Abstract
Abstract Reinforcing sections which are two-dimensional or angled and/or C-shaped can be non-positively connected at least in pairs to form self-supporting reinforcements which have any desired shape and are rigid and resist tension and compression. The sections are connected by causing them to extend one into the other, hooking one onto the other and snapping one onto the other.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
148 words
A reinforcement assembly for reinforced-concrete structures such as slabs, beams, columns and the like, said assembly comprising at least two reinforcing sections each comprising a plurality of stirrups lying in respective parallel planes and in mutually spaced relationship, said stirrups each having at least two legs at substantially right angles to one another, the ends of one leg of each of said stirrups being bent inwardly toward the other of said legs to form a loop, and at least one pair of longitudinal reinforcing rods lying in a common plane perpendicular to the planes of said stirrups and permanently affixed to the other leg thereof; and a further reinforcement member having longitudinally extending reinforcing rods parallel to the reinforcing rods of said sections, said sections and said member being interfitted so that said loops of said stirrups of said sections hook onto said reinforcing rods of said member.
Claim 2
Dependent Claim
148 words
A reinforcement assembly for reinforced-concrete structures such as slabs, beams, columns and the like, said assembly comprising at least two reinforcing sections each comprising a plurality of stirrups lying in respective parallel planes and in mutually spaced relationship, said stirrups each having at least two legs at substantially right angles to one another, the ends of one leg of each of said stirrups being bent inwardly toward the other of said legs to form a loop, and at least one pair of longitudinal reinforcing rods lying in a common plane perpendicular to the planes of said stirrups and permanently affixed to the other leg thereof; and a further reinforcement member having longitudinally extending reinforcing rods parallel to the reinforcing rods of said sections, said sections and said member being interfitted so that said loops of said stirrups of said sections hook onto said reinforcing rods of said member.
Claim 3
Dependent Claim
60 words
The assembly defined in claim 1 wherein said member is of ladder construction with said rods thereof forming structures bridged by spaced apart rungs, said reinforcing rods of said member having a transverse spacing substantially equal to the distance between the bights of the loops of said stirrups and said other legs thereof as measured along said one legs thereof.
Claim 4
Dependent Claim
19 words
The assembly defined in claim 2 wherein said stirrups of said sections interdigitate with one another along said assembly.
Claim 5
Dependent Claim
51 words
The assembly defined in claim 3 wherein the stirrups of at least one of said sections are of generally C-shaped configuration and having a further leg projecting substantially at right angles from the other leg thereof and having a hooked extremity engaging one of the reinforcing rods of the other section.
Claim 6
Dependent Claim
53 words
The assembly defined in claim 3 wherein said sections and said members and dimensioned such that two legs of each stirrup must be deflected into an angle in excess of 90* upon assembly of said member and said section whereby said member and said sections are retained under internal stress against relative displacement.
Claim 7
Dependent Claim
33 words
The assembly defined in claim 3 wherein said longitudinal rods of each section and said member are transversely spaced by a distance equal to the product of an integer and in unit distance.
Claim 8
Dependent Claim
22 words
The assembly defined in claim 3 wherein said member is provided with an eye and enabling manipulation thereof by a lifting device.
Claim 9
Dependent Claim
46 words
The assembly defined in claim 3 further comprising a planar reinforcement structure consisting of longitudinal and transverse reinforcing bars permanently fixed together overlying said sections parallel to saId member and a hold-down structure engaging the longitudinal rods of said sections for locking said reinforcement structure thereagainst.
Claim 10
Dependent Claim
35 words
The assembly defined in claim 8 wherein said hold-down structure includes a pair of C-profile elements inserted between said stirrups of said sections from opposite direction and interfitting to retain said reinforcement structure in place.
Claim 11
Dependent Claim
67 words
The assembly defined in claim 3 wherein the stirrups of each of said sections generally of C-shaped configuration having further legs extending generally at right angles to their relative other leg and provided with loops at the extremity of said further legs, said assembly further comprising another member of ladder construction having parallel reinforcing rods interconnected by rungs and engaged by said loops of said further legs.
Claim 12
Dependent Claim
25 words
The assembly defined in claim 10 further comprising structures extending parallel to said members along the respective reinforcing rods thereof and interconnecting said members together.
Claim 13
Dependent Claim
39 words
The assembly defined in claim 11 wherein said structures are formed by transverse reinforcing stirrups hooked over the reinforcing rods of both said members and reinforcing rods extending longitudinally across said stirrups of said structures and permanently bonded thereto.
