Lining unit used to line an assembly space and method for lining an assembly space with a lining unit

field of technology

The invention relates to a lining unit used to line an assembly space below a tub, such as a shower tray, based on a film layer which has a preform used for edging in the assembly space, wherein in an installed state a floor surface is essentially perpendicular to the floor surface extending side surfaces are formed, further one or more side surfaces in a sealing portion

pass over

The invention also relates to a method for lining an assembly space below a tub, such as a shower tray, with a lining unit based on a foil layer, which has a preform used to fit into the assembly space, with a floor surface and essentially vertical in an installed state Side surfaces running to the bottom surface are formed, with one or more side surfaces

Chen merge into a sealing section.

State of the art

Lining units of the type in question are used in particular for the underside sealing of a trough area, in particular for sealing against the unfinished floor and/or in the walls bounding the

Moisture penetrating the assembly room. In this context, solutions

known, in which the lining unit for adaptation to the assembly space is composed of individual foil elements bonded to one another by adhesive or by welding, such as foil strips, in particular foil layers forming the bottom surface, and possibly preformed corner formations from the foil material. In the installed state, the trough-like assembly space is preferably completely lined, in particular comprising a liquid-tight covering of the assembly space floor and its side surfaces, one or more side surfaces of the assembly space being formed by the space wall rising from the unfinished floor

can.

In this context, further preformed lining units are known, which can each be used in the manner of a sealing trough in the assembly space, wherein in the installed state, in addition to an overlap of the assembly space floor and the assembly space side surfaces, a circumferential sealing section projecting beyond the side surfaces is also formed, for the possible integration of the covering the assembly room

the film layer in a surrounding sealing plane.

[0005] In the area of the assembly room, provision is usually also to be made for the implementation of a drain pipe or the like. Such a drain pipe passes through the lining unit, for example in the area of the bottom surface or one of the side surfaces. In order to counteract a leak in such a breakthrough area, it is known to provide the area penetrated by the object, such as a drain pipe, with a sealing flange. The lining unit can also already be provided with a

net, grommet-like pipe bushing.

Summary of the Invention

[0006] In view of the prior art described above, the object of the invention is to further improve a lining unit and a method for lining an assembly space with the aid of a lining unit.

to design better.

According to a first idea of the invention, a possible solution to the problem is given in a lining unit, in which it is intended that the lining unit in an initial state is free of openings with regard to a pipe penetrating the bottom surface or a side surface in the installed state and including the or the sealing sections is formed in one piece and, as a result of a corresponding flexibility and foldability in a transport form, prior to installation, folded together in a packet or

can be rolled up according to a corresponding rollability.

With regard to the method, the object can be achieved according to a further idea of the invention in that the lining unit in an initial state is free of openings with regard to a pipe penetrating the bottom surface or a side surface in the installed state and including the sealing section or sections is integrally formed in one piece and that in order to form a pipe passage in a bottom surface or a side surface, the film layer forming the lining unit is severed at the point intended for the pipe, with the extent of the separation being smaller than that which corresponds to the diameter of the pipe to be passed through, and that the lining unit is cut by means of the section is pulled over the tube, with elastic expansion of the section, so that a sealing is directly through the film layer

connection results.

[0009] As a result of the proposed embodiment, a lining unit that is favorable in terms of production and handling is created for lining an assembly space on the basis of a film layer. The lining unit is preferably designed in one piece both with regard to the bottom surface together with the side surfaces running essentially perpendicularly to the bottom surface in the installed state and the sealing sections adjoining the side surfaces. Accordingly, in the installed state, due to the preformed film layer forming the lining unit, there are no transitions to be produced separately at the installation site in the form of, for example, adhesive or welded transitions with respect to the lining unit. Rather, the result is a one-piece design from the bottom surface to the outside

via the side surfaces into the sealing sections.

[0010] Such a preformed, one-piece lining unit can be produced inexpensively, for example by deep-drawing in the case of a possible integral one-piece design. The installation of such a preformed lining unit also proves advantageous. There are no further sealing measures such as gluing or sealing in the immediate area of the assembly room.

welding required.

