Description

Technical Field

[0001] This utility model belongs to the technical field of bolt positioning components, specifically relating to a positioning device for anchor bolts in the foundation of cast-in-place piles for power transmission lines. Background Technology

[0002] During the construction of the cast-in-place pile foundation for power collection lines, the accurate positioning of the anchor bolts is a crucial step in ensuring the stability and safety of the entire structure. If the anchor bolts are misaligned, it may prevent the tower from being installed properly, or cause problems such as vibration and stress concentration during operation, thereby affecting the service life of the tower and the operational safety of the entire power collection line.

[0003] Traditional methods for fixing anchor bolts lack effective overall positioning and securing devices, typically relying on temporary binding or individual fasteners. This method has the following drawbacks: Firstly, during concrete pouring, the impact and fluidity of the concrete can easily cause the anchor bolts to shift and deviate, making it difficult to guarantee their positional accuracy. Secondly, the fixing effect of temporary binding or individual fasteners is unstable and cannot provide sufficient restraint, making the anchor bolts susceptible to changes in position due to external factors during construction.

[0004] Therefore, a device specifically designed for positioning anchor bolts in the foundation piles of power collection lines is needed to improve the installation accuracy and stability of the anchor bolts. Utility Model Content

[0005] This utility model provides a positioning device for anchor bolts in the foundation of cast-in-place piles for power collection lines, so as to improve the installation accuracy and stability of anchor bolts.

[0006] To achieve the above objectives, this utility model provides a positioning device for anchor bolts in the foundation of cast-in-place piles for power collection lines, comprising a limiting ring and a hoop ring. The limiting ring has at least two sets of through holes. The limiting ring is installed inside the retaining formwork frame and is arranged concentrically with the retaining formwork frame. The hoop ring includes two parallel and spaced longitudinal sections and a transition section connecting the two longitudinal sections. The transition section is fitted onto the body of the anchor bolt. The two longitudinal sections pass through a set of through holes and are locked by fasteners, so that the anchor bolt is limited within the limiting gap formed by the limiting ring and the hoop ring.

[0007] Furthermore, the longitudinal section of the hoop is provided with external threads, and the fastener is a nut that mates with the external threads.

[0008] Furthermore, the limiting ring is fixedly connected to the enclosure template frame through multiple symmetrically arranged connectors.

[0009] Furthermore, the connecting components include a traction rod and a buckle plate. The first end of the traction rod is fixedly connected to a limiting ring, and the second end is fixedly connected to the buckle plate. The buckle plate is installed on the top of the enclosure template frame.

[0010] Furthermore, the snap-on panel has a U-shaped structure.

[0011] Furthermore, the snap-on panels are fixedly connected to the enclosure formwork frame by hand-tightening screws.

[0012] Furthermore, the transition section is an arc-shaped transition section.

[0013] Furthermore, the inner side of the transition section has anti-slip teeth or an elastic buffer layer.

[0014] Furthermore, at least one stirrup is fixed to the outside of multiple anchor bolts.

[0015] Furthermore, the inner diameter of the limiting ring is matched with the distribution circle diameter of the anchor bolt, so that the shank of the anchor bolt fits against the inner ring surface of the limiting ring.

[0016] Compared with the prior art, the present invention has at least the following beneficial technical effects: This utility model proposes a positioning device for anchor bolts in the foundation of cast-in-place piles for power collection lines. Through the combined use of a limiting ring and a clamping ring, the anchor bolts are precisely confined to the inner ring of the limiting ring. The inner ring surface of the limiting ring provides an accurate positioning reference for the anchor bolts. The clamping ring is fitted onto the bolt shaft and locked with fasteners, effectively preventing the anchor bolts from swinging horizontally. This ensures the positional accuracy of the anchor bolts and reduces the problem of misalignment between the center of the anchor bolts and the cast-in-place pile due to bolt displacement during concrete pouring. After concrete is poured inside the retaining formwork, the center of the distribution circle of the anchor bolts coincides with the center of the top formwork, meeting the stringent requirements for anchor bolt installation accuracy in the foundation of cast-in-place piles for power collection lines.

[0017] Furthermore, the limiting ring is detachably fixed to the retaining formwork frame via a traction rod and a buckle plate. The buckle plate is a U-shaped arc plate that fits well against the top of the retaining formwork frame. By tightening the hand-tightening screw on the side plate of the buckle plate, the buckle plate can be easily and quickly clamped and fixed to the inner wall of the retaining formwork frame, thus achieving stable fixation of the limiting ring. This fixing scheme is simple to operate, requiring no complicated tools or procedures, and can greatly improve construction efficiency and shorten the construction cycle. Because this positioning device can effectively ensure the installation accuracy and stability of the anchor bolts, it reduces the possibility of displacement and skewness of the anchor bolts during concrete pouring, thus significantly improving the construction quality of the power line cast-in-place pile foundation. It avoids extensive adjustments and repairs later due to inaccurate anchor bolt positioning, reduces construction costs and safety risks, and provides a reliable guarantee for the long-term stable operation of the power line.

