Its concrete solution is as described below:
A measuring method for accurate control caterpillar gate embedded part coplane degree, comprises the following steps:
1) by after embedded part hoisted in position also preliminary adjustment, transit or total powerstation are placed in the position, measuring basis reference mark of setting;
2) magnet base is positioned on embedded part workplace to be measured, evenly to set up an office layout by embedded part short transverse, and mark intends the position measured;
3) vernier caliper is close to magnet base, the root of vernier caliper is close to embedded part surveying work face, and the scale of vernier caliper is towards transit or total powerstation eyepiece viewing position;
4) utilize the eyepiece cross-hair of transit or total powerstation to find the scale mark of vernier calliper, confirm transit or vernier caliper graduation position corresponding to total powerstation eyepiece, and read the numerical value of vernier caliper;
5) repeat step 2-4, measure other each check point of embedded part successively, the reading difference of each check point of the vernier caliper obtained is the verticality difference of embedded part;
6) repeat above-mentioned steps and carry out measurement opposite side embedded part workplace each point reading, the vernier caliper reading difference of both sides is the difference of embedded part coplane degree, according to the difference of the coplane degree and verticality of determining embedded part, predetermined adjustment position is reached to embedded part adjustment.
Further, the reference mark of measuring basis described in step 1) is as embedded part adjustment coplane degree and the surveying instrument positioning datum point of verticality, and its position is less than the measuring distance of vernier caliper apart from the reference field vertical range of embedded part to be adjusted;
Further, the aids such as pointer are adopted to assist the scale mark position confirmed on vernier caliper in step 4).
Adopt the method can guarantee that the installation accuracy of caterpillar gate embedded part reaches designing requirement, effective solution caterpillar gate embedded part verticality and the adjustment of coplane degree accuracy class up to 0.1mm and the technical requirement of measurement, highest detection accuracy class can reach 0.02mm, and duplicate measurements fiduciary level is high, improve work efficiency, have safe and reliable, easy to operate feature.
Can ensure that the precision of discrete embedded part its verticality and coplane degree in installation process is controlled by this measuring method, facilitate the quality control in high precision embedded part mounting and adjusting process, inspection and the reinspection after reinforcing and examination.The relative classic method of this method, there is the advantages such as structure is simple, easy to operate, measuring accuracy is easy to guarantee, duplicate measurements repeatability is good, handling safety, be suitable for the embedded part verticality of similar structures pattern and accuracy requirement and the requirement of coplane degree mounting and adjusting and inspection and examination.
