Description
Technical Field
The invention belongs to the technical field of construction of constructional engineering, and relates to a system for monitoring a template support system in real time in the whole process of high formwork construction, in particular to an early warning method of a high formwork real-time safety monitoring early warning system based on a BIM application technology.
Background
With the acceleration of urban development process, in order to meet various use functions and requirements, a large number of high formwork supports appear in public building engineering, road and bridge engineering and steel structure installation engineering. The high formwork has two conditions, the first is a concrete formwork supporting project which is provided with a height of 5m or more, or a span of 10m or more, or a total construction load (a design value of a basic combination of load effects, hereinafter referred to as a design value) of 10KN/m2 or more, or a concentration line load (a design value) of 15KN/m or more, or a height which is larger than a supporting horizontal projection width and is relatively independent of a non-connection component. The second is to set up a height of 8m or more, or a span of 18m or more, or a total construction load (design value) of 15KN/, m2 or more, or a concentration line load (design value) of 20KN or more.
Among the types of safety accidents in building construction, the high formwork is a frequent area of safety accidents. The local or overall collapse of the high formwork support body generally occurs in the period from concrete pouring to concrete final setting, and for the reason, the high formwork safety accident is generally a serious accident of group death and group injury, and the social influence is extremely bad. Therefore, the high formwork safety is always the key point of control in engineering construction.
In the period from concrete pouring to concrete final setting, monitoring of a high formwork support body is one of important measures for avoiding safety accidents, the existing monitoring method mainly depends on manual monitoring, namely, survey staff are arranged to monitor the periphery of the support body by adopting optical instruments such as a total station or a level gauge, and the monitoring frequency is generally 20-30 min/time. When the accumulated change value or the change rate of the monitoring data approaches or reaches an alarm threshold value, a safety emergency group is immediately organized to take emergency rescue measures, and operators are reminded to evacuate emergently through the modes of telephones, interphones, shouting and the like. The monitoring method has the following defects: firstly, the deformation condition in the high formwork support body cannot be monitored, and the monitoring range is lack of comprehensiveness; secondly, the stress condition of the frame body cannot be monitored, and the monitoring standard is single; thirdly, the monitoring frequency is generally 20-30 min/time, and the high formwork cannot be monitored in real time; the existing monitoring mode cannot predict the safety condition of the high formwork, the alarming mode is not timely enough, and once a dangerous case occurs, the emergency measures are started slowly.
The accident is a process of quantitative and quantitative accumulation to a certain degree and finally qualitative change, the potential accumulation time can be long or short, but the occurrence of the story is a moment. Therefore, it is of practical significance to develop a full-automatic system which can monitor the high formwork in real time and early warn the safety condition of the high formwork in advance, and the system is not slow at all.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
firstly, the data monitoring and acquisition module 1 can monitor the stress condition of the high formwork support body in real time and accurately position, and monitoring data are transmitted to the data center processing module 2 through the data communication unit 14.
And the data center processing module 2 is used for processing and analyzing the monitoring data, comparing the monitoring data with an early warning threshold value and transmitting a processing result to the BIM module 3 through the Internet.
And the BIM module 3 is used for establishing a high formwork BIM three-dimensional model according to the CAD drawing, dynamically displaying the high formwork support body according to the actual situation of the site, distinguishing and positioning the dangerous situations of the high formwork support bodies in different areas of the site by using different colors, and simultaneously feeding back the result to the data center processing module 2 through the Internet network.
The instruction unit 25 in the data center processing module 2 is connected to the alarm response module 4, on one hand, controls the on-site acousto-optic alarm unit 41, and on the other hand, pushes information to the client management unit 42.
The video monitoring module 5 can monitor the field operation condition in real time on one hand, and can remotely command field operation personnel to evacuate to a safe area orderly after the response of the alarm response module 4 on the other hand.

The data analysis unit 23 is a core, and analyzes and predicts the stability development state of the high formwork support according to the result obtained by the data processing unit 22, and pre-judges the possibility of the collapse of the high formwork support.

The color distinguishing unit 33 distinguishes the safety states of the high formwork support bodies in different areas by using different colors, when the monitoring data is more than or equal to 90% of the early warning threshold value, the high formwork support body in the area is displayed in red, the BIM module 3 feeds information back to the instruction unit 25 at the moment, and the alarm response module 4 is controlled to respond to prompt the operators to evacuate rapidly; when the monitoring data is more than or equal to 70% and less than 90% of the early warning threshold value, the high formwork support body in the area is displayed to be yellow, the BIM module 3 feeds information back to the instruction unit 25 at the moment, the alarm response module 4 is controlled to respond, the existence of hidden danger is reminded, and operation is carried out after the hidden danger needs to be eliminated; when the monitoring data is less than 70% of the early warning threshold value, the high formwork support body in the area is displayed in green, and the alarm response module 4 is not triggered at the moment.
The invention further improves that: and step three, the GPS positioner 15 arranged on the monitoring point of the high formwork support body can provide accurate positioning coordinates, and the GPS positioner is in one-to-one correspondence with the corresponding position in the BIM three-dimensional model, so that the site with abnormal conditions can be known, and the pertinence and the purpose are better when the countermeasure is taken.
The invention further improves that: in the fourth step, the instruction unit 25 is connected to the alarm response module 4 through a 4G network, on one hand, the on-site acousto-optic alarm unit 41 is controlled to give an alarm, at the moment, two alarm types are provided, and one type is a red alarm which is given when the monitoring data is more than or equal to 90% of the early warning threshold value, so that the operator is reminded to rapidly evacuate to a safe area; the other is a yellow alarm which is sent when the monitoring data is more than or equal to 70% of the early warning threshold value and less than 90%, so that the existence of hidden danger is reminded, and the operation is carried out after the hidden danger is eliminated. On the other hand, the information is pushed to the client management unit 42, so that the management personnel can conveniently and remotely check the information.
The invention further improves that: in the fifth step, the video monitoring module 5 connected with the data center processing module 2 can monitor the field operation condition in real time on one hand, and remotely check and command the orderly evacuation of the operating personnel after the response of the alarm response module 4 on the other hand, and the whole field resource is mobilized to the maximum extent without dead angles, thereby achieving the effects of fast evacuation, smooth road and timely rescue.
