Description

Technical Field

[0001] This utility model relates to the technical field of rebar placement equipment, specifically to a handheld rebar placement device. Background Technology

[0002] With increasing urbanization and the growing number of municipal works, rail transit, and building constructions, steel reinforcement binding is required during the construction of station main structures, including the side walls, corners, and structural slabs. Most of this binding involves tie rods to connect and secure the inner and outer steel bars. In subway station structural construction, the bent-anchor tie rods enhance the overall stability and strength of the building, preventing deformation or damage under stress. The specifications of the steel reinforcement binding are a crucial factor in determining whether the station's main structure meets construction strength requirements.

[0003] Traditional tie bar construction involves processing the tie bars (with curved ends) and then adjusting them by manually dragging them on site. However, the steel bars have high rigidity, making it difficult to meet the specifications by manually bending and anchoring them. Furthermore, the construction process is time-consuming, requires a large number of personnel, and yields low results. Utility Model Content

[0004] To address the technical problem that existing manual rebar bending and anchoring methods cannot meet the specifications, this utility model provides a handheld rebar arrangement device that can mechanically bend the straight and curved ends of the rebars on site to ensure that the bending and anchoring meet the specifications, improve construction efficiency and reduce labor costs.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model provides a handheld rebar arrangement device, comprising: a support; a first limiting seat, installed at one end of the support, abutting against the inner row of rebars in the working state; a second limiting seat, installed at the other end of the support, abutting against the outer row of rebars in the working state; a bending seat, hinged to the second limiting seat in the middle; and a bending linear actuator, installed on the second limiting seat, with one end hinged to one end of the bending seat; wherein, when the bending linear actuator is retracted, the space between the bending seat and the second limiting seat can accommodate the straight and bent ends of the rebars; and when the bending linear actuator is extended, the bending seat rotates away from the bending linear actuator to press the straight and bent ends of the rebars at an angle.

[0007] The handheld rebar arranging device provided by this utility model includes a bracket, a first limiting seat, a second limiting seat, a bending seat, and a bending linear actuator. The first limiting seat and the second limiting seat are respectively installed at one end of the bracket. In the working state, the first limiting seat abuts against the inner row of rebars and the second limiting seat abuts against the outer row of rebars. The middle part of the bending seat is hinged to the second limiting seat. The bending linear actuator is installed on the second limiting seat and one end is hinged to one end of the bending seat. When the bending linear actuator extends, the bending seat rotates away from the bending linear actuator to press the straight and bent ends of the rebars at an angle.

[0008] In use, retract the arc bending linear actuator to allow the space between the arc bending seat and the second limiting seat to accommodate the straight bending end of the tie bar. Then, extend the handheld rebar placement device into the rebar cage, so that the first limiting seat abuts against the inner row of rebars and the second limiting seat abuts against the outer row of rebars. The inner and outer rows of rebars are supported by the bracket. Then, hang the inclined bending section of the tie bar on the inner row of rebars, and place the straight bending section of the tie bar in the space between the arc bending seat and the second limiting seat. Finally, control the arc bending linear actuator to extend, causing the arc bending seat to rotate away from the arc bending linear actuator, so as to press the straight bending end of the tie bar at an angle through mechanical bending, thereby ensuring that the bending anchor meets the specification requirements.

[0009] When using the handheld rebar arrangement device provided by this utility model to perform rebar bending, it is only necessary to control the extension and retraction of the arc bending linear actuator and insert it into the rebar cage. There is no need for manual bending, which can not only improve construction efficiency, but also reduce labor costs.

[0010] In an optional embodiment of this application, the support is a telescopic frame; it also includes a spacing linear actuator, which is installed between the first limiting seat and the second limiting seat to control the spacing between the first limiting seat and the second limiting seat by telescoping the spacing linear actuator. This mechanically adjusts the spacing between the inner and outer rows of reinforcing bars, ensuring that the spacing between the inner and outer rows of reinforcing bars meets the design requirements. This achieves the integration of the spacing device and the reinforcing bar bending device, reducing device costs while further improving the efficiency of reinforcing bar arrangement.

[0011] In an optional embodiment of this application, the bracket includes: a fixed rod, one end of which is fixedly connected to the first limiting seat and the other end of which extends toward the second limiting seat; and a telescopic rod, one end of which is fixedly connected to the second limiting seat and the other end of which is slidably connected to the end of the fixed rod facing the second limiting seat, so as to ensure that the bracket can extend and retract.

[0012] In an optional embodiment of this application, one end of the telescopic rod that is slidably connected to the fixed rod is inserted into the fixed rod body to ensure the stability of the support's telescopic movement.

[0013] In an optional embodiment of this application, both the fixed rod and the telescopic rod are rectangular tubes to ensure that the bracket has sufficient telescopic stability while also having sufficient rigidity.

[0014] In an optional embodiment of this application, both the curved linear actuator and the spacing linear actuator are hydraulic cylinders to ensure that the curved linear actuator and the spacing linear actuator have sufficient output torque.

