Steel-encased-ultra-high-performance concrete reinforcing method for box girder
The invention discloses a steel-encased-ultra-high performance concrete reinforcing method for a box girder. The method comprises the following steps of setting out the positions of bolts and embedded steel bars on the box girder, and drilling at the position of the box girder; mounting and maintaining the embedded steel bars, and embedding steel bar hooks along the longitudinal direction of the bridge; bottom plate stirrups and web stirrups being installed and bound with the embedded steel bars; the positions of the studs being lofted, and the studs being welded to the bottom steel plate and the side steel plates; the bottom steel plate and the side steel plates being fixed to the box girder through bolts, and the bottom steel plate and the side steel plates being welded through fillet welds; and ultra-high performance concrete being poured and cured. The method steel-encased ultra-high performance concrete of the box girder is reinforced, the steel plate-ultra-high performance concrete can effectively improve section rigidity of the original structure, the bearing capacity of the structure is greatly improved, the size of the reinforced section of the structure is small, and reinforcing efficiency is high. According to the steel-ultra-high performance concrete reinforcing design, common load-bearing steel bars and prestressed steel strands are not configured, and the site construction process is simple.
本发明公开了一种箱梁的外包钢‑超高性能混凝土加固方法，包括以下步骤：箱梁上螺栓、植入钢筋位置放样，并在箱梁所在位置钻孔；安装植入钢筋并养护，沿桥梁纵向植入钢筋弯钩；安装底板箍筋和腹板箍筋，并与植入钢筋绑扎；栓钉位置放样，将栓钉焊接于底钢板和侧钢板；将底钢板和侧钢板与采用螺栓固定于箱梁，并将底钢板和侧钢板采用角焊缝焊接；浇筑超高性能混凝土并养护。箱梁的外包钢‑超高性能混凝土加固，钢板‑超高混凝土能有效提高原结构的截面刚度，大幅提高结构承载能力，且结构加固截面尺寸小，加固效率高。钢‑超高性能混凝土加固设计不配置普通受力钢筋和预应力钢绞线，现场施工工艺简单。
