HOWARD H.NUERNBERGER ATTORNEY 3,%8,573 Patented June 12, 1962 ,038,573 CORRUGATED SHEATHING SYSTEMS Howard H. Nuernberger, Natrona Heights, Pa, assignor to Aluminum Company of America, Pittsburgh, Pa., a corporation of Pennsylvania Filed Aug. 14, 1959, Ser. No. 833,730 2 Claims. (Cl. 18988) This invention relates in general to sheathed structures and is more specifically addressed to an improved sysincluding the walls and roofs of buildings, in which conventional corrugated sheet members are secured to 'an underlying supporting structure without the necessity of providing special and expensive retaining clips and like fastening elements.

same which can be installed from the exterior surface of the underlying structure supporting the same.

Other objects and advantages of the invention will be fully understood on reference to, and consideration of,

ard sizes, any one of a number conventional blind rivets, nails or similar [fastening devices, represent the material requirements in the successful practice of the invention.

Referring to the drawings, for a practical illustration of the invention, 10 represent elements of a structure Studs, rafters, girts, purlins, or similar framing members employed in building construction, satisfy the requirement and conditions fulfilled by the elements l, their chief purpose lacing to erve as underlying structure or support for sheathing in the form of corrugated sheets 12.

In the preferred practice of the invention, a retaining strip 14, preferably obtained by shearing a narrow strip from an end of a full sheet 12 across its width transverse to the corrugations, is secured to an exposed surface of each of the members 10. In the case of Wood construction, the strip 14 can be nailed directly to members 10, at suitable intervals along its length, with the nails 16 driven through the troughs of the corrugated retaining In the case of metallic, or other materials more durable and permanent than wood, for the underlying supporting elements 10, metal screws, rivets, lag bolts, and similar conventional fasteners would be substituted for the nails 16.

The cover sheets L2 are supported on the retaining strips '14 in nested relationship of their complementary corrugations, and suitable rfastening devices, such as conunderlying corrugated retaining strips 14 with the corrugations of the sheets I2 in nested relationship within the corrugations of the retaining strip '14, the latter strip or strips being, in turn, secured to a permanent framing or supporting structure represented 'by the elements 10. It will also be mam the invention permits securement of the sheathing sheets of the rivets 20 to act as a seal against moisture through the adjacent connections. The material of the washer would preferably be natural or synthetic rubber or a soft metal such as lead.

Although a single embodiment has been selected for the corrugated covering sheets and complementary retaining strips may be resorted to without departing from the intended scope and spirit of the invention, as hereinaiter claimed.

Having described the invention, what is claimed is:

1. A sheathed installation comprising a rigid underlying supporting structure composed of parallel spaced framing members, corrugated sheathing sheets of identical configuration in respect of their corrugations in a transverse from at least one of the corrugated sheets transversely through the corrugations thereof and secured to coplanarly disposed flat surfaces of the parallel spaced framing members of the supporting passing through troughs of the retaining strips and entering the afioresaid flat surfaces of the framing members of the supporting structure in contact with the underside of the troughs, the secured retaining strips constituting uniform directional disposition, alignment and configuration of their corrugations with the through clearance between the flat coplanar surfaces of the corrugations, the sheathing nested registration of their corrugations with the corrugations of the underlying secured retaining strips, headed fasteners inserted through aligned apertures in nested be-ing manipulated from the exposed surfaces of the crests of the sheathing sheets to upset extending free ends thereof within the clearance spaces formed between the underlying supporting structure and crests of the retaining strips to provide a unitary sheathed installation.

2. A sheathed structure comprising a plurality of parallel spaced members constituting an underlying supportin structure to be sheathed, said spaced members presenting fiat surfaces lying in the same plane, an identical retaining strip secured to the coplanar flat surfaces of each of the spaced members, each retaining strip being of corrugated configuration with the corrugations thereof in alignment and its securing means confined to passing through troughs of corrugations of the strip in bearing contact on the coplanar fiat surface of its supporting member, the crests of each retaining strip so secured providing through clearance in the "axial direction of the corrugations between the crests and plane flat surface of the supporting member underlying the same, a covering sheet having corrugations complementary to the retaining strips disposed in nested relationship thereover, fasteners inserted through aligned apertures in nested crests of the complementary corrugations of the covering sheet and retaining strips from the exposed surface of the covering sheet, and said fasteners being manipulated from the exposed surface of the covering sheet to upset the ends thereof beneath the crests of the retaining strips.
