Description

Technical Field

[0001] This utility model relates to the field of anchor bolt technology, specifically to an internally reinforced, expanded-body anti-buoyancy anchor bolt. Background Technology

[0002] With the rapid growth of my country's national economy, the scale of urban construction continues to expand. The development and utilization of underground space is becoming increasingly widespread, with functional underground structures such as underground parking garages emerging one after another. In addition, the rise of high-rise and super high-rise buildings has led to a continuous increase in foundation depth. For projects with large underground building areas, deep foundations, and relatively few building floors, the weight of the building structure itself may be insufficient to resist the buoyancy of groundwater when the groundwater level is high. In this situation, anti-buoyancy anchors have become a key technical means to resist buoyancy.

[0003] Most anchor bolts currently on the market use a single-rod structure and are directly inserted into the foundation during construction. This type of anchor bolt has significant drawbacks: the stability of a single anchor point is poor, making it prone to displacement; it cannot be expanded to increase the number of anchor points; and the strength of a single-rod structure is limited, making it difficult to meet the needs of complex projects. Further optimization and improvement are urgently needed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an internally reinforced, expanded-body anti-buoyancy anchor rod, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows: An internally reinforced, expanded-body anti-buoyancy anchor bolt includes an anchor bolt body. The anchor bolt body is provided with an expansion mechanism, which is used to expand along the anchor bolt body. A compression block is installed on the anchor bolt body by a thread, which is used to compress the expansion mechanism to expand. The anchor bolt body is fitted with a reinforcing rib by threads, and a reinforcing frame is fitted on the reinforcing rib by threads. The reinforcing frame is used to strengthen the anchor bolt body.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a support block is threadedly installed on the anchor bolt body, and the support block is used to support and limit the expansion mechanism.

[0008] The beneficial effects of adopting the above-mentioned further solutions are: During the expansion process of the expansion mechanism, the support block provides a support point to ensure that the expansion action can be carried out in the preset direction of the anchor body; at the same time, the limiting function of the support block can control the expansion range of the expansion mechanism, avoid structural damage due to excessive expansion, ensure the stability and reliability of the overall anchor structure, and thus improve the anchoring effect and anti-buoyancy performance of the anchor.

[0009] Furthermore, a sleeve is fitted onto the anchor bolt body, and a limit frame is welded to the bottom end face of the sleeve. The limit frame is slidably fitted inside the extrusion block, and a handle is installed on the sleeve. The handle is used to rotate the sleeve to drive the extrusion block to rotate through the limit frame.

[0010] The beneficial effects of adopting the above-mentioned further solutions are: By setting up a sleeve with a handle and matching limit frame and compression block, the construction worker only needs to turn the handle to drive the compression block to rotate through the limit frame, so that the compression block can move along the axial direction of the anchor body, thereby compressing the expansion mechanism, and the sleeve can be slidably removed for reuse after compression.

[0011] Furthermore, the expansion mechanism includes an installation component, an expansion component, and a reset component. The installation component is used to install the expansion component, the expansion component is used to expand and unfold, and the reset component is used to reset the expansion component.

[0012] The beneficial effects of adopting the above-mentioned further solutions are: The installation component provides a stable installation base for the expansion component, ensuring its stability during operation. The expansion component can smoothly unfold under compression, achieving large-area contact between the anchor bolt and the foundation, thus enhancing the anchoring force. The repositioning component closes the expansion component before the anchor bolt is installed, facilitating storage, reducing space occupation, and allowing the expansion component to smoothly enter the anchoring position.

[0013] Furthermore, the mounting component includes a first mounting block and a second mounting block, wherein the second mounting block is supported and limited by a support block, and the first mounting block is compressed and limited by a compression block.

[0014] The beneficial effects of adopting the above-mentioned further solutions are: The first and second mounting blocks provide reliable fixing points for the expansion assembly, ensuring its stability during installation and operation. The second mounting block works in conjunction with the support block for support, while the first mounting block works in conjunction with the extrusion block for extrusion and expansion.

[0015] Furthermore, the expansion assembly includes a second expansion plate and a first expansion plate. The first expansion plate is connected to the first mounting block via a first rotating shaft, and the second expansion plate is connected to the second mounting block via a second rotating shaft. The second expansion plate and the first expansion plate are connected by a pin.

[0016] The beneficial effects of adopting the above-mentioned further solutions are: The first and second expansion plates are connected to the mounting block via a pivot and hinged together by a pin. This connection method allows the expansion plates to expand flexibly outward around the pin as the center, forming a larger anchoring area and significantly improving the anchor's anti-buoyancy capability.

