BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a prefabricated building assembly for efficient low cost fabrication of exterior walls, interior walls and roofs to form a building assembly.  
         [0003]     2. Description of Related Art  
         [0004]     Many techniques have been utilized to reduce building costs associated with conventional building construction. Normally, conventional building construction involves a labor intensive process where skilled workers and laborers may pour a concrete foundation, assemble a wall and roof stud assembly, attach exterior and interior walls, assemble roof panels, and set and install windows and doors. On many occasions, the construction of the building may involve numerous contractors and subcontractors who are responsible for various stages of construction. Typically, delays ensue and construction costs escalate accordingly.  
         [0005]     One of the existing techniques used to reduce construction costs involves the use of pre-fabricated modular type homes. Typically, modular homes involve the use of panels, which are shipped to a construction site and only require the connection of the pre-fabricated panels in order to construct the building. The use of pre-fabricated panels provides a less expensive and easily assembled building as opposed to the conventional construction methods. One drawback associated with modular buildings, modular homes tend to lack sufficient strength and durability for long-term use. Modular homes also tend to lack the necessary flexibility to accommodate various sizes and styles. Furthermore, some modular systems require the inclusion of traditional construction techniques in order to complete construction, therefore, escalating the reduced costs associated with modular homes.  
         [0006]     U.S. Pat. No. 5,996,296 to Bisbee relates to a structural panels for a pre-fabricated building and a corresponding method that includes a plurality of space tubular steel columns, a pair of tubular steel girts each interconnecting respective ends of the columns and the plurality of space tubular steel cross members arranged in pairs, and connected on opposite sides of the columns in a registry with each other to accommodate various available building materials. The pre-fabricated structural panel of Bisbee addresses some of the strength and durability shortcomings of the prior art, however, the panels may still be costly to assemble and may be somewhat limited in use in regard to design and style.  
         [0007]     U.S. Pat. No. 6,508,043 to Bond, et al. relates to a building construction system that is configured to comprise a modular, transportable construction kit type structure, which can be easily provided to a particular building site and has the capability of being expandable into a variety of different configurations depending upon the particular needs for a particular building. The building construction system of Bond includes vertical frame members that are used in conjunction with a plurality of corrugated material panels and a quantity of concrete. The building construction system of Bond attempts to address the cost and efficient construction associated with building construction. Furthermore, it attempts to provide a more sturdy and durable building than associated with the pre-fabricated modular homes of the prior art. The building construction system of Bond, however, still requires extensive labor, and therefore does not reduce costs sufficiently in order to provide a complete substitute for traditional construction methods.  
         [0008]     Accordingly, a need exists for an improved modular panel assembly system, which truly addresses the shortcomings of the prior art. More specifically, it would be advantageous to have a pre-fabricated building assembly that allows for cost effective building construction, flexibility to accommodate various designs, and sufficient re-enforcement capabilities to provide durable building construction.  
       SUMMARY OF THE INVENTION  
       [0009]     The present invention relates to a prefabricated building assembly capable of providing a swift, efficient and economic construction of exterior walls, interior walls and roofs to form a building assembly. The present invention includes interlocking prefabricated panels that may form a building assembly comprised of exterior walls, interior walls and a roof. The system may be assembled in its entirety, or the wall and roof system may be utilized independently of each other and adapted to include standard building materials (i.e. standard roof trusses, interior framing, exterior block walls).  
         [0010]     The interlocking panels may be constructed primarily of expanded polystyrene components to build exterior walls, interior walls and an interlocking roof system for high insulation benefits and light weight. The wall components may consist of “H” blocks, “corner blocks” and “interlocking panels.” The building panels may be sized differently in length or height to accommodate the specifications of a given plan. Once erected, the walls having vertical voids in the wall system may receive steel rebar, be filled with a cementitious material and/or any other suitable matter. The interlocking roof panels are attached to each other to form a roof assembly and include channels that receive steel rebar and concrete that provide a means to adjoin to the wall assembly thus forming the building assembly. Mechanical and utility chases may be placed within the building assembly panels and standard building materials may be secured to the structure. Once completed, the entire surface area of the panels will be encapsulated with a cementitious mixture that bonds to the surface and enhances the structures impact resistance, rigidity and strength.  
