Seamless combined bridge expansion device
The invention belongs to a bridge expansion device, and particularly relates to a seamless combined bridge expansion device. Comprising edge beams fixed to beam end concrete structures on the two sides of the expansion joint respectively and at least one middle beam arranged between the edge beams. The middle beams and the adjacent middle beams or edge beams are respectively provided with a storage part and a lap joint part which are matched with each other, the lap joint part comprises a telescopic plate fixed on the expansion joint beam end concrete structure, the outer end of the telescopic plate faces the feeding end of the storage part, the storage part comprises a fixed steel plate fixed on the expansion joint concrete structure, and the outer end of the fixed steel plate faces the feeding end of the lap joint part. The lower surface of one end of the fixed steel plate is a guide surface in guide fit with the front end of the telescopic plate, and a storage cavity capable of containing the telescopic plate is formed below the fixed steel plate. The problems that in the prior art, driving comfort is poor, noise is high, and impact force is large are solved. The device has the advantages of good road surface flatness, comfort in driving, low noise, low device maintenance cost, low failure rate and the like.
本发明属于桥梁伸缩装置，特别是指一种无缝式组合桥梁伸缩装置。包括分别与伸缩缝两侧的梁端砼结构固定的边梁，设置于边梁之间的至少一条中梁；中梁与相邻的中梁或边梁上分别设有彼此适配的收纳部及搭接部，搭接部包括固定于伸缩缝梁端砼结构上的伸缩板，伸缩板的外端朝向收纳部的进料端，收纳部包括固定于伸缩缝砼结构上的固定钢板，固定钢板的一端下表面呈可与伸缩板前端导向配合的导向面，固定钢板下方开设有可容纳伸缩板的收纳腔。本发明解决了现有技术存在的行车舒适度差、噪音高且冲击力大等问题。具有路面平整度好、行车舒适且噪音低，装置维护成本及故障率低等优点。
