Description

Technical Field

[0001] This utility model relates to the field of steel structure processing and manufacturing technology, specifically to a modular steel structure bending repair and reinforcement device. Background Technology

[0002] A steel structure bending repair and reinforcement device is a specialized piece of equipment used to correct and strengthen steel structural members that have bent due to load, deformation, or damage. It typically includes a hydraulic lifting mechanism, clamps, support frames, high-strength reinforcement materials, and monitoring instruments. Its working principle involves precisely correcting deformed areas through mechanical force, and then reinforcing the structure using methods such as welding, bolting, or bonding composite materials to restore load-bearing capacity and improve durability. Real-time monitoring ensures the safety and accuracy of the repair process. It is widely used in the maintenance and reinforcement of steel structures in buildings, bridges, and other applications.

[0003] In existing technologies, steel structure bending repair mainly relies on customized fixtures. However, due to the significant differences in the size, shape, and degree of bending of steel structure components, the fixtures have poor versatility, requiring redesign and manufacturing for each repair, resulting in high costs and long cycles. Furthermore, the fixture adjustment process is cumbersome and time-consuming, making it difficult to quickly adapt to different deformation conditions and prone to introducing human error, thus compromising repair accuracy. The complex operating procedures further reduce repair efficiency and may even cause secondary damage to components due to sudden pressure changes. Utility Model Content

[0004] In view of this, the present invention provides a modular steel structure bending repair and reinforcement device to solve the problems of limited applicability and complex operation of existing steel structure bending repair devices.

[0005] This utility model provides a modular steel structure bending repair and reinforcement device, including:

[0006] The rod is positioned along the first direction;

[0007] A clamping assembly is disposed on the rod body. The clamping assembly includes a first clamping member, a second clamping member, and an adjusting part. The clamping assembly is slidably connected to the rod body through the adjusting part. The first clamping member and the second clamping member are adapted to slide in a second direction.

[0008] The fixing component allows the first clamping component and the second clamping component to slide relative to each other to a preset position, thereby fixing the first clamping component and the second clamping component.

[0009] Beneficial Effects: The modular steel structure bending repair and reinforcement device provided by this utility model achieves rapid positioning and precise repair of bent steel components through clamping components. The first and second clamping components can slide bidirectionally along the second direction under the drive of the adjustment unit. Combined with the adjustment of the rod in the first direction, this forms an adjustable clamping system that can adapt to steel structures with different cross-sectional dimensions and bending curvatures. The modular assembly structure allows for single-person operation, enabling the clamping components to be locked using fasteners. This improves construction efficiency compared to traditional welding repair and avoids material performance degradation caused by welding overheating.

[0010] In one optional embodiment, the first clamping member includes a first mounting portion and a first clamping portion, wherein the first clamping portion is disposed at the end of the first clamping member away from the rod body, and the first mounting portion is disposed at the sliding engagement point between the first clamping member and the second clamping member.

[0011] Beneficial effects: This utility model improves the applicability and ease of operation of the device by dividing the first clamping member into a first mounting part and a first clamping part. The first clamping part is located at the end away from the rod body, and special clamping modules can be flexibly replaced for steel structures of different shapes to achieve precise force application; the first mounting part is located at the sliding fit and adopts a guide rail structure to avoid the off-center load problem common in traditional clamps.

[0012] In one optional embodiment, the second clamping member includes: a second mounting portion and a second clamping portion, the second clamping portion being disposed at the end of the second clamping member away from the rod body, the distance between the second clamping portion and the rod body being greater than the distance between the first clamping portion and the rod body, the first clamping portion and the second clamping portion being adapted to cooperate in clamping the steel structure, the second mounting portion being disposed at the sliding engagement point between the first clamping member and the second clamping member, the second mounting portion being adapted to cooperate with the first mounting portion to fix the first clamping member and the second clamping member.

[0013] Beneficial Effects: This invention, by making the distance between the second clamping part and the rod greater than the distance between the first clamping part and the rod, can adapt to the repair needs of steel structures of different thicknesses and shapes, effectively expanding the applicability of the device. The second mounting part is precisely matched with the first mounting part and fixed by locking bolts, ensuring smooth sliding adjustment while improving clamping stability compared to traditional structures. This allows the device to achieve large stroke adjustment even in confined spaces, making it particularly suitable for steel structure repair work in restricted spaces.