[0017] Furthermore, the reset assembly includes a first rod and a second rod. The top surface of the first rod is fixedly connected to a first mounting block, and the bottom surface of the second rod is fixedly connected to a second mounting block. The first rod is slidably sleeved inside the second rod, and the first rod is connected to the second rod via a reset spring.

[0018] The beneficial effects of adopting the above-mentioned further solutions are: The return spring provides the power to hold the expansion assembly in place, preventing it from unfolding when not in use and affecting its operation. Furthermore, the return spring is located within the first and second rods to prevent prolonged contact with the foundation after use, thus avoiding corrosion.

[0019] This utility model provides an internally reinforced, expanded-body anti-buoyancy anchor bolt. It has the following beneficial effects: The internally reinforced structure, composed of reinforcing ribs and a reinforcing frame connected by threads, forms a robust internal support system for the anchor bolt body. In practical engineering applications, this internally reinforced structure effectively disperses stress, preventing anchor bolt failures such as breakage and deformation. This ensures the anchor bolt remains stable and reliable even under high-intensity operating conditions, significantly improving its load-bearing capacity and durability.

[0020] The expansion mechanism can unfold to increase anchoring points. The first and second mounting blocks in the installation assembly cooperate with the compression block and support block, respectively, providing an installation foundation for the expansion assembly. When construction workers move the compression block using the sleeve with a handle, the first and second expansion plates unfold outwards around the pin, increasing the contact area between the anchor bolt and the foundation, significantly enhancing the anchoring force, and effectively improving the anchor bolt's anti-buoyancy performance. Simultaneously, the cooperation between the return spring in the reset assembly and the first and second rods not only ensures that the expansion assembly remains closed when not in use, facilitating storage and transportation, but also prevents the return spring from corroding due to prolonged contact with the foundation, extending the anchor bolt's service life.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6 As shown, the embodiments provided by this utility model are as follows: Example

[0025] An internally reinforced, expanded-body anti-buoyancy anchor bolt includes an anchor bolt body 1. An anchor bolt body 1 is provided with an expansion mechanism 2, which is used to expand along the anchor bolt body 1. An extrusion block 4 is installed on the anchor bolt body 1 by thread, which is used to extrude the expansion mechanism 2 to expand. A reinforcing rib 101 is threadedly installed inside the anchor bolt body 1, and a reinforcing frame 102 is threadedly installed on the reinforcing rib 101. The reinforcing frame 102 is used to reinforce the anchor bolt body 1. The combination of the reinforcing rib 101 and the reinforcing frame 102 forms a stable internal reinforcement structure, which greatly enhances the overall strength and rigidity of the anchor bolt body 1. When the anchor bolt is subjected to complex loads such as tension and compression, the reinforcing rib 101 and the reinforcing frame 102 can effectively disperse stress, prevent the anchor bolt body 1 from breaking, deforming, or failing, and significantly improve the load-bearing capacity and durability of the anchor bolt. In addition, the threaded installation method facilitates the installation and disassembly of the reinforcing rib 101 and the reinforcing frame 102, making the anchor bolt production and maintenance process more convenient and quick. Example

[0026] To increase the number of anchor points by expanding the anchor bolt within the foundation, for example, such as... Figures 1 to 6 As shown, this utility model also includes: A support block 3 is threadedly installed on the anchor body 1. The support block 3 is used to support and limit the expansion mechanism 2. During the expansion process of the expansion mechanism 2, the support block 3 provides a support point to ensure that the expansion action can be carried out in the preset direction of the anchor body 1. At the same time, the limiting function of the support block 3 can control the expansion range of the expansion mechanism 2, avoid structural damage due to excessive expansion, ensure the stability and reliability of the overall anchor structure, and thus improve the anchoring effect and anti-buoyancy performance of the anchor.

[0027] A sleeve 5 is fitted onto the anchor bolt body 1. A limit frame 501 is welded to the bottom end face of the sleeve 5. The limit frame 501 is slidably fitted inside the extrusion block 4. A handle is installed on the sleeve 5. The handle is used to rotate the sleeve 5 to drive the extrusion block 4 to rotate through the limit frame 501. By setting the sleeve 5 with a handle and the matching limit frame 501 and extrusion block 4, the construction personnel only need to rotate the handle to drive the extrusion block 4 to rotate through the limit frame 501, so that the extrusion block 4 can move along the axial direction of the anchor bolt body 1, thereby extruding the expansion mechanism 2. After extrusion, the sleeve 5 can be slidably removed for reuse.

