Description

Arrangement for the production of a wall cladding or a floor covering

The invention relates to an arrangement for producing a liquid-tight

Wall covering or a floor covering. Furthermore, the invention relates to a covering plate for producing a liquid-tight surface.

Covering plates in the context of this description can be used as lightweight panels or as

Be designed decorative frame panels.

Lightweight panels in sandwich construction, in which between two carrier layers

Lightweight construction, such as foam material or honeycomb elements is arranged, are often used for covering flat surfaces, in particular of walls or floors, since they can be installed quickly due to their low weight in large-scale elements. Especially for wall elements, and here in particular for

Wall elements in wet areas such as bathrooms, is for the customer a durable and reliable waterproof quick installation with a visually appealing surface an essential selection criterion. For this purpose, the individual elements must be connected to each other, for which purpose different connection systems are known.

It is known, for example, the lightweight panels with holding elements, which can be produced, for example, as extruded profiles, to grip from the outside. However, it must be taken into account that the holding elements on the of the

Lightweight panels formed plane protrudes, so that no completely flat surface is formed.

Alternatively, it is known to design the lightweight panels so that at their edge surfaces respectively corresponding structures arise over which the lightweight panels can be inserted or locked into each other. However, such a compound is not regularly liquid-tight and can not withstand greater mechanical loads.

In contrast, the document US 3823525 Bl describes a liquid-tight

Connection system for lightweight panels, in which U-shaped profiles are inserted into the lightweight panels along the side edge, with one profile upwards and one downwards open, so that the legs can be inserted into each other and the gap between the legs then with an expanding

CONFIRMATION COPY Foam is filled. Through the expansion lightweight panels are pressed against each other sealingly.

It is known to use tiles for covering floors or walls, by individually glued on a flat surface and the joints are then filled with grout. This process is complex and requires a high degree of craftsmanship in order to achieve a permanently and reliably sealing and visually perfect surface.

Therefore, systems have been developed in which the tiles are already prefabricated so that they can be easily laid and sealed by a layman.

For example, document WO02002 / 31290 A2 describes a covering plate for installation in enclosed spaces, the covering plate having a decorative plate and a supporting plate foamed or glued thereto, which have the same dimension but are displaced relative to one another in such a way that the supporting plate is positioned on two sides under the

Decorative plate protrudes. On the other two sides the decorative plate protrudes over the

Support plate out. When laying the support plate engages each under the decorative plate of the adjacent plate. The edge structure of the support plate can engage in a suitably shaped corresponding edge structure of the adjacent plate into it and enter there a plugging or latching connection. The visual appearance of the installed decorative panel largely corresponds to that of conventionally individual laid tiles. In order to achieve a watertight suitable, watertight lining, the support plates must seal without further measures at their abutting surfaces reliably. This is not always the case in reality, but it requires at least a very precise one

Laying. In addition, a high cost of materials and thus an increased total weight of the lining plate is connected by the support plate.

Furthermore, the company Natursteinwerk Rinsche offers under the name of click and stone (www.click-and-stone.com), a laying system for natural stone slabs, in which the plates are connected by means of a joint profile. This must be in the

Natural stone slabs are milled a circumferential groove consuming, in which the joint profile is used. Furthermore, a natural stone slab with a thickness of at least 18 mm is required. In the light of these known solutions, it is an object of this invention to provide an arrangement for liquid-tight connection between covering plates, the layman simple and without tools for the production of a completely flat surface of covering plates

can be used.

This object is achieved by an arrangement having the features of independent claim 1. Advantageous embodiments of the invention are described in the dependent claims. Furthermore, the object is achieved by a plate having the features of independent claim 8.

