Description

Technical Field

[0001] This utility model relates to the field of steel cage construction technology, and in particular to an auxiliary tilting device for steel cages. Background Technology

[0002] With the widespread application of reinforced concrete structures in construction projects, the optimization of the prefabrication process of steel cages, as key load-bearing components, has a decisive impact on project quality and construction progress.

[0003] Currently, the orientation change of rebar cages mainly relies on the coordinated operation of large lifting equipment and manual labor. In practice, construction workers need to use cranes or gantry cranes to fix one end of the rebar cage using wire ropes or specialized lifting tools, and then use the lifting force to drive the rebar cage to rotate and flip around its bottom edge. During this process, multiple workers must work closely together in the bottom area of ​​the rebar cage, manually controlling the flipping angle and speed to prevent structural instability and collapse or a hard collision between the bottom end and the ground.

[0004] However, this traditional method has significant drawbacks: on the one hand, the scheduling and operation of large lifting equipment requires a large amount of space, and equipment coordination is complex and costly; on the other hand, there are too many manual interventions, requiring workers to be in high-risk work areas for extended periods, resulting in extremely high labor intensity and prominent safety hazards. Crucially, when the cage is tilted and nearing its upright position, the bottom end of the rebar cage often directly impacts the ground, causing bending deformation of the rebar ends or cracking and damage to the concrete cover. This not only reduces structural durability but may also lead to subsequent installation quality problems. Furthermore, the entire tilting process lacks stability and controllability, and the operating rhythm is difficult to accurately control, resulting in low tilting efficiency and severely restricting the large-scale production progress of precast rebar cages. Utility Model Content

[0005] The main purpose of this utility model is to propose an auxiliary turning device for steel cages, which aims to solve the problems in the existing technology of steel cage turning operations relying on large lifting equipment, high labor intensity, uncontrollable turning process, and easy damage to the ends of steel cages, so as to realize the simplification, safety and efficiency of steel cage posture adjustment.

[0006] To achieve the above objectives, the present invention proposes an auxiliary tilting device for reinforcing cages, comprising: A prefabricated support, wherein a portion of the prefabricated support extends horizontally to form a support section, and another portion of the prefabricated support is bent vertically upward from the end of the support section to form a connecting section; A first limiting component is connected to the connecting segment. The first limiting component is disposed near the top of the connecting segment, and the first limiting component cooperates with the connecting segment to form a connecting space. A connecting component is disposed in the connecting space, and the end of the reinforcing cage extends into the connecting space and is detachably connected to the connecting segment through the connecting component; A second limiting component is connected to the support segment; The support section is used to cause the steel cage to rotate around the support section when the steel cage is driven by an external force, so as to adjust the posture of the steel cage.

[0007] In one embodiment, the transition section between the support section and the connecting section has an arc-shaped structure that arches outward toward the outside of the prefabricated support.

[0008] In one embodiment, the precast support includes a plurality of precast main bars, which are spaced apart along the width or length direction of the steel cage. The first limiting component and the second limiting component are connected between two adjacent precast main bars. A portion of each precast main bar extends horizontally to form the support section, and another portion of each precast main bar is bent vertically upward from the end of the support section to form the connecting section.

[0009] In one embodiment, the first limiting component includes a plurality of connecting ribs, which are arranged at vertical intervals. The plurality of connecting ribs cooperate with the connecting segment to form the connecting space, and the two ends of each connecting rib are respectively connected to two adjacent precast main ribs.

[0010] In one embodiment, the distance between two adjacent precast main reinforcement bars is D, where 200mm≤D.

[0011] In one embodiment, the connecting assembly includes a plurality of binding wires, which are spaced apart in the connecting space along the extension direction of the connecting segment. The end of the reinforcing cage extends into the connecting space and is detachably connected to the connecting segment through the plurality of binding wires.

