FLOOR CONSTRUCTION OF A SHOWER

Description

[0001] The present invention relates to a floor structure of a shower according to the preamble of claim 1.

[0002] Typical floor constructions for showers are known in numerous variations from the prior art, for example from DE 20 2010 003 239 U1. The floor constructions of such showers usually consist of one or more sloping wedges or a screed and a drain for conveying shower water into a drainage pipe.

[0003] Especially in the case of slope wedges on which tiles or slabs are laid, the tiles or slabs of the shower floor must always be laid in such a way that they slope towards the drain.

[0004] The use of foamed panels to create the required slope or the installation of a sloping screed is also known, but this involves considerable effort.

[0005] It is also known to lay tiles with a slope towards a channel-like drain. Due to the resulting gaps perpendicular to the slope, the use of profile systems is necessary in this case, the installation of which can also be quite complex.

[0006] Another problem is the watertightness of the shower floor, especially in the transition area to the sealing layer of the floor surface in the room where the shower is installed, as well as in the transition area to sealing layers of adjoining walls, which are often also tiled.

[0007] To achieve the required seal, sealing tapes and three-dimensional sealing corners are integrated in the transition areas, connecting to the sealing surfaces of the floor and walls. These sealing tapes and sealing corners must be adhesively attached over a minimum width, although the necessary adhesive surfaces are often not predefined.

[0008] The joints between floor slabs and adjoining wall surfaces (tiles, natural stones, etc.) are sealed with permanently elastic jointing material.

[0009] However, such permanently elastic jointing material does not constitute a permanent seal, so that if such a joint is damaged, there is always a risk of water entering the building structure behind and beside the floor construction of the shower.

[0010] When renewing the permanently elastic seal, there is also a risk of damaging the seal. To prevent this, a cut-resistant strip is usually laid in front of the sealing tape, which further increases the effort required to install the shower floor structure.

[0011] Both channels and centrally located drains are used to drain the surfaces of the shower that come into contact with water during use. Cleaning the channels is extremely laborious if the water flows beneath a channel cover along its entire length.

[0012] US Patent 5,371,980 A discloses a shower tray with folded connecting edges of the frame walls running around the perimeter of the shower tray for the purpose of gripping a wall covering adjoining the base frame.

[0013] The object of the present invention is to provide a floor structure for a shower that ensures a permanent seal, can be installed with less assembly effort and allows sealing work to be carried out in a simple manner.

[0014] This problem is solved by a floor construction of a shower with the features of claim 1.

[0015] The floor structure of a shower according to the invention comprises at least one slope wedge, one drain and one floor frame.

[0016] The base frame is designed as a tub with a supporting base and frame walls that are folded upwards at the edges.

[0017] In this process, the connecting edges of the frame walls furthest from the supporting floor are folded over to allow for the rear engagement of a wall cladding that at least partially adjoins the floor frame or for the under-engagement of a floor covering that at least partially adjoins the floor frame.

[0018] The connecting edge of a frame wall to the underside of a seal adjoining the floor frame, as well as a floor covering and its bedding, extends parallel to the supporting floor, offset to the outside.

[0019] This type of shower floor construction ensures a watertight seal, particularly in the critical transition areas between the shower and the wall covering or flooring. All water is channeled into the tray-like floor structure and from there via the drain into the sewer line.

[0020] Advantageous embodiments of the invention are the subject of the dependent claims.

[0021] According to an advantageous embodiment, the side edges of the frame walls are bonded together in the corner areas of the base frame, in particular by welding. A bonded connection of these side edges ensures a permanently watertight seal between them.

[0022] Furthermore, this allows for the simple manufacture of the base frame from a sheet of metal, which only needs to be cut at the corners. The resulting sections are then folded over and subsequently welded together to create the tub-like base frame.

[0023] According to another advantageous embodiment, the connecting edge of a frame wall extends vertically to the supporting floor for the rear grip of a wall cladding adjoining the base frame.

[0024] This connecting edge extends behind the sealant and, for example, the tile backsplash used as wall cladding, so that water running off the wall drains into the floor frame designed as a tub and not into an area between the shower floor and the wall.

[0025] The height of the connection edge is preferably defined to accommodate a sealing tape.

[0026] According to a preferred embodiment, the frame wall is stepped to allow for the engagement of a wall cladding adjoining the base frame, with the connecting edge being offset outwards parallel to a section of the frame wall adjoining the supporting base.

[0027] The width of the connection edge is preferably defined to accommodate a sealing tape.

