Description

Technical Field

[0001] This invention relates to the field of anchor bolt technology, specifically to a high-strength mechanical anchor bolt for anti-buoyancy basement slabs. Background Technology

[0002] As the core underground space of a building project, the basement's anti-buoyancy base plate needs to withstand the buoyancy of groundwater for a long time. If the anchoring structure fails, it can easily lead to the base plate floating, cracking, or even overall displacement, seriously threatening the safety of the building structure.

[0003] According to announcement number CN205399503U, a high-strength anchor rod for mechanical anchoring of anti-buoyancy basement slab includes an anchor plate, a sleeve, and a rod body; the rod body is fixed to the center of the sleeve by a positioning bracket; and a concrete layer is placed between the sleeve and the rod body.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In the current basement anti-buoyancy projects, the anchoring methods of this device mostly adopt threaded anchors with concrete bonding or simple snap-on anchoring structures. Although these methods can meet the foundation anti-buoyancy requirements, they have defects in terms of anchoring stability, convenience of later maintenance, and adaptability to working conditions, making it difficult to cope with the long-term anti-buoyancy requirements of complex underground environments. Summary of the Invention

[0006] The purpose of this invention is to provide a high-strength anchor bolt for mechanical anchoring of anti-buoyancy basement slabs, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-strength anchor rod for mechanical anchoring of a basement anti-buoyancy bottom plate, comprising an anchor rod, a floating bottom plate and a fixing plate, wherein a fixing mechanism is provided on the anchor rod and the floating bottom plate, a limiting mechanism is provided on the floating bottom plate, and a plugging mechanism is provided on the floating bottom plate and the fixing plate;

[0008] The fixing mechanism includes threaded holes formed around the inside of the floating bottom plate. The anchor rod is threadedly connected to the threaded holes. A circular groove is formed at the top of the anchor rod. A first sliding groove is formed around the inner wall of the circular groove. An insert rod is inserted into the circular groove. A first sliding plate is fixedly connected to the surface of the insert rod. The surface of the first sliding plate is slidably connected to the inside of the first sliding groove. A handle is fixedly connected to the top of the insert rod. A top cover is provided at the top of the anchor rod. Insert plates are fixedly connected to the outer circumference of the top cover. Connecting seats are fixedly connected to the upper surface of the anchor rod. A slot is formed at the top of the connecting seat. The slot is inserted into the surface of the insert plate. A long groove is formed inside the outer side of the insert plate. A long block is inserted into the long groove. A connecting plate is fixedly connected to the outer side of the long block. Fixing rods are fixedly connected to both sides of the connecting seat. A rotating plate is rotatably connected to the surface of the fixing rod. Rectangular grooves are formed at both ends of the top of the connecting plate. Nuts are fixedly connected to both ends of the connecting plate. A screw is threadedly connected to the nuts and the rotating plate.

[0009] Preferably, the connecting seat has a through groove on the side away from the anchor rod, and the surface of the long block is inserted through the through groove on the side of the connecting seat away from the anchor rod.

[0010] Preferably, the top of the rectangular groove, the side away from the anchor rod, and the side near the anchor rod are set as openings, and the surface of the rotating plate is inserted into the inside of the rectangular groove.

[0011] Preferably, the connecting plate and the rotating plate have through-hole slots inside, and the screw is inserted through the through-hole slots inside the connecting plate and the rotating plate. The rotating plate is embedded in the rectangular slot, and the rotating plate, the connecting plate, the insert plate and the connecting seat are rigidly fixed together by the screw thread locking, so as to achieve a stable connection between the top cover and the anchor rod, and further strengthen the anchoring relationship between the anchor rod and the floating bottom plate.

[0012] Preferably, the limiting mechanism includes an elongated slot, which is formed around the top of the floating bottom plate. A connecting ring is fixedly connected to the upper surface of the anchor rod. An annular groove is formed on the outer ring of the connecting ring. Square slots are formed around the top of the floating bottom plate. Sliding grooves are formed at both ends of the bottom of the inner wall of the square slots. A slider is slidably connected inside the sliding groove. A movable seat is fixedly connected to the top of the two sliders. An arc-shaped block is fixedly connected to the side of the movable seat near the elongated slot. The surface of the arc-shaped block is inserted into the inside of the elongated slot. A spring is fixedly connected to the side of the movable seat away from the elongated slot. A telescopic rod is fixedly connected to the side of the movable seat away from the elongated slot.

[0013] Preferably, the other side of the spring and the telescopic rod are respectively fixedly connected to the inner wall of the square groove away from the long hole groove. The spring is sleeved on the surface of the telescopic rod. When the spring releases its elastic potential energy, it pushes the moving seat.

