Abstract: A jointing construction for laminated panels of the type having a core lamination of heat insulating material and facing sheet laminations bonded to opposed sides of the core, said joint construction comprising at least one pair of flanges each of which is defined by turning one of a pair of opposed edge portions of one facing sheet outwardly substantially perpendicular to the plane of said sheet, the jointing construction being intended to join a pair of said panels disposed in use such that one flange of one panel is adjacent one flange of the other panel, a joint cap adapted to engage said adjacent flanges, said joint cap including a bridging portion and a pair of spaced side portions each depending from said bridging portion, one side portion of the joint cap being intended to locate adjacent each flange on the side thereof adjacent the inner portion of the panel on which the respective flange is formed, each said side portion being substantially parallel to its adjacent flange, and a water seal fitted be

Abstract: An improved roof structure using flexible sheets of waterproof roofing material such as a felt backed polyvinyl chloride. An inverted generally V-shaped channel joins adjacent edges of the sheets of material. The channels have sides and an apex extending above the normal maximum water level on the roof structure during heavy rains. The adjacent edges of the material are bonded to the opposite sides of the channel and are further sealed by overlapping and bonding together or by a bonding to the inside of a second, overlapping inverted V-shaped channel. The air space in the first generally V-shaped channel may be vented to the atmosphere to prevent sweating beneath the roofing material.

Abstract: A batten, adapted to retain at least one of a pair of juxtaposed, unitary, coextruded solar collector panels to the structural members of a building, the batten having a substantially horizontal retention member, portions of which extend over portions of the top of the adjacent collector panels, and a pair of substantially vertical leg members contacting and depending from the retention member and adapted to retain the adjacent collector panels in juxtaposed position, the batten further allowing for thermal expansion in a lengthwise and crosswise direction, while also reducing bowing of the collector panels from their planar configuration. The batten is capable of unitary formation in lengths sufficient to retain the adjacent collector panels in place along substantially their entire length.

Abstract: A plurality of identical metal roof panels are secured to the roof purlins by spaced metal clips. Each roof panel, which may be installed without regard to end-to-end orientation in its own plane, includes deformable tabs extending outwardly of its side edges. Adjacent roof panels are interlocked with each other by interengagement of the tabs in response to positioning of the panels in place. The clips which secure the roof panels to the purlins are also provided with deformable tabs arranged to interengage with the tabs of the roof panels thereby to hold the roof panels in place even prior to bending of the tabs. The tabs are bent downwardly and a sealing strip is fitted over the bent tabs to weatherproof the seam. The roof is constructed using these panels by proceeding from one end of the building to the other in a single pass.

Abstract: A roof panel that is lightweight and structurally strong, and that can be assembled with other panels to form large area surfaces, comprises a rectangular panel made with an extruded U-shaped channel frame member, that is mitered at the corners. The frame is enclosed by two sheet members that are attached by adhesive bond supplemented by screws or other type fasteners to the outer surface arms of the frame. The base portion of the U-shaped channel member has a flange extension on one side whereby the two edges of two adjacent panels can be bolted together. A resilient sealing gasket is placed between the two flange extensions, of the U member so that as the bolts tighten the two members together, the joint between is sealed by the gasket. After the two panels are joined in this manner, a specially shaped inverted U shaped ridge cover channel is placed over the sealed joint, and is latched into notches, which hold the cover in place.

Abstract: A panel assembly comprised of two or more pre-formed panel members securely joined operatively with each other without utilizing separate fastening means. The panels employed utilize pre-formed snap locking means provided along margins thereof to effect interconnection of adjacent panels to each other or to a pre-formed connecting member interposed therebetween. The panel assembly may be incorporated into roof, ceiling and wall constructions, which may include integral corner joints depending upon structural requirements. Tools to assist in assembling panels into an integral assembly also are disclosed. The procedure of hook and snap-lock assembling a panel structure may be performed by hand; by utilizing the assistance of tools disclosed; or by utilizing other mechanical aids.

Abstract: Composite panels each having a casing and insulating material in the casing are mounted in a covering layer over the inside of a supporting structure by mechanical fastening means. Joint cover members including insulating material and outer facing material are disposed in the spaces between casings of adjacent composite panels. The outer facing material is sealed to front panel portions of the casings to form a primary barrier for cryogenic liquids therewith. An additional secondary barrier may be provided by using composite panels with interior panels in the casings sealed to inner sides thereof and dividing the casings into front and rear compartments, each having insulation therein, and using front and rear joint cover members, the outer facing material of the rear joint cover members being sealed to outer sides of the casings of adjacent composite panels to form a secondary barrier with the interior panels of the composite panels.

Abstract: Connectors and end caps are provided to connect adjacent roof ridge ventilator sections and to close the ends of the assembly. The connectors include a cutout, intermediate wall, an outer jacket and inner sleeve defining slots to receive the ends of adjacent ventilator sections. The end caps include a deflectable wall having a central depression and bulge. An outer end cap jacket and inner end cap sleeve define a channel to receive the end of the ventilator assembly.

Abstract: A roofing system of the batten type using sheet metal components with wooden or metallic batten supports.With the batten supports in place elongated pan sections are laid between the batten supports and secured to the roof by nails or screws at the top or near the top of the adjacent batten supports. Each pan section has a wide flat elongated central region which lies flat on the roof and which is centrally located between two similar upstanding side walls running the full length of the central region and fitting between two successive battens. Each side wall has an inner, downwardly directed double fold running along the side of the adjacent batten support and terminating short of the central region. A batten covering cap having a centrally located top and downwardly directed wings each with an inner upwardly folded edge fitting behind the double fold is positioned in place by sliding it longitudinally over the associated batten support.

Abstract: A frame assembly is disclosed for supporting a panel which together with the frame provides a partition or divider structure. The frame assembly includes a pair of upright frame members of extruded aluminum and a pair of horizontal frame members of extruded aluminum. The upright members are provided with opposed pairs of polygonal openings therethrough, and the horizontal members include a tubular portion complementary in polygonal cross-section and dimension with respect to the openings in the upright members. Expandable fasteners of complementary cross-section are inserted through the openings and expanded to interconnect the horizontal and vertical members. The horizontal members include integral pairs of flanges providing opposed recesses for receiving corresponding edges of a panel supported by the frame assembly.
