SELF-STRESSING ARCHITECTURAL CASTING TABLES

Architectural Casting Table

"With the casting surface independent from the stressing frame, the deck remains true and smooth. The hydraulically operated side rails drop down to allow edge picking of the panels. Our new tables greatly reduce the daily forming and casting cycles and allow us to efficiently produce the high quality architectural panels."

Wells Concrete Products

In 2009, Wells Concrete opened a new prestressed/precast plant in Albany, Minnesota. General Manager Gregg Jacobson describes the Albany site as "state–of–the–art with considerable focus in the areas of productivity and 'lean management'." The new facility features all indoor production and was constructed using concrete elements, including double tee members produced on site.

The plant has several state–of–the–art architectural casting tables from Hamilton Form. The tables have a self–stressing steel sub–frame and hydraulically operated side rails. The sub–frame is made up of two wide flange longitudinal beams that are topped with back–to–back channels. Stressing bars run through the channels to carry the prestress load.

Wells installed 2x6s and a wood deck followed with a self–leveling epoxy coating to create a glass–like finish for casting architectural panels on top of the frame. The casting surface moves independently from the frame, protecting it from stress cracks and checking so that the surface remains durable and smooth.

Jacking abutments are anchored to counter–weights at the end of the beds to resist the overturning moment caused by eccentric strand loading. To allow for flexibility in locating strand, jacking plate assemblies that move horizontally are located on each end of the bed. The jacking plates are made up of two vertical plates with a space between them so that strands can also be located vertically, as needed, throughout the slot.

The side rails are hydraulically operated, and hinge away from the table for stripping. Once the product is stripped, the rails rotate back into position. The side rails accept bolted–on risers for casting thicker products. When vibration is required, two lines of Vibrotrack are located under the table.
