Description
Die Erfindung betrifft ein Verfahren zur Sanierung einer Asbestzement-Dacheindeckung, bei dem auf die Asbestzement-Dacheindeckung eine Dämmschicht aufgelegt wird und darüber eine neue Eindeckung angeordnet wird. Insbesondere betrifft die Erfindung eine Well-Asbestzement-DacheindeckungThe invention relates to a method for renovating an asbestos-cement roof covering, where on the asbestos cement roof covering Insulation layer is put on and a new covering arranged becomes. In particular, the invention relates to a corrugated asbestos cement roof covering
Bei der Sanierung von Well-Asbestzement-Dacheindeckungen treten zwei Hauptprobleme auf. Die Eindeckungen müssen vorher auf ihre noch bestehende Haltbarkeit durch Auszugsversuche überprüft werden und dürfen nur mit Laufbohlen betreten werden. Zweitens darf bei der Sanierung kein Asbeststaub frei werden, da dieser sehr stark krebserregend ist.When renovating corrugated asbestos cement roof coverings, there are two Main problems. The covers must be on theirs beforehand existing durability can be checked by pulling out and may only be entered with walking boards. Second, the Remediation does not release asbestos dust because it is very carcinogenic is.
Es wurden deshalb Halterungen für die neue Dacheindeckung vorgeschlagen, die an der vorhandenen Verschraubung der Asbestzementplatten befestigt werden. Hierzu ist jedoch erforderlich, daß die Schrauben noch voll funktionsfähig sind und in der Praxis hat sich gezeigt, daß die vorhandenen Schrauben häufig so verwittert sind, daß ein Anbringen von Halterungen äußerst schwierig ist. Therefore there were brackets for the new roof covering proposed to the existing screw connection of the Asbestos cement panels are attached. However, this requires that the screws are still fully functional and has been in practice shown that the existing screws are often so weathered that a Attaching brackets is extremely difficult.
Es wurde auch vorgeschlagen, in die Asbestzement-Dacheindeckung Löcher zu bohren, um spezielle Halterungen auf der vorhandenen Dacheindeckung anzubringen. Beim Durchbohren der Asbestzement-Dacheindeckung entsteht jedoch feiner Staub und es ist deshalb in den meisten Gebieten verboten, wie z.B. in Deutschland durch die TRGS 519, Asbestplatten anzubohren. Auch Versuche mit Absaugeinrichtungen führten in der Praxis zu keinen guten Ergebnissen, da das Anbringen der Absaugeinrichtungen an den meist gewellten Asbestzementplatten sehr schwierig ist und somit zwischen der Absaugeinrichtung und der Asbestzementplatte Feinststäube austreten.It has also been suggested in the asbestos cement roof covering Drill holes to fit special mounts on the existing one Install roof covering. When drilling through the asbestos cement roof covering however, fine dust arises and it is therefore in the prohibited in most areas, e.g. in Germany by TRGS 519, Drill asbestos sheets. Tests with suction devices also led in practice to no good results, since the attachment of the Suction devices on the mostly corrugated asbestos cement panels very much is difficult and thus between the suction device and the Escape asbestos cement sheet of fine dust.
Der Erfindung liegt daher die Aufgabe zugrunde, ein neues Verfahren zur Sanierung einer Asbestzement-Dacheindeckung vorzuschlagen, das auf einfache Art und Weise die Anbringung einer neuen Dacheindeckung oberhalb der Asbestzement-Dacheindeckung erlaubt.The invention is therefore based on the object of a new method for Propose renovation of an asbestos cement roof covering that on simple way of installing a new roof covering allowed above the asbestos cement roof covering.
Diese Aufgabe wird dadurch gelöst, daß auf der auf die Asbestzement-Dacheindeckung aufgelegten Dämmschicht mindestens ein Stahlprofil angeordnet wird, durch das Stahlprofil, die Dämmschicht und die Asbestzement-Dacheindeckung Löcher gebohrt werden und das Stahlprofil mit sich durch die Löcher erstreckenden Verbindungselementen an der Asbestzement-Dacheindeckung befestigt wird. Die Löcher im Stahlprofil können dabei auch schon vorgebohrt sein. This object is achieved in that on the asbestos cement roof covering applied insulation layer at least one steel profile is arranged by the steel profile, the insulation layer and the Asbestos cement roof covering holes are drilled and the steel profile with connecting elements extending through the holes on the Asbestos cement roof covering is attached. The holes in the steel profile can also be pre-drilled.
