Description

Technical Field

[0001] This utility model relates to the field of anchor technology, and in particular to a carbon fiber prestressed anchor. Background Technology

[0002] Carbon fiber prestressed anchors are devices used in post-tensioned structures or components. Made of carbon fiber, they reinforce concrete structures by providing pre-stress and are widely used in various concrete structures such as buildings, bridges, transmission towers, and hydraulic engineering projects. Their main function is to maintain the tension of the prestressing tendons and transfer it to the interior of the concrete, optimizing and controlling the stress within the concrete structure.

[0003] Existing carbon fiber prestressed anchors are mostly integrated units. During use, installation is completed by connecting the clips at both ends of the carbon fiber cloth to the base. However, in this process, the length of the carbon fiber cloth is fixed and cannot be cut, which means that it can only reinforce concrete devices of a fixed length, thus reducing the practicality of the device. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a carbon fiber prestressed anchor.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a carbon fiber cloth prestressed anchor, comprising a carbon fiber cloth body, clamps respectively provided at both ends of the carbon fiber cloth body, screws respectively installed at one end of the two clamps, a support seat installed on each of the two screws, a fixing hole through the support seat, the screws passing through the fixing hole, and a fixing nut threadedly connected to the outer wall of each of the two screws, the side wall of each fixing nut abutting against the side wall of each of the two support seats respectively.

[0006] By adopting the above technical solution, when workers need to use carbon fiber prestressed anchors, they must first fix the support base to the concrete structure. Then, they must fix the clamps to both ends of the carbon fiber fabric body. Next, they pass bolts through the fixing holes in the support base. At this point, they install the fixing nuts onto the screws, ensuring the sidewalls of the fixing nuts abut against the sidewalls of the support base. Then, they can adjust the tension of the carbon fiber fabric body by moving the screws. During this process, the carbon fiber fabric body can be freely cut to different lengths by fixing it to the clamps, thus improving the practicality of the device.

[0007] Furthermore, the clamp includes two clamping plates, a clamping cylinder sleeved on the outer wall of the two clamping plates, and a connector installed on the side wall of the clamping cylinder. The connector is connected to the screw. The inner and outer diameters of the clamping plates gradually decrease from the end near the support to the end away from the support. The inner diameter of the clamping cylinder gradually decreases from the end near the support to the end away from the support.

[0008] By adopting the above technical solution, when workers need to fix the clamps to both ends of the carbon fiber cloth body, they clamp the two clamping plates to both ends of the carbon fiber cloth body. At this time, the workers place the clamping sleeve on the outer wall of the clamping plates. Subsequently, the workers install the connectors onto the side wall of the clamping sleeve. During this process, the inner and outer diameters of the clamping plates gradually decrease from the end closer to the support to the end farther from the support, and the inner diameter of the clamping sleeve also gradually decreases from the end closer to the support to the end farther from the support, thus firmly fixing the clamps to both ends of the carbon fiber cloth body. This reduces the difficulty for workers to install the clamps at both ends of the carbon fiber cloth body, thereby reducing the workload of the workers.

[0009] Furthermore, the inner diameter of the clamping cylinder near the support is smaller than the outer diameter of the clamping piece near the support.

[0010] By adopting the above technical solution, the inner diameter of the clamping cylinder near the support is smaller than the outer diameter of the clamping piece near the support, which reduces the probability of the clamping cylinder and the clamping piece separating from each other, thereby improving the stability of the device.

[0011] Furthermore, the outer wall of the clamp near the support is provided with an external thread, and the inner wall of the connector away from the support is provided with an internal thread, and the external thread and the internal thread are threadedly connected.

[0012] By adopting the above technical solution, when the worker needs to install the connector onto the side wall of the clamp, the worker screws the connector onto the outer wall of the clamp. In this process, the connection is made through the external thread and the internal thread, which reduces the difficulty for the worker to connect the connector to the clamp and thus reduces the difficulty of the worker's work.

[0013] Furthermore, the connector has a threaded hole on its side wall away from the clamp, and the screw is threadedly connected to the threaded hole.

[0014] By adopting the above technical solution, the threaded hole reduces the difficulty for workers to install the screw onto the side wall of the connector, thereby reducing the difficulty of the workers' work.

