    摘要: 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.

    摘要: 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.
