The invention relates to a lining unit with a bottom part and side parts standing upright starting at the bottom part, wherein the bottom part and the side parts are made of a water-tight film.
Lining units of the type in question are known in the prior art.
They serve the purpose of sealing wet areas in buildings, in particular wet rooms with, for example, bathtubs, showers or the like. The lining unit prevents moisture from entering a wall or a floor of the building, respectively, or room, respectively.
The approach of the prior art is usually such that a lining unit is made up on site of a plurality of individual elements, namely of a bottom part, several side parts as well as connecting means, which connect the bottom part and the side parts to one another. In particular film strips are used here, which are adhered or welded, respectively, to the bottom part or the side parts. More than, for example, ten individual elements, which are to be connected, thus often result on site. Pre-formed corner formations are also known, which are connected to the bottom part or the side parts, respectively. In an assembled state of the lining unit, a preferably complete, then one-piece lining of the room then results, in particular comprising a liquid-tight coverage of a room floor.
Pre-formed lining units are furthermore known, which can each be inserted in an assembly space in the manner of a sealing tub. In an assembled state, a certain coverage of an assembly space side surface of a few centimeters also develops in addition to a coverage of the assembly space floor, wherein a circumferential sealing section protruding beyond the assembly space side surface can also be formed for the possible integration of the film layer of the lining unit into a surrounding sealing plane, for example in the area of a door opening of a shower cubicle.
The DE 10 2014 013 743 A1 discloses, for example, a bottom film, which covers the entire base surface of an assembly space and has erected edges on its rims. The bottom film is pre-fabricated in the factory and can be assembled as one piece underneath a visible floor covering, for example underneath a wet cell. The erected edges of the bottom part are adhered or welded on their abutment points.
In terms of the above-described prior art, it is the object to further improve a lining unit of the above-mentioned type, in particular in terms of an improved moisture protection as well as simplified ease of assembly in different assembly spaces.
A possible solution is initially specified by means of a lining unit, in the case of which the bottom part is formed in one piece with at least one side part, wherein the lining unit is formed in a pre-fabricated manner for lining a room, such as a wet room, wherein a dimensioning of the bottom part according to a surface of a floor of the room is at hand, and wherein a dimensioning of the respective side part according to a surface of a wall, optionally with an adaptation in terms of an opening, such as a door, of the room, is at hand, wherein the side parts completely border the bottom part and the bottom part and the side parts each have an inner and an outer surface, wherein the inner surfaces are further formed with an adherence structure for an attachment of tiles, wherein the side parts further form angles with one another in a cross section parallel to the floor with respect to their inner surfaces or outer surfaces or merge in a rounded manner and have different heights, namely at least a first and a second side part have a first height and a third and optionally further side parts, including in particular an opening side part, have a second height, wherein the first height corresponds to a multiple of the second height.
With respect to the first side parts, the lining unit is thus in particular adapted to those rooms, in which moisture does not only occur in a bottom area but also in the area of the side parts. This is the case, for example, in conventional shower cubicles or also shared shower rooms, as is known, for example, from swimming pools. Such a room can also be an entire bathroom, guest toilet room or a different wet room. So as not to allow water, which hits, for example, the side parts of a shower or of a bathroom, to enter into the wall of the room in an unprotected manner, it is common to tile them. This usually takes place up to a height, which lies approximately 30 cm above the usual position of a shower head. The attachment of tiles, however, can also take place across an entire room height, up to a room ceiling.
In accordance with its intended purpose and place of use, the lining unit is adapted so that it forms a base in particular for those areas of the room, which can potentially come into contact with water. In addition to the room floor and room side walls, they can also be room dividers, for example, which are used, for example, in common shower rooms, swimming pools or also private bathrooms. The side parts of the lining unit are accordingly formed to not only be fastened to room side walls but also to intermediate walls or intermediate elevations, respectively, which rise up from the room floor in particular parallel to the room side walls, such as, for example, the above-mentioned room dividers. The heights of the side parts of the lining unit can thus vary significantly from one another. The height of one side part can be, for example, a few millimeters, for example in the area of a door opening or in the area of an entrance and exit of a floor-level shower cubicle, up to a usual room height of 2.0 m, 2.1 m, 2.2 m, 2.3 m, 2.4 m or beyond that, whereby it goes without saying that intermediate values of these heights are also conceivable.
