In diaphragm wall construction, the fabrication and installation of the reinforcing cage is one of the key processes, and its quality directly affects the safety and durability of the project. Reinforcing cage fabrication technology has evolved from on-site manual binding to factory prefabrication, and then to mechanized and automated processing, with continuous improvements in processing efficiency and quality control.

[0003] Currently, existing methods for segmented rebar cage assembly have several shortcomings: temporary support devices have poor stability, making rebar cage segments prone to displacement and swaying, affecting assembly accuracy; manual adjustment and positioning are inefficient, labor-intensive, and difficult to ensure axial consistency between multiple segments; movement and adjustment of rebar cage segments during assembly are difficult, impacting overall construction progress. Particularly during segment assembly, the lack of effective limiting and guiding devices makes it difficult to quickly and accurately align adjacent segments, increasing the difficulty of welding operations. Furthermore, existing support structures often cannot simultaneously meet the requirements of stability and adjustability, making it difficult to achieve fine-tuning and positioning of rebar cage segments while ensuring support strength. These problems restrict the quality and efficiency of diaphragm wall rebar cage fabrication. Utility Model Content

[0023] Diaphragm walls, as an important foundation engineering technology, have been widely used in projects such as subway stations, deep foundation pit support, and underground utility tunnels. In diaphragm wall construction, the fabrication and installation of the reinforcing cage is one of the key processes, and its quality directly affects the safety and durability of the project. Reinforcing cage fabrication technology has evolved from on-site manual binding to factory prefabrication, and then to mechanized and automated processing, with continuous improvements in processing efficiency and quality control.

[0024] Currently, the fabrication of diaphragm wall reinforcement cages generally adopts a segmented fabrication and on-site welding method. Due to the significant depth of diaphragm walls, the overall length of the reinforcement cage often reaches tens of meters. Limited by transportation conditions and hoisting capacity, the reinforcement cage typically needs to be fabricated in multiple segments, which are then welded together section by section on the construction site or fabrication area. During the welding process, operators need to precisely position and fix the ends of adjacent reinforcement cage segments to ensure accurate alignment of the reinforcement bars at the joint, meeting welding quality requirements. To achieve stable support and accurate positioning of the reinforcement cage segments, temporary supports, wooden blocks, and other auxiliary tools are typically used on the construction site, and the welding preparation work is completed through manual adjustment and fixing.

[0025] However, existing methods for segmented rebar cage assembly have several shortcomings: temporary support devices have poor stability, making rebar cage segments prone to displacement and swaying, affecting assembly accuracy; manual adjustment and positioning are inefficient, labor-intensive, and difficult to ensure axial consistency between multiple segments; movement and adjustment of rebar cage segments during assembly are difficult, impacting overall construction progress. Particularly during segment assembly, the lack of effective limiting and guiding devices makes it difficult to quickly and accurately align adjacent segments, increasing the difficulty of welding operations. Furthermore, existing support structures often cannot simultaneously meet the requirements of stability and adjustability, making it difficult to achieve fine-tuning and positioning of rebar cage segments while ensuring support strength. These problems restrict the quality and efficiency of diaphragm wall rebar cage fabrication.

[0026] To solve this technical problem, this utility model proposes a segmented connection device for processing steel cages for underground continuous walls.

[0027] Please see Figure 1 and Figure 3In one embodiment of this utility model, the underground continuous wall reinforcement cage includes multiple reinforcement cage segments 10. The segmented connection device for processing the underground continuous wall reinforcement cage includes a support structure 100, a guide structure 200, and multiple limiting members 400. The top of the support structure 100 is provided with a first sliding groove 101, which extends horizontally. The guide structure 200 is disposed above the support structure 100, and the bottom of the guide structure 200 is provided with a second sliding groove 201 corresponding to the position of the first sliding groove 101. The extension direction of the second sliding groove 201 is the same as that of the first sliding groove 101. The extension direction of the first slide groove 101 is consistent, and a receiving gap 301 is formed between the first slide groove 101 and the second slide groove 201; a plurality of limiting members 400 are arranged at intervals along the extension direction of the first slide groove 101, and the plurality of limiting members 400 are all arranged between the support structure 100 and the guide structure 200; wherein, each limiting member 400 extends vertically, the top end of each limiting member 400 slides and engages with the second slide groove 201, the bottom end of each limiting member 400 slides and engages with the first slide groove 101, and each limiting member 400 is sleeved on the end of each steel cage segment 10.

