Scale for quick qualification testing of angle steel for iron tower

The utility model relates to the technical field of angle steel testing devices and provides a scale for quick qualification testing of an angle steel for an iron tower. The scale comprises a scale body. A main plate and an auxiliary plate are fixedly installed parallelly on the left side and the right side of the top surface of the scale body. Parallel separator plates are fixedly installed on the top surface of the scale body between the main plate and the auxiliary plate. The back ends of the main plate, the auxiliary plate and the separator plates are aligned with the scale body. The front ends of the main plate and the auxiliary plate are longer than the front ends of the separator plates respectively. The front ends of the separator plates are distributed from the left to the right as steps. The scale has a reasonable and compact structure and is convenient for use. The scale is quick, accurate and highly precise in measurement. The scale can reduce investment of professional labor and costs. With the scale, the negative deviation values of angle steels of various models can be quickly known, so that negative-deviation iron tower angle steels are prevented from being used for iron tower construction, and the stability of the iron tower.
