Description

CROSS-REFERENCE TO RELATED APPLICATION

This is related to and claims priority from U.S. Provisional Patent Application Ser. No. 61/242,433, which was filed on Sep. 15, 2009.

FIELD OF THE INVENTION

The invention relates to building components, such as walls and other load-bearing structures, and for buildings and other structures constructed from these components. The invention also relates to processes for fabricating such building components, and for constructing buildings using such building components.

BACKGROUND OF THE INVENTION

There are many designs and fabrication methods and systems for walls and other load-bearing structures used in the construction industry. Such designs must balance the need for sturdy structures that will be long-lasting and can handle the stresses and loads of the given application, that are suitable for being finished in a manner that is suitable for the given application, and that are cost-effective. Cost-effectiveness of building components must take into account not only the cost of materials, but also the cost of fabrication and construction, of which ease and speed of fabrication are factors, as are weight and durability. There is always a need for a building component that is light-weight and strong, and that can be fabricated inexpensively and quickly on-site using commonly-fund materials, and which can easily be fabricated according to custom specifications.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1, a core element of the building component 1 is a central layer 2, preferably in the form of a panel. This panel is preferably made of a lightweight material, such as foam. For example, this foam panel can be made of expanded poly-styrene (E.P.S.), or a similar material that can function as the core of building component. Preferably, this panel is generally planar in shape, with optional inset channels 10 formed in either face or in both faces. It is contemplated that other panel shapes, such as curves or irregular shapes, can also be used. As shown in FIG. 4, these channels can take regular geometric shapes, such as the triangular 3, semi-circular 4, rectangular 5, and “tee” 6 shapes shown. It is contemplated that other geometric shapes or amorphous shapes can be used, and that the channels formed in a particular panel need not all have the same shape. The channels can be regularly spaced, as shown, or irregularly spaced according to the application. The panels can be pre-formed with the channels in place, or the channels can be cut from a planar sheet.
The channels formed in the central layer can be arranged in any suitable manner. For example, the channels can be formed such that they are mutually substantially parallel, forming regular columns. Alternatively, the channels can form a grid of perpendicular sets of mutually parallel channels, or curved central layers can include helixically-shaped channels. The channels can be cut or otherwise removed from a solid panel of the central layer, or the central layer can be molded with pre-set channels.
Thus, when the layer of hardened material is applied, the channels act as forms that are filled to create studs spaced along the face of the panel. The channels can be filled as part of the same process by which the self-hardening mixture is applied to the panel surface, or can be sprayed, troweled, poured, adhered, bonded, welded, strapped, held to, or applied/installed in any other way in a separate step. The end result is a structural building component having a lightweight central core, a hardened outer shell, and spaced rigid studs within the foam core.
As shown in FIG. 2, a hardening material 7, preferably in viscous form, is applied to at least one face, and preferably to both faces, of the central layer 2. The applied material is allowed to harden, and to cure if necessary, resulting in hardened surfaces on the faces of the panel. The surface can be finished, such as by sanding or applying a coating or texture, such as stucco, to the surface. The hardening material is preferably applied to each face such that it extends within any channels 10 formed in the face as described above.
Any type of hardening material can be used as the surface material. For example a concrete-based substance can be used, although non-concrete materials, such as Grancrete® can also be used as appropriate to the application. Shotcrete and gunite are also suitable materials, and it will be apparent to those of skill in the art that other materials can be advantageously used as well. The material can be troweled, sprayed, or otherwise applied to cover the faces of the central layer.
A cross-sectional view of an exemplary building component 1 according to the invention is shown in FIG. 3. This embodiment includes an optional reinforcing member 8 disposed within at least one channel, for example, in the form of a length of rebar. This optional element will add structural integrity to the building component, particularly if the component is to be used as a load-bearing component. Other materials such as metal, plastic, or wood can be added to the channel as reinforcement, or to the surface of the component for ornamentation.
As shown in FIG. 5, a number of the inventive building components 1 can be assembled together using any known means in order to construct any type of building structure 9. For example, the building component can be fabricated on-site as a wall unit, which can then be used to construct the interior or exterior space of a building as would any conventional wall unit.
The building component can also be laid flat as flooring, or used in any other application. More than one such building component can be stacked or arranged in any combination, geometric shape, or design to contract a complete structure or item that is not limited by the panel design. Once fabricated, individual building components 1 can be cut to size or shape to suit the particular application. Individual completed components can be connected by means known to those of skill in the art, and component ends and edges can have hardening material 2 or other finishing material applied so that the cross-sectional composition of the component is not exposed. Alternatively, numerous central layers can be arranged into a structural shape prior to forming the channel studs and applying the hardened outer surface.
Particular exemplary embodiments of the present invention have been described in detail. These exemplary embodiments are illustrative of the inventive concept recited in the appended claims, and are not limiting of the scope or spirit of the present invention as contemplated by the inventors.
