Abstract:
A dowel bar sleeve adapted to receive a dowel bar having substantially planar, substantially parallel upper and lower surfaces, the dowel bar sleeve comprising:a. a substantially planar top section;b. first and second sides attached to the top and extending downwardly from the top;c. a substantially planar bottom section attached to the first and second sides, the bottom section defining a substantially planar surface substantially parallel to the top section, the top section and bottom section of the dowel bar sleeve being spaced apart such that if the dowel bar is inserted into a dowel bar sleeve, the dowel bar sleeve is adapted to substantially prevent the dowel bar from moving in a direction perpendicular to the top and bottom sections of the dowel bar sleeve;d. the top and bottom sections of the dowel bar sleeve are substantially wider than the upper and lower surfaces of the dowel bar so that if the dowel bar is inserted into the dowel bar sleeve, the dowel bar can move in a direction toward and away from first and second sides of the dowel bar sleeve; ande. collapsible fins inside the dowel bar sleeve and extending longitudinally along the interior of the dowel bar sleeve for nominally centering the dowel bar between the first and second sides of the dowel bar sleeve and permitting the dowel bar to move toward and away from the first and second sides of the dowel bar sleeve.
