Technical Field
[0001] This utility model relates to the field of steel bar processing technology, specifically a workbench for tying steel bars. Background Technology
[0002] In existing precast wall panel construction processes, the reinforcement cage is typically tied on a scaffold, and then hoisted into the casting mold for concrete pouring. This construction method has significant drawbacks. First, the reinforcement cage is susceptible to deformation under external forces during hoisting, which affects its structural strength and stability, thus negatively impacting the quality of the precast concrete wall panel. Second, separating the reinforcement tying and pouring operations increases construction steps and time costs, reducing construction efficiency.
[0003] In conclusion, traditional precast wall panel construction methods require new equipment to improve construction processes, increase efficiency and quality, and reduce costs in areas such as rebar tying and pouring. Utility Model Content
[0004] The purpose of this utility model is to provide a rebar tying workbench that enables rebar tying and concrete pouring to be carried out on the same workbench, reducing the impact of hoisting on the rebar, facilitating the removal of pouring molds, improving construction efficiency and quality, reducing costs, and thus solving the technical problems in the background art.

[0006] The working platform is fixed on the ground; the injection mold is detachably fixed on the upper surface of the working platform; the injection mold includes two symmetrically arranged transverse baffles and two symmetrically arranged longitudinal baffles; the two longitudinal baffles and the two transverse baffles together with the upper surface of the working platform form a rectangular groove structure.
[0007] The magnetic suction device is mounted on the working platform, and its shape matches the inner wall of the pre-embedded junction box.
[0008] Furthermore, it also includes a push-pull device; the push-pull device has multiple components that are respectively connected to the transverse baffle or the longitudinal baffle, and the push-pull device drives the transverse baffle and the longitudinal baffle to move.
[0009] Furthermore, the push-pull device includes a main support frame, a guide slide, a slide column, a push plate, a transmission rod, and a handwheel;
[0010] The main support is fixed on the working platform; two guide slides are opened on the main support along the pushing and pulling direction of the push-pull device, and a sliding column is slidably connected in the guide slide; one end of the sliding column is connected to the transverse baffle or longitudinal baffle of the injection mold, and the other end is connected to the push plate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] To achieve the above objectives, this utility model provides the following technical solution, such as... Figure 1-5 As shown, a workbench for tying reinforcing bars includes: a work platform 1, a pouring mold, and a magnetic suction device 4;
[0030] The working platform 1 is made of metal and is fixed to the ground. As a supporting component, the working platform 1 bears the pouring mold, steel bars, concrete and various loads generated during the construction process.
[0031] The pouring mold is detachably fixed to the upper surface of the working platform 1; the pouring mold includes two symmetrically arranged transverse baffles 2 and two symmetrically arranged longitudinal baffles 3; the two longitudinal baffles 3 and the two transverse baffles 2 together with the upper surface of the working platform 1 form a rectangular trough structure; the longitudinal baffles 3 and the transverse baffles 2 together form the forming space of the precast concrete component, which prevents the concrete from flowing to both sides during the concrete pouring process, ensuring that the concrete is formed within the area of the trough structure to form a precast wall panel of specified size and shape.
[0032] The magnetic suction device 4 is mounted on the working platform 1. In this embodiment, a magnetic base is used for the magnetic suction device. The shape of the magnetic suction device 4 matches the inner wall of the embedded junction box 12. In use, according to the predetermined position of the embedded junction box 12, the magnetic suction device 4 is attracted to the working platform 1, and then the embedded junction box 12 is fastened to the magnetic suction device 4. The magnetic suction device 4 ensures that the embedded junction box 12 is fixed in position during the concrete pouring process, preventing displacement. In the prior art, the embedded junction box 12 is directly tied to the steel reinforcement frame. However, since the manufacturing process of the steel reinforcement frame is simply tied, the precision is low, and there will be some errors in the specific shape of each tied steel reinforcement frame. Tying the embedded junction box 12 to the steel reinforcement frame makes it even more difficult to guarantee that the embedded junction box 12 can be accurately fixed in the predetermined position. However, using the magnetic suction device 4 can break away from the limitation of the steel reinforcement frame and directly attract the magnetic suction device 4 to the predetermined position on the metal working platform 1, greatly improving the positioning accuracy of the embedded junction box 12 and making the product more consistent.
[0033] Furthermore, it also includes a push-pull device; multiple push-pull devices are connected to the transverse baffle 2 and the longitudinal baffle 3 respectively. The push-pull device drives the transverse baffle 2 and the longitudinal baffle 3 to move, which can facilitate the formation of the pouring mold. Also, after the concrete has solidified, when it is necessary to remove the pouring mold around the precast concrete wall panel, the push-pull device drives the transverse baffle 2 and the longitudinal baffle 3 to move outward, so that the transverse baffle 2 and the longitudinal baffle 3 are separated from the solidified precast concrete component, which facilitates the next hoisting work.
[0034] In existing processing methods, because the casting mold is tightly bonded to the precast concrete wall panel during solidification, it is often necessary to manually knock and vibrate the casting mold to separate it from the precast concrete wall panel. This removal method not only consumes a lot of manual labor but also easily damages the casting mold and may also cause some damage to the appearance and structural integrity of the precast concrete wall panel. The mold removal method of the push-pull device in this application avoids the damage to the casting mold and the precast concrete wall panel caused by manual knocking.