[0012] In one embodiment, the second limiting component includes a first layer of reinforcing bars, a second layer of reinforcing bars, and a third layer of reinforcing bars. The first layer of reinforcing bars, the second layer of reinforcing bars, and the third layer of reinforcing bars are connected to the support section in sequence from bottom to top vertically. The third layer of reinforcing bars is disposed at the end of the support section away from the connecting section. The first layer of reinforcing bars and the third layer of reinforcing bars both extend along the length or width direction of the reinforcing cage. A portion of the second layer of reinforcing bars is disposed between the support section and the third layer of reinforcing bars to form a reinforcing section. The reinforcing section extends along the extension direction of the support section. Another portion of the second layer of reinforcing bars is disposed at the end of the support section near the connecting section and extends along the length or width direction of the reinforcing cage.

[0013] In one embodiment, the included angle between the support segment and the connecting segment is 90°.

[0014] In one embodiment, the length of the support segment is H, where 500mm ≤ H.

[0015] In one embodiment, the length of the connecting segment is L, where 450mm ≤ L ≤ 512mm.

[0016] The technical solution of this utility model utilizes the L-shaped structure of the support section and connecting section of the prefabricated bracket to allow the reinforcing cage to rotate around the support section as its axis of rotation. When rotated to an upright position, the support section automatically switches to a horizontal support position, ensuring that the end of the reinforcing cage remains suspended above the ground. This effectively avoids the deformation or damage to the concrete cover caused by the direct impact of the reinforcing cage end with the ground in traditional rotation methods, thus guaranteeing the structural integrity and engineering quality of the reinforcing cage. The connection space formed by the first limiting component and the connecting section, combined with the connecting component, enables rapid fixing and release of the end of the reinforcing cage. Compared to traditional wire rope binding methods, this not only simplifies installation and disassembly operations and reduces the skill requirements for operators, but also avoids wear and localized stress concentration on the surface of the reinforcing cage during binding, reducing stress on the reinforcing bars. The second limiting component provides additional limiting during the initial stage of the flipping process, effectively preventing the steel cage from sliding or becoming unstable in the early stages of stress, thus further enhancing the controllability and stability of the flipping process. More importantly, the entire flipping process does not require the full intervention of large lifting equipment; only simple external force is needed to complete the attitude adjustment, significantly reducing equipment scheduling costs and site space occupation, and reducing the labor intensity and safety risks of multiple operators. Due to the fixed structure design of the prefabricated support, the components remain stably connected during the flipping process, without involving complex mechanical adjustments or frequent component disassembly and assembly, ensuring the reliability and service life of the device, while improving the overall efficiency of steel cage prefabrication production, and better meeting the dual requirements of modern prefabricated buildings for construction efficiency and quality.

[0024] With the widespread application of reinforced concrete structures in construction projects, the optimization of the prefabrication process of steel cages, as key load-bearing components, has a decisive impact on project quality and construction progress.

[0025] Currently, the orientation change of rebar cages mainly relies on the coordinated operation of large lifting equipment and manual labor. In practice, construction workers need to use cranes or gantry cranes to fix one end of the rebar cage using wire ropes or specialized lifting tools, and then use the lifting force to drive the rebar cage to rotate and flip around its bottom edge. During this process, multiple workers must work closely together in the bottom area of ​​the rebar cage, manually controlling the flipping angle and speed to prevent structural instability and collapse or a hard collision between the bottom end and the ground.

[0026] However, this traditional method has significant drawbacks: on the one hand, the scheduling and operation of large lifting equipment requires a large amount of space, and equipment coordination is complex and costly; on the other hand, there are too many manual interventions, requiring workers to be in high-risk work areas for extended periods, resulting in extremely high labor intensity and prominent safety hazards. Crucially, when the cage is tilted and nearing its upright position, the bottom end of the rebar cage often directly impacts the ground, causing bending deformation of the rebar ends or cracking and damage to the concrete cover. This not only reduces structural durability but may also lead to subsequent installation quality problems. Furthermore, the entire tilting process lacks stability and controllability, and the operating rhythm is difficult to accurately control, resulting in low tilting efficiency and severely restricting the large-scale production progress of precast rebar cages.

