Abstract

The invention relates to a subfloor for rooms, in particular under floor coverings, wherein the subfloor has at least one subfloor layer (2) made of a corrugated material (1) and said subfloor layer or at least one of a plurality of subfloor layers (2) is filled with bitumen as a filler material (3). Such a subfloor is more easily produced and has greater stability if the corrugated material (1) extends perpendicular to the bottom surface (4) and the top surface (5) of the subfloor layer (2) and the corrugated material (1) has a corrugated (1') and at least one flat layer (1") in alternation.

Flooring for rooms

description

The invention relates to a padding base for rooms, in particular under floor coverings, wherein the padding substructure has at least one lining underlay layer of corrugated material and this or at least one pad undercoat layer is filled with a filling material, wherein the corrugated material is perpendicular to the base and top surface of the pad underlay layer and wherein the corrugated Material alternately has a corrugated and at least one flat layer.

Such a padding substructure is known from WO 2011/072867 A1. It has between two cover layers standing corrugated layers of non-brittle natural or synthetic mineral wool filled pulp polymer along with binder. The corrugated layers arranged at the edge of the padding base are covered by a flat layer which is arranged normal to the cover layers and connects them together. The well cavities formed between the corrugated layers are filled with a mineral granulate. However, this is not suitable for wet rooms, because the moisture can penetrate between the granules and can cause mold there.

From DE 10 2008 055 978 A 1, a padding substructure of the type mentioned above is known. There are surfacing layers of corrugated material, such as corrugated cardboard taught in which the corrugated material along the base and top surface of the lining underlay layer runs. The wave paths of the corrugated material may be filled with filler material, for example sand, quartz or silicon. Due to the layer course of the corrugated material, this has, especially if it is unfilled or not completely filled, no high stability. It is through

CONFIRMATION COPY the long and narrow cavities difficult to fill and the insulation is not optimal.

There are also honeycomb panels are known in which the honeycomb are filled from above with a filler. However, these have the disadvantage that they must be made with a mold that includes the honeycomb shape. The smaller one configures the honeycomb for reasons of stability, the greater the effort for the mold and the plate production. The invention has for its object to develop a padding substructure of the type mentioned in such a way that it is easy to produce, has a high stability and is waterproof.

The object is achieved in that the filling material is at least one covering layer bitumen bitumen.

The padding substructure is versatile. It can be used not only for floors but also for walls and ceilings. Either only for insulation or with facilities for heating or cooling.

Due to the alignment of the corrugated and flat material, which is perpendicular to a possible load, this has a very high load-bearing capacity, even if it is not or not yet filled with filling material. Since the cavities are very short due to the vertical orientation, it is very easy to fill them completely. Different materials are possible as filling material. This filling can already be done in the manufacture of prefabricated panels. But it can also be done after the installation of not yet filled plates on site, as without much effort in a simple way a pouring is possible. Expediently prove the corrugated material is constructed such that alternately a corrugated and a flat layer joined together, for example, are glued. Alternatively, a corrugated layer on both sides with one each level layer are joined together. Thereafter, by the joining together of strips of this corrugated cardboard-like designed basic element, the open-top structure is constructed areally. The vertical layers, alternately wavy and even, lead to a particularly high stability and allow a large load on a floor, which is equipped with this base pad. In this case, the corrugated material with the flat layers as corrugated as a piece of goods can be easily and inexpensively, either equal to strips according to the thickness of the desired lining underlay or large area, and then to cut the strips according to the desired thickness of the lining underlay. These strips can be easily joined together and possibly glued together to the desired

To produce surfaces, for example plates. So no mold is needed as in the production of a honeycomb form. By combining the corrugated with the flat layers of material, a higher stability is achieved than in the known honeycomb panels.

As filler bitumen is provided. The bitumen, especially if it is pure bitumen, is easily fluid liquefiable or can be in this state - even after the production of the same by distillation of petroleum - deliver. When the bitumen solidifies, it has a high thermal insulation. It is free of cavities after processing, especially without pores and has excellent internal insulation, comparable to rubber. The impact sound insulation at 20 mm is approximately 8 to 12 dB. By pouring the corrugated material with the flat layers with the bitumen, the padding substructure becomes water resistant even if it was not the non-poured material before.

