Anchoring connection structure of steel pier and bearing platform
The invention discloses an anchoring connection structure of a steel pier and a bearing platform, which comprises a pressure bearing system anchored with the bearing platform and a prestress system circumferentially distributed on the pressure bearing system corresponding to the steel pier, the pressure bearing system comprises an annular wall plate anchored in the bearing platform and a pressure bearing partition plate covering the upper end of the annular wall plate along the top surface of the bearing platform, the part, above the bearing platform, of the prestress system is welded to the steel pier wall plate and the pressure-bearing partition plate, the lower end of the prestress system is anchored in the bearing platform, and the pressure-bearing system downwards transmits force borne by the structure above the pressure-bearing partition plate to the bearing platform; according to the present invention, the structure is simple, the stress is good, the force transmission is direct, the bearing capacity is high, the large axial force, the large horizontal force and the large bending moment can be borne, the excellent crack resistance, the excellent fatigue resistance and the excellent durability are provided, the required construction space is not large and stable, the structural strength is high, the 100-year design service life requirement can be met, and the structure is suitable for the high-intensity earthquake region.
本发明公开了一种钢墩与承台的锚固连接构造，包括与承台锚固的承压系统，和对应钢墩周向分布于承压系统上的预应力系统，所述承压系统包括锚固于承台内的环形壁板，和沿承台顶面盖设于环形壁板上端的承压隔板，所述预应力系统的承台以上部分与钢墩壁板及承压隔板焊接，预应力系统的下端锚固于承台内，承压系统将承压隔板以上结构所承受的力向下传递至承台；受力好，传力直接，承载力高，可以承受较大的轴力、水平力和弯矩，具有优异的抗裂性、抗疲劳和耐久性，所需构造空间不大且稳定，结构强度高，可以满足100年的设计使用年限要求，也适用于高烈度地震区。
