When in use, only the two side edges of the measuring template are clung to the corners and horizontally placed. At this time, the position of the round hole opposite to the corner is the position of the measuring point, and when the round hole is marked, the round hole is sprayed by adopting a spray tank. After the measuring template is adopted, the using steps are very simple, the measuring points are established very efficiently and accurately, and the labor intensity of workers can be greatly reduced. In addition, because the length and the width of the template body are both more than 550mm, and the distance between the center point of the round hole and two adjacent sides of the diagonal angle of the center point is 500mm, a space is formed between the round hole and the side of the template body, and when the space is used for preventing spraying, paint is sprayed outside the template, and the observation of a measuring point is influenced.
Furthermore, each right angle of the template body and the middle part of the template body are provided with a hollowed-out number, each hollowed-out number consists of a first hollowed-out part and a second hollowed-out part, a partition plate is arranged between the first hollowed-out part and the second hollowed-out part, the partition plate is round or square, and the partition plate and the template body are integrally formed; the round holes are formed in the partition plate.
