Description

[0001] Pre-fabrication and installation of coverage of an inner room surface

[0002] TECHNICAL FIELD

[0003] The invention relates to a system and method for pre-fabrication of plates / boards / tiles and installing the plates for covering at least a part of an inner surface of a room, which surface is at least a part of the inner floor and / or the inner wall and / or the inner roof or ceiling and / or an alcove and / or any frame of an opening and / or recess of a door and / or a window etc. in the room.

[0004] BACKGROUND ART

[0005] There are a lot of known ways of covering at least parts of an inner floor, one or more inner walls and / or inner roofs or ceilings of a room with a desired surface coverage. The room could be a so-called wet room, such as a bathroom, or any other room in a house / residence.

[0006] One common known way of laying out coverage on a surface, e.g. a room floor, is to adapt the underlay "in-situ", such as the floor in a bathroom by first cleaning the floor and then apply different materials, often flowable putty that is poured out onto the floor. A similar method is used for walls and / or ceilings but then the putty or plaster is more viscous or thicker to not flow down when put on walls and / or ceilings. Then, a case putty is performed by use of a screed to form the floor putty into correct shape and desired sloping manually to fulfil current building regulations and adapting the solidifying putty in relation to any present water in- and outlets, drainage in the room and adjusting levels of the floor in regard of adjacent spaces or rooms. To even out the surfaces of walls and / or ceilings, both in rooms of new buildings and old ones when renovating after having removed the old wall and / or ceiling coverage in an existing room, such as stone tiles or the like, before putting on any wall and / or ceiling coverage and any new such wall / ceiling coverage, such as stone tiles (again) or plaster boards or the like, the putty or plaster is applied onto the walls and / or ceilings and levelled out manually by using a skimming or plastering spatula when applying and smoothing putty or plaster on walls and / or ceilings, ensuring an even and smooth finish of the associated inner room surfaces.

[0007] Different coverage materials are used, e.g. plastic mats laid onto the floor by gluing onto the putty, plates or boards of wood and / or wood chips / flakes / particles are laid directly on the putty or on scantling laid on the putty or clinker or ceramic / stone tiles are laid onto tile adhesive put on the putty.

[0008] Moreover, nowadays, in wet or sanitary rooms, water proofing layering are provided onto the floor and walls before any tiles or plates or boards are laid, as tiles or plates or boards and grout alone aren't fully waterproof, to fulfil safe wet room demands by following a series of steps and specialized products, typically found in wet room tanking kits, which water proof layering is commonly done on-site in a cumbersome and time demanding way as it demands cleaning, proper levelling of floors and walls, and waiting time for different coatings to dry before the next step is performed, such as allowing primer to dry before putting on a coat of liquid membrane (often a flexible, polymer-based compound that dries into a rubbery layer) using a brush or roller etc.

[0009] Such known methods incur a high physical stress / strain on the operator / -s performing the work manually. This prior art way of working requires long experience and much training to be performed correctly and satisfactorily meaning that even experienced and talented operators are not able to make two identical or at least similar floors and / or walls and / or ceilings exactly the same as the work is done using feeling and experience. The final result is also only possible to check after the work is done and the putty has solidified. It means that delivering the same result / quality each time is difficult as the final result depends on the skills and handicraft of the operators and any corrections of wrongly sloping surfaces are very difficult to perform without having to hewn the floor and redo the puttying and lay out of surface coverage again. The work environment is tough and a heavy burden for the workers as several tons of putty mixed with water are carried daily wearing out the operators meaning that many of them are not able to work until they reach retirement, at least not full time. Any cutting and / or hole making in plates to adapt the plates to a wall and / or ceiling on site is also cumbersome and dusty, in particular if plaster boards are used incurring bad air and difficulty breathing. In many cases, the walls and / or ceilings must be grinded or sanded by hand after the putty or plaster on these surfaces has solidified to further even out or smoothen these wall and / or ceiling surfaces of the room before putting on the finishing coverage, such as wall paper or the like, incurring more dust and effort, in particular if the worker must wear a protective breathing mask, and too much dust must also be removed after grinding and before making the final finishing of the room surface coverage. Many operators also get occupational injuries that make them unable to work from time to time.

[0010] SUMMARY OF THE INVENTION

[0011] It is an object of the present disclosure to mitigate, alleviate or eliminate one or more of the above-identified deficiencies and disadvantages in the prior art and solve at least the above- mentioned problem.

[0012] One object of the present invention is to provide a system and method for coverage of at least a part of an inner surface of a room, preferably a wall and / or ceiling and / or corners in a room by means of a plurality of pre-fabricated and installed plates or boards or tiles that solve or at least reduce or diminish the above problems.

