Abstract

The invention particularly relates to an application method of BIM modeling in design and construction of a special-shaped curved surface structure body. The method comprises the steps: 1, carrying out early-stage exploration; 2, carrying out defect checking, leakage repairing and drawing optimizing on an original design drawing; 3, carrying out parameterized arithmetic unit program building; 4, carrying out parameterized generation of clamps and pipelines; 5, parameterizing and extracting large-batch three-dimensional space coordinates; and 6, carrying out subsequent application of BIM modeling. According to the application method, the application of parameterization combination of rhino and grassshapper is adopted; athree-dimensional modeling software rhino and an attached plug-in grasshopper are combined, so that comprehensive analysis and research are carried out on the application in the special-shaped curved surface structure project process; grasshopper parameterization furtherimproves the high efficiency of building design and the relevance of all professions, quantitative information in the model is quantified, and the construction management level and the overall projectquality are greatly improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for using BIM modeling in the design and construction of special-shaped curved surface structures. Background technique [0002] Snowmobile sledding is a high-speed extreme sport; the shape of its track often has the characteristics of winding and twisting, and its overall shape can be summarized as a semi-open tubular structure with three-dimensional distortion in space. According to the requirements of the full-length low temperature of the track, the interior of the track contains hyperboloid cooling pipes, pipe support fixtures and steel mesh skeletons for fixing the support fixtures. Taking the bobsleigh track for the 2020 Beijing Winter Olympics as an example, the main track has a total length of 1,935 meters and a vertical height difference of 127 meters. The average slope is 9.8%, and the maximum slope is 16%. The changeable track outline gives the building ...
