Description

Technical Field

[0001] This application relates to the field of anchor bolt installation technology, and in particular to an anchor bolt positioning and balancing adjustment device. Background Technology

[0002] In traditional pole foundation construction, the pre-embedding accuracy of anchor bolts directly affects the installation quality of the superstructure. Currently, the industry commonly adopts the method of independently installing the reinforcing cage and then welding the anchor bolts on site. However, due to the influence of confined space conditions, the reinforcing cage is not easy to fix during installation, and the quality of anchor bolt welding is also difficult to control. Problems such as bolt misalignment and verticality discrepancies are prone to occur during pole installation, which affects the subsequent installation of the pole. Utility Model Content

[0003] To achieve precise installation of anchor bolts, this application provides an anchor bolt positioning and balancing adjustment device.

[0004] Firstly, this application provides an anchor bolt positioning and balancing adjustment device, which adopts the following technical solution: An anchor bolt positioning and balancing adjustment device includes a support frame, two of which are arranged at intervals. A crossbar is mounted on the support frame; The connecting components are provided in two sets, and the two sets of connecting components are arranged at intervals along the length direction of the crossbar. The connecting components are used to connect the anchor bolts to the crossbar. The connecting assembly includes a connecting frame and a connecting rod. Both ends of the connecting frame are provided with threaded holes. One end of the connecting frame is used for threaded connection with an anchor bolt, and the other end of the connecting frame is used for threaded connection with the connecting rod. The end of the connecting rod away from the connecting frame is connected to the crossbar. The crossbar is slidably connected to the support frame along its own length direction, and a first locking assembly is provided between the crossbar and the support frame for locking the crossbar to the support frame; The connecting rod is slidably connected to the crossbar, and the sliding direction of the connecting rod is perpendicular to the length direction of the crossbar. The crossbar is provided with a second locking assembly for locking the connecting rod to the crossbar.

[0005] By adopting the above technical solution, this application achieves position adjustment in two vertical directions in the horizontal plane by setting a sliding crossbar and connecting rod and equipping it with a corresponding locking component; at the same time, by setting a connecting component, the height and tilt angle of the anchor bolts connected to it can be adjusted, which can solve the problem of anchor bolts being prone to displacement and verticality difference after installation as mentioned in the background art.

[0006] Optionally, the connecting rod is a screw rod, one end of which is threaded to the connecting frame, and the other end of which is threaded onto the crossbar. A limit nut is threaded to one end of the connecting rod that extends out of the crossbar.

[0007] By adopting the above technical solution, the connecting rod is designed as a screw and used with a limit nut to form a simple and reliable spiral lifting mechanism. By rotating the limit nut, the operator can easily control the axial extension length of the connecting rod, thereby making stable and precise vertical height adjustment of the connecting components and anchor bolts, improving the accuracy and convenience of the adjustment process.

[0008] Optionally, the support frame is a triangular adjustable bracket that can be raised and lowered.

[0009] By adopting the above technical solution and using a triangular adjustment bracket as a support structure, a wide and stable support base can be provided for the entire adjustment device, ensuring that the device itself will not easily shake or overturn when adjusting under heavy loads, thereby improving the safety and reliability of the entire adjustment system. Since the height of the movable end of the triangular adjustment bracket is adjustable, it is convenient to adjust both ends of the crossbar, thereby achieving the initial leveling of the crossbar.

[0010] Optionally, the first locking assembly includes a collar and a locking bolt. The collar is connected to the support frame, the crossbar slides through the collar, and the locking bolt is threaded onto the collar. The end of the locking bolt is used to abut against the crossbar.

[0011] By adopting the above technical solution, when the locking bolt is loosened, the crossbar can slide smoothly in the collar; after reaching the predetermined position, tightening the locking bolt can apply pressure at its end to firmly position the crossbar, thus enabling rapid adjustment and reliable locking of the horizontal position of the crossbar.