A proposed lining unit is thus formed as a whole so that a first and a second side part thereof have heights, which significantly different from one another, namely a first height of a first side part corresponds to a multiple of a second height of a second side part. In the case of a first height of 2.20 m and a second height of 0.01 m, it follows for example that the first height corresponds to 220 times the second height. Multiples lying significantly above or below this are also possible. Provided that according to a different embodiment, a second side part abuts, for example, against a room divider and thus has, for example, a second height of 1.00 m, 2.2 times or a ratio of the first height to the second height of “2.2 to 1”, respectively, would result in the case of a first height of a first side part of 2.20.
The lining unit can be formed so that two adjacent side parts cover an outer corner or inner corner of the room. A lining unit can furthermore also be formed so that it covers an outer corner as well as an inner corner of the room. The shape of the lining unit, in particular the bottom part thereof, is a function of the individual conditions of the respective room. The lining unit can in particular also be designed in a standardized manner to certain rooms, for example bathing rooms of ship cabins, guest toilet rooms or the like.
Depending on the spatial conditions of the room or of a corner provided therein, respectively, in which in particular water hits the side surfaces, two or also three first side parts can be connected to one another, which form, for example, a corner area of a shower or of a toilet room.
The assembly of the lining unit in the room in particular takes place so that a tile adhesive, for example, is initially applied to a floor of the room as well as the side surfaces of the room, at least in such an area, to which the bottom part and the side parts of the lining unit are to later be fastened. The lining unit is subsequently placed into the room so as to correspond in shape and, for example, tile adhesive is applied, in turn, to the surfaces pointing inwards into the lining unit, in order to then fasten tiles thereto.
The lining unit can also be assembled by means of an applied sealing adhesive or a polymer-based adhesive. With respect to the assembly in the room, the lining unit can furthermore be formed to be self-adhesive.
The film itself is made of a moisture-proof material, which has thermoplastic components. For example, a polyethylene film can be used here. The film is preferably made so that the bottom part transitions seamlessly into the respective side part and the adjacent side parts are connected to one another via side seams, which are formed by means of adhering or welding.
Before the start of the assembly work, the lining unit as a whole can be present in one piece. To simplify the assembly in the case of comparatively very large surfaces, the lining unit can also be present in two or several pieces but in a number of individual elements, which still permit a simplified assembly. Not more than seven, eight or nine individual elements are thus preferably parts of the lining unit, wherein an individual element can optionally have several side parts or optionally one bottom part with one side part or further optionally also only one side part. Usually, the lining unit does not yet have or the elements of the lining unit do not yet have, respectively, any openings, through which, for example, pipes or fittings can be guided. In an initial state, the lining unit is still free from openings in this respect. It can also be provided, however, that already pre-fabricated openings for pipelines or other connecting pieces are formed in the bottom part and/or one or several side parts. During the production of the lining unit, the specific conditions of the room, for example on the basis of a dataset, are already considered in this respect. For the formation of, for example, a passage in the bottom part or one of the side parts, a severance of the film forming the lining unit is made at the provided point, wherein the severance has a smaller dimension than the diameter of the pipe, which to be guided through later, for example. The lining unit is then pulled over the pipe during the assembly, in particular by elastically widening the severance, so that a sealing connection results directly by means of the film.
By means of an optionally multi-piece design of the lining unit, an adaptation, which is favorable with respect to handling, can also be attained with higher tolerances in the room to be lined. In the case of a rectangular room, a, for example, four-piece lining unit (an individual element with a bottom part and side part formed in one piece therewith as well as three side parts as further individual elements) can thus be present, which is placed into the room corners and the tolerance in the corner areas is absorbed via an overlap area of the individual elements to one another.
A lining unit, which is favorable with respect to production and handling, for lining a room on the basis of a film is created by means of the proposed formation. The lining unit is thereby preferably formed in one piece in terms of the bottom part as well as in terms of at least one of the side parts and the sealing sections adjoining the side parts. No transitions or only slight transitions, which are to be produced separately at the place of installation, in the form of, for example, adhesive or welding transitions therefore result between the bottom part and the side parts in the assembly state due to the pre-formed film layer, which forms the lining unit.
