FIELD OF THE INVENTION
The present invention relates generally to a structural insulated panel. More specifically, the present invention is a high impact and load bearing structural insulated building panel that is used for constructing interior walls, exterior walls, floors, and roofs of a building structure.
BACKGROUND OF THE INVENTION
Structural insulated panels are composite building material of an insulating layer of rigid polymer foam sandwiched between two layers of structural board. These structural boards can be consist of material such as sheet metal, plywood, particle board, etc while the insulating layer of rigid polymer foam is commonly expanded polystyrene foam, extruded polystyrene foam, polyisocyanurate foam, or polyurethane foam. The structural insulated panels can be used within many different construction applications, such as exterior walls, interior walls, roofs, floors, and foundation systems since the structural insulated panels combine the functionality of the conventional building components, such as studs, joists, insulation, vapor barrio, and air barrier. The main drawback of the structural insulated panels is that the conventional structural boards used within the structural insulated panels creep and deformed overtime due to load bearings and environmental conditions, resulting structural failure within the overall building.
It is therefore an object of the present invention to provide a load bearing and high impact insulating building panel that utilizes magnesium oxide boards bonded to a high density expanded polystyrene foam core. Due to the components and their configurations, the present invention provides an improved structural insulated panel that has superior impact and fire resistance compare to any other conventional structural insulated panel.

DETAIL DESCRIPTIONS OF THE INVENTION
All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.
The present invention is a high impact and load bearing building panel 1 that replaces the conventional structural insulated panel in the building constructions. The present invention is used for constructing of the exterior walls, interior walls, roofs, floors, and foundation systems of a building structure. The present invention comprises a first magnesium oxide board 11, a phenolic resin sheet 12, an expanded polystyrene layer 13, and a second magnesium oxide board 14.
In reference to FIG. 1-FIG. 3, the phenolic resin sheet 12 is adjacently laminated with the expanded polystyrene layer 13 as the phenolic resin sheet 12 improves the fire resistance within the present invention while providing superior impact absorbance to the present invention. The phenolic resin sheet 12 is a lightweight, chemical resistance, and easy to field fabricate material, wherein those materialistic properties of the phenolic resin sheet 12 improve the overall functionality of the present invention. The expanded polystyrene layer 13 is a thermoplastic, closed-cell, lightweight, and rigid-foam material, where the expanded polystyrene layer 13 provides low thermal conductivity, high compressive strength, and shock absorbing properties to the present invention.
In reference to FIG. 1-FIG. 3, the first magnesium oxide board 11 and the second magnesium oxide board 14 function as the exterior panels of the present invention. More specifically, the first magnesium oxide board 11 is adjacently laminated to the phenolic resin sheet 12 in such way that the first magnesium oxide board 11 is oppositely positioned from the expanded polystyrene layer 13. The second magnesium oxide board 14 is adjacently laminated to the expanded polystyrene layer 13, where the second magnesium oxide board 14 is oppositely positioned from the phenolic resin sheet 12. The first magnesium oxide board 11 and the second magnesium oxide board 14 provide high strength, fire resistance, mold and mildew control, and sound control functionality to the present invention. In reference to general structural construction, the first magnesium oxide board 11 is generally considered as the exterior side of the structural building while the second magnesium oxide board 14 is generally considered as the interior side of the structural building.
Since the first magnesium oxide board 11 and the phenolic resin sheet 12 are laminated to each other, the phenolic resin sheet 12 converts the brittleness of the first magnesium oxide board 11 into high impact panel so that the present invention is able to withstand high impact forces and high stress forces. In other words, the first magnesium oxide board 11 and the phenolic resin sheet 12 form a non-brittle outer layer within the present invention. The phenolic resin sheet 12 also acts as a backing for the present invention, where the phenolic resin sheet 12 achieve low screw pull out within the present invention.
Even though the preferred embodiment of the present invention uses laminating connection method, the present invention can utilize any type of connection methods or any type adhesive materials, such as high pressure bonding, mechanical fasteners, and adhesive, to laminate the first magnesium oxide board 11, the phenolic resin sheet 12, the expanded polystyrene layer 13, and the second magnesium oxide board 14 together. Once the first magnesium oxide board 11, the phenolic resin sheet 12, the expanded polystyrene layer 13, and the second magnesium oxide board 14 are securely laminated to each other, the first magnesium oxide board 11, the phenolic resin sheet 12, the expanded polystyrene layer 13, and the second magnesium oxide board 14 function as a single rigid panel.
