Description

Technical Field

[0001] This invention belongs to the field of steel structure installation application technology, and specifically relates to a modular mobile work platform for steel structure installation. Background Technology

[0002] During steel structure installation, a significant amount of work needs to be performed at heights, such as welding, bolting, and hoisting. Therefore, it is essential to provide stable working platforms for construction workers to ensure they have a stable foothold and effectively prevent accidents caused by uneven or unstable ground. Currently, installing scaffolding on the outside of the steel structure can provide a stable working platform. However, for steel structures of uniform height, if scaffolding is required at every point, its disadvantages become fully apparent: time-consuming and labor-intensive erection and dismantling, significant safety risks, damage to the ground, susceptibility to weather conditions, and space occupation. Furthermore, in recent years, scaffolding costs in installation projects have been continuously rising, becoming a major challenge for project cost control. Therefore, there is a need to develop a new working platform that can more safely, economically, and efficiently complete steel structure installation work. Summary of the Invention

[0003] To address the aforementioned issues, this invention discloses a modular mobile work platform for steel structure installation, which is scalable and quick-assembly compliant, achieving an optimal balance between quality, safety, schedule, and cost while ensuring safety, economy, efficiency, and applicability.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A modular mobile work platform for steel structure installation includes a work unit, a bracket, a road surface mat, and a fixing device. The working unit includes a square base with guardrails on all four sides. A ladder opening is located at the center of the front end of the base, and the ladder opening has a cover plate. The height of the highest guardrail of the working unit is 4-10cm higher than the upper plane of the high-altitude horizontal steel structure. Two L-shaped hooks are bolted to the guardrail at the front end of the working unit. The hanging frame includes a hollow square column structure formed by a ladder and railings. The ladder is set on the front face, the railings surround the other three faces, and the top of the ladder is connected to the ladder opening. The road surface mat is placed on the ground below the bracket, and a pad or adjustable bolt is provided between the road surface mat and the bracket; The fixing device includes two long channel steels and two short channel steels. The two long channel steels are placed longitudinally above the high-altitude horizontal steel structure, and their rear ends are connected to the guardrail. The two short channel steels are placed longitudinally below the high-altitude horizontal steel structure. The front ends of the two long channel steels and the two short channel steels are clamped to the high-altitude horizontal steel structure by long screws. The front end of the working unit is attached to one side of the high-altitude horizontal steel structure. The L-shaped hook has its horizontal surface positioned above the high-altitude horizontal steel structure, and its vertical surface is perpendicularly downward along the other side of the high-altitude horizontal steel structure.

[0005] As an improvement of the present invention, the guardrail, ladder and railing are all made of square tubing.

[0010] As an improvement of the present invention, a long rope is provided on one side of the working unit, and a pulley is provided on the railing at the rear end of the working unit.

[0011] As an improvement of the present invention, an anti-slip block is fixedly connected to the back of the road surface pad, and the anti-slip block is a rubber block.

[0022] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0023] As shown in the figure, the modular mobile work platform for steel structure installation described in this invention is designed for horizontal steel structures of approximately the same height, with a minimum height of 10m, requiring construction at different points (meaning the work platform needs to be constantly erected). In this case, scaffolding is not cost-effective, so a new work platform has been designed, the specific structure of which is as follows: It includes working unit 1, hanging bracket 2, road surface mat 3, and fixing device. The working unit 1 includes a square base 4, with guardrails 5 on all four sides of the base 4. A ladder opening is located at the center of the front end of the base 4, and a cover plate 6 is on the ladder opening. The height of the highest guardrail 5 of the working unit is 4-10cm higher than the upper plane of the high-altitude horizontal steel structure 15. Two L-shaped hooks 7 are connected to the guardrail 5 at the front end of the working unit 1 by bolts. The hanging frame 2 includes a hollow square column structure formed by a ladder 8 and a railing 9. The ladder 8 is set on the front end, and the railing 9 surrounds the other three sides. The ladder 8 is connected to the ladder opening at the top. The road surface mat 3 is placed on the ground below the bracket 2, and a pad 10 or an adjustable bolt 11 is provided between the road surface mat 3 and the bracket 4. The fixing device includes two long channel steels 12 and two short channel steels 13. The two long channel steels 12 are placed longitudinally above the high-altitude horizontal steel structure 15, and their longitudinal rear ends are connected to the guardrail 5. The two short channel steels 13 are arranged longitudinally below the high-altitude horizontal steel structure 15. The front ends of the two long channel steels 12 and the two short channel steels 13 are clamped to the high-altitude horizontal steel structure 15 by long screws 14. The front end of the working unit 1 is attached to one side of the high-altitude horizontal steel structure 15. The L-shaped hook 7 is positioned horizontally above the high-altitude horizontal steel structure, and its vertical surface is perpendicularly downward along the other side of the high-altitude horizontal steel structure.