An inventive arrangement for producing a liquid-tight

Wall covering or a floor covering comprises two covering plates, in particular

Intermediate layer is arranged, wherein along at least one plate edge, a profile is inserted into a recess in the intermediate layer and firmly connected to two carrier layers. Alternatively, the covering plate may also be formed as a decorative frame plate by a closed frame, formed from interconnected extruded profiles (2), and at least one decorative plate, wherein the at least one decorative plate is fixedly connected to the frame and sealingly covers a surface encompassed by the frame. The profile has at least one, preferably two mutually opposite latching legs. A spring has on opposite sides in each case a latching lug, which is designed for latching connection with a respective latching leg of the plates, wherein the spring is arranged on at least one side between the latching lugs

Middle section has a firmly connected to this sealing structure made of soft plastic, so that when both sides detent the spring in each case one of the lining plates, the sealing structure is pressed sealingly against the profiles of both plates.

In one embodiment of the covering plate as lightweight board, in particular when using the covering plate as floor covering, the carrier layers of the lightweight panels are preferably formed of mechanically resilient material, such as aluminum or synthetic resin, while the intermediate layer of a material with low specific gravity, such as a foamed plastic, a Honeycomb structure is formed with extending between the support layers struts or the like. The carrier layers and the intermediate layer are firmly connected to each other, so that the composite material has a high mechanical strength and low weight.

The recess in the intermediate layer can already be provided in the production of lightweight panels or intermediate layer can be removed up to a designated depth between the carrier layers in the edge region of the lightweight panels. The profile can be firmly connected in this recess, for example by gluing with the carrier layers. Particularly suitable as a profile is an extruded profiles, wherein the

Extruded profiles preferably made of aluminum.

In an advantageous embodiment of the invention, the profile has two opposite locking legs, in which engages a double-sided locking lug of the spring.

Preferably, the spring has two on an upper side and a lower side of the

Middle section arranged sealing structures made of Weichkunstsoff. These sealing structures are called so-called 2K material in the material of the spring when creating

embedded. The sealing structures may have sealing lips which are pressed against the profiles of both plates when the spring is inserted into the profiles detent. Alternatively, it is conceivable that a sealing bead is used instead of sealing lips, which also act by pressing against the two profiles of the lightweight panels sealing when the spring is inserted into the profiles detent.

In an advantageous embodiment of the spring, the sealing structure is formed exclusively on one side with a web-like projection which at least partially fills a region between the lining plates in a latching position of the spring and forms a closed surface with the lining plates.

To produce a desired visual appearance may be on one of

Carrier layers continue to be arranged a decorative layer. Especially when using the arrangement according to the invention as a floor covering, the decorative layer may in particular be a ceramic layer. The ceramic layer can be made relatively thin, since the mechanical strength is provided by the lightweight panels. But it is also conceivable that one of the carrier layers is used as a decorative layer. Particularly in the case of a carrier layer of aluminum, the decorative layer can be designed by printing the aluminum carrier layer. In a particularly preferred embodiment, the profile is designed with lugs that form a shock protection of the plate edge. The tabs are located at the end of the profile that protrudes from the recess above the carrier layers. This allows the

Lightweight panels are protected against damage before laying or during installation. When the spring is inserted into the profiles snap, the profiles of the two lightweight panels are pressed against the noses against each other.

In another aspect of the invention is a plate for making a

liquid-tight surface constructed as a sandwich of two carrier layers, between which a lightweight layer is arranged. Along at least one plate edge is a profile, preferably made of aluminum, inserted into a recess in the lightweight layer and is firmly connected to two carrier layers. The profile has at least one latching structure. Preferably, the recess is circumferentially present on all plate edges and on all plate edges a profile is inserted into the recess. Again, the profile may be equipped with lugs that form a shock protection of the plate edges.

As already mentioned above, a decorative layer can furthermore be arranged on one of the carrier layers to produce a desired optical appearance. Especially when using the plate according to the invention as part of a floor covering, the decorative layer may in particular be a ceramic layer. The ceramic layer can be made relatively thin, since the mechanical strength of the lightweight panels

provided. But it is also conceivable that one of the carrier layers is used as a decorative layer. Particularly in the case of a carrier layer of aluminum, the decorative layer can be designed by printing the aluminum carrier layer.