[0013] According to a first aspect there is provided a system for coverage of at least a part of an exposed inner surface of a room by means of a plurality of pre-fabricated cover plates, each plate having a back and a front, the system comprising laid out points of reference on the exposed inner room surface, a 3D scanner to scan the part of the inner room surface vertically and horizontally and the points of reference into a plurality of points of measuring to enable creating a digital 3D representation of the part of the exposed inner room surface, a CAD / CAM system configured to receive the points of measuring from the 3D scanner and to create the digital 3D representation of the part of the exposed inner room surface based on the points of measuring and to transform the digital 3D representation into a suitable number of individual digital plates with identification and dimensions and a CAM controlling manufacturing workflow to manufacture each individual plate accordingly, at least one CAD / CAM controlled machine configured to receive the CAM controlling manufacturing workflow and to physically manufacture the plates individually accordingly, and an installation of each individually prefabricated plate in the room according to the predefined digital 3D representation, c h a r a c t e r i z e d in that the points of measuring from the 3D scanner comprises existing angles between adjoining surfaces of the exposed inner room surface and any unevenness on the exposed inner room surface before installing any board on and / or over the exposed inner room surface, that the CAD / CAM system is configured to use the points of measuring representing the existing angles between adjoining surfaces of the exposed inner room surface and any unevenness on the exposed inner room surface to transform the digital 3D representation into a CAM controlling manufacturing workflow to manufacture the back of each individual plate accordingly to fill out or fit against and / or into any exposed unevenness of the associated inner room surface to provide a flat and / or smooth inner surface of the inner room by means of the front of each plate after covering the associated exposed inner room surface, and that the CAM controlling manufacturing workflow is adapted to control the at least one CAD / CAM controlled machine when forming or machining each plate individually on its back to pre-form the back of each plate to fit against the exposed surface of the inner room surface onto which it is to be put with its back such that the front of each plate forms a flat and / or smooth and / or straight associated inner room surface and a plane extending at an angle between each adjoining front of any other plate on the associated inner room surface being close to perpendicular or perpendicular after the exposed inner room surface has been wholly covered by the pre-formed plates.

[0014] This enables installation of preformed plates or boards or tiles that form a 3D puzzle both horizontally and vertically fulfilling levelling out unevenness of inner room surfaces while creating correct inclination and flat / smooth / even / straight inner surfaces and correct angles between adjoining plates covering the inner room surface on any associated part or surface where plates and / or the walls and / or ceilings and / or openings of windows and / or doorways and / or other appliances to be accessible meet or join after coverage to a finished room surface to secure easier surface finishing, such as paperhanging and assembly of window ledges, skirting boards / baseboards and door molding etc.

[0015] According to some embodiments, the sides and / or edges of one or more of the plates may be manufactured to have an angle to one or more of the back, front, and sides / edges of the same plate which is not perpendicular. Especially the plates intended to be mounted on the wall, and especially on the sides / edges which will connect the wall plates to the floor. This allows the plates mounted on the wall to fit the side(s) and / or edge(s) to a slope or gradient or angle in the floor leading towards a drain in the floor. This makes it easier to install wall plates on sloping floors which are common in wet rooms. The manufactured sides and / or edges of the plates might by way of example be manufactured to have a declining slope or angle from the back to the front of the plate when the manufactured side of the plate faces toward and / or abut the floor. According to some embodiments, the sides and / or edges might also be manufactured to have a slope or angle declining or inclining in a plane parallel to the front of the plate. The side of the plate may be manufactured to have a slope or angle which is both declining from the back to the front of the plate when the manufactured side of the plate faces toward the floor and a slope or angle inclining or declining in a plane parallel to the front of the plate, e.g., along the full width or along only a part of the width of the plate. Even though a floor may have a slope towards a drain at or in or on a certain or smaller part of the floor, not necessarily over the whole floor, the vertical front(s) of the plate(s) on the wall and the upper front and exposed surface(s) of the plate(s) on the floor may still be considered to extend and / or adjoin at angles which are close to perpendicular when mounted in the wet room since the / those slope(s) of the floor may extend at / with very small angle(s). Even though a floor may have at least partly a slope, e.g., be sloping in a certain smaller or restricted area but not sloping over the whole floor, such as towards and close to or in connection with a drain, the vertical front(s) of the plate(s) on the wall and the upper and front and exposed surface(s) of the plate(s) on the floor further away from any drain and having no slope as not being part of the sloping towards the drain at or in or on another part of the floor may still extend at angles relative each other being close to perpendicular or perpendicular as the upper / top / front and exposed surface(s) of the floor plate(s) with no sloping in the room extend(s) in parallel with the horizontal plane when finally mounted in the wet room and the front surface(s) of the wall plate(s) when finally mounted in the wet room extend(s) in parallel with the vertical plane. The walls and the floor of the wet room are straightened up by the plate(s) being trued up compared to the rough and non-covered wall and floor surfaces while still enabling having one or some parts of the floor with slope towards a drain if desired or applicable, such as along a whole wall if an elongated drain is existing or along only a part of a wall, such as in a shower corner.

[0016] According to some embodiments, the plates may be premanufactured by the system to have machined markings on the back of the plates configured to indicate where to apply a glue and to receive the glue prior to mounting the plates on the wall of a room.

