Most bridge support frames use cup-hook scaffolding, and some use portal scaffolding. Most ground-mounted scaffolding for main structure construction uses coupler scaffolding. When constructing cup-hook scaffolding, portal scaffolding and coupler scaffolding, especially high-rise scaffolding, all materials used must meet quality requirements. At the same time, the foundation of high-rise scaffolding must be firm. It must be calculated before erection to meet the load requirements. The technical requirements for erection must comply with relevant specifications.

[0022] A mobile scaffold for building construction, as shown in the attached Figure 1 As shown, it includes multiple layers of rectangular horizontal support frames distributed up and down, and two adjacent layers of horizontal support frames are connected by four main vertical poles 1. A working platform 2 is arranged at the upper end of the horizontal support frame located on the top layer, and a protective fence 3 is fixed around the upper surface of the working platform 2. A stabilizing mechanism is arranged on the lower surface of the horizontal support frame located on the bottom layer, and a universal wheel 4 is fixedly connected to each of the four corners of the lower end of the horizontal support frame located on the bottom layer.

[0023] The structural design of the horizontal support frame and the main upright 1 in the utility model constitutes the basic frame structure of the scaffolding. The multi-layer design provides a sufficient working height. The upper and lower layers are connected by the main upright 1 to ensure the vertical stability of the entire scaffolding structure, solving the problem that the traditional scaffolding is complicated and time-consuming to build. The structural design of the working platform 2 and the protective fence 3 provides a safe operating space for construction personnel, which can prevent construction personnel from accidentally falling and ensure the efficiency and safety of the operation. The structural design of the universal wheel 4 allows the scaffolding to be flexibly moved in the construction area, adapting to the needs of different work points and improving work efficiency.

[0024] As attached Figure 1 ~Attached Figure 2As shown, the stabilizing mechanism includes a positive and negative longitudinal screw rod 5, the front and rear parts of which are each threadedly connected with a screw block 6, and the front end of the positive and negative longitudinal screw rod 5 is fixed with a manual disk 7, the lower surface of each screw block 6 is connected with a transmission cross bar 8, and the two ends of each transmission cross bar 8 are respectively connected with a stabilizing block 9, the upper surfaces of the two stabilizing blocks 9 located at the front part of the positive and negative longitudinal screw rod 5 are fixed to the lower surface of the front cross bar of the horizontal support frame, and the upper surfaces of the two stabilizing blocks 9 located at the rear part of the positive and negative longitudinal screw rod 5 are fixed to the lower surface of the rear cross bar of the horizontal support frame.

[0025] As attached Figure 3 ~Attached Figure 5 As shown, the stabilizing block 9 includes a shell-shaped stabilizing block body 10, the inner cavity of the stabilizing block body 10 is slidably connected with a first pressure block 11 and a second pressure block 12, the lower surface of the first pressure block 11 is in contact with the upper surface of the second pressure block 12 at an inclined surface and is slidably connected, a sliding groove is provided on the side of the stabilizing block body 10 close to the transmission cross bar 8, and the end of the transmission cross bar 8 is fixedly connected to the corresponding first pressure block 11 through the sliding groove, and a support plate 13 is arranged below the stabilizing block body 10, and the second pressure block 12 is connected to the support plate 13 through a spring 14.

[0026] The inclined plane directions between the first pressing block 11 and the second pressing block 12 of two stabilizing blocks 9 connected by the same transmission cross bar 8 are the same; the inclined plane directions between the first pressing block 11 and the second pressing block 12 of two stabilizing blocks 9 connected by different transmission cross bars 8 are opposite.

