Connecting structure of steel stand column and concrete bearing platform and construction method thereof
The invention provides a connecting structure of a steel stand column and a concrete bearing platform, and belongs to the technical field of bridge engineering prefabrication and assembly. The connecting structure is characterized in that on the basis of high-strength prestressed anchor bolt connection at the bottom of the steel stand column, the built-in double-layer flange plate design is adopted, and in addition, each pre-buried assembly scattered inside the bearing platform is designed into an invariable whole mechanism; the double-layer flange plate design increases the force transmissionanchoring length, and reduces column bottom stress concentration; meanwhile, due to the built-in flange connection structure, the bearing platform structure is simplified, key connection components are isolated from the outside, the durability of the key connection components is improved, and reversible operation of stand column installation can be achieved according to needs; the integral pre-buried assembly can improve the burying precision and reduce the disturbance influence generated by bearing platform concrete construction. The connecting structure is simple, convenient in construction, readily ensures the quality of component connection, and has the good popularization value.
本发明提供了一种钢立柱与混凝土承台连接构造，属于桥梁工程预制拼装技术领域。该连接结构在钢立柱底部高强预应力锚栓连接基础上，采用内置式双层法兰板设计，此外承台内各分散的预埋组件设计成机构不可变整体。该连接方式双层法兰板设计增加传力锚固长度，降低了柱底应力集中；同时内置式法兰连接构造，简化承台构造，使关键连接构件与外界隔离，提高其耐久性，并可根据需要实现立柱安装的可逆操作；整体式预埋组件可以提高埋设精度，降低承台混凝土施工产生的扰动影响。该连接构造简单、便于施工，易于保证构件连接的质量，具有较好地推广价值。