[0017] According to some embodiments, the plates may be premanufactured by the system to have glue markings which comprise a glue covered by a cover layer, wherein the cover layer is configured to be removed prior to mounting the plate on the inner room surface and wherein the glue marking is configured to adhere to the inner surfaces of the room when the plate is mounted to the inner surface of the room.

[0018] According to some embodiments, the plates may be premanufactured by the system so that the machined markings and the glue markings define an alternating pattern of parallel stripes on the back of the plates. The stripes of glue markings and the stripes of machined markings might have the same width or have different widths such as the stripes of glue marking being thinner than the machined markings. The stripes may extend across the entire back of a plate or across a portion of the back of a plate.

[0019] According to some embodiments, the plates may be premanufactured by the system so that the machined markings and the glue markings define an alternating pattern of parallel stripes and / or dots and / or dents evenly distributed on the back of the plates. The stripes and / or dots and / or dents of glue markings and the stripes and / or dots and / or dents of machined markings might have the same width and / or shape and / or depths or have different widths and / or shapes and / or depths such as the stripes of glue marking being thinner than the machined markings and / or the dots and / or dents being less wide and / or deep than the machined markings. The stripes may extend across the entire back of each plate or across a portion of the back of each plate. The dots and / or dents may be evenly distributed as fewer but larger dots and / or dents or be distributed as more but smaller dots and / or dents across the entire back of each plate.

[0020] According to some embodiments, the plates may be premanufactured by the system to have machined markings on the back of the plates configured to indicate where to apply a glue and to receive the glue prior to mounting the plates on the wall of the wet room either already at / in the factory before being transported to the site or room for instalment and / or in the room or on site just before the plates are installed on the associated wall surface.

[0021] According to some embodiments, the plates may be premanufactured by the system to have machined markings on the back of the plates in / on which markings glue is applied and received and covered by a removable layer, such as release or backing liner or paper, at / in the factory prior to being transported to the site or room where to mount the plates on the wall. According to some embodiments, the plates may be premanufactured by the system to have machined markings on the back of the plates in / on which markings glue is a pp lied / fi lied and received and covered by a removable layer, such as release or backing liner or paper, at / in the factory prior to being transported to the on-site or room where to mount the plates on the wall and to have other machined markings on the back of the plates not being filled with glue in the factory before being transported. According to some embodiments, those other or further markings not yet filled with glue are intended to be filled with or receive glue just before installing the plates on the wall and the cover layer or release or backing liner over the already glue filled markings are removed or peeled off on-site also just before installing the plates on the wall. This simplifies instalment and more clearly shows the installer where to put glue on the back of the plate and in correct pattern and in what amount before installing the back of the plate to the wall on the inside of the room. It reduces needing two different glues for use and be carried around on-site and also reduces the amount of fumes from glue on-site.

[0022] According to some embodiments, in the system, the CAD / CAM workflow is adapted to control the at least on CAD / CAM controlled machine when forming or machining each plate, to machine or form at least one or more of the plates individually so that at least a first side of the plate is machined or formed to have a slope running from one or more of the back to the front of the plate and / or from a third side to a fourth side of the plate.

[0023] According to some embodiments, the slope or angle of the first side is formed or machined only on plates configured for abutting the floor and / or corner(s) and / or ceiling and wherein these plates are configured to abut the adjoining plate(s) with their first side and wherein the slope or angle of the first side is configured to match a gradient of the adjoining plate(s), such as a gradient of the floor declining towards a drain or gradient of a ceiling extending towards a ridge or top of a ceiling or roof.

[0024] According to some embodiments, one or more of the plates are prefabricated to comprise machined markings on the back and wherein the machined markings are configured to indicate where to apply a glue and to receive the glue prior to mounting the plate on the wall of the inner room surface and wherein the glue received by the premachined markings is configured to adhere to the inner room surface and the plate when the plate is mounted to the inner room surface. According to some embodiments, one or more of the plates are prefabricated to comprise a glue marking on the back which comprises a glue covered by a cover layer, wherein the cover layer is configured to be removed prior to mounting the plate on the inner room surface and wherein the glue of the glue marking is configured to adhere to the inner room surface and to the plate when the plate is mounted to the inner room surface.

[0025] According to some embodiments, the glue markings and the machined markings define a striped and / or dotted pattern on the back of the plate of alternating glue markings and machined markings.

[0026] According to some embodiments, the striped pattern comprises stripes of glue markings and machined markings running parallel to the third side and the fourth side of the plate.

[0027] According to some embodiments, the striped pattern comprises stripes of glue markings and machined markings running parallel to the first side and the second side of the plate.

[0028] According to some embodiments, the striped pattern comprises stripes of glue markings and machined markings running parallel to the first side and the second side of the plate and to the third side and the fourth side of the plate.

[0029] According to some embodiments, the stripes of glue markings are thinner than the stripes of machined markings.

[0030] According to some embodiments, the front of one or more or each of the plates is provided with a waterproofing cover or layer at / in the factory.

