Shower tray (1) with a hard foam layer (5) and a cover layer (6),
characterized,
that the rigid foam layer (5) is made at least substantially or exclusively of XPS and/or
that the shower tray (1) has a support plate (9) extending at least substantially into the edge region of the shower tray (1) on the underside of the rigid foam layer (5) for load distribution.

Description

The present invention relates to a shower tray according to the preamble of claim 1 or 5 and a shower arrangement according to the preamble of claim 14.

There are different types of shower trays. These have different disadvantages. Shower trays made of polymer concrete are very heavy but stable. Shower trays made of cast plastic panels are also relatively heavy and do not have an optimal surface. Shower trays made of acrylic require a special support structure and are sometimes relatively flexible. Shower trays made of acrylic as a top layer and with a rigid foam layer made of polyurethane are therefore also available.

The present invention is based on the object of providing an improved shower tray and an improved shower arrangement which enable simple, quick and/or cost-effective installation.

The above object is achieved by a shower tray according to claim 1 or 5 or by a shower arrangement according to claim 14. Advantageous further developments are the subject of the subclaims.

According to one aspect of the present invention, the proposed shower tray preferably has a rigid foam layer made of XPS. This enables the production of a light but nevertheless very stable shower tray, in particular since XPS is closed-cell and hydrophobic and is therefore ideally suited for production.

According to another aspect of the present invention, the proposed shower tray has a support plate under its hard foam layer, which extends at least substantially to the edge of the shower tray and thus enables optimal load distribution and high stability of the shower tray. This also contributes to easy installation of the shower tray.

Preferably, the shower tray is supported on the underside by feet on a building surface. It is particularly preferred if the feet can be attached directly to the shower tray or its supports, so that no other supporting structure is required.

For example, the feet can first be attached to the subfloor and adjusted to the desired height so that the shower tray can then simply be placed on the feet. This allows optimal positions for the feet to be selected depending on the subfloor on site.

Alternatively or additionally, it is also possible to attach the feet directly to the shower tray or its supports, in particular by gluing them.

According to the proposal, this results in a particularly preferred shower arrangement with the shower tray, which is particularly easy to manufacture and is characterized by high stability.

According to another aspect of the present invention, the shower tray preferably has a cover in a drain opening, wherein the cover is arranged in the drain opening at a distance from the edge. The cover is held in particular in a form-fitting manner by one or more retaining elements on the underside and/or in corner areas and/or is designed like a plate and provided with a reinforcing element. Alternatively or additionally, a cover layer of the shower tray extends into the drain opening and particularly preferably over the corner areas and/or retaining elements on the underside. This enables a very stable, easy-to-clean design of the shower tray, whereby good water drainage is also easy to achieve.

2 shows a shower arrangement 20 with the shower tray 1 in a schematic partial section in an edge region of the shower tray 1.

As in the example shown, the shower arrangement 20 preferably has one or more feet 21 that support the shower tray 1. However, other structural solutions are also possible.

The shower arrangement 20 preferably has at least one partition wall 22 which is 2 is only indicated schematically and is arranged, for example, in an edge area of the shower tray 1 or step surface 2 and/or on an edge 3 of the shower tray 1. However, other constructive solutions are also possible.

Preferably, the partition wall 22, designed for example as a pane, delimits a shower space formed above the shower tray 1.

In addition or as an alternative to the preferably fixed partition wall 22, the shower arrangement 20 can also have a movable door and/or the shower room can be laterally delimited by a room wall (not shown) or the like.

The shower tray 1 preferably forms a step surface 2 of the shower or shower arrangement 20. Optionally, the shower tray 1 or step surface 2 can be provided with an anti-slip coating.

The shower tray 1 preferably has a raised, horizontal and flat and/or lateral edge 3, as in 1 which can be formed on one or more sides as required and in particular extends or rises upwards above the shower or step surface 2. However, other constructive solutions are also possible.

The shower tray 1 is preferably at least substantially angular or square in plan view.

The shower tray 1 is preferably at least substantially plate-like and preferably has a low overall height, particularly preferably less than 5 cm, in particular approximately 3 or 4 cm.

