Description

The invention relates to a cladding element, which is an insulation board for a wall of a building, with an inner wall-side boundary surface and an outer, wall facing away boundary surface.

Furthermore, the invention relates to a wall cladding consisting of a number of such cladding elements.

Currently, it is common to provide houses with thermal insulation. For this purpose, the building wall is clad on its outside with cladding elements, for example, with insulation boards made of polystyrene. This insulation reduces the building heat loss through the outer wall.

On its outside, the cladding elements are plastered (i.e., a putty is applied to the cladding elements, then a reinforcement, a further putty, primer and finally the plaster layer) and thus also form a weather protection for the building.

Another requirement placed on such cladding panels is that they must be capable of adequately diffusing water vapor from inside the building to ensure that little or no condensation can form. Excessive condensation can cause damage to the wall and mold indoors.

document DE 29 31 223 A1 discloses an insulation board for a wall of a building, having a first boundary surface and a second boundary surface, wherein between the first boundary surface and the second boundary surface exactly one cavity is arranged, which cavity from a mounting position lower boundary surface of the insulation board to an upper boundary surface of the Insulating plate extends, and further wherein at least one perforation is provided, which extends starting from the first boundary surface into the cavity, and wherein the formation of the cavity, the insulation board has a two-part construction, wherein a first part and a second part (10) of Insulating plate by means of spacers are spaced from each other and wherein the spacers in the form of discrete, protruding from the first part or preferably the second part, for example, cylindrical or in the form of a cylinder stub, such as a circular cylinder stub formed pimples are formed.

It is an object of the invention to provide a cladding element, which in addition to the necessary strength also provides good ventilation of the facade of the building. Preferably, the insulating properties of the cladding element should receive stay.

This object is achieved by a erfidungsgemässe insulation board having the features of claim 1.

With a cladding element according to the invention, which is an insulation board, a ventilated facade can be realized, in which rises in the cavities of superimposed trim elements water vapor that passes through the holes in the cladding elements of the building in the cavities, upwards in the cavities and emerges from the top cladding elements at the top of the building and is thus easily and safely removed from the building.

In addition, a decoupling of the wall-side region from the outer region, so that high or low temperatures or temperature fluctuations are not or only delayed delivered to the wall-side region of the cladding element. In order to allow an optimal discharge of water vapor, and at the same time to ensure sufficient mechanical stability of the cladding element is provided in a variant of the invention that two or preferably a plurality of cavities extending from the lower to the upper boundary surface, between the inner and the outer boundary surface are provided.

For a uniform removal of water vapor from the building, it is advantageous if the cavities are distributed uniformly over the width of the cladding element. In terms of manufacturing technology, it is simpler if the at least one cavity in a state of the cladding element fixed to a building wall is substantially straight and preferably substantially vertically running.

A straight-line configuration makes it possible to design the cavities in the form of channels and form as short and without curvature, so that the water vapor can be dissipated quickly. The channels are preferably vertical trained, but it may also be possible depending on the design that they take a certain inclination to the vertical.

It is particularly advantageous if two or more, preferably a plurality of perforations is provided.

Furthermore, it is advantageous if the perforations are distributed uniformly over the width and / or height of the cladding element.

In this way, the water vapor over the entire surface of the cladding element can be dissipated uniformly.

It is preferably provided that the perforations are normal to the inner wall boundary surface.

This results in short holes, so that water vapor can get into the cavities or quickly, also this manufacturing technology is easy to manufacture.

When connecting the inner part to the outer part, the spacers form one or more cavities between the two parts in the interior of the cladding element.

Manufacturing technology, such a cladding element can be made easier than when manufactured from only one part, are to be arranged in the interior cavities.

The above-mentioned decoupling of the interior and exterior of the cladding element is particularly well in such a two-part construction of the cladding element to fruition. In addition, the inner part is statically not or less stressed and other influences, such as weather conditions not exposed, so that the insulating properties of the inner part are not reduced by such stress.

In this embodiment, it is provided that the perforations are arranged on the inner part and pass through the inner part of the building-side inner boundary surface to its outer surface facing the outer part.

As mentioned above, the spacers are arranged such that the one or more cavities are formed as extending from bottom to top, preferably straight, in particular substantially vertical channels between the inner part and the outer part.