[0015] Furthermore, a support plate is fixedly installed on the side wall of the support base, and a fixing groove is provided through the side wall of the support plate. Multiple fixing grooves are arranged in an array on the side wall of the support plate.

[0016] By adopting the above technical solution, the support plate and fixing groove reduce the difficulty for workers to install the support base onto the concrete building, thereby reducing the difficulty of the workers' work.

[0017] Furthermore, a protective sleeve is fitted on the outer wall of one of the screws, and the side wall of the fixing nut abuts against the side wall of the protective sleeve.

[0018] By adopting the above technical solution, the protective sleeve protects the screw, thereby reducing the probability of screw damage and extending the service life of the device.

[0019] Furthermore, the support plate is made of composite steel, the support base is made of composite steel, the clamp is made of composite steel, and the protective sleeve is made of composite steel.

[0020] By adopting the above technical solutions, the support plate, support base, clamp, and protective sleeve made of composite steel material improve the overall strength of the device.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. In this application, when workers need to use carbon fiber prestressed anchors, they must first fix the support base to the concrete structure. Then, they must fix the clamps to both ends of the carbon fiber fabric body. Next, they pass bolts through the fixing holes on the support base. Then, they install the fixing nuts onto the screw rods, ensuring the sidewalls of the fixing nuts abut against the sidewalls of the support base. Subsequently, the tension of the carbon fiber fabric body can be adjusted by moving the screw rods. During this process, the carbon fiber fabric body can be freely cut by fixing it to both ends with clamps, allowing it to be used to reinforce concrete structures of different lengths, thus improving the practicality of the device.

[0023] 2. In this application, when workers need to fix the clamps to both ends of the carbon fiber cloth body, they clamp two clamping plates to both ends of the carbon fiber cloth body. At this time, workers place the clamp sleeve on the outer wall of the clamping plates. Subsequently, workers install the connectors onto the side wall of the clamp sleeve. During this process, the inner and outer diameters of the clamping plates gradually decrease from the end closer to the support to the end farther from the support, and the inner diameter of the clamp sleeve gradually decreases from the end closer to the support to the end farther from the support, so that the clamps are firmly fixed to both ends of the carbon fiber cloth body, thereby reducing the difficulty for workers to install the clamps at both ends of the carbon fiber cloth body, and thus reducing the difficulty of the workers' work.

[0024] 3. In this application, the inner diameter of the clamping cylinder near the support is smaller than the outer diameter of the clamping plate near the support, which reduces the probability of the clamping cylinder and the clamping plate separating from each other, thereby improving the stability of the device.

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] like Figure 1-5 As shown in the illustration, this application discloses a carbon fiber prestressed anchor, including a carbon fiber fabric body 1, clamps 2, screws 3, fixing nuts 31, and support seats 4. Two clamps 2 are provided and located at both ends of the carbon fiber fabric body 1. The screws 3 are installed at one end of each clamp 2, with their axes horizontal. Two support seats 4 are provided and installed on the two screws 3. Fixing holes 41 are formed through the support seats 4, and the screws 3 pass through the fixing holes 41. Two fixing nuts 31 are provided and threadedly connected to the outer walls of the two screws 3, respectively. The side walls of the two fixing nuts 31 abut against the side walls of the two support seats 4.

[0033] When using carbon fiber prestressed anchors, workers must first fix the support base 4 to the concrete structure. Then, they must fix the clamps 2 to both ends of the carbon fiber fabric body 1. Next, bolts are passed through the fixing holes 41 on the support base 4. At this point, the fixing nuts 31 are installed onto the screws 3, so that the sidewalls of the fixing nuts 31 abut against the sidewalls of the support base 4. Then, the tension of the carbon fiber fabric body 1 can be adjusted by moving the screws 3. During this process, the carbon fiber fabric body 1 can be freely cut by fixing it to both ends with the clamps 2, allowing it to be used to reinforce concrete structures of different lengths, thus improving the practicality of the device.

