When binding the reinforcing bars, the longitudinal bars and stirrups need to be precisely positioned. Furthermore, the concrete needs to be vibrated during the pouring of concrete. During the vibration of the concrete, the reinforcing bar skeleton of the column structure is prone to displacement, causing the reinforcing bar skeleton to become skewed, or even resulting in exposed reinforcing bars, which seriously affects the production efficiency and quality of precast components.
[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0034] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.
[0035] According to specific embodiments of this application, such as Figure 1-3 As shown, this application provides a column-type rebar positioning device. The positioning device includes a base plate 1, on which two guide holes are symmetrically arranged; the base plate 1 is provided with a longitudinal bar 200 positioning mechanism and a stirrup 300 positioning mechanism.
[0036] The longitudinal reinforcement 200 positioning mechanism includes:
[0037] There are two longitudinal rib stops 3, which are guided to move in two guide holes respectively, and limit the longitudinal rib 200 by the inner side of the longitudinal rib stops 3.
[0038] The double-ended stud 4 has two threads with opposite directions at both ends. The longitudinal rib block 3 has a threaded hole, and the threads in the two longitudinal rib blocks 3 have opposite directions. The two ends of the double-ended stud 4 are threaded into the threaded holes of the two longitudinal rib blocks 3 respectively.
[0039] In this column-type rebar positioning device, two longitudinal rebar stops 3 in the longitudinal rebar 200 positioning mechanism can limit the two longitudinal rebars 200 in the horizontal direction to ensure the accuracy of the column rebar's horizontal position. Furthermore, the two longitudinal rebar stops 3 are simultaneously connected by double-ended studs 4. When the double-ended studs 4 are rotated, the two longitudinal rebar stops 3 move towards or away from each other, realizing the adjustment of the distance between the two longitudinal rebar stops 3. This allows the positioning device to be applied to column-type rebar structures of different widths, greatly improving the application range of the positioning device.
[0040] The positioning device also includes a handle 2, which spans across the base plate 1. Rotating holes are provided on both sides of the handle 2, and the two ends of the double-headed stud 4 are respectively rotatably disposed in the rotating holes on both sides of the handle 2.
[0041] In this embodiment, the handle 2 can be split along the horizontal center line of the rotating hole, that is, the handle 2 is divided into an upper part and a lower part. The upper part and the lower part of the handle 2 are provided with flange edges at their mating positions, and the flange edges of the upper part and the lower part of the handle 2 are connected by bolts.
[0042] Install bearing bushes in the upper and lower halves of the handle 2 respectively. After inserting the two ends of the double-ended stud 4 into the lower half of the handle 2, align and connect the upper and lower halves of the handle 2. This arrangement makes it easier to install the bearing bushes and the double-ended stud 4.
[0043] The positioning mechanism of the stirrup 300 includes: an adjusting screw 8, which is rotatably mounted on the base plate 1, and a rotating bearing 9 is provided between the top of the adjusting screw 8 and the base plate 1; a nut is also threadedly connected to the bottom of the adjusting screw 8.
[0044] In this embodiment, the rotating bearing 9 can be a ball bearing, a roller bearing, or a thrust ball bearing; no specific limitation is made here.
[0045] The positioning mechanism of the stirrup 300 also includes an adjusting plate 7, which has a threaded hole at its center. An adjusting screw 8 is threaded into the threaded hole of the adjusting plate 7. The adjusting plate 7 can be moved up and down by rotating the adjusting screw 8.
[0046] In this embodiment, by rotating the adjusting screw 8, the adjusting plate 7 can be displaced vertically along the adjusting screw 8, thereby adjusting the position of the adjusting plate 7 in the vertical direction.
[0047] The stirrup 300 positioning mechanism also includes multiple stirrup support rods 6, all of which are fixed below the adjusting plate 7.
