Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] refer to figure 1 , the present invention provides a method for measuring a super-high-rise elevator shaft, using the design drawings of the elevator shaft to establish a BIM model as a reference, and then performing a fitting analysis on the point cloud model formed by measuring the three-dimensional point cloud data obtained by measuring the elevator shaft, thereby obtaining Deviation data to complete the measurement of the elevator shaft. In the process of measurement, there is no need for operators to hang wires at the elevator shaft, which can effectively ensure the safety of operators, and the processes of data collection, processing, modeling, and fitting analysis in the measurement method of the present invention are all Through the software, the calculation speed is fast, the measurement is efficient and accurate, and a new met...

Abstract

The invention relates to a super-high-rise lift well measuring method, which comprises the following steps: after finishing construction of a lift well, carrying out division of scanning sites; collecting coordinates of all position points corresponding to the scanning sites on the lift well at the corresponding scanning sites formed after division, and summarizing the coordinates to form three-dimensional point cloud data; according to the three-dimensional point cloud data, establishing a point cloud model of the lift well; establishing a BIM model of the lift well according to design paperof the lift well; and carrying out fitting analysis on the point cloud model and the BIM model, and obtaining deviation data of the point cloud model and the BIM model, thereby finishing measurement of the lift well. The measuring method is high in measurement precision; and compared with an existing plumb line method, the measuring method can effectively ensure safety of operators, and is high inefficiency of the measurement work.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for measuring a super high-rise elevator shaft. Background technique [0002] With more and more super high-rise buildings, especially super high-rise buildings over 500 meters in the construction process, the elevator shaft is generally placed inside the core tube. Elevators in super high-rise buildings are generally high-speed elevators, and the requirements for the control of the size deviation of the elevator shaft are particularly high. Effective measurement methods must be used to ensure the accuracy of the size measurement of the elevator shaft. [0003] At present, in the process of measuring the elevator shaft with the traditional hanging wire pendant measurement method, because the height of the elevator shaft is too high, there is no effective measurement space around the elevator shaft, and this measurement method cannot effectively carry out accurate mea...
