Top-mounted stiffening plate stud connection combined box girder structure for prefabricated construction and construction method of top-mounted stiffening plate stud connection combined box girder structure
The invention belongs to the technical field of bridge construction, and particularly relates to an upper stiffening plate stud connection combined box girder structure for prefabricated construction and a construction method. The structure comprises a box girder top plate, a plurality of longitudinal stiffening plates are arranged on the upper surface of the box girder top plate in parallel at equal intervals in the longitudinal direction, a plurality of transverse stiffening plates are vertically arranged between the longitudinal stiffening plates, and prefabricated concrete slabs are arranged in the areas between the longitudinal stiffening plates and the transverse stiffening plates. Cast-in-place joints are arranged at the joints of the prefabricated concrete planks and the longitudinal stiffening plates and the transverse stiffening plates, a plurality of prefabricated concrete plank holes are formed in the middles of the prefabricated concrete planks, a pavement layer is arranged above the prefabricated concrete planks, and a combined box girder is fixedly arranged on the lower surface of the box girder top plate. The upper stiffening plates are adopted to replace traditional longitudinal and transverse stiffening ribs, and the prefabricated concrete plates are arranged in the middles of the stiffening plates to improve the overall flexural rigidity and torsional rigidity of the structure; the construction speed of the structure can be increased, welding of complex stiffening rib structures is reduced, and the overall stress performance of the structure is improved.
本发明属于桥梁施工建造技术领域，特别涉及一种装配化施工的上置加劲板栓钉连接组合箱梁结构及施工方法。该结构包括箱梁顶板，箱梁顶板上表面沿纵向等间距平行设有多个纵向加劲板，纵向加劲板之间垂直设有多个横向加劲板，纵向加劲板和横向加劲板之间的区域内设有预制混凝土板，预制混凝土板与纵向加劲板和横向加劲板连接处设有现浇接缝，预制混凝土板中间设有多个预制混凝土板孔洞，预制混凝土板上方设有铺装层，箱梁顶板下表面固定设有组合箱梁。本发明采用上置式加劲板代替传统的纵横向加劲肋，在加劲板中间设置预制混凝土板来提高结构的整体抗弯刚度和抗扭刚度；有助于提高结构施工速度，减少焊接复杂的加劲肋结构，提高结构的整体受力性能。
