Abstract:
An improved curb section of precast concrete subdivided into modules by transverse grooves which give the appearance of shorter blocks and provide for fracturing the curb section at those locations. Each module of the curb section has a rearward T-shaped projection. L-shaped projection is formed at each end module of the curb section in proximity to the end face so that L-shaped projections of adjacent curb section form a projection equivalent to a T-shaped projection. T-shaped projections and an adjacent pair of L-shaped projections are anchored by sliding a channel-shaped anchor element which engages the projections and has a V-shaped lower end to penetrate the pavement or ground. The modules of the curb section can be of rectangular shape or tapered thereby defining rectilinear elongated curb sections or curved elongated curb sections which can be fastened adjacent to one another.
Abstract:
A method and apparatus for forming a curb section of a predetermined length sub-divided into modules by transverse grooves which give the appearance of shorter blocks and provide for fracturing the curb section at those locations. Each module of the curb section includes a rearward fastening projection having a vertical bore for passing a nail to engage the curb section to pavement or other base. Such linear mold sections are all that are required when a curve is dictated. The mold sections are sub-divided into the modules to form the curve. The apparatus includes an open frame moving vertically against a platform and mold shoes for pressing down on the concrete when poured in the mold frame, including plugs for forming the tops of the fastening projections. According to the method, the plugs are removed after the mold frame is lifted, and then the shoes are removed to leave the formed curb sections on the bottom wall.
Abstract:
An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of first and second sides extending radially from the first vertex; a second pair of third and fourth sides extending radially from the third vertex; a third pair of fifth and sixth sides extending radially from the fifth vertex; wherein the sides of at least one of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, and the artificial flagstone has no rotational symmetry when rotated about a central axis.
Abstract:
An apparatus for molding dry cast products having a textured side surface is disclosed. The apparatus comprises an open compartment for receiving a dry concrete mixture and a plurality of walls laterally enclosing the compartment. At least one of the walls has a multilevel surface with a plurality of sections in an overhanging relationship with each other and transitional curvilinear steps bridging adjacent one of the sections to impart a textured side surface resembling a natural rockface and allowing stripping of the dry cast products from an open bottom side of the compartment.
Abstract:
An artificial stone is disclosed for use in creating a covering for a supporting surface. The artificial stone includes a body for placement on the supporting surface, which is shaped for mating engagement with like stones with intermediate perimeter joints to produce a continuous surface covering. The stone has a facing surface on the body, which facing surface has a contour defining a surface area and is subdivided by at least one simulated joint into a major surface portion and at least one minor surface portion. The major surface portion is free of simulated joints and extends over at least about 60% of the total surface of the facing surface. The stone further includes at least one perimeter recess in the body for generating a gap between the stone and another like stone in mating engagement therewith, which gap is wider than adjacent the adjoining perimeter joint. Stones of this construction can easily be arranged in a regular, repeated pattern to generate a continuous covering for the supporting surface with the surface of the resulting covering having an irregular, natural appearance. The irregular top contours of the stones, the uneven division of the facing surface and the perimeter recesses and the resulting gaps between mating stones simulate the appearance of a natural stone surface covering for walkways, roadways, pavements or walls.
Abstract:
An artificial stone is disclosed for use in creating a covering a supporting surface. The artificial stone includes a base portion for placement on the supporting surface, which base portion is shaped as a right regular prism for patterned, fitting arrangement of the flagstone with like flagstones to produce a continuous surface covering. The base portion has a regular base contour. The stone further includes a top portion with a facing surface, the facing surface having an irregularly shaped top contour different from the base contour and an intermediate portion connecting the top portion with the base portion. The intermediate portion has an inclined wall extending between the top portion and a sidewall of the base portion. Stones of this construction can easily be arranged in a regular, repeated pattern to generate a continuous covering for the supporting surface without the surface of the resulting covering having a regular, patterned appearance. The irregular top contours of the stones, simulate the appearance of natural stone.