[0027] To solve this technical problem, this utility model proposes an auxiliary flipping device for steel cages.

[0028] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of this utility model, the auxiliary tilting device for a rebar cage includes a prefabricated support 100, a first limiting component 200, a connecting component 300, and a second limiting component 400. A portion of the prefabricated support 100 extends horizontally to form a support section 111, and another portion of the prefabricated support 100 bends vertically upward from the end of the support section 111 to form a connecting section 112. The first limiting component 200 is connected to the connecting section 112 and is disposed near the top of the connecting section 112. The first limiting component 200 and the connecting section 112 cooperate to form a connecting space 201. The connecting component 300 is disposed in the connecting space 201, and the end of the rebar cage 10 extends into the connecting space 201 and is detachably connected to the connecting section 112 through the connecting component 300. The second limiting component 400 is connected to the support section 111. The support section 111 is used to tilt the rebar cage 10 around the support section 111 when the rebar cage 10 is driven by an external force, so as to adjust the posture of the rebar cage 10.

[0029] In practical applications, the prefabricated support 100 can be understood as a structural component with a specific geometric shape. Its main function is to support and guide the rebar cage 10 during its flipping process through the combination of the support section 111 and the connecting section 112. Specifically, the support section 111 can be made of steel plate, structural steel, or other materials with sufficient strength and is fixed to the foundation structure by welding or bolting. The connecting section 112 can be achieved through bending or segmented splicing, and its purpose is to provide a stable connection point for installing the first limiting component 200 and the connecting component 300.

[0030] Furthermore, the first limiting component 200 can achieve its function in various ways. For example, the first limiting component 200 can form a connecting space 201 by setting multiple spaced limiting plates, which can be fixed to the connecting section 112 by welding or snap-fit. In addition, the first limiting component 200 can also be implemented by setting an adjustable limiting rod, the position and angle of which can be adjusted according to the specific dimensions of the reinforcing cage 10, thereby adapting to reinforcing cages 10 of different specifications.

[0031] The function of the connecting assembly 300 is to enable a detachable connection between the end of the rebar cage 10 and the connecting section 112. Specifically, the connecting assembly 300 can achieve this by setting multiple clamps, which can employ manual locking or quick-release mechanisms to facilitate quick installation and disassembly by operators. Alternatively, the connecting assembly 300 can also be implemented by setting hooks or slots, allowing the end of the rebar cage 10 to be secured by inserting the hooks or slots.

[0032] The function of the second limiting component 400 is to provide additional limiting for the rebar cage 10 during the initial stage of flipping. In practical applications, the second limiting component 400 can be implemented by setting multiple stops, which can be fixed to the surface of the support section 111 and adjusted in position to accommodate rebar cages 10 of different lengths. Alternatively, the second limiting component 400 can also be implemented by setting an elastic buffer, which can provide a certain buffering effect when the rebar cage 10 is subjected to force, thereby reducing the impact of the impact force on the device.

[0033] The innovation of this application lies in using the support section 111 of the prefabricated bracket 100 as the rotation axis, ensuring that the end of the rebar cage 10 remains suspended during the flipping process, preventing direct impact with the ground and resulting deformation. Simultaneously, the cooperation of the first limiting component 200 and the connecting component 300 enables rapid fixing and release of the end of the rebar cage 10, reducing damage to the rebar cage 10 structure caused by traditional binding methods. Furthermore, the second limiting component 400 further enhances the stability of the flipping process, reducing the need for manual intervention, thereby significantly improving operational safety and efficiency.

