Abstract
Abstract Mold fabrication apparatus for forming molds is disclosed. The mold fabrication apparatus includes edge members (10) with lipped flanges (12) which extend rearwardly from the mold face (11), and brackets (14) which are notched to engage with the lipped flanges (12) at any desired positions along each edge member (10). The brackets (14) are flanged to enable them to be secured to a surface to locate the edge members (10).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
234 words
A mold supporting bracket for supporting concrete formwork upon a supporting surface, the concrete formwork being in the form of an elongate lipped-channel section of the type having a channel web, the front face of which forms a mold wall section, channel flanges extending rearwardly along opposite edges of the channel web and opposed channel lips extending inwardly along the free edges of the channel flanges, said mold supporting bracket including: a rigid side wall having a front end portion which when pivoted about an axis normal to the channel web to incline said front end portion relative to the channel flanges is receivable between the channel flanges and the opposed channel lips; an upper recess and a lower opposed recess extending inwardly from respective upper and lower edges of said front end portion and being engageable about the innermost edges of the opposed channel lips upon pivoting said front end portion about said axis so as to locate the lipped-channel section relative to said bracket, and a support mounting adjacent the rear end of said side wall and engageable with the supporting surface to hold said bracket and the located lipped-channel section in a selected orientation relative to said supporting surface, said support mounting being in the form of an apertured integral base wall extending substantially perpendicularly from and along the lower edge of said side wall rearwardly of said front end portion.
Claim 2
Dependent Claim
234 words
A mold supporting bracket for supporting concrete formwork upon a supporting surface, the concrete formwork being in the form of an elongate lipped-channel section of the type having a channel web, the front face of which forms a mold wall section, channel flanges extending rearwardly along opposite edges of the channel web and opposed channel lips extending inwardly along the free edges of the channel flanges, said mold supporting bracket including: a rigid side wall having a front end portion which when pivoted about an axis normal to the channel web to incline said front end portion relative to the channel flanges is receivable between the channel flanges and the opposed channel lips; an upper recess and a lower opposed recess extending inwardly from respective upper and lower edges of said front end portion and being engageable about the innermost edges of the opposed channel lips upon pivoting said front end portion about said axis so as to locate the lipped-channel section relative to said bracket, and a support mounting adjacent the rear end of said side wall and engageable with the supporting surface to hold said bracket and the located lipped-channel section in a selected orientation relative to said supporting surface, said support mounting being in the form of an apertured integral base wall extending substantially perpendicularly from and along the lower edge of said side wall rearwardly of said front end portion.
Claim 3
Dependent Claim
36 words
A mold supporting bracket according to Claim 1, wherein said support mounting is spaced rearwardly from said opposed slots by a distance equal to or greater than half the spacing between said upper and lower recesses.
Claim 4
Dependent Claim
40 words
A one-piece mold supporting bracket according to claim 1, wherein said side and base walls are formed whereby a further one of said mold supporting brackets is nestable within the region formed between said side wall and said base wall.
Claim 5
Dependent Claim
41 words
A mold supporting bracket according to claim 1, wherein said front end portion is provided with an intermediate slot for releasable engagement about adjoining lips of adjacent channel members stacked one upon the other to form a composite lipped channel section.
Claim 6
Dependent Claim
51 words
A mold supporting bracket according to claim 1, wherein there is provided a plurality of pairs of opposed slots in said front end portion of said side wall and wherein lines extending between respective pairs of said upper and lower recesses are inclined to said base wall at different selected angles.
Claim 7
Dependent Claim
234 words
A mold supporting bracket for supporting concrete formwork upon a supporting surface, the concrete formwork being in the form of a elongate lipped-channel section of the type having a channel web, the front face of which forms a mold wall section, channel flanges extending rearwardly along opposite edges of the channel web and opposed channel lips extending inwardly along the free edges of the channel flanges, said mold supporting bracket including: a rigid side wall having a front end portion which when pivoted about an axis normal to the channel web to incline said front end portion relative to the channel flanges is receivable between the channel flanges and the opposed channel lips; a plurality of pairs of upper and lower recesses extending inwardly toward each other from respective upper and lower edges of said front end portion , each pair defining a line extending therebetween, said lines being inclined at different selected angles relative to said lower edge wherein the opposed channel lips are engagable with one of said pairs to locate the lipped-channel section at a selected inclination relative to said bracket, and an integral base wall extending along said side wall rearwardly of said front end portion, said base wall being apertured to enable said bracket to be secured to a supporting surface to hold said bracket and the located lipped-channel section in a selected orientation relative to the supporting surface.
Claim 8
Dependent Claim
234 words
A mold supporting bracket for supporting concrete formwork upon a supporting surface, the concrete formwork being in the form of a elongate lipped-channel section of the type having a channel web, the front face of which forms a mold wall section, channel flanges extending rearwardly along opposite edges of the channel web and opposed channel lips extending inwardly along the free edges of the channel flanges, said mold supporting bracket including: a rigid side wall having a front end portion which when pivoted about an axis normal to the channel web to incline said front end portion relative to the channel flanges is receivable between the channel flanges and the opposed channel lips; a plurality of pairs of upper and lower recesses extending inwardly toward each other from respective upper and lower edges of said front end portion , each pair defining a line extending therebetween, said lines being inclined at different selected angles relative to said lower edge wherein the opposed channel lips are engagable with one of said pairs to locate the lipped-channel section at a selected inclination relative to said bracket, and an integral base wall extending along said side wall rearwardly of said front end portion, said base wall being apertured to enable said bracket to be secured to a supporting surface to hold said bracket and the located lipped-channel section in a selected orientation relative to the supporting surface.
Claim 9
Dependent Claim
212 words
Concrete formwork including elongate lipped-channel section of the type having a channel web, the front face of which forms a mold wall section, channel flanges extending rearwardly along opposite edges of said channel web, opposed channel lips extending inwardly along the free edges of said channel flanges and a plurality of supporting brackets engageable with said lipped-channel section at selected positions along said lipped-channel section, each of said brackets including: a rigid side wall having a front end portion which when pivoted about an axis normal to said channel web to incline said front end portion relative to said channel flanges is receivable between said channel flanges and said opposed channel lips; upper and lower opposed recesses extending inwardly from respective upper and lower edges of said front end portion wherein said opposed channel lips are engagable with said opposed recesses to locate said lipped-channel section at a selected inclination relative to said bracket, and an integral base wall extending substantially perpendicularly from and along the lower edge of said side wall rearwardly of said front end portion, said base wall being apertured to enable said bracket to be secured to a supporting surface to hold said bracket and said located lipped-channel section in a selected orientation relative to the supporting surface.
