Description

Technical Field

[0001] This application relates to the field of engineering construction technology, and in particular to a prefabricated arch rib segment docking operation platform. Background Technology

[0002] Steel pipe arch bridges are widely used in bridge engineering due to their superior span performance, durability, and relatively low maintenance costs. These bridges are typically constructed using a segmental construction method, with welding between adjacent arch rib segments being a critical process. Currently, welding at the joints between adjacent arch rib segments is done manually. Before installing the next arch rib segment, staggered members are usually welded onto the previous segment to form a simple working platform for workers to stand on and perform the work.

[0003] In related technologies, the construction of welding platforms for steel pipe arch bridges is mainly achieved through the following two methods: First, staggered members are welded onto the installed arch rib segments to temporarily assemble a platform for construction workers to stand on; second, the web members of the arch rib segments themselves are used as support points, and members are erected upwards to the docking position before the platform is laid. Both of these methods require reconstruction before each new segment is erected, and the platform structure lacks stability, making it difficult to adapt to the dynamic high-altitude construction environment.

[0004] Existing welding platforms have significant drawbacks: firstly, manual on-site erection consumes substantial manpower and time, and material reuse is low, leading to high construction costs; secondly, the platform structure is rudimentary, lacking effective anti-tipping design, and is prone to accidents due to insufficient stability during high-altitude operations. Furthermore, the protective measures of temporary platforms are weak, posing a fall risk to construction workers during welding, severely restricting the safety and efficiency of steel pipe arch bridge construction. Therefore, there is an urgent need for a structurally stable, quickly assembled and disassembled prefabricated work platform with comprehensive safety protection to solve the above technical problems and improve construction reliability. Summary of the Invention

[0005] To address any of the shortcomings or deficiencies mentioned in the background technology, this application provides a prefabricated arch rib segment docking operation platform. It adopts a prefabricated design, which is convenient for assembly and disassembly, and can ensure the quality of the operation platform and protect the safety of the operators.

[0006] This application provides a prefabricated arch rib segment docking platform, including: The platform steel frame includes a crossbeam, and at least two downwardly inclined cantilever arms are spaced apart along the length of the crossbeam. The end of each cantilever arm away from the crossbeam is fixedly connected to a base frame. A detachable assembly includes a support rod and a connecting frame. The support rod connects to the adjacent cantilever, and the connecting frame connects to the adjacent base frame. A space is formed between the support rod and the crossbeam for the passage of the arch rib segment. The connecting frame and the base frame together constitute an operating platform.

[0007] In some embodiments, the cantilever is a staircase structure, which includes two inclined rods arranged at intervals. The two ends of each inclined rod are respectively fixedly connected to a crossbeam and a base frame, and a plurality of foot pedals are fixedly connected between the two inclined rods and distributed at intervals along the length of the inclined rods.

[0008] In some embodiments, a connecting plate is fixedly connected to one side of the tilting rod, and a through hole is provided on the connecting plate. The support rod is fixedly connected to the connecting plate by bolts.

[0009] In some embodiments, the two ends of the connecting frame overlap with the adjacent base frame, and the overlapping parts of the connecting frame and the base frame are fixedly connected by bolts.

[0010] In some embodiments, the base frame is equipped with edge guardrails connected to the cantilever, and safety ropes are connected between adjacent edge guardrails.

[0011] In some embodiments, the edge guardrail includes a post fixed to the base frame, a steel pipe handrail fixedly connected to the post, and the end of the safety rope passing through and fixed inside the steel pipe handrail.

[0012] In some embodiments, the crossbeam includes two symmetrically arranged channel steels, which are fixedly connected to each other to form a rectangular cross section, and stiffening plates for connecting arch rib segments are fixedly connected to opposite sides of the two channel steels.

[0013] In some embodiments, the base frame includes a frame fixedly connected to the cantilever, and a first support rod fixed within the side frame; The connecting frame includes two horizontal bars arranged at intervals, each horizontal bar having its two ends connected to the adjacent frame, and a plurality of second support bars fixedly connected between adjacent horizontal bars at intervals along the length of the horizontal bars.

[0014] In some embodiments, an elongated hole is provided on the frame or the crossbar, and a bolt for connecting the frame and the crossbar passes through the elongated hole.

[0015] In some embodiments, a first steel mesh supported on the first support rod is laid on the frame, and a second steel mesh supported on the second support rod is laid between the two crossbars.

[0016] The beneficial effects of the technical solution provided in this application include: This application provides a prefabricated arch rib segment docking operation platform. Due to the presence of a platform steel frame and detachable components, the platform steel frame includes a crossbeam, on which at least two downwardly inclined cantilever arms are spaced apart along the length direction. The end of each cantilever arm away from the crossbeam is fixedly connected to a base frame. The detachable components include a support rod and a connecting frame. The support rod connects to adjacent cantilever arms, and the connecting frame connects to adjacent base frames. A space for the arch rib segment to pass through is formed between the support rod and the crossbeam. The connecting frame and the base frame together constitute the operating platform.

