CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. § 119(a) from Colombian application serial number NC2022/0013124 filed on Sep. 15, 2022, which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The present invention relates to scaffolding devices or systems located on the outer wall of buildings to act as support to workers and enable safe work.

BACKGROUND OF THE INVENTION

In the state of the art there are diverse systems, devices and methods for conducting construction work at various heights in a safe manner by using scaffolds and other accessories. For example, U.S. Pat. No. 6,575,268 shows a scaffolding system for access to the surface of a structure, which comprises: a first extension ladder; a second extension ladder; several brackets of scaffolding. The scaffolding system is adapted to be connected to the structure's surface. The brackets comprise a first bar with a first end, a second end, and a hollow interior. The first bar includes a planar pad connected to the second end. The planar pad has a plurality of holes and it is adapted to be connected to a planar surface. A second bar has a first end and a second end. The first end of the second bar is connected to the first end of the first bar and is extended in a fixed angle with respect to the first bar. The second bar includes a planar pad which has several holes connected to its second end and adapted to be connected to said planar surface. A third bar standing within the hollow interior of the first bar in a telescopic arrangement protrudes out from the hollow interior. The third bar of the brackets fit inside the chosen ones and the rungs of the ladders, and are held within the rungs between a final piece connected to the third bar and the first end of the first bar. The end piece has a diameter larger than the internal diameter of the rungs. A platform can be set through a rung of the first ladder and a rung of the second ladder. The first and second extension ladder are held vertically and substantially parallel to the planar surface.
Similarly, EP2871304 discloses a self-climbing scaffolding system for building construction that has at least one rail, shoes anchored through slings to a concrete section of the building and adapted for guiding the rail in a climbing direction. The self-climbing scaffold has a work platform supported by the rail comprising at least one substantially horizontal guide and an outer formwork movable along the guide. A guide element is coupled to the rail in a pivotable manner with respect to an axis of rotation. The guide element comprises at least a first guide surface, in a prior position before the threading position for threading the rail in a free shoe, which is projected with respect to the rail through the anchor of the free shoe. The first guide surface is in contact with the free shoe in said prior position and straightens the rail with respect to the shoe at the same time that said first guide surface moves in a guided manner in the shoe pivoting with respect to the rail. The scaffolding system additionally comprises guide means for guiding the rotation of the guide element with respect to the corresponding rail while it goes up, between the prior position before the threading position and the threading position to allow the threading of the rail with the shoe. The guide means comprises a curve slot in the guide element and a coupling going through the curved slot and through which the guide element is arranged coupled to the rail.