Even the sealing of an object guided through the bottom surface or a side surface, e.g. a pipe, can be carried out in a technically simple manner using the proposed lining unit, in that the flexible, resilient material for forming the film layer is used directly as a kind of sealing sleeve to rest against the pipe or the like is used. For this purpose, the foil layer, on which the lining unit is produced, is severed in the area of the penetration to be made, so that an incision or a recess is made in the foil layer

results in a shorter length (in the case of an incision) or a smaller one

Diameter (with a recess) than it corresponds to the outer diameter of the object to be carried out, for example the pipe. With penetration of the pipe, an elastic widening of the film material results in such a way that the film material can cling to the outer surface of the pipe like a spout, at least towards the recess made in the incision like a lip. Correspondingly, the film material of the lining unit that surrounds the pipe that passes through is used at the same time as a grommet or sealing sleeve. There is no need for any additional arrangement of sleeves or sleeves to be provided separately, with the further advantageous way being that the bottom surface or a side surface can be severed freely on site in the course of lining the assembly space and installing the preformed lining unit, depending on the arrangement of the pipe in the area of the assembly space . It is a universal, locally flexible arrangement of the proposed

molded lining unit allows.

[0012] The proposed starting state of the lining unit, folded or rolled up like a packet, is also advantageous in terms of handling, but also in terms of packaging and transport. The selected material thickness of the film layer, which with respect to a vertical cross section in the installed state over the bottom surface, the side surfaces and the sealing sections preferably remains the same, but can alternatively also be selected differently - for example lower material thickness in the area of the sealing section - allows folding or rolling into one handy package too. For example, as is also preferred, a film thickness in the range of a few tenths of a millimeter, for example 0.1 mm or also 0.25 mm, up to, for example, 2 mm is provided. In the package-like folded

th state of the lining unit, for example. Preformed corner areas

folded. Sections of the side surfaces and/or the sealing sections can lie on top of one another in layers together with regions of the bottom surface. In this case, for example, transition areas between the bottom surface and the side surfaces or between the side surfaces and the sealing sections can be used to form fold lines. Due to the selected very low material thickness of the lining unit as a whole, in particular of the foil layer, a bend or fold in a surface section of the bottom surface and/or the side surfaces and/or the sealing sections is also possible.

The handy lining package, which has significantly lower dimensions than the dimensions of the lining unit resulting in the installed state, for example with about 0.5 times or less up to, for example, up to 0.2 times the installation dimensions corresponding package - Extension dimensions, is unfolded or unrolled by the user at the installation site and placed directly into the assembly space with preferred direct or indirect contact with the assembly space floor and the assembly space side walls, with the preferred sealing sections adjoining the side walls on the peripheral boundary of the assembly space

area can be arranged overlapping.

[0014] The lining package can also be rolled up. A roll core, which preferably does not belong to the product itself, can also be provided here. It can be a roll core made of, for example, plastic or cellulose such as, for example, cardboard. The rolling core can be cylindrical. Also, a rolling up of the liner pack around itself, ie

without inserting a roll core.

7 144

Thus, a lining package with a structural dimension of, for example, 900 x 900 mm can be rolled up into a roll with a length of 900 mm and a diameter of about 90 mm. There can be a relationship

ratio of packing to unpacking of, for example, 1:5 to 1:10.

Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 1 and/or the further independent claim or with features of further claims. However, they can also be assigned to only individual features of claim 1 and/or the further independent claim or the respective further claim or respectively

be independent of importance.

[0017] According to a further development of the subject matter of the invention, the film layer can be designed such that it can be welded or glued. Accordingly, the film layer is preferably formed from a thermoplastic material which, for example, allows ultrasonic welding. Such welding or gluing can, for example, take place after the assembly space has been lined with the preformed lining unit between the film layer or the sealing section or sections and a subsequent sealing

level.

[0018] A further favorable adaptability of the lining unit to the assembly space can also be provided by a preferred stretchable configuration of the film layer. In particular, due to the selected material thickness of a few tenths of a millimeter, the layer can be flexible like a film at the same time, with the film layer also being able to stretch, with a

a measure of elongation at break of, for example, 50% to 1000%.

