The application scope of corrugated steel structures is becoming more and more extensive, mainly used in highway culverts, water pipelines, tunnel linings, integrated pipe corridors and other structural buildings. When used in tunnel lining structures, due to the small gap between the lining corrugated plate and the inner wall of the tunnel, it is necessary to realize the internal connection of the corrugated plate.

[0003] For example, announcement number CN216044808U is named a corrugated steel plate connection structure, which includes a connecting sleeve, a locking piece and a connecting piece. The connecting sleeve is provided with an internal thread and a first external thread, one end of the connecting sleeve is provided with a first limiting flange extending outward, and the locking piece is provided with a screw hole matched with the first external thread; the locking piece is spirally installed on the connecting sleeve, and a second external thread is provided on the outer circumferential surface of the connecting piece. With the help of the connecting sleeve, the locking piece and the threaded connection between the two corrugated steel plates, the two corrugated steel plates are firmly fixed together, with fewer processes and simple operation.