[0031] According to some embodiments, the back of each plate is pre-formed to fit against an associated part of the wall and / or ceiling and / or window frames and / or door frames of the exposed surface of the inner room surface and any unevenness of these surfaces and / or parts onto which each plate is to be put with the back to arrange the front of each plate flat and straight and at the angle between any other adjoining wall board and / or ceiling board and / or window frame board and / or door frame board and / or at or in or between any of the corner after the inner room surface - except for window and door openings and any appliance, such as sockets, ventilation air ducts and / or ventilation air in- / outlets, electrical wiring for lights, drains etc. intended to be accessible from inside the room- is wholly covered by the preformed plates. According to some embodiments, the back of each plate is pre-formed to fit against an associated part of the wall of the exposed surface of the inner room surface onto which the plate is to be put with the back to arrange the front of each plate flat and straight and at the angle between any other adjoining wall board and / or at or in any corner of the inner room surface after the inner room surface is wholly covered by the pre-formed plates, except for window and door openings and any appliance, such as sockets, ventilation air ducts and / or ventilation air in- / outlets, electrical wiring for lights, drains etc. that has to be revealed or exposed to be accessible from inside the room.

[0032] According to some embodiments, the angle between any adjoining front of any plate adjacent or at or in any outer or inner corner of the inner room surface is close to perpendicular or perpendicular after the exposed inner room surface has been covered and flattened by means of the front of the pre-formed plate. By premanufacturing each plate by the system, a floor in a room may partly have a slope towards a drain at or in or on one area or part of the floor while the fronts of the plates on the wall and the plates on the floor with no slope and distanced from any drain at or in or on another area or part of the floor (actually extending with their fronts or upper sides horizontally) not being part of the separate sloping floor area towards the drain are still made to adjoin at angles which are close to perpendicular (according to tolerances within this technical area) or perpendicular as the premanufactured floor plates with no sloping have their upper exposed surface or front extending in parallel with the horizontal plane while the premanufactured wall plates extend with their fronts in parallel with the vertical plane when finally mounted in the wet room as the walls and the floor of the room are straightened up by the premanufactured plates being trued up compared to the rough and non-covered wall and floor surfaces while still enabling having some part of the floor with slope towards a drain if desired or applicable, such as in a wet room and / or a shower corner close to a wall. The angle between any adjoining front of any plate adjacent or at or in any outer or inner corner of the inner room surface is close to perpendicular or perpendicular at least to the horizontal plane after the exposed inner room surface has been covered and flattened by means of the front of the pre-formed plate.

[0033] According to some embodiments, the system comprises at least one packing adapted to pack the prefabricated plates in a pre-defined order according to the individual marking of each plate into at least one package of plates before the installation of each individual plate of the package in the room according to the predefined digital 3D representation.

[0087] DETAILED DESCRIPTION

[0088] Aspects / Embodiments of the invention are disclosed below by reference to figures 1 to 9.

[0089] The invention concerns a system 10 and method for coverage of at least a part of an inner surface 2 of a room 1 by means of a plurality of prefabricated and installed plates, boards or tiles 20. Such a plate, board or tile 20 comprises a back or back side 22, a front or front side 23, a first end or side 26, a second end or side 27, a third end or side 28 and a fourth end or side 29, see fig. 1 to 3, 5, 7, 8 and 9. These plate ends or sides or edges 26, 27, 28 and 29 could be arranged pairwise opposite each other as the back 22 and front 23 depending on the shape / preforming of the plate 20. These plate ends or sides 26, 27, 28 and 29 are arranged pairwise at an angle between each other, i.e., O° / perpendicular to each other, but any recess 24 made in them could have any angle less or larger than that depending on the final preformed desired shape of a recess 24 of the plate 20 to fit around any appliance 4 and / or door and / or window and / or alcove 6. The back 22 is adapted to be put and attached against the wall and / or ceiling and / or doorway and / or window recess surface(s) of the room 1. The front 23 is adapted to form the outmost or top layer of the room 1, 1' when finished but before any wallpaper or the like is applied as a final coverage. The front 23 of each plate 20 is not prefabricated / -formed as the back 22 and each front 23 after the plate 20 is put up is plane and flat and smooth over its whole surface. The same goes for plates 20 and their fronts 23 installed adjacent to each other. A plate end or side or edge 26, 27, 28 and 29 could be preformed at an angle y (see figs. 7, 8A and 8B) deviating from being perpendicular to each other, i.e., one or more or any plate end or edge 26, 27 could have any angle less or larger than 90° relative another plate end or edge 28, 29 or vice versa. In figs. 7 and 8B this angle y is shown with dashed lines and exaggerated for clarity as such an angle or slope towards a drain 4 at or adjacent or close to a wall is usually very small and difficult to visualise in 2D-drawings. In fig. 7, the angle y extends in the same or similar or in principle in the same way as shown in figs. 8A and 8B, i.e., both from the back 22 to the front 23 in the direction of the thickness of the plate 20 and wholly from the end or side or edge 28 along the front 23 and the bottom end or side or edge 26 to the end or side or edge 29. The angle y may - in some embodiments - depending on the associated room 1, 1' and location and shape of the drain 4, such as a square, rounded or an elongated rectangular drain (not shown) etc., only extend partly along or from the back 22 to the front 23 in the direction of the thickness of the plate 20, or only extend partly along or from the end or side or edge 28 along the front 23 and the bottom end or side or edge 26 to the end or side or edge 29. The angle y may in some embodiments only extend partly along or from the end or side or edge 29 along the front 23 and the bottom end or side or edge 26 to the end or side or edge 28.