[0034] The working principle of this embodiment is as follows: The auxiliary flipping device adjusts the posture of the reinforcing cage 10 through the cooperation of the support section 111 and the connecting section 112 of the prefabricated bracket 100. Part of the prefabricated bracket 100 extends horizontally to form the support section 111, and another part bends vertically upward from the end of the support section 111 to form the connecting section 112. When the reinforcing cage 10 is not flipped, the support section 111 is vertical, and the connecting section 112 is horizontal, facilitating the initial placement of the reinforcing cage 10. Furthermore, a first limiting component 200 is connected to the connecting section 112 and positioned near its top, forming a connecting space 201 together with the connecting section 112. The end of the reinforcing cage 10 extends into this connecting space 201 and is detachably connected through the connecting component 300, thereby ensuring that the reinforcing cage 10 does not shift or fall off during the flipping process. A second limiting component 400 is connected to the support section 111, providing additional limiting during the initial flipping stage to prevent the reinforcing cage 10 from sliding or becoming unstable. When the reinforcing cage 10 is driven by an external force, the support section 111 acts as a rotation axis, causing the reinforcing cage 10 to rotate around it, adjusting its posture from a lying position to an upright position. At this time, the support section 111 is in a horizontal state, preventing the end of the reinforcing cage 10 from contacting the ground, while the connecting section 112 is in a vertical state, providing a stable support point for the reinforcing cage 10. Thus, the entire rotation process does not require the full intervention of large lifting equipment and can be completed with only simple external force, significantly reducing operational complexity and safety risks, while improving the stability and efficiency of the rotation process.

[0035] Please continue reading. Figures 1 to 3 In an embodiment of this utility model, the transition section 113 between the support section 111 and the connecting section 112 has an arc-shaped structure that arches outward toward the prefabricated bracket 100.

[0036] Specifically, the transition section 113 refers to the part between the support section 111 and the connecting section 112 used for force transmission and structural connection. It can be implemented using a curved bend, multi-segment curve splicing, or a gradually changing curvature geometry. In practical applications, the curved structure design effectively disperses stress concentration and avoids localized damage caused by sudden changes in rigidity, aiming to improve the overall stability and durability of the structure. Simultaneously, this design makes the movement trajectory of the steel cage 10 smoother during the flipping process, reducing the possibility of impact and swaying.

[0037] More specifically, the arc-shaped transition section 113 between the support section 111 and the connecting section 112 optimizes the force transmission path through its continuous geometry, resulting in a more uniform force distribution during the rotation of the reinforcing cage 10. This design not only avoids structural damage caused by stress concentration at right-angle bends but also significantly reduces the risk of the reinforcing cage 10's ends colliding with the ground. Furthermore, the arc-shaped transition section 113 works organically with the overall structure of the precast support 100, further enhancing the device's load-bearing capacity and deformation resistance. When the reinforcing cage 10 rotates around the support section 111, the arc-shaped transition section 113 ensures the smoothness of the rotation, thereby improving operational safety and controllability. This design is particularly suitable for construction scenarios requiring frequent adjustments to the reinforcing cage 10's posture, providing a reliable guarantee for efficient and safe rotation operations.

[0038] Please continue reading. Figure 1 In an embodiment of this utility model, the prefabricated support 100 includes a plurality of prefabricated main bars 110. The plurality of prefabricated main bars 110 are spaced apart along the width or length direction of the steel cage 10. The first limiting component 200 and the second limiting component 400 are connected between two adjacent prefabricated main bars 110. A portion of each prefabricated main bar 110 extends horizontally to form a support section 111, and another portion of each prefabricated main bar 110 is bent vertically upward from the end of the support section 111 to form a connecting section 112.

[0039] Specifically, the precast main reinforcement 110 refers to an independent unit constituting the main structure of the precast support 100. It can be made of high-strength steel and achieves the function of distributing load through modular design. Multiple precast main reinforcements 110 are spaced apart along the width or length direction of the steel cage 10. This design is based on actual construction needs and the spacing can be flexibly adjusted according to the specific specifications of the steel cage 10. The first limiting component 200 and the second limiting component 400 are connected between two adjacent precast main reinforcements 110. This connection method can make full use of the frame structure formed by adjacent main reinforcements and provide more stable anchoring points. The support section 111 refers to the part of the precast main reinforcement 110 that extends horizontally. Its function is to serve as the rotation axis when the steel cage 10 is flipped, ensuring that the flipping process is smooth and controllable. The connecting section 112 refers to the part of the precast main reinforcement 110 that bends upward from the end of the support section 111. Its purpose is to form a multi-point coordinated fixed space.

