Equidistant displacement bridge expansion joint device
The invention discloses an equidistant displacement bridge expansion joint device which comprises a bridge expansion joint, corner steel plates are fixed to the inner side of the bridge expansion joint in a right opposite mode, a plurality of supporting steel bars are erected between the two corner steel plates, and the distance between the end of a first support steel bar and the corner of each corner steel plate is not smaller than the maximum expansion displacement distance of the expansion joint; the device is characterized in that balancing seats are welded on the corner steel plates at the two end parts; sliding beams perpendicular to the corner steel plate are welded on the two opposite balancing seats; a plurality of groups of telescopic position adjusting plates are arranged between the two sliding beams; and each group is composed of twotelescopic position adjusting plates. According to the equidistant displacement bridge expansion joint device, synchronous equidistant displacement can be achieved, so that gaps between expansion joint profile steel are kept within a safe (jumping-free) range, in addition, the hinged chain plates can form an independent supporting system for the telescopic position adjusting plates, and the overall deformation resistance of the telescopic positioning plate is greatly improved.
本发明公开了一种等距变位桥梁伸缩缝装置，包括桥梁伸缩缝，所述桥梁伸缩缝内侧正对固定有转角钢板，两所述转角钢板之间架设有多条支撑钢条，所述第一支架钢条端部与转角钢板转角之间间距不小于伸缩缝最大膨胀移位距离；其特征在于：两端部的所述转角钢板上焊接有配平座；两正对所述配平座上焊接有与转角钢板垂直的滑梁；两所述滑梁之间布置有多组伸缩调位板；每组所述伸缩调位板由两伸缩调位板组成，本发明的等距变位桥梁伸缩缝装置，能够实现同步等距变位，从而使伸缩缝型钢之间的缝隙保持在安全（无跳跃）范围，另外，铰接链板能够对伸缩调位板形成独立支撑体系，大大提高伸缩调位板整体抗变形力。
