Description

Technical Field

[0001] This utility model relates to the technical field of health monitoring devices for truss structures, specifically a health monitoring device applicable to large-span truss structures. Background Technology

[0002] Truss: A structure consisting of members connected at both ends by hinges. Trusses are planar or spatial structures composed of straight members, generally with triangular units. Truss members mainly bear axial tension or compression, thus making full use of the material's strength. When the span is large, it can save material compared to solid beams, reduce self-weight, and increase stiffness. The advantages of trusses are that the members mainly bear tension or compression, which can make full use of the material, save material, and reduce structural weight. Commonly used types include steel trusses, reinforced concrete trusses, prestressed concrete trusses, timber trusses, steel and timber composite trusses, and steel and concrete composite trusses.

[0003] Currently available health monitoring devices for large-span truss structures are typically fixed with special adhesives during use, which makes them inconvenient to adjust and maintain. Therefore, there is an urgent need for health monitoring devices suitable for large-span truss structures to improve these issues. Utility Model Content

[0030] Reference Figure 4 and Figure 5 The connecting frame 12 has a fixing structure 15 inside, which includes an adapter hole 16. A fixing screw 17 is installed inside the adapter hole 16. An installation rod 18 is installed outside the fixing screw 17. A screw hole 19 is opened inside the installation rod 18. A support plate 20 is installed at the bottom of the installation rod 18.

[0031] Reference Figure 4 and Figure 5The bottom of the limiting frame 22 is provided with a monitor 23, the adapter hole 16 is opened inside the connecting frame 12, the fixing screw 17 is adapted to the screw hole 19, and the mounting rod 18 is fixedly connected to the support plate 20.

[0032] Reference Figure 4 and Figure 5 One end of the spring rod 21 is fixedly connected to the bottom of the support plate 20, and the other end of the spring rod 21 is fixedly connected to the limiting frame 22. In this embodiment, the spring rod 21 provides pressure to the limiting frame 22, and the limiting frame 22 is used to lock the monitor 23.

[0033] Working principle:

[0034] When it is necessary to install the monitor onto the surface of the truss body 1, the frame 3 needs to be placed on both sides of the truss body 1 first. After the frame 3 is placed on both sides of the truss body 1, the mounting bracket 4 will be snapped into the inside of the truss body 1. At the same time, the frame 3, the spring rod 5 and the connecting bracket 12 are all snapped into the outside of the truss body 1. Then, the frame 3 is pushed to slide on the outside of the truss body 1 until the frame 3 moves to the appropriate position, so that the through hole 13 is in a concentric state. The fixing bolt 14 is installed into the inside of the through hole 13 and the fixing bolt 14 is tightened with a tool. As the fixing bolt 14 is tightened, the two connecting brackets 12 will fit together. At the same time, the output shaft of the spring rod 5 will extend continuously, so that the frame 3 fits against the surface of the truss body 1.

[0035] After the frame 3 is installed, use a tool to connect to the outside of the locking block 9 and drive the locking block 9 to rotate inside the notch 6. Since the locking block 9 and the bidirectional threaded cylinder 8 are fixedly connected, the bidirectional threaded cylinder 8 will rotate inside the connecting hole 7 during the rotation of the locking block 9. The threaded connection between the bidirectional threaded cylinder 8 and the threaded rod 10 will push the support block 11 to move synchronously to both sides, guiding the support block 11 to fit into the truss body 1. At this point, the installation of the frame 3 is complete.

[0036] After completing the above steps, when installing the monitor, first place the monitor inside the connecting frame 12 and place the limiting frame 22 on top of the monitor 23. Since the limiting frame 22, spring rod 21, support plate 20 and mounting rod 18 are all fixedly connected, when the limiting frame 22 contacts the top of the monitor, the output shaft of spring rod 2 will be in an extended state. At this time, the operator needs to press down on the support plate 20. During the process of pressing down on the support plate 20, the output shaft of spring rod 21 will be compressed until the screw hole 19 and the adapter hole 16 are concentric. Pass the fixing screw 17 through the adapter hole 16 and into the screw hole 19. Then use a tool to rotate the fixing screw 17 and install the fixing screw 17 into the screw hole 19. The support plate 20 is fixed. After the support plate 20 is snapped into the inside of the connecting frame 12, spring rod 21 is in a compressed state, applying pressure to the limiting frame 22 so that the monitor 23 can always be in contact with the surface of the truss body 1.

[0037] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