[0040] More specifically, this solution fundamentally enhances the load-bearing capacity and adaptability of the precast support 100 by decomposing it into a modular design of multiple independent precast main reinforcement bars 110. In practical applications, the spaced arrangement of multiple precast main reinforcement bars 110 ensures that the dynamic load generated during the flipping process is evenly distributed, avoiding stress concentration. When the steel cage 10 flips, each precast main reinforcement bar 110 independently shares the flipping moment, significantly improving the overall deformation resistance of the support. The first limiting component 200 and the second limiting component 400, relying on the stable frame formed by adjacent precast main reinforcement bars 110, not only enhance the connection stiffness but also effectively prevent the steel cage 10 from lateral slippage or connection loosening due to inertia during the flipping process. The support section 111, as the axis of rotation, combined with the even distribution of the precast main reinforcement bars 110, ensures that the steel cage 10 has a smooth trajectory when flipping around it, avoiding hard contact between the ends and the ground. The connecting section 112, through its multi-point collaborative design, provides a reliable fixing space for the end of the steel cage 10, ensuring that the attitude is controllable throughout the flipping process, while also simplifying the disassembly operation.

[0041] In summary, the aforementioned auxiliary tilting device, through the modular design of the prefabricated main rib 110, achieves a shift from passive load-bearing to active control, making the tilting process both efficient and safe.

[0042] Please continue reading. Figure 1 In an embodiment of this utility model, the first limiting component 200 includes a plurality of connecting ribs 210, which are arranged vertically at intervals. The plurality of connecting ribs 210 cooperate with the connecting segment 112 to form a connecting space 201, and the two ends of each connecting rib 210 are respectively connected to two adjacent precast main ribs 110.

[0043] The connecting ribs 210 are components used to construct the limiting structure and provide support. They can be made of steel bars, steel strips, or other materials with sufficient strength and rigidity. The arrangement of multiple connecting ribs 210 at vertical intervals allows for flexible adjustment of the spacing to accommodate the geometric characteristics of the ends of the reinforcing cage 10 of different specifications. This arrangement aims to distribute the dynamic load generated during the flipping process through multi-point support, avoiding structural deformation caused by localized stress concentration. Furthermore, the connecting space 201 is a semi-enclosed area formed by multiple connecting ribs 210 and connecting sections 112. Its purpose is to provide a tight enclosure for the ends of the reinforcing cage 10, preventing slippage or displacement during the flipping process.

[0044] Specifically, this solution effectively addresses the instability of the connecting space 201 by optimizing the structural design of the first limiting component 200. Multiple connecting ribs 210 are arranged vertically at intervals. Based on the geometric characteristics of the ends of the reinforcing cage 10, the ends are allowed to smoothly extend and adapt to limiting requirements at different heights, thus forming continuous constraint points during rotation. This design not only improves the sealing and anti-extraction capability of the connecting space 201 but also significantly enhances the overall structural load-bearing capacity. Simultaneously, both ends of each connecting rib 210 are connected to two adjacent precast main ribs 110. Relying on the rigid support of the precast main ribs 110, the limiting component is firmly integrated with the support body, preventing local loosening or failure under the force of rotation. This design, in conjunction with the support section 111 and connecting section 112 of the precast support 100, ensures that the reinforcing cage 10 is reliably fixed during rotation, ultimately guaranteeing a smooth and controllable rotation process and preventing damage caused by contact between the ends of the reinforcing cage 10 and the ground.

[0045] Through the above technical solution, the structure of the first limiting component 200 is clearly defined, and the stability of the connecting space 201 is significantly improved, thereby ensuring that the steel cage 10 maintains a stable posture during the flipping process, reducing safety risks and improving flipping efficiency.