The film layer can be made of a flexible plastic material such as TPE or FPO. FPO is generally understood to mean an alloy of flexible polyolefins, in particular thermoplastic elastomers. For example, this can be HDPE, FPO, LDPE and thermoplastic elastomers such as SBS or SEBS. In addition, the

Film layer can also be designed as a PU film (polyurethane film).

[0020] The film layer can also consist entirely or partly of a plastic recyclate, but also partly or entirely of a bio-based plastic. Next, a film layer from a

foamed, preferably closed-pore, plastic.

[0021] The sealing section or also a transition area between a side face and the adjoining sealing section can also be designed with an integrated cut protection. Such cut protection can be a layer connected (e.g. glued or welded) to the film layer, further consisting, for example, of an aramide fabric. Such a cut-protection area can also be integrated directly into the film layer, so that--with reference to a cross-section through the cut-protection area--the cut-protection layer--e.g. the aramid fabric--of

the plastic forming the entire film layer can be covered.

[0022] The sealing section can be formed circumferentially in the installed state, in each case starting from the end region of the associated side surface facing away from the bottom surface. Depending on the installation situation and design of the installation space, the sealing section can extend approximately in a parallel orientation to the bottom surface of the lining unit or also in an extended orientation to the associated side surface. Also the

Transitions between the sections assigned to the respective side surfaces

The sealing sections (corner areas) are preferably formed in a closed manner, so that an integral, one-piece sealing section is formed all the way around, with a facing outwards, or when the sealing section is arranged on a wall

top, directed, circumferentially closed outer edge.

[0023] In order to improve the adhesion of the sealing section when it overlaps with a surrounding surface seal, the sealing section can have a surface treatment. In a known manner, a fleece, for example adhesively bonded to the sealing section, can be provided for this purpose, for example, on the top and/or underside of the sealing section. Advantageously, however, a surface treatment by siliconization (e.g. spray siliconization) can also be provided in this regard, further alternatively by a plasma treatment or

Corona plasma treatment.

The severing of the lining unit, in particular the film layer in the area of the bottom surface or in the area of a side surface for the passage of a pipe, for example, can be carried out according to a further preferred embodiment by punching or cutting out a flat piece from the lining unit. For this purpose, hole punches or circle cutters can be used in the usual way, by means of which a preferably circular hole with a reduced diameter compared to the outer diameter of the penetrating pipe can be punched or cut out on site in the course of the lining of the assembly space. The punching diameter can be about 0.9 to about 0.3 times the diameter of the pipe, so that the corresponding elastic expansion of the film layer in the area of the hole edge created when the film is pulled over the pipe results in a tight fit of the pipe

The edge of the hole on the pipe wall results.

Alternatively, the liner unit can also be severed by cutting into the liner unit. For example, with a blade, a straight cut with a length that is less than the outer diameter of the pipe can be made to prepare a

Nes passage area are made in the lining unit.

[0026] The severing can also be carried out by cutting the lining unit crosswise. For example, two cuts of essentially the same length can be made crosswise in order to prepare the surface piece for the tube to pass through. In addition, more than two intersecting cuts can also be made in order to prepare angularly smaller foil flaps based on a circumference that results in the slip-on and sealing situation, which is a favorable one

Plant and thus result in a cheap lip-like seal.

[0027] With regard to the method, it can also be provided that the lining unit can be present in a transport form prior to installation due to a corresponding flexibility and foldability, in which it is packaged

is folded up.

In a further possible embodiment, one or more further cuts can also be made in the film layer, in particular in the bottom surface and/or in one or more side surfaces, in addition to the cut for the pipe, for example for the sealed passage of a moisture suction duct or from electrical lines. In addition, revision penetration can also occur in this form

be seen.

[0029] In the area of the bottom surface and/or one or more

rer side surfaces a device for moisture monitoring and / or

-ad be provided. For example, a moisture sensor or an electronic camera can be arranged for this purpose, via which a display of

also reached in the area of the film layer accumulated moisture

can be.

[0030] In particular, the bottom surface, but optionally also a side surface, can additionally or alternatively have an absorber layer. A fleece or a substance can be applied to the film surface, which contains an absorbing agent such as, for example, a super absorber, which keeps any liquid that may occur in bound form and gradually

returns.