[0017] Therefore, the construction process can be significantly simplified, the operating platform can be quickly constructed, and stable support can be provided for welding operations. The support rods connect adjacent cantilever sections and simultaneously form a support relationship with the arch rib segments, effectively preventing the cantilever sections from tilting or overturning due to uneven stress during construction. After the platform is used, the support rods and connecting frames are disassembled, and the welded joints between the crossbeams and the arch rib segments are separated, allowing the entire steel frame of the platform to be lifted away.

[0018] The prefabricated design of this application offers significant advantages. Pre-fabrication of the platform's steel frame on the ground ensures the geometric accuracy and welding quality of each component, avoiding the accumulation of errors inherent in on-site manual assembly. The detachable components can be reused as standardized parts, significantly reducing material waste and minimizing time spent working at heights, effectively mitigating the risk of falls for construction workers. Furthermore, the modular nature of the detachable components allows the platform to quickly adapt to the needs of arch rib segments with different spans, further enhancing construction flexibility and turnover efficiency.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] To address any of the shortcomings or deficiencies mentioned in the background technology, this application provides a prefabricated arch rib segment docking operation platform. It adopts a prefabricated design, which is convenient for assembly and disassembly, and can ensure the quality of the operation platform and protect the safety of the operators.

[0024] See Figures 1 to 5 As shown in the figure, this application provides a prefabricated arch rib segment docking operation platform, including: The platform steel frame includes a crossbeam 1, and at least two downwardly inclined cantilever 2 are provided on the crossbeam 1 at intervals along the length direction. The end of each cantilever 2 away from the crossbeam 1 is fixedly connected to a base frame 3. The detachable component includes a support rod 4 and a connecting frame 5. The support rod 4 connects to the adjacent cantilever 2, and the connecting frame 5 connects to the adjacent base frame 3. A space is formed between the support rod 4 and the crossbeam 1 for the arch rib segment 100 to pass through. The connecting frame 5 and the base frame 3 together constitute the operating platform.

[0025] This application embodiment separates the platform steel frame from the detachable components, significantly simplifying the construction process. The platform steel frame can be standardized and processed in a steel structure processing plant, forming an integral structure, and then transported to the site. It is then hoisted to the end of the arch rib segment 100 by a crane, and the crossbeam 1 is welded and fixed to the main chord of the arch rib segment 100 to ensure structural stability.

[0026] Subsequently, the installation of the support rod 4 and the connecting frame 5 can further optimize construction efficiency. The support rod 4 connects to the adjacent cantilever 2 and forms a supporting relationship with the arch rib segment 100, effectively preventing the cantilever 2 from tilting downwards and overturning due to uneven force during construction. The connecting frame 5 connects to the adjacent base frame 3 to quickly build an operating platform and provide stable support for welding operations.

[0027] After the platform is no longer in use, the disassembly process is equally efficient. The fixed connection between the connecting frame 5 and the base frame 3 is disconnected in sequence, as is the connection between the support rod 4 and the cantilever 2. Then, the welded parts between the crossbeam 1 and the arch rib segment 100 are separated by cutting equipment, and the platform steel frame can be lifted off as a whole by a crane.

[0028] The advantages of this prefabricated design are twofold: firstly, in-factory processing ensures the geometric accuracy and welding quality of each component, avoiding the accumulation of errors from on-site manual assembly; secondly, the reusability of standardized components significantly reduces material waste and minimizes time spent working at heights, effectively mitigating the risk of workers falling. Furthermore, the modular nature of the detachable components allows the platform to quickly adapt to the needs of arch rib segments with different spans, further enhancing construction flexibility and turnover efficiency.

[0029] For example, in this embodiment, one end of the cantilever 2 is fixed to the crossbeam 1 by welding, and the other end is fixed to the base frame 3 by welding. The cantilever 2 is arranged perpendicularly to the crossbeam 1, and the base frame 3 is arranged horizontally and forms an obtuse angle with the cantilever 2. There are three cantilever 2s. The support rods 4 that are fixedly connected between adjacent cantilever 2s by bolts abut against the arch rib segment 100, and the connecting frames 5 that are fixedly connected between adjacent base frames 3s by bolts form an operating platform.

[0030] In other embodiments, the support rod 4 and the cantilever 2, and the connecting frame 5 and the base frame 3 can be connected by snap-fit ​​or quick-release pin structure to achieve detachable connection, so as to improve assembly efficiency and reduce construction difficulty.

