Description of the invention

The present invention will be described in more detail below.

The present invention provides in a first embodiment, a vertical wall that allows easy attachment of finishing components that has a layered structure consisting of an ultra-light core such as foam, polystyrene, mineral wool located between 2 layers with properties ferromagnetic paints with a thickness ranging from 0.1 mm to 2 mm where at least one layer with ferromagnetic properties is painted on the outside with a non-slip paint characterized by a succession of layers, namely a layer of polyethylene as a protective layer, an acrylic layer as top layer, polyester as primer layer, chromium as chemical layer and a coating covering the inner face of the layer with ferromagnetic properties.

In a preferred embodiment, the ultra-light core, for example polystyrene or mineral wool, is applied to the two layers with ferromagnetic properties by means of an adhesive layer.

In another embodiment, when the ultra-light core is foam, it is no longer necessary to apply the adhesive.

The walls are characterized by an interlocking or "click" system placed vertically. The vertical interlocking system is not a system that embeds the two walls, fixing them, but it is a system that allows the alignment of the walls in plan but also leaving a space to adjust them vertically.

In one embodiment, the ultra-light core is made of foam, polystyrene and mineral wool.

In a preferred embodiment, the ultra-light core has a thickness of between 30 and 150 mm, preferably between 60-100 mm. The thicknesses were chosen taking into account the lift offered by the thickness of the panel corroborated with the metal structure of resistance. The geometry of the metal structure changes depending on the thickness of the panel, without altering the properties of the wall.

The main criterion for which these materials were chosen (foam, polystyrene and mineral wool) is that between the two layers with ferromagnetic properties a filler is needed - a filler - and when choosing this filler, the main advantage is its weight. Other advantages of these materials are: homogeneity, predictability of their behavior in production, ease of cutting them and so on.

In one embodiment, the layer with ferromagnetic properties is preferably, but not limited to, a sheet of galvanized sheet, having a thickness between 0.1 mm and 2 mm. In a preferred embodiment, the thickness of the galvanized sheet is between 0.1 mm and 0.8 mm, a thickness which can be chosen by the person skilled in the art depending on the desired application. In another preferred embodiment, the galvanized sheet varies between 0.18 mm and 0.4 mm with optimum results / performance results on a 0.25 mm sheet.

RO 134845 Α1 a

The layer with ferromagnetic properties is covered with a special non-slip paint characterized by a succession of layers, namely a layer of polyethylene as a protective layer, an acrylic layer as a top layer, polyester as a primer, chrome as a chemical layer and a coating on the inner face. of the layer with ferromagnetic properties. This special non-slip paint is described in patent application no. EP3429434.

It should be mentioned that when the desired space is built, whenever a turn is made (creating an “L” shaped corner looking at the plane of the structure), that wall will be subjected to a “folding” type processing - that is a incision of the layer with ferromagnetic properties at the top, piercing the ultra-light core but not intersecting the layer with ferromagnetic properties located at the bottom.

This milling will be performed at an angle of 91 degrees, to create a fold at 90 degrees. The layer with the remaining ferromagnetic properties acts as a hinge around which the remaining "wings" of the panel will fold. Folding, an “L” section corner will form that will act as a pillar of the structure (Fig. 12). As in the case of a classic construction, the pillars are placed on the corners giving the strength of a rigid structure, even in the case of unclosed contours. Also, the corners thus obtained are much stronger than those made of 2 pieces, which results in an additional advantage of this modular structure.

The walls are delivered debited from the factory at the required height according to the customer's specifications (generally between 2.2 and 3 meters, the most common being used 2.4-2.5 meters).

The preferred section of the vertical wall is 80 mm. There is the possibility of decreasing this section in some cases up to 30 mm, but also increasing it in certain situations, over 150 mm. The increase or decrease of the preferred section of the wall is determined by several factors. First of all, the plan geometry of the assembly must be considered. The darker it is, the stronger the walls, the better the section of the wall can decrease. The more it is necessary to support heavy bodies on the wall (in the case of applications for showrooms, for example - toilet bowls, wall-hung washbasins, etc.), the thicker the panels must be.

