Staggered truss structure system and node structure thereof
The invention relates to the technical field of building structures, and provides a staggered truss structure system and a node structure thereof. The staggered truss structure system comprises prefabricated reinforced concrete columns, steel trusses, steel beams and prestressed hollow slabs, wherein the prefabricated reinforced concrete columns are adopted, and the staggered truss structure system has the advantages of steel saving, good fire resistance and durability, good stress performance and high structural rigidity. According to the staggered truss structure system, nodes connected with the steel trusses are pre-buried in a prefabricated reinforced concrete columns, brackets are arranged on the prefabricated reinforced concrete columns, the prefabricated reinforced concrete columns are connected with the steel trusses in a dry operation mode on site, the steel truss structure is placed on the brackets, and then the nodes are installed, so that the construction difficulty is greatly reduced, the construction precision is easily guaranteed, the construction efficiency is improved.
本发明涉及建筑结构技术领域，提供了一种交错桁架结构体系及其节点构造。本申请提供的交错桁架结构体系，包括预制钢筋混凝土柱、钢桁架、钢梁和预应力空心板，采用预制钢筋混凝土柱，具有节约钢材，耐火性耐久性良好，受力性能好和结构刚度大的优点。预制钢筋混凝土柱中预埋了与钢桁架连接的节点，包括在预制钢筋混凝土柱上设置牛腿，现场采用干式作业的方式与钢桁架连接，将钢桁架结构放置在牛腿上再进行节点安装的施工方式，大大减轻施工难度，容易保证施工精度，提高施工效率。
