Description

Technical Field

[0001] The utility model relates to the field of road and bridge engineering, in particular to an anchor for road and bridge engineering. Background Art

[0002] At present, a Chinese utility model with the announcement number CN213448101U discloses an anchor for road and bridge engineering, including an anchor body, a mounting hole is provided on the surface of the anchor body, a stress rib is penetrated through the inner cavity of the mounting hole, a protective sleeve used in conjunction with the stress rib is fixedly connected to the inner cavity of the mounting hole, a protective coating is applied on the surface of the protective sleeve, a first anti-rust coating is applied on the surface of the anchor body, and a fixing device is provided on the surface of the stress rib. The utility model can achieve the function of good use effect through the anchor body, the fixing device, the stress rib, the first anti-rust coating, the mounting hole, the protective sleeve, the protective coating, the fixing bolt, the through hole, the fixing nut, the fixing arc, the second anti-rust coating and the wear-resistant coating, and solves the problem that the anchor for road and bridge engineering in the existing market does not have the function of good use effect, is prone to rust during use and affects use, has serious wear phenomenon under stress during use, and is not conducive to long-term use by users.

[0003] The existing anchors cannot press the clips tightly. The clips of general anchors are conical. When the prestressed tendons are tensioned, the movement of the steel strands will drive the clips to move, causing the clips to separate from the clip holes on the anchor plate. When returning to the top, the prestressed tendons shrink, causing the clips to follow the prestressed tendons into the interior of the anchor plate. The positions of the clips and the prestressed tendons have not changed, resulting in a poor fixing effect. Tools are needed to fix the clips and then return to the top, which is very troublesome and inconvenient to use. It is also inconvenient to connect the grouting pipes. When grouting the holes, the grouting pipes need to be connected to the grouting holes on the anchor pad, and the grouting holes and the grouting pipes are generally connected by threads. During installation and disassembly, tools are needed to install and disassemble them. The connection process is relatively cumbersome, which increases the workload and reduces the work efficiency. In order to solve the above-mentioned problems, we propose an anchor for road and bridge engineering. Utility Model Content

[0004] The utility model aims to provide an anchor for road and bridge engineering, which has the advantages of being able to press the clamping piece and being convenient for connecting the grouting pipe.

[0005] The above-mentioned technical objective of the utility model is achieved through the following technical solutions: an anchor for road and bridge engineering, comprising an anchor plate, an anchor plate is arranged between the inner walls of the anchor plate, a clip is arranged on the inner wall of the anchor plate, a fixing frame is bolted on the surface of the anchor plate, a limiting plate is integrally formed on the surface of the clip, a first spring is arranged between the limiting plate and the inner wall of the fixing frame, and the first spring is sleeved on the surface of the clip, a threading hole is opened on the surface of the fixing frame, a joint pipe is connected to the surface of the anchor plate, a connecting head is slidably sleeved on the surface of the joint pipe, a grouting pipe is connected to the surface of the connecting head, a sliding sleeve is slidably sleeved on the surface of the connecting head, a second spring is sleeved on the surface of the connecting head, a connecting rod is hinged on the inner wall of the sliding sleeve, a sliding rod is hinged on the other end of the connecting rod, and the sliding rod is slidably connected to the inner wall of the connecting head, a clamping joint is bolted on the surface of the sliding rod, a third spring is arranged between the sliding rod and the inner wall of the connecting head, a clamping groove is opened on the surface of the joint pipe, and the clamping groove is clamped with the clamping joint.

[0006] By adopting the above technical scheme, when the prestressed tendon is tensioned, the movement of the prestressed tendon drives the clamp to move. Under the action of the first spring, the clamp will not move with the prestressed tendon. When returning to the top or releasing the tension, the prestressed tendon can be quickly fixed without shrinking the prestressed tendon, thereby ensuring the stability of the prestress, thereby achieving the purpose of pressing the clamp, ensuring the stability of the clamp, and facilitating use. By moving the sliding sleeve, the connecting rod drives the sliding rod to move the card joint and disengage it from the card groove, and then separate the connecting head from the connecting pipe to complete the disassembly. During installation, insert the connecting pipe into the connecting head, loosen the sliding sleeve, and the sliding sleeve is reset under the action of the second spring. The sliding rod drives the card joint to engage with the card groove under the action of the third spring to fix it and complete the installation, thereby achieving the purpose of facilitating the connection of the grouting pipe, reducing the workload and improving the work efficiency.

[0007] The utility model is further configured as follows: spiral ribs are sleeved on the surface of the anchor plate.

[0008] By adopting the above technical solution, spiral reinforcement is provided to improve the compressive strength of the concrete behind the anchor, thereby preventing local damage to the concrete under the anchor under the action of tensile stress.

[0009] The utility model is further configured as follows: a first sealing ring is arranged between the anchor pad and the anchor plate.

[0010] By adopting the above technical solution, the first sealing ring is provided to prevent slurry leakage.

[0011] The utility model is further configured as follows: a rubber ring is fixedly sleeved on the surface of the clip.

[0012] By adopting the above technical solution, a rubber ring is provided to clamp the clip and the prestressed tendon, thereby increasing the friction force.

[0013] The utility model is further configured as follows: the surface of the sliding sleeve is provided with anti-slip grooves.

[0014] By adopting the above technical solution, anti-skid patterns are provided to prevent hands from slipping and facilitate operation.

[0015] The utility model is further configured as follows: one end of the clamping joint is wedge-shaped.

[0016] By adopting the above technical solution, one end of the card connector is set to be wedge-shaped, which is convenient for connection.

[0017] The utility model is further configured as follows: a second sealing gasket is arranged between the joint pipe and the inner wall of the connecting head.

[0018] By adopting the above technical solution, a second sealing ring is provided to prevent slurry leakage.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model, when the prestressed tendons are tensioned, the movement of the prestressed tendons drives the movement of the clips, and the clips will not move with the prestressed tendons under the action of the first spring. When the prestressed tendons are returned to the top or released, the prestressed tendons can be quickly fixed without shrinking the prestressed tendons, thereby ensuring the stability of the prestress, thereby achieving the purpose of pressing the clips, ensuring the stability of the clips, and facilitating use;

[0021] 2. The utility model moves the sliding sleeve so that the connecting rod drives the sliding rod to move the card joint and disengage the card joint from the card joint groove, and then separates the connecting head from the connecting pipe to complete the disassembly. During installation, the connecting pipe is inserted into the connecting head, the sliding sleeve is loosened, and the sliding sleeve is reset under the action of the second spring. The sliding rod drives the card joint to engage with the card joint groove under the action of the third spring, fixes it, and completes the installation, thereby achieving the purpose of facilitating the connection of the grouting pipe, reducing the workload, and improving the work efficiency.