[0016] Preferably, the top and bottom of the square groove are set as openings, and the number of square blocks and square grooves are four in a group, with the surface of the square blocks and the inside of the square grooves being inserted together.

[0017] Preferably, the anchor rod surface and the insertion slot are inserted into each other, and there are four connecting seats and four second sliding plates, with the second sliding plate disposed on one side of the connecting seat.

[0018] Compared with the prior art, the present invention provides a high-strength anchor bolt for mechanical anchoring of basement anti-buoyancy bottom slabs, which has the following beneficial effects:

[0019] 1. This basement anti-buoyancy bottom slab anchor plate type mechanical anchoring high-strength anchor rod uses a fixing mechanism. The top cover is placed on top of the anchor rod, and the insertion plate is inserted into the slot to complete the initial connection between the top cover and the anchor rod. The top cover covers the round hole groove at the top of the anchor rod, which can prevent foreign objects such as dust, sand, and groundwater from entering the round hole groove, avoiding the accumulation of foreign objects that may prevent the insertion rod from being properly inserted or sliding later. Pushing the connecting plate drives the long block to be inserted into the long groove, initially restricting the insertion plate. Then, rotating the rotating plate makes the rotating plate embed into the rectangular groove, finally achieving a stable connection between the top cover and the anchor rod, while further strengthening the anchoring relationship between the anchor rod and the floating bottom slab.

[0020] 2. The high-strength anchor bolts of the anti-buoyancy bottom plate of this basement are mechanically anchored using a limiting mechanism. When the elastic potential energy of the spring is released, it pushes the moving seat. The moving seat drives the arc-shaped block to insert into the long hole groove, which restricts the movement of the anchor bolt. If the anchor bolt is affected by buoyancy or settlement and has a radial displacement tendency, the arc-shaped block will form a rigid block on the connecting ring. With the continuous thrust of the spring, it ensures that the anchor bolt always maintains the initial anchoring position and avoids cracking due to uneven stress on the floating bottom plate caused by displacement.

[0021] 3. The high-strength anchor rod of the anti-buoyancy basement slab is mechanically anchored by an anchor plate. Through the insertion mechanism, the insertion slot at the center of the fixing plate is aligned with the upper side of the anchor rod. The second sliding plate slides into the second sliding groove until the bottom of the fixing plate is in contact with the top of the floating basement slab. The block is inserted into the square groove to form the initial positioning of the floating basement slab and the base slab. The top block is held and aligned with the limiting groove and inserted to initially fix the position of the top block. Then the locking block is locked into the locking groove to rigidly fix the fixing plate and the floating basement slab, thereby improving the overall stability of the anti-buoyancy basement slab.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] This invention provides the following technical solutions: Example 1

[0035] Combination Figures 1 to 4 A mechanically anchored high-strength anchor rod for anti-buoyancy basement bottom plate includes an anchor rod 1, a floating bottom plate 2 and a fixing plate 6. A fixing mechanism 3 is provided on the anchor rod 1 and the floating bottom plate 2, a limiting mechanism 4 is provided on the floating bottom plate 2, and a plugging mechanism 5 is provided on the floating bottom plate 2 and the fixing plate 6.

[0036] The fixing mechanism 3 includes a threaded hole 309, which is formed around the inside of the floating bottom plate 2. The anchor rod 1 is threadedly connected to the threaded hole 309. A circular groove 307 is formed at the top of the anchor rod 1. A first sliding groove 308 is formed around the inner wall of the circular groove 307. An insert rod 33 is inserted into the circular groove 307. A first sliding plate 31 is fixedly connected to the four sides of the surface of the insert rod 33. The surface of the first sliding plate 31 is slidably connected to the inside of the first sliding groove 308. A handle 32 is fixedly connected to the top of the insert rod 33. A top cover 34 is provided at the top of the anchor rod 1. Insert plates 35 are fixedly connected to the four sides of the outer ring of the top cover 34. The upper surface of the anchor rod 1 has four... Each of the following is fixedly connected to a connecting seat 36. The top of the connecting seat 36 has a slot 305. The slot 305 is inserted into the surface of the insert plate 35. The outer side of the insert plate 35 has a long groove 304. A long block 306 is inserted into the long groove 304. A connecting plate 302 is fixedly connected to the outer side of the long block 306. Fixed rods 37 are fixedly connected to both sides of the connecting seat 36. A rotating plate 303 is rotatably connected to the surface of the fixed rods 37. Rectangular grooves 301 are opened at both ends of the top of the connecting plate 302. Nuts 39 are fixedly connected to both ends of the connecting plate 302. A screw 38 is threadedly connected to the nut 39 and the rotating plate 303.

