In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0035] Ordinary reinforced concrete structures are prone to cracking in the tension zone when subjected to loads such as self-weight, live loads, and seismic forces due to the low tensile strength of the concrete. Tensile prestressing steel bars or strands induce prestress in the concrete. When the structure is subjected to external loads, this prestress counteracts the tensile stress generated by the load, keeping the actual tensile stress in the concrete tension zone within acceptable limits. This effectively avoids or reduces cracking, and is particularly suitable for structures with high requirements for waterproofing and durability, such as bridges, water tanks, and roof beams. In related technologies, tensioning platforms are specialized equipment or operating platforms designed specifically for prestressing tensioning operations in engineering construction. However, tensioning platforms have complex structures, are inconvenient to assemble and disassemble, and suffer from insufficient overall structural stability, affecting construction safety, project quality, and operational efficiency.

[0036] Therefore, such as Figures 1 to 8As shown, the tensioning platform proposed in this utility model includes: an operating platform 100 and column assemblies 200. The operating platform 100 includes a support frame 110 and a footboard 120. The support frame 110 has a rectangular structure and is located at the bottom of the footboard 120. The support frame 110 and the footboard 120 form an integral force-bearing platform, and the footboard 120 directly supports the tensioning equipment and operators. A protective element 130 is connected to the periphery of the support frame 110 to provide protection when personnel approach the edge, avoiding the risk of falling. Multiple column assemblies 200 are arranged at intervals along the outer periphery of the operating platform 100. A first limiting element 210 is provided on the side of each column assembly 200 away from the support frame 110. The first limiting element 210 restricts the movement of the tensioning equipment, preventing the equipment from sliding or tipping under the tensioning reaction force, further reducing safety risks during operation and comprehensively ensuring the safety of construction personnel and equipment. The support frame 110, protective component 130 and column together form a stable structure. The overall structure is simple and easy to assemble. It can stably withstand tensioning operations and avoid problems such as shaking and tilting during tensioning, providing a solid and reliable operating platform for tensioning operations.

[0037] Furthermore, the bottom support frame 110 needs to withstand the overall load of the platform and the tension reaction force. Fatigue cracks are prone to occur at right-angle corners due to stress concentration, especially under vibration loads from repeated tensioning. Therefore, in some embodiments of this utility model, referring to… Figure 3 The corners of the support frame 110 are chamfered, which allows stress to transition smoothly along the corners, reduces local stress, and extends the service life of the frame.

[0038] Specifically, in some embodiments of this utility model, reference is made to... Figure 3 and Figure 8 As shown, the support frame 110 is formed by splicing two plates symmetrically. The plates are made of channel steel (#10 channel steel, meaning the cross-sectional height is 100 mm). The symmetrical splicing ensures balanced stress on the two plates, forming a stable overall load-bearing system, effectively distributing external loads and preventing deformation or damage caused by localized stress concentration. Multiple fixing holes are provided at the connection points of the two plates, which are then fixed together using 8.8 grade high-strength bolts. This ensures sufficient tightening force at the connection points of the two channel steel plates, preventing loosening even under long-term stress or vibration conditions, significantly improving the overall rigidity and connection reliability of the support frame 110.

[0039] In some embodiments of this utility model, such as Figures 1 to 8As shown, there are multiple protective components 130, which are disposed between two adjacent column assemblies 200. Each protective component 130 has a plate-like structure, with its bottom fixedly connected to the support frame 110 and its two sides fixedly connected to the two column assemblies 200 respectively. Multiple first connecting portions 131 are spaced longitudinally on each protective component 130, each with a first through hole. Multiple second connecting portions 250 are provided on each column assembly 200, each with a second through hole. The first connecting portions 131 and second connecting portions 250 correspond one-to-one and are fixedly connected. The column assemblies 200 and protective components 130 are fixed together by fasteners located at the first and second through holes, forming a continuous protective barrier that prevents people from falling and improves the overall frame rigidity.

[0040] In some embodiments of this utility model, such as Figure 4 and Figure 8 As shown, the bottom of the protective component 130 is provided with a connecting groove 132, which extends along the length of the protective component 130. One side wall of the connecting groove 132 is provided with multiple connecting holes 133, which are spaced apart along the length of the protective component 130. The connecting holes 133 cooperate with fasteners to fix the protective component 130 to the support frame 110. It can be understood that the fixing of the protective component 130 to the column assembly 200 and the fixing of the protective component 130 to the support frame 110 can also be achieved by using 8.8 grade high-strength bolts to ensure the reliability of the connection and improve the overall rigidity.

