  • Patent number: 6394410
    Abstract: An adjustable reinforcement insertion guide is installed within the slip form mold of a mobile concrete slip form machine, for guiding steel reinforcement screens into the mold interior during the casting of continuously poured concrete barrier walls (i.e. “Jersey Walls”). The guide is vertically adjustable, in order to clear curbs, open cut joints, etc, as required. Additional adjustment is provided for a series of laterally adjustable outlet panels on the back of the guide, which provide additional accuracy and adjustment in guiding the steel mesh or screen which passes through the guide. The guide is fixed to the mobile slip form machine (with the exception of the vertical adjustment of the guide relative to the slip form machine), and travels with the machine as fresh concrete is introduced into the slip form mold of the machine.
