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:
Disclosed is an economical and effective way of producing a double sided decorative wall using facing panels having a decorative face surface, in particular dry cast concrete panels having a regular surface structure, more preferably an embossed surface, most preferably a patterned surface. Further disclosed are wall components and a wall kit for a double sided decorative wall. The facing panels in the wall are stacked in a back-to-back arrangement into a pair of first and second back-to-back walls, which walls are interconnected by connectors which link at least one facing panel in the first wall to at least one facing panel in the second wall for forming the double sided decorative wall. The connecting members can be in individual connectors, or a combination of connectors for linking multiple facing panels or linking facing panels at corners or curves in the wall. The connectors can be of different length to enable the construction of decorative walls of different thickness. A modular wall system for double sided decorative walls forming both straight and curved walls is also disclosed. The system uses facing panels and connectors, wherein all facing panels are of equal thickness, but may have different lengths and may have different widths. The facing panels of the modular wall system all have graduated lengths, each length being a multiple of a base length L. Thus, the facing panels have lengths of 2L, 3L, 4L, 5L etc. To facilitate the formation of walls with corners, such as right angled corners, the facing panels preferably have a depth which is equal to L or a multiple of L. Building the decorative wall of two partial walls of facing panels with intermediate connectors renders the wall more economical than the previously known walls with base blocks and facing panels suspended from the base blocks on one or both sides.
Abstract:
A stackable concrete wall block is disclosed having a prism shaped body with front, rear top and bottom faces, in a stacked condition, and at least a pair of side walls for placement opposite a like block placed side by side to the wall block, whereby a lip protrudes from at least one of the sidewalls and is coplanar with the front face for spacing the body of the block from that of a like block placed adjacent thereto. As is the case with tapered blocks known in the art, this spacing allows the assembly of curved walls. However, a prism shaped block with parallel side walls and a lip is more easily manufactured than a tapered block with angled side walls, since no movable mold walls are required, when the block is made in a dry casting process. The front face and lip can have an embossed surface structure.
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 generally congruent irregularly-shaped first and second sides extending radially from the first vertex and being rotationally spaced from each other by an angle α of approximately 120°; a second pair of generally congruent irregularly shaped third and fourth sides extending radially from the third vertex and being rotationally spaced from each other by an angle β of approximately 120°; a third pair of generally congruent irregularly shaped fifth and sixth sides extending radially from the fifth vertex and being rotationally spaced from each other by an angle ω of approximately 120°; wherein the sides of each 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, whereby in use in combination with other flagstones, each one of the sides is matingly engageable with the sides of an equivalent pair of sides of a neighboring flagstone.
Abstract:
The present invention provides an apparatus and a method for aging a stone, preferably an artificial stone. The aging device comprises a rotary support operatively connected to a rotary shaft, at least one abrasive tool mounted to the rotary support for roughing and/or polishing a surface of the artificial stone when the rotary support is brought into functional contact with said surface, and biasing means that biasingly connect the abrasive tool to the rotary support. The biasing means urge the abrasive tool away from the rotary support while allowing the same to move toward the rotary support when the rotary support is brought into functional contact with the surface of the artificial stone, thereby allowing the abrasive tool to follow a surface profile of the artificial stone while roughing and/or polishing its surface.
