Abstract

A wall or building facade cladding panel has a layer of hard foam in which ceramic tiles, stones or similar are embedded or bonded. The seams between adjacent tiles are accessible. The rear face of the panel esp. has an array of vertical and horizontal grooves that serve to equalise water vapour pressure and relieve stress caused by minor misalignment between adjacent interlocking panels. The grooves are 3 mm wide and 10 mm deep.

Description

The invention relates to a wall element for the cladding of facades or the like with embedded or incorporated in a layer of rigid foam Plates or stones, ceramics, Ziegelmiemchen or the like, in the the joints between plates with mortar or the like are available.

It is known to subsequently disguise houses with wall elements that the Appearance of masonry. However, such wall elements are difficult, for whole house walls the impression of a closed masonry to achieve. So that the individual wall elements and their attachment points can not be clearly recognized, it is known to arrange the plates so and form the hard foam layer carrying it so that at the vertical Edges of the wall panel panels along with their associated Part of the rigid foam layer carrying it alternately over a vertical Edge protrude and the towering panels of a vertical edge relative to the corresponding plates of the other opposite one another vertical edges are offset by about half a plate length, so that with two adjacent wall elements over the vertical Edge protruding plates of a wall element in between two engage outstanding plates formed gaps of the adjacent wall element and so a closed masonry with closed rigid foam layer form (DE 35 03 543 A1).

It is also known to achieve a predetermined, uniform, in particular planar surface of adjacent plates of the known arrangement the adjacent comb-like wall elements with groove and Spring to connect and in vertical and horizontal direction with each other to provide overlapping areas of the rigid foam layer (DE 92 13 076 U1).

The invention has for its object to improve the known wall elements. This object is achieved by the wall element characterized in claim 1 solved. Further developments of the invention are characterized in the subclaims.

In principle, the invention consists in that in a wall element with in a Layer of rigid foam embedded, incorporated or glued Plates or stones, straps or the like in the rear wall of the wall element Grooves are provided. The grooves serve essentially to compensate a vapor pressure and / or for surface relaxation. You can be arranged vertically, but is also a horizontal arrangement of the grooves or a combination of vertical and horizontal Creases are advantageous Also, oblique grooves or groove parts are advantageous usable.

In a further development are between the grooves on one side and in the Joints between the stones or plates on the other side spacer sleeves arranged, which penetrate the wall element and a fastening of the Allow wall element to the supporting wall, without the attachment to be pushed out of the wall element. The opening of the spacer sleeve is located in a joint between two adjacent panels behind a recess, the extends to the depth of the foamed spacer sleeve. These spacers have a hole penetrating the layer. The recess is through a appropriately sized foam piece closable. At the back These spacers end up on surfaces between the grooves, not in the area the grooves.

The invention provides a vapor pressure equalization and / or a surface relaxation achieved and thus moisture development and damage to the Wall element largely avoided. The grooves end at the edges of the Wall element in opposite the surface of the back recessed edge regions and thereby allow distribution of vapor pressure across adjacent ones Wall elements and possibly also beyond. Furthermore allow interconnectable or interlinkable elevations, Depressions as well as grooves and springs provide a lighter and safer connection of the adjacent wall elements and also better recognition of the done Connection of these wall elements.

FIG. 1 shows a wall element 1 with hard rock or ceramic plates 5 embedded in a hard foam layer 2, 3, referred to below as ceramic plates. These ceramic plates 5 have, for example, been embedded in this material during the production of the rigid foam material in a manner as described in DE 30 33 819 A1. This results in hard foam panels, which have a high thermal insulation and strength at the same time. The wall element 1 has upper and lower edges 1a and 1b, which are used to connect the wall element 1 with each above or below, similarly formed, not shown wall elements and have adapted tongue or groove or matched to each other elevations and depressions.

To use such wall elements 1 for the subsequent covering of Facades are several in the wall elements 1 at predetermined locations Spacers 9 provided with holes or holes 6, through which not shown Fixing screws to the pad, not shown, for example a facade, through which can be inserted. These holes 6, Holes or the like are arranged in joints 7 between the ceramic plates 5 and after fixing all wall elements 1, i. after Cladding of the facade, together with the joints 7 closed with mortar. In FIG. 1, the wall elements 1 are provided with very thick rigid foam layers 2 provided, for example, 80 mm. The holes 6 are at the foot of recesses 8 arranged before the mortar through appropriately adapted Foam pieces are closed to the screw against the Protect penetration of water. When using thinner rigid foam layers 2, the spacers can also end directly at the joints 7. The wall elements 1 may be on the base, for example a facade, be securely and evenly fastened without the screws in the Hard foam layers 2 can squeeze. For this purpose, the Holes 6 or the like with a wall of a solid, hard Surrounded by material. This wall is, for example, by spacers 9th formed with flange-like statements that between them Include rigid foam layers 2. These spacers 9 are in the Production of hard foam layers, ie under high heat, together with the ceramic plates 5 in one operation in the rigid foam embedded. The material for these spacers is a water vapor resistant, until, for example, 150 ° usable plastic used.

