建筑表皮的拓扑剖分

当今随着建筑技术的进步,建筑表皮逐渐朝着跨度更大和覆盖的空间更广的方向转变。在这种趋势影响下,大面积的表皮必须剖分成小面积的单元组合形式,这些剖分形式包括三角形、四边形、六边形、混合剖分以及加细剖分,它们使表皮形态突破了材料尺寸对表皮构成的束缚,同时也使得建筑表皮获得了良好的尺度。更为重要的是这些表皮的剖分形式蕴含着拓扑学的剖分不变性的原理,通过对这些拓扑原理的认识,可以使人们对表皮的构成和设计进行多方位和深层次的把握。

Topology of Architectural Skin

At present, architectural skin is transforming to greater span and wider space gradually with the progress of architectural technology. Under this background, large area skin must be subdivided to small unit, including triangulation, quadrangle, hexagon, mixed and refined subdivision, which cause the skin form break through the tie of material size, simultaneously make the skin obtain favorable size. It is more important that these kinds of subdivision implicit the principle of topological subdivision invariability. And through understanding these topological principles, people may grasp skin construction and design from multiaspect and deep level.