The present invention provides, in another embodiment, a kit for constructing a modular structure that allows easy attachment of finishing components comprising:

- a multitude of plates placed coplanarly interconnected by shape which when assembled together form the basis of the modular structure

- a first system of metal profiles (lower strength structure) to be fixed to the base plate by means of fastening means,

- a plurality of interchangeably placed plates interconnected by shape which when assembled together form a support layer with ferromagnetic properties which are fixed over the base,

- a plurality of vertical walls to be arranged perpendicular to the base of the structure and fixable in the first system of metal profiles (lower strength structure) at their lower part where the vertical walls are provided with a layer with ferromagnetic properties at at least one of the outer surfaces ,

RO 134845 Α1

- a second system of metal profiles (upper strength structure) to be fixed to the top of the vertical walls to ensure the stability and rigidity of the structure,

- at least one magnetic support to be attached over the support layer with ferromagnetic properties and on at least a portion of the surface of the vertical walls where the magnetic support is formed at the bottom towards the support layer with ferromagnetic properties of a magnetic foil and a means of attachment to the opposite side of the support with ferromagnetic properties for attaching said finishing components.

In one embodiment, said first system of metal profiles (lower strength structure) consists of a plurality of interconnectable metal segments having the section of the profile U, and the planar shape of said section being straight and / or alternately the shape of the letter "L", "H" or "T" or composite profiles

In one embodiment, the shape interconnection is of the puzzle type with interlocking system.

In one embodiment, the modular structure building kit comprises a base consisting of the plurality of puzzle-shaped interconnected boards with the interlocking system, preferably marked or labeled with a code.

In one embodiment, the plurality of interchangeably placed plates interconnected by shape that together form the support layer with ferromagnetic properties that are fixed over the base are engraved with codes, ie the position where each plate forming the support layer with properties is indicated ferromagnetic, in plan, according to a coding resulting from the design. The cutting in plan (shape) of the plates that form the layer with ferromagnetic properties is with interlocking system ”, so that its placement cannot be wrong, and in the end, the contour resulting from the joining of several plates is a correct dimensional one. .

In one embodiment, said second system of metal profiles (superior strength structure) consists of a plurality of interconnectable metal segments having the profile section U, and the planar shape of said section being straight and / or alternately shaped the letter 'L', 'H' or 'T' or composite profiles in another embodiment, the means of attaching the magnetic backing is an acrylic adhesive applied to a sponge or vinyl or hot-melt adhesive.

In another embodiment the acrylic adhesive applied to the sponge support has the closed cell sponge.

In another embodiment, the backing layer with ferromagnetic properties is a galvanized sheet.

Hot melt adhesives are adhesives that are solid at room temperature and become viscous when heated to a certain temperature. Bonding is done by pressing and after cooling to room temperature, in a few seconds, a strong, durable bonding is achieved in an extremely short time.

In a further embodiment, the modular structure is provided for the vertical walls or for the finishing components to be installed (eg ceramic tiles, parquet, carpet), with the magnetic support glued directly to the cladding material of the vertical walls with a vinyl or hot-melt adhesive.

RO 134845 Α1

Hot-melt or vinyl adhesives were chosen for cost reasons because acrylic adhesive applied on a sponge support is more expensive and its use on walls of structures that are not subjected to mechanical pressure that occurs on the floor leads to significant cost reductions.

In a preferred embodiment, the attachment means is an acrylic adhesive applied to a sponge support.

If it is desired to apply on a ceramic plate that has a back with irregularities and a high pattern, then it is desirable that the multilayer magnetic support be provided with a sponge adhesive attachment means that will be able to take the pattern of on the back of the ceramic tile, thus increasing the contact force between the ceramic tile and the layer with ferromagnetic properties.

The multilayer magnetic support with acrylic adhesive applied on a sponge support gives the following advantage: when you want to change the ceramic collection / carpet due to wear, damage, delisting from the portfolio, this removal / replacement of finishing components takes place quickly. The attachment to the magnetic support removes the disadvantages of the classic gluing (with adhesive of ceramic tiles / parquet / carpet) whose replacement would have led to the appearance of noise, dust and, in general, discomfort for the space in which it is intended. After detaching the finishing elements together with the magnetic support on the walls / floor, the integrity of the vertical walls / floor is ensured, which can thus be reused in other configurations or for the exposure of other finishing elements.

Another major advantage is that the installation / uninstallation of products using this system takes place at a speed of approx. 10 times higher than in the classic working mode.

