Description

Technical Field

[0001] This utility model belongs to the field of building engineering equipment technology, and in particular relates to an auxiliary tooling for modular assembly of steel cages. Background Technology

[0002] As an important load-bearing component inside a structure, the reinforcing cage plays a crucial role in engineering construction. It not only provides the necessary skeletal support for the concrete structure, ensuring that the overall load-bearing performance meets the design requirements, but also plays a role in positioning, stabilizing and standardizing construction operations during the construction process. This improves the overall forming quality and construction efficiency of the structure, reduces the risk of deformation and cracking during construction, and lays a solid foundation for the safety, durability and later service performance of the structure.

[0003] In existing technologies, cross-shaped steel cages are typically composed of horizontal and vertical bars that are perpendicular to each other. They are tied and fixed manually at the intersections, and their forming and positioning mainly rely on manual operation by construction workers on site. This traditional construction method has several drawbacks and shortcomings: First, it is inefficient, as the steel cage forming process is cumbersome and time-consuming, making it difficult to meet the needs of large-scale, rapid construction. Second, construction accuracy is difficult to guarantee, as manual binding is greatly affected by the skill level of construction workers and on-site environmental factors, easily leading to steel cage positioning deviations and dimensional errors, which in turn affect subsequent concrete pouring and the overall structural quality. Third, it is labor-intensive, requiring construction workers to bend over, lift, and bind steel cages for extended periods, easily causing fatigue, reducing work quality, and posing a significant risk of occupational injury. In addition, the consistency and standardization of construction quality are low, with significant differences in operation among different construction workers, making it difficult to control the consistency of finished steel cages. At the same time, it is significantly limited by on-site conditions such as weather and site conditions, further increasing the difficulty and error rate of construction in harsh environments. Finally, since on-site binding is mostly done manually, there are hidden dangers such as insecure binding and loose joints, which may lead to deformation or damage during transportation, hoisting, or pouring, seriously affecting the safety and durability of the project.

[0004] To address the problems of low efficiency, poor positioning accuracy, and unstable assembly quality in the existing technology of manual assembly of steel cages on site, this utility model provides an auxiliary tooling for modular assembly of steel cages.

[0005] This utility model is implemented as follows: a modular assembly auxiliary tooling for steel cages, characterized in that it includes a lower formwork frame, an upper formwork frame, a positioning frame, and a guide sleeve; the lower formwork frame is positioned by the foundation vertical reinforcement and forms a vertical guiding structure for the upper formwork frame; the positioning frame is installed on the upper formwork frame, and the positioning frame has a limiting part that allows the pre-installed horizontal reinforcement and the pre-installed vertical reinforcement to form a cross-grid arrangement; the guide sleeve is fixed to the positioning frame, and the lower part of the guide sleeve forms a guide cone opening that vertically aligns the pre-installed vertical reinforcement with the foundation vertical reinforcement.

[0006] In the above technical solution, preferably, a primary guide is formed between the upper mold frame and the lower mold frame to align the pre-installed vertical ribs with the foundation vertical ribs vertically, and a secondary guide is formed at the lower part of the guide sleeve to align the pre-installed vertical ribs with the foundation vertical ribs vertically.

[0007] In the above technical solution, preferably, the limiting part includes a horizontal limiting groove for the pre-installed horizontal rib to be horizontally arranged, a vertical limiting groove for the pre-installed vertical rib to be vertically arranged, and a clamping component for clamping the pre-installed horizontal rib and the pre-installed vertical rib together.

[0009] In the above technical solution, preferably, the lateral limiting groove and the vertical limiting groove are arc-shaped grooves.

[0010] In the above technical solution, preferably, the clamping component is a clamping plate connected to the positioning frame by fasteners, and the surface cross grid formed by the pre-installed horizontal ribs and pre-installed vertical ribs is clamped between the positioning frame and the clamping plate.

[0011] In the above technical solution, preferably, the upper part of the guide sleeve forms the vertical limiting groove located below.

[0012] In the above technical solution, preferably, the positioning frame is installed on the upper mold frame in a longitudinal adjustment manner, and the longitudinal adjustment direction of the positioning frame is perpendicular to the cross grid surface formed by the pre-installed horizontal ribs and pre-installed vertical ribs.

