Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a high-altitude operation platform for the protective construction of multi-story pipe corridors. Background Technology

[0002] In existing technologies, the high-altitude construction of multi-story pipe gallery scaffolding for secondary lifting typically employs a full-span support system. Uprights, horizontal bars, and diagonal braces work together to bear the load, with wooden planks or steel scaffolding laid on top. However, full-span scaffolding requires a large number of components, resulting in high material rental or procurement costs, especially with low turnover rates during large-scale operations. Manual assembly layer by layer is inefficient, and the subsequent dismantling process is equally complex, potentially damaging existing pipelines. Furthermore, the full-span scaffolding obstructs passage in the lower space and can interfere with other work processes. Therefore, the use of full-span scaffolding for high-altitude pipe gallery work platforms presents several technical challenges, including the need for numerous components, complex installation and dismantling procedures, reduced construction efficiency, occupation of lower construction space, and potential disruption to other work processes.

In the description of the present invention, it should be understood that terms such as "installation", "connection", and "fixing" should be interpreted broadly, and can refer to direct connection, installation or fixing, or indirect connection, installation or fixing, and the present invention does not impose any limitation in this regard.

[0028] like Figures 1 to 5 As shown in the schematic diagram, this utility model discloses an embodiment of an aerial work platform for protective construction of multi-story pipe corridors. It includes a platform body, a first fixing unit, and a second fixing unit. The platform body includes multiple spaced-apart bent support frames 1, each with a protrusion for crossing pipes 17. The first and second fixing units are respectively connected to both ends of the bent support frames 1 for fixation. The first and second fixing units can be connected to pipe corridor columns 10 to suspend the platform body. The recessed portion of the bent support frame 1 is adaptable to existing pipe corridor steel structures 18, which in turn support the bent support frame 1, ensuring the stability of the aerial work platform and construction safety.

[0029] In this embodiment, the first fixing unit includes multiple first column connecting parts 2 and a first support frame 3 for connecting adjacent first column connecting parts 2. The first end of the bent support frame 1 is connected to the corresponding first column connecting part 2 or the first support frame 3. The second fixing unit includes multiple second column connecting parts 4 and a second support frame 5 for connecting adjacent second column connecting parts 4. The second end of the bent support frame 1 is connected to the corresponding second column connecting part 4 or the second support frame 5. Preferably, the first column connecting parts 2 and the second column connecting parts 4 are detachable rectangular frames that can be fastened to the pipe gallery columns 10.

[0030] In this embodiment, a connecting unit is also included. The connecting unit includes multiple connecting pipes 6 and bolts 7. The end of the bent support frame 1 is movably sleeved with the connecting pipe 6 and fixed by the bolts 7. The connecting pipe 6 is connected to the corresponding first fixing unit or second fixing unit. Preferably, multiple connecting pipes 6 are respectively arranged on both sides of the bent support frame 1 and the number is adapted. The first fixing unit or second fixing unit is fixedly connected to the corresponding connecting pipe 6. The fixing method can be welding or the like. The two ends of the bent support frame 1 are respectively connected to the corresponding connecting pipe 6 one by one for detachable connection.

[0031] Multiple adjustment holes 61 are provided on the connecting pipe 6 or the bent support frame 1, and bolts 7 are installed in the corresponding adjustment holes 61. The connection position between the connecting pipe 6 and the bent support frame 1 can be adjusted through the multiple adjustment holes 61, so that the bent support frame 1 can be movably installed between the first fixed unit and the second fixed unit with different spacing, forming a telescopic aerial work platform to cross different pipe outer diameters or to be suitable for complex pipeline 17 construction environments. In one embodiment, multiple adjustment holes 61 are provided on the connecting pipe 6, and limiting holes are provided at the corresponding connection ends of the bent support frame 1 and the connecting pipe 6, and the limiting holes can correspond to the adjustment holes 61; in another embodiment, limiting holes are provided on the connecting pipe 6, and multiple adjustment holes 61 for telescopic adjustment are provided at the connection ends of the bent support frame 1 and the connecting pipe 6. In this embodiment, both ends of the bent support frame 1 are connection ends to be movably connected to the corresponding connecting pipes 6 on both sides.

[0032] In this embodiment, the platform body also includes multiple reinforcing rods 8, which are connected to multiple bent support frames 1. Preferably, each reinforcing rod 8 is vertically connected to the bent support frame 1 to form a grid-like support structure.

[0033] In this embodiment, the first fixing unit and the second fixing unit are at least partially provided with lifting lugs 9. Preferably, both the first support frame 3 and the second support frame 5 are provided with lifting lugs 9 to facilitate hoisting.