[0028] It should be noted that the supporting structure 100 refers to the basic frame that supports the reinforcing cage segment 10. Specifically, it can be implemented by combining a metal base 110 with a groove and a supporting rail 121, with the groove providing a horizontal movement track for the limiting member 400. The guide structure 200 refers to the positioning mechanism set above the supporting structure 100. Specifically, it can be implemented by combining a guide rail 231 with a second groove 201 and a bracket 210, with the upper and lower grooves working together to form the movement trajectory of the limiting member 400. The limiting member 400 refers to the positioning element that constrains the position of the reinforcing cage segment 10. Specifically, it can be implemented by a sliding block with a sleeve, the inner diameter of which is adapted to the outer diameter of the main reinforcing bar of the reinforcing cage, and the end of the segment is fixed by the sleeve.

[0029] More specifically, during operation, the end of the rebar cage segment 10 is inserted into the sleeve of the limiting member 400. The bottom end of the limiting member 400 is embedded in the first sliding groove 101, and the top end is embedded in the second sliding groove 201. When the segment position needs to be adjusted, the operator can push the limiting member 400 along the sliding groove direction, causing the rebar cage segment 10 to move horizontally. The double-track structure formed by the upper and lower sliding grooves prevents the limiting member 400 from tilting, ensuring the verticality of the segment during movement. After adjacent segments are adjusted into place, the operator can directly perform welding operations through the receiving gap 301 between the two sliding grooves without removing the limiting device.

[0030] Compared to existing technologies, the current temporary support 210 only provides static support and cannot achieve controllable adjustment of segment positions. This solution, through the dynamic cooperation of the sliding groove and the limiting component 400, maintains support stability while giving the segments freedom of horizontal movement. Traditional wooden blocks require repeated disassembly and adjustment, while the limiting component 400 of this device can slide continuously along the sliding groove, significantly improving positioning efficiency. In addition, the guiding system formed by the upper and lower sliding grooves can automatically correct the segment axis, avoiding the cumulative errors caused by manual adjustment.

[0031] In the technical solution provided by this utility model, the accurate positioning and stable support of the rebar cage segments 10 during the docking process are achieved through the first sliding groove 101 of the supporting structure 100, the second sliding groove 201 of the guiding structure 200, and the limiting member 400 that slides and cooperates with the first sliding groove 101 and the second sliding groove 201. The sliding mechanism of the limiting member 400 makes it more convenient to adjust the position of each rebar cage segment 10. The double sliding groove structure formed by the first sliding groove 101 and the second sliding groove 201 can effectively prevent the rebar cage segments 10 from shifting, and the accommodating gap 301 provides sufficient operating space for welding operations. This can significantly reduce the number of manual adjustments, ensure the axial consistency of multiple rebar cage segments 10, and improve the work efficiency and quality in the segmented docking process of the underground continuous wall rebar cage.

[0032] Please continue reading. Figure 1 And see Figure 2 In an embodiment of this utility model, the support structure 100 includes a base 110 and a support component 120. The base 110 extends vertically, and the support component 120 extends horizontally. The top of the support component 120 is recessed downward to form a first groove 101, and the support component 120 is connected to the base 110.

[0033] It should be noted that the base 110 refers to a load-bearing structure extending vertically, which can be implemented using a welded steel plate frame or precast concrete blocks, providing stable foundation support for the support component 120. The support component 120 refers to a load-bearing component extending horizontally, which can be implemented using I-beams or channel steel profiles. Its top is recessed downwards to form a first sliding groove 101, used for sliding engagement with the bottom end of the limiting member 400. The first sliding groove 101 refers to a guide structure 200 formed by the downward recess of the top of the support component 120, which can be implemented using an arc-shaped or rectangular cross-section groove, used to guide the limiting member 400 to slide horizontally.

[0034] More specifically, the base 110 enhances overall stability through its vertically extending structure, while the support assembly 120 distributes the load of the reinforcing cage segment 10 through its horizontally extending layout. A first groove 101 formed by a recess at the top of the support assembly 120 slides in conjunction with the bottom end of the limiting member 400, allowing the limiting member 400 to move along a predetermined trajectory when adjusting the position of the reinforcing cage segment 10. The base 110 and the support assembly 120 are fixedly connected by welding or bolts to form a rigid support system, preventing deformation caused by uneven load distribution.