[0013] In the above technical solution, preferably, a quick-twisting machine is installed on the upper part of the upper mold frame, and the quick-twisting machine is provided with a rotating sleeve located at the upper end of the pre-installed vertical rib.

[0016] First, by pre-installing horizontal and vertical reinforcing bars on the upper formwork, standardized cross-shaped grid units are pre-formed, achieving pre-forming and standardization of the reinforcing cage, significantly improving construction efficiency and shortening the overall construction period. Second, the limiting parts on the positioning frame can precisely define the positional relationship of the horizontal and vertical reinforcing bars, ensuring a uniform and regular grid arrangement, thereby improving the forming accuracy of the reinforcing cage and avoiding dimensional deviations and inaccurate positioning caused by human error. Simultaneously, the guide cone formed at the bottom of the guide sleeve can assist in the vertical alignment of the pre-installed vertical reinforcing bars with the foundation vertical reinforcing bars, further ensuring the overall installation accuracy and verticality of the reinforcing cage and improving structural stability.

[0017] Furthermore, the standardized pre-assembly of each reinforcing steel component using specialized positioning devices significantly improves the consistency and standardization of the reinforcing cage formation, ensuring stable and controllable construction quality and reducing structural hazards caused by construction variations. This device also reduces reliance on highly skilled labor on the construction site, minimizing quality fluctuations due to varying skill levels and enhancing the overall controllability of project quality management. Simultaneously, the modular assembly method significantly reduces the labor intensity of construction workers, lowers safety risks associated with high-altitude operations and repeated binding processes, and improves construction safety. Finally, this invention can adapt to complex and changing construction environments, reducing the impact of weather, site limitations, and other factors on construction progress and quality, demonstrating significant potential for widespread application and economic benefits.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0024] To address the problems of low efficiency, poor positioning accuracy, and unstable assembly quality in existing manual rebar cage assembly techniques, this utility model provides an auxiliary tooling for modular rebar cage assembly. To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings:

[0025] Please see Figures 1-4 A modular assembly auxiliary tooling for steel cages includes a lower formwork frame 1, an upper formwork frame 2, a positioning frame 3, and a guide sleeve 4.

[0026] The lower mold frame is positioned by the foundation vertical ribs 5 and forms a vertical guide structure for the upper mold frame. Specifically, in this embodiment, the left and right outer sides of the lower mold frame and the left and right inner sides of the upper mold frame form a wedge-shaped vertical guide structure. In this embodiment, the lower mold frame is initially positioned by the foundation vertical ribs and simultaneously cooperates with the upper mold frame to form a vertical guide structure, thereby guiding the upper mold frame during hoisting and positioning. Specifically, the left and right outer sides of the lower mold frame are inclined surfaces that gradually converge upwards, while the left and right inner sides of the upper mold frame are inclined surfaces that gradually expand downwards in conjunction with the outer sides of the lower mold frame. The two sets of inclined surfaces together form a wedge-shaped vertical guide structure. When the upper mold frame falls from above onto the lower mold frame, guided by the inclined surfaces, the upper mold frame can gradually center and align horizontally while falling stably vertically, avoiding lateral swaying or misalignment. Through this wedge-shaped vertical guide structure, the upper formwork can automatically align with the lower formwork without much manual intervention, improving the vertical alignment accuracy of the pre-installed horizontal and vertical reinforcement units with the foundation vertical reinforcement, effectively reducing installation errors, and improving construction efficiency and assembly quality.

[0027] In this embodiment, both the upper and lower mold frames are formed by welding profiles, providing good overall rigidity and ease of manufacturing. Specifically, the upper mold frame has a portal frame structure with a central opening between its two side columns. This opening is used to install the positioning frame and provides space for the arrangement and operation of the cross-shaped grid units formed by the pre-installed horizontal and vertical ribs. A dust cover 1-1 is installed on the upper part of the lower mold frame. The dust cover is detachably connected to the lower mold frame by fasteners (such as bolts and nuts), facilitating quick installation and disassembly according to construction needs.

[0028] The lower part of the dust cover is equipped with several positioning plugs, each corresponding to the position of a threaded sleeve 6 fitted at the top of a foundation vertical rib. The shape and size of the positioning plugs match the diameter of the threaded sleeves, enabling initial alignment and stability upon insertion. By inserting the positioning plugs on the dust cover into the threaded sleeves at the top of the foundation vertical ribs, the lower mold frame can achieve initial and precise positioning with the foundation vertical ribs during hoisting and placement, ensuring the accuracy and stability of the overall position of the lower mold frame. After the lower mold frame is fully in place, before formally connecting the pre-installed vertical ribs with the foundation vertical ribs, the dust cover is removed to make room for subsequent connection.

