Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a rebar positioning device for building construction. Background Technology
[0002] The positioning device is used in construction to fix reinforcing bars and hoops when assembling them into a column. When using the positioning device, a motor drives a pulley to rotate, which in turn drives two first threaded rods to rotate in the same direction via a connecting belt. Then, the second threaded rod is manually controlled to rotate, allowing the round rod to pass through two moving blocks. The four moving blocks can then form a rectangle. The reinforcing bar is then inserted into the corresponding semicircular block to fix it in place. The operator then manually supports the hoops onto the surface of the reinforcing bar and welds the hoops and reinforcing bar together, thus effectively assembling the reinforcing bar and hoops into a rectangular column.
[0003] In their daily work, the inventors discovered that the positioning device still has at least the following problems: When using the positioning device, the motor drives the pulley to rotate, which in turn drives the two first threaded rods to rotate in the same direction through the connecting belt. Then, the second threaded rod is manually controlled to rotate, allowing the round rod to pass through the two moving blocks, so that the four moving blocks can form a rectangle. Then, the reinforcing bar is inserted into the corresponding arc block to fix the reinforcing bar. However, in actual use, in order to fix the reinforcing bar in a certain position, the operator needs to manually support the steel hoop on the surface of the reinforcing bar and then weld the steel hoop and the reinforcing bar together, which is quite troublesome. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rebar positioning device for building construction.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rebar positioning device for building construction, comprising an operating table, a first threaded rod rotatably inserted into one side of the operating table, one end of the first threaded rod being fixedly connected to a pulley, a connecting belt being sleeved on the surface of the two pulleys, a motor being fixedly connected to one side of the operating table, the output end of the motor being fixedly connected to one side of the pulleys, the thread direction of the first threaded rod being opposite from the middle to both sides, a movable rod being threadedly sleeved on the surface of the first threaded rod, a support device being provided on one side of the movable rod, and one side of the movable rod being rotatably inserted through... A second threaded rod is provided, and a movable block is threadedly fitted onto the surface of the second threaded rod. The thread direction of the second threaded rod is opposite from the middle to both sides. A round rod is inserted through one side of the movable rod and is slidably inserted into one side of the movable block. An arc block is formed on one side of the movable block, and a limit device is provided on one side of the movable block. The support device includes a sliding block. A sliding groove is formed on one side of the movable rod, and the inner wall of the sliding groove is slidably connected to the sliding block. A connecting groove is formed on one side of the sliding block, and a rotating rod is fixedly connected to the inner wall of the connecting groove. A support strip is rotatably fitted onto the surface of the rotating rod.
[0006] The effect achieved by the above components is as follows: when using the support device, the sliding block is manually controlled to slide on the inner wall of the groove, and then the support bar is manually controlled to rotate on the surface of the rotating rod, so that the support bar is set on one side of the reinforcing bar. This allows the steel hoop to be set on the top of the support bar, so that the steel hoop does not need to be supported by hand, and thus the steel hoop and the reinforcing bar can be easily welded together.
[0007] Preferably, a first bolt is threaded through one side of the sliding block, and the first bolt is located on one side of the moving rod.
[0008] The effect achieved by the above components is as follows: when the sliding block is slid to a suitable position on the inner wall of the groove, the first bolt is manually controlled to rotate, thereby pressing the first bolt against one side of the moving rod, which can effectively fix the sliding block in a suitable position inside the groove.
[0009] Preferably, an extension frame is fitted onto the surface of the support strip, and a rubber plate is fixedly connected to one side of the support strip, with the rubber plate disposed on one side of the inner wall of the extension frame.
[0010] The effect achieved by the above components is: the extension frame is manually controlled to slide out of the surface of the support bar. When the extension frame slides to the appropriate position, the rubber plate is pressed against one side of the inner wall of the extension frame, which can increase the length of the support bar to a certain extent.
[0011] Preferably, an L-shaped plate is slidably inserted through the top of the sliding block, a damping rod is fixedly connected to the bottom of the L-shaped plate, the bottom of the damping rod is fixedly connected to the top of the sliding block, a first spring is sleeved on the surface of the damping rod, one end of the first spring is fixedly connected to the bottom of the L-shaped plate, and the end of the first spring near the damping rod is fixedly connected to the top of the sliding block.
[0012] The effect achieved by the above components is as follows: when the support bar is set on one side of the reinforcing bar, the L-shaped plate is manually inserted into the top of the sliding block, and the L-shaped plate is pulled towards the sliding block by the first spring, thereby restricting the L-shaped plate to one side of the support bar, so that the support bar can be restricted to one side of the reinforcing bar.

[0014] The effect achieved by the above components is as follows: when using the limiting device, the locking block is slid into the first limiting groove, and then the fixing rod is inserted into the top of the moving block and then into the small hole. The locking block restricts the steel bar to one side of the moving block.
