[China Instrument Network Instrument R&D] Recently, the length of the Hubei Academy of Metrology, a professional scientific research project “Development of a Calibration Device for Quality Control of Construction Projects†has been reviewed by experts and successfully completed.
The construction project quality detector is mainly used in the quality inspection work of engineering construction, decoration and decoration, bridge construction, equipment installation and other areas of construction and acceptance inspection. The inspection objects include the verticality, flatness, right and left corners, and frame pairs of the building walls. Corner length difference, clearance, brick mortar saturation, slope, etc. Therefore, calibration of the quality inspection of the construction project to ensure that its detection capability meets the requirements of the work is of great significance to ensure the quality and safety of the construction project.
At present, the main problem in the calibration of construction engineering quality detectors is that the operation is inflexible and the calibration efficiency is not high. The aforementioned calibration device is a set of devices recalibrated according to the technical requirements of the National JJF1110-2003 Calibration Standard for Construction Quality Detector Sets. The device can not only solve the clamping problem of the detected ruler, but also ensure that the detected ruler can be flexibly rotated along the measuring axis while being clamped, thus ensuring the accuracy and stability of the calibration value. Repeatability.
The device makes up for the inadequacy of ordinary calibration methods for construction quality detectors. It not only increases accuracy and reliability, but also has simple operation and easy application. It will surely play an active role in the calibration of domestic construction quality detectors.
