Wall cladding eiduiigs el omen t

The invention relates to a cladding element with a panel or. plate-shaped base, the main function of which is to give the entire cladding element the required stability and cohesion, and with a layer of a different material held on at least one surface of the base, the main function of which is to shape the decorative appearance that but can have other additional functions, such as weather protection and the like, _o

Cladding elements of this type are often called VJandverkloidungselemente used to cover house walls or other structures, but apart from thick main application, also as covering plaster and other protective elements are used.

The object of the invention is to provide a new and improved cladding element of the type specified at the outset, which has considerable possibilities for variation.

109885/1213 * «OR ₁ GlNAL

Handled for those in the formation of the decorative appearance embossing layer offers without making major changes to the manufacturing process for to condition the cladding element; This makes it possible to use the new cladding element in many different; Manufacture embodiments without high or increased production costs.

The lining element according to the invention is a layer from several solid, pre-formed bodies with these enclosing, powdery! or granular solid grout with the preformed bodies exposed on one side of the layer and a tabular or plate-shaped base is arranged. The underlay and the grouting material have a solidified binder soaked, which creates the cohesion between the base and the preformed bodies.

Each of the bodies is attached to the backing through the binder connected surface preferably flat. Each body can also be on the side facing away from the base be flat with the surface of the grout exposed between the bodies with either the exposed flat surfaces the body forms a plane or in a plane between the two flat surfaces (on that of the base facing and facing sides) the body forms a plane so that the grouting material forms the basis of a joint system the exposed surface of the cladding element.

In an alternative embodiment, those facing away from the base can Surfaces of the bodies have a raised or other non-planar shape, with the exposed surface of grout s lies between the bodies in one plane, v; el-

109885/1213 ORIGINAL BATHROOM

before between the protruding parts of the body and those with the base connected surfaces of the body is arranged.

All 'material for the body is available in a wide variety; However, the bodies are preferably formed from a ceramic or glass-like material or consist of in the IJatur occurring stones or pieces of rock.

In the following, exemplary embodiments of the invention are explained in more detail with reference to the drawing. In the drawing show:

Fig. 1-3 successive production stages of a Cladding element, the components of the cladding element and those during manufacture shape used are shown in vertical section view;

Fic ,. 4 is a vertical sectional view through two different ones Embodiments of the cladding element; and

Fi;:. 5 shows a plan view of the embodiments of the cladding element shown in sectional view in FIG. 4.

In the following, reference is first made to those shown in FIGS. 4 and 5 Embodiments of the cladding element received. 4 and 5 are on the left and on, respectively the right side shows two different embodiments, with the embodiments common components are provided with the same reference numerals. In both cases, the cladding element is panel-shaped or plate-shaped Base 10, which is formed from a fiberglass mat impregnated with polyester resin. Besides that, it shows Cladding element has a layer of preformed solid bodies or 12, which is supported on one side of the base 10 or are attached.

The bodies 12 are designed as plates and have flat surfaces 13, which is connected to the adjacent surface of the pad 10

109885/1213

stay in contact. The flat surfaces 14 of the body 12, which are exposed on the side facing away from the base and shape the decorative appearance of the cladding element, are aligned in a common plane.

The bodies 11 have an irregular shape and are in contact with the base via flat surfaces 15. At theirs Flat surfaces 15 opposite sides are generally raised or convex surfaces 16, parts of which exposed to the decorative appearance of the cladding element to coin.

The bodies 11 and 12 may be arranged in a regular or irregular pattern, _{or the like}

The bodies can be made of different materials. A particularly attractive appearance is achieved, for example, by achieved the use of ceramic material for the body. The bodies can have the same or different colors, and at least the exposed surfaces 14 and 16 can be coated with a glaze.

As an alternative, the bodies can be made of glass.

In yet another alternative embodiment, the body can be made of stone, the stones in the form of plates or Tables are present when the embodiment according to the right Representation in Fig. 4 is to be built, or consist of pebbles or lumps of stone, if the one in Fig. 4 on the left Page illustrated embodiment is to be formed.

The spaces between the bodies are grout filled, which is initially present as a powdery or granular material. The grouting material is, for example Sand particularly suitable. The grouting material is initially applied with the liquid binder, namely polyester resin,

109885/1213

which is used to soak the glass fibers forming the base 10, impregnated.

The binder or binder therefore has three different functions. The first function is that it is the underlay reinforced or stiffened and thereby makes them dimensionally stable, for example in the planar shape shown in FIG. 4 holds. The second function is that of an adhesive between the flat surfaces 13 and 15 of the bodies and those adjacent to them Surface of the pad. In addition, the binder acts to hold the particles of grout together and optionally between the lateral boundaries of the ribs formed by the grout and those in contact therewith standing surfaces of the bodies 11 and 12.

