Description

Technical Field

[0001] This application belongs to the field of steel structure building technology, and in particular relates to a lifting operating platform and its construction method. Background Technology

[0002] Steel structure engineering is widely used in various buildings, including industrial buildings, commercial buildings, stadiums, and bridges, due to its advantages such as short fabrication period, fast on-site installation, light weight, good seismic performance, and high degree of industrialization. Among them, space frame structures, with their unique load-bearing performance and spatial advantages, have become one of the main forms of large-span spatial structures. The installation of space frame structures involves numerous high-altitude operations, such as welding the tops of steel columns and connecting bolt balls to space frame members, requiring construction workers to operate at heights for extended periods. Traditional high-altitude work methods often suffer from high safety risks, difficulties in erecting work platforms, and inconvenience in relocation. To ensure construction safety and efficiency, specialized steel platforms are usually required. However, existing steel platforms generally suffer from drawbacks such as heavy weight, complex installation and dismantling, insufficient mobility, and difficulty in adapting to different height requirements. Furthermore, their low material recycling rate increases project costs and time constraints. Summary of the Invention

[0003] This application provides a lifting operating platform and its construction method, aiming to solve the technical problems of existing operating platforms for space frame structure installation being inconvenient to install and dismantle, inflexible to move, difficult to adapt to different heights, and having low material utilization.

[0004] To solve at least one of the above-mentioned technical problems, the technical solution adopted in this application is:

[0005] A lifting operating platform, comprising:

[0006] The platform body includes vertically intersecting horizontal beams and vertical beams, which form a grid-like platform skeleton; several horizontal and vertical bars are also arranged on the horizontal beams and vertical beams to form a mesh support structure.

[0007] The protective assembly includes a plurality of uprights and connecting rods that horizontally connect adjacent uprights. The uprights are located at the outer perimeter of the platform body and at each intersection of the crossbeam and the longitudinal beam.

[0008] The connecting components include lifting rings disposed on the crossbeams and the longitudinal beams, and cantilever beams disposed on the four sides of the steel column;

[0009] The platform body and the protective components are raised to a preset height by hoisting the lifting ring and placed on the cantilever beam pre-welded to the steel column.

[0010] Furthermore, the structure in which the crossbeams and the longitudinal beams intersect is adapted to the cross-sectional dimensions of the steel column, and they are detachably connected at their intersections by bolts.

[0011] Furthermore, the crossbar and the longitudinal bar are detachably connected by a fastener, and the crossbar is welded to the crossbeam and the longitudinal beam.

[0012] Furthermore, the lifting ring is positioned at the center line of the crossbeam and the longitudinal beam, and is vertically upward.

[0013] Furthermore, several panels are laid on the support structure formed by the crossbars and the longitudinal bars, which are fixedly connected to the support structure by steel wire ropes.

[0014] Furthermore, the panel is a wooden template or a wooden board.

[0015] Furthermore, the cantilever beam extends horizontally outward perpendicular to the steel column wall, and the crossbeam and the longitudinal beam are placed on the cantilever beam to fix the platform body to the steel column.

[0019] S1. Based on the cross-sectional dimensions of the steel column, the crossbeams and longitudinal beams are assembled into a platform frame by drilling holes at their intersections using connecting bolts. Vertical lifting rings are welded to the center lines of the crossbeams and longitudinal beams respectively.

[0028] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] This embodiment proposes a lifting operating platform, such as Figure 1 and Figure 2 As shown, the platform mainly consists of three parts: the platform body 10, the protective components 20, and the connecting components 30. The operating platform is fully fitted around the steel column 40 and reliably fixed. It not only has a simple structure, stable stress, and low manufacturing cost, but also allows for rapid assembly and disassembly, significantly improving installation and disassembly efficiency. At the same time, the working height can be flexibly adjusted through hoisting to meet the operational needs of different stages during the installation of the space frame structure.

[0030] Specifically, the platform body 10 includes two horizontal beams 11 and two vertical beams 12 arranged perpendicularly to form a grid-shaped platform skeleton. The grid-shaped skeleton is evenly stressed and can effectively transfer the upper load to the steel column 40. Moreover, the structure of the grid-shaped skeleton is adapted to the cross-sectional dimensions of the steel column and is detachably connected by bolts at the intersection.

[0031] Furthermore, several horizontal bars 13 and vertical bars 14 are arranged on the horizontal beams 11 and 12 to form a mesh support structure. This mesh structure can distribute the construction load and increase the platform's load-bearing area. The horizontal bars 13 and vertical bars 14 are detachably connected by fasteners. Both the horizontal beams 11 and 12 are made of I-beams or channel steel, possessing high load-bearing capacity and strength. The horizontal bars 13, vertical bars 14, uprights 21, and connecting rods 22 are all made of steel pipes, facilitating installation and disassembly. Considering the large cross-sectional dimensions and high load-bearing requirements of the horizontal beams 11 and 12, while the horizontal bars 13 and 14 are relatively slender, welded connections are used between the horizontal bars 13 and 14 and the horizontal beams 11 and 12 to ensure overall structural rigidity and connection strength. The horizontal bars 13 and 14 are detachably connected by fasteners for easy on-site adjustment and disassembly.

[0032] Furthermore, several panels 15 are laid on the support structure formed by the horizontal bars 13 and the vertical bars 14, and are fixedly connected to the support structure by steel wire ropes. The panels 15 provide a flat and non-slip working surface for construction workers, while protecting the underlying structure from direct impact. The panels 15 can be made of wood templates or planks, which are readily available, inexpensive, and easy to replace.

