DETAILED SPECIFICATION

(50) Referring to FIGS. 1-7, the double U-shaped design of the thermal break wood support column (or header) 10 with mechanical fasteners 40 of the invention may be seen and is generally used as an exterior or interior wall support buttress, header or column 10. The double U design (double half box) 10 comprises an inner U section 12 that has two side panels 14 and 16 and a rear panel 18. The panels are held together by an overlapping tab and cut out (box joint) 28 that are fastened together suitably with glue 30 illustrated in FIGS. 5A. 5B and 5C. The double U design 10 also comprises an outer U section 32 that has two side panels 34 and 36 and a rear panel 38. The panels 14, 16, 18, 34, 36 and 38 are held together by an overlapping tab and cut out (box joint) 28 arrangement that are secured together suitably with glue 30 illustrated in FIGS. 5A. 5B and 5C. Suitable wood glues 30 might be polymethylene polyphenyl isocyanate or penta-NA diethylenetriamine pentaacetate obtainable from Ashland of Columbus, Ohio sold under the trademark ISOSET™ or a two part acrylic-based emulsion polymer isocyanate so under the trademark ADVANTAGE EP-950 ATM by Franklin International of 2020 Bruck Street, Columbus, Ohio 43207 USA.

(51) One can size and place tabs and cut outs 28 so support column 10 has only one way to be put together as all square reference surfaces are built-in. Thus, this two dimensional all edge-face assembly is fool proof and easy to form and assemble.

(52) Wood is defined as any wood or lumber product and any wood derivative composite product. Whereby the definition of “wood derivative” is defined as a “New product that results from modifying an existing product, and which has different properties than those of the product it is derived from.” Lumber, timber, wood, or wood derivative, includes any and all structural composite lumber products, such as laminated strand lumber (LSL). This would also include structural composite lumber (SCL), which includes laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL), oriented strand lumber (OSL) and cross-laminated lumber (CTL). Nanocellulose materials, such as cellulose nanocrystals (CNC), would be included in this group. These composite lumbers are of a family of engineered wood products created by layering dried and graded wood veneers, strands or flakes with moisture resistant adhesive into blocks of material known as billets, which are subsequently re-sawn into specified sizes. In SCL billets, the grain of each layer of veneer or flakes runs primarily in the same direction. The resulting products out-perform conventional lumber when either face or edge-loaded. SCL is a solid, highly predictable, and uniform engineered wood product that is sawn to consistent sizes and is virtually free from warping and splitting.

(53) Mechanical fasters 40 are suitably hard wood dowels 40 approximately 11/16-1½ ″ in diameter to match holes H through the panels 14, 16, 18, 34, 36 and 38. The dowels 40 are run through an abrader device to create a helical outer grooved or fluted outer surface 44 which aids in retaining glue 30 on the outer surface 44 of dowels 40. Panels 14, 16, 18, 34, 36 and 38 suitably have angled holes H drilled through them as shown in FIGS. 6 and 7. The holes H in the longitudinal direction have an angles that range from 20°-50° (preferably 38°) and 0°-10° (preferably 8°) in the width direction. Next, wood glue 30 is suitably then coated on the inside surfaces of the angled holes H. The dowels 40 are then pounded into and through holes H after which sawing, sanding or grinding will make the dowels 40 flush with the outer wood panels 34, 36 and 38. Mechanical fasteners 40 may also be made of heat resistant plastic. The important consideration is that the dowel 40 must have a high modulus of elasticity. When using parallel panels 14, 16, 18, 34, 36 and 38, two of the mechanical fasteners or dowels 40 are used per foot of column 20. When using 90° angled panels, discussed below, four staggered and angled mechanical fasteners 40 are used per foot of column 10.

(54) Next the assembled wood column 10 is coated with a liquid wood protection system that is warranted for fire (class A), mould, rot, and insect infestation, including termites. The wood protection system can be applied to the wood column 10 in the following manners: spray booth, flood coater, dip tank, sprayer, brush, roller or pressure treatment. Such a wood protection system is sold under the trademark NEXGEN ADVANCED™ by NexGen ECOatings, Inc. of Vancouver, BC, Canada

(55) This double U wall wood column design 10 may be built, as shown to be a double U design 10, to be a triple 46, quad 48, five 50 or six 52 wall U Shape design, illustratively shown in FIGS. 1B, 1C and 1D. These designs are structurally desirable from 10′ to as high as 40′ tall with little to no deflection. This design will easily hold 25,000 lbs. Additional larger sizes should be anticipated.

(56) The final foam section 39 may be of expanded polyurethane, polystyrene or polyisocyanurate. The foam 39 is injected into the open spaces around the mechanical fasteners 40 and between the wood panel sections 34, 36 and 38. The foam 39 may suitably made by mixing an isocyanate, such as methylene diphenyl diisocyanate (MDI) with a polyol blend, or other suitable rigid foam sheet or there equivalent. Such foams are sold under the trademark AUTOFROTH® sold by BASF Corporation of 100 Park Avenue Florham Park, N.J. 07932 USA and under the trademark PROTECH™ by Carpenter Co. of 5016 Monument Ave. Richmond, Va. 23230 USA In fact, it is to be anticipated that rigid foams of yet even high R values are on the market now with more being created that are and will be suitable for use with the present invention. Polyurethane insulation has the highest thermal resistance (R-values) at a given thickness and lowest thermal conductivity.