In addition, the film layer can be adjusted to prevent

Mold, e.g. due to a coating with an antifungal agent.

[0032] The thickness of the film can also be approximately 0.25 mm throughout, for example. The sealing sections can be provided with a double-sided butyl on the underside in order to self-adhesively to the overlapping area

carry out adjacent room sealing.

A reinforced butyl tape can be applied upwards in the area of the sealing sections, possibly only in individual sealing sections, so that a liquid seal or, for example, liquid tile adhesive can also be used in these areas. The reinforcement can be provided, for example, by an inserted, preferably coarse-meshed, fleece

be.

A sealing section can be mutually self-adhesive on the underside and reinforced with a fleece on the upper side. The reverse configuration is also possible, i.e. alternately self-adhesive on the upper side and reinforced with a fleece on the underside, and alternatively self-adhesive on both sides

or reinforced on both sides with fleece.

[0035] In this regard, configurations without any reinforcement are also possible, i.e. continuous films, which are then preferably made adhesion-friendly by additives or surface treatments, such as Corona-0-

plasma treatment.

[0036] In particular, the base area, optionally together with the side areas, can also be thicker than the sealing sections, for example to protect against damage. In this regard, thicknesses can be provided in the floor area that can correspond to 2 to 5 times the thickness in the area of the sealing sections (e.g. 0.5 to

1.25mm or 2.5mm).

[0037] To protect against damage, a protective fleece can alternatively

half of the floor area can be arranged loosely or glued on.

[0038] The ranges or value ranges or multiple ranges specified above and below also include all intermediate values, in particular in 1/10 steps of the respective dimension, thus possibly also dimensionless with regard to the disclosure. For example, the statement 50 to 1000% also includes the disclosure of 50.1 to 1000%, 50 to 999.9%, 50.1 to 999.9%, etc., the disclosure of 0.9 to 0.5 times , also the disclosure of 0.8 to 0.5 fold, 0.9 to 0.6 fold, 0.8 to 0.6 fold, etc. This disclosure may be one-

on the one hand to delimit a specified range limit from below and/or

Above, alternatively or additionally, but also for the disclosure of one or more

rer singular values from a given range.

Description of the embodiments

Is shown and described, first with reference to Figure 1, a lining unit 1 based on a film layer, which for lining a

Mounting space 2 is formed.

According to the illustration, the assembly space 2 can result from a box-like depression in the floor 3 of a location. Furthermore, the assembly space 2 can have an assembly space floor 4, which preferably results from the unfinished floor, which is vertically downwards compared to the floor level E resulting from the surface of the floor 3.

sets runs (cf. e.g. also FIG. 6).

The assembly space 2 can, as shown, be rectangular, more preferably elongated rectangular or square, with reference to a floor plan, with assembly side walls 5 extending from the assembly space floor 4 in a perpendicular orientation thereto and extending in the circumferential direction the assembly space 2 limit. In a conventional rectangular configuration of the assembly space 2, there are four assembly space side walls 5, with two side walls 5 following one another in the circumferential direction being able to enclose a substantially 90° angle to one another in plan view.

to.

In an embodiment of the mounting space 2 in a corner of

Location can, as shown by the arrangement in Figures 1 to 9,

two of the assembly room side walls 5 can be formed directly by the room walls 6 delimiting the assembly room 2 . The other assembly room

Side walls 5 open into the floor level E.

In a niche arrangement as shown in FIG. 10, three assembly space side walls 5 following one another in the circumferential direction are directly formed by space walls 6, while the fourth assembly space side wall

wall 5 opens freely into the floor level E.

The assembly space 2 can also be designed in which only one assembly space side wall 5 is formed by a space wall 6 (cf. FIG. 11). The other ones following one another in the circumferential direction

Assembly room side walls 5 end here in the floor level E.

FIG. 12 shows a further possible embodiment of an assembly space 2, in which all assembly space side walls 5 open freely into the floor level E. The assembly room 2 is accordingly at a distance from the - not here

shown - room walls 6 positioned.

The assembly space 2 is used, regardless of the specific arrangement and design described above, for accommodating a tub 7, for example a shower tub, for the more preferred design of a so-called

th floor-level shower tray (see detail view in Figure 8).

