Description:

FIELD OF THE INVENTION

The present invention relates to a rigid foam building panel for use in a building system that utilizes panels made from rigid foam, which are reinforced by studs inserts.

BACKGROUND OF THE INVENTION

The following patents disclose the use of rigid foam with reinforcing stud inserts: U.S. Pat. No. 4,633,634 (Nemmer et al from 1987), U.S. Pat. No. 5,722,198 (Bader from 1998) and CA U.S. Pat. No. 2,363,216 (Ritchie from 2001). The systems disclosed use parallel-piped panels, which are only suitable for making box-like structures.

SUMMARY OF THE INVENTION

What is required is a rigid foam building panel, which will make rigid foam building systems more versatile.

According to the present invention there is provided a rigid foam building panel which includes a rigid foam body with elongate reinforcing studs. The rigid foam body has a first face, a second face, a top edge, a bottom edge and opposed side edges. Integrally formed non-planar architectural features are positioned on at least one of the first face or the second face.

The rigid foam building panel, as described above, can be made with selected non-planar architectural features, such as a concave curvature, a convex curvature, or an architectural moulding. Examples of architectural mouldings include: crown mouldings, chair rails, baseboard mouldings and columns.

According to another aspect of the present invention, the building panel is divided into modular sections, which are arranged one above the other. This enables a stock of crown moulding variations, chair moulding variations and baseboard moulding variations to be provided. The consumer selects the desired crown moulding variation, chair moulding variation and baseboard moulding variation. The building panel is then assembled from modular sections using the crown moulding variation, chair moulding variation and baseboard moulding variation selected by the consumer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The preferred embodiment, a rigid foam building panel-generally identified by reference numeral 10, will now be described with reference to FIGS. 1 through 5.

Structure and Relationship of Parts:

Referring now to FIG. 1, there is shown a structure 12 formed of rigid foam building panels 10. Rigid foam building panels 10 include a rigid foam body 14 with elongate reinforcing studs 16 and electrical conduits 17. Referring now to FIGS. 2 and 5, rigid foam body 14 has a first face 18, a second face 20, a top edge 22, a bottom edge 24 and opposed side edges 26. There are integrally formed non-planar architectural features 28 on either first face 18 or second face 20. Referring now to FIGS. 1 through 4, non-planar architectural feature 28 may be either a concave curvature 30, a convex curvature 32, or an architectural moulding such as a crown moulding 36, a chair rail 38, a column 40, or a base board moulding 42.

Referring now to FIG. 5, opposed side edges 26 of body 14 have grooves 44 extending between top edge 22 and bottom edge 24. Grooves 44 are adapted to receive a connecting spline 46, which allows bodies 14 to be connected together. Referring to FIGS. 2 and 3, body 14 is divided longitudinally into multiple modular sections 48 of upper and lower sections positioned one above the other. Modular sections 48 therefore allow for crown mouldings 36, baseboard mouldings 42, and chair rail mouldings 38 to be inserted. More than one upper and lower modular section 48 may be provided, each having a different crown moulding 26 or a different baseboard moulding.42, respectively. Referring now to FIG. 4, modular sections 48 are connected by using elongate vertical connectors 50 to connect them. Referring to FIG. 2, modular sections 48 fit together and are connected using a lap joint 52, where one section 48 has a depending tongue 54 which overlaps another modular section 48 positioned immediately below. Referring now to FIG. 3, lap joint 52 may also include a recess 58 that receives tongue 54. Referring to FIG. 5, sealing grooves 56 are positioned in opposed sides edges 26 immediately adjacent to first face 18 or second face 20, such that abutting bodies 14 are sealed by placing a sealant in sealing grooves 56.

Operation:

The use of rigid foam building panel 10 will now be discussed with reference to FIGS. 1 through 5. Referring now to FIG. 2 and 3, modular sections 48 are chosen according to the desired use and design of building panel 10, and may include architectural features 28 such as concave curvature 30, convex curvature 32, or an architectural moulding such as a crown moulding 36, a chair rail 38, or a base board moulding 42. The selected modular sections 48 are connected by lap joints 54, where tongue 54 either extends over the modular section 48 below, or fits into a recess 58. The sections are held together by vertical connectors 50. Once rigid foam building panels 10 have been assembled as desired, they are fit together to form the desired structure, such as that shown in FIG. 1. Referring to FIG. 5, rigid foam building panels 10 are held together by connecting spline 46 that is adapted to fit in grooves 44 formed in opposed side edges 26. Sealing grooves 56 are formed at the connection point of opposed side edges 26 and first or second face 18 or 20 such that abutting bodies 14 are sealed by placing a sealant in sealing grooves 56. Referring again to FIG. 1, bodies 14 need not be rectangular, and may include curved bodies 14 to allow for corners and other architectural features, such as columns 40.

It will be noted that a “C” channel is commonly used to support and install sectional walls. When working with curved and angled sections, however, this is no longer practical. What is preferred is an “L” shaped channel that may be installed on each side of the wall, if required. The vertical face attached to the wall, and the horizontal face may be cut to allow the vertical face to be bent around curves or corners.

In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.

It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
