For cost-saving, facilitate calibration measurement scale, the utility model provides a kind of concrete carbonation depth surveyors' staff.
In order to solve above technical matters, the technical solution of the utility model is: a kind of concrete carbonation depth surveyors' staff, and the sleeve that comprises scale and be actively socketed on described scale outside, described sleeve is stretched out at described scale two ends; Described scale top cover has spring, and described spring upper end is connected with the upper end of described sleeve, and described spring lower end is fixedly connected with described scale, and the position of the corresponding described spring of described scale is provided with scale; Described scale lower end is connected with measurement cutter head by adjustable for height calibrating stem; Described sleeve lower end is provided with the concrete touch panel vertical with the blade of described scale.
As preferably, the xsect of described scale is rectangle or circle.
As preferably, described spring upper end is connected with the upper end of described sleeve by portable plate;
As preferably, described spring lower end is fixedly connected with described scale by fixed head
As preferably, the described calibrating stem nut that has been threaded, it is inner that described nut is fixed on described scale.
As preferably, described measurement cutter head is with a point.
As preferably, described measurement cutter head is cone shape.
As preferably, described concrete touch panel is enclosed within on the blade of described scale.
As preferably, described concrete touch panel is arranged on a side of described scale.
Concrete carbonation depth surveyors' staff provided by the utility model, simple in structure, simple to operate, measurement result is accurate.When tool bit abrasion is measured in described measurement, it is sharp that use instrument will be measured cutter head sharpening, adjust the height of described calibrating stem, and to concrete carbonation depth surveyors' staff, measurement is calibrated, and calibration is convenient, not need to change measurement cutter head and just can reuse, and save cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of concrete carbonation depth surveyors' staff provided by the utility model;
Shown in figure: 1, scale, 2, sleeve, 3, spring, 4, calibrating stem, 5, measure cutter head, 6, concrete touch panel, 7, portable plate, 8, fixed head, 9, nut.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: please refer to Fig. 1, a kind of concrete carbonation depth surveyors' staff, the sleeve 2 that comprises scale 1 and be actively socketed on described scale 1 outside, described sleeve 2 is stretched out at described scale 1 two ends; Described scale 1 top cover has spring 3, and described spring 3 upper ends are connected with the upper end of described sleeve 2, and described spring 3 lower ends are fixedly connected with described scale 1, and the position of the corresponding described spring 3 of described scale 1 (being within the whole stroke of spring 3) is provided with scale; Described scale 1 lower end is connected with and is measured cutter head 5 by adjustable for height calibrating stem 4; Described sleeve 2 lower ends are provided with the concrete touch panel 6 vertical with the blade of described scale 1.
The xsect of described scale 1 is rectangle or circle, is convenient to the hand-held described scale 1 of holding.
Described spring 3 upper ends are connected with the upper end of described sleeve 2 by portable plate 7, by described portable plate 7, to pressing down described sleeve 2, drive described spring 3 parallel to lower compression, improve measuring accuracy.
Described spring 3 lower ends are fixedly connected with described scale 1 by fixed head 8, and fixed head 8 guarantees that in the downward compression process of described spring 3, described spring 3 horizontal directions are stable, improve measuring accuracy.
Described calibrating stem 4 nut 9 that has been threaded, described nut 9 is fixed on described scale 1 inside.By rotating described calibrating stem 4, can adjust the height of described calibrating stem 4, nut 9 is fixed on described scale 1 inside, prevents that calibrating stem described in the use procedure of concrete carbonation depth surveyors' staff 4 is loosening, has avoided the negative effect to measuring accuracy.
Described measurement cutter head 5, with a point, can be specifically cone shape or pointed end face, and described measurement cutter head 5 can accurately be aimed at.
Described concrete touch panel 6 is enclosed within on the blade of described scale 1, is convenient to the measured hole of described concrete touch panel 6 comprehensive engagements concrete surface around, improves measuring accuracy.
Described concrete touch panel 6 is arranged on a side of described scale 1, is convenient to described concrete touch panel 6 and moves up and down under described sleeve 2 drives, and makes concrete carbonation depth surveyors' staff easy to operate.
Described scale 1 calibration is 0.25mm.
Carbonation depth value is measured: can adopt surface, proper implements Ce district to form the hole of diameter 15mm, its degree of depth should be greater than concrete carbonization depth.Powder in hole and chip should be except clean, not handy scrub water, should adopt concentration is the edge that 1% phenolphthalein alcoholic solution drops in hole inwall simultaneously, when carbonization is known with not carbonization boundary line, again with concrete carbonation depth surveyors' staff provided by the utility model measure carbonization with carbonated concrete interface not to the vertical range of concrete surface, cutter head 5 heads be will measure and carbonization and carbonated concrete interface not aimed at, to pressing down described portable plate 7, drive described sleeve 2 to move downward, until the concrete touch panel 6 of described sleeve 2 lower ends contacts with concrete surface, read the compressed numerical value of described spring 3, be concrete carbonation depth value, measure and should not be less than 3 times, get its mean value, each reading is accurate to 0.5mm.
Carbonated concrete run into 1% phenolphthalein alcoholic solution can variable color, carbonated concrete runs into 1% the phenolphthalein alcoholic solution look that can redden.
Concrete carbonation depth surveyors' staff provided by the utility model, simple in structure, simple to operate, measurement result is accurate.When cutter head 5 wearing and tearing are measured in described measurement, it is sharp that use instrument will be measured cutter head 5 sharpenings, adjust the height of described calibrating stem 4, to concrete carbonation depth surveyors' staff, measurement is calibrated, and calibration is convenient, does not need to change measurement cutter head 5, just can reuse, save cost.
