DESCRIPTION

Installation wall

The invention relates to an installation wall according to the preamble of claim 1.

As is well known, installation walls for wet rooms are used not only to separate rooms but also to attach partition walls, sanitary components and other additional components such as shelves, cupboard inserts, etc. They are also used to accommodate installation equipment such as pipes for supply and disposal as well as electrical cables. There are also other building physics functions such as thermal insulation, sound insulation or even more architecturally oriented functions that affect the surface design.

BLZ 250 5*0*0 00l,*Kto.*-NT.2£-1*1Se?5· Bistgiigtomo: Postgiroamt Hannover iSlZ2S0 10030}, K\o.-U*.667-1S-X

Oil-based construction generally requires additional measures for thermal insulation and is - if you take into account the sanitary objects to be attached to the installation wall - characterized by a juxtaposition of different

materials, each of which has a completely different aging and wear behavior. For reasons of strength, heavy sanitary components can often only be mounted on specially designed
prepared places on the installation wall, so that subsequent changes can also be made
involve structural changes and therefore a comparatively high level of expenditure.

The industrial prefabrication of these installation walls with regard to the diverse functions shown above is limited insofar as
Extensive prefabrication on-site flexibility
This is particularly important when these installation walls are used in the modernization of old buildings, where not only dimensional adjustments have to be made,
but also has to work under extremely cramped conditions.

The building materials commonly used in construction are in many cases castable, in their initial state or under the influence of heat, plastic
deformable masses. For example, inorganic masses based on cement or other
hydraulic binders or ceramic masses ■ are used.

A particularly advantageous, usable in construction
Material is seen in the group of geopolymer materials, which are available in numerous modifications, e.g.

-3-

Oil can be used in both foamed and unfoamed form and, in particular, in the unfoamed state, they essentially have the properties of ceramic materials, although the plant- and energy-intensive firing process characteristic of the latter group of materials is not required, since these materials harden in a mold at temperatures below 100° C.

These geopolymer materials are known in principle, for example, from DE 32 29 339 C2, DE 33 03 409 C2 or from "Ceramic Matrix for Composites" (Ceram. Eng. Sci. Proc, pages 835 to 841). In the initial mixture, these consist of a solid mixture of oxides containing amorphous SiO ₂ and aluminum oxide in combination with a water-containing amorphous, disperse-powder silica and fillers such as barite, zircon sand, mica, waste from bauxite melt, basalt powder, quartz, feldspar, granite rubble, etc., as well as an aqueous potassium-alkaline potassium silicate solution. The mass consisting of these components can be placed in a mold and hardened in it. Using a foaming agent, the part produced in this way can also be designed as a foam component. A particular advantage of this group of materials is that they can be shaped as desired using conventional machining processes such as drilling, sawing, milling, a point of view that is of great importance when making subsequent changes to manufactured components. Furthermore, these components can be bonded together using homogeneous material, ie

using a geopolymer material as an adhesive to form larger, completely homogeneous assemblies.

It is the object of the invention to provide an installation wall

-4-

To design the oil of the type described at the beginning in such a way that it can be handled flexibly during assembly, combines all building physics functions and is made of largely homogeneous material.

This object is achieved in such an installation wall by the features of the characterizing part of claim 1.

The essential aspect of the invention is that the installation wall in its simplest form consists of a layer made of a geopolymer material, which is homogeneously bonded on one side to holding bodies designed as molded parts for sanitary components. The sanitary components can be, for example, toilet blocks, but also holding bodies for bathtubs, wash basins and the like. Finally, cabinet inserts, shelves, supports for lighting fixtures, etc. can also be designed as molded parts made of geopolymer materials and bonded directly to the layer mentioned. There are no restrictions on spatial placement when bonding and this can be done at any point on the layer. It is essential that the layer mentioned is sound-insulating with other parts of the building, e.g.

a room partition wall or a floor, so that the transmission of structure-borne noise, for example the transmission of flow noise to other parts of the building, is effectively prevented. Since - as already explained above - the geopolymer material can be easily cut to the dimensions specified by the building site, it is possible to provide the layer in the form of prefabricated panels, which are cut to size according to the

-5-

Ol can be carried out individually according to local conditions. At the same time, it is possible to make the layer mentioned at least partially foamed or to provide several layers, at least one of which is foamed, so that the installation wall according to the invention simultaneously has sufficient thermal insulation. If the installation wall consists of several layers that are directly connected to one another, this connection can in turn be based on a homogeneous bond. Furthermore, there are very simple ways of forming cavities in the layer, which in turn can be used as media lines, for example to accommodate supply and disposal pipes. In the case of a compact, i.e.

unfoamed geopolymer material, it is also possible to use these cavities directly as media lines. Finally, electrical installation equipment can also be accommodated in such cavities. The further design of this layer, especially on the surface, is also particularly simple, as it can be covered in any way, for example with tiles or another decorative coating.