[0027] The structural design of the stabilizing mechanism realizes the stable fixation of the scaffold. The lifting and lowering of the support plate 13 can be controlled by adjusting the forward and reverse longitudinal screw rods 5. When the scaffold needs to be fixed, only the two screw blocks 6 of the forward and reverse longitudinal screw rods 5 will move toward each other at the same speed by operating the manual disk 7, that is, the two screw blocks 6 drive the corresponding transmission cross bars 8 to approach each other, so that each first pressing block 11 slides relative to the corresponding second pressing block 12 while pressing the corresponding second pressing block 12 downward, so that the second pressing block 12 drives the support plate 13 to descend through the spring 14 and presses the support plate 13 to make it contact with the ground, so that each universal wheel 4 is in a braking state, ensuring that the scaffold The scaffolding stops stably and can disperse the weight at the same time, reduce the pressure on the universal wheel 4 and extend its service life. When the scaffolding needs to be moved, the manual disk 7 only needs to be operated in the reverse direction, and the two screw blocks 6 of the forward and reverse longitudinal screw rods 5 will move in opposite directions at the same speed, that is, the two screw blocks 6 drive the corresponding transmission cross bars 8 to move away from each other, so that each first pressing block 11 slides in the opposite direction relative to the corresponding second pressing block 12, and the restoring force of the spring 14 presses the corresponding second pressing block 12 upward until the spring 14 gradually returns to its original state, so that the support plate 13 and the ground are loosened, so that each universal wheel 4 is released from the braking state, so that the scaffolding can be moved.

[0028] As attached Figure 1 As shown, a footboard 15 is fixedly connected to the lower portion of the protective fence 3, and the footboard 15 is made of wood.

[0029] The structural design of the footboard 15 can prevent small tools or materials placed on the working platform 2 from sliding down, thereby improving the safety level of the operation, especially for high-altitude working environments.

[0030] As attached Figure 1 As shown, a plurality of reinforcing uprights 16 are arranged between two adjacent layers of horizontal support frames, and a reinforcing diagonal rod 17 is fixed between each reinforcing upright 16 and the adjacent main upright 1 .

[0031] The structural design of the reinforced vertical rods 16 and the reinforced diagonal rods 17 enhances the overall rigidity and stability of the scaffold, especially when carrying heavy objects or in complex working conditions, thereby ensuring the stability of the structure.

[0032] As attached Figure 1 As shown, a ladder 18 is provided between the horizontal support frame at the bottom layer and the working platform 2 , and the protective fence 3 is provided with an entrance and exit at the upper end of the ladder 18 .

[0033] The design of the ladder 18 provides a convenient up and down passage for construction workers, and the design of the entrance and exit makes it safer and more convenient to enter and exit the working platform 2.

[0037] When the utility model is used, the scaffold is directly pushed to the working point, and then the scaffold is fixed. By operating the manual disk 7, the two screw blocks 6 of the positive and negative longitudinal screw rods 5 move toward each other at the same speed, that is, the two screw blocks 6 drive the corresponding transmission cross bars 8 to approach each other, so that each first pressing block 11 slides relative to the corresponding second pressing block 12 and presses the corresponding second pressing block 12 downward, so that the second pressing block 12 drives the support plate 13 to descend through the spring 14 and presses the support plate 13 to make it contact with the ground, so that each universal wheel 4 is in a braking state, ensuring that the scaffold stops stably, and then the construction personnel can reach the working platform 2 through the ladder 18 and the entrance and exit to carry out construction work; when it is necessary to move the scaffold, the construction personnel can reach the working platform 2 through the ladder 18 and the entrance and exit to carry out construction work; when it is necessary to move the scaffold, the construction personnel can reach the working platform 2 through the ladder 18 Down to the ground, and then operate the manual disk 7 in reverse, the two screw blocks 6 of the forward and reverse longitudinal screw rods 5 will move in opposite directions at the same speed, that is, the two screw blocks 6 drive the corresponding transmission cross bars 8 to move away from each other, so that each first pressure block 11 slides in the opposite direction relative to the corresponding second pressure block 12, and the restoring force of the spring 14 presses the corresponding second pressure block 12 upward until the spring 14 gradually returns to its original state, so that the support plate 13 and the ground are loosened, so that all universal wheels 4 are released from the braking state, so that the scaffolding can be moved to the next work point to continue working, thereby completing the use of the scaffolding; overcoming the problems of the existing scaffolding in the construction process, such as complicated on-site erection steps, time-consuming and labor-intensive, long construction period and inability to move.
