AI Technical Summary
When anchoring existing bolts is installed upwards, the anchoring agent tends to flow downwards due to gravity, resulting in insufficient filling and reduced anchoring effect. Furthermore, existing devices are prone to leakage during the squeezing and mixing process.
An anchoring device comprising a fixing component, a pushing component, and a lifting component is designed. Anchoring agent is fed in through a piston rod, a tension spring, and a lifting component. A silicone plug is used to temporarily seal the anchoring hole. A clamping plate abuts against the inner wall of the anchoring hole to ensure that the anchoring agent is fully filled and fixed.
This avoids the anchoring agent from being broken or prematurely released during delivery, ensuring that the anchoring agent fully fills the anchoring hole, improving the anchoring effect, and eliminating the need for support when working at heights, thus facilitating construction.

Abstract
Description
Technical Field
[0001] This invention belongs to the field of civil engineering construction technology, specifically an anchoring device for civil engineering construction. Background Technology
[0002] Anchor bolt installation is commonly used in civil engineering construction. Current anchor bolt installation methods involve first drilling anchor holes at the anchoring location, then removing impurities and dust from the holes using cleaning equipment, inserting anchoring agent into the holes, and finally using equipment to screw the anchor bolt into the hole. Simultaneously, the anchor bolt squeezes and mixes the anchoring agent, filling the hole and allowing it to adhere and harden. This method is typically suitable for wall anchoring but not for upward or top-mounted anchoring. During construction, the anchoring agent may fall out of the hole due to gravity, requiring the anchor bolt to push it back in. Furthermore, during the squeezing and mixing process, the anchoring agent tends to flow downwards under gravity, resulting in insufficient filling of the top of the hole. This reduces the bonding area between the anchoring agent and the hole, leading to leakage and ultimately reducing the anchor bolt's effectiveness.
[0003] Therefore, an anchoring device for civil construction is proposed to solve the above problems. Summary of the Invention
[0004] To address the problems mentioned in the background art, the present invention provides an anchoring device for civil construction.

A spring is fitted outside the pull rod, with one end connected to the locking block and the other end connected to the fixed cylinder. An air hole is opened above the outer side of the fixed cylinder, and breathable cotton is fixedly fitted into the air hole.
[0006] Preferably, four movable blocks are slidably installed inside the fixed ring, and a clamping plate located above the fixed ring is connected to the inner side of each movable block. An inclined block located inside the fixed ring is connected to the bottom of each movable block, and a spring is connected to the inner side of the inclined block. The other end of the spring is connected to the inner wall of the fixed ring.
[0007] Preferably, a rotating ring is threaded onto the outside of the fixed ring, and a compression ring extending into the fixed ring is installed inside the rotating ring, with the inclined surface on the inner side of the compression ring abutting against the inclined block.
[0008] Preferably, the lifting assembly includes a push block movably fitted inside the mounting cylinder. The push block is connected to a piston rod. A push rod is movably fitted inside the push block. A silicone plug is placed above the push rod. A conical block located inside the push block is fixedly fitted to the outside of the push rod. A movable block located inside the push block is connected to the bottom end of the push rod. A spring is connected to the bottom of the movable block. The other end of the spring is connected to the inner wall of the push block. The bottom diameter of the movable block is smaller than the top diameter.
[0009] Preferably, the push block is abutted by four circumferentially arranged clamping plates 2. The clamping plates 2 are connected to cotton pads. The inner side of the clamping plates 2 is connected to two limiting rods. The other end of the limiting rods extends into the push block and is connected to a fixing plate. The limiting rods are fitted with springs 4. The two ends of the springs 4 are respectively connected to the fixing plate and the inner wall of the push block.
[0010] Preferably, a square rod is movably sleeved inside the fixed plate, one end of the square rod is connected to a second inclined block, and a second tension spring is sleeved outside the square rod. The two ends of the second tension spring are respectively connected to the fixed plate and the second inclined block, and the inclined surface of the second inclined block abuts against the outside of the cone block.
[0011] Preferably, air chamber 1 is provided on both sides of the inside of the push block, and air chamber 2 is provided on both sides of the inside of the push block below air chamber 1. Air chamber 1 and air chamber 2 are connected by an air cavity. Piston rod 2 is sleeved inside air chamber 1. One end of piston rod 2 can abut against the inner side of clamping plate 2. Piston block is sleeved inside air chamber 2. Tension spring 3 is connected to the top of piston block. The other end of tension spring 3 is connected to the inner wall of air chamber 2. Spring 5 is connected to the bottom of piston block. Push rod 2 is connected to the other end of spring 5. Locking block 2 is connected to the other end of push rod 2. The bottom of locking block 2 extends to the lower part of the inside of the push block.
