] The number of columns 13 is two. Two columns 13 are vertically arranged on the first side of the bottom plate 12 and are oppositely arranged. The upper ends of the columns 13 are connected to the hanging ear plates 11.

[0036] Guardrails 14 are provided at both ends of the bottom plate 12 and on the second side of the bottom plate 12. A notch is formed between the column 13 and the guardrail 14 at the end of the bottom plate 12.

[0037] In this embodiment, the bottom plate includes a support frame and a platform plate. The support frame is a planar frame. The platform plate is laid on the support frame. A hook is installed on one side of the support frame. The bottom plate is hung on the lower ends of the columns through the hook. When installing the hanging box, first install the columns on the steel columns, and then install the bottom plate on the columns.

[0038] One end of the overlapping plate 2 slides on the bottom plate 12 of a hanging box 1. The other end of the overlapping plate 2 is rotatably connected with a hook 21.