[0090] These orientations of the angle y are also applicable to any other end or side or edge of a plate 20, such as between upper / top end or side or edge 27 and bottom end or side or edge 26 along the front 23 for fitting plates in corners and between floor and ceiling and / or between the back 22 and the front 23 along the thickness of the plate 20 and / or between the end or side or edge 28 or 29 along the upper end 27 and the front 23 depending on the shape and sloping of any adjoining ceiling plates 20. This angle y depends on the final preformed desired shape of the plate(s) 20 with the gradient or slope or angle y made before instalment to fit - preferably tightly - for example to any slope of one or more floor plates 20 around any drain 4 as shown in Fig. 8A in perspective and from the side in Fig. 8B reducing the need and amount of work to cover the joints if the adjoining plate edges and surfaces are as close to each other as possible. Each of the plate or board or tile ends or sides 26, 27, 28, 29 is adapted to be laid against or adjacent ends 26, 27, 28, 29 of other plates, boards or tiles 20 and / or a wall and / or a ceiling in the exposed room 1, the partly covered room or fully covered room is denoted 1'. This instalment of which ends or sides 26-29 against which other ends depends on the shape of the finished plate 20, i.e., end 26 on one plate could be arranged against any other end 27- 29 of other plates and vice versa.

[0091] In some embodiments, as shown in Fig. 9, one or more or each, i.e., all plates 20, to be installed in a room 1 have been provided with pre-made or pre-formed or prefabricated markings formed as two or more exemplary grooves or channels 200 on / at the back 22 in / at the factory before being transported to the site / room 1. These glue markings or glue channels 200 are configured to be filled with glue at the factory after the plate 20 and its back 22 is premanufactured and then these glue-filled markings 200 covered with release or backing liner / paper or cover layer 201 also at / in the factory before transport to the room 1.

[0092] In some embodiments, as shown in Fig. 9, one or more or each, i.e., all plates 20, to be installed in a room 1 have been provided with pre-made or pre-formed or prefabricated further markings formed as a plurality of dents and / or holes and / or depressions and / or dots 210 in an evenly distributed pattern, e.g., dotted pattern, on / at the back 22 in / at the factory before being transported to the site / room 1. These further glue markings or glue dents and / or dots 210 are also configured to be filled with glue but not at the factory, instead, these further glue markings 210 are void of glue until the plate 20 has been transported to the site for instalment and are intended to be filled or receive glue on-site just in time before installing the plate. These glue markings 200 and 210 are also intended to guide and show an installer where to put glue after a plate 20 is premanufactured and where glue is already applied as in the glue markings 200 and where the release lines 201 is to be removed or peeled off and in what amount the glue is to be applied just in time onto / in the further glue markings 210 on- site / in the room 1 before putting the back 22 of the plate 20 to / on / against the inside surface 2 of the room 1. In some embodiments, only the first glue markings 200, 201 are used while in other embodiments only the further glue markings 210 are used, even though Fig.9 shows an embodiment in which these glue markings 200 and 210 is used in combination on the back 22 of the plate 20. As exemplary distributions and / or patterns of these dots and / or dents 210, Fig. 9 shows an embodiment of more than four, e.g., five, larger dots and / or dents as circles visualised with dashed lines on the back 22, which embodiment may or may not be combined with the many small dots and / or dents shown in smaller circles with solid lines of fig. 9. Another example of an embodiment as shown in Fig. 9 could comprise more than five dots and / or dents 210, such as more than ten, e.g., twenty-four, smaller dots and / or dents 210 visualised with small circles in solid lines evenly distributed across the entire back 22 of the plate 20. If both the five or more big dots / dents 210 were applied in combination with fewer than or more than the twenty-four smaller dots / dents, the five big ones would of course be shown with solid lines. The number and distribution of these dots / dents 210 depend on the amount of glue to be applied / used but also on the size of the actual pre-formed plate 20, i.e., if the plate 20 shown in Fig. 9 would be half as long as shown, the number of dots / dents would for example be half as many shown on Fig. 9, i.e., about two to three or exactly two and a half big ones and twelve smaller ones, and if the plate would be doubled in size, the dots / dents 210 would of course also be doubled in number. However, the number of the dots / dents also depend on if both big and small ones are used, then the number would be twenty-nine dots / dents in total according to the embodiment shown, but could in other embodiments (not shown) be any other suitable number of bigger and / or smaller dots / dents as long as they are evenly distributed on the back 22 of the plate 20 to fulfil the glue demand.