The shower tray 1 is preferably designed to be relatively light. In particular, with a maximum or edge thickness of 4 cm, the mass of the shower tray is less than 25 kg for a size of 140 cm x 90 cm, in particular less than 20 kg per square meter for an edge thickness of 4 cm.

The shower tray 1 is preferably provided with a drain and for this purpose has in particular a cover 4 which covers the drain or a drain opening 11 (cf. 3 ) covers.

In the following, a preferred structure of the proposed shower tray 1 is described using 2 discussed in more detail.

The shower tray 1 preferably has a rigid foam layer 5, which particularly preferably forms a core of the shower tray 1 made of rigid foam.

The core or the rigid foam layer 5 preferably forms at least more than 50%, in particular more than 70% or 80%, particularly preferably approximately 90% of the thickness or the total volume of the shower tray 1.

The rigid foam layer 5 is preferably made at least substantially or exclusively from XPS, i.e. extruded polystyrene.

Preferably, the hard foam layer 5 is formed in one piece.

The hard foam layer 5 is preferably more than 1 cm or 2 cm, in particular about 3 cm thick.

The rigid foam layer 5 or the XPS preferably has a density of more than 20 kg/m ³ , particularly preferably about 30 kg/m ³ or more.

The shower tray 1 preferably has a cover layer 6. The cover layer 6 or its surface preferably forms the step surface 2.

The cover layer 6 preferably forms a smooth and/or finely structured surface of the shower tray 1, which is particularly preferably sufficiently slip-resistant for a user.

The top layer 6 is preferably made of hard varnish or gelcoat.

Alternatively or additionally, the cover layer 6 is made of acrylic and/or fiber-reinforced.

The cover layer 6 is preferably arranged on a support layer 7, in particular on a support layer in the form of a glass fiber layer.

The base layer 7 is preferably substantially thicker than the surface layer 6.

Alternatively or additionally, the cover layer 6 can also be made of acrylic, in particular of fiber-reinforced acrylic. In this case, the carrier layer 7 can optionally be omitted.

The covering layer 6 and/or supporting layer 7 is optionally connected to the rigid foam layer 5 via an intermediate layer 8.

Particularly preferably, an assembly adhesive is used to form the intermediate layer 8 or to connect the cover layer 6 and/or glass fiber layer 7 and/or the rigid foam layer 5.

The cover layer 6 and optional layers 7 and/or 8 preferably extend from the top of the shower tray 1 or hard foam layer 5 laterally over the edge of the shower tray 1 or hard foam layer 5.

The shower tray 1 preferably has a support plate 9, which is arranged below the hard foam layer 5 and serves to distribute the load. In particular, the shower tray 1 is designed to be self-supporting, i.e. sufficiently stable, so that even with only point support, a load of more than 100 or 120 kg, as is usual with showers, is easily possible.

The carrier plate 9 is preferably connected directly to the rigid foam layer 5, in particular via a connecting layer 10 or an adhesive. In particular, assembly adhesive can be used for this purpose.

Preferably, the carrier plate 9 is integrally connected or glued to the rigid foam layer 5.

The carrier plate 9 preferably extends at least substantially into the edge region of the shower tray 1 or up to the edge of the shower tray 1 or hard foam layer 5.

The support plate 9 serves in particular to distribute the load when the shower tray 1 is supported directly by one or more feet 21 on the underside. The point-based introduction of force by the feet 21 can therefore be better distributed. In particular, the shower tray 1 is self-supporting and does not require any additional support structure on the underside.

The feet 21 are preferably first fixed on site, for example by gluing and/or screwing. The feet 21 are preferably adjustable in height. The shower tray 1 can then be placed on top and preferably glued to the feet 21. This enables very simple and quick assembly.

Alternatively, it is also possible to first attach one or more feet 21 to the shower tray 1 or support plate 9 and then place the shower tray 1 together with the feet 21 on the building site in the desired manner.

The carrier plate 9 is preferably designed as a sheet metal or metal plate and/or made of steel, stainless steel or aluminum.

The thickness of the carrier plate 9 is preferably at least 0.5 mm, more than 0.6 mm, particularly preferably more than 0.7 mm, in particular about 0.8 mm.

