Fabricated waffle bridge deck slab combined box girder structure and construction method thereof
The invention discloses a fabricated waffle bridge deck slab combined box girder structure and a construction method thereof. The fabricated waffle bridge deck slab combined box girder structure comprises a steel box girder, a UHPC waffle bridge deck slab and a shear nail group, the shear nail group is welded to the upper surface of a top plate of the steel box girder, and the prefabricated UHPC waffle bridge deck slab is connected with the steel box girder through the shear nail group; a transverse joint and a longitudinal joint are reserved between every two adjacent UHPC waffle bridge panels located at the top of the steel box girder, and UHPC concrete is poured at the transverse joints and the longitudinal joints. Compared with a traditional prestressed concrete box girder, the prestressed concrete box girder bridge has the advantages that high compressive property and tensile property of UHPC high-strength concrete are fully utilized, the girder height and self weight are reduced, prefabricated assembly can be achieved, the construction period is short, the bridge economy is high, and some technical defects of the traditional prestressed concrete box girder bridge are overcome.
本发明公开一种装配式华夫桥面板组合箱梁结构及其施工方法，包括钢箱梁、UHPC华夫桥面板和剪力钉群，钢箱梁的顶板上表面焊接有剪力钉群，预制的UHPC华夫桥面板通过剪力钉群与钢箱梁相连接，位于钢箱梁顶部的相邻两块UHPC华夫桥面板之间预留有横向接缝和纵向接缝，在横向接缝和纵向接缝处浇筑有UHPC混凝土。本发明与传统的预应力混凝土箱梁相比，充分利用了UHPC高强混凝土良好的抗压性能和抗拉性能，减小了梁高和自重，可预制化拼装，施工工期短，桥梁经济性高，克服了传统预应力混凝土箱梁桥的把一些技术不足问题。
