Method for installing a bath or shower tray support using height adjustment devices

Description

[0001] The invention relates to a method for erecting a bath or shower tray support by means of height adjustment means and to a bath or shower tray support comprising a single-part or multi-part bath or shower tray support made of particle foam, such as EPS or EPP, which is foamed with a bulk density between 20 g / l and 90 g / l and has a substantially closed cover side for covering with tiles or another surface covering.

[0002] Bath or shower tray supports have become established as substructure elements for a bathtub or shower area. Bath or shower trays are often mounted on these supports; however, especially in floor-level shower areas, only tiles or other surface coverings are often applied.

[0003] When installing such bathtub or shower tray supports, it is of course very important that the bathtub or shower tray support is both vertically aligned and securely anchored to the subfloor. This work requires care and craftsmanship.

[0004] DE 20 2016 101225 is an example of a state-of-the-art shower tray structure. 1

[0005] The object of the present invention is to further simplify the method for erecting a bathtub or shower tray support, in particular to reliably ensure that the bathtub or shower tray support is aligned vertically and securely anchored. Furthermore, a bathtub or shower tray support is to be proposed that is particularly suitable for implementing this method and has corresponding configurations.

[0006] From a procedural point of view, this task is made possible by the following sequence of steps.

[0007] A method according to claim 4 for erecting a bath or shower tray support is proposed, comprising a single-part or multi-part bath or shower tray support made of particle foam, such as EPS or EPP, which is foamed with a bulk density between 20 g / l and 90 g / l and has a substantially closed cover side for covering with tiles or another surface covering, wherein the bath or shower tray support has height adjustment means on an underside opposite the cover side in order to be able to pre-adjust the installation position of the bath or shower tray support, comprising the following steps: Providing the bath or shower tray support, adjusting the bath or shower tray support on a substrate in order to set the desired installation position, providing the substrate and / or the bath or shower tray support on its underside with a sufficient amount of two-component foam (assembly foam) and placing the bath or shower tray support on the substrate and pressing it down until the height adjustment means are in contact with the substrate so that the installation position of the bath or shower tray support is fixed by the assembly foam and the height adjustment means do not have a load-bearing function with regard to later use of the bath or shower tray support, but the load is borne by the hardened two-component foam.

[0008] In terms of device technology, the object is achieved by a bath or shower tray support according to the features of claim 1.

[0009] According to a key consideration in this context, a bath or shower tray support is proposed, comprising a single-part or multi-part bath or shower tray support made of particle foam, such as EPS or EPP, which is foamed with a bulk density between 20 g / l and 90 g / l and has a substantially closed cover side for covering with tiles or another surface covering, wherein the bath or shower tray support has height adjustment means on an underside opposite the cover side in order to be able to pre-adjust the installation position of the bath or shower tray support, in particular designed to carry out the method according to one of claims 4 to 6.

[0010] A characteristic of the present method and of the bath or shower tray support is that height adjustment means are provided on the bath or shower tray support in order to pre-adjust the installation position of the bath or shower tray support. The actual foundation of the bath or shower tray support is then provided by a sufficient quantity of two-component foam (assembly foam), which then supports the bath or shower tray support over its entire surface, preferably almost completely, more preferably completely. The height adjustment means are therefore only required, on the one hand, to adjust the vertical or desired installation position and, on the other hand, to embed the bath or shower tray support in this installation position in the not yet cured two-component foam (assembly foam). After the assembly foam has cured, the height adjustment means are no longer necessary and, in a special embodiment of the present invention, can also be removed.

[0011] The height adjustment means are also accessible from the top side of the bath or shower tray support and in a preferred embodiment it is possible, for example, that the height adjustment means can be or are operated even when the bath or shower tray support is placed on the surface before or after the two-component foam is applied.

[0012] This significantly simplifies the initial height or pre-adjustment, as the bathtub or shower tray support does not need to be lifted from the subfloor during the height adjustment process. Regardless, subsequent adjustment can also be performed at a time when the two-component foam (assembly foam) has already been applied and has not yet cured.

