Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, and in particular to a working platform attached to a steel pipe column. Background Technology

[0002] In large-scale bridge construction projects, large-scale temporary support scaffolds made of steel pipes are typically erected to complete the erection of cast-in-place concrete beams or steel beams. These scaffolds are tall, and the on-site connection of the steel pipe columns, weld inspection, and subsequent maintenance all fall under the category of high-altitude work, requiring a stable and safe working surface for construction personnel.

[0003] In traditional construction, simple suspended scaffolds are often used as high-altitude work platforms, where a crane lifts the scaffold carrying personnel to the work location. However, this method suffers from poor stability when the scaffold is suspended in the air, making it prone to swaying and overturning, posing a significant risk of personnel falling from heights and serious safety hazards. Furthermore, it requires the crane to occupy the equipment for extended periods, leading to shortages of critical equipment resources, reduced scheduling efficiency, and the time-consuming lifting process directly hinders the overall construction progress, impacting project efficiency and economy.

[0024] like Figures 1-4 As shown, a working platform attached to a steel pipe column includes a bracket assembly 1, a platform frame 2, a platform panel 3, a ladder assembly 4, and a guardrail assembly 5. The bracket assembly 1 is connected to the steel pipe column 7 to provide load-bearing support; the platform frame 2 is connected to the top of the bracket assembly 1; the platform panel 3 is fixed inside the platform frame 2; the upper part of the ladder assembly 4 is connected to the platform frame 2, and its lower part is fixedly connected to the steel pipe column 7 through a connecting rod 6; the guardrail assembly 5 is connected to the periphery of the platform frame 2.

[0025] In this embodiment, the bracket assembly 1 is directly connected to the steel pipe column 7 and provides stable load-bearing support. Together with the platform frame 2 connected to the top and the platform panel 3 fixed inside the frame, a stable working base rigidly connected to the steel pipe column 7 is formed, solving the problem of easy swaying and overturning in traditional suspended platform operations and significantly reducing the risk of personnel falling from heights. The ladder assembly 4 is connected to the platform frame 2 at the top and fixed to the steel pipe column 7 at the bottom through the connecting rod 6, forming an independent and stable personnel access channel. It does not require the use of lifting equipment to transport personnel, effectively reducing the time occupied by lifting equipment and avoiding the problems of tight resources and low scheduling efficiency of key equipment. At the same time, it eliminates the time-consuming process of hoisting the suspended platform, significantly accelerating the overall construction progress. The guardrail assembly 5 connected to the platform frame 2 further strengthens the safety line. Together with the rigid connection structure of each component, it not only ensures the safety of construction personnel but also simplifies the installation process and improves the convenience of construction.

[0026] Specifically, the platform panel 3 is made of steel plate, and the edge of the platform panel 3 is connected to the platform frame 2.

[0027] like Figure 1 and Figure 2 As shown, the bracket assembly 1 includes a horizontally arranged bracket crossbar 101 and an inclined bracket diagonal bar 102. One end of the bracket crossbar 101 is connected to the steel pipe column 7, one end of the bracket diagonal bar 102 is connected to the bottom of the bracket crossbar 101, and the other end of the bracket diagonal bar 102 is connected to the steel pipe column 7.

[0028] In this embodiment, the horizontally arranged bracket crossbar 101 is directly connected at one end to the steel pipe column 7, providing a flat and rigid support base for the upper platform frame 2. This avoids the problem of base surface swaying during traditional suspended platform operations and ensures the flatness of the platform panel 3 after its installation. The inclined bracket diagonal bar 102 is connected at one end to the bottom of the bracket crossbar 101 and fixed at the other end to the steel pipe column 7. This not only effectively distributes the vertical load borne by the bracket crossbar 101 but also evenly transfers the load to the steel pipe column 7, preventing the bracket from... The crossbar 101 deformed due to excessive local stress, but the stability characteristics of the triangular structure significantly improved the overturning resistance of the entire working platform. At the same time, the combined structure of the corbel crossbar 101 and the corbel diagonal bar 102 does not require the use of lifting equipment for auxiliary support, reducing the occupation of lifting equipment. Moreover, the structure itself is easy to install and can be quickly connected and fixed to the steel pipe column 7, which helps to speed up the construction progress. Compared with the traditional suspended platform hoisting and construction method, it not only improves the structural load-bearing reliability, but also takes into account the construction economy and efficiency.

