Description
Technical field
The utility model relates to building settlement detection field, is specifically related to a kind ofly can improve building settlement measuring accuracy and fiduciary level can reduce again the laser measurement building settlement device measuring cost.
Background technology
Along with the quickening of socioeconomic fast development and urbanization process, quantity and the number of plies of buildings constantly increase, the sedimentation of buildings is inevitable, due to the version of buildings and the difference of foundation form, the settling amount that buildings produces is also just different, if the settling amount of buildings is excessive or produce non-uniform settling, buildings can produce security performance and the tenure of use that crack affects structure, serious meeting causes structural damage, and necessity and the importance of therefore building settlement measurement are further obvious.The settlement monitoring mode of buildings conventional at present has two classes, and the first kind is conventional geodetic surveying, as reference measurement; Equations of The Second Kind is modern surveying method, utilizes sensor settling amount to be converted to other signals and carries out settlement measurement.The problems such as said method ubiquity measuring accuracy and fiduciary level is low, production cost is high, complicated operation.
Utility model content
For solving the above-mentioned problems in the prior art, the utility model provides a kind of can improve building settlement measuring accuracy and fiduciary level can reduce again the laser measurement building settlement device measuring cost, can be used for carrying out Real-Time Monitoring process to the sedimentation of buildings, be convenient to Timeliness coverage abnormal.
A kind of laser measurement building settlement device, it comprises level crossing with a scale, generating laser, level ground level crossing and the level crossing that is vertically fixed on tested skin face after being fixed on original ground and sedimentation, the laser incident angle of laser transmitter projects is α, level crossing with a scale and the angle on ground are 90 ° of-α, wherein, 0 ° of < α <90 °, the level crossing be vertically fixed on tested skin face is fixed on the position that can receive reflection ray.
As preferably, level crossing with a scale is fixed on the stable adjacent buildings of sedimentation.
As preferably, generating laser is arranged on level crossing with a scale.
The utility model compared with prior art, has following characteristics:
(1) described device can make full use of the high directivity of laser, high monochromaticity and high brightness and realize contactless remote measurement, and the precision measured is relative with fiduciary level improves;
(2) described device construction technology is simple, easy to operate and cheap.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of laser measurement building settlement device described in the utility model.
The level crossing that Reference numeral shown in figure: 1-is with a scale, 2-generating laser, 3-level is ground level crossing after being fixed on original ground and sedimentation, and 4-is vertically fixed on the level crossing on tested skin face, 5-original ground, ground after 6-sedimentation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of laser measurement building settlement device, it comprises level crossing 1 with a scale, generating laser 2, level be fixed on original ground 5 and sedimentation after level crossing 3 on ground 6 and the level crossing 4 that is vertically fixed on tested skin face, the laser incident angle that generating laser 2 is launched is α, level crossing 1 with a scale is 90 ° of-α with the angle on ground, wherein, 0 ° of < α <90 °, the level crossing 4 be vertically fixed on tested skin face is fixed on the position that can receive reflection ray.Generating laser 2 is arranged on level crossing 1 with a scale.
During use, first level crossing 1 with a scale is fixed, then the level crossing 3 after level being fixed on original ground 5 and sedimentation on ground 6 and the level crossing 4 be vertically fixed on tested skin face are fixed on relevant position, start generating laser 2 and measure laser incident angle α, according to the scale sense data h on level crossing 1 with a scale, the last principle of reflection according to light and geometric relationship draw the relationship delta=h*cos α of the h of settling amount and known reading.
The utility model is not limited to form described in example, and the further expansion that those of ordinary skill in the art makes according to the utility model all falls into protection domain of the present utility model.