[0028] In another design variation, a section of the frame wall, perpendicular to the supporting floor, is bent into a U-shape towards the connection edge. This U-shaped bend creates a watertight seal between the shower and the floor covering. A subsequent further bend then connects the frame wall to the floor covering and its bedding.

[0029] According to another embodiment, the upper side of at least one slope wedge, facing away from the support base, is shaped with a slope towards the drain.

[0030] This allows for the installation of a floor covering, such as tiles, on at least one sloping wedge without having to create a slope separately when laying the tiles. Furthermore, the floor frame eliminates the need for any sealing work to prevent water from penetrating into areas outside the shower floor.

[0031] According to one design variant, the gradient wedge leads to a recess opening into the drain, which is provided, for example, with a cover in the form of a slot or a bore.

[0032] According to another design variant, the slope wedge has a recess in which a channel is accommodated.

[0033] If the slope wedge is designed with a slope in one direction, the channel can be positioned adjacent to a wall.

[0034] In an alternative design variant, two slope wedges are embedded in the base frame, between which the drain channel is accommodated.

[0035] This also makes it possible to position such a channel and drain in a central area of ​​the floor. The slope wedges are each oriented with a gradient towards the channel.

[0036] It is conceivable to provide two wedges of equal size.

[0037] According to an alternative design variant, the two slope wedges are of different sizes, so that different positioning of the channel or the drain is possible.

[0038] To prevent standing water in the channel, the channel has at least one gradient wedge, the surface of which, facing away from the supporting ground, is inclined towards a drainage chamber of the channel.

[0039] According to a preferred embodiment, two such gradient wedges are incorporated in the channel, which allows the drainage chamber of the channel to be positioned at different locations in the channel.

[0040] According to another preferred embodiment, the drainage chamber of the channel is covered with a sieve and by a drainage cover provided with a drainage opening.

[0041] According to another design variant, a mounting element with a recess for a trap and a pipe section connected to the trap is arranged below the support base. This allows for easy connection to a drain pipe and leak testing of the drain from the outside.

[0042] According to another design variant, the support base has a spigot attached to its underside facing the superstructure element, onto which the odor trap can be attached.

[0043] According to another alternative design variant, the drain has at least one channel with at least one drainage surface inclined towards a drainage chamber of the drain. In this design variant, the drainage surface already forms the visible surface of the drain, which lies flush with or slightly below the level of the surrounding floor covering of the shower floor.

[0044] The channel preferably has two drainage surfaces inclined towards a fold extending in the direction of the drain's longitudinal axis. This ensures that puddles cannot form in the channel area and that all water flows quickly towards the drain's outlet chamber.

Fig. 28 shown floor along the drain, and Fig. 32 a sectional view of the in Fig. 28 The floor shown is perpendicular to the drain.

[0046] In the following figure descriptions, terms such as top, bottom, left, right, front, back, etc., refer exclusively to the exemplary representation and position of the floor, slope wedge, drain, floor frame, and the like in the respective figures. These terms are not to be understood restrictively; that is, these references may change due to different working positions, mirror-symmetrical layouts, or similar factors.

[0047] In the Figs. 1 to 8 Reference numeral 1 denotes a variant embodiment of a shower floor structure according to the invention. The floor structure 1 comprises at least one sloping wedge 2, 2a, 2b, a multi-part drain 3, and a floor frame 4, which, in the illustrated embodiments, accommodates the at least one sloping wedge 2, 2a, 2b.

[0048] In the Figures 1 to 4 , 7 and 8In the illustrated design variants, the floor structure 1 features two such slope wedges 2a, 2b, which are inserted into the floor frame 4 with a slope towards the drain 3. An exemplary exploded view of the [details omitted] is shown in the Figures 1 and 2 The version shown is in Figure 10 As shown, the two slope wedges 2a, 2b are of different sizes in the embodiment shown here due to the position of the drain 3. Slope wedges 2a, 2b of the same size are also conceivable, particularly if the drain 3 is located in the center of the tub.

[0049] During the Figures 5 and 6 In the illustrated version, the floor structure 1 has a single slope wedge 2, which is inserted into the floor frame 4 with a slope towards the drain 3 located at the edge of the floor frame 4.

[0050] The base frame 4 is, for example, in Fig. 9It is shown as a tub with a support base 41 and frame walls 42a, 42b folded over at the edges.

[0051] The frame walls 42a, 42b are formed integrally with the supporting base 41. In the case of a base frame 4 made of a metal sheet, the frame walls 42a, 42b are bent upwards relative to the usually horizontally oriented supporting base 41, thus forming a trough.