[0015] In an optional embodiment of this application, the curved linear actuator is adapted to a curved control valve; the spacing linear actuator is adapted to a spacing control valve; and a hydraulic pump is also included, the output end of which is connected to the input ends of both the curved control valve and the spacing control valve, so as to control the operation of the curved linear actuator and the spacing linear actuator respectively.

[0016] In an optional embodiment of this application, the hydraulic pump is a manual pump, so as not to rely on a fixed hydraulic source and improve the portability of the device.

[0017] In an optional embodiment of this application, a first handle is also included, which is fixed to the middle of the bracket to facilitate holding the device in the middle.

[0018] In an optional embodiment of this application, a second handle is further included, which is fixed to the first limiting seat to facilitate holding one end of the device.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] 1. The handheld rebar arrangement device provided by this utility model includes a bracket, a first limiting seat, a second limiting seat, a bending seat, and a bending linear actuator. The first limiting seat and the second limiting seat are respectively installed at one end of the bracket. In the working state, the first limiting seat abuts against the inner row of rebars and the second limiting seat abuts against the outer row of rebars. The middle part of the bending seat is hinged to the second limiting seat. The bending linear actuator is installed on the second limiting seat and one end is hinged to one end of the bending seat. When the bending linear actuator is extended, the bending seat rotates away from the bending linear actuator to press the straight and bent ends of the rebars at an angle. The straight and bent ends of the rebars are pressed at an angle by mechanical bending, thereby ensuring that the bending anchor meets the specifications.

[0021] 2. The handheld rebar arrangement device provided by this utility model only requires controlling the extension and retraction of the arc bending linear actuator and inserting it into the rebar cage during the process of bending the rebar. No manual bending is required, which can not only improve construction efficiency, but also reduce labor costs. Attached Figure Description

[0036] Example

[0037] Combination Figure 1 and Figure 2 This embodiment provides a handheld rebar arrangement device, including: a support 1; a first limiting seat 2, installed at one end of the support 1, abutting against the inner row of rebars 3 in the working state; a second limiting seat 4, installed at the other end of the support 1, abutting against the outer row of rebars 5 in the working state; a bending seat 6, hinged to the second limiting seat 4 in the middle; and a bending linear actuator 7, installed on the second limiting seat 4, with one end hinged to one end of the bending seat 6; wherein, when the bending linear actuator 7 is retracted, the space between the bending seat 6 and the second limiting seat 4 can accommodate the straight and bent ends of the tie bars 8; and when the bending linear actuator 7 is extended, the bending seat 6 rotates away from the bending linear actuator 7 to press the straight and bent ends of the tie bars 8 at an angle.

[0038] It is understood that the support 1 can be a fixed-length frame to accommodate fixed-spacing rebar rows. To facilitate quick insertion of the support 1 into the rebar cage and easy adjustment of the spacing between the inner and outer rebar rows 3 and 5, in this embodiment, the support 1 is a telescopic frame. It also includes a spacing linear actuator 9, installed between the first limiting seat 2 and the second limiting seat 4. The extension and retraction of the spacing linear actuator 9 controls the distance between the first limiting seat 2 and the second limiting seat 4, thereby mechanically adjusting the spacing between the inner and outer rebar rows 3 and 5. This ensures that the spacing between the inner and outer rebar rows 3 and 5 meets design requirements, achieving integration of the spacing device and the rebar bending device 8, reducing device costs while further improving rebar arrangement efficiency.

[0039] Combination Figure 3 Specifically, the bracket 1 includes: a fixed rod 10, one end of which is fixedly connected to the first limiting seat 2 and the other end of which extends toward the second limiting seat 4; and a telescopic rod 11, one end of which is fixedly connected to the second limiting seat 4 and the other end of which is slidably connected to the end of the fixed rod 10 facing the second limiting seat 4, so as to ensure that the bracket 1 can extend and retract.

[0040] In this embodiment, one end of the telescopic rod 11, which is slidably connected to the fixed rod 10, is inserted into the fixed rod 10 to ensure the stability of the extension and retraction of the bracket 1. Alternatively, one end of the telescopic rod 11, which is slidably connected to the fixed rod 10, can be fitted outside the fixed rod 10.

[0041] Both the fixed rod 10 and the telescopic rod 11 are rectangular tubes to ensure that the bracket 1 has sufficient telescopic stability and rigidity. It is understood that the fixed rod 10 and the telescopic rod 11 can also be circular tubes or polygonal tubes, etc.

[0042] It should be understood that the curved linear actuator 7 and the spacing linear actuator 9 can be hydraulic cylinders / hydraulic jacks, lead screw slider mechanisms / threaded jacks, pneumatic cylinders / pneumatic jacks, etc. In this embodiment, both the curved linear actuator 7 and the spacing linear actuator 9 are hydraulic cylinders to ensure that the curved linear actuator 7 and the spacing linear actuator 9 have sufficient output torque.

[0043] Typically, the curved linear actuator 7 is equipped with a curved control valve 12; the spacing linear actuator 9 is equipped with a spacing control valve 13; and a hydraulic pump 14 is also included, the output end of which is connected to the input ends of both the curved control valve 12 and the spacing control valve 13, so as to control the operation of the curved linear actuator 7 and the spacing linear actuator 9 respectively.