         [0011]     It is therefore an object of the present invention to provide a prefabricated building assembly necessary for construction of a building comprising: a plurality of exterior wall panels; a plurality of exterior connection blocks, the plurality of exterior connection blocks being capable of joining the plurality of exterior wall panels that form an exterior wall of the building; a plurality of roof panels, the plurality of roof panels forming a roof of the building; a plurality of interior wall panels; and a plurality of interior connection blocks where the plurality of interior connection blocks being capable of joining the plurality of interior wall panels that form at least one interior wall of the building.  
         [0012]     It is also another object of the present invention, to provide a prefabricated building assembly necessary for construction of a building which includes exterior wall panels, exterior connection blocks, the exterior connection blocks being made to join the exterior wall panels that form an exterior wall of the building, roof panels that form a roof of the building, interior wall panels, and interior connection blocks capable of joining the interior wall panels that form at least one interior wall of the building. A polymer may be used to form the exterior wall panels, interior wall panels, exterior connection blocks, interior connection blocks and roof panels. A cementitious coating may be applied to the wall panels and connection blocks in order to bond the surface and to enhance the impact resistance, rigidity and strength.  
         [0013]     In accordance with these and other objects which will become apparent hereinafter, the instant invention will now be described with particular reference to the accompanying drawings.

FIGS. 3G and 3H  show corner blocks that include top portions  32   b ,  32   c  which are pitched to provide the angle to abut roof panels of the complete building assembly.  
         [0088]     The formation of the exterior walls begins with use of the corner block  30   a ,  30   b . The corner block  30   a ,  30   b , exterior H block  20   a ,  20   b  and exterior wall panels  10  are preferably designed to be approximately 8′ in height. However, the height can vary dependent on the particular construction. The exterior H block  20   a ,  20   b  and the corner blocks  30   a ,  30   b  may contain a cylindrical void  31  that is approximately 4″ in diameter that runs the entire height of the block. The cylindrical void diameter can vary. Channels  33   a ,  33   b  are cut into the corner block  30   a ,  30   b  and the exterior H block  20   a ,  20   b  as to directly correlate with the walls direction. The channels  33   a ,  33   b  measuring approximately 3″ in depth and 4″ in width are cut so as not to encroach into the cylindrical void  31  and also run perpendicular to the cylindrical void  31  through the full height of the corner block. The exterior wall panels  10  and connection blocks include the recess  14  within the top portion of the exterior wall panels  10 , where the recess  14  receives steel and/or a cementitious material for connection purposes.  
         [0089]     A bonding adhesive may be placed on a mounting slab, not shown, where the corner block  30   a ,  30   b , H block  20   a ,  20   b  or the exterior wall panels  10  are mounted. The corner block  30   a ,  30   b  may be affixed to the slab by applying the bonding adhesive between the corner block  30   a ,  30   b  and slab, and sliding the corner block  30   a ,  30   b  over an existing rebar that has been secured to the slab.  
         [0090]     Once the corner block  30   a ,  30   b  is in place, an adhesive may be applied to the channel  33   a ,  33   b  of the corner block and applied to the interlocking edge  11   a ,  11   b  of the exterior wall panel  10 . The exterior wall panel  10  is placed upon the adhesive and over any existing mechanical stubouts. The exterior wall panel  10  may receive recesses to accommodate the stubouts. The interlocking edge  11   a ,  11   b  of the exterior wall panel  10  is inserted into the channel  33   a ,  33   b  of the corner block  30   a ,  30   b . The sizes of the exterior wall panels  10  may be fabricated in various spans to accommodate desired specifications.  
         [0091]     Once the exterior wall panel  10  has been interlocked and secured an H block  20   a ,  20   b  is added to the other interlocking edge  11   a ,  11   b  of the exterior wall panel  10 . The interlocking edge  11   a ,  11   b  of the exterior wall panel  10  receives the adhesive and the H block  20   a ,  20   b  is placed over or vertically slide onto the existing steel rebar that is protruding from the slab.
