Prestressed anchoring structure system for multi-segment pier assembly and multi-segment pier assembly construction method
The prestressed anchoring structure system comprises a bent cap, n pier column sections, a base platform, a prestressed steel strand anchoring structure assembly for connecting and anchoring the pier column sections and the base platform, and a steel bar temporary anchoring assembly composed of n + 2 steel bars, nuts and connecting sleeves. Steel bar penetrating hole channels are formed in the bent cap, the n pier column sections and the base table, and reaming sections for connecting pier column steel bars are arranged at the lower ends of the steel bar penetrating hole channels of the bent cap and the pier column sections; in an anchoring state, one end of the steel bar in the abutment serves as a fixed end to be arranged in the abutment and bonded and anchored with the abutment concrete, the other end of the steel bar extends out of the end face of the abutment, and the pier column steel bar of the nth section of pier column is connected with the pier column steel bar of the (n-1) th section of pier column through the connecting sleeve; the bent cap section reinforcing steel bar is connected with the pier column reinforcing steel bar of the nth section pier column through the connecting sleeve; the abutment inner steel bars, the pier column steel bars and the cover beam steel bars are temporarily anchored through nuts and provide pressing force, and n is larger than or equal to 2 and smaller than or equal to 10. The temporary connection structure of the system is simple; and the construction is convenient.
一种多节段桥墩拼装用预应力锚固结构体系，包括盖梁、n节墩柱节段和基台以及将其连接锚固的预应力钢绞线锚固结构组件和由n+2条钢筋、螺母和连接套筒组成的钢筋临时锚固组件；在盖梁、n节墩柱节段和基台内均设有穿钢筋孔道，盖梁、各节段墩柱穿钢筋孔道下端设有墩柱钢筋连接用扩孔段；锚固状态下，基台内钢筋一端作为固定端设于基台中与基台砼粘结锚固，另一端伸出基台端面，第n节段墩柱之墩柱钢筋通过连接套筒与第n‑1节段墩柱之墩柱钢筋连接；盖梁节段钢筋通过连接套筒与第n节段墩柱之墩柱钢筋连接；基台内钢筋、各墩柱钢筋和盖梁钢筋分别通过螺母被临时锚固并提供压紧力,上述2≤n≤10。该体系的临时连接构造结构简单；施工方便。