[0052] The connecting edges 43, 44 of the frame walls 42a, 42b, located away from the support base 41, are, as shown in particular in the Figs. 11 to 16 As can be seen in the detailed illustrations, the edge is folded over to reach behind a wall covering that at least partially adjoins the base frame 4 or to reach under a floor covering that at least partially adjoins the base frame 4 and the corresponding sealing levels.

[0053] Accordingly, the two connecting edges 43 of the in Fig. 4In the illustrated embodiment, the wall cladding adjoining the base frame 4 is bent so that it extends vertically to the support base 41 for the rear grip.

[0054] After the installation of the floor structure 1, these connecting edges 43 face the wall surface of the adjacent wall with their outer surface.

[0055] A tile or panel backsplash, which is later attached to the wall of the shower, covers these connecting edges 43, so that water running off the wall covering does not run into the area behind the floor structure 1, but into the area of ​​the floor frame 4 designed as a tub.

[0056] The frame wall 42a is preferably shaped in a stepped manner to allow for the rear engagement of a wall cladding adjoining the base frame 4, wherein the connecting edge 43 is offset outwards parallel to a partial area 46 of the frame wall 42a adjoining the supporting base 41.

[0057] Depending on the thickness of the tile or slab surface or alternative wall covering, the width of this step 47 can be easily adjusted during the manufacture of the floor frame 4.

[0058] It is also conceivable to form the frame wall 42a in a straight line, i.e. without such a step, for the rear grip of a wall cladding adjoining the base frame 4.

[0059] As in the Figs. 11 to 14 As further shown, the connecting edge 44 of a frame wall 42b extends outwards parallel to the supporting floor 41, offset from the underside of a floor covering adjoining the base frame 4. Depending on the thickness of the floor covering, the relative height at which the connecting edge 44 extends outwards can be easily adjusted.

[0060] During the Fig. 7, 8 , 15 and 16In the illustrated variant of a raised shower that is not flush with the floor but protrudes upwards above the floor, the connecting edge 44 of a frame wall 42b extends outwards to the underside of a floor covering adjoining the floor frame 4 at the same height as the supporting floor 41.

[0061] Preferably, a partial section 46 of the frame wall 42b adjoining the support base 41 perpendicularly is bent in a U-shape towards the connecting edge 44, so that the partial section 46 of the frame wall 42 adjoining the support base 41 serves as a boundary of the tub and a preferably vertically downward extending outer wall section 48 adjoins the partial section 46 via a horizontally extending upper visible edge 47, from which the connecting edge 44 then extends outwards at the level of the support base 41.

[0062] The connecting edges 44 serve to simplify the connection to a sealing layer of a floor covering in the room in which the shower is installed.

[0063] In addition to the representation shown here of the floor frame 4 with two frame walls 42a for connection to a wall covering and two frame walls 42b for connection to a floor covering, which is suitable for installing the floor 1 in a corner of the room, it is also conceivable, for example, to form only one such connecting edge 43 for the rear engagement of a wall covering adjoining the floor frame 4 and three frame walls 42b with connecting edges 44 for connection to the floor covering, whereby the floor assembly 1 in this case is suitable for installation on a wall of the room, away from a corner of the room.

[0064] It would also be conceivable to design the base frame 4 with four connecting edges 44 for connection to the floor covering, so that the floor structure 1 with a base frame 4 designed in this way is also suitable for installation spaced away from walls of the room, for example in the middle of the room.

[0065] It would also be conceivable to design the floor frame 4 with only one connecting edge 44 for connection to the floor covering and three frame walls 42a for connection to a wall covering, so that the floor structure 1 with a floor frame 4 designed in this way is also suitable for installation in a niche of the room.

[0066] The vertically (in direction z) or nearly vertically oriented side edges of the frame walls 42a, 42b in the corner areas of the base frame 4 are preferably bonded together, in particular welded together. They thus ensure permanent watertightness of the base frame 4, especially through the connection of sealing strips 7, which are explained in more detail below, and without the use of otherwise conventional three-dimensionally shaped sealing corners.

[0067] To prevent standing water in the area of ​​the floor structure 1, the upper side of the at least one slope wedge 2, 2a, 2b facing away from the supporting floor 41 is formed with a slope towards the drain 3.

[0068] In the exemplary embodiment according to the Figures 1 to 6The two slope wedges 2a, 2b are inserted within the base frame 4, which is designed as a trough, in such a way that the slope wedges 2a, 2b slope towards the drain 3 and thus onto the slope wedges 2a, 2b or onto tiles or slabs 8 arranged thereon, as exemplified in the Figures 25 to 27 shown, water that hits the outlet will flow towards outlet 3.

