Panel for interior fitting and pressed sheet for producing a panel for interior fitting

Technical area

The invention relates to a panel for interior fitting according to the preamble of claim 1 and to a pressed sheet for producing an interior fitting panel.

In the field of interior design, it is common to create partition walls or cladding of wall or roof surfaces using relatively large-format panels, for example made of plasterboard. Such panels are attached to supporting structures, for example in the form of metal profiles or in the form of substructure battens. Since such panels form the base for the actual wall covering, a large number of work steps are required to create the final surface of the wall covering. In this context, wall covering is understood to be the surface visible to the occupant of a room. This can be, for example, plaster, tiles or wallpaper.

State of the art

A common method for forming a partition wall or a panel using a panel according to the preamble of claim 1, which is known as a prior use object, essentially requires the following steps. The panels are first attached adjacent to one another on the support structure described. The abutting edges of the panels have a groove to create a transition that is as inconspicuous as possible. In particular, the panels are bevelled at the edge so that a comparatively flat groove is created at the abutting edge. This groove can be filled with filler. Textile strips are then usually placed over the abutment point in order to connect the panels to one another in a tensile manner and prevent later cracks in the wallpaper.

The panels usually consist of a core material, for example based on gypsum or similar, and their surface is covered with a layer, for example a layer of paper. Before the wall or ceiling covering, made up of several panels, can be wallpapered, this surface layer of paper must be pre-treated with an impregnating solution. The wallpaper strips are then applied with wallpaper paste and finally the wallpaper can be painted over.

Handling the various tools to create a finished wall and ceiling covering is therefore very time-consuming and labor-intensive. Another disadvantage is that a large number of materials have to be purchased, and experience shows that there are leftover quantities of each of these materials that have to be disposed of.

Description of the invention

The invention is based on the object of simplifying interior construction and speeding up the completion of wall and ceiling cladding with an attractive appearance for the user, as well as enabling the user to dispose of as few residual materials as possible, in particular different residual materials. Furthermore, an aid for producing such an interior construction panel is to be created.

This object is achieved on the one hand by the plate described in claim 1 and on the other hand by the press plate described in claim 11.

Accordingly, the interior finishing panel according to the invention has a surface that is provided with the typical surface structure of a hand-crafted wall covering, in particular with its projections and depressions. Examples of such a hand-crafted wall covering that is already formed in the factory on the interior finishing panel according to the invention include wallpaper, a plaster surface or a surface that is created using a painting technique. As is readily apparent, such surfaces that are to be formed on existing walls or cladding, for example made of plasterboard, must be produced using a large number of individual processing steps. The creation of such a wall covering is also associated with considerable soiling and with the necessary disposal of numerous different individual materials.

The invention provides the significant advantage that such a surface structure is already present on a panel for interior fitting. In order to create a partition wall

or to create a panel with a corresponding appearance, it is only necessary to attach several panels next to one another. No rework, in particular filling, plastering or the work processes involved in wallpapering and painting, are required. With regard to a seamless connection between two panels and a suitable attachment to a supporting structure, reference is made to the application filed on the same day with the title "Panel for interior fitting and method for creating new walls in a room or for covering existing surfaces in a room". The measures specified therein enable interior fitting panels according to the invention, which can have dimensions of up to about 65 cm wide and a height of up to 2.60 m, to be connected to one another seamlessly. Consequently, the appearance of a partition wall or panel produced using the interior fitting panel according to the invention also meets the requirements from this point of view and at most leads to joints such as those known and accepted as abutting edges of individual wallpaper strips.

It should also be noted that the surface of the panel according to the invention can advantageously be designed in such a way that it can be painted with a conventional color. This means that a different color can be used at a later date if the user so desires, as is usual for hand-made wallpaper coverings. All structures that are possible and usual for the inside of rooms are conceivable as surface structures that can be provided on the panel according to the invention. For example, a suitable structure can be used to create an appearance that corresponds to that of plastered walls. Furthermore, any structures that are known from wallpaper can be provided. For example, a woodchip look can be created. Furthermore,

Glass fiber mats are known from wallpapers, which are essentially formed by a relatively coarse fabric. The resulting structure can also be provided on the surface of the panel according to the invention. This applies equally to glass fiber nets. Regardless of the specific design of the surface, the panel according to the invention results in a considerable simplification of interior construction because the attachment of the panel according to the invention means that numerous steps that were previously necessary for forming the final wall covering can be omitted. A tiled surface should also be mentioned as a hand-crafted surface that can be imitated by the panel according to the invention.

