In the embodiment, each layer of steel corridor consists of an upper layer of cross beams 1, a lower layer of cross beams 1, a rotating upright 3 for connecting the upper layer of cross beams 1 and the lower layer of cross beams, and a topmost truss layer 2, wherein the cross beams 1 play a role in transverse connection and bearing, personnel pass through the cross beams 1 at the bottom layer of each layer of steel corridor, and the cross beams 1 at the top layer of the layer of steel corridor serve as the bottom layer of the upper layer of steel corridor at the same time; the rotating upright posts 3 are connected with the upper and lower adjacent two layers of cross beams 1, so that the overall stability and the connection strength of the steel corridor are enhanced; in other embodiments, the truss layer 2 may be replaced by the cross beam 1 or other top lifting frame, so long as the truss layer 2 can be connected with the lower structure of the steel gallery and can drive the lower structure to rise under the lifting of the lifting mechanism 100, and the structural form of the truss layer 2 is not limited herein.

Specifically, before the installation of the steel corridor, the constructor places the multi-layer cross beams 1 on the jig frame 200 of the ground in the order of placing from bottom to top, wherein the rotating upright 3 is arranged between two adjacent layers of cross beams 1; at this time, the rotating upright posts 3 are positioned at the stacking positions, the length directions of the rotating upright posts 3 are parallel to the length directions of the cross beams 1, namely, the rotating upright posts 3 are horizontally clamped between the adjacent two layers of cross beams 1, so that the assembly height at the earlier stage is reduced, equipment such as a scaffold or a ladder frame is not required, and the cross beams 1 at each layer can be assembled, thereby reducing the construction cost. Then, a constructor starts the lifting mechanism 100, the lifting mechanism 100 drives the cross beam 1 to ascend through the truss layer 2, and as the first end part of the rotating upright post 3 is rotatably arranged on the cross beam 1, the rotating upright post 3 can rotate to an assembling position under the action of gravity when the upper cross beam 1 ascends, so that the constructor is convenient to assemble, driving equipment is not required to be additionally arranged, and the lifting mechanism has a simple structure and is convenient to operate; when the rotating upright post 3 of the layer rotates to an assembling position, the rotating upright post 3 is in a vertical or inclined state with an included angle with the cross beam 1, so that constructors can fixedly connect the two ends of the rotating upright post 3 with the cross beam 1 on the upper layer and the lower layer respectively, the rotating upright posts 3 do not need to be hung one by one from the ground to the working height, and as the first end of the rotating upright post 3 is rotationally connected with the cross beam 1 on the upper layer, compared with the lifting rotating upright post 3, the connection stability of the rotating upright post 3 and the cross beam 1 is greatly improved, the construction difficulty is reduced, and the safety is improved; in this embodiment, the rotating upright 3 may be vertically connected to the cross beam 1, or may be connected in an inclined manner, so long as the connection stability between the rotating upright 3 and the cross beam 1 can be ensured, which is not limited herein.

In the process that the lifting mechanism 100 drives the cross beam 1 to ascend through the truss layer 2, when the rotating upright post 3 rotates to the assembling position, the constructor stops the lifting mechanism 100 at the moment, and the lifting mechanism 100 is continuously started after the rotating upright post 3 of the layer is fixedly connected with the cross beam 1 of the upper layer and the lower layer, so that the rotating upright post 3 of the lower layer can be lifted to the height where the constructor is located, the constructor can continuously fix the rotating upright post 3, and the operation is repeated, so that the whole assembling of the steel corridor is completed.

Further, the bottom of the cross beam 1 is provided with a hinged support, and the first end is hinged with the hinged support through a pin shaft. Specifically, a through hole is formed in the first end, two lug plates are arranged on the hinged support, a containing channel capable of containing the first end is formed between the two lug plates, and pin holes are formed in the two lug plates; the first end is inserted into the receiving channel between the two ear plates and the through holes are aligned with the pin holes on the two ear plates, and then the pin shaft sequentially passes through the pin holes of one side ear plate, the through holes of the first end and the pin holes of the other side ear plate, so that the rotating upright 3 is rotationally connected to the hinged support.

Specifically, the pin shaft is provided with threads, one end of the pin shaft is provided with a stop plate, and the other end of the pin shaft extending out of the hinged support is in threaded fit with the nut. In this embodiment, after the rotating upright 3 rotates to the assembling position, a constructor needs to fix the first end of the rotating upright 3 with the upper beam 1, and when fixing, a detachable locking device may be used to fixedly connect the first end with the hinge support, or may directly fix the first end with the hinge support by welding; compared with welded connection, the detachable locking device is convenient to adjust the installation angle and the position of the rotating upright post 3, and meanwhile the rotating upright post 3 is convenient to detach and replace in the later period. Specifically, the locking device comprises a pin shaft with a baffle plate and a nut, threads are arranged on the pin shaft, after the rotating upright post 3 rotates to an assembling position, constructors screw the nut on the pin shaft, and through locking of the nut and the baffle plate, the lug plates at two sides of the first end part deform and are abutted against the rotating upright post 3, so that the rotating upright post 3 is fixed and continuous rotation is avoided; the locking device does not need to be provided with a complex fixing device, and can realize the fixation and unlocking of the rotating upright post 3 and the upper cross beam 1 only by screwing nuts, so that the locking device is simple in structure and convenient to operate, the failure rate of the locking device can be reduced, and the manufacturing cost of the steel corridor can be reduced.

Further, in step S4, fixedly connecting the rotating upright 3 with the cross beam 1 includes: fixedly connecting a first end part of the rotating upright post 3 with the cross beam 1 on the upper layer; the second end of the rotating upright 3 is fixedly connected with the lower beam 1. In this embodiment, the constructor connects the two ends of the rotating upright 3 with the upper and lower beams 1, so that the rotating upright 3 and the upper and lower beams 1 are connected into a stable integral structure.

Specifically, the second end of the rotating upright 3 is welded to the lower cross member 1. In the embodiment, the second end is welded with the lower beam 1, so that other structures are not required to be arranged in advance, and the device is convenient to maintain and tight in connection; in other embodiments, a detachable connection manner such as a bolt connection may be used, so long as the connection stability between the rotating upright 3 and the cross beam 1 can be ensured, and the specific connection manner is not limited herein.

In this embodiment, when the lifting mechanism 100 drives the truss layer 2 to lift, the lifting height does not exceed the length of the rotating upright 3, so as to avoid that the second end of the rotating upright 3 cannot be connected with the lower-layer beam 1 due to too large interval between the upper-layer beam 1 and the lower-layer beam 1.

Further, as shown in fig. 1, the step S1 of stacking the multi-layered cross beam 1 in the height direction of the steel gallery includes: placing the bottommost beam 1 on the jig frame 200; the remaining beams 1 are stacked on the beam 1 of the lowermost layer in the height direction of the steel gallery.