Überraschenderweise hat sich gezeigt, daß beim Bohren durch das Stahlprofil, die Dämmschicht und die Asbestzement-Dacheindeckung Bohrstaub der im Bereich der Asbestzement-Dacheindeckung entsteht, sich in der Dämmschicht verfängt und oberhalb des Stahlprofils fast überhaupt kein Staub mehr auftritt. Die glatte Oberfläche des Stahlprofils erlaubt es aber darüberhinaus, eine Abdichteinrichtung abdichtend anzusetzen, um somit möglicherweise austretenden Staub sicher abzusaugen. Außerdem erleichtert die glatte Oberfläche des Stahlprofils ein Abwischen von aus der Bohrung ausgetretenen Fasern.Surprisingly, it has been shown that when drilling through the Steel profile, the insulation layer and the asbestos cement roof covering Drilling dust that arises in the area of asbestos cement roof covering, itself caught in the insulation layer and almost at all above the steel profile no more dust occurs. The smooth surface of the steel profile allows it but moreover to set a sealing device to seal thus safely extract any escaping dust. Furthermore The smooth surface of the steel profile makes it easier to wipe it off Bore leaked fibers.
Um eine hohe Sicherheit gegen austretende Fasern zu erzielen, wird daher vorgeschlagen, daß beim Bohren der Löcher durch eine bekannte Absaugvorrichtung oberhalb des Stahlprofils Staub abgesaugt wird.In order to achieve a high level of security against escaping fibers, therefore suggested that when drilling the holes through a known Suction device above the steel profile dust is extracted.
Sofern beim Entfernen des Bohrers optisch noch Staubpartikel wahrgenommen werden können oder auch einfach aus Sicherheitsgründen wird vorgeschlagen, nach dem Bohren der Löcher das Stahlblech im Bereich der Löcher feucht abzuwischen. Wegen der glatten Oberfläche des Stahlblechs kann mit einem feuchten Tuch oder Schwamm der Bereich um das gebohrte Loch leicht durch Abwischen und Absaugen gesäubert werden.If there is still dust particles when the drill is removed can be perceived or simply for security reasons It is suggested that after drilling the holes in the steel sheet Wipe the area of the holes with a damp cloth. Because of the smooth surface of the Sheet steel can be used to wipe the area with a damp cloth or sponge the drilled hole is easily cleaned by wiping and vacuuming become.
Das erfindungsgemäße Verfahren ermöglicht es somit, Asbestzement-Dacheindeckungen von der Seite auf die die Dämmschicht aufgelegt ist, anzubohren und die Kombination von faseriger Dämmschicht und glattem Stahlprofil bewirkt einerseits ein sich Verfangen von Fasern im Bereich der Dämmschicht und andererseits eine gute Abdichtung im Ansatzbereich des Bohrers.The method according to the invention thus enables asbestos-cement roof coverings from the side on which the insulation layer is placed, to drill and the combination of fibrous insulation layer and smooth Steel profile on the one hand causes fibers to get caught in the area of the Insulation layer and on the other hand a good seal in the attachment area of the Drill.
Das erfindungsgemäße Verfahren wurde in der Praxis erprobt und von Umweltbehörden genehmigt, die extrem hohe Anforderungen an die Arbeitssicherheit fuhr das Dachdeckerpersonal stellen. Es wurde nicht nur der Grenzwert von 15.000 Fasern/m3 eingehalten, sondern es konnten grundsätzlich keine Fasern bei der Messung festgestellt werden.The method according to the invention has been tested in practice and approved by environmental authorities, which the roofing staff made extremely high demands on occupational safety. Not only was the limit value of 15,000 fibers / m 3 adhered to, but in principle no fibers were found during the measurement.
Da in manchen Fällen nicht ausgeschlossen werden kann, daß unter der Asbestzement-Dacheindeckung durch das Bohren Staub austritt und dieser in den Freiraum des Gebäudes gelangt, wird vorgeschlagen, daß unter der Asbestzement-Dacheindeckung eine weitere Schicht angeordnet wird. In vielen Fällen ist eine derartige Schicht als Dämmplatte schon vorhanden, so daß keine Fasern in das Innere des Gebäudes gelangen.Since in some cases it cannot be ruled out that under the Asbestos cement roof covering by drilling dust escapes and this in the open space of the building, it is proposed that under the Asbestos cement roof covering another layer is arranged. In In many cases, such a layer is already available as an insulation board, so that no fibers get inside the building.
