Abstract
An improved ladder-supported scaffolding technique and system using a pair of horizontally spaced vertical ladders for supporting staging planks therebetween and held vertically and rigidly by top brackets parallely in front of, along, and spaced from a building structure, and having adjustable brackets attachable to intermediate ladder rungs with staging plank-supporting legs perpendicularly extending toward or away from the building structure.
Claims8
A method of employing a pair of similar ladders each having longitudinal sides joined by transverse rungs for use as a scaffolding structure, that comprises, erecting the ladders vertically with their bottom ends resting on the ground at horizontally spaced positions along a wall of a structure that is to accommodate scaffolding therealong, with the ladders equally spaced in front of the wall with the rungs of the ladders being parallel to said wall;
- inserting braces extending horizontally in the space in front of the structure between corresponding upper rungs of each ladder selected below the topmost rungs thereof and opposing regions of the wall, each brace is substantially V-shaped, having a fixed arm and another arm pivotable about the apex of the V and a rung clamp at said apex, each ladder having a pair of said braces clamped to a selected upper rung, said fixed arms of said pair of braces spaced transversely along the selected rung adjacent to each other and extending perpendicularly to the rung into said space and to said opposing regions of the wall;
- said pivotable arms extending at an acute angle with respect to said selected rung and securing the braces between such selected upper rungs and said opposing regions in a horizontal plane therebetween lying below top ends of the ladders to fix the ladders below said top ends vertically rigidly spaced in front of and in a plane parallel to the wall;
- attaching brackets between corresponding intermediate rungs of each ladder at predetermined levels with a scaffold plank mounted transversely along the structure between the ladder brackets, with each bracket having a leg extending perpendicular to the ladder optionally mountable in said space inwardly toward the structure and outwardly away from the ladder;
- and resting said scaffold plank on and between the bracket legs of each ladder bracket to serve as a scaffold platform extending and supported between the ladders.