A free end of a pipe 8 , in particular a drain pipe suitable for the trough 7 , usually protrudes into the assembly space 2 . The tube 8 can, as is also preferred, be arranged lying on the assembly room floor 4

be. The pipe opening 9 pointing upwards, as can be seen, for example, in FIG

designed for connection to a drain opening provided in the tub 7

tet and placed according to the positioning of the tub drain opening.

The lining unit 1 provided for the sealing lining of the assembly space 2 is preferably three-dimensionally preformed and integrally formed in one piece. The foil layer on which the lining unit 1 is based is, in particular, a plastic foil, for example a polyurethane foil, which can also be formed into a shape adapted to the extent and depth of the assembly space 2 in a deep-drawing process, for example

can be spent or manufactured.

The lining unit 1 initially has a bottom surface 10

with extension dimensions a' and b' adapted to the length a and the width b of the assembly room floor 4 viewed transversely thereto. The bottom surface 10 is in the illustrated embodiment corresponding to the surface extension

ckung the assembly room floor 4 elongated rectangular.

Perpendicular to the bottom surface 10 side surfaces 11 are formed over the entire circumference. These side surfaces 11 can be formed integrally in one piece and preferably of the same material as the bottom surface 10, it also being possible for the side surfaces 11 to be formed integrally in one piece with one another in the respective resulting corner regions. The design of the side surfaces 11 with a height c' that is the same over the circumference of the base surface 10, which height c' is adapted to the height c of the assembly space side walls 5, results in an overall one-piece and completely closed box-like shape of the lining unit 1. One possible embodiment is an integral, one-piece design of the lining unit 1

before.

The side surfaces 11 facing away from the bottom surface 10 likewise preferably merge in one piece into sealing sections 12, 12'. The alignment of the sealing sections 12, 12' to the respective side surface 11 is preferably adapted to the structural situation, in particular to the placement of the assembly space 2. Thus - based on a cross section perpendicular to the surface extent of the base surface 10 - a sealing section 12 of a side surface 11 extends , which side surface 11 is assigned to a room wall 6 when the assembly space 2 is lined, preferably as an extension of the side surface 11 (cf. e.g. the representation in Figures 5 and 6), while a sealing section 12' of a side surface 11, which side surface 11 is in the lined state of the assembly space 2 is not assigned to a room wall, but rather to a free surface of the floor 3, in the aforementioned cross section essentially perpendicular to the extension of the assigned side surface 11 to the outside.

running.

Thus, according to the exemplary embodiment of the assembly space 2 shown in Figures 1 to 9 - corner arrangement with two space walls 6 - a preformed lining unit 1 can be provided with two sealing sections 12 following one another in the circumferential direction, each of which with reference to the above-described cross section in Substantially extend in extension to the associated side surface 11, and with two further sealing portions 12 ', which in the cross-section essentially at an angle of

about 90° angled outwards.

In a niche arrangement of the assembly space 2 according to Figure 10, the lining unit 1 is preferably due to corresponding manufacturing

prepared in such a way that three sealing seals following one another in the

Sections 12 are provided, which extend to the associated side faces 11 in the cross section. Only one side surface 11 goes over

into a sealing section 12' projecting outwards at right angles.

In a wall arrangement of the assembly space 2 according to FIG

associated side surface 11 extend outwards.

In relation to the floor 3 of the locality free, that is to room walls 6 spaced formation of the assembly space 2 according to Figure 12, there is a lining unit 1, which completely circumferential with

is provided according to preformed sealing sections 12 '.

The sealing sections 12 and 12′ or the sealing sections 12′ of the embodiment shown in FIG. 12 are also connected to one another in the resulting corner regions 13 viewed in the circumferential direction, preferably as a result of one-piece, more preferably integrally one-piece

design.

The thickness d of the plastic film 14 can be chosen to be the same, as is also preferred, especially in the area of the bottom surface 10 and in the area of the side surfaces 11, moreover more preferably also in the area of the sealing sections 12 or 12'. In an alternative embodiment, for example, in the area of the sealing sections 12 or 12', a thickness d that is reduced compared to the bottom surface 10 and/or the side surface 11 can be selected, for example for further improved integration of the sealing sections into a surrounding surface area.

seal in the area of the room walls 6 or the floor 3.