[0013] In a preferred development of the present method, the height adjustment is performed via the height adjustment means in a predetermined sequence, preferably such that the height adjustment means located furthest from a wall surrounding the bathtub or shower tray support in the installed position is the first to be adjusted to the desired height. The area of ​​the bathtub or shower tray support associated with the height adjustment means located furthest from a surrounding wall is the area that projects furthest into the room. It is precisely here that a level connection to the surrounding floor covering, particularly in many cases a flush connection, is crucial.In this respect, the absolute height level of the bath or shower tray support can first be adjusted using this height adjustment device and then a vertical adjustment can be made using the further height adjustment device in relation to the absolute level specified by the first height adjustment device.

[0014] In terms of device technology, the height adjustment means correspond to recesses by means of which the height adjustment means are accessible from the top side of the bath or shower tray support.

[0015] The height adjustment means are provided as pin-like elements which are provided with an external thread and are guided by means of the external thread in a receptacle provided with an internal thread in the bath or shower tray support.

[0016] In a first optional further development outside the scope of the invention, it is conceivable that the receptacle for the pin-like elements is incorporated directly into the material of the bath or shower tray support, namely the particle foam.

[0017] The present invention specifies that the receptacle for the pin-like elements is incorporated in a separate receptacle element, wherein the receptacle element is attached to the underside of the bath or shower tray support or is incorporated into it.

[0018] According to the invention, the receiving element is designed in the manner of a nut, in particular in the manner of a hexagon nut.

[0019] In a further developed embodiment, the nut can be provided with a collar which, in the assembly position, faces the underside of the bath or shower tray support, with which the nut is supported on the underside of the bath or shower tray support.

[0020] Finally, it is provided that the pin-like elements have a guide head facing the cover side, with which the pin-like elements are each supported on the wall of the recess.

[0021] The invention will be explained in more detail below with regard to further features and advantages by means of the description of exemplary embodiments and with reference to the accompanying drawings.

[0022] Here we show: Figure 1 is a schematic sectional view of a first embodiment outside the scope of the invention; Figure 2 shows a sectional view of a modified embodiment according to the invention; Figure 3 shows an illustration of the height adjustment of a shower tray support in a corner of a room associated with two walls; Figure 4 shows a view of the embodiment according to Figure 1modified embodiment outside the scope of the invention; Figure 5 shows a further modification of the embodiment according to Figure 1 modified embodiment outside the scope of the invention; Figure 6 a sketchy explanation of a possible design of the recess in a shower tray support for use in the embodiment according to Figure 5 .

[0023] In Figure 1is a schematic sectional view through a shower tray support 11 provided with height adjustment means, having a cover side 12 located on top in the installed position and an oppositely arranged underside 13. The shower tray support 11 is shown here only in a sectional view, wherein two of the total of four height adjustment means 14 are illustrated in the shown sectional view. In a shower tray support with a square or rectangular basic shape, the height adjustment means are each assigned to the corners, wherein the height adjustment means could be offset backwards from the corners, for example, by approximately 7 to 20 cm in such a way that the height adjustment means result in a grid in a square or rectangle following the outer shape of the square or rectangular shower tray support.

[0024] At the Figure 1In the illustrated embodiment, the shower tray support is made of particle foam, preferably EPS or EPP, foamed to a bulk density of, for example, 50 g / l. Recesses 15 are provided in the shower tray support 11 corresponding to the position of the height adjustment means 14. The recesses 15 form receptacles 19 which are provided with an internal thread 18 which is incorporated directly into the material of the particle foam. Pin-like elements 16 which have an external thread 17 corresponding to the internal thread 18 of the shower tray support 11 are received in the receptacles 19 provided with an internal thread 18. The pin-like elements 16 can be adjusted in their height relative to the shower tray support by twisting them according to the pitch of the external thread 17 and internal thread 18.For this purpose, the height adjustment means 14 can be provided at one of their distal ends (or at both distal ends) with a tool engagement, for example a slot or a Phillips slot or a hexagon socket.

[0025] The pin-like elements 16 can also be made of particle foam, in particular of the same material as the shower tray support 11, which is particularly suitable for recycling reasons. Of course, it is also possible to form the pin-like elements 16 from a different material.

[0026] If the receptacles 19, as in the embodiment according to Figure 1are designed as through-holes and the pin-like elements 16 also have tool engagement means on their upper side, the height adjustment means 14 can also be adjusted from above, i.e., even when the shower tray support is already placed on the ground. This allows for particularly convenient adjustment of the height adjustment means 14.

