The utility model discloses a safety anti-falling device for bridge construction, which relates to the technical field of bridge construction and comprises a main frame, two plug connectors are fixedly arranged on the left side of the outer surface of the main frame, two splicing mechanisms are arranged on the right side of the outer surface of the main frame, and sliding grooves are formed in the left end and the right end of the front side of the surface of the main frame. And an adjusting plate is slidably arranged in the sliding groove, positioning grooves are evenly formed in the rear side of the surface of the adjusting plate, and a locking mechanism is arranged at the position, located on the rear side of an opening of the sliding groove, of the upper end of the main frame. Compared with an existing common bridge construction safety anti-falling device, the bridge construction safety anti-falling device has the advantages that the length of the splicing device can be flexibly adjusted according to actual conditions, the use requirement of the device is met, the application range of the device is effectively expanded, use is more flexible, and when two anti-falling devices are spliced, the splicing efficiency is improved. No extra bolt fixing piece is needed, the splicing operation is simple, convenient and efficient, and use is more convenient.
