Abstract

In its preferred form the present invention provides a building corner construction particularly suitable for providing substantially pre-finished corners for interior wall cladding. Adjoining panels (10, 11, 30, 31) are connected by a common, continuous sheet of surface material (12, 34) such as paper or card, with a gap between the facing edges of the panels at least equal in width to the thickness of the edge of one panel. A strip of thin, stiff material (15) such as metal may be rebated into one panel edge to extend across the gap, and support the surface material. Alternatively, a corner may be formed by making a longitudinal groove (35) in a rigid sheet of material (36), such as plaster board, but not through the sheet of material (34), and then folding the panel along the groove.

Description

BUILDING CORNER CONSTRUCTION
BACKGROUND OF THE INVENTION
The present invention relates to the general field of building comer construction, with particular application to building co ers made of panel material.
A wide variety of different systems have been used to dress interior wall and ceiling surfaces, so as to present a clean, finished appearance in themselves, or to be ready for the application of paper or other finishing materials. The most difficult part of such work is usually in finishing the comers, where the wall panels themselves are most rough, and where access is sometimes most restricted.
It is an object of the present invention to go at least part way towards providing a novel or improved building comer construction, or at least to provide the public with a useful choice.
SUMMARY OF THE INVENTION
According to one aspect of the present invention, there is provided a building comer construction including a pair of panels connected along parallel edges thereof by a flexible sheet, said sheet comprising a common surface layer extending across at least part of said panels.
Preferably the building comer construction comprises a single panel of substantially rigid building material, said single panel having a face covered with said flexible sheet and having another face on the opposite side to said covered face, said single sheet having a substantially straight groove formed in said another face and at least part way through the rigid material but not through the flexible sheet, whereby the a single panel is divided by the groove into said pair of panels, said pair of panels being folded about the flexible sheet along the line of the groove to form a comer.
Preferably the groove is cut fully through the rigid building material, leaving the flexible sheet to function as a hinge. The sides of the groove may be flat and, before the comer is folded, have an included angle therebetween equal to the supplement of the angle between the pair of panels after forming into the comer.
Conveniently, the sides of the groove, before folding, are symmetrically formed either side of a plane normal to the face covered by the flexible sheet and through the longitudinal centre of the groove.
According to another aspect of the invention there is provided a building corner construction formed into a pillar by the steps of taking said single panel, forming a groove for each comer in the final pillar, folding the panel along each groove, bringing the side edges of the panel close together and fastening them.
The pillar preferably includes at least one transverse body affixed to the interior of the pillar to retain the cross-section of the pillar.
According to a further aspect of the invention said parallel edges are spaced apart by a distance at least equal to the thickness of one said panel.
Advantageously, a thin, relatively stiff strip of material is fixed to said sheet between said parallel edges of the panels, and fixed to one said panel.
Preferably, the or each panel is formed of a rigid mineral or vegetable particle or fibre material. An alternative material for the panel would be a rigid or semi-rigid plastic panel with a flexible covering.

