Segmented box girder structure and construction method thereof
The invention discloses a segmental box girder structure and a construction method thereof, and belongs to the technical field of bridge engineering. The segmental box girder structure comprises a girder body, butt joint ends and butt joint embedded parts. The beam body is a U-shaped box beam section with an opening in the top, and an embedded butt joint rib is arranged in the beam body; the two ends of the beam body are each provided with a butt joint end, the beam body and the butt joint ends are poured and condensed into an integral structure, pre-embedded butt joint ribs can be additionally arranged at the joints between the beam bodies, larger connecting stress is provided, and butt joint embedded parts are arranged in the end faces of the prefabricated and assembled beam bodies of the sections, so that the connecting strength is improved. Steel structure connecting joints and joints are poured into a whole, the strength is improved by welding butt joint embedded parts, reserved clamping grooves of the joints form transverse stress clamping blocks, the pulling resistance of the whole structure of the segment prefabricated assembled small box girder bridge can be enhanced, and concrete solidified in the reserved clamping grooves and positioning holes is not prone to falling off. The steel bar can serve as a longitudinal steel bar after joint pouring is completed, and the ultimate bearing capacity of the joint position is improved.
本发明公开了桥梁工程技术领域的一种节段式箱梁结构及其施工方法，包括梁体、对接端头、对接预埋件；所述梁体为顶部开口的U形箱梁节段，所述梁体内部设置了预埋对接筋；所述梁体的两端各设置了一个对接端头，所述梁体与对接端头浇筑凝结为整体结构，能够在梁体之间的接缝处增加预埋对接筋，提供更大的连接应力，并且在节段的预制拼装的梁体端面内设置对接预埋件，将钢结构连接节点与接缝浇筑为整体，还通过焊接对接预埋件增加强度，并且接缝的预留卡槽形成横向受力卡块，可加强节段预制拼装小箱梁桥梁整体结构抗拉扯力，预留卡槽和定位孔凝固的混凝土，可以在接缝浇筑完成后可充当纵向钢筋，提高接缝位置处的极限承载力。
