INTEGRATED NON-SLIP WASHER

WIPO Patent Application WO/2023/287134

A1

The present invention relates to an integrated non-slip washer, and an objective to be achieved thereby is to: when a steel bracket is installed at a construction site, fix a fastening position of a washer without slipping by concave-convex coupling between the washer and an adapter to enable accurate adjustment without an error, thereby preventing poor construction; and simplify an assembling and installing procedure, thereby shortening working time and improving work stability by omitting an existing welding procedure. An embodiment provides an integrated non-slip washer comprising: a saw-toothed adapter which is formed to have a plate-shape, has a hole extending through the front and the rear surface of the plate, has a saw-toothed concave-convex portion formed on the front surface or the rear surface of the plate, and has catching parts formed at opposite sides of the plate, respectively; and a saw-toothed washer which has a hole corresponding to the hole of the saw-toothed adapter, has a saw-toothed concave-convex portion formed on the front surface or the rear surface thereof, corresponding to the saw-toothed concave-convex portion of the saw-toothed adapter, and has legs extending from respective corner parts thereof, respectively, to be caught to be movable along the catching parts of the saw-toothed adapter.
