Description

Technical Field

[0001] This application relates to the field of steel cage fabrication technology, and in particular to an automated steel cage fabrication jig. Background Technology

[0002] A reinforcing cage is a cage-like structure made of welded or tied reinforcing bars. It is widely used in civil engineering, especially in reinforcing concrete components such as bridges, tunnels, high-rise buildings, bored piles, and columns. The main function of a reinforcing cage is to improve the load-bearing capacity and seismic performance of concrete structures, ensuring the safety and stability of the structure.

[0003] In foundation engineering, the reinforcing cage is a key component of bored piles, and its fabrication quality plays a crucial role in the stability and strength of the pile foundation. Traditional reinforcing cage fabrication processes are typically time-consuming, labor-intensive, and prone to errors. During manual fabrication, the main reinforcing bars must be evenly distributed in a circular structure along the circumference, leaving them suspended. Simultaneously, stirrups must be accurately installed on the longitudinal main reinforcing bars. Due to the length and suspended nature of the main reinforcing bars, they are highly susceptible to tilting or falling under their own weight during operation. Therefore, it is currently necessary to first tie the main reinforcing bars to the stirrups to ensure suspension stability. The stirrups, also requiring multiple circumferentially arranged stirrups and fixed at intervals with the main reinforcing bars, necessitate mutual support and connection between the main reinforcing bars and stirrups, which presents significant challenges during manual operation. Furthermore, the fabrication and transportation of large reinforcing cages are particularly difficult, especially when dealing with pile foundations of varying specifications, making the process even more complex. Therefore, there is an urgent need for an automated reinforcing cage fabrication jig device that can improve production efficiency, ensure accuracy, and facilitate operation and transportation. Summary of the Invention

[0004] To address the aforementioned problems, this application aims to provide an automated rebar cage fabrication jig that can position and arrange the main reinforcement bars and stirrups, solving the operational difficulties currently required by pre-tying both, thereby effectively improving the fabrication quality and efficiency of the rebar cage.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: an automated steel cage fabrication jig, wherein the steel cage has multiple main bars evenly distributed along the circumferential spacing, and multiple stirrups are ringed around the main bars along the circumferential spacing, characterized in that: the jig includes an arrangement mechanism that distributes several main bars at fixed intervals and forms a steel cage as a whole, and a drive mechanism connected to the arrangement mechanism and driving the arrangement mechanism and the steel cage to rotate.

[0006] Preferably, the arrangement mechanism includes support discs spaced axially, with arrangement holes for main ribs passing through evenly spaced along the circumference on each support disc; an end disc is provided on the outer side of each support disc, and a positioning blind hole corresponding to the arrangement hole is provided on the inner side of each end disc; and each support disc and end disc can be close to or far apart.

[0007] Preferably, the supporting disc includes an arc-shaped outer disc with an upper and lower half structure that can be detached and locked, and a plurality of splicing discs located on the inner side of the arc-shaped outer disc and forming a ring structure along the circumference. A shaping ring is provided on the inner side of the splicing disc to drive each splicing disc to abut against the arc-shaped outer disc, and arc-shaped half-holes forming the arrangement holes are provided on the inner wall of the arc-shaped outer disc and the outer wall of the splicing disc.

[0008] Preferably, each of the supporting discs is provided with a locking gear at its bottom that meshes with its gear, and each of the end discs is provided with a rotating bracket on its outer side wall.

[0009] The beneficial effects of this application are as follows: The fabrication jig uses an arrangement mechanism to prioritize the spacing of multiple main reinforcing bars arranged circumferentially, thereby forming a reinforcing cage frame. Based on this fixed shape, circular stirrups can be easily fitted onto the main reinforcing bars, effectively solving the operational difficulty of currently suspending multiple main reinforcing bars circumferentially. The drive mechanism is used to rotate the unwelded reinforcing cage after the stirrups are fitted onto the fixed main reinforcing bars, thereby welding the stirrups to each main reinforcing bar circumferentially, thus improving welding efficiency.

