AI Technical Summary

Technical Problem

Existing construction engineering testing equipment suffers from measurement deviations when detecting the diameter of reinforcing bars due to uneven surfaces, rust, and stains on the reinforcing bars, resulting in unstable laser reflection signals. Furthermore, the grinding effect is poor and adjustments are inconvenient.

Method used

A steel bar diameter detection device for building engineering testing was designed, including components such as an upper shell, support column, measuring mechanism, lifting mechanism, and installation mechanism. Through the combined use of support positioning plate, adjustment plate and limiting plate, stable support and accurate measurement of steel bars can be achieved.

Benefits of technology

It enables precise measurement of rebar diameter, reduces measurement deviation, and improves the accuracy and convenience of testing.