The features of claim 2 are directed to the more detailed nature of the sound-insulating layer. This can consist of organic materials such as rubber granulate, cross-linked polyethylene or polyurethane or other organic plastics, in particular organic foam plastics. This sound-insulating layer is preferably adhesively bonded to the adjacent layers of geopolymer materials.

The features of claims 3 and 4 are directed to the connection

-6-

Ol connection of the sanitary components, in particular their supporting or receiving bodies, with the installation wall on the one hand and the adjacent floor areas of the respective building on the other. It is therefore essential that an installation that is isolated on all sides with regard to the transmission of structure-borne sound is aimed for, so that sound transmission to adjacent building structures is effectively counteracted. The sound-insulating layers used here can be those that correspond in material terms to the sound-insulating layers that are already used in the actual installation wall. As an alternative to this or in addition to this measure, the respective receiving bodies for tubs can themselves be provided with sound-insulating linings, which form the link to a metal tub, for example.

The features of claims 5 and 6 are directed at the further design of the installation wall with regard to its heat and sound insulation properties. The layer of geopolymer foam material, which mainly serves for heat insulation, is covered by a sound-insulating layer at least on its side facing a room partition wall and can also be covered with another sound-insulating layer on its side facing the wet room.

The features of claims 7 and 8 are directed to the design of the layers forming the wet room-side finish of the installation wall. These layers fulfil, among other things, a load-bearing function and can be designed in accordance with the expected static load, in particular also depending on their absolute

-7-

Ol dimensions should generally be reinforced. The outer layer on the wet room side in particular is mainly used to connect relatively heavy sanitary components and is dimensioned accordingly. It is sufficient if this extends, for example, only over half the height of the room, so that it also forms a storage area on the top. This storage area can be widened in the simplest way, so that a table-like structure is created.

The features of claim 9 are aimed at further decoupling the installation wall from other building structures in terms of vibration. It is therefore essential that all layers of the installation wall are supported on a sound-insulating layer on the floor side, so that no sound is transmitted, particularly in the direction of the floor. The layers can also be connected in the same way in their connection area to the ceiling of a room with the interposition of sound-insulating layers made of the same material.

All layers of the installation wall according to the invention are bonded to one another in accordance with the features of claim 10, whereby a materially homogeneous bond is aimed for as far as possible and preferably.

The features of claims 11 and 12 make it clear that the principle according to the invention can also be used for partition walls within wet rooms, such as those required for shower cubicles, toilets, etc. These partition walls preferably consist of a geopolymer material, which is structurally designed, for example, as a functional unit with a shower tray or the

-8th-

—&ogr;— ■*·

Ol receiving body for a shower tray can be designed. These partition walls or the aforementioned receiving body are in turn connected to the installation wall on the one hand and the floor of the respective room on the other hand, with sound-insulating layers in between.

The individual layers forming the installation wall consist, in accordance with the features of claim 13, of individual geopolymer panels that are industrially prefabricated and are only bonded together homogeneously around the perimeter on site to form larger assemblies. Due to the low density, comparatively large panels can be prefabricated, so that assembly times on site are correspondingly shortened.

The cavities incorporated into the individual layers or plates according to the features of claim 14 can be used for installation purposes, for example to accommodate pipes and electrical cables, but can also be used directly for media routing.

The mounting bodies for sanitary components and equally the aforementioned partition walls can themselves be coated in the surface area at the factory, for example covered with tiles, whereby the on-site assembly of the complete installation wall and therefore the creation of the respective wet room can be further shortened, since the assembly is limited to the front-side bonding of these components to the other parts of the installation wall.

It can be seen from the above that the installation wall according to the invention, including the associated sanitary components, can be constructed from a few modular parts.

-9-

Oil is characterized by a high degree of material homogeneity and combines all building physics properties such as statics, thermal insulation, sound insulation, room separation, etc. It is

•05 Furthermore, depending on the degree of industrial prefabrication, it is easy to assemble.

In the drawing, 1 designates the floor of a building on which a room partition wall 2 stands. The connection between the room partition wall 2 and the floor 1 is shown only schematically and can vary in individual cases according to the material design. For example, the floor 1 can have a thermal insulation layer that is not shown in the drawing. Furthermore, a pipe system for conducting waste water can be integrated into the floor 1, which is also not shown in the drawing, but will be discussed in more detail below. Finally, the top layer of the floor 1 can also consist of a geopolymer material. The essence of the subject matter of the invention lies in the provision of an installation wall that has a specific structure that is particularly suitable for subsequent expansion measures, especially in the context of the modernization of old buildings. As will be explained in more detail below, the installation wall is not only designed with a view to certain building physics requirements, but also for the cost-effective installation and installation of sanitary components and thus for the complete construction of wet rooms.

3 denotes a layer of geopolymer foam material, which is connected to the room partition wall 2 with an intermediate layer 4 of a sound-insulating material, e.g. rubber. This

-10-

Ol layers can be connected to each other using a suitable adhesive, whereby within the framework of layer 4, old rubber granulate, but also an organic plastic, also foam plastic such as.