(57) The following Table 2 shows R values and vertical compression strength (F.sub.c) of the double U-shaped (double half box) 10, triple U-shaped design (triple half box) 46 and the quad U-shaped (quad half box) 48 wherein the loads are supported on the ends of the pieces:

(59) Referring next to FIGS. 8-17, the quad-shaped 90° or L shaped design of the thermal break wood support column (or header) 60 with mechanical fasteners 40 of the invention may be seen and is generally used as an exterior or interior corner wall support column 10. The quad L design 60 (corner) comprises an inner smallest section 62 that has two side panels 64 and 66. The panels are held together by an overlapping tab and cut out (box joint) 28 that are fastened together suitably with glue 30 illustrated in FIGS. 5A. 5B and 5C. Increasing size are second L section 68, third L section 70 and fourth largest L section 72 and similarly made panels.

(60) As previously stated one can size and place tabs and cut outs 28 so support column 60 has only one way to be put together as all square reference surfaces are built-in. Thus this two dimensional all edge-face assembly is also fool proof and easy to form and assemble. Alternatively as shown in FIGS. 9, 12 and 13, the boards side edges can be mitered and glued at their meeting joints.

(61) Mechanical fasters 40 are suitably hard wood dowels 40 approximately 11/16-1½″ in diameter to match holes H through the panels. The dowels 40 are run through an abrader device to create a helical outer grooved or fluted outer surface 44 which aids in retaining glue 30 on the outer surface 44 of dowels 40. Panels suitably have angled holes H drilled through them as shown in FIGS. 6 and 7. The holes H in the longitudinal direction have an angles that range from 20°-50° (preferably 38°) and 0°-10° (preferably 8°) in the width direction. Next, wood glue 30 is suitably then coated on the inside surfaces of the angled holes H. The dowels 40 are then pounded into and through holes H after which sawing, sanding or grinding will make the dowels 40 flush with the outer wood section. Mechanical fasteners 40 may also be made of heat resistant plastic. The important consideration is that the dowel 40 must have a high modulus of elasticity. When using 90° angled panels, four staggered and angled mechanical fasteners 40 are used per foot of column 60.

(62) Next the assembled wood column 10 is coated with a liquid wood protection system, discussed above, that is warranted for fire (class A), mould, rot, and insect infestation, including termites.

(63) The final foam section 84 may be of expanded polyurethane, polystyrene or polyisocyanurate. The foam 84 is injected into the open spaces around the mechanical fasteners 40 and between the wood panels. The foam 84 may suitably made by mixing an isocyanate, such as methylene diphenyl diisocyanate (MDI) with a polyol blend, or other suitable rigid foam sheet or there equivalent.

(64) This quad L column design 60 may be built, as shown to be a double L design 76, to be a triple 78, quad 60, five 80 or six 82 L Shape design, illustratively shown in FIGS. 8A, 8b, 8C and 8D. These designs are structurally desirable from 25′ to as high as 40′ tall with little to no deflection. This design will easily hold 45,000 lbs with no wind load deflection. Additional larger sizes should be anticipated.

(67) Referring next to FIGS. 18-23, the triple square design of the thermal break wood support column (or header) 90 with mechanical fasteners 40 of the invention may be seen and is generally used as an exterior wall or interior support buttress 90. The triple square design 90 (box) comprises an inner smallest square section 92 that has four side panels 94, 96, 98 and 100. The panels are held together by an overlapping tab and cut out (box joint) 28 or a mitered joint that are fastened together suitably with glue 30 illustrated in FIGS. 5A. 5B and 5C. Increasing in size are middle square section 102 and outer largest square section 104 all with similarly made panels.

(68) As previously stated one can size and place tabs and cut outs 28 (box joints vs. mitered joints) so support column 90 has only one way to be put together as all square reference surfaces are built-in. Thus this two dimensional all edge-face assembly is also fool proof and easy to form and assemble.

(69) Mechanical fasters 40 are suitably hard wood dowels 40 approximately 11/16-1½ ″ in diameter to match holes H through the panels. The dowels 40 are run through an abrader device to create a helical outer grooved or fluted outer surface 44 which aids in retaining glue 30 on the outer surface 44 of dowels 40. Panels suitably have angled holes H drilled through them as shown in FIGS. 6 and 7. The holes H in the longitudinal direction have an angles that range from 20°-50° (preferably 38°) and 0°-10° (preferably 8°) in the width direction. Next, wood glue 30 is suitably then coated on the inside surfaces of the angled holes H. The dowels 40 are then pounded into and through holes H after which sawing, sanding or grinding will make the dowels 40 flush with the outer wood section 104. Mechanical fasteners 40 may also be made of heat resistant plastic. The important consideration is that the dowel 40 must have a high modulus of elasticity. When using 90° angled panels, four staggered and angled mechanical fasteners 40 are used per foot of column 60.