[0012] Optionally, the second locking assembly includes a connecting block and a locking screw. The connecting block is connected to the crossbar. There are two connecting blocks, which are respectively located on both sides of the connecting rod. The locking screw is threaded to the connecting block, and the end of the locking screw is used to abut against the connecting rod.

[0013] By adopting the above technical solution, the second locking assembly can effectively clamp the connecting rod laterally through the cooperation of the connecting blocks on both sides and the locking screw. When it is necessary to adjust the position of the connection point in the direction perpendicular to the length of the crossbar, simply loosen the locking screw, adjust it, and then tighten it again to complete the fixation, providing a reliable locking guarantee for adjustment in the other direction of the horizontal plane.

[0014] Optionally, the crossbar has a rectangular cross-section, and connecting discs are fitted on the outer walls of both ends of the crossbar. The connecting discs are circular and are rotatably slidably fitted into the collar.

[0015] By adopting the above technical solution, the crossbar with rectangular cross section has good bending resistance and is not easy to bend and deform under load; the circular connecting discs that can rotate at both ends make the crossbar equivalent to a pivot that can rotate around its own axis when it is not locked. When there is misalignment between the suspended anchor bolts and the steel cage, the rotation characteristics of the connecting discs allow the weight to swing naturally to a balanced vertical state under the action of gravity, providing a good initial condition for subsequent precise verticality adjustment.

[0016] Secondly, this application provides a construction system, which adopts the following technical solution: A construction system includes any of the above-described anchor bolt positioning and balancing adjustment devices, and further includes anchor bolts, a fixing plate, and a reinforcing cage. The anchor bolts are fixedly mounted on the fixing plate, and the anchor bolts are threaded with positioning nuts for abutting against the fixing plate. The reinforcing cage is connected to the anchor bolts.

[0017] By adopting the above technical solution, the construction system pre-assembles the anchor bolts, fixing plates and steel cages into an integrated assembly, avoiding the difficulty of welding in narrow pile holes; then, the above-mentioned adjustment device is used to hoist and adjust the assembly as a whole, which helps to improve construction efficiency and installation accuracy.

[0018] Optionally, the anchor bolts are welded to the reinforcing cage for fixation.

[0019] By adopting the above technical solution, the anchor bolts and the steel cage are firmly connected by welding, ensuring that there is no relative displacement between the two during handling, hoisting and adjustment, forming a stable structural whole, which facilitates precise positioning in the future.

[0020] Optionally, a bubble level is provided on the fixing plate.

[0021] By adopting the above technical solution, a real-time and intuitive level status indicator is provided for on-site operators. During the adjustment process, operators can directly refer to the status of the bubble level to judge whether the fixing plate is level, thereby ensuring that all anchor bolts are in a good vertical state, which helps to simplify the measurement steps and improve the leveling efficiency.

[0022] Optionally, multiple anchor bolts are provided on the fixing plate, and the multiple anchor bolts are arranged in a circumferential array. The anchor bolts at both ends of the same diameter direction of the fixing plate are exposed, and the outer side of the remaining anchor bolts is wrapped with a protective film.

[0023] By adopting the above technical solution, only the two anchor bolts used to connect the adjustment device are left exposed, which facilitates the connection operation with the connecting frame; while the threads of the remaining anchor bolts are wrapped with protective film, which can effectively prevent mud, concrete and other debris from contaminating the threads during construction, ensuring that the nuts can be tightened smoothly when the uprights are installed later, thereby improving the construction quality.

[0024] In summary, this application includes the following beneficial technical effects: 1. The anchor bolts are hoisted onto the crossbar, and then the state of the anchor bolts can be easily adjusted by coarse adjustment of the crossbar and fine adjustment of the anchor bolts, thus reducing the possibility of the anchor bolts shifting or tilting after installation.