[0046] In an embodiment of this utility model, the distance between two adjacent precast main reinforcement bars 110 is D, and 200mm≤D.

[0047] Specifically, the distance D between two adjacent precast main reinforcement bars 110 refers to the minimum interval between two adjacent precast main reinforcement bars 110 in the frame structure that provides support during the flipping process of the steel cage 10. In practical applications, this distance can be achieved by adjusting the arrangement of the precast main reinforcement bars 110, for example, by using positioning molds with fixed spacing or by precisely controlling the installation position with measuring tools. The purpose is to ensure that the end of the steel cage 10 can be smoothly embedded into the connection space 201, while avoiding jamming due to insufficient gaps.

[0048] More specifically, this technical solution optimizes the interaction mechanism between the support and the reinforcing cage 10 by setting a minimum spacing of no less than 200 mm between adjacent precast main reinforcement bars 110. In actual operation, when the end of the reinforcing cage 10 extends into the connecting space 201 formed by the connecting bars 210, the sufficient spacing effectively disperses the contact stress between the reinforcing cage 10 and the support, making the overturning torque distribution more uniform and thus reducing local frictional resistance. In addition, this design can also ensure that the reinforcing cage 10 rotates smoothly around the support section 111 to an upright position, preventing structural damage caused by end deformation due to compression or hard contact with the ground. Based on the above solution, not only is the problem of excessive compression at the end of the reinforcing cage 10 during the overturning process solved, but the stability and efficiency of the overturning process are also significantly improved, forming a complete technical system.

[0049] In an embodiment of this utility model, the connecting component 300 includes a plurality of binding wires, which are spaced apart along the extension direction of the connecting segment 112 in the connecting space 201. The end of the reinforcing cage 10 extends into the connecting space 201 and is detachably connected to the connecting segment 112 through the plurality of binding wires.

[0050] Specifically, binding wire refers to a type of flexible metal wire, which can be made of galvanized iron wire, stainless steel wire, or other wires with similar properties. The choice of this material is primarily based on its good tensile strength and corrosion resistance, ensuring reliable connection performance during the flipping process. Multiple binding wires are spaced apart along the extension direction of the connecting section 112 to distribute stress through evenly distributed connection points, avoiding connection failure caused by localized stress concentration. The detachable connection between the end of the reinforcing cage 10 and the connecting section 112 can be achieved by adjusting the binding method of the binding wire, such as using single-strand winding or double-strand crossing, to adapt to different construction needs and improve operational convenience.

[0051] More specifically, this scheme achieves a stable connection between the end of the reinforcing cage 10 and the connecting section 112 through the arrangement of multiple binding wires. The multiple binding wires are spaced apart along the extension direction of the connecting section 112, ensuring a uniform distribution of connection points in the vertical direction. This effectively balances the force when the reinforcing cage 10 rotates around the supporting section 111, preventing loosening or displacement due to excessive local stress. Furthermore, the flexibility of the binding wires allows them to adapt to shape changes at the end of the reinforcing cage 10, further enhancing the reliability of the connection. In practice, construction workers can easily connect the reinforcing cage 10 to the connecting section 112 with simple binding actions and quickly disassemble it after rotation, significantly reducing manual intervention time. This design not only simplifies the structure but also reduces manufacturing and maintenance costs, while avoiding safety hazards caused by weak connections during traditional rotation processes, thus improving overall construction efficiency and safety.

[0052] In summary, through the above technical solutions, this application effectively solves the safety risks that may be caused by the complex or unstable structure of the connecting component 300 during the flipping process, while improving the ease of operation and construction efficiency.

