Title: Reconstituted wood block modular building system

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a building system. More particularly, the present invention relates to a reconstituted wood block modular building system. 
     At present many families are unable to purchase decent affordable housing as a result of high costs, mortgage requirements, and allied expenses. Rents have accelerated to a point where the larger part of meager incomes is consumed for shelter. Consequently, it is most apparent that a definite need exists for a building product that would contain and embrace many of the features now found in conventional wood frames homes, i.e. &#34;stick built,&#34; and provide secure and adequate shelter at an affordable price. 
     There has been many attempts in the past to alleviate the housing situation through the development and refinement of wood frame homes, masonry homes, concrete block homes, log homes, mobile homes, etc., but all have had certain drawbacks. The problems usually were associated with the cost involved, livability, durability, and/or the difficulty encountered with erection. 
     The construction of homes has changed very little in the last hundred years. New products have been produced, lumber and labor are still the main ingredient. With the virgin wood forest rapidly dwindling away, however, lumber has become very costly. Skilled labor is very expensive 
     Numerous innovations for composite wood structures have been provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention in that they do not teach a reconstituted wood block modular building system. 
     FOR EXAMPLE, U.S. Pat. No. 4,195,019 to Babina et al. teaches a compression-molding composition containing 95 to 98 parts by weight of a product resulting from the treatment of crushed wood with an aqueous solution of phenol and formaldehyde at the boiling temperature of the solution in the presence of hydrochloric acid at a weight ratio between phenol formaldehyde, water, hydrochloric acid and crushed wood equal to 0.15-0.40:0.048-0.27:10-15:0.07-24-0.1086:1, respectively, 1 to 3 parts by weight of a curing agent, viz, hexamethylenetetramine, 0.5 to 1 part by weight of a curing accelerator such as calcium oxide or magnesium oxide, and 0.5 to 1.0 part by weight of a lubricant such as stearing, oleic acid or stearates. The compression-molding composition has an increased water-resistance (its water-absorption is at most 42-82 mg), a high curing rate (0.57-0.8 min/mm), elevated Martens yield temperature (up to 146 degrees C.) thus making it possible to widen the field of application of the compression-molding composition. A method for preparing the compression-molding composition comprises agitation of the components simultaneously with disintegration thereof at a temperature of 97-99 degrees C. to the content of volatile compounds of from 6 to 10% by weight. The method is simple in implementation, it has a reduced number of technological steps and lowered power- and labor-consumption in the manufacture of a compression-molding composition. 
     ANOTHER EXAMPLE, U.S. Pat. No. 5,246,652 to Hsu et al. teach a method of producing a wood composite treated with a soluble boron compound. Either a phenol-formaldehyde resole or novolac type resin can be used as the binder for a wood furnish. The wood furnish is surface treated with either the resole type resin or novolac resin together with a water soluble boron compound whereafter the surface treated wood furnish is formed into a mat and then consolidated in a press. When novolac is used as the resin, the consolidation takes place under sufficient pressure, heat and time in order to cure the novolac type resin and to form the wood composite. Optionally, the curing of the novolac resin can be promoted by injecting the compressed mat with steam, rather than by means of heated press platens. If a resole type resin is employed as the binder while in its consolidated condition, however, pressurized steam is injected into the consolidated mat for a time sufficient to cure the binder and form the composite. The wood composite so produced and which contains the soluble boron compound, exhibits acceptable internal bond strength, and as a result of the inclusion of the boron compound, renders the composite less susceptible to biological attack and more fire retardant than conventional composites employing phenol-formaldehyde alone as the thermosetting adhesive. 
     STILL ANOTHER EXAMPLE, U.S. Pat. No. 5,365,714 to Potvin teaches a wall for a rampart or building, consisting of a plurality of building blocks, each comprising slightly compacted sawdust or wood chips glued with resin. The building blocks are interconnected by a number of assembling pins and by recesses integral to the respective blocks, so as to frictionally engage into one another. There are also provided full length projections and corresponding grooves of the respective blocks for the same purposes. The thus erected structure is remarkable by the quality of the joints and by the ease and quickness of its assembly or disassembly. 