DETAILED DESCRIPTION
The present invention provides a panel system by which some of the difficulties encountered with finishing comers may be overcome. As illustrated in Figure 1, one preferred embodiment of the present invention comprises a pair of panels 10 and 11, formed of plaster board, vegetable particle or fibre board or the like, joined by a common surface sheet 12. The sheet 12 may be card or paper, preferably of a type commonly used in panel surfacing, and of a type matched to other, adjoining panels.
Facing edges 10a and 11a of the two panels are spaced apart to leave a gap 13, preferably at least equal in width to the thickness of a panel. Additionally or alternatively either or both panel edges 10a and 11a may be bevelled as shown. Both the gap 13 and the bevelling of the panel edges provide a clearance between the panel edges, which allows the two panels to be angled at an acute angle of 90 degrees or less to one another, as shown in Figure 2. The same construction can be used to accommodate angles from about 20 degrees to about 340 degrees.
To strengthen the surface sheet 12 across the gap 13, a thin metal strip 15 is preferably rebated into one panel edge 10a, and extends across the back of the sheet 12 almost into contact with the edge 1 la of the other panel 11, stopping short to leave a gap 16 about equal to the thickness of the metal. The strip 15 is preferably glued to the surface sheet 12, and also to the panel 10 into which it is rebated. In use, the panels 10 and 11 can simply be fastened to adjoining wall frames, with the surface sheet 12 bending at the gap 16 between the edge of the metal strip 15 and the edge 1 la of the panel, to form the comer. The sheet material 12 may be pressed or scored at the gap 16 to control the bend, if desired. The same panels can be used without modification for either external comers as shown in Figures 1 and 2, or internal corners as shown in Figure 3 and this is a significant advantage allowing for ease of use without the need to stock a range of fixed internal or external comers. Comers of other than 90 degrees can easily be formed simply by fixing the panels to a support structure at the desired angle, and the same join can connect panels in the same plane, to provide a substantially seamless wall surface.
As shown in Figure 4, an alternative embodiment of the invention comprises an end- piece for use in finishing door or window frames or the like. A pair of panels 20 and 21 are connected on either side of a framing member 24 by a continuous surface sheet 22 extending across all three. Edges 20a and 21a of the panels are spaced away from the sides of the framing member 24 to leave gaps 23, with strips 25 extending across each gap to support the surface sheet 22. As shown, it is preferable for the strips 25 to be rebated into and fixed to the panels, rather than the framing member 24, so that in practice the full width of the end-piece is backed by the solid material of the framing member 24, into which hinges or latches for doors or windows can be fitted. Similarly, it may be preferable for the edges of the framing member 24 to be left square, rather than being bevelled as shown, to avoid weakening the sides of the framing member. It will be appreciated that such an arrangement would prevent the framing member from being positioned at less than 90 degrees to either or both panels 20 and 21. A 90 degree angle is most commonly required at the ends of walls in practice.
The framing member is illustrated as being a standard timber jamb, but is should be appreciated that a metal framing member might equally be used, or a panel of equal thickness to the panels 20 and 21 but of a more solid material. If the panels 20 and 21 were of plaster board or the like, the framing member 24 might for example be comprised of particle board of die same thickness. This would allow the three panels to be fixed in the same plane to form a smooth wall surface; or allow the framing member and one panel 20 to be fixed in one plane and the other panel 21 set at 90 degrees to form a right angle comer, or allow both panels to be set at 90 degrees to the framing member to form a wall end-piece, according to need.
When the panels are fixed in place on a support stracture it may be found desirable to set and strengthen the comer, by applying a settable material such as a putty or glue in the gap 16. It will be appreciated that the apex of the co er lies at the gap 16, and accordingly is comprised only of the surface sheet 12. Particularly in the case of external comers, the apex is often knocked or worn by traffic passing around it, and may be damaged unless supported from behind. Alternatively, the metal strip 15 might have a rounded beading along its edge, to provide a smooth surface behind the sheet 12 at the gap 16.
A variety of other changes and modifications might also be made to the examples illustrated above within the general scope of the invention. While the examples above relate to interior wall cladding, it should be appreciated that the invention might also be used with exterior surfaces, with appropriate materials. The surface sheet 12 could comprise a fabric or netting, or metal, or a variety of other materials to suit particular applications. Similarly, the panels need not comprise solid sheets, but rather might comprise a framework of struts, or perforated sheets, depending on the purposes for which the structure is intended.
In the case of other composite panel boards such as plaster board, it is preferable to provide metal reinforcement on both boards. The construction of the joint might also be varied. For example, the strip 15 can be formed as an integral part of a panel or panel frame, and can be formed from plastics or other materials. A plastic or metal moulding could include a weakened hinge portion and extend across the entire width of the gap 13, to connect to both panels. Other hinge structures could also be used in this way.
The sheet material 12 can be modified by creating a plurality of closely spaced hinge lines to allow the material to approximate to a radiused comer.
A variety of other changes and modifications might also be made within the general spirit and scope of the present invention. Figure 5 shows a corner construction for use as the end of a wall, for example in a doorway or a window. The construction is U-shaped, having a pair of parallel limbs 30 and a base 31 having abutting mitred faces 32 at the comers.
Figure 6 shows the panel from which the construction of Figure 5 is made. A sheet of plaster board 33 is covered on at least one face by a sheet of strong paper, card, cloth or the like 34. A pair of parallel grooves 35 are cut through the plaster 36 as far as the sheet 34 but not through it. The grooves 35 may stop slightly short of the sheet 34 in some embodiments. The faces 32 are at 90 degrees to each other ie. at 45 degrees from a plane normal to the sheet 34. If the angle between one of the limbs 30 and the base 31 is to be other than 90 degrees, the angle between the faces 32 must be adjusted accordingly. If preferred, the faces 32 need not be symmetrical to the sheet 34, provided that the angle between the faces 32 produces the required angle between the limb 30 and base 31.
Figures 7 and 8 show how a pillar 37 is formed from a panel of suitable material, such as plaster board, or a plastic panel with a flexible covering, or a wood particle, wood fibre or the like panel with a flexible covering. The most preferred material for such a pillar is Medium Density Fibreboard (MDF) which has been cut and bevelled into separate strips 36 and glued onto a flexible backing layer 34 (similar to that shown in Figure 6). Alternatively the flexible material can be glued to die MDF sheet before cutting or milling the grooves 35. The most preferred method of manufacture is to route the grooves at an angle of 45° or more. An angle in excess of 45" allows for a layer of glue when the pillar is glued up, and also allows for sharper comers than 90* if required. Starting with a panel of appropriate width, four grooves 35, of the kind shown in Figure 6, are formed into the panel, which is folded up to form the section shown in Figure 7 and optionally each comer may be glued. The side edges 38 are brought together and an appropriate number of transverse blocks or panels 39 are fastened inside the pillar 37, for example by adhesive and/or nails, screws or the like. The blocks 39 maintain the correct cross section of the pillar. Such a pillar can be used as a lightweight hollow stud for walls, especially walls for offices or homes where the wall may be covered with plaster board or the like.
For some embodiments, the faces 32 on each side of one of the grooves 35 need not be flat, provided they fit against each other when the panel is folded.