Polyurethane can be used. The layers 3, 4 mentioned are located on the side of the room partition wall 2 facing the wet room 5. Layer 3 is followed by a further layer 6, which corresponds to layer 4 in terms of material and is glued to layer 3 in a suitable manner. A layer 7 consisting of compact, i.e. non-foamed geopolymer material forms the wet room side end of the wall, at least in the upper area of the wall. 8 designates a further layer made of compact geopolymer material, which extends from the floor 1 over only part of the wall or room height. This layer 8 is preferably glued to layer 7 in a homogeneous manner and serves mainly for static reinforcement. This will also be discussed in more detail below.

Not shown in the drawing are mainly decorative coatings applied to the wet room side surface of layers 5 and 8.

9 designates a receiving body for a bathtub, which is designed as a cuboid and is equipped with a recess 10 on the top for receiving the tub body (not shown in the drawing). The receiving body 9 consists of a geopolymer material, which can be foamed or unfoamed and which is supported on the floor 1 with an interposition of a floor-side layer 11 made of a sound-insulating material. This layer 11, which - as can be seen at point 12 -

-11-

&eegr;—

Ol, which surrounds the base of the receiving body 9, leaving an edge, can be made of the same material as layers 4, 6. A layer 13, which in turn is made of the same material as layer 11, is located directly between layer 8, which forms part of the installation wall, and the receiving body 9, whereby this layer is bonded in a suitable manner on the one hand to the receiving body 9 and on the other hand to layer 8. It can be seen that the receiving body is arranged in a completely vibration-decoupled manner, so that the transmission of structure-borne noise to surrounding building structures is reliably prevented. 14 designates a layer of tiles, which otherwise forms the floor covering of the wet room.

15 designates a molded part made of a geopolymer material, which has two recesses 16 on the top side that are arranged at a distance from one another and are identical to one another, which serves as a receiving body for correspondingly designed wash basins.

The molded part 15 is bonded to the layer 8 in a homogeneous manner, i.e. a geopolymer material is used as the adhesive, which is preferably non-foamed. The bonding can preferably be carried out with an intermediate layer (not shown in the drawing) made of a sound-insulating material, which in turn corresponds to that of the layers 4, 6, 11, 13. As an alternative to this measure, the recesses 16 can be lined with such a material, so that the transmission of structure-borne sound from the sink inserts to the molded part and thus to the layer 8 is effectively prevented.

17 designates a receiving body for a shower tray (not shown in the drawing), which in the same

-12-

Ol rather like the receiving body 9 on the bottom side, but also on the wall side, ie on its, the layer 8
facing side soundproofed by arranging a
bottom layer 18 and a wall-side

Layer 19 is set up. 20 also designates a shower cubicle, the walls of which are made of
a geopolymer foam material, which is
an opening not shown in the drawing, whereby the walls of this shower cubicle 20 are connected to the layers 7, 8, in turn with the interposition of sound-insulating layers not shown in the drawing, ie are glued, which correspond materially to layers 4, 6. The shower cubicle 20 as a block is thus also installed in a vibration-insulated manner, so that no flow noise is transmitted from it to surrounding building structures.

Not shown in the drawing is a toilet block, which
which in turn can be bonded to layer 8 and
can be installed within the wet room 5 with the interposition of a partition wall consisting of a geopolymer foam material.

21, 22 are again made of a geopolymer material. existing molded parts, which are deposit plates
and are preferably bonded homogeneously to the layer 7 above the recesses 16. The molded parts 21, 22 are each located below mirrors 23, 24. 25, 26 schematically indicate the fittings assigned to the wash basins inserted into the recesses 16.

Not shown in the drawing are also cabinet and shelf components, which can be designed in the same way as molded parts and with layers 7, 8

-13-

-J.J—

Oil can be glued together to complete the wet room,

Also not shown in the drawing are installation facilities such as supply and disposal pipes, which are assigned to the shower cubicle 20, the washbasin, the bathtub and the toilet block (not shown). These can be accommodated in cavities in layer 3 - a layer of geopolymer material can also be integrated into the top layer of the floor 1, so that a pipe network for carrying waste water is integrated into it, which is also connected to a drain grate 27. However, this will not be discussed in more detail.

It is essential that the wet room created in this way is completely homogeneous in terms of its load-bearing components, is easy to assemble and leads to the construction of a wet room whose components are installed in a sound and heat-insulated manner, so that in particular the transmission of flow noise to surrounding building structures is prevented.

The wall layers 3, 7, 8 preferably consist of individual panels which are glued together on the periphery in a homogeneous manner in order to adapt to individual wall dimensions and, due to the special properties of the geopolymer materials, can be cut to the required dimensions by sawing in the simplest way if necessary. Due to the adhesive connections between the additional components of the installation wall and this, as well as the special way in which the support bodies 9, 17 are set up, there is a high degree of flexibility on site, so that industrial prefabrication of the components of the installation wall is possible with the proviso that the flexibility in the individual adaptation to the on-site dimensions and

Oil levels are not affected.
