Description

[0001] The invention relates to a cladding element for fastening to a facade of a building according to patent claim 1.

[0002] It is well known that building facades can be clad with wood, marble, or aluminum panels. This can achieve better thermal insulation and an aesthetically pleasing exterior.

[0003] As a rule, the panels are inserted or hung into rails pre-installed on the exterior wall of the building.

[0004] The disadvantage is that a special scaffold supporting the panels must be attached to the building's exterior wall, which is cumbersome, time-consuming, and expensive. The manufacture and installation of such panels also requires high precision to prevent water from penetrating through the gaps between the panels, which could encourage mold growth.

[0005] The object of the invention is therefore to provide a cladding element of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, which can be positioned and installed easily and quickly, whereby an aesthetically pleasing flat and rainproof surface is achieved.

[0006] According to the invention, this is achieved by the features of patent claim 1.

[0007] This offers the advantage that the cladding element can be positioned and installed quickly and easily. Using several such cladding elements, an aesthetically pleasing, flat, and rainproof facade can be created. The at least one fastening opening allows the cladding element to be easily attached to a building's exterior wall, in particular to wooden beams arranged on the building's exterior wall. The second positioning element allows the cladding element to be easily engaged with at least one first positioning element of another cladding element, thus reliably positioning it. Precise positioning can also assist in creating a rainproof building facade.

[0008] The invention further relates to a building facade according to claim 9.

[0009] The invention will be described in more detail with reference to the accompanying drawings, in which only preferred embodiments are shown by way of example. In the drawings: Fig. 1 an exemplary representation of a preferred embodiment of a cladding element in plan view; Fig. 2 an exemplary representation of the preferred embodiment of the cladding element in bottom view; Fig. 3 an exemplary representation of the preferred embodiment of the cladding element in a first side view; Fig. 4 an exemplary representation of the preferred embodiment of the cladding element in a second side view; Fig. 5 an exemplary representation of the preferred embodiment of the cladding element in a rear view; Fig. 6 an exemplary representation of the preferred embodiment of the cladding element in a front view; Fig. 7an exemplary representation of a preferred embodiment of a building facade comprising several cladding elements in a front view; Fig. 8 an exemplary representation of the preferred embodiment of the building facade comprising several cladding elements in a side view; Fig. 9 an exemplary representation of the preferred embodiment of the building facade comprising several cladding elements as a section in a side view; Fig. 10 an exemplary representation of a further preferred embodiment of a building facade comprising several cladding elements in a further laying pattern in a front view.

[0010] The Fig. 1 to 10show at least parts of a cladding element 1 for fastening to a facade of a building, wherein the cladding element 1 has a substantially planar outer visible surface 2 with a first edge 3 and a second edge 4 opposite the first edge 3, wherein a step 5 comprising a first flank 6 with a flank height and a step surface 7 is arranged on the first edge 3, wherein on the step surface 7, which is spaced from the first edge 3 by the flank height by the first flank 6, at least one fastening opening 8 for fastening the cladding element 1 to a facade and at least one first positioning element 9 is arranged, wherein a second flank 10 with the flank height is arranged on the second edge 4,and wherein at least one second positioning element 12 for engagement with at least one first positioning element 9 of a further cladding element 1 is arranged on an underside 11 of the cladding element 1 opposite the visible surface 2 in an edge region adjacent to the second flank 10.

[0011] This results in the advantage that the cladding element 1 can be positioned and installed quickly and easily. By using several such cladding elements 1, an aesthetically pleasing, flat, and rainproof facade can be achieved. The at least one fastening opening 8 allows the cladding element 1 to be easily attached to an external building wall, in particular to wooden beams arranged on the external building wall. The second positioning element 12 allows the cladding element 1 to be easily brought into engagement with at least one first positioning element 9 of another cladding element 1 and thus reliably positioned. The precise positioning can also assist in the creation of a rainproof building facade 17.

[0012] The cladding element 1 is attached to a facade of a building, thus to the exterior wall of a building. Wooden beams can preferably be arranged on the exterior wall of a building, to which the cladding element 1 is attached, in particular nailed.

[0013] The cladding element 1 has a substantially flat outer visible surface 2. A substantially flat outer visible surface 2 means that the visible surface 2 is essentially flat, continuous, and free of bulges at the macroscopic level. The visible surface 2 may be patterned for aesthetic reasons.

[0014] A first edge 3 and a second edge 4, opposite the first edge 3, are arranged on the visible surface 2. A step 5 comprising a first flank 6 with a flank height and a step surface 7 is arranged on the first edge 3. The step surface 7 is spaced from the first edge 3 by the flank height by the first flank 6. At least one fastening opening 8 for fastening the cladding element 1 to a facade and at least one first positioning element 9 are arranged on the step surface 7.

