[0033] When constructing bridge cylindrical piers, a working platform needs to be erected on top of each pier section to facilitate tasks such as surveying and setting out, rebar tying, installation and dismantling of pier formwork, and concrete pouring. Traditionally, scaffolding platforms are erected around the cylindrical pier to provide working surfaces for workers. However, the scaffolding structure is complex, requiring construction around the curved contour. Conventional right-angle couplers and standardized horizontal bars cannot be used; custom-made curved members must be installed according to the diameter of the cylindrical pier, or the angle of each upright must be adjusted individually. Erection and dismantling of these scaffolding platforms consume a significant amount of manpower and time, severely impacting construction efficiency.

[0034] Therefore, such as Figures 1 to 4As shown, the cylindrical pier working platform proposed in this utility model includes: multiple mounting frames 100, platform components 200, and protective components 300. The mounting frames 100 are spaced apart along the outer periphery of the cylindrical pier, forming a stable support. Each mounting frame 100 is connected to a fixing member 110 for fixed connection to the cylindrical pier. The platform component 200 has a ring-shaped structure, with a central accommodating space where the cylindrical pier is placed. The platform component 200 is fixedly connected to the mounting frames 100. The protective components 300 are connected to the mounting frames 100 and located on the side of the mounting frames 100 away from the cylindrical pier. The protective components 300 can form a ring structure, connecting the multiple mounting frames 100 in series. The overall structure of the working platform is simple, eliminating the need for cumbersome on-site assembly with curved rods and the need for customized non-standard components to adapt to the cylindrical surface, greatly reducing the complexity of manufacturing and installation. Meanwhile, the fastener 110 can be installed at different heights on the cylindrical pier, thereby adjusting the height at which the mounting frame 100 is installed on the cylindrical pier, providing adaptability and operational convenience for high-altitude operations such as construction, inspection, and maintenance.

[0035] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the mounting frame 100 has a U-shaped structure and includes a first connecting part 120, a second connecting part 130, and a third connecting part 140. The first connecting part 120 and the third connecting part 140 are respectively spaced apart on both sides of the second connecting part 130, and are parallel to each other. The fixing member 110 is an angle steel member, and the fixing member 110 has fixing holes spaced apart along its length. The first connecting part 120 has multiple through holes on the side facing away from the platform assembly 200. The fixing member 110 is connected to the first connecting part 120, and fasteners pass through the fixing holes and through holes to achieve a fixed connection between the fixing member 110 and the first connecting part 120. The structure is simple and easy to assemble. The length of the second connecting part 130 is greater than the width of the platform assembly 200. The platform assembly 200 is connected to the second connecting part 130, and the protective member 300 is connected to the third connecting part 140. The protective member 300 is located on the outer perimeter and can provide all-round protection for the safety of the workers and prevent accidental falls.

[0036] In some embodiments of this utility model, such as Figure 1 and Figure 3As shown, the third connecting part 140 has multiple connecting holes 141 spaced apart along its length. There are multiple protective components 300, each corresponding to one of the connecting holes 141. The protective components 300 pass through the connecting holes 141, making the connection simple and convenient, allowing construction personnel to quickly install the protective components 300. The uniform distribution of the protective components 300 along the circumference provides balanced protective force from all angles, ensuring the safety of workers and preventing accidental falls. It should be noted that the protective components 300 are round steel bars, which possess high strength and high toughness, effectively resisting external impacts and are not prone to deformation or breakage due to prolonged use.

[0037] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the second connecting part 130 is horizontally positioned, and the height of the first connecting part 120 is A, where 1m ≤ A ≤ 1.2m. This height range of 1m to 1.2m ensures a stable connection between the fixing component 110 and the cylindrical pier while also providing reasonable space for workers to operate on the platform. The height of the third connecting part 140 is B, where 1.2m ≤ B ≤ 1.5m. That is, the height of the third connecting part 140 is higher than that of the first connecting part 120. Since the third connecting part 140 is located on the periphery of the work platform, its higher height effectively prevents the risk of personnel falling due to accidental imbalance.

