Abstract

Abstract A concrete form has an embossed forming panel for molding a facade of brickwork in a particular pattern on a concrete wall or the like. Specially constructed support flanges are secured to the marginal borders of the panel on the exterior face of the latter to prevent undesired deformation of the borders. Each flange has a panel engaging surface and a plurality of projections on the surface adapted to be received within depressions in the borders presented by the brickwork pattern. In the preferred embodiment, the panel is embossed to resemble an English cross-bond brickwork pattern, and the marginal borders vertically traverse the pattern through vertically aligned joints in alternate courses, the flanges having similarly arranged projections to be received within the spaced depressions presented by the aligned, vertically spaced joints.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 200 words
A construction form including: a normally upright panel embossed to present a masonry pattern in one face of the panel and an impression of said pattern in the opposite face, said pattern defining a plurality of offset courses, each having a series of stretchers, presenting a number of vertical joints between the stretchers with the joints in each course vertically misaligned relative to vertical joints in adjacent courses, said one face having a vertical, marginal border traversing said courses, said border terminating at one lateral edge of said panel, a number of said series of stretchers extending across said border to said edge, said border having a plurality of vertically spaced depressions defined by the joints in certain of said courses; and an elongate, vertical flange rigidly secured to said panel along said border for reinforcing said panel against buckling, said flange including a longitudinal surface contiguous with said border and in contact with the stretchers presented therealong, said surface having a plurality of vertically spaced projections disposed to be received within the depressions, whereby said surface contacts substantially the full length of said border to prevent deformation of the latter, said flange being laterally offset from said one edge.
Claim 2
Dependent Claim 200 words
A construction form including: a normally upright panel embossed to present a masonry pattern in one face of the panel and an impression of said pattern in the opposite face, said pattern defining a plurality of offset courses, each having a series of stretchers, presenting a number of vertical joints between the stretchers with the joints in each course vertically misaligned relative to vertical joints in adjacent courses, said one face having a vertical, marginal border traversing said courses, said border terminating at one lateral edge of said panel, a number of said series of stretchers extending across said border to said edge, said border having a plurality of vertically spaced depressions defined by the joints in certain of said courses; and an elongate, vertical flange rigidly secured to said panel along said border for reinforcing said panel against buckling, said flange including a longitudinal surface contiguous with said border and in contact with the stretchers presented therealong, said surface having a plurality of vertically spaced projections disposed to be received within the depressions, whereby said surface contacts substantially the full length of said border to prevent deformation of the latter, said flange being laterally offset from said one edge.
Claim 3
Dependent Claim 33 words
A form as claimed in claim 1, wherein each of said projections has a shelf formed in its base, said shelf extending parallel to said surface in substantially coplanar relationship to the latter.
Claim 4
Dependent Claim 33 words
A form as claimed in claim 2, wherein each of said projections is transversely wedge-shaped, having an outermost sharp edge and a beveled shoulder extending between a respective shelf and said sharp edge.
