Abstract

A steel plate (10) with a rough and/or porous surface coating (11).

Description

Technical field

A first aspect of the invention relates to a steel plate with a rough and/or porous surface coating. In particular, said surface coating bears a print, which is applied especially by means of UV printing. Furthermore, the invention relates to a steel plate having, on a side facing away from the surface coating, a stabilizing layer at least 1 mm thick, preferably at least 2 mm thick, more preferably at least 3 mm thick, the stabilizing layer comprising a thermoplastic or thermosetting plastic or a resin, and thereby forming a steel composite plate (SCP), wherein optionally a further steel plate is arranged on the side of the stabilizing layer facing away from the first steel plate.

Another aspect of the invention relates to a modular system comprising the steel plate or SVP according to the invention for cladding, designing, and variably functionally using walls or free-form shapes such as canopies, domes, or columns, wall-like surfaces (for indoor and/or outdoor use; e.g., for straight or curved walls; e.g., a canopy), particularly in retail and public areas (e.g., supermarkets, retail stores, hotel lobbies, event spaces, trade fair and stage construction, operating rooms). The system further comprises associated wall decoration and/or wall functional elements, interchangeable, printed, flexible magnetic panels (magnetic sheets), and allows for temporary or seasonally variable design without dusty, noisy, or dirty renovation work.

State of the art

When redesigning communication and focal points in sales or service areas, tiles, wallpaper, foils, or permanently mounted panels are frequently used. Replacing such surfaces, including rounded or curved ones, regularly requires dismantling, filling, drying times, retiling, or re-adhesive work, resulting in downtime, noise, dust, and high installation costs. Furthermore, drill holes and uneven surfaces often remain after the removal of existing installations. (Magnetic) whiteboards or thin magnetic sheets are generally unsuitable for large-area, hygienic, and heavy-duty wall coverings because they either lack the necessary rigidity, do not offer a consistently high-quality surface finish (e.g., a tile-like appearance with matte and/or glossy areas), or are not designed to support heavy, freely positionable functional elements (shelves, TV units, poster pockets). Magnetic whiteboards or thin magnetic sheets typically have sealed and/or highly matte surfaces, which can be made wipeable by applying appropriate coatings such as varnishes or by treating the surface. The aim is to achieve a so-called dry-erase surface from which colored markings and markers can be easily removed without solvents or residue. Such surfaces are not printable due to insufficient adhesion.

Task

One objective of the invention is to provide a wall cladding and design system that enables quick, clean and cost-effective initial installation as well as, in particular, subsequent redesign (e.g., seasonal, campaign-related or due to product range changes), whereby drilling and plastering work is avoided, the substrate is largely independent and at the same time a high-quality, hygienic, permanently robust surface with freely positionable decorative and/or functional elements is provided.

Description of the invention

This problem is solved by a steel plate and a modular system with the features of the independent claims. Advantageous embodiments can be found in the respective dependent claims and the embodiments numbered herein.

The core of the invention is a steel plate with a rough and/or porous surface coating, which is thus magnetic and printable. Preferably, a print is applied to said surface coating, in particular by means of UV printing. One embodiment of the steel plate according to the invention is a rigid, magnetically active steel composite plate (SVP), which has a minimum thickness of 1 mm. The steel plate or the aforementioned SVP (Steel Composite Panel) must feature a motif (e.g., a printed tile pattern with matte and glossy elements) covering at least part of the surface, and in particular, covering the entire surface, and serve as a permanent substrate. Decorative and/or functional wall elements are reversibly attached to the steel plate or SVP using a magnet, the magnetic force preferably being designed with a safety factor and corresponding to at least five times the weight of the respective element. Additionally or alternatively, a multi-layered, flexible panel (BFP) is provided, comprising a ferritic layer in a first layer and a polymer layer bonded to it in a second layer, and serving as an interchangeable magnetic foil for design changes. The flexible panel (BFP) is designed to be magnetically attached to the steel plate or steel composite panel and, if necessary, removed or replaced without leaving any residue.

In the context of the present invention, the term "steel plate" describes a preferably one-piece steel plate with a rough and/or porous surface coating. In particular, said surface coating bears a print, which is applied especially by means of UV printing.

In the context of the present invention, the term "steel composite plate" describes a steel plate as defined above, but additionally comprising on one side facing away from the surface coating a stabilizing layer at least 1 mm thick, preferably at least 2 mm thick, more preferably at least 3 mm thick, the stabilizing layer comprising a thermoplastic or thermosetting plastic or a resin, thereby forming a steel composite plate (SCP), wherein optionally a further steel plate is arranged on the side of the stabilizing layer facing away from the first steel plate. The SCP is designed to be rigid in itself.

