Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
A reinforcement for concrete, comprising a pair of assembled reinforcing sections each including a plurality of longitudinally spaced right-angled transverse rods having corresponding sets of legs lying in respective mutually perpendicular planes, and a respective longitudinal rod extending at least the full length of the reinforcing section and secured to all of the legs of each set to one side of the respective plane, the legs of a set of one of said sections interdigitating with the corresponding legs of a set of the other section so as to be coplanar therewith and having their longitudinal rods to the same side of their common plane, whereby the interdigitated legs are adaptable for disassembly or assembly by relative rotation of said sections about one of the longitudinal rods of the interdigitated sets; and a generally U-shaped clip engaging and straddling a leg of each of the interdigitated sets for retaining the interdigitating legs in coplanarity.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
18 words

Claim 4
Dependent Claim
28 words
The reinforcement defined in claim 1 wherein each of said sections has a length equal to the product of an integer and a unit length of modular construction.