[0093] The system 10 and method of the present invention enables installing the preformed plates 20 that form a 3D puzzle that both horizontally and vertically level out unevenness of inner wet room surfaces 2 where required while creating correct inclination / slope / rake of the upper inner wet room surface where required when finished to secure allowed / sufficient wet room drainage / water outflow. The inventive system 10 and method not only enables making uneven walls and / or ceilings of a room 1 even / plan / flat but also secures making the adjoining surfaces of a finally covered room and the actual room into an almost or as close to as possible orthogonal or square or rectangular or pa ra I lelepi peda I shape, i.e., two or more or all the adjoining surfaces of the room 1, 1' when covered by such preformed plates 20 meet or join at almost or very close to or exact perpendicular angles |3 (see figs. 4, 4A, 8 and 8A showing the finished angle |3 between a front 23 of a plate 20 and the horizontal floor after the plate is applied and attached to one associated part or wall area of the exposed inner surface 2 of a not yet covered part or area of the room l and being applicable to all finished and adjoining surfaces, such as between a wall and the ceiling and in any inner and / or outer corner and / or at or around any drain 4 of the finished room 1' as shown in figs. 4 and 4A) during and after having installed the plates 20, both partly and / or over the whole inner room surface 2 made up of the front or front side 23 of each plate 20.

[0094] The system 10 optionally comprises points of reference 3 to be laid out or which are put on the inner room surface 2. As no inner room 1 and / or inner surface 2 of such a room is exactly alike any other inner room 1 or its inner room surface 2 after building or renovating and anew, each inner room and its inner room surface is unique in regard of measures / dimensions, slopes / inclinations / gradients, flatness, warping, levels, positions or placements of electrical wiring and / or socket(s) and / or ventilation air in- / outlet(s) and / or duct(s), light appliances and / or drain(s) 4 that should be revealed and accessible from inside the room when the room surfaces 2 are finally covered (e.g., by wall paper or the like), or holes / openings / drains 24 as parts of the floor and / or walls and / or ceiling of the room 1, and the actual inner room 1 and inner room surface 2 are scanned each time by a 3D scanner 30. The location of the holes 24 and their sizes and shapes are used for making corresponding holes and / or recesses in the plates or boards or tiles 20 as shown in figs. 1, 2, 3, 5, 6, 7, 8, 8A and 8B. This scanner and scanning 30 is adapted to scan the exposed inner room surface 2 being at least part of the floor, walls and / or ceiling of the room 1 including inner and outer corners all over the room 1 into a plurality of points of measuring 31. However, reference points 3 are usually only required and applicable to use on a floor when scanning the floor, not for a wall and / or a ceiling, but could in some aspects improve the scanning of the wall and / or the ceiling. Scan 30 is done to create a digital 3D map representation 32, 33, 34, 35, 36, 37 of the exposed inner room surface part 2 to be covered including its existing angles a between all adjoining exposed surfaces and at or in existing inner and outer corners of the scanned room and the unevenness of all the exposed room surfaces warping, positions or placements of electrical wiring and / or socket(s) and / or ventilation air in- / outlet(s) and / or duct(s), light appliances and drains 4 that should be revealed and accessible from inside the room when room surfaces are finally covered (e.g., by wall paper or the like) or the like being common entities in rooms 1. The exposed inner surface 2 could be part of a staircase and / or stairs to be covered with such prefabricated plates, boards and / or tiles 20. The exposed inner surface 2 could be other parts, such as thresholds, i.e. doorsteps or doorways or window recesses; or skirting boards for floors, walls and / or ceilings; or one or more steps of a stair case or part of one or more steps or the whole stair case and / or stairs themselves, to be covered with the prefabricated plates, boards and / or tiles 20.

[0095] In figs. 5 and (top right views) and 8, the underside 22 is shown adapted (by processing) to the exposed wall or ceiling or floor surface 2 of the inner room surface 1. Each plate 20 is usually adapted on only its underside 22 (into an exemplary shown shape or profile in solid lines of figs. 5, 8) and not on its front or front side 23 to fill out any unevenness on any associated exposed room surface 2 and fulfil the sloping criteria with perpendicular angles |3 for a finally covered room 1' instead of any existing non-perpendicular angle a of a not yet covered or at least not fully covered room 1.

