For example, a quickly assembled steel structure elevator shaft for adding an elevator with the publication number of CN211775447U includes three steel structure shaft units with the same structure, which are hoisted successively from bottom to top. The steel structure shaft unit includes U-shaped steel columns, steel beam structures, tempered glass plates and stainless steel bending parts. The U-shaped steel columns include the first U-shaped steel column, the second U-shaped steel column, the third U-shaped steel column and the fourth U-shaped steel column. Six steel beam structures are arranged in parallel at equal intervals on the U-shaped steel columns. The steel beam structure includes the first U-shaped steel beam, the second U-shaped steel beam, the first support steel plate, the second support steel plate and a tapered column. The above device improves the operation efficiency to a certain extent by hoisting and welding several steel structure shaft units, but the steel structure shaft unit in the above device is an integral structure, which is not convenient for transportation and requires a large operation space, and it is still inconvenient to use.