Even the sealing of an object guided through the bottom part or a side part, for example of a pipe or of a fitting, can be carried out in a simple way with respect to handling by means of the proposed lining unit, in that the flexible, resilient material of the film is used directly as a type of sealing sleeve for the abutment against the object. For this purpose, the film, on the basis of which the lining unit is produced, is severed in the area of the passages to be carried out, so that a notch or a recess results in the film layer, which has a smaller length (in the case of a notch) or a smaller diameter (in the case of a recess), respectively, than the outer diameter of the object to be guided through. In response to the guide-through of the object through the opening of the film, an elastic widening of the opening thus results in such a way that the film material can cling in a grommet-like manner, at least in a lip-like manner towards the recess of the notch that was made, to the outer surface of the object. The film material of the lining unit surrounding the object to be permeated is accordingly used as grommet or sealing sleeve. A further arrangement of separately formed grommets or sleeves is not required, wherein-if desired-a severing of the bottom part or of the side part can nonetheless also still be made on site as part of the lining of the room and installation of the pre-formed lining unit. In terms of the permeation position of the object, a universal, locally flexible arrangeability is thus created. As explained, required openings can thus either already be formed beforehand by the manufacturer of the lining unit or also still later by the assembler.
According to the above-proposed formation, at least one or two side parts of the lining unit are formed significantly higher than at least one third or further side parts, which are, for example, not provided for fastening to a room-high side wall of the room but abuts only against a relatively low rim edge of a floor cutout in the area of, for example, an exit of a floor-to-ceiling shower tub or of a door of the room. Short side parts of this type, here referred to as second side parts, have, for example, a second height of a few centimeters, for example 1 to 10 cm. The short second side part can furthermore optionally also have a height excess of additional centimeters in order to form a safety reserve beyond the rim edge. The second side part can, for example, also be folded over in order to be placed over a rim of the floor cutout and in order to find sealing connection to a floor covering there.
It is proposed here that the first height of the first side part is at least 10 times as high up to 50 times as high as the second height of the second side part. Provided that the second height of the second side part (short side part) is 4 cm, for example, the first height of the first side part (high side part) can be, for example, up to 50 times the second height, for example 200 cm, so that almost or completely the entire wall height of the room is covered by the high side part of the lining unit and protects against moisture there. Depending on the installation situation of the room, it is optionally also not required to cover the entire height of a room with the first side part of the lining unit. In this case, the first side part can, for example, also only have a height of 50 cm to 100 cm, 50 cm to 150 cm, 25 cm to 50 cm or further height dimensions. It goes without saying that other heights within the above-mentioned limits are also possible, in particular in centimeter increments, i.e., for example 30 cm, 31 cm, 32 cm, etc.,
It is furthermore proposed that the first height exceeds half a dimension of a largest side length of the bottom part. The first height is preferably at least approx. 1.50 m up to 2.50 m. The proposed first height of the first side part is suitable in particular in the case of lining units, which are to be attached in showers or entire shower rooms, namely where water hits directly against a wall surface. The attachment height of a shower head or also the ceiling height can be considered thereby, wherein the first height of the first side part preferably corresponds to an upper rim edge of a tiling. In particular a first height of approx. 1.50 m up to 2.50 m can result thereby, wherein it goes without saying that intermediate values within these specified height limits are also conceivable. With respect to a size ratio of first height of the first side part to the side length of the bottom part, ratios can result, which go significantly beyond the specified side ratio of 1:2, in the case of shower cubicles or relatively small bathroom spaces of, for example, ship cabins. For example, a ratio of 1:1 or beyond can also result.
A further height ledge above a sanitary unit to be installed, such as, for example, a sink or toilet, can also result, above which sanitary unit no sealing up to the ceiling height is required. The height ledge can result here, for example, 20 cm above the sanitary unit to be installed.
A further height ledge can additionally be provided by means of the connection of a bathroom window or also by means of the sealing of a shower, for example as shelf for shower items.
