Description

Technical Field

[0001] This utility model relates to the field of foundation engineering technology, specifically to an anti-buoyancy anchor reinforcement structure. Background Technology

[0002] Anti-buoyancy anchors are structural components specifically designed in geotechnical engineering to resist the uplift of underground structures caused by the buoyancy of groundwater. Their core principle is to tightly bond the underground structure to a stable soil layer through an anchor body formed by the anchor rod and cement mortar. The pull-out force of the anchor rod counteracts the buoyancy effect. Traditional anti-buoyancy anchors, due to their fixed structure, cannot be adjusted in length as needed. When reinforcing deeper foundations, longer anchors must be used. Furthermore, traditional anchors have few connection points to the foundation, resulting in weak connections and a tendency to detach. The location and angle of these connection points are also not adjustable. To address these issues, a reinforced anti-buoyancy anchor structure is proposed.

[0003] As disclosed in the patent announcement CN220335967U, an anti-buoyancy anchor reinforcement structure and an anti-buoyancy anchor include an anti-buoyancy anchor body and a bracket set on the upper part of the anti-buoyancy anchor body. A lifting plate is provided on the inner side of the bracket. An anchor plate is fixedly connected to the upper part of the anti-buoyancy anchor body. The anchor plate is located on the inner side of the bracket. A spring abuts against the opposite surface of the anchor plate and the lifting plate. An adjusting screw is rotatably connected to the middle part of the upper part of the bracket. The lower part of the adjusting screw is threadedly connected to the lifting plate.

[0004] Although it achieves the goal of adding a spring to the upper part of the anti-buoyancy anchor rod body and applying pressure to the anti-buoyancy anchor rod body through spring preload to improve the pull-out resistance of the upper part of the anti-buoyancy anchor rod body, it does not solve the problem that the existing anchor rod reinforcement structure is not conducive to multi-module assembly and connection to adapt to different foundation pit depths, and is not conducive to anchoring the foundation from multiple points and different angles, thus affecting the anchoring effect. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-buoyancy anchor reinforcement structure to solve the problems mentioned in the background art, such as the inconvenience of multi-module assembly and connection to adapt to different foundation pit depths, the difficulty in anchoring the foundation from multiple points and different angles, and the impact on the anchoring effect.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide an anti-buoyancy anchor reinforcement structure, including a bearing rod and adjusting arms. The top of the bearing rod is provided with four sets of adjusting arms at equal intervals. Each adjusting arm has a hinge shaft at its end near the bearing rod, and the adjusting arm is movably connected to the bearing rod via the hinge shaft. A sliding sleeve is slidably provided on the surface of the bearing rod. Four sets of linkage arms are provided at equal intervals on the sidewall of the sliding sleeve. Each linkage arm has a lower movable shaft at its end near the sliding sleeve, and the linkage arm is movably connected to the sliding sleeve via the lower movable shaft.

[0007] Furthermore, each of the linkage arms is provided with an upper movable shaft at the end near the adjusting arm, and the linkage arm is movably connected to the adjusting arm through the upper movable shaft.

[0008] Furthermore, the side wall of the bearing rod is provided with multiple sets of pin holes at equal intervals, and the side wall of the sliding sleeve is provided with locking pins.

[0009] Furthermore, the locking pin extends through the sliding sleeve into the interior of the pin hole and is threadedly connected to the sliding sleeve, and a connecting block is provided at the end of the adjusting arm away from the bearing rod.

[0010] Furthermore, each of the connecting blocks is equipped with an anchoring screw, and the anchoring screw is threadedly connected to the connecting block.

[0011] Furthermore, an extension rod is provided below the bearing rod, and the outer surface of the extension rod is provided with a first external thread.

[0012] Furthermore, the bearing rod is provided with a first internal thread, and the first external thread is threadedly connected to the first internal thread.

[0013] Furthermore, a base block is provided below the extension rod, and a connecting rod is provided at the top of the base block.

[0014] Furthermore, the extension rod has a second internal thread inside, and the connecting rod has a second external thread on its surface, and the second external thread is threadedly connected to the second internal thread.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the anchor reinforcement structure not only realizes the multi-module assembly connection to adapt to different foundation pit depths, which facilitates anchoring the foundation from multiple points and different angles, but also improves the anchoring effect.

