Abstract

An anchor assembly for supporting an insulation panel or blanket on furnace walls which includes an extension member adapted to be fastened to an existing anchor member in order to extend the length of the anchor assembly to accommodate insulation of greater thickness. The extension member has attaching means which engage notches in the existing anchor to hold to extension in position. Different species of the attaching means are disclosed.

Claims

1. A high temperature insulating construction wherein a first metallic stud is attached at one end thereof to a structural supporting member and is disposed essentially perpendicular to the surface of the structural supporting member, said first metallic stud having at least two anchor-engaging notches spaced along the length thereof, the improvement comprising:

a. a second metallic stud having at least one anchor-engaging notch, a portion of said second metallic stud overlapping a portion of said first metallic stud and the remaining portion of said second metallic stud extending outwardly from the end of said first metallic stud essentially perpendicular to and away from said structural supporting surface,

b. means attached to said second metallic stud comprising;

i. a tube portion slidably encircling at least a portion of said overlapping portion of said first metallic stud whereby said second metallic stud and said attached tube portion may be slidably located in a desired position along the length of said first metallic stud,

ii. a notch-engaging portion including a tab, said tab being bent into engagement with one of said anchor-engaging notches on said first metallic stud to retain said second metallic stud in a selected position with respect to said first metallic stud; and

c. anchor means positioned on said second metallic stud and engaging an anchored-engaging notch thereon whereby a body of insulating material greater in thickness than the length of said first metallic stud is superimposed over the structural supporting member and is pierced by said first and second metallic studs and retained thereon by said anchor means on said second metallic stud.

2. An insulating construction as recited in claim 1 wherein said tube is welded to said second metallic stud.
