Abstract

A process is disclosed for rehabilitating asbestos-containing roof and wall coverings. Styropor plates (2) are interlockingly laid on the asbestos-containing roof or wall coverings (5), completely insulating and sealing them. The Styropor plate (2) at the same time improves heat and acoustic insulation. Its upper side is covered with a flat finishing element (6) made for example of ceramic material. This rehabilitating process is cheaper and less harmful to the environment than dismounting the asbestos-containing coverings.

This remedial work, however, leads to an increased exposure to asbestos for the surrounding area and the people involved in the remedial work over a longer period of time. In addition, completely new roof

35 Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Sanieren von asbesthaltigen Dach- und Wandbelägen zu schaffen, das preiswert ist und mit dem eine weitere Belastung mit asbesthaltigen Materialien vermieden wird.35 The invention has for its object to provide a method for the renovation of asbestos-containing roof and wall coverings that is inexpensive and with which a further exposure to asbestos-containing materials is avoided.
Die Aufgabe wird dadurch gelöst, daß eine oder mehrere formschlüssig auf den Belag passende Styroporplatten dicht auf das Dach bzw. die Wand aufgebracht werden, wobei die dem Belag abgewandte Seite der Platte von einem flächigen Abschlußelement bedeckt ist.The object is achieved in that one or more styrofoam plates which form-fit onto the covering are applied tightly to the roof or the wall, the side of the plate facing away from the covering being covered by a flat end element.
Die asbesthaltigen Dach- und Wandbeläge weisen häufig aus Gründen einer besseren Formstabilität eine Profilform auf, die z.B. bei Dachbelägen wellenförmig verläuft.For reasons of better dimensional stability, the asbestos-containing roof and wall coverings often have a profile shape that e.g. with corrugated roof coverings.
Erfindungsgemäß wird zur Sanierung derartiger Beläge eine formschlüssig auf den Belag passende Styroporplatte verwen¬ det, deren Unterseite ebenfalls wellenförmig ausgebildet ist und die exakt in die Wellenform des Dachbelages hineinpaßt. Auf diese Weise kann die Styroporplatte dicht auf den vorhandenen Dach- bzw. Wandbelag aufgebracht werden, ohne daß die Gefahr besteht, daß asbestha tige Teilchen in die Umwelt gelangen können. Dabei kann darauf verzichtet werden, den asbesthaltigen Dachbelag zu entfernen.According to the invention, a polystyrene plate that fits the covering in a form-fitting manner is used to renovate such coverings, the underside of which is also wave-shaped and which fits exactly into the wave shape of the roof covering. In this way, the styrofoam plate can be applied tightly to the existing roof or wall covering without the risk that asbestos-containing particles can get into the environment. It is not necessary to remove the asbestos-containing roof covering.
Die dem Belag abgewandte Seite der Styroporplatte ist vorzugsweise eben ausgebildet und trägt ein flächiges Abschlußelement, das z.B. bei der Verwendung zur Dachsanie¬ rung als keramischer Belag ausgebildet sein kann, der korrosionsbeständig ist und bei entsprechender Dicke als begehbare Fläche dienen kann. Bei der Verwendung zur Sanierung von Wandbelägen kann das flächige Abschlußelement zur Aufnahme von weiteren Verkleidungselementen wie z.B. Tapeten oder dergl . dienen. Die Verwendung einer Styroporplatte mit entsprechend ausge¬ bildeter in das Dach- bzw. Wandprofil passender Unterseite ermöglicht eine völlig dichte Isolierung des asbesthaltigen Materials. Selbst geringere Unebenheiten des zu sanierenden Untergrundes oder etwa überstehende Befestigungselemente wie Schrauben und dergl. werden durch die nachgiebige Styropor¬ platte dicht umschlossen und versiegelt.The side of the styrofoam plate facing away from the covering is preferably flat and has a flat closure element which, for example when used for roof renovation, can be designed as a ceramic covering, which is corrosion-resistant and, with a corresponding thickness, can serve as a walkable surface. When used for the renovation of wall coverings, the flat end element can be used to hold further cladding elements such as wallpaper or the like. serve. The use of a styrofoam plate with a correspondingly designed underside that fits into the roof or wall profile enables completely tight insulation of the asbestos-containing material. Even less unevenness in the surface to be renovated or any protruding fastening elements such as screws and the like are tightly enclosed and sealed by the resilient styrofoam plate.
Für die Aufbringung der Styroporpl atten kann ein geeigneter Kleber verwendet werden.A suitable adhesive can be used to apply the polystyrene.
Die Styroporpl atten sind vorzugsweise aus wiederverwertetem Altstyropor hergestellt, das z.B. aus der Verpackungs¬ industrie stammt.The polystyrene is preferably made from recycled old polystyrene, which e.g. comes from the packaging industry.
Die Styroporpl atten und das Abschlußelement werden vorzugs¬ weise als Sandwichprodukt vorgefertigt, so daß beim Sanieren vor Ort außer den Verlege- und Befestigungsarbeiten keine Arbeiten mehr anfallen.The Styroporpl atten and the end element are prefabricated as a sandwich product, so that no renovation work on site except the laying and fastening work.
Die Erfindung ist in der Zeichnung beispielsweise veran¬ schaulicht und wird im nachfolgenden anhand der Zeichnung im einzelnen wie folgt beschrieben.The invention is illustrated in the drawing, for example, and is described in detail below with reference to the drawing as follows.
Das in der Zeichnung perspektivisch dargestellte Sandwich¬ element 1 besteht aus einer Styroporplatte 2 mit einer profilierten Unterseite 3 und einer ebenen Oberseite 4. Die Profilierung der Unterseite 3 entspricht in ihrer Form dem Profil eines asbesthaltigen Dachbelages 5, auf das die Styroporplatte 2 formschlüssig auflegbar ist. Auf der ebenen Oberseite 4 der Styroporplatte 2 ist ein flächiges Abschlu߬ element 6 angeordnet, das aus einer korrisions- und trittfesten Kerami schicht besteht.The sandwich element 1 shown in perspective in the drawing consists of a styrofoam plate 2 with a profiled underside 3 and a flat top 4. The shape of the underside 3 corresponds in shape to the profile of an asbestos-containing roof covering 5, onto which the styrofoam plate 2 can be placed in a form-fitting manner . On the flat top 4 of the styrofoam plate 2, a flat end element 6 is arranged, which consists of a corrosion and tread resistant ceramic layer.
Das Sandwichelement 1 wird durch Verkleben formschlüssig mit 4 dem asbesthaltigen Dachbelag 5 verbunden, so daß dieses vollständig versiegelt ist und kein asbesthaltiges Material mehr an die Umgebung gelangen kann.The sandwich element 1 is form-fitting by gluing 4 connected to the asbestos-containing roof covering 5, so that it is completely sealed and no more asbestos-containing material can get into the environment.
Das auf den Dach- bzw. Waπdbelag aufgebrachte Sandwich¬ element 1 dient nicht nur der Versiegelung des asbesthalti¬ gen Materials, sondern erhöht auch die Wärmedämmung und Schalldämmung der Wand bzw. des Daches. The load applied to the roof or sandwich Waπdbelag ¬ element 1 not only serves to seal the asbesthalti ¬ gen material but also the thermal insulation and acoustic insulation increases the wall or the roof.
