DEVICE IN CONCRETE BLOCKS |
摘要 |
An arrangement in concrete blocks which are intended to be positioned end-to-end to form barriers for e.g. roadways and parking lots. The concrete blocks have an elongate shape with an essentially triangular cross-sectional configuration with rounded side walls, and are interconnected by means of T-shaped metal pieces , the latter being secured in the end faces of the blocks during the casting thereof and formed with cross-bars, the interconnection of the blocks being effected in that two such cross-bars at adjoining end faces of two concrete blocks positioned end-to-end are enclosed by a tubular member, whereby the blocks are locked together. The blocks may be provided with a device widening their upper part and increasing the ability of the block to guide vehicles softly back to the roadway. |
