Abstract
A right-angled triangular shoring or scaffolding frame unit having its acute apices blunted at right angles to the adjacent side and having multiple holes therein adapted for bolt assembly in a plurality of positions. Said triangular units preferably are made from aluminum and used in identical pairs assembled symmetrically to brace a pair of vertical load-bearing aluminum legs, said triangular units having adjacent legs of different lengths whereby the widths of the assembled frames can be varied by bolting the pair(s) of triangular units to each other edge-to-edge between the vertical legs with either the shorter, or alternatively the longer, of the adjacent legs oriented horizontally.
Claims31
A shoring frame brace, comprising said brace being constructed substantially from aluminum rectangular tubing in the form of a right non-isosceles triangle with the acute angled apices formed with short blunted portions at right angles to the respective adjacent leg, each such portion having a pair of lateral bolt holes extending therethrough in a direction parallel to its adjacent leg, and additional pairs of bolt holes perpendicular to the plane of the triangular surface of said brace and through each of said legs at both the outer and the inner portion of each end thereof, all of said pairs of bolt holes being aligned along the length of said legs or of said portions, said outer pairs of holes being adapted for use in bolting said brace to flanges on a shoring frame leg, and said inner pairs of holes being adpated for use in bolting to a bracing stud mount.
A disassemblable, size adjustable, shoring frame system comprising the following structural elements capable of being assembled in the field as a shoring frame:
- a pair of load-bearing tubular frame legs each having an integral pair of parallel longitudinally-extending flanges;
- bracing means for extending between and fastening to each of the frame legs by the respective flanges thereof with said frame legs parallel to each other, said bracing means including at least a pair of substantially identical right triangular braces, wherein at least the two apices of the triangular braces adjacent a hypotenuse thereof are blunted so as to form short blunted portions parallel to a brace leg opposite the blunted apex;
- and
- disconnectable fastening means for demountably joining said bracing means to the flanges of said legs.
A disassemblable, size adjustable, shoring frame system comprising the following structural elements capable of being assembled in the field as a shoring frame:
- a pair of load-bearing tubular frame legs each having an integral pair of parallel longitudinally-extending flanges;
- bracing means for extending between and fastening to each of said legs by the respective flanges thereof with said legs parallel to each other, said bracing means including at least a pair of substantially identical right triangular braces, wherein at least the two apices of the triangular braces adjacent a hypotenuse thereof are blunted so as to form short blunted portions parallel to a brace leg opposite the blunted apex, the blunted portions and the brace legs each being of an appropriate width to fit between the two parallel flanges of the frame legs;
- and
- disconnectable fastening means for demountably joining said bracing means to the flanges of said legs, including bolt holes in said flanges, corresponding perpendicular bolt holes in the brace legs of each of the triangular braces by which the flanges of either leg of each brace can be fastened to said flanges, and perpendicular bolt holes through the blunted portions of said triangular braces to be aligned with selected ones of the bolt holes in the flanges of said frame legs.
