UNDERBODY ELEMENT FOR SUPPORTING A SHOWER GROUND
ELEMENT
FIELD OF THE INVENTION
The invention relates to a sub-component to underpin a preferably with a cover
to
be allocated shower floor element, said base element and shower-floor element
outlet
opening for the installation of a drain pan are provided with one.
BACKGROUND OF THE INVENTION
Under shower floor elements are understood in this case in particular those
which
are to be installed at floor-level shower. Such shower floor elements will
include the brand
name "Fundo" (made by wedi GmbH, Emsdetten). The shower floor elements of a
mosaic
tile layer or layer and covered with masking. For square shower floor elements
there is a
drain hole for installation of a drainage pot in the middle, so the focus of
the square. There
is a corresponding gap using wastewater led the pot and drain off through.
Other designs
are known, such as rectangular or circular shower base, which may be provided
with
appropriate devices. The drain openings other positions, different from the
focal area of
the shower-floor element are also introduced.
With the installation of showers with a shower-floor element is based on a
building
substrate, such as here under a concrete floor, a thin screed or the like is
meant a
substructure on, the mortar bed is made than usual. If foam plate shower floor
panels with
circular cutouts, the drain body in advance of the discharge opening brought
in, not to the
outer contour of the drain pot is matched exactly, however, so that the drain
pan in its
installed position at first still has game (compare article "barrier-free
shower base
elements" from wediwelt, January 2000).
Below the positions of the shower-floor element, a bed placed, from the wet
and
malleable mortar or cement-based building material mixture is first. Here are
the outer
contour of the drain body and drain cavities left accordingly. After replacing
the shower-
floor element is the bed made up, the drain body and the process taking up a
form that is
-1-

embedded. Even if the drain body laid in the shower-floor element is fitted,
as the "fundo-
system" of the case, often remain in the bed voids that are missing from the
area in a
lining.
The disadvantage is that it is hardening of the bulk and heavy use of the
shower-
floor element to loosening and leaks in the drain pan and drain system can
come after, if
still remained in the bed or cavities are formed over time.
There is also the risk that the filling of the drain pan is not properly
carried out in
the field, so that the drain pan, over time, thus lowering the density of the
drainage system
is not longer given.
It is accordingly the object, a common model of shower floor base construction
elements adapted to indicate in advance the exact form, height and density may
be
permanent in the.
This object is achieved in a construction that is a sub-component to underpin
a
shower-floor element is characterized essentially in, with sub-component and
shower-floor
element outlet opening for installation of a drainage pot provided are graded
and the
foundation elements that the entire volume between the bottom of shower-floor
element
and the building substrate occupies a slab of foam plastic covers at least
that one of the
peripheral organization of at least one drainage pot adjusted opening and in
accordance
with the thickness of the foundation element reaching, the opening subsequent,
structured
lumen provided is on.
The sub-component assumes the role of the bed without finishing with stuffing
or
the like are done. The lumen, i.e. the inner contour of the opening, the outer
contour of one
or two pots of common sequence adapted to. The manufacturer of the drain pans
can be
adapted using the corresponding sub-components to build a shower assume that
complications and complaints concerning the conduct installation are
practically excluded.
Preferably, the sub-component consists of two or more stacked sheets. It is
thus possible
sentence of two or more, i.e. n plates, the construction site to supply one
with and
depending on the height of one or up to n-l disks, the top plate to give up,
for example.
The sub-component is considered to cover n substantially congruent disks, each
with the

peripheral design of the end pots custom openings and the thickness of the
foundation
element reaching, divided, the opening of subsequent, structured lumen
provided on
exception, in the state of installation perimeters and openings the plates of
the lower
component and the shower-floor element coincide.
As a technically advantageous has been found that the level of a first (lower)
plate
60 5 mm and the height of a second (upper) plate 30 5 mm, with a fixed
total amount,
egg 90 mm, however, should not be exceeded.
The heights of the plates and their number can be other embodiments of the
foundation element and, depending on the height of the pots vary in sequence.
These
dimensions are given as examples and each manufacturer to vary by product.
A particular advantage is that the lumen of the first panel in the installed
state, the
outer contour drainage pot with for example a height of about 60 mm takes up
one, so that
they can only serve as a foundation element. For example, if three plates of
40 + 30 + 20
mm with heights are chosen, so steps can be at heights of 20, 30, 40, 50, 60,
70 and 90 mm
height, "use".
When foam plastic for the lower component is preferably an expanded
polystyrene
foam (EPS) or extruded polystyrene foam (XPS) in question. However, it should
not be
excluded that the number of known foamable polymers, other materials for the
sheets are
suitable, such as polyurethane foams.
The flat sides of the foundation element and the underside of the shower-floor
element and the top of the substrate structure has a durable and long lasting
connection,
for example via an adhesive made between.
An extension of the applications can be achieved when separate openings and
corresponding Lumina for drain pans in the foundation elements are introduced
which are
foundation elements of at least two that in the installed state, each with a
drain hole of
different shower floor elements coincide in and with the end pots compatible.
Preferably a
hole is in the center and the other opening eccentrically.