[0037] The connecting seat 36 has a through groove on the side away from the anchor rod 1. The surface of the long block 306 is inserted through the through groove on the side of the connecting seat 36 away from the anchor rod 1. The top, the side away from the anchor rod 1, and the side close to the anchor rod 1 of the rectangular groove 301 are set as openings. The surface of the rotating plate 303 is inserted into the rectangular groove 301. The connecting plate 302 and the rotating plate 303 have through slots. The surface of the screw 38 is inserted through the through slots in the connecting plate 302 and the rotating plate 303.

[0038] Furthermore, the top cover 34 is placed on top of the anchor rod 1, and the insert plate 35 is inserted into the slot 305 to complete the initial docking between the top cover 34 and the anchor rod 1. The top cover 34 covers the round hole slot 307 at the top of the anchor rod 1, which can prevent foreign objects such as dust, sand, and groundwater from entering the round hole slot 307, and avoid the accumulation of foreign objects that may prevent the insert rod 33 from being inserted or sliding properly later. The connecting plate 302 is pushed to drive the long block 306 to be inserted into the long slot 304, which initially restricts the insert plate 35. Then, the rotating plate 303 is rotated so that the rotating plate 303 is embedded in the rectangular slot 301, and finally the top cover 34 and the anchor rod 1 are firmly connected, while further strengthening the anchoring relationship between the anchor rod 1 and the floating bottom plate 2. Example 2

[0039] See Figure 1-6Furthermore, based on Embodiment 1, the limiting mechanism 4 includes an elongated slot 45, which is opened around the top of the floating base plate 2. A connecting ring 47 is fixedly connected to the upper surface of the anchor rod 1. An annular sliding groove 46 is opened on the outer ring of the connecting ring 47. Square slots 43 are opened around the top of the floating base plate 2. Sliding grooves 401 are opened at both ends of the bottom of the inner wall of the square slot 43. A slider 49 is slidably connected inside the sliding groove 401. A movable seat 48 is fixedly connected to the top of the two sliders 49. An arc-shaped block 44 is fixedly connected to the side of the movable seat 48 near the elongated slot 45. The surface of the arc-shaped block 44 is inserted into the inside of the elongated slot 45. A spring 42 is fixedly connected to the side of the movable seat 48 away from the elongated slot 45. A telescopic rod 41 is fixedly connected to the side of the movable seat 48 away from the elongated slot 45.

[0040] The other side of the spring 42 and the telescopic rod 41 are respectively fixedly connected to the inner wall of the square groove 43 away from the long hole groove 45. The spring 42 is sleeved on the surface of the telescopic rod 41. The square grooves 43 are in pairs. The two square grooves 43 are respectively set on the left and right sides of the long hole groove 45. The two square grooves 43 and the long hole groove 45 are connected.

[0041] Furthermore, the spring 42 releases elastic potential energy, pushing the movable seat 48. The movable seat 48 drives the arc-shaped block 44 to insert into the elongated slot 45, restricting the movement of the anchor rod 1. If the anchor rod 1 is affected by buoyancy or settlement and has a radial offset tendency, the arc-shaped block 44 will form a rigid block on the connecting ring 47. With the continuous thrust of the spring 42, it ensures that the anchor rod 1 always maintains the initial anchor position, avoiding cracking due to uneven stress on the floating bottom plate 2 caused by offset. Example 3

[0042] See Figure 1-8 Furthermore, based on Embodiment 1, the insertion mechanism 5 includes an insertion slot 503, which is located at the center of the fixed plate 6. A second sliding groove 502 is provided around the inner wall of the insertion slot 503. A second sliding plate 501 is fixedly connected around the upper surface of the anchor rod 1. The surface of the second sliding plate 501 is slidably connected to the inside of the second sliding groove 502. A square groove 53 is provided around the inside of the fixed plate 6. A block 51 is densely fixedly connected around the top of the floating bottom plate 2. A limiting groove 52 is provided at the top of the block 51. The top of the limiting groove 52 is set as an opening. A limiting block 59 is inserted into the limiting groove 52. A top block 58 is fixedly connected to the top of the limiting block 59. A hinge block 57 is fixedly connected to both ends of the top block 58. A locking block 55 is hinged to the other side of the hinge block 57. A locking block 56 is fixedly connected to the side of the locking block 55 near the fixed plate 6. A locking groove 54 is densely provided around the fixed plate 6. The surface of the locking block 56 and the inside of the locking groove 54 are locked together.

