Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to an anti-loosening and anti-buoyancy anchor rod. Background Technology

[0002] Anti-buoyancy anchors, an indispensable part of modern construction engineering, play a crucial role, especially in underground structure design, aiming to effectively address the potential threat of groundwater buoyancy to building foundations. This unique engineering measure, through an anchor structure that penetrates deep into the soil layer, connects part of the building's weight to the deep, stable soil layer of the foundation, thereby balancing the buoyancy generated by rising groundwater and ensuring the overall stability and safety of the building structure. Compared to traditional foundation piles, anti-buoyancy anchors exhibit significant differences in design concept, construction methods, and stress characteristics. Foundation piles, as the main components supporting the weight of a building, have the core function of resisting load pressure from above. Their design typically focuses on the compressive strength of the pile shaft and the bearing capacity of the soil layer at the pile tip, ensuring that the load can be effectively transferred to the depths of the foundation. As the building load increases or decreases, the pressure borne by the foundation pile also changes accordingly; this dynamic balance is key to ensuring the stability of the building. Anti-buoyancy anchors, on the other hand, are pull-out piles specifically designed to resist groundwater buoyancy. Their working principle is completely opposite to that of foundation piles; instead of bearing downward pressure, they resist upward tension. When the groundwater level rises, anchor bolts, through their strong pull-out resistance, transfer part of the building's weight to deeper, stable soil layers, thus counteracting buoyancy and preventing the building from floating. As the groundwater level fluctuates, the tension on the anchor bolts also changes; this dynamic adjustment mechanism, adapting to the environment, is the ingenious design feature of anti-buoyancy anchor bolts. Furthermore, the construction process of anti-buoyancy anchor bolts is more complex and precise. It requires accurate geological exploration to determine the anchor bolt's embedment depth, spacing, and angle, ensuring that the anchor bolts can penetrate weak soil layers and anchor into stable soil layers with higher bearing capacity. Simultaneously, the selection of anchor bolt materials, diameter, and anchorage length must be precisely calculated and designed according to specific engineering conditions to achieve the best anti-buoyancy effect. With its unique force mechanism and complex construction process, anti-buoyancy anchor bolts have become an indispensable anti-buoyancy measure in modern construction engineering. As guardians of underground engineering, the importance of anti-buoyancy anchor bolts is self-evident. They not only incorporate advanced engineering technology concepts in their design and construction but also fully consider the dynamic changes in environmental factors, such as the seasonal fluctuations in groundwater levels. Through scientific design and meticulous construction, anti-buoyancy anchors can flexibly cope with various challenges, ensuring the stability and safety of buildings and providing solid support for urban construction and development. They not only effectively address the challenges of groundwater buoyancy, guaranteeing the long-term stability and safety of buildings, but also demonstrate the wisdom and creativity of engineering technicians in dealing with complex geological environments.

[0003] According to Chinese Patent No. CN221589576U, an anti-buoyancy anchor bolt is disclosed, comprising several anchor bars, an installation component, a snap-fit ​​component, and a surrounding component. Each anchor bar is disposed within the installation component, and the snap-fit ​​components correspond one-to-one with the anchor bars. The surrounding component is disposed on the installation component. This utility model, through the installation component, snap-fit ​​component, and surrounding component, can mechanically connect the anchor bars without welding, avoiding the problem of weak welding that may occur during welding. It can also accurately position the anchor bars, avoiding the problem of bar misalignment that may occur during welding.

[0004] However, during use, existing anti-buoyancy anchors are prone to loosening due to gaps between the anchor and the hole. Furthermore, traditional anti-buoyancy anchors do not have the function of preventing loosening, causing inconvenience to users. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the problem that, during the use of existing anti-buoyancy anchor rods, the inserted anchor rod is easy to loosen due to the gap between the anchor rod and the hole, and traditional anti-buoyancy anchor rods do not have the function of preventing loosening, which causes inconvenience to users.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] An anti-loosening and anti-buoyancy anchor bolt includes an installation cylinder, a fixed bottom cone, a cylindrical guide rail, a sliding cone, a fixing hole, a limiting pin, a docking plate, and an anchor bolt body. The installation cylinder has a fixed bottom cone inside, and a cylindrical guide rail is welded to the upper side of the fixed bottom cone. A sliding cone is welded to the cylindrical guide rail. The installation cylinder has a fixing hole on its side, and a limiting pin is installed in the fixing hole. The installation cylinder has a docking plate on its upper side, and a fixing groove is provided on the docking plate. The anchor bolt body is installed in the fixing groove.

