Spacer elements for corner forming system

Claim 2

A concrete forming system which utilizes a plurality of panel form members disposed in intersecting planar positions to confine and mold concrete being poured to provide an inside corner comprising a spacer-mold element formed integrally of resilient material and having a body component disposed for contact with the poured concrete and accordingly determining a portion of the mold form shape of said corner, a lip element formed with said body and disposed for extension away therefrom and away from the concrete being poured, a form support for said concrete forming system, and an element on said support for extension with said lip element to a position between said panel form members for conjointly holding said form members apart in manner providing a gap therebetween with said gap being occluded and preserved by said lip element and body whereby escape of poured concrete is avoided and whereby removal of said panel form members is facilitated after the concrete has set.

Claim 3

The forming system as set forth in claim 1 wherein said body component provides a corner transition shape between the mold form surfaces defined by said panel forms.

Claim 4

A forming system for use in the construction of poured concrete structures at inside corners thereof comprising a plurality of panel form members having terminal end edges at normal disposition with respect to mold surfaces thereof, said panel form members being disposed in intersecting planar positions at the intended inside corners of said structure to confine and mold the concrete being poured, a spacer-mold unit for use at said inside corner disposed in contact with the end edges of adjacent form panels, said spacer-mold unit being integrally formed of resilient deformable material to include a body component disposed for contact with the poured concrete and accordingly determining a portion of the mold form shape at said inside corner, and a lip component formed with said body and disposed for extension away therefrom and away from the concrete being poured on a line parallel to and spaced apart from a concrete contacting mold form surface of one adjacent panel, the body component for said spacer-mold unit having at least one edge that defines said body disposed in contact with an end edge of one of said panel form members with said body component edge being of height corresponding to the thickness for said panel form members, said lip component at the time of use being operative to hold said panel form members apart in manner providing a gap therebetween with said gap being occluded and preserved by said lip and body components whereby escape of poured concrete is avoided and wherein the removal of said panel form members from a poured inside corner after the concrete has set is facilitated by the deformable resilience of said spacer-mold unit.

Claim 5

A forming system for use in the construction of poured concrete structures at inside corners thereof comprising a plurality of panel form members having terminal end edges at normal disposition with respect to mold surfaces thereof, said panel form members being disposed in intersecting planar positions at the intended inside corners of said structure to confine and mold the concrete being poured, a spacer-mold unit for use at said inside corner disposed in contact with the end edges of adjacent form panels, said spacer-mold unit being integrally formed of resilient deformable material to include a body component disposed for contact with the poured concrete and accordingly determining a portion of the mold form shape at said inside corner, and a lip component formed with said body and disposed for extension away therefrom and away from the concrete being poured on a line parallel to and spaced apart from a concrete contacting mold form surface of one adjacent panel, the body component for said spacer-mold unit having at least one edge that defines said body disposed in contact with an end edge of one of said panel form members with said body component edge being of height corresponding to the thickness for said panel form members, said lip component at the time of use being operative to hold said panel form members apart in manner providing a gap therebetween with said gap being occluded and preserved by said lip and body components whereby escape of poured concrete is avoided and wherein the removal of said panel form members from a poured inside corner after the concrete has set is facilitated by the deformable resilience of said spacer-mold unit.

Claim 6

The forming system as set forth in claim 3 wherein said panel form members are disposed in otherwise conterminous relation with said lip element positioned therebetween.

Claim 7

The forming system as set forth in claim 3 wherein said panel form members are disposed to provide a lap joint corner with said lip element positioned therebetween.

Claim 8

The forming system as set forth in claim 3 wherein said panel members are disposed to form paired inside corners with at least one panel form member itself extending between said corners and accordingly being subjected to longitudinal compressive stress exerted by poured concrete with said longitudinal compressive stress being transmitted to and by an end of an intersecting panel.