According to a further idea of the invention, a lining unit is specified, in the case of which the side seam formed between two adjacent side parts is formed by means of two rim areas of the adjacent side parts, which are placed one on top of the other, wherein one of the rim areas is folded, so that the side seam has a three-layeredness. The lining unit can furthermore have the features of the above-proposed embodiment but can also be provided independently of a certain side dimension of the side part.
The proposed three-layeredness of the side seam formed between adjacent side parts ensures a particular stability of the lining unit in particular in the corner areas on the one hand and also an improvement of the moisture protection on the other hand. The three-layered formation of the side seam can be provided between adjacent first side parts as well as between adjacent second side parts or between a first side part and a second side part. During the production of the side seam, the rim areas of the two adjacent side parts are initially placed one on top of the other in the same direction so that the free rim edges of the rim areas point in the same direction. A side part is then folded over in the direction facing away from the adjacent side part in order to attain the proposed three-layeredness. In the folding direction, the rim areas of the adjacent side part can have a width of several millimeters up to a few centimeters. A placement one on top of the other in a range of 5 mm to 15 mm is particularly recommended. The width refers to that direction, which corresponds to the circumferential direction of the bottom part or the entire lining unit, respectively.
It is recommended to initially connect the rim areas of the adjacent side parts, which are placed one on top of the other, to one another, for example by means of adhering or welding, and to then first fold one of the rim areas, so that the rim areas of the adjacent side parts, which are placed one on top of the other, abut against one of the side parts. The rim areas, which are placed one on top of the other and which are already connected to one another, can then be connected to the side part, in particular also again by means of adhering or welding.
In the case of the above-mentioned embodiment, it can in particular be recommended that the side seam has a depression with depression rim edges, viewed from outside of the lining unit. The side seam can thereby either have a single depression or also a plurality of consecutive depressions in the longitudinal direction of the side seam, which, based on their longitudinal extension, extend in the direction of the erected side seam of the side part. The depression can be created in that an in particular rod-shaped pressing element and/or heating element is placed onto the side seam during the production of the side seam, in particular the adhering or welding process. The depression is then introduced by means of pressure and/or heat into the side seam, which thus visibly and/or tangibly stands out from the remaining material of the side seam as well as of the side part. Depression rim edges, which visibly or tangibly stand out from the remaining material of the side seam or of the side part, respectively, result around the depression. The depression including the depression rim edges ensures a particular stability of the side seam and thus also of the entire lining unit. The moisture protection in the area of the side seam is furthermore also improved thereby.
According to a further embodiment of the lining unit, which can be significant in connection with the above-mentioned embodiments as well as independently thereof, it is proposed that the lining unit has an insertion part in a transition area between the bottom part and at least one side part, wherein the insertion part forms a subarea of the bottom part and a subarea of the at least one side part. The proposed insertion part can be provided in particular for the formation of an outer corner or inner corner of the lining unit.
The insertion part can also include one or several complete side parts and not only one or several subareas thereof. It is essential that the bottom part does not transition seamlessly into the adjacent side part in the area of the insertion part but initially adjoins the insertion part, which then provides the seamless transition into the side part.
For forming an outer corner or also of an inner corner, the insertion part can in particular have an essentially L-shaped extension, wherein the legs of the L shape, which are angled towards each other, can each be placed against a side wall of the room. The adjacent side parts of the insertion part can thereby be formed so as to in particular seamless merge, optionally in one piece, so that no seam is created on the corner or the lining unit formed therewith. An absolute tightness of the corner area of the lining unit is created thereby. The formation of the side seams on the adjoining side parts of the lining unit can then take place spaced apart from the corner area, namely where the insertion part transitions into the adjacent side part.
It is proposed that the subarea of the bottom part formed by means of the insertion part is connected to an adjacent subarea of the bottom part via a bottom seam. According to this formation, the bottom seam between the insertion part and the bottom part thus does not lie in a corner area of the lining unit but rather in the area of the bottom part, where the mechanical stress of the lining unit is smaller than in a corner area.
