Description

Technical Field

[0001] This invention relates to the field of building engineering, specifically to a corrective connection component for embedded steel structures. Background Technology

[0002] As a core component connecting the steel structure and the concrete base in a building structure, the installation accuracy of steel structure embedded parts directly affects the structural force transmission stability and overall safety. In actual construction, due to factors such as concrete pouring and vibration, formwork positioning deviation, and insecure fixing of embedded parts, embedded parts often experience problems such as small positional offsets, large displacements, or tilting. If the deviation exceeds the allowable range, it will lead to inaccurate alignment of the steel structure installation, or even damage to the force transmission path, causing safety hazards such as uneven structural stress and localized stress concentration.

[0003] Existing embedded part correction technology has obvious limitations: on the one hand, the correction tools are mostly simple jacking devices, which have uneven jacking force output, easily causing secondary deformation of the embedded parts, and lack an elastic compensation mechanism, making them unsuitable for embedded parts of different weights and types; on the other hand, the connecting components have fixed shapes, which can only deal with a single type of deviation. Small deviations require additional welding of supplementary plates, large deviations require re-embedding, and tilting deviations require on-site processing of wedge-shaped pads. This not only makes the construction process cumbersome and prolongs the construction period, but also has problems such as insufficient connection rigidity and unreliable force transmission.

[0004] Furthermore, traditional techniques involve separate steps for correction and connection, requiring multiple sets of tools and components, resulting in high construction costs. Moreover, the precision of on-site component fabrication is difficult to guarantee, further reducing the stability of project quality. Therefore, there is an urgent need for an integrated component that can achieve precise and stable correction, adapt to various deviation types, and integrate correction and connection functions to address the pain points of existing technologies, such as poor adaptability, complex operation, and insufficient reliability. Summary of the Invention

[0011] Preferably, the second hinged steel plate and the first hinged steel plate are folded and welded together, and then laid flat and flush with the surface of the main pad steel plate to form a transition plate connection structure.

[0012] Preferably, the second hinged steel plate is placed at a certain angle to the first hinged steel plate and then at a certain angle to the main pad steel plate to form a wedge-shaped pad connection structure.

[0016] This invention provides a corrective connection component for embedded parts in steel structures. It has the following beneficial effects: 1. This invention provides precise and stable correction, eliminating secondary damage. A hydraulic cylinder provides the basic jacking force, which, combined with spring plate elastic compensation and pressure roller sliding compensation mechanisms, ensures a uniform and constant jacking force, preventing uneven stress and deformation of the embedded parts. The jacking force can be precisely adjusted via an internal hexagonal adjusting nut to suit different types of embedded parts.

