由中国建筑科学研究院结构所和常州建筑构件厂网架分厂共同开发、研制的一种新型预制装配式网架结构最近试验成功,该网架结构与普通螺栓球网架相比具有取材容易、造价低、节点构造简单,适用于24m 跨度以下中、小型网架屋盖,该网架结构可以在工厂预制成单个锥体,现场只需拼装这些单锥体并将下弦杆连接即可,试验进行了由六个单 A new type of prefabricated grid structure jointly developed and researched by the China Institute of Building Research and the Changzhou Building Component Factory grid structure plant has been successfully tested. The structure of the grid structure is easier to obtain than ordinary bolt ball grids. Low cost, simple node construction, suitable for small and medium grid roofs below 24m span. The grid structure can be prefabricated into a single cone at the factory. Only the single cones can be assembled at the site and the lower chord can be connected. The experiment was conducted by six singles