The drain opening 11 is covered by the cover 4. Preferably, the cover 4 is walkable and/or at least positioned substantially flush with the floor in relation to the step surface 2 of the shower tray 1, but can be lifted.

The cover 4 is preferably held or received in the drain opening 11 at a distance from the edge, particularly preferably in such a way that a circumferential gap 19 is formed through which the water can easily drain when using the shower tray 1 or shower arrangement 20. However, other structural solutions are also possible, for example the cover 4 can additionally or alternatively be provided with openings to the water compartment.

The cover 4 is preferably plate-like and/or flat and/or has a thickness between 0.8 and 1.8 cm.

The cover 4 is preferably substantially rectangular or square in plan view.

The cover 4 particularly preferably has an integrated reinforcing element 17, which is in particular designed in the form of a grid and/or a plate.

The reinforcing element 17 is preferably made of metal and/or completely integrated into the cover 4.

The cover 4 is preferably made of polymer concrete or plastic and/or provided with a cover layer 6 (not shown), which is particularly preferably designed like the cover layer 6 of the shower tray 1.

3 shows the shower tray 1 in the area of the drain opening 11 in a schematic section along a diagonal of the cover 4.

In the example shown, the drain opening 11 has a receiving area for the cover 4, which preferably comprises a flange-like support or a shoulder 14, which at least indirectly holds or supports the cover 4.

In the example shown, the cover 4 is preferably held in a form-fitting manner in the drain opening 11 at a distance from the edge. This is done in particular via a holding element 12 or several holding elements 12, which particularly preferably engage from below in the cover 4 or recesses 18 of the cover 4.

Alternatively or additionally, the shower tray 1 or drain opening 11 or the receiving area or shoulder 14 is preferably provided with corner areas 13 and/or other supports in order to hold the cover 4 at the desired height. However, other structural solutions are also possible.

The holding elements 12 and/or corner regions 13 are preferably formed by the cover layer 6 and/or covered by it.

In the example shown, the holding regions 12 and/or corner regions 13 are formed or shaped in particular by assembly adhesive or another material and optionally covered by the cover layer 6.

In the example shown, the shoulder 14 preferably merges into a particularly conical section 15 towards the center in order to finally form a preferably circular opening for a drain (not shown).

The drain opening 11 preferably ends at the bottom in a circular conical area that tapers downwards so that the drain opening 11 forms a circular outlet. However, other structural solutions are also possible.

Preferably, the cover layer 6 extends into this section 15 or to the opening formed or the lower edge of the drain opening 11, as in 3 indicated schematically.

The shoulder 14 and/or the section 15 are preferably formed by the carrier layer 7 or molded onto it. The shoulder 14 and the section 15 are particularly preferably reinforced in order to withstand the loads when using the shower tray 1, for example when stepping on the cover 4 and/or when attaching the drain.

The shoulder 14 and/or the section 15 is/are preferably supported and/or lined on the underside, in the example shown by a filling area 16 which is filled in particular with assembly adhesive or another suitable material. The filling area 16 preferably ends flush with the support plate 9, so that a flat or smooth underside of the shower tray 1 is formed.

The support plate 9 is cut out to surround the drain opening 11 at a distance if necessary and to enable installation of the drain (not shown).

The shower tray 1 can preferably be installed at least substantially at ground level. In particular, the shower arrangement 1 enables an entry at least substantially at ground level. However, the shower tray 1 can optionally also be arranged on an upper floor (not shown).

The shower tray 1 preferably has a modulus of elasticity of more than 50 kN/mm ² or 60 kN/mm ² , and/or less than 200 kN/mm ² or 150 kN/mm ² , in particular less than 100 kN/mm ² .

Preferably, the bending stiffness of the shower tray 1 is more than 300 kNcm ² /m.

Preferably, the shower tray 1 or its cover layer 6 on the top side or on the shower room side has a roughness of more than 1 µm or 10 µm, particularly preferably more than 20 µm or 50 µm, in particular more than 100 µm or 200 µm, and/or less than 1000 µm or 800 µm, particularly preferably less than 600 µm or 500 µm, preferably wherein the roughness is the average or arithmetically averaged roughness R _a according to EN ISO 4287:2010 is.