[0012] Preferably, a locking block three is movably sleeved below the bottom of both sides of the push block, which can be locked inside the moving block. The locking block three is located inside the locking block two, and a spring six is connected to the outside of the locking block three. The other end of the spring six is connected to the inner wall of the push block.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, by setting up a piston rod, a tension spring, and a lifting assembly, pulls the pull rod 2 outward, causing the pull rod 2 to disengage the locking block 1 from the piston rod 1. At this time, the spring 2 is compressed, and the elastic recovery of the tension spring 1 pulls the piston rod 1, causing the lifting assembly to rise. During the rising process of the piston rod 1, the gas inside the fixed cylinder is slowly discharged through the vent on the fixed cylinder. Since the vent diameter is small, it can buffer the elastic recovery of the tension spring 1. Finally, the anchoring agent is delivered to the deepest part of the anchoring hole. This design can prevent the anchoring agent from impacting and breaking against the inner wall of the anchoring hole due to the piston rod 1 rising too quickly, and prevent the anchoring agent from being released prematurely. At the same time, it can support the anchoring agent in the anchoring hole, preventing the anchoring agent from accidentally falling out after being inserted.
[0014] This invention utilizes a push rod and a silicone plug. Under the restoring force of a spring, the moving block and push rod rise, pushing the compressed silicone plug from the inside of the clamping plate. Once the silicone plug is completely detached from the clamping plate, it expands and blocks the anchoring hole, temporarily sealing the anchoring agent inside. This design prevents the anchoring agent from accidentally falling out after complete detachment. Even if the anchor rod punctures the middle part of the silicone plug during subsequent compression and stirring of the anchoring agent, its outer side remains supported in the anchoring hole, preventing further flow of the anchoring agent and ensuring it fully fills the top of the anchoring hole. After full filling, the silicone plug is squeezed out of the anchoring hole by the anchoring agent. Since the silicone plug does not react with the anchoring agent, it does not affect the adhesiveness of the anchoring agent, further improving the anchoring effect.
[0015] This invention uses a clamping plate and a compression ring to insert anchoring agent into a fixed ring, allowing its bottom to fall into an installation cylinder and onto a silicone plug. The fixed cylinder is then raised, inserting the anchoring agent and clamping plate into the anchoring hole. Rotating the rotating ring causes it to descend along the outside of the fixed ring. At this point, the contact position between the compression ring and the inclined block changes. The spring, under compression, pushes the inclined block, movable block, and clamping plate outwards due to its restoring elasticity, causing clamping plate to contact the inner wall of the anchoring hole and increasing friction. Finally, the fixing assembly and the pushing assembly are fixed below the anchoring hole. This design secures the entire device to the anchoring hole, eliminating the need for workers to lift it while operating at heights, thus facilitating their work. The clamping plate also provides positioning, preventing the fixed ring from tilting when it aligns with the anchoring hole. Attached Figure Description

[0018] 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.
[0019] like Figures 1 to 8 As shown, the present invention provides an anchoring device for civil construction, including a fixing component 1, an upward pushing component 2 and a lifting component 3; The push-up component 2 is connected below the fixed component 1, and the lifting component 3 is fitted inside the fixed component 1; The fixing component 1 includes a mounting cylinder 11, and a fixing ring 12 is fixedly connected to the top of the mounting cylinder 11; the lifting component 3 is sleeved inside the mounting cylinder 11. The upward pushing assembly 2 includes a fixed cylinder 21, which is installed below the mounting cylinder 11. A piston rod 22 is sleeved inside the fixed cylinder 21, with its top end extending into the mounting cylinder 11 and connected to the lifting assembly 3. A tension spring 23 is sleeved outside the piston rod 22, with one end connected to the piston rod 22 and the other end connected to the fixed cylinder 21. A pull rod 24 extending below the fixed cylinder 21 is connected to the bottom end of the piston rod 22. Both sides of the fixed cylinder 21 are equipped with locking blocks 25 that are engaged inside the piston rod 22. The outer side of the locking blocks 25 is connected to the pull rod 26. The other end of the pull rod 26 extends to the outside of the fixed cylinder 21. The outside of the pull rod 26 is fitted with a spring 27. One end of the spring 27 is connected to the locking blocks 25, and the other end of the spring 27 is connected to the fixed cylinder 21. An air hole is opened on the upper side of the fixed cylinder 21, and a breathable cotton 28 is fixedly fitted in the air hole on the fixed cylinder 21.