Detailed description of the invention

Basic structure of the steel plate

The steel plate (10) is preferably a one-piece steel plate with a rough and/or porous surface coating (11). According to the invention, the steel plate (10) thus has a highly adhesive surface, which is created in particular by the surface coating. This makes the steel plate (10) printable according to the invention. This offers the advantage that the steel plate has improved surface adhesion due to the presence of roughness and/or porosity, in contrast to otherwise sealed, e.g., high-gloss lacquered, surfaces of whiteboards, especially magnetic whiteboards of the prior art. According to the invention, no adhesion-reducing layer, such as dry-erase top coatings, is applied to the steel plate. In particular, no melamine, lacquer, enamel, or glass layers are applied to the steel plate according to the invention. In this context, "applied" is understood to mean a direct, in particular form-fitting and/or material-bonded, arrangement of layers. The steel plate according to the invention has a thickness of 0.1 to 0.9 mm, more preferably 0.2 to 0.7 mm, and even more preferably 0.3 to 0.5 mm. The rough and/or porous surface coating can, for example, be a white, matte, printable film that is (press-)laminated onto the steel plate. The print on the surface coating can therefore be a permanent print in one embodiment.

In this context, "printable" means that a coating applied by means of printing, inkjet, laser or, for example, UV printing remains on the surface, does not run and is permanently bonded to it after drying.

The preferred thickness of the steel plate results in a flexible design, which is particularly suitable for cladding non-planar surfaces, thus allowing, for example, rounded or curved surfaces/walls to be individually and interchangeably designed or clad. Surfaces of a canopy would be examples of such rounded or curved surfaces.

Basic structure of the steel composite panel (SVP)

The steel composite panel (SCP) is based on the aforementioned steel plate (10, 30) but is inherently rigid (and therefore no longer flexible) and comprises at least a first layer, preferably containing iron (the steel plate 10), a thermoplastic second layer (20) bonded to it by force and/or material bonding, and optionally a third layer, also preferably containing iron (the steel plate 30). The layers can be joined by lamination, press-lamination, co-extrusion, bonding with structural adhesives, or by comparable methods. The first layer (10) is preferably made of steel sheet. The second, thermoplastic layer (20) serves in particular as a core to increase flexural stiffness at a low areal weight and as a vibration damper.

In preferred embodiments, the iron-to-thermoplastic layer thickness ratio is 1:2 to 1:4, particularly 1:3. For example, the SVP can have a total thickness of 2.0 mm to 6.0 mm, preferably about 3.0 mm. The first layer (10) can have a thickness of 0.2 mm to 1.5 mm, preferably 0.3 mm to 1.0 mm; corresponding values apply to an optional third iron layer (30). The second thermoplastic layer (20) can have a thickness of 0.8 mm to 4.5 mm, preferably 1.5 mm to 3.5 mm.

The thermoplastic material is preferably polyethylene (PE), in particular LDPE. Alternatively, HDPE, PP, or thermoplastic elastomers are possible. The SVP may additionally contain functional additives (e.g., flame retardants to achieve a defined fire behavior) and/or fillers.

Surface structure, coating and printing

A coating (53) is preferably arranged on at least one outer surface of the steel plate (10). The coating (53) can be designed as a primer, lacquer, protective or functional layer and serves in particular to promote adhesion for the motif printing, to provide abrasion protection and to facilitate cleaning. The thickness of the coating can be, for example, 5 µm to 300 µm, preferably 20 µm to 150 µm.

Alternatively or additionally, the steel plate (10) or SVP has a decorative layer, which is arranged in the surface coating (11), between the first (10) and second layer (20), or within the second layer (20). Alternatively, the second layer (20) is also designed as a decorative layer, for example, using conventional coloring methods.

The motif is preferably applied using multi-stage UV printing, but other suitable printing methods are also possible, such as laser printing, heat transfer printing, screen printing, pad printing, or thermal transfer. UV printing, especially with multi-layered designs, allows for a strong depth effect, which is further enhanced by the relief created through multi-stage pattern printing, or by the depth effect created by a relief structure, through targeted reflection properties of adjacent surface areas.

In a preferred embodiment, different printed layers are combined to create a realistic tile or textured effect, in particular (i) white underprinting in certain areas, (ii) colored motif printing, and (iii) transparent varnish or clear varnish layers. Partial white underprinting and/or varnish build-up can create tactile reliefs that visually replicate 'valleys' and 'mountains' (e.g., grout lines and tile edges). Alternatively or additionally, matte and glossy surface areas can be created by selecting suitable UV varnishes, by partial gloss varnishing, or by different screen rulings. Glossy tile surfaces and matte grout lines are preferred. The above-described process is used analogously for the particularly realistic reproduction of other surfaces or panoramic effects, for example, in creating an optical image of a stone relief, a mosaic, a wooden surface or furniture, library walls, seating areas, and the like.

