Severe cold area bridge joint structure and construction method
A severe cold area bridge joint structure and a construction method relate to a connecting joint structure and a construction method. Fixed comb plates are fixed on the upper surfaces of the connecting ends of the two sections of beam bodies, a movable comb plate is arranged between the fixed comb plates, a boss is arranged at the bottom of the beam body connecting end, lower positioning channel steel is fixed on the boss, a V-shaped waterstop is arranged between the two pieces of lower positioning channel steel, the movable comb teeth and the fixed comb teeth can only slide in the horizontaldirection, a rib is arranged in the middle of the beam body connecting end, upper positioning steel channels are fixed on the ribs, a square corrugated steel plate is fixed between the two upper positioning steel channels, a plurality of groups of through holes are formed in the square corrugated steel plate, screw rods are inserted among the through holes, nuts are screwed on the screw rods on two sides of the through holes, a horizontal steel plate is laid above the square corrugated steel plate, and a plurality of pressure springs are fixed between the horizontal steel plate and the movablecomb plate. And the square corrugated steel plate is arranged between the two sections of beam bodies, and is matched with the screw rod and the nut to play a role in damping and buffering, thereby being more suitable for deformation displacement of bridges in severe cold areas caused by frost heaving.
一种严寒地区桥梁连接缝结构及施工方法，涉及一种连接缝结构及施工方法。两段梁体连接端上表面固定有固定梳板，固定梳板之间安装有活动梳板，梁体连接端底部有凸台，凸台固定有下定位槽钢，两根下定位槽钢之间有V形止水带，动梳齿与定梳齿之间仅能进行水平方向滑移，梁体连接端中间位置有肋条，肋条固定有上定位槽钢，两根上定位槽钢之间固定有方波形钢板，方波形钢板开设多组穿孔，穿孔之间插装丝杆，丝杆位于穿孔的两侧旋靠有螺母，水平钢板铺设在方波形钢板上方，与活动梳板之间固定有多根压簧。在两段梁体之间安装方波形钢板，再配合丝杆和螺母起到阻尼缓冲作用，更适应严寒地区桥梁因冻胀问题导致的形变位移。