[0017] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] See attached document Figures 1-6 The invention discloses an automated rebar cage fabrication jig. The rebar cage has multiple main reinforcing bars evenly spaced circumferentially, and multiple circular stirrups are circumferentially spaced around the main reinforcing bars. The stirrups are fitted onto several longitudinal main reinforcing bars and welded together to form a complete rebar cage structure. To address the current problem of difficulty in relative positioning of multiple main reinforcing bars and stirrups before welding and fixing, which causes operational difficulties, this application provides a rebar cage fabrication jig. Figure 3 As shown, the frame includes an arrangement mechanism that distributes several main reinforcing bars at fixed intervals to form a reinforcing cage, and a drive mechanism connected to the arrangement mechanism and driving the arrangement mechanism and the reinforcing cage to rotate. The arrangement mechanism prioritizes the fixed-interval arrangement of multiple main reinforcing bars at circumferential spacing, thereby forming a reinforcing cage frame. Based on this frame, circular stirrups can be easily fitted onto the main reinforcing bars, effectively solving the current operational difficulty of suspending multiple main reinforcing bars circumferentially.

[0019] The drive mechanism is used to place the stirrups onto the shaped main bars and then rotate the unwelded steel cage as a whole, thereby welding the stirrups to each main bar along the circumference, thus improving the efficiency of the welding operation.

[0020] Specifically, such as Figure 3-4 As shown, the arrangement mechanism includes support disks 1 spaced axially, and each support disk 1 has arrangement holes 1a with main ribs passing through it at even intervals along the circumference; as shown Figure 5 As shown, by sequentially passing multiple main reinforcing bars through the horizontally corresponding arrangement holes 1a on each supporting disc 1, a reinforcing cage structure can be formed, achieving support and fixed-distance arrangement of the multiple main reinforcing bars. And as... Figure 5 As shown, when the main reinforcing bars are inserted from the arrangement hole 1a of the left support disc 1 towards the right support disc 1, stirrups can be installed on the main reinforcing bars between adjacent support discs 1, such as... Figure 5 The state shown.

[0021] To address the issue of misalignment and unevenness at the ends of multiple main reinforcing bars after they pass through the arrangement hole 1a, such as... Figure 3 , 6As shown, each supporting disc 1 has an end disc 2 on its axial outer side, and each end disc 2 has a positioning blind hole 2a corresponding to the arrangement hole 1a on its inner side. After the supporting discs 1 are spaced apart to arrange, support, and shape several main reinforcement bars, the two ends of each main reinforcement bar are inserted and abutted through the positioning blind holes 2 of the end discs 2 on both sides, thereby adjusting the ends of each main reinforcement bar to be in a flush state and improving the dimensional accuracy of the reinforcement cage fabrication. When the ends of the main reinforcement bars are fitted into the positioning blind holes 2a, it is preferable to fit stirrups on the main reinforcement bars between the supporting discs 1 and the end discs 2.

[0022] To facilitate the insertion of the main reinforcing bars through the arrangement holes 1a of the supporting discs and their connection to the positioning blind holes 2a, preferably, each of the supporting discs 1 and the end discs 2 can be close to or far apart. Since the main reinforcing bars are relatively long and prone to bending when suspended, when passing the main reinforcing bars through the arrangement holes 1a of adjacent supporting discs 1, the supporting discs 1 can be moved closer together, making the arrangement holes 1a on adjacent supporting discs similar. This allows for the rapid and linear simultaneous insertion of the main reinforcing bars. A gap is left between adjacent supporting discs 1 to facilitate the installation of multiple stirrups, which can be installed tightly. After installing sufficient stirrups between adjacent supporting discs 1, the end of the main reinforcing bar is inserted into the arrangement hole 1a of the supporting disc 1 on the other side. Simultaneously, the supporting discs 1 are moved away from each other, and the spacing between adjacent stirrups is adjusted. Then, after installing a sufficient number of stirrups on the main reinforcement between the supporting disc 1 and the end disc 2, the end disc is moved so that the end of the main reinforcement is inserted into the positioning blind hole 2a, thus realizing the arrangement and shaping of the main reinforcement and stirrups. Then, the welding operation at the joint of the main reinforcement and stirrups can be carried out.

