Novel double-layer plate-truss combined rigid frame bridge compression area plate-truss connecting structure and bridge
A lower chord beam is connected between adjacent lower chords in the transverse bridge direction, the lower chord beam is provided with a lower-layer steel bottom plate close to 0 # block concrete, the lower-layer steel bottom plate is connected with the lower chords and the bottom of the lower chord beam, lower-chord secondary beams are arranged on the lower-layer steel bottom plate at intervals in the longitudinal bridge direction, and the lower-chord secondary beams are connected with the lower-layer steel bottom plate. The lower chord beam is provided with a transition force transmission plate away from the 0 # block concrete, the transition force transmission plate is connected with the bottom of the lower chord and the bottom of the lower chord beam, longitudinal stiffening ribs are arranged on the transition force transmission plate at intervals in the transverse bridge direction, transverse stiffening ribs are arranged on the transition force transmission plate at intervals in the longitudinal bridge direction, and shear nails are arranged on the inner side of the lower chord and the top face of the lower layer steel bottom plate respectively. A lower-layer concrete plate is arranged on the lower-layer steel bottom plate in a pouring mode and connected with 0 # block concrete, and a filling layer is arranged in a gap between the lower-layer concrete plate and the lower chord beam. Most of the stress of the lower chord member is transmitted to the 0 # block concrete through the lower layer concrete plate, so that the force transmission uniformity and reliability are improved.
本发明关于一种新型双层板桁结合刚构桥受压区板桁连接构造，横桥向相邻下弦杆之间连接有下弦横梁，下弦横梁靠近0#块混凝土设有下层钢底板，下层钢底板连接下弦杆和下弦横梁的底部，下层钢底板上沿纵桥向间隔设有下弦次横梁，下弦横梁远离0#块混凝土设有过渡传力板，过渡传力板连接下弦杆和下弦横梁的底部，过渡传力板上沿横桥向间隔设有纵向加劲肋，过渡传力板上沿纵桥向间隔设有横向加劲肋，下弦杆内侧和下层钢底板顶面分别设有剪力钉，下层钢底板上浇筑设有下层混凝土板，下层混凝土板连接0#块混凝土，下层混凝土板与下弦横梁之间的空隙中设有填充层。本发明将下弦杆大部分受力通过下层混凝土板传递给0#块混凝土，改善了传力均匀性和可靠性。
