Problems solved by technology

[0002] At present, when setting out the square column of the longitude and latitude grid, it is only applicable to the working condition of the known orthogonal axis. Only when the weft line at the intersection of the longitude and latitude axes is tangent can the sideline of the square column be released, and the measurement workload is large, and the setting time is long.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] A method for quick setting out of square columns of warp and latitude grids, such as figure 1 shown, including steps:

[0020] S1, according to the positioning coordinates of the building design drawings, determine the coordinates of intersections A and C of the minimum radius latitude line and the maximum radius latitude line respectively with the meridian where the center point B of the square column is located;

[0021] S2. According to the coordinates of A and C, use the total station to measure and mark A and C on the construction site, and draw the longitude AC;

[0022] S3. According to the distance between A or C and B in the building design drawings, start from point A or C, measure and mark B along the meridian AC;

[0023] S4. Make a straight line segment B1B2 passing through B and perpendicular to the meridian AC on the construction...

Abstract

The invention discloses a rapid paying-off method for a warp and weft axis net square column. The method comprises the steps that coordinates of intersection points A and C of the minimum radius weftand the warp where the square column center point B is positioned and the maximum radius weft and the warp where the square column center point B is positioned are determined according to positioningcoordinates of a building design drawing; according to the coordinates of A and C, A and C are measured and marked on a construction site through a total station, and the warp AC is made; according tothe distance between A or C and B in the building design drawing, B is measured and marked along the warp AC with the point A or C as the starting point; a straight line segment B1B2 which passes through B and is perpendicular to the warp AC is made on the construction site, and the straight line segment B1B2 coincides with the tangent line of the weft where B is positioned; and square column side lines are paid off according to the size relation between the four side lines of the square column and the tangent lines of the warp where B is positioned and the weft where B is positioned. According to the rapid paying-off method, the paying-off efficiency is improved, and the paying-off cost is reduced.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a method for quickly setting out a square column of a grid of warp and latitude grids. Background technique [0002] At present, when setting out the square column of the longitude and latitude grid, it is only applicable to the working condition of the known orthogonal axis. Only when the parallel line at the intersection of the longitude and latitude axes is tangent can the sideline of the square column be released, and the measurement workload is large, and the setting time is long. . Contents of the invention [0003] The object of the present invention is to provide a method for quickly setting out wires of square columns of warp and latitude grids, which improves the efficiency of the wires and reduces the cost of the wires. [0004] The technical scheme adopted in the present invention is: [0005] A method for quickly setting out square columns of a gr...
