Bridge expansion joint device
A bridge expansion joint device comprises a joint crossing plate and a fixing plate which can move relatively and longitudinally, the joint crossing plate is provided with a rack arranged above an expansion joint in a crossing mode, supporting beams distributed at intervals in the longitudinal bridge direction are installed above the rack, and each supporting beam is distributed in the transverse bridge direction and forms a crisscross structure with the rack; the bottom of each supporting beam is provided with first connecting frames in one-to-one correspondence with the racks at intervals in the transverse bridge direction, the first connecting frames are connected to the corresponding racks and can longitudinally move relative to the racks, and all the supporting beams are connected into a whole through second connecting frames. According to the bridge expansion joint device, the supporting beams installed above the racks of the joint crossing plate and the racks are of a crisscross structure, when a non-motor vehicle passes through the expansion joint device, the phenomenon that tires are clamped in gaps of the comb plates is avoided, the driving safety is improved, in addition, the supporting beams are connected into a whole, the structure of the expansion joint device is firmer, and the service life of the expansion joint device is prolonged. The connecting frame at the bottom of the supporting beam and the rack can move relatively and longitudinally, and normal functions of the expansion joint device are not affected.
一种桥梁伸缩缝装置，包括能相对纵向移动的跨缝板和固定板，跨缝板具有跨设在伸缩缝上方的齿条，在齿条上方安装有沿纵桥向间隔分布的支撑梁，每根支撑梁均沿横桥向分布而与齿条呈纵横交叉结构，每根支撑梁的底部沿着横桥向间隔设置有与齿条一一对应的第一连接架，第一连接架连接在对应齿条上且能与齿条相对纵向移动，全部支撑梁通过第二连接架连接成一体。该桥梁伸缩缝装置安装在跨缝板的齿条上方的支撑梁与齿条呈纵横交叉结构，非机动车通过伸缩缝装置时，不会发生轮胎卡在梳齿板间隙内的现象，提高了行车安全性，此外，支撑梁连接成一体可使伸缩缝装置的结构更牢固，支撑梁底部的连接架与齿条之间能相对纵向移动，不影响伸缩缝装置正常功能。
