Description

Technical Field

[0001] This application relates to the technical field of pile foundation construction, and in particular to a tool for positioning anchor bolts for pre-embedded pile foundations. Background Technology

[0002] Anchor bolts are crucial components used to secure equipment or structures to a concrete foundation. They prevent equipment from tilting or overturning due to vibration, impact, or displacement during operation, ensuring production safety. Currently, during pile foundation construction, the positioning of pre-embedded anchor bolts is typically done manually by measuring and marking. This method is not only inefficient but also susceptible to the skill level of construction workers and external environmental factors, leading to significant bolt positioning deviations that directly affect the installation quality and stability of the tower.

[0003] In the prior art, Chinese patent document with publication number CN221837621U discloses a positioning template for long anchor bolts of independent pier-type equipment foundations, including a first bracket, a second bracket, and a central connecting steel plate. The first bracket and the second bracket are fixed on the central connecting steel plate, and positioning steel plates are set at both ends of the first bracket and the second bracket. Positioning holes for long anchor bolts are opened on the positioning steel plates. One end of the long anchor bolt passes through the positioning hole and is fixed on the positioning steel plate, and the other end is welded to the positioning plate. By assembling the central connecting steel plate, the positioning bracket, the positioning steel plate, and the long anchor bolts into a unified whole, the technical effect of enhancing the positioning accuracy of long anchor bolts of independent pier-type equipment foundations is achieved.

[0004] However, in the aforementioned patent documents, the positioning steel plate needs to have anchor bolt positioning holes made according to the equipment drawings or installation requirements, which makes it lack versatility. Different equipment installations require different positioning steel plates to be customized and positioning holes to be made according to the drawings. After construction, the positioning steel plate is difficult to reuse in different equipment installations, resulting in material waste and increased usage costs. Utility Model Content

[0005] To improve the versatility of anchor bolt positioning tools, facilitate reuse, and reduce usage costs, this application provides a positioning tool for pre-embedded anchor bolts in pile foundations.

[0006] This application provides a positioning tool for pre-embedded anchor bolts in pile foundations, which adopts the following technical solution: A positioning tool for pre-embedded anchor bolts in pile foundations includes a frame assembly, a positioning assembly, and an adjustment assembly. The frame assembly includes a rectangular frame and a tie rod. The top surface of the rectangular frame has a plurality of first connection holes. One end of the tie rod is detachably connected to any of the first connection holes by bolts. The positioning component includes a positioning frame, each positioning frame having multiple second connection holes. Adjacent positioning frames are detachably connected through the second connection holes and bolts. Multiple positioning frames are connected end to end to form a detachable polygonal structure. Each of the positioning frames has multiple positioning holes for anchor bolts to pass through. The positioning holes are clearance-fitted with the anchor bolts. The adjustment assembly is detachably connected to the outside of the positioning holes. The other end of the pull rod is detachably connected to any of the second connecting holes by bolts. The positioning frame has scale lines along its length.

[0007] By adopting the above technical solution, the positioning frames can be connected end to end through the second connecting hole to form an arbitrary polygonal structure. The positioning holes opened on the positioning frame can accommodate different anchor bolt layouts. The positioning holes and anchor bolts are fitted with a clearance fit, which facilitates the anchor bolts to pass through the positioning holes and be initially positioned. Then, the positioning of the anchor bolts can be finely adjusted by adjusting the component, thereby improving the positioning accuracy. There is no need to customize the positioning steel plate during the construction process. After the construction is completed, the positioning frame and adjusting component can be directly disassembled for easy transportation or storage, reducing the cost of use.

[0008] Optionally, the connecting ends of two adjacent positioning frames form mutually cooperating recesses and protrusions, and a plurality of second connecting holes are provided on both the recesses and the protrusions.