[0048] In this embodiment, two stirrup support rods 6 are provided, which are used to support the stirrups 300. When the adjusting plate 7 moves up and down, it can drive the stirrup support rods 6 to move up and down simultaneously, so that the stirrup support rods 6 can be used in column steel bars with different parameters.
[0049] The stirrup support rod 6 is L-shaped, and the top of one side of the L-shaped stirrup support rod 6 is fixed to the adjusting plate 7.
[0050] In this embodiment, the top of the vertical side of the L-shaped stirrup support rod 6 is fixed to the bottom surface of the adjustment plate 7, and the horizontal side of the L-shaped stirrup support rod 6 extends outward, supporting the stirrup 300 through the outwardly extended horizontal side.
[0051] Both sides of the adjusting plate 7 are provided with stop bars 5, which extend outward in the horizontal direction.
[0052] A long through hole is provided on the longitudinal rib block 3, and the stop bar 5 extends into the long through hole of the longitudinal rib block 3.
[0053] In this embodiment, the long through hole on the longitudinal rib block 3 extends through the entire longitudinal rib block 3 and extends vertically. When the adjusting screw 8 rotates to drive the adjusting plate 7 to move up and down, since the stop rod 5 extends into the long through hole of the longitudinal rib block 3, the long through hole of the longitudinal rib block 3 can restrict the stop rod 5 from rotating, thereby restricting the rotation of the adjusting plate 7, so that the adjusting plate 7 can be effectively adjusted in the vertical direction.
[0054] The handle 2 has a U-shaped structure and is mounted horizontally across the base plate 1.
[0055] In this embodiment, the U-shaped handle 2 is horizontally mounted on the substrate 1, and both longitudinal rib blocks 3 are located inside the U-shaped handle 2; the two ends of the double-headed stud 4 are respectively rotatably mounted in the rotating holes on both sides of the handle 2, so that the handle 2 supports the double-headed stud 4, thereby ensuring the stable operation of the longitudinal rib 200 positioning mechanism.
[0056] A bearing is provided between the rotating hole of the handle 2 and the end of the double-ended stud 4.
[0057] In this embodiment, a bearing is provided between the rotating hole of the handle 2 and the end of the double-ended stud 4 to reduce the friction between the handle 2 and the double-ended stud 4; in other embodiments, a bearing may also be provided between the rotating hole of the handle 2 and the end of the double-ended stud 4, which is not specifically limited here.
[0058] The working principle of the positioning device is as follows: First, the longitudinal bars 200 and stirrups 300 of the column steel structure are placed in the casting mold 100. Then, the base plate 1 of the positioning device is placed on the casting mold 100. The double-headed stud 4 is rotated to adjust the distance between the two longitudinal bar stops 3. The distance between the two longitudinal bar stops 3 is adjusted to the set position so that the two longitudinal bars 200 at the top of the column steel structure contact each other with the inner side of the two longitudinal bar stops 3, thereby realizing the positioning of the longitudinal bars 200 in the column steel structure.
[0059] Then, turn to the adjusting screw 8, so that the adjusting plate 7 drives the stirrup support rod 6 to move up and down, so as to adjust the stirrup support rod 6 to the set position, so that the stirrup support rod 6 supports the top of the stirrup 300 in the column steel structure, thereby realizing the positioning of the stirrup 300 in the column steel structure.
[0060] Multiple positioning devices can be installed in the casting mold 100 to ensure the accuracy of the positioning of the column steel reinforcement structure in the casting mold 100. After the positioning devices complete the positioning of the longitudinal bars 200 and stirrups 300 in the column steel reinforcement structure, the longitudinal bars 200 and stirrups 300 are tied together. Then, concrete is poured into the casting mold 100 and vibrated. After the vibration operation is completed and the concrete has initially set, the positioning devices are moved backward in the direction of the stirrups 300, and then the positioning devices are removed from the casting mold 100. This positioning device is beneficial to improving the production efficiency and quality of column steel reinforcement precast components. It has wide applicability, is simple and convenient to operate, and is easy to reuse.
[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
