Abstract: Based on the analysis and summarizing of various support and hanger standards and styles，the hierarchy topological model of support and hanger is presented and the topological constraint model of support and hanger based on duality smart point model is put forward.The topological constraint model can resolve the nested smart group，which is brought on the multi-constraint and hierarchy structure of support and hanger.To resolve two key problems，that are variety of design standards and tight cooperativeness with other system，the modeling method based on the topological constraint template is presented to elaborate on the design standards of support and hanger.Therefore，the design of support and hanger is transformed into the solution of multi-constraint by the modeling method based on the topological constraint template.

摘要： 基于支吊架标准和形式的分析，抽象出了支吊架拓扑结构的层次模型，提出了基于对偶智能点的支吊架拓扑约束模型，解决了支吊架拓扑关系多元性和层次性导致的智能组嵌套问题。使用拓扑约束模板表达支吊架设计标准，将支吊架设计转化为多元约束求解，解决了支吊架设计中设计标准的多样性和专业间的紧密协同性两个关键性问题。
