Abstract
Abstract A solid grouted wall is formed of layers of block with spaces being formed within the block or between block to accommodate rebar and concrete. A rebar support comprising two parallel and laterally spaced longitudinally extending rods and a plurality of cross rod members positioned therebetween are positioned on the face shells of the block so the cross rod members extend in the aforementioned spaces. Cross rod members each include at least one and preferably two substantially U-shaped troughs which extend below the plane of the longitudinally extending rods a predetermined distance and which accommodate the horizontally extending rebar. In addition, the respective cross rod members of the rebar supports can be aligned vertically from layer to layer so as to offer support for vertical rebars.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
In a solid grouted wall formed of layers of blocks, with each layer defined by a plurality of blocks positioned in end to end relationship and having parallel face shells and spaces therebetween, and rebar extending along said spaces, the improvement comprising rebar supports comprising two parallel and laterally spaced longitudinally extending rods and a plurality of cross rod members positioned between the rods in spaced relationship and welded to each of the parallel rods along a surface thereof, each cross rod member positioned in a space between face shells and including at least one substantially U-shaped trough bent formed in the cross rod member and extending below the plane of the longitudinally extending rods a predetermined distance to maintain the rebar at or below said plane, said trough in adjacent cross rod members being aligned to accommodate the rebar, said longitudinally extending rods positioned on adjacent face shells to reinforce mortar joints and said cross rod members being in substantially vertical alignment from layer to layer to provide support for vertically positioned rebar.
Claim 2
Dependent Claim
174 words
In a solid grouted wall formed of layers of blocks, with each layer defined by a plurality of blocks positioned in end to end relationship and having parallel face shells and spaces therebetween, and rebar extending along said spaces, the improvement comprising rebar supports comprising two parallel and laterally spaced longitudinally extending rods and a plurality of cross rod members positioned between the rods in spaced relationship and welded to each of the parallel rods along a surface thereof, each cross rod member positioned in a space between face shells and including at least one substantially U-shaped trough bent formed in the cross rod member and extending below the plane of the longitudinally extending rods a predetermined distance to maintain the rebar at or below said plane, said trough in adjacent cross rod members being aligned to accommodate the rebar, said longitudinally extending rods positioned on adjacent face shells to reinforce mortar joints and said cross rod members being in substantially vertical alignment from layer to layer to provide support for vertically positioned rebar.
Claim 3
Dependent Claim
18 words
The solid grouted wall of claim 1, each cross rod member including two U-shaped troughs in spaced relationship.
Claim 4
Dependent Claim
185 words
In a solid grouted wall formed of layers of block in spaced and parallel relationship with layers of brick, concrete filling the spaces therebetween and rebar reinforcing said wall, the improvement comprising a rebar support comprising two parallel and laterally spaced longitudinally extending rods connected by parallel and spaced cross rod members, one of said longitudinally extending rods positioned in a mortar joint on a brick face between layers of brick and the other of said rods positioned in a mortar joint on a block face between layers of block, said cross rod members extending in said spaces filled by concrete and including at least one substantially U-shaped trough bent formed in the cross rod member and extending below the plane of the longitudinally extending rods a predetermined distance to maintain the rebar at or below said plane, said trough of adjacent cross rod members being aligned in a longitudinal direction and accommodating rebar and said cross rod members of adjacent rows being aligned vertically to provide support for vertically positioned rebar positioned at the intersection of the horizontal rebar and the cross rod members.
Claim 5
Dependent Claim
185 words
In a solid grouted wall formed of layers of block in spaced and parallel relationship with layers of brick, concrete filling the spaces therebetween and rebar reinforcing said wall, the improvement comprising a rebar support comprising two parallel and laterally spaced longitudinally extending rods connected by parallel and spaced cross rod members, one of said longitudinally extending rods positioned in a mortar joint on a brick face between layers of brick and the other of said rods positioned in a mortar joint on a block face between layers of block, said cross rod members extending in said spaces filled by concrete and including at least one substantially U-shaped trough bent formed in the cross rod member and extending below the plane of the longitudinally extending rods a predetermined distance to maintain the rebar at or below said plane, said trough of adjacent cross rod members being aligned in a longitudinal direction and accommodating rebar and said cross rod members of adjacent rows being aligned vertically to provide support for vertically positioned rebar positioned at the intersection of the horizontal rebar and the cross rod members.
Claim 6
Dependent Claim
18 words
The solid grouted wall of claim 3, each cross rod member including two U-shaped troughs in spaced relationship.
