Description

· · · · · · · · · · · · · · · · · · · · · ·

The invention relates to a method for rehabilitating and / or erecting a building part, preferably basement, in particular Erdgewölbekeller in which a masonry at least forms parts of the walls and the ceiling, said building part outside the masonry adjacent material, in particular earth material, optionally removed and stored, the masonry is optionally cleaned, spacers are arranged to form a ventilation channel building outside the masonry and at least one ventilation duct is arranged, which leads from the ventilation duct to the outside of the building part, in particular above the earth level.

In addition, the invention relates to a building part.

Approximately In the 18th century, for example, cellars in Burgenland, in particular earth-vaulted cellars, were built which were originally intended for the production and / or storage of wine. Such basements have walls and, in some cases, sandstone ceilings, where the floor is a soil. The problem with such cellars is that they are moist.

Meanwhile, such basements, unless they are empty because of the high humidity, used as decorative showrooms for storage and / or tasting of wine. The problem is that mold regularly appears on the sandstone.

To counteract the problems mentioned, it is known to remove the existing soil, to apply drainage layers, to install screed, waterproofing, e.g. To attach foils, to the floor as well as to the walls and to ventilate the basement. However, it has been shown that despite ventilation and despite sealing it still comes to mold on the sandstone. Mechanical sealing behind the sandstone is very expensive and expensive, in which case there is still a lot of residual moisture in the masonry, which can not escape. Therefore, the sandstone is cleaned regularly to the mold to 2/18

···· · ♦ > ·· 2 · remove, which does not solve the problem of mold remaining on the wall and ceiling.

It is also known to use dehumidifiers in such basements. The disadvantage here is that dehumidifiers are expensive to buy and / or rent and often run over a long period of time, causing exhaust emissions are caused. In addition, dehumidifiers, even if used over a long period of time, are only one-time dehumidification. If the moisture in the masonry increases after the dehumidifier has been removed, the problems described above reoccur.

From DE 101 57 877 Al a method for building exterior side providing a moisture barrier on a basement wall is known in which a ventilation channel is formed, which is in communication with the outer environment of the basement and allows evacuation of humid air to dry the basement wall. The ventilation duct runs vertically parallel to the basement wall, so that substantially no weight forces of overlying floors or of overlying soil on the surface of the ventilation duct act. The disadvantage here is that this method does not allow dehumidification of a basement ceiling, as it can not be applied to a basement ceiling for static reasons.

The invention is based on the object to provide a building part and a method of the type mentioned, with which disadvantages of the prior art can be avoided. 3.18

Preferred and advantageous embodiments of the method according to the invention are the subject of the dependent claims.

According to the invention it is provided that arranged at the opposite end of the masonry the spacer a dimensionally stable support layer, in particular fixed, is. With the method according to the invention a durable dehumidification of walls and ceiling of a building part according to the invention is advantageously achieved, the problem that molds on the walls and ceiling, is corrected and exhaust emissions are avoided. In addition, it is advantageously ensured that the rear ventilation channel remains intact, even if large weight forces act on the base layer, for example by above arranged Erdmaterial or even if workers and / or Baumschinen during renovation or building of the building part of the invention on the support layer above the building part ceiling ,

In particular, in the Erdgewölbekeller mentioned in the introduction, the problem is solved in addition that now labels of wine bottles no longer solve during storage. Moreover, it is now also possible without hesitation, for example. keep a wine tasting to use wood furniture in the basement. So far, such furniture could not be left in the basement but would have to be stored somewhere else and transported on an occasion extra to the basement and placed there temporarily.

In a preferred embodiment of the invention, it is provided that a base layer serving as a moisture barrier is used as the base layer. In such an embodiment 4/18 ···· ··· 4 *

In a further preferred embodiment it can be provided that a seal, in particular a heat-insulating and / or water-repellent seal, is disposed on the side of the support layer opposite the rear ventilation duct. Thus, the safety is increased again before re-mold. In the context of the invention, a film and / or a mounting foam, in particular a PU foam, can be used as a seal.

In particular, when a grating is used as the support layer and a mounting foam is used as the seal, it is advantageous if a support layer for the seal, for example a nonwoven layer, for example, between the seal and the stable support layer. a Geotex fleece, is arranged.

In the context of the invention, supports or supports, in particular I-beams, can be used as spacers which, depending on the static requirements, can be made of plastic or galvanized. The spacers can be placed directly on the masonry or on an intermediate layer, for example a concrete layer, to distribute the point load of the weight. It is particularly advantageous if spacers are fastened to the masonry, in particular screwed and / or concreted.

After the formation of a Hinterlüftunskanals on the walls and on the ceiling can be provided in the invention that Gebäudeteilaußenseitig previously removed material and / or corresponding material, in particular earth material, is arranged on the stable support layer or the seal.

In a particularly preferred embodiment of the invention it can be provided that at least one ventilation duct is arranged in the masonry, which leads from the building part inside to the rear ventilation duct. This ensures that moist air can escape from the building interior through the ventilation duct to the building exterior environment. Alternatively or additionally 5/18

For this purpose, it can be provided that at least one ventilation duct is arranged, which leads from the building part interior to the outside environment of the building part, in particular above the earth level. A combination of these features is particularly advantageous since, as a whole, a " chimney effect " is achieved.

So far, it was only known for airing to connect the building interior directly with the building exterior environment. In the context of the invention, it is now additionally possible to produce a connection from the exterior of the building through the interior of the building through the ventilation duct back to the building exterior environment, whereby a particularly good ventilation and removal of moisture to the building exterior environment is realized.

In the context of the invention, it can further be provided that a drainage layer is arranged outside of the building part in the area of the lower end of the support layer serving as moisture barrier or the seal. Thus, it is advantageously achieved that water draining from the base layer or from the drain is purposefully discharged.

The invention can find application not only in Erdgewölbekellern, but in all parts of the building in which the walls and the ceiling rehabilitated and / or built. The process according to the invention is particularly advantageous, in particular, for renovating earthenware cellars.

In the context of the invention, the term " refurbishment " also the drying of building parts are understood. The invention can be used in principle for drying building parts, such as masonry, wall, ceilings, even in floods.
