预应力拉索索夹节点类型及应用现状

Type and application of cable clamp joints of prestressed cable

建筑索结构在大跨空间结构领域应用广泛,索夹节点是索结构中连接索体和相连构件的重要节点,保证了拉索与钢结构主体协同工作。随着新材料的产生和制作工艺的不断优化,新型索夹节点不断的应用到建筑索结构中。结合国内外工程实例和预应力拉索索夹节点的研究现状,从预应力拉索索夹节点的构造、类型、选材与应用的现状方面进行了论述。

Cable structure is widely used in the field of long-span spatial structure.Cable clamp node is an important node connecting cable body and connecting member in cable structure,which ensures the cooperation between cable and steel structure.With the production of new materials and the continuous optimization of manufacturing technology,new cable clamp joints are constantly applied to the cable structure of buildings.This paper summarizes the type,material selection and application status of prestressed cable clamp joints in combination with domestic and foreign practical engineering and research status of prestressed cable clamp joints.
