BIM-based parameterized building facade design method, facade component and skin model

Abstract

The invention provides a BIM (Building Information Modeling)-based parameterized building facade design method, a facade component and a skin model. According to the design method, Rhino and Grasshopper software are applied on the basis of BIM, and a pixelated grid 2D normal projection 3D curved surface space grating geometric subdivision method is adopted; the method specifically comprises the six steps of extracting pixel grid points and 2D grid intersecting lines, constructing a building facade texture of an overall space body block, reconstructing a body block model of the overall space body block, further reconstructing a deepening model of the overall space body block, reconstructing a parameterized facade texture skin component and reconstructing a building skin model. The facade component is obtained through the design method and comprises a component body, the component body is formed by assembling a pair of triangular prism-shaped grids and a connecting piece arranged between the pair of triangular prism-shaped grids, the connecting piece comprises a cushion block and a connecting shaft embedded in a through hole in the cushion block, and the cushion block is embedded between the pair of triangular prism-shaped grids; sealing plates are arranged at the upper and lower ends of the component body. The method can guide the mass production of novel building industrialization.

Description

technical field [0001] The invention belongs to the technical field of building facade design, and in particular relates to a BIM-based parametric building facade design method, a facade component, and a skin model. Background technique [0002] In the field of architectural design, designers usually use the parametric software Rhino and Grasshopper of architectural digital information technology (BIM) to model and design the conceptual scheme of parametric buildings, and generally use large-scale spaces directly in industrial construction Components to directly express the conceptual effect of the architectural plan and assemble the skin model of the building facade texture, and then carry out the construction design and construction in the later stage of the project. The existing parametric building facade texture is usually composed of a double-layer skin structure in industrial construction. The skin of the external pattern effect part is composed of parametric large-sca...

Problems solved by technology

[0003] Aiming at the series of problems existing in the current prior art, the present invention provides a BIM-based parametric building facade design method and facade components and skin models. Starting from the facade texture effect in the paper, according to a picture of a rendering, the spatial structure system of the parametric building facade texture skin in industrial construction is complex, the shape of each component of the texture skin is freely distorted and the size is huge, the details and the overall accuracy Insufficient, affected by the material, its self-weight load is huge, and it is impossible to carry out standardized mass production in the factory. At the same time, it can ensure that the overall effect of the building facade texture is to carry out spatial rotation and gradient along the curves and surfaces.