[0031] In some alternative embodiments: see Figures 1 to 5 As shown, this application embodiment provides a prefabricated arch rib segment docking operation platform. The cantilever 2 of the prefabricated arch rib segment docking operation platform is a step ladder structure. The step ladder structure includes two inclined rods 21 arranged at intervals. The two ends of each inclined rod 21 are respectively fixedly connected to the crossbeam 1 and the base frame 3. Multiple foot pedals 22 are fixedly connected between the two inclined rods 21 and distributed at intervals along the length direction of the inclined rods 21.

[0032] The staircase structure in this embodiment is fixed to the crossbeam 1 and the base frame 3 by welding two inclined rods 21 together, and combined with foot pedals 22 spaced apart along the length of the inclined rods 21, forming a stable trapezoidal frame. The trapezoidal frame facilitates construction workers to climb and approach the arch rib segment 100, making it convenient for construction workers to perform welding operations at the joints of the arch rib segment 100.

[0033] In addition, the trapezoidal frame structure design not only improves the stability of construction workers climbing, but also, through the force distribution characteristics of the inclined rod 21, can transfer the force to the arch rib segment 100 through the support rod 4, effectively dispersing the load and reducing the risk of the staircase structure overturning due to uneven force distribution.

[0034] For example, in this embodiment, the inclined bar 21 is made of channel steel and the foot bar 22 is made of angle steel. The top surface of the angle steel is arranged horizontally to facilitate stepping. At the same time, the angle steel is spaced apart to further enhance the local load-bearing capacity of the work platform and facilitate the safe movement of construction personnel in high-altitude environments.

[0035] In some alternative embodiments: see Figures 1 to 5 As shown in the figure, this application embodiment provides a prefabricated arch rib segment docking operation platform. A connecting plate 23 is fixedly connected to one side of the inclined rod 21 of the prefabricated arch rib segment docking operation platform. A through hole is opened on the connecting plate 23. The support rod 4 is fixedly connected to the connecting plate 23 by bolts.

[0036] In this embodiment, the connecting plate 23 provides a standardized interface for connecting the support rod 4 and the cantilever 2 through the cooperation of through holes and bolts. This design, while maintaining the overall structural integrity, enables the rapid assembly and disassembly of the support rod 4, avoiding the low construction efficiency caused by traditional welding methods.

[0037] For example, the connecting plate 23 is strip-shaped, and multiple through holes are provided on the connecting plate 23 at intervals along the length of the inclined rod 21. By matching the through holes at different positions with the support rod 4, it can be ensured that the support rod 4 supports the arch rib segment 100 with different inclination angles, so that the platform can quickly adapt to the arch rib segment 100 with different spans, thereby improving construction flexibility and efficiency.

[0038] In some alternative embodiments: see Figures 1 to 5 As shown, this application embodiment provides a prefabricated arch rib segment docking operation platform. The two ends of the connecting frame 5 of the prefabricated arch rib segment docking operation platform are respectively attached to the adjacent base frame 3, and the overlapping parts of the connecting frame 5 and the base frame 3 are fixedly connected by bolts.

[0039] In this embodiment, the connecting frame 5 overlaps at both ends and is fixedly connected by bolts, forming a detachable lateral support system. This overlapping structure reduces the need for on-site welding while ensuring the coordinated stress distribution between the base frame 3 and the connecting frame 5 through the rigid connection of bolts, preventing deformation of the operating platform due to loose connections. The bolt fixing method at the overlapping part also facilitates quick separation during subsequent disassembly, reducing the construction cycle.

[0040] In some alternative embodiments: see Figures 1 to 5As shown, this application embodiment provides a prefabricated arch rib segment docking operation platform. The base frame 3 of the prefabricated arch rib segment docking operation platform is equipped with edge guardrails 6 connected to the cantilever 2, and safety ropes 7 are connected between adjacent edge guardrails 6.

[0041] In this embodiment, the edge guardrail 6, through its fixed connection with the base frame 3 and cantilever 2, constructs a protective system surrounding the work area. Adjacent edge guardrails 6 are secured together by safety ropes 7, forming a continuous safety barrier that effectively prevents construction workers from accidentally falling. The elastic cushioning characteristics of the safety ropes 7 can adapt to dynamic load changes during construction.

[0042] In some alternative embodiments: see Figures 1 to 5 As shown, this application embodiment provides a prefabricated arch rib segment docking operation platform. The edge guardrail 6 of the prefabricated arch rib segment docking operation platform includes a column 61 fixed on the base frame 3. A steel pipe handrail 62 is fixedly connected to the column 61. The end of the safety rope 7 is threaded through and fixed inside the steel pipe handrail 62.