[0023] After the main reinforcement bars and stirrups are welded together, a steel cage is formed into an integral structure. To facilitate the disassembly of the steel cage and supporting disc, such as... Figure 4 As shown, the supporting disc 1 includes an arc-shaped outer disc 11 with an upper and lower half structure that can be detached and locked, and a plurality of splicing discs 12 located inside the arc-shaped outer disc 11 and forming a circular structure along the circumference. A shaping ring 13 is provided inside the splicing disc 12 to drive each splicing disc 12 to abut against the arc-shaped outer disc 11. Arc-shaped half-holes 1a1 forming the arrangement holes 1a are provided on both the inner wall of the arc-shaped outer disc 11 and the outer wall of the splicing discs 12. The supporting disc 1 is assembled before the main reinforcement is installed, as follows: Figure 4As shown, firstly, the upper and lower half-structured arc-shaped outer disks 11 are assembled into an integral structure (preferably, each arc-shaped outer disk 11 has an assembly hole 11a, and the upper and lower arc-shaped outer disks 11 can be connected into a circular integral structure by using a rectangular bracket 5 inserted through the assembly hole). Then, multiple splicing disks 12 are assembled and spliced ​​on the shaping ring 13 (preferably, each splicing disk 12 is connected to the shaping ring 13 by bolts). Then, they are inserted into the arc-shaped outer disk 11 from the side opposite to the rectangular bracket. The arc-shaped half-holes 1a1 on the splicing disk 12 and the arc-shaped half-holes 1a1 on the arc-shaped outer disk 11 correspond to form the arrangement holes 1a, which can realize the assembly of the supporting disk. Then, the main ribs can be inserted in the arrangement holes 1a.

[0024] After the main reinforcement bars and stirrups are welded together, the upper arc-shaped outer plate 11 and multiple splicing plates 12 are disassembled. The welded steel cage can then be temporarily placed on the lower arc-shaped outer plate 11. When in use, the steel cage can be directly hoisted and detached from the lower arc-shaped outer plate 11.

[0025] To fix the angle when rotating the main reinforcement and stirrups circumferentially, such as... Figure 3 , 6 As shown, each of the supporting discs 1 has a locking gear 3 at its bottom that meshes with its gear, and each of the end discs 2 has a rotating bracket 4 on its outer side wall. The locking gears 3 are symmetrically arranged on the left and right sides, and achieve gear meshing by supporting the supporting discs 1. One side of the locking gear 3 can preferably be driven by a motor, and locking can be achieved by rotating the locking gear 3, which facilitates the circumferentially stable welding operation of the main reinforcement and stirrups. When the supporting disc 1 rotates, the outer end disc 2 rotates synchronously on the rotating bracket 4.

[0026] Both the bottom of the rotating bracket 4 and the bottom of the locking gear 3 are equipped with rollers 6 that allow the supporting disc 1 and the end face disc 2 to move closer or further apart.

[0027] To facilitate the rapid insertion and connection of the main reinforcement bars in the arrangement hole 1a and the positioning blind hole 2a, it is preferable that the ports of the arrangement hole 1a and the positioning blind hole 2a are both designed with tapered openings, and the larger ports facilitate the rapid insertion of the main reinforcement bars.

[0028] The principle of this application is as follows: When making the steel cage, the upper and lower half-structured arc-shaped outer plate 11 is first assembled into an integral structure by a rectangular bracket. Then, multiple splicing plates 12 are assembled and spliced ​​on the shaping ring 13. Then, they are embedded into the arc-shaped outer plate 11 from the side opposite to the rectangular bracket. The arc-shaped half-holes 1a1 on the splicing plate 12 and the arc-shaped half-holes 1a1 on the arc-shaped outer plate 11 correspond to form the arrangement holes 1a, which can realize the assembly of the support disc. Then, the support disc 1 is placed on the locking gear 3 and engaged.

[0029] Next, the main reinforcement bars are inserted. Multiple main reinforcement bars are passed sequentially through the horizontally corresponding arrangement holes 1a on each supporting disc 1, and stirrups are simultaneously fitted. Then, the ends of the main reinforcement bars are inserted into the positioning blind holes 2a of the end face disc 2 to achieve flush alignment of the ends of the main reinforcement bars. Afterward, driven by the locking gear, the joints of the main reinforcement bars and stirrups can be welded circumferentially. After welding, the end face discs 2 on both sides are moved to separate from the ends of the main reinforcement bars, and the upper arc-shaped outer disc 11 is disassembled from the splicing disc. The formed steel cage is temporarily placed on the lower arc-shaped outer disc 11, and the steel cage can be directly hoisted during use.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