[0041] In some embodiments of this utility model, such as Figure 5 and Figure 7 As shown, the column assembly 200 includes two connectors 220. Each connector 220 has an opening on one side, meaning it is a channel-shaped structure with an opening on one side. Each connector 220 includes flanges on both sides and a web located between the flanges. The two connectors 220 are fixedly connected together by welding or fasteners. The openings of the two connectors 220 are opposite each other and together enclose the column assembly 200. Loads can be transferred through the flanges and web of the two connectors 220, avoiding stress concentration on a single component. In some applications, when the column assembly 200 is subjected to vertical pressure, the force can be evenly distributed to the web of the two connectors 220. When subjected to lateral forces, the shear resistance of the closed section can reduce the deformation of individual channel steel flanges, reduce the stress load on the connection nodes, and extend the service life of the structure.

[0042] In some embodiments of this utility model, such as Figure 5 and Figure 7As shown, connector 220 is made of channel steel. The two channel steels are interlocked to form a closed section, which can more stably bear the load during tensioning operations, reduce the deformation of the support components, and meet the high-strength support requirements of the tensioning operation platform.

[0043] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, there are multiple first limiting members 210, distributed on both sides of the column assembly 200, and spaced apart along the length of the column assembly 200. Each first limiting member 210 has a slot 211, with the slot 211 on one side of the column assembly 200 facing in the opposite direction to that on the other side. The first limiting members 210 on both sides can limit components in different directions, such as connecting components, supporting components, and auxiliary structures of tensioning equipment. Because the slots 211 face in opposite directions, the forces on both sides can form a certain reverse balance, preventing the column assembly 200 from tilting or deforming due to excessive force on one side, thereby improving the overall structure's resistance to overturning and its stability.

[0044] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the outer wall of the first limiting member 210 is provided with a reinforcing plate 230, which includes a first reinforcing plate and a second reinforcing plate, respectively disposed on both sides of the first limiting member 210. The first reinforcing plate has a triangular structure and is disposed on the side of the first limiting member 210 with an opening, and its two sides are fixedly connected to the two side walls of the first limiting member 210. The second reinforcing plate has a rectangular structure and is located at the connection between the first limiting member 210 and the column assembly 200. The first and second reinforcing plates can be fixedly connected to the first limiting member 210 by welding, bonding, or fastener connection, or the first and second reinforcing plates can be integrally formed with the first limiting member 210. The reinforcing plate 230 ensures that the connection between the first limiting member 210 and the column assembly 200 has sufficient fastening force and shear resistance, making the tensioning equipment more stable during the limiting process, indirectly ensuring the alignment accuracy between the tensioning equipment and the prestressing tendon axis, and reducing the risk of eccentric tensioning.

[0045] In some embodiments of this utility model, such as Figure 5 and Figure 7As shown, the thickness of the reinforcing plate 230 is A, where 10mm ≤ A ≤ 20mm. A thickness of 10mm to 20mm provides sufficient fatigue strength, reducing the risk of plate cracking due to repeated stress. At the same time, the moderate thickness facilitates subsequent anti-corrosion treatments, such as painting and galvanizing, extending the service life of the reinforcing plate 230 and ensuring the long-term reliability of the structure.

[0046] In other embodiments of this utility model, such as Figure 5 and Figure 7 As shown, the thickness of the reinforcing plate 230 is 16mm, and the reinforcing plate 230 is made of steel. The steel plate has the characteristics of high strength and high toughness, which can ensure that the reinforcing plate 230 plays an effective reinforcing role when bearing load, resist the impact force during tensioning, avoid deformation of the connection parts, and improve the stability of the tensioning operation.

[0047] In some embodiments of this utility model, such as Figure 1 As shown, the column assembly 200 includes a second limiting member 240, which is fixedly connected to the first limiting member 210 by welding. The second limiting member 240 has an opening on one side, facing away from the column assembly 200. The second limiting member 240, with its slot 211 facing a different direction than that of the first limiting member 210, can limit components in different directions, such as connecting components, support components, and auxiliary structures of tensioning equipment, thereby improving the equipment versatility of the tensioning platform.

[0048] In some embodiments of this utility model, the pedal 120 is a patterned steel plate with a thickness of 3mm. The 3mm thickness of the steel plate can withstand the weight of a person or the load of light equipment, and it is not easily bent or deformed under stress, ensuring the structural stability of the pedal 120 and avoiding the risk of breakage due to excessive thinness. The raised texture on the surface of the patterned steel plate significantly increases the friction between the pedal 120 and the sole of the shoe, especially in wet, oily, or water-filled conditions, effectively reducing the risk of slipping.

[0049] Specifically, in some embodiments of this utility model, the entire platform adopts a modular design, meaning that the support frame 110, pedal 120, protective components 130, and column assembly 200 can all be prefabricated and assembled on-site with bolts, making installation and disassembly convenient and reusable, thus reducing the investment cost of temporary construction facilities. Meanwhile, the column assembly 200 has multiple first limiting components 210, which can adapt to different tensioning equipment usage scenarios, demonstrating strong versatility and meeting the needs of various tensioning operations.

[0050] 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.
