随着工业技术的发展,生产工艺流程经常改变,这就要求建筑体系具有灵活的平面和空间。大柱网的单层联合厂房通用性强、建筑面积使用率高、管理方便,它是工业建筑的发展趋势之一。该建筑体系的特点是:柱网尺寸有12×12m、12×18m、18×12m、18×18m等四种;屋盖形式为锯齿形,不另设天窗架,如图1;采用装配式预应力钢筋混凝土构件; With the development of industrial technology, the production process flow often changes, which requires that the building system has a flexible plane and space. Dalian Net’s single-storey joint factory building has strong versatility, high construction area usage and convenient management. It is one of the development trends of industrial buildings. The characteristics of the building system are: the size of column nets are 12×12m, 12×18m, 18×12m, 18×18m, etc.; the roof forms are zigzag, and no sunroof frame is installed, as shown in Fig. 1; Prestressed reinforced concrete components;
