Abstract

According to the invention, a first coat of synthetic resin, which prevents detachment of asbestos fibres, is initially applied to the free surface of layers of sprayed asbestos cement. Numerous holes are then drilled which penetrate the complete asbestos layer and create a bare surface on the load-bearing sheet metal skin. Synthetic resin with an adhesive is forced into the holes. A second synthetic resin layer is then applied to the first synthetic resin layer. Durability of the synthetic resin layers is ensured by the synthetic resin forced into the holes, producing a joint of high tensile strength with the load-bearing sheet metal skin.

Description

"Verfahren zum Versiegeln von offenen Asbestschichten "Method of sealing open layers of asbestos

an Gebäudedecken" ~ ~ ~ ~= ~ ~~~ ~~ = ~ = ~ ~ ~~= ~ == = == ~=~~ == ~ In Hallen ist vielfach unter einem tragenden Deckenteil (Blechhaut) eine Schicht aus Spritz-Asbestzement von einer Dicke von 25 bis 30 cm als Feuerschutz und Wärmedämmung angebracht. Asbestfasern, die sich von der zum Raum hin freien Schicht lösen, können sesundheitsschädlich sein. on building ceilings "~ ~ ~ ~ = ~ ~~~ ~~ = ~ = ~ ~ ~~ = ~ == = == ~ = ~~ == ~ In halls there is often a layer under a load-bearing ceiling part (sheet metal skin) Made of sprayed asbestos cement with a thickness of 25 to 30 cm as fire protection and thermal insulation appropriate. Asbestos fibers that detach from the layer exposed to the room can be harmful to health.

Der Erfindung liegt die Aufgabe zugrunde eine bereits angebrachteAsbestschicht kostensparend unschädlich zu machen ohne sie zu entfernen. The invention is based on the object of an already applied asbestos layer cost-saving to render harmless without removing them.

Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Patentanspruches gelöst.This object is achieved by a method with the features of patent claim solved.

Bei einer mit diesem Verfahren behandelten Decke ist die Asbestschicht zum Raum hin derart versiegelt, daß sich keine schädlichen Asbestfasern mehr lösen können. Über die gesamte Decke sind Löcher gebohrt, mindestens ein Loch pro Quadratmeter mit Durchmessern im Bereich von 2 bis 10 mm, die einyepreßten Kunstharz mit einem Haftmittel aufnehmen. Durch den eingepreßten Kunstharz wird zwischen dem tragenden Deckenteil (Blechhaut) und den Kunstharzschichten eine Zugverbindung hergestellt, welche die statische Haltbarkeit der Kunstharzschicht gewährleistet. Das Verfahren nach der Erfindung läßt sich kurzzeitig durchführen, sodaß die Hallen bald wieder benutzt werden können. Für das Einpressen des Kunstharzes in die Löcher kann man an sich bekannte Preßköpfe verwenden. Bei Versuchen wurde mit ca. 2 bar eingepreßt. Schon nach Aufbringen der ersten Kunsthcrzschicht ist die Gefahr im wesentlichen so weit gebannt, daß die Halle wieder benutzt werden kann.A ceiling treated with this process has the asbestos layer Sealed to the room in such a way that no more harmful asbestos fibers come off can. Holes are drilled all over the ceiling, at least one hole per square meter with diameters in the range from 2 to 10 mm, the injected synthetic resin with a Pick up adhesive. The pressed-in synthetic resin is between the load-bearing The ceiling part (sheet metal skin) and the synthetic resin layers create a connection, which ensures the static durability of the synthetic resin layer. The procedure according to the invention can be carried out briefly, so that the halls soon again can be used. For pressing the synthetic resin into the holes you can use known compression heads. In tests, it was pressed in at approx. 2 bar. Even after the first layer of synthetic resin has been applied, the danger is substantial banished so far that the hall can be used again.

Gemäß der weiteren Erfindung werden beim Bohren der Löcher Bohrer verwandt, die durch zwei vorne aufgesteckte Blattfedern verlängert sind. Beim Andrücken des Bohan rers legen sich diese Blattfedern der Blechhaut an und spreizen sich, sodaß im Bereich der Blechhaut ein Raum mit einem Durchmesser entsteht, der größer als der Bohrlochdurchmesser ist, wobei in diesem Raum die 5 Blechoberfläche blank gemacht wird. Beim Einpressen des Kunstharzes wird der erweiterte Raum mit dem Kunstharz ausgefüllt. Es entsteht ein pilzförmiger Kunststoffpfropfen, der gegenüber der Blechhaut eine besonders große Haftfläche hat. Anstatt zweier Blattfedern können auch zwei Streifen aus einem glasfaserverstärkten Kunststoff, beschichtet mit Schmirgel, auf die Bohrer gesteckt werden.According to the further invention, drills are used when drilling the holes related, which are extended by two leaf springs attached to the front. When pressing of the drill, these leaf springs lie against the sheet metal skin and spread, so that a space with a larger diameter is created in the area of the sheet metal skin than the borehole diameter, in which case the 5th Sheet metal surface is made blank. When the synthetic resin is pressed in, the expanded space is also included filled with the synthetic resin. The result is a mushroom-shaped plastic stopper opposite the sheet metal skin has a particularly large adhesive surface. Instead of two leaf springs you can also two strips of a glass fiber reinforced plastic, coated with emery, be placed on the drill.
