Seamless telescopic device
A polyurethane layer is adopted to wrap a whole formed by paired steel plate springs, the whole is arranged between notches in the two sides of an expansion joint, the two steel plate springs in each pair are oppositely arranged in the bridge direction, and spring steel plates of each pair of steel plate springs are connected in the middle in the transverse bridge direction to form a whole. The corresponding ends in the transverse bridge direction are bent in the opposite direction and are fixed to the beam bodies or bridge abutments on the corresponding sides, so that even if the beam bodies on one side in the bridge direction mainly stretch out and draw back to drive the spring steel plates of the steel plate springs on the corresponding sides to stretch or compress in the bridge direction, the spring steel plates of the steel plate springs on the other side can be stretched or compressed in the same mode, and the steel plate springs are not prone to deformation. The polyurethane layers on the two sides in the bridge direction are evenly stressed, so that the polyurethane layers are not prone to being damaged, and the service life of the polyurethane layers is longer. And the polyurethane layer and the steel plate spring have telescopic elasticity, so that the constructed pavement is flat and can adapt to the deformation of the beam end, and the driving is comfortable and smooth.
本发明涉及一种无缝式伸缩装置,采用聚氨酯层包裹成对的钢板弹簧形成的整体,设置于伸缩缝两侧槽口之间,每对的两个钢板弹簧在顺桥向相对设置,且每对钢板弹簧的弹簧钢板横桥向中部连接,形成一个整体,横桥向对应端朝相反方向弯曲,并固定于对应侧的梁体或桥台,使得即使顺桥向一侧的梁体为主要伸缩,带动对应侧钢板弹簧的弹簧钢板沿顺桥向拉伸或压缩,也能够对另一侧的钢板弹簧的弹簧钢板形成同样的拉伸或者压缩,共同分担受力,进而使得顺桥向两侧的聚氨酯层受力均匀,使得聚氨酯层不容易损坏,使用寿命更长;且聚氨酯层和钢板弹簧均具有伸缩弹性,施工后路面平整,能够适应梁端的变形,行车舒适平顺。
