Description

A multifunctional rebar detection device Technical Field

[0001] This utility model relates to the field of rebar measurement technology, specifically a multifunctional rebar detection device. Background Technology

[0002] Rebar weight deviation is an indicator that measures the difference between the actual weight and the theoretical weight of rebar, and it is of great significance in rebar inspection. The following are the inspection steps:

[0003] Sample selection: Randomly cut a certain number of samples from different coils of steel bars. The sample length is generally not less than 500 mm, and the straightness of the sample should be ensured.

[0004] Weighing: Weigh the actual weight of the sample using a weighing instrument with the required accuracy. The accuracy of the weighing instrument should meet the measurement requirements, generally accurate to 0.1g or higher.

[0005] Calculation: Calculate the theoretical weight of the reinforcing bar based on its nominal diameter and length. Then, calculate the weight deviation of the reinforcing bar using the formula: Weight Deviation (%) = (Actual Weight - Theoretical Weight) / Theoretical Weight × 100%.

[0006] The existing measurement method generally involves measuring the length of multiple sample pieces with a tape measure, calculating the sum of the lengths, and then weighing the total weight of the sample pieces using an electronic scale.
