  • Patent number: 5261760
    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.
