Field-assembly concrete dowel basket
First Claim
1. An unassembled field-assembly dowel basket for concrete construction configured for assembly into a dowel basket on an as-needed, where-needed basis, comprising:
- a plurality of dowels;
a plurality of clips, each clip configured to removably support one of the dowels, each clip further configured to removably receive wire segments;
the wire segments including a plurality of end wires and a plurality of frame wires;
a plurality of “
T”
connectors removably attachable to the end wires and a plurality shipping wires;
the shipping wires configured to space apart basket sides assembled from the clips and wire segments to position pairs of clips such that each pair of clips supports an associated dowel.

Abstract
A field-assembly dowel basket for concrete construction configured for in-the-field assembly from standardized components. This allows a number of standard components, including clips, connectors and wire frame components, to be conveniently transported and stored on construction sites to facilitate on-site assembly of dowel baskets on an as-needed, where-needed basis. Since the dowel basket components are much smaller than assembled baskets, they can be shipped and stored much more cost effectively. Standardization of components allows mass production, consolidates inventory management, and avoids the need for ad hoc fabrication for each construction site. On-site fabrication largely eliminates welding from the dowel basket fabrication process (wire frame clips may involve welding), avoids shipping of fabricated dowel baskets, and allows assembly of dowel basket by construction workers as opposed to highly skilled welding shops.

17. A method for constructing a concrete road at a road construction site, comprising
manufacturing or obtaining components of field-assembly dowel baskets; -
transporting the components in bulk quantities to the construction site; assembling a dowel basket of desired length from the components at the construction site; positioning the dowel basket at the edge of a first concrete slab to be poured; positioning a concrete form around dowels of the dowel basket, wherein the form comprises notches configured to accommodate the dowels; pouring the first concrete slab so that a first portion of each dowel is embedded in the first slab and a second portion of each dowel extends from the first slab; and after the first slab sets, removing the form and pouring a second concrete slab adjacent to the first concrete slab over the second portions of the dowels so that the dowels span a joint between the first and second concrete slabs; and assembling each field-assembly dowel basket from removably attachable components, comprising; a plurality of dowels; a plurality of clips, each clip configured to removably support one of the dowels, each clip further configured to removably receive wire segments;
the wire segments including a plurality of end wires and a plurality of frame wires;and a plurality of “
T”
connectors removably attachable to the end wires and a plurality shipping wires;
wherein the shipping wires are configured to space apart basket sides assembled from the clips and wire segments to position pairs of clips such that each pair of clips supports an associated dowel. - View Dependent Claims (18, 19)