The lining unit can further be formed so that recesses are formed in the corner areas between the bottom part and two adjoining side parts, which, following the assembly of the lining unit in the room with specifically shaped insertion parts, for example inner corners or outer corners, are adhered on site. In the area of the cutout, a seal can only be attained with adhesion of the insertion part.
In order to bridge tolerances, the rim area of the lining unit can furthermore be made of a material, which can be plastically deformed. For example, a rim strip of a stretchy and technically tight, but non-resilient material can be provided. For example, a strip of butyl rubber can be provided in this respect, or an area having a stretch reserve, which can be provided with a restoring hindrance, for example in the form of an insert (for example a wire). Accordingly, the insert is preferably plastically deformable without or without essential resilient property. As part of the installation, the lining unit can thereby be stretched into the corner areas of the room so as to compensate tolerances and can be adhered there, preferably in a tension-free manner.
The bottom seam can be formed in several pieces, the insertion part can in particular have several bottom seams, which are oriented transversely to one another. For example, a first bottom seam can be formed parallel to an adjacent side part of the lining unit, while a second bottom seam is at a 90 degree angle thereto and runs parallel to an adjacent side wall of the lining unit. The bottom seam or the bottom seams, respectively, can furthermore run transversely to side seams, which connect adjacent side parts of the lining unit or subareas of the side parts to one another. A point of intersection between the bottom seam and the side seam is in particular further formed by a corner of the lining unit, so that neither the bottom seam nor the side seam lie on the corner of the lining unit.
The bottom seam can be formed by two rim areas of the adjacent subareas of the bottom part, which are placed one on top of the other. In a particularly simple case, a two-layeredness of the bottom seam thereby results in that the rim areas do not abut against one another edge-to-edge with their rim edges but overlap to a certain extent. The overlap can preferably be several millimeters up to a few centimeters. Based on a direction transversely to the longitudinal extension of the rim edges, the overlap exists in particular over a width of 5 mm to 15 mm. It can generally furthermore also be provided to also form the bottom seam with a three-layeredness, in particular as this has been described above with respect to the three-layered side seam between adjacent side parts.
All of the embodiment variations of a lining unit described here can provide that the film of the lining unit is made of polyethylene (PE). Polyethylene can be excellently extruded to a film and offers an outstanding flexibility in order to form seamless transitions between the bottom part and the side parts of the lining unit but optionally also between adjacent side parts of the lining unit. Polyethylene is furthermore impermeable to liquids and mechanically stable, so that the lining unit also withstands a mechanical stress during the assembly process. In addition to polyethylene, however, the film can also be made of other materials or material mixtures. For example, the formation of polypropylene (PP) or polyethylene terephthalate (PET) is also conceivable.
The film is preferably laminated with a non-woven fabric. The lamination preferably exists in particular on both sides, i.e. on an outer surface of the lining unit as well as on an inner surface thereof. The lamination can preferably have a polypropylene non-woven fabric. On the one hand, the lamination serves the purpose of fastening the lining unit to a floor or a wall of the room, respectively, as well as, on the other hand, of fastening, for example, tiles to the lining unit itself. The lamination, for example formed as non-woven fabric, is excellently suitable to absorb, for example, a tile adhesive and to furthermore then effect a fastening to the structure or to be covered with tiles.
In this respect, material combinations of, for example, a thermoplastic elastomer (TPE), further for example an ethylene vinyl acetate copolymer (EVA), possibly also in combination with polyester non-woven fabrics. Different materials can also be used for sealing, for example, pipe penetrations and for the surface. Instead of a non-woven fabric, an alternative coating with a material is also possible in order to ensure the adhesion of the adhesive.
To avoid an infiltration due to the capillary effect of the non-woven fabric, capillary barriers can also be installed in the area of the non-woven fabric.
The formation of the film of polyethylene as well as the in particular two-sided lamination thereof is not only significant for the above-proposed embodiments of lining units but also for lining units in general terms, which do not have the above-described characteristic features of the height ratios of the side parts, of the three-layeredness of a side seam or the formation of an insertion part between the bottom part and at least one side part.
