Abstract: Wood-based composites, and methods for their manufacture, are provided. The composites include oriented wooden strands and cured bonding resin connecting adjacent strands. The composites are relatively low-density, having an average dry density of the wooden composites of about 15-28 pounds per cubic foot (pcf). The unique composition of the composites provide improved structural and insulating (thermal and acoustic) properties when compared to traditional engineered wood products (e.g., oriented strandboard).

Abstract: The present disclosure provides colored compositions formulated to provide water repellency and crocking resistance when applied as a coating to a surface (e.g., the surface of a wood product). The compositions include a colored pigment, a wax emulsion, a latex polymer, and a halogenated phosphate ester. Wood products treated with the composition, as well as methods for applying the composition to a surface, are also provided.

Abstract: The present disclosure provides formulations that provide fire resistance when applied as a coating to a surface (e.g., the surface of a wood product). The compositions include an isocyanate, a brominated compound that is reactive with the isocyanate to form a polyurethane, an intumescent component, and a fire-retardant synergist. Wood products treated with the composition, as well as methods for applying the composition to a surface, are also provided.

Abstract: A fire-resistant coating for a wood product which includes a polyurethane matrix. The polyurethane matrix includes an aromatic isocyanate which is present in a quantity ranging from 20% to 50% by weight of the formulation, castor oil which is present in a quantity ranging from 10% to 60% by weight of the formulation, intumescent particles, and a fire retardant present in a quantity ranging from 1% to 40% by weight of the formulation. The fire retardant is selected from the group consisting of disodium ocataborate tetrahydrate, Colemanite (CaB3O4(OH)3.H2O), Ulexite (NaCaB5O6(OH)6.5(H2O)), Aluminum trihydrate, Magnesium hydroxide (Mg(OH)2), Hydromagnesite (Mg5(CO3)4(OH)2.4H2O), and Hunitite (Mg3Ca(CO3)4). Fire-resistant wood products incorporating the fire-resistant coating are also described.

Abstract: The disclosure relates to a prefabricated framing member support system and methods for installing such a system with a horizontal framing member, the horizontal framing member having a top chord, a bottom chord, a web connecting the top chord to the bottom chord and a framing member cross sectional end profile. The prefabricated support system includes an integrated rim board component having a substantially L-shaped cross sectional end profile. The integrated rim board component includes a substantially vertical portion and a substantially horizontal portion.

Abstract: A shear brace assembly is provided which laterally braces wall lines within a structure, such as a house or other residential construction, while also providing vertical and out-of-plane load carrying capacity. The assembly consists of one or more wood-based panel(s) which are rigidly connected to concrete, masonry or wood support material directly below or above the shear brace assembly bearing surface. The term “wood-based” should be interpreted to mean that the panel may be constructed from a natural wood, or partially or wholly from an engineered wood, such as Timberstrand®, Parallam®, or the like. Ductile anchorage assemblies are used below, and in some applications, above the individual panels.

Abstract: The present invention is a system of building materials with surface regions destined for joint formation that are treated with an adhesive partially comprised of a mixture of epoxy resin (96.0-99.9 parts) and hardener (4.0-0.1 parts), such that the epoxy resin/hardener mixture constitutes 50-100% of the adhesive. In an alternative embodiment, the adhesive may have epoxy resin (96.0-99.9 parts) such that the epoxy resin constitutes 45-95% of the adhesive. The remainder of the adhesive may be one or more of the following: hardeners, plasticizing agents, diluents, thickeners, fillers, colorants, opacifying agents, preservatives, and surfactants.

Abstract: The present invention is a raised floor assembly efficiently connecting a pre-fabricated shear wall to a foundation in applications other than slab-on-grade. The raised floor assembly includes an engineered wood material block machined to accept a connecting rod therethrough. The raised floor assembly also includes a connecting rod that is configured to attach at one end to a pre-fabricated shear wall and is coupled at the other end to an anchor bolt. Additionally, a transfer plate may be positioned between the pre-fabricated shear wall and the top of the engineered wood material block. The transfer plate provides a bearing surface for the pre-fabricated shear wall and helps maintain connecting rod alignment. A transfer plate may also be provided underneath the engineered wood material block and above the foundation. Additionally, a variety of spacers may be provided between the bottom of the engineered wood material block and the foundation.

Abstract: A reinforced wood product and methods for reinforcing a wood product are provided. In a first method of manufacture, one or more cords are placed between a first wood layer and a second wood layer in a continuous length. The cords may be constructed from metal, plastic, rubber, or the like. The wood layers and the cords are compressed to form a floor panel or a wall panel. In a second method of manufacture, one or more cords are applied to separate wood sections of a first wood layer. Separate wood sections of a second wood layer are aligned with the wood sections of the first layer to form lap joints in a staggered formation. The first wood sections, cords and second wood sections are then compressed to form a wood product, such as a wall panel or floor panel.

Abstract: The present invention provides a castellated beam that includes a first beam section that has a cut line pattern defining a plurality of first beam section lands and first beam section grooves. The castellated beam also includes a second beam section, that also has a cut line pattern defining a plurality of second beam section lands and second beam section grooves. As formed, the first beam section lands are connected with the second beam section lands. This castellated beam is constructed from a material that contains wood.
