CN223867609U - Pull rod type cantilever scaffold movable corner device - Google Patents

Abstract

This utility model discloses a tie-rod type movable corner device for cantilever scaffolding in the field of scaffolding technology. It includes a steel section installed on a structural beam via anchor bolts. One end of the steel section is hinged to a hinge rod, and the end of the hinge rod away from the steel section is hinged to a base. The base is detachably connected to a concrete structure. Two hinge rods are provided, and the two hinge rods form an angle along their length directions. The end of the steel section corresponding to each hinge rod is the end with the smallest lateral distance between them. The steel section is driven by an adjustment unit to swing along the hinge point with the hinge rods to adjust the angle between the length direction of the steel section and the length direction of the hinge rods. By providing two hinge rods with an angle, the load on the hinge rods from the steel section can be distributed between the two hinge rods. Compared to the existing technology that uses a single hinge rod to support the steel section, this reduces the impact of load on the service life of the hinge rod, increases the supporting strength of the steel section, and also reduces the width-direction movement of the steel section.