[0020] Using the above scheme: Pulling the pull rod 26 outward can cause the pull rod 26 to disengage the locking block 25 from the piston rod 22. At this time, the spring 27 is compressed, and the elastic recovery of the tension spring 23 will pull the piston rod 22 to lift the lifting assembly 3. During the process of the piston rod 22 rising, the gas inside the fixed cylinder 21 is slowly discharged through the air hole on the fixed cylinder 21. Since the diameter of the air hole is small, it can buffer the elastic recovery of the tension spring 23. Finally, the anchoring agent is sent into the deepest part of the anchoring hole, thus avoiding the anchoring agent from colliding and breaking with the inner wall of the anchoring hole due to the piston rod 22 rising too fast, and preventing the anchoring agent from being released prematurely.
[0021] like Figures 1 to 3 As shown, four movable blocks 15 are slidably mounted inside the fixed ring 12 and arranged in a circle. The inner side of the movable block 15 is connected to a clamping plate 18 located above the fixed ring 12. The bottom of the movable block 15 is connected to an inclined block 16 located inside the fixed ring 12. The inner side of the inclined block 16 is connected to a spring 17. The other end of the spring 17 is connected to the inner wall of the fixed ring 12.
[0022] Using the above scheme: Due to the restoring effect of the elastic force of spring-17, the inclined block-16, movable block-15 and clamp-18 will be pushed to move outward, so that clamp-18 abuts against the inner wall of the anchor hole, and the friction between clamp-18 and anchor hole is increased. Finally, the fixing component 1 and the pushing component 2 are fixed as a whole below the anchor hole.
[0023] like Figures 1 to 3 As shown, a rotating ring 13 is threaded onto the outside of the fixed ring 12, and a compression ring 14 extending into the fixed ring 12 is installed inside the rotating ring 13. The inclined surface on the inner side of the compression ring 14 abuts against the inclined block 16.
[0024] Using the above scheme: Rotate the rotating ring 13 so that the rotating ring 13 descends along the outside of the fixed ring 12. At this time, the contact position between the compression ring 14 and the inclined block 16 changes, and the elastic force of the spring 17 is released. The rotating ring 13 and the compression ring 14 can control the release and contraction of the elastic force of the spring 17.
[0025] like Figure 4 , Figures 6 to 8 As shown, the lifting assembly 3 includes a push block 31, which is movably fitted inside the mounting cylinder 11. The push block 31 is connected to the piston rod 22. A push rod 32 is movably fitted inside the push block 31. A silicone plug 325 is placed above the push rod 32. A cone block 33 located inside the push block 31 is fixedly fitted outside the push rod 32. A movable block 34 located inside the push block 31 is connected to the bottom end of the push rod 32. A spring 35 is connected to the bottom of the movable block 34. The other end of the spring 35 is connected to the inner wall of the push block 31. The bottom diameter of the movable block 34 is smaller than the top diameter.
[0026] The above scheme is adopted: under the elastic recovery action of spring 35, the moving block 34 and push rod 1 32 are pushed up, and the compressed silicone plug 325 on push rod 1 32 is pushed out from the inside of clamp 2 36. When the silicone plug 325 is completely separated from clamp 2 36, under the recovery action of silicone plug 325 itself, it expands and blocks in the anchoring hole, and temporarily seals the anchoring agent above in the anchoring hole.
[0027] like Figure 4 , Figures 6 to 8 As shown, the push block 31 is abutted by four surrounding clamping plates 36. The clamping plates 36 are connected to cotton pads 37. The inner side of the clamping plates 36 is connected to two limiting rods 38. The other end of the limiting rods 38 extends into the push block 31 and is connected to a fixing plate 310. The limiting rods 38 are fitted with springs 39. The two ends of the springs 39 are connected to the fixing plate 310 and the inner wall of the push block 31, respectively.
[0028] The above scheme is adopted: due to the descent of push rod 32 and cone block 33, under the elastic recovery action of spring 4 39, clamping plate 2 36, limiting rod 38 and fixing plate 310 are driven to retract inward, and the silicone plug 325 on push rod 32 is compressed inside by clamping plate 2 36.
