Description

Technical Field

[0001] This application relates to the field of tensioned beam technology, and in particular to a vibration-damping cable-stayed tensioned beam structure and an early warning device. Background Technology

[0002] Tensioned beam structures are a novel hybrid roof system distinct from traditional structures. They are a hybrid structural system composed of a rigid upper chord, flexible cables, and intermediate struts, forming a novel self-balancing system. This is a large-span prestressed spatial structure system and a successful innovation in the development of hybrid structural systems. Tensioned beam structures are simple, have clearly defined stress distribution, offer diverse structural forms, fully utilize the advantages of both rigid and flexible materials, and are easy to manufacture, transport, and construct, thus possessing excellent application prospects. In the field of building structures, with continuous technological advancements, the requirements for structural safety, stability, and durability are increasingly stringent. Especially in large-span, heavy-load, and complex environments, effectively reducing vibration and improving structural stability and safety has become a pressing technical challenge.

[0003] The existing technology still has the following problems: 1. Traditional tensioned beams lack early warning devices. Due to the large vibration amplitude under wind and vibration loads, the lower chord cables are prone to loosening, affecting the overall structural performance and fatigue failure. There is no warning when the structure fails, resulting in serious loss of life and property. In addition, under long-term use, wind causes the cables to sway significantly, increasing the wear of the cables and tensioned beams and shortening the service life of the tensioned beams.

[0004] 2. Existing tensioned beam structures rely on their own tension to achieve wind resistance, but when the external wind force is strong, tilting and deformation will still occur. This makes tensioned beams risky to use and cannot guarantee the personal safety of users. Some of them are supported by auxiliary supports, but after the position of the support rod is fixed, it is difficult to connect it with the cable, thus affecting the strength of the auxiliary support for the cable.

[0014] The technical solution provided in this application has at least the following technical effects or advantages: 1. By employing an early warning component, this invention effectively solves the problem of traditional tensioned beams lacking early warning devices. Due to the large vibration amplitude under wind and vibration loads, the lower chord cables are prone to slack, affecting the overall structural performance and causing fatigue damage. The lack of early warning when structural damage occurs leads to serious loss of life and property. Furthermore, over long periods of use, wind causes significant swaying of the cables, increasing wear on both the cables and the tensioned beam, shortening its service life. This invention, through its early warning component, reduces the swaying of the cables under wind loads, lowers wear between the cables and the tensioned beam, and improves its service life. Simultaneously, when the lower chord cables slack and tilt, it provides timely warnings to prevent loss of life and property.

[0015] 2. By adopting a support component, the problem of existing tensioned beam structures relying on their own tension to achieve wind resistance is effectively solved. However, when the external wind force is strong, tilting and deformation still occur, which makes the tensioned beam risky during use and cannot guarantee the personal safety of the users. Partial support is provided by the support rods, but after the position of the support rods is fixed, it is difficult to connect them with the cables, thus affecting the strength of the auxiliary support for the cables. This invention can provide auxiliary support for the cables through the support component, and the length of the support component can be adjusted after installation, so that the support component can provide auxiliary support for the cables and maintain the original prestress of the cables.

Detailed Implementation

[0018] In the absence of early warning for cable tilting, this invention provides timely warnings through an early warning component to prevent loss of life and property. Furthermore, even when there is strong wind, tilting and deformation may still occur, and this invention provides auxiliary support for the cable through a support component.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3As shown, a vibration-damping cable-stayed beam structure includes an upper chord 1. Connecting blocks 2 are fixedly installed at both ends of the upper chord 1. A hydraulic cylinder 3 is fixedly installed inside the connecting block 2. A piston rod is provided inside the hydraulic cylinder 3, and the piston rod is fixedly connected to a connecting head 4. A connecting disc 5 is rotatably connected to the inner cavity of the connecting head 4. A U-shaped connecting rod 6 is sleeved on the outer surface of the connecting disc 5. A jack 7 is fixedly installed on the outer surface of the U-shaped connecting rod 6. A cable 10 is fixedly connected to the end of the jack 7 away from the U-shaped connecting rod 6. Warning components 8 are provided at both ends of the upper chord 1. A support component 9 is sleeved on the outer surface of the cable 10. A support frame 11 is fixedly installed at the bottom end of the upper chord 1. The support component 9 and the bottom end of the support frame 11 are fixedly connected. The connecting head 4 is pulled by the hydraulic cylinder 3. The U-shaped connecting rod 6 rotates within the inner cavity of the connecting plate 5, causing the position of the jack 7 to change. The hydraulic cylinder 3, in conjunction with the jack 7, can tension the cable 10 to achieve the prestressed state required by the design, significantly improving the load-bearing capacity and stiffness of the structure. The early warning component 8 is used to provide early warning of the inclination of the cable 10, issuing an alarm in a timely manner when the inclination of the cable 10 changes. It can also correct both ends of the cable 10, reducing the swaying amplitude of the cable 10 under wind force. The support component 9 is used for auxiliary support of the cable 10, and together with the early warning component 8, it reduces the swaying amplitude of the cable 10 under wind force, reduces wear between the cable 10 and the support frame 11 and other components, and improves the service life of the equipment.