The sponge has the role of taking over the unevenness behind the finishing elements, especially in the case of ceramic tiles. Basically, the relief behind the ceramics is "imprinted" in the sponge, and the finish is uniform and leveled in this way. An additional advantage of using a sponge layer is that it minimizes the risk of ceramic tiles breaking. In the absence of the sponge, there is a risk that the ceramic tiles, for example, will break when they are lipid only with magnetic foil because their placement would be only on the “ridges” of the relief on the back.

The preferred composition of the sponge support is "polyolefin" with a density between 50 and 120 kg / m3 but polyethylene or polyurethane variants with the same density are also accepted. If the density of the sponge support is less than 50 kg / m3, then it is very malleable and will settle very easily. If it is denser than 120 kg / m3, then it will be too rigid to penetrate the relief cavities on the back of the ceramic tile and the gluing will be done on the "ridges" of the back of the ceramic tile. In a preferred embodiment, the density is 95 kg / m3 which provides optimal bonding.

It is preferable that the acrylic adhesive applied on the sponge support has the sponge with closed cell and not with open cell. It is preferable that the sponge over which the adhesive is applied has a closed cell for the following reasons:

- compressive strength is superior,

- the "memory" of the support on which the adhesive is applied - the one with the closed cell "recovers", the compression is not a permanent one. If the settlement were permanent, if

EN 134845 Α1 gluing on ceramic tiles, especially for those on the floor, the adhesive applied on the sponge not returning to its original shape, would not fill the gaps on the back of the tiles,

- superior resistance to stress (eg tension / traction) compared to the open cell support sponge.

Next, each component of the modular structure building kit will be described in detail.

The basis of the modular structure

The multitude of coplanarly placed plates interconnected by shape (puzzle type with interlocking system) is assembled to form the basis of the modular structure. These interconnecting boards can be made of any type of suitable material selected, preferably from the range of wood chipboard (water-repellent, MDF, OSB). In a preferred embodiment, the interconnectable plates forming the base of the modular structure are preferably made, but not limited to, of the water-repellent chip. The advantage of using this material is given by the advantageous price, the ease of processing it on machines with high speed numerical control (laser cutting, CNC router cutting, etc.), the versatility in terms of preferred thickness for the application, durability over time. The thickness of the interconnectable boards that form the basis of the modular structure is between 9 and 40 mm, but can vary depending on several factors. The thickness of the plate is determined by a specialist in the field depending on the stress to which the modular structure will be subjected. For example, a vertical wall that due to the geometry of the assembly does not benefit from supports (which does not close in a shape type "L" or "H" or "T"), will require, when pushed, the base of the modular structure. Thus, it will tend to rise from the floor, considering an inconvenient moment around the support (ie around the modular structure attached to the base of the structure, the structure in which the panel is mounted). The smaller the thickness of the interconnectable plates that form the base of the structure, the greater the bending moment. In such situations, rigid interconnectable boards will be dimensioned, with a greater thickness, preferably 30-40mm and maybe even with an increased mechanical strength (OSB).

The base of the modular structure is designed as a puzzle, the multitude of interconnectable boards being cut on an interlocking system, ie the boards can only be mounted in certain positions, the positions that are for which they were intended. This interlocking system and puzzle structure give one of the main advantages of the product by saving assembly time compared to classic systems. The multitude of interconnectable plates that together form the base of the structure, preferably made of chipboard, but without being limited to it, are placed on the floor according to the plan, are coupled, in interlocking system. Thus, the base of the modular structure is made.

To facilitate the assembly, on each interconnectable plate by shape, is marked a number, engraved the space where the metal resistance profile will be mounted and possibly the number of the corresponding vertical wall and its delimitation (Fig 1, Fig 2).

Thus, the base of the modular structure is inscribed with assembly instructions in order to be able to carry out the assembly easily and quickly.

Optionally, the construction kit can contain written instructions on paper for easy mounting of the modular structure.

RO 134845 Α1

A first system of metal profiles (lower resistance structure) consisting of a multitude of profiles interconnectable metal segments of type U, L, T, H or composite profiles, depending on the necessary geometry that will describe the contour of the walls and will be mounted on the base structure in the appropriate positions. The “U”, “L”, “T” and Ή ”type profiles or composite profiles play a structural role, supporting at the bottom the vertical walls of the magnetic modular structure. The metal profiles arranged on the basis of the structure form a first system of metal profiles (lower resistance structure) which consists of a multitude of interconnectable segments having the profile section U and the planar shape of that section is straight and / or alternately L-shaped. , Η, T or composite profiles.