With respect to the side seam as well as with respect to the bottom seam, it can additionally be provided that the side seam formed between adjacent side parts and/or the bottom seam connecting the insertion part to the adjacent subarea of the bottom part is welded. The side seam or bottom seam, respectively, can in particular be produced by means of ultrasonic welding. Other welding methods can likewise be used. Alternatively to a welding process, however, the side parts and/or the insertion part can also be integrated into the lining unit by means of an adhesion.
A further embodiment provides that, viewed from outside of the lining unit, the side seam has a depression with depression rim edges. This proposed formation of the side seam is significant with respect to the above-mentioned embodiments of a lining unit as well as independently thereof. The formation of the depression with depression rim edges serves the purpose of a particular stiffness of the side seam as well as of an increased tightness of the point of intersection between the adjacent side parts. The depression can be produced by means of pressure and/or heat exposure on the side seam, wherein tangible and/or visible depression rim edges result. The side seam can either have only a single, elongate depression along the side edge of the lining unit or a plurality of depressions lying one behind the other in the longitudinal direction.
It can additionally be provided that the bottom part of the lining unit has a pre-fabricated rectangular, in particular also square, basic shape with a base surface of 80 cm times 80 cm or 90 cm times 90 cm. Basic shapes of this type are in particular common in the case of shower trays. The bottom part can furthermore also have a pre-fabricated basic shape of 5 ft×8 ft, which corresponds to a standard size of guest bathrooms in the USA. In that sense, the lining units can already be pre-fabricated in such a way with respect to the size of the bottom part that they already readily fit a plurality of application areas. It goes without saying that in addition to the above-mentioned shapes and dimensions, other shapes and dimensions can also be specified for the formation of the lining unit.
Alternatively, the bottom part can also have a cutout, into which a shower plate can be inserted, which was already factory-sealed.
The lining unit can in particular be used in a wet room. However, a lining unit, which is favorable with respect to handling and assembly, is furthermore also advantageous in rooms, in which web-shaped technical products, such as, for example, impact sound or decoupling webs, are optionally installed on the floor.
As a whole, the design according to the invention of the lining unit results in a simplification of the installation, with increased safety in particular in terms of the tightness, wherein tolerances in the room at hand can be compensated in an advantageous manner.
In terms of the disclosure, the above- and below-specified ranges or value ranges, respectively, or multiple ranges also include all intermediate values, in particular also in 1/10 steps of the respective dimension, optionally also without dimension. For example, a specification such as 0.1 times to 0.5 times also includes the disclosure of 0.2 to 0.5 times, 0.4 to 0.5 times, 0.3 to 0.4 times, etc., On the one hand, this disclosure can serve the purpose of limiting a mentioned range limit from below and/or above, but alternatively or additionally also for the purpose of disclosing one or several singular values from a respective specified range.
The invention is described below on the basis of the enclosed drawings, which only represent exemplary embodiments, however. A part, which is described only based on one of the exemplary embodiments and which is not replaced by another part in the case of a further exemplary embodiment due to the special features emphasized there, is thus also described for this further exemplary embodiment as at least possible available part. In the drawings:
What is illustrated and described, initially with reference to
Here, the lining unit 1 has, for example, a bottom part 4, two first side parts 5, 6, which reach up to an upper tile rim 30 of a tiling only in an exemplary manner here, and two second side parts 7, 8 lying opposite the first side parts 5, 6. The second side parts 7, 8 are significantly shorter than the first side parts 7, 8 and only reach up to or just over a floor plane 27 of the room, here for example of the bathroom, on which tiles 32 are attached.
Here, the room 2 has, for example, a box-like indentation 25 in the floor of the structure. As illustrated here, the room 2 can further have a room floor 26, which preferably results from a raw floor of the structure and which runs so as to be offset downwards in the vertical direction with respect to the floor plane 27 of the room, which is covered with the tiles 32. From the room floor 26 up to a room ceiling 31, the room 2 has a room height c.
As illustrated, the room 2 can be formed to be square, for example with dimensions of 80 cm times 80 cm or 90 cm times 90 cm, or, for example, in an elongated rectangular manner with, for example, dimensions of 80 cm times 120 cm or 5 ft times 8 ft, with respect to a layout, wherein room side walls 28 are formed, which delimit the room 2 in the circumferential direction, starting at the room floor 26 in orthogonal alignment to the latter. Here, the layout is square, for example, with side lengths d of 90 cm.