[0021] Please see Figure 4 , Figure 5 and Figure 6As shown, the support assembly 9 includes a fixed plate 91, with fixed holes 92 at both ends. A rotating rod 93 is rotatably connected to the bottom end of the fixed plate 91, and an adjusting rod 94 is fixedly connected to the bottom end of the rotating rod 93. A limiting plate 95 is fixedly installed at the bottom end of the rotating rod 93, and a telescopic rod 96 is sleeved on the bottom end of the adjusting rod 94. A second limiting rod 97 is fixedly installed on the upper surface of the telescopic rod 96, and a storage cavity 98 is formed at the bottom end of the second limiting rod 97. A spring rod 99 is slidably connected to the inner cavity of the storage cavity 98, and a fourth spring 99 is sleeved on the outer surface of the spring rod 99. 10. A support ring 911 is fixedly installed at the bottom end of the elastic rod 99. The two ends of the cable 10 are fixedly connected to the jack 7. The support ring 911 and the cable 10 are sleeved together. The bottom end of the warning component 8 is sleeved together with the cable 10. The second limit rod 97 and the limit plate 95 are slidably connected. The adjusting rod 94 and the telescopic rod 96 are connected by threads. The support component 9 is fixedly installed to the support frame 11 by bolts passing through the fixing hole 92. Except for the fixing plate 91, the rest of the components can move up and down in the inner cavity of the support frame 11. The fourth spring 910 is located between the inner wall of the second limit rod 97 and the elastic rod 99. The fixing plate 91 is fixed to the upper chord 1 by bolts. The cable 10 passes through the inner cavity of the support ring 911. By adjusting the position of the adjusting rod 94 in the inner cavity of the telescopic rod 96, the cable 10 maintains prestress when deployed. Rotating the rotating rod 93 drives the adjusting rod 94 to rotate, and the rotation of the adjusting rod 94 causes the telescopic rod 96 to move on the adjusting rod 94. At this time, the second limiting rod 97 moves on the limiting plate 95. The second limiting rod 97 is used to limit the telescopic rod 96 to prevent it from rotating. Thus, the position of the telescopic rod 96 changes under the rotation of the adjusting rod 94. The lifting mechanism causes the spring rod 99 to move up and down. The movement of the spring rod 99 causes the support ring 911 to move, adjusting the support ring 911 to a suitable position. This ensures that even after the support assembly 9 is installed, the support ring 911 can still provide auxiliary support for the cable 10. Furthermore, the elasticity of the fourth spring 910 allows the spring rod 99 to move within the cavity of the storage chamber 98. When the cable 10 is blown by the wind, the support ring 911 has a certain degree of flexibility, preventing the support ring 911 from being too rigid and increasing the wear on the cable 10 and the support ring 911, thus reducing the swaying amplitude of the cable 10 under wind force.