The metal profiles type “U”, “L”, “T” and Ή ”have the inner section equal to the dimension of the vertical wall section to which 1-2 mm is added. The preferred thickness of the material from which the “U”, “L”, “T” and Ή ”profiles are made is between about 1 and about 5 mm. In a preferred embodiment, the thickness of the metal profile material is between about 1.5 mm and about 2 mm.

- the strength given to the lower strength structure by the use of this thickness is sufficient,

- by using this thickness of the metal profiles of the resistance structure, the finishing plate (for example plasterboard or MDF, but not limited to them) will "pass" over the metal structure when it is mounted elegantly finishing the wall. This is because we must not forget that on the back of the plate is applied a magnetic foil accompanied by a suitable means of attachment (preferably an acrylic adhesive applied on a sponge or vinyl or hot melt type adhesive), layers that accumulate 1.5 -2 mm.

In a preferred embodiment, each profile is marked or labeled with a code indicating the mounting position, being already cut to length (Fig. 1 and Fig. 2).

In another embodiment, the profiles can also be cut on site / on site.

if marked, the profiles are placed on the corresponding positions marked on the basis of the modular structure.

Support layer with ferromagnetic properties (placed over the base of the structure)

The support layer with ferromagnetic properties is formed by assembling a multitude of interconnectable puzzle-shaped plates with interlocking system. These interconnecting plates that form the support layer with ferromagnetic properties can be cut and marked with a code so that they can be mounted in the appropriate places based on the modular structure.

In one embodiment, the layer with ferromagnetic properties is preferably, but not limited to, a sheet of galvanized sheet, having a thickness between 0.1 mm and 2 mm. In a preferred embodiment, the thickness of the galvanized sheet is between 0.1 mm and 0.8 mm, the thickness of which may be chosen by the person skilled in the art depending on the desired application. In another preferred embodiment, the thin sheet of galvanized sheet varies between 0.18 mm and 0.4 mm with optimal results / performance results on a 0.25 mm sheet.

The layer with ferromagnetic properties can be covered with a special non-slip paint characterized by a succession of layers, namely a layer of polyethylene as a protective layer, an acrylic layer as a top layer, polyester as a primer layer, chrome as a layer

RO 134845 Α1 chemical and a coating covering the inner face of the layer with ferromagnetic properties. This special non-slip paint is described in patent application no. EP3429434.

In another embodiment, the layer with ferromagnetic properties can be cased over the base of the modular structure, thus the base and the ferromagnetic layer becoming a single piece. Vertical walls of the modular structure

Vertical wall that allows easy attachment of finishing components that has a layered structure consisting of an ultra-light core such as foam, polystyrene, mineral wool located between 2 layers with ferromagnetic properties with a thickness ranging from 0.1 mm to 2 mm, where at least one layer with ferromagnetic properties is painted on the outside with a non-slip paint characterized by a succession of layers, namely a layer of polyethylene as a protective layer, an acrylic layer as a top layer, polyester as a primer, chrome as a layer chemical and a coating covering the inner face of the layer with ferromagnetic properties.

The walls are characterized by an interlocking system "interlocking" or "click" placed vertically. The vertical interlocking system is not a system that embeds the two walls, fixing them but it is a system that allows the alignment of the panels in plan but also leaving a space to adjust them vertically. The arrangement of the vertical walls next to each other together with the interlocking or "click" system creates a structure with a common body.

A second system of metal profiles (superior strength structure) consisting of a multitude of profiles interconnectable metal segments type U, L, T, H or composite profiles, depending on the required geometry will describe the outer perimeter of the upper side of the vertical walls walls and will be mounted on top of them (upper strength structure). These “U”, “L”, “T”, Ή ”or composite profiles are mounted at the top of the vertical walls which are also“ glued ”to the vertical wall by inserting suitable fastening means, being preferred , but not limited to, pop-rivets. They have the same characteristics as those that form the first system of metal profiles (lower strength structure) for the reasons listed above.

