Change shape, induces the failure of frame body stability, so that high-supported formwork partial collapse or the whole safety accidents such as topple occur, causes personnel
Injures and deaths and its property loss.
Although country puts into effect various files and code requirement is monitored supporting frame, due to frame body bar jointed mistake
In journey the most sensitive position of stress can not the factors such as pre-control and technology acuracy, cost influence, industry is without simple and fast side at present
Just the method in terms of effective mould bases security monitoring is difficult to prevent the generation of mould bases cave-in accident.
Summary of the invention
The present invention exists in order to solve due to a lack of mould bases security monitoring, in superelevation mould bases work progress because force stability is lost
The security hidden trouble of effect, and then provide a kind of superelevation frame body stability in-situ monitoring method.
The present invention adopts the following technical scheme:
A kind of superelevation frame body stability in-situ monitoring method realizes monitoring, reflex reflector installation based on total station and reflex reflector
In being used as monitoring point on the target monitoring rod piece of superelevation frame body, early warning is determined using the three-dimensional coordinate of total station survey monitoring point
The stability of superelevation frame body.
Specific monitoring method is as follows:
1) the target monitoring rod piece of superelevation frame body is selected；
2) reflex reflector is fixed on each target monitoring rod piece, as monitoring point；
3) survey station point quantity and position are determined on the outside of superelevation frame body according to selected monitoring point, sets up whole station respectively at each measuring point station
The acquisition range intersection of instrument, each survey station point must be able to cover all monitoring points；
4) determine that datum mark, each survey station point at least correspond to two datum marks according to survey station point；
5) pass through the three-dimensional coordinate of each monitoring point of all-station instrument accurate measurement of survey station point；
6) stability that respective objects monitoring rod piece is judged according to measured monitoring point D coordinates value monitoring, if arbitrary coordinate
Value is more than the default higher extreme value of total station, then buzzing prompts.
The distance between any datum mark and survey station point are not less than the maximum value of survey station point and each monitoring point distance.
Survey station point is also equipped with a check datum mark, and the standard of other datum marks is checked using the measurement data for checking and approving point
True property.
The reflex reflector is reflective strip, is protected on target monitoring rod piece by adhesive tape fixation, close under reflective strip
Side or top are equipped with significant color identifier.The bulking block that other congenerous can also be used meets total station as long as being able to achieve
Reflective acquisition data
The target monitoring rod piece include, but is not limited to special-shaped node rod piece, variable cross-section node rod piece, weak node rod piece,
Key node rod piece and main node rod piece can specifically be selected according to construction building type and construction reference.
The invention has the following beneficial effects:
1, the present invention is based on intelligent total station location technology, in the fixed reflective strip in the required position of identified rod piece, using certainly
Moving-target identifying system, completes target search, accurately sights, automatic Observation, obtains the change that frame body changes with upper load in real time
Graphic data, the stability status of the superelevation that gives warning in advance frame body can effectively avoid the generation of safety accident, and forewarning function is significant；
2, can be according to flexible arrangement monitoring point the case where frame body, data are representative strong；
3, this method can apply to the superelevation frame body of different structure form, applied widely, and can be quickly true according to different frame bodies
Determine monitoring point, survey station point and datum mark, do not need to be equipped with dedicated monitoring device, does not also need to be equipped with especially professional personnel, meeting
Total station is operated, frame body monitoring can be completed, operates convenient, quick, safety, economy.
Detailed description of the invention
Fig. 1 is monitoring principle figure of the present invention；
Fig. 2 is setting principle figure of the reflex reflector on monitoring rod piece；
1- superelevation frame body, 2- target monitoring rod piece, 3- reflective strip, 4- adhesive tape.
Specific embodiment
Monitoring principle of the invention is after the completion of bracket is set up, and safety zone (refers mainly to operation construction on the outside of frame body
Safety zone) setting benchmark and survey station point, and set up total station instrument, monitoring point selected (to ensure that instrument is realized on frame body
Intervisibility), fixed reflecting piece carries out initial observation, process observation (real-time early warning), data processing, deformation analysis, and then reach fast
Speed obtains real-time deformation data and super-limit prewarning, takes corresponding measure in time, realizes the purpose of safety in production.
Below by taking certain engineering frame body as an example, specific implementation process of the invention is illustrated:
1, monitoring instrument and precision
This method is using existing intelligent total station (coming card Robot60), and angle measurement 1 second, ranging 1mm+1.5ppm, three-dimension monitor was smart
Spend 1.0mm.
2, monitoring frequency
Frame body has set up observation 1 time, and concreting process is with progress real-time monitoring 1 time, observation 1-2 times after having poured.
3, datum mark, survey station point, layout of the monitoring points
Datum mark is before frame body is set up, and according to on-site actual situations, lays three datum mark (benchmark in Fig. 1 in safety zone
Point 1, datum mark 2 and datum mark 3, one of datum mark, which can be used as, checks datum mark), two survey station point (survey station points in Fig. 1
1 and survey station point 2), and accurate testing three-dimensional coordinate.
The rod piece monitored is needed to set up on 2 survey station points respectively after frame body has been set up according to the selection of frame body layout drawing
Total station, the laser alignment line emitted by instrument lay monitoring point in frame body suitable location and paste firm reflecting piece simultaneously (using glue
Protection is fixed in the measures such as band), while First Observation is carried out immediately, instrument automatic numbering simultaneously records.
4, it monitors
4.1, intelligence sets station: good intelligent total station is set up on survey station point, prism is disposed on datum mark, and station is set by intelligence,
Instrument, which is automatically performed, sets station work.
4.2, pole coordinates lofting: clicking Setting-out procedures, selects monitoring point point number, and instrument sights space point target automatically.
4.3, polar coordinate measurement three-dimensional coordinate: fine sight monitoring point is pressed measurement key and is measured, and instrument automatically records sight
Measured data, and it is poor according to the limit that instrument is set, determine whether each coordinate value transfinites automatically, if transfiniting buzzing prompt.
4.4, when casting process is monitored, monitoring personnel is always maintained at connection with intercom with work surface administrative staff
Network, and according to position is poured, it selects corresponding monitoring point to be observed, if any early warning value is close to or up to, notifies work surface immediately.
5, Data Analysis Services
The data of observation are downloaded, displacement, settling amount, differential settlement are calculated, analyze data, draw settling amount scatter chart.
Using monitoring method of the present invention, it can determine that high-supported formwork frame body is implementing each phase displacement variation, verify computation model
With the accordance of implementation process, and to the type frame body monitor provide directiveness and pre-control.