[0035] This application significantly improves support stability through a rigid vertical and horizontal connection using a combined structure of base 110 and support component 120. The guiding function of the first slide groove 101 replaces the manual, repeated adjustment of the position of the limiting component 400, reducing positioning errors. This solves the problem of insufficient stability in existing support devices. The combined structure of base 110 and support component 120 achieves stable load-bearing of the reinforcing cage segment 10, while the guiding characteristics of the first slide groove 101 simplify the adjustment process of the limiting component 400, improving docking accuracy and operational efficiency.

[0036] Please continue reading. Figure 1 and Figure 2 In an embodiment of this utility model, the support component 120 includes a support rail 121 and a first reinforcing rib 122. Both the support rail 121 and the first reinforcing rib 122 extend in the horizontal direction. The support rail 121 is connected to the base 110. The top of the support rail 121 is recessed downward to form a first groove 101. The first reinforcing rib 122 is positioned between the base 110 and the support rail 121, corresponding to the position of the first groove 101.

[0037] It should be noted that the support rail 121 refers to a load-bearing component extending horizontally, which can be made of I-beams or channel steel. It is used to support the weight of the limiting member 400 and the reinforcing cage segment 10, and provides guidance for the sliding of the limiting member 400 through the first sliding groove 101 formed by the top recess. The first reinforcing rib 122 refers to a reinforcing component set between the base 110 and the support rail 121. It can be made of angle steel or welded steel plates, and is used to enhance the bending stiffness and load-bearing capacity of the support rail 121, preventing the support rail 121 from deforming or breaking under load.

[0038] More specifically, the support rail 121 is fixedly connected to the base 110 via a horizontally extending structure, forming a stable load-bearing foundation. The first groove 101, formed by a recess at its top, can accommodate the bottom end of the limiting member 400 and guide its sliding. The first reinforcing rib 122 is located between the base 110 and the support rail 121, and is fixed to both by welding or bolting. This reduces the risk of localized deformation of the support rail 121 by dispersing stress distribution when it bears the load of the reinforcing cage segment 10. For example, the support rail 121 can be made of channel steel with its opening facing upwards to form an arc-shaped groove, while the first reinforcing rib 122 can be made of angle steel of the same width as the channel steel, spaced apart along the length of the groove to improve the overall bending resistance of the structure.

[0039] This application adds a first reinforcing rib 122, forming multi-point reinforcement between the support rail 121 and the base 110. This not only improves the deformation resistance of the support rail 121 but also extends the service life of the device. It effectively solves the problem of positioning misalignment of the reinforcing cage segment 10 caused by insufficient rigidity in the existing support structure 100. Through the synergistic effect of the support rail 121 and the first reinforcing rib 122, it ensures the stable sliding of the limiting member 400 within the groove, thereby improving the accuracy and efficiency of the rebar cage segment 10 connection and reducing the number of manual adjustments.

[0040] Please continue reading. Figure 1 and Figure 2 In an embodiment of this utility model, a first T-shaped through groove 111 is provided on one side of the base 110. The first T-shaped through groove 111 extends horizontally. The top of the base 110 is recessed downward to form a first clearance opening 112. The first clearance opening 112 communicates with the first T-shaped through groove 111. The support rail 121 and the first reinforcing rib 122 are both housed in the first T-shaped through groove 111. The first clearance opening 112 is positioned corresponding to the first sliding groove 101 and communicates with the first sliding groove 101.

[0041] It should be noted that the first T-shaped through groove 111 refers to a T-shaped groove structure extending horizontally along the base 110. Specifically, it can be achieved by machining a groove on the side of the base 110 to accommodate the installation and fixation of the support rail 121 and the first reinforcing rib 122. The first clearance opening 112 refers to an opening area formed by a downward indentation at the top of the base 110. Specifically, it can be formed by milling, and its position corresponds to the first sliding groove 101, providing space for the bottom end of the limiting member 400 to slide within the first sliding groove 101. The support rail 121 refers to a load-bearing component extending horizontally, specifically made of channel steel or custom profiles. Its top is recessed to form the first sliding groove 101, guiding the sliding trajectory of the bottom end of the limiting member 400. The first reinforcing rib 122 refers to a reinforcing structure located between the support rail 121 and the base 110. Specifically, it can be fixed by welding steel plates or bolting, enhancing the connection strength between the support rail 121 and the base 110.

