Longitudinally slidable continuous beam bridge transverse widening connecting structure and construction method
The invention discloses a continuous beam bridge transverse widening connecting structure capable of longitudinally sliding and a construction method. Comprising a groove formed in a new bridge flange plate and provided with an opening facing an old bridge flange plate, circular channel steel located in the groove and provided with an opening facing the old bridge flange plate, an arc-shaped sliding plate located on the inner side face of the circular channel steel and used for reducing friction force, and a solid circular steel pipe located on the inner side of the arc-shaped sliding plate. The transverse connecting steel bar is wound on the outer surface of the solid round steel pipe, one end of the transverse connecting steel bar is implanted into the flange plate of the old bridge, the vertical sliding plate is vertically attached to the end face of the flange plate of the new bridge and used for reducing friction force, and the steel plate is vertically attached to the end face of the flange plate of the old bridge and attached to the vertical sliding plate. The solid circular steel tube can longitudinally slide in the circular channel steel, friction force is reduced through the arc-shaped sliding plates, good sliding deformation in the longitudinal bridge direction can be provided, and the problem that due to the longitudinal deformation difference of a new bridge and an old bridge, too large transverse bending deformation is generated, and consequently a broadened structure cracks and is damaged is fundamentally solved.
本发明公开了一种纵向可滑动的连续梁桥横向拓宽连接结构及施工方法，包括开设于新桥翼缘板内且开口朝向旧桥翼缘板的凹槽、位于凹槽且开口朝向旧桥翼缘板的圆形槽钢、位于圆形槽钢内侧面且用于降低摩擦力的弧形滑移板、位于弧形滑移板内侧的实心圆钢管、绕设在实心圆钢管外表面且一端植入旧桥翼缘板内的横向连接钢筋、竖直贴设于新桥翼缘板端面且用于降低摩擦力的竖向滑移板以及竖直贴设于旧桥翼缘板端面的钢板，其中竖向滑移板和钢板相互贴合。本发明中实心圆钢管在圆形槽钢内可以进行纵向滑动，弧形滑移板降低了摩擦力，能够提供较好的纵桥向滑移变形，从根本上解决了因新旧桥纵向变形差产生过大的横向弯曲变形，导致拓宽结构开裂破坏的问题。