In further embodiments, the SVP is printable on both sides or has a functional layer on the reverse side (e.g., adhesion promoter for adhesive mounting, sealing layer, acoustic damping). The printing parameters (e.g., lamp power, throughput speed, ink type, droplet size, intermediate drying, overprint sequence) can be set product-specifically to achieve defined scratch resistance, color brilliance, and chemical resistance to common cleaning agents.

According to the invention, the wall functional elements have a weight of at least 300 g, preferably at least 500 g, more preferably at least 1 kg, and even more preferably at least 2 kg, and/or a depth of at least 3 cm, preferably at least 5 cm, more preferably at least 10 cm, and even more preferably at least 20 cm. Alternatively or additionally, the wall functional elements further have a minimum surface area of 20 ^cm² , preferably 30 ^cm² , more preferably 40 ^cm² , and even more preferably 50 ^cm² .

In contrast to conventional whiteboards, which typically have a thin aluminum or steel cover layer with a writing surface (e.g., lacquer or enamel), the steel plate according to the invention is designed as a full-surface, motif-designed, e.g., printed, flexible wall covering or, preferably, as a rigid steel plate (SVP) with increased stiffness and designed for large-area installations. Furthermore, the system is designed for the secure mounting of heavy, freely positionable wall functional elements. Conventional magnetic sheets (e.g., for vehicle lettering) are generally unsuitable for high loads and hygienically robust continuous use and often require adhesives; in contrast, the BFP of the present invention can be designed without an external adhesive layer and can be positioned purely magnetically or by its own adhesion to the steel plate or SVP.

Mounting the steel plate (or SVP) to the wall

The steel plate (or SVP) can be mounted directly onto an existing wall or surface. Depending on the substrate, mounting can be achieved by bonding (e.g., with construction adhesive or structural adhesives), screwing into a substructure, a combination of bonding and mechanical fastening, or clamping/frame systems. Preferably, several SVP modules are butted together or arranged with defined joint widths to cover an entire wall surface. The SVP can be cut to size; for example, panel sizes up to approximately 3050 mm x 1220 mm can be used. The installation can be frameless, with butt joints concealed by profiles, sealants or decorative joints.

In hygienically sensitive areas (e.g., fresh food counters, operating rooms, or laboratories), a surrounding edging in the hygienic profile can be provided, preferably silicone-sealed to reduce the penetration of dirt and moisture. The surface is preferably washable and suitable for common cleaning and disinfecting agents, including UV irradiation in operating rooms, for example. Because installation requires no tile removal, filling, or drying time, renovations can often be carried out with minimal or no downtime.

In a preferred embodiment, the steel plate (or the SVP) and the BFP are essentially or completely the same size, and thus have identical dimensions, at least in terms of length and height.

Magnetically attachable wall decoration and/or wall functional elements

The wall decoration and/or wall functional elements (40) are designed to be reversibly attached to the steel plate (or SVP) without screws, plugs, snap-fit connections, and/or adhesive bonds. For this purpose, each element has at least one magnet (42). The magnetic pull of the magnet (42) is preferably selected to be at least five times the weight of the wall decoration and/or wall functional element (40). This safety factor takes into account dynamic loads (e.g., impacts), manufacturing tolerances, surface coatings, and aging. In preferred embodiments, the magnetic pull is six to fifteen times the weight.

The magnet (42) can be designed as a single piece or in multiple parts. In the case of a multi-part design, the magnetic parts are preferably spaced evenly apart to reduce tilting of the element and to generate a uniform surface pressure. The magnetic parts can be screwed, glued, cast in place, or snapped into receptacles. Additionally, friction-enhancing intermediate layers (e.g., elastomer pads) can be provided to absorb shear forces.

The wall decoration and/or wall functional elements (40) can have a minimum surface area of 15 ^cm² , in particular at least 20 ^cm² . Preferably, the wall decoration and/or wall functional elements (40) are designed as 3D letters (e.g., 3D-printed), logos, shelves, racks, hook modules, poster pockets, product carriers, or TV/monitor cassettes. For heavy wall functional elements, a combination of several magnetic elements and optional mechanical support elements can be provided, the latter preferably also requiring no drilling into the wall (e.g., by means of support on the floor, positive locking against profiles, or in grooves).

According to the invention, the wall decoration and/or wall functional elements (40) therefore have a weight of at least 300 g, preferably at least 500 g, more preferably at least 1 kg, and even more preferably at least 2 kg, and/or a depth of at least 3 cm, preferably at least 5 cm, more preferably at least 10 cm, and even more preferably at least 20 cm. The wall functional elements furthermore, alternatively or additionally, have a minimum surface area of 20 ^cm² , preferably 30 ^cm² , more preferably 40 ^cm² , and even more preferably 50 ^cm² .

