Abstract: An arrangement for interconnecting and supporting a pair of hexagonal building structures includes a pair of common support columns each having a hexagonal shaped connector tube mounted to an upper end thereof. Each connector tube includes apertures in each of the six lateral walls thereof which are adapted for receiving a nut and bolt combination for coupling the tube to the eave beams and roof trusses of two hexagonal building structures. The nut and bolt combinations are hidden from view within the connector tube and adjacent beams to provide a clean, attractive appearance and are not exposed to the elements. The use of common support columns and a common eave beam for adjacent hexagonal building structures simplifies assembly, reduces the number of structural components and building cost, and integrates two or more of such building structure for increased structural strength.

Abstract: A structure for a hexagonal building has a novel steel frame including a connection which joins tension ring members, columns and roof trusses together with threaded fasteners. The upper ends of the rafters are joined by a tension ring. The bottom of each column is secured to a base by means of an adjustable base plate. Rafters spanning between the tension ring and compression ring are located between adjacent trusses. The frame is adapted to receive prefabricated sandwich-type panels for both roof and walls.

Abstract: A prefabricated panel of substantially uniform width and thickness and having an interlocking feature comprises a foamed core slab, a rigid facing sheet bonded to the foamed core slab, and flange members integral with the facing sheet which interlock adjacent panels of the same type. Optionally, a heat-reflective liner is provided on the back side of the core slab.

Abstract: A structural panel material of the sandwich-type construction includes inner and outer facings and a core bonded between the facings. The core includes a plurality of blocks of lightweight core material, such as rigid or semi-rigid plastic foam, balsa wood, or a combination of plastic foam. These blocks are arranged in strips. The strips are joined together by corrugated sheet material. In a preferred embodiment, double-sided corrugated paperboard is used to join the lightweight structural strips. The resulting core material has the highly desirable characteristics of being flexible enough to conform to a mold shape under gravity and with the application of little or no external pressure so that special jigs are not required.

Abstract: A roof structure for a building includes a number of panels, preferably of a sandwich construction with a rigid foam core and upper and lower surfaces which may be metal, wood or other material depending upon the use. A first type of joint extends along the fall line of the roof, with the panels being in side-by-side, spaced relation and supported along their ridges by a roof truss extending along this longitudinal joint. A retainer strip extends along the longitudinal joint and is held in sealing relation with the adjacent panels by means of threaded fasteners secured to the truss. A joint transverse of the fall line is formed by a tongue-in-groove construction of the panels which permits an upper panel to lap over a lower panel for better drainage, and also allows for thermal expansion and contraction.

Abstract: Insulating stud members comprising a foamed core having a sheet-form fastening member affixed to one surface and a thin moisture-impervious sheet affixed to the other surface and extending beyond the edges of the core to provide sealing flanges, and assemblies comprising a plurality of abutting insulating panels joined by the stud members, the panels each having a foamed core slab and a rigid facing sheet bonded to the core slab on one side thereof and a recess extending along the free edge of each of the adjacent core slabs, the recesses of adjacent panels cooperating to define a continuous open channel therebetween of dimensions just sufficient to receive a stud member so that the flanges thereof engage the surface of the insulating panels, fastening means extending through the insulating panels and having their ends embedded in the sheet-form fastening members of the stud members, and the sealing flanges being sealed to the surfaces of the insulating panels by means of a sealing material.