In the case of a usual rectangular design of the room 2, four room side walls 28 thus result, wherein two consecutive room side walls 28 in the circumferential direction can enclose essentially a 90 degree angle to one another based on a layout.
In the case of a formation of the room 2 in a corner area of a building, two of the room side walls 28 can be formed directly by means of the building walls delimiting the room 2. The further room side walls 28 lead into the floor plane 27 of the room, for example in order to provide for an access to a shower cubicle or the like there.
In the case of showers, which are arranged, for example, in room niches, three room side walls 28 arranged consecutively in the circumferential direction can be formed directly by means of room walls of the building, while a fourth room side wall 28 leads freely into the floor plane 27 as access to the shower.
Regardless of the above-described concrete arrangement and formation, the room 2 usually serves the purpose of receiving a tub, in particular for example a shower tub, for the further preferred formation in particular for example of a so-called floor-level shower.
A free end of a pipe 29, in particular of a drainage pipe for waste water, usually protrudes into the room 2. The pipe 29 can, and as preferred, be arranged so as to lie on the room floor 26. A pipe opening in particular pointing to the top is aligned and correspondingly positioned for the connection to a drainage opening provided in the tub.
The side parts 5, 6, 7, 8 of the lining unit 1 have—as mentioned above—different heights a, b. Here, the second side parts 7, 8 have, for example, a second height b of approx. 5 cm, while the first side parts 5, 6 covering a wall of the illustrated shower up to the upper tile rim 30 have, for example, a first height a of 200 cm. The long side parts 5, 6 of the lining unit 1 are thus approximately 40 times as high as the short side parts 7, 8. The height of the first side parts 7, 8 additionally corresponds to the height of the tiled backsplash, which usually ends approximately 30 cm above the position of a shower head or completely reaches up to the room celling 31.
The lining unit 1 is already pre-assembled by the manufacturer to the standard size of the floor of the room 2 of, for example, 90 cm×90 cm and is equipped with a bottom part 4 and side parts 5, 6, 7, 8 of the required heights a, b and side lengths d—for example on the basis of a dataset transmitted by the end customer or assembler.
Here, the bottom part 4 of the lining unit 1 has four corners 9 with an angle of, for example, 90 degrees each. Corners with angles of 90 degrees each are accordingly also located between the adjacent side parts 5, 6, 7, 8 of the lining unit 1.
As illustrated in particular in
As shown in the detail illustration of
The rim areas 11, 12, which are adhered to one another or welded to one another, are subsequently jointly folded over to one of the two side parts 5, 6 of the lining unit 1, here the side part 6, until the rim area 12 of the side part 6 abuts against the adjacent subarea of the same side part 6 from the outside (see
Finally, the three-layered side seam 10 is adhered or welded once again according to
Alternatively to the described approach with the consecutive operating steps welding and folding over, a folding over of the rim areas 11, 12, which are placed one on top of the other, can initially also take place and a welding only thereafter, in particular a welding of the rim areas 11, 12 to one another as well as a welding of the rim areas 11, 12 to the outer side of the side surface 6.
By means of the welding process, which is carried out here, for example, a welded side seam 10 with a tangible and visible depression 23 and depression rim edges 24 surrounding the depression results—as illustrated in
A seamless transition preferably exists between the subareas 16 and 17 of the insertion part 14 by means of merely folding over the film material of the lining unit 1.
For the formation of the bottom seam 18, adjacent rim areas 20, 21 of the subareas 16, 19 of the bottom part 4 are placed one on top of the other and are connected to one another. The connection can in particular be created by means of adhering or welding.
Even though this is not illustrated here, the insertion part 14 can generally also provide one or several complete side parts 5, 6, 7, 8 of the lining unit 1 and not only one or several subareas thereof. In this case, the bottom part 4 also does not merge seamlessly into the adjacent side part 5, 6, 7, 8 in the area of the insertion part but initially adjoins the insertion part 14, which then provides the seamless transition into the side part 5, 6, 7, 8.