In a particularly preferred embodiment it is provided that the spacers - in the assembled state of the cladding element - not connected to the inner part or preferably with the outer part, preferably are made in one piece with the inner part or outer part.

In principle, spacers, inner part and outer part can be designed as separate components. In order to limit the number of components and to simplify the assembly, it is, however, advantageous if the spacers are connected to the inner part or the outer part, preferably in one piece with this.

In principle, spacers could also be arranged on both parts, but it is simpler in manufacture and in assembly if the spacers (in the assembled state of the cladding element) are arranged only on one component.

Preferably, these are mounted on the outer part and formed integrally therewith, since the outer part, as further explained below, preferably has a higher strength than the inner part, and thus also the spacers have a higher strength.

In a variant of the invention, the spacers are formed as continuous, extending from the upper boundary surface to the lower boundary surface webs.

In this way, continuous, from top to bottom extending channels are formed, which are separated from each other.

In the insulating panel of the invention, the spacers in the form of projecting from the inner part or preferably the outer part, for example cylindrical or in the form of a cylinder stub, such as a circular cylinder stub formed nubs are formed.

These nubs may basically have any cross-sectional shape, e.g. a circular cross-section, angular, e.g. have rectangular cross section, wherein in a specific embodiment, a circular cylinder stump is provided with a circular base.

Furthermore, it is advantageously provided that the spacers in the form of extensions are distributed substantially uniformly over an outer surface of the inner part or over an inner surface of the outer part.

When using such "discrete" spacers in the form of nubs, the cladding element does not have any self-contained channels in its interior, but the (substantially) vertical channels are interconnected by transverse channels. The smaller the cross-sectional areas of the individual spacers compared to the surface of the outer surface of the inner part or to the inner surface of the outer part (whose surfaces are identical to the boundary surfaces of the cladding element), the more dissolves the structure of several individual channels and then it lies in the Essentially, a single cavity between the two components, which extends from bottom to top. This cavity is penetrated by the spacers.

Furthermore, it is advantageously provided that a structure in the form of one or more depressions is provided on the boundary surface remote from the wall and / or the boundary surface facing the wall.

These recesses are provided, for example in the form of elongated incisions which intersect in a honeycomb arrangement, on the outside and / or the inside of the cladding element and lead to a better adhesion of the Filling and thus the external plaster (on the outside) and a better grip of the adhesive (adhesive mortar) on the inside, with which the cladding element is attached to a building.

Furthermore, it can be provided that mounting holes are provided on the outer part, which extend from the wall facing away from the boundary surface by the spacers, in particular by the extensions therethrough.

About this Befestigungslochungen the inner part and the outer part can be connected to each other, for example, by applying adhesive from the outside through the mounting holes, with which the knobs of the outer part are then glued to the inner part.

The mounting holes may alternatively or preferably additionally be provided so that they allow a simpler positioning of the cladding element on the wall of a building. In certain cases, such as the renovation of old buildings, it is often prescribed that the cladding elements are dowelled in addition to the gluing even to the wall. The mounting holes now show the user where he can peg the cladding element with the wall, and it ensures that the dowel passes through the cladding element in the region of the knobs and not in the cavity of the cladding element.

The mounting holes can be formed already the production of the cladding element, or these are subsequently attached in the form of holes.

An alternative possibility for connecting the outer part and the inner part of the cladding element is that the adhesive is applied directly in the contact area between the knobs and the inner part. In this case, the mounting holes for introducing the adhesive are not necessary, but for a fixing of the cladding element to the wall of a building as described above, these are still advantageous.

It is particularly advantageous if the inner part and the outer part have different strength, wherein preferably the outer part has a higher strength than the inner part.

A higher strength of the outer part, so a higher density of the material used in the outer part has the advantage that the outer part can better counteract static and mechanical stresses. The inner part can be made of a material of lower density, as it is less stressed statically and mechanically, whereby the cladding element can be carried out more easily than at the same height throughout.

Preferably, the cladding element is made of a foamed plastic, for example polystyrene, preferably made of expanded polystyrene.

It can be provided that both parts are made of polystyrene, for example, the outer part may be formed of a polystyrene higher strength.

It can also be provided that the outer part is made of, for example, a polyurethane foam, which is fire-resistant, so that the cladding element is fire-resistant, while the inner part may be made of polystyrene.

The cladding element is preferably used as an insulating element for a building wall.