[0043] The top and bottom of the square groove 53 are set as open. There are four square blocks 51 and four square grooves 53 in a group. The surface of the square block 51 is inserted into the inside of the square groove 53. The surface of the anchor rod 1 is inserted into the inside of the insertion slot 503. There are four connecting seats 36 and four second sliding plates 501. The second sliding plate 501 is set on one side of the connecting seat 36.

[0044] Furthermore, the insertion slot 503 at the center of the fixed plate 6 is aligned with the upper side of the anchor rod 1, and the second sliding plate 501 is slid into the second sliding groove 502 until the bottom of the fixed plate 6 is in contact with the top of the floating bottom plate 2. The block 51 is inserted into the square groove 53 to form the initial positioning of the floating bottom plate and the bottom plate. The top block 58 is held and inserted into the limiting groove 52 to initially fix the position of the top block 58. Then the locking block 56 is inserted into the locking groove 54 to rigidly fix the fixed plate 6 and the floating bottom plate 2, thereby improving the overall stability of the basement anti-floating bottom plate.

[0045] In actual operation, when this device is used, the multi-step mechanical locking of the fixing mechanism 3 ensures the stable anchoring of the anchor rod 1 after it has penetrated deep into the ground. Simultaneously, the top cover 34 provides protection, ensuring that the subsequent disassembly or adjustment of the anchor rod is not disturbed by foreign objects. First, align the anchor rod 1 with the threaded holes 309 around the inside of the floating base plate 2. Insert the insertion rod 33 into the circular slot 307, and slide the first sliding plate 31 into the first sliding groove 308. Rotate the handle 32 until the anchor rod 1 is threadedly engaged with the threaded hole 309, gradually penetrating the underground soil layer until the lower end of the anchor rod 1 is completely anchored in the stable foundation. At this point, the floating base plate 2 is initially fixed to the anchor rod 1 through the threaded engagement, forming a foundation anti-buoyancy connection. Then, remove the insertion rod 33 from the circular slot 307, and place the top cover 34 on the anchor. At the top of the rod 1, the insert plate 35 is inserted into the slot 305, completing the initial docking of the top cover 34 and the anchor rod 1. The top cover 34 covers the round hole slot 307 at the top of the anchor rod 1, which can prevent foreign objects such as dust, sand, and groundwater from entering the round hole slot 307, avoiding the accumulation of foreign objects that may prevent the insert rod 33 from being inserted or sliding properly later. The connecting plate 302 is pushed to drive the long block 306 to be inserted into the long slot 304, initially restricting the insert plate 35. Then, the rotating plate 303 is rotated so that the rotating plate 303 is embedded in the rectangular slot 301. Through the threaded locking of the screw 38, the rotating plate 303, the connecting plate 302, the insert plate 35 and the connecting seat 36 are rigidly fixed as one, finally realizing the stable connection between the top cover 34 and the anchor rod 1, and further strengthening the anchoring relationship between the anchor rod 1 and the floating bottom plate 2.

[0046] After the anchor rod 1 is initially anchored, the elastic drive of the limiting mechanism 4 and the arc-shaped block limit prevent the anchor rod 1 from radially shifting due to groundwater buoyancy and slight foundation settlement, ensuring the stability of the anchoring position. The elastic potential energy can be released by the spring 42 to push the moving seat 48 to slide along the slide groove 401, providing guidance for the movement and preventing the spring 42 from deforming and shifting. The moving seat 48 drives the arc-shaped block 44 to move synchronously until the arc-shaped block 44 is inserted into the long hole groove 45 and tightly fits with the annular slide groove 46 on the outer ring of the connecting ring 47. The cooperation between the arc-shaped block 44 and the annular slide groove 46 restricts the movement of the anchor rod 1. If the anchor rod 1 is affected by buoyancy or settlement and has a radial shift tendency, the arc-shaped block 44 will form a rigid block on the connecting ring 47. With the continuous thrust of the spring 42, the anchor rod 1 is ensured to always maintain the initial anchoring position, avoiding cracking of the floating bottom plate 2 due to uneven stress caused by the shift.

[0047] Align the insertion slot 503 at the center of the fixing plate 6 with the upper side of the anchor rod 1. The second sliding plate 501 slides into the second sliding groove 502 until the bottom of the fixing plate 6 is in contact with the top of the floating bottom plate 2. At this time, the square groove 53 is just aligned with the block 51. The block 51 is inserted into the square groove 53 to form the initial positioning of the floating bottom plate and the bottom plate. Hold the top block 58 and insert it into the limiting groove 52 to initially fix the position of the top block 58. Then move the locking block 55 so that the locking block 55 drives the locking block 56 to be locked into the locking groove 54, which can rigidly fix the fixing plate 6 and the floating bottom plate 2 and improve the overall stability of the basement anti-floating bottom plate.