[0014] In one alternative embodiment, the fastener is adapted to simultaneously pass through the first mounting portion and the second mounting portion.

[0015] Beneficial effects: This utility model achieves linkage locking of the clamping components by having the fixing member pass through the first mounting part and the second mounting part simultaneously. Only one tightening is needed to simultaneously complete the rigid fixing of the clamping members on both sides. The operation time is shortened compared with the traditional split locking method, thus improving construction efficiency.

[0016] In one optional embodiment, the first clamping member and the second clamping member are L-shaped structures. The long sides of the L-shape of the first clamping member and the second clamping member are suitable for sliding fit. The surfaces of the first clamping member and the second clamping member are respectively provided with a first mounting part and a second mounting part. The short sides of the L-shape of the first clamping member and the second clamping member are the first clamping part and the second clamping part.

[0017] Beneficial effects: This utility model adopts an L-shaped first clamping member and a second clamping member. The sliding fit design of the long side of the L-shape forms a guide structure, and the clamping part formed by the short side is integrally formed with the long side. The L-shaped configuration allows the device to achieve angle adjustment in a narrow space, which can meet the repair needs of complex parts such as steel structure beam and column joints.

[0018] In one alternative embodiment, an anti-slip structure is provided on the clamping side of the first clamping part and the second clamping part.

[0019] Beneficial effects: The anti-slip structure ensures the clamping stability of the first clamping part and the second clamping part, and increases the clamping force of the first clamping part and the second clamping part by increasing the friction coefficient of the contact surface.

[0020] In one alternative embodiment, the adjusting part is an adjusting sleeve, and the adjusting part and the rod body are adapted to adjust the position of the clamping assembly along the first direction.

[0021] Beneficial effects: This utility model achieves linear positioning and rapid adjustment of the clamping assembly on the rod by using an adjusting sleeve as the adjusting component. The adjusting sleeve employs a precise fit between its internal thread and the external thread of the rod, and through the self-locking characteristic of the thread, the operation can be completed by a single person.

[0022] In one optional embodiment, the first mounting part and the second mounting part are mounting holes, and the first mounting part and the second mounting part are aligned along the first direction and then connected and fixed by a fastener.

[0023] Beneficial effects: This utility model achieves precise fixation of the clamping assembly by designing the first and second mounting parts as coaxially aligned mounting hole structures. The use of stepped positioning holes in conjunction with pins enables rapid alignment while maintaining stability of the clamping assembly under dynamic loads. It solves the problems of low efficiency and non-reusability of traditional welding fixing methods.

[0024] In one alternative embodiment, the fastener is a pin, suitable for passing through the first mounting portion and the second mounting portion.

[0025] Beneficial effects: This utility model achieves rapid assembly and disassembly of the clamping components and rigid connection by using a pin as a fixing element. Operational efficiency is improved compared to traditional bolt connections.

[0026] In one alternative implementation, multiple modular steel structure bending repair and reinforcement devices are provided, which work together on the steel structure.

[0027] Beneficial effects: This utility model adopts multiple modular steel structure bending repair and reinforcement devices, which can be flexibly arranged according to the deformation characteristics of the steel structure to form a distributed force system, thereby realizing efficient overall repair and reinforcement of large-span steel structures.

[0037] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] A steel structure bending repair and reinforcement device is a specialized piece of equipment used to correct and strengthen steel structural members that have bent due to load, deformation, or damage. This device typically consists of a hydraulic lifting mechanism, clamps, support frames, high-strength reinforcement materials such as carbon fiber cloth or steel plates, and real-time monitoring instruments such as strain gauges and laser rangefinders. Its working principle involves precisely adjusting the deformed areas through mechanical force, combined with techniques such as welding, bolting, or bonding composite materials to reinforce the structure, thereby restoring the load-bearing capacity of the member and improving its durability. Throughout the repair process, the monitoring instruments provide real-time data feedback to ensure correction accuracy and operational safety. These devices are widely used in the repair and reinforcement of steel structures in buildings, bridges, and industrial plants, playing a particularly important role in scenarios requiring rapid restoration of structural function or improvement of seismic performance.

