The invention discloses a rubber sealing piece for a bridge expansion joint, and relates to the technical field of bridge expansion, the rubber sealing piece comprises a first fixing plate, a second fixing plate and an expansion piece, a first arc-shaped groove and a second arc-shaped groove are formed in the expansion piece, and the first arc-shaped groove and the second arc-shaped groove are symmetrically distributed about the center line of the expansion piece; the outer radian of the first arc-shaped groove is opposite to the outer radian of the second arc-shaped groove, an I-shaped exhaust channel is formed in the telescopic piece and communicates with the first arc-shaped groove and the second arc-shaped groove, limiting blocks are fixedly connected to the telescopic piece, the limiting blocks are symmetrically and evenly distributed about the center line of the telescopic piece, and the telescopic piece is made of ethylene propylene diene monomer. The telescopic part is reasonable in design structure and can be integrally formed by arranging the first arc-shaped groove, the second arc-shaped groove and the I-shaped exhaust channel in the telescopic part in a rubber co-vulcanization mode, and after the telescopic part is extruded by the first bridge section and the second bridge section, the overall pressure of the telescopic part is released.
本发明公开了一种桥梁伸缩缝用橡胶密封件，涉及桥梁伸缩技术领域，包括第一固定板、第二固定板和伸缩件，所述伸缩件中开设有第一弧形槽和第二弧形槽，且第一弧形槽和第二弧形槽以伸缩件中线进行对称分布，第一弧形槽和第二弧形槽的外弧度相对，所述伸缩件内部开设有工型排气通道，工型排气通道与第一弧形槽和第二弧形槽相连通，所述伸缩件上固定连接有限位块，且限位块以伸缩件中线对称均匀分布，所述伸缩件材质为三元乙丙橡胶。本发明设计结构合理，它能够通过在伸缩件内部设置第一弧形槽、第二弧形槽和工型排气通道并利用橡胶共硫化方式一体成形制成，伸缩件在受到第一桥段和第二桥段相互挤压之后，实现伸缩件的整体压力的释放。
