Description

Technical Field

[0001] This utility model relates to the field of anchor assembly technology, specifically to an anchor assembly that can be quickly disassembled. Background Technology

[0002] Anchor assemblies, as core load-bearing components in prestressed engineering, are primarily used to fix prestressing tendons and transfer the prestress generated during tensioning to concrete members, thereby improving the member's load-bearing capacity, crack resistance, and durability. They are widely used in large-scale infrastructure construction fields such as highway bridges, railway engineering, high-rise buildings, and water conservancy projects. During prestressed construction, anchor assemblies must work in conjunction with tensioning equipment to complete the "tensioning-anchoring" process. In some scenarios, anchor assemblies also need to be disassembled; their disassembly efficiency and ease of operation directly affect project progress, construction costs, and member safety.

[0003] For example, Chinese utility model patent application number 202321090452.4 discloses a detachable steel structure anchor. By setting a connecting component, when the left and right halves of the anchor need to be used together, the insert plate at one end of the left half is inserted into the slot of the right half. When the insert plate contacts the locking block, the insert plate pushes the locking block into the cavity, and simultaneously the locking block pushes the sliding rod, compressing the spring. When the slot at one end of the insert plate aligns with the locking block, the spring extends and pushes the locking block into the slot of the insert plate, limiting the insertion plate and thus achieving the effect of limiting and fixing the left and right halves of the anchor. The connecting component facilitates the quick assembly and disassembly of the left and right halves, improving the practicality of the device. However, this device still has certain shortcomings. While using the elastic force of a spring to connect and fix two anchors simplifies the structural complexity of traditional threaded or pin-fixed anchors and reduces the difficulty of initial assembly, in actual prestressed engineering applications, the anchors are subjected to large forces, resulting in obvious performance defects and safety hazards, making it difficult to meet the requirements for long-term stable anchoring.

[0004] Therefore, we propose a quick-detachable anchor assembly to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a quick-disassembly anchor assembly to solve the problem mentioned in the background art. Currently, the connection and fixation of two anchors by the elastic force of springs can simplify the structural complexity of traditional thread or pin fixing and reduce the initial assembly difficulty. However, in actual prestressed engineering applications, the anchors are subjected to large forces, resulting in obvious performance defects and safety hazards, and making it difficult to meet the requirements of long-term stable anchoring.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick-disassembly anchor assembly, comprising a first anchor assembly and a second anchor assembly, wherein the second anchor assembly is disposed on the right side of the first anchor assembly, and both the first and second anchor assemblies are provided with through holes; snap-fit ​​blocks are installed on both the left and right sides of the front surface of the second anchor assembly; first connecting blocks are installed on both the left and right sides of the first anchor assembly; second connecting blocks are installed on both the left and right sides of the second anchor assembly; and grooves are provided on both the left and right sides of the second connecting blocks, wherein connecting strips are installed on the grooves. The front surface of each connecting strip is provided with an internal groove, and a reverse threaded rod is installed inside the internal groove through a bearing seat. The reverse threaded rod is sequentially installed with a first movable plate and a second movable plate from top to bottom, and a positioning block is installed on the opposite side of the first movable plate and the second movable plate.

[0007] Preferably, the first anchor assembly has locking grooves on both the left and right rear sides, and magnetic blocks are installed inside the locking grooves.

[0008] With the above structural design, the snap-fit ​​grooves on the left and right sides of the rear of the first anchor assembly provide space for the snap-fit ​​block. The magnetic blocks installed in the grooves can generate magnetic force, forming a preliminary magnetic attraction positioning when the snap-fit ​​block is inserted, providing a precise foundation for the subsequent fixing of the connecting strip and the limiting component, and preventing the first anchor assembly and the second anchor assembly from shifting during the assembly process.

[0009] Preferably, the snap-fit ​​block on the second anchor assembly snaps into the snap-fit ​​groove, and the snap-fit ​​block is magnetically connected to the magnetic block.