     FINALLY, YET ANOTHER EXAMPLE, U.S. Pat. No. 5,439,749 to Klasell et al. teach a composite wood structure including first and second spaced layers, and a core interposed between the layers. A sheet-like vapor barrier is between the layers and limits migration of moisture through the barrier to less than about 6 grams per square meter of barrier area per hour. The wood structure is thereby made warp-resistant. In another embodiment, the structure has a vapor barrier on an outer surface and may have one or more additional vapor barriers between structure layers. Preferred vapor barrier materials include melamine formaldehyde impregnated paper, phenol formaldehyde impregnated paper, thermoset materials, thermoplastic materials and aluminum foil. 
     It is apparent that numerous innovations for composite wood structures have been provided in the prior art that are adapted to be used. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, however, they would not be suitable for the purposes of the present invention as heretofore described.

     The configuration of a typical exterior block of the plurality of exterior blocks 16 can best be seen in FIGS. 2 and 3, which are a diagrammatic perspective view of a typical exterior block generally enclosed by the dotted ellipse identified by arrow 2 in FIG. 1, and a cross sectional view taken on line 3--3 in FIG. 2, respectively, and as such will be discussed with reference thereto. 
     The typical block of the plurality of exterior blocks 16 is an exterior block rectangular-parallelepiped-shaped block 20 that has an exterior block flat and rectangular-shaped top face 22, an exterior block flat and rectangular-shaped bottom face 24 that is below, and parallel to, the exterior block flat and rectangular-shaped top face 22 of the exterior block rectangular-parallelepiped-shaped block 20, an exterior block pair of flat, parallel, and opposing end faces 26, and exterior block flat and rectangular-shaped side face 27. 
     The exterior block rectangular-parallelepiped-shaped block 20 is preferably 8&#34; wide, 6&#34; high, 18&#34; long, and weights approximately 22 lbs. 
     The exterior block flat and rectangular-shaped top face 22 of the exterior block rectangular-parallelepiped-shaped block 20 has an exterior block top face longitudinal groove 28 that extends completely horizontally along a longitudinal centerline line thereof, and which is preferably 1&#34; wide and 1/2&#34; deep.

     STEP 2: Add a predetermined amount of a bonding agent to the wood residue in the receptacle to form a first composition wherein the bonding agent is preferably approximately 3 lbs. of phenol formaldehyde which is a phenolic polymer resin sold by Neste Resins Corp. for approximately 18 cents a pound, and which contains no urea formaldehyde and therefore is exempt from all provisions of the HUD Safety Standards which refer to formaldehyde. 
     STEP 3: Add a predetermined amount of wax, for increased mold release characteristics, to the first composition in the receptacle to form a second composition. 
     STEP 4: Mix the second composition thoroughly to form a mixed composition with a density. 
     STEP 5: Monitor the density of the mixed composition carefully as it is being mixed and form a properly mixed composition. 
     STEP 6: Place the properly mixed composition into a properly shaped steel mold. 
     STEP 7: Apply heat and pressure for a specific period of time to cure and bond the properly mixed composition to form the exterior block rectangular-parallelepiped-shaped block 20 wherein the heat can be microwave energy.

     Each key of the plurality of elongated, slender, and rectangular-parallelepiped-shaped horizontal alignment keys 40 is preferably a piece of either lumber or manufactured wood that is 1&#34; wide, 1&#34; high, and 6&#34; long, and is not molded as an integral part of the exterior block rectangular-parallelepiped-shaped block 20 when manufactured, as many of the blocks such as those that encompass door and window units do not require such a joint. 
     The reconstituted wood block modular building system 10 further includes a plurality of elongated, slender, and rectangular-parallelepiped-shaped vertical alignment keys 42. 
