Abstract

The invention provides a rapid survey and setting-out method for high-rise buildings. The rapid survey and setting-out method comprises the following steps: erecting a GPS-RTK (Global Positioning System-Real-time Kinematic) base station on an empty place of a construction site; erecting a survey robot at a middle position of a construction floor; setting at least four control points at the periphery of the construction floor by utilizing a GPS-RTK mobile station; transmitting a coordinate of each control point to the survey robot to finish oriented work of a free station; finally, obtaining a structure position of a floor needing to be subjected to setting-out by utilizing a BIM (Building Information Modeling) technology; finishing the setting-out of a main control axis of the floor and a formwork erecting line of a structure through the survey robot. The rapid survey and setting-out method is simple to operate and convenient to use; automatic, paperless and visualized three-dimensional setting-out of construction buildings is really realized, and the setting-out efficiency and setting-out precision of the main control axis of each floor and the formwork erecting line of the structure are improved; the accuracy of a setting-out result is ensured from the source; meanwhile, the safety problem of falling objects is also avoided.

Description

technical field

[0001] The invention relates to the technical field of building surveying and mapping, in particular to a method for rapid measurement and setting out of high-rise buildings. Background technique

[0002] With the acceleration of urbanization, there are more and more high-rise and super high-rise buildings. In the process of setting out the main control axis of the floor and the vertical mold line of the structure, it is still not possible to fully realize the automatic, paperless and visualized three-dimensional setting out. .

[0003] In the prior art CN105575249A, the currently commonly used stakeout method is as follows: four main control axis points are measured and set at the four corners of the first floor or the bottom floor, and holes are reserved on each floor at their corresponding positions, and the laser plummet is used to project points upward. Function and total station (or theodolite) axis measurement function, respectively lead the main cont...