The hinged design combined with the waist hole improves the installation tolerance, and welding and bolt fixing, along with rib reinforcement, form a clear force transmission path, ensuring connection rigidity and long-term stability.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] Please see the appendix Figure 1 -Appendix Figure 7 This invention provides a corrective connection component for embedded steel structures, such as... Figure 1As shown, the system includes a correction connection component 1 and a correction auxiliary component 2. These two components work together to achieve precise correction and reliable connection of the embedded parts. The correction auxiliary component 2 is responsible for the stable jacking correction of the misaligned embedded parts, while the correction connection component 1 adaptively adjusts its shape according to the type of deviation after correction to achieve fixation. This eliminates the need for multiple sets of tools, achieving integrated correction-connection operations and significantly simplifying the construction process. The correction connection component 1 includes a main pad steel plate 101. The main pad steel plate 101 serves as the foundational load-bearing component of the correction connection component 1, providing a stable installation reference for various hinged steel plates, ribs, and other components. Its structural strength adapts to different load scenarios, effectively transferring the force between the embedded parts and the concrete base, ensuring the overall stability of the connection structure. One end of the main pad steel plate 101 is movably mounted with a first hinged steel plate 102 via a hinge. The hinge connection gives the first hinged steel plate 102 flexible rotation and adjustment capabilities, allowing adjustment of its relative angle with the main pad steel plate 101 according to the type of deviation of the embedded part (small positional deviation, large positional deviation, tilt deviation). This provides a foundation for subsequent assembly of different connection structures, and the hinge connection is reliable in strength, forming a stable force transmission node after folding and welding. One end of the first hinged steel plate 102 is movably mounted with a second hinged steel plate 103 via a hinge. The second hinged steel plate 103 is connected to the first hinged steel plate 102 via a hinge, further expanding the shape adjustment range of the correction connection component 1. It can achieve various states such as folded fit and angled placement. Its surface structure design is adapted to the welding and fixing of the embedded part, and the rectangular pad plate 108 at the end can provide anti-slip support during tilt deviation correction. The surface of the second hinged steel plate 103 is also provided with a welding groove 107. The welding groove 107 ensures that the contact area between the second hinged steel plate 103 and the embedded part is sufficient when welding. After full welding, a sealed and firm connection node can be formed, avoiding stress concentration at the welded part, improving the shear and pull-out resistance of the connection structure, ensuring effective force transmission, and preventing loosening of the connection during long-term service. The correction auxiliary component 2 includes a channel steel bracket 201. The channel steel bracket 201 is made of steel structure material, which has high strength and good deformation resistance. As the installation base of the correction auxiliary component 2, it can maintain horizontal stability after being fixed to the concrete base with expansion bolts, providing firm support for the hydraulic cylinder 202 and preventing the decrease in jacking accuracy due to bracket displacement during the correction process. The channel steel support 201 is internally fixed with a hydraulic cylinder 202. The hydraulic cylinder 202 serves as the power source for jacking and correction. By driving the internal piston rod to move linearly, it provides a continuous and stable foundation jacking force for the upright 203 and the arc-shaped jacking plate 206. Its thrust output is uniform and can adapt to the correction needs of embedded parts with different weights and different deviations. There is no need to manually apply jacking force, thus reducing the construction intensity.The drive end of the hydraulic cylinder 202 extends to the outside of the channel steel bracket 201 and is fixedly mounted on a vertical frame 203. The vertical frame 203 serves as the core mounting carrier for the correction auxiliary component 2. It has an internal cavity structure adapted to components such as the spring plate 208, support platform 210, and short shaft 212. This ensures the orderly installation of each component and provides a stable working space for the transmission mechanism and elastic compensation mechanism, ensuring the coordinated operation of each component during the jacking correction process. Rotating frames 204 are movably mounted on both the upper and lower ends of the vertical frame 203. The rotating frames 204 can rotate flexibly around the mounting axis of the vertical frame 203. When the arc-shaped jacking plate 206 contacts the embedded part and is subjected to a reaction force, the rotating frame 204 will rotate accordingly, forming pressure on the spring plate 208 through the pressure roller 209. Its rotation angle can be adaptively adjusted according to the magnitude of the jacking force, ensuring that the bending degree of the spring plate 208 matches the jacking force requirement. Connecting plates 205 are movably mounted on the outer ends of the rotating frame 204. These connecting plates 205 serve as the force transmission medium between the rotating frame 204 and the arc-shaped jacking plate 206. Their movable connection design allows for adaptive angle adjustment during the jacking process, ensuring the arc-shaped jacking plate 206 remains in contact with the surface of the embedded part. This prevents localized force concentration due to irregularities in the embedded part's surface and smoothly transmits the rotational force of the rotating frame 204 and the elastic force of the spring plate 208 to the arc-shaped jacking plate 206. One end of the arc-shaped jacking plate 206 is movably mounted on the end of each connecting plate 205. The arc-shaped jacking plate 206's arc-shaped structure increases the contact area with the embedded part, ensuring even distribution of the jacking force across its surface. This effectively prevents secondary deformation of the embedded part caused by excessive localized force. Its movable mounting allows for fine-tuning of its posture during the jacking process, further enhancing the uniformity and stability of the jacking. The upright frame 203 has a first chamber 207 on both sides. The first chamber 207 provides independent installation space for the spring plate 208, the support platform 210, and the threaded rod 213, limiting the movement trajectory of each component and avoiding interference between components. At the same time, it provides sufficient space for the bending deformation of the spring plate 208, ensuring the smooth implementation of the elastic compensation mechanism and ensuring the stable output of the jacking force. The spring plate 208 is fixedly installed on both sides of the first chamber 207, and the ends of the spring plates 208 extend into the interior of the corresponding side rotating frame 204. The spring plate 208 is the core component of elastic compensation and has good elastic recovery performance. After being bent by the pressure roller 209, it can generate a reverse elastic force. This elastic force acts in the opposite direction on the embedded part through the connecting plate 205 and the arc-shaped jacking plate 206, balancing the fluctuation of the jacking force of the hydraulic cylinder 202. The design of the end extending into the interior of the rotating frame 204 ensures that the force transmission is direct and smooth, avoiding elastic force loss.Pressure rollers 209 are fixedly installed on the inner wall of the rotating frame 204, and the inner ends of the pressure rollers 209 abut against one end surface of the corresponding side spring plate 208. The pressure rollers 209 and the surface of the spring plate 208 abut against each other. When the rotating frame 204 rotates, the pressure rollers 209 can slide relative to the surface of the spring plate 208, effectively compensating for the elastic force difference caused by the change in the curvature of the spring plate 208, ensuring that the pushing force applied by the arc-shaped push plate 206 to the embedded part is always uniform and constant, and avoiding uneven force on the embedded part due to elastic force fluctuation.

