Description

Technical Field

[0001] The utility model belongs to the technical field of high-support formwork, in particular to a high-support formwork bearing safety monitoring device. Background Art

[0002] During the use of high-support scaffolding, if the bearing capacity of the pole is insufficient, it will cause the pole to deform, thus causing the support to collapse. Therefore, it is necessary to test the safety of the high-support formwork bearing capacity to ensure that the bearing capacity of the pole meets the requirements, or once the pole is deformed, the bearing capacity of the pole does not meet the requirements, and it is necessary to remind and take remedial measures to ensure the safety of the structure and personnel.

[0003] At present, as shown in patent CN202211605728.8, a monitoring box is generally set between the top of the pole and the formwork to detect the current axial force value of the pole during the concrete pouring process. However, the monitoring box is erected between the top of the pole and the formwork. Due to the limitation of the box body and the different deformations of the shell and the pole when they are under load, the monitoring error will be large.

[0004] Therefore, there is a lack of a high-support formwork load-bearing safety monitoring device with a simple structure and reasonable design. By setting upper strain gauges, middle strain gauges and lower strain gauges on the vertical poles, the strain gauges and the vertical poles can be deformed synchronously when bearing loads, thereby reducing monitoring errors and realizing multi-position detection in the height direction of the vertical poles.

[0035] The four vertical poles around the vertical pole 1 are circumferential vertical poles 1-3, and the vertical deformation detection module includes a clamping seat 9 mounted on the vertical pole 1, four laser monitoring components arranged along the circumferential direction of the clamping seat 9, and four scales 8 respectively arranged on the circumferential vertical poles 1-3;

[0036] The four laser monitoring components each include an extension plate 10 disposed on the clamp seat 9 , an infrared laser transmitter 11 disposed on the extension plate 10 , and a wireless camera 12 embedded in the protruding end of the extension plate 10 .

[0037] In this embodiment, the collection module includes a clamp 7 arranged on the cross bar 1-1, a supporting plate 6 connected to the clamp 7, and a collector box 5 arranged on the supporting plate 6.

[0039] In this embodiment, the clamp seat 9 includes a first semi-circular plate 9-1, a second semi-circular plate 9-2 and a high-strength bolt 9-3 passing through the ends of the first semi-circular plate 9-1 and the second semi-circular plate 9-2. The inner side surfaces of the first semi-circular plate 9-1 and the second semi-circular plate 9-2 are tightly fitted with the outer side surface of the vertical pole 1.

[0040] In this embodiment, the upper strain gauge 2, the middle strain gauge 3 and the lower strain gauge 4 are arranged on the side wall of the vertical pole to avoid being arranged between the top of the vertical pole and the template. On the one hand, it does not affect the installation of the template and reduces the difficulty of installation; on the other hand, it makes the strain gauge and the vertical pole deform synchronously when bearing load, thereby reducing monitoring errors; secondly, it realizes multi-position detection in the height direction of the vertical pole.

[0041] In this embodiment, four infrared laser emitters and four scales 8 arranged on the circumferential poles 1 - 3 are provided to monitor the central pole 1 and the four circumferential poles 1 - 3 .

[0042] In this embodiment, when used, the upper strain gauge 2, the middle strain gauge 3 and the lower strain gauge 4 are all pasted on the vertical pole 1 to ensure that the strain gauge and the object to be measured are deformed together. In this way, when pouring concrete on the high formwork, when the vertical pole 1 is deformed, the strain gauge will deform along with it. At this time, the resistance wire in the strain gauge will change its resistance due to its mechanical deformation.

[0043] In this embodiment, when used specifically, the upper strain gauge 2 , the middle strain gauge 3 and the lower strain gauge 4 may all refer to the BX120-5AA strain gauge or other strain gauges that can achieve the same function.

[0044] In this embodiment, when used specifically, the strain gauge collector 5-3 can refer to the strain gauge data acquisition module of the brand Pengbai, and is multi-channel, so that the upper strain gauge 2, the middle strain gauge 3 and the lower strain gauge 4 are respectively connected to the strain gauge interface;

[0045] The wireless transmitting module 5 - 4 and the wireless receiving module 5 - 5 are both 433M wireless modules, and they have RS485 interfaces.

[0047] In this embodiment, when it is used specifically, in actual use, the RS485 interface of the strain gauge collector 5-3 and the RS485 interface of the monitoring computer 5-2 can also be connected by wire through the bus.

[0048] In this embodiment, when used, the wireless camera 12 is a WIFI camera, which is wirelessly connected to the monitoring computer 5-2 via WIFI.

[0050] In this embodiment, when used specifically, the infrared laser emitter can refer to conventional emitters in the art, as long as it can project a laser spot.

[0051] In the present utility model, when it is used, the upper strain gauge 2, the middle strain gauge 3 and the lower strain gauge 4 are all pasted on the vertical pole 1. Afterwards, during the process of concrete pouring on the high-support formwork, the upper strain gauge 2, the middle strain gauge 3 and the lower strain gauge 4 monitor the deformation of the vertical pole 1 in real time. When the vertical pole 1 is deformed, the strain gauges are deformed synchronously. The signals detected by the upper strain gauge 2, the middle strain gauge 3 and the lower strain gauge 4 are sent to the collector box 5. The collector box 5 collects the signal values ​​of each strain gauge and sends them to the monitoring computer 5-2 through the wireless transmitting module 5-4 and the wireless receiving module 5-5. The monitoring computer 5-2 receives the signal value. If the measured signal value exceeds the required value, it means that the vertical pole is deformed, that is, the load on the vertical pole 1 in the high-support formwork is unsafe, and the monitoring computer 5-2 sends an alarm through the alarm 5-1.

[0052] Alternatively, four infrared laser transmitters 11 emit lasers to the scale ruler 8 of the circumferential uprights 1-3, and the wireless camera 12 captures the laser irradiation point image and wirelessly transmits it to the monitoring computer 5-2. The monitoring computer 5-2 display screen displays the captured laser irradiation point image. The monitor can tell that the uprights or circumferential uprights have undergone vertical deformation by changing the positions of the irradiation points in the two laser irradiation point images, and the load-bearing on the upright 1 in the high-support formwork is unsafe, so as to take remedial measures and ensure the safety of the high-support formwork load-bearing.

[0053] To sum up, the utility model has a simple structure and a reasonable design. By arranging an upper strain gauge, a middle strain gauge and a lower strain gauge on the vertical pole, the strain gauge and the vertical pole are deformed synchronously when bearing loads, thereby reducing monitoring errors and realizing multi-position detection in the height direction of the vertical pole.

[0054] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
