Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
The deformation displacement of large scale structure test at present needs to set up large-scale bracket, time-consuming and laborious expensive, inconvenient for use and measurement
It is difficult.The configuration of the present invention is simple, operation is convenient, easy to carry, gathers materials on the spot.
Application principle of the invention is explained in detail with reference to the accompanying drawing.
As shown in Figure 1, large scale structure deflection test device provided in an embodiment of the present invention include: attachment device 1, steel cable 2,
Steel tape 3, weight 4, level the band mircrometer gauge 5, large scale structure 6 of truncation.
Attachment device 1 is connected to 6 bottom of large scale structure, and the steel tape 3 of truncation is connect by steel cable 2 with attachment device 1, weight
Object 4 is connected to the lower section of steel tape 3 of truncation by steel cable 2, and level adds mircrometer gauge 5 to assemble to be placed in ground and in suitable distance
It is observed reading.Attachment device 1 and large scale structure 6 pass through the glue connection of quick-drying structure；It is equipped at the top of attachment device 1 and places quick-drying
The interconnecting piece of structure glue, bottom are equipped with the through-hole of connection steel cable 2.
In a preferred embodiment of the invention, the steel tape 3 of truncation is one section intercepted in common steel tape on the market, is taken
Material is convenient；Weight 4 is the actual measurement any weight in place, it is desirable that is that steel cable can be made to keep vertical state and be easy to be connected by steel cable；Water
Quasi- instrument band mircrometer gauge 5 refers to that level mircrometer gauge is installed on level camera lens, makes the reading of level more smart by it
Trueization, general valid reading are 10 times for not filling micrometer level, and the level height of measured object can be accurate to 0.1mm, estimate reading
To 0.01mm.
As shown in Fig. 2, large scale structure deflection test method provided in an embodiment of the present invention the following steps are included:
S201: it needs measurement position to coat quick-drying structure glue in large scale structure bottom, and is mutually glued with attachment device, attachment device
One aperture is arranged at lower part, can connect steel cable；
S202: steel cable one end is connected with attachment device, and the other end is connected with the steel tape of truncation, under the steel tape of truncation
End keeps plummet state by one weight of steel cable suspension, in suitable position placement level band mircrometer gauge, to the steel of truncation
Tape measure is observed reading.
Suitable distance is that level can carry out accurate reading to the steel tape of truncation, within 100 meters.
The use of level includes: the placement, thick flat, aiming, smart flat, five steps of reading of level.(having ready conditions can make
With digital level, digital level is current state-of-the-art level, cooperates special bar code levelling rod, in instrument
The digital imaging system set, the automatic bar code reading for obtaining levelling rod, it is no longer necessary to artificial reading.This instrument can substantially reduce
Operation labor intensity is surveyed and drawn, artificial subjective reading error is avoided, improves measurement accuracy and efficiency.)
1. placement.Placement is to be mounted on instrument on the tripod that can be stretched to be placed between two observation points.It beats first
It opens tripod and keeps height moderate, keep frame head approximate horizontal with eye estimating method and check whether foot prop is secured, then opens instrument container,
Leveling instrument is connected on tripod with connection spiral.
2. thick flat.Thick put down is the sight coarse level for making instrument, sets round level bubble using foot screw and occupy round index circle
Among.Specific method: practiced with instrument.In flattening course, the mobile direction of bubble is consistent with the direction that thumb moves.
3. aiming at.Aiming is to be precisely targeted target with telescope.It is telescope first to distally light ground,
Eyepiece focusing spiral is rotated, keeps crosshair clearest.Fixed spiral is unclamped again, telescope is rotated, makes the connection of sight and foresight
It is directed at levelling rod, tightens fixed spiral.Object lens focusing screw is finally rotated, make levelling rod clearly falls in crosshair plane
On, it is rotated further by final motion screw, the picture of levelling rod is made to be against the side of vertical hair.
4. essence is flat.It is the sight accurate degree for making telescope that essence is flat.Tilting level is equipped with one group of rib on levelling tube top
Level tube bubble both ends can be refracted in the contact level observation window by mirror tube by mirror, if bubble is placed in the middle, bubble both ends
As a parabolic type will be met into, illustrate sight level.If bubble both ends as inconsistent, illustrate that sight is not horizontal.At this moment
Can be made with the micro- spiral of inclining of right hand rotation bubble both ends as complying fully with, instrument can provide a horizontal line of sight, to meet water
The requirement of locating tab assembly basic principle.Note: the moving direction of bubble left-half, it is always inconsistent with the direction of right hand thumb.
5. reading.With crosshair, the reading read on levelling rod is cut.Level is mostly inverted image telescope, and when reading should be by upper
And lower progress.First estimate read grade reading, after quote whole readings.Note that level is had to using step by sequence above
It carries out, cannot overturn, meet bubble adjustment before especially reading, have to carry out before reading.
Calculation Method of Deflection: an initial reading is read with level band mircrometer gauge before non-loading carries, after then loading carries again
It reads once, the difference read twice is deflection value.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
