Description
THEREOF AND METHOD FOR FORIVIING SUCH AN ARRANGMENT FIELD OF THE INVENTION The present invention relates to a sheet of wall cladding, an arrangement thereof, and a method of forming such an arrangement.
BACKGROUND OF THE INVENTION When assembling sheets of wall cladding, a user often spends a lot of time fastening the sheets to construction elements of a building. ln construction projects, installation time is a key aspect to consider. The amount of fasteners used is one of the factors driving the time it takes to install a sheet of wall cladding, as each fastener has to be installed separately. Also, damaging the sheets of wall cladding for example by collision with other structural elements at the build site may require them to be replaced, leading to an increase in both cost and time.
SUMMARY OF THE INVENTION lt is an object of the present invention to alleviate at least some of the mentioned drawbacks of the prior art and to provide a wall cladding that has good structural properties, and which saves time for the user by requiring fewer steps to install. This and other objects, which will become apparent in the following, are accomplished by a sheet of wall cladding and an arrangement thereof, as well as a method of forming such an arrangement, as is defined in the accompanying independent claims.
The term exemplary should in this application be understood as serving as an example, instance or illustration.
The present invention is at least partially based on the realisation that ordinary sheets of wall cladding require two rows of fasteners to be used when connecting the wall cladding to a structural element of a building. By overlapping the sheets of wall cladding, one row of fasteners may be removed. This is beneficial as it saves time for the user, and is enabled by the structural properties of the sheets of wall cladding defined in the following.
The present invention is furthermore based on the realisation that having structural properties that varies over the different portions of the sheets of wall cladding enables the use of previously unavailable structural arrangements.
According to the first aspect of the present invention, a sheet of wall cladding is provided. The sheet of wall cladding has two opposite faces, and two stepped edges located opposite each other. Each stepped edge has a stepped edge profile connecting the two faces of the wall cladding. The sheet of wall cladding is rotationally symmetric of order 2 along an axis of symmetry that is parallel with the two faces of the wall cladding and with the two stepped edges thereof.
The sheet of wall cladding being rotationally symmetric of order 2 along an axis of symmetry that is parallel with the two faces of the wall cladding and with the two stepped edges thereof means that rotating the sheet of wall cladding about an axis of symmetry going straight through the middle of the sheet, in a direction from an upper edge to a lower edge thereof, results in no geometric change of the sheet. This means that the sheet may be used with either face of the sheet facing inwards, and either face of the sheet facing outwards. Thus, an easier and more convenient installation process is achieved.
According to one example embodiment, the sheet of wall cladding further comprises an upper straight edge and a lower straight edge connecting the two faces thereof. The straight edges are located opposite each other and extend perpendicular to the stepped edges.
According to one example embodiment, the straight edges each define a flat surface extending between the two faces of the sheet of wall cladding. These edges may alternatively be referred to as upper and lower faces of the sheet.
According to one example embodiment, each one of the stepped edge profiles comprises a protrusion, arranged to mate with a corresponding, identical protrusion.
According to one example embodiment, said protrusions have a length that is 180 % to 220 % of the thickness of the sheet of wall cladding. This length is measured in a direction parallel with that of the extension of said protrusion.
According to one example embodiment, the sheet of wall cladding is made up from two integrally formed halves of equal thickness, the halves being defined by a plane that extends parallel with and between the two faces of the sheet of wall cladding.
According to one example embodiment, the protrusion of one half of the sheet of wall cladding is identical to the protrusion of the other half.
According to one example embodiment, each half of the sheet of wall cladding is mirror symmetric along a respective plane of symmetry extending perpendicular to the faces of the sheet of wall cladding, and parallel with the stepped edges thereof.
According to one example embodiment, an outer side of each protrusion is flush with a respective one of the two opposite faces of the sheet of wall cladding.
Alternatively, the outer side of at least one protrusion is provided with a recess for receiving a wall filler material.
According to one example embodiment, the sheet of wall cladding is made from gypsum or a fibreboard material. ln the context of the present invention, fibreboard is to be understood as being an engineered wood product that is made out of wood fibers. Fibreboard includes MDF, HDF, paperboard, and similar materials.