[0042] More specifically, a horizontally extending first T-shaped through groove 111 is machined on the side of the base 110, and the support rail 121 and the first reinforcing rib 122 are fixed by being embedded in this through groove. A first clearance opening 112 at the top of the base 110 communicates with the first T-shaped through groove 111, exposing the first sliding groove 101 at the top of the support rail 121 through the clearance opening, providing sliding space for the bottom end of the limiting member 400. The support rail 121 and the base 110 are reinforced by the first reinforcing rib 122, forming a stable support system. When the bottom end of the limiting member 400 slides along the first sliding groove 101, the clearance opening prevents the top structure of the base 110 from interfering with the movement of the limiting member 400.

[0043] This solution achieves embedded installation of the support rail 121 and the base 110 through the first T-shaped through groove 111. Combined with the spatial clearance design of the first clearance opening 112, it ensures structural stability and provides ample operating space for the sliding adjustment of the limiting component 400. This solves the problem of swaying of the rebar cage segment 10 caused by insufficient connection strength in the traditional support structure 100. Furthermore, the connection design between the clearance opening and the sliding groove allows the limiting component 400 to be adjusted without disassembling the base 110 during the adjustment process, significantly improving the positioning efficiency and operational convenience of the rebar cage segment 10 docking.

[0044] Please continue reading. Figure 1 and Figure 2 In an embodiment of this utility model, the cross-section of the first slide groove 101 is arc-shaped, and the bottom end of each limiting member 400 is arc-shaped to match the first slide groove 101.

[0045] It should be noted that the arc-shaped structure refers to the continuously curved shape of the slide's cross-section, which can be achieved using a circular arc segment with a radius ranging from 200 to 500 mm, with its center of curvature located above the slide opening. The matching arc-shaped structure means that the bottom shape of the limiting component 400 forms a surface contact with the inner wall of the slide. Specifically, this can be achieved by casting or machining to ensure that the curvature of the bottom of the limiting component 400 matches the curvature of the slide.

[0046] More specifically, when the arc-shaped groove formed at the top of the supporting track 121 engages with the arc-shaped structure at the bottom of the limiting member 400, their contact surfaces form a continuous fit. When the reinforcing cage segment 10 needs to be adjusted laterally, the bottom end of the limiting member 400 slides along the arc surface of the groove, and the geometric matching of the contact surfaces ensures a uniform distribution of sliding resistance. For example, the groove can be hot-bent from Q345 steel, and the bottom of the limiting member 400 can be inlaid with an arc-shaped slider made of polymer material, achieving smooth movement through the guiding effect of the arc-shaped contact surface.

[0047] This design utilizes an arc-shaped contact surface to ensure uniform distribution of contact stress along the arc during sliding, while employing geometric self-guiding properties to eliminate slider offset. This effectively solves the jamming problem that occurs during the adjustment of the reinforcing cage segment 10, making the movement of the limiting component 400 more stable and controllable. The continuous guiding effect of the arc-shaped contact surface prevents angular deflection of the limiting component 400 during sliding, ensuring the axial alignment accuracy of the multi-segment reinforcing cage and reducing the wear rate of the sliding components.

[0048] Please continue reading. Figure 1 and Figure 2 In an embodiment of this utility model, the guide structure 200 includes a bracket 210, a connecting plate 220, and a guide component 230. The bracket 210 is framed outside the support structure 100. The connecting plate 220 extends vertically, and the guide component 230 extends horizontally. The bottom of the guide component 230 is recessed upward to form a second groove 201. The connecting plate 220 and the guide component 230 are both connected to the bracket 210. The guide component 230 and the connecting plate 220 are spaced apart above the support structure 100.

[0049] It should be noted that the bracket 210 refers to the frame structure surrounding the support structure 100, which can be formed by welding steel to create a rectangular frame. This provides the mounting base for the connecting plate 220 and the guide assembly 230 and enhances the overall structural stability. The connecting plate 220 is a plate-shaped component arranged vertically, which can be formed by cutting and machining steel plates. It is used to fix the guide assembly 230 to the bracket 210. The guide assembly 230 is a horizontally extending component including the guide rail 231 and the second reinforcing rib 232. It can be formed by welding a combination of channel steel and angle steel. The guide rail 231 forms the second groove 201 to cooperate with the sliding of the limiting member 400, and the second reinforcing rib 232 enhances the bending stiffness of the guide rail 231. The second groove 201 is a recessed structure located at the bottom of the guide rail 231, which can be formed by machining into an arc-shaped channel. It is used to form a sliding fit with the arc-shaped structure at the top of the limiting member 400.