Finally, the invention relates also to a set of components to create a
tileable shower
floor, comprising a shower floor element, a sub-component according to any
preceding
claim characteristics and a suitable drainage system.

DETAILED DESCRIPTION
Referring to Figure 1 there is shown a schematic section through a square in
plan
view shower floor structure 1, but without tile layout. For the shower floor
construction
includes a shower base element 2, the EPS or XPS foam plastic and consists of
a
waterproof coating is occupied with.
In the shower-floor element 2, for example as a further layer is a tile layer
(not
shown) is placed and glued. The shower-floor element 2 is integrally formed in
the present
case, has a decline towards the center, where an opening 3 into which a drain
pan 4 is
inserted. The drain pan 4 is siphon inner concentric cylinder 5 provided with
one, the
known fashion serves as a trap. At the end of pot 4 is followed by horizontal
water line 6
to one that a PVC plastic pipe is made, the corresponding piece of the drain
body 4 is
placed on one. The shape of the drain pot may vary and is only indicated
schematically.
To mortar structure below the shower-floor element 2 to avoid the usual, is
cover
under the shower-floor element 2 component 8, as depicted in Figure 2, uses
one plate
-4-

instead of the example of two overlapping, different heights plates, namely
the upper plate
7 and a bottom plate 9, as shown in Figures 3 and 4. The upper plate 7 and
lower plate 9
are congruent with each other in outline and have outline how the shower floor
element 2
rests on the same.
The top plate, upper plate 7, is about 30 mm thick and the lower plate, bottom
plate
9, about 60 mm. As the material foams in the present case, XPS and EPS
provided by a
specific bulk density of about 35 kg/m3 or 22.5 kg/m3. Depending on load and
embodiment, the density may vary.
Figure I shows that the lower component 8, the entire volume between the
bottom
of the shower-floor element 2 and a building substrate (not shown) holds. The
end of the
pot 4 is necessary for opening of the lower floor element is located exactly
below the
corresponding opening 3 of the shower-floor element 2 According to a common
design of
the drainage pot 4 are appropriate peripheral and lumen structures for the
opening of the
plates, being upper plate 7 and lower plate 9, were elected.
Figures 3 and 4 depict how the inner sides of the central openings 3 'and 3"
of the
upper plate 7 and lower plate 9 align, according to the expected design and
lowering depth
of the drain pan design. According to the illustrated embodiment, the opening
3' in its
upper range, first circular sunk. At about 2/3 of the height levels two stages
are provided
(not labeled for clarity), serving as the support for the drainage pot 4.
Down, the openness
of 3' narrows away, so that the cup part of the drain pan 4, the seal ring is
surrounded by
one, with no additional mortar or adhesives sealed in the opening 3'.
Be both base plates, being upper plate 7 and lower plate 9, required then they
may
be glued together. It should be noted that at extremely flat shower setups,
the lower plate 9
and plate 8 are used alone as a substrate element can. For this is necessary,
however,
accounts for the waste water down to the lead.
The thicker lower plate 9, the opening 3" bear the cross section of a so-
called drum
line as follows. Again, the outline and the inside of configurations
corresponding to the
periphery of the drain pot 4 in its lower part designed. The aforementioned
openings 3' and
-5-

3" are milled or punched. Such material processing can be applied combined.
The
necessary tools and processes are known.
If, as shown in Figure 1, horizontal connection of the sewage pipe 6 provided
one,
then the material of the lower plate 9 at the construction site, a
correspondingly wide slot
14 is cut in or cut.
As Figures 5 and 6 show the plates each contain a further bore 23 'and 23".
These
holes 23 ', 23", corresponding, positioned with upper plate 7 and lower plate
9 to be
coincident drain body elements outside the center, are congruent with built-
in, where
shower water is derived and recorded with. The opening 23' has a circular
cross section
and a wide aperture, the truncated cone converges and a hollow cylinder goes
into. The
opening 23" is its total height is a hollow cylinder made of. This option is
to create a
different standard sanitary drain positioned in the shower area to provide in
one. The lower
component 8 is therefore a wide range of soil-incorporated elements used in
shower.
To facilitate the craftsman on the site may also include devices set to create
a
tileable shower floor offered as a whole, the shower-floor element 2, a sub-
component 8,
consisting of the two plates upper plate 7 and lower plate 9, and a suitable
drainage
system.
The proposed elements, particularly the lower component can be tiled over and
installed a tile of. The result is a simple and inexpensive way to quickly
erect shower floor
construction.
