BIM method applicable to positioning specially-shaped steel-concrete structural component

Abstract

The invention discloses a BIM method applicable to positioning a specially-shaped steel-concrete structural component. The BIM method comprises the following steps of: (1), drawing a three-dimensional stereogram of the component according to a design drawing of a complex specially-shaped structural steel-concrete component; (2), according to the structural performance of the component and a height axis as the direction, performing equidistant or non-equidistant virtual segmentation so as to obtain continuous virtual sections, which are vertical to the component, and numbering the virtual sections in sequence; (3), deriving various section graphs in a CAD format from a revit three-dimensional stereogram, obtaining a common point (0,0,0), labelling three-dimensional coordinates (X,Y,Z) of various ports of the sections, and taking a key section in the design drawing as a re-check section; and (4), guiding field construction, and re-checking the key section in time, wherein the next process only can be constructed after checking is qualified till construction of the specially-shaped component is completed. According to the BIM method disclosed by the invention, the problems of relatively high positioning difficulty and relatively low precision in the existing complex specially-shaped component can be solved; the field construction is guided; therefore, the engineering construction level is improved; and the precision is ensured.

Description

technical field [0001] The invention provides a BIM method applied to the positioning of special-shaped steel-concrete structural members. Background technique [0002] like figure 1 Shown: Hyperboloid non-conventional components for special-shaped distorted shapes, figure 1 Its three-dimensional schematic diagram, Figure 2 is a schematic diagram of component cutting. The traditional design process is based on the working mode of two-dimensional drawings. When the three-dimensional model designed by the architect is due to complex buildings such as special-shaped surfaces, it is impossible to draw accurate architectural design and construction. The map guides the on-site positioning and construction, resulting in the incomplete transmission of information at each stage. Contents of the invention [0003] The purpose of this invention is to propose a BIM method applied to the positioning of special-shaped steel-concrete structural components, to solve the current problem ...