[0050] More specifically, the bracket 210 forms a stable external frame by surrounding the support structure 100. The connecting plate 220 is vertically installed inside the bracket 210 and welded and fixed to the guide assembly 230. The guide rail 231 extends horizontally and has an arc-shaped groove machined at the bottom. The second reinforcing ribs 232 are spaced apart along the length of the guide rail 231 to improve the resistance to deformation. The top of the limiting member 400 is embedded in the second groove 201 and slides along its extension direction. The space between the bracket 210 and the support structure 100 provides a working passage for the operator. The spaced arrangement of the connecting plate 220 and the guide assembly 230 ensures that the limiting member 400 remains vertical during sliding. When adjusting the position of the rebar cage segment 10, the limiting member 400 moves smoothly in the second groove 201. The frame connection between the bracket 210 and the support structure 100 effectively suppresses the overall shaking of the device.

[0051] This solution combines the independently configured guide component 230 with the bracket 210, giving the chute system modular installation characteristics and facilitating the adjustment of the guide rail 231 position according to the size of the rebar cage. It effectively solves the problem of positioning deviation caused by the easy swaying of the support structure 100 during rebar cage docking. The combined structure of the bracket 210 and guide component 230 forms a stable sliding guide system, ensuring that the limiting component 400 maintains its predetermined trajectory during adjustment. The vertical connection between the connecting plate 220 and the guide component 230 enhances the overall rigidity of the device, avoiding local deformation caused by uneven stress. The coordinated design of the guide rail 231 and the second reinforcing rib 232 ensures smooth sliding while significantly improving the load-bearing capacity of the chute structure, adapting to the docking requirements of rebar cage segments 10 of different weights.

[0052] Please continue reading. Figure 1 and Figure 2In an embodiment of this utility model, the guide component 230 includes a guide rail 231 and a second reinforcing rib 232. Both the guide rail 231 and the second reinforcing rib 232 extend in the horizontal direction. Both the guide rail 231 and the second reinforcing rib 232 are connected to the connecting plate 220. Both the connecting plate 220 and the second reinforcing rib 232 are connected to the bracket 210. The bottom of the guide rail 231 is recessed upward to form a second groove 201. The second reinforcing rib 232 is positioned between the guide rail 231 and the bracket 210, corresponding to the position of the second groove 201.

[0053] It should be noted that the guide rail 231 refers to a load-bearing component extending horizontally, which can be made of channel steel or I-beams. Its recessed bottom forms a sliding groove structure that provides a sliding track for the top of the limiting component 400. The second reinforcing rib 232 refers to a supporting component located between the guide rail 231 and the bracket 210, which can be made of angle steel or welded steel plates, used to enhance the load-bearing capacity of the connection between the guide rail 231 and the bracket 210. The connecting plate 220 refers to a vertical component connecting the bracket 210 and the guide assembly 230, which can be made of rectangular steel plates and fixedly connected to the bracket 210 by bolts or welding. The bracket 210 refers to the external frame surrounding the support structure 100, which can be a three-dimensional truss structure composed of welded steel sections, used to bear the overall weight of the guide assembly 230.

[0054] More specifically, the guide rail 231 is fixed to the side of the connecting plate 220 by welding or bolting. The second reinforcing rib 232 is arranged at intervals along the length of the guide rail 231, and its upper and lower ends are welded and fixed to the bottom of the guide rail 231 and the top of the bracket 210, respectively. The connecting plate 220 is vertically welded to the column of the bracket 210, and its height is adjustable to accommodate steel cage segments 10 of different sizes. The bottom of the bracket 210 is fixed to the ground foundation by anchor bolts to form a stable support system. When the steel cage segment 10 is erected in the receiving gap 301 by the limiting member 400, the guide rail 231 and the first sliding groove 101 of the support structure 100 form a vertically corresponding sliding track to ensure that the limiting member 400 remains vertical during horizontal movement.