[0038] Understandably, the mounting frame 100 optimizes the mechanical performance of the work platform. When the platform is subjected to lateral forces, such as wind, the staggered first connecting part 120, the third connecting part 140, and the horizontal second connecting part 130 together form a triangular structure. The lower first connecting part 120 directly transmits some of the force to the cylindrical pier, while the higher third connecting part 140 can convert the lateral force into downward pressure, which is then distributed to the cylindrical pier through the mounting frame 100 and the fasteners 110. This reduces the lateral deformation of the platform structure, ensuring the entire work platform remains stable under complex external forces and extending its service life.

[0039] In some embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the first connecting part 120, the second connecting part 130, and the third connecting part 140 can be angle steel, channel steel, and H-beam steel. Preferably, in this invention, the first connecting part 120, the second connecting part 130, and the third connecting part 140 are all angle steel, and the L-shaped cross-section of the angle steel has good bending and torsional resistance. This effectively resists bending deformation caused by installation stress and external loads, ensuring the stability of the connection between the mounting frame 100 and the cylindrical pier.

[0040] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the platform component 200 includes a first support component 210 and a second support component 220, which are detachably connected. In some application scenarios, construction workers can prefabricate individual support components and then transport them to the site for assembly, reducing transportation difficulty and cost. The first support component 210 and the second support component 220 are arranged opposite each other, and together they form a polygonal structure. The polygonal structure has stability; compared to circular or irregular shapes, the rigid frame of the polygon can form stable force-bearing points at each corner, evenly distributing the external forces borne by the platform component 200 to the mounting frame 100 and the cylindrical pier through the edges and corners of the polygon.

[0041] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the first support component 210 includes multiple panels 230, each panel 230 being a right-angled trapezoidal plate. Adjacent panels 230 are fixedly connected. It should be noted that adjacent panels 230 are fixedly connected by connectors 240, which are angle steel pieces. Two right-angled trapezoidal plates are joined together along one side of their straight edges to form a trapezoidal structure, and the two trapezoidal plates are then fixedly connected to each other. It can be understood that during the manufacturing process of the panels 230, a rectangular plate can be cut at an angle from the middle to form two right-angled trapezoidal plates. The right-angled trapezoidal panels 230 reduce material waste and lower production costs.

[0042] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the second connecting part 130 is connected to the bottom of the panel 230 and is located at the right-angle connection of two adjacent panels 230. The second connecting part 130 can firmly connect multiple panels 230 together to form a stable whole, which can better resist the loosening of parts caused by vibration, collision and other factors, and ensure the stability of the structure of the work platform during long-term use.

[0043] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, panel 230 is a patterned steel plate. The patterned steel plate has an embossed surface, which enhances the anti-slip effect, effectively preventing personnel from slipping and reducing the risk of accidents caused by falls. At the same time, the patterned steel plate provides stable grip, ensuring safe and efficient operation.

[0044] In some embodiments of this utility model, such as Figure 4As shown, when installing platform component 200, construction workers need to use tools such as wrenches and welding equipment to connect the components. Too close a distance will limit the tool's operating range, leading to reduced installation efficiency or even preventing precise fixing. Therefore, the shortest distance between platform component 200 and the cylindrical pier is D, where 10cm ≤ D. A certain spacing allows platform component 200 and the cylindrical pier to be relatively independent, and the load can be orderly transferred to the cylindrical pier through the installation frame 100, fasteners 110, and other structures, preventing localized compression of the cylindrical pier by platform component 200 under load, thus affecting structural stability.

[0045] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, a first fastening pipe 250 is fixedly connected to the side of the platform assembly 200 facing the cylindrical pier, and a second fastening pipe 260 is fixedly connected to the side of the platform assembly 200 away from the cylindrical pier. Both the first fastening pipe 250 and the second fastening pipe 260 are square tubes. There are multiple first fastening pipes 250, and inclined surfaces are provided on both sides of the first fastening pipe 250. The inclined surfaces facilitate the splicing of multiple first fastening pipes 250. The structure of the second fastening pipe 260 is similar to that of the first fastening pipe 250, and will not be described in detail here. The first fastening pipe 250 and the second fastening pipe 260 are fixedly connected to the platform assembly 200 by welding. The first fastening pipe 250 and the second fastening pipe 260 are used to reinforce the platform assembly 200, thereby enhancing the reliability and practicality of the platform assembly 200.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