[0009] By adopting the above technical solution, the recessed and protruding parts facilitate the connection and cooperation between positioning frames, and can also reduce the possible height misalignment between adjacent positioning frames. After the second connecting holes of the recessed and protruding parts are aligned, the positioning frames can be connected and fixed by bolts. Multiple positioning rods can be connected to form a suitable polygon according to the layout of the anchor bolts, so that the position of the positioning holes meets the requirements of the drawings.

[0010] Optionally, each positioning frame has two slidably connected connectors, each connector including a connector body and an overlapping portion. The connector body is sleeved on the positioning frame and fixed by a locking member, and adjacent positioning frames are connected and fixed by the overlapping portion.

[0011] By adopting the above technical solution, adjacent positioning frames can be connected end to end by connectors. The connectors can slide on the positioning frames, making it easy to adjust the connection position between the positioning frames. This allows the polygonal structure formed by the connection of the positioning frames to meet the layout of the anchor bolts, and the position of the positioning holes to be more accurate.

[0012] Optionally, the adjusting component includes a positioning nut, which engages with the anchor bolt threadedly to position the height of the anchor bolt.

[0013] By adopting the above technical solution, the installation elevation of the anchor bolts can be fixed by using positioning nuts, thereby improving the control accuracy of the anchor bolt installation height during construction.

[0014] Optionally, the adjustment assembly further includes a fixing block and adjusting bolts. The fixing block is detachably connected to the positioning frame. The positioning nut is located above the fixing block. The fixing block has a through hole in the middle. The diameter of the through hole is larger than that of the positioning hole and smaller than the outer diameter of the positioning nut. Multiple adjusting bolts are provided and are all threadedly connected to the fixing block. The adjusting bolts penetrate into the through hole and abut against the anchor bolts.

[0015] By adopting the above technical solution, the upper end of the anchor bolt passes through the positioning hole and the through hole on the fixing block in sequence. By rotating multiple adjusting bolts, the position of the anchor bolt can be finely adjusted at multiple angles to improve the positioning accuracy. After the multiple adjusting bolts abut against the anchor bolt, the position of the anchor bolt can also be fixed, reducing the displacement of the anchor bolt during construction.

[0016] Optionally, a fixing rod is rotatably connected to one end of the adjusting bolt that abuts against the anchor bolt, and an arc-shaped washer is provided at the end of the fixing rod.

[0017] By adopting the above technical solution, when the position of the anchor bolt is finely adjusted by rotating the adjusting bolt, the fixed rod of the rotating connection does not rotate with the adjusting bolt. The arc-shaped shim is in close contact with the surface of the anchor bolt, and the end of the adjusting bolt does not directly abut against the anchor bolt, thereby reducing the damage to the surface of the anchor bolt during the adjustment process.

[0018] Optionally, a fixing member is provided below the fixing block, the fixing member is slidably connected to the positioning frame, and the fixing member is locked and fixed to the positioning frame by bolts.

[0019] By adopting the above technical solution, the sliding connection fastener makes it easier to adjust the position of the fixing block, reduce the positional deviation of the positioning hole and the through hole, and improve the positioning accuracy.

[0020] Optionally, it also includes a fixing component, which includes a fixing frame, the upper end of which is fixedly connected to the support, and the lower end of which is fixed to the pile foundation template. The fixing frame is a telescopic structure.

[0021] By adopting the above technical solution, the fixing component can be firmly fixed on the foundation template, providing stable support for the positioning frame. During the concrete pouring process, it can reduce the displacement of the anchor bolts and improve the stability of the positioning. The telescopic fixing frame can also adjust the height of the positioning frame within a certain range, thereby adjusting the vertical position of the anchor bolts and improving the elevation control accuracy of the anchor bolts.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The positioning frame can be connected into any polygonal structure. The positioning holes on the positioning frame can accommodate different anchor bolt layouts. The positioning holes perform preliminary positioning of the anchor bolts, and the adjustment components perform precise positioning of the anchor bolts, thereby improving the positioning accuracy. There is no need to customize positioning steel plates during construction. After construction is completed, the positioning frame and adjustment components can be directly disassembled. The modular structure facilitates transportation or storage, effectively reducing the cost of use.