[0022] In this embodiment, a first waist hole 104 is provided in the middle of the main pad steel plate 101. The first waist hole 104 provides adjustment space for bolt installation, which can compensate for minor positioning errors during the installation process, reduce the accuracy requirements of drilling and bolt insertion, and facilitate the adjustment of the relative position of the main pad steel plate 101 and the chemical bolt or embedded part, ensuring the installation accuracy of the connection structure and adapting to the fixing requirements under different deviation scenarios. A second waist hole 105 is provided in the middle of the first hinge steel plate 102. The second waist hole 105, the first waist hole 104, and the third waist hole 106 form a waist hole combination structure. When forming the transition plate connection structure 4, the connecting parts at the designed position can be accurately aligned through the waist hole combination, providing flexible adjustment space for bolt fixing and ensuring that a smooth force transmission path can be formed even if there is a large deviation in the embedded part. The second hinged steel plate 103 has a third waist hole 106 in the middle. The third waist hole 106, together with the second waist hole 105, realizes the bolt positioning of the transition plate connection structure 4. At the same time, it can also be used as a spare fixing hole in the supplementary plate connection structure 3 and the wedge-shaped pad connection structure 5, thereby improving the installation flexibility and reliability of the connection structure, ensuring the stability of bolt fixing, and strengthening the force transmission effect.

[0023] Furthermore, a rectangular foot plate 108 is movably mounted on one end of the second hinged steel plate 103 via a hinge. The rectangular foot plate 108 is connected to the second hinged steel plate 103 via a hinge and can be flexibly folded for storage or unfolded for use. After unfolding in the wedge-shaped foot plate connection structure 5, it contacts the concrete base layer, increasing the stress-bearing area of ​​the connection structure and effectively preventing slippage under stress, thus ensuring the connection stability after tilt deviation correction. Bolt mounting holes 109 are provided on both sides of the interior of the rectangular foot plate 108. The bolt mounting holes 109 are used to pass bolts through and fix the rectangular foot plate 108 to the concrete base layer, forming a stable support anchor point, improving the anti-slip capability of the connection structure, avoiding positional displacement of the connection structure under long-term load, and ensuring the connection reliability of the tilted embedded parts. The bottom end of the main pad steel plate 101 is provided with a pad plate storage notch 110 on the side near the first hinge steel plate 102. The size of the pad plate storage notch 110 is adapted to the rectangular pad plate 108. When not in use, the rectangular pad plate 108 can be folded and stored in it, reducing the overall space occupied by the correction connection component 1, facilitating transportation, storage and carrying, and preventing damage to the rectangular pad plate 108 during storage.

[0024] Furthermore, first rib rods 111 are movably installed on both sides of the top of the main pad steel plate 101. As core components enhancing connection rigidity, the first rib rods 111 nest with second rib rods 112, allowing for adjustment of their extension length according to the rigidity requirements of the connection structure. Their movable installation ensures effective adaptation to different connection structure configurations, providing additional support for the connection structure. Second rib rods 112 are movably installed on both sides of the top of the first hinged steel plate 102, with the ends of the second rib rods 112 movably positioned inside the corresponding first rib rods 111. The second rib rods 112 nest within the first rib rods 111, forming a retractable rib structure. By adjusting the nesting length and fixing with locking bolts 113, the overall rigidity and deformation resistance of the correction connection component 1 can be significantly enhanced, adapting to different load scenarios. Locking bolts 113 are installed on one side of the middle part of the first rib rod 111. The locking bolts 113 are used to lock the relative position of the first rib rod 111 and the second rib rod 112, so as to ensure the stability of the support stiffness of the rib structure, avoid the relative sliding of the two due to vibration, load and other factors during long-term use, ensure the stiffness enhancement effect of the connection structure, and prevent the deformation of the connection part.