[0034] The fixture 2 comprises clamping plates 21, clamping cylinders 22, and connecting members 23. Two clamping plates 21 are provided and mounted on the carbon fiber cloth body 1. Two clamping cylinders 22 are provided and fitted onto the outer walls of the two clamping plates 21. The connecting members 23 are mounted on the side walls of the clamping cylinders 22 and are connected to the screw 3. The inner and outer diameters of the clamping plates 21 gradually decrease from the end closer to the support base 4 to the end farther from the support base 4, and the inner diameter of the clamping cylinders 22 also gradually decreases from the end closer to the support base 4 to the end farther from the support base 4.

[0035] When workers need to fix clamp 2 to both ends of the carbon fiber cloth body 1, they clamp two clamping pieces 21 to both ends of the carbon fiber cloth body 1. At this time, workers put clamping cylinder 22 on the outer wall of clamping piece 21. Subsequently, workers install connector 23 onto the side wall of clamping cylinder 22. During this process, the inner and outer diameters of clamping piece 21 gradually decrease from the end closer to support base 4 to the end farther from support base 4, and the inner diameter of clamping cylinder 22 gradually decreases from the end closer to support base 4 to the end farther from support base 4, so that clamp 2 is firmly fixed to both ends of the carbon fiber cloth body 1, thereby reducing the difficulty for workers to install clamp 2 at both ends of the carbon fiber cloth body 1, and thus reducing the difficulty of workers' work.

[0036] To improve the stability of the device, the inner diameter of the clamp 22 near the support 4 is smaller than the outer diameter of the clamp 21 near the support 4. This smaller inner diameter of the clamp 22 near the support 4 reduces the probability of the clamp 22 and clamp 21 separating from each other, thereby improving the stability of the device.

[0037] To reduce the difficulty of the workers' work, the outer wall of the clamp 22 near the support 4 is provided with an external thread 5, and the inner wall of the connector 23 away from the support 4 is provided with an internal thread 51. The external thread 5 and the internal thread 51 are threadedly connected. When the workers need to install the connector 23 onto the side wall of the clamp 22, they screw the connector 23 onto the outer wall of the clamp 22. During this process, the connection is made through the threaded connection of the external thread 5 and the internal thread 51, thereby reducing the difficulty for the workers to connect the connector 23 and the clamp 22, and thus reducing the difficulty of the workers' work.

[0038] To reduce the difficulty of the work for the workers, a threaded hole 6 is provided on the side wall of the connector 23 away from the clamp 22, and the screw 3 is threadedly connected to the threaded hole 6. The threaded hole 6 reduces the difficulty for the workers to install the screw 3 onto the side wall of the connector 23, thereby reducing the difficulty of the work for the workers.

[0039] To reduce the difficulty of the work for the workers, a support plate 7 is fixedly installed on the side wall of the support base 4. A fixing groove 71 is formed through the side wall of the support plate 7, and multiple fixing grooves 71 are arranged in a parallel array on the side wall of the support plate 7. The support plate 7 and the fixing grooves 71 reduce the difficulty for the workers to install the support base 4 onto the concrete structure, thereby reducing the difficulty of the workers' work.

[0040] To extend the service life of the device, a protective sleeve 8 is fitted onto the outer wall of one of the screws 3, and the side wall of the fixing nut 31 abuts against the side wall of the protective sleeve 8. The protective sleeve 8 protects the screw 3, thereby reducing the probability of damage to the screw 3 and extending the service life of the device.

[0041] To improve the overall strength of the device, the support plate 7, the support base 4, the clamp 2, and the protective sleeve 8 are all made of composite steel. The composite steel support plate 7, support base 4, clamp 2, and protective sleeve 8 enhance the overall strength of the device.

[0042] The operating principle of a carbon fiber prestressed anchor in this embodiment is as follows: When workers need to use the carbon fiber prestressed anchor, they need to fix the support base 4 to the concrete structure. Then, the workers need to fix the clamps 2 to both ends of the carbon fiber body 1. Next, the workers pass bolts through the fixing holes 41 opened on the support base 4. At this time, the workers install the fixing nuts 31 onto the screws 3 so that the side wall of the fixing nuts 31 abuts against the side wall of the support base 4. Then, the workers can adjust the tension of the carbon fiber body 1 by moving the screws 3. During this process, by fixing the carbon fiber body 1 to both ends with the clamps 2, the carbon fiber body 1 can be cut at will, allowing it to reinforce concrete structures of different lengths, thereby improving the practicality of the device.

[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
