Description

Technical Field

[0001] This utility model relates to the field of anchor bolt positioning technology; specifically, this utility model relates to an anchor bolt control device for the contact wire foundation of a shield A-wall. Background Technology

[0002] The catenary anchor bolts on the A-wall of the shielding plate are a product of a typical "integrated" design concept in high-speed railway bridge construction. Utilizing the bridge's own shielding plate structure as a carrier, they firmly connect the catenary support pillars that support the power supply conductors to the bridge via pre-embedded high-strength anchor bolts. This saves space, optimizes the structure, and ensures the stability and reliability of the catenary system.

[0003] In the construction of contact wire foundation anchor bolts, the positioning effect of the anchor bolts directly affects the forming quality of the anchor bolts in the reserved groove. In the traditional construction process, the anchor bolts are directly welded to the wall reinforcement to form the anchor bolt positioning by relying on manual measurement and calibration. However, in this method, during the pouring of wall concrete and the construction of other equipment in the wall, buoyancy, impact force and vibration force can easily cause the anchor bolt position to shift or the anchor bolt to tilt, thus affecting the forming effect of the anchor bolts. In view of this, this application provides a contact wire foundation anchor bolt control device for a shielded A wall. Utility Model Content

[0004] In view of this, the present invention provides a control device for the anchor bolts of the contact wire foundation of the shield A wall, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0005] To achieve the aforementioned objective, this utility model provides a control device for anchor bolts on the foundation of a contact network in a shielded A-wall, comprising a template, a through hole, a protective sleeve, and a first nut. The through hole is provided on the template for the anchor bolt to pass through. The outer diameter of the protective sleeve is larger than the size of the through hole. The protective sleeve is used to cover the exposed portion of the anchor bolt. The first nut can be threaded onto the exposed end of the anchor bolt.

[0006] Preferably, the through hole is a strip-shaped hole, and the width of the through hole is greater than the outer diameter of the anchor bolt.

[0007] Preferably, a cover plate is fixedly fitted at the bottom end of the protective sleeve, the size of the cover plate being larger than the size of the through hole, and the cover plate being able to cover the through hole.

[0008] Preferably, the protective sleeve includes an upper sleeve body and a lower sleeve body, the bottom end of the upper sleeve body is inserted into the lower sleeve body, and the bottom end of the upper sleeve body is threadedly connected to the upper sleeve body.

[0009] Preferably, an outer annular groove is provided on the outer side of the bottom of the upper sleeve, and an inner annular groove is provided on the top of the inner side of the lower sleeve. The inner walls of the outer annular groove and the inner annular groove are provided with matching threads, and the inner diameters of the upper sleeve and the lower sleeve are the same.

[0010] Preferably, the first nut is fixedly connected to the top end of the upper sleeve, and the inner diameter of the protective sleeve is larger than the outer diameter of the anchor bolt.

[0011] Preferably, a sleeve block is fixedly connected to the bottom of both sides of the protective sleeve, an adjusting bolt is slidably inserted inside the sleeve block, a connecting block is fixedly connected to one end of the adjusting bolt, the connecting block is fixedly installed on the template surface, and two adjusting nuts are threadedly connected to the adjusting bolt, which are respectively located on both sides of the sleeve block.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects: The combination of the template, protective sleeve, and first nut effectively positions the anchor bolt, improving its stability and enhancing its resistance to buoyancy, vibration, and impact, thereby improving the anchor bolt's forming effect. Simultaneously, the threaded engagement of the first nut with the anchor bolt, supported by the protective sleeve at the bottom of the first nut, allows for adjustment of the anchor bolt's exposed height, resulting in better pre-embedding.

Detailed Implementation

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 1 and Figure 2As shown, a control device for anchor bolts on the foundation of a contact network of a shielding wall includes a template 1, a through hole 2, a protective sleeve 3, and a first nut 4. The through hole 2 is provided on the template 1 for the anchor bolt to pass through. The outer diameter of the protective sleeve 3 is larger than the size of the through hole 2. The protective sleeve 3 is used to fit over the exposed part of the anchor bolt. The first nut 4 can be threaded onto the exposed end of the anchor bolt.

[0017] During use, first, install template 1 to the preset position, place protective sleeve 3 on template 1, then connect the first nut 4 to the exposed end of the anchor bolt, and pass the bottom end of the anchor bolt through protective sleeve 3 and through hole 2 in sequence. Next, adjust the position of the anchor bolt and adjust the exposed height of the anchor bolt by rotating the first nut 4. Finally, weld the bottom end of the anchor bolt to the wall reinforcement. After the wall is poured, template 1 not only forms a pre-reserved groove, but also, template 1, along with protective sleeve 3 and first nut 4, achieves further positioning of the anchor bolt, improving its stability, thereby enhancing its anti-floating and anti-vibration performance, effectively mitigating bolt displacement, and ensuring precise bolt positioning.