[0096] The inventor has invented a system 10, 11, 12, 13, 14 and a method to adapt and pre-fabricate coverage material into "tailor-made" wall and / or ceiling and / or doorway and / or window recess coverage material of relevant plate material 20 being divided into, for the exposed inner surface part 2, relevant geometrical parts that subsequently, during installation in the room 1, are distributed in a predefined order over the inner surface. Each plate 20 is prefabricated by forming / shaping only its back or underside 22 and not the front 23, except for making holes and / or recesses 24 for appliances to be accessible from or shown inside the room 1, 1' when covered by these plates 20 to adapt the shape and dimension of each individual plate to the specific inner surface 2 and the 3D space required in the wet room 1. The inventive pre-fabrication process is divided into several partial processes. A first process concerns scanning 30 the inner surface 2 for the creation of a CAD drawing being unique for the inner surface 2 and room 1, which is used to control the pre-manufacturing of the plates 20, see fig. 5, visualized in box 11. A second process concerns applying the CAD drawing into a relevant CAM processing scheme to be used by appropriate manufacturing equipment 40, 50 to control and perform manufacturing of each actual plate 20, see the top right view and the two lower right views of Fig. 5 visualized in box 12, and the two upper left views in Fig. 6. A third process 11 concerns marking each pre-fabricated and finished plate 20 and packing them in a correct order in one or more packages 21 and / or set of packages 25, see the three upper right views visualized in box 14 and / or all the four upper views in Fig. 6 (in this process a unique installation instruction is also compiled and enclosed in the package 21). A fourth process 12 concerns unpacking each prefabricated and finished plate 20 in correct order from the packages 21, see the three lower left views of Fig. 6 visualized in box 15 (in this process the unique installation instruction is used to correctly install the plates 20 in the room 1 and on the inner surface 2 in the correct predefined pattern into the straightened up room 1'). The process of box 14 and 15 in combination with the transport 70 is visualized in box 13 of Fig. 6.

[0097] The scanner 30 is a portable 3D scanner that could be handheld by an operator 5 or user or installer of prefabricated plates 20 during scanning. The scanner 30 is laser equipment and / or one or more cameras configured for 3D scanning of surfaces / volumes 2. The room 1 may or may not have a door and / or a window 6 and if the room is a bathroom, it usually comprises at least one washbasin, toilet and / or shower or shower bath and / or bathtub and drain(s) 4. Before the inventive system 10 and method are applied to the room 1, which could be a residential room or apartment and / or an office or office space having no surface layer, the room is prepared, e.g., by cleaning, for installation of surface coverage, i.e., the pre- fabricated / -formed plates 20. Alternatively, one or more digital cameras 30 is / are used for creating one or more 3D models of the surface 2 by photogrammetry, whereby one or more "clouds of measuring points" is / are created by means of at least two or a plurality of digital images, enabling to read / scan the surface 2 in a corresponding way as the 3D scanner 30. Alternatively, structured light 3D scanners or "white light" 3D scanners, most structured light 3D scanners using a blue or white LED projected light is usable. These 3D scanners 30 project a light pattern 31 consisting of bars, blocks or other shapes onto an object. The 3D scanner 30 has one or more sensors that look at the edge of those patterns or structure shapes to determine the objects 3D shape of the surface 2. Using the same trigonometric triangulation method as laser scanners, i.e. the 3D scanner 30, the distance from the sensors to the light source is known whereby one or more "clouds of measuring points" is / are achievable accordingly as for the techniques above. Structured light scanners can be tripod-mounted or handheld as shown in fig. 1.

[0098] The inner surface 2 of the room 1 to be covered by the prefabricated material in form of plates or boards and / or tiles 20 are scanned by the portable scanning equipment 30. Before doing this the inner surface 2 to be covered has been provided with reference points 3 - if required - and horizontal lines and / or vertical lines, e.g. a digital water / spirit level with known length can be used or a laser. To be able to pre-fabricate the plates 20 to cover the inner surface 2 as a final result a design of a digital manufacturing scheme or programme for pre- shaping / pre-manufacturing these plates is performed by usage of the scanned data in the scanner 30. This data is forwarded to a CAD / CAM system 40 after scanning, e.g. a suitably equipped PC, see figs. 1, 5, and 7.

[0099] The adaptation to and / or hole / recess making in a plate 20 for any electrical wiring and / or socket(s) and / or ventilation air in- / outlet(s) and / or duct(s), light appliances, alcoves, or built. in shelfs, drainage, water inlet / outlet 4 on the inner surface 2, any shower walls or similar compartment in the room 1 and any levelling in relation to adjacent space / -s is / are put into the digital manufacturing scheme via the scanning 30, 31 as shown in figs. 1 and 5 (top left view). In the digital manufacturing scheme or programme, the inner surface 2 being scanned into a 3D representation 32 including the hole / recess making is divided into a suitable number of digital pieces 34 of a digital grid pattern 33, similar to a digital puzzle, and into digital representations 35, 37 of each of the plates 20 in 3D to be physically manufactured accordingly. The plates 20 are suitably identified, e.g. by individual number markings, both digitally and physically to be easy to install according to the predefined grid pattern 33 at the final site, i.e. the actual room 1. One possible pattern is to put up the first plate 20 to the furthest right or left as seen from a corner or a door and / or a window 6 to establish a starting point or "start line" to ensure that the serial of plates are not starting to diverge in any direction else than the one following the floor and / or ceiling in a straight and parallel line or row and then putting up and attaching out subsequent plates 20 from / to the right of the first plate 20 as shown in figs. 2 to 4, 5 (bottom left view where the plates 20 are installed in a clock-wise order as also done in figs. 8 and 8A), 6 (bottom left view where the plates 20 are installed in a counter-clock-wise order).