[0022] Example 2: Please refer to Figure 7As shown, the warning device includes a warning component 8, which includes a connecting frame 81. A buffer rod 82 is fixedly installed at the middle of the top of the connecting frame 81. A first spring 83 is sleeved on the top of the buffer rod 82. First limiting rods 84 are fixedly installed at both ends of the upper surface of the connecting frame 81. A pressure block 85 is fixedly installed on the lower surface of the connecting frame 81. A correction mechanism 86 is provided below the connecting frame 81. A warning mechanism 87 is provided on one side of the connecting frame 81. The first spring 83 is located between the buffer rod 82 and the upper chord 1. The first limiting rod 84 and the upper chord 1 are slidably connected. The buffer rod 82 and the upper chord 1 are also slidably connected. The top of 87 is fixedly connected to the upper chord 1. When the cable 10 vibrates under wind, the elastic force of the first spring 83 reduces the swaying amplitude of the buffer rod 82 in the inner cavity of the upper chord 1, and the sliding of the first limiting rod 84 in the inner cavity of the upper chord 1 keeps the position of the connecting frame 81 stable. The correction mechanism 86 in the inner cavity of the connecting frame 81 always tends to the middle position, reducing the vibration amplitude of the cable 10 under wind, thereby reducing the wear between equipment under wind. After long-term use, the prestress of the cable 10 changes, causing the cable 10 to tilt. At this time, the cable 10 drives the correction mechanism 86 to move downward, thereby driving the warning mechanism 87 to issue an alarm.

[0023] Please see Figure 7 and Figure 8As shown, the correction mechanism 86 includes a correction frame 861, with correction rods 862 fixedly installed at both ends of the correction frame 861. A second spring 863 is sleeved on the outer surface of the correction rod 862. A threaded rod 864 is rotatably connected to the inner cavity of the correction frame 861. A sliding groove 865 is provided at the bottom end of the correction frame 861. A clamping arm 866 is sleeved on the outer surface of the threaded rod 864. The clamping arm 866 and the threaded rod 864 are connected by threads, and the clamping arm 866 and the sliding groove 865 are slidably connected. The threads at both ends of the 864 are in opposite directions, and there are two clamping arms 866 on one threaded rod 864. The bottom end of the clamping arm 866 is fixedly connected to a first straightening ring 867, and the bottom end of the clamping arm 866 is fixedly connected to a second straightening ring 868. The second spring 863 is located between the inner wall of the connecting frame 81 and the straightening frame 861. The straightening rod 862 and the connecting frame 81 are slidably connected. The outer sides of the upper and lower ends of the first straightening ring 867 are hollowed out, and the middle parts of the upper and lower ends of the second straightening ring 868 are hollowed out. The first straightening ring 867 and the second straightening ring 868 engage, and the first straightening ring 867 and the second straightening ring 868 are sleeved on the cable 10. By rotating the threaded rod 864, the clamping arm 866 moves on the slide groove 865, thereby moving the first straightening ring 867 and the second straightening ring 868. This allows the first straightening ring 867 and the second straightening ring 868 to accommodate cables 10 of different diameters, improving the fault tolerance of the equipment. This enables it to be used for early warning of cables 10 of different thicknesses. When the cable 10 sways, it causes the clamping arm 866 to sway. The swaying of the clamping arm 866 causes the straightening frame 861 to sway. The swaying of the straightening frame 861 causes the straightening rod 862 to move in the inner cavity of the connecting frame 81. At this time, the elastic force of the second spring 863 reduces the swaying amplitude of the straightening frame 861 under vibration load and quickly returns it to its original position, thereby reducing the vibration amplitude of the cable 10 under wind force, reducing the wear of the cable 10 during use, and improving the service life of the equipment.