[0069] As in the Figure 9 , 21 and 22 As shown, the drain 3 further comprises a trap 35 and a drain spout 37 extending towards a superstructure element 5 arranged below the support base 41, onto which the trap 35 can be attached. The drain spout 37 is preferably bonded to the support base 41.

[0070] The assembly element 5 has a corresponding cutout 51 for receiving the odor trap 35 and a slot 52 for receiving a pipe section 38 for connection to a wastewater pipe. The pipe section 38 preferably extends to a side edge of the assembly element 5 or, as shown in the Figures 3 and 4 shown, extending beyond the side edge of the structural element 5.

[0071] The drain nozzle 37 passes through a drain opening 45 in the support base 41 of the base frame 4.

[0072] The channel 32 preferably consists of two separating webs arranged parallel to each other, between which one or more further gradient wedges 33 can be inserted, the surface of which, or whose surface facing away from the support base 41, is inclined towards the drainage chamber 36 or towards the drainage cover 31 of the support base 41.

[0073] It is also conceivable to design the channel as a U-shaped profile in cross-section with a drainage opening provided in the ground, into which the slope wedge 33 or the slope wedges 33 can be inserted.

[0074] The gully 32 shows in the Figures 1 to 10 In the exemplary embodiments shown, the length corresponds to the width (in direction x) of the support base 41. In the embodiments shown in the Figures 23 to 25 In the illustrated examples, the channel is significantly shorter.

[0075] A sieve is inserted above the drain opening 45 of the support base 41 and is fixed in a drain chamber 36 within the channel 32. The sieve 34 is covered at the top by a drain cover 31. A narrower channel 32 could also be used.

[0076] As in the Figures 1 to 8 and 10 Furthermore, as shown, two gradient wedges 33 are incorporated in the channel 32.

[0077] This allows the shower water to be directed, following the slope of the gradient wedges 2a, 2b, initially towards the channel 32 (as exemplified in Figure 22 (as shown) and can then flow over the gradient wedges 33 to the drainage chamber 36, which is centrally located in the channel 32, as exemplified in Figure 21 shown. Figure 20 shows the intersection lines of the in the Figure 21 and 22 Sectional views shown.

[0078] As in Fig. 3, 4 and 9 As further shown, a soundproofing panel 6 is preferably arranged below the assembly element 5. This panel can be attached to the base frame 4 and thus installed on-site as a complete unit in the room where the shower is to be installed. It is also conceivable to attach such a soundproofing panel 6 directly to the underside of the base frame 4 if the floor assembly 1 does not require an assembly element 5.

[0079] As in the characters Figs. 25 to 27As shown, slabs or tiles are placed on the slope wedges 2a, 2b, 33, forming the visible surface of the shower. These slabs or tiles can be easily placed on the slope wedges 2a, 2b and glued in place. However, other flooring materials that can be applied to the slope wedges are also conceivable.

[0080] While the plates 8 during the in Figure 26 In the illustrated version, which forms a stepless transition to the adjacent floor slabs, the slabs 8 are located in the Figure 27 In the illustrated version, a so-called splash guard 9 is positioned slightly deeper in the base frame 4. The depth of the base frame 4 can be easily adjusted to the desired laying method and slab thickness by varying the height of the section 46 of the base frame 4.

[0081] To seal the base frame 4 to the walls or floor of the room in which the shower is to be installed, the following are to be done as shown in Figure 17 As shown, sealing tapes 7 are preferably arranged at the connection edges 43, 44 of the frame walls 42a, 42b. The sealing tapes 7 are preferably bonded to the connection edges 43, 44 of the frame walls 42a, 42b. The sealing tapes 7 project beyond the surface of the connection edges 43, 44 for connection to the wall cladding or the floor covering and its bedding, wherein the width of the connection edges 43, 44 (perpendicular to their longitudinal extent) is dimensioned such that a sufficient bonding surface is available.

[0082] For better anchoring in the bedding of slabs or tiles, the connecting edges 43, 44 of the frame walls 42a, 42b are designed according to a specification in the Figures 18 and 19The illustrated version features perforated holes. The holes 49 in the connecting edges 43, 44 are designed as elongated holes in the illustrated version; however, other shapes for the holes 49 are also conceivable. It is also possible to perforate only sections of the connecting edges 43, 44.

