Imperforate Panel With Integral Reinforcing Patents (Class 52/630)
  • Patent number: 5660907
    Abstract: A reinforced structural member comprising a solid structural member of recycled plastic having a reinforcing bar inserted therein, extending inwardly from one surface. A notch is formed in the solid structural member extending inwardly with respect to the surface against which force is to be exerted. An untensioned reinforcing bar formed of a material having characteristics of resilience and compressibility different from that of the structural member is inserted and locked into the notch. The reinforcing bar is complementary in shape to the notch, and is held in place by the density of the solid structural member and fasteners such as screws. In this way, two dissimilar materials, neither of which alone has sufficient strength, rigidity, or "memory" can be combined to create a durable, inexpensive set of components which substantially exceed the mechanical qualities of either material by itself.

    Abstract: A filament wound composite structure, its tooling and method of manufacture. The isogrid filament wound composite structure is formed having at least one or more pseudo-isotropic laminate zones in its joint regions. This structure is realized through the use of specialized tooling. The ribs of the isogrid filament wound composite structure are discontinued by tapering them out into a thin skin. This is accomplished by gradually widening the grooves in the mandrel while simultaneously decreasing the depth of the grooves. This gradual change in the tooling redistributes the material in the ribs into a thin skin. The fibers that are redistributed into this thin layer, coupled with the skin wound over the top of the ribs, provide the necessary reinforcement in the joints.

  • Patent number: 5077949
    Abstract: An architectural cover panel system of individually adaptive panels for covering structural support members of an underlying structure such as girders. An individual adaptive panel includes a sheet of flexible material having a generally convex cross-section and is provided with corrugations oriented perpendicular to the longitudinal axis of the panel. In one preferred embodiment the convex panel is provided with edge portions attached to the lateral sides of the panel. The edge portions are similarly provided with corrugations oriented parallel to and intersecting or merging into the corrugations of the convex panel portion. In other embodiments of the invention, panels having radial corrugations are used allowing the panels to respond to dimensional changes due to temperature effects and to resist wind forces without deforming the shape of the overall structure, and panels with diagonal corrugations provide bidirectional flexibility.

  • Patent number: 5020295
    Abstract: A coated steel roof cladding panel comprises upwardly projecting, inverted channel, edge and stiffening ribs with essentially flat pans between the ribs. At or near each junction of a rib and panel there is a small bead extending in the same direction as the ribs, and projecting downwardly. If the panel is walked upon after or while being laid on supporting purlins, the beads deform sacrifically and prevent unsightly transverse marks forming in the pans due to flexing of the panel.

  • Patent number: 4962622
    Abstract: An improved cold formed, sheet metal profiled building unit and method of making the same are disclosed. The building unit incorporates at least one longitudinal stiffening rib in a longitudinal flat region of the type having a tendency to buckle when subjected to compressive forces. The longitudinal stiffening rib is formed not by drawing-in sheet metal as in current roll forming practices, but, instead, by stretching a segment of the sheet metal. Each longitudinal rib has a profile width, as measured along the centerline of the rib, which is greater than the linear of the sheet metal segment from which it was stretched-in. Roll forming machines incorporating the principles of this invention utilize fewer roll stands than do roll forming machines incorporating the principles of current roll forming practices.

  • Patent number: 4917933
    Abstract: A plastic sheet is disclosed which is used as a subcarrier for insulating linings of building surfaces. The sheet is formed by parallel, alternating, dovetail-shaped channels and grooves. A coarse-meshed lattice matting, having filaments, is glued or partially fused to the backside of the plastic sheet and serves to anchor the sheet to the underlying foundation. This lattice matting stretches over the entire backside or inner surface of the sheet. The webs of the plastic sheet are expandable and can compensate for stresses occurring between the underlying foundation and the external facing material such as ceramic tile.