Design of magnetic force and load

For example, the following relationship can be used for interpretation: $$\begin{array}{c}\text{F}\_\text{M}>/=\underset{\_}{\text{S}*\text{m}*\text{g}}\\ \mathrm{\mu }\end{array}$$
where F_M is the resulting magnetic tensile force of all magnet parts, m is the mass of the element, g is the acceleration due to gravity, S is a safety factor (S ≥ 5), and µ is the coefficient of static friction. For multi-part magnets, F_M is the sum of the individual tensile forces. For elements with a large lever arm (e.g., shelves), a tilting moment M_K can also be taken into account, whereby the arrangement of the magnet parts is selected to generate a sufficient counter-moment. Preferably, a selection table (e.g., as part of a kit) is provided to the user, which specifies permissible element weights depending on the number of magnet parts, the spacing between the magnet parts, the thickness of the steel plate (or SVP), and the surface coating.

Alternatively or additionally, electromagnetic holders can be provided, which can be activated temporarily to assist with assembly or provide a higher holding force for particularly heavy elements.

The magnet (42) according to the invention, however, is not designed as an industrial magnet. In other words, the magnetic force does not exceed a maximum value of at least 7 times, preferably at least 10 times, more preferably at least 15 times, and even more preferably 100 times the weight of the elements. This has the advantage that, although the element is designed for permanent and secure holding and can withstand additional loads, such as the placement of objects, it is nevertheless a reversible installation that can be removed from the steel plate (or SVP) by a skilled worker, in particular without additional tools, without leaving any residue or causing damage.

Flexible sheet as replaceable magnetic foil

The flexible sheet (BFP, 50) comprises a first layer (51) with or consisting of a ferritic layer and a second layer (52) comprising a polymer, which is bonded to it. Preferably, the BFP (50) does not have an adhesion promoter layer on an outer surface, so that it can be positioned on the steel plate (or SVP) without adhesives. The BFP (50) may have a printed layer (54) applied to the side of the second layer (52) facing away from the ferritic layer (51), which is produced in particular by a multi-stage printing process (e.g., UV printing). Preferably, the BFP (50) is produced in large formats, e.g., with an area of at least 1.0 ^m² , and in particular more than 1.2 ^m² , to allow for a full-surface background change (e.g., seasonal and/or regional). Preferably, the steel plate (or SVP) and BFP (50) are designed to be identical in area or substantially identical according to the invention.

The BFP (50) can be arranged across the entire surface, as a circumferential frieze, or as a focal point on the steel plate (or SVP), namely by arranging the ferritic layer on the steel plate (or SVP) such that the printed second layer is located on the side of the BFP facing away from the SVP. According to the invention, replacing the BFP modifies the overall design without requiring the steel plate (or SVP) to be disassembled or reprinted. This significantly reduces storage requirements and assembly time. In one embodiment, several BFP segments are provided, which are joined together at butt joints with overlapping edges or with magnetically fixed end strips.

System as a kit and logistical aspects

The modular system according to the invention can be provided as a set or kit, comprising in particular: (i) at least one steel plate (or SVP) with a basic motif, (ii) at least one interchangeable BFP (magnetic foil) with a theme-related, in particular seasonal, regional or campaign-related motif, (iii) a plurality of magnetic wall decoration and/or wall functional elements, (iv) optional mounting aids (e.g. positioning templates, spacers), (v) optional profiles and sealants (e.g. hygienic profile, silicone), and (vi) optional design aid for magnetic force/load (e.g. table or calculation instructions). Due to the modular provision, an operator (e.g., an independent branch owner) can carry out redesigns with reduced personnel and time expenditure.

Another aspect of the system according to the invention relates to a surface layer according to the invention and a surface layer arranged thereon, the ferritic first layer of which is magnetically connected to the second layer of the surface layer by means of a force-fit connection. Preferably, a wall decoration or wall functional element is also arranged on the surface layer.

Elevated mounting and temporary applications

As an alternative to wall mounting, the SVP can be set up using a stand. The stand preferably has a recess for the vertical insertion of the SVP. This allows for the creation of mobile backdrops, pop-up stands, dust barriers, trade fair or stage sets, and the like. In another embodiment, the SVP can be integrated into a window cassette or a shop window frame system to combine window displays with real objects (e.g., a photorealistic image with a physical product as a magnetized functional element).

use

The invention further includes a use for a system according to the embodiments described above.

When using BFP and magnetic elements simultaneously, the BFP is preferably positioned on the steel plate (or SVP) first, and then the elements are arranged on the BFP or on the exposed steel plate (or SVP). These steps avoid, in particular, dusty, noisy, and dirty conversion work, and can reduce or completely eliminate downtime.

Industrial applicability

The invention is industrially applicable, particularly for the rapid renovation and variable redesign of communication or wall surfaces in retail, service, and public areas, as well as in trade fair, stage, and set construction. The system enables repeated, reversible reconfiguration of design and function without having to dismantle the base support surface of the steel plate (or SVP).