[0023] 2. The multiple adjusting bolts on the fixing block can finely adjust the position of the anchor bolts at multiple angles, improving positioning accuracy. After the multiple adjusting bolts abut against the anchor bolts, the position of the anchor bolts can also be fixed, reducing the displacement of the anchor bolts during construction.

[0024] 3. The fixing components are firmly connected to the foundation template, improving positioning stability. The telescopic fixing frame can adjust the vertical position of the anchor bolts and control their elevation. Attached Figure Description

Detailed Implementation

[0027] The following combination Figures 1 to 7 This application will be described in further detail.

[0028] Example 1: This example discloses a positioning tool for pre-embedded anchor bolts in pile foundations.

[0029] Reference Figures 1 to 3 The anchor bolt positioning tool for pile foundation pre-embedded anchor bolts includes a frame assembly, a positioning assembly, an adjustment assembly, and a fixing assembly. The positioning assembly is connected to the frame assembly, the fixing assembly provides stable support for the frame assembly and the positioning assembly, and the adjustment assembly is connected to the positioning assembly. The positioning assembly performs initial positioning of the anchor bolt 500, and the adjustment assembly performs fine-tuning of the positioning of the anchor bolt 500, thereby improving the positioning accuracy of the anchor bolt 500.

[0030] In this application, the fixing component includes a fixing frame 410. The frame assembly is disposed on the upper side wall of the fixing frame 410, and a support leg 420 is fixedly connected to the lower side wall of the fixing frame 410. The support leg 420 is used to connect the steel mesh or pile foundation formwork to provide stable support for the positioning frame. During the concrete pouring process, it can reduce the displacement of the anchor bolts 500 and improve the positioning stability. In this embodiment, the fixing frame 410 is a telescopic structure, specifically a sliding double-layer sleeve structure. Different limiting holes 411 are opened vertically along the frame body. By cooperating with the limiting pins 412 and the different limiting holes 411, the height of the fixing frame 410 can be adjusted, thereby adjusting the height of the positioning frame and controlling the elevation of the anchor bolts 500.

[0031] Reference Figure 3 In this embodiment, the frame assembly includes a rectangular frame 110 and a tie rod 120. The rectangular frame 110 is fixedly connected to the side wall of the fixed frame 410 away from the support leg 420. Both ends of the rectangular frame 110 have multiple first connecting holes 111 along the length direction. One end of the tie rod 120 has multiple threaded holes corresponding to the first connecting holes 111. The rectangular frame 110 and one end of the tie rod 120 are pre-assembled, and then bolts are threadedly connected to the threaded holes on the tie rod 120 through the corresponding first connecting holes 111.

[0032] The positioning assembly includes positioning frames 210, which are connected end-to-end to form a hexagonal structure. Each positioning frame 210 has multiple positioning holes 211 along its length. The diameter of the positioning holes 211 is larger than the diameter of the anchor bolts 500 to allow the anchor bolts 500 to pass through. In this application, the diameter of the positioning holes 211 is 2mm larger than the diameter of the anchor bolts 500. The positioning frames 210 also have scale lines along their length to help determine the position of the anchor bolts 500. The positioning frames 210 are detachably connected to each other via second connecting holes 212 at their ends and bolts. Specifically, refer to... Figure 4Each positioning frame 210 has a recessed portion 213 and a protruding portion 214 that cooperate with each other at its end. Multiple second connecting holes 212 are provided on the recessed portion 213 and the protruding portion 214 in the direction away from the positioning frame 210. After the recessed portion 213 and the protruding portion 214 of adjacent positioning frames 210 overlap and cooperate with each other, the appropriate second connecting holes 212 on the recessed portion 213 and the protruding portion 214 are aligned, and bolts are inserted and nuts are used to connect and fix the positioning frame 210.

