Description

Technical Field

[0001] This invention relates to the field of pull-out anchor manufacturing, specifically to a pull-out anchor and its application method. Background Technology

[0002] Pull-out anchors, also known as inclined tension anchors, are installed in layers according to the depth of earthwork excavation to reinforce the walls around the foundation pit. Anchors are generally drilled, laid, and concrete poured at a downward angle of 10-15 degrees. They are a type of support device used to reinforce the strata to prevent deformation, collapse, or instability that could endanger safety.

[0003] Existing pull-out anchors are typically small, resulting in a small contact area with the ground and the inner wall of the opening, which leads to low stability and affects the stability of the formation. Therefore, those skilled in the art provide a pull-out anchor and its usage method to solve the problems mentioned in the background art. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an anti-pull-out anchor bolt and its application method, solving the problems of small contact area and low stability of the fixed strata.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an anti-pull-out anchor rod, comprising a fixed screw rod, wherein a pressing plate is threadedly provided on the upper end of the screw rod body, and stabilizing mechanisms are fixedly provided on both sides and front and rear of the upper end of the pressing plate, each of the four stabilizing mechanisms comprising an upper telescopic rod, a fixing mechanism is fixedly provided on the upper end of the opposite side of the four stabilizing mechanisms, a connecting plate is fixedly provided on the upper end of the opposite side of the four stabilizing mechanisms, a first spring is embedded in the upper end of the opposite side of the four connecting plates, an inclined block is fixedly provided on the upper end of each of the four first springs, a release button is movably provided between the upper ends of the four inclined blocks, and a connecting block is slidably provided on the outer surface of the release button;

[0008] A circular blade is fixedly installed at the lower end of the extrusion disc. Multiple connecting plates are fixedly installed on both sides and at the front and rear ends of the fixed screw. A support frame is fixedly installed at the lower end of the fixed screw. Support mechanisms are fixedly installed on both sides and at the front and rear ends of the support frame. The support mechanism includes a stabilizing plate.

[0009] Each of the four upper telescopic rods has a first rotating shaft fixedly installed at its lower end, and each of the four first rotating shafts has a lower telescopic rod fixedly installed at its lower end. Each of the four lower telescopic rods is fixedly installed at the upper end of the extrusion disc.

[0010] All four fixing mechanisms include hollow columns, and each of the four hollow columns has a sliding groove in the middle of its interior. An impact steel head is fixedly installed on opposite sides of each of the four hollow columns.

[0011] The four stabilizing plates have multiple rotating slots through both sides. The upper part of each of the multiple rotating slots is rotatably provided with a second rotating shaft. A stabilizing pin is fixedly provided on one side of each of the multiple second rotating shafts near the top.

[0012] A pulling block is fixedly installed on one side of each of the multiple second rotating shafts near the bottom. A pulling rope is fixedly installed at the lower end of each of the multiple pulling blocks. The other end of each of the multiple pulling ropes is fixedly connected to a multiple connecting plate. The outer surface of each of the multiple support mechanisms is sprayed with anti-corrosion paint.

[0013] During the rotation, the circular blade will gradually descend. As the extrusion plate descends, it will gradually push the support mechanism outward, eventually fitting it against the inner wall of the hole. As the support mechanism is stretched open, the connecting plate will pull the stabilizing pin downward to rotate, eventually nailing it into the inner wall of the hole in a horizontal position. After being pulled, the connecting plate will be cut off by the circular blade.

[0014] Preferably, each of the four sliding grooves has a hammer block slidably disposed inside, and each of the four hammer blocks is fixedly disposed between itself and one side of the inner surface of the four hollow columns.

[0015] A method for using an anti-pull-out anchor bolt includes the following steps:

[0016] S1. Drilling machine for punching holes

[0017] First, use a drilling machine to drill holes at the locations where pull-out anchors need to be installed. The hole diameter should be slightly larger than the diameter of the extrusion plate, and the hole height should be slightly larger than the height of the fixing screw.

[0018] S2. Adjust positioning

[0019] Place the pull-out anchor rod into the drilled hole and adjust its position so that the pull-out anchor rod is in the exact center of the hole;

[0020] S3. Rotational Fixation

[0021] Rotate the stabilizing mechanism above to drive the extrusion disc to rotate on the fixed lead screw;

[0022] S4. Enhance stability mechanism

[0023] Pull the stabilizing mechanism to extend the upper telescopic rod upwards until the first pivot is exposed, then press the release button to remove the connecting block from the connecting plate;

[0024] S5. Lower the fixing mechanism

[0025] Extend each of the four upper telescopic rods outwards. During the extension process, apply a downward force to the upper telescopic rods to make the fixing mechanism descend rapidly. After the impact steel head contacts the ground, the hammer block applies another force, allowing the fixing mechanism to insert into the ground. At this point, the installation is complete.

[0026] (III) Beneficial Effects

[0027] This invention provides an anti-pull-out anchor bolt and its method of use. It has the following beneficial effects:

[0028] 1. This invention provides an anti-pull-out anchor rod and its usage method. The anti-pull-out anchor rod, through the support mechanism set below, can be pressed against the inner wall of the opening during the installation process, and at the same time, the stabilizing pin is inserted, so that the anti-pull-out anchor rod can be more firmly installed in the ground and will not easily fall off, greatly improving the stability of the stratum.

[0029] 2. This invention provides an anti-pull-out anchor rod and its usage method. After the support mechanism is fixed in the hole, the upper stabilizing mechanism of the anti-pull-out anchor rod can be unfolded and the fixing mechanism can be lowered, so that the fixing mechanism is fixed on the periphery of the opening, increasing the contact area between the anti-pull-out anchor rod and the ground, and greatly improving the stability.

