Prefabricated box girder segment structure and construction method thereof
The invention discloses a prefabricated box girder segment structure which comprises a segment frame and a concrete layer, the segment frame comprises a box girder reinforcement cage and two end splice plates, the two end splice plates are welded and fixed to the two sides of the box girder reinforcement cage respectively, the end splice plates are provided with a plurality of bolt holes and a plurality of prestress tensioning holes, and the concrete layer is arranged on the concrete layer. A plurality of metal corrugated pipes are arranged in the box girder reinforcement cage, the positions of the prestress tensioning holes are matched with the positions of the metal corrugated pipes, the two ends of the metal corrugated pipes are fixed to the prestress tensioning holes of the front side end splicing plates and the prestress tensioning holes of the rear side end splicing plates respectively, the concrete layer is poured on the box girder reinforcement cage, and the end splicing plates on the two sides are exposed out of the concrete layer. During splicing, the end splice plates of the adjacent prefabricated box girder sections are spliced, bolt holes of the spliced end splice plates are aligned and fixed through bolts and nuts in a matched mode, and after the bolts are installed, splicing groove seams are filled with waterproof paint and epoxy resin.
本发明公开了一种预制箱梁节段构造，包括节段框架和混凝土层，所述节段框架包括箱梁钢筋笼和两个端头拼接板，两个端头拼接板分别焊接固定在箱梁钢筋笼两侧，所述端头拼接板设置有多个螺栓孔和多个预应力张拉孔，所述箱梁钢筋笼内配置多个金属波纹管，预应力张拉孔位置与金属波纹管相适配，金属波纹管两端部分别固定在前侧端头拼接板和后侧端头拼接板的预应力张拉孔上，所述混凝土层浇筑于箱梁钢筋笼，两侧的端头拼接板外露于混凝土层，拼接时，相邻预制箱梁节段的端头拼接板相拼接，相拼接的端头拼接板螺栓孔对齐并通过螺栓和螺帽配合固定，螺栓安装完成后，拼接槽缝处通过防水涂料和环氧树脂填充。
