Prestressed Vertical Cantilever Panels
FP McCann Prestressed Vertical Cantilever Panels
The FP McCann Prestressed Vertical Cantilever Panel system provides the user with a more cost and time-efficient system when comparing against a traditional on-site in-situ wet-cast system.
FP McCann's Prestressed Vertical Panels allow greater strength in a more slender panel than a comparable thicker traditional in-situ wall.
Key Features of Prestressed Vertical Cantilever Panels:
- The vertical cantilever panels are prestressed, allowing greater strength in a more slender panel.
- Prestressing reduces the incidence of tensile cracking in the panels.
- The concrete used for the prestressed panels is designated as a C50/60 grade.
- The foundation can be individually designed to suit site and loading requirements.
- The prestressed panels are tongue and grooved together, allowing effective sealing between units without stressing the sealant.
- The units are lighter – height for height – so require smaller site lifting vehicles.
- The prestressed unit can be lifted and handled more easily on site.
- The panels are supplied with a tongue and groved joint in the vertical plane to assist with wall alignment, load share and ease of sealing. Manufactured on 70mm long prestressing beds, the panels are prestressed during manufacture, which provides an inherent enhanced strength and resilience to many types of retained materials. Retained heights of up to 4m can be achieved for many material types.
Where vertical cantilever panels are designed for wind only, such as a security wall or fire wall, effective eights of up to 7.50m can be achieved.
The units are cast as standard with a Class A steel mould finish to one side and all edges complete with hand trowelled finish to the other face.
During the casting process, cast in Wavy Tail Lifters can be cast in the top edge of the panel to assist with on site installation.
