SUMMERY OF THE UTILITY MODEL
The utility model relates to an overcome prior art and measure the inconsistent inaccurate problem that leads to measuring of stuck point at every turn, provide a metal and bury formula crack measurement mark, can avoid measuring equipment to put the measuring error that angle and stuck point inconsistency caused when measuring many times, improve measured data's the degree of accuracy.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a formula crack measurement sign is buryyed to metal, characterized by, includes metal screw, metal nut, metal screw includes prism screw column cap and full silk screw column body, and full silk screw column body is connected to the one end of prism screw column cap, and the other end surface center of prism screw column cap is equipped with measures the draw-in groove, and metal nut is hollow cylinder, and metal nut is equipped with the internal thread, and a bottom surface of metal nut is equipped with the cross grooving, and the metal nut surface is equipped with the net recess.
Adopt special triangular prism structure, need special fastening device can fasten, improved stability, simultaneously for improving measurement accuracy, expose the terminal surface center at the metal mark and set up the measurement draw-in groove, the accurate quick stuck point of measuring equipment such as slide caliper of being convenient for.
Preferably, the metal screw and the metal nut are both made of corrosion-resistant high-strength metal alloy materials. Guaranteed the utility model discloses a durability, life increases.
Preferably, the diameter of the metal screw cap is less than 8mm, and the length of the metal screw cap is less than 50 mm. The damage to the original structure after the metal embedded crack measuring mark is installed is greatly reduced.
Preferably, the triangular prism screw head is provided with a protective cover. The protection is measured the draw-in groove, avoids measuring the draw-in groove and suffers external force or natural destruction.
Therefore, the utility model discloses following beneficial effect has: (1) under the high-precision measurement environment, the measurement error caused by inconsistent placing angles and clamping points when the measurement equipment is used for measuring for multiple times can be avoided, the accuracy of measurement data is improved, and the cost input is reduced; (2) the metal embedded type crack measuring mark is adopted, the metal nut is arranged in the metal embedded type crack measuring mark, the metal screw can be fastened, and the stability of the crack measuring metal mark is guaranteed.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description.
As in the embodiment shown in figures 1-8,
a metal embedded type crack measuring mark comprises a metal screw rod 6 and a metal screw cap 7, wherein the metal screw rod 6 and the metal screw cap 7 are both made of corrosion-resistant high-strength metal alloy materials. The diameter of the metal screw cap 7 is less than 8mm, and the length is less than 50 mm. The metal screw 6 comprises a triangular prism screw column head 11 and a full-thread screw column body 12, the full-thread screw column body 12 is connected to one end of the triangular prism screw column head 11, a measuring clamping groove 10 is arranged in the center of the surface of the other end of the triangular prism screw column head 11, and a protection cover 5 is configured. The metal nut 7 is a hollow cylinder, the metal nut 7 is provided with internal threads, a cross-shaped cutting groove 9 is formed in the bottom surface of the metal nut 7, and a grid-shaped groove 8 is formed in the outer surface of the metal nut 7 and used for forming strong friction force with the interior of the wall 4. During the use according to actual metal nut 6 diameter and length adopt suitable electric drill brick head at one side trompil of crack 1 on wall body 4, then hit into metal nut 7 after clear hole is accomplished, then with metal screw 6 screw in metal nut 7 to utilize special prism spanner fastening, repeat above-mentioned installation operation and install the formula crack measurement sign of metal buryying in the opposite side of crack 1, and make the measurement draw-in groove 10 center of both sides be in same water flat line. After the installation is finished, a vernier caliper 3 chuck is inserted into the measuring clamping groove 10 and is tightly pressed without a gap, the distance between a group of initial crack measuring mark values is read, and the subsequent measuring method is the same for each time.