[0029] like Figure 4 , Figures 6 to 8 As shown, a square rod 311 is movably sleeved inside the fixed plate 310. One end of the square rod 311 is connected to a second inclined block 312. A second tension spring 313 is sleeved outside the square rod 311. The two ends of the second tension spring 313 are connected to the fixed plate 310 and the second inclined block 312 respectively. The inclined surface of the second inclined block 312 abuts against the outside of the cone block 33.
[0030] Using the above scheme: When push rod 32 moves upward, cone block 33 will squeeze and push inclined block 312 and square rod 311 to move outward. At this time, tension spring 313 is stretched. Since the cotton pad 37 outside clamping plate 36 is blocked by the inner wall of the anchoring hole, fixing plate 310 and limiting rod 38 cannot move outward. When the lifting assembly 3 is pulled out from the anchoring hole, the elastic force of tension spring 313 is released, pulling fixing plate 310, limiting rod 38, clamping plate 36 and cotton pad 37 to move outward.
[0031] like Figure 4 , Figures 6 to 8 As shown, air chamber 1 314 is provided on both sides of the push block 31, and air chamber 2 317 is provided on both sides of the push block 31, located below air chamber 1 314. Air chamber 1 314 and air chamber 2 317 are connected by air cavity 316. Piston rod 2 315 is installed inside air chamber 1 314. One end of piston rod 2 315 can abut against the inner side of clamping plate 2 36. Piston block 318 is installed inside air chamber 2 317. Tension spring 3 319 is connected to the top of piston block 318. The other end of tension spring 3 319 is connected to the inner wall of air chamber 2 317. Spring 5 320 is connected to the bottom of piston block 318. Push rod 2 321 is connected to the other end of push rod 2 321. Locking block 2 322 is connected to the other end of push rod 2 321. The bottom of locking block 2 322 extends to the lower part of the push block 31.
[0032] Using the above scheme: when the clamping plate 2 36 releases its contact with the piston rod 2 315, the tension spring 3 319, under the restoring effect of its elasticity, will drive the piston block 318, spring 5 320 and locking block 2 322 to retract upward and disengage from locking block 3 323. Due to the rise of the piston block 318, the gas inside the air chamber 2 317 can be pushed into the air chamber 1 314 through the air cavity 316, and push the piston rod 2 315 to move outward.
[0033] like Figure 4 , Figures 6 to 8 As shown, a locking block 323 is movably fitted below the bottom of both sides of the push block 31, which can be locked inside the moving block 34. The locking block 323 is located inside the locking block 2 322. A spring 6 324 is connected to the outside of the locking block 323. The other end of the spring 6 324 is connected to the inner wall of the push block 31.
[0034] Using the above scheme: When the silicone plug 325 pushes the push rod 32, cone block 33 and moving block 34 downward, the compressed spring 35 is further compressed. At the same time, the moving block 34 presses the arc surface of the locking block 323, causing the locking block 323 to be pressed into the inside of both sides of the push block 31. At the same time, the spring 6 324 is compressed. The movement of the locking block 323 will compress and shrink the locking block 2 322. When the locking groove in the locking block 323 moves to the locking block 2 322, under the elastic force of the spring 5 320, the locking block 2 322 is pushed into the inside of the locking block 323, fixing the locking block 323, thereby also releasing the fixing of the moving block 34 and the locking block 323.
[0035] Working principle and usage process of this invention: The anchoring agent is inserted into the fixing ring 12, allowing its bottom to fall into the mounting cylinder 11 and onto the silicone plug 325. The fixing cylinder 21 is then raised, and the anchoring agent and clamp plate 18 are inserted into the anchoring hole. The rotating ring 13 is then rotated, causing it to descend along the outside of the fixing ring 12. At this point, the contact position between the compression ring 14 and the inclined block 16 changes. Due to the restoring effect of the elastic force, the spring 17 in the compression state pushes the inclined block 16, the movable block 15, and the clamp plate 18 to move outward, causing the clamp plate 18 to contact the inner wall of the anchoring hole and increasing the friction between the clamp plate 18 and the anchoring hole. Finally, the fixing assembly 1 and the pushing assembly 2 are fixed together below the anchoring hole, thus fixing the entire device to the anchoring hole and avoiding the need for workers to lift it when working at height.