Als weitere Schicht kann eine Dämmschicht verwendet werden. Da oberhalb der Asbestzement-Dacheindeckung jedoch schon eine Dämmschicht aufgebracht ist, reicht auch eine Folie als Schutzschicht unterhalb der Asbestzement-Dacheindeckung. An insulation layer can be used as a further layer. There but already one above the asbestos cement roof covering Insulation layer is applied, a film is sufficient as a protective layer below the asbestos cement roof covering.
Eine einfache Arbeitsweise wird dadurch erzielt, daß die oberhalb der Asbestzement-Dacheindeckung angeordnete Dämmschicht eine trittfeste Faserdämmplatte ist. Nach Auflegen der Dämmschicht ist der gesamte Dachbereich begehbar und es besteht nicht mehr die Gefahr, daß durch Belastung der Asbestzement-Dacheindeckung die Eindeckung bricht oder Löcher entstehen. Außerdem wird Abrieb an der Asbestzement-Dacheindeckung während des Sanierungsverfahrens durch die aufgelegte Dämmschicht vermieden. Als Dämmschicht oberhalb der Asbestzement-Dacheindeckung können auch andere Schichten aus Faserdämmplatten oder Schichten aus Styropur und/oder Polyurethan-Schaum verwendet werden.A simple way of working is achieved in that the above the Asbestos-cement roof covering arranged an impact-resistant Is fiber insulation board. After laying on the insulation layer is the whole Roof area can be walked on and there is no longer a risk that Loading the asbestos cement roof covering will break or Holes arise. There will also be abrasion on the asbestos cement roof covering during the reorganization process by the Insulation layer avoided. As an insulation layer above the asbestos cement roof covering can also other layers of fiber insulation boards or Layers of polystyrene and / or polyurethane foam can be used.
Vorteilhaft ist es, wenn die Stahlprofile U-förmig ausgebildet sind. Dies erlaubt es, die U-förmigen Schenkel der Stahlprofile in der Dämmschicht zu verankern. Dadurch wird eine einfache Positionierung der Stahlprofile erreicht und ein Verrutschen der Profile verhindert.It is advantageous if the steel profiles are U-shaped. This allows the U-shaped legs of the steel profiles in the insulation layer to anchor. This makes it easy to position the steel profiles reached and prevents the profiles from slipping.
Insbesondere bei der Verwendung trittfester Dämmplatten ist es vorteilhaft, wenn in die Dämmschicht entsprechend den Stahlprofilen Nuten eingefräst werden. In die eingefrästen Nuten sind anschließend die Stahlprofile leicht einlegbar, so daß eine sichere Verbindung zwischen Stahlprofil und Dämmschicht entsteht.Especially when using solid insulation boards, it is advantageous if grooves are milled into the insulation layer in accordance with the steel profiles become. The steel profiles are then light in the milled grooves insertable, so that a secure connection between steel profile and Insulation layer is created.
Ein bevorzugtes Ausführungbeispiel der Erfindung sieht vor, daß die Verbindungselemente Nieten - vorzugsweise Presslaschnieten - sind. Nieten lassen sich auf einfache Art und Weise in den Löchern anbringen und erlauben eine schnelle Verbindung von Asbest-Dacheindeckung, Dämmschicht und Stahlprofil. Diese Nieten werden vorzugsweise so angeordnet, daß der Kopf der Niete im Bereich des Stahlprofils liegt und das beim Anziehen der Niete sich verbreiternde Ende unterhalb der Asbestzement-Dacheindeckung. Bei Asbestzement-Dacheindeckungen mit Wellenprofil kann das sich verbreiternde Ende der Nietejeweils im Bereich der Wellen-Hochsicke angeordnet werden. Dadurch entsteht ein besonders kompakter Aufbau des Daches.A preferred embodiment of the invention provides that the Connecting elements are rivets - preferably press rivets. Rivets can be easily attached in the holes and allow a quick connection of asbestos roofing, Insulation layer and steel profile. These rivets are preferably like this arranged that the head of the rivet lies in the area of the steel profile and the widening end when tightening the rivet below the Asbestos cement roof covering. With asbestos cement roof coverings with Wave profile can be the widening end of the rivet each in the area the corrugated high corrugation. This creates a special compact construction of the roof.
