Description

Technical Field

[0001] This application relates to the technical field of construction tools, and in particular to a temporary tying device for cantilever structures. Background Technology

[0002] Temporary ties for cantilever structures are temporary safety and stabilization measures implemented during the construction phase to resist the overturning moment generated during concrete pouring and load application of the cantilever components. The core principle is to effectively transfer the load of the cantilever section to the completed main structure, which possesses sufficient strength and stability, through force-transferring components such as tie rods, wire ropes, or structural steel. This device typically has an adjustable function to precisely apply prestress, ensuring that the elevation, position, and overall stability of the cantilever structure meet design and specification requirements during construction. It is a crucial technical means to ensure safety during high-altitude operations and control structural deformation.

[0003] Currently, traditional temporary tie-up devices in cantilever structure construction have significant limitations: their structural design is often rigid, the length and angle adjustment range of the tie rods are extremely limited, making it impossible to flexibly adapt to the needs of different cantilever spans. They often require time-consuming and labor-intensive on-site cutting and welding, resulting in low construction efficiency and significant material waste. Furthermore, traditional devices are bulky, have limited connection methods, poor versatility, and are difficult to convert flexibly between different main structures such as concrete and steel structures. Their anchoring often relies on complex pre-embedded components, making installation and disassembly inconvenient, and resulting in low reuse rates, increasing construction costs and safety risks. Therefore, a new solution is urgently needed to overcome these shortcomings. Utility Model Content

Furthermore, the T-shaped screw component in the adjustment structure, in conjunction with the strip-shaped movable groove, provides fine-tuning and locking functions, ensuring precise fixation and stable load-bearing of the device's posture under complex working conditions.

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] See Figure 1-3 A temporary tie-up device for a cantilever structure includes a cantilever beam 1. A bottom fixing member 4 is provided on the lower outer surface of the cantilever beam 1. A tie rod 2 is fixedly connected to the upper outer surface of the bottom fixing member 4. A support structure 6 is movably connected to the rear outer surface of the bottom fixing member 4. An internal threaded connector 9 is fixedly connected to the upper inner surface of the support structure 6. A second fastener 7 is provided on the lower outer surface of the bottom fixing member 4. A threaded rod 8 is provided on the upper outer surface of the second fastener 7. The threaded rod 8 is threadedly connected to the internal threaded connector 9. A first fastener 5 is provided on the rear inner surface of the bottom fixing member 4.

[0018] The bottom fixing component 4 includes a vertical rod 401, and a horizontal bar 402 is rotatably connected to the upper outer surface of the vertical rod 401. The support structure 6 includes a limiting support rod 601, and a rotating shaft 602 and an adjusting structure 3 are fixedly connected to the front outer surface of the limiting support rod 601. The rotating shaft 602 is rotatably connected to the vertical rod 401.

[0019] Firstly, the flexible adjustment of the support angle is achieved through the movable connection between the support structure 6 and the bottom fixing member 4. Specifically, the pivot 602 at the front end of the support structure 6 can rotate within the upright 401 of the bottom fixing member 4, thereby changing the tilt angle of the entire support structure 6 to precisely adapt to different cantilever span requirements. At the same time, the T-shaped screw of the adjustment structure 3 can move within the strip-shaped movable groove of the limiting support rod 601 for preliminary lateral positioning. After the angle and lateral position are initially determined, tightening the limiting nut on the adjustment structure 3 locks the node in place, thus forming a stable triangular support core structure together with the cantilever beam 1, the tie rod 2, and the bottom fixing member 4, providing a solid foundation for subsequent prestressing.

[0020] The second fastener 7 includes a base 701, and a movable connector 702 is rotatably connected to the front outer surface of the base 701. The upper outer surface of the movable connector 702 is fixedly connected to the lower outer surface of the threaded rod 8.

[0021] The upper outer surface of the bottom fixing part 4 is provided with a first mounting hole that is compatible with the internal thread connector 9. The bottom fixing part 4 is fixedly connected to the internal thread connector 9 through the first mounting hole. The upper outer surface of the internal thread connector 9 is provided with an internal thread that is compatible with the threaded rod 8. The internal thread connector 9 is threadedly connected to the threaded rod 8 through the internal thread.

[0022] The adjusting structure 3 includes a T-shaped screw, the outer surface of the rear end of the T-shaped screw is fixedly connected to the outer surface of the front end of the limiting support rod 601, the outer wall of the T-shaped screw is threaded with a limiting nut, the outer surface of the rear end of the limiting nut is in contact with the outer surface of the front end of the limiting support rod 601, the outer surface of the front end of the limiting support rod 601 is provided with a strip-shaped movable groove adapted to the adjusting structure 3, the limiting support rod 601 is movably connected to the adjusting structure 3 through the strip-shaped movable groove, the outer surface of the front end of the upright rod 401 is provided with a first circular hole adapted to the rotating shaft 602, the upright rod 401 is rotatably connected to the rotating shaft 602 through the first circular hole.

[0023] After the stable triangular structure is formed, the tension force is applied and controlled through fine length adjustment. This function is mainly achieved by the threaded pair consisting of the threaded rod 8 and the internal threaded connector 9. By rotating the threaded rod 8, the movable connector 702 at its bottom can rotate on the base 701 of the second fastener 7 to avoid interference. The threaded rod 8 body generates precise axial extension and retraction. This movement pushes or pulls the support structure 6 connected to it, thereby subtly changing the effective support length of the entire triangular support system and applying a controllable lifting force or tension force to the cantilever beam 1. This design allows construction personnel to accurately adjust and lock the prestress state of the device according to the actual load, ensuring the stability and safety of the cantilever structure during construction. The entire process does not require on-site cutting or welding, making it efficient and reliable.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
