Description

Technical Field

[0001] This utility model relates to the field of prestressed anchor technology, and in particular to a fine-tuning anchor capable of compensating for prestress loss. Background Technology

[0002] In fields such as civil engineering, bridge construction, and installation of large structural components, prestressed anchors are key components to ensure structural stability and safety. They apply prestress through methods such as pre-tightening bolts or wedge plugs and maintain this prestressed state during long-term use to resist deformation caused by external loads.

[0003] However, existing prestressed anchorages are inconvenient to adjust for changes in prestress during use, making them inconvenient to use. Therefore, a fine-tuning anchorage that can compensate for prestress loss is needed. Utility Model Content

[0004] The purpose of this invention is to provide a fine-tuning anchor that can compensate for prestress loss, which solves the problem that existing prestressed anchors are inconvenient to adjust for changes in prestress during use, and are not convenient to use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fine-tuning anchor with prestress loss compensation, comprising a fixed plate and an anchor mechanism installed inside the fixed plate, wherein the anchor mechanism comprises an installation component and a fixing component;

[0006] The mounting assembly includes an end plate, a tapered hole, a first clamping piece, a second clamping piece, a front reinforcing bar, a plate cavity, and a constant groove. The fixing plate has a plate cavity inside, and the end plate is installed inside the plate cavity. The end plate has multiple sets of tapered holes arranged in an array inside, and the first clamping piece is installed inside the tapered hole. The second clamping piece is symmetrically arranged at the other end of the first clamping piece. The front reinforcing bar is installed inside the first and second clamping pieces. The constant groove is formed on the outer surface of both the first and second clamping pieces.

[0007] The fixing component includes a pouring hole, a connector, a spiral rib, and a limiting cavity. Pouring holes are provided at all four corners of the fixing plate. A connector is fixedly installed on the right side of the fixing plate. A spiral rib is welded to the right side of the connector. A limiting cavity is provided on the right side of the plate cavity.

[0008] Preferably, the end plate and the fixed plate are sized to match each other through the plate cavity, and the end plate and the plate cavity are detachable.

[0009] Preferably, the tapered hole has a tapered structure, the dimensions of the first clip and the second clip match each other, and the first clip and the second clip are symmetrical to each other.

[0010] Preferably, the constant groove array is formed on the outer surfaces of the first clip and the second clip, which are also referred to as tapered structures.

[0011] Preferably, the disc cavity and the limiting cavity are interconnected, and the connection between the disc cavity and the limiting cavity is an arc-shaped structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] During use, the end plate can be installed together with the fixed plate through the plate cavity. After the steel cable is fixed inside the end plate during installation, the angle inside the plate cavity can be adjusted. At the same time, if prestress loss or change is detected during the use of the device, the prestress of the device can be adjusted by adjusting the direction and contact position between the end plate and the plate cavity.

[0014] During use, the tapered hole, with its tapered structure, can fix the positions of the first and second clamping pieces. Threads are also provided inside the tapered hole. The steel cable is then placed between the first and second clamping pieces, which are then fixed inside the tapered hole. The steel cable, under its own weight, pulls the first and second clamping pieces to the right. The constant-thread grooves on the outside of the first and second clamping pieces increase the friction with the tapered hole, thereby improving the efficiency of fixing the front reinforcing bar and making the device more stable.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1-4 As shown in the figure, a fine-tuning anchor with prestress loss compensation includes a fixed plate 1 and an anchor mechanism installed inside the fixed plate 1. The anchor mechanism includes an installation component and a fixing component.

[0024] The mounting assembly includes an end plate 3, a tapered hole 4, a first clamping piece 5, a second clamping piece 6, a front reinforcing bar 7, a plate cavity 10, and a constant groove 12. The plate cavity 10 is opened inside the fixing plate 1, and the end plate 3 is installed inside the plate cavity 10. Multiple sets of tapered holes 4 are arrayed inside the end plate 3. The first clamping piece 5 is installed inside the tapered hole 4. The second clamping piece 6 is symmetrically arranged at the other end of the first clamping piece 5. The front reinforcing bar 7 is installed inside the first clamping piece 5 and the second clamping piece 6. The constant groove 12 is opened on the outer surface of both the first clamping piece 5 and the second clamping piece 6.