[0024] In operation, the crane is first used to hook the working unit 1, making the entire working platform stand upright. Two L-shaped hooks 7 are used to hook the high-altitude horizontal steel structure 15 for temporary positioning. The gap between the hanging frame 2 and the road surface mat 3 below is filled with shims 10 or adjustable bolts 11 to ensure that the road surface mat 3 is pressed stably on the road surface. Then, the operator crawls into the hanging frame 2 and enters the working unit along the ladder 8. After the cover plate 8 is closed, the fixing device is installed. The front ends of the two long channel steels 12 and the two short channel steels 13 are clamped to the high-altitude horizontal steel structure 15 by long screws 14. The longitudinal rear ends of the two long channel steels 12 are connected to the guardrail 5. Finally, the crane is released, and the operator can carry out the next operation on the high-altitude horizontal steel structure inside the working unit 1.

[0025] This invention is actually a hanging frame, suspended on a high-altitude horizontal steel structure 15. The upper working unit 1 facilitates worker operation inside, and the outer perimeter is protected by guardrails. The guardrails of this invention also serve several functions: 1. The front end (the surface where the guardrail is in close contact with the high-altitude horizontal steel structure 15 is called the front end) has two L-shaped hooks 7 on top of the guardrail 5, such as... Figure 2 and 3 As shown, this facilitates initial positioning; 2. The guardrails on the left and right sides are connected to two long channel steels 12 to fix the working unit on one side of the high-altitude horizontal steel structure 15. 3. The guardrail 5 at the front end of the working unit can also be made into part of the ladder 8 to facilitate the operator's climbing.

[0026] A ladder opening is provided at the front center of the base 4. The ladder opening has a cover plate 6. The cover plate seals the ladder opening during normal operation. The cover plate 6 has a movable handle. The handle is normally folded down and can be lifted up when in use to make it easy to lift the cover plate. In addition, the size of the cover plate is also controlled. The shortest side of the cover plate 6 is longer than the diagonal length of the cross section of the bracket 2 to ensure that the cover plate will not fall from the ladder opening and injure people.

[0027] The height of the highest guardrail 5 of the working unit described in this invention is slightly higher than the upper plane of the high-altitude horizontal steel structure 15. When the two long channel steels 12 are placed longitudinally above the high-altitude horizontal steel structure 15, they are about the same height as the highest guardrail 5. The highest guardrail 5 and the channel steel are connected and fixed together by multiple bolts.

[0028] The guardrail 5, ladder 8 and railing 9 described in this invention are all made of square tubing, with the surfaces tightly fitted together, making it easy to fix with bolts.

[0029] The L-shaped hook 7 described in this invention can be designed to be telescopic, adjusting its length according to the cross-sectional size of the steel beam, thereby expanding its applicability.

[0030] The bracket 2 described in this invention can be made by assembling standard sections, and the number of standard sections is determined according to the height.

[0031] like Figure 5 As shown, due to the different elevations of the pipe gallery, in addition to using standard sections to adjust the overall height, if the distance between the bottom of the bracket 2 and the ground pad is less than 100mm, flat shims (pads 10) are used for adjustment. After fixing, they are spot welded with electric welding to prevent the shims from slipping.

[0032] like Figure 6 As shown, when the distance between the bottom of the bracket 2 and the ground pad is greater than 100mm (less than the height of a standard section), the adjustable bolt 11 is used for adjustment. The adjustable bolt 11 is connected to the bottom of the bracket by bolts. By adjusting the length of the adjustable bolt 11, all the legs of the bracket are in full contact with the ground pad 3. The upper hook, clamp and bottom legs are fully stressed, ensuring the overall stability.

[0033] The road surface mat 3 of the present invention has an anti-slip block 20 fixedly connected to its back. The anti-slip block 20 is a rubber block that increases friction with the ground and will not easily slide or tip over.

[0034] Because the bracket 2 is very tall, to prevent lateral slippage or tipping, the side of the bracket 2 described in this invention is fixedly connected to the steel structure column 16 by angle iron 17. Figure 1 As shown.

[0035] like Figure 3 As shown, the present invention has a long rope 18 on one side of the working unit 1 and a pulley 19 on the rear railing of the working unit 1, which facilitates manual hoisting of items or tools.

[0036] The construction platform described in this invention adopts a mobile hanging frame. Under the premise of considering safety, rationality, and economy, it forms a complete and scientifically reasonable installation method for mobile hanging frame construction platform, reducing the amount of scaffolding erected, lowering costs, and increasing installation speed. The platform has good stability after installation, improving the installation speed and labor productivity of mobile hanging frame construction platform. The platform does not deform during hoisting, giving it a strong market competitiveness.

[0037] It should be noted that the above content merely illustrates the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, various improvements and modifications can be made without departing from the principle of the present invention, and all such improvements and modifications fall within the scope of protection of the claims of the present invention.
