The following is a detailed description of a specific structure of the mobile cantilever scaffold.

The bearing support 1 is used for matching with a structure of a building to carry the overhanging scaffold. As shown in fig. 3, each force bearing support 1 is composed of a barb part and a horizontal bearing part which are connected with each other. The bearing support 1 is formed by welding profile steel (square steel pipes can be adopted in other methods), the hook body span of the barb part in the bearing support 1 is slightly larger than the section width of the upturned beam 2 in a building to be constructed, so that the barb part can be clamped into the upturned beam 2 from the upper part, and one side of the barb part, which is connected with the horizontal bearing part, is attached to the side surface of the upturned beam 2.

As shown in fig. 4, the steel frame 3 is formed by welding square steel pipes, and includes a vertical frame and two horizontal frames. In the embodiment, the steel tube frame is formed by welding three vertical square steel tubes and two horizontal square steel tubes, and each layer of horizontal frame is provided with three square steel tubes. The bottom of the steel frame 3 is fixed at the tail end of the horizontal bearing part of the 3 bearing supports 1. Two ends of the lower horizontal frame in the steel frame 3 are respectively fixed on the vertical frame and the barb part of the bearing support 1. In addition, the tail ends of 3 square steel pipes of the upper horizontal frame in the steel frame 3 are respectively provided with 1 first U-shaped hook 5, and the first U-shaped hooks 5 are formed by welding the square steel pipes. Of course, the specific steel pipe usage and arrangement position in the steel frame 3 can be adjusted as required, the steel frame 3 forms for different construction environments can be different, and the facade frame can be composed of one side or a plurality of sides.

Referring to fig. 1 and 2, after the whole steel frame 3 is welded, the height difference between the bearing support 1 and the first U-shaped hook 5 is consistent with the floor height of the building to be constructed, so that the barb part of the bearing support 1 and the first U-shaped hook 5 can be respectively hooked with the barb of the upturned beam 2 of the upper floor and the lower floor adjacent to each other in the building. Therefore, the whole movable cantilever scaffold can be reversely buckled on the two-layer upturning beam through the bearing support and the U-shaped hook, and the load of the scaffold is transferred to a building, so that movable mounting is realized. It should be noted that the barb part of the force bearing support 1 and the first U-shaped hook 5 can be mounted on one or more side surfaces of the upturned beam 2 (two different side surfaces are mounted in fig. 1), and the requirements are determined according to the actual construction environment, and are not particularly limited.

In addition, in order to maintain the stability of the entire mounting, a plurality of diagonal wires 7 need to be provided on the upper portion of the steel frame 3, and the diagonal wires 7 are used to apply a lateral pulling force to the upper portion of the mobile cantilever scaffold. The tail end of each diagonal steel wire rope 7 is connected with a second U-shaped hook 9, the form of the second U-shaped hook 9 is the same as that of the first U-shaped hook 5, and the second U-shaped hook 9 is also used for being hung on the inverted hook of the floor slab upturning beam 2 above the steel frame 3 to form a diagonal form shown in fig. 2.

In order to facilitate the connection and detachment of the diagonal steel wire rope 7, in this embodiment, a first connecting piece 8 is fixed at a position above the upper horizontal frame in the steel frame 3, a second connecting piece 10 is fixed on the second U-shaped hook 9, and two ends of the diagonal steel wire rope 7 are respectively fixed with the first connecting piece 8 and the second connecting piece 10. And the first connecting member 8 and the second connecting member 10 may be round steel tabs. The inclined pull steel wire rope 7 adopts a phi 16 steel wire rope.

In addition, the periphery of the steel frame 3 needs to be provided with a building envelope. In this embodiment, an enclosure structure is required to be arranged above the two layers of horizontal frames. The enclosure structure is composed of an enclosure steel pipe 4 and a color steel plate 11, as shown in fig. 5, the enclosure steel pipe 4 is fixed on the steel frame 3 as a framework, and the color steel plate 11 surrounds the enclosure steel pipe 4 and the steel frame 3. Besides one side attached to the building, the rest three sides are required to be provided with an enclosure, so that the final enclosure structure adopts a construction enclosure with three enclosed sides.

As shown in fig. 6, in order to facilitate the construction operation, the upper surfaces of the two layers of horizontal frames are required to be paved with the formworks 6, wherein the lower layer of formworks 6 are used as the construction surface, and the upper layer of formworks 6 are used for protection, so that the sundries falling from the upper side are prevented from causing harm to constructors. The bottom of the template 6 can be further paved with steel pipes as keels.