As can be seen on the right-hand side of FIG. 4, the exposed surfaces 18 of the grout 17 form a Level with the exposed flat surfaces 14 of the panels. Eg is easily possible in another embodiment that the Surfaces 18 below the plane formed by the exposed surfaces 14, namely between the two surfaces 13 and 14, are arranged «To achieve this arrangement, the penetration depth the impregnation material or binding agent in the grouting material during the production of the cladding element is controlled accordingly. In the case of the last one described Embodiment form the surfaces 18 the bottom or bottom of a Groove or channel system, the bodies 12 protruding outwardly.

In the embodiment shown on the left-hand side of FIG the grout is also soaked with the binder only to a controlled depth, with the exposed Surfaces 18 of the grouting material approximately plane-parallel and below the crests of the irregular or generally convex surfaces 16 are arranged

The base 10 preferably has peripheral flange parts 19. These can run along the entire perimeter of the pad

109885/1213

or along opposite sides of the pad. The base is usually square or rectangular, although other shapes can be used as desired. The flange parts 19 can be used as connecting parts serve to connect adjacent cladding elements. In addition, the flange parts give the possibility that two cladding elements be attached to each other with the backs facing each other, if a design is to be created, in which a decorative surface appears on each of the two opposite sides.

Because of the due to the structure of the cladding element Possibility of choosing from a variety of different bodies 11 and 12 made of different materials and different Colors, and to be able to choose from a variety of patterns or irregular arrangements, the cladding element can be produced in a large number of different forms, always the same Pad 10 and the same grouting material or filler material 17 can be used.

Accordingly, it is possible for many in terms of their external appearance different cladding elements to use the same manufacturing method and thereby the manufacturing process to make it economical and practical.

The sequence of a manufacturing process for the inventive Cladding element is shown in FIGS. 1 to 3, in which the individual components are consecutively given the same reference numerals are provided.

In this process, the bodies 11 and 12 are first placed in the desired positions on a removable base plate or Base 20 of a shape 21 set. The mold 21 has a peripheral wall 22 and is on the side opposite the bottom plate open minded.

109885/1213

The form is then filled with the filler or grouting material, e.g. with the sand 17, filled to the top, after which a removable cover plate 23 is placed on top of the mold no, that it is in contact with the sand surface.

The mold is then turned over (FIG. 3), whereupon the base plate 20, which is at the top in this position, is removed. Through this surfaces 13, 15 of the body 11 and 12, respectively, are exposed. The bodies are in the one that fills the spaces between the bodies Grout 17 embedded. The base 10, which is formed from a one-part or multi-part glass fiber mat can be, is placed on the exposed surface and along its circumference to form the flange 19 upwards succeeded. The flanges 19 are supported by brackets which are mounted on the upper flanges of the peripheral wall 22 of the mold are appropriate.

Liquid binding agent, for example a polyester resin, is then applied to the side of the base 10 which is at the top in this position and penetrates the substrate and grout to a controllable depth. The penetration depth is in the drawing by the cross-hatched areas 17 marked between the bodies. Setting the depth of penetration can be controlled by controlling the amount of binder applied, its composition (as far as the binder from two components which react chemically with one another to cure bst) or the temperature; in the latter In this case it is necessary to heat the mold together with its filling in order to accelerate the hardening of the binder.

As can be seen, up to the application of the liquid binder in all process stages only dry or solid substances is used, i.e. the bodies, the filling or grouting material and the underlay are formed in the dry state. That

109885/1213 ORIGINAL BATHROOM

Impregnation of the molding takes place selectively due to the fact that the underlay material and the grouting material are permeable, while the bodies are either impermeable or only in are permeable to a limited extent, e.g. in the boundary layer in contact with the substrate.

Accordingly, the liquid binder cannot flow onto the exposed surfaces 14 and 16 of the bodies and adversely affect their appearance. At the same time, an externally effective joint between neighboring bodies is achieved _r and the soaked joint material becomes impermeable to moisture as soon as the binding agent has set or has hardened »

Accordingly, the new facing member has good erosion resistance properties and is also resistant to adverse atmospheric conditions.

As is easy to see, the cladding element does not necessarily have to be plane-parallel. So the pad 10 be either convex or concave and optionally in one dimension or in dimensions at right angles to one another Have curvatures.

Such a curved design can be achieved by using a corresponding shaped bottom part 20 of the mold can be achieved. In this case it might be necessary to have a temporary effect Adhesive for holding the bodies 11 and 12 in the desired positions after they have been placed on the base 20 and to be used before filling the mold with grout.

Instead of producing the cladding element using the three-stage process sequence shown in FIGS. 1 and 2 If necessary, the bodies can also be wetted directly into a bed of grouting material, the Form is in the position shown in FIG.
