发明名称 Concrete dowel placement sleeves
摘要 Slip and non-slip dowel placement sleeves are disclosed. The slip dowel placement sleeve generally comprises a tubular dowel receiving sheath having a closed distal end and an open proximal end. A connecting means of perpendicular flange is formed around the proximal opening of the sheath to facilitate attachment of the sheath to a concrete form. Smooth sections of dowel rod may then be advanced through holes drilled in the concrete form and into the interior compartment of the sheath. Concrete is poured within the form and the dowel rod remains slidably disposed within the interior of the sheath. Variations of the basic slip dowel placement sleeve of the invention includes a tapered "extractable" sleeve and a corrugated "grout tube" for placement of non-slip dowel or rebar.
