Abstract
The specification discloses a method and associated products for adding stirrup reinforcements to a concrete pipe reinforcing cage in which a mat composed of a plurality of sinusoidal shaped stirrup members joined by tie wires is joined to a cage with the sinusoidal stirrup members oriented circumferentially with respect to the cage rather than longitudinally.
Claims10
A concrete pipe reinforcing cage and stirrup reinforcement assembly comprising:
- a generally cylindrical reinforcing cage including circumferential wires extending around said cage and generally longitudinal wires extending longitudinally with respect to said cage and being joined to said circumferential wires;
- a mat joined to said cage which is comprised of a plurality of generally sinusoidal shaped stirrup members, each comprised of nodes and antenodes, said stirrup members being oriented generally parallel to one another and being oriented circumferentially with respect to said cage with said nodes projecting generally radially from said cage, said mat further including a plurality of tie wires oriented generally longitudinally with respect to said cage and being secured to said stirrup members to join them together each of said sinusoidal stirrup members being manually bendable and each of said nodes being open at the bottom and being open between one another in a given stirrup member, except where joined by said antenodes, whereby said mat can be manually, arcuately shaped along the length of said sinusoidal stirrup members to conform to the circumference of said cage.
A stirrup reinforcement mat including a plurality of stirrup projections joined together, the improvement comprising:
- a plurality of generally sinusoidal shaped stirrup members, each comprised of nodes and generally flat antenodes, said stirrup members being oriented generally parallel to one another with said antenodes lying in a base plane and with said nodes projecting from said base plane;
- a plurality of tie wires oriented generally parallel to one another and generally perpendicular to said stirrup members, said tie wires being joined to said stirrup members;
- each of said sinusoidal stirrup members being manually bendable and each of said nodes being open at the bottom and being open between one another in a given stirrup member, except where joined by said antenodes, whereby said mat can be manually, arcuately shaped along the length of said sinusoidal stirrup members to conform to the circumference of said cage.