[0015] A second flank 10 with the flank height is arranged on the second edge 4. On an underside 11 of the cladding element 1 opposite the visible surface 2, in an edge region adjacent to the second flank 10, at least one second positioning element 12 is arranged for engagement with at least one first positioning element 9 of another cladding element 1.

[0016] The visible surface 2 can also be referred to as the top side of the cladding element 1. The flank height refers to the height between the first edge 3 and the step surface 7. The flank height of the first flank 6 is essentially identical to the flank height of the second flank 10, which can be seen by way of example in the figures. This allows the production of a flat facade or a flat cladding of the exterior wall of a building, which can be seen by way of example in the Fig. 7 to Fig. 10 is shown.

[0017] Particularly preferably, it can be provided that the cladding element 1 is wedge-shaped in a longitudinal section or in a side view, which is shown in the Figures 3, 4 and 8 The wedge shape allows, as shown in Figure 8As shown by way of example, a substantially flat building facade 17 can be produced simply and reliably. This is made possible by the fact that the step surface 7 is spaced from the first edge 3 by the flank height and that a second flank 10 with the same flank height is arranged on the second edge 4.

[0018] Furthermore, a building façade 17 comprising an arrangement of several cladding elements 1 is provided, wherein two adjacent cladding elements 1 are arranged by means of first and second positioning elements 9, 12. Sections of a building façade 17 with preferred laying patterns are shown in the Figures 7 to 9 shown as an example.

[0019] In the case of the building facade 17, it can be particularly preferably provided that the visible surfaces 2 of the cladding elements 1 are arranged in a common plane. By arranging the visible surfaces 2 in a common plane, an attractive appearance similar to tiles is achieved, without the need for joints. Furthermore, this smooth surface ensures that no edges of the cladding elements 1 protrude from the building facade 17, as would be the case with a roof tile-like arrangement, thereby reducing the risk of edges of the cladding elements 1 being damaged and, subsequently, people being injured by the broken edges.

[0020] It can preferably be provided that the at least one first positioning element 9 is designed to be opposite to the at least one second positioning element 12. This enables precise positioning of the cladding elements 1.

[0021] It can furthermore preferably be provided that the first positioning element 9 is designed as at least one elevation and that the second positioning element 12 is designed as at least one recess. This allows a further cladding element 1 to be positioned easily and reliably on the cladding element 1.

[0022] Alternatively, it can also be provided that the first positioning element 9 is designed as at least one recess and that the second positioning element 12 is designed as at least one elevation.

[0023] It can also be provided that the first positioning element 9 is designed as a plurality of elevations and that the second positioning element 12 is designed as a plurality of recesses.

[0024] It can also be provided that the first positioning element 9 comprises at least one elevation and at least one recess and that the second positioning element 12 comprises at least one elevation and at least one recess.

[0025] It can also be provided that the first positioning element 9 comprises at least one elevation and at least one recess and that the second positioning element 12 comprises at least one recess formed in the opposite direction to the at least one elevation of the first positioning element 9 and at least one elevation formed in the opposite direction to the recess of the first positioning element 9.

[0026] The at least one elevation and at least one recess can in particular extend substantially normal to the plane of the visible surface 2.

[0027] It can preferably be provided that the at least one elevation is substantially trapezoidal in cross-section and that the side surfaces of the at least one recess are designed as sliding surfaces. This further facilitates the positioning of the cladding elements 1.

[0028] Preferably, the at least one recess can be larger than the at least one elevation by a predetermined amount. This can prevent any stresses caused by temperature changes.

[0029] In particular, several stiffening elements 21, in particular stiffening ribs, can be arranged on the underside 11.

[0030] Preferably, the cladding element 1 can have two first positioning elements 9, the centers of which are spaced apart from each other by half the width of the visible surface 2. This allows two cladding elements 1 to be arranged offset from each other by half the width.

[0031] It can further preferably be provided that a third positioning element 14 is arranged on a third edge 13 of the visible surface 2, which connects the first edge 3 to the second edge 4, and a fourth positioning element 16 for engagement with the third positioning element 14 of a further cladding element 1 is arranged on a fourth edge 15, opposite the third edge 13 and connecting the first edge 3 to the second edge 4. As a result, the cladding element 1 can be positioned not only vertically but also horizontally in an assembled state. Furthermore, this prevents or at least reduces any displacement of cladding elements 1 relative to one another.

[0032] Preferably, the cladding element 1 can be designed such that the third edge 14 of one cladding element 1 overlaps with the fourth edge 16 of an adjacent cladding element 1. In this case, the third edge 14 can be arranged set back by means of a further step, as viewed from the visible surface 2.

[0033] Preferably, it can be provided that the third positioning element 14 is designed as a groove. For this purpose, the third positioning element 14 preferably has at least one web and adjacent thereto at least one groove, which is exemplified in Fig. 1This enables simple manufacture of the third positioning element 14, wherein, in an assembled state, the web of a third positioning element 14 engages in a recess of a fourth positioning element 16. The third positioning element 14, designed as a channel, also allows water penetrating between the third edge 13 and the fourth edge 15 to be drained away.

