Concrete floor forming system

Claim 2

A concrete forming system comprising: a plurality of forms each having a substantially planar upper wall extending to curved shoulders at each edge thereof and side walls depending from the shoulders and each including an upper outwardly tapered portion extending to a lower portion with the lower portions of the side walls of each form extending parallel to each other and perpendicularly to the upper wall; the upper wall and the side walls of each form extending to open ends with an integral lip extending from one end thereof with the outer surface of the lip being substantially aligned with the inner surface of the walls and shoulders of the forms such that the lip receives and supports the opposite end of an adjacent form to position the outer surfaces of the upper walls and the side walls of the adjacent forms in substantial alignment across the joint therebetween; a plurality of end caps each having an upper wall and side walls which are similar in cross-section to the upper wall and the side walls of the forms and extending to a transversely disposed outwardly tapered end wall, said end caps receiving the forms therein; the side walls of the forms and end caps each having at least one set of holes formed therethrough with each set of holes including at least two vertically spaced holes formed through the lower portion of the side wall; a plurality of wooden stringers each extending adjacent to the side wall of at least one form and each stringer having a plurality of equally spaced locating pin receiving apertures formed therein in spaced relation one from the other along the length thereof; a plurality of nails each extending through at least one of the holes of each set of holes in the side wall of the form and end caps and into the wooden stringer extending adjacent thereto for supporting the form on the stringer; and a plurality of post shores supporting the stringers and having locating pins extending from the upper ends thereof in engagement with the apertures of the stringers, thereby supporting the form secured thereto.

Claim 3

A concrete forming system comprising: a plurality of forms each having a substantially planar upper wall extending to a pair of curved shoulders and a pair of side walls each depending from one of the shoulders and each comprising an upper outwardly tapered portion and a lower portion extending perpendicularly to the upper wall; the upper wall and the side walls of each form extending to open ends with one end of each form having an integrally formed outwardly projecting interconnecting lip extending around the ends of the upper wall and side walls with the outer surface of the lip being aligned with the inner surface of the upper and side walls of the forms such that the lip receives and supports the opposite end of an adjacent form with the outer surfaces of the upper walls and the side walls of the two forms extending substantially continuously across the joint therebetween; each of the forms having at least two longitudinally spaced sets of holes formed through each side wall thereof with the holes of each set including at least two vertically spaced holes extending through the lower perpendicularly disposed portion of the side wall; integral reinforcing ribs extending transversely from the inner surface of the forms at spaced longitudinal points; a plurality of end caps each having an upper wall, curved shoulders, and side walls dimensioned to receive the upper wall, the shoulders, and the side walls of the forms therein and a transversely extending end wall whereby the end caps close the open ends of the forms; a plurality of wooden stringers each extending between the side walls of a pair of adjacent forms; a plurality of nails extending through the holes in the side walls of the forms and into the adjacent stringers to support the forms on the stringers with the positioning of the upper walls of the forms relative to the stringers depending on the hole of each set that receives the nail; a plurality of post shores supporting the stringers and the forms supported thereby with each post shore having a locating pin extending therefrom, the post shore including means for adjusting the height thereof; and each of the stringers having a plurality of equally spacer apertures formed therein along the longitudinal length thereof receiving the locating pins of the post shores.

Claim 4

A concrete forming system comprising: a plurality of forms each having a substantially planar upper wall extending to a pair of curved shoulders and a pair of side walls each depending from one of the shoulders and each comprising an upper outwardly tapered portion and a lower portion extending perpendicularly to the upper wall; the upper wall and the side walls of each form extending to open ends with one end of each form having an integrally formed outwardly projecting interconnecting lip extending around the ends of the upper wall and side walls with the outer surface of the lip being aligned with the inner surface of the upper and side walls of the forms such that the lip receives and supports the opposite end of an adjacent form with the outer surfaces of the upper walls and the side walls of the two forms extending substantially continuously across the joint therebetween; each of the forms having at least two longitudinally spaced sets of holes formed through each side wall thereof with the holes of each set including at least two vertically spaced holes extending through the lower perpendicularly disposed portion of the side wall; integral reinforcing ribs extending transversely from the inner surface of the forms at spaced longitudinal points; a plurality of end caps each having an upper wall, curved shoulders, and side walls dimensioned to receive the upper wall, the shoulders, and the side walls of the forms therein and a transversely extending end wall whereby the end caps close the open ends of the forms; a plurality of wooden stringers each extending between the side walls of a pair of adjacent forms; a plurality of nails extending through the holes in the side walls of the forms and into the adjacent stringers to support the forms on the stringers with the positioning of the upper walls of the forms relative to the stringers depending on the hole of each set that receives the nail; a plurality of post shores supporting the stringers and the forms supported thereby with each post shore having a locating pin extending therefrom, the post shore including means for adjusting the height thereof; and each of the stringers having a plurality of equally spacer apertures formed therein along the longitudinal length thereof receiving the locating pins of the post shores.

Claim 5

The concrete forming system according to claim 2 wherein the forms are molded with the interconnecting lips and reinforcing ribs integral with the upper and side walls.
