Movable tooth end pressing plate type telescopic device for highway bridge
The invention discloses a movable tooth end pressing plate type telescopic device for a highway bridge. The movable tooth end pressing plate type telescopic device for the highway bridge is composed of structural units, and each structural unit comprises a movable tooth plate, a fixed plate, a tooth end pressing displacement box and an anchoring part. By innovatively adding the pressing connectingmechanism to the tooth end of the movable toothed plate, the current situation that the expansion joint of the comb plate is stressed and the bolt at the fixed end is prone to falling off is improved, the service life of the expansion joint of the comb plate is greatly prolonged, meanwhile, the waterproof sealing strip is added, the construction difficulty of the comb plate is simplified, and thesealing effect is improved.
本发明公开了一种公路桥梁用活动齿端压紧板式伸缩装置，由结构单元式组成，所述结构单元包括活动齿板、固定板、齿端压紧位移箱和锚固件。本发明创新性的通过在活动齿板的齿端部增加压紧连接机构，改善梳型板伸缩缝受力状态及固定端螺栓容易脱落的现状，大大提高了梳型板伸缩缝使用寿命，同时增加防水密封条简化了梳型板施工难度，提高了密封效果。
