Specific embodiment
For the feature and advantage of this patent can be clearer and more comprehensible, 2 embodiments are cited below particularly, are described in detail below:
The composition of the present embodiment will be intended to: in the relatively fixed setting detection direction of 400 structure of upright bar of high-supported formwork structure
The orthogonal longitudinal optical fiber inclinometer 111 of projection in the horizontal plane and lateral optical fiber inclinometer 112.
As shown in Figure 1, since the connecting portion of high-supported formwork structure and concrete blinding 200 is easiest to that unstable failure occurs
Danger, once run-off the straight, is nearby arranged monitoring point here, sensitivity and practicability are most strong, therefore, the utility model 2
A embodiment selects at this as monitoring point installation site 1.
So-called fixed setting opposite with 400 structure of upright bar is not required for longitudinal optical fiber inclinometer 111 and lateral optical fiber inclination angle
Instrument 112 is set up directly in upright bar 400, and as shown in Figure 2 and Figure 3, in the 1st embodiment of the utility model, longitudinal optical fiber inclines
Angle instrument 111 and lateral optical fiber inclinometer 112 are close to be fixed in adjustable support 300 respectively, and are mutually in 90 °, adjustable support
Support 300 is the component being directly supported to concrete blinding 200 with the relatively fixed connection of upright bar 400, adjustable support 300 1
As protrude into 400 steel duct of upright bar and be attached, can appropriate adjustment upright bar 400 whole height.
Due to the construction of adjustable support 300 and 400 connection structure of upright bar, cause herein connecting portion stability with respect to upright bar
400 other positions are poor.Pour the displacement of formwork-support caused by construction loads and mixed mud during mixed mud are self-possessed
Adjustable support 300 is passed to, is easy to cause its inclination, therefore selecting adjustable 300 position of support of upright bar 400 as monitoring point is effect
Best one of the selection of fruit.
As shown in Figure 4, Figure 5, in the 2nd embodiment of the utility model, longitudinal optical fiber inclinometer 111 and lateral optical fiber
Inclinator 112 is close to be fixed in upright bar 400 respectively, is in positioned at the lower part of piece horizon bar 500 in the top, and mutually
90 °, the advantage of this kind of set-up mode is to guarantee to have selected a stronger installation site under the premise of monitoring agility,
Reduce the expenditure of the installation support member.
Other than the selection of above-mentioned installation specific location, the other structures of two embodiments of the utility model do not have
Difference, no longer separately repeats below.
It should be noted that longitudinal optical fiber inclinometer 111 and lateral optical fiber inclinometer 112 need during fixation
It is bonded setting as far as possible with upright bar 400 or adjustable support 300, so as to accurately reflect the tilt condition of upright bar 400.
In terms of device, the utility model is in order to realize warning function: longitudinal optical fiber inclinometer 111 and lateral optical fiber inclination angle
Instrument 112 is connected with subtractor circuit and comparison circuit in turn；Comparison circuit connects alarm；Alarm is in longitudinal optical fiber inclinometer
111 or the difference of tilt angle and initial value that obtains of lateral optical fiber inclinometer 112 acquisition issue alarm when being greater than threshold value.Wherein,
Subtractor circuit and comparison circuit are arranged on single-chip microcontroller；Alarm is loudspeaker.Make upright bar 400 at the inclination angle of both direction in length and breadth
Alarm can be made a sound when variation, directly to remind construction personnel.
For the real-time monitoring for realizing distal end, longitudinal optical fiber inclinometer 111 and lateral optical fiber inclinometer 112 are connected with wireless communication
Number transmitter；Longitudinal optical fiber inclinometer 111 and lateral optical fiber inclinometer 112 are wirelessly transmitted to distal end and connect by wireless signal transmitter
Receiving unit.Remote receiver is generally mobile phone.The transmission modes such as bluetooth, GPRS may be selected in wireless transmission scheme.
The concrete application scheme of the utility model also may be summarized to be following steps:
Step 1: it is longitudinal to be close to fixed setting one in the side of the adjustable support 300 on 400 top of upright bar of high-supported formwork structure
Optical fiber inclinometer 111；
Step 2: being close to fixed setting one laterally in the side of the adjustable support 300 of the side of longitudinal optical fiber inclinometer 111
The projection of the detection direction of optical fiber inclinometer 112, longitudinal optical fiber inclinometer 111 and lateral optical fiber inclinometer 112 in the horizontal plane
It is mutually perpendicular to；
Step 3: when Construction of Supporting is completed in the upright bar 400 of high-supported formwork structure, longitudinal optical fiber inclinometer 111 and lateral optical fiber
The tilt angle of inclinator 112 is set as initial value and stores；
Step 4: longitudinal optical fiber inclinometer 111 and lateral optical fiber inclinometer 112 are inclined with the output of preset data acquiring frequency
Rake angle data, and carry out seeking difference operation with initial value, alarm is triggered if gained difference is greater than threshold value.
In step 3, initial value data is transmitted to remote receiver by wireless signal transmitter；In step 4, it indulges
Tilt angle data are exported with preset data acquiring frequency to optical fiber inclinometer 111 and lateral optical fiber inclinometer 112, and are passed through
Wireless signal transmitter is transmitted to remote receiver.
The working principle that longitudinal optical fiber inclinometer 111 and lateral optical fiber inclinometer 112 are arranged in the present invention is, such as
Shown in Fig. 6, AB is monitoring 400 position of upright bar, vertically and horizontally the respectively vertically and horizontally direction of high-supported formwork structure.It is first read before measurement vertical
To the initial inclination angle of optical fiber inclinometer 111 and lateral optical fiber inclinometer 112 and two sides in length and breadth.When AB monitors upright bar 400
Position run-off the straight under load action, by original AB change in location to the position AB ', AB ' is longitudinal vertical where former AB bar at this time
The AB that is projected as in face is indulged, and AB ' is being projected as AB cross in lateral vertical plane where former AB bar, and the horizontal AB of ∠ B is monitoring upright bar 400
In the change of pitch angle value of transverse direction, it is the change of pitch angle value for monitoring upright bar 400 in longitudinal direction, ∠ B horizontal AB and ∠ that ∠ B, which indulges AB,
It is the change of pitch angle value of the upright bar 400 of two optical fiber inclinometers monitoring in two directions that B, which indulges AB, this kind setting i.e. will not be wrong
Upright bar 400 is crossed to tilt in either direction.
Finally, it should be noted that its measurement of the optical fiber inclinometer that the utility model uses, also referred to as fiber grating inclinator
Precision can reach 0.01 °, and since mixed mud pouring construction has real-time, 400 stress of high-supported formwork support frame upright bar becomes in real time
Change, high-precision optical fiber inclinometer can more delicately capture the sign before high-supported formwork support frame unstable failure.
This patent is not limited to above-mentioned preferred forms, anyone can obtain other each under the enlightenment of this patent
The high-supported formwork structure monitoring device of kind form, all equivalent changes and modifications done according to present utility model application the scope of the patents, all
The covering scope of this patent should be belonged to.
