Abstract
A system for forming concrete structural elements including a plurality of runners forming a spaced array; a plurality of supports extending upwardly from and connecting intersecting runners; and a plurality of coffer plates secured in position over the supports by a plurality of anchor nuts capable of interacting with the concrete poured to form the structural element. The coffer plates initially act as a mold for the structural element being formed. Thereafter, the array of runners and supports are used to suspend finishing components (plumbing lines, eletrical conduit, electrical wiring and fixtures, ceilings, non-load-bearing walls, etc.) from the structural element without requiring alteration of the concrete forming the structural element.
Claims39
An apparatus for forming concrete structural elements comprising:
- (a) falsework means for supporting the structural element in position during formation;
- (b) a plurality of runners positioned on the falsework means to form an array;
- (c) a plurality of supports engaging intersecting runners forming the array and extending from the array, each support further comprised of a base portion including a plurality of apertures and terminating in a pylon portion which defines a centrally disposed cavity and which terminates at an opening;
- (d) a plurality of coffer plate means engaging the plurality of supports and combining to define a concrete receiving cavity;
- and
- (e) anchor means for securing the coffer plate means to the supports and including means for interacting with concrete used in forming the structural element;
- so that concrete poured into the concrete receiving cavity fills the cavity defined by the coffer plate means and interacts with the anchor means so that, after the concrete has cured and the falsework means has been removed, finishing components are capable of being suspended from the array of runners and supports without altering the concrete comprising the structural element.

An apparatus for forming concrete structural elements comprising:
- (a) a falsework means for supporting the structural element in position during formation;
- (b) a plurality of runners positioned on the falsework means to form an array;
- (c) a plurality of supports engaging intersecting runners forming the array and extending from the array;
- (d) a plurality of substantially flat plates engaging the plurality of supports and combining to form at least two groups, located in different planes, and wherein spaces developed between the flat planes located in one plane and the flat plates located in an other plane are enclosed by a plurality of skirt means comprising a peripheral frame terminating in at least one flange having apertures extending therethrough and capable of receiving means for attaching the flange of the skirt means to be selected flat plates adjacent the spaces to be enclosed;
- and
- (e) anchor means for securing the flat plates to the supports and including means for interacting with concrete used in forming the structural element;
- so that concrete poured over the concrete receiving surface forms the structural element and interacts with the anchor means so that, after the concrete has cured and the falsework means has been removed, finishing components are capable of being suspended from the array of runners and supports without altering the concrete comprising the structural element.
