Formwork-free cast-in-place UHPC steel-concrete combined bridge deck slab and construction method thereof
The invention discloses a formwork-free cast-in-place UHPC steel-concrete combined bridge deck slab and a construction method thereof. The formwork-free cast-in-place UHPC steel-concrete combined bridge deck slab comprises riffled plates installed on longitudinal main beams in a welded mode. Shear nails, longitudinal steel bar support plates and vertical supports are welded to the top faces of the riffled plates, the shear nails are longitudinally arranged at the corresponding positions of the longitudinal main beams, the longitudinal steel bar support plates are used for installing transverse steel bars in the bottom-layer steel bars and controlling the distance between the transverse steel bars and the thickness of a steel bar protective layer, and longitudinal steel bars in the bottom-layer steel bars are arranged on the upper sides of the transverse steel bars. Transverse steel bar support plates are welded to the tops of the vertical supports along the line, the transverse steel bar support plates are used for supporting and installing longitudinal steel bars in the top-layer steel bars and controlling the distance between the longitudinal steel bars, and transverse steel bars in the top-layer steel bars are arranged on the upper sides of the longitudinal steel bars. Transverse stiffening ribs are welded on the bottom surface of the checkered steel plate, and baffles are welded on the side edges and the upper side of the beam end; the UHPC concrete is cast in place in a space defined by the checkered steel plate upper baffles. Fatigue damage of common steel bridge decks is avoided, construction waste is avoided, and operation is convenient.
本发明公开了一种无模板现浇UHPC钢混组合桥面板及其施工方法，包括焊接安装在纵向主梁上的花纹钢板；花纹钢板顶面焊接有剪力钉、纵向钢筋支架板和竖向支撑，剪力钉在纵向主梁的对应位置纵向排布，纵向钢筋支架板用于安装底层钢筋中的横向钢筋且控制其间距和钢筋保护层厚度，底层钢筋中的纵向钢筋布设在横向钢筋上侧，竖向支撑沿线顶部焊接横向钢筋支架板，横向钢筋支架板用于支撑安装顶层钢筋中的纵向钢筋且控制其间距，顶层钢筋中的横向钢筋布设在纵向钢筋上侧；花纹钢板的底面焊接横向加劲肋、侧边及梁端上侧焊接挡板；UHPC混凝土现浇在花纹钢板上挡板围成的空间内。本发明避免了普通钢桥面板疲劳病害，无建筑垃圾，作业方便。
