Description

Technical Field

[0001] This utility model relates to the field of anchor bolt technology, and more specifically, to a pre-embedded anchor bolt. Background Technology

[0002] Anchor bolts are connecting elements used in building structures. Before the foundation or concrete structure of a building is poured, anchor bolts are fixed in the concrete. The bolts usually have an exposed threaded portion for connecting supporting structures such as columns, beams, or equipment. The function of anchor bolts is to provide a reliable connection point after the concrete has hardened to support the superstructure or equipment, ensuring the stability and safety of the connection structure and providing support and connection functions.

[0003] Chinese Patent Publication No. CN219606431U discloses a pre-embedded anchor bolt. Four anchor bolt bodies are inserted inside the main body of the anchor bolt, and each anchor bolt body has two threaded fixing caps on its outer wall. The interior of the pre-embedded steel plate also contains four sets of anti-tilting components distributed along a polar axis. This invention utilizes the cooperation between the pre-embedded steel plate, the telescopic frame, and the slider, allowing the telescopic frame to slide out of the pre-embedded steel plate and be mounted at the pit opening. This prevents the anchor bolt from sinking or tilting during pre-embedding. Furthermore, the alignment scale lines make it easier to align the anchor bolt with the center ink line marked on the ground at the pit opening, ensuring accuracy during pre-embedding.

[0004] When using anchor bolts, multiple bolts need to be pre-embedded in the ground together before concrete is poured. This requires that the positions of each anchor bolt be determined in advance before pre-embedding. The traditional positioning method is to pre-position and drill holes in the positioning steel plate, and then insert the anchor bolts one by one into the holes of the steel plate. Therefore, when installing different columns or equipment, different specifications of positioning steel plates need to be customized because the required spacing between anchor bolts is different, which lacks flexibility when the spacing needs to be adjusted.

[0005] Therefore, it is necessary to provide a pre-embedded anchor bolt to solve the above problems. Utility Model Content

[0006] This utility model provides a pre-embedded anchor bolt, which can improve the situation in related technologies where different anchor bolts require different specifications of positioning steel plates when installing different columns or equipment, and lacks flexibility when the spacing needs to be adjusted.

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] Based on this, it can improve the situation in related technologies where, when installing different columns or equipment, different specifications of positioning steel plates are required due to the different spacing between the anchor bolts, resulting in a lack of flexibility when the spacing needs to be adjusted.

[0030] Please see Figures 1-5 An embedded anchor bolt includes four anchor bolts 1 arranged in a rectangular shape. Each anchor bolt 1 has a movable component 2 at its top. Each movable component 2 has a sliding rod 3 on both sides. The bottom of the movable component 2 has two symmetrically arranged sliding rods 4. The outer ends of the sliding rods 3 and 4 are equipped with driving components 5. The sliding rod 3 is located above the sliding rod 4. The driving component 5 includes a bidirectional threaded rod 51 and two driving blocks 52. The bottom ends of the two driving blocks 52 are fixedly connected to threaded sleeves 53. The two threaded sleeves 53 are respectively threaded to both ends of the bidirectional threaded rod 51. The two driving blocks 52 are driven by the bidirectional threaded rod 51 to move in opposite directions.

[0031] The device in this solution is mainly used in construction. Pre-embedded anchor bolts are connecting elements used in building structures. They are typically used to fix the supporting structures of a building, such as columns, beams, or equipment, such as machinery and pipes, into the concrete foundation. Before the building foundation or concrete structure is poured, the pre-embedded anchor bolts are embedded in the concrete to provide a stable connection point. They have strong versatility and can improve the stability and safety of the structure. Anchor bolts are usually used in combination to fix the bottom of the column and other devices.

[0032] This solution uses four anchor bolts 1 combined together, commonly used for smaller posts, such as streetlights and traffic light poles. Because the mounting spaces at the bottom of different posts or poles vary, traditional anchor bolts require customization, lacking flexibility and inconvenient for adjustments during construction. This solution features four anchor bolts 1 with movable components 2 mounted on their tops. Each pair of movable components 2 is connected by two sliding rods 3, while the bottoms of the other two movable components 2 are connected by two sliding rods 4, thus creating a cross-connection between the four movable components 2. The top of the anchor bolt 1 is fixed with a movable block 21 by a nut 6. Fixed blocks 1 22 and 23 are respectively installed on the sides and bottom of the movable block 21. The movable block 21 is installed on the slide rod 1 3 and slide rod 2 4 by the fixed blocks 1 22 and 23 respectively. After rotating the bidirectional threaded rod 51, the two drive blocks 52 drive the movable components 2 to move, thereby adjusting the spacing between the anchor bolts. The two drive components 5 control the translation of the four movable components 2 on the plane, so that the spacing of the anchor bolts can be flexibly adjusted according to the needs, improving the convenience of use.

[0033] Optionally, in some embodiments, please refer to Figures 1-5 The movable component 2 includes a movable block 21, with fixed blocks 22 fixedly connected to both sides of the movable block 21, and two fixed blocks 23 symmetrically distributed fixedly connected to the bottom of the movable block 21. The outer end of the movable block 21 has mounting holes that are compatible with the anchor bolts 1.

[0034] Slide rod 3 passes through fixed block 22, slide rod 4 passes through fixed block 23, movable block 21 slides on the outer end of slide rod 3 through fixed block 22, and movable block 21 slides on the outer end of slide rod 4 through fixed block 23.