Auf die Stahlprofile kann eine beliebige Eindeckung aufgebracht werden. Beispielsweise ist auch das Aufbringen einer Folie möglich. Eine besonders widerstandsfähige, lange haltbare und einfach anzubringende Dacheindeckung entsteht dadurch, daß als Neueindeckung ein Trapezblech verwendet wird.Any covering can be applied to the steel profiles. For example, it is also possible to apply a film. A special one tough, long lasting and easy to install Roofing is created by using a trapezoidal sheet as the new covering is used.

Das vor Anwendung des erfindungsgemäßen Verfahrens vorhandene
Asbestzement-Dach besteht aus einem Tragaufbau 1, von dem zwei Träger
2 und 3 gezeigt sind. Auf diese Träger ist eine Isolationsschicht 4
aufgelegt, auf der eine wellenförmige Asbestzement-Dacheindeckung 5
befestigt ist.The one before using the method according to the invention
Asbestos cement roof consists of a support structure 1, of which two
Zur Sanierung dieser Dacheindeckung 5 wird zunächst die Eternitwelle mit
einem weichen oder wellenförmigen Dämmaterial 6 (Traufe und First ca.
1m) abgedämmt. Dieses Dämmaterial 6 liegt in den Wellentälern und sorgt
für eine Schließung der Profilwelle auf der Asbestzement-Dacheindeckung
5, auf die eine Dammsperre 7 aufgelegt wird. Auf diese Dammsperre 7
werden feste Wärmedärmmplatten 8 mit beispielsweise einer Stärke von 60 -
180 mm aufgelegt, so daß das Dach im Bereich der aufgelegten
Wärmedämmplatten 8 begehbar wird.To renovate this roof covering 5, the Eternit wave is first used
a soft or wavy insulation material 6 (eaves and ridge approx.
1m) insulated. This insulating
In diese Wärmedämmplatten 8 werden in einem Abstand von etwa 10 cm
zueinander verlaufende, etwa 5 cm tiefe Nuten 9 eingefräst, die sich im
wesentlichen über die gesamte Dachfläche erstrecken.In this
In diese Nuten 9 werden U-förmige Stahlprofile 10 so eingesetzt, daß die
Schenkel der U-förmigen Stahlprofile 10 sich in die Nuten 9 erstrecken. In these grooves 9, U-shaped
Die Nuten 9 und die Profile 10 werden so auf den Wärmedämmplatten 8
angeordnet, daß auf den Stahlprofilen 10 anschließend leicht eine weitere
Dacheindeckung 14 befestigbar ist. Art, Lage und Anzahl der Profile wird
hierbei entsprechend der zuvor berechneten Statik festgelegt.The grooves 9 and the
Anschließend wird mit einer Bohrmaschine mit integrierter Saug- und
Staubsammeleinrichtung zunächst durch das Profil 10, dann durch die feste
Dämmplatte 8 und die Dammsperre 7 und schließlich durch die
Asbestzement-Dacheindeckung 5 ein Loch gebohrt. Das Loch durch das
Profil 10 wird dabei zunächst vorgebohrt. Die Eindringtiefe wird beim
Bohren mittels eines Anschlages so begrenzt, daß die unter der
Asbestzement-Dacheindeckung 5 liegende Isolationsschicht 4 nicht
beschädigt wird. Während des Bohrens wird kontinuierlich im Bereich des
Bohrers Staub abgesaugt und in einem Filter der Kategorie K 1, nach
TRGS 519 abgeschieden. Die glatte Basisfläche des U-förmigen Profils 10
erlaubt es dabei, abdichtend die Saugeinrichtung anzulegen, so daß kein
Staub während des Saugens austritt. Eine Schutzausrüstung für die Arbeiter
ist somit nicht erforderlich.Then with a drill with integrated suction and
Dust collecting device first through the
Nach dem Bohrvorgang wird der Bohrer herausgezogen und
möglicherweise dabei auf das Profil fallende Staubpartikel werden mit
einem feuchten Lappen abgewischt. Danach wird eine Niete 11 zunächst
durch das Profil 10, dann durch die Wärmedammplatte 8 und schließlich
durch die Asbestzement-Dacheindeckung 5 in dem gebohrten Loch geführt
und so angezogen, daß sich unterhalb der Asbestzement-Dacheindeckung
5 das Nietenende 12 verspreizt und der Nietenkopf 13 fest am Profil 10
anliegt. Die Position der Nieten 11 wird vorzugsweise so festgelegt, daß
das Nietenende 12 jeweils in der Wellenhochsicke der Asbestzement-Dacheindeckung
5 angeordnet ist.After the drilling process, the drill is pulled out and
any dust particles falling on the profile are removed
wiped with a damp cloth. Then a
