Problems solved by technology

[0003] The purpose of the present invention is to realize a steel structure curtain wall positioning and installation correction method based on BIM three-dimensional laser scanning. This method can design the curtain wall unit size in the BIM software and perform simulated installation to eliminate possible inaccurate positioning during the installation process. Problems such as collision between curtain walls make the curtain wall installation process more refined

Abstract

The invention discloses a steel structure curtain wall positioning and mounting deviation rectifying method based on BIM three-dimensional laser scanning. The method comprises the steps of collectingfield data of a civil structure, and determining three-dimensional coordinates of an original point of the civil structure; guiding the collected field data into BIM software to build a three-dimensional model of the civil structure; designing a model of a single curtain wall unit in the BIM software; simulating mounting of the curtain wall on the three-dimensional model, and judging whether collision exists between the adjacent curtain wall units; generating coordinates of each curtain wall unit, mapping the coordinates on the civil structure, and according to the coordinates of each curtainwall unit, mounting a curtain wall on the civil structure; S600, collecting the field data of the civil structure with the curtain wall again, guiding the data into the BIM software to be compared with the three-dimensional model of the civil structure with the curtain wall, screening out the curtain wall units with mounting which does not fit the rule, and performing remounting. The mounting precision of the curtain wall is greatly improved, and irrationality of curtain wall design and mounting positions can be avoided.

Description

technical field [0001] The invention belongs to the field of curtain wall installation, in particular to a method for positioning and installing a steel structure curtain wall based on BIM three-dimensional laser scanning. Background technique [0002] In the existing steel structure curtain wall positioning and installation methods, before installing the curtain wall, most of them use manual measurement to perform installation and positioning on the surface of the building. Some curtain wall positioning and installation methods also use a level and a total station for auxiliary measurement and positioning. And because modern architecture has higher and higher requirements on the overall appearance of the building, a large number of dense curtain wall layouts are often used, and some curtain walls must be combined with the structure of the building to present certain artistic shapes with changes in shape. This makes it difficult for the above-mentioned traditional and old cu...
