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.

Abstract: Connectors used in manufacturing composite wall structures to substantially prevent forms from being displaced in response to pressure generated by concrete poured between the forms. In a completed composite wall structure, the connectors extend through two structural layers and an insulating layer positioned therebetween. The composite wall structures are formed by positioning the insulating layer between and in a spaced-apart relationship to the two forms. The connectors are subsequently inserted through the insulating layer and the forms. As concrete is then poured into spaces between the forms and the insulating layer, a bearing surface on a form retention segment, which extends beyond the outer surface of the forms, abuts the forms and prevents them from moving away from the insulating layer. The bearing surface is either directly positioned on the form retention segment or on a form locking device attached to the form retention segment.

Bores through the side rails are positioned between the cross stiffener members and between the ribs in each pair of ribs for joining the side rails together with continuity of the cross stiffener members for maximum dispersal of stress. Holes for wall ties extend through the face of the form panel and between the ribs in each pair of ribs. Fasteners for the ends of the wall ties engage the pairs of ribs to disperse localized stress.

Abstract: An improved system is provided for separation of contiguous concrete portions of a structure. This separation is advantageous in reducing structural failure caused by earth settlement, frost upheaval or excessive underground water pressure by allowing each section of an in-ground concrete structure affected to freely float independent of each other, thereby eliminating the effects of stress on the structure.
