Open diagonal bracing type steel diaphragm reinforcing structure of combined small box girder bridge
The invention discloses a combined small box girder bridge opening inclined strut type steel diaphragm reinforcing structure which comprises through long components N3 at the bottoms of box girders, two inclined struts N2 between the box girders and rectangular steel plates N1 located on webs of the two adjacent box girders, and the two ends of the inclined struts N2 are connected with welding steel plates N6 located on the through long components N3 and N1 in a welded mode. The rectangular steel plate N1 is connected with two adjacent box girder webs in a bolt connection mode; a rectangular steel plate N4 is arranged at the position of a box girder bottom plate and connected with the box girder bottom plate in a bolt connection mode, the rectangular steel plate N4 and a full-length component N3 are connected in a welded mode through a leveling wedge block component N5, effective connection of the full-length component N3 and the rectangular steel plate N4 is guaranteed by adjusting the thickness of the leveling wedge block component N5, local disengaging is avoided, and the overall performance of the full-length component N3 is improved. The anti-bending and anti-shearing force transmission requirements among the small box girders are met, so that the main girders can be better stressed together; the steel members can be prefabricated in factories, construction is convenient, and the construction speed is high.
本发明公开了一种组合小箱梁桥开口斜撑式钢横隔梁加固构造，包括箱梁底部通长构件N3，箱梁之间的两根斜撑N2，以及位于相邻两箱梁腹板上的矩形钢板N1，斜撑N2两端通过焊接的方式与位于通长构件N3和N1上的焊接钢板N6连接，矩形钢板N1通过螺栓连接的方式与相邻的两箱梁腹板连接；在箱梁底板位置处，设置有矩形钢板N4通过螺栓连接的方式与箱梁底板连接，在矩形钢板N4与通长构件N3之间通过调平楔块构件N5将两者焊接连接，通过调整调平楔块构件N5的厚度，来保证通长构件N3与矩形钢板N4的有效连接，避免出现局部脱空，保证小箱梁之间抗弯抗剪的传力要求，使各主梁能更好的共同受力；钢构件可以工厂预制，方便施工，施工速度较快。
