Abstract
Abstract An upstanding channel member, serving as a mounting for a door or window frame, has a rectangular or trapezoidal central portion received with all-around clearance in a space between two adjoining wall elements and bears with one or two transverse base flanges upon an end face of one or both wall elements. Two flat anchor members, secured to opposite sides of the central channel portion by a dovetail fit, are independently shiftable along these surfaces to fit between courses of building blocks or bricks constituting the wall elements. The mortar bonding these courses together flows into the clearance around the central channel portion and holds it, together with the anchor members, in position between the wall elements.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A moistureproof assembly for affixing a frame to a wall, comprising a pair of wall elements separated by a space, a dampproofing course element of water-impermeable corrosion-resistant material of hollow uniform cross-section over its entire length extending all along said frame, said course element having a trapezoidal-cross-section body tapering away from said frame and projecting into said space, said body having mutually converging legs formed along the exterior thereof with respective channels of dovetail configuration extending the full length of the course element, the interior of said body opening in the direction of said frame, and at least one flange extending transversely to one of said legs and unitary therewith; means for securing a frame element to said flange; and flat dovetail anchors received in said wall and engaging in said channels at selected locations therealong, said channels providing sites for said anchors anywhere throughout the length of said course element.
Claim 2
Dependent Claim
151 words
A moistureproof assembly for affixing a frame to a wall, comprising a pair of wall elements separated by a space, a dampproofing course element of water-impermeable corrosion-resistant material of hollow uniform cross-section over its entire length extending all along said frame, said course element having a trapezoidal-cross-section body tapering away from said frame and projecting into said space, said body having mutually converging legs formed along the exterior thereof with respective channels of dovetail configuration extending the full length of the course element, the interior of said body opening in the direction of said frame, and at least one flange extending transversely to one of said legs and unitary therewith; means for securing a frame element to said flange; and flat dovetail anchors received in said wall and engaging in said channels at selected locations therealong, said channels providing sites for said anchors anywhere throughout the length of said course element.
Claim 3
Dependent Claim
144 words
A moistureproof assembly for affixing frame to a building wall, comprising: a pair of wall elements with substantially coplanar end faces each composed of several courses of building blocks held together by layers of adhesive material, said wall elements being separated by a space generally perpendicular to said end faces; an upstanding channel member of profiled sheet material having a central portion projecting with all-around clearance into said space and further having a base outside said space with said flange means bearing upon at least one of said end faces; a cementitious filler occupying said clearAnce and bonding said channel member to said wall elements; and a pair of flat anchor members positively engaging opposite outer surfaces of said central portion within said filler and extending laterally outwardly therefrom between successive building-block courses of said wall elements in respective layers of said adhesive material.
Claim 4
Dependent Claim
144 words
A moistureproof assembly for affixing frame to a building wall, comprising: a pair of wall elements with substantially coplanar end faces each composed of several courses of building blocks held together by layers of adhesive material, said wall elements being separated by a space generally perpendicular to said end faces; an upstanding channel member of profiled sheet material having a central portion projecting with all-around clearance into said space and further having a base outside said space with said flange means bearing upon at least one of said end faces; a cementitious filler occupying said clearAnce and bonding said channel member to said wall elements; and a pair of flat anchor members positively engaging opposite outer surfaces of said central portion within said filler and extending laterally outwardly therefrom between successive building-block courses of said wall elements in respective layers of said adhesive material.
Claim 5
Dependent Claim
26 words
An assembly as defined in claim 2 wherein said opposite outer surfaces are provided with vertical keying formations matingly receiving adjoining ends of said anchor members.
Claim 6
Dependent Claim
22 words
An assembly as defined in claim 2 wherein said anchor members include with each other an obtuse angle pointing toward said base.
Claim 7
Dependent Claim
28 words
An assembly as defined in claim 4 wherein the profile of said channel member is generally trapezoidal, said outer surfaces converging in a direction away from said base.
Claim 8
Dependent Claim
23 words
An assembly as defined in claim 2 wherein said filler is an overflowing mass of said adhesive material fully enveloping said anchor members.
Claim 9
Dependent Claim
32 words
An assembly as defined in claim 2, comprising a further anchor member positively engaging said flange means and extending into one of said wall elements through said one of said end faces.