[0029] There are four corbel crossbars 101 and four corbel diagonal braces 102, which are circumferentially welded to the steel pipe column 7 at equal intervals.

[0030] like Figure 1 and Figure 2 As shown, the platform frame 2 includes an outer ring crossbar 201 and an inner ring crossbar 202. Multiple reinforcing bars 203 are connected between the outer ring crossbar 201 and the inner ring crossbar 202. Both the outer ring crossbar 201 and the inner ring crossbar 202 are connected to the top of the corbel crossbar 101.

[0031] In this embodiment, the inner ring crossbar 202 is connected to the top of the corbel crossbar 101, which can closely fit the outer side of the steel pipe column 7 to form the inner support boundary, providing a precise inner installation reference for the platform panel 3, while enhancing the connection tightness between the frame and the load-bearing foundation, and avoiding misalignment of the working surface; the outer ring crossbar 201 is simultaneously connected to the top of the corbel crossbar 101, which not only defines the outer range of the working platform and provides a stable installation carrier for the subsequent guardrail assembly 5, but also forms an inner and outer double frame structure with the inner ring crossbar 202, which greatly improves the overall resistance to lateral deformation of the platform; the outer ring crossbar 201 and the inner ring crossbar 101 form a double frame structure, which greatly improves the overall resistance to lateral deformation of the platform; the outer ring crossbar 201 and the inner ring crossbar 102 form a double frame structure, which enhances the connection tightness between the frame and the load-bearing foundation, and prevents misalignment of the working surface. Multiple reinforcing bars 203 connecting the horizontal bars 202 can firmly connect the inner and outer ring frames into one, so that the force after the platform panel 3 is laid is evenly distributed to each corbel horizontal bar 101, avoiding structural damage caused by localized force concentration. Compared with the traditional single suspended load method of the suspended platform, this frame structure has a stronger load-bearing capacity and higher stability. Moreover, it does not require the assistance of lifting equipment for construction. During installation, it can be quickly assembled directly based on the corbel component 1, reducing the time occupied by lifting equipment. This not only ensures the safety of construction personnel working on the platform panel 3, but also improves the construction efficiency, taking into account both project stability and economy.

[0032] Specifically, the outer ring crossbar 201 is located outside the inner ring crossbar 202.

[0033] like Figure 1 and Figure 4 As shown, the ladder assembly 4 includes two vertical plates 41, with multiple steps 42 connected between the two vertical plates 41. A protective frame 43 is connected to the outside of the vertical plates 41. The upper part of the vertical plates 41 is connected to the platform frame 2 through the ladder side crossbar 44, and the lower part of the vertical plates 41 is connected to the steel pipe column 7 through the connecting rod 6.

[0034] In this embodiment, multiple footrests 42 connected between two symmetrically arranged vertical plates 41 form a uniformly distributed and stable stepping surface, ensuring balanced force on the feet of construction workers during the climbing process. The protective frame 43 connected to the outside of the vertical plates 41 can prevent personnel from losing balance and tipping over during climbing, effectively avoiding the risk of falling from height. The upper part of the vertical plates 41 is firmly connected to the platform frame 2 through the ladder side crossbars 44, and the lower part is fixed to the steel pipe column 7 through the connecting rods 6, forming a stable structure with rigid fixation at both the top and bottom points. This eliminates the problem of swaying in the air, similar to traditional suspended baskets, and further improves the safety of passage. At the same time, this ladder component can be installed and used without the aid of lifting equipment. Personnel can independently climb the ladder to and from the work platform, greatly reducing the time occupied by lifting equipment and avoiding the problem of tight equipment scheduling.