[0083] Furthermore, the connecting edges 43 and 44 of the frame walls 42a and 42b serve as cut protection to prevent damage to a sealing tape located behind the permanently elastic jointing.

[0084] This permanently elastic joint is located above an area where standing water could occur, so that even if the sealing joint is damaged or missing, the water always flows into the base frame 4.

[0085] The slope wedges 2a, 2b and 33 preferably consist of extruded polystyrene foam plates. Other materials are also conceivable for the slope wedges 2a, 2b and 33.

[0086] It is also conceivable to arrange at least one slope wedge 2, 2a, 2b below the base frame 4. In this case, the supporting base 41 is shaped in such a way that it follows the shape of the slope wedges 2a, 2b, thus ensuring a flat bearing surface or support for the base frame 4.

[0087] In the Figures 28 to 32 Another alternative embodiment of a shower floor structure according to the invention is shown.

[0088] Unlike the one in the Figures 1 to 8 In the illustrated version, the drain 300 is not designed with slope wedges 33, but rather as a channel component adjoining the tile layer on the slope wedges 2a, 2b.

[0089] This gutter component, as shown in the Figures 28 to 30The figure also shows a drain cover 310 with a slot 311, which in the embodiment shown here is arranged centrally between two channels 320 extending in the longitudinal direction of the drain 300.

[0090] The 320 channels are designed according to a Figure 28 The illustrated version is slightly inclined longitudinally towards the drain cover 310. In a Figure 29 In the alternative design variant shown, the channels 320 are flat in the longitudinal direction and are only inclined perpendicular to the longitudinal direction towards the fold 321.

[0091] While the folds 321 are in the in Figure 29 In the illustrated embodiment variant, the folds 321 preferably extend over the entire length of the channels 320, and extend in the Figure 28 The illustrated design variant preferably extends only over a partial length of the channels 320 up to the edge near the drain cover 310.

[0092] Furthermore, the drainage surfaces 322 of the channel 320 are inclined with a slight gradient towards a fold 321 running in the longitudinal direction of the channel 320, so that water flowing from slabs or tiles that are applied to the gradient wedges 2a, 2b in the direction of the drain 300 is directed towards the drain cover 310 and from there into the slot 311.

[0093] The drain cover 310 can also be designed in the same way as the channels 320 with formed drain surfaces 313 with a slope which are inclined towards a fold 312, wherein the fold 312 extends in extension of the slot.

[0094] As further explained in the Figures 30 , 31 and 32 As shown, in this embodiment the sound insulation panel 6 is arranged between an underside of the support base 41 of the base frame 4 designed as a tub and the superstructure element 500.

[0095] Accordingly, the soundproofing plate 6 has a passage 61 through which outflowing water from the drain chamber 360 can flow further into the odor trap 35 and the pipe section 38 connected to it.

[0096] The assembly element 500, unlike the one in Figure 9 The illustrated version of the assembly element 5 has several slots 521, 522, 523, 524 into which the pipe section 38 can be inserted.

[0097] This allows for easy adjustment of the pipe section 38 to the position of the wastewater pipe to which it must be connected during installation. Depending on the intended drainage direction, the slots 522 to 524, which are closed towards the edge in the illustrated embodiment, can be opened up in the area of ​​the edge of the mounting element 500, as shown by slot 521, so that during on-site installation of the drain, the mounting element 500 offers the possibility of aligning the pipe section 38 towards any edge of the mounting element 500.

[0098] The assembly element 500 also has a cutout 510 for receiving the odor trap 35. The cutout element 530 created when the cutout 510 is cut out preferably serves to secure the position of the odor trap 35 and can accordingly be inserted into the cutout 510 below the odor trap 35.

[0099] The thickness of this cutout element 30 is adjusted accordingly to prevent the odor trap 35 from settling downwards beyond a small amount of play.

[0100] The Figure 31 and 32 The diagrams again show the structure of the floor assembly 1 in respective sectional views, analogous to the... Figure 21 and 22 .

[0101] The bottom 340 of the channels 320 rests fully on the bottom 41 of the base frame 4, which is designed as a trough.

[0102] The interior of the channels 320 is preferably filled with a material 330. Polymer concrete is particularly suitable as the material 330. Other filling materials are also conceivable.

[0103] The channel 320 and the drain cover 310 are preferably made of stainless steel. Other materials are also conceivable. It is also possible to construct the channel in multiple parts, for example, with a cover made of stainless steel containing the drain surface 322, and another made of a different material, such as a dimensionally stable plastic, containing the base 340.