It is important to note that the metal profiles that form the first system of metal profiles (lower strength structure) at the base of the walls are offset from the metal profiles that form the second profile system (upper strength structure), so that in -a vertical section, their joints to be staggered or "woven" to give additional strength to the modular structure.

Multilayer magnetic support

The multilayer magnetic support consists of a magnetic foil (through which it can be fixed to the layer with ferromagnetic properties) and a suitable means of attachment (eg acrylic adhesive applied on a sponge support or vinyl or hot melt adhesive) on which can easily attach the desired finishing components (eg ceramic, ceramic wall and floor tiles, marble, granite, parquet, linoleum, carpet and other materials suitable for covering surfaces, etc.).

Preferably, the magnetic foil has a thickness of between 0.2 and 3 mm, preferably 0.4 mm for an optimal contact force, but its thickness can be chosen by the person skilled in the art, depending on the weight of the plate to be exposed. In a preferred embodiment,

RO 134845 Α1 the attachment means of acrylic adhesive type applied on a sponge support has a thickness between 0.2 and 5 mm, preferably 1 mm which has an optimal level of taking over the unevenness of the element that is applied on the multilayer magnetic support.

If it is desired to attach to the multilayer magnetic support of a ceramic plate that has an irregular back and a high pattern, it is preferable to use an acrylic adhesive applied on a sponge support (especially if the ceramic plate is will mount on the floor where it is subjected to higher pressure) which will be able to adhere to the embossed pattern on the back of the ceramic tile, thus increasing the contact force between the ceramic tile and the layer with ferromagnetic properties. The role of the acrylic adhesive applied on the sponge support is to take over the unevenness behind the finishing elements, especially in the case of ceramic tiles. Basically, the relief behind the ceramics is “imprinted” in the acrylic adhesive applied on a sponge support, and the finishing element is uniformed and leveled in this way. An additional advantage of using acrylic adhesive applied on a sponge is that the ceramic tiles do not break. In the absence of acrylic adhesive applied on a sponge, there is a risk that if the pressure is very high and the traffic is heavy, the ceramic tiles will break because their placement would be only on the "ridges" of the relief on the back of the ceramic tile. The multilayer magnetic support with acrylic adhesive applied on a sponge support gives the following advantage: when you want to change the ceramic / carpet collection due to wear, damage, delisting from the portfolio, this change is done quickly, the products being easily detached. The use of magnetic foil removes the disadvantages of the classic gluing of finishing elements (ceramic tiles, parquet, carpet) whose replacement would have led to the appearance of noise, dust and, in general, discomfort for the space in which it is intended.

Another major advantage is that the installation / uninstallation of the finishing elements takes place with a speed of approx. 10 times higher than in the classic working mode.

If you want to use a ceramic tile that has a back with irregularities and a high pattern on one of the vertical walls where it is not subjected to a pressure as high as that of a tile placed on the floor, you can use adhesives vinyl or hot melt that ensures the stability of the ceramic tile at the same time at a low cost.

In case of using the acrylic adhesive applied on a sponge support that has a protective layer called “liner”, the finishing components (ceramic, parquet, linoleum, etc.) are placed on the acrylic adhesive applied on the sponge support after removing the liner and fixed in desired position by pressing.

The present invention provides, in a second embodiment, a modular structure comprising:

- a base of the modular structure consisting of a plurality of plates placed coplanarly interconnected by shape,

- a first system of metal profiles (lower strength structure) fixed to the base by means of fastening means,

- a support layer with ferromagnetic properties arranged above the base and consisting of a plurality of plates interconnected by shape,

- a plurality of vertical walls arranged perpendicular to the base and fixed in the first system of metal profiles at their lower part io

EN 134845 cu1 where the vertical walls are provided with a layer with ferromagnetic properties on at least one of the outer surfaces,

- a second system of metal profiles (upper strength structure) fixed to the top of the vertical walls to ensure the stability and rigidity of the structure,

- a multilayer magnetic support arranged over the support layer with ferromagnetic properties and on at least a portion of the surface of the vertical walls where the multilayer magnetic support is formed at the bottom towards the support layer with ferromagnetic properties by a magnetic foil and an attachment means corresponding to the top.

In a preferred embodiment, the shape interconnection is of the puzzle type with interlocking system.