[0029] The dust cover plays a crucial role: firstly, during construction, it effectively seals the threaded sleeves at the top of the foundation vertical reinforcement bars, preventing common construction site contaminants such as mud, dust, and impurities from entering the threaded sleeves. This avoids problems like thread blockage and connection difficulties during subsequent connections, ensuring smooth threaded connections and connection quality. Secondly, the dust cover also serves as an auxiliary positioning tool during installation, providing precise guidance for the hoisting and positioning of the lower formwork, improving construction efficiency and accuracy. Through the above structural design, this invention not only achieves efficient and precise positioning during the modular assembly of the rebar cage but also effectively mitigates the potential impact of the construction environment on connection quality, further enhancing the overall reliability of the construction and the quality of the finished product.

[0030] The positioning frame is installed on the upper mold frame, and the positioning frame is provided with limiting parts that allow the pre-installed horizontal ribs 7 and pre-installed vertical ribs 8 to form a cross-grid arrangement. Specifically, in this embodiment, the positioning frame is installed on the upper mold frame in a longitudinally adjustable manner, and the longitudinal adjustment direction of the positioning frame is perpendicular to the cross-grid surface formed by the pre-installed horizontal and vertical ribs. In this specific embodiment, "longitudinal" refers to the direction perpendicular to the plane containing the horizontal and vertical directions of the pre-installed horizontal and vertical ribs. The positioning frame is formed by two vertical frames and three horizontal frames fixedly connected, with limiting parts evenly spaced on the two vertical frames and three horizontal frames.

[0031] In this embodiment, the main function of the positioning frame is to ensure that the pre-installed horizontal and vertical reinforcing bars form a precise cross-grid arrangement through the limiting part. Specifically, the positioning frame is installed on the upper formwork frame by longitudinal adjustment. This longitudinal adjustment method ensures that the single-layer cross-grid structure formed by the pre-installed horizontal and vertical reinforcing bars, as a basic module unit, can be sequentially connected and installed with the basic vertical reinforcing bars from the inside out, ultimately forming a reinforcing cage connected to the basic vertical reinforcing bars. The cross-grid plane formed by the pre-installed horizontal and vertical reinforcing bars is a vertical plane; therefore, the longitudinal adjustment direction is a horizontal straight line perpendicular to this vertical plane. Through longitudinal adjustment, the positioning frame can precisely adjust the arrangement position of the pre-installed horizontal and vertical reinforcing bars, ensuring that they are connected to the basic vertical reinforcing bars in sequence and accurately, thereby ensuring a stable and precise assembly process for the reinforcing cage. This longitudinal adjustment design allows each reinforcing cage module unit to be sequentially connected to the basic vertical reinforcing bars to form the overall structure of the reinforcing cage, while avoiding errors that may occur during on-site manual operation.

[0032] In this embodiment, the upper end of the positioning frame is mounted on the upper mold frame via a longitudinal slide rail located on the upper part of the upper mold frame. A longitudinal lead screw 9 is installed between the positioning frame and the upper mold frame. The inner end of the longitudinal lead screw forms a rotating pair with the positioning frame. The longitudinal lead screw is connected to the side of the upper mold frame via a threaded sleeve. Rotating the longitudinal lead screw can adjust the longitudinal position of the positioning frame. The longitudinal lead screw is rotated manually or electrically. When the lead screw rotates, the thread inside the lead screw engages with the thread in the threaded sleeve, causing the rotation of the lead screw to drive the positioning frame to move back and forth along the longitudinal slide rail, thereby realizing the adjustment of the longitudinal position of the positioning frame. The accuracy of this adjustment process can be controlled by the pitch of the lead screw. A smaller pitch can provide higher adjustment accuracy, ensuring that each adjustment can achieve millimeter-level or even smaller precise control. Specifically, the upper end of the upper mold frame forms a lifting platform. The lifting platform is provided with a longitudinal slide rail. The upper ends of two vertical frames pass through the longitudinal slide rail, and the upper ends are provided with a hanging end for the vertical frames to be installed on the lifting platform.

