一、检定台概况在桥梁制造业中,大部分尺寸的测量都是通过钢卷尺来实现的。由于钢卷尺的精度及检定精度较低,因而大尺寸量值不统一的矛盾已在生产中明显暴露出来。为了保证大尺寸的量他统一准确,我们在防空洞内设计建造了50m钢卷尺检定台,可对各种规格的钢卷尺进行检定。洞内温度比较稳定,夏季最高温度为23℃,冬季最低温度为8℃。一般在春、夏、秋三个季节均可进行检定工作。
First, the test station overview In the bridge manufacturing, most of the measurement of dimensions are achieved through the steel tape measure. Due to the low accuracy and accuracy of the steel tape measure, inconsistencies in the values of large dimensions have been clearly revealed in production. In order to ensure that the large size of his uniform and accurate, we designed and built in the air-raid shelves 50m steel tape test station, a variety of steel tape ruler can be tested. Cave temperature is relatively stable, the maximum temperature in summer 23 ℃, winter minimum temperature of 8 ℃. Generally in spring, summer, autumn three seasons can be verified.
