Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically a simple device for positioning prestressed tendons with adjustable angle. Background Technology

[0002] With the increasing demand for construction in my country and the continuous development of construction technology, many fields require the use of prestressed reinforced concrete precast components.

[0003] Because concrete has strong compressive strength but poor tensile strength, prestressed steel bars are usually added during fabrication to help the concrete resist tensile forces and improve its load-bearing capacity against self-weight and external loads. During concrete pouring, the prestressed tendons are impacted, causing them to deviate from their designed positions, resulting in a loss of effective prestress. Utility Model Content

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

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.

[0025] Please refer to Figures 1-3 A simple prestressing tendon positioning device with adjustable angle includes: a guide tube body 1, with a connecting ring 2 installed on the outer ring of the guide tube body 1, and multiple sets of connecting rings 2 are provided and hinged to each other; a telescopic mechanism, located outside the connecting rings 2 and used for adjusting the height of the guide tube body 1; and a fixing mechanism, located at the bottom of the telescopic mechanism and used for fixing prestressing tendons of different diameters, the fixing mechanism including a rotating component and a clamping component, the rotating component being located at the bottom of the telescopic mechanism and used to drive the position change of the clamping component, and the clamping component being located at the bottom of the telescopic mechanism and used to clamp and fix prestressing tendons of different diameters.

[0026] The telescopic mechanism includes a sliding rod 3 mounted on the outside of the connecting ring 2. A fixed rod 4 is mounted on the outer ring of the sliding rod 3. A groove 5 is formed on one side of the fixed rod 4. The sliding rod 3 slides in the inner cavity of the groove 5. A fastening assembly is installed in the inner cavity of the sliding rod 3 and the fixed rod 4. The fastening assembly includes threaded holes 6 formed in the inner cavity of the sliding rod 3 and the fixed rod 4. A threaded rod 7 is threadedly connected to the inner cavity of the threaded holes 6. Multiple sets of threaded holes 6 are formed and linearly distributed. A nut 8 is threadedly connected to the outer ring of the threaded rod 7.

[0027] In this embodiment of the present invention, in order to fix the position of the sliding rod 3, the threaded rod 7 in the fastening assembly is threadedly connected to the threaded hole 6 in the inner cavity of the sliding rod 3 and the fixed rod 4, and the nut 8 is used to further lock the threaded rod 7 to ensure the stability and reliability of the telescopic mechanism.

[0028] Please refer to Figures 1-4The rotating assembly includes a fixing ring 9 mounted at the bottom of the fixing rod 4. A fixing hole 10 is formed in the inner cavity of the fixing ring 9, and a rotating screw 11 is threaded into the inner cavity of the fixing hole 10. A knob 12 is mounted on one side of the rotating screw 11. The clamping assembly includes a clamping block 13 mounted on the other side of the rotating screw 11. The rotating screw 11 and the clamping block 13 are connected by a bearing. A limit assembly is installed between the clamping block 13 and the fixing ring 9. The limit assembly includes a telescopic rod 14 installed between the fixing ring 9 and the clamping block 13. Multiple sets of telescopic rods 14 are arranged in a rectangular array.

[0029] A limiting hole 15 is provided in the inner cavity of the connecting ring 2. A limiting screw 16 is threadedly connected to the inner cavity of the limiting hole 15. A limiting block 17 is threadedly connected to the outer ring of the limiting screw 16.

[0030] In this embodiment of the invention, the setting of the limiting hole 15, the limiting screw 16, and the limiting block 17 in the inner cavity of the connecting ring 2 further enhances the stability and safety of the device. By threading the limiting screw 16 and the limiting block 17, the rotation angle of the connecting ring 2 can be limited, thereby ensuring the stability of the device at a specific angle.

[0031] In use, the guide tube body 1 serves as the main structure of the device, and is flexibly hinged by multiple sets of connecting rings 2 installed on the outer ring. These connecting rings 2 ensure the stability and adaptability of the device at different angles. On the outside of the guide tube body 1, the telescopic mechanism plays an important role in adjusting the height of the guide tube body 1. Specifically, the sliding rod 3 slides within the groove 5 of the fixed rod 4. By adjusting the position of the sliding rod 3, the height of the guide tube body 1 can be changed. To fix the position of the sliding rod 3, the threaded rod 7 in the fastening assembly is threadedly connected to the threaded hole 6 in the inner cavity of the sliding rod 3 and the fixed rod 4. The nut 8 is used to further tighten the threaded rod 7, ensuring the stability and reliability of the telescopic mechanism.

[0032] At the bottom of the telescopic mechanism, a fixing mechanism is used to fix prestressing tendons of different diameters. The rotating assembly allows for flexible changes in the position of the clamping assembly through the fixing ring 9 at the bottom of the fixing rod 4 and the rotating screw 11 in the fixing hole 10. The user can rotate the rotating screw 11 by rotating the knob 12, thereby adjusting the position of the clamping assembly. The clamping block 13 in the clamping assembly is connected to the rotating screw 11 through a bearing, ensuring the stability and flexibility of the clamping block 13 during rotation. At the same time, the limiting assembly between the clamping block 13 and the fixing ring 9, namely multiple sets of telescopic rods 14 arranged in a rectangular array, provides additional support and limiting function for the clamping block 13, preventing displacement of the clamping block 13 when clamping the prestressing tendons.

[0033] Furthermore, the inclusion of a limiting hole 15, a limiting screw 16, and a limiting block 17 within the inner cavity of the connecting ring 2 further enhances the stability and safety of the device. By threadedly connecting the limiting screw 16 and the limiting block 17, the rotation angle of the connecting ring 2 can be limited, thereby ensuring the stability of the device at specific angles. This design not only improves the flexibility of the device's use but also enhances its reliability and safety in practical applications.
