  • the present invention provides a method of producing a laminate material that is highly durable, aesthetically pleasing, and suitable for construction projects wherein no screws or nails are externally visible.
  • the invention makes use of PNC-based trimboard materials, such as those described above, in their commercially available sizes (i.e., up to 1" thick) to create a multilayer laminate comprised of multiple layers of the trimboard.
  • each layer of trimboard 2 adjacent to another is fastened to the other via one or more of a variety of means.
  • the trimboards may be affixed to one another by conventional nailing and/or screwing.
  • adjacent layers 2 are bonded by construction adhesive or PNC cement, such as commercially available 2P-10TM manufactured by FastCap, LLC (Bellingham, WA), or Gorilla GlueTM (U.S. Pat. No.
  • a fine bead of adhesive 4 is preferentially placed along the center 6 of the planar interface 8 between adjacent trimboards 2, in such a manner as to prevent excess adhesive from seeping out from the layer between any two trimboards.
  • the adhesives are also easily sanded, which may be necessary following a laminate cutting operation.
  • the trimboard surfaces at the laminate interface may be smoothed mechanically or chemically, or otherwise processed, to maximize delamination resistance.
  • a composite laminate structure 10 prepared in accordance with this invention exhibits an increased stiffness and strength in a direction normal to the planar interface between trimboards, as well as an improved resistance to microcracking after a prolonged period of use in the field.
  • the composite structure also generally exhibits increased longitudinal shear strength.
  • the structure also exhibits increased axial load strength proportional to the thickness and number of trimboard layers employed.
  • Figure 2a shows a cross-sectional view of a laminate sheet that has been mitered to exhibit shaped grooves 112. While various shaped grooves (e.g., more curved or displaying more angled features) may be used, the pattern illustrated is particularly useful in allowing a single piece of laminate to be folded into a variety of shapes that exhibit nearly seamless combination. As shown, the grooves 112 do not go all the way through the laminate, but are cut sufficiently deep so as to allow for folding of the laminate sheet. When the sheet is folded, adhesives, glues or epoxies as described above are applied to the contact surfaces 114 to assure mechanical strength.
  • Figures 2b-e illustrate a sample of the structures that can be formed by adjusting the groove angles 116 and spacings 118 between the grooves.
  • Figure 2b illustrates a solid beam formed from the folded sheet.
  • Figure 2c illustrates a hollow variation that may be suitable for use as the support column 30 of the railing system below.
  • Figure 2d illustrates a variation that may be used as a decorative covering to concrete columns in imitation of a Roman style.
  • Each of these shaped components can be made of any desired length, and may be used, for example as a decorative collar-like finish 120 to a post or column 122, such as illustrated in Figure 2e.
  • Figure 3a and Figure 3b show a perspective view of the hollow columns of Figure 2c and Figure 2d, respectively.
  • the composite laminate may then be employed as workable components in a wide range of assemblies.
  • One such assembly, a railing system, is now described with the assistance of Figures 4-9.
  • Figure 4 illustrates a railing assembly 20 and several views of components thereof, including a handrail 22, a baluster rail 21, a plurality of balusters 24, and a bottom rail 23. All components are preferably manufactured from a composite laminate material, and dimensioned to be assembled together tightly.
  • Handrail 22 is beveled to create an ornamental design that also allows a person to comfortably grip the handrail.
  • the handrail is also mitered to form a notch 26 on the underside into which baluster rail 21 will be glued and/or fastened via screws or nails through holes 28 from the bottom of baluster rail 21, which is out of the field of view of a person standing or sitting proximate to the railing assembly 20.
  • Bottom rail 23 has a corresponding notch 27 on its top surface into which one end of each of the plurality of balusters 24 is inserted, thereby receiving alignment and vertical support from the bottom rail 23.
  • the respective other ends of each of the plurality of balusters are secured to the baluster rail 21, preferably by gluing.
  • Figure 5 illustrates an end view of railing assembly 20 wherein the handrail 22 and bottom rail 23 have been optionally reinforced by channels 102 and 104.
  • Channels 102 and 104 are comprised of a rigid, durable material such as, for example, aluminum, that increases the horizontal stability of the handrail and bottom rail.
  • Channels 102 and 104 may comprise a single section or multiple sections of material that run the entire length of the rail or shorter portions thereof where horizontal forces (such as persons leaning against the rail) are of particular concern.
  • the channels 102 and 104 are mateably received by the corresponding notches 26 and 27, respectively.
  • Each contacting flange end point 106 may be fined to assure a tighter mechanical grip, but the primary mechanism for adhering the channels will be fasteners 108 extending through holes (not shown) in the channels into the corresponding rail.
  • the fasteners may be the same fasteners (e.g., screws or bolts) that adhere the railings to the railing posts.
  • FIG. 6 presents a view of support column 30, which provides support for baluster rail 21.
  • support column 30 may be solid or have a wholly or partially hollow core.
  • the support column also has a notch 32, for receiving an end of baluster rail 21.
  • the baluster rail may simply be glued into the notch 32, or additionally (or alternatively) a washer 36 and screw 38 may fasten the baluster rail 21 to the support column 30.
  • the handrail 22 and a top cap 40 would be connected on top of the baluster rail 21 and support column 30.

  • top cap 40 comprises a top cap 40, comprised of top assembly 44 that is secured (preferably by gluing) to a bottom assembly 42, which in turn is fastened (also by gluing) to the top of support column 30.
  • bottom assembly 42 is optionally beveled along edge 46 in such a manner as to allow mating to the beveled surface 28 of top rail 22. This provides a seamless fit and additional interface surface area over which an adhesive may be applied to secure the bottom assembly 42 to handrail 22.
  • bottom assembly 42 includes a notch 48 for integral connection with baluster rail 21.
  • bottom assembly 42 may be hollow to allow access during installation to other components to which the bottom assembly is to be secured.
  • the present invention also provides a reinforcement mechanism 124 that is especially suited, though not limited, to providing reinforcement for support columns having a hollow core (such as column 30) that have been formed of the laminate described above.
  • the reinforcement mechanism comprises a core column 126 of a sturdy material such as, for example, aluminum that has dimensions such that it will fit within the hollow column in close proximity, but not contacting the inner the walls of the hollow column being reinforced.
