Abstract
In a universal, reusable system for molding concrete or other settable fluids for use in building construction, an apertured composite plastic panel is provided for use in the framing system in which the plastic panel, rather than being of a honeycomb structure, includes a single face sheet which serves as a pour side surface, with an array of truncated pyramids having central apertures extending rearwardly from the back side of the sheet.
Claims13
In a forming system for molding elements from a settable material for use in the construction of buildings, a light weight panel for use as a wall in a framing system comprising
- a sheet having a front surface and an array of hollow polygons integrally formed in a back surface thereof so as to project out in a rearward direction from said sheet;
- and,
- inserts captured within said polygons, said inserts having surfaces which are flush with the front surface of said sheet such that the front surface of said sheet forms a smooth molding surface.