[0033] This application achieves detachable connection of the positioning frame 210 through the cooperation of the second connecting hole 212 and bolts and nuts. The recessed portion 213 and the protruding portion 214 facilitate the connection and cooperation between the positioning frames 210 and reduce the possible height misalignment between adjacent positioning frames 210, thereby reducing the impact on the positioning elevation of the anchor bolts 500. In addition, this application allows for the selection of the lengths of the recessed portion 213 and the protruding portion 214 according to design specifications or project requirements, enabling adjustment of different connection lengths of the positioning frame 210 to accommodate more anchor bolt 500 layouts and expanding the applicability of this application.

[0034] The positioning frame 210 is connected to the rectangular frame 110 via a tie rod 120. One end of the tie rod 120 is connected to the rectangular frame 110 via a first connecting hole 111 and a bolt. Similarly, the other end of the tie rod 120 can engage with the second connecting hole 212 on the positioning frame 210 and be connected via a bolt. In this embodiment, the connection structure of the positioning frame 210 is hexagonal. The position of the positioning hole 211 can accommodate different anchor bolt 500 layouts. For example, the positioning hole 211 can be located at the vertex of the inscribed rectangle of the hexagonal structure, thus accommodating a rectangular layout of four anchor bolts 500. Alternatively, the positioning hole 211 can be located at the intersection of the inscribed circles of the hexagonal structure, thus accommodating a circular layout of six anchor bolts 500. Furthermore, the positioning frame 210 of this application is detachable. Different numbers of positioning frames 210 can be connected to form any polygonal structure to accommodate different anchor bolt 500 layouts.

[0035] In this application, the adjustment component is mounted on the positioning frame 210 and cooperates with the positioning hole 211 to achieve precise positioning of the anchor bolt 500. (Refer to...) Figures 5 to 6In this embodiment, the adjustment component includes a fixing block 320, an adjusting bolt 330, and a positioning nut 310. The fixing block 320 is mounted on the positioning frame 210. A through hole 321 is opened in the middle of the fixing block 320. The through hole 321 is aligned with the positioning hole 211. The upper end of the anchor bolt 500 passes through the positioning hole 211 and the through hole 321 in sequence. The positioning nut 310, which is mounted above the fixing block 320, is threadedly engaged with the anchor bolt 500 to position the height of the anchor bolt 500, thereby reducing the positioning error of the installation elevation of the anchor bolt 500 and improving the control accuracy of the installation height of the anchor bolt 500 during construction. In this application, the diameter of the through hole 321 is larger than that of the positioning hole 211 and smaller than that of the positioning nut 310, to prevent the positioning nut 310 from falling into the through hole 321 and affecting the positioning of the anchor bolt 500 installation elevation. Specifically, in this embodiment, the diameter of the through hole 321 is 2mm larger than that of the positioning hole 211, and the outer diameter of the positioning nut 310 is 2mm larger than that of the through hole 321. The four adjusting bolts 330 are all threaded around the fixing block 320. The adjusting bolts 330 penetrate into the through hole 321 and abut against the anchor bolt 500. By rotating different adjusting bolts 330, the anchor bolt 500 can be pushed to move in different directions, finely adjusting the position of the anchor bolt 500 and improving the positioning accuracy. After multiple adjusting bolts 330 abut against the anchor bolt 500, the position of the anchor bolt 500 can also be fixed, reducing the displacement of the anchor bolt 500 during construction.

