The invention discloses a bridge expansion joint and a construction method thereof, and relates to the expansion joint and the construction method. Bridge end anchoring steel bars are fixed to the outer sides of two steel beams of an expansion joint body, comb plates are fixed to the top of the expansion joint body, a water stop belt is clamped between the two comb plates and the steel beams, the middle of the water stop belt is bent to be provided with a U-shaped section, slope faces are arranged in the middles of the inner sides of the two steel beams, and supporting connecting units are installed between the two slope faces at intervals. Bolt holes are on both sides of the rectangular sleeve, two vertical long-strip-shaped holes are formed in the lower end of a Y-shaped supporting seat, the two vertical long-strip-shaped holes are connected together through two connecting bolts and nuts in an inserted mode, the rectangular sleeve is clamped between the two clamping blocks, the outer side ends of the two clamping blocks are arranged on the two slope faces in a matched mode, the water stop belt is supported by the upper end of the Y-shaped supporting seat, and spring shock absorbers are evenly fixed between the Y-shaped supporting seat and the two clamping blocks. And the slope faces in conical arrangement are arranged between the two sections of steel beams, and a plurality of supporting and connecting units are assembled, so that better shock resistance and adaptability to deformation of a bridge body are achieved, and assembly and maintenance are easy.
一种桥梁伸缩缝及其施工方法，涉及一种伸缩缝及施工方法。伸缩缝主体的两段钢梁外侧固定有桥端锚固钢筋，顶部固定有梳板，止水带夹装在两个梳板与钢梁之间，中间弯设有U形段，两段钢梁内侧中间位置设置有斜坡面，支撑连接单元间隔安装在两个斜坡面之间，矩形套筒两侧有螺栓穿孔，Y形支撑座下端设有两个竖向长条孔，通过两根连接螺栓螺母插装连接在一起，两个夹持块将矩形套筒夹持在中间，且外侧端配合坐设在两个斜坡面上，Y形支撑座上端支撑止水带，弹簧减震器均匀固定在Y形支撑座与两个夹持块之间。两段钢梁之间设置锥状排布的斜坡面并装配有多个支撑连接单元，具有更好的抗震性和对桥体形变的适应性，易于装配维修。