(70) Next the assembled wood column 90 is coated with a liquid wood protection system, discussed above, that is warranted for fire (class A), mould, rot, and insect infestation, including termites.

(71) The final foam section 110 may be of expanded polyurethane, polystyrene or polyisocyanurate. The foam 110 is injected into the open spaces around the mechanical fasteners 40 and between the wood panels. The foam 110 may suitably made by mixing an isocyanate, such as methylene diphenyl diisocyanate (MDI) with a polyol blend, or other suitable rigid foam or their equivalent.

(72) This square column design 90 may be built, as shown to be a double square design 106, to be a triple 90 or quad 108 square shape design, illustratively shown in FIGS. 18A, 18b, 18C and 18D. These designs are structurally desirable from 25′ to as high as 40′ tall with little to no deflection. This design will easily hold 45,000 to 90,000 lbs with no wind load deflection. Additional larger sizes should be anticipated to include quintuplet and sextuplet square designs.

(75) Referring next to FIGS. 24-28, the quad parallel design of the thermal break wood support column (or header) 120 with mechanical fasteners 40 of the invention may be seen and is generally used as an exterior wall support column, interior support column or a header 120. The quad parallel design 120 comprises like inner panel sections 122, 124 and outer panel section 126, 128. Mitered joints or overlapping tab and cut out (box joint) 28 are not needed with this embodiment.

(76) Mechanical fasters 40 are suitably hard wood dowels 40 approximately 11/16-1½″ in diameter to match holes H through the panels. The dowels 40 are run through an abrader device to create a helical outer grooved or fluted outer surface 44 which aids in retaining glue 30 on the outer surface 44 of dowels 40. Panels suitably have angled holes H drilled through them as shown in FIGS. 6 and 7. The holes H in the longitudinal direction have an angles that range from 20°-50° and 0°-10° in the width direction. Next, wood glue 30 is suitably then coated on the inside surfaces of the angled holes H. The dowels 40 are then pounded into and through holes H after which sawing, sanding or grinding will make the dowels 40 flush with the outer wood section 126, 128. Mechanical fasteners 40 may also be made of heat resistant plastic. The important consideration is that the dowel 40 must have a high modulus of elasticity. When using parallel panel sections, two staggered and angled mechanical fasteners 40 are used per foot of column 120.

(77) Next the assembled wood column 120 is coated with a liquid wood protection system, discussed above, that is warranted for fire (class A), mould, rot, and insect infestation, including termites.

(78) The final foam section 136 may be of expanded polyurethane, polystyrene or polyisocyanurate. The foam 136 is injected into the open spaces around the mechanical fasteners 40 and between the wood panels. The foam 136 may suitably made by mixing an isocyanate, such as methylene diphenyl diisocyanate (MDI) with a polyol blend, or other suitable rigid foam or their equivalent.

(79) This parallel column design 120 may be built, as shown to be a triple parallel design 130, to be a five parallel design 132 or a six parallel design 136, illustratively shown in FIGS. 25A, 25B, 25C and 25D. These designs are structurally desirable from 25′ to as high as 40′ tall with little to no deflection. This design will easily hold 45,000 to 90,000 lbs with no wind load deflection. Additional larger sizes should be anticipated.

(80) The following table 5 shows R values and vertical compression strength (F.sub.c) of the triple parallel (stacked) 106, quad parallel (stacked) 120, 5 or quintuple parallel (stacked) 132 and the 6 or sextuple parallel (stacked) 134 wherein the loads are supported on the ends of the pieces:

(82) Wind loads are also a very important consideration. The U-shaped, L-shaped, square-shaped and parallel-shaped triple and quad designs of the thermal break wood support columns, 46, 48, 78, 60, 90, 108, 130 and 120 respectively, where high wind storms and hurricanes put severe horizontal forces on buildings, stand up nicely to these forces as shown below:

(86) Referring to FIGS. 29-32, U-shaped, L-shaped, square-shaped and parallel-shaped designs of the thermal break wood support columns, 10, 60, 90 and 120 respectively, may be seen as illustratively anticipated to be used. The columns suitable may be in an outer building wall as well as within the interior of the building. Suitably, a LVL top plate or bottom plate 140 is placed between the floor and a header like parallel shaped wood support column 120 before it is securely mounted to the particular column 10, 60 and 90.

(87) Referring to FIG. 33, an illustrated twenty story building is illustrated and all its vertical supports are various sizes of thermal break wood support columns, 10, 60, 90 and 120 except the top floors may use vertical supports of the type shown in Applicant's previous two issued U.S. Pat. Nos. 9,677,264 and 9,783,985 for thermal break wood studs (Tstuds®).