For the formation of the outer corner, the insertion part 14 has an extension, which is essentially L-shaped here, wherein the legs of the L shape, which are angled towards each other, can each be placed against a room side wall 28 of the room 2 as part of the side part 5, 6 of the insertion part 14. The adjacent side parts 5, 6 of the insertion part 14 thereby merge seamlessly, namely in one piece, so that no seam is created on the corner 9 of the lining unit 1 formed therewith.
In contrast, side seams 10 are formed on the side parts 5, 6 of the lining unit 1 spaced apart from the corner 9, namely where the insertion part 14 transitions into the adjacent side part 5, 6.
Here, the bottom seam 18 is formed, for example, in several pieces or the bottom part 4 has several bottom seams 18 here, respectively, which are oriented transversely to one another. A first bottom seam 18 is formed parallel to the adjacent side part 5 of the lining unit 1, while a second bottom seam 18 lies at a 90 degree angle thereto and runs parallel to the adjacent side part 6 of the lining unit 1. The bottom seams 18 furthermore run transversely to the side seams 10, which connect the adjacent subareas of the side parts 5, 6 to one another. A respective point of intersection S between the bottom seam 18 and the side seam 10 is formed spaced apart from the respective corner 9 of the lining unit 1, so that neither the bottom seam 18 nor the side seam 10 lie on the corner 9 of the lining unit 1.
By interpositioning of the one-piece lining unit 1 illustrated in
Prior to the assembly of the lining unit 1 in the room 2, which is suggested purely schematically and in an exemplary manner in
According to
Two adjacent side parts 6′, 6″ are connected to one another via the outer corner 15. This can preferably take place via an insertion part 14 of the bottom part 4, as it has already been described with respect to
In addition to the side parts 6′, 6″, the lining unit 1 has further side parts 5, 6, 7, 7′, 7″, 8. With their respective adjacent side parts 5, 6, 6′, 6″, 7, 7″, 8, these side parts 5, 6, 7, 7′, 7″, 8 are each connected via 90 degrees corner 9. The corners 9 preferably each have a side seam 10 (see, for example, the side seam 10 according to
Here, the side parts 7 and 7″ are not connected, for example, via a corner 9 or outer corner 15, to the side part 7″ located between them but in a straight line. The middle side part 7′ is assigned to the area of the door opening 36 of the room 2 and can be formed, for example, as an opening side part with a small height of several millimeters up to a few centimeters, in order to seal a height difference between the room floor 26 of the room 2 and a room floor of an adjacent room connecting to the room 2 via the door opening 36.
Here, the side parts 5, 6, 6′, 6″, 7 and 7″ are formed, for example, to be of identical height, for example with a first height a, which corresponds to the height of the room 2 or of the room side walls 28 thereof, respectively.
Here, the side part 8 is formed in an exemplary manner so that it has a cutout for the window 37 of the room 2. The position and shape of the cutout thereby corresponds to the position and shape of the window 37, wherein the side part 8 adjoins the circumferential contour of the window 37 here, for example from two sides. The subarea of the side part 8 of the lining unit 1 lying between the window 37 and the bottom part 4 has a second height b, which is smaller than the first height a of the room-high side parts 5, 6, 6′, 6″, 7 and 7″ of the lining unit 1. Here, the first height a is, for example, 2.40 meters and the second height b is, for example, 0.90 meters. Other ratios between the heights a, b are also possible.
The
The insertion part 14 can be part of the lining unit 1.
According to the illustration in
According to the schematic illustration in
For example, the plastically deformable strip 43 can be received in a film pocket 41 formed between the side parts 5 and 6, as it is further illustrated schematically in
Such a film pocket 41, as can further be seen from
Due to the plastically formed section 40, the lining element 1 can be adapted to the conditions on site, in particular on the corner areas between room side walls 28, as part of the installation, in that, by manual application of the section 40, this material section is systematically pushed into the corner area (arrows p), optionally while stretching, and a non-resilient, preferably holohedral and therefore technically tight connection of the lining unit 1 with the room side walls 28 can be attained.
The
A flat, technically tight abutment of the lining unit 1 against the facing surfaces, here the room side walls 28, can also be attained as a result of such a plastically deformable rim design.
