Novel orthotropic steel bridge deck without arc-shaped notch and manufacturing method of orthotropic steel bridge deck
The invention discloses a novel orthotropic steel bridge deck without an arc-shaped notch and a manufacturing method of the orthotropic steel bridge deck. The novel orthotropic steel bridge deck comprises a panel, U-shaped longitudinal ribs, a transverse partition plate and an inner partition plate, the panel is an upper flange shared by the U-shaped longitudinal ribs and the transverse partitionplate, a UHPC layer and an asphalt wearing layer are sequentially laid on the surface of the panel from bottom to top, reinforcing steel bars and a reinforcing steel bar net are arranged in the UHPC layer, the U-shaped longitudinal rib is welded with the bottom surface of the panel to form a groove-shaped longitudinal rib abdominal cavity, the transverse partition plate is perpendicular to the U-shaped longitudinal rib and is welded with the bottom surface of the panel, a notch for the U-shaped longitudinal rib to penetrate through is formed in the transverse partition plate, and the inner partition plate is welded in the longitudinal rib abdominal cavity and is positioned in the same plane with the transverse partition plate, the inner partition plate is matched with the inner contour ofthe cross section of the U-shaped longitudinal rib, the thickness of the inner partition plate is consistent with that of the transverse partition plate. According to the method, the stress response and deflection of the orthotropic steel bridge deck structure details can be reduced under the action of wheel loads, the fatigue resistance of the structure details is improved, the orthotropic steelbridge deck is prevented from cracking, and damage to steel bridge deck pavement can be avoided.
本发明公开了一种新型免弧形切口的正交异性钢桥面板及其制造方法，包括面板、U形纵肋、横隔板和内隔板，面板是U形纵肋和横隔板共同的上翼缘，面板的表面由下至上依次铺设有UHPC层和沥青磨耗层，UHPC层中设有钢筋条和钢筋网，U形纵肋与面板的底面焊接形成槽状的纵肋腹腔，横隔板垂直U形纵肋且与面板的底面焊接，横隔板上设有供U形纵肋穿过的切口，内隔板焊接于纵肋腹腔内且与横隔板处于同一平面内，内隔板的形状与U形纵肋横截面的内轮廓相适配，内隔板的厚度与横隔板一致。本发明能降低轮载作用下，正交异性钢桥面板构造细节的应力响应和挠度，提高构造细节的抗疲劳性能，避免正交异性钢桥面板开裂，且可避免钢桥面铺装的破坏。