[0034] The platform body, the first fixing unit, and the second fixing unit are at least partially telescopic structures. Preferably, in this embodiment, the first support frame 3, the second support frame 5, and the reinforcing rod 8 are all telescopic structures. The telescopic structure can adopt an inner sleeve and an outer sleeve that are nested together, and at least one of them has multiple adjustment holes 61 and is locked with bolts 7. Multiple first column connecting parts 2, second column connecting parts 4, inner sleeves, outer sleeves, connecting pipes 6, and bent support frames 1 are correspondingly connected to form an adjustable working platform that can extend and retract in two mutually perpendicular directions.

[0035] In this embodiment, the bent support frame 1 has a Z-shaped structure, comprising a first horizontal bar 11, a vertical bar 12, and a second horizontal bar 13 connected vertically in sequence. The first horizontal bar 11 is movably connected to the corresponding first support frame 3 or the first column connection part 2 via a connecting pipe 6. The second horizontal bar 13 is movably connected to the corresponding second support frame 5 or the second column connection part 4 via a connecting pipe 6. The first horizontal bar 11 and the vertical bar 12 form a protrusion with an opening facing downwards to cross the pipe 17, and the second horizontal bar 13 forms a corresponding recess to be erected on the existing pipe gallery steel structure 18. In other embodiments, the bent support frame 1 is not limited to a Z-shape and may have alternating protrusions and recesses. In this embodiment, the first fixing unit further includes a third column connecting part 14, a third support frame 15, and a strut 16. The third column connecting part 14 is located below the first column connecting part 2 and is connected by the strut 16 to reinforce the installation on the corresponding pipe gallery column 10. The third column connecting part 14 and the strut 16 can better support the first column connecting part 2 and connect the first column connecting part 2 to the protrusion of the bent support frame 1, ensuring the structural rigidity of the bent support frame 1 across the pipe 17, avoiding damage to the existing pipe 17, and also improving the anti-overturning ability to ensure the safety of high-altitude operations. The third column connecting part 14 has the same structure as the first column connecting part 2, and the third support frame 15 has the same structure as the first support frame 3 and is a telescopic structure.

[0036] The construction process of this utility model includes the following steps:

[0037] On-site, galvanized square steel pipes are spliced ​​into rectangular column connection frames to prepare the first column connection part 2, the second column connection part 4, or the third column connection part 14. The first column connection part 2 and the third column connection part 14 correspond one-to-one and are connected by support rods 16. Adjacent first column connection parts 2 are connected by telescopic first support frame 3, adjacent third column connection parts 14 are connected by telescopic third support frame 15, and adjacent second column connection parts 4 are connected by telescopic second support frame 5. The connecting pipe 6 is fixed to the corresponding first column connection part 2, first support frame 3, second column connection part 4, or second support frame 5 by welding.

[0038] First, connect the first fixed unit to the corresponding pipe gallery column 10 on one side of the pipe 17;

[0039] Next, the bent support frame 1 is hoisted in sequence, and the bent support frame 1 is connected to the first fixed unit. The splicing length of the bent support frame 1 and the connecting pipe 6 is adjusted. The span of the protrusion is checked to see if it is greater than the width of the corresponding existing pipe 17, so that the bent support frame 1 can be erected on the steel structure 18 of the pipe gallery and cross the pipe 17 through the protrusion. After the splicing position is determined, it is fixed with bolts 7.

[0040] The second fixing unit is hoisted and installed on the corresponding pipe gallery column 10 on the other side of the pipe 17 and connected to the bent support frame 1. The main body of the platform is suspended through the first fixing unit and the second fixing unit. The pipe gallery column 10 and the aerial work platform can also be connected by tie rods.

[0041] The platform body can serve as a foundation for the continued construction of the frame above pipe 17, and a base plate can also be laid on the platform body to form a working surface for manual operations.

[0042] In this embodiment, a high-altitude work platform frame can be formed by welding square steel pipes and then interconnected to form a telescopic structure, reducing the difficulty of construction and improving construction efficiency. The first and second fixed units are respectively connected to the pipe gallery columns 10, and the bent support frame 1 can use the pipe gallery steel structure 18 as an auxiliary support to ensure the stability and safety of the high-altitude work platform. The protrusion of the bent support frame 1 reserves space for existing pipes to cross the pipes, protecting the existing pipes from damage without dismantling or modifying the existing pipe gallery structure. The telescopic structure with interlocking allows for dynamic adjustment of the span, suitable for different pipe diameters or complex pipe gallery environments. The modular hoisting and recombining method reduces the difficulty of large-scale operations. The work platform suspended in the air can serve as a construction support foundation for continuing to build the upper frame structure or laying a base plate as a manual walking platform. Compared with the traditional method of building a full-span scaffold from the ground, the suspended high-altitude work platform can avoid occupying the lower space of the pipe 17, avoid the problem of blocking ground passages, and ensure that other processes can be carried out simultaneously.

All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