[0025] Furthermore, the second hinged steel plate 103 and the first hinged steel plate 102 are folded and welded together, and placed at a 90° angle with the main pad steel plate 101 to form a supplementary plate connection structure 3. The supplementary plate connection structure 3 is specifically designed for small positional deviations of the embedded parts. The 90° placement can accurately compensate for the installation gap caused by small deviations. It is fully welded to the embedded parts through the welding groove 107 and fastened to the first waist hole 104 with chemical bolts to form a reliable fixing structure, which is reinforced with rib rods to enhance rigidity. Furthermore, the second hinged steel plate 103 and the first hinged steel plate 102 are folded and welded together, and placed flat with the surface of the main pad steel plate 101 to form a transition plate connection structure 4. The transition plate connection structure 4 is adapted to large positional deviations of the embedded parts. After being placed flat, it can form a flat transition force transmission surface. It is aligned by the combination of the first waist hole 104, the second waist hole 105 and the third waist hole 106, and reinforced by welding after bolt fixing, thus constructing a complete and smooth force transmission path to ensure effective force transmission. Furthermore, the second hinged steel plate 103 is placed at a certain angle to the first hinged steel plate 102, and then at a certain angle to the main pad steel plate 101 to form a wedge-shaped pad connection structure 5. The wedge-shaped pad connection structure 5 is designed to address the tilt deviation of the embedded part. By adjusting the angle between the two hinged steel plates, the welding groove 107 is made to fit tightly with the tilted surface of the embedded part. After full welding, it is fixed with the rectangular pad plate 108 to completely eliminate the stress hazards caused by the tilt and ensure the stability of the connection.

[0026] Furthermore, a support platform 210 is movably installed in the center of the first chamber 207, with both sides of the support platform 210 abutting against the other end surface of the corresponding spring plate 208. The support platform 210 serves as the bending fulcrum of the spring plate 208, and its position can be adjusted by the threaded rod 213, thereby changing the bending shape and elastic force of the spring plate 208. The design of both sides abutting against the spring plate 208 ensures that the spring plate 208 is subjected to balanced force, and the elastic compensation effect is symmetrical and stable. Furthermore, a second chamber 211 is opened in the center of the upright frame 203. The second chamber 211 provides independent installation space for transmission components such as the short shaft 212, driven bevel gear 214, and driving bevel gear 217, limiting the position of each transmission component, ensuring precise gear meshing, smooth transmission without interference, and providing a stable transmission environment for adjusting the thrust. Both sides of the second chamber 211 are movably mounted with short shafts 212. One end of the short shaft 212 is connected to the driven bevel gear 214, and the other end is connected to the threaded rod 213. This allows the rotational motion of the driven bevel gear 214 to be precisely transmitted to the threaded rod 213. The movable mounting design ensures flexible rotation without jamming, guaranteeing transmission efficiency and adjustment accuracy. The outer ends of the short shafts 212 extend into the corresponding side of the first chamber 207 and are fixedly mounted with the threaded rod 213. The threaded rod 213 is threadedly connected to the support platform 210. By rotating, the support platform 210 can be moved smoothly along the axial direction, realizing the synchronous inward or outward movement of the two support platforms 210, precisely adjusting the bending fulcrum position of the spring plate 208, and thus adjusting the elastic force. The outer diameter of the threaded rod 213 is threaded to the middle of the corresponding side support platform 210. The threaded connection ensures that the support platform 210 moves smoothly without deviation when the threaded rod 213 rotates. The threaded structure has a self-locking function, which can fix the adjustment position of the support platform 210 and prevent the support platform 210 from shifting due to force after adjustment, thus ensuring the stability of the jacking force.

[0027] Furthermore, driven bevel gears 214 are fixedly installed on the inner ends of the short shaft 212. The driven bevel gears 214 mesh with the driving bevel gears 217, converting the rotational motion of the driving bevel gears 217 into their own rotational motion, thereby driving the short shaft 212 and the threaded rod 213 to rotate. The driven bevel gears 214 on both sides are symmetrically arranged to ensure synchronous transmission on both sides and consistent movement of the support platform 210. An internal hexagonal adjusting nut 215 is movably installed on one side of the upright 203. The internal hexagonal adjusting nut 215 serves as the operating interface for adjusting the jacking force, is compatible with commonly used internal hexagonal wrenches, is easy to operate, requires no complex professional equipment, and can easily complete the jacking force adjustment on the construction site, adapting to the correction needs of different types of embedded parts. A rotating shaft 216 is fixedly installed on the inner end of the internal hexagonal adjusting nut 215. The rotating shaft 216 connects the internal hexagonal adjusting nut 215 and the driving bevel gear 217, which can accurately transmit the rotational force of the internal hexagonal adjusting nut 215 to the driving bevel gear 217. Its structure is strong enough to effectively withstand the torque during the adjustment process and ensure stable transmission. The end of the rotating shaft 216 extends into the interior of the second chamber 211 and is fixedly installed with the driving bevel gear 217. The driving bevel gear 217, as the transmission core, can convert the unidirectional rotational motion of the rotating shaft 216 into the synchronous rotational motion of the driven bevel gears 214 on both sides by meshing with them, thereby realizing the bidirectional symmetrical adjustment of the thrust. Both ends of the driving bevel gear 217 are meshed with the inner ends of the two driven bevel gears 214. The meshing connection ensures the stability and synchronicity of the transmission, transmits large torque, and has no power loss during adjustment. It ensures that the rotation speed of the threaded rods 213 on both sides is consistent, the support platform 210 moves synchronously, the elastic force on both sides of the spring plate 208 is balanced, and the pushing force of the arc-shaped push plate 206 is uniform.