[0027] In Figure 2 is a difference compared to the embodiment according to Figure 1 modified embodiment for height adjustment means 14, which can be provided in a shower tray support 11. There, too, the height adjustment means 14 can be assigned to the corners of the shower tray support 11, so that a total of four height adjustment means are provided for a square or rectangular shower tray support, wherein in Figure 2 According to the sectional view, only two height adjustment means 14 are visible.

[0028] While the height adjustment means 14 Figure 1 are guided in a receptacle provided directly in the shower tray support 11, the embodiment according to the invention provides Figure 2 separate receiving elements 20, which are inserted into recesses of the shower tray support 11. In the receiving elements 20, the corresponding internal thread 18 provided for the external thread 17 of the pin-like elements 16 is then formed in a corresponding receptacle 19.

[0029] The embodiment according to the invention Figure 2It is particularly suitable for variants in which the internal thread 18 is not to be formed by the material of the shower tray support, for example, to provide a smoother internal thread with a lower coefficient of friction. In this case, the pin-like elements 16 with their respective external thread 17 can, of course, also be formed from a material adapted to the material of the receiving element 20 with the internal thread 18.

[0030] The receiving element 20 can have a through-hole that is also open from above, so that the pin-like elements 16 can also be actuated from above. Alternatively, it is possible, as in Figure 2 illustrates that the receiving elements 20 are closed at their upper side, forming a receptacle 19 in the form of a blind hole. This allows a smooth cover side 12 of the shower tray support 11 to be maintained.

[0031] In Figure 3The positioning of a shower tray support 11 in a corner of a room formed by two walls 21, 22 is illustrated. Figure 3The illustrated shower tray support 11 comprises four height adjustment means 14, which can be adjusted separately from one another, preferably also from the cover side of the shower tray support. Although an adjustment of the shower tray support is in principle possible in any order in which the height adjustment means 14 are actuated, it is nevertheless preferred to first adjust the height adjustment means furthest from a wall surrounding the bath or shower tray support in the installed position to the desired height position in order to absolutely fix the height of the shower tray support to the desired level, for example, in particular for flush connection to an adjacent tiled surface. The remaining three height adjustment means can then be adjusted so that they ensure a perpendicular alignment of the shower tray support to the reference height adjustment means.

[0032] In Figure 4is a difference compared to the embodiment according to Figure 1 A further modified embodiment is illustrated, in which the receptacles 19 for the pin-like elements 16, which are open towards the cover side 12, can be closed with cover elements 23 after adjustment of the pin-like elements 16. In a preferred embodiment, the cover elements 23 are designed as circular cylindrical discs that can be inserted into a cover-side extension 24 of the receptacle 19 and are held in place by a clamping or friction fit by the material of the shower tray support 11, specifically by the particle foam. In one possible embodiment, the cover elements 23 are also made of particle foam, preferably of the same material as the shower tray support 11.

[0033] In Figure 5 is a further improvement compared to the embodiment according to Figure 4 The bath or shower tray support is shown in the Figure 5In the embodiment shown, it is provided with a continuous recess 15 which extends from the top side 12 to the underside 13. Within the recess 15, a nut 20 is inserted as a receiving element from the underside 13 of the shower tray support 11, which nut has a radially circumferential collar 26 for support against the underside 13 of the shower tray support 11. The pin-like element 16 has an external thread with which it is height-adjustable relative to the nut 20. At its end facing the top side 12, the pin-like element has a guide head 25 with which the pin-like element is supported against a wall of the receptacle 19, so that the pin-like element 16 is guided in the receptacle 19. At the same time, the guide head 25 has a tool engagement 27, which is designed, for example, as a hexagon socket, in order to be able to adjust the height of the pin-like element 16 using a tool (not shown).The tool engagement, which is preferably designed as a hexagon socket, can be provided for an external hexagon of size "10" (10 mm), so that the pin-like elements can be adjusted in height using conventional tools.

[0034] In Figure 6 The cross-section of the recess 15 from the underside 13 of the shower tray support 11 is also illustrated in sketch form. In a first section facing the underside 13, the recess has a profile adapted to the outer contour of the nut, preferably a hexagon nut. In an adjoining section, which preferably extends to the cover side, the recess 15, however, has a cylindrical profile, so that a likewise cylindrical guide head 25 of the pin-like element 16 can be supported against the wall of the recess.