[0036] Pulling the pull rod 26 outwards causes the pull rod 26 to disengage the locking block 25 from the piston rod 22. At this time, the spring 27 is compressed, and the elastic recovery of the tension spring 23 pulls the piston rod 22, causing the lifting assembly 3 to rise. During the rise of the piston rod 22, the gas inside the fixed cylinder 21 is slowly discharged through the vent on the fixed cylinder 21. Since the vent diameter is small, it can buffer the elastic recovery of the tension spring 23. Finally, the anchoring agent is delivered to the deepest part of the anchoring hole, thus avoiding the anchoring agent from colliding and breaking with the inner wall of the anchoring hole due to the piston rod 22 rising too quickly, and preventing the anchoring agent from being released prematurely.
[0037] When the anchoring agent is pushed into the anchoring hole and blocked at the top, the release of the elastic force of the tension spring 23 will cause the anchoring agent to push the push rod 32, cone block 33, and moving block 34 downward through the silicone plug 325. This will further compress the compressed spring 35, while the moving block 34 will press the arc surface of the locking block 323, causing the locking block 323 to be pressed inward on both sides of the push block 31. At the same time, the spring 6 324 will be compressed, and the movement of the locking block 323 will compress and retract the locking block 2 322. When the locking groove in the locking block 323 moves to the locking block 2 322, the elastic force of the spring 5 320 will push the locking block 2 322 into the interior of the locking block 323, fixing the locking block 323 in place. At this time, the release of the tension spring 323 will also be achieved. The moving block 34 and the locking block 323 are fixed. The construction personnel rotate the rotating ring 13 to rise, release the fixing of the clamping plate 18 to the anchoring hole, and then pull the clamping plate 18 and the lifting assembly 3 out of the anchoring hole. When pulling out, the elastic force of the tension spring 23 will be released first. As the pulling continues, the push block 31, the clamping plate 2 36 and the cotton pad 37 will move out of the hole. Under the elastic force recovery of the spring 3 35, the moving block 34 and the push rod 1 32 will be pushed up, and the compressed silicone plug 325 on the push rod 1 32 will be pushed out from the inside of the clamping plate 2 36. When the silicone plug 325 is completely separated from the clamping plate 2 36, under the recovery of the silicone plug 325 itself, it expands and blocks in the anchoring hole, and temporarily seals the anchoring agent above in the anchoring hole.
[0038] During the subsequent compression and mixing of the anchoring agent by the anchor rod, the anchor rod will puncture the middle part of the silicone plug 325. Its outer side can still support in the anchoring hole, which can block the downward flow of the anchoring agent and ensure that the anchoring agent fully fills the top of the anchoring hole. After it is fully filled, the silicone plug 325 will be squeezed out of the anchoring hole by the compression of the anchoring agent. Since the silicone plug 325 does not react with the anchoring agent, it will not affect the adhesiveness of the anchoring agent.
[0039] When push rod 32 moves upward, cone block 33 will squeeze and push inclined block 312 and square rod 311 to move outward. At this time, tension spring 313 is stretched. Since the cotton pad 37 outside clamping plate 36 is blocked by the inner wall of the anchoring hole, fixing plate 310 and limiting rod 38 cannot move outward. When the lifting assembly 3 is pulled out from the anchoring hole, the elastic force of tension spring 313 is released, which will pull fixing plate 310, limiting rod 38, clamping plate 36 and cotton pad 37 to move outward. At the same time, limiting rod 38 is compressed, and clamping plate 36 releases its contact with piston rod 315. At this time, tension spring 319 in the stretched state will drive piston block 318, spring 320 and locking block 322 to retract upward and disengage from locking block 323 under the restoring effect of elastic force. Due to the rise of piston block 318, the gas inside air chamber 317 can be pushed into the air chamber 316. In chamber 314, the piston rod 315 is pushed outward. As the locking block 322 disengages from the locking block 323, the spring 324 restores the elasticity, allowing the locking block 323 to reset. The worker places a new silicone plug 325 on the push rod 32 and presses the push rod 32 inward to retract it into the push block 31, and then re-engages the moving block 34 and the locking block 323. Because the bottom diameter of the moving block 34 is small, when the moving block 34 squeezes the locking block 323, it will not push the locking block 323 to the locking block 322. The descent of the moving block 34 compresses the spring 35. As the push rod 32 and the cone block 33 descend, the spring 49 restores the elasticity, causing the clamping plate 36, the limiting rod 38, and the fixing plate 310 to retract inward. The clamping plate 36 compresses the silicone plug 325 on the push rod 32 inside for future use.
