A method for measuring the thickness of light steel keel coating or coating for construction

Abstract

The invention discloses a method for measuring the thickness of light steel keel coatings or coatings used in buildings, and belongs to the technical field of building material detection. S1) Section processing: pretreatment such as grinding and polishing of the section to be measured of the light steel keel for construction; S2) Calibration: Calibration of the 3D microscopic system; S3) Shooting: Shooting of the section to be measured of the light steel keel for construction; S4) Analysis and processing: the processing terminal displays the photo of the section to be measured of the light steel keel for construction, and substitutes the effective coefficient k' and line distance d' into the standard surface h=f(d,k) to obtain the thickness h of the part to be measured '. The invention can quickly and accurately measure the thickness of the light steel keel coating or plating layer used in buildings, and can measure continuously without being affected by factors such as the size, shape, and measurement conditions of the object to be measured, especially environmental conditions, and can eliminate human errors. More accurate than traditional pixel-by-pixel methods.

Description

technical field [0001] The invention relates to the technical field of building material detection, in particular to a method for measuring the thickness of light steel keel coatings or coatings for buildings. Background technique [0002] At present, the use of light steel keels for construction in my country is very common, from public buildings to ordinary people's residences. In the initial stage of development and production of light steel keels for construction in my country, the Japanese system, the Australian-American system and the original West German system were basically adopted. Now various systems have been integrated in the production process, and the development momentum is rapid. However, due to the gradual development of the technology of light steel keels for construction and the expansion of the market year by year, some new types of keels have gradually eliminated some old types. [0003] The thickness of the double-sided galvanized layer is an importan...

Problems solved by technology

[0004] The traditional method of measuring by comparing the corresponding relationship between the photo pixels and the actual size has a large human error, because different human eyes have different resolution capabilities, and the positions of the measurement points selected by different human eyes are different, resulting in the final thickness measurement results. error