Advantageous further developments of the plate according to the invention are described in the further claims.

The panel according to the invention has a particularly attractive appearance when it has a color that also corresponds to a hand-crafted color. This is particularly intended for irregular coloring, such as that created using a wiping, rolling or sponge technique. In other words, in this way, complex and hand-crafted coloring of interior walls can be replaced by a corresponding factory-provided color on the panel according to the invention. The creation of a partition wall or the cladding of interior surfaces of a room therefore involves considerably less effort for the user, in particular an advantage in terms of assembly time and costs, and less dirt.

For the appearance of the plate according to the invention and in particular for the appearance of several adjacent plates, it offers advantages if the surface structure is irregular at least over the entire surface of a plate and preferably over the surface of several similar plates.

» &iacgr;: &udiagr; «' t- &psgr; * i

It is understood that the surface of the panel according to the invention is not merely created by repeatedly joining a certain, small-format surface structure. This would lead to a "rapport-like" appearance, which is recognizable even to the untrained observer. In contrast, for the panel according to the invention, it is preferred that the surface structure is irregular at least over the entire surface of a panel and thus repeats at most on an adjacent panel. However, the surface structure is preferably also irregular over several adjacent panels, which can be ensured, for example, by suitably large-format press plates in the context of the production of the panel according to the invention, as described in more detail below. In this case, the surface structure repeats itself after a sufficiently large distance, so that the impression of a repeat cannot arise under any circumstances. Rather, the impression is created of an irregular, hand-crafted surface structure. Alternatively or in addition to this, the front of the panel can also be colored in a different way. For example, in addition to the surface structure, the corresponding color can be provided, e.g. a tile pattern, a wood decor or the like. However, if necessary, only a coloured design of the front side can be provided, without a three-dimensional structure. In this case, the coloured design can either replicate the play of light and shadow of a three-dimensional structure or it can imitate the colour of an already smooth wall covering, for example the pattern of a decorative wallpaper.

For the susceptibility of the plate according to the invention to soiling and for the versatile use of the plate according to the invention, it has proven advantageous to provide the front of the plate with a surface seal that is resistant to moisture. The front can advantageously have a

have a moisture-repellent surface coating or surface seal, so that a particularly easy-care surface is created that can be easily maintained with damp cleaning agents.

Furthermore, it is preferred for the board to be made of a wood material, in particular MDF or HDF board, or, alternatively, of plastic. In these materials, the contours required for fastening two adjacent boards to one another and for fastening the individual board to a supporting structure can be formed with the necessary precision. Furthermore, the surface structure according to the invention can be formed particularly attractively on the surface of a wood material by pressing a paper or a film using melamine resin. In this way, on the one hand, inexpensive manufacture is guaranteed and, on the other hand, such boards can be attached without any problems. In addition, realistically simulated surfaces are known for such wood materials, for example in the form of laminate layers. Finally, such boards are highly resilient, since similar laminate panels are used as floor coverings, for example, so that the boards can be used as long-lasting wall or ceiling paneling without any further protective post-treatment.

The panels can advantageously be rectangular. A sealing material can be arranged on a long edge or on a long and a short edge, so that an elastic contact with the adjacent panel is possible, both on the adjacent panel in the longitudinal direction and in the transverse direction. In this way, slight movements, for example due to material expansion, are compensated for by the elastic sealing material deforming or relaxing, without resulting in open, clearly visible joints between adjacent panels.

panels. It should be mentioned that it is alternatively conceivable to allow or even emphasize a joint at this point. For example, such a joint can be allowed with an appearance that corresponds to the appearance of a wallpaper joint, so that this can be accepted and supports the impression that it is a hand-crafted wallpaper surface. Alternatively, the edges of the panel according to the invention can even be beveled so that an emphasized joint, for example a V-shaped channel, is created in the area of the joint, into which, for example, a colored joint material can be introduced so that the joints are emphasized and a correspondingly desired surface appearance is created.

Instead of the sealing material mentioned, it can be provided to apply adhesive to the panel so that a secure bond with the neighboring panels is achieved and gaping joints can be reliably avoided. To ensure that the adhesive can be handled easily and conveniently for the user, it can be provided to provide the adhesive with a cover strip that can be removed shortly before the panel is installed, or to use a two-component adhesive, with one component of this adhesive being arranged on opposite edges of the panel. Only when two panels are connected, when they are installed abutting against each other, do the two components of the adhesive combine and create the bond.

