Abstract
The invention relates to a calibration rebound device which comprises a striking rod and a cover. The striking rod penetrates through the center of the cover, the cover is arranged outside the striking rod, striking rod side face scale marks are arranged on the side face of the striking rod, and the cover is provided with cover 360-degree scale marks. The striking rod with the scale marks and the cover with the scale marks are adopted, during application, a calibration test needs to be conducted in four directions, before striking in each direction, the striking rod needs to rotate by 90 degrees, in other words, the striking rod side face scale marks are sequentially aligned with the 0-degree scale mark, the 90-degree scale mark, the 180-degree scale mark and the 270-degree scale mark on the cover 360-degree scale marks, striking is continuously conducted three times downwards on a steel anvil, in the striking process, the relative positions of the striking rod side face scale marks and the 0-degree scale mark, the 90-degree scale mark, the 180-degree scale mark and the 270-degree scale mark on the cover 360-degree scale marks are unchanged, the average value of the stable rebound result in each direction is read, calculated and recorded, and when the rebound average value in each direction meets 80+/-2, calibration is qualified. The rebound device can meet the requirement that during the calibration test, the striking rod can accurately rotate by 90 degrees, the requirement is consistent with the standard requirement, and therefore the accuracy of the calibration test is improved.
Description
Technical field
The invention belongs to detection technique field, particularly a kind of calibration reisilometer.
Background technology
At present, after in " concrete intensity with rebound method technical regulation " (JGJ/T23-2011), 4.1.2 bar specifies that reisilometer before detection, calibration test all should be done on riveting stake, and the regulation of this code 3.1.3 article should be met, 4.1.2 provision is explained in illustrating and is illustrated that this is the off-rating in order to ensure in use Timeliness coverage and correction reisilometer, 3.2.2 in bar, 4 regulation calibration tests should divide four direction to carry out, and before the attack of each direction, elastic stem answers 90-degree rotation, and the resilience mean value in each direction all should be 80 ± 2.Existing reisilometer can only rely on the sense organ of testing crew to go to rotate elastic stem in calibration test, the degree of accuracy of elastic stem 90-degree rotation cannot be ensured, even if existing reisilometer resilience mean value in each direction in calibration test is 80 ± 2, also the operation of reisilometer under off-rating is considered as, rebound degree definite value is inaccurate, cause detecting data distortion, impact detects result of determination.
Summary of the invention
The object of the present invention is to provide a kind of calibration reisilometer, reisilometer can be made when calibration test to reach the requirement of the accurate 90-degree rotation of elastic stem, consistent with code requirement, thus improve the accuracy of calibration test.
To achieve these goals, technical scheme of the present invention is as follows.
A kind of calibration reisilometer, comprises elastic stem and block, and described elastic stem is through block center, and block is arranged on elastic stem outside, and elastic stem side arranges elastic stem side scale mark, and block arranges block 360 degree of scale marks.
Elastic stem side scale mark and block 360 degree of scale marks are arranged for depression, fill scale paint in depression.
Elastic stem side scale mark length be not more than reisilometer pin movement time elastic stem end to distance of blocking a shot.
During this application of installation, elastic stem side scale mark is aimed at successively 0 degree, 90 degree, 180 degree, 270 degree scale marks on block 360 degree of scale marks, continuously downwards attack three times on riveting stake respectively, and in attack process, the relative position of 0 degree, 90 degree, 180 degree, 270 degree scale mark on elastic stem side scale mark and block 360 degree of scale marks is constant, then read, calculate, the mean value of the stable resilience result recorded on each direction, the resilience mean value in each direction all meets 80 ± 2, is calibration qualified.
This beneficial effect of the invention is: apparatus of the present invention can make reisilometer reach the requirement of the accurate 90-degree rotation of elastic stem when calibration test, consistent with code requirement, thus improve the accuracy of calibration test.