[0018] Optionally, the through hole 2 is a strip-shaped hole, and the width of the through hole 2 is greater than the outer diameter of the anchor bolt. Specifically, the orientation of the strip-shaped hole is perpendicular to the length of the wall. By setting an adjustment hole, on the one hand, it makes it easier for the anchor bolt to pass through the strip-shaped hole, thus facilitating construction operations; on the other hand, it allows the anchor bolt to be fine-tuned within the strip-shaped hole, thereby allowing for construction errors and improving practicality.

[0019] After the anchor bolts are positioned and welded to the wall reinforcement, the first nut 4 is tightened further. The first nut 4 can stably press the protective sleeve 3 onto the template 1. On the one hand, it can further fix the protective sleeve 3, and on the other hand, it can increase the overall stability of the protective sleeve 3 and the template 1, thereby improving the positioning effect of the exposed end of the anchor bolt.

[0020] Optionally, a cover plate 5 is fixedly fitted at the bottom of the protective sleeve 3. The size of the cover plate 5 is larger than the size of the through hole 2, and the cover plate 5 can cover the through hole 2. By setting the cover plate 5, on the one hand, the contact area between the protective sleeve 3 and the template 1 can be increased, making the force between the protective sleeve 3 and the template 1 more uniform and balanced. On the other hand, by covering the through hole 2, the leakage prevention performance is achieved, preventing concrete grout from overflowing from the through hole 2 and ensuring the molding effect of the anchor bolt.

[0021] Optionally, the protective sleeve 3 includes an upper sleeve 31 and a lower sleeve 32. The bottom end of the upper sleeve 31 is inserted into the lower sleeve 32, and the bottom end of the upper sleeve 31 is threadedly connected to the lower sleeve 32. This configuration allows the height of the protective sleeve 3 to be adjusted, thus better adapting to different preset exposed lengths of anchor bolts in different construction scenarios.

[0022] Optionally, an outer annular groove 6 is provided on the outer side of the bottom of the upper sleeve 31, and an inner annular groove 7 is provided on the top of the inner side of the lower sleeve 32. The inner walls of the outer annular groove 6 and the inner annular groove 7 are provided with matching threads, and the inner diameters of the upper sleeve 31 and the lower sleeve 32 are the same.

[0023] Optionally, the first nut 4 is fixedly connected to the top of the upper sleeve 31, and the inner diameter of the protective sleeve 3 is larger than the outer diameter of the anchor bolt. Connecting the first nut 4 to the upper sleeve 31 as a whole can prevent the first nut 4 from being lost, and at the same time, it is easier to carry and transfer. When the protective sleeve 3 is disassembled from the anchor bolt, simply rotate the upper sleeve 31, so that the upper sleeve 31 drives the first nut 4 to rotate upward on the anchor bolt. During this process, the upper sleeve 31 also rotates upward on the smaller sleeve.

[0024] Optionally, a sleeve block 8 is fixedly connected to the bottom of both sides of the protective sleeve 3. An adjusting bolt 9 is slidably inserted inside the sleeve block 8. A connecting block 10 is fixedly connected to one end of the adjusting bolt 9. The connecting block 10 is fixedly installed on the surface of the template 1. Two adjusting nuts 11 are threadedly connected to the adjusting bolt 9, which are located on both sides of the sleeve block 8 respectively.

[0025] During use, first remove the adjusting nut 11 on the adjusting bolt 9 that is away from the connecting block 10. Then, put the sleeve block 8 on the adjusting bolt 9, and then reinstall the removed adjusting nut 11 onto the adjusting bolt 9. Next, slide the protective sleeve 3 along the length of the adjusting bolt 9 according to the position of the through hole 2. Then, pass the anchor bolt through the through hole 2 from bottom to top, and thread the top of the anchor bolt to the first nut 4. Then, by rotating the two second nuts on the adjusting bolt 9, precisely adjust the position of the protective sleeve 3, thereby finely adjusting the position of the anchor bolt and the protective sleeve 3 according to the preset installation position of the anchor bolt. After fine adjustment, the two second nuts clamp the sleeve block 8 from both sides, which can stably position the anchor bolt and the protective sleeve 3. Finally, by rotating the upper sleeve 31, adjust the height of the anchor bolt so that the anchor bolt reaches the preset exposed height. Then, weld the bottom end of the anchor bolt to the wall reinforcement.

[0026] This configuration allows for fine-tuning of the anchor bolt position during construction, improving its accuracy. Simultaneously, it enables real-time locking of the anchor bolt position during fine-tuning. Furthermore, it allows for precise adjustment and fixation of the protective sleeve 3 based on the anchor bolt's location, further enhancing the anchor bolt's forming effect.

[0027] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
