Description

Technical Field

[0001] This utility model relates to the field of anchorages, and in particular to a quick-release prestressed anchorage with a self-locking function. Background Technology

[0002] Prestressed anchorages are the core components of prestressed concrete structures. Their function is to safely and reliably permanently anchor high-strength steel strands or reinforcing bars (called prestressed tendons) after tensioning, and effectively transfer the huge tensile force that these tendons bear to the concrete structure. This gives the concrete critical prestress, improves the structure's crack resistance, stiffness, and load-bearing capacity, and is a key guarantee for modern bridges, large buildings, and other engineering projects.

[0003] The applicant found through a search that a Chinese patent discloses "a type of slow-bonding prestressed anchor" with publication number "CN220978569U". This patent mainly uses a guide component to allow rollers to abut against and roll with the prestressing tendon, thereby reducing the friction between the prestressing tendon and the inner wall of the tapered hole. This makes it easier for installers to guide the prestressing tendon through the tapered hole, reducing the complexity and difficulty of the installation operation. Furthermore, when the prestressing tendon retracts in the direction of extending into the tapered hole, the prestressing tendon drives multiple connecting plates to move closer to each other, which can clamp the prestressing tendon and ensure the connection strength between the prestressing tendon and the sleeve.

[0004] The aforementioned device can reduce the difficulty and complexity of installation for workers through a series of structural designs. However, in actual use, after the clips are installed at the corresponding positions of the conical holes, the device lacks an effective fixing mechanism. This makes the clips prone to falling off under external influences, thus affecting the construction quality. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-release prestressed anchor with a self-locking function to solve the problem mentioned in the background art that the above-mentioned device cannot effectively fix the clamping plate during use, which leads to the clamping plate easily falling off.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release prestressed anchor with self-locking function, comprising an anchor plate and a body, wherein four connecting plates are fixedly connected to one side of the body, and one side of each of the four connecting plates is fixedly connected to one side of the surface of the anchor plate by bolts. A plurality of fixing holes are provided on one side of the surface of the body, and a fixing clip is provided inside each fixing hole. A limiting component is provided inside each fixing hole, and a self-locking component is provided on each fixing clip and inside the corresponding fixing hole.

[0007] Preferably, the limiting component includes two limiting vertical grooves, which are respectively formed on both sides of the inner wall of the corresponding fixing hole.

[0008] Preferably, the limiting component further includes two annular grooves, both of which are formed on both sides of the inner wall of the corresponding fixing hole, and both of which communicate with the corresponding limiting vertical groove.

[0009] Preferably, the limiting component further includes two rectangular limiting blocks, one side of the surface of each rectangular limiting block is fixedly connected to one side of the surface of the corresponding fixing clip, and each rectangular limiting block is matched with the corresponding annular groove and the limiting vertical groove.

[0010] Preferably, the self-locking assembly includes two auxiliary slots and two control blocks. The two auxiliary slots are each formed on one side of the surface of the corresponding fixing clip, and the bottom surface of the two control blocks is fixedly connected to the top surface of the corresponding fixing clip.

[0011] Preferably, the self-locking assembly further includes two self-locking circular blocks and two fixing slots. One side of the surface of each self-locking circular block is fixedly connected to one side of the surface of the corresponding rectangular limiting block. Each fixing slot is respectively opened on one side of the inner wall of the corresponding annular groove. Each self-locking circular block matches the corresponding fixing slot.

[0012] Preferably, each of the fixing holes and fixing clips is conical, and each of the fixing clips matches the corresponding fixing hole.

[0013] Preferably, a sleeve is fixedly connected to one side of the surface of the anchor plate, and a spiral rib is sleeved on the surface of the sleeve, with one end of the spiral rib fixedly connected to one side of the surface of the anchor plate.

[0014] The technical effects and advantages of this utility model are as follows: By setting a limiting component in the fixing hole, this utility model ensures that the fixing clip can be accurately installed in place. At the same time, with the design of the self-locking component, the clip is automatically locked after it is installed in place. This structure not only ensures the stability of the fixing clip installation, but also realizes the function of quick disassembly. Attached Figure Description

[0022] Example 1

[0023] like Figures 1 to 5 As shown, a quick-release prestressed anchor with self-locking function in the first aspect embodiment of the present invention includes an anchor plate 1 and a body 6. Four connecting plates 7 are fixedly connected to one side of the body 6. One side of each of the four connecting plates 7 is fixedly connected to one side of the surface of the anchor plate 1 by bolts. A plurality of fixing holes 9 are provided on one side of the surface of the body 6. Each fixing hole 9 is provided with a fixing clip 8 inside. Each fixing hole 9 is provided with a limiting component 2 inside. Each fixing clip 8 and the corresponding fixing hole 9 are provided with a self-locking component 3.

[0024] The technical effect achieved by the above embodiment is as follows: by setting the limiting component 2 in the fixing hole 9, it is ensured that the fixing clip 8 can be accurately installed in place. At the same time, with the design of the self-locking component 3, it automatically locks the clip after it is installed in place. This structure not only ensures the installation stability of the fixing clip 8, but also realizes the function of quick disassembly.

[0025] Example 2

[0026] like Figures 2 to 4As shown, a quick-release prestressed anchor with self-locking function includes all the contents of Embodiment 1. In addition, the limiting component 2 includes two limiting vertical grooves 201, which are respectively opened on both sides of the inner wall of the corresponding fixing hole 9. The limiting component 2 also includes two annular grooves 203, which are both opened on both sides of the inner wall of the corresponding fixing hole 9 and are connected to the corresponding limiting vertical grooves 201. The limiting component 2 also includes two rectangular limiting blocks 202, one side of the surface of each rectangular limiting block 202 is fixedly connected to one side of the surface of the corresponding fixing clip 8, and each rectangular limiting block 202 matches the corresponding annular groove 203 and the limiting vertical groove 201.

[0027] The technical effect achieved by the above embodiment is as follows: When installing the fixing clip 8, first align the two rectangular limiting blocks 202 on the fixing clip 8 with the two limiting vertical grooves 201 inside the corresponding fixing hole 9 and insert them into the fixing hole 9. Then, by rotating the fixing clip 8, the two rectangular limiting blocks 202 are moved to the corresponding annular groove 203. After the two rectangular limiting blocks 202 are moved into the annular groove 203, the fixing clip 8 can be locked and limited by the self-locking component 3, which ensures the stability of the installation of the fixing clip 8.

[0028] Example 3

[0029] like Figure 3 and Figure 5 As shown, a quick-release prestressed anchor with self-locking function includes all the contents of Embodiment 2.