Although the tight and seamless connection between two adjacent panels can be ensured by suitable locking contours, in certain applications it offers advantages if two adjacent panels are alternatively or additionally connected to each other using an adhesive. In this case it offers advantages if in the area of the adjacent edges

a glue receiving channel is provided which is filled with glue when connected.

For an attractive appearance, it is also advantageous if there is a protective strip, in particular a self-adhesive protective strip, on the surface at least along edges to which adjacent panels are placed, which can then be removed when the connection between two adjacent panels is formed. In particular when adhesive is used, the surfaces of the panels are thus protected from contamination.

A further simplification for the user can be achieved by the preferred embodiment in which the back of the panel according to the invention is provided with an insulating material so that such a material does not have to be attached separately. This can be either a thermal insulation or a sound insulation material. For example, an acoustic or sound insulation mat with advantageous sound insulation properties can be attached to the back of the panel, which usually only needs to be a few millimeters thick to reduce structure-borne noise. Furthermore, an insulating mat, for example made of polystyrene or polyurethane with a thickness of, for example, 60 mm to 80 mm, can be provided for an advantageous reduction in the passage of sound and for thermal insulation. The thermal and sound insulation properties of the panel according to the invention can be influenced in this way.

The invention further provides a pressed sheet for producing a three-dimensional surface structure of a panel for interior construction, which is characterized in that the surface of the pressed sheet is irregularly designed with a repeat of at least 0.2m and/or a comparatively high degree of fineness. This means that the surface is irregularly designed with a very fine structure. This means that

a comparatively small area contains numerous elevations and depressions, as is the case with a plaster surface, for example, or a so-called painter's surface. In this case, the distance between a repeating, finely irregular surface structure does not necessarily have to be a certain size. In the alternative, in which the surface is formed by a coarser structure, it is necessary and provided according to the invention that the distance between repeating structural elements is at least 0.2 m in order to avoid a repeat-like appearance. This can ensure an irregular, hand-crafted appearance of the surface structure even on a larger area. In this context, it is particularly preferred that the surface of the pressed sheet is irregular over an area of at least 1 m × 0.3 m. The area mentioned is the smallest common area of a panel for interior construction, so that the measure according to the invention of making the surface of a pressed sheet irregular over such an area creates an irregular and not "repeat-like" surface structure at least for the individual panel. However, it is preferred that the surface structure of the press plate according to the invention is irregular over an even larger area, so that even larger plates with an irregular surface or even several plates produced next to each other can be provided with an irregular surface.

It should be noted in this context that the panel according to the invention is usually produced by pressing a decorative paper or another suitable film with a panel made of wood material, in particular HDF or MDF. Melamine resin is used here, which advantageously flows into the cavities that arise because the press plate used for this purpose has a recess. These recesses in the press plate

appear as elevations on the interior finishing panel produced in this way and, together with the remaining topography formed on the upper side of the panel, lead to a three-dimensional surface structure of the interior finishing panel according to the invention.

In accordance with the preferred embodiments of the panel according to the invention, it is preferred that the pressed sheet according to the invention has a surface structure that corresponds to the negative of a hand-crafted wall covering, in particular a wallpaper or plaster surface. As a result, interior finishing panels with the corresponding appearance can be produced, as explained above.

In order to better match the appearance of traditional wall coverings, the manufacturing process can provide for the use of decorative papers in the laminate that have the familiar appearance of a wall covering. In addition, the surface roughness of the laminate can also be influenced by using appropriately designed press plates, so that, for example, a topography of the plate surface that can be aligned to the interior can be achieved that is adapted to the topography of a wall covering or is modeled on it, e.g. a wallpaper or plaster surface.

The invention further proposes the use of a laminated raw panel, i.e. a raw panel made of a wood material, which has a surface made of a laminate and which has not yet been divided into panel sizes that can be sold to the end user. The use of such raw panels for the production of one-man panels for interior fitting, i.e. with the corresponding dimensions mentioned at the beginning, enables particularly rapid construction progress in interior fitting, since it provides a surface that is finished at the factory, so that the user does not have to add to the surface or

This is especially true if the edge design of the panels allows the panels to be locked together.

To better match the appearance of traditional wall coverings, decorative papers that have the familiar appearance of a wall covering can be used in the laminate. In addition, the surface roughness of the laminate of the raw panels can be influenced by using appropriately designed press plates, so that, for example, the raw panels can have a topography that is adapted to the topography of a wall covering or is modeled on it, e.g. a wallpaper or plaster surface.