[0016] Before installing the anti-buoyancy anchor, a foundation pit needs to be excavated at the construction site. The pit depth should be determined according to different anti-buoyancy standards. Simultaneously, take the corresponding number of extension rods based on the pit depth and insert them into the bearing rods to connect them. Assemble multiple sets of extension rods, inserting the connecting rod into the bottommost set. Connect the base block to the bottommost set of extension rods. After connection, the length should be suitable for the corresponding pit depth. Place the base block at the bottom of the pit and pour concrete into it. The base block increases the contact area with the concrete, thereby improving the stability of the bearing rod inside the pit. After the pit is poured, wait for the concrete to dry and solidify. Then, unscrew the locking pin, move the sliding sleeve, and let it slide on the surface of the bearing rod. The sliding sleeve drives the linkage arm to rotate via the lower movable shaft. The linkage arm drives the adjusting arm to rotate around the hinge axis via the upper movable shaft. The adjusting arm drives the connecting block and anchor screw to rotate. After adjusting to the corresponding angle, reposition the locking pin. Insert the new sliding sleeve and pin hole and tighten the locking pin to maintain the adjusting arm at the current angle. Different angles of the adjusting arm result in different contact angles between the anchoring rod and the foundation. The smaller the angle between the adjusting arm and the bearing rod, the deeper the anchoring rod penetrates into the foundation, thus increasing the anchoring force on the foundation. Drill a hole in the foundation, aiming at the direction of the anchoring rod. Then, insert the expansion joint into the deep hole and drive the anchoring rod into the expansion joint. The anchoring rod drives the connecting block to move, and the connecting block pulls the adjusting arm to adjust the position of the anchoring rod. The adjustable arms are fixed in the foundation to increase the contact points between the foundation and the anchor. When buoyancy occurs, the buoyancy force can be transmitted to the foundation and dispersed through multiple adjustable arms, thus preventing the buoyancy force from pushing the foundation at the corresponding position apart. This allows for better anchoring of the foundation. The multi-module assembly connection is adapted to different foundation pit depths, facilitating anchoring of the foundation from different angles and multiple points. It increases structural strength, disperses buoyancy, and improves the anchoring effect. Attached Figure Description

[0031] Please see Figure 1-5This utility model provides an embodiment of an anti-buoyancy anchor reinforcement structure, comprising a bearing rod 4 and adjusting arms 6. The top of the bearing rod 4 is provided with four sets of adjusting arms 6 at equal intervals. Each adjusting arm 6 has a hinge shaft 12 at its end near the bearing rod 4, and the adjusting arm 6 is movably connected to the bearing rod 4 via the hinge shaft 12. A sliding sleeve 5 is slidably disposed on the surface of the bearing rod 4. Four sets of linkage arms 13 at equal intervals are disposed on the side wall of the sliding sleeve 5. Each linkage arm 13 has a lower movable shaft 14 at its end near the sliding sleeve 5, and the linkage arm 13 is connected to the sliding sleeve 5 via the lower movable shaft 14. The sleeve 5 is movably connected. The end of the linkage arm 13 near the adjusting arm 6 is provided with an upper movable shaft 11, and the linkage arm 13 is movably connected to the adjusting arm 6 through the upper movable shaft 11. The side wall of the bearing rod 4 is provided with multiple sets of pin holes 17 at equal intervals. The side wall of the sliding sleeve 5 is provided with a locking pin 15, and the locking pin 15 extends through the sliding sleeve 5 to the inside of the pin hole 17 and is threadedly connected to the sliding sleeve 5. The end of the adjusting arm 6 away from the bearing rod 4 is provided with a connecting block 16. The inside of the connecting block 16 is provided with an anchoring screw 3, and the anchoring screw 3 is threadedly connected to the connecting block 16.

[0032] An extension rod 2 is provided below the support rod 4. The outer surface of the extension rod 2 is provided with a first external thread 7, and the inside of the support rod 4 is provided with a first internal thread 10. The first external thread 7 and the first internal thread 10 are threadedly connected.

[0033] A base block 1 is provided below the extension rod 2, and a connecting rod 9 is provided at the top of the base block 1. The extension rod 2 has a second internal thread 18 inside, and the surface of the connecting rod 9 has a second external thread 8, and the second external thread 8 is threadedly connected to the second internal thread 18.

