Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a modular operating platform for constructing three-dimensional characters on steel roof trusses of high-rise buildings and its construction method. Background Technology

[0002] When installing large three-dimensional lettering on the steel roof truss of high-rise buildings, construction work typically needs to be carried out at the height of the roof frame floor. Traditional construction methods often use full-span scaffolding or suspended platforms as working platforms. However, due to the complexity of the roof steel frame structure and limited space, full-span scaffolding has a long erection period, consumes a large amount of materials, and is difficult to erect mechanical equipment due to the already completed paving and curtain wall around the building; while suspended platform operations are constrained by the difficulty in setting up suspension points on the steel roof truss and the inconvenience of simultaneous operation at multiple points. In addition, when using traditional methods for high-altitude edge work, safety protection measures are often insufficient to provide comprehensive coverage, posing safety hazards such as personnel falls and falling objects.

[0003] On the other hand, while some existing technologies offer detachable working platforms for steel structure construction, most are monolithic structures, making transportation and installation inconvenient and difficult to adjust flexibly to meet the varying heights of the steel frame. Especially when existing curtain walls are already installed, the protection of finished decorative surfaces such as anodized aluminum panels must be considered during construction. Existing working platforms generally lack integrated designs with fire prevention, fall protection, and welding protection functions, resulting in low construction efficiency, high safety risks, and significant challenges in protecting finished products. Therefore, there is an urgent need for a high-altitude work platform that is simple in structure, easy to assemble and disassemble, safe and reliable, and possesses integrated protective functions. Summary of the Invention

[0011] Preferably, in step S1, the uprights of the fixing frame are made of 80×80×4.75mm galvanized square steel, and are constructed by welding the uprights in one go and welding the crossbars and diagonal bars in sections.

Platform plate 8 is fixed to the long side guardrail 5 and the short side guardrail 6 by end slots; The cantilever length of the long side guardrail 5 is 300-500mm; A storage mechanism 9 is provided on the outer side of the short crossbar 2; The storage mechanism 9 includes a frame 91, which is movably connected to the outside of the short side crossbar 2. A connecting plate 901 is fixedly connected to the bottom of the frame 91. A threaded rod 94 is provided inside the connecting plate 901. A rectangular plate 97 is threadedly connected to the outer wall of the threaded rod 94. A support arm 98 is fixedly connected to the top of the rectangular plate 97. An insert block 99 is fixedly connected inside the support arm 98. A worm gear 95 is fixedly connected to the outer wall of the threaded rod 94. A worm 96 is meshed on the outer ring of the worm gear 95. A right-angle plate 92 is fixedly connected to the top of the frame 91.

[0024] Furthermore, both the threaded rod 94 and the worm gear 96 are rotatably connected to the inner wall of the support box 93, and a handwheel is fixedly connected to one end of the worm gear 96.

[0025] Furthermore, a rotating hole is provided inside the connecting plate 901, and the threaded rod 94 is rotatably connected to the inner wall of the rotating hole.

[0026] Furthermore, a second rotating hole is provided at the bottom of the support box 93, through which the threaded rod 94 passes and rotates. A method for constructing three-dimensional characters on a high-rise building steel roof truss, employing a modular operating platform, includes the following steps: S1. Weld the uprights of the fixed frame onto the steel roof truss; S2. Connect the long side guardrail 5 to the longitudinal bar of the fixing frame using bolts; S3. Connect the short side guardrail 6 to the long side guardrail 5 using a pin; S4. Connect the platform plate 8 to the short side guardrail 6 via the end slot; S5. Connect the platform plate 8 to the long side guardrail 5 through the end slot to form a complete operating platform; S6. Perform the welding of the fixing frame and the installation of the three-dimensional lettering on the operating platform. Further, in step S1, the uprights of the fixing frame are made of 80×80×4.75mm galvanized square steel, and the construction is carried out by welding the uprights in one go and welding the horizontal and diagonal bars in sections.

[0027] Furthermore, after step S5 and before step S6, a fireproof cloth and a horizontal safety net are erected below the operating platform. The fireproof cloth is located above the horizontal safety net, and the distance between the fireproof cloth and the steel pipe system of the operating platform is ≤50cm.

[0028] Furthermore, in step S6, a fire-collecting bucket is used to collect sparks during the welding of the fixed frame. The fire-collecting bucket is suspended on the outside of the operating platform by a telescopic bracket and its position can be adjusted by sliding along the guardrail.

[0029] The specific working principle is as follows: the long side guardrail 5 is connected to the longitudinal rod of the fixing frame by bolts, the short side guardrail 6 is quickly fixed to the long side guardrail 5 by a pin-type self-locking mechanism, and 8 is engaged with the guardrail by an end slot, forming a stable and detachable operating platform. During construction, the principle of welding the columns in one go and welding the horizontal and diagonal bars in sections is followed. The operating platform is erected in layers according to the height of the steel frame, and the welding work of each layer of fixing frame is completed in sequence. Fireproof cloth and horizontal safety nets are laid under the operating platform. During welding operations, a fire-catching bucket is used to collect sparks to protect the finished curtain wall below; at the same time, the uprights are fixed on the steel beams by bottom clamps and steel wire ropes are strung to form a horizontal lifeline. Through the above structure and method, the rapid and safe construction of high-altitude three-dimensional lettering installation is achieved.

[0030] The clip frame 91 is inserted into the outside of the short side crossbar 2 to provide initial support. Then, the handwheel is turned to rotate the worm gear 96. The worm gear 96 can drive the worm wheel 95 to rotate through meshing. The worm wheel 95 can drive the threaded rod 94 to rotate. The threaded rod 94 and the rectangular plate 97 are threadedly connected, and the support arm 98 can slide and limit the movement on the outside of the clip frame 91. This allows the rectangular plate 97 to drive the insert block 99 to be inserted into the limiting port, thus limiting the clip frame 91. This allows the toolbox 902 to be connected and installed, facilitating the storage of tool parts, reducing the loss of tool parts, and facilitating further construction work.
