空间网格结构装配式节点分类与发展需求
Classification and development demand of assembled connectors in space grid structures
摘要
Abstract
The assembly joints development is the key to breakthrough.Domestic related research started late,and more innovation is needed.Various typical and newly developed assembly nodes were introduced,and their structural features and existing classification concepts were analyzed in detail.Then a more perfect and practical classification system was formed.Starting from the functional characteristics and market demand of the connector,it was put forward that the assembly connectors in the space grid structure should meet the five requirements of structure suitability,geometric adaptability,error tolerance,appearance effect and comprehensive economy.Based on the new demand standards,in order to emphasize the importance of structural composition in the new connector scheme,the comprehensive performance and generalization degree of existing nodes are analyzed by classes,and the qualitative evaluation of various typical connectors is given.Through the comparison of the evaluation results and the actual assembly development level of the space grid structure,it is proved that the performance requirements of the new assembly type joints are reasonable.The development status of assembly connectors in grid structure is summarized,and the new changes and new trends of them are prospected.关键词