[0039] In existing technologies, steel structure bending repair mainly relies on customized fixtures, but this method has significant drawbacks. Due to the significant differences in the size, cross-sectional shape (e.g., H-beams, box-beams, I-beams), and degree of bending of steel structural components, traditional fixtures have poor versatility, often requiring individual design and manufacturing for each repair task, resulting in high costs and extended lead times. Furthermore, the fixture adjustment process relies on manual operation, which is not only cumbersome and time-consuming but also difficult to quickly adapt to different deformation conditions, easily introducing human error and affecting repair accuracy. The complex operating procedures further reduce overall efficiency, and even during the application of force, uneven or abrupt pressure distribution may cause secondary damage to the components, such as weld cracking.

[0040] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0041] According to an embodiment of the present invention, a modular steel structure bending repair and reinforcement device is provided, comprising: a rod body 1, arranged along a first direction; a clamping assembly 2, disposed on the rod body 1, the clamping assembly 2 including a first clamping member 21, a second clamping member 22 and an adjusting part 23, the clamping assembly 2 being slidably connected to the rod body 1 through the adjusting part 23, the first clamping member 21 and the second clamping member 22 being adapted to slide in cooperation along a second direction; and a fixing member 3, the first clamping member 21 and the second clamping member 22 being slidably moved relative to each other to a preset position, the fixing member 3 fixing the first clamping member 21 and the second clamping member 22.

[0042] The modular steel structure bending repair and reinforcement device provided by this utility model consists of a first clamping member 21 and a second clamping member 22 forming a clamping assembly 2. Under the hydraulic or screw drive of the adjustment part 23, it can achieve bidirectional synchronous sliding in the second direction. At the same time, it cooperates with the extension and retraction adjustment of the rod 1 in the first direction to form a three-dimensional adjustable flexible clamping system, which can adapt to different cross-sectional dimensions such as H-beams and I-beams, and can also adapt to bending deformation.

[0043] In some embodiments, combined with Figure 1 As shown, the first clamping member 21 includes a first mounting part 211 and a first clamping part 212. The first clamping part 212 is disposed at the end of the first clamping member 21 away from the rod body 1, and the first mounting part 211 is disposed at the sliding engagement point between the first clamping member 21 and the second clamping member 22.

[0044] This invention improves the applicability and ease of operation of the device by dividing the first clamping member 21 into a first mounting part 211 and a first clamping part 212. The first clamping part 212 is located at the end away from the rod body 1, and can flexibly replace the special clamping module for steel structures of different shapes to achieve precise force application; the first mounting part 211 is located at the sliding fit and adopts a guide rail structure to avoid the off-center load problem common in traditional clamps.

[0045] In some embodiments, combined with Figure 2 As shown, the second clamping member 22 includes a second mounting portion 221 and a second clamping portion 222. The second clamping portion 222 is disposed at the end of the second clamping member 22 away from the rod body 1. The distance between the second clamping portion 222 and the rod body 1 is greater than the distance between the first clamping portion 212 and the rod body 1. The first clamping portion 212 and the second clamping portion 222 are adapted to cooperate in clamping the steel structure. The second mounting portion 221 is disposed at the sliding engagement point between the first clamping member 21 and the second clamping member 22. The second mounting portion 221 is adapted to cooperate with the first mounting portion 211 to fix the first clamping member 21 and the second clamping member 22. By making the distance between the second clamping portion 222 and the rod body 1 greater than the distance between the first clamping portion 212 and the rod body 1, this utility model can adapt to the repair needs of steel structures of different thicknesses and shapes, effectively expanding the applicability of the device. The second mounting portion 221 and the first mounting portion 211 are precisely matched and fixed by locking bolts, which ensures smooth sliding adjustment while improving clamping stability compared to traditional structures. This device enables large-stroke adjustment even in confined spaces, making it particularly suitable for steel structure repair work in restricted spaces.