[0035] In this design, the movable block 21 has a mounting hole near the center of its outer end, through which the bolt column 11 can pass. Fixing blocks 1 22 are fixed on both sides of the movable block 21. Fixing blocks 1 22 are used to fit around the outer end of the sliding rod 1 3, allowing the movable block 21 to slide along the sliding rod 1 3. At the bottom of the movable block 21, two fixing blocks 23 are fixed. Fixing blocks 23 are fitted around the outer end of the sliding rod 2 4, allowing the movable block 21 to slide along the sliding rod 2 4 as well. The sliding rod 1 3 and the sliding rod 2 4 are perpendicular to each other, forming the X and Y axes in the coordinate system, so that each movable block 21 can move along the X and Y axes.

[0036] Optionally, in some embodiments, please refer to Figure 4 and Figure 5 The drive block 52 has two symmetrically distributed through holes 55 at its outer end, which are adapted to slide rod 3 and slide rod 4.

[0037] The drive block 52 is fixedly installed on the outer end of the slide bar 3, and the drive block 52 is also fixedly installed on the outer end of the slide bar 4. One end of the bidirectional threaded rod 51 is fixedly connected to the rotating head 54.

[0038] In this design, two drive components 5 are configured. One controls the movement of four movable components 2 along the X-axis, and the other controls the movement of four movable components 2 along the Y-axis. A pair of oppositely oriented threads are provided on the bidirectional threaded rod 51. A rotating head 54 is fixed to one end of the bidirectional threaded rod 51. The user can drive the bidirectional threaded rod 51 to rotate using a wrench or power tool. Simultaneously, a threaded sleeve 53 is fixed to the bottom end of each drive block 52. The threaded sleeve 53 is adapted to and threadedly connected to the bidirectional threaded rod 51. Therefore, when the bidirectional threaded rod 51 rotates, it causes the two drive blocks 52 to move in opposite directions, either moving closer to or further away from each other. Two through holes 55 are provided at the outer end of each drive block 52. These through holes 55 are adapted to slide rod 1 3 and slide rod 2 4. There are four slide rods each, and each drive block 52 is fixed with two slide rods 1 3 or slide rod 2 4 through the through holes 55. The four drive blocks 52... Slide rod 3 and slide rod 4 can be fixed in place. When one of the bidirectional threaded rods 51 is rotated, two of the drive blocks 52 will move. Since slide rod 3 or slide rod 4 is fixedly connected to it, the four slide rods 3 can be moved by the two drive blocks 52. Since the movable block 21 can slide on slide rod 3 and slide rod 4 through fixed block 22 and fixed block 23, rotating one of the bidirectional threaded rods 51 can control the four movable components 2 to move in one direction. When the other bidirectional threaded rod 51 is rotated, the four movable components 2 will be driven to move in another direction by the same principle. Thus, the spacing between the four movable components 2 can be adjusted by the two drive components 5. The anchor bolt 1 is fixed to the movable block 21 by the nut 6, thus achieving the purpose of adjusting the spacing between the anchor bolts 1, making it more flexible in use.

[0039] Optionally, in some embodiments, please refer to Figure 1 and Figure 2 Anchor bolt 1 includes bolt body 11, bolt end 12 is fixedly connected to the top of bolt body 11, bolt end 12 is threaded at the outer end, bolt end 12 passes through the mounting hole of movable block 21, and two nuts 6 are threadedly connected to the outer end of bolt end 12, the two nuts 6 are located on the upper and lower sides of movable block 21 respectively.

[0040] A hook 13 is fixedly connected to the bottom end of the bolt column 11. The hook 13 is U-shaped. Multiple anti-torsion rings 14 are fixedly connected to the outer ends of both the bolt column 11 and the hook 13. Multiple anti-torsion rings 15 are fixedly connected to the outer ends of the hook 13.

[0041] The anchor bolt 1 in this design mainly consists of a bolt body 11, a bolt end 12, and a hook 13. The bolt body 11 is fixed to the bottom of the bolt end 12, which has threads for threaded connection with nuts 6. Two nuts 6 can then fix the bolt end 12 into the mounting hole of the movable block 21. The hook 13 is fixed to the bottom of the bolt body 11 and is U-shaped. This design primarily increases friction with the concrete. When the device is embedded in the concrete, the curved shape of the hook 13 increases the contact area with the concrete. The contact area is increased by multiple anti-torsion rings 14 fixed on the bolt column 11 and multiple anti-torsion rings 14 fixed on the vertical end of the hook 13. When the anchor bolt 1 is embedded in the concrete, the anti-torsion rings 14 can further increase the contact area, thereby increasing the pull-out resistance of the anchor bolt 1. The anti-torsion ring 15 is fixed at the lowest point of the recess of the hook 13. The anti-torsion ring 15 is installed vertically, while the anti-torsion ring 14 is installed horizontally. The vertical installation of the anti-torsion ring 15 can increase the horizontal shear resistance of the anchor bolt 1, further improving its installation firmness.

[0042] Working principle: When using this device, the spacing between the four anchor bolts 1 needs to be adjusted first. The outer end of the movable block 21 has a mounting hole near the center for mounting the bolt column 11. The first fixed block 22 is used to fit on the outer end of the first sliding rod 3, and the second fixed block 23 is fitted on the outer end of the second sliding rod 4. They are mutually perpendicular, forming the X and Y axes in the coordinate system, so that each movable block 21 can move along the X and Y axes. Rotating one of the bidirectional threaded rods 51 will cause two of the driving blocks 52 to move, driving the four sliding rods 3 or 4 to move. When the other bidirectional threaded rod 51 is rotated, the four movable components 2 will be driven to move in another direction through the same principle. Thus, the spacing between the four movable components 2 can be adjusted through the two driving components 5, thereby achieving the purpose of adjusting the spacing between the anchor bolts 1, making it more flexible in use.
