Transverse partition plate for orthotropic plate steel bridge and manufacturing method thereof
According to the diaphragm plate for the orthotropic plate steel bridge and the manufacturing method of the diaphragm plate, the rib passing holes are formed in the connecting positions of the stiffening ribs of the diaphragm plate, it is guaranteed that the stiffening ribs continuously pass through the diaphragm plate, and the lower portions of the rib passing holes are continuously welded to the stiffening rib webs. The out-of-plane bending of the diaphragm plate caused by the bending of a bridge floor second system is improved, and the out-of-plane stress level of the rib passing hole edge of the diaphragm plate is reduced; by changing the connecting mode of the longitudinal stiffening ribs and the transverse partition plates, improving the manufacturing process of the connecting positions and applying continuous welding seams along the lower portions of rib passing holes, assembling and welding are facilitated, the manufacturing process is improved, and the manufacturing quality of the longitudinal ribs and the top plate, the manufacturing quality of the longitudinal ribs and the transverse partition plates and the manufacturing quality of the transverse partition plates and the top plate are improved. And the anti-fatigue performance of the connection of the stiffening ribs and the diaphragm plate is further improved.
本发明提供一种用于正交异性板钢桥的横隔板及其制造方法，在横隔板加劲肋连接处设置过肋孔，保证加劲肋连续通过横隔板，且过肋孔下部与加劲肋腹板连续焊接，本发明通过优化钢桥面纵向加劲肋与横隔板的连接设计，改善桥面第二体系弯曲引起的横隔板面外弯曲，降低横隔板过肋孔边缘的面外应力水平；通过改变纵向加劲肋和横隔板的连接方式，改善连接处的制造工艺，沿过肋孔下部施加连续焊缝，方便了组拼和焊接，改善了制造工艺，有利于提升纵肋与顶板、纵肋与横隔板、横隔板与顶板共三处制造品质，以及进一步提升加劲肋与横隔板连接的抗疲劳性能。
