INC 17978 Concrete Paving Joint Dowel Unit

An item fabricated from steel rods. It consists of two separate identical sections, each having a side frame and a fluted center rod to which dowels are welded. In assembling the two sections as a unit, the free end of each dowel of each section engages a loop at the top of the side frame of the other section and the center rods assume positions parallel to each other with a narrow space between. The center rods, in addition to serving as supports for the dowels, also serve as retainers for an expansion joint filler strip or a contraction joint steel plate when a strip or plate is installed in the space between them. It may be provided with tubes for installation on the dowels to provide clearance for expansion. It is specially designed for installation in the concrete at the contraction and/or expansion joints of highway or other concrete pavement to minimize the load transfer problems caused by heavy wheel loads.

Additional Information for Concrete Paving Joint Dowel Unit

Concrete Paving Joint Dowel Units are components used in the construction of concrete pavements. They are typically made of steel and are designed to provide load transfer and prevent the formation of cracks in the pavement.

These dowel units are specifically used to connect adjacent concrete slabs or panels in a pavement. They are inserted into pre-drilled holes in the concrete and provide a mechanical connection between the slabs. This connection helps to distribute the load evenly across the pavement and prevent differential movement between the slabs.

The dowel units are typically installed at regular intervals along the joint between the slabs. They are designed to withstand the heavy loads and traffic that the pavement will experience. The size and spacing of the dowel units will depend on the specific requirements of the pavement design.

In the supply class Scaffolding Equipment And Concrete Forms, the Concrete Paving Joint Dowel Units are categorized as a component used in the construction of prefabricated structures and scaffolding. They are an essential part of the overall system used to create durable and stable concrete pavements.

Overall, Concrete Paving Joint Dowel Units play a crucial role in ensuring the longevity and performance of concrete pavements by providing load transfer and preventing the formation of cracks.