[0028] The expansion mechanism 2 includes an installation component, an expansion component, and a reset component. The installation component is used to install the expansion component, the expansion component is used to expand and unfold, and the reset component is used to reset the expansion component. The installation component provides a stable installation foundation for the expansion component, ensuring that the expansion component remains stable during operation. The expansion component can smoothly unfold under compression, achieving a large-area contact between the anchor bolt and the foundation, thus enhancing the anchoring force. The reset component closes the expansion component before the anchor bolt is installed, facilitating storage, reducing space occupation, and allowing the expansion component to smoothly enter the anchoring position.

[0029] The mounting assembly includes a first mounting block 201 and a second mounting block 208. The second mounting block 208 is supported and limited by the support block 3, and the first mounting block 201 is limited by the compression block 4. The arrangement of the first mounting block 201 and the second mounting block 208 provides reliable fixing points for the expansion assembly, making the expansion assembly stable during installation and operation. The second mounting block 208 cooperates with the support block 3 for support, and the first mounting block 201 cooperates with the compression block 4 for compression and expansion.

[0030] The expansion assembly includes a second expansion plate 206 and a first expansion plate 204. The first expansion plate 204 is connected to the first mounting block 201 via a first pivot 202. The second expansion plate 206 is connected to the second mounting block 208 via a second pivot 207. The second expansion plate 206 and the first expansion plate 204 are connected by a pin. The first expansion plate 204 and the second expansion plate 206 are connected to the mounting block via a pivot and are hinged to each other via the pin. This connection method allows the expansion plates to flexibly expand outward around the pin when expanding, forming a larger anchoring area and significantly improving the anti-buoyancy capability of the anchor bolt.

[0031] The reset assembly includes a first rod 203 and a second rod 205. The top surface of the first rod 203 is fixedly connected to the first mounting block 201, and the bottom surface of the second rod 205 is fixedly connected to the second mounting block 208. The first rod 203 is slidably sleeved inside the second rod 205. The first rod 203 is connected to the second rod 205 through a reset spring 209. The reset spring 209 provides the power to maintain the position of the expansion assembly, preventing it from unfolding when not in use and affecting its use. Furthermore, the reset spring 209 is located inside the first rod 203 and the second rod 205 to prevent prolonged contact with the foundation after use and thus avoid corrosion.

[0032] Working principle: Initial state: The anchor bolt body 1 is internally reinforced with reinforcing ribs 101 and reinforcing frames 102 by threaded installation, forming an internally reinforced structure to enhance strength.

[0033] When the expansion mechanism 2 is in the closed state, the return spring 209 provides tension in the first rod 203 and the second rod 205, so that the first expansion plate 204 and the second expansion plate 206 are tightly attached to the anchor rod body 1, which facilitates insertion into the foundation borehole.

[0034] Insert anchor bolts: The anchor body 1, together with the closed expansion mechanism 2, is vertically inserted into the pre-drilled foundation hole.

[0035] The sleeve 5 is fitted onto the anchor bolt body 1, and the limiting frame 501 is slidably connected to the extrusion block 4. The construction worker rotates the sleeve 5 by gripping the handle.

[0036] Initiate the body expansion movement: Rotate extrusion block 4, The sleeve 5 drives the extrusion block 4 to rotate through the limit frame 501. Since the extrusion block 4 is threadedly connected to the anchor body 1, the rotation causes it to move downward along the axial direction (towards the support block 3).

[0037] Extrusion and expansion mechanism 2: The extrusion block 4 extrudes the first mounting block 201, and the support block 3 supports the second mounting block 208, forming axial pressure.

[0038] The first expansion plate 204 rotates outward around the first pivot 202, and the second expansion plate 206 rotates outward around the second pivot 207. The two are hinged together by a pin and unfold synchronously to form an "umbrella-shaped" expansion structure.

[0039] Reset component operation: The first rod 203 slides within the second rod 205 and stretches the return spring 209. The spring stores energy, but due to the enclosed structure, it avoids direct contact with the foundation.

[0040] Enlargement and anchoring: Forming anchor points: After the expansion plate is fully extended, it forms multiple points of contact with the foundation borehole wall, significantly increasing the stress-bearing area (compared to traditional anchor bolts).

[0041] Support block 3 restricts the position of the second mounting block 208 to prevent excessive expansion that could damage the structure.

[0042] Remove sleeve 5: After the expansion is completed, the sleeve 5 can be slid off along the anchor body 1 and reused.

[0043] Anti-buoyancy mechanism: Internal reinforcement: The reinforcing ribs 101 and the reinforcing frame 102 disperse the tensile force borne by the anchor bolt body 1, avoiding local stress concentration that could lead to breakage.

[0044] Pressure bearing capacity of the expanded structure: When the foundation is subjected to upward buoyancy, the friction between the expanded plate and the foundation and the reaction force of the soil are greatly increased, resisting the upward pull and achieving anti-buoyancy.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