[0030] 3. This invention provides an anti-pull-out anchor rod and its usage method. The anti-pull-out anchor rod is fixed in the ground by a support mechanism. The fixing mechanism consists of a stabilizing plate, which is sprayed with anti-corrosion paint and is mostly made of stainless steel, which greatly improves the strength and service life of the anti-pull-out anchor rod.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example:

[0041] like Figure 1-7 As shown, this embodiment of the invention provides an anti-pull-out anchor rod, including a fixing screw 17. The upper end of the fixing screw 17 is threaded with a compression plate 1. Stability mechanisms 6 are fixedly installed on both sides and front and back of the upper end of the compression plate 1. The stability mechanisms 6 can be unfolded after the support mechanism 5 is fixed in the hole, so that the fixing mechanism 7 can be fixed in the ground. Each of the four stability mechanisms 6 includes an upper telescopic rod 8. The upper end of the opposite side of the four stability mechanisms 6 is fixedly installed with a fixing mechanism 7. The upper end of the opposite side of the four stability mechanisms 6 is fixedly installed with a connecting plate 18. The upper end of the opposite side of the four connecting plates 18 is embedded with a first spring 21. The upper end of the four first springs 21 is fixedly installed with an inclined block 20. The upper ends of the four inclined blocks 20 are movably installed with a release button 19. The outer surface of the release button 19 is slidably installed with a connecting block 27, which can fix the stability mechanism 6 into one piece during rotation, so as to facilitate rotation. When it needs to be fixed in the ground, it can be opened.

[0042] A circular blade 2 is fixedly installed at the lower end of the extrusion plate 1, which can cut the connecting plate 3 below. Multiple connecting plates 3 are fixedly installed on both sides and the front and rear ends of the fixed screw 17. A support frame 4 is fixedly installed at the lower end of the fixed screw 17. Support mechanisms 5 are fixedly installed on both sides and the front and rear ends of the support frame 4. The support mechanism 5 includes a stabilizing plate 11.

[0043] Each of the four upper telescopic rods 8 has a first rotating shaft 9 fixedly installed at its lower end, and each of the four first rotating shafts 9 has a lower telescopic rod 10 fixedly installed at its lower end. Each of the four lower telescopic rods 10 is fixedly installed at the upper end of the extrusion plate 1, so that the stabilizing mechanism 6 can extend after entering the ground. Each of the four fixing mechanisms 7 includes a hollow column 23. Each of the four hollow columns 23 has a sliding groove 24 opened in the middle of its interior. Each of the four hollow columns 23 has an impact steel head 22 fixedly installed on opposite sides. Each of the four sliding grooves 24 has a hammer block 25 slidably installed inside it. Each of the four hammer blocks 25 has a second spring 26 fixedly installed between it and one side of the inner surface of each of the four hollow columns 23. After the impact steel head 22 contacts the ground, the fixing mechanism 7 provides another force through the hammer block 25, so that the fixing mechanism 7 can better insert into the ground.

[0044] Multiple rotating slots 14 are provided through both sides of the four stabilizing plates 11. A second rotating shaft 13 is rotatably installed at the upper end of each of the multiple rotating slots 14. A stabilizing pin 12 is fixedly installed on the upper side of each of the multiple second rotating shafts 13. A pulling block 16 is fixedly installed on the lower side of each of the multiple second rotating shafts 13. A pulling rope 15 is fixedly installed at the lower end of each of the multiple pulling blocks 16. The other end of each pulling rope 15 is fixedly connected to multiple connecting plates 3. The outer surface of the multiple support mechanisms 5 is sprayed with anti-corrosion paint 28. When the support mechanism 5 is stretched open, the connecting plate 3 will pull the stabilizing pin 12 to rotate downwards, and finally nail it into the inner wall of the hole in a horizontal position. After being pulled, the connecting plate 3 will be cut off by the circular blade 2.

[0045] A method for using an anti-pull-out anchor bolt includes the following steps:

[0046] S1. Drilling machine for punching holes

[0047] First, use a drilling machine to drill holes at the locations where pull-out anchors need to be installed. The hole diameter is slightly larger than the diameter of the extrusion plate 1, and the hole height is slightly larger than the height of the fixing screw 17, so that the pull-out anchor can just enter the hole.

[0048] S2. Adjust positioning

[0049] Place the pull-out anchor rod in the drilled hole and adjust its position so that the pull-out anchor rod is in the exact center of the hole, so that the stabilizing mechanism 6 can be better fixed in the hole;

[0050] S3. Rotational Fixation

[0051] Rotate the upper stabilizing mechanism 6 to drive the extrusion disc 1 to rotate on the fixed screw 17. During the rotation, the circular blade 2 will gradually descend. As the extrusion disc 1 descends, it will gradually push the support mechanism 5 outward, eventually fitting it against the inner wall of the hole.

[0052] S4. Enhance stability mechanism

[0053] Pull the stabilizing mechanism 6 to extend the upper telescopic rod 8 upward until the first rotating shaft 9 is exposed. Then press the release button 19 to remove the connecting block 27 from the connecting plate 18.

[0054] S5. Lower the fixing mechanism

[0055] Extend the four upper telescopic rods 8 outwards respectively. During the extension process, a downward force is applied to the upper telescopic rods 8 to make the fixing mechanism 7 descend quickly. After the impact steel head 22 contacts the ground, the hammer block 25 provides another force, allowing the fixing mechanism 7 to be inserted into the ground. At this point, the installation is complete.

[0056] During the process of the support mechanism 5 being stretched open, the connecting plate 3 will pull the stabilizing pin 12 to rotate downwards, eventually nailing it into the inner wall of the hole in a horizontal position, and the connecting plate 3 will be cut off by the circular blade 2 after being pulled.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