[0015] Preferably, a second spring is sleeved on the surface of the fixing rod, one end of the second spring is fixedly connected to the top of the fixing rod, and the end of the second spring near the fixing rod is fixedly connected to the top of the moving block.
[0016] The effect achieved by the above components is that the fixing rod is pulled closer to the moving block by the second spring, thereby effectively confining the fixing rod inside the small hole.
[0017] Preferably, a second bolt is threaded through one side of the locking block, and a pressing block is fixedly connected to one end of the second bolt.
[0018] The effect achieved by the above components is that the second bolt is manually rotated, thereby causing the extrusion block to press against one side of the reinforcing bar, which can effectively restrict different types of reinforcing bars to one side of the moving block.
[0019] Preferably, a second limiting groove is provided on one side of the movable block, a sliding rod is fixedly connected to the inner wall of the second limiting groove, a rectangular block is slidably sleeved on the surface of the sliding rod, a locking rod is fixedly connected to one side of the rectangular block, and the locking rod is slidably inserted into one side of the locking block.
[0020] The effect achieved by the above components is that by inserting the locking rod into one side of the locking block, the locking block can be effectively restricted to one side of the moving block.
[0021] In this utility model, by setting a support device, when using the support device, the sliding block is manually controlled to slide on the inner wall of the groove, and then the support bar is manually controlled to rotate on the surface of the rotating rod, so that the support bar is set on one side of the reinforcing bar. This allows the steel hoop to be set on the top of the support bar in a good way, so that the steel hoop does not need to be supported by hand, and thus the steel hoop and the reinforcing bar can be easily welded together.

[0027] Example 1, as Figure 1-4As shown, a rebar positioning device for building construction includes a first threaded rod 2 rotatably inserted into one side of an operating platform 1. One end of each threaded rod 2 is fixedly connected to a pulley 3, and a connecting belt 4 is fitted onto the surface of both pulleys 3. A motor 5 is fixedly connected to one side of the operating platform 1, and the output end of the motor 5 is fixedly connected to one side of the pulleys 3. The thread direction of the first threaded rod 2 is opposite from the center outwards. A moving rod 6 is threaded onto the surface of the first threaded rod 2, and a support device 7 is provided on one side of the moving rod 6. A second threaded rod 9 is rotatably inserted into one side of the moving rod 6, and a moving block 10 is threaded onto the surface of the second threaded rod 9. The thread direction of the second threaded rod 9 is opposite from the center outwards. A moving block 10 is inserted into one side of the moving rod 6. A round rod 11 is provided, which is slidably inserted into one side of the movable block 10. An arc block 12 is provided on one side of the movable block 10, and a limit device 8 is provided on one side of the movable block 10. When using the positioning device, the motor 5 drives the pulley 3 to rotate, which in turn drives the two first threaded rods 2 to rotate in the same direction through the connecting belt 4. Then, the second threaded rod 9 is manually controlled to rotate, so that the round rod 11 can pass through the two movable blocks 10, so that the four movable blocks 10 can form a rectangle. Then, the steel bar is inserted into the corresponding arc block 12 to fix the steel bar. Then, the operator needs to manually support the steel hoop on the surface of the steel bar, and then weld the steel hoop and the steel bar together to form a rectangular column.
[0028] Reference Figure 2The support device 7 includes a sliding block 702. A groove 701 is provided on one side of the moving rod 6. The inner wall of the groove 701 is slidably connected to the sliding block 702. A connecting groove 703 is provided on one side of the sliding block 702. A rotating rod 704 is fixedly connected to the inner wall of the connecting groove 703. A support strip 705 is rotatably sleeved on the surface of the rotating rod 704. When using the support device 7, the sliding block 702 is manually controlled to slide on the inner wall of the groove 701, and then the support strip 705 is manually controlled to rotate on the surface of the rotating rod 704, so that the support strip 705 is positioned on one side of the reinforcing bar. This effectively... The steel hoop is placed at the top of the support bar 705, eliminating the need for manual support and facilitating welding of the hoop and reinforcing bar together. A first bolt 711 is threaded through one side of the sliding block 702 and positioned on one side of the moving rod 6. When the sliding block 702 slides to a suitable position on the inner wall of the groove 701, the first bolt 711 is manually rotated, pressing against one side of the moving rod 6. This effectively fixes the sliding block 702 in a suitable position within the groove 701. An extension sleeve is fitted onto the surface of the support bar 705. A rubber plate 707 is fixedly connected to one side of the support bar 705 in the long frame 706. The rubber plate 707 is set on one side of the inner wall of the extension frame 706. The extension frame 706 is manually controlled to slide out of the surface of the support bar 705. When the extension frame 706 slides to the appropriate position, the rubber plate 707 is pressed against one side of the inner wall of the extension frame 706, which can lengthen the support bar 705 to a certain extent. An L-shaped plate 708 is slidably inserted through the top of the sliding block 702. A damping rod 709 is fixedly connected to the bottom of the L-shaped plate 708. The bottom of the damping rod 709 and the top of the sliding block 702 are fixedly connected. A first spring 710 is fitted on the surface of the damping rod 709. One end of the first spring 710 is fixedly connected to the bottom of the L-shaped plate 708, and the end of the first spring 710 near the damping rod 709 is fixedly connected to the top of the sliding block 702. When the support bar 705 is set on one side of the reinforcing bar, the L-shaped plate 708 is manually inserted into the top of the sliding block 702. The L-shaped plate 708 is pulled towards the sliding block 702 by the first spring 710, thereby restricting the L-shaped plate 708 to one side of the support bar 705. This allows the support bar 705 to be restricted to one side of the reinforcing bar.
