  • Patent number: 7581709
    Abstract: A system of interconnecting structural components for supporting and forming suspended concrete slabs that allow removal of form panels without disturbing the slab support posts (shores). Additional features of the system accommodate changes in suspended slab thickness, horizontal slab dimensions that are not multiples of the basic component dimensions, slab edge cantilevered form panels, attachment to walls and remote manipulation of form panels from the floor below using an erection staff. The primary system components are panels, support posts, telescopic beams, adjustable hanger connections, wall hangers, wall beams, raking shore assemblies and erection/stripping staffs. Form panels are directly supported by the shores without the use of an intermediate member (usually a beam) that is common practice in the concrete forming industry. The system reduces the number of required components that in turn reduces the capital cost to the user and improves his labor efficiency and quality of the concrete surface.