According to one example embodiment, the sheet of wall cladding has a midportion arranged between the two stepped edges thereof, wherein the strength of the sheet of wall cladding decreases from said midportion towards said stepped edges. ln one embodiment, the strength of the material in the sheet of wall cladding decreases gradually from said midportion towards said stepped edges. The decrease may be linear, or it may be exponential. Either way, the stepped edges are less brittle and more flexible than the midsection of the sheet of wall cladding. ln the context of the present invention, strength may be understood as being the brittleness or hardness of the material. As such, the midsection is harder, but more brittle, than the stepped edges. Thus, more flexible, less brittle protrusions are achieved. This decreases the risk of the protrusions breaking when arranging the sheets of wall cladding in a wall cladding arrangement.
Generally, the strength of a material is its ability to withstand an applied load without failure or plastic deformation. Strength of materials considers the relationship between the external loads applied to a material and the resulting deformation or change in material dimensions.
According to one example embodiment, the sheet of wall cladding further comprises a reinforcement material provided at the stepped edges thereof.
According to one example embodiment, said reinforcement material is integrally formed in a portion of the sheet of wall cladding.
According to a second aspect of the present invention, a wall cladding arrangement is provided. The wall cladding arrangement comprises sheets of wall cladding according to any one of the preceding claims, wherein said sheets of wall cladding are arranged such that the stepped edge of one of the sheets of wall cladding overlap the opposite stepped edge of an adjacent sheet of wall cladding, and wherein the stepped edges are joined by a plurality of fasteners provided thereat.
According to one example embodiment, the connection means could for example be a screw or a nail.
According to a third aspect of the present invention, a method for mounting sheets of wall cladding according to the first aspect of the present invention in an arrangement according to the second aspect of the present invention to a construction element of a building is provided. The method comprises: providing a first sheet of wall cladding; arranging the stepped edge of the first sheet of wall cladding along a construction element; providing a second sheet of wall cladding; overlapping the stepped edge of the first sheet of wall cladding with the stepped edge of the second sheet of wall cladding such that both stepped edges are arranged along the construction element; joining the two stepped edges by means of a plurality of fasteners, wherein each one of said plurality of fasteners also engages the construction element of said building.
Generally, all terms used in the description are to be interpreted according to their ordinary meaning in the technical field, unless explicitly defined otherwise herein. All references to "a/an/the [element, device, component, means, step, etc.]" are to be interpreted openly as referring to at least one instance of said element, device, component, means, step, etc., unless explicitly stated otherwise.

Figure 3 is a section view of the sheet of wall cladding 1 of Figure 1 with one of the two halves 14, 15 thereof highlighted.
The sheet of wall cladding 1 illustrated has two opposite faces 2, 3, corresponding to an inner side and an outer side of the sheet of wall cladding 1. At either side thereof, the sheet of wall cladding 1 has two stepped edges 4, 5 that are located opposite each other. The top and bottom of the sheet of wall cladding 1 is provided with an upper straight edge 8 and a lower straight edge 9, respectively, that connects the two faces 2, 3 thereof. The straight edges 8, 9 are located opposite each other and extend perpendicular to the stepped edges 4, 5. The straight edges 8, 9 are arranged such that they each define a flat surface 10, 11 extending between the two faces 2, 3 of the sheet of wall cladding 1.
The two stepped edges 4, 5 each have a stepped edge profile 6, 7 connecting the two faces 3, 4 of the wall cladding 1. The stepped edge profiles 6, 7 each comprise a protrusion 12, 13 arranged to mate with a corresponding, identical protrusion 12, 13 of another sheet of wall cladding 1. The protrusions 12, 13 have a length that is approximately twice that of the thickness of the sheet of wall cladding 1, and an outer side 16, 17 of each protrusion 12, 13 is flush with a respective one of the two opposite faces 2, 3 of the sheet of wall cladding 1. As such, only one stepped edge profile 6, 7 is seen when viewing the sheet of wall cladding 1 straight from either the front or the back.
The sheet of wall cladding 1 itself is made up from two integrally formed halves 14, 15 of equal thickness, the halves 14, 15 being defined by a plane P1 that extends parallel with and between the two faces 2, 3 of the sheet of wall cladding 1. The protrusion 12 of one half 14 of the sheet of wall cladding 1 is identical to the protrusion 13 of the other half 15, as each half 14, 15 of the sheet of wall cladding 1 is mirror symmetric along a respective plane of symmetry P2 extending perpendicular to the faces 2, 3 of the sheet of wall cladding 1, and parallel with the stepped edges 4, 5 thereof.
