Abstract
The present invention is directed to improved fasteners for securing insulation to a supporting structure, to a method of using the fasteners, and to combination wall structures obtained by such use. The fasteners are adapted to facilitate the securement of relatively thick insulation to a supporting structure, particularly where the supporting structure consists of a relatively hard material, such as aged concrete of high compressive strength.
Claims24
A fastener comprising a substantially flat elongated strip having at least one leg depending therefrom, an arm joined with and extending out from said elongated strip, and an L-shaped member comprising substantially flat first and second legs, said first leg depending from said arm and said second leg extending out from said first leg and away from said elongated strip, said first leg and each of said legs depending from said elongated strip being on the same side of said elongated strip.
A fastener comprising, in combination:
- a stud member comprising a substantially flat elongated strip having at least one leg depending therefrom and having at least one aperture in its surface;
- and
- a bracket comprising (a) a planar web, (b) substantially flat first and second legs depending from opposite ends of said web at substantially a right angle and in opposite directions, and (c) a tab depending from said first leg on the same side thereof as said web;
- said tab extending into said aperture with said first leg in part transversely superposed with said strip and in part transversely extending out from said strip so as to provide a substantially flat arm segment from which said web depends.
A wall structure comprising, in combination:
- a wall or wall-stud assembly;
- an insulation member having front and back surfaces, said back surface facing said wall or wall-stud assembly;
- at least one fastener engaging said insulation member and attached to said wall or wall-stud assembly, said fastener comprising
- (a) a substantially flat elongated strip in substantially contiguous face-to-face relation with said front surface of said insulation member and having at least one leg depending therefrom and penetrating said front surface,
- (b) an arm joined with and extending out from said elongated strip at least to an edge of said insulation member, and (c) an L-shaped member comprising substantially flat first and second legs, said first leg depending from said arm thereto and extending closely adjacent to a side surface of said insulation member, said first leg being equal in length to the width of said side surface, and said second leg extending away from said side surface on that side of said first leg opposite said arm and contiguous with a portion of said wall or wall-stud assembly;
- and
- means attaching said second leg to said wall or wall-stud assembly.
A bracket adapted for engagement with a stud member, said stud member comprising a substantially flat elongated strip having at least one leg depending therefrom and having an aperture in its surface, said bracket comprising (a) a planar web, (b) substantially flat first and second legs depending from opposite ends of said web in opposite directions, said first leg having a first width and sides tapering along at least part of its length and terminating at a narrower second width, and (c) a tab depending at substantially a right angle from said first leg at the terminus of said tapering sides and on the same side of said first leg as said planar web, said bracket being adapted for engagement with said stud member by insertion of said tab in said aperture.