[0008] As a preferred technical solution of this utility model, the mounting cylinder and the fixed bottom cone are concentrically fitted, a limiting rod is provided on the lower side of the mounting cylinder, and a first limiting plate is provided on the cylindrical guide rail. The first limiting plate is located on the upper side of the limiting rod, which can effectively prevent the cylindrical guide rail from sliding out of the mounting cylinder.

[0009] As a preferred embodiment of this utility model, a spring buffer rod is provided on the lower side of the mounting cylinder, and a fixing plate is provided at the bottom of the spring buffer rod, which is fixed on the cylindrical guide rail.

[0010] As a preferred embodiment of this utility model, the limiting pin is provided with a second limiting disc, the radius of which is larger than that of the fixing hole.

[0011] As a preferred embodiment of this utility model, the docking plate is provided with three fixing grooves, the anchor rod body is provided with an extension plate, and the docking hole opened on the extension plate is provided with the anchor rod body.

[0012] As a preferred technical solution of this utility model, an extension rod is provided in the docking hole. The extension rod is located on the upper side of the anchor body. The extension plate is provided with fastening bolts on the side of the extension rod and the anchor body, so that the user can extend the anchor body according to the construction conditions.

[0013] The beneficial effects of this utility model are as follows:

[0014] Because this invention has an anti-loosening function, the device is equipped with a limiting pin. When the user applies a downward force to the fixed bottom cone, the cylindrical guide rail and the sliding cone on the upper side of the fixed bottom cone will move upward, thereby moving the limiting pin that is in contact with the sliding cone to contact the cylindrical guide rail, forcing the limiting pin to extend and fix the device to prevent loosening.

[0025] Example 1

[0026] exist Figure 1-4 This utility model provides a technical solution: an anti-loosening and anti-buoyancy anchor rod, comprising an installation cylinder 1, a fixed bottom cone 2, a cylindrical guide rail 3, a sliding cone 4, a fixing hole 5, a limiting nail 6, a docking plate 7, and an anchor rod body 8. The installation cylinder 1 has a fixed bottom cone 2 inside, and a cylindrical guide rail 3 is welded to the upper side of the fixed bottom cone 2. The sliding cone 4 is welded to the cylindrical guide rail 3. The installation cylinder 1 has a fixing hole 5 on its side, and a limiting nail 6 is provided in the fixing hole 5. The installation cylinder 1 has a docking plate 7 on its upper side, and a fixing groove 9 is provided on the docking plate 7. The anchor rod body 8 is provided in the fixing groove 9.

[0027] In one aspect of this embodiment, the mounting cylinder 1 and the fixed bottom cone 2 are concentrically fitted. A limiting rod 10 is provided on the lower side of the mounting cylinder 1, and a first limiting plate 11 is provided on the cylindrical guide rail 3. The first limiting plate 11 is located above the limiting rod 10. A spring buffer rod 12 is provided on the lower side of the mounting cylinder 1, and a fixing plate 13 is provided at the bottom of the spring buffer rod 12. The fixing plate 13 is fixed on the cylindrical guide rail 3. The spring buffer rod 12 can prevent the fixed bottom cone 2 from displacing into the mounting cylinder 1.

[0028] In one aspect of this embodiment, the limiting pin 6 is provided with a second limiting disc 14, the radius of which is larger than that of the fixing hole 5, which can effectively prevent the limiting pin 6 from running out of the fixing hole 5.

[0029] In one aspect of this embodiment, the docking plate 7 is provided with three fixing grooves 9, the anchor rod body 8 is provided with an extension plate 15, the docking hole 16 opened on the extension plate 15 is provided with the anchor rod body 8, the docking hole 16 is provided with an extension rod 17, the extension rod 17 is located on the upper side of the anchor rod body 8, and the extension plate 15 is provided with fastening bolts 18 on the side of the extension rod 17 and the anchor rod body 8, which facilitates the user's construction.

[0030] The working principle of this utility model is as follows: During use, the user first selects a suitable extension rod 17 according to the construction conditions and installs it in the docking hole 16 of the extension plate 15. The extension rod 17 is then fixed to the anchor body 8 by fastening bolts 18. The user then places the installation cylinder 1 into the pre-opened hole. When the fixed bottom cone 2 touches the bottom, the user continues to apply a downward force to the fixed bottom cone 2, causing it to move upward. This pushes the sliding cone 4 on the cylindrical guide rail 3 to move upward. Under the action of the sliding cone 4, the limiting pin 6 moves outward from the fixed hole 5. When the cylindrical guide rail 3 contacts the limiting pin 6, the limiting pin 6 stops moving. At this time, the user needs to apply a constant pressure on the upper side of the equipment and then pour in the mud. After the mud solidifies, the pressure can be released.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
