Background
The core drilling method is widely applied to detection of concrete construction quality, is a method for detecting concrete strength by drilling a core sample from structural concrete by using a special drilling machine, and is a widely popularized effective method for detecting concrete strength in a semi-damaged structure at home and abroad. According to the standard requirement, before the concrete core sample compression-resistant test piece is processed and subjected to a compression-resistant strength test, a vernier caliper is used for measuring the diameters of two mutually vertical positions in the middle of the core sample test piece, and the arithmetic mean value of the measurement is taken as the diameter of the core sample test piece. However, in actual practice, since the measurement position is not on the core sample surface, it is difficult to ensure that the measurement direction of the second diameter is perpendicular to the first measured diameter after the first diameter of the core sample specimen is measured. At present, two diameter positions of a core sample test piece which are perpendicular to each other are generally selected only by visual inspection, and deviation exists, so that the test data are inaccurate. Therefore, a new technical solution is needed to solve the above problems.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a measuring device of concrete core appearance diameter which characterized in that: comprises a main ruler, a vernier, a fastening screw and a measuring jaw;
the main ruler is L-shaped, and the included angle is 90 degrees; the main scale has the same length on both sides and is provided with length scales.
The vernier is positioned by fastening screws, and two sides of the main ruler are respectively provided with a vernier capable of freely moving.
The measuring jaw is a foldable measuring jaw, the length of the measuring jaw can be adjusted, the measuring jaw is perpendicular to the main ruler and is integrated with the vernier, and fastening screws are arranged at the folding positions of the measuring jaw to control the tightness.
The main ruler is made of steel.
The main scale and the measuring jaws are used for fixing the core sample test piece, and the main scale and the measuring jaws clamp four sides of the core sample test piece.
Firstly, selecting a proper measuring claw length on the device according to the diameter of a core sample test piece, screwing a fastening screw, and then sleeving the device on the middle part of the core sample test piece. And then respectively moving the cursors on the two sides of the main scale to clamp the cursors with the surface of the core sample test piece and screwing the fastening screws, and then accurately reading the lengths of the two diameters perpendicular to each other in the middle of the core sample test piece from the scales on the two sides of the main scale, so that the deviation caused by original visual inspection is avoided.
Compared with the prior art, the technical scheme has the following beneficial effects: the measured diameters are the diameters of the two positions which are mutually vertical to the middle part of the core sample test piece, the diameters of the two positions which are mutually vertical to the middle part of the core sample test piece can be accurately and quickly measured and read, and the operation is simple.