[0025] Reference Figure 1 and Figure 2 One embodiment of this utility model provides a positioning device for anchor bolts in the foundation of cast-in-place piles for power collection lines, including a limiting ring 1. The limiting ring 1 is installed in the retaining formwork frame 7. Multiple hoop rings 3 are installed on the inner ring surface of the limiting ring 1, and the hoop rings 3 are sleeved on the rod body of the anchor bolt 5. The limiting ring 1 is a circular ring plate, and multiple sets of through holes are opened on the inner ring surface of the limiting ring 1, each set of through holes including two through holes 2.

[0026] The hoop 3 is U-shaped and has two parallel longitudinal sections and a transition section connecting the ends of the two longitudinal sections. The inner surface of the longitudinal sections is used to fit the surface of the component to be fixed. Both longitudinal sections of the hoop 3 are provided with external threads.

[0027] Optionally, the transition section can be an arc-shaped transition section.

[0028] Optionally, the transition section is a semi-circular transition section, and the inner diameter of the transition section is equal to the outer diameter of the anchor bolt 5.

[0029] Optionally, the inner surface of the transition section is provided with anti-slip teeth or an elastic buffer layer to enhance the friction with the anchor bolt 5.

[0030] Two longitudinal segments of the hoop 3 pass vertically through two through holes 2 respectively; each longitudinal segment of the hoop 3 is fitted with a nut 4. After the hoop 3 and the nut 4 are locked, the anchor bolt 5 is clamped by the hoop 3 in the gap between the limiting ring 1 and the hoop 3; multiple stirrups 6 are fitted and fixed on the outside of the multiple anchor bolts 5. The multiple stirrups 6 are arranged at intervals along the vertical direction.

[0031] In use, first, place the limiting ring 1 on the outside of multiple anchor bolts 5, ensuring that the shank of the anchor bolt 5 is tightly against the inner ring surface of the limiting ring 1. Then, fasten the clamping ring 3 onto the corresponding anchor bolt 5, pass the two longitudinal sections of the clamping ring 3 through the corresponding through holes 2, and then thread the nut 4 onto the end of the clamping ring 3 to lock it in place. At this point, the anchor bolt 5 is limited within the inner ring opening of the limiting ring 1, effectively preventing it from swinging. (Refer to...) Figure 3 and Figure 4 A traction rod 8 is fixed to the outer ring of the limiting ring 1. A buckle plate 9 is fixed to the end of the traction rod 8 away from the limiting ring 1. The buckle plate 9 is fastened to the top of the retaining formwork frame 7. The buckle plate 9 is a U-shaped arc plate. A hand-tightening screw 10 is threadedly connected to the side plate of the buckle plate 9 near the traction rod 8. When the hand-tightening screw 10 is tightened to the locked state, it can press against the inner wall of the retaining formwork frame 7. After the limiting ring 1 is installed inside the retaining formwork frame 7, the buckle plate 9 is fastened to the top of the retaining formwork frame 7. The retaining formwork frame 7 is clamped by tightening the hand-tightening screw 10, thereby fixing the buckle plate 9 to the retaining formwork frame 7. Since the limiting ring 1 and the hoop 3 limit the anchor bolt 5, it is ensured that after the concrete is poured inside the retaining formwork frame 7, the center of the anchor bolt 5 and the center of the top formwork coincide.

[0032] This utility model provides a method for using the anchor bolt positioning device for cast-in-place pile foundations of power collection lines, including the following steps: The limiting ring 1 is fitted onto the outside of multiple anchor bolts 5, ensuring that the shank of the anchor bolt 5 is tightly against the inner ring surface of the limiting ring 1. The hoop 3 is fastened onto the corresponding anchor bolt 5; the hoop 3 is U-shaped, and its opening should be large enough to accommodate the anchor bolt 5. The two longitudinal sections of the hoop 3 are passed through the corresponding sets of through holes 2 on the inner ring surface of the limiting ring 1. Nuts 4 are fitted onto the longitudinal sections of the hoop 3 passing through the through holes 2, and the nuts 4 are tightened to form a threaded connection with the hoop 3 and lock it in place. At this point, the anchor bolt 5 is clamped by the hoop 3 at the inner ring of the limiting ring 1, effectively limiting the swing of the anchor bolt 5. Multiple stirrups 6 are fitted onto the outside of the multiple anchor bolts 5 to enhance the overall stability between the anchor bolts 5. The limiting ring 1 with the anchor bolts 5 fixed is placed inside the retaining formwork frame 7 and concentrically with the retaining formwork frame 7. The buckle plate 9, fixed at the end of the traction rod 8 away from the limiting ring 1, is fastened to the top of the retaining formwork frame 7, ensuring that the buckle plate 9 is flush with the top of the retaining formwork frame 7. The hand-tightening screw 10, threaded onto the side plate of the buckle plate near the traction rod 8, is screwed on, driving the hand-tightening screw 10 towards the inner wall of the retaining formwork frame 7 until it is tightened and pressed against the inner wall of the retaining formwork frame 7, thus fixing the buckle plate 9 to the retaining formwork frame 7. Because the limiting ring 1 and the hoop 3 effectively limit the anchor bolts 5, after concrete is poured inside the retaining formwork frame 7, it can be ensured that the center of the anchor bolts 5 coincides with the center of the top formwork.
