Corrugated steel reinforcing component for old small bridges and culverts in active service
The invention discloses an on-service old small bridge and culvert corrugated steel reinforcing member, relates to the technical field of corrugated steel reinforcement, solves the problem that existing bridge and culvert corrugated steel is poor in durability, and comprises a corrugated steel body, and an anti-fatigue device used for supporting and reinforcing the inner wall of the corrugated steel body is arranged in the corrugated steel body; an anti-fatigue device is arranged in the corrugated steel body, the anti-fatigue device comprises two fixing cylinders which are coaxially arranged with the corrugated steel body, a sliding mechanism is arranged between the inner wall and the outer wall of each fixing cylinder, and one end of each sliding mechanism is rotationally connected with an opening piece. Part of stress is concentrated on the anti-fatigue device, so that the corrugated steel pipe structure is reasonably stressed, the working state of the bridge and culvert corrugated steel under normal load is not changed, the safety and durability of the bridge and culvert corrugated steel are improved, and the service life of the bridge and culvert corrugated steel is prolonged. And meanwhile, the phenomenon that the bridge and culvert corrugated steel has cracks and brittle fractures under the action of long-term overhigh variable stress is also avoided.
本发明公开了一种现役旧小桥涵波纹钢加固构件，涉及波纹钢加固技术领域，解决了现有桥涵波纹钢耐久性差的问题，包括波纹钢本体，波纹钢本体的内部设有用于对其内壁进行支撑加固的抗疲劳装置；抗疲劳装置包括两个与波纹钢本体同轴设置的固定筒，固定筒的内外壁之间设有滑动机构，滑动机构的一端转动连接有撑开件，本发明通过在现有小桥涵波纹钢结构内部设计一个抗疲劳装置，可以提高波纹钢的抗压强度，受到的部分应力集中在抗疲劳装置上，让波纹钢管结构受力合理，使得桥涵波纹钢在正常荷载下的工作状态不会发生变化，从而提高了涵波纹钢的安全性和耐久性，同时也避免在长期的过高变应力的作用下会使得桥涵波纹钢出现裂纹脆性断裂的现象。
