[0013] Example

[0014] See attached document Figures 1 to 3This embodiment improves the operating platform by proposing a movable high-rise scaffold, including a main frame 1, scaffold boards 2, and a frame support platform 3. The main frame 1 includes four uprights 11 arranged in a square at the four corners. The upper, middle, and lower parts of the four uprights 11 are connected and fixed by crossbeams 12. Cross supports 13 are also fixed between the uprights 11. Scaffold boards 2 are erected between the upper crossbeams 12 to form the operating platform. The height of the main frame 1 is 1.6-4.8 meters. The width and length of the frame support platform 3 are at least 1.5 times the width and length of the main frame 1. The height of the frame support platform 3 does not exceed 30cm. The height of the frame support platform 3 shown in the figure is 25cm. The long side of the frame support platform 3... A frame slot 31 is provided for engaging the main frame 1. The width of the frame slot 31 is greater than the length of the main frame 1, and the depth of the frame slot 31 is greater than half the width of the main frame 1. At least three diagonal braces 32 are provided on the frame support platform 3. The at least three diagonal braces 32 are inclined from at least three directions. The upper end of the diagonal brace 32 is detachably fixed to the upright 11 of the main frame 1 by scaffold fastener 4. The lower end of the diagonal brace 32 is welded and fixed to the frame support platform 3. After use, the scaffold fastener 4 is removed, and the lower end of the diagonal brace 32 is separated from the frame support platform 3. The separation method can be achieved by cutting. Universal wheels 5 are installed at the four corners of the bottom of the main frame 1 and the frame support platform 3, and each universal wheel 5 is equipped with a locking wheel device.

[0015] The specific usage method is as follows:

[0016] (1) Basic processing:

[0017] Before erecting the working platform, the foundation needs to be treated to ensure it is flat and firm, preventing the scaffolding from tilting or collapsing due to instability. The foundation for the working platform typically uses a hardened concrete surface for the main structure. In outdoor work areas, the soil foundation needs to be compacted, and wooden blocks should be laid at the bottom for leveling. At the same time, ensure that there are no other debris piled up in the work area, especially items that could easily collapse and impact the platform.

[0018] (2) Main frame installation:

[0019] The uprights 11 and crossbeams 12 of the main frame 1 are made of 48mm×3.5mm aluminum alloy steel pipes, which are connected in one piece. The overall height is 2m, ensuring the firmness and stability of the overall frame.

[0020] The longitudinal connection uses 30mm×3.5mm aluminum alloy steel pipes, which are arranged in a scissor-fork pattern at the connection holes of the two side columns to form cross supports 13, thereby enhancing the overall structural stability of the platform.

[0021] (3) Scaffolding board laying:

[0022] Scaffold boards 2 are laid on each working level of the operating platform. Scaffold boards 2 are perforated steel boards, with dimensions of 300mm wide * 1800mm long * 50mm thick. They feature internal stiffening plates and inverted snap-fit ​​grooves at each end, forming a single, integrated steel scaffold board. The module of scaffold board 2 is a multiple of the internal dimensions of the platform columns to ensure standardized installation and use. U-shaped snap-fit ​​grooves are provided at the ends of scaffold boards 2. During installation, the grooves are inverted and snapped onto the crossbeams 12, ensuring a secure fixation without looseness or gaps to guarantee the safety of construction workers. Common scaffold board materials include steel plates and wooden boards.

[0023] (4) Install casters:

[0024] According to the dimensions required in the design drawings, a suitable open location was selected for welding the main frame 1. During welding, the anchorage length between the caster wheel 5 and the bottom of the main frame 1 was determined through stress analysis and calculation of the bottom members. Based on the above operations, the position of the caster wheel 5 was determined by marking the corresponding rectangular steel positioning lines at the bottom of the frame. After the positioning lines were completed, the wheel axle was welded to the bottom member. During the welding process, it was ensured that the weld between the wheel axle and the bottom member was full and free of weld bubbles or other defects. After the welding of the caster wheel 5 to the bottom member was completed, the welding position was checked for any deviations. If no deviations were found, an external load was added above the bottom frame to test whether the caster wheel 5 could operate normally under the load. The caster wheel 14 has a diameter of 150mm and uses wear-resistant rubber pulleys. The pulleys should be easily fixed to the bottom of the scaffolding and have a locking device. Common caster wheel locking devices can be used to ensure safety during use.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
