  • Dowels for jointed concrete and methods of forming and using the same
    Patent number: 9611593
    Abstract: A concrete dowel tube made of carbon steel comprises a welded longitudinal seam.
    Type: Grant
    Filed: October 24, 2016
    Date of Patent: April 4, 2017
    Inventor: Christopher P. Schenk
  • Dowels For Jointed Concrete and Methods of Forming and Using the Same
    Publication number: 20170067212
    Abstract: A method of forming concrete dowel tubes comprises forming such dowel tube from a roll of steel sheet material and occurs in a continuous process rather than indexed manner. A method of grouting concrete dowel tubes into holes formed in existing cured concrete comprises pumping grout through the dowel tubes to backfill the grout around the dowel tubes between the dowel tubes and the holes.

  • Environmentally protected reinforcement dowel pins and method of making
    Patent number: 7553554
    Abstract: Galvanically protected reinforcement dowel pins and methods of producing the same. In one embodiment, the reinforcement dowel pins comprise a bar or tube, the longitudinal exposed surfaces of which are covered by a heavy gauge of a sacrificial metal, such as zinc, zinc alloy, magnesium, magnesium alloy, aluminum, or aluminum alloy. The bar or tube comprises steel, carbon steel, or other ferrous metal. The heavy gauge of sacrificial metal is applied to the ferrous metal by various processes, such as roll bonding, lock seaming, welding, die casting, flame spraying, plasma spraying, dipping, sinking, and drawing. The resulting reinforcement dowel pins resist corrosion without sacrificing structural integrity, and are reasonable in materials and manufacturing costs. These dowel pins may be installed in adjacent concrete panels using conventional methods, and therefore do not introduce additional costs in installation.