In reference to FIG. 1-FIG. 3, the first magnesium oxide board 11, the phenolic resin sheet 12, the expanded polystyrene layer 13, and the second magnesium oxide board 14 each comprise a first edge and a second edge. More specifically, the first edge of the first magnesium oxide board 11, the phenolic resin sheet 12, the expanded polystyrene layer 13, and the second magnesium oxide board 14 are oppositely positioned from the second edge of the first magnesium oxide board 11, the phenolic resin sheet 12, the expanded polystyrene layer 13, and the second magnesium oxide board 14. The first edge of the first magnesium oxide board 11, the phenolic resin sheet 12, the expanded polystyrene layer 13, and the second magnesium oxide board 14 are coincidentally positioned with each other so that the all of the first edges 2 are able to create a flat surface within the present invention. Similarly, the second edge of the first magnesium oxide board 11, the expanded polystyrene layer 13, and the second magnesium oxide board 14 are coincidentally positioned with each other; however, the second edge of the phenolic resin sheet 12 is extended from the second edge of the first magnesium oxide board 11, the expanded polystyrene layer 13, and the second magnesium oxide board 14 so that a connecting seal section can be formed within the present invention.
The present invention further comprises a first spline-receiving groove, a second spline-receiving groove, a third spline-receiving groove, and a fourth spline-receiving groove. The first spline-receiving groove, the second spline-receiving groove, the third spline-receiving groove, and the fourth spline-receiving groove are adjacently positioned with the first edge and the second edge of the present invention. More specifically, the first spline-receiving groove, the second spline-receiving groove, the third spline-receiving groove, and the fourth spline-receiving groove are traversed into the expanded polystyrene layer 13. The first spline-receiving groove and the second spline-receiving groove are adjacently positioned with the first magnesium oxide board 11, where the first spline-receiving groove and the second spline-receiving groove are oppositely positioned from each other and positioned parallel to each other. The third spline-receiving groove and the fourth spline-receiving groove are adjacently positioned with the second magnesium oxide board 14, where the third spline-receiving groove and the fourth spline-receiving groove are oppositely positioned from each other and positioned parallel to each other. Additionally, the first spline-receiving groove and the third spline-receiving groove are coincidentally positioned with each other adjacent to the first edge, and the second spline-receiving groove and the fourth spline-receiving groove are coincidentally positioned with each other adjacent to the second edge.
The attachment between the plurality of high impact and load bearing building panels 1 is explained in relation to an arbitrary high impact and load bearing building panel (HILBBP) and a subsequence high impact and load bearing building panel (HILBBP). In order to efficiently attach the arbitrary HILBBP and the subsequence HILBBP together, the present invention utilizes the connecting seal section, a first connecting spline, and a second connecting spline. The first connecting spline and the second connecting spline each comprises a magnesium oxide board section and a phenolic resin sheet section as the magnesium oxide board section and the phenolic resin sheet section are adjacently laminated to each other. When the arbitrary HILBBP and the subsequence HILBBP are adjacently placed next to each other, the connecting seal section of the arbitrary HILBBP is traversed into the first spline-receiving groove of the subsequence HILBBP. The connecting seal section of the arbitrary HILBBP then overlaps the first edge of the phenolic resin sheet 12 for the subsequence HILBBP in such way that the connecting seal section and the first edge of the of the phenolic resin sheet 12 form a watertight seal. The connecting seal section of the arbitrary HILBBP forms a barrier against water and moisture intrusion into the building envelope system. Once the arbitrary HILBBP and the subsequence HILBBP are positioned together, the second spline-receiving groove and the fourth spline-receiving groove of the arbitrary HILBBP are respectively positioned with the first spline-receiving groove and the third spline-receiving groove of the subsequence HILBBP. The first connecting spline traverses into the first spline-receiving groove of the subsequence HILBBP and the second spline-receiving groove of the arbitrary HILBBP in such way that the phenolic resin sheet section of the first connecting spline is adjacently positioned with the expanded polystyrene layers 13, and the magnesium oxide board section of the first connecting spline is adjacently positioned with the connecting seal section. The second connecting spline traverses into the third spline-receiving groove of the subsequence HILBBP and the fourth spline-receiving groove of the arbitrary HILBBP in such way that the phenolic resin sheet section of the second connecting spline is adjacently positioned with the expanded polystyrene layers 13, and the magnesium oxide board section of the second connecting spline is adjacently positioned with the second magnesium oxide boards 14. A plurality of fasteners is used to attach the arbitrary HILBBP and the subsequence HILBBP during the multiple attachment of the present invention. More specifically, the plurality of fasteners is externally traversed through the first magnesium oxide boards 11 and the phenolic resin sheet 12 and into the first connecting spline so that the arbitrary HILBBP and the subsequence HILBBP can be attached to each other from the exterior side of the structural building. Similarly, the plurality of fasteners is externally traversed through the second magnesium oxide boards 14 and into the second connecting spline so that the arbitrary HILBBP and the subsequence HILBBP can be attached to each other from the interior side of the structural building.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
