Abstract:
1. An apparatus for aligning barrier wall modules atop a retaining wall, comprising: a flat base adapted to be transversely disposed relative to a longitudinal axis of said retaining wall, said flat base adapted to be positioned between adjacent barrier wall modules disposed in end-to-end relation to one another atop said retaining wall; said flat base including a central part, a flat first arm and a flat second arm, said first and second flat arms being integrally formed with and extending from said central part in opposite directions relative to one another and in co-planar alignment with said central part; a retaining wall-receiving notch cut out from said central part, said notch having a depth sufficient to receive a predetermined vertical extent of said retaining wall therein and having a width sufficient to receive a predetermined width of said retaining wall; said flat base further including a first elongate bolt and a second elongate bolt, said first and second elongate bolts being secured to and extending from respective free ends of said first and second flat arms in opposite directions relative to one another and in longitudinal alignment with said first and second flat arms; a first nut in screw-threaded engagement with said first elongate bolt and a second nut in screw-threaded engagement with said second elongate bolt; a first housing that ensleeves said first flat arm and said first elongate bolt and which is slideably mounted with respect to said first flat arm and said first elongate bolt; said first housing being movable toward said central part when said first nut is advanced toward said central part; a second housing that ensleeves said second flat arm and said second elongate bolt and which is slideably mounted with respect to said second flat arm and said second elongate bolt; said second housing being movable toward said central part when said second nut is advanced toward said central part; said first housing adapted to abut a first, highway side of a pair of adjacent barrier modules when said first nut is advanced; said second housing adapted to abut a second, opposite side of said pair of adjacent barrier modules when said second nut is advanced; whereby relative advancement of said first and second nuts brings said pair of adjacent barrier modules into flush relation to one another atop said retaining wall.
