Abstract
A prefabricated concrete form with vertical spacers between fill forming cladding with cut-outs in the spacers having horizontal rebar received therethrough and received therein. Stand-offs are provided between the vertical spacers with vertical rebar received on the stand-offs. In one version, the stand-offs are attached to the horizontal rebar. In other versions, the stand-offs are attached to the spacers. A cut-out is formed in one of the claddings to form an auxiliary fill space on the outside of the cladding, which when filled with concrete, upon hardening, forms a ledge for supporting a stair structure.
Claims22
In a prefabricated form for hardenable fill material, the improvement comprising:
- (a) a wall section having a first layer of cladding and a second layer of cladding disposed therewith in spaced arrangement and defining a fill space therebetween for receiving the fill material poured into the fill space;
- (b) a plurality of spaced vertically oriented ribs/spacers disposed intermediate the first and second layer of cladding and operatively secured thereto and supporting same thereon;
- (c) a plurality of spaced cut-outs formed in each of the ribs/spacers operative to permit flow of the fill material therethrough, wherein one of the cut-outs in each of the plurality of ribs/spacers is aligned with one of the cut-outs in each of the remaining ribs/spacers;
- (d) at least one first reinforcing bar received through each of the aligned cut-outs, wherein the at least one reinforcing bar is positioned therein and maintained in a predetermined desired position;
- (e) a plurality of stand-offs disposed intermediate the ribs/spacers in vertically spaced arrangement, wherein each of the stand-offs has certain surfaces thereon aligned with the corresponding certain surfaces in each of the remaining stand-offs;
- and,
- (f) a second reinforcing bar received through the aligned certain surfaces in the stand-offs, wherein the certain surfaces in the stand-offs are operative to maintain the second reinforcing bar in a vertically oriented position.
In a prefabricated form for a hardenable fill material, the improvement comprising:
- (a) a fill section having a first layer of cladding and a second layer of cladding disposed in spaced arrangement defining a fill space therebetween for receiving the fill hardenable material poured therebetween;
- (b) a plurality of spaced vertically oriented ribs disposed in the fill space intermediate the first and second layer of cladding;
- and operatively secured thereto and supporting same thereon;
- (c) a plurality of stand-offs disposed intermediate the ribs in vertically spaced arrangement, wherein each of the stand-offs has certain surfaces thereon aligned with respective corresponding certain surfaces in the remaining stand-offs;
- and,
- (d) a reinforcing bar received on the aligned certain surfaces on the stand-offs, wherein the certain surfaces in the stand-offs are operative to locate and maintain the reinforcing bar oriented vertically in a vertically oriented position.
A method of making a prefabricated form for hardenable fill material comprising:
- (a) disposing a first and second fill forming layer of cladding in spaced relationship thereby defining a fill space therebetween;
- (b) disposing a plurality of spaced vertically oriented ribs/spacers in the fill space and securing the first and second layers of cladding to the ribs/spacers;
- (c) providing a plurality of vertically spaced stand-offs with certain surfaces thereon and vertically aligning the certain surfaces;
- and,
- (d) disposing a reinforcing bar in the vertically aligned certain surfaces on the stand-offs thereby positioning the reinforcing bar in a vertical position.
A prefabricated form for hardenable fill material comprising:
- (a) a first and second fill forming boundary member disposed in spaced relationship and defining a primary fill space therebetween;
- (b) a cut-out formed in one of the first and second boundary members operative to permit fill material to flow therethough;
- and
- (c) an auxiliary fill forming boundary member disposed over the cut-out outside said primary fill space and configured to form an auxiliary fill space, wherein upon pouring of fill material in the primary fill space, the auxiliary fill space is filled and upon hardening of the fill material, an auxiliary vertical load bearing surface is formed in the auxiliary fill space.
A method of making a prefabricated hardenable fill material form comprising:
- (a) disposing first and second layers of fill forming material in spaced relationship and forming a primary fill space therebetween;
- (b) forming a cut-out in one of the first and second layers of fill forming material;
- (c) disposing fill forming material over the cut-out and forming an auxiliary fill space in communication with outside the primary fill space;
- and,
- (d) pouring fill material in the primary fill space thereby flowing fill material into the auxiliary fill space and forming an auxiliary vertical load-bearing surface upon hardening of the fill material.
A method of making a prefabricated concrete fill form comprising:
- (a) disposing first and second layers of fill forming cladding material in spaced relationship and forming a primary fill space therebetween;
- (b) forming an auxiliary fill space outside the primary fill space communicating with the primary fill space and pouring concrete in the primary fill space the rebar filling the auxiliary fill space and forming a vertical load-bearing ledge upon hardening of the fill material.