     Each key of the plurality of elongated, slender, and rectangular-parallelepiped-shaped vertical alignment keys 42 is disposed in the exterior block top face longitudinal groove 28 in the exterior block flat and rectangular-shaped top face 22 of each exterior block rectangular-parallelepiped-shaped block 20, on both sides of the exterior block cylindrically-shaped throughbore 34, and extends horizontally into the exterior block top face longitudinal groove 28 in the exterior block flat and rectangular-shaped top face 22 in a horizontally adjacent exterior block rectangular-parallelepiped-shaped block 20. 
     The each key of the plurality of elongated, slender, and rectangular-parallelepiped-shaped vertical alignment keys 42 is further disposed in the exterior block bottom face longitudinal groove 32 in the exterior block flat and rectangular-shaped bottom face 24 of a vertically adjacent exterior block rectangular-parallelepiped-shaped block 20, on both sides of the exterior block cylindrically-shaped throughbore 34, and extends horizontally into the exterior block bottom face longitudinal groove 32 in the exterior block flat and rectangular-shaped bottom face 24 of a horizontally adjacent exterior block rectangular-parallelepiped-shaped block 20, and functions as a tongue and groove joint while providing vertical alignment for vertically adjacent blocks of the plurality of blocks. 
     Each key of the plurality of elongated, slender, and rectangular-parallelepiped-shaped vertical alignment keys 42 is preferably a piece of either lumber or manufactured wood that is 1&#34; wide, 1&#34; high, and 1&#39; long, and is not molded as an integral part of the exterior block rectangular-parallelepiped-shaped block 20 when manufactured, as many of the blocks such as those that encompass door and window units do not require such a joint. 
     The reconstituted wood block modular building system 10 further includes a plurality of anchor bolts 44 that are embedded around the perimeter of the concrete slab 14, preferably approximately 6 to 8 feet apart. 
     The reconstituted wood block modular building system 10 further includes a plurality of steel rods 46, each of which being having threaded ends and being preferably 3/8&#34; dia. and 2&#39; long since longer lengths or a single rod would be unwieldy by interfering with placing the blocks. 
     Each rod of the plurality of steel rods 46 is coupled to a respective anchor bolt of the plurality of anchor bolts 44, by a threaded sleeves 48, and passes vertically upwardly through the exterior block cylindrically-shaped throughbore 34 in vertically aligned exterior block rectangular-parallelepiped-shaped blocks 20 so as to provide added strength for the wall 12 to withstand most winds and hurricanes. 
     If required, which usually is the case, additional rods of the plurality of steel rods 46 can be added to subsequent rods of the plurality of steel rods 46, by use of the threaded sleeves 48, as the wall 12 progresses, so as to extend their length to the top of the wall 12. 
     The plurality of stacked exterior blocks 16 and the plurality of stacked corner blocks 18 are glued together with a waterproof type of construction adhesive, which is preferably the type of adhesive presently being used to bond parquet floors to a concrete slab, without the need for mortar. 
     As a result of the rounded edges of the exterior block rectangular-parallelepiped-shaped block 20, the adhesive would form a grout line that provides a finished look for the wall 12. 
     As shown in FIG. 7, which is a diagrammatic partial cutaway side elevational view of the exterior wall of FIG. 1 completed and supporting a roof assembly thereon, a top plate 50, which preferably is either lumber or reconstituted wood, sits on the top course of the blocks, with the plurality of steel rods 46 extending through apertures therein and being tied down with a washer 52 and a nut 54 so as to provide extra protection from high winds, while the top plate 50 also serves as a base for roof trusses 56. 
     It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of constructions differing from the types described above. 
     While the invention has been illustrated and described as embodied in a reconstituted wood block modular building system, however, it is not limited to the details shown, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention. 
     Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute characteristics of the generic or specific aspects of this invention.
