Parametric modeling design method for fabricated building

Abstract

The invention provides a parametric modeling design method for a fabricated building, which comprises the following steps of: extracting parameters: splitting each component from a CAD structure construction drawing of the building, representing each different component with different parameters, and extracting parameter information of each component; inputting parameters: storing the parameter information of each component into a database, and inputting the parameter information into UG software to form a three-dimensional model of each component; assembling collision: correspondingly assembling three-dimensional models of a plurality of adjacent components in UG software, and carrying out collision detection and collision adjustment on the components; wherein the three-dimensional modelof the qualified standard component is converted into a two-dimensional drawing; a plurality of standard components are used for jointly forming the fabricated building. By using the method disclosedby the invention, the structure construction drawing of the house can be efficiently split into a plurality of standard components, the two-dimensional drawing of each standard component can be accurately given out in detail, and the material list for production and manufacturing can be accurately calculated as soon as possible.

Description

technical field [0001] The invention belongs to the field of prefabricated building design, in particular to a parametric modeling and design method for prefabricated buildings. Background technique [0002] With the successive introduction of various policies by the country, the emphasis on and vigorous promotion of housing industrialization and prefabricated buildings has made prefabricated buildings usher in a major development opportunity, and the design, standard and standardized production, construction and other links of prefabricated buildings are in the Energy saving, environmental protection and high efficiency have also put forward their own needs. At present, the design thinking of prefabricated buildings still generally stays on the traditional two-dimensional graphic design, and the two-dimensional drawing software such as AutoCAD and Tianzheng is used for in-depth design. Even if a small number of designers adopt digital 3D design, although they can achieve t...

AI Technical Summary

Problems solved by technology

For the design of many standard components, rely on the experience and brainpower of senior designers to figure out one by one, split them into standard components, which is obviously not conducive to improving work efficiency

Generally speaking, because the structural drawing corresponds to a wide variety and a large number of various assembled components, therefore: ①The workload of drawing is heavy and the workload is repeated

②The quality of drawings is not uniform; the quality of drawings given by different designers has its own merits, which is not conducive to the unification of drawing standards

③The workload of collision detection is also heavy, and there is a lot of repetitive workload

④ It is a complicated task to give the BOM table (the bill of materials for standard components used in construction) in the traditional method

Although the parametric modeling method appears in the patent, the patent does not involve the process of giving the two-dimensional diagram of each component of the house and calculating the BOM list at all.