In one embodiment, said first system of metal profiles (lower strength structure) is composed of a plurality of interconnected metal segments having the section of the profile U, and the planar shape of said section being straight and / or alternately the shape of the letter "L", "H" or "T" or composite profiles.

In one embodiment, said second system of metal profiles (superior strength structure) consists of a plurality of interconnected metal segments having the profile section U, and the planar shape of said section being straight and / or alternately shaped the letter "L", "H" or "T" or compound profiles.

The appropriate attachment means can be an acrylic adhesive applied on a sponge support or a vinyl or hot melt type adhesive.

In a further embodiment, the modular structure has, for the vertical walls or for the finishing components to be installed (eg ceramic tiles, parquet, carpet), the magnetic foil glued directly to the cladding material of the vertical walls with a vinyl or hot-melt adhesive.

Next, each component of the magnetic modular structure will be described in detail.

The basis of the modular structure

The base of the modular structure is obtained by interconnecting the multitude of boards that can be made of any type of suitable material selected from the range of chipboard (water-repellent, MDF, OSB). In a preferred embodiment, the base of the modular structure is preferably made, but not limited to, of water-repellent pallet. The advantage of using this material is given by the advantageous price, the ease of processing it on machines with high speed numerical control (laser cutting, CNC router cutting, etc.), versatility in terms of preferred thickness for the application, durability over time. The thickness of the motherboard or fingerprint is between 9 and 40 mm, but can vary depending on several factors. The thickness of the plate is determined by a specialist in the field depending on the request to which the structure is exposed. For example, a vertical wall that due to the geometry of the assembly does not benefit from supports (which does not close in a shape type "L" or "H" or "T"), will require, when pushed, the basic structure and default motherboard. Thus, it will tend to rise from the floor, considering an inconvenient moment around the support (ie around the structure attached to the plate, the structure in which the panel is mounted). The smaller the thickness of the plate, the greater the bending moment. In such

RO 134845 Α1 situations will be dimensioned a rigid motherboard, with a greater thickness, preferably 3040mm and maybe even with an increased mechanical strength (OSB)

The base of the modular structure is thought of as a puzzle, the interconnectable plates that form the base being cut on an interlocking system, ie the plates can only be mounted in certain positions, the positions that are for which they were intended. This interlocking system and puzzle structure give one of the main advantages of the product by saving assembly time compared to classic systems. The interconnected plates that are assembled form the basis of the modular structure which are preferably, but not limited to, of water-repellent chipboard, are placed on the floor according to the plan, are coupled, in the interlocking system. Thus, the basis of the modular structure is realized.

To facilitate the assembly, on each piece of the base plate or imprint is engraved a number engraved respectively the space where the resistance profile will be mounted and possibly the number of the vertical wall and its delimitation (Fig 1, Fig 2).

Thus, the base of the modular structure is noted in order to be able to carry out the assembly easily and quickly.

A first system of metal profiles (lower resistance structure) consisting of a multitude of profiles interconnectable metal segments of type U, L, T, H or composite profiles, depending on the necessary geometry that will describe the contour of the walls and will be mounted on the base structure in the appropriate positions. The “U”, “L”, “T” and “H” type profiles or composite profiles play a structural role, supporting at the bottom the vertical walls of the magnetic modular structure. The metal profiles arranged on the basis of the structure form a first system of metal profiles (lower resistance structure) which consists of a multitude of interconnectable segments having the section of the U profile and the planar shape of that section is straight and / or alternately L-shaped. , Η, T or composite profiles. The characteristics of the metal profiles are described above herein, in a preferred embodiment, each profile has marked or labeled a code indicating the mounting position, being already cut to length (Fig. 1 and Fig. 2).

In another embodiment, the profiles can also be cut on site / on site.

if marked, the profiles are placed on the corresponding positions marked on the basis of the modular structure.

Support layer with ferromagnetic properties (placed over the base of the structure)

The support layer with ferromagnetic properties is formed by assembling a multitude of interconnectable puzzle-shaped plates with interlocking system. These interconnecting plates that form the support layer with ferromagnetic properties can be cut and marked with a code so that they can be mounted in the appropriate places based on the modular structure.