[0024] Please see Figure 7 , Figure 8 and Figure 9As shown, the warning mechanism 87 includes a warning block 871. A button 872 is provided on the upper surface of the warning block 871. An alarm 873 is fixedly installed at the bottom end of the warning block 871. A slide rod 874 is provided inside the warning block 871. The warning block 871 and the slide rod 874 are slidably connected. An insertion hole 875 is opened on the outer surface of the slide rod 874. A fixing bracket 876 is fixedly installed on the outer surface of the warning block 871. An insertion rod 877 is inserted into the inner cavity of the fixing bracket 876. The insertion rod 877 and the insertion hole 875 are engaged. A fixing ring 878 is fixedly installed on the outer surface of the insertion rod 877. A third spring 879 is sleeved on the outer surface of the insertion rod 877. The three springs 879 are located between the fixed ring 878 and the fixed frame 876. The top of the slide rod 874 is fixedly connected to the upper chord 1. The button 872 and the alarm 873 are electrically connected. The pressure block 85 and the button 872 are aligned, and the button 872 is located directly below the pressure block 85. Pressing the button 872 controls the alarm 873 to sound an alarm. When the prestress of the cable 10 changes during use, causing the cable 10 to tilt more, the positions of the first correction ring 867 and the second correction ring 868 where the cable 10 is located become lower. That is, the cable 10 exerts a downward pulling force on the connecting frame 81. At this time, the connecting frame 81 drives the first spring 83 to contract. The buffer rod 82 descends, causing the pressure block 85 on the connecting frame 81 to descend as well. This brings the pressure block 85 into contact with the button 872, squeezing the button 872 on the warning block 871. This triggers the alarm 873, alerting staff to perform maintenance. Simultaneously, the position of the button 872 can be controlled so that the alarm is triggered when the cable 10 tilts to a certain degree. In other words, the alarm can be triggered promptly when the cable 10 tilts and causes the connecting frame 81 to descend to a set position. Pulling the insertion rod 877 compresses the third spring 879, disengaging the insertion rod 877 from the insertion hole 875 and moving the warning block 871 on the slide rod 874. When the cable is in the correct position, release the insertion rod 877. At this time, the elastic force of the third spring 879 drives the fixing ring 878 to move towards the insertion hole 875, so that the insertion rod 877 on the fixing frame 876 and the insertion hole 875 on the slide rod 874 are engaged, and the warning block 871 is fixed on the slide rod 874 again. At this time, the distance between the button 872 and the pressure block 85 changes, thereby controlling the cable 10 to press down on the connecting frame 81 at different inclinations. The position of the warning block 871 can be controlled to provide timely warning when the cable 10 tilts, avoiding the difficulty in observing the changes in the prestress of the cable 10 at high altitudes, which may cause the cable 10 to tilt and make timely maintenance impossible.

[0025] In summary, by pulling the connector head 4 with the hydraulic cylinder 3, the U-shaped connecting rod 6 rotates within the cavity of the connecting plate 5, causing the U-shaped connecting rod 6 to change the position of the jack 7. The hydraulic cylinder 3, in conjunction with the jack 7, can tension the cable 10 to achieve the designed prestressed state, significantly improving the structure's load-bearing capacity and stiffness. The early warning component 8 is used to provide early warning of the cable 10's tilt, issuing an alarm promptly when the cable 10's tilt changes. Simultaneously, it can correct both ends of the cable 10, mitigating the impact of changes in tilt. The swaying amplitude of the cable 10 under wind force is reduced by the support component 9, which provides auxiliary support for the cable 10. Simultaneously, it works with the warning component 8 to reduce the swaying amplitude of the cable 10 under wind force, thereby reducing wear between the cable 10 and components such as the support frame 11 and improving the service life of the equipment. The fixing plate 91 is fixed to the upper chord 1 by bolts. The cable 10 passes through the inner cavity of the support ring 911. By adjusting the position of the adjusting rod 94 within the inner cavity of the telescopic rod 96, the cable 10 maintains prestress during deployment. Rotating the rotating rod 93 drives the support ring 91. 1. Move the support ring 911 to a suitable position so that even after the support assembly 9 is installed, the support ring 911 can still provide auxiliary support for the cable 10. The elastic force of the fourth spring 910 allows the spring rod 99 to move within the housing cavity 98. When the cable 10 is blown by the wind, the support ring 911 has a certain degree of flexibility to prevent excessive rigidity and increased wear on the cable 10 and support ring 911, reducing the swaying amplitude of the cable 10 under wind force. When the cable 10 vibrates under wind force, the first spring... The elasticity of 83 reduces the swaying amplitude of the buffer rod 82 in the inner cavity of the upper chord 1, and the sliding of the first limiting rod 84 in the inner cavity of the upper chord 1 keeps the position of the connecting frame 81 stable. The correction mechanism 86 in the inner cavity of the connecting frame 81 always tends to the middle position, reducing the vibration amplitude of the wind-driven cable 10, thereby reducing the wear between equipment under wind. After long-term use, the prestress of the cable 10 changes, causing the cable 10 to tilt. At this time, the cable 10 drives the correction mechanism 86 to move downward, thereby driving the warning mechanism 87 to issue an alarm.
