State and AASHTO Girder Side Forms and Soffits are typically designed to be non-self-stressing and are installed between abutments at the precast plant. Forms can be a split design to allow use of internal fillers to produce multiple products using the same top and bottom components. Under form ties and top ties are normally used to hold dimensional tolerances. Multiple form section lengths can be used to adjust your required casting length as well as future bed modifications.
Haunch Girder forms are designed and manufactured to meet the specific geometry for a specific job. A soffit is supported on a framework to hold the specific slope or radius required for the bottom of the girder. Sideforms are configured to the necessary cross-section throughout the girder from center to end to include thickened areas for load support. Forms are designed to overcome the large hydrostatic loads that are developed. Top-ties and underties spaced properly maintain critical dimensional tolerances.
Optional Features Include:
Multiple vibration choices can be built into the forms.
Several approaches to handling the forms can be customized to meet specific needs.
Multiple pour access openings can be added as required.
An Adjustable Inverted Tee can be designed to be highly adjustable to cast a wide variety of inverted tee configurations and L-beams. While most inverted tee forms are designed to be self-stressing, non-self-stressing designs can be provided. From a complex multiple configuration form to a simple single product design, Hamilton Form Company will design and build the form to your needs.
The Double Tee is one of the hardest working forms in a precast plant. Hamilton Form Company has more experience in providing Double Tee forms to precasters than any US manufacturer. All forms are designed for your specific needs in your market area. Forms are typically designed to be self-stressing for your required prestress load. Factors that help dictate design include product width, product depth, stem size and location, and stress load. Hamilton Form will design and manufacture the form that fits your needs.
Hamilton Form’s Architectural Casting Table is designed to produce prestressed panels with an architectural finish. The understructure is made up of paired channels with stressing bars running through the channels. Load is transferred through the bars to the jacking abutments. The table is topped with a wood deck finished by the precaster to create the desired architectural finish. This design leaves the casting surface totally unaffected by stress loads.
Optional Features Include:
Fixed steel side rails
Hydraulically operated side rails
Adjustable jacking plates and hanging weldments
Spandrel loading capacity on one or both sides of the table
Vibrotrack™ vibration system attached to the underside of the table
