application method and system of a BIM adaptive model in special-shaped curtain wall construction

Abstract

The invention discloses an application method and system of a BIM self-adaptive model in special-shaped curtain wall construction. The method comprises the following steps: step S1, establishing a volume model of a support system according to a transverse and vertical elevation map of a design drawing, a curtain wall form, a size and related data, and constructing a self-adaptive family model of acorresponding curtain wall component by referring to the design drawing; Step S2, analyzing three-dimensional model data, reasonably cutting the surface of the volume model of the support system according to the positioning of a curtain wall framework, dividing grids, opening node options of a surface representation form, and sequentially matching the self-adaptive model at the nodes to enable the self-adaptive model to be self-adaptive to a special-shaped surface structure form of the self-adaptive model; And S3, after the self-adaptive family model is matched with the surface form of the supporting system, obtaining a component model in a specific shape, extracting through the self-adaptive family model to obtain corresponding specification data, modeling through the obtained data, anddrawing.

Description

technical field [0001] The invention relates to the technical field of building curtain walls, in particular to an application method and system of a BIM self-adaptive model in the construction of special-shaped curtain walls. Background technique [0002] A building curtain wall is a non-load-bearing exterior wall enclosure of a building, usually consisting of a panel (glass, metal plate, stone plate, ceramic plate, etc.) and a supporting structure behind it (aluminum beams and columns, steel structures, glass ribs, etc.). The special-shaped building curtain wall should first be a building curtain wall, which has all the functions of the curtain wall; secondly, the panel and structure produce various special-shaped changes according to the requirements of the architectural shape, and achieve a certain architectural artistic effect. Special-shaped curtain walls include curved curtain walls and arc curtain walls. Curved curtain walls generally refer to complex curtain walls w...

Problems solved by technology

[0007] In order to overcome the deficiencies in the prior art above, the purpose of the present invention is to provide a method and system for applying BIM self-adaptive model in the construction of special-shaped curtain walls, so as to solve the problem that the drawing representation is not intuitive enough due to the complex shape in the construction process of traditional special-shaped curtain walls. , Some arc-shaped components or structures with an angle difference from the building plane are difficult to express clearly only by the construction plan. The actual construction needs to be measured on-site after the completion of the building structure or steel structure and other support systems before organizing the construction of difficult problems such as material cutting.