In one embodiment, the layer with ferromagnetic properties is preferably, but not limited to, a sheet of galvanized sheet, having a thickness between 0.1 mm and 2 mm. In a preferred embodiment, the thickness of the galvanized sheet is between 0.1 mm and 0.8 mm, the thickness of which may be chosen by the person skilled in the art depending on the desired application. In another preferred embodiment, the thin sheet of galvanized sheet varies between 0.18 mm and 0.4 mm with optimal results / performance results on a 0.25 mm sheet.

RO 134845 Α1

The layer with ferromagnetic properties is covered with a special non-slip paint characterized by a succession of layers, namely a layer of polyethylene as a protective layer, an acrylic layer as a top layer, polyester as a primer, chrome as a chemical layer and a coating on the inner face. of the layer with ferromagnetic properties: this special non-slip paint is described in patent application no. EP3429434.

Vertical walls of the modular structure

Vertical wall that allows easy attachment of finishing components that has a layered structure consisting of an ultra-light core such as foam, polystyrene, mineral wool located between 2 layers with ferromagnetic properties with a thickness ranging from 0.1 mm to 2 mm where at least one layer with ferromagnetic properties is painted on the outside with a non-slip paint characterized by a succession of layers, namely a layer of polyethylene as a protective layer, an acrylic layer as a top layer, polyester as a primer, chrome as a chemical layer and a coating covering the inner face of the layer with ferromagnetic properties.

The walls are characterized by an interlocking system or “click” placed vertically. The vertical interlocking system is not a system that embeds the two walls, fixing them but it is a system that allows the alignment of the panels in plan but also leaving a space to adjust them vertically.

The arrangement of the vertical walls next to each other together with the interlocking or "click" system creates a structure with a common body.

The vertical wall is inserted on the “channel” formed by the profiles “U”, “L”, “T”, Ή ”and in these profiles are drilled holes that pierce the layer with ferromagnetic properties of the wall (both on the front and on the back) and The "gluing" of the vertical walls to the profiles is done by inserting suitable fastening means, being preferred, but not limited to, rivets that open behind the layer with ferromagnetic properties (sheet) of the vertical wall, in the ultra-light layer, preventing him from leaving.

A second system of metal profiles (superior strength structure) consisting of a multitude of profiles interconnectable metal segments type U, L, T, H or composite profiles, depending on the required geometry will describe the outer perimeter of the upper side of the vertical walls walls and will be mounted on top of them (upper strength structure). These “U”, “L”, “T”, “H” type profiles or composite profiles are mounted at the top of the vertical walls which are also “glued” to the vertical wall by inserting suitable fastening means, being preferred , but not limited to, pop-rivets. They have the same characteristics as those that form the first system of metal profiles (lower strength structure) for the reasons listed above.

Here it is important to take into account the following aspect: the profiles at the bottom are offset from the profiles at the top, so that their joints are "woven" to give additional strength to the magnetic modular structure thus obtained.

Multilayer magnetic support

The multilayer magnetic support consists of a magnetic foil (through which it can be fixed to the layer with ferromagnetic properties) and a suitable means of attachment (eg acrylic adhesive applied on a sponge support or vinyl or hot melt adhesive) on which can easily attach the desired finishing components (eg ceramic, tiles,

RO 134845 Α1 marble, granite, parquet, linoleum, carpet and other materials suitable for covering surfaces, etc.).

Preferably, the magnetic foil has a thickness of between 0.2 and 3 mm, preferably 0.4 mm for an optimal contact force, but its thickness can be chosen by the person skilled in the art, depending on the weight of the plate to be exposed. In a preferred embodiment, the sponge adhesive type attachment means has a thickness between 0.2 and 5 mm, preferably 1 mm which has an optimal level of taking up the unevenness of the element which is applied on the multilayer magnetic support.