Typically, a cladding element according to the invention has perforations which all have the same diameter. These holes are usually filled with no material.

However, it can also be provided that are provided by the wall-side boundary surface extending into the at least one cavity perforations with different diameters.

If the cladding element is not sufficiently open to diffusion despite the perforations, the perforations can in principle be increased in diameter or a mixed structure of perforations with diameters of different sizes can be provided.

In an advantageous embodiment, it is provided that exactly two different diameters are provided for perforations. It is then in the Panel provided a number of perforations with a small diameter and a number of perforations with a larger, preferably significantly larger diameter.

So that the insulating properties of the cladding element or the inner part of the cladding element does not suffer, it is provided that at least some of the perforations are filled with an insulating material, preferably with mineral wool.

Preferably, it is provided that at least those holes, which have the smallest diameter, have no filling with an insulating material.

In particular, therefore, the perforations are filled with a larger diameter with an insulating material, while holes with a smaller diameter are not filled.

If only holes with a larger diameter are provided, these are preferably filled with an insulating material.

An inventive cladding element described above is preferably provided and suitable for cladding the outside of a building.

FIG. 1 shows a trim element 1 according to the invention for covering a wall of a building. The cladding element 1 preferably serves as an insulating element for the wall or the building, a corresponding wall cladding or building cladding is formed from one above the other and laterally juxtaposed, immediately adjacent cladding elements.

The cladding element 1 has a two-part construction and consists of a building-side inner part 8 and a building-facing outer part 9. The inner part 8 and the outer part 9 are spaced apart by spacers 10 and interconnected, so that between the two parts 8, 9 and thus between the inner, wall-side boundary surface 2 of the cladding element 1 (which is the outer surface of the inner part 8 in the assembled state of the cladding element 1) and an outer wall facing away boundary surface 3 of the cladding element 1 (which in the assembled state of the cladding element 1 is the outer surface of the outer part 9) Cavity 6 is formed.

By arranging the spacers 10, the cavity 6 extends from the lower boundary surface 4 of the cladding element 1 to the upper cladding surface 5 of the cladding element 1 in the installation position of the cladding element 1 (i.e., in the layer in which the cladding element is attached to the building wall).

FIG. 1a shows a section of a cladding element 1 from FIG. 1 , As in the FIGS. 1a and 2 - 4 the spacers 10 are shown in the form of projecting from the outer part 9, for example, as shown in the form of circular cylinder stumps formed Extensions designed, see in particular FIG. 3 and FIG. 4 , The spacers, also referred to below as nubs 10, widen in the representation shown here toward the outer part, ie, the cross-sectional area of the nubs 10 on the outer part 9 is greater than its support surface 10 'facing away from the outer part 9. However, nubs 10 that are cylindrical are simpler in production.

The support surfaces 10 'are preferably flat and extend in the assembled state parallel to the outer part 9 facing outer surface 2' of the inner part eighth

These extensions or nubs 10 are formed integrally with the outer part 9 and are perpendicular from the inner surface 9 'of the outer part 9 from. Preferably, the nubs 10 are evenly distributed over the inner surface 9 'and have identical shape and dimensions.

In the assembled state, the knobs 10 lie with their bearing surfaces 10 ', for example on the outer surface 2' of the inner part 8 (not shown in the figures). The attachment of the two parts 8, 9 together preferably takes place by means of gluing.

In a preferred embodiment as shown in the figures and in particular in FIG. 4 can be clearly seen on the outer surface 2 'of the inner part 8 recesses 8' are provided, in which the studs 10 of the outer part 9 during assembly of the two parts 8, 9 are used. The knobs 10 are glued in the recesses 8 'with the inner part 8. Through the recesses 8 'results on the one hand a larger adhesive surface than in a gluing directly on the outer surface 2' of the inner part 8, on the other hand, this embodiment provides a transverse thrust insurance between the outer part 9 and inner part. 8

To connect the studs 10 with the inner part 8 in this case, adhesive can be applied directly to the studded surface 10 ', and / or it is provided that the adhesive is introduced directly into the depressions 8' and then the studs 10 in the wells eighth 'be used.

