Abstract

A refractory support device comprising two elongated members pivotally connected at one end and adapted to be attached to shaped connecting surfaces, and an insulated structure comprising connecting surfaces having the support devices attached thereto and having refractory material covering the surfaces and surrounding the support devices.

Claims

1. A variable angle refractory anchor comprising:

(a) a first flag elongated member having straight sides and an arcuate end;

(b) a second flat elongated member having straight sides and an arcuate end;

(c) connecting means pivotally joining the arcuate ends of said first and second members, said connecting means being located a distance inward from said arcuate ends equal to the radius of curvature of said arcuate ends; and

(d) each of said elongated members including at least one tab formed therein; and

each of said tabs extending away from on another.

2. The device of claim 1 wherein each of said members has a plurality of tabs extending away from one another.

3. The device of claim 2 wherein said connecting means is a rivet.

4. The device of claim 3 wherein said arcuate ends are semi-circular with a radius of one half the width of said elongated members.

5. A refractory insulated structure comprising:

(a) first and second surface members joined at a common edge;

(b) a refractory support device having a pair elongated members, said members having an arcuate end and being pivotally joined at said arcuate ends, said elongated members having straight sides with one side of each elongated member attached to one of said surface members with said common edge being positioned in contact with each of said elongated members; and

(c) a layer of refractory material on both of said surface members substantially surrounding said refractory support device.

6. The structure of claim 5 wherein said surfaces join at a right angle.

7. The structure of claim 5 wherein said surfaces join at an acute angle.

8. The structure of claim 5 wherein said surfaces join at an obtuse angle.

9. The structure of claim 5 wherein said surfaces join at varying angles along said edge, and a plurality of said support devices are spaced along said edge.