In one embodiment of the covering plate as a decorative frame plate, this has a

closed frame, which is formed from interconnected extruded profiles, which are preferably made of aluminum or plastic. A decorative panel is fixedly connected to the frame and seals a surface encompassed by the frame. The firm connection with the frame can be made by gluing, also over an encircling

Tape, or foaming can be realized. Alternatively, a film can be stretched on the frame and the decorative plate is glued to this film. In all cases, creates a sealing circumferential connection between the decorative plate and the frame. The

External dimensions of the frame largely correspond to the outer dimensions of the decorative plate, so that the frame does not or only slightly over the decorative plate. For example, it is conceivable that the frame has on its outer side a small nose, which acts as a shock protection for the not yet installed decorative plate and at the same time allows precise positioning of the decorative plate on the frame when firmly connected.

When laying a floor covering or a wall cladding by means of covering plates according to the invention, these can be connected together with springs as connecting elements which are shaped such that they engage in the extruded profiles of the covering plates and position and fix them at a desired distance from one another and at the same height. The fasteners can with a

Substructure be connected fixing, which also compensates for any unevenness in the ground or wall.

After laying the covering plates, the joints between them with

commercially available grout or be filled with silicone, so that the floor covering or the wall cladding has the same visual appearance as a conventionally and expertly tiled surface. But it is also conceivable that the joint is filled by a joint strand, which is inserted into the joint, the joint strand advantageously in suitable latching structures which are attached to the spring, is clipped, so that it is reliably held in the joint at But it can also be easily removed. Alternatively, the spring may already contain the joint strand, for example as part of the sealing structure made of plastic, which protrudes from the spring on one side. Of course, a design is conceivable in which the gap remains unfilled.

Preferably, the extruded profile of the lining panel according to the invention along an outer edge of the frame has a latching structure, via which two lining plates can be connected to each other by means of a spring engaging in the latching structure. If a fluid-tight connection between the lining plates is desired, the spring extends along the entire latching structure of the extruded profile and advantageously has sealing lips. For example, the spring may be made of plastic such as PVC, polyurethane or the like, and the sealing lips may be firmly embedded in the spring as so-called 2K material. When the spring engages in the extruded profiles, the sealing lips against the

Extruded extruded profiles and thus form a circumferential sealing line between the spring and extruded profile. If the floor covering or the wall paneling is to be made liquid-permeable, only two short spring elements can be provided instead of extending over the entire edge length spring, which in particular latching in the

Intervene extruded profiles and define a distance between adjacent ceramic surface elements. These individual spring elements can preferably be attached to the corners of the frame. Of course, more than two spring elements along an edge length of the frame can be arranged.

In an advantageous embodiment of the invention is on the frame formed by the extruded profiles not only a single decorative plate, but a plurality of

Decorative panels applied. For this purpose, the frame further on cross struts, which are underlaid the joints between adjacent decorative panels. The decorative panels are firmly connected by gluing or foaming with the cross braces as well as with the frame. In an advantageous embodiment, the cross struts each have a nose over which a desired joint spacing between adjacent decorative panels is provided. The cross struts are firmly connected to the frame forming extruded profiles, for example by screwing, welding or gluing and this increase the same time the stability, in particular the torsional stiffness of the ceramic

Sheet.

In one embodiment of the invention, the decorative plate as an aluminum plate, in particular as a printed aluminum plate, as a glass plate, in particular as a colored glass plate, as

High pressure laminate (HPL) or as acrylic sheet. These materials are particularly suitable when using the covering plate according to the invention as a wall cladding and allow a diverse design of the wall surface at a relatively low weight.

If the covering panel according to the invention is used as a floor covering, it is suitable as

Decorative plate, in particular a ceramic plate. Preferably, the ceramic plate has a thickness between 3 mm and 20 mm. A thickness of 9 mm is usually sufficient to sufficient mechanical strength, for example, by committing a

To ensure flooring. The use of a ceramic plate as a decorative plate is not limited to a use of the covering plate as a floor covering, wherein the Ceramic plate when used as a wall cladding can be made thinner than 9 mm.

The frame and thus the ceramic surface element advantageously has a first edge length between 15 cm and 120 cm and a second edge length between 80 cm and 260 cm. Even when using the upper limits of the respective edge length a good handling of the decorative frame plate is given, as this still has a weight that can be handled during installation.