[0046] Specifically, the first clamping member 21 and the second clamping member 22 have an L-shaped structure. The long sides of the L-shape of the first clamping member 21 and the second clamping member 22 are suitable for sliding engagement, and their surfaces are respectively provided with a first mounting part 211 and a second mounting part 221. The short sides of the L-shape of the first clamping member 21 and the second clamping member 22 are the first clamping part 212 and the second clamping part 222. This utility model adopts an L-shaped structure for the first clamping member 21 and the second clamping member 22. The sliding engagement design of the long side of the L-shape forms a guiding structure, and the clamping part formed by the short side is integrally formed with the long side. The L-shaped configuration allows the device to achieve angle adjustment in a narrow space, which can meet the repair needs of complex parts such as steel structure beam and column joints.

[0047] Furthermore, an anti-slip structure is provided on the clamping side of the first clamping part 212 and the second clamping part 222. The anti-slip structure ensures the clamping stability of the first clamping part 212 and the second clamping part 222, and improves the clamping force of the first clamping part 212 and the second clamping part 222 by increasing the friction coefficient of the contact surface. Specifically, the anti-slip structure can be an anti-slip pad.

[0048] In some embodiments, combined with Figure 2 As shown, the fixing member 3 is suitable for simultaneously passing through the first mounting part 211 and the second mounting part 221. By having the fixing member 3 simultaneously pass through the first mounting part 211 and the second mounting part 221, this utility model achieves the linkage locking of the clamping assembly 2. Only a single tightening is needed to simultaneously complete the rigid fixing of the clamping members on both sides, shortening the operation time compared to the traditional split locking method and improving construction efficiency.

[0049] Furthermore, the first mounting portion 211 and the second mounting portion 221 are mounting holes. After the first mounting portion 211 and the second mounting portion 221 are aligned along the first direction, they are connected and fixed by the fastener 3. This utility model achieves precise fixing of the clamping assembly 2 by designing the first mounting portion 211 and the second mounting portion 221 as coaxially aligned mounting holes. The use of stepped positioning holes in conjunction with pins enables rapid alignment while ensuring the clamping assembly 2 remains stable under dynamic loads. This solves the problems of low efficiency and non-reusability of traditional welding fixing methods.

[0050] Furthermore, the fixing element 3 is a pin, suitable for passing through the first mounting part 211 and the second mounting part 221. This invention achieves rapid assembly and disassembly of the clamping assembly 2 and rigid connection by using a pin as the fixing element 3. Operational efficiency is improved compared to traditional bolt connections.

[0051] In some embodiments, combined with Figure 1 As shown, the adjusting part 23 is an adjusting sleeve, and the adjusting part 23 and the rod body 1 are adapted to adjust the position of the clamping assembly 2 along the first direction. This invention achieves linear positioning and rapid adjustment of the clamping assembly 2 on the rod body 1 by using an adjusting sleeve as the adjusting part 23. The adjusting sleeve uses a precise fit between its internal thread and the external thread of the rod body 1, and through the self-locking characteristic of the thread, the operation can be completed by a single person.

[0052] In some embodiments, combined with Figure 1 As shown, multiple modular steel structure bending repair and reinforcement devices are configured to work together on the steel structure. This invention, by employing multiple modular steel structure bending repair and reinforcement devices, can be flexibly arranged according to the deformation characteristics of the steel structure to form a distributed force-bearing system, achieving efficient overall repair and reinforcement of large-span steel structures.

[0053] The first clamping member 21 and the second clamping member 22 of this utility model are two claw discs. They are connected and slidably connected by a sliding structure to clamp H-beams and box beams with different flange widths (100-500mm). The bodies of the first clamping member 21 and the second clamping member 22 are provided with positioning holes corresponding to different clamping positions to facilitate quick alignment by the operator. After alignment, a pin is inserted into the positioning hole for clamping and fixing. The clamping ends are equipped with serrated anti-slip textures to increase friction. Rubber pads can also be replaced to protect the workpiece surface. The adjusting part 23 is a telescopic sleeve. The rod body 1 and the adjusting part 23 form a spiral lifting mechanism, which can be manually extended and retracted vertically with a stroke range of 200-1200mm. The gap between the claws is adjusted through the sliding track to cover different flange widths (100-500mm). The telescopic sleeve structure is used to adapt to different web heights (200-1200mm). Meanwhile, the claw plate connects to one end of the telescopic bracket module, which is designed as a circular insertion structure. It is inserted into the telescopic sleeve for connection, forming a modular interface that allows for quick installation and disassembly.

[0054] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