[0053] Please continue reading. Figure 1In an embodiment of this utility model, the second limiting component 400 includes a first layer of reinforcing bars 410, a second layer of reinforcing bars 420, and a third layer of reinforcing bars 430. The first layer of reinforcing bars 410, the second layer of reinforcing bars 420, and the third layer of reinforcing bars 430 are connected to the support section 111 in a vertical direction from bottom to top. The third layer of reinforcing bars 430 is disposed at the end of the support section 111 away from the connecting section 112. The first layer of reinforcing bars 410 and the third layer of reinforcing bars 430 both extend along the length or width direction of the reinforcing cage 10. A portion of the second layer of reinforcing bars 420 is disposed between the support section 111 and the third layer of reinforcing bars 430 to form a reinforcing section. The reinforcing section extends along the extension direction of the support section 111. Another portion of the second layer of reinforcing bars 420 is disposed at the end of the support section 111 near the connecting section 112 and extends along the length or width direction of the reinforcing cage 10.

[0054] Specifically, the first layer of reinforcing bars 410 refers to the bottommost transverse support structure, which can be implemented using threaded steel bars or plain round steel bars, primarily to provide horizontal support for the foundation. The second layer of reinforcing bars 420 refers to the intermediate layer's composite functional structure, which can be implemented using ribbed steel bars or cold-rolled ribbed steel bars, specifically designed with extensions in two different directions to simultaneously enhance support performance in both vertical and horizontal directions. The third layer of reinforcing bars 430 refers to the top distal restraint structure, which can be implemented using high-strength steel bars or prestressed steel bars, focusing on limiting the overturning range of the reinforcing cage 10. The reinforcing section refers to the portion of the second layer of reinforcing bars 420 that extends along the support section 111, which can be achieved by increasing the cross-sectional area of ​​the reinforcing bars or using a double-layer reinforcing bar arrangement, with the aim of improving the overall structural stiffness.

[0055] More specifically, this technical solution achieves comprehensive protection for the steel cage 10 during the flipping process through the collaborative design of a multi-layered steel reinforcement structure. The first layer of steel reinforcement 410 serves as the basic support layer, forming a stable upper and lower limiting system together with the third layer of steel reinforcement 430, ensuring that the steel cage 10 remains within a predetermined spatial range during the flipping process. The position design of the third layer of steel reinforcement 430 specifically considers the extreme positions when the steel cage 10 is flipped to an upright state, effectively avoiding direct contact between the bottom end face and the ground. The special structural design of the second layer of steel reinforcement 420 not only enhances the overall rigidity of the support section 111 but also provides additional limiting points in the area near the connecting section 112, forming a multi-layered protection system. This layered layout and directional extension design concept, combined with other structural features of the aforementioned auxiliary flipping device, significantly improves the stability and safety of the steel cage 10 during the flipping process, fundamentally solving the technical problem of easy damage to the ends of the steel cage 10.

[0056] In an embodiment of this utility model, the included angle between the support segment 111 and the connecting segment 112 is 90°.

[0057] Specifically, the angle between the support section 111 and the connecting section 112 refers to their angular relationship in terms of geometry, which can be achieved through precise machining or welding processes. The purpose of this design is to ensure the stability of the reinforcing cage 10 during the flipping process through strict geometric constraints and to optimize the controllability of the rotation trajectory.

[0058] More specifically, the included angle between the support section 111 and the connecting section 112 is set at 90°, fundamentally optimizing the structural geometry of the flipping device. During the initial flipping stage of the reinforcing cage 10, the support section 111 provides reliable support perpendicular to the ground, preventing swaying during initial placement. Simultaneously, the connecting section 112 remains horizontal, facilitating the stable insertion of the end of the reinforcing cage 10 into the connecting space 201, laying the foundation for subsequent flipping. During the flipping process, because the included angle is strictly limited to a right angle, the center of rotation is fixed at the end of the support section 111, allowing the reinforcing cage 10 to rotate smoothly along a predetermined trajectory with the support section 111 as its axis, effectively suppressing the risk of path deviation. When flipped to an upright position, the support section 111 naturally transitions to a horizontal position, and the connecting section 112 simultaneously turns to a vertical direction. The bottom of the reinforcing cage 10 is completely suspended, thoroughly avoiding direct contact between the end face and the ground, thereby protecting the structural integrity of the reinforcing cage 10. This angle constraint not only simplifies the operation process, but also improves the controllability of the flipping through geometric constraints, avoiding the safety risks caused by manual intervention, and ultimately achieving efficient and safe posture conversion.

