Reset type bridge expansion joint device
The invention discloses a reset type bridge expansion joint device which aims at solving the technical problems that in the prior art, under the long-term load effect and vibration of vehicle passing, an expansion joint device cannot recover deformation normally, the structural safety of a bridge is affected, and the frequency and cost of maintenance and repair are increased. The expansion joint device comprises expansion joint steel channels which are arranged in an opposite supporting mode, a sealing rubber strip is arranged on the top between the two expansion joint steel channels, a plurality of anchoring steel bars are evenly distributed on the outer sides of the expansion joint steel channels, and limiting mechanisms used for limiting the anchoring steel bars are arranged in the expansion joint steel channels. The anti-fatigue performance of the bridge expansion joint is enhanced, the device can rapidly recover to the initial state after being stressed, the problem that an existing expansion joint device cannot recover deformation is effectively solved, and the stability and safety of a bridge structure are kept.
本发明公开了一种复位型桥梁伸缩缝装置，该伸缩缝装置旨在解决现有技术下在长期荷载作用和车辆通行的震动下，导致伸缩缝装置无法正常恢复形变，这不仅影响了桥梁的结构安全性，还增加了维护和修复的频率和成本的技术问题。该伸缩缝装置包括对撑设置的伸缩缝槽钢，两个伸缩缝槽钢之间的顶部设置有密封橡胶条，伸缩缝槽钢的外侧均布设置有多个锚固钢筋，伸缩缝槽钢的内部设置有用于限制锚固钢筋的限制机构，本发明通过复位机构的设置，增强了桥梁伸缩缝的抗疲劳性能，装置能够在受力后迅速恢复到初始状态，有效解决了现有伸缩缝装置无法恢复形变的问题，保持桥梁结构的稳定性和安全性。