[0034] Before installing the anti-buoyancy anchor, a foundation pit needs to be excavated at the construction site. The pit depth should be determined according to different anti-buoyancy standards. Simultaneously, take the corresponding number of extension rods 2 based on the pit depth and insert them into the bearing rod 4. Connect the extension rods 2 to the bearing rod 4 using the first external thread 7 and the first internal thread 10. Then, assemble multiple sets of extension rods 2 using the first external thread 7 and the second internal thread 18. Insert the connecting rod 9 into the bottommost set of extension rods 2, and connect the base block 1 using the second external thread 8 and the second internal thread 18. Connecting to the lowest extension rod 2, the length is adapted to the corresponding pit depth. The base block 1 is placed at the bottom of the pit, and concrete is poured into the pit. The base block 1 increases the contact area with the concrete, thereby improving the stability of the bearing rod 4 inside the pit. After the pit is poured, wait for the concrete to dry and solidify. Then, unscrew the locking pin 15 and move the sliding sleeve 5. The sliding sleeve 5 slides on the surface of the bearing rod 4. The sliding sleeve 5 drives the linkage arm 13 to rotate via the lower movable shaft 14. The linkage arm 13 drives the adjusting arm 6 to rotate around the hinge shaft 12 via the upper movable shaft 11. The adjusting arm 6 then drives... The connecting block 16 and the anchoring screw 3 rotate. After adjusting to the corresponding angle, the locking pin 15 is reinserted into the sliding sleeve 5 and the pin hole 17 and tightened to keep the adjusting arm 6 at the current angle. Different angles of the adjusting arm 6 allow the anchoring screw 3 to contact the foundation at different angles. The smaller the angle between the adjusting arm 6 and the bearing rod 4, the deeper the anchoring screw 3 penetrates into the foundation, thus increasing the anchoring tension on the foundation. A hole is drilled in the foundation, aiming at the direction of the anchoring screw 3. Then, the expansion joint is placed into the deep hole, and the anchoring screw 3 is driven into the expansion joint. With the threaded connection between the anchoring screw 3 and the connecting block 16, The anchoring screw 3 drives the connecting block 16 to move, and the connecting block 16 pulls the adjusting arm 6 to fix multiple sets of adjusting arms 6 in the foundation, thereby increasing the contact points between the foundation and the anchor. When floating occurs, the floating force can be transmitted to the foundation through multiple sets of adjusting arms 6 and dispersed, thereby preventing the buoyancy force from pushing the foundation at the corresponding position, thus better anchoring the foundation. This realizes multi-module assembly and connection to adapt to different foundation pit depths, facilitates anchoring the foundation from different angles, facilitates anchoring the foundation from multiple points, increases structural strength, disperses floating buoyancy, and improves the anchoring effect.

[0035] Working principle: Before installing the anti-buoyancy anchor, a foundation pit needs to be excavated at the construction site. The depth of the pit should be determined according to different anti-buoyancy standards. Simultaneously, a corresponding number of extension rods 2 are taken based on the pit depth. The extension rods 2 are inserted into the bearing rods 4. The extension rods 2 are connected to the bearing rods 4 by the threaded connection between the first external thread 7 and the first internal thread 10. Multiple sets of extension rods 2 are assembled by the threaded connection between the first external thread 7 and the second internal thread 18. The connecting rod 9 is inserted into the bottommost set of extension rods 2. With the threaded connection between thread 8 and the second internal thread 18, connect the base block 1 to the lowest extension rod 2. After connection, the length can be adapted to the corresponding pit depth. Place the base block 1 at the bottom of the pit and pour concrete into the pit. The base block 1 increases the contact area with the concrete, thereby improving the stability of the bearing rod 4 inside the pit. After the pit is poured, wait for the concrete to dry and solidify. Then unscrew the locking pin 15 and move the sliding sleeve 5. The sliding sleeve 5 slides on the surface of the bearing rod 4, and the sliding sleeve 5 drives the linkage arm 13 through the lower movable shaft 14. The linkage arm 13 drives the adjusting arm 6 to rotate around the hinge shaft 12 via the upper movable shaft 11. The adjusting arm 6 then drives the connecting block 16 and the anchoring screw 3 to rotate. After adjusting to the corresponding angle, the locking pin 15 is reinserted into the sliding sleeve 5 and the pin hole 17 and tightened to keep the adjusting arm 6 at the current angle. Different angles of the adjusting arm 6 allow for different contact angles between the anchoring screw 3 and the foundation. The smaller the angle between the adjusting arm 6 and the bearing rod 4, the deeper the anchoring screw 3 penetrates into the foundation, thus increasing the anchoring tension on the foundation. Drill a hole in the foundation in the direction of the anchoring screw 3, then insert the expansion joint into the deep hole, and drive the anchoring screw 3 into the expansion joint. With the anchoring screw 3 and the connecting block 16 connected by threads, the anchoring screw 3 drives the connecting block 16 to move, and the connecting block 16 pulls the adjusting arm 6 to fix multiple sets of adjusting arms 6 in the foundation, thereby increasing the contact points between the foundation and the anchor. When floating occurs, the floating force can be transmitted to the foundation through multiple sets of adjusting arms 6 and dispersed, thereby preventing the buoyancy force from pushing the foundation at the corresponding position open, thus better anchoring the foundation.
