Abstract

Die Anordnung zur Entfeuchtung vertikaler Bauwerksteile soll an Hochbauten, vorzugsweise an Behältern aus Beton mit wärmegedämmter Wandung zur Anwendung kommen. Dazu sind in der Auîenwandung zwischen der Auîenwandung und der Dämmschicht oder in der Dämmschicht vertikal und diagonal verlaufende Faserbündel oder andere Fasergebilde zu einem Feuchteleitsystem angeordnet, welches vollständig oder teilweise in eine frostfreie Sammelleitung mündet. Die diagonal verlaufenden Faserbündel nehmen die anfallende Feuchte auf und führen sie dem vertikal verlaufenden Faserbündel zu, in denen die Feuchte frostfrei aus dem Bauwerksteil entweder direkt ins Erdreich oder über Sammelleitung, die an einer bekannten Entwässerungsleitung angeschlossen ist, abgeleitet wird. Bei gleicher Anordnung anderer feuchteleitender Fasergebilde wird der gleiche Effekt erzielt. Das Prinzip wird in einer Zeichnung dargestellt. Figur{Entfeuchtung vertikaler Bauwerksteile, wärmegedämmte Wandung, vertikal und diagonal verlaufende Faserbündel, Feuchteleitsystem, frostfreie Sammelleitung}The arrangement for dehumidifying vertical building parts should be used on buildings, preferably on containers made of concrete with a thermally insulated wall. For this purpose, in the outer wall between the outer wall and the insulating layer or in the insulating layer, vertically and diagonally extending fiber bundles or other fiber structures are arranged to form a moisture control system which opens completely or partially into a frost-free collecting line. The diagonal fiber bundles absorb the resulting moisture and lead them to the vertically extending fiber bundle, in which the moisture is frost-free from the building part either directly into the ground or via manifold, which is connected to a known drainage line, derived. With the same arrangement of other moisture-conducting fiber structures, the same effect is achieved. The principle is shown in a drawing.

Description

Die diagonal verlaufenden Faserbündel nehmen die Flächenfeuchte auf und führen diese den vertikal verlaufenden Faserbündeln zu. Von hier mündet das Feuchteleitsystem über eine Sammelleitung oder ohne Sammelleitung frostfrei in ein bekanntes Entwässerungssystem.The diagonal fiber bundles absorb the surface moisture and feed it to the vertical fiber bundles. From here, the moisture management system discharges frost-free into a well-known drainage system via a collecting line or without a manifold.

Der Feuchtetransport in den Faserbündeln oder den Fasergebilden erfolgt unter Schwerkraftwirkung und wird infolge der geringen Kapillarkräfte nicht behindert.The moisture transport in the fiber bundles or the fiber structures is under gravity and is not hindered due to the low capillary forces.

embodiment

Die Erfindung soll nachstehend an einem Ausführungsbeispiel erläutert werden. Die dazugehörige Zeichnung zeigt die Isometrie einer Behälterwandung mit eingebautem Feuchteleitsystem.The invention will be explained below using an exemplary embodiment. The accompanying drawing shows the isometry of a container wall with built-in humidity control system.

Auf der äußeren Oberfläche eines Flüssigkeitsbehälters aus Spannbeton werden diagonal verlaufende Faserbündel 2 aus z. B.On the outer surface of a liquid container made of prestressed concrete diagonal fiber bundles 2 are made of z. B.

Sekundärrohstoffen, wie Kemafilstrick, mit vertikalen Faserbündeln 3 aus dem gleichen Material so angeordnet, daß sie sich unter einem Winkel von beispielsweise 45° in einem gleichmäßigen Abstand zueinander kreuzen. Zwischen der durch die Wetterschutzschicht.7 bekleideten Dämmschicht 5 aus Mineralwolle und der Außenwandung 1 des Behälters mit dem darin befindlichen Feuchteleitsystem ist eine Trennschicht 4 aus PVC-Weichfolie angeordnet. Diese Trennschicht 4 kann bei Anwendung geeigneter Dämmstoffe, wie PUR-Hartschaum, entfallen. Im unteren Bereich der gedämmten Fläche münden die vertikalen Faserbündel 3 in eine Sammelleitung 6 aus PVC-Rohr. Die Sammelleitung 6 aus PVC-Rohr wird frostfrei mittels bekannter technischer Lösungen entwässert und mündet in eine herkömmliche Entwässerungseinrichtung.Secondary raw materials, such as Kemafil knit, with vertical fiber bundles 3 of the same material arranged so that they intersect at an angle of for example 45 ° at a uniform distance from each other. Between the insulation layer 5 covered by the Wetterschutzschicht.7 made of mineral wool and the outer wall 1 of the container with the moisture control system therein, a release layer 4 is arranged PVC soft film. This release layer 4 can be omitted when using suitable insulation materials, such as rigid polyurethane foam. In the lower part of the insulated surface, the vertical fiber bundles 3 open into a manifold 6 made of PVC pipe. The manifold 6 made of PVC pipe is dehydrated frost-free by means of known technical solutions and flows into a conventional dewatering device.