In another variant of the gluing is provided that, as shown in the figures on the outer part 9 mounting holes 13 are provided (see FIGS. 1 . 4 ), which extend from the wall facing away boundary surface 3 by the spacers 10th extend through the outer part 9 therethrough. About this mounting holes 13 of the inner part 8 and the outer part 9 can be connected to each other by externally, during assembly of the inner part 8 and the outer part 9, through the mounting holes 13 through adhesive into the recesses 8 ', ie between the studs 10 and the Inner part 8, is injected into the recesses 8 ', preferably just before the knobs 10 are moved into the recesses 8'. If the adhesive is introduced or even during the introduction of the adhesive, the knobs 10 are moved into their final position, in which they are present with the surfaces 10 'at the bottom of the recesses 8'.

The attachment holes 13 are, for example, bores which are drilled into the finished outer part 9, or the attachment holes 13 are already produced during the manufacturing process of the outer part 9.

The knobs 10, which are typically formed as circular truncated stumps as already described and whose circular cross sections decrease over their height (as they progress along the height away from the outer part 9), have diameters over the height which correspond to the diameter of the recesses 8 '. are adapted so that the knobs 10 can be sufficiently deep into the recesses 8 'used so that the stop surface 10' of the knobs 10 at the bottom of the recesses 8 'is present.

In a typical embodiment, the recesses 8 'have a diameter of about 65 mm, the knobs 10 have a diameter of about 60 mm at their support surface 10'.

The diameter of the support surface 10 'of the studs 10 preferably corresponds to the diameter of a plate 20' of a dowel 20, such a dowel 20 is in FIG. 2 shown. Typical dowels for fixing cladding elements such as insulation boards to a building have a plate diameter of 60 mm. Such dowels 20 serve to dowel the cladding elements 1 with the wall of a building, as in certain cases of advantage, preferred or required by law. The dowel 20 passes through the entire cladding element 1 preferably through the mounting holes 13 therethrough. Preferably, the inner part in the recesses 8 'further, subsequent to the mounting holes 13 holes 13' (not with the Cavity 6 are in communication), through which the dowel 20 is pushed into the wall.

Preferably, the perforations 13, 13 'have a diameter which corresponds to the actual anchor diameter (not the diameter of the anchor plate) or is slightly larger, so that the anchor can be easily inserted through the cladding element 1.

The diameter of the support surface 10 'of the knobs further corresponds approximately to the diameter of the plate 20' of a dowel in order to exert an optimal transfer of the holding force of the dowel 20 on the cladding element 1.

The dowels 20 are inserted for the reason through the mounting holes 13 through the cladding element 1, since it is reliably avoided in this way that the dowels 20 pass through the cavity or 6, where the cladding element is structurally weaker.

Due to the configuration of the spacers in the form of discrete nubs 10 de facto the entire space between the inner part 8 and outer part 9, with the exception of the space occupied by the studs 10, a large cavity 6, extending from the lower boundary surface 4 to the upper boundary surface 5 of the cladding element extends. Furthermore, the cavity 6 also extends from one lateral boundary surface to the other lateral boundary surface.

The FIGS. 1a . 2 - 4 in each case only show sections of a cladding element, in these cut-outs the knobs 10 reach up to the (cutting) edge visible in the figures or beyond. However, the nubs are to the actual, the fairing elements spaced edges (lower edge 4, upper edge 5, side edges, see FIG. 1 ), ie the outermost knobs do not reach all the way to the edge of the cladding element, in order to prevent that in case of unfavorable laying of the cladding elements, the connection between the cavities of two adjacent cladding elements is closed. Typically, the knobs have a distance to the edge of about 1 cm - 2.5 cm (normal distance from the edge of the nearest edge portion of a knob).

Like that FIGS. 1a . 2 - 4 it can be seen further, the lining element 1 has on its inner part 8 via a number of perforations 7, which pass through the inner part 8 starting at the boundary surface 2 on the wall side to the outer surface 2 facing the outer part 9 and extend correspondingly into the cavity 6 , Through these through-holes 7, which are preferably normal to the boundary surface 2, passes water vapor from the building wall into the cavity 6 and can ascend in this upward. The water vapor passes from a cladding element in the cavity 6 of the overlying cladding element until it finally exits the top cladding elements in the top of the building and is thus removed from the building.

The holes 7 are generated either directly in the production of the inner part 8 and subsequently attached in the form of holes.

