Abstract
An object of the utility model is to provide a template support operating condition integrated monitoring system for solve monitoring template support operating condition, prevent that the accident from taking place the technical problem who leads to the incident. A comprehensive monitoring system for the working state of a template support comprises a stay wire displacement sensor for monitoring the displacement of the template support; the pressure sensor is used for monitoring the pressure variation of the template support; a frequency measurement sensor for monitoring the vibration frequency of the template support and an optical camera for monitoring the position state of the template support.
Description
Technical Field
The utility model belongs to the technical field of formwork support safety monitoring technique and specifically relates to a formwork support operating condition integrated monitoring system.
Background
The formwork support is an important supporting device for concrete pouring, and the layout of the formwork support belongs to engineering with high risk. During the concrete pouring process, the deformation and stress of the formwork support are basically not monitored by the construction unit, and even if the deformation and stress are monitored by individual construction units, a theodolite, a level, a total station or a manual monitoring method is only adopted. The methods are greatly influenced by the environment, have limited precision, cannot monitor in real time, and cannot early warn in time when danger occurs.
Accidents in formwork support engineering are continuous every year, a large amount of personnel and property loss is caused, and the accidents occur in the concrete pouring process. From the accident seedling head to the accident, the displacement of the template support is small, sometimes only a few centimeters, but the occurrence time is sudden and is dozens of seconds.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a template support operating condition integrated monitoring system for solve monitoring template support operating condition, prevent that the accident from taking place the technical problem who leads to the incident.
The utility model provides a technical scheme that its technical problem adopted is:
a comprehensive monitoring system for the working state of a template support comprises a stay wire displacement sensor for monitoring the displacement of the template support; the pressure sensor is used for monitoring the pressure variation of the template support; a frequency measurement sensor for monitoring the vibration frequency of the template support and an optical camera for monitoring the position state of the template support.
Furthermore, the stay wire displacement sensor is arranged at the top end, the middle part or the bottom end of the template support.
Furthermore, the pressure sensor is arranged at the bottom end of the template support.
Furthermore, the frequency measurement sensor is arranged on the template support.
The optical cameras are arranged on one side, the middle or the opposite side of the template support.
The effects provided in the contents of the present invention are only the effects of the embodiments, not all the effects of the present invention, and one of the above technical solutions has the following advantages or advantageous effects:
1. the dynamic monitoring of videos, the vibration frequency monitoring, the displacement monitoring and the stress monitoring are comprehensively applied in one system, and the four monitoring modes are verified mutually, so that errors and misinformation are avoided.
2. The real-time dynamic monitoring data acquisition can realize 10,000 data points per second, can monitor the deformation, vibration frequency and stress change of the template supporting system in the concrete construction process in real time, and can give an alarm in time for accident and young. The frequency of the template support is used as a mark for determining whether the template support system is safe or not, so that the monitoring mode and content are simplified, and the early warning quality is improved
3. Compared with the traditional manual monitoring, the influence of human factors on the monitoring result is avoided; and the multiple sensors are verified mutually, so that false alarm is reduced, and the alarm precision is improved.

A comprehensive monitoring system for the working state of a template support comprises the template support 1, a stay wire displacement sensor 2, a pressure sensor 3, a frequency measurement sensor 4 and an optical camera 5.
Preferably, the stay wire displacement sensors 2 are arranged at the top end and the easily-deformed position of the template support 1, and the stay wire displacement sensors 2 can also be arranged in the middle or at the lower end of the template support 1. Stay wire displacement sensor 2 is fixed mounting on the displacement measurement fixed bolster of template support 1 one side, and stay wire displacement sensor 2's stay cord is tied up on template support 1, and stay wire displacement sensor 2 is used for monitoring template support 1's displacement volume. The pressure sensor 3 is arranged at the lower end of the vertical rod of the formwork support 1, and the pressure sensor 3 is used for monitoring the pressure variation of the formwork support 1. The pressure sensor 3 is embedded on a pressure base which can be arranged in a base below the formwork support 1. The frequency measurement sensor 4 is arranged on the vertical rod and the cross rod of the template support 1, and the optical camera 5 is arranged on one side, the middle or the opposite side of the template support 1 through a camera support frame and is used for monitoring the position state of the template support 1 in real time. Starting an optical camera to shoot a first monitoring picture before concrete pouring begins, and then continuously monitoring; when the image different from the first image appears in the picture, the second and later pictures are taken, and the abnormal signal is transmitted in real time.
Although the specific embodiments of the present invention have been described with reference to the drawings, the present invention is not limited thereto, and various modifications or variations that can be made by those skilled in the art without inventive labor are still within the scope of the present invention.
