A high spacer chair for concrete reinforcing rods and for receipt in supporting formwork structure which comprises in combination;
- a plastic base and a metal wire standoff spacer member insertably supported therein;
- said metal wire member comprising a material capable of providing the predetermined strength necessary for receiving and supporting a reinforcing rod directly thereon and wherein said metal is subject to corrosion when exposed to the environment, said metal wire member being preformed to a predetermined size, having parallel oriented equilength downwardly depending legs for receipt and securing within the plastic base and an area defined on said member intermediate said legs for receipt of the reinforcing rod thereon,
- said base comprising a tough plastic and including a pair of parallel planar wings with a web transversely joining the wings, said wings comprising feet at outward downwardly directed ends thereof, at least one foot of each wing portion being positively securable on said formwork structure,
- a pair of substantially tubular vertically extending recesses integrally defined with said web, each recess being inwardly of a respective wing and defining a deep hole portion open at its upper end and terminating at its lower end adjacent to but spaced upwardly from a respective bottom foot, the said bottom feet and said wing feet being coplanar, each said recess securely receiving therein a respective leg of said wire member, with the lower end of each said leg abutting against the lower end of its respective hole, the lower end of each leg of said wire member thereby being spaced upwardly from the respective bottom foot, vertical thrusts in said legs of said metal wire member being transmittable directly against the lower end of the respective hole and thence directly to the respective bottom foot and thus to said formwork,
- a pair of vertically extending slots defined in said base at the junction of said wing and said web,
- a trestle member extending upwardly from the base including a pair of legs, and a transverse beam section,
- the legs of said trestle member being receivable in said slots for locating said beam section above said reinforcing rod receiving area on said wire member,
- said web ensuring mutually fixed spaced separation of the legs of the wire member, and said wire member being isolated from the effects of environmental corrosion when said spacer is present in a reinforced concrete structure, and overturning forces applied to said spacer being resisted by the outward separation of said wing feet from the legs of said wire member.
