O IFIII I \\\\l INVENTOR BERNARD E. CURRAN /Ql w K NEY United States Patent O 3,714,747 FASTENING MEANS FOR DOUBLE-SKIN FOAM CORE BUILDING PANEL Bernard E. Curran, Sewickley, Pa., assignor to H. H. Robertson Company, Pittsburgh, Pa. Filed Aug. 23, 1971, Ser. No. 174,105 Int. Cl. E04c 1/10, 2/20 US. Cl. 52-309 6 Claims ABSTRACT OF THE DISCLOSURE A double-skin foam core building panel presenting an inboard side segment along one side and an outboard side segment along its opposite side-the side segments being adapted to be assembled in lapped interfitted relation without externally visible fasteners. Hidden fastening means in the form of a clip and fastener is provided for securing the inboard side segment of the panel to the subgirt of a structural framework.

BACKGROUND OF THE INVENTION (1) Field of the invention-This invention relates to double-skin foam core building panels, more particularly to fastening means for securing the panels to the structural framework of a building.

(2) Description of the prior art.Double-skin insulated building panels are well known in the prior art for use in the construction of buildings, see US. Pat. 2,047,154 (C. J. 'Pimsner, July 7, 1936); 2,284,229 (G. V. Palmer, May 28, 1942); 3,062,337 (J. H. Zittle, Nov. 6, 1962); 3,367,076 (P. S. OBrien, Feb. 6, 1968). Such double-skin insulated panels have utilized thermal-insulation materials such as glass fiber batts, lightweight foamed plastic blocks and the like to maintain the inner and outer facing sheets in spacedapart relation. When building panels with spaced-apart facing sheets are applied to a building framework, some fastening means is provided to secure the panel to the structural framework.

The fastening means may be entirely hidden from external view, see US. Pat. 3,372,520 (E. E. Hensel, Mar. 12, 1968). The fastening means may be partly hidden from external view and partly visible, see US. Pat. 3,290,845 (M. K. Snyder, Dec. 13, 1966). The fastening means may be entirely exposed to view, see US. Pats. 3,399,503 (H. J. W. Payne et al., Sept. 3, 1968); 3,466,831 (W. F. Lenoir, Sept. 16, 1969).

The hidden fastening means of Hensel secures only the inner facing sheet to the structural steel. Hensel resorts to a separate channel for positively connecting one edge of the outer facing sheet to the corresponding edge of the inner facing sheet. The Snyder, Payne et al. and Lenoir arrangements provide securement of the outer and inner facing sheets to the structural steel but at the expense of exposed fasteners.

SUMMARY OF THE INVENTION The principal object of this invention is to provide improved fastening means for securing the overlapped edge of a double-skin foam core building panel to a subgirt of a. building framework.

Another object of this invention is to provide improved fastening means by which the outer facing sheet is positively connected to the inner facing sheet, whereby retention of the outer facing sheet is not entirely independent upon auto-adhesive bond between the outer facing sheet and the foam core.

A further object of this invention is to provide improved fastening means by which the inner facing sheet is positive- Patented Feb. 6, 1973 ly secured to the subgirt while the outer facing sheet is positively connected to the inner facing sheet.

The present fastening means is adapted for use with double-skin foam core building panels of the type presenting an inboard side segment along one side adapted for engagement with the structural steel and an inboard side segment along its opposite side. When assembled, adjacent panels are presented in side-by-side, overlapped interfitted relation.

In accordance with the present invention, the inboard side segment of the panel comprises outer and inner longitudinally extending facing sheet portions separated by a foam core. The outer facing sheet portion is provided with an opening. A recess is provided in the foam core beneath the opening. The present fastening means comprises a clip presented in the recess. The clip includes oppositely extending flanges engaged with the exterior face of the outer facing sheet portion and inwardly extending legs engaged with the interior face of the inboard facing sheet portion. Fastening means extending through the clip, secures the inboard side segment of the panel to the structural steel.

The inboard and outboard tfacing sheet portions may comprise segments of the spaced-apart facing sheets. In this instance, the clip and fastener means positively secure the inner facing sheet to the subgirt while the oppositely extending flanges which overlie the outer facing sheet segment, positively connect the outer facing sheet to the inner facing sheet.

Alternatively, the inboard and outboard facing sheet portions may comprise confronting segments of the inner facing sheet. In this instance, the clip and (fastener means positively secure only the inner facing sheet to the structural steel.

In each instance, the clip and fastener are recessed and do not interfere with the erection of an adjacent panel in side-by-side, overlapped, interfitted relation with the previously erected panel.