[0010] With the above structural design, the snap-fit ​​block on the second anchor assembly is inserted into the snap-fit ​​groove of the first anchor assembly, and the displacement of the two anchor assemblies is restricted by mechanical snap-fit; at the same time, the snap-fit ​​block is magnetically connected to the magnetic block in the snap-fit ​​groove, which enhances the stability of the initial fixation, prevents the two components from accidentally separating during the assembly process, and creates conditions for subsequent strengthening fixation.

[0011] Preferably, each of the first connecting blocks has a through groove, the connecting strip passes through the through groove, and a limit component is installed on the connecting strip.

[0012] With the above structural design, the through groove on the first connecting block allows the connecting strip on the groove of the second connecting block to pass through, so that the first anchor assembly and the second anchor assembly are connected by the connecting strip.

[0013] Preferably, the limiting component abuts against the first connecting block, and the limiting component and the first connecting block are magnetically connected.

[0014] With the above structural design, the limiting component abuts against the first connecting block, and at the same time, the limiting component and the first connecting block are magnetically connected, which further enhances the fixing effect of the limiting component, prevents it from falling off when subjected to external force or vibration, and ensures that the connecting strip fixes the two anchor components continuously and effectively.

[0015] Preferably, a guide rod is installed inside the built-in groove. The guide rod is parallel to the reverse threaded rod, and both the first movable plate and the second movable plate are slidably connected to the guide rod.

[0016] With the above structural design, the guide rod and the reverse threaded rod inside the groove of the connecting strip are parallel to each other. When the reverse threaded rod is rotated, the first movable plate and the second movable plate slide along the guide rod, which restricts the movement trajectory of the movable plate and prevents the movable plate from shifting or getting stuck as the reverse threaded rod rotates. This ensures that the two movable plates drive the positioning block to move synchronously and stably in opposite directions, ensuring accurate anchoring position.

[0017] Preferably, the connecting strip has limit grooves on both the upper and lower sides, the positioning block passes through the limit groove, and the positioning block is slidably connected to the limit groove.

[0018] With the above structural design, the limiting grooves on the upper and lower sides of the connecting strip provide sliding channels for the positioning block. When the first movable plate and the second movable plate move in opposite directions, the positioning block slides along the limiting groove and extends out of the connecting strip, so that the positioning block extends out and engages with the first connecting block on the first anchor assembly, thereby realizing the connection between the first anchor assembly and the second anchor assembly and meeting the long-term stable anchoring requirements under the high stress scenario of prestressed engineering.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the quick-detachable anchor assembly: 1. Strong anchoring stability, suitable for high-stress scenarios Abandoning the traditional spring-force fixing method, a multi-layered structure of "mechanical snap-fit ​​+ magnetic positioning + rigid anchoring" is adopted to ensure stability: the snap-fit ​​block of the second anchor component mechanically snaps into the snap-fit ​​groove of the first anchor component, and magnetic positioning with a magnetic block achieves initial fixation; the connecting strip passes through the through groove of the first connecting block, and the limiting component abuts against the first connecting block and magnetically attracts it, strengthening the connection; rotating the reverse threaded rod drives the first movable plate and the second movable plate to move in opposite directions, causing the positioning block to extend along the limiting groove and snap into the first connecting block, forming a rigid anchoring point, which can withstand the large forces in prestressed engineering, avoid the safety hazards caused by spring failure, and meet the requirements for long-term stable anchoring; 2. Easy and efficient assembly and disassembly, reducing project costs. Assembly requires only three steps: "clamping and positioning - penetrating the connecting strip - rotating the threaded rod for anchoring." No complicated tools are needed to quickly connect the first and second anchor components. To disassemble, rotate the reverse threaded rod in the opposite direction to retract the positioning block, release the magnetic attraction of the limiting component, and pull out the connecting strip to separate the two components. The operation is simple and efficient. Attached Figure Description

The limiting component 12 abuts against the first connecting block 7 and is magnetically connected to the first connecting block 7. The limiting component 12 abuts against the first connecting block 7 and is magnetically connected to the first connecting block 7, which further enhances the fixing effect of the limiting component 12 and prevents it from falling off when subjected to external force or vibration, ensuring that the connecting strip 11 is continuously and effectively fixed to the two anchor assemblies.