[0029] Reference Figure 3 and Figure 4The limiting device 8 includes a fixed rod 803. A first limiting groove 801 is provided on one side of the movable block 10. A locking block 802 is slidably connected to the inner wall of the first limiting groove 801. A small hole 811 is provided on the top of the locking block 802. The fixed rod 803 is slidably inserted through the top of the movable block 10. The inner wall of the small hole 811 is slidably connected to the fixed rod 803. When using the limiting device 8, the locking block 802 is slid into the first limiting groove 801, and then the fixed rod 803 is inserted into the top of the movable block 10 and then into the small hole 811. The locking block 802 restricts the steel bar to one side of the movable block 10. A second spring 804 is sleeved on the surface of the fixed rod 803. One end of the second spring 804 is fixedly connected to the top of the fixed rod 803, and the end of the second spring 804 near the fixed rod 803 is fixedly connected to the top of the movable block 10. The second spring 804 moves the movable block 10 closer to the fixed rod. Pulling the fixing rod 803 in the direction of block 10 effectively restricts the fixing rod 803 inside the small hole 811. A second bolt 805 is threaded through one side of the locking block 802. One end of the second bolt 805 is fixedly connected to a pressing block 806. Manually controlling the rotation of the second bolt 805 causes the pressing block 806 to press against one side of the steel bar, thus effectively restricting steel bars of different types to one side of the moving block 10. A second limiting groove 807 is provided on one side of the moving block 10. A sliding rod 808 is fixedly connected to the inner wall of the second limiting groove 807. A rectangular block 809 is slidably fitted on the surface of the sliding rod 808. A locking rod 810 is fixedly connected to one side of the rectangular block 809. The locking rod 810 is slidably inserted into one side of the locking block 802. Inserting the locking rod 810 into one side of the locking block 802 effectively restricts the locking block 802 to one side of the moving block 10.
[0030] Working principle: When using the positioning device, the motor 5 drives the pulley 3 to rotate, which in turn drives the two first threaded rods 2 to rotate in the same direction via the connecting belt 4. Then, the second threaded rod 9 is manually controlled to rotate, allowing the round rod 11 to pass through the two moving blocks 10, so that the four moving blocks 10 can form a rectangle. The reinforcing bar is then inserted into the corresponding arc block 12 to fix it in place. The operator then manually supports the steel hoop onto the surface of the reinforcing bar and welds the steel hoop and the reinforcing bar together, thus forming a rectangular column. When using the support device 7, the sliding block 702 is manually controlled within the groove 701. When the sliding block 702 is slid into the appropriate position on the inner wall of the slide groove 701, the first bolt 711 is manually rotated, causing it to press against one side of the moving rod 6. This effectively fixes the sliding block 702 in the appropriate position inside the slide groove 701. Then, the support bar 705 is manually rotated on the surface of the rotating rod 704, and the extension frame 706 is manually slid out of the surface of the support bar 705. When the extension frame 706 slides into the appropriate position, the rubber plate 707 presses against one side of the inner wall of the extension frame 706, which can lengthen the support bar 705 to a certain extent. When setting the L-shaped plate 708 on one side of the reinforcing bar, manually control the L-shaped plate 708 to be inserted into the top of the sliding block 702. The first spring 710 pulls the L-shaped plate 708 towards the sliding block 702, thus restricting the L-shaped plate 708 to one side of the support bar 705. This restricts the support bar 705 to one side of the reinforcing bar, allowing the steel hoop to be positioned effectively on top of the support bar 705 without manual support, facilitating welding the steel hoop and reinforcing bar together. When using the limiting device 8, insert the locking rod 810 into one side of the locking block 802. The locking block 802 is effectively restricted to one side of the moving block 10. The locking block 802 is slid into the first limiting groove 801, and then the fixing rod 803 is inserted into the top of the moving block 10 and into the small hole 811. The fixing rod 803 is pulled towards the moving block 10 by the second spring 804, thus effectively restricting the fixing rod 803 into the small hole 811. The locking block 802 restricts the steel bar to one side of the moving block 10. The second bolt 805 is manually rotated, so that the pressing block 806 presses against one side of the steel bar, thus effectively restricting steel bars of different types to one side of the moving block 10.
