Construction method for intelligently controlling large-space special-shaped curved surface based on BIM technology

Abstract

The invention discloses a construction method for intelligently controlling a large-space special-shaped curved surface based on a BIM technology, and relates to the technical field of BIM application, and the method is characterized by comprising the following steps: S1, carrying out the three-dimensional laser scanning of a civil engineering field main structure after construction, and obtainingthe point cloud model data of the field structure; and S2, processing and analyzing the acquired point cloud model data of the field structure, performing reverse modeling on the field structure by utilizing BIM software according to the point cloud model data, and optimizing a spatial special-shaped curved surface decoration BIM model according to a field civil engineering point cloud model. According to the invention, three-dimensional scanning is carried out on the civil engineering; buried point measurement does not need to be conducted on site manually, constructed civil engineering canbe measured efficiently with high precision, an accurate and visual construction deviation analysis result is obtained rapidly, installation and real-time adjustment are guided through lofting of thepay-off robot and on-site real-time monitoring, error accumulation is avoided, and the decoration construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of BIM application technology, more specifically, it relates to a construction method for intelligently controlling large-space special-shaped curved surfaces based on BIM technology. Background technique [0002] With the continuous development and popularization of construction engineering BIM technology and computer instrument technology, architects are pursuing the design of large-space special-shaped structures, and large-space special-shaped building structures are becoming more and more common. How to complete such difficult construction tasks with high quality and high standards is the key to the success or failure of the overall architectural effect. [0003] During the construction of the main structure of the decoration project, the embedded parts are placed according to the construction drawings, and there will inevitably be construction errors in the construction of civil engineering. The traditional meth...

Problems solved by technology

However, due to the large number of measurement points of embedded parts, it will consume a lot of manpower and material resources to re-measure and re-model or rely on measurement for material processing, and due to the accumulation of on-site operation errors, it is extremely difficult to control the accuracy of decoration construction, and the construction period is relatively long, so The traditional method is not suitable for the special-shaped decorative surface engineering
