Inclined bracket stay cable anchoring combined structure and construction method thereof
The invention belongs to the field of bridge engineering, and particularly relates to an inclined bracket stay cable anchoring composite structure and a construction method thereof, which are mainly used for short tower cable-stayed reinforcement of a PSC continuous box girder bridge. The structure comprises a concrete box girder, a prestress finish rolling twisted steel, a bracket support and a stay cable anchoring device. Tie bar through holes are punched in an old bridge concrete box girder, prestressed bars penetrate through the concrete box girder, a bracket support stay cable anchoring combined structure can be erected on the outer side of a box girder web, and stable connection of stay cable anchoring positions of a short tower cable-stayed system reinforcing PSC continuous box girder bridge and rapid erection of a construction platform are achieved. The inclined bracket supporting component capable of being welded and assembled is utilized, the stay cable anchor pipe is installed at the inclined web member, the load borne by the main beam can be transmitted to the stay cable, and therefore the load borne by the main beam is effectively relieved.
本发明属于桥梁工程领域，具体涉及一种倾斜牛腿斜拉索锚固组合结构及其施工方法，主要用于矮塔斜拉加固PSC连续箱梁桥。该结构包括混凝土箱梁，预应力精轧螺纹钢筋，牛腿支架，斜拉索锚固装置。通过在旧桥混凝土箱梁中打穿拉筋贯穿孔，将预应力筋贯通在混凝土箱梁内，可在箱梁腹板外侧架设牛腿支架斜拉索锚固组合结构，实现了矮塔斜拉体系加固PSC连续箱梁桥的斜拉索锚固处的稳定连接和快速架设施工平台。利用可焊接拼装的倾斜式牛腿支撑构件，将斜拉索锚管安装在斜向腹杆处，可将主梁承受的荷载传递至拉索处，从而有效缓解主梁承受的荷载。
