Anti-clamping cross-seam comb-tooth type bridge expansion device
The invention discloses an anti-clamping cross-seam comb-tooth type bridge expansion device, and solves a problem that wheels and stones are clamped by deep and long potholes of a traditional large comb-tooth type bridge expansion device. The fixed tooth pit slot filling and lifting method comprises steps that the tooth length is increased in the post-cast strip direction of the telescopic device, pit slots with certain lengths of adjacent teeth are covered, inter-tooth cavities with certain lengths corresponding to the models are formed, inter-tooth bearing beams with the corresponding lengths are vertically and movably connected to the corresponding tooth ends, the bearing beams have enough strength, during use, the size of the top surface of the full-pit slot long inner bearing beam is only about 15mm lower than that of the tooth top. According to comb tooth beam seam bolt side pit slot filling and lifting, two steel plates are welded to the movable tooth side through the I-shaped cross section of a fixed tooth side tooth beam, and a 20-25 mm gap needed by stretching and retracting of a fixed tooth I-shaped beam web is reserved. After treatment, a top surface of a pit slot on the movable tooth side is about 20mm lower than the road surface, so the conditions of wheel clamping and stone clamping are avoided.
一种防卡跨缝梳齿型桥梁伸缩装置，解决了传统大型梳齿式桥梁伸缩装置“深长坑槽”卡轮卡石问题。固定齿“坑槽”填抬方法：先向伸缩装置后浇带方向延长齿长并覆盖相邻齿一定长度的坑槽，形成和型号相对应的一定长度的齿间空腔，再在对应齿端上下活动连接相应长度的齿间垫梁，垫梁有足够强度，使用中全坑槽长里垫梁顶面尺寸只低于齿顶15mm左右。梳齿梁缝螺栓侧坑槽填抬是利用固定齿侧齿梁“工”字形断面，在活动齿侧焊接两块钢板，预留20～25mm固定齿“工”字梁腹板伸缩需要的空隙。处理后活动齿侧坑槽顶面比路面低20mm左右，不会发生卡轮和卡石情况。