Die Erfindung soll im Bauwesen bei der vertikalen Entfeuchtung von Hochbauten, vorwiegend von Behältern aus Beton, zur Anwendung kommen.The invention is intended to be used in the construction industry in the vertical dehumidification of buildings, mainly concrete tanks.

Der spezifische Vorteil der Erfindung liegt darin, daß das bisher notwendige material- und zeitaufwendige Aufbringen der wasserundurchlässigen Schicht wegfällt. Darüber hinaus wird die Dämmschicht nicht mehr zerstört bzw. die Dämmwirkung durch Verhindern des Einfrierens des Feuchtestroms oder durch Wegfall des konvektiven Wärmetransports wird erhöht.The specific advantage of the invention is that the previously necessary material and time consuming application of the water-impermeable layer is eliminated. In addition, the insulating layer is no longer destroyed or the insulating effect by preventing the freezing of the moisture flow or by eliminating the convective heat transport is increased.

Field of application of the invention

The invention is intended to be used in the vertical dehumidification of buildings, preferably of heat-insulated concrete containers.

Characteristic of the known state of the art

All known insulation materials are severely limited in constant humidity exposure in their thermal insulation function and life. Therefore insulating materials are always installed dry and largely protected against moisture in the use state. The inevitable during building use, usually only low humidity, can diffuse out of the insulation during the warm season again. If this moisture enrichment exceeds a certain limit, additional equipment or measures must support the desiccation process. It is known that in order to improve the drying behavior of the insulating materials, they are equipped with diffusion windows (DE-OS 3103242 A1). It is also known that corresponding insulating, partially water-conducting, are formed (DE-OS 3504873 A1)., These solutions have the disadvantage that in an application on the outside of building parts, the desired effect in the cold season, due to icing no longer achieved and the insulation is destroyed by the increase in moisture.

Furthermore, it is known that insulating panels made of foamed plastic with vertical ventilation ducts for external insulation of basement walls are used (DE-OS 3113807 A1).

These and other similar solutions have the disadvantage, inter alia, that their insulating effect is greatly reduced due to convective heat transport and the prefabricated plates are very expensive to manufacture. Thermally insulated concrete containers are therefore provided on the inside with an absolutely water-impermeable layer, since even a so-called "waterproof concrete" can not prevent the passage of a moisture accumulation in the order of a few hundred ml / md ^2. The application of this impermeable layer is very material and Costly, adversely affects the construction time, and the construction cost is increased.

Object of the invention

The aim of the invention is to find a solution which, with the elimination of the water-impermeable layer, ensures permanent dehumidification, is cheaper to manufacture and beyond the risk of damage in the insulating layer excludes and minimizes heat loss.

Explanation of the essence of the invention

The object of the invention is to omit the waterproof layer in the manufacture of particular concrete containers and to develop a solution for permanently dehumidifying vertical surfaces of buildings with not absolutely watertight, thermally insulated wall, which eliminates the shortcomings of the known technical solutions. According to the invention the object is achieved in that vertically and diagonally at a certain distance from one another running, water-conductive fiber bundles, without or with low capillary action, are arranged in the region of the surface to be dehumidified. They are connected to each other directly or by means of other water-conductive fiber structures. With sufficient moisture conductivity of these fiber structures, the vertical fiber bundles can be omitted. In addition to the fiber bundles, only other water-conductive Fasergebiide can be used. The moisture control system is arranged in the interface between the outer wall and the insulating material or a separating layer which protects the insulating material as required. The arrangement can also take place in the outer wall or in the insulating layer. ,
