Comb tooth type bridge expansion joint device
A comb tooth type bridge expansion joint device comprises a first comb tooth plate and a second comb tooth plate which can move relatively in the longitudinal direction, and is characterized in that sliding grooves are formed in the comb tooth side wall of the first comb tooth plate and are horizontally distributed in the length direction of comb teeth, and limiting pieces are arranged on the comb tooth side wall of the second comb tooth plate in an outward protruding mode; the limiting piece extends into the sliding groove and can longitudinally slide relative to the sliding groove. The comb tooth type bridge expansion joint device has the advantages that the longitudinal sliding groove is formed in the comb tooth side wall of the first comb tooth plate, the limiting piece installed on the comb tooth side wall of the second comb tooth plate can stretch into the longitudinal sliding groove, and when the expansion joint device conducts longitudinal displacement, the limiting piece moves relatively along the longitudinal sliding groove, therefore, the first comb plate and the second comb plate can be always limited at the horizontal position, and the phenomenon that the comb plates upwarp to affect driving safety is avoided.
一种梳齿型桥梁伸缩缝装置，包括能纵向相对移动的第一梳齿板和第二梳齿板，其特征在于：在第一梳齿板的梳齿侧壁上开有滑槽，滑槽沿着梳齿长度方向水平分布，在第二梳齿板的梳齿侧壁上向外凸设有限位件，限位件伸入至所述滑槽内并能相对滑槽纵向滑动。本发明的优点在于：该梳齿型桥梁伸缩缝装置通过在第一梳齿板的梳齿侧壁上开设纵向滑槽，安装在第二梳齿板的梳齿侧壁上的限位件能伸入至纵向滑槽内，伸缩缝装置进行纵向位移时，限位件沿着纵向滑槽进行相对移动，从而可以将第一梳齿板和第二梳齿板始终限位在水平位置，避免发生梳齿板上翘现象而影响到行车安全。