[0044] In this embodiment, the hydraulic pump 14 is a manual pump, so as not to rely on a fixed hydraulic source and improve the portability of the device.

[0045] It should be noted that for the linear actuator 9, its two ends can be fixedly connected to the corresponding first limit seat 2 and second limit seat 4 respectively. However, for the curved linear actuator 7, since it needs to drive the curved seat 6 to rotate around the hinge point between it and the second limit seat 4, the curved linear actuator 7 needs to be able to extend and retract, as well as rotate relative to the second limit seat 4 or slide along the length direction of the second limit seat 4. Usually, a hinged method is adopted, that is, one end of the curved linear actuator 7 is hinged to the curved seat 6 and the other end is hinged to the second limit seat 4 (not shown in the figure).

[0046] Based on this, this embodiment also includes a first handle 15, which is fixed in the middle of the bracket 1 to facilitate the use of the handheld device in the middle.

[0047] For ease of operation, this embodiment also includes a second handle 16, which is fixed on the first limiting seat 2 so that one end of the device can be held.

[0048] Specifically, the curved seat 6 is connected to the curved linear actuator 7 and the second limit seat 4 by bolts. The telescopic rod 11 of the second limit seat 4 is welded, the first limit seat 2 is welded to the fixed rod 10, the first handle is welded to the fixed rod 10, and the second handle is welded to the first limit seat 2 at the bottom. The manual hydraulic pump 14 pumps hydraulic fluid to the pitch linear actuator 9 and the curved linear actuator 7 through hydraulic oil pipes.

[0049] In summary, the handheld rebar arranging device provided by this utility model includes a support 1, a first limiting seat 2, a second limiting seat 4, a bending seat 6, a bending linear actuator 7, and a spacing linear actuator 9. The support 1 is telescopic. The first limiting seat 2 and the second limiting seat 4 are respectively installed at one end of the support 1 and the spacing linear actuator 9. In the working state, the first limiting seat 2 abuts against the inner row of rebars 3, and the second limiting seat 4 abuts against the outer row of rebars 5. The middle part of the bending seat 6 is hinged to the second limiting seat 4. The bending linear actuator 7 is installed on the second limiting seat 4, with one end hinged to one end of the bending seat 6. When the bending linear actuator 7 extends, the bending seat 6 rotates away from the bending linear actuator 7 to bend the straight and curved ends of the tie bars 8.

[0050] Combination Figure 2In use, retract the arc bending linear actuator and the spacing linear actuator 9 so that the space between the arc bending seat 6 and the second limiting seat 4 can accommodate the straight bending end of the tie bar 8, and the distance between the corresponding ends of the first limiting seat 2 and the second limiting seat 4 is less than the spacing between the inner and outer reinforcing bars 5 without spacing. Then, insert the handheld reinforcing bar placement device into the reinforcing cage so that the first limiting seat 2 abuts against the inner reinforcing bar 3. Then, close the arc bending control valve, open the spacing control valve 13, and manually pressurize the hydraulic pump 14 to drive the spacing linear actuator 9 to move the second limiting seat 4 so that the second limiting seat 4 abuts against the outer reinforcing bar 5. Figure 3 And through the linear actuator 9, the second limiting seat 4 is driven to continue moving upward, so that the second limiting seat 4 pushes against the outer row of reinforcing bars 5 to the design required spacing ( Figure 4 ), and close the spacing control valve 13, and support the inner row of steel bars 3 and the outer row of steel bars 5 through the bracket 1.

[0051] When the outer row of reinforcing bars 5 and the inner row of reinforcing bars 3 reach the design required spacing, the slanted section of the tie bar 8 (pre-processed, with one end bent at an angle and the other at a straight bend) is hooked onto the inner row of reinforcing bars 3, and the straight bend is placed in the space between the bending seat 6 and the second limit seat 4. Then, the bending control valve 12 is activated to control the extension of the arc bending linear actuator, which drives the bending seat 6 to rotate away from the bending linear actuator 7, so as to press the straight bend end of the tie bar 8 at an angle through mechanical bending. Figure 4 This ensures that the bent anchors meet the specifications. Finally, after securing the tie rods 8 to the main reinforcement bars with wire, depressurize each linear actuator and remove the arrangement device.

[0052] Therefore, when using the handheld rebar arrangement device provided in this embodiment to perform the 8-bend rebar arrangement, it is only necessary to control the extension and retraction of the arc bending linear actuator and insert it into the rebar cage. There is no need for manual bending, which can not only improve construction efficiency but also reduce labor costs.

[0053] In summary, this embodiment makes the binding of the tie rod 8 more compliant with the specifications, can be easily completed even in narrow working areas, and integrates the row spacing control and the bending arc of the tie rod 8, greatly reducing the construction difficulty, making the construction safer and more environmentally friendly, reducing construction costs, reducing labor, and helping to improve construction efficiency.

[0054] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