[0043] In this embodiment, the steel pipe handrail 62 is fixedly connected to the base frame 3 via the column 61, providing a reliable anchor point for the safety rope 7. The end of the safety rope 7 is threaded through and fixed inside the steel pipe handrail 62, ensuring both the rigid connection of the protective structure and preventing wear and breakage of the safety rope 7 during long-term use due to the tensile strength characteristics of the steel pipe.

[0044] For example, the edge guardrail 6 is pre-welded and fixed to the base frame 3 in the factory on the ground. The safety rope 7 is made of steel rope. The end of the steel pipe handrail 62 is threaded with multiple bolts. The steel rope is fixed by radially pressing the bolts, thereby realizing the detachable connection of the steel rope, which facilitates quick separation during subsequent disassembly and reduces the construction cycle.

[0045] In some alternative embodiments: see Figures 1 to 5 As shown, this application embodiment provides a prefabricated arch rib segment docking operation platform. The crossbeam 1 of the prefabricated arch rib segment docking operation platform includes two symmetrically arranged channel steels. The two channel steels are fixedly connected to each other to form a rectangular cross section. Stiffening plates 8 for connecting arch rib segments 100 are fixedly connected to the opposite sides of the two channel steels respectively.

[0046] In this embodiment, the crossbeam 1 consists of two symmetrically arranged channel steels. The channel steels are connected by welding or bolts to form a rectangular cross-section, which significantly improves the bending load-bearing capacity of the crossbeam 1. The stiffening plate 8 on the back side of the channel steel is welded to the outer wall of the arch rib segment 100, which not only enhances the connection strength between the crossbeam 1 and the arch rib segment 100, but also reduces the impact of welding thermal stress on the structure through local stiffening design, thus extending the service life of the platform.

[0047] In some alternative embodiments: see Figures 1 to 5 As shown, this application embodiment provides a prefabricated arch rib segment docking operation platform. The base frame 3 of the prefabricated arch rib segment docking operation platform includes a frame 31 fixedly connected to the cantilever 2, and a first support rod 32 fixed inside the frame 31. The connecting frame 5 includes two horizontal bars 51 arranged at intervals. The two ends of each horizontal bar 51 are connected to the adjacent frame 31 respectively. A plurality of second support bars 52 are fixedly connected between the adjacent horizontal bars 51 and distributed at intervals along the length of the horizontal bars 51.

[0048] In this embodiment, the base frame 3, through the combination of the frame 31 and the first support rod 32, and the spaced fixing of the crossbar 51 and the second support rod 52 in the connecting frame 5, constructs a planar support structure. Specifically, the frame 31 and the crossbar 51 are fixedly connected by fasteners, the two ends of the first support rod 32 are welded and fixed to the base frame 3, and the two ends of the second support rod 52 are respectively welded and fixed to the crossbars 51 on both sides, ensuring the stability of the work platform during dynamic construction.

[0049] In some alternative embodiments: see Figures 1 to 5 As shown, this application embodiment provides a prefabricated arch rib segment docking operation platform. The prefabricated arch rib segment docking operation platform has an elongated hole 311 on the frame 31 or the crossbar 51, and a bolt for connecting the frame 31 and the crossbar 51 is inserted into the elongated hole 311.

[0050] In this embodiment, the elongated hole 311 provides adjustable space for the connection between the frame 31 and the crossbar 51, reducing the installation precision required for the overlap and matching of the frame 31 and the crossbar 51, and enabling rapid alignment and installation. Bolts are inserted into the elongated hole 311, locking the frame 31 and the crossbar 51 together through tightening. Simultaneously, it allows construction personnel to fine-tune the position of the crossbar 51 according to site conditions, ensuring that the crossbar 51 and the frame 31 quickly fit and match.

[0051] In some alternative embodiments: see Figures 1 to 5 As shown, this application embodiment provides a prefabricated arch rib segment docking operation platform. The frame 31 of the prefabricated arch rib segment docking operation platform is covered with a first steel plate mesh 9 supported on a first support rod 32, and a second steel plate mesh 10 supported on a second support rod 52 is laid between two crossbars 51.

[0052] In this embodiment, the steel mesh, supported by the first support rod 32 and the second support rod 52, covers the entire working surface of the operating platform. The laying of the first steel mesh 9 enhances the anti-slip performance of the base frame 3, preventing construction workers from slipping during welding. The second steel mesh 10, supported by the crossbar 51 and the support rod, further optimizes the load-bearing capacity of the connecting frame 5, while reducing wind resistance through the mesh structure, thus improving the safety of high-altitude operations. For example, the first steel mesh 9 can be pre-welded and fixed to the frame 31, and the second steel mesh 10 can be pre-welded and fixed to the crossbar 51.