[0024] The front surface of the connecting strip 11 is provided with an internal groove 13, and a reverse threaded rod 14 is installed inside the internal groove 13 via a bearing seat. A first movable plate 15 and a second movable plate 16 are sequentially installed on the reverse threaded rod 14 from top to bottom.

A guide rod 18 is installed inside the internal groove 13, and the guide rod 18 is parallel to the reverse threaded rod 14. Both the first movable plate 15 and the second movable plate 16 are slidably connected to the guide rod 18. When the reverse threaded rod 14 is rotated, the first movable plate 15 and the second movable plate 16 slide along the guide rod 18, restricting the movement trajectory of the movable plates and avoiding... The movable plate is prevented from shifting or jamming as it rotates with the reverse threaded rod 14, ensuring that the two movable plates drive the positioning block 17 to move synchronously and stably in opposite directions, thus ensuring accurate anchoring position.

When the first movable plate 15 and the second movable plate 16 move in opposite directions, the positioning block 17 slides along the limiting groove 19 and extends out of the connecting strip 11, so that the positioning block 17 extends out and engages with the first connecting block 7 on the first anchor assembly 1, realizing the connection between the first anchor assembly 1 and the second anchor assembly 2, and meeting the long-term stable anchoring requirements under the high stress scenario of prestressed engineering.

[0025] Working principle: When using this quick-disassembly anchor assembly, firstly, insert the snap-fit ​​blocks 4 on the left and right sides of the front surface of the second anchor assembly 2 into the snap-fit ​​grooves 5 on the left and right sides of the rear side of the first anchor assembly 1. The snap-fit ​​blocks 4 and the magnetic blocks 6 in the snap-fit ​​grooves 5 are magnetically connected. Through the dual action of mechanical snap-fit ​​and magnetic force, the initial positioning and fixation of the two anchor assemblies are achieved, avoiding displacement during the assembly process.

[0026] Meanwhile, the connecting strips 11 on the left and right sides of the second anchor assembly 2 pass through the through grooves 8 of the first connecting blocks 7 on the left and right sides of the first anchor assembly 1, so that the connecting strips 11 span the two anchor assemblies; the limiting assembly 12 is in close contact with the first connecting block 7, and at the same time, the limiting assembly 12 is magnetically connected to the first connecting block 7, further fixing the connecting strips 11 and preventing them from loosening in the through grooves 8.

[0027] Rotate the reverse threaded rod 14 in the built-in groove 13 on the front surface of the rotating connecting bar 11. When the reverse threaded rod 14 rotates, the first movable plate 15 and the second movable plate 16 installed on it slide in the opposite direction along the guide rod 18 in the built-in groove 13. When the first movable plate 15 and the second movable plate 16 move in the opposite direction, they drive the positioning block 17 on their respective opposite sides to slide along the limiting groove 19 on the upper and lower sides of the connecting bar 11 and extend out of the connecting bar 11. The positioning block 17 is engaged with the first connecting block 7 to form a rigid anchor point, thus completing the stable connection of the two anchor components. The prestressed tendons can be inserted through the through hole 3 for tensioning and anchoring.

[0028] If disassembly is required, first rotate the reverse threaded rod 14 in the opposite direction, causing the first movable plate 15 and the second movable plate 16 to drive the positioning block 17 back along the limiting groove 19 into the connecting strip 11, thus releasing the engagement with the first connecting block 7; then separate the magnetic attraction between the limiting component 12 and the first connecting block 7, and pull the connecting strip 11 out of the through groove 8; overcome the magnetic force of the magnet 6, and remove the locking block 4 of the second anchor assembly 2 from the locking groove 5 of the first anchor assembly 1, thereby completing the disassembly of the two anchor assemblies and completing a series of operations.