[0025] The fixing component includes a pouring hole 2, a connector 8, a spiral rib 9, and a limiting cavity 11. A pouring hole 2 is provided at each of the four corners of the fixing plate 1. A connector 8 is fixedly installed on the right side of the fixing plate 1. A spiral rib 9 is welded to the right side of the connector 8. A limiting cavity 11 is provided on the right side of the plate cavity 10.

[0026] The end plate 3 and the fixed plate 1 are sized to match each other through the plate cavity 10. The end plate 3 and the plate cavity 10 are detachable. During use, the end plate 3 can be installed together with the fixed plate 1 through the plate cavity 10. After the steel cable is fixed inside the end plate 3 during installation, the angle inside the plate cavity 10 can be adjusted. At the same time, if the prestress loss or change is detected during the use of the device, the prestress of the device can be adjusted by adjusting the direction and contact position between the end plate 3 and the plate cavity 10.

[0027] The conical hole 4 has a conical structure, and the dimensions of the first clamping piece 5 and the second clamping piece 6 are matched. The first clamping piece 5 and the second clamping piece 6 are symmetrical to each other. During use, the conical structure of the conical hole 4 can fix the position of the first clamping piece 5 and the second clamping piece 6. At the same time, a thread is opened inside the conical hole 4. Then, the steel cable is placed between the first clamping piece 5 and the second clamping piece 6, and then the first clamping piece 5 and the second clamping piece 6 are fixedly installed inside the conical hole 4. Then, the steel cable will pull the first clamping piece 5 and the second clamping piece 6 to the right by its own weight. Then, the constant thread groove 12 opened on the outside of the first clamping piece 5 and the second clamping piece 6 will increase the friction with the conical hole 4, thereby improving the efficiency of the device in fixing the front steel bar 7, thus making the device more stable.

[0028] The constant groove 12 array is formed on the outer surface of the first clamping piece 5 and the second clamping piece 6. The first clamping piece 5 and the second clamping piece 6 are also called conical structures. During use, the constant groove 12 array is formed on the outer surface of the first clamping piece 5 and the second clamping piece 6, so that when the first clamping piece 5 and the second clamping piece 6 are installed inside the end plate 3, the friction between the first clamping piece 5 and the second clamping piece 6 and the conical hole 4 can be increased, thereby improving the stability of the device and facilitating its use.

[0029] Example 2

[0030] like Figure 4 As shown, this embodiment further illustrates Example 1. The disc cavity 10 and the limiting cavity 11 are interconnected. The connection between the disc cavity 10 and the limiting cavity 11 is an arc-shaped structure. During use, the front reinforcing bar 7 can be placed inside the disc cavity 10 and the limiting cavity 11, which facilitates the protection of the device and the filling of cement into the device. Furthermore, the arc-shaped connection between the disc cavity 10 and the limiting cavity 11 prevents damage to the front reinforcing bar 7 at the corner when it is installed inside the device, thus avoiding breakage of the front reinforcing bar 7 during use.

[0031] Working principle: First, the front reinforcing bar 7 is fixed by the first clamp 5 and the second clamp 6. The conical hole 4 has a conical structure to fix the position of the first clamp 5 and the second clamp 6. At the same time, threads are opened inside the conical hole 4. Then, the steel cable is placed between the first clamp 5 and the second clamp 6. Then, the first clamp 5 and the second clamp 6 are fixed inside the conical hole 4. Then, the steel cable will pull the first clamp 5 and the second clamp 6 to the right by its own weight. Then, the constant thread groove 12 opened on the outside of the first clamp 5 and the second clamp 6 will increase the friction with the conical hole 4, thereby improving the efficiency of the device in fixing the front reinforcing bar 7, thus making the device more stable. The disc cavity 10 and the limiting position The cavity 11 can accommodate the front reinforcing bar 7, which facilitates the protection of the device and the filling of cement. The connection between the disc cavity 10 and the limiting cavity 11 is an arc-shaped structure, which prevents damage to the front reinforcing bar 7 at the corner when it is installed into the device, thus preventing the front reinforcing bar 7 from breaking during use. Finally, the end plate 3 can be installed together with the fixed plate 1 through the disc cavity 10. After the steel cable is fixed inside the end plate 3 during installation, the angle inside the disc cavity 10 can be adjusted. At the same time, if the prestress loss or change is detected during the use of the device, the prestress of the device can be adjusted by adjusting the direction and contact position between the end plate 3 and the disc cavity 10.
