The grating sideslip displacement type expansion joint device mainly comprises a fixed cross beam, a sliding cross beam, a track beam and a plurality of ribs, the fixed cross beam and the track beam are arranged on the top faces of beam end concrete on the two sides of an expansion joint in the transverse bridge direction, and the fixed cross beam and the track beam are welded to a plurality of sets of anchoring parts pre-embedded in beam body concrete; a sliding groove is formed in the top face of the track beam, and the sliding cross beam is slidably arranged in the sliding groove of the track beam. The ribs are arranged between the fixed cross beam and the sliding cross beam in parallel, an acute included angle is formed between each rib and the fixed cross beam and between each rib and the sliding cross beam, the two ends of each rib are rotationally connected with the fixed cross beam and the sliding cross beam through pin shafts respectively, and the top surface of each rib is flush with the beam surface. The expansion joint is large in longitudinal and transverse displacement range, good in vehicle passing smoothness, low in noise, not prone to damage and convenient to maintain and repair.
本发明公开一种格栅侧滑位移式伸缩缝装置，主要包括固定横梁、滑动横梁、轨道梁及多根肋条，固定横梁和轨道梁分别横桥向设置在伸缩缝两侧的梁端混凝土顶面，固定横梁和轨道梁分别焊接多组预埋在梁体混凝土内的锚固件；轨道梁顶面设一滑槽，滑动横梁滑动设置在轨道梁的滑槽内；多根肋条平行设置在固定横梁和滑动横梁之间，且每根肋条与固定横梁和滑动横梁有锐角夹角，每根肋条两端分别通过销轴与固定横梁和滑动横梁转动连接，各肋条顶面与梁面齐平。本发明适应伸缩缝纵横向位移范围大，车辆通过平顺性好，噪音低，不易损坏且便于养护和维修。