[0028] Working principle: Step 1: Adjustment and Correction. First, measure the position of the embedded part using a total station to determine the type and specific value of the deviation. After completion, fix the channel steel support 201 to the concrete base with expansion bolts according to the specific position of the embedded part, ensuring that the channel steel support 201 is level. Then, start the hydraulic cylinder 202. The hydraulic cylinder 202 drives the internal piston rod to move, which in turn moves the upright 203 and the arc-shaped push plate 206. When the arc-shaped push plate 206 contacts the embedded part, the hydraulic cylinder 202 continues to drive the piston rod to move, applying a uniform pushing force to the embedded part for correction. When the arc-shaped push plate 206 applies a pushing force to the embedded part, it will drive the rotating frame 204 to rotate through the connecting plate 205. The rotating frame 204 will bend the spring plate 208 through the pressure roller 209. The elastic force generated by the bent spring plate 208 will apply pressure to the embedded part through the connecting plate 205 and the arc-shaped push plate 206 to achieve the correction. The pressure roller 209 bends the spring plate 208 while applying pressure to the embedded part. When the spring plate 208 is in use, relative sliding occurs on its surface, compensating for the change in elastic force as the bending degree of the spring plate 208 changes. This ensures that the pushing force applied by the push plate to the embedded part remains stable, effectively preventing secondary deformation caused by uneven stress on the embedded part. In addition, the internal hexagonal wrench can be used to rotate the internal hexagonal adjusting nut 215, driving the rotating shaft 216 and the driving bevel gear 217 to rotate. The rotating driving bevel gear 217 drives the driven bevel gears 214 and the short shaft 212 on both sides to rotate, thereby driving the two threaded rods 213 to rotate. When the threaded rods 213 rotate, they will drive the support platforms 210 on both sides to move inward or outward synchronously. When the position of the support platform 210 changes, the bending fulcrum of the spring plate 208 changes accordingly. At this time, the elastic force generated by the bending of the spring plate 208 will also change accordingly, and the pushing force of the push plate on the embedded part will also change accordingly, which facilitates the position correction of different types of embedded parts. Step 2: Adaptive connection fixation. Adjust the shape of the correction connection component 1 according to the specific deviation type. If the embedded part has a small positional deviation, fold the second hinged steel plate 103 and the first hinged steel plate 102 and weld them together. Place them at a 90° angle with the main pad steel plate 101 to form the patch plate connection structure 3. Drill holes at the corresponding positions in the concrete base. Clean the dust in the holes with a high-pressure cleaning tool. Insert chemical bolts with pull-out detection interfaces. After the agent has cured according to the ambient temperature, weld the welding groove 107 of the patch plate connection structure 3 to the embedded part. Tighten the other end through the first waist hole 104 and the chemical bolt. Lock the first rib rod 111 and the second rib rod 112 with the locking bolt 113 to enhance the connection rigidity. If the embedded part is significantly misaligned, the second hinged steel plate 103 and the first hinged steel plate 102 are folded, welded, and laid flat to be flush with the surface of the main pad steel plate 101 to form a transition plate connection structure 4. The first waist hole 104 is aligned with the embedded part, and the second waist hole 105 and the third waist hole 106 are combined and aligned with the connector at the designed position. The connector is then fixed with bolts and welded to form a reliable force transmission path.If the embedded part is tilted, the second hinged steel plate 103 and the first hinged steel plate 102 are placed at a certain angle and then placed at a certain angle with the main pad steel plate 101 to form a wedge-shaped pad connection structure 5. The angle of the second hinged steel plate 103 is adjusted according to the tilt angle, and the welding groove 107 is attached to the embedded part for full welding. The rectangular pad plate 108 is then fixed to the concrete base through bolts and bolt mounting holes 109 to prevent it from sliding under force.
