The forklift transports the corbel 3 to the reserved corbel 3 and lower chord beam of the corridor body 1, and then the corbel 3 and the lower end of the corridor body 1 are lifted by the lifting unit 2, and then the corridor body 1 is driven by the hydraulic lifter. When the body 1 moves up, the corbel 3 is lifted synchronously with the corridor main body 1 under the drive of the lifting unit 2, and is lifted and hovered at the reserved corbel 3 elevation position, and the hovering position is no more than 50mm lower than the reserved corbel 3, and then the position of the corbel 3 is fine-tuned by the adjustment unit 4, so that the splicing plate on the corbel 3 is butted with the bolt holes on the splicing plate on the wall, and the splicing plate is fixed by bolts, and then the corbel 3 is poured with concrete to complete the installation pre-fixation of the corbel 3, and then the corridor main body 1 is fixed on the corbel 3, and the installation and fixation of the corridor main body 1 is completed.

[0034] In one embodiment, the hoisting unit 2 includes a fixing ring 21 symmetrically arranged at the lower end of the corridor body 1, a steel wire rope 22 arranged on the fixing ring 21, and a support rod 23 passed through the corbel 3, the steel wire rope 22 is sleeved on the support rod 23, and the support rod 23 is threadedly connected with a first nut 24 for fixing the steel wire rope 22.

[0035] In this design, four fixing rings 21 are fixed to the lower end of the corridor body 1, and then the wire rope 22 is fixed to the fixing ring 21, and then four lifting rings are installed on the corbel 3, the support rod 23 is inserted between the two lifting rings, the bottom of the wire rope 22 is sleeved on the support rod 23, and then the wire rope 22 is fixed between the first nut 24 and the lifting ring through the first nut 24, so that the corbel 3 is connected to the corridor body 1, and an electric hoist is installed on the corridor body 1, and after the corbel 3 is hoisted to the reserved corbel 3 elevation position, the electric hoist is connected to the corbel 3, and then the lateral position of the corbel 3 is adjusted by the electric hoist, so that the corbel 3 moves to the side close to the reserved splicing plate, and then the splicing plate on the corbel 3 is connected and fixed to the splicing plate at the elevation position on the high-rise building.

[0038] In this design, a fixed frame 48 is installed at the lower end of the corridor body 1, and then an adjusting device is installed on the fixed frame 48. After the corbel 3 is hoisted to the reserved corbel 3 elevation position, the adjusting device adjusts the installation position of the hoisting plate 46, and the hoisting plate 46 drives the corbel 3 at the lower end of the wire rope 22 to move horizontally.

[0039] In one embodiment, the adjusting device includes a motor 41 fixed on a fixed frame 48, a screw 42 arranged at the power output end of the motor 41 and rotatably connected to the fixed frame 48, and a screw sleeve 43 threadedly connected to the screw 42.

A mounting groove 4611 for placing the screw sleeve 43 and the slider 44 is opened at the position of the fixed frame 461 corresponding to the screw sleeve 43 and the slider 44, and a through groove 441 is opened at the position of the slider 44 corresponding to the fixed rod 471.

[0044] In this design, the slider 44 is slidably sleeved on the guide rod 45, and then the slider 44 is fixed to the fixing frame 461 through the fixing rod 471. Then, when the screw 42 drives the screw sleeve 43 to move, the slider 44 slides on the guide rod 45 with the screw sleeve 43, which can improve the stability of the movement of the fixing frame 461.

[0045] In one embodiment, hanging ears 31 are fixed on both sides of the corbel 3 for facilitating installation of the support rod 23 .

The four steel wire ropes 22 have the same length, so that the corbel 3 can be more stable when it is lifted.

[0047] In one embodiment, a support frame 11 is fixed to the lower end of the corridor body 1 , and a placement groove 111 for placing the fixing frame 48 is opened at the position of the support frame 11 corresponding to the fixing frame 48 .

[0048] With such a design, the placement groove 111 can store the fixing frame 48 , and when the extended length of the motor 41 affects the upward movement of the corridor body 1 , the motor 41 can be fixed inside the placement groove 111 .

[0049] In one embodiment, a fixing plate 12 is fixed to the side of the support frame 11 near the placement groove 111 , and a rubber support 5 for buffering the corridor body 1 is fixed to the lower end of the fixing plate 12 .
