ENVIRONMENTALLY PROTECTED REINFORCEMENT DOWEL PINS AND METHOD OF MAKING

摘要

Galvanically protected reinforcement dowel pins and methods of producing thesame. 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 asacrificial metal, such as zinc, zinc alloy, magnesium, magnesium alloy,aluminum, or aluminum alloy. The bar or tube comprises steel, carbon steel, orother ferrous metal. The heavy gauge of sacrificial metal is applied to theferrous metal by various processes, such as roll bonding, lock seaming,welding, die casting, flame spraying, plasma spraying, dipping, sinking, anddrawing. The resulting reinforcement dowel pins resist corrosion withoutsacrificing structural integrity, and are reasonable in materials andmanufacturing costs. These dowel pins may be installed in adjacent concretepanels using conventional methods, and therefore do not introduce additionalcosts in installation.