The ceramic plates 5 are sized and arranged so that ceramic plates. 5 the wall element 1 together with their respective associated rigid foam part of a wall element 1 as tines 4 in recesses 3 of the respectively adjacent wall element 1 engage and these recesses. 3 close.

Similarly, ceramic plates 5 of the respective adjacent wall element protrude 1 beyond the edge of this wall element 1 and engage in recesses 3 of the wall element 1 inside. When wall element 1, the recesses 3 by a rigid foam layer 3 of lesser thickness (D) deposited, which consists of the one piece with the layer 2. This layer 3 is in the places the recesses 3 thus formed thinner than the entire layer 2 + 3. The Layer 2 protrudes slightly beyond the plates 5 and thereby forms parts the joints 7 to the adjacent wall element. The layer 3 of reduced thickness (D) protrudes at the vertical and horizontal edges of the wall element 1 with an overlap strip 21 beyond the protruding parts. These projections 21 thus form an overlap zone in front of the comb-like projections. A wall element adjacent to the layer 2 of the wall element One-piece foam layer 3 of reduced thickness is under the over the edge of the wall member protruding ceramic plates 5 also thinner than the layer 2 + 3, in such a way that the ceramic plates 5 with its underlay in the deposited recesses 3 just fit. The one comb-like pad and embedding for the ceramic plates. 5 forming thinner layer also forms in front of the plates 5 parts of the joints. 7 In addition, this layer is in their source area to a on the End face perpendicular to the longitudinal direction of the ceramic plates 5 extending Surface shaped, which overlaps the projecting surface of the wall element 1 is trained. In this way, a heat bridge-free, dense fairing achieved without heat or cold bridges. In addition, this construction causes an outwardly even surface of all comb-like with each other connected wall elements 1 in the longitudinal direction of the ceramic plates. 5 The teeth thus obtained of the adjacent wall elements 1 with their overlapping areas After mortaring results in a uniform facade. By the comb-like formation and by the uniform overlapping surfaces 21 at the same time a guide of the wall elements 1, 2 in the process for their assembly reached.

FIG. 2 shows a rear view of the wall element 1 explained with reference to FIG. 1, in which grooves or depressions 10 are provided to clarify the illustration. These grooves 10 are about 3 mm deep and 10 mm wide and run in wesentntlichen in the vertical direction, ie perpendicular to the toothing 3, 4. The distances of the grooves 10 may be the same size, but is also an education, arrangement and frequency according to experience of Training of vapor pressure distributions or surface relaxation possible. The groove width and the groove depth can also be adapted to the requirements. At the horizontal edges 1 a, 1 b of the wall element 1, the grooves 10 terminate at areas 20, which are formed recessed relative to the surface 22 of the hard foam layer 2, as is made clear in Figure 4. These regions 20 can be used for connecting adjacent wall elements, but also for distributing the vapor pressure via one or more adjacent wall elements 1.

A similar arrangement of the grooves is in the top or bottom ago with the Wall element 1 connected similarly constructed wall elements provided. The grooves 10 of adjacent wall elements can each continue. But you can also be offset from each other.

FIG. 3 shows a view of the upper side of the horizontal edge of the wall element 1 in FIG. 2 with the overlapping regions of the rigid foam layer 2. In the overlapping regions 21, grooves 14 on the one hand and elongate projections 15 on the other hand are provided which enable a hooking of adjoining wall elements 1 , Superimposed wall elements 1 are preferably interconnected by grooves and springs, as indicated in Figure 4. They allow a slight assembly of those wall elements 1, which are inserted into the lower wall elements 1 and hooked into the already laid wall elements 1 side.

Figure 4 shows a side view of the wall element 1 on the vertical edge with the representation of groove 14 and spring 15 in the horizontal edge and with the recessed regions 20 for the vapor pressure distribution.

The depression of the regions 20 opposite the surface 22 may be the depth of the Grooves 10 correspond.

Figure 5 shows another embodiment of the back of the wall element 1 in Figure 1. Also in this figure 1 grooves are provided in the back of the wall element, but these grooves 11 are horizontal, ie in line with the teeth 3, 4. They too are shown at a distance. Recessed edge regions of the back 22 also provide for the distribution of Dampfdruchs on adjacent wall elements.

FIG. 6 shows a wall element with a combination of the grooves 10, 11 of FIGS. 2 and 4. Here, grooves 10 are shown with substantially vertical and / or grooves 11 with a substantially horizontal course 11. The grooves are partially continuous. The oblique arrangement of grooves 12 may be advantageous. Individual zones have interruptions 13, whereby, for example, the grooves 10, 11 are separated from each other or from the additional oblique grooves 12 by a collection or depression.

The wall elements 1 are at the parallel to the longitudinal direction of the stones 5 or the comb-like projections 3, 4 of the foam formed from rigid foam 2 with fasteners, for example, overlapping Strip 21 in the vertical direction and with springs or grooves along the one horizontal edge and with grooves or springs along the opposite horizontal edge of the respective wall element provided. The grooves and the Like the overlapping zones 21, springs interlock and stabilize both the connection on the long sides and at the transition from the Long edges to the transverse edges in the corner area.