[0025] 2. This device can be disassembled and is easy to carry. After on-site assembly, it can adapt to various terrains and has a wide range of applications. The components of this device can be made using on-site components, which can reuse waste materials, reduce material waste, and lower the cost of using the device. Attached Figure Description

[0028] The following combination Figures 1-3 This application will be described in further detail.

[0029] This application discloses an anchor bolt positioning and balancing adjustment device. (Refer to...) Figure 1The anchor bolt 8 positioning and balancing adjustment device includes a support frame 1, a crossbar 2, and a connecting assembly 3. Two support frames 1 are provided and arranged at intervals. Both support frames 1 are triangular adjustment brackets for easy adjustment of the height of the free end; the triangular adjustment bracket is a prior art feature, and its specific structure will not be described in detail here. The two support frames 1 are used to install on both sides of the reserved pile hole, and the reserved pile hole is located on the line connecting the two support frames 1.

[0030] A crossbar 2 slides between two support frames 1, each of which is equipped with a first locking assembly 4 for locking the crossbar 2. The first locking assembly 4 includes a collar 41 and a locking bolt 42. The collar 41 is fixedly installed on the movable end of the support frame 1 and is fitted onto the outer side of the crossbar 2. A vertically oriented threaded hole is formed at the top of the collar 41, and the locking bolt 42 is threaded into this hole. One end of the locking bolt 42 protruding from the threaded hole abuts against the top of the crossbar 2. Therefore, tightening the locking bolt 42 fixes the end of the crossbar 2 to the support frame 1.

[0031] The connecting component 3 is located in the middle of the crossbar 2. The crossbar 2 is fitted with anchor bolts 8 via the connecting component 3, which facilitates subsequent adjustment of the anchor bolts 8. There are two sets of connecting components 3, which are arranged at intervals along the length of the crossbar 2.

[0032] Reference Figure 1 and Figure 2 Each connecting assembly 3 includes a connecting frame 31 and a connecting rod 32. The connecting frame 31 includes two parallel support rods spaced apart and nuts welded to the upper and lower ends of the support rods. The support rods can be directly replaced with steel bars, thus facilitating the fabrication of the connecting frame 31 using on-site materials and helping to reduce costs. The bottom end of the connecting frame 31 is threaded to the top end of the anchor bolt 8, and the top end of the connecting frame 31 is threaded to the bottom end of the connecting rod 32. The connecting rod 32 is a vertically arranged screw rod; the top end of the connecting rod 32 protrudes from the top wall of the crossbar 2, and the end of the connecting rod 32 protruding from the crossbar 2 is threaded to a limit nut 6. Therefore, the anchor bolt 8 can be hung on the crossbar 2 through the connecting assembly 3. Since the top height of the support frame 1 is adjustable, the crossbar 2 can be initially leveled by adjusting the support frames 1 at both ends of the crossbar 2. Then, by rotating the limit nut 6, the hanging height of the anchor bolt 8 can be further adjusted, thereby further adjusting the state of the anchor bolt 8 to enhance the adjustment effect and improve the verticality of the anchor bolt 8.

[0033] Reference Figure 3In addition, to facilitate adjustment of the installation position of the anchor bolts 8, the crossbar 2 is a square bar with vertically penetrating holes 21. The length of the holes 21 is along the width of the crossbar 2. There are two holes 21, each corresponding to one of the two connecting rods 32. The connecting rods 32 pass through the holes 21, so the installation position of the connecting rods 32 can be adjusted not only vertically but also along the width of the crossbar 2. To facilitate locking the connecting rods 32, the crossbar 2 is provided with a second locking assembly 5. There are two sets of the second locking assembly 5, each set corresponding to one connecting rod 32.