[0033] The longitudinal spacing of the positioning frame should be consistent with the calibrated distance between two adjacent cross-grid frames of the reinforcing cage during each adjustment. Specifically, the reinforcing cage consists of multiple cross-grid units formed by the intersection of pre-installed horizontal and vertical reinforcing bars. The dimensions of each cross-grid unit are pre-calibrated to ensure the overall structural stability and load-bearing capacity of the reinforcing cage. Therefore, the adjustment spacing of the positioning frame must precisely match the calibrated distance between two adjacent cross-grid frames. Each time the longitudinal screw is rotated and the positioning frame is adjusted, the screw pitch determines the distance the positioning frame moves along the longitudinal slide. The distance of movement during adjustment needs to be consistent with the standard dimensions of the reinforcing cage's cross-grid frames. This adjustment function ensures that each adjustment of the positioning frame during the reinforcing cage assembly process ensures that the pre-installed horizontal and vertical reinforcing bars are arranged according to the predetermined calibrated distance, thus making the entire reinforcing cage structure more standardized and stable.

[0034] The limiting part includes a horizontal limiting groove 3-1 that horizontally limits the pre-installed horizontal reinforcement, a vertical limiting groove 3-2 that vertically limits the pre-installed vertical reinforcement, and a clamping component 3-3 that clamps the pre-installed horizontal and vertical reinforcements together. Specifically, two horizontal limiting grooves symmetrically arranged on the left and right form a set of horizontal positioning components for positioning one pre-installed horizontal reinforcement; two vertical limiting grooves symmetrically arranged vertically form a set of vertical positioning components for positioning one pre-installed vertical reinforcement; the positioning frame has N sets of horizontal positioning components evenly spaced vertically and N sets of vertical positioning components spaced horizontally. The horizontal and vertical limiting grooves are arc-shaped grooves. The clamping component is a clamping plate connected to the positioning frame by fasteners, and the cross-shaped grid formed by the pre-installed horizontal and vertical reinforcements is clamped between the positioning frame and the clamping plate. By setting the horizontal limiting grooves, vertical limiting grooves, and clamping components, the pre-installed horizontal and vertical reinforcements can be accurately limited and effectively clamped, realizing the standardized and stable arrangement of the reinforcement. The symmetrical horizontal limiting grooves and symmetrical vertical limiting grooves provide bidirectional limiting for each horizontal and vertical reinforcing bar, ensuring their spatial accuracy and preventing positional deviation or skew, thus improving the consistency and standardization of the cross-grid formation. The arc-shaped grooves naturally fit the circular cross-section of the reinforcing bars, further enhancing the stability and positioning accuracy of the limiting. The added clamping components firmly fix the pre-assembled reinforcing bars through clamping, preventing them from loosening or slipping during hoisting and improving the structural strength of the overall pre-assembled unit. This facilitates overall handling and rapid connection, effectively improving construction efficiency, forming accuracy, and safety.

[0035] The guide sleeve is fixed to the positioning frame, and the lower part of the guide sleeve forms a guide cone opening to align the pre-installed vertical rib with the foundation vertical rib vertically. The upper part of the guide sleeve forms the vertical limiting groove located below.

[0036] This modular assembly auxiliary tooling for the rebar cage can be installed using tower cranes and other types of mechanical equipment. During the hoisting and positioning process, the upper formwork and the lower formwork form a primary guide to align the pre-installed vertical bars with the foundation vertical bars. The lower part of the guide sleeve forms a secondary guide to further align the pre-installed vertical bars with the foundation vertical bars. The primary guide between the upper and lower formwork and the secondary guide at the bottom of the guide sleeve further improve the guiding accuracy and stability of the pre-installed vertical bars and foundation vertical bars during vertical connection. The primary guide provides preliminary coarse positioning, ensuring that the pre-installed bars are roughly aligned with the foundation bars, avoiding significant deviations during hoisting. The secondary guide achieves fine correction through the guide cone, ensuring precise alignment of the vertical bars, reducing reliance on manual adjustments, lowering installation errors, improving assembly efficiency and finished product quality, and effectively preventing misalignment, collision, and deformation of the vertical bars, further enhancing construction reliability and overall structural performance.

