Abstract: A series of rectangular roof panels and rectangular wall panels each include inner and outer corrugated sheet metal skins which are rigidly secured by fasteners to opposite sides of formed sheet metal longitudinally extending spacer members rigidly connected by formed sheet metal laterally extending spacer members. The inner skins and spacer members of the roof panels are rigidly connected across a ridge portion to transmit tension forces. The outer skins and spacer members of the roof panels form a pitch of less than twelve degrees and are rigidly connected across the ridge portion for transmitting compression forces.

Abstract: A method of covering a structure with a panel assembly, comprises laying on the structure a first panel which has first and second marginal ridge portions and an attachment flange extending from the first marginal ridge portion and fixing the attachment flange of the first panel to the structure by means of a fastener passing through the attachment flange. A second panel having first and second marginal ridge portions is placed in overlapping relationship over the first panel thereby to conceal by means of the second marginal ridge portion of the second panel the fixing of the attachment flange of the first panel to the structure. Fastening means are passed through the overlapping first and second marginal ridge portions at locations spaced from said structure. The overlapping marginal ridge portions are then connected together by using the fastening means.

Abstract: After priming the purlins of a post frame building with a blend of rubbery block copolymer and compatible tackifier resin, double-coated foam-backed pressure-sensitive adhesive tape is applied to the primed surfaces to secure the roof panels, which pressure-sensitive adhesive comprises rubbery block copolymer and compatible tackifier resin.

Abstract: A panel made of sheet metal, synthetic resin, or the like and adapted to be mounted shingle-fashion with a plurality of other such panels to an upright wall is of generally rectangular shape with upper and lower end edges and lateral side edges. Between these edges the panel has when mounted a horizontal bend subdividing it into an upper half and a lower half. In the upper half the panel has an upper central substantially planar region which is surrounded by an upper downwardly U-shaped non-planar attachment portion by means of which the entire panel is secured to the upright wall. The lower half has a lower central substantially planar region which is contiguous at the bend with the upper planar region and generally coplanar therewith in a relaxed unmounted condition of the panel.

Abstract: A series of rectangular roof panels and rectangular wall panels each include inner and outer corrugated sheet metal skins which are rigidly secured by fasteners to opposite sides of formed sheet metal longitudinally extending spacer members rigidly connected by formed sheet metal laterally extending spacer members. A formed sheet metal box-type ridge beam and a series of fasteners rigidly connect the inner skins and spacer members of the roof panels on opposite sides of the ridge to transmit tension forces, and a compressive wedge and fasteners rigidly connect the outer skins and spacer members of the roof panels for transmitting compression forces.

Abstract: Corrugated steel plate is formed from a flat plate stock and has a length of at least about 12 feet, a corrugation pitch of at least about 12 inches, and a corrugation depth of at least four inches. The plate has thicknesses of up to one-half inch and more. Also disclosed are structures such as tunnel-type, heavy load-supporting structures defined by upright and horizontal structure portions which extend over no more than about 180.degree. while being capable of supporting up to 40 feet of ground fill and payload thereon. The corrugated plate can be used singly or as double, spaced-apart plate assemblies which are hollow or filled with concrete or a like material, including steel reinforcing bars for the concrete. The corrugated plate can also be formed into vertical, sectional retaining walls, bin type retaining walls, bridge abuttment walls, flat support surfaces such as bridge decking, open air structures, guard rails, sheet piling, etc.

Abstract: A building panel has first and second opposed marginal ridges. The first of the marginal ridges is provided with an attachment zone whereby the panel is attachable to a building structure by at least one fastener. The second marginal ridge is of different cross-section but partly complementary to the first marginal ridge and can be laid in overlapping relationship over a first marginal ridge of an identical panel already attached to a building structure. The second marginal ridge then covers and conceals the attachment of the identical panel to the building structure.

Abstract: A two-piece interlocking siding or roofing slat assembly for covering a surface of a building. The slat assembly includes a central panel having a lower anchoring configuration and an upper hook-like slide configuration integral therewith. A separate attachement strip is provided for securing the panel to the building surface to be covered so as to prevent "oil canning" which is caused by the expansion and contraction of the exposed surfaces. The attachment strip includes a nailing tab adapted to be fixedly secured to the surface of the building to be covered by fastening elements.

Abstract: An element for sealing end voids of corrugated roof panels. The element is shaped and sized to correspond to the shape and size of the corrugated panel end void, and comprises a flexible body having a flange thereon. The flange is grooved for mastic application. An alignment prong cooperates with alignment means in a building structural element so that the element is properly oriented in the end void, and stiffening ribs produce the desired amount of rigidity for the element.

Abstract: A building sheet suitable for roofing and siding use that accommodates fastening along ribs or valleys of a side lapped juncture between two sheets. Strengthening ribs formed from bends in the sheet are shaped to promote stacking, to consume little of the sheet width, and to avoid sharp bends that crack protective coatings. An anti-siphon gap is provided between each lapped and lapping rib, extending the full height of the lapped rib adjacent the lapping edge. A drain trough formed at the base of the gap carries away any water that leaks beneath the overlapping sheet. Low ribs delineate channels in which fasteners can be driven to engage an underlapped edge at a side lap juncture between sheets. A top flat surface of high ribs is narrow enough for stiffness to inhibit deformation by fasteners and restricts the fasteners to locations that avoid drain penetration at side laps.

Abstract: A corrugated wall system formed of prefabricated individual wall sections. Each individual section comprises a member - formed of reinforced concrete or the like -- having front and rear portions spaced by a dimension of corrugation. Both the thicknesses of the front and rear portions, and the dimension of corrugation increase as one moves from the top or a wall section to the bottom thereof. The wall sections are embedded in an in-situ cast foundation in side-to-side relationship at the bottoms thereof.

Abstract: A sheet metal structure having two panels of substantially the same cross section connected to one another by a lap joint at their outer ends. Each panel has at least one major U-shaped section which has a base wall and a pair of oppositely disposed side walls. The base wall is formed with a plurality of minor U-shaped longitudinally extending ribs which form a plurality of alternately disposed minor crests and velleys. The major U-shaped sections and the minor ribs of the panels nest with one another at the lap joint. A spacer panel is provided for spacing the nesting ends from one another to facilitate the rigid securing of the ends. The spacer panel has a body portion formed with a plurality of spacer lugs at one edge thereof which project outwardly from the body portion in a spaced relationship. The lugs have a thickness substantially equal to the thickness of the panels which are to be joined.