[0034] The second locking assembly 5 includes connecting blocks 51 and locking screws 52. Two connecting blocks 51 are provided, each fixedly connected to the top wall of the crossbar 2. The two connecting blocks 51 are spaced apart along the width direction of the crossbar 2, and the connecting rod 32 is located between the two connecting blocks 51. Two locking screws 52 are provided, each corresponding to one of the two connecting blocks 51. Each locking screw 52 is threaded onto its corresponding connecting block 51. Each locking screw 52 has a protrusion at its far end to facilitate rotation. Therefore, after sliding the connecting rod 32 laterally to the desired position, simply rotating the locking screws 52 on both sides will cause the ends of both locking screws 52 to abut against the connecting rod 32, thus restricting the lateral movement of the connecting rod 32 relative to the crossbar 2 and achieving lateral locking of the connecting rod 32.

[0035] Furthermore, an abutment block 521 can be rotatably connected to the end of the locking screw 52. The abutment block 521 is a rectangular block, and its bottom wall abuts against the top wall of the crossbar 2, thus restricting the rotation of the abutment block 521. An arc-shaped abutment groove adapted to the connecting rod 32 is also provided on the side of the abutment block 521 near the connecting rod 32. When the locking screw 52 rotates, it can move axially, and the locking screw 52 drives the abutment block 521 to move together until the abutment block 521 abuts against the top of the connecting rod 32, thereby completing the locking of the connecting rod 32. The setting of the abutment block 521 helps to increase the abutment area, thereby enhancing the locking and limiting effect on the connecting rod 32. The abutment block 521 has a relief groove on the side near the connecting rod 32. Therefore, when the abutment block 521 is pressed against the connecting rod 32, the inner wall of the relief groove and the limiting nut 6 are spaced apart. Thus, the limiting nut 6 does not easily affect the pressing process of the abutment block 521 against the connecting rod 32.

[0036] Reference Figure 1In addition, connecting discs 7 are fixedly fitted on the outer walls of both ends of the crossbar 2. Each connecting disc 7 is a circular disc, and each connecting disc 7 corresponds to a collar 41. The outer diameter of the connecting disc 7 is adapted to the inner diameter of the collar 41, and the axial length of the connecting disc 7 is greater than the axial length of the collar 41. Therefore, after the anchor bolts 8 and the reinforcing cage 10 are hung on the crossbar 2, which is inserted through the two collars 41, it can swing under the action of the hanging weight, so that the anchor bolts 8 hung on the crossbar 2 are initially adjusted to a vertical state to ensure the subsequent adjustment accuracy.

[0037] The implementation principle of the anchor bolt positioning and balancing adjustment device in this application embodiment is as follows: When pre-embedding the anchor bolt 8, firstly, two triangular adjustment brackets are placed on the stable ground on both sides of the pile hole; then, the anchor bolt 8, fixing plate 9, and reinforcing cage 10 are connected and fixed to form a combined body. Next, the top of the anchor bolt 8 is connected to the crossbar 2 through the connecting component 3, and then the crossbar 2 is lifted by external hoisting equipment, so that the crossbar 2 is in a horizontal state and the reinforcing cage 10 and anchor bolt 8 are in a vertical state; then, the reinforcing cage 10 is moved above the pile hole and lowered into the pile hole.

[0038] The collars 41 on both sides of the support frame 1 are fitted onto both ends of the crossbar 2, thus supporting the crossbar 2. Then, by adjusting the two support frames 1, the crossbar 2 can be initially leveled. Next, by rotating the limiting nut 6 at the top of one of the connecting rods 32, the anchor bolt 8 corresponding to that connecting rod 32 can be raised or lowered, thereby further adjusting and improving the verticality of the anchor bolt 8. Then, by moving along the length and width of the crossbar 2, the installation positions of the anchor bolt 8 and the reinforcing cage 10 can be adjusted, ensuring precise alignment of the reinforcing cage 10 with the pile hole, thus accurately moving the anchor bolt 8 to the required position. Subsequently, concrete is poured into the pile hole, and after the concrete solidifies, the position of the anchor bolt 8 is fixed, completing the installation process of the anchor bolt 8. Finally, the connecting frame 31 is disassembled from the top of the anchor bolt 8, and the adjusting device is removed; it can be reused later.