[0035] like Figure 1 and Figure 3As shown, the guardrail assembly 5 includes multiple protective vertical bars 51 and multiple protective horizontal bars 52. The bottom end of the protective vertical bars 51 is connected to the platform frame 2. Multiple mounting holes 53 are opened in the vertical direction of the protective vertical bars 51. Multiple protective horizontal bars 52 are detachably connected to the mounting holes 53 of the protective vertical bars 51 by bolts.

[0036] In this embodiment, the bottom end of the protective vertical bar 51 is firmly connected to the platform frame 2 to form a uniformly distributed vertical protective support, constructing the first safety barrier around the work platform and effectively preventing construction personnel from accidentally falling outwards. Multiple protective horizontal bars 52 cooperate with the protective vertical bars 51 to form a complete crisscross protective net, further reducing the protective gaps and preventing personnel limbs or construction tools from falling from the edge of the platform. At the same time, they provide reliable handrail support for workers and enhance their physical stability during operation. Multiple mounting holes 53 opened vertically in the protective vertical bar 51 allow the protective horizontal bars 52 to be detachably connected and height adjusted by bolts. This not only allows for flexible adjustment of the protective height according to the construction scenario to adapt to different operational needs, but also facilitates component transportation, rapid on-site assembly, and subsequent maintenance and replacement.

[0037] like Figure 2 and Figure 4 As shown, the ladder side crossbar 44 is connected to the platform frame 2 via the fixing rod 8, and the bottom of the ladder side crossbar 44 is connected to the top of the bracket assembly 1.

[0038] In this embodiment, the side crossbar 44 of the ladder is connected to the platform frame 2 through the fixing rod 8, forming a secondary reinforcement connection between the ladder assembly 4 and the platform frame 2, avoiding lateral swaying caused by the ladder being only connected at a single point; the bottom of the side crossbar 44 of the ladder is connected to the top of the bracket assembly 1, and the stable triangular load-bearing structure of the bracket assembly 1 itself provides a solid bottom support for the ladder, forming a double stable structure, which greatly improves the load-bearing capacity of the ladder and can stably bear the weight of construction personnel and tools.

[0039] like Figure 4 As shown, multiple safety rope fixing rings 9 are fixed inside the protective frame 43.

[0040] In this embodiment, the protective frame 43 itself provides lateral anti-tipping protection for the climbing ladder assembly 4. The safety rope fixing ring 9 fixed inside provides a dedicated and stable safety rope suspension point for construction workers when climbing. Construction workers can tie one end of the safety rope to themselves and hang the other end on the safety rope fixing ring 9, which greatly reduces the risk of accidental falls.

[0041] Working principle: First, weld one end of the horizontal bracket crossbar 101 in the bracket assembly 1 to the steel pipe column 7. Then, connect the bottom of the bracket crossbar 101 to the steel pipe column 7 through the inclined bracket diagonal bar 102 to form a stable triangular load-bearing foundation. Subsequently, fix the platform frame 2, which consists of the outer ring crossbar 201, the inner ring crossbar 202, and the reinforcing bar 203, to the top of the bracket crossbar 101. Lay and fix the platform panel 3 inside the platform frame 2 to create a flat high-altitude work base. Simultaneously assemble the climbing ladder assembly 4, using two vertical plates 41 as the supporting base, connecting the steps 42 between them to form a climbing passage. Fix the protective frame 43 to the outside of the vertical plates 41 and install safety ropes on the inside for fixation. The upper part of the ring 9 and the vertical plate 41 are connected to the platform frame 2 via the ladder side crossbar 44 and the fixing rod 8, and the lower part is fixed to the steel pipe column 7 via the connecting rod 6. The bottom of the ladder side crossbar 44 is connected to the top of the bracket assembly 1 to enhance stability. Finally, the guardrail assembly 5 is installed on the outside of the platform frame 2, and the bottom end of the protective vertical bar 51 is fixed to the platform frame 2. The protective horizontal bar 52 is detachably connected with bolts through the mounting holes 53 on the protective vertical bar 51 to form a complete protection system. During operation, the construction personnel hang the safety rope on the safety rope fixing ring 9, climb to the platform panel 3 through the ladder assembly 4, and carry out high-altitude operations within the protection range of the guardrail assembly 5. The entire process does not require hoisting equipment.

[0042] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