Finally, the invention proposes a wall or ceiling covering for an interior consisting of several panels. This wall or ceiling covering can be produced particularly quickly by using panels with a factory-finished surface and causes the user to produce particularly small amounts of residual materials, in particular of different residual materials, compared to known wall or ceiling coverings.

In particular, the aforementioned panels with their previously described advantages can be used, as they can produce wall or ceiling cladding that is quick to install and highly durable.

Shrinkage within the panels or the supporting structure, for example due to moisture and/or temperature changes, can occur. It can therefore be advantageous to attach the individual panels to their supporting structure in a movable manner, i.e. to carry out a floating installation, so that, for example, material expansion of the supporting structure itself or the panels can take place without causing distortions or,

The plates are advantageously firmly connected to one another, for example by means of the aforementioned snap-in connections or adhesives.

If such a firm and play-free connection of the panels is not provided, any play between the panels can be compensated for using the sealing materials mentioned above. In this way, a smooth, closed surface is maintained without the possibility of gaping joints.

While the width of the individual panel elements from the floor area is a maximum of approx. 30 cm, the one-man panels provided according to the invention can have widths of over 60 cm. They can, for example, be dimensioned to match the usual size of wallpaper strips, so that - as already mentioned - the design of the abutting edges and any unevenness present there creates the same optical effect as the visible edges of wallpaper strips glued butt-to-butt.

For the panels provided according to the invention, a comparatively low degree of gloss of the surface can be provided. This can be achieved by appropriate design of the laminate, for example by using appropriate press plates. With such press plates, the top layer of the laminate is embossed in a manner known per se, so that the surface design and in particular the surface roughness can be influenced with the help of such press plates. Apart from the design of the press plates, the surface roughness of the panels and thus the surface roughness of the laminate layers can be influenced, for example, by the types of paper used, the degree of resin or, if necessary, by liquid or solid additives. For example,

coarser paper is used or the additives are added in the resin or in addition to the resin.

Such a higher surface roughness compared to floor coverings not only results in a visually desired, more matt surface of the panels, but also enables better adhesion of varnishes or paints. In this way, the individual panels or the entire ceiling or wall paneling can be painted over, either to influence the color immediately when the wall and ceiling paneling is created ¹ or to change the appearance of the wall or ceiling paneling after some time of use.

For the panels or wall and ceiling coverings according to the invention, it may be possible to make the panels breathable. For this purpose, for example, when producing the laminate layers, it may be possible to use a decorative paper with the desired color, which is coated with melamine resin, for example. The decorative paper can be printed with a substance that is visible or invisible depending on the desired pattern, which repels the subsequently applied melamine resin, so that an airtight seal that would otherwise be created by the melamine resin is interrupted at these points. Since the panels in the wall or ceiling area are usually not exposed to such strong moisture loads as in the floor area, such an interruption of the seal can be provided without adversely affecting the longevity of the panels or the wall and ceiling covering. In this way, a vapor-permeable wall and ceiling covering is made possible.

To achieve the largest possible uniform appearance, gaping joints between adjacent panels should be avoided. It can be advantageous to provide both

It is therefore advisable to use both adhesive and an edge design that allows adjacent panel elements to be locked together. The locking can be relatively weak, so that the panels can be easily connected to one another without having to overcome excessive pressing forces. If additional adhesive is used, the locking only has to hold the adjacent panels together until the adhesive has dried and the two panels are finally connected. The use of tensioning belts, as is known from practice when gluing panel elements, for example on floors, is thus superfluous, which promotes rapid work progress.

As an alternative to press plates, appropriately profiled rollers can be used. Achieving the appropriate roughness depth in the surface of the board material can be facilitated by using appropriate paper, for example when using a laminate as the board surface, for example a paper with a higher grammage than the usual basis weight of around 70 - 80 g per square meter, which is usual for an unresin-free base paper. In addition, additional layers can be used as so-called "underlays" to increase the compressibility of the surface layer of a laminate and thus enable particularly large roughness depths.

Advantageously, a panel according to the invention can be manufactured particularly inexpensively by simultaneously combining the various laminate layers of the known laminate surface on the one hand and the core on the other hand, which can consist of a wood material, for example, and thirdly a counter-pull material, such as the known counter-pull paper, to form a workpiece. This can be achieved in an energetically particularly favorable and accordingly inexpensive manner with a pressure of around 40 kp/qcm, so that the production of such

Laminate panels can be produced much more cost-effectively than the conventional production of HPL or CPL panels, where the laminate is first manufactured and then bonded to the core and the counter-pressure material under considerably higher pressure of around 70 kp/cm², i.e. in a second work step.