[0039] Reference Figure 2 This embodiment also discloses a construction system, including the above-mentioned anchor bolt positioning and balancing adjustment device, and also includes a pre-assembled assembly, which includes a cylindrical steel cage 10, a circular steel fixing plate 9 fixed to the top of the steel cage 10, and a plurality of anchor bolts 8.

[0040] Multiple anchor bolts 8 are evenly arranged in a circumferential array on the fixing plate 9, with the top of the anchor bolt 8 protruding 5-7 cm from the fixing plate 9. Each anchor bolt 8 is threaded with a positioning nut 11, which is located below the fixing plate 9 and welded to the fixing plate 9, thus fixing the anchor bolt 8 and the fixing plate 9 together. The portions of all anchor bolts 8 below the fixing plate 9 are welded to the reinforcing cage 10 with reinforcing bars, thus forming a stable assembly of the anchor bolts 8, fixing plate 9, and reinforcing cage 10.

[0041] To facilitate subsequent installation and adjustment, a bubble level is attached to the center of the upper surface of the fixing plate 9. In addition, among these anchor bolts 8, the two anchor bolts 8 located at both ends of the same diameter direction of the fixing plate 9 have exposed threads, which are used as lifting points for connection with the connecting bracket 31; the threaded portions of the remaining anchor bolts 8 are pre-wrapped with plastic protective film to prevent damage or blockage of the bolt threads during construction.

[0042] The implementation principle of the construction system in this embodiment is as follows: First, the assembly and welding of the above-mentioned assembly are completed on the ground. Then, the connecting frame 31 and the anchor bolt 8 are threaded together at one end of the fixed plate 9, so that the two anchor bolts 8 are inserted into the connecting frame 31 by approximately the same length. Next, the connecting rod 32 is inserted into the through hole 21 on the crossbar 2, the bottom end of the connecting rod 32 is threaded to the connecting frame 31, and the top end of the connecting rod 32 is screwed into the limiting nut 6, which abuts against the top wall of the crossbar 2. Then, the crossbar 2 is lifted by external hoisting equipment, and the crossbar 2 is lifted upward by slings, so that the crossbar 2 is in a horizontal state, the reinforcing cage 10 and the anchor bolt 8 are in a roughly vertical state. Then, the crossbar 2 is moved to move the reinforcing cage 10, and the reinforcing cage 10 is steadily placed into the pile hole.

[0043] Then, support frames 1 are placed on both sides of the pile hole, with the line connecting the two support frames 1 passing through the center of the pile hole. The two ends of the crossbar 2 are respectively inserted into the collars 41 on the two support frames 1. The external hoisting equipment releases its grip on the crossbar 2. At this point, the crossbar 2 is supported by the support frames 1, and the assembly is hung in the middle of the crossbar 2. Next, the operator adjusts the height of the support frames 1 at both ends to gradually level the two ends of the crossbar 2. Then, by rotating the limiting nut 6 at the top of one of the connecting rods 32, or by rotating the limiting nuts 6 at the top of both connecting rods 32 respectively, the ends of the assembly are raised and lowered accordingly, thereby readjusting the state of the anchor bolts 8 until the bubble in the bubble level on the fixing plate 9 is centered. Finally, by adjusting the assembly in two directions, the assembly consisting of the reinforcing cage 10 and the anchor bolts 8 is precisely positioned at the center of the pile hole. Then, it is locked by the first locking component 4 and the second locking component 5, so that the anchor bolts 8 can be better maintained in this state.

[0044] Next, the middle part of the reinforcing cage 10 is fixed with reinforcing bars, and then concrete is poured into the pile hole. After the concrete solidifies, the position of the anchor bolt 8 can be fixed. At this time, the connection between the connecting frame 31 and the anchor bolt 8 can be disassembled, and then the adjusting device can be removed. The above method can improve the installation accuracy of the anchor bolt 8, so as to facilitate the subsequent installation of the upright.

[0045] The above are optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