[0059] In an embodiment of this utility model, the length of the support segment 111 is H, and 500mm≤H.

[0060] Specifically, the support section 111 refers to the structural part used to provide a fulcrum and prevent the end from contacting the ground during the overturning process of the reinforcing cage 10. It can be made of a metal material with sufficient strength and rigidity, such as steel or aluminum alloy profiles. The length H of the support section 111 is set to be no less than 500 mm. This parameter is selected based on the dynamic characteristics during the overturning process. The purpose is to optimize the mechanical performance of the overturning device by extending the distance between the overturning fulcrum and the bottom of the reinforcing cage 10, thereby ensuring the stability and safety of the reinforcing cage 10 during the attitude adjustment process.

[0061] More specifically, the length H of the support section 111 directly affects the movement trajectory of the rebar cage 10 during its flipping. When H is 500 mm or more, the distance between the flipping fulcrum and the bottom of the rebar cage 10 is effectively extended, ensuring that the bottom end remains at a safe height above the ground during the flipping process from lying down to standing up, avoiding direct collision with the ground. This design considers the typical size and weight distribution characteristics of the rebar cage 10, and the 500 mm threshold ensures sufficient lever arm effect, resulting in less external force required for the flipping operation and a smoother movement trajectory. Simultaneously, the selection of this length range also takes into account the overall compactness of the device, avoiding impacting the space utilization of the construction site due to an excessively long support section 111. Combined with other structural features of the aforementioned auxiliary flipping device, the reasonable length of the support section 111 not only eliminates the risk of structural damage but also improves operational controllability and reduces reliance on manual intervention, thereby achieving more efficient and safer rebar cage 10 posture conversion in engineering practice.

[0062] In an embodiment of this utility model, the length of the connecting segment 112 is L, where 450mm≤L≤512mm.

[0063] Specifically, the connecting segment 112 is a key structural component used to provide the connection point at the end of the reinforcing cage 10. In practical applications, the length L of the connecting segment 112 is precisely limited to ensure stability and safety during the flipping process. Its specific dimensions can be determined using engineering mechanics calculations and practical verification, aiming to balance the needs of the connection space 201 with the stability of the overall structure. The lower limit of 450 mm ensures that the connection space 201 can fully accommodate the end of the reinforcing cage 10, enabling the connecting assembly 300 to reliably fix the reinforcing cage 10 and preventing loosening or operational obstruction due to insufficient length. The upper limit of 512 mm strictly controls the extension of the connecting segment 112, suppressing excessive swaying and torque amplification caused by the lever effect during flipping, thereby significantly reducing the probability of the end of the reinforcing cage 10 colliding with the ground.

[0064] More specifically, the above technical solution effectively solves various problems that may arise during the flipping process by reasonably setting the length range of the connecting section 112. During the flipping process, the angle between the supporting section 111 and the connecting section 112 is 90°. This design allows the connecting section 112 to provide sufficient connection space 201 while avoiding structural instability due to excessive length. In addition, the length range of the connecting section 112, combined with the overall structure of the prefabricated support 100, ensures that the bottom end face of the rebar cage 10 does not directly contact the ground when flipped to the upright position, thereby protecting the structural integrity of the rebar cage 10 and improving construction reliability. At the same time, this length range also comprehensively considers the mechanical characteristics of the rebar cage 10 during flipping, making the flipping action more stable and controllable, significantly improving flipping efficiency and construction safety.

[0065] In summary, the above technical solutions not only solved the technical problems caused by the improper length of the connecting section 112, but also further optimized the overall performance of the steel cage 10 turning device, providing a more efficient and safer solution for engineering construction.

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.