[0034] In particular, the channel can be at least as long as the parallel longitudinal extension of the visible surface 2.

[0035] In particular, it can be provided that the channel runs obliquely to the visible surface 2, wherein the distance between the channel and the visible surface decreases from the first edge 3 to the second edge 4. As in Fig. 8 As can be seen, water can be directed from the gutter of a cladding element 1 into the gutter of the cladding element 1 arranged below.

[0036] The fourth positioning element 16 can be designed as an elevation which engages in the third positioning element 14 designed as a groove, but does not close the groove.

[0037] Furthermore, it can be provided that two adjacently arranged cladding elements 1 are engaged with each other by means of third and fourth positioning elements 14, 16.

[0038] The precise positioning of the cladding elements 1 relative to one another by means of the positioning elements 9, 12, 14, 16 not only creates an attractive appearance, but also ensures that no gaps can form between the cladding elements 1 during installation, which also prevents water from penetrating the supporting substructure.

[0039] Particularly preferably, it can be provided that the cladding element 1 is formed in one piece.

[0040] In particular, it can be provided that the cladding element 1 is designed to be substantially free of undercuts when viewed perpendicular to the visible surface 2. The cladding element 1 can be designed to be free of undercuts, in particular on the side of the visible surface 1 and / or on the side of the underside 11. As a result, the cladding element 1 can be formed in two flat shapes without a subsequent material-removing process.

[0041] Particularly preferably, the cladding element 1 can be designed as a molded piece. The cladding elements 1 can therefore preferably be compression-molded. In contrast to extruded elements, pressing in a mold allows the four peripheral edges 3, 4, 13, 15 to be shaped in such a way that they permit a rainproof connection.

[0042] Preferably, the cladding element 1 can be made of ceramic. This enables simple and environmentally friendly production, unlike, for example, aluminum panels. Furthermore, ceramic is particularly resistant to environmental influences.

[0043] Alternatively, the cladding element 1 can also be made of artificial stone, in particular concrete, or plastic.

[0044] The assembly state of the cladding elements 1 as building facade 17 is shown as an example in the Figures 7 to 10 shown.

[0045] In the Fig. 7 A first installation pattern is shown as an example. Here, cladding elements 1 are laid symmetrically with essentially the same joint spacing, thus achieving uniform rows with uniform joint spacing between the individual cladding elements 1.

[0046] In the Fig. 10A second installation pattern is shown as an example. Here, cladding elements 1 of a first row 18 are offset by half the width of the visible surface 2 relative to a second row 19. This results in a symmetrical arrangement of the first row 18 relative to a third row 20 and the second row 19 relative to a Fig. 9 fourth row, not shown.

[0047] Fig. 1shows an exemplary representation of a preferred embodiment of the cladding element 1 comprising a substantially square visible surface 2 on the upper side of the cladding element 1, a first edge 3 and adjacent to and spaced therefrom a second edge 4, wherein the first edge 3 and the second edge 4 delimit the visible surface 2 on two opposite sides, a step 5 arranged on the first edge 3 with a step surface 7, fastening openings 8 arranged on the step surface 7 for receiving fastening means, in particular nails, wherein the visible surface 2 is spaced from the step surface 7 by the flank height, two first positioning elements 9 in the form of elevations are arranged at a distance from one another and arranged on the step surface 7.

[0048] Fig. 2shows an exemplary representation of the underside 11 of the preferred embodiment of the cladding element 1 with the two fastening openings 8, two second positioning elements 12 in the form of recesses, a fourth positioning element 16 comprising a web and a recess and several stiffening elements 21.

[0049] The Figures 3 to 6 show side views, a front view and a rear view of the preferred embodiment of the cladding element 1.

[0050] Fig. 7 shows a first laying pattern and Fig. 10 a second laying pattern as previously described.

[0051] Fig. 8 shows a side view of a building facade 17 comprising several cladding elements 1. Here, first positioning elements 9 are engaged with second positioning elements 12, not shown in this figure. Furthermore, the cladding elements 1 are nailed to wooden beams.

[0052] Fig. 9shows the building facade 17 in section through the first positioning element 9 and the second positioning element 12, which are engaged.

[0053] Preferably, the visible surface 2 is rectangular, particularly preferably substantially square.

[0054] Preferably, the cladding element 1 can have a length of at least 10 cm, in particular at least 30 cm, preferably at least 50 cm.

[0055] Preferably, the cladding element 1 can have a width of at least 7 cm. The following are principles for the understanding and interpretation of the present disclosure.

[0056] Characteristics are usually introduced with an indefinite article, "ein, eine, eines, einer." Therefore, unless the context indicates otherwise, "ein, eine, eines, einer" is not to be understood as a number.
