【摘要】 平法规定,柱平法施工图的表示有截面注写方式和列表注写方式两种。截面注写方式系在柱平面布置图的柱截面上,分别在同一编号的柱中选择一个截面按照一定的比例放大,同时注写截面尺寸和具体配筋数值的方式来表达柱平法施工图。实际工程图纸中放大的柱截面大都直接表示在定位轴线上。本文便是针对这种截面法表示的框架柱,利用其制图规则以及表示特点,研究出一种计算机能够自动识别并且生成柱构件三维模型的算法并将其应用到三维钢筋、工程量算量软件中。经过对大量工程图纸的应用测试以及用户对实际工程的应用检验,能够快速进行图纸识别、三维建模以及相关的BIM应用。更多还原

【Abstract】 According to the plane-method, methods for marking the column leveling construction drawing include the list drawing method and the section drawing method, which refers to the fact that a cross section is respectively selected among the columns with the same serial number, and enlarged on the basis of a certain proportion, meanwhile the size of the cross section and the number of the specific reinforcement are noted. In practical engineering, most of the column cross sections which are amplified in the engineering drawings are directly marked on the positioning axis. This paper, based on cartographic rules and characteristics of the section drawing method, presents an algorithm for the automatic recognition and generation of 3D models of column components, and applies it in the three dimensional steel bar software and engineering quantity calculation software. By a large number of testing, for engineering drawings and the actual project application, the algorithm can quickly identify the drawings, model 3D modeling, and find its application in BIM as well.更多还原
