钢管混凝土结构体系的整体性能受到节点连接的直接影响和决定,钢管混凝土节点连接的设计起着非常关键的作用。为解决现有钢管混凝土结构连接方法存在的问题,提出了一种新型的连接方法,钢管混凝土灌浆套筒连接方法,并详细地说明了灌浆套筒连接装置的构成、施工方法和应用的范围。此灌浆套筒连接装置具有施工简单、承载力高等特点,并且传力明确、安全可靠,为钢管混凝土的推广应用提供了理论依据。
The overall performance of CFST system is directly affected by the connection of nodes and the decision is made. The design of CFST joints plays a crucial role. In order to solve the existing problems in the connection method of CFST structure, a new connection method and connection method of CFST grouting sleeve are proposed. The construction, construction method and application range of the grouting sleeve connection device are described in detail. The grouting sleeve connecting device has the advantages of simple construction and high bearing capacity, and has the advantages of clear force transmission, safety and reliability, and provides theoretical basis for the popularization and application of concrete filled steel tubular.
