Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and more specifically, to a detachable guy rope clamping device for ultra-long steel columns. Background Technology

[0002] In projects such as super high-rise buildings and long-span steel structures, the hoisting and temporary fixing of ultra-long steel columns (typically exceeding 30 meters in height) is a critical construction step. Due to the high slenderness ratio and limited rigidity of steel columns, they are highly susceptible to external factors such as wind loads, hoisting eccentricity, and construction vibrations before a stable structure is formed after hoisting, which can lead to overturning, deflection, or deviations in verticality. If temporary fixing measures fail, it may cause steel column collapse, threatening construction safety and delaying the project schedule.

[0003] Currently, temporary fixing methods using guy ropes to connect steel columns are commonly used in engineering projects. However, these fixing points often rely on welding: one method involves welding temporary lugs to the surface of the steel column, while another involves welding limiting baffles to the edge of the top plate of the steel column. However, welding fixation has significant drawbacks: the high temperatures of welding can damage the metallographic structure of the steel column base material, creating localized stress concentrations that could compromise the structural performance and durability of high-strength steel or anti-corrosion coated steel columns; dismantling requires cutting and repair, reducing construction efficiency and posing a risk of secondary damage. Furthermore, welding positions must avoid key areas such as main welds and stiffening ribs, limiting the placement of guy ropes and making it difficult to meet multi-angle stress requirements.

[0004] With the continuous development of super high-rise buildings and long-span steel structures, higher requirements are placed on the hoisting accuracy and construction efficiency of ultra-long steel columns. Existing fixing methods, due to the aforementioned problems, are no longer sufficient to meet the needs of modern steel structure construction. Therefore, it is necessary to propose a detachable guy rope clamping device for ultra-long steel columns to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a detachable guy rope clamping device for ultra-long steel columns. It aims to improve the existing methods of temporarily fixing steel columns, which often rely on temporarily welding ear plates or limiting baffles to the surface of the steel column and then using guy ropes for fixation. The high temperature of welding can damage the metallographic structure of the steel column base material, forming local stress concentration, which poses a hidden danger to the structural performance and durability of high-strength steel or anti-corrosion coated steel columns. Furthermore, dismantling requires cutting and repair, which reduces construction efficiency and poses a risk of secondary damage.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a detachable guy rope clamping device for ultra-long steel columns, including a steel column component and a clamping device.

[0008] The steel column component includes an H-shaped steel column and a column top plate, with the column top plate fixed to the end of the H-shaped steel column. The clamping device includes a first clamping plate, a second clamping plate, and a connecting part. Each of the first and second clamping plates has a clamping groove on one side, which engages with both sides of the column top plate. The connecting part is fixed to the first and second clamping plates, and a locking element is installed on the connecting part. An ear plate is fixed to one side of the first and second clamping plates, and a rope hole passes through the inside of the ear plate.

[0009] In one embodiment of this utility model, both sides of the first clamping plate and the second clamping plate are fixed with reinforcing plates. The reinforcing plates are located on one side of the clamping groove, and one side of the reinforcing plates is in close contact with the surface of the column top plate.

[0010] In one embodiment of the present invention, the connecting part includes two connecting plates, which are respectively fixed to the first clamping plate and the second clamping plate. A reinforcing plate is fixed between the two connecting plates and the first clamping plate and the second clamping plate, and nail holes are correspondingly opened inside the two connecting plates.

[0011] In one embodiment of this utility model, the locking member includes a bolt and a nut, the bolt passing through the nail hole and the nut being threadedly connected to the end of the bolt.

[0012] In one embodiment of this utility model, the ear plate is tilted outward to one side and tilted downward in the horizontal direction.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a detachable guy rope clamping device for ultra-long steel columns, designed as described above. In use, two clamping devices work together and are installed at both ends of the column top plate. First, the clamping grooves on the first and second clamping plates are engaged with the sides of the column top plate and aligned using the nail holes on the connecting plate. Then, bolts are passed through the nail holes and tightened using nuts. After tightening, the reinforcing plate is tightly fitted to the side of the column top plate. The reinforcing plate increases the local rigidity of the contact area between the first and second clamping plates and the column top plate, enhancing the load-bearing capacity of key parts. One end of the guy rope is installed in the rope hole of the ear plate, and the other end is reliably anchored to the ground anchor, concrete foundation, or structural member for fixation. The inclined ear plate design optimizes the transmission path of the guy rope tension, allowing the tension to be applied evenly to the cross-section of the ultra-long steel column, reducing the risk of steel column damage caused by local stress concentration. Thus, after the steel column is hoisted into place but before it is formally fixed, the guy rope can provide temporary support to prevent the steel column from tilting, falling, or swaying due to its own weight, wind force, or construction load. This avoids damage to the surface coating and structural performance of the steel column caused by on-site welding during use. The symmetrical arrangement of the device on both sides forms a bidirectional force balance structure, which can counteract the offset moment generated by the guy rope tension, ensuring the overall stability of the ultra-long steel column during installation, which is conducive to improving construction efficiency and reducing potential hazards.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example

[0021] Please see Figures 1-3 This utility model provides a technical solution: a detachable guy rope clamping device for ultra-long steel columns, including a steel column component 100 and a clamping device 200.