The bitumen is a by-product in the industrial processing of crude oil, it is thus produced with low energy consumption and without additional environmental impact. It has no harmful components and can easily be recycled. For pouring the corrugated material with the planar layers pure bitumen is preferably used, since this is fluid enough from 160 ° C for the pouring out of the cavities of the material. Cellulose is expediently used as the corrugated material, preferably with a wood content of 98%. This material withstands heat by pouring pure bitumen. Conveniently, a water-repellent material is used that complies with the TAPPI test, a wet burst test. The bitumen can be enriched with sand, which further improves the insulation. The invention provides the following developments:

But instead of the hot bitumen cold bitumen can also be used, then no temperature resistance of the corrugated material and the intervening planar layers is required.

It is expedient if prefabricated panels are produced, which then only have to be laid for installation. It is possible to pour these plates in the prefabrication already with the filler, such as the bitumen, or you can lay the plates unausgegossen to then pour them out on site. In order to prevent leakage of the filling material on the base surface of the perpendicular material during the casting of the bitumen, there may be provided a bottom layer.

The slab according to the invention can also be configured well as a floor heating: For this purpose, it is provided that the perpendicular material has grooves on the top surface, are inserted in the heating pipes. Preferably, the material is covered before laying a floor covering on the lining base with a stable glass fiber layer, for example, such as is known from DE 20 2012 103 802 U1. The heating pipes can be used in the hot season for cooling, for example, when cold water is passed. Another possibility of a floor heating is that above the vertical corrugated and flat material is a layer of electrical conductors for heating. This can be designed so that the heating is designed for a low-voltage range, for example for 24 volts, so that the operation can be carried out directly with self-generated Soiarstrom.

The padding substructure may consist of a layer of vertical corrugated and flat material or of several paving base layers. The latter is particularly advantageous in the case of floor coverings, for example when stronger footfall sound insulation is desired. In order to apply several paving base layers, it is proposed that there be a horizontally extending intermediate layer between the paving base layers. Such an intermediate layer allows the underlying layer to have other or no filler. This results in floor coverings with the highest insulation, since such an air space allows an even stronger footfall sound insulation. In such an embodiment, the high stability of the perpendicular material is of particular advantage. In this case, even a non-poured or filled with bitumen or other material pad lining layer of vertical material is still so stable that it can be used in a heavy load area, for example in an area that is traveled by vehicles. As a result, the invention underlay can be used even in production rooms of factories.

Of course, it is also possible to use any other paving substructures, for example it is proposed, when laying heating pipes and / or electrical conductors, to arrange a ply with good heat-conducting material over the heating pipes in order to allow a uniform distribution of the heat over the ground surface. The invention will be described below with reference to the drawing

Embodiments explained. Show it 1 shows a simple embodiment of the substructure according to the invention,

Fig. 2 shows an embodiment showing a possible developments, and Fig. 3 shows an embodiment which has a plurality of paving base layers.

Fig. 1 shows a simple configuration of the substructure according to the invention, as he is laying especially under floor coverings. Of course, however, other applications, such as wall insulation possible. The simplest embodiment consists in that a lining underlay layer 2 is constructed of corrugated material 1, whereby a corrugated layer V and a planar layer 1 "alternate, ie the corrugated material 1 and the planar layer 1" run perpendicular to the base surface 4 and cover surface 5 ,

As a result, it is possible to fill in this undercoating layer 2 in a simple manner from above with bitumen as filling material 3.

Fig. 2 shows an embodiment which shows a possible development. Here, too, the basic element is the corrugated material 1 alternating with a flat layer 1 "which is filled with filling material 3, which is bitumen, for example

- Or, if, as shown in Fig. 3, a further lining underlay layer 2 follows - an intermediate layer 10 ', under which then a further lining underlay layer 2 is arranged. In order to increase the insulation even further, this base layer 2 can be configured as an unfilled layer, so that the sound insulation is increased by the air space.

For underfloor heating, the upper paving base layer 2 is provided with grooves 6 in which heating pipes 7 extend in such a way that the entire floor is designed with pipe loops. About this underbody layer 2 with the

Heating pipes 7 is a layer 11 of good heat conducting material to distribute the heat emitted from the tubes 7 evenly. In addition, a layer 9 with electrical conductors for heating is additionally applied. orders, which is suitably operated in the low voltage range, for example with solar power. An overlying fiberglass layer 8 is formed as armored fabric, and protects the structure from damage.

Finally, the desired floor covering 12 is laid over it.

Of course, the indicated lining underlay layers 2 can also be constructed in other combinations, and it would also be possible to insert further padding layers 2, such as a corrugated material 1, which is filled with other material, such as sand, and so by the heavy weight leads to a further insulation. In this case, the corrugated material 1 has the advantage that a filling with other material by the vertical arrangement of the material is much easier than in a layer structure according to the above-mentioned prior art.
