  • Patent number: 6167669
    Abstract: A clear, permanent form, for steel reinforced concrete structures. Sections of the clear form, are to be factory extruded, from a clear polyvinyl chloride material, so as to make the assembly of the forms, the installation of the steel and utilities, and the inspections that are required, easier. The clear forms will protect the steel reinforced concrete structures from the elements that cause these structures to fail. The clear form consists of two factory extruded profiles, that are totally different in shape. The sections that make up the form, can be modified, cut to any length or angle and assembled on site. It takes two sections, of one profile, to form both vertical sides of the form, and two sections, of the other profile, are horizontally inserted, between the vertical side sections, to create an elongated empty container. The assembled clear form is 7⅝ inches wide and 8 inches high, and is open on four sides.
