The utility model aims to provide a positioning ruler for the surface of a cylinder, which can improve the positioning precision of a bracket, avoid interference and improve the mounting and construction efficiency of the bracket.
In order to achieve the object of the present invention, the present invention provides a positioning ruler for a cylinder surface, which is used for positioning measurement on a column surface of an upright column, and comprises: an inner arc angle square; the two horizontal measuring devices are respectively arranged at two top angle ends of the inner arc angle square; and the two suspension wire pendants are respectively arranged at the two bottom angle ends of the inner arc angle square.
As a preferable technical scheme of the utility model, the inner arc radius of the inner arc angle square is equal to the radius of the upright post, and the inner arc length of the inner arc angle square is equal to one fourth of the perimeter of the upright post.
As a preferable technical scheme, the inner arc scale mark of the inner arc angle square horizontally penetrates through the surface of the body of the inner arc angle square in two directions.
As a preferred technical scheme of the utility model, the two side lengths of the inner arc angle square are perpendicular to each other and are equal in length, and the side length of the inner arc angle square is equal to the sum of the radius of the upright post and the length of the end part of the inner arc angle square.
As a preferred technical solution of the present invention, the leveling device is a cylindrical leveling bubble, and two of the leveling devices are arranged vertically in the axial direction.
Compared with the prior art, the utility model provides the positioning ruler for the surface of the cylinder, which has the following beneficial effects:
the method comprises the steps of finding an upright post rooted by a support according to position information data on a support map, determining the general position of the rooted upright post, determining the positioning in the height direction by utilizing a suspension wire pendant, matching an inner arc angle square with the outer diameter of the upright post, ensuring that the side length of the inner arc angle square is in the positive direction (east or south or west or north) through a zero line on an upright post body and the vertical feet of two suspension wire pendulums and a deck, leveling the whole positioning square by utilizing two horizontal measuring devices, measuring by utilizing the inner arc angle square according to the difference value of the central coordinate of the upright post and the positioning coordinate on a drawing, and determining the crossed position of a scale line and the upright post as a support positioning point according to the positioning measurement result.