[0035] Furthermore, the push-pull device includes: main support 5, guide slide, slide column 6, push plate 7, transmission rod 8 and handwheel 9;
[0036] The main support 5 is fixed on the working platform 1; two guide slides are opened on the main support 5 along the pushing and pulling direction of the push-pull device, and a sliding column 6 is slidably connected in the guide slide; one end of the sliding column 6 is connected to the transverse baffle 2 or the longitudinal baffle 3 of the pouring mold, and the other end is connected to the push plate 7.
[0037] The transmission rod 8 includes a smooth rod portion near the handwheel 9 and a threaded portion of other parts; the smooth rod portion is cylindrical, and the threaded portion has external threads;
[0038] The transmission rod 8 passes through the main support 5 and the push plate 7. Correspondingly, a matching threaded hole is provided on the main support 5, and the threaded part of the transmission rod 8 is threadedly connected to the threaded hole.
[0039] The push plate 7 is provided with a through hole, and a bearing is fitted into the through hole. The smooth part of the transmission rod 8 passes through the bearing and the push plate 7 and is fixedly connected to the handwheel 9. The push plate 7 and the transmission rod 8 are connected by the bearing. The transmission rod 8 and the bearing are interference fit, so that the transmission rod 8 can rotate freely relative to the push plate 7, and at the same time, the axial movement of the transmission rod 8 is transmitted to the push plate 7.
[0040] In use, turning the handwheel 9 drives the transmission rod 8 to rotate. The transmission rod 8 moves along the axis and drives the push plate 7 to move. The push plate 7 is connected to the slide column 6, so the transmission rod 8 drives the slide column 6 to move through the push plate 7, thereby realizing the effective operation of the injection mold and completing the assembly and disassembly of the mold.
[0041] Furthermore, the transverse baffle 2 and the longitudinal baffle 3 are provided with limiting notches 10. The width of the limiting notches 10 matches the outer diameter of the reinforcing bars, and the depth of the limiting notches 10 is greater than the outer diameter of the reinforcing bars. The limiting notches 10 are used to place the reinforcing bars, and the limiting notches 10 limit the position of the reinforcing bars, ensuring the dimensional accuracy and structural stability of the reinforcing bar skeleton.
[0042] Furthermore, it also includes a limiting plate 11; the limiting plate 11 is disposed outside the transverse baffle 2 and the longitudinal baffle 3; the limiting plate 11 is disposed at the end of the reinforcing bar for limiting the length of the reinforcing bar; in use, one end of the reinforcing bar extends out of the pouring mold and abuts against the limiting plate 11, at which time the length of this extended section of the reinforcing bar is the predetermined extension length. By limiting the position and extension length of the reinforcing bar by the limiting plate 11, the dimensional accuracy and structural stability of the reinforcing bar cage are ensured, and key parameters such as the anchorage length of the reinforcing bar in the precast concrete component meet the design requirements, effectively enhancing the load-bearing capacity and structural safety of the precast concrete component.
[0043] Furthermore, a push-pull device is provided on the rear side of the limiting plate 11, and the position of the limiting plate 11 can be adjusted by the push-pull device.
[0044] Working principle:
[0045] In this embodiment, a precast concrete wall panel is manufactured; the precast concrete wall panel has a pre-embedded steel reinforcement skeleton and a pre-embedded junction box 12.
[0046] First, adjust the positions of the transverse baffle 2 and the longitudinal baffle 3 to form a pouring mold; place the reinforcing bars sequentially within the limiting notches 10 of the transverse baffle 2 and the longitudinal baffle 3 to initially fix the position of the reinforcing bars. At the same time, ensure that one end of the reinforcing bar abuts against the limiting plate 11 so that the length of the reinforcing bar extending reaches the predetermined design value.
[0047] Then, the reinforcing bars are tied with binding wire. After the reinforcing bars are tied, the position of the embedded junction box 12 in the precast concrete component is determined according to the construction drawings. The magnetic suction device 4 is attached to the work platform 1 according to the predetermined position. Then, the embedded junction box 12 is fastened to the magnetic suction device 4 to complete the positioning of the embedded junction box 12.
[0048] Pour the mixed concrete into the casting mold and wait for the concrete to solidify and reach the design strength before removing the mold.
[0049] At this point, operate the push-pull device and slowly turn the handwheel 9 to move the transmission rod 8 axially, driving the push plate 7 to move away from the pouring mold. The push plate 7 drives the transverse baffle 2 and the longitudinal baffle 3 outward through the sliding column 6. During the movement, carefully observe the separation of the baffles from the precast concrete component to ensure that the baffles smoothly detach from the precast component and avoid damage to the precast component and the mold. Once the transverse baffle 2 and the longitudinal baffle 3 are completely detached from the precast concrete component, the mold removal work is complete.
[0050] Finally, using suitable hoisting equipment, such as a crane or tower crane, the precast concrete component is slowly lifted. At this time, the embedded junction box 12 is fixed to the precast concrete wall panel, and the magnetic suction device 4 is attached to the working platform 1. As the hoisting proceeds, the magnetic suction device 4 and the embedded junction box 12 separate, thus completing this processing step.
[0051] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