[0055] This solution uses a second reinforcing rib 232 to form an integral load-bearing structure between the guide rail 231 and the support 210, effectively dispersing the lateral load generated during hoisting operations. The vertical connection between the connecting plate 220 and the support 210 prevents lateral displacement of the guide rail 231, and the arc-shaped fit between the second slide groove 201 and the top of the limiting member 400 reduces sliding friction resistance. This achieves a rigid connection between the guide rail 231 and the support 210, solving the positioning offset problem caused by insufficient structural rigidity in traditional devices. The second reinforcing rib 232 effectively suppresses the elastic deformation of the guide rail 231 during hoisting, allowing the limiting member 400 to slide smoothly along the predetermined track. The vertical fixing of the connecting plate 220 ensures the spatial positional accuracy of the guide assembly 230 and the support structure 100, reducing the workload of repeated manual adjustments.

[0056] Please continue reading. Figure 1 and Figure 2 In an embodiment of this utility model, a second T-shaped through groove 221 is provided on one side of the connecting plate 220. The second T-shaped through groove 221 extends horizontally. The top of the connecting plate 220 is recessed downward to form a second clearance opening 222. The second clearance opening 222 communicates with the second T-shaped through groove 221. The guide rail 231 and the second reinforcing rib 232 are both housed in the second T-shaped through groove 221. The second clearance opening 222 is positioned corresponding to the second sliding groove 201 and communicates with the second sliding groove 201.

[0057] It should be noted that the second T-shaped through groove 221 refers to a groove structure extending horizontally along the connecting plate 220, with a T-shaped cross-section. It can be formed on the side wall of the connecting plate 220 using machining or casting processes. It accommodates the guide rail 231 and the second reinforcing rib 232, and provides space for the sliding of the limiting member 400. The second clearance opening 222 is an opening formed by a downward indentation at the top of the connecting plate 220, which can be achieved through milling or stamping. It connects the second T-shaped through groove 221 to the external space, facilitating observation and adjustment of the position of the limiting member 400 by the operator. The guide rail 231 is a rigid component extending horizontally, which can be a steel rail or aluminum alloy profile. Its bottom is concave upward to form a second sliding groove 201, providing a guide path for the sliding of the top of the limiting member 400. The second reinforcing rib 232 is a support structure 100 set between the guide rail 231 and the connecting plate 220. It can be a welded or bolted steel plate, used to enhance the bending strength and stability of the guide rail 231.

[0058] More specifically, the guide rail 231 and the second reinforcing rib 232 are integrally embedded in the second T-shaped through groove 221, forming a communication structure with the second slide groove 201 through the second clearance opening 222. When the top of the limiting member 400 moves along the second slide groove 201, the operator can directly observe the sliding state of the limiting member 400 through the second clearance opening 222 and make fine adjustments to the position of the guide rail 231 using tools. The T-shaped cross-section design of the second T-shaped through groove 221 allows the guide rail 231 to distribute stress to the overall structure of the connecting plate 220 through the second reinforcing rib 232 when bearing the load of the reinforcing cage segment 10, avoiding local deformation. At the same time, the existence of the second clearance opening 222 allows debris or foreign objects generated by the limiting member 400 during sliding to be discharged through the opening, reducing the risk of jamming.

[0059] This design integrates the guide rail 231 and the second reinforcing rib 232 within the second T-shaped through-slot 221. This protects the integrity of the sliding components while retaining necessary operating space through the second clearance opening 222. This allows the adjustment of the limiting component 400 to be completed without disassembling the guide structure 200, significantly improving the maintainability of the device. The integrated structure of the guide rail 231 and the connecting plate 220 ensures the sliding accuracy of the limiting component 400 while effectively preventing interference from the external environment. The coordinated design of the second T-shaped through-slot 221 and the second clearance opening 222 ensures stable guiding performance during long-term use, reducing docking errors caused by structural deformation or foreign object accumulation, thereby improving the reliability and continuity of the rebar cage segment 10 docking operation.

[0060] Please continue reading. Figure 1 and Figure 2 In an embodiment of this utility model, the cross-section of the second slide groove 201 is arc-shaped, and the top of each limiting member 400 is arc-shaped to match the second slide groove 201.

