Description
Technical field
The present invention relates to the device of a kind of Deformation Monitoring seam both sides agent structure sliding deformation amount.
Background technology
Due to engineerings such as large-scale construction of structures engineering or subterranean tunnels in use, by periphery construction, naturally drop
Water, earthquake, blast etc. are artificial or the impact of natural cause, and the differential settlement occurred in various degree known from experience by foundation soil or the soil body moves
Moving, the agent structure of engineering can occur entirety or the sedimentation and deformation of local.For structural safety, in engineering design and construction process
In, all can be arranged as required to the movement joint of the types such as aseismatic joint, subsiding crack, expansion joint.When deforming, movement joint both sides
Structural elements vertically and two horizontal direction generation Relative Displacement shiftingizations, the vertical changing of the relative positions (Z-direction phase para-position can i.e. occur
Move), the horizontal changing of the relative positions (X-direction relative displacement), level interval change (Y-direction relative displacement).At present Engineering Structure Distortion is stitched
The monitoring means of both sides agent structure deformation is: installation position each with vertical direction displacement sensor or slit gauge in the horizontal direction, logical
Cross sensor and directly measure the relative deformation of both sides agent structure.
At present, Deformation Monitoring stitches the both sides vertical changing of the relative positions of agent structure (Z-direction relative displacement), (X-direction is relative in the horizontal changing of the relative positions
Displacement) time, one horizontal displacement sensors to be set at deformation joint, a vertical displacement sensor, and by sensor two ends
It is separately fixed in the structure of movement joint both sides, catches the relative shift of movement joint both sides agent structure.
Above-mentioned prior art is primarily present following two point defects: (1) due to the mounting bracket of existing sensor is all
Being fixed in the agent structure of both sides, when movement joint both sides agent structure occurs the relative changing of the relative positions, sensor can occur systematic error,
Monitoring Data is caused to be made mistakes.As a example by only there is the X-direction changing of the relative positions, the horizontal displacement sensors that deformation joint is arranged can stretch
Or contraction distortion, the data monitored are X-direction sliding deformation amounts accurately, but simultaneously as the two of vertical displacement sensor
Position between individual mount point there occurs change, and the distance between two mount points becomes big, and vertical displacement sensor there will be stretching
Deformation, there is the vertical changing of the relative positions at occurred level in the display structure of mistake while the changing of the relative positions.In like manner, only there is the vertical changing of the relative positions
Time, horizontal displacement sensors also can show that the level of there occurs is to the changing of the relative positions.When there is the sliding deformation of both direction, sensor
Data there will be bigger error, and then the accurate analysis that influence technique personnel are to structure detection data.(2) monitoring both direction
Sliding deformation two sensors need to be used respectively both direction to be monitored, the data acquisition of two sensors needs to take
Two data channel on Acquisition Instrument.Monitoring device takes up room the biggest simultaneously, and especially in subterranean tunnel, monitoring of structures becomes
During shape, sensor is each perpendicular to tunnel structure surface and installs, and passes through tunnel and uses and all can cause certain shadow after installation
Ring.

In addition, it is necessary to explanation, when installing the device of above-mentioned Deformation Monitoring seam both sides agent structure sliding deformation amount,
In addition to foregoing description content, also need to meet following condition: be arranged on by double-shaft tilt angle sensor on sensor installing plate, make double
Two angle monitor directions of axial rake sensor are parallel with the long limit of sensor installing plate and broadside respectively；Sensor installing plate
The central axis of the axis of symmetry on two long limits of 3 and described connecting shaft 8 is on same perpendicular, and is parallel to each other；Sensor
The bottom of two bolts on installing plate 3 respectively with point cantact in the inclined-plane of corresponding trapezoidal key, and adjust sensor installing plate 3
On bolt length under sensor installing plate 3 so that metallic rod 12 is in level, is arranged at described first horizon bar
Midpoint between the midpoint of the described installation axle 9 of first end of 4-1 and two keyways 11 being arranged on described second horizon bar 5-1
Should be at same level, two the described trapezoidal keys being arranged in two keyways 11 on described second horizon bar 5-1 oblique
Towards upper, and the central axis of the midpoint, inclined-plane of two described trapezoidal keys and connecting shaft 8 is in same level.
After installation, data acquisition can be carried out, the angle rotated according to double-shaft tilt angle sensor, calculate movement joint two
The displacement in X-direction and Z-direction of the side agent structure.Set the first horizon bar 4-1 and the cross-section center of the second horizon bar 5-1
Between level interval be L, the horizontal range of the contact point of connecting shaft 8 axle center and bolt-trapezoidal key is l；Trapezoidal key inclined-plane with
Horizontal plane angle is ψ, and movement joint both sides agent structure 1 is on vertical, i.e. sliding deformation amount in Z-direction is a, movement joint both sides
In the horizontal direction, i.e. sliding deformation amount in X-direction is b to agent structure 1, the angle that double-shaft tilt angle sensor 2 rotates in X direction
Degree variable quantity is α, is β along Y-direction rotational angle variable quantity.
When the changing of the relative positions on movement joint both sides agent structure 1 only occurred level, i.e. X-direction, the mathematical relationship of b with β is:
[b+l (1-cos β)] tg ψ=lsin β.
A=0；
When movement joint both sides agent structure 1 only occurs vertically, i.e. during the Z-direction changing of the relative positions:
A=Ltg α, b=0；
When movement joint both sides agent structure 1 occurred level is with vertical, i.e. when X and the Z-direction changing of the relative positions:
A=(L+c) tg α,
The angle rotated according to above-mentioned formula, double-shaft tilt angle sensor can judge the position of movement joint both sides agent structure in time
Move change.
The device of the Three-direction deformation of the Deformation Monitoring seam both sides agent structure that the present invention provides, it uses double-shaft tilt angle to sense
Device can monitor the change in displacement of the first horizontal direction and vertical direction simultaneously, takes up room little, it is simple to installs and safeguards；It addition,
The double-shaft tilt angle sensor of the present invention and displacement monitoring component and the connection of movement joint both sides agent structure be all indirectly, non-solid
The connection of fixed pattern, when the agent structure generation relative displacement of movement joint both sides, will not be to double-shaft tilt angle sensor and displacement monitoring
Component produces rigid pullling, thus can avoid causing the Systematic Errors of Monitoring Data owing to lacking deformability；Furthermore, this
Invention provides the first support of two kinds of structures and the second support of two kinds of structures, can be respectively used to be arranged on movement joint both sides master
On the horizontal plane of body structure or on vertical plane.
