Description

Technical Field

[0001] This utility model relates to the field of template support monitoring technology, specifically a deformation monitoring device for tall template supports. Background Technology

[0002] With my country's economic development, a large number of projects such as bridges, buildings, and underground spaces are being constructed, and tall formwork plays a crucial role in these projects. However, working at heights poses significant safety risks. After installation specifications require the use of scaffolding, real-time monitoring of scaffolding displacement and early warning of potential hazards become particularly important.

[0003] A deformation monitoring device for tall formwork supports, disclosed in announcement number CN204881633 U, includes scaffold pipes, electrical conduits, and a red laser pointer. The red laser pointer is fixed inside the electrical conduit, which is placed inside the scaffold pipe. Filler is provided between the electrical conduit and the scaffold pipe, and fasteners are provided on the outside of the scaffold pipe. This invention features a simple structure, inexpensive lasers, and reusable lasers. The number of lasers can be deployed to observe as many points as desired; regardless of the location of the observation points, as long as the gap between the horizontal and vertical uprights of the scaffold is accurately located, the laser beam can penetrate. It allows for all-weather observation, making it particularly suitable for projects involving nighttime concrete pouring. Observers do not need to approach the formwork area; they can determine the formwork deformation by observing the projected light spot. One person can observe multiple points simultaneously, or multiple people can observe a single point simultaneously.

[0004] However, the aforementioned devices still have some shortcomings in use. Relying on manual observation not only consumes a lot of manpower and time, but also has a low measurement frequency, making it impossible to capture minute deformations of the support in a timely manner, thus failing to meet the needs of real-time monitoring. Moreover, installation and debugging are difficult, requiring professional technicians to operate, which increases construction and time costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a deformation monitoring device for tall formwork supports. This solves the problems of relying on manual observation, which is not only labor-intensive and time-consuming, but also has a low measurement frequency, making it impossible to capture minute deformations of the support in a timely manner and failing to meet the needs of real-time monitoring. Furthermore, the device is difficult to install and debug, requiring professional technicians to operate, which increases construction and time costs.

[0006] This utility model provides the following technical solution: a deformation monitoring device for a tall template support, including an upper fixed plate and a lower fixed plate. There are two upper fixed plates and two lower fixed plates, and both are semi-circular. The surfaces of the two upper fixed plates and the two lower fixed plates are provided with mounting grooves, which match the support. The lower surfaces of the two upper fixed plates are attached with reflective sheets, and the upper surfaces of the two lower fixed plates are equipped with multiple photoelectric sensors.

[0007] A combination assembly is provided between the two upper fixed plates and between the two lower fixed plates, and a locking assembly is provided on the upper surface of the two upper fixed plates and the lower surface of the two lower fixed plates.

[0008] Preferred technical solution 1: The combined component includes two insert blocks fixedly connected to one side of one of the upper fixed plates and one of the lower fixed plates, and two slots matching the insert blocks are opened on one side of the other upper fixed plate and the other lower fixed plate.

[0009] Preferred technical solution 2: The upper surface of the upper fixed plate with the slot and the lower surface of the lower fixed plate are each provided with a set of movable grooves. Each movable groove is slidably fitted with a locking rod. Each insert has a locking groove on its surface that matches the locking rod. A spring is fitted on one outer end of each locking rod. A pull plate is fixedly connected between the outer ends of each set of locking rods.

[0010] Preferred technical solution 3: The locking assembly includes a fixing plate fixedly connected to the upper surface of the two upper fixing plates and the lower surface of the two lower fixing plates. Each fixing plate has a threaded hole on its surface, and a screw is threaded into the interior of each threaded hole. A clamping plate is rotatably installed at one end of each screw. Each fixing plate has a set of limiting grooves on its surface, and a limiting rod is slidably fitted into the interior of each limiting groove. Each set of limiting rods is fixedly connected to the corresponding clamping plate.

[0011] Preferred technical solution four: The clamp is an arc-shaped clamp that matches the bracket, and a rubber pad is adhered to the surface of each clamp, and the surface of each rubber pad is provided with anti-slip texture.

[0012] Preferred technical solution five: an audible and visual alarm light is provided on the upper surface of one of the upper fixed plates, the photoelectric sensor is electrically connected to the audible and visual alarm light, and both the photoelectric sensor and the audible and visual alarm light are connected to an external power source.

[0013] Compared with the prior art, this utility model provides a deformation monitoring device for tall template supports, which has the following beneficial effects: In use, two upper fixing plates are installed on the upper end of the support. Then, the pull plate is pulled, and the insert of one upper fixing plate is inserted into the slot on one side of the other upper fixing plate. The pull plate is then released, causing the spring force to drive the locking rod into the slot on the insert, thus initially installing the two upper fixing plates on the support. Then, by rotating the screws on the two upper fixing plates, two clamping plates are driven to clamp and fix the support, making the two upper fixing plates more stable and preventing slippage. Then, the same... The two lower fixing plates are installed at the lower end of the bracket in this manner to complete the installation. During monitoring, the photoelectric sensor emits a signal to the reflector for reflection. When the bracket deforms, the deformed side will bulge out and block the signal light path. The photoelectric sensor will not receive the reflected signal and will then activate, outputting a switch control signal to the audible and visual alarm light to activate the alarm and provide a reminder. This device can monitor the deformation of the bracket and issue an alarm in a timely manner when deformation occurs. At the same time, the device can be quickly and easily installed on the bracket for convenient installation and use. Attached Figure Description

[0022] Example 3: The difference between this example and Example 1 is that the upper surface of the upper fixed plate 1 with slot 7 and the lower surface of the lower fixed plate 2 are each provided with a set of movable slots 8. Each movable slot 8 is slidably fitted with a locking rod 9. Each insert 6 is provided with a locking groove 10 that matches the locking rod 9. A spring 11 is fitted on one side of each locking rod 9. A pull plate 12 is fixedly connected between the outer ends of each set of locking rods 9.

[0023] Example 4: The difference between this example and Example 1 is that the locking assembly includes a fixing plate 13 fixedly connected to the upper surfaces of the two upper fixing plates 1 and the lower surfaces of the two lower fixing plates 2.

Each set of limiting rods 18 is fixedly connected to the corresponding clamping plate 16.

[0024] Example 5: The difference between this example and Example 1 is that the clamping plate 16 is an arc-shaped clamping plate that matches the bracket, and a rubber pad is adhered to the surface of each clamping plate 16, and the surface of each rubber pad is provided with anti-slip texture.

[0025] Example 6: The difference between this example and Example 1 is that, in this example, an audible and visual alarm light 19 is provided on the upper surface of one of the upper fixed plates 1, and the photoelectric sensor 5 is electrically connected to the audible and visual alarm light 19. Both the photoelectric sensor 5 and the audible and visual alarm light 19 are connected to an external power supply.

Then release the pull plate 12 so that the spring 11 causes the locking rod 9 to be inserted into the slot 10 on the insert block 6, thus initially installing the two upper fixing plates 1 on the bracket.

During monitoring, the photoelectric sensor 5 emits a signal to the reflector 4 for reflection. When the bracket deforms, the deformed side will bulge out and block the signal light path. The photoelectric sensor 5 will not receive the reflected signal and will then activate, outputting a switch control signal to the audible and visual alarm light 19 to activate the alarm and provide a reminder. This device can monitor the deformation of the bracket and issue an alarm in a timely manner when deformation occurs. At the same time, the device can be quickly and easily installed on the bracket, making it convenient for installation and use.