[0022] Please see Figure 1 The steel column component 100 includes an H-shaped steel column 110 and a column top plate 120, with the column top plate 120 fixed to the end of the H-shaped steel column 110.

[0023] Please see Figures 1-3 The clamping device 200 includes a first clamping plate 210, a second clamping plate 220, and a connecting part 240. Each of the first clamping plate 210 and the second clamping plate 220 has a clamping groove 221 on one side. The clamping groove 221 is engaged with both sides of the column top plate 120. A high-strength wear-resistant rubber protective layer can be provided inside the clamping groove 221 to increase friction and make the engagement more stable and prevent slippage. The connecting part 240 is fixed on the first clamping plate 210 and the second clamping plate 220. A locking member 250 is installed on the connecting part 240. An ear plate 260 is fixed on one side of the first clamping plate 210 and the second clamping plate 220. A rope hole 261 passes through the inside of the ear plate 260.

[0024] Both sides of the first clamping plate 210 and the second clamping plate 220 are fixed with reinforcing plates 230. The reinforcing plates 230 are located on one side of the clamping groove 221, and one side of the reinforcing plates 230 is in close contact with the surface of the column top plate 120. Here, the reinforcing plates 230 are triangular and are in close contact with the surface of the column top plate 120. This can enhance the overall rigidity of the first clamping plate 210 and the second clamping plate 220, effectively resist the deformation caused by external loads, and ensure the structural integrity of the clamping device 200 under complex stress conditions.

[0025] The connecting part 240 includes two connecting plates 241, which are fixed to the first clamping plate 210 and the second clamping plate 220 respectively. A reinforcing plate 242 is fixed between the two connecting plates 241 and the first clamping plate 210 and the second clamping plate 220 respectively. The interiors of the two connecting plates 241 have corresponding nail holes 243. The locking component 250 includes a bolt 251 and a nut 252. The bolt 251 passes through the nail hole 243, and the nut 252 is threaded onto the end of the bolt 251. Here, the two connecting plates 241 are fitted together to align the corresponding nail holes 243, and then the bolt 251 passes through the nail hole 243 and is locked by the nut 252. This facilitates the clamping and fixing of extra-long steel columns and the installation of guy ropes. This design abandons the traditional welding connection method, enabling rapid installation and disassembly of the device, avoiding damage to the steel column surface, and improving construction efficiency.

[0026] The ear plate 260 is inclined outward to one side and downward in the horizontal direction. This angle is optimized through mechanical analysis to suit the expected tension direction of the guy rope, effectively adapting to multi-angle tension loads under different working conditions. The ear plate 260 has rope holes 261 inside and is equipped with wear-resistant bushings. As the connecting carrier for the guy rope, when the guy rope is under tension, the tension is transmitted through the ear plate 260 to the clamping device 200, and then to the H-shaped steel column 110, achieving stable support for the ultra-long steel column. Through symmetrical arrangement and angle optimization, the ear plate 260 can evenly bear multi-directional tension, improving the stress rationality and stability of the entire device.

[0027] Specifically, the structural principle of the detachable guy rope clamping device for ultra-long steel columns is as follows: In use, two clamping devices 200 are used together and installed at both ends of the column top plate 120. First, the clamping grooves 221 on the first clamping plate 210 and the second clamping plate 220 are engaged with the sides of the column top plate 120 and aligned with the nail holes 243 on the connecting plate 241. Then, bolts 251 are passed through the nail holes 243 and tightened using nuts 252. After tightening, the reinforcing rib 230 is tightly attached to the side of the column top plate 120. The reinforcing rib 230 increases the local rigidity of the contact area between the first clamping plate 210 and the second clamping plate 220 and the column top plate 120, thus enhancing the strength of the clamping device. The load-bearing capacity of key components is assessed. One end of the guy rope is installed in the rope hole 261 of the ear plate 260, and the other end is reliably anchored to the ground anchor, concrete foundation, or structural member for fixation. The design of the inclined ear plate 260 optimizes the transmission path of the guy rope tension, allowing the tension to be evenly applied to the cross-section of the ultra-long steel column, reducing the risk of steel column damage due to local stress concentration. Thus, after the steel column is hoisted into place but before it is formally fixed, the guy rope can provide temporary support to prevent the steel column from tilting, falling, or swaying due to its own weight, wind force, or construction load. This avoids damage to the surface coating and structural performance of the steel column caused by on-site welding during use. The symmetrically arranged devices on both sides form a bidirectional force balance structure, which can counteract the offset moment generated by the guy rope tension, ensuring the overall stability of the ultra-long steel column during installation, which is conducive to improving construction efficiency and reducing potential hazards.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