For each possible assembly space configuration (delimited by one, two or three space walls 6 or arranged freely in space according to FIG. 12), a lining unit 1 preformed at the factory during production with sealing sections 12 and sealing sections 12′ can be provided. In addition, the plastic film 14 of the lining unit 1 can also be adjusted so that it is stretchable so that the sealing sections 12 or 12′ in particular can be adapted to the structural conditions. For example, a preformed lining unit 1 for arrangement in an assembly space 2 according to the illustration in FIG. by pivoting a sealing section 12' into a vertical position, essentially into a position representing an extension of the associated side surface 11 in cross section, for arranging the lining unit 1 in an assembly space 2 with a space wall 6, for example according to FIG

Figure 11 can be adjusted.

For economical transport and, if necessary, for accommodation in a space-saving packaging, the lining unit 1 can initially be present folded up in the form of a packet as shown in FIG. The lining unit 1 can also be in the form of a roll. For example, the sealing sections 12 or 12 ′ can first be folded inwards, if necessary up to a position in which they come into contact approximately with the inwardly pointing surface of the associated side surfaces 11 . These side surfaces 11 can also be placed further, for example, possibly together with the sealing sections 12 or 12 ′ in the direction of the facing surface of the bottom surface 10 . By further turning over the already pre-folded film package along fold lines running in width b' and/or length a' into a transport form 15

a package of foil layers can be created, the dimensions of which (length a" and

Width b"), for example, approximately 0.5 times or less, further, for example, approximately 0.3 times the length a' and width b' in the unfolded state of the lining

may correspond to unit 1.

On site, at the installation site, the transport form 15 of the lining unit 1 is unfolded into the space provided for lining the assembly space 2.

he form.

To compensate for any unevenness and/or to protect the film layer 1, a optionally separately provided fleece layer 16 can, as is also preferred, first be inserted into the assembly space 2 (see FIG. 2). This fleece layer 16 can, as further preferred, be adapted in terms of area to the extension of the

Assembly room floor 4 are adjusted.

In order to form a pipe passage through the fleece layer 16, the fleece layer 16 is cut in accordance with the positioning of the pipe 8 or its pipe openings 9 using a tool, for example a knife 17. A cross cut 18 is shown in FIG. 2. The pipe 8 can pass through the area severed in this way when the nonwoven layer 16 lies essentially over the entire surface of the assembly room floor 4 (cf. FIG. 3).

For the passage of the pipe 8 through the lining unit 1, which is otherwise completely closed overall, this must also be prepared before the lining unit 1 is introduced into the assembly space 2. For this purpose, depending on the positioning of the tube 8 or the tube opening 9 in the bottom surface 10, if necessary alternatively with a corresponding lateral arrangement of the tube 8 in the area of one of the side surfaces 11, a severing, in particular of the plastic film 14 of the lining unit 1,

performed,

Such a severing 22 can be achieved, for example, by cutting the plastic film 14 using a knife or a circle cutter. Shown is the use of a hole punching tool 19, which is correspondingly positioned on the floor surface 10 in the exemplary embodiment according to FIG. In this process, particular preference is given to the bottom surface

surface 10 is backed by a resistance, e.g.

here from the bottom surface 10 is punched out (see FIG. 4).

As a result of such a punching out, a severing 22 with a circular severing edge 23 results 8, in which the lining unit 1 rests sealingly with its plastic film 14 in the lining position. Thus, the dimension e' of the severing 22 corresponds, for example, to about 0.9 times or less, further, for example, to 0.7 to 0.5 times up to 0.3 times the predetermined

written outer diameter e (see also Figures 6 and 7).

In the course of arranging the unfolded lining unit 1 in the assembly space 2, the area with the cut-through 22--in the illustrations the corresponding area in the bottom surface 10--is put over the free end of the pipe 8, which has the pipe opening 9, with elastic expansion the severance 22 corresponding to the pipe outside diameter e. If necessary, after slipping over a bead 24 of the pipe 8 that is larger in diameter than the general pipe diameter e, the plastic film 14 of the lining unit 1 lies along the severing edge 23 due to the elastically resilient design of the plastic film 14

lip-like sealing on the circumferential outer wall surface of the raw

res 8 (compare Figures 6 and 7).

