Joint-crossing vehicle passing device for bridge expansion joint construction period
The invention relates to a joint-crossing vehicle passing device for a bridge expansion joint construction period. The device comprises a joint-crossing main beam; the bottom surfaces of the two endsof the joint-crossing main beam are each welded with a backing plate with a certain thickness; the distance between the two backing plates is greater than the width of a bridge expansion joint; the two ends of the joint-crossing main beam are each provided with a ramp beam; the bottom faces of the ramp beams are flush with the bottom faces of the backing plates at the bottom of the joint-crossingmain beam; the ramp beams are welded to the ends of the joint-crossing main beam; and the end faces of the ramp beams are not higher than the joint-crossing main beam. According to the device, normalpassing of vehicles on a bridge in an expansion joint construction period and a maintenance period can be guaranteed, expansion joint concrete maintenance is not affected, the cost is low, and the comprehensive benefits are high.
本发明涉及一种桥梁伸缩缝施工期的跨缝通车装置，包括一跨缝主梁，跨缝主梁的两端底面分别焊接一有一定厚度的垫板，两垫板之间的距离大于桥梁伸缩缝的宽度；跨缝主梁两端分别设一坡道梁，坡道梁的底面与跨缝主梁底部的垫板底面齐平，坡道梁与跨缝主梁的端部焊接，且坡道梁的端面的高度不高于跨缝主梁的高度。本发明，能保证伸缩缝施工期间及养护期内桥上车辆正常通行，且伸缩缝混凝土养护不受影响，成本低，综合效益高。
