Reinforcing structure for bridge with veneer stress damage caused by hinge joint failure
The invention discloses a reinforcing structure for a bridge with veneer stress damage caused by hinge joint failure, and belongs to the field of bridge reinforcing. The structure comprises a flange channel steel and reinforced concrete. The flange channel steel is tightly attached to the bottom of a bridge plate, the reinforced concrete is located in the flange channel steel and comprises longitudinal reinforcing steel bars, U-shaped reinforcing steel bars and concrete; the longitudinal reinforcing steel bars are arranged in the longitudinal direction of the groove, and the two ends of the upper portions of the U-shaped reinforcing steel bars are planted in bridge plate lower holes in the two sides of the hinge joint respectively. The U-shaped steel bars comprise upper U-shaped steel barsand lower U-shaped steel bars. The upper U-shaped steel bars and the lower U-shaped steel bars each comprise two side vertical steel bars and a bottom transverse steel bar, and the bottom transversesteel bars are connected with the bottom ends of the two side vertical steel bars; and the longitudinal steel bars are arranged in the lower U-shaped steel bars and are crossly connected with the bottoms thereof. The shear resistance of the transverse reinforcing steel bars and the bending resistance of the longitudinal reinforcing steel bars can be brought into full play; the friction resistanceof up-and-down movement at the hinge joint of the bridge plate is increased, the influence of hinge joint failure is made up, and the overall stress capacity of the bridge plate is improved.
本发明公开了一种用于铰缝失效造成单板受力病害桥梁的加固结构，属于桥梁加固领域。包括翼缘槽钢和钢筋混凝土。翼缘槽钢紧贴于桥板底部，钢筋混凝土处于翼缘槽钢内，钢筋混凝土包括纵向钢筋、U形钢筋和混凝土，沿凹槽纵向设置有纵向钢筋，U形钢筋的上部两端均分别植于铰缝两侧的桥板下部孔洞内。U形钢筋包括上部U形钢筋和下部U形钢筋。上部U形钢筋和下部U形钢筋均包括两侧竖直钢筋和底部横向钢筋，底部横向钢筋连接两侧竖直钢筋的底端。纵向钢筋置于下部U形钢筋内并与其底部交叉连接。该发明能够充分发挥横向钢筋的抗剪性能和纵向钢筋的抗弯性能；增大桥板铰缝处上下运动的摩阻力，弥补铰缝失效的影响，提高桥板整体受力能力。
