Abstract

The invention relates to a verticality detection scale calibration device for a construction quality detector group, which is used to calibrate the zero position error, display value variability, and display value error of the vertical detection ruler of a construction project quality detector group, including a base, The verticality detection ruler installed with the verticality detection ruler is equipped with a positioning structure and a rotation angle calibration mechanism. Through the overall plan, the calibration of the measurement performance of the verticality detection ruler is realized, providing effective measurement technology guarantee for the quality of construction projects, and improving its The method for calibrating metrological performance fills in the gaps in the calibrating technology of construction quality detector groups.

Description

technical field [0001] The invention relates to a calibration device for a verticality detection ruler of a construction quality detector group used for calibrating measurement performances such as zero error, indication value variability, and indication error of a construction engineering quality detector group verticality detection ruler. Background technique [0002] The existing calibration method of the verticality detection ruler of the construction quality detector group is based on "JJF1110-2003 Calibration Specifications for Construction Engineering Quality Detector Group", the calibration items are not perfect, the positioning reference is not reliable, and the calibration method is inconsistent with the use method. Therefore, The existing calibration methods cannot meet the calibration of the indication error of the perpendicularity measuring ruler. [0003] The rapid development of my country's construction industry has put forward higher technical requirements f...