[0033] The protective component 20 is vertically mounted on the mesh platform body 10. It includes several uprights 21 and horizontal connecting rods 22 that link adjacent uprights 21. The uprights 21 are located around the perimeter of the platform body 10, at their ends, and at each intersection of the horizontal beams 11 and the longitudinal beams 12. Because the uprights 21 are made of different materials than the horizontal beams 11 and 12, but the same material as the horizontal and longitudinal beams 13, the bottom of the uprights 21 is welded to the horizontal and longitudinal beams 11 and 12. They are detachably connected to the horizontal and longitudinal beams 13 and 14 via fasteners. The uprights 21 and connecting rods 22 are movably connected via fasteners. Thus, the uprights 21 and connecting rods 22 together form a protective railing, effectively preventing workers and tools from falling and ensuring safety during high-altitude operations. All the uprights 21 are horizontally connected via connecting rods 22, forming multiple interconnected "U"-shaped closed-loop frames, significantly enhancing the overall lateral displacement resistance of the protective component. The specific structure is as follows: Figure 3As shown. Meanwhile, to further enhance the overall stability and safety of the protective component 20, a horizontal connecting rod 22 is added at the midpoint of the inner ring "U"-shaped structure formed by the uprights 21 on the side closest to the steel column 40, connecting all the uprights 21 on that side to each other. Correspondingly, at the midpoint of the largest "U"-shaped structure formed by the uprights 21 at the outermost edge of the platform body 10, another horizontal connecting rod 22 is added, connecting all the outer uprights 21 to each other, forming a stable waist-like reinforcing layer, thereby effectively enhancing the protective component 20's ability to resist lateral impacts.

[0034] The connecting assembly 30 includes lifting rings 31 mounted on the crossbeams 11 and longitudinal beams 12, and cantilever beams 32 mounted on the four sides of the steel column 40. There are four lifting rings 31, positioned at the center lines of the two crossbeams 11 and two longitudinal beams 12, with all rings 31 vertically upwards. This symmetrical arrangement ensures stable platform lifting during hoisting and prevents tilting. The cantilever beams 32 extend horizontally outwards perpendicular to the wall of the steel column 40. The crossbeams 11 and longitudinal beams 12 rest directly on the cantilever beams 32, providing a stable support point for the operating platform, facilitating quick positioning and fixation. The platform body 10 is fixedly connected to the steel column 40 via welding or bolting. The operating platform, consisting of the platform body 10 and the protective assembly 20, is lifted to a preset height by the lifting rings 31 and placed on the cantilever beams 32 pre-welded to the four sides of the steel column 40.

[0035] In this embodiment, the length W2 of the crossbeam 11 and the crossbar 13 is designed to be 6m longer on each side of the width W1 of the steel column 40, i.e., W2 = W1 + 2 × 6m; the length L2 of the longitudinal beam 12 and the longitudinal bar 14 is designed to be 6m longer on each side of the width L1 of the steel column 40, i.e., L2 = L1 + 2 × 6m. This dimensional design ensures sufficient safe operating space around the operating platform, facilitating worker movement and temporary material storage. The crossbeam 11 and the longitudinal beam 12 are made of I-beams or channel steel to ensure load-bearing capacity; the crossbar 13, the longitudinal bar 14, the uprights 21, and the connecting rods 22 are all made of steel pipes for easy on-site handling and disassembly. Preferably, the height of the uprights 21 is greater than 1.2m and not greater than 1.5m, which meets the safety protection standards for construction sites; the horizontal distance between adjacent uprights 21 is not greater than 2m to prevent the risk of personnel falling.

[0036] A construction method for a lifting operating platform as described in any of the preceding claims, comprising the following steps:

[0037] S1. First, assemble the platform frame. Drill holes at the intersection of the horizontal beams 11 and the longitudinal beams 12 according to the cross-sectional dimensions of the steel column 40, and assemble them into a grid-shaped platform frame using connecting bolts. Then, weld four vertical lifting rings 31 at the center line positions of the horizontal beams 11 and the longitudinal beams 12 to ensure balanced force during hoisting. Next, weld several horizontal bars 13 and longitudinal bars 14 onto the platform frame to form a mesh support structure. Finally, lay several panels 15 on the support structure and secure them with steel wire ropes.

[0038] S2. Next, install the protective components, that is, weld the protective uprights 21 around the platform body 10 and at each intersection of the crossbeams 11 and the longitudinal beams 12. The height of the uprights 21 is controlled between 1.2m and 1.5m, and the spacing is no more than 2m. Then, weld or movably connect the horizontal connecting rods 22 between adjacent uprights 21 to form a closed protective fence.

[0039] S3. Platform hoisting and fixing: The assembled operating platform is hoisted to the preset working height by the lifting ring 31, and then the operating platform is placed steadily on the cantilever beams 32 that are pre-welded to the four side walls of the steel column 40, and the crossbeams 11 and longitudinal beams 12 are reliably in contact with the cantilever beams 32, while being secured by welding or bolts.

[0040] S4. Final dismantling and reuse: After the project is completed, disconnect the crossbeam 11, longitudinal beam 12 and cantilever beam 32, then lift the entire operating platform from the cantilever beam 32 to the ground, dismantle all connecting bolts and fasteners, sort and recycle the components, and prepare them for the construction of the next set of steel columns 40, so as to realize the recycling of materials.

[0041] The lifting operating platform designed in this application enables rapid assembly and disassembly, improving installation and dismantling efficiency; it also allows for flexible lifting and lowering of the operating platform at different heights, meeting the varying working height requirements in the installation of space frame structures; the overall structure is stable, safe, reliable, and low-cost. This application also proposes a construction method for the lifting operating platform.

These descriptions are merely preferred embodiments and should not be construed as limiting the scope of this application. All equivalent variations and modifications made within the scope of this application should still fall within the patent coverage of this application.