If it is desired to attach the multilayer magnetic support on ceramic tiles that has an irregular back and a high pattern, it is preferable to use an acrylic adhesive applied on a sponge support (especially if the ceramic plate will be mounted on the floor where it is subjected to higher pressure) which will be able to adhere to the embossed pattern on the back of the ceramic tile, thus increasing the force of contact between the ceramic tile and the layer with ferromagnetic properties. The role of the acrylic adhesive applied on the sponge support is to take over the unevenness behind the finishing elements, especially in the case of ceramic tiles. Basically, the relief behind the ceramics is “imprinted” in the acrylic adhesive applied on a sponge support, and the finishing element is uniformized and leveled in this way. An additional advantage of using acrylic adhesive applied on a sponge is that the ceramic tiles do not break. In the absence of acrylic adhesive applied on a sponge, there is a risk that if the pressure is very high and the traffic is heavy, the ceramic tiles will break because their placement would be only on the "ridges" of the relief on the back of the ceramic tile. The multilayer magnetic support with acrylic adhesive applied on a sponge support gives the following advantage: when you want to change the ceramic / carpet collection due to wear, damage, delisting from the portfolio, this change is done quickly, the products being easily detached. The use of magnetic foil removes the disadvantages of the classic gluing of finishing elements (ceramic tiles, parquet, carpet) whose replacement would have led to the appearance of noise, dust and, in general, discomfort for the space in which it is intended.

Another major advantage is that the installation / uninstallation of the finishing elements takes place with a speed of approx. 10 times higher than in the classic working mode.

If you want to use a ceramic tile that has a back with irregularities and a high pattern on one of the vertical walls where it is not subjected to a pressure as high as that of a tile placed on the floor, you can use adhesives vinyl or hot melt that ensures the stability of the ceramic tile at the same time at a low cost.

when using the acrylic adhesive applied on a sponge support that has a protective layer called "liner", the finishing components (ceramic, parquet, linoleum, etc.) are placed on the acrylic adhesive applied on the sponge support after removing the liner and fixed in position desired by pressing.

The modular structure thus obtained can be decorated with the desired finishing components. Thus, if on the bottom (on the floor) you want a carpet, parquet, ceramic finish that has a magnetic support for easy replacement over the base of the structure, place the layer with laser-cut ferromagnetic properties also in interlocking system (interlocking) and marked with a code.

In a preferred embodiment, over the layer with ferromagnetic properties which is preferable, but not limited to, the galvanized sheet painted with the non-slip paint described in patent application no. EP3429434, the magnetic support is placed.

On the multilayer magnetic support are placed the desired finishing components (eg ceramics, parquet, linoleum, carpet and other materials suitable for covering surfaces).

If you want to use a ceramic tile that has a back with irregularities and a high pattern, it is preferable to use a sponge adhesive for the reasons mentioned above. The sponge has the role of taking over the unevenness on the back of the finishing plates, especially in the case of ceramic tiles.

If you want to use a ceramic tile that has a back with irregularities and a high pattern on one of the vertical walls where it is not subjected to a pressure as high as that of a tile placed on the floor, you can use adhesives vinyl or hot melt that ensures the stability of the ceramic tile at the same time at a low cost.

Therefore, the support layer with ferromagnetic properties is placed, which is preferable, but not limited to, the galvanized sheet based on the modular structure which is preferably made of, but not limited to, water-repellent, and the sandwich composed of magnetic foil and the appropriate means of attachment selected from the acrylic adhesive applied on a sponge support or vinyl or hot melt type adhesives are placed over the support with ferromagnetic properties.

when using the acrylic adhesive applied on a sponge support that has a protective layer called "liner" the finish (ceramic, parquet, linoleum, etc.) is placed on the acrylic adhesive applied on the sponge support after removing the liner and fixed in the desired position by pressing.

After the floor finish is applied, the wall finish begins. There are many variants available here, from gypsum board to MDF with or without interlocking system, up to paneling, ceramics, wallpaper, prince, etc.

The finish will also be magnetically attached to the vertical walls. Thus, on the back of the finishing materials will be glued longitudinally strips of magnetic foil, similar to the one used for the floor. The magnetic foil can be glued using acrylic adhesive applied on a sponge support or vinyl or hot melt type adhesives.

In a preferred embodiment, the vertical walls will be finished with MDF which has an interlocking system (which uses Unilin's ClicWall technology) which once joined has no joints and can be painted with washable paint which is very advantageous in terms of realization time. Or you can use the same product, but in the melamine or directly printed version. Other suitable materials can also be used, such as MDF or plasterboard, which must be putty and then painted, which slightly increases the execution time.

The modular structure of the present invention can be made in a plurality of interchangeable configurations according to Fig. 12, using the same material, which is one of the main advantages of the present application.

Additionally, the invention also provides a method of assembling this magnetic modular structure. This method comprises the following steps:

- providing a base consisting of a plurality of plates interconnected by shape,