[0037] The upper part of the upper mold frame is equipped with a quick-twisting machine 10. The quick-twisting machine is provided with a rotating sleeve located at the upper end of the pre-installed vertical rib. The rotating sleeve is connected to the upper end of the pre-installed vertical rib by a thread and drives the pre-installed vertical rib to rotate. The lower mold frame is equipped with a wire binding machine 11 through a three-dimensional linear module.

[0038] The main function of the quick-tightening machine is to quickly connect and tighten reinforcing bars through automatic rotation. For example... Figure 5 Specifically, the quick-twisting machine includes a rotating sleeve 10-1 and a driving device 10-2. The rotating sleeve is a component that is threadedly connected to the upper end of the pre-installed vertical rib. The rotating sleeve has a precision thread structure inside, which can tightly fit with the threaded part of the upper end of the pre-installed vertical rib. The driving device of the quick-twisting machine drives the rotating sleeve to rotate through a motor. When rotating, the rotating sleeve will drive the upper end of the pre-installed vertical rib to rotate together, thereby realizing the threaded connection between the lower end of the pre-installed vertical rib and the upper end of the foundation vertical rib. In this embodiment, specifically, a gantry frame is installed on the hoisting platform of the upper mold frame. The quick-twisting machine is installed on the gantry frame through a vertical hydraulic cylinder 12. The rotating sleeve of the quick-twisting machine is an axially vertical rotating component installed on the quick-twisting machine housing 10-3 through bearings. Several rotating sleeves are distributed at intervals along the upper edge of the surface cross grid, and the interval size between the rotating sleeves is consistent with the interval size of the pre-installed vertical ribs. The driving device includes a motor and a horizontally arranged drive shaft driven by the motor. The drive shaft is installed in the quick-twisting machine housing, and the drive shaft and the rotating sleeve are driven by gear meshing. The gantry frame's position on the lifting platform is longitudinally adjustable, ensuring that the rotating sleeve of the quick-tightening machine aligns with the upper end of the pre-installed vertical ribs. The adjustable installation of the gantry frame can be achieved via a longitudinal slide rail with a position locking function, or via longitudinal threaded holes on the lifting platform. After the depth of the cross-shaped grid is determined, the gantry frame's position is fixed accordingly. The vertical hydraulic cylinder controls the quick-tightening machine's housing to move downwards, aligning the rotating sleeve with the upper end of each pre-installed vertical rib. After the lower end of the pre-installed vertical rib is aligned with the foundation vertical rib, the rotating sleeve of the quick-tightening machine applies a twisting torque to the pre-installed vertical rib.

[0039] The wire binding machine is an existing, compatible automated binding device, installed via a three-dimensional linear module. The wire binding machine uses the three-dimensional linear module to drive and bind and fix the rebar joints. Specifically, the wire binding machine is equipped with an automatic wire feeding device and a rotating binding device, which automatically feeds the rebar wire (usually iron wire) at the rebar joint to the required position and wraps it around the joint using the rotating device, thus completing the binding. The three-dimensional linear module provides the wire binding machine with a precise three-dimensional motion trajectory, enabling it to maintain precise position control throughout the binding process and ensuring that each connection point is fixed. For example, the three-dimensional linear module uses a HIWIN three-axis module system (such as KK60-MX080-1000A, paired with an ECMA-C20401SS servo motor and an ASD-B2-0421-B servo driver), controlled by a DVP-SV series PLC, to achieve precise movement along the X / Y / Z axes. The wire binding machine consists of an automatic wire feeding device and a rotary binding device. The wire feeding device is driven by an Oriental Motor PKP246D28A2 stepper motor, which, combined with a customized wire feeding guide mechanism, accurately delivers the wire to the rebar intersection point. The rotary binding device uses a MABUCHI RS-775VC high-torque motor to drive the rotating head, simulating the structure of the MAX RB441T automatic binding gun, to complete the wire winding and tightening process. The entire system is uniformly coordinated and controlled by a PLC and equipped with a Delta DOP-107BV touch screen for parameter setting and path management, enabling high-precision, automated, and rapid binding of rebar cage intersections, significantly improving work efficiency and consistency.

[0040] The aforementioned quick-twisting machine and wire-binding machine are auxiliary automated assemblies of this modular assembly device, designed to improve the device's automation level. It should be noted that, even without the quick-twisting machine and wire-binding machine, this device has pre-assembly and guiding positioning functions; the twisting and wire-binding of the pre-assembled vertical ribs can be done manually, depending on the specific usage conditions.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
