  • Patent number: 6502359
    Abstract: An expendable concrete dowel placement apparatus comprising a concrete form and a dowel holder capable of quickly positioning a dowel perpendicular to the surface of the concrete form, thereby allowing the finished concrete slab to expand and contract relative to a control joint without the dowel causing the concrete to yield. The concrete form maintains a plurality of square or rectangular apertures which receive the dowel bar holders. Each dowel bar holder maintains a plurality of retention clips and a flange located at its open proximal end which positively positions the dowel bar holder within the apertures of the concrete form in a position perpendicular to the front surface of the central vertical member of the concrete form. The concrete form is composed of a non-typical shape which allows the control joint to transfer loads to adjoining concrete slabs through the length of the control joint.
