Description

Technical Field

[0002] Prefabricated steel-concrete structure is one of the important directions of the development of building structure in my country. Prefabricated steel-concrete columns have the advantages of controllable product quality, green environmental protection and convenient construction. The column-to-column connection method is an important connection method in the prefabricated structural system. It directly affects the construction speed and assembly degree of the structure. Therefore, the construction method of the column-to-column splicing node should be as simple as possible, and its strength should not be lower than that of the prefabricated steel-concrete column. However, there are fewer splicing node forms for existing prefabricated steel-concrete columns, and the specific implementation methods are relatively cumbersome. Therefore, a new type of node with superior performance, convenient construction and meeting the requirements of building industrialization is needed.
