Methods and apparatus for sidewalk tiles

摘要

A system and method for forming concrete tiles for use in concrete walkways and concrete patios and courtyards. The system includes a unitary frame with two or more slanted sidewalls with a plurality of pickup points placed within an interior opening of the unitary frame. Concrete poured into the interior opening of the frame forms a beveled or slanted concrete sidewalk tile. The pickup points are buried in the beveled concrete sidewalk tiles. When an opening in the pickup points is uncovered, a means to pick and place the beveled concrete sidewalk tiles is provided. Slanted or beveled sidewalls prevent binding to or interference with adjacent slanted or beveled sidewalk tiles to facilitate lifting.

1. A method of removing and replacing sidewalk tiles comprising:
determining the position of a plurality of pickup points within a sidewalk tile formed within a frame, wherein the frame and the sidewalk tile have one or more outwardly beveled sides to avoid interference with one or more adjacent sidewalk tiles; removing a surface concrete layer over each of the plurality of pickup points; coupling cables to each of the plurality of pickup points; pulling up on the cables to lift the sidewalk tile up and away from the one or more adjacent sidewalk tiles to expose a grading for repair; making the repair to the exposed grading; and replacing the sidewalk tile so that the one or more of the outwardly beveled sides of the sidewalk tile form a triangular gap with an outwardly beveled side of an adjacent sidewalk tile.