[0036] The fixing block 320 can be installed by welding to the corresponding positioning hole 211, or by detachable bolt connection or sliding connection. In this application, in order to facilitate the adjustment of the position of the fixing block 320, reduce the positional deviation between the positioning hole 211 and the through hole 321, and improve the positioning accuracy, the fixing block 320 is slidably connected to the positioning frame 210 in this embodiment. A fixing member 340 is provided below the fixing block 320. The fixing block 320 is slidably connected to the positioning frame 210 through the fixing member 340. After adjusting the position of the through hole 321 to align with the positioning hole 211, the fixing member 340 and the positioning frame 210 can be locked and fixed by bolts. Since the positioning frame 210 has multiple positioning holes 211, different positioning holes 211 require adjustment components for positioning. The fixing block 320 is slidably connected to the positioning frame 210, which can reduce the number of adjustment components set at the positioning holes 211. During use, the fixing block 320 can be slid to the appropriate positioning hole 211 according to the layout of the anchor bolts 500 or the project requirements, and then locked in place. This can save materials and reduce the cost of use.

[0037] In addition, in order to reduce the damage to the surface of the anchor bolt 500 caused by the adjusting bolt 330 during the adjustment process, this application has a fixing rod 331 rotatably connected to the end of the adjusting bolt 330. The fixing rod 331 is slidably connected to the inner wall of the through hole of the fixing block. An arc-shaped washer 332 is provided at the end of the fixing rod 331. The fixing rod 331 does not rotate with the adjusting bolt 330. It directly contacts the anchor bolt 500 through the arc-shaped washer 332. The end of the adjusting bolt 330 does not directly abut against the anchor bolt 500, thereby reducing the damage to the surface of the anchor bolt 500 caused by the adjustment bolt 330 during the rotation process.

[0038] The working principle of Embodiment 1 of this application is as follows: According to the layout of the anchor bolts 500 in the drawings, a suitable number of positioning frames 210 are selected and connected into a polygonal structure so that the positioning holes 211 on the positioning frames 210 meet the layout of the anchor bolts 500. Then, the position of the fixing block 320 on the positioning frame 210 is adjusted so that the through hole 321 and the positioning hole 211 are aligned. The fixing block 320 is locked and fixed to the positioning frame 210. Next, the polygonal structure composed of positioning frames 210 is connected to the rectangular frame 110 through the tie rod 120. The rectangular frame 110 is fixed to the foundation template through the fixing frame 410 and the support leg 420. The anchor bolts 500 pass through the positioning hole 211 and the through hole 321 in sequence. The position of the anchor bolts 500 is adjusted by adjusting the bolt 330 until the positioning accuracy meets the construction requirements. Finally, concrete is poured. During the pouring process, the positioning frame and fixing device can effectively reduce the possibility of displacement of the anchor bolts 500. After the concrete is poured, each component can be directly disassembled and transported or stored.

[0039] Example 2: Refer to Figure 7 The difference between this embodiment and Embodiment 1 is that each positioning frame 210 has two slidably connected connectors 220. Adjacent positioning frames 210 can be connected end-to-end via connectors 220. Connectors 220 can slide on positioning frames 210, facilitating adjustment of the connection position between positioning frames 210, so that the polygonal structure formed by the positioning frames 210 meets the layout of the anchor bolts 500. Specifically, connector 220 includes a connector body 221 and an overlapping portion 222. The connector body 221 is sleeved on the positioning frame 210, and the overlapping portion 222 is fixedly connected to the connector body 221 and located on the inner side of the polygonal structure. The overlapping portion 222 has multiple second connecting holes 212 along the direction away from the connector body 221. According to the layout of the anchor bolts 500 on different drawings, the connector body 221 is slid to a suitable position and locked with the positioning frame 210. The overlapping portions 222 of adjacent positioning frames 210 overlap together and are then connected by bolts and nuts.

[0040] This application allows for the alignment of appropriate second connecting holes 212 on the overlapping portion 222 of adjacent positioning frames 210 as needed, the insertion of bolts, and the connection and fixation of the positioning frames 210 via nuts. Furthermore, depending on specific project requirements, the overlapping portion 222 can be set with different lengths along the extension direction away from the main body 221 of the connector, and multiple sets of second connecting holes 212 can be provided to adjust the different connection lengths of the positioning frames 210, thereby accommodating more anchor bolt layouts and expanding the applicability of this application.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
