Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fasteners, and specifically relates to a ground anchor bolt. Background Art
[0002] In the fields of civil engineering, construction engineering, temporary facility construction, and outdoor activities, as an important fixing device, ground anchor bolts are widely used for the stability and fixation of the ground. The structural design of traditional ground anchor bolts is often relatively simple, lacking an optimized insertion and fixation mechanism, resulting in an unsatisfactory fixation effect in the soil. Especially in soft soil or sandy soil, loosening or pulling out is more likely to occur.
[0003] In addition, there are also certain difficulties in removing traditional ground anchor bolts. Due to the large frictional force between the soil and the ground anchor bolts, large machinery or tools are often required to pull them out, which not only increases the working difficulty and cost, but also may cause damage to the surrounding environment.
[0004] Therefore, there is an urgent need in the market for a ground anchor bolt with a reasonable structure, high strength, good corrosion resistance, easy insertion into the soil, excellent fixation effect, and convenient removal. Content of the Utility Model
[0005] In order to solve the problems of the prior art, the utility model provides a ground anchor bolt. By optimizing the structural design and selecting high-performance materials, it aims to solve the problems existing in traditional ground anchor bolts and improve the service performance and efficiency of the ground anchor bolt.
[0006] To solve the above technical problems, the utility model is realized through the following technical solutions: A ground anchor bolt includes an anchor head, an anchor body, an anchor rod, and an anchor rope. A first hinge is fixedly connected to the top end of the anchor head, and the top end of the first hinge is fixedly connected to the bottom end of the anchor body. An anchor head concave head is provided at the top end of the anchor head, and an anchor body convex head is provided at the bottom end of the anchor body. The inner wall of the anchor head concave head matches the outer wall of the anchor body convex head for plug-in connection.
[0007] A second hinge is fixedly connected to the top end of the anchor body, and the top end of the second hinge is fixedly connected to the anchor rod. An anchor body concave head is provided at the top end of the anchor body, and an anchor rod convex head is provided at the bottom end of the anchor rod. The outer wall of the anchor rod convex head matches the inner wall of the anchor body concave head for plug-in connection.
[0008] A first limiting hole is provided inside the anchor rod, and the anchor rope is slidably connected to the inside of the first limiting hole. A second limiting hole is provided inside the anchor body, and the anchor rope is slidably connected to the second limiting hole. One end of the anchor rope is fixedly connected to the anchor head, and the anchor rope sequentially passes through the second limiting hole and the first limiting hole for driving the anchor head, the anchor body, and the anchor rod to be inserted into each other and straightened by pulling the anchor rope.
[0009] In this embodiment, the ground anchor uses a plug-in connection method, enabling the anchor head, anchor body, and anchor rod to be tightly connected together. This design allows each part to maintain a stable relative position when inserted into the ground and is also convenient for disassembly when needed. The matching of the concave head of the anchor head and the convex head of the anchor body, as well as the matching of the concave head of the anchor body and the convex head of the anchor rod, provides additional stability to the entire structure.
[0010] The use of the first hinge and the second hinge allows for a certain range of movement between the anchor head, anchor body, and anchor rod. This helps to automatically adjust the angle according to soil conditions when inserting into the ground to optimize the grip.
[0011] By pulling the anchor rope, the layout of the first limiting hole and the second limiting hole can be used to drive the anchor head, anchor body, and anchor rod to straighten. This straightening process reduces the friction between the ground anchor and the soil, making it easier for the user to remove the ground anchor from the ground.
[0012] During use, after the various parts of the ground anchor are plugged together and inserted into the ground, it is then pulled out a certain distance upward to make the anchor body and anchor head inclined in the soil. This inclined state increases the contact area between the ground anchor and the soil, thereby improving the grip and enabling the ground anchor to be firmly fixed in the ground.
[0013] When it is necessary to remove the ground anchor, the user only needs to apply a pulling force through the anchor rope to prompt the anchor rod, anchor body, and anchor head to straighten. Due to the structural design of the ground anchor, this straightening action reduces the contact area between the ground anchor and the soil, thereby reducing the resistance during extraction and making the removal process easier and faster.
[0014] In some specific embodiments, both sides of the anchor head are provided with anchor head wings to reduce the contact area with the ground and increase the pressure, facilitating insertion into the ground.
[0015] In some specific embodiments, both sides of the anchor body are provided with anchor body wings to reduce the contact area with the ground and increase the pressure, facilitating insertion into the ground.
[0016] In some specific embodiments, the number of anchor bodies is set to one or more.
[0017] In some specific embodiments, the material of the anchor rope is a high-strength wear-resistant material to increase the service life and durability.
[0018] In some specific embodiments, the materials of the anchor head, anchor body, and anchor rod are cemented carbide or steel to improve the compressive strength and wear resistance.
[0019] In some specific embodiments, the materials of the first hinge and the second hinge are stainless steel or corrosion-resistant alloy to improve the corrosion resistance and service life.
[0020] In some specific embodiments, the lengths of the anchor head, the anchor body, and the anchor rod can be set according to actual needs to adapt to soil layers at different depths.