Advantageously, only the elastically resilient properties of the plastic film 14 used are used to form the sealed opening for the pipe 8. The area of the plastic film 14 surrounding the cut 22 nestles in a grommet-like seal

on the facing surface of the tube 8 at.

In the lining position, for example according to FIG. The side surfaces 11 can, as is also preferred,

directly against the facing assembly room side walls 5.

In one possible embodiment, the separate fleece layer 16 described above can also be attached to the underside of the bottom surface 11 on the plastic film 14

e.g. be laminated on.

The upright sealing sections 12 protrude perpendicularly beyond the floor plane E and, in the final use position, are embedded in a sealing slurry 25 applied to the room wall 6 in this area to integrate the lining unit 1 into the surrounding seal. The sealing section 12 ′, which protrudes outwards at an angle essentially at right angles to the associated side surfaces 11 , also rests in the final use position on the floor 3 surrounding the assembly space 2 in a form formed, for example, by an applied sealing slurry 25

Embedded sealing level (see FIG. 6).

To improve adhesion between the sealing section 12, 12 'and the wall or. sealing slurry 25 on the bottom side, the sealing sections 12, 12' can be set to improve adhesion accordingly. This can be achieved by surface treatment, for example by siliconization or by plasma or corona treatment. On the other hand, an embodiment is shown in which the sealing sections 12, 12' are provided with an adhesive fleece 26 on both sides (cf. enlarged illustration in FIG. 8). Such an adhesive fleece 26 can

be laminated in the course of manufacturing the lining unit 1.

In addition, to further improve handling when lining the assembly space 2 with the preformed lining unit 1, an adhesive strip 27, e.g. a butyl adhesive strip, can be arranged, by means of which after removal of a cover film 28 a first adhesion of the sealing sections 12 and 12 ′ can take place on the facing surfaces of the room walls 6 and/or the floor 3 . Such an adhesive strip 27 can, as shown, be arranged on the foot side of the respective sealing section 12, 12′, such that when the sealing section 12 protrudes upright as an extension of the side surface 11, the adhesive strip 27 preferably extends directly above the floor plane E. In the case of a sealing section 12' extending essentially in a horizontal plane, the adhesive strip 27 can be arranged in such a way that in the arrangement position it extends essentially and preferably directly along the edge

edge of the mounting space 2 to the floor 3 extends. [0074] In addition, a sealing section 12, 12' or a plurality

number up to all sealing sections facing the resulting in the installed state

end room side have an integrated cut protection 29. It can

be, for example, an aramid layer which is permanently connected to the area of the sealing section 12, 12', for example adhesively bonded or welded. This cut protection 29 is preferably in a transition area between

's side surface 11 and associated sealing portion 12, 12 'positioned.

In the usual position of use of the tub 7, the room wall 6 delimiting the tub area and the surrounding floor 3 are provided with a wall or floor covering in the usual way. As shown in FIG. 8, tiles 31 can be provided, which are fastened directly to the room wall 6 or in the lower end area facing the tub 7 by means of tile adhesive 32, covering the associated sealing section 12. The distance left between a lower edge of the tile and the edge of the trough 7 is bridged in the usual way, for example with silicone 33 . Is a removal of the silicon

kons 33 necessary, this can be done or prepared by cutting with a knife. The cut protection 29 described above prevents the plastic film 14 of the lining unit 1 from being damaged when a knife is used and thus the desired tightness in the area of the assembly

room 2 is canceled if necessary.

Alternatively or in combination with the cut protection 29, a soundproofing strip 30, preferably made of a foam material, can be provided on one or more sealing sections 12, 12', against which the edge of the tub steps when the tub 7 is in the closed installation position (cf.

Figure 8).

The soundproofing strip 30, which is preferably made of a suitable foam material, can, like the possible cut protection 29, have the adhesive

fleece 26 and the adhesive strip 27 are part of the package or roll-ar-

tig present lining unit 1, the initially completely closed plastic film 14 for forming the bottom surface 10, the side surfaces 11 and the sealing sections 12, 12 'in one piece, optionally integrally formed in one piece.
