Abstract
The invention discloses a calibration test piece for detection of a steel-bar protecting layer. The calibration test piece comprises cuboid concrete, all the surfaces of the concrete are smooth surfaces, a plurality of steel bars are inserted in the concrete, and the steel bars are horizontally placed in the concrete at different heights. The cuboid concrete with the smooth surfaces is adopted, each steel bar is horizontally arranged in the concrete, and the horizontal height difference between every two adjacent steel bars is 10 mm. Thus, a detector for detecting the depths of steel bars can be calibrated through the calibration test piece rapidly and conveniently.
Description
Technical field
The present invention relates to a kind of cover to reinforcement detects with calibration test specimen.
Background technology
At present, need to built-in fitting, carry out the detection of the reinforcing bar degree of depth, be generally to detect by detector, but because frequency of utilization is more, detector there will be the deviation in data, the Weights and Measures Bureau that need to regularly deliver to appointment goes to proofread and correct, the time of proofreading and correct is long, has affected the work detecting.
Summary of the invention
The object of the invention is in order to overcome above deficiency, provide a kind of cover to reinforcement simple in structure, use to detect with calibration test specimen.
Object of the present invention is achieved through the following technical solutions: a kind of cover to reinforcement detects with calibration test specimen, comprises the concrete of rectangular parallelepiped, and the surface of concrete is shiny surface, is inserted with many reinforcing bars in concrete, and many reinforcing bars are placed in concrete with different height levels.
Further improvement of the present invention is: the distance between first reinforcing bar and the upper surface of concrete is 10mm, and the level height distance between every two adjacent reinforcing bars is 10mm.
Further improvement of the present invention is: the number of reinforcing bar is 6-8 root.
The present invention compared with prior art has the following advantages: the present invention adopts ganoid rectangular parallelepiped concrete, each root reinforcing bar is all horizontally set in concrete, and the level height distance between every two adjacent reinforcing bars is 10mm, like this, detecting the detector of the reinforcing bar degree of depth can proofread and correct by the present invention, efficient and convenient.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Number in the figure: 1-concrete, 2-reinforcing bar.
embodiment:
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As showing cover to reinforcement of the present invention, Fig. 1 detects a kind of embodiment with calibration test specimen; the concrete 1 that comprises rectangular parallelepiped; the surface of concrete 1 is shiny surface; in concrete 1, be inserted with many reinforcing bars 2; many reinforcing bars are placed in concrete 1 with different height levels; distance between first reinforcing bar 2 and the upper surface of concrete 1 is 10mm, and the level height distance between every two adjacent reinforcing bars 2 is 10mm, and the number of reinforcing bar 2 is 6-8 root.
The present invention adopts ganoid rectangular parallelepiped concrete, each root reinforcing bar is all horizontally set in concrete, and the level height between every two adjacent reinforcing bars is apart from being 10mm, like this, detecting the detector of the reinforcing bar degree of depth can proofread and correct by the present invention, efficient and convenient.