[0021] In some specific embodiments, the surfaces of the anchor head, the anchor body, and the anchor rod can be treated against rust to improve corrosion resistance and service life.
[0022] The beneficial effects of the present utility model are as follows:
[0023] 1. Through the split design, after insertion, by pulling upward a certain distance to make the anchor body and the anchor head inclined, the contact area between the ground anchor and the soil can be increased, significantly enhancing the grip force and ensuring a firm ground fixing effect. With the design of the first limiting hole and the second limiting hole for the anchor rope, effective control of the combination of the anchor rod, the anchor body, and the anchor head is achieved. When it is necessary to take out, by pulling the anchor rope, the ground anchor nail can be easily straightened, reducing the friction with the soil, simplifying the taking-out process, and improving work efficiency.
[0024] 2. The lengths of the anchor head, the anchor body, and the anchor rod can be adjusted according to actual needs to adapt to soil layers at different depths, improving the applicability and flexibility of the ground anchor nail. This design enables the ground anchor nail to be widely applied to various geological conditions and engineering projects.
[0025] 3. The design of the anchor wings (the anchor head wings and the anchor body wings) provided on both sides of the anchor head and the anchor body effectively reduces the contact area with the ground, increases the pressure during insertion, making it easier for the ground anchor nail to penetrate the soil and improving the installation efficiency.

[0033] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0034] As Figures 1 - 3 shown, a ground anchor nail includes an anchor head 1, an anchor body 2, an anchor rod 3 and an anchor rope 4. The top end of the anchor head 1 is fixedly connected with a first hinge 13, and the top end of the first hinge 13 is fixedly connected with the bottom end of the anchor body 2. An anchor head concave head 11 is arranged at the top end of the anchor head 1, and an anchor body convex head 22 is arranged at the bottom end of the anchor body 2. The inner wall of the anchor head concave head 11 matches the outer wall of the anchor body convex head 22 for plug-in connection; the top end of the anchor body 2 is fixedly connected with a second hinge 24, and the top end of the second hinge 24 is fixedly connected with the anchor rod 3. An anchor body concave head 21 is arranged at the top end of the anchor body 2, and an anchor rod convex head 31 is arranged at the bottom end of the anchor rod 3. The outer wall of the anchor rod convex head 31 matches the inner wall of the anchor body concave head 21 for plug-in connection; a first limiting hole 41 is arranged inside the anchor rod 3, and the anchor rope 4 is slidably connected inside the first limiting hole 41. A second limiting hole 42 is arranged inside the anchor body 2, and the anchor rope 4 is slidably connected with the second limiting hole 42. One end of the anchor rope 4 is fixedly connected with the anchor head 1, and the anchor rope 4 sequentially passes through the second limiting hole 42 and the first limiting hole 41 for driving the anchor head 1, the anchor body 2 and the anchor rod 3 to be inserted into each other by pulling the anchor rope 4 for straightening.
[0035] Both sides of the anchor head 1 are set as anchor head anchor wings 12 for reducing the contact area with the ground to increase the pressure and facilitating insertion into the ground. Both sides of the anchor body 2 are set as anchor body anchor wings 23 for reducing the contact area with the ground to increase the pressure and facilitating insertion into the ground. The number of the anchor bodies 2 is set to be one or more.
[0036] During use, first, the anchor rod 3, the anchor body 2 and the anchor head 1 are sequentially inserted into each other, so that the inner wall of the anchor head concave head 11 is inserted into the outer wall of the anchor body convex head 22, and the outer wall of the anchor rod convex head 31 is inserted into the inner wall of the anchor body concave head 21, and the whole is in a vertical combined state. At this time, the ground anchor nail inserts the anchor rod 3, the anchor body 2 and the anchor head 1 into the ground manually or by mechanical force. After insertion, it can be pulled up a certain distance to make the anchor body 2 and the anchor head 1 incline in the soil, increasing the contact area between the ground anchor and the soil, thereby enhancing the grip and realizing firm ground fixation.
[0037] The removal of the ground anchor is equally convenient. One end of the anchor rope 4 is fixed to the anchor head 1 and passes through the second limiting hole 42 and the first limiting hole 41. When the ground anchor needs to be removed, by pulling the anchor rope 4, the guiding effect of the limiting holes can be utilized to straighten the combination of the anchor rod 3, the anchor body 2, and the anchor head 1, reducing the friction with the soil, and thus the ground anchor can be easily removed.
[0038] The material of the anchor rope 4 is a high-strength wear-resistant material to increase the service life and durability. The materials of the anchor head 1, the anchor body 2, and the anchor rod 3 are cemented carbide or steel to improve the compressive strength and wear resistance. The materials of the first hinge 13 and the second hinge 24 are stainless steel or corrosion-resistant alloy to improve the corrosion resistance and service life. The lengths of the anchor head 1, the anchor body 2, and the anchor rod 3 can be set according to actual needs to adapt to soil layers of different depths. The surfaces of the anchor head 1, the anchor body 2, and the anchor rod 3 can be treated with rust prevention to improve the corrosion resistance and service life.
[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