[0061] It should be noted that the arc-shaped cross-section of the second slide groove 201 refers to the continuous curved shape of its cross-sectional profile. This can be achieved through stamping or machining, and its radius of curvature matches the arc shape of the top of the limiting member 400. Furthermore, the arc-shaped structure at the top of the limiting member 400 that matches the second slide groove 201 means that the top of the limiting member 400 has a curved surface that complements the shape of the inner wall of the slide groove. This can be achieved through casting or CNC machining. This structure reduces the frictional resistance of the contact surface during sliding.

[0062] More specifically, the guide rail 231 forms a sliding fit with the arc-shaped structure at the top of the limiting member 400 through the second sliding groove 201. When the limiting member 400 moves in the horizontal direction, the arc-shaped contact surface can disperse the stress concentration during the sliding process. The arc-shaped mating surface between the guide rail 231 and the limiting member 400 is in continuous curved surface contact, which enables the limiting member 400 to maintain a stable movement trajectory when adjusting its position, avoiding positioning deviations caused by local jamming.

[0063] In some specific embodiments, the radius of curvature of the arc-shaped cross-section of the second groove 201 can be from 50 mm to 200 mm, for example, a standard radius of 100 mm can be used to accommodate limit members 400 of different sizes. The arc-shaped structure at the top of the limit member 400 can be formed by welding an arc-shaped steel plate or by integral casting, and its surface can be further polished to reduce the coefficient of friction.

[0064] This solution, through the design of an arc-shaped contact surface, ensures a more uniform force distribution during the sliding process, significantly reducing frictional loss and improving the accuracy of the position adjustment of the limiting component 400. It effectively solves the problem of uneven movement of the limiting component 400 during the docking of the rebar cage segments 10, reduces resistance during manual adjustment, and improves the efficiency of the docking operation. The guiding fit of the arc-shaped structure also extends the service life of the slide and the limiting component 400, preventing a decrease in positioning accuracy due to localized wear.

[0065] Please continue reading. Figure 1 and Figure 3 And see Figure 4 In the embodiments of this utility model, the limiting member 400 has a polygonal structure, a weight reduction hole 401 is provided at the center of the limiting member 400, and multiple limiting holes 402 are provided at the positions of multiple joints of each steel cage segment 10, and each joint can be detachably inserted into the corresponding limiting hole 402.

[0066] It should be noted that the polygonal structure of the limiting component 400 refers to the fact that the outer contour of the limiting component 400 has a closed shape formed by at least three straight sides. Specifically, it can be implemented using a rectangular, hexagonal, or octagonal structure. The polygonal structure can form a stable support surface through planar contact, preventing rolling or deflection. The weight-reducing hole 401 refers to a through hole penetrating the central area of ​​the limiting component 400. Specifically, it can be implemented using a circular, square, or polygonal hole structure. By reducing material usage, the overall weight of the limiting component 400 is reduced, facilitating manual handling and position adjustment. The limiting hole 402 refers to multiple through holes distributed circumferentially along the limiting component 400. Specifically, it can be implemented using circular holes matching the outer diameter of the joint of the reinforcing cage segment 10 or irregularly shaped holes with grooves. Precise positioning is achieved by constraining the radial displacement of the joint.

[0067] More specifically, when the limiting member 400 adopts a polygonal structure, its outer wall forms a stable planar support with the contact surface of the supporting structure 100 and the guide structure 200, avoiding displacement caused by rolling; the weight-reducing hole 401 is set in the center position to balance the weight distribution and reduce the physical exertion of the operator during adjustment; multiple limiting holes 402 are arranged circumferentially along the limiting member 400, and their number and position correspond to the joint distribution of the rebar cage segment 10. Quick positioning is achieved by inserting each joint into the corresponding limiting hole 402. During the docking process, after the limiting member 400 moves to the target position along the slide groove through sliding adjustment, the operator can directly insert the joint of the rebar cage segment 10 into the limiting hole 402 to complete the initial fixation and ensure that the axes of each segment are aligned.

[0068] This solution optimizes ergonomics through weight reduction design. Existing temporary fixing methods rely on manual adjustment, making it difficult to ensure synchronous alignment of multiple joints. However, the distribution pattern of the 402-hole array enables synchronous positioning of multiple joints. This solves the problems of easy displacement of the limiting device, cumbersome operation, and difficulty in synchronous alignment of multiple joints during existing rebar cage docking processes. It achieves rapid and accurate positioning of the rebar cage segment 10, reduces the labor intensity of manual adjustment, and improves docking efficiency and quality stability.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