[0100] Figures 1, 5, 6, and 7 show the scanning by scanner 30 into data forwarded to the CAD / CAM system 40 receiving the points of measuring 31 from the 3D scanner 30. Figures 5, 6, and 7 show the CAD / CAM system 40 creating the digital 3D representation 32 of the part of the inner room surface 2 based on the points of measuring 31 and transforming the digital 3D representation 32 into the grid pattern 33 with a suitable number of the individual digital plates 34 with unique identification and dimensions and a CAM controlling manufacturing workflow to manufacture each individual plate 20 accordingly. In Figures 5 and 6, at least one CAD / CAM controlled machine 50 is shown receiving the CAM controlling manufacturing workflow and physically manufacturing and marking the plates 20 individually as unique entities accordingly. Figures 3 and 6 also show the installation of each individually prefabricated plate 20 on the exposed inner surface 2 in the room 1, 1' according to the predefined digital 3D representation 32, 33, 34, 35, 36, 37.

[0101] The individual plates 20 in Figs. 1 to 4, 5, 6, 7, 8, 8A, 8B and 9 are handled so that each plate is individually formed / manufactured and packed correctly in a correct order before being transported to the room, and in a correct package 21, and laid out at its correct position in the room / space / part 1, 2 and plates that are intended to together make-up e.g., a ventilation in- / outlet and / or a hole 24 around a drain 4, i.e. an opening for it is denoted as a pair.

[0102] The methods of pre-fabrication / pre-manufacturing of the plates 20 could be subtractive and / or additive manufacture, such as cutting, milling, turning, e.g. wood peeling, casting or moulding, e.g., of plastic or composite or stone or ceramic tiles, 3D printing, or lamination of plates in one or more steps or any method being a combination of one or more of the above. In some aspects, one or more plates 20 configured for instalment in wet rooms comprises a water proofing layer 230 attached or affixed over / onto / on or covering the front 23 at / in the factory before being transported 70 to the site and room 1 for instalment (see Figs. 8A and 8B). In some aspects, one or more plates 20 configured for instalment in wet rooms are prelaminated with a water proofing layer or cover 230 over / onto / on the front 23 at / in the factory before being transported 70 to the site and room 1 for instalment (see Figs. 8A and 8B). In some aspects, one or more plates 20 has / have a water proofing layer or cover 230 adhered over / onto / on the front 23, e.g., by gluing, molding and / or melting, at / in the factory before being transported 70 to the site and room 1 for instalment (see Figs. 8A and 8B). Hence, if a pre-made plate 20 comprises the watertight layer 230, that layer forms the outmost surface of the front 23 as a two-layered front or exposed plate surface of a part of the room 1' after instalment and the whole room when all plates are installed. By providing such pre-made water proof plates 20 by means of the two-layered front 23, 230, only joints and transitions between adjoining plates and other appliances, such as a drain 4 in a wet room, have to be covered and sealed by additional water proof layering and / or water sealing components to achieve a safe wet room meaning that manual work on-site is much less demanding ergonomically and much less time consuming.

[0103] Figures 1 to 6, 8, 8A and 8B show the inventive system 10 and method and practical handling of the pre-fabricated plates 20 (fig. 7 shows the digitalization), i.e. concerning packaging 60 the plates 20 into one or more packages 21, loading 61 the packages 21 onto a transport 70, e.g. a truck / lorry or fork lift truck, unloading 62 one or more plate packages 21 from the transport 70 and moving 63 one or more of the plate packages 21 to the installation site, e.g. just outside the room 1, and finally unpacking 64 the plate packages 21 for final installation of individual plates 20 on the inner surface 2 of the room 1.

[0104] In addition to the above parameters of dimensions etc. used to pre-form the back 22 or the back 22 and a side 26, 27, 28, 29 of the plates 20, the designer could add additional information into the digital manufacturing scheme or programme, e.g. apartment or room number, address of delivery, any marking or identification of their own, such as order number, or the like. This additional information enables providing basis for invoicing, packing and transport. The invention enables performing so many steps as possible in one operation or process beforehand in / at the factory to eliminate as many manual steps as possible and reduce waiting time, e.g., to await primer and / or liquid membranes to dry before commencing next step, on-site, and also reducing the effort of attaching the plate(s) 20 by minimizing the amount of glue that manually has to be applied on-site and / or reducing the effort of manually applying the water proof layering in wet rooms on-site, and at the same time increase the quality of the work and final resulting surface coverage.

System 10 in another aspect comprises at least the transport 70 to deliver the at least one plate package 21 at one or more rooms 1 before installing of each individual plate in the room according to the predefined digital 3D representation 32, 33, 34.