A typical cladding element has a width of about 100 cm, a height of about 50 cm and a thickness of about 8 cm - 30 cm. On the surface of about 100 cm x 50 cm, less occupied by the knobs or the wells 8 surface, about 200 - 1500, for example, about 1200 through holes 7 are arranged.

The diameters of the holes 7 shown are in a specific embodiment about 2 mm - 4 mm.

The holes 7 are advantageously evenly distributed over the width and height of the cladding element 1 and arranged such that they always open into the cavity 6. In this way, the water vapor over the entire surface of the cladding element can be dissipated uniformly.

Regions of the inner part 8, which abut in the assembled state of the cladding element on the knobs 10, but are preferably free of perforations.

In general, those areas of the inner part to which spacers come to rest, are free of through holes 7, which connect the wall-side region with the cavity (s).

It is particularly advantageous if the inner part 8 and the outer part 9 have different strength, wherein preferably the outer part 9 has a higher strength than the inner part 8.

A higher strength of the outer part, so a higher density of the material used in the outer part has the advantage that the outer part can better counteract static and mechanical stresses. The inner part can be made of a material of lower density, as it is less stressed statically and mechanically, whereby the cladding element can be carried out more easily than at the same height throughout. Thus, a lightweight, stable trim element will be provided which optimally provides rear ventilation.

Preferably, the cladding element is made of a foamed plastic, for example polystyrene, preferably made of expanded polystyrene.

Both parts 8, 9 are made of polystyrene, wherein the outer part 9 may preferably consist of a polystyrene with higher density.

Expanded polystyrene (EPS), for example, has good thermal insulation properties, is cheap, rot-resistant and resistant to vermin. However, EPS is relatively diffusion-tight, typical values for the diffusion value of EPS are mü = 55-60. Through the through holes 7, the diffusion value of the inner part 8 can be reduced to a value mü of less than or equal to 15, so that water vapor passes well through the inner part 8 can diffuse without significantly affecting the EPS properties described above.

Once again FIG. 1 Coming back is further provided with advantage that on the wall facing away boundary surface 3, a structure in the form of one or more recesses 11 is provided.

These recesses are provided, for example, in the form of elongate incisions, which overlap somewhat in a honeycomb arrangement, on the outer side 3 of the cladding element 1 and lead to a better adhesion of a filling, to which, as described initially the outer plaster 12 is applied.

In the plaster layer, it is of minor importance, whether this is open to diffusion or not, since the water vapor is dissipated in the first place on the or the cavities in the cladding elements and not on the outer boundary surface 3 of the cladding element first

Recesses as described above are preferably also on the wall facing surface 2 of the cladding element provided (not shown), so that the adhesive or adhesive mortar for securing the cladding element 1 adheres to a building better.

Another variant of the invention is in the FIGS. 5 and 6 shown. This differs from the embodiment discussed above only in that not a large cavity 6 is provided, but that the spacers 10 as a continuous, extending from the upper boundary surface 5 to the lower boundary surface 4, preferably straight webs 10 are formed. In this way, continuous, from top to bottom, vertical channels 6 are formed, which are separated from each other by the spacers 10. A horizontal connection of the channels, in the form of openings (not shown) is also possible and then already leads back to the embodiment described above. The channels can in principle also be formed slightly inclined, but should extend from the lower to the upper boundary surface. Through holes 7 extend in turn on the inner part 8 of the surface 2 to the cavities 6. Through holes 7 are provided only in the areas between the spacers 10, areas with spacers 10 are free of through holes. 7

FIG. 7 and FIG. 8 Finally show a section of a cladding element, which is essentially that cladding element, as in the FIGS. 1a . 2 - 4 is shown corresponds.

That in the FIGS. 1a . 2 - 4 shown cladding element has a number of perforations 7 with a small diameter of about 2 mm - 4mm. These holes are empty, so filled with no (insulation) material.

In addition to are in the cladding element FIGS. 7 and 8 on the inner part even more, from the wall-side boundary surface 2 to at least one Cavity 6 extending perforations 7 'provided with a larger diameter. A typical diameter for these larger holes 7 'is about 30mm.

So that the insulating properties of the cladding element or the inner part of the cladding element does not suffer, it is provided that the perforations 7 'with a larger diameter an insulating material, preferably filled with mineral wool.

In a variant not shown further variant only larger perforations, filled with insulating material, such as mineral wool provided.
