Description

Technical Field

[0001] This utility model relates to the field of alarm device technology, and in particular to a deformation alarm device for tall formwork support. Background Technology

[0002] High formwork refers to formwork operations with a height of 8 meters or more. It is a high-risk sub-project exceeding a certain scale and requires expert review. During concrete pouring, high formwork is subjected to construction loads and concrete loads, which can easily cause deformation of the support frame, leading to collapse, overturning, and other safety accidents. Therefore, deformation monitoring of the high formwork frame is particularly important during its construction.

[0003] Currently, in the construction process of concrete pouring using high formwork, construction workers usually use tools to periodically inspect the high formwork. Due to the height of the formwork, construction workers need to climb to a high place to use tools to accurately inspect key support points, which is very inconvenient and somewhat dangerous.

[0024] In this embodiment, a movable plate 7 is movably installed at the top of the fixed box 2. The telescopic cover 4 penetrates the fixed box 2 and is fixedly connected to the movable plate 7. A first spring 11 is fixedly installed between the movable plate 7 and the weight sensor 10. A threaded groove 19 is opened on the side wall of the fixed box 2 corresponding to the position of the movable plate 7. A threaded nail 20 is movably installed in the threaded groove 19. A slot 18 is opened on the side wall of the movable plate 7 corresponding to the position of the threaded groove 19. The top of the threaded nail 20 can be engaged in the slot 18. By rotating the threaded nail 20, the top of the threaded nail 20 is moved out of the slot 18. When the bracket 1 deforms, the distance between the structures will change. At this time, the movable rod 5 on the device will drive the telescopic cover 4 to move into the fixed box 2. The movable plate 7 on the telescopic cover 4 will squeeze the first spring 11. Since the first spring 11 is in contact with the weight sensor 10, the weight sensor 10 will transmit information to the controller 8.

[0025] In this embodiment, a connecting cover 14 is fixedly installed on the side wall of the telescopic cover 4. A limiting rod 15 is movably installed in the connecting cover 14. The top end of the limiting rod 15 extends through the telescopic cover 4 to the outside of the movable rod 5. Limiting grooves 13 are evenly spaced on the movable rod 5 at the positions corresponding to the limiting rod 15. The top end of the limiting rod 15 can be engaged in the limiting groove 13. A stop block 16 is provided in the connecting cover 14. The stop block 16 is fixedly installed on the side wall of the limiting rod 15. A second spring 17 is movably installed between the stop block 16 and the inner wall of the connecting cover 14. By pulling the limiting rod 15 outward, the top end of the limiting rod 15 is pulled out of the limiting groove 13. At this time, the movable rod 5 can be pulled out of the telescopic cover 4. When the appropriate length is adjusted, the limiting rod 15 is released. The second spring 17 will automatically reset the limiting rod 15, so that the top end of the limiting rod 15 is engaged back in the limiting groove 13, fixing the movable rod 5, thereby completing the length adjustment of the device.

[0026] In this embodiment, a movable groove 22 is provided on the fixed block 21, and the threaded rod 23 is movably installed in the movable groove 22. The threads at both ends of the threaded rod 23 are opposite, and clamping blocks 24 are movably installed at both ends of the threaded rod 23. The clamping blocks 24 are threadedly connected to the threaded rod 23. One end of the threaded rod 23 penetrates the top of the fixed block 21 and is fixedly installed with a control ring 26. Rotating the threaded rod 23 can control the clamping blocks 24 to clamp the bracket 1.

[0027] In this embodiment, a display 9 is fixedly installed on the side wall of the fixed box 2. The display 9 is connected to the weight sensor 10. The weight sensor 10 can display the weight value it receives on the display 9. The larger the value on the display 9, the greater the deformation.

[0028] In this embodiment, a connecting frame 25 is fixedly installed at the bottom of the fixed block 21, and the bottom end of the connecting rod 3 and the top end of the movable rod 5 are movably connected to the connecting frame 25.

[0029] In this embodiment, an alarm 12 is fixedly installed on the outside of the fixed box 2. The controller 8 can control the alarm 12. The weight sensor 10 transmits information to the controller 8. When the value exceeds the preset value in the controller 8, the controller 8 will control the alarm 12 to sound an alarm to remind the surrounding people.

[0030] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, the device is moved to the key support point of the bracket 1, and then the clamping structure 6 on the connecting rod 3 and the movable rod 5 is opened and clamped onto the bracket 1, fixing the device on the bracket 1. At this time, neither end of the connecting rod 3 nor the movable rod 5 is under force. Then, the threaded nail 20 is rotated, and the top of the threaded nail 20 is moved out of the slot 18. When the bracket 1 deforms, the distance between the structures will change. At this time, the movable rod 5 on the device will drive the telescopic cover 4 to move into the fixed box 2. The movable plate 7 on the telescopic cover 4 will squeeze the first spring 11. Since the first spring 11 is in contact with the weight sensor 10, the weight sensor 10 can display the received weight value on the display 9. The larger the value on the display 9, the greater the deformation. At the same time, the weight sensor 10 will also transmit information to When the value exceeds the preset value in the controller 8, the controller 8 will control the alarm 12 to sound an alarm to remind the surrounding personnel, thereby achieving automatic monitoring without the need for construction personnel to climb and inspect regularly, which is very convenient. After use, the clamping structure 6 is removed from the bracket 1, and then the device is inverted so that the telescopic cover 4 faces down. Then, the threaded nail 20 is rotated to lock the top of the threaded nail 20 back into the slot 18, fixing the movable plate 7 to prevent the alarm from sounding during movement. When the device length is insufficient, the limit rod 15 is pulled outward to pull the top of the limit rod 15 out of the limit groove 13. At this time, the movable rod 5 can be pulled out of the telescopic cover 4. When the appropriate length is adjusted, the limit rod 15 is released, and the second spring 17 will automatically reset the limit rod 15, locking the top of the limit rod 15 back into the limit groove 13, fixing the movable rod 5, thereby completing the length adjustment of the device.
