Description
Die Erfindung betrifft einen Abdichtungsaufbau, insbesondere für befahrbare Flächen auf Parkdecks oder Hofkellerdecken, mit einer Rohbetondecke, mindestens einer Schicht aus bituminösen Dichtungsbahnen, einer Dämmschicht und einer Fahr- und Verschleißschicht.The invention relates to a sealing structure, in particular for passable areas Parking decks or courtyard cellar ceilings, with a raw concrete ceiling, at least one layer of bituminous Sealing membranes, an insulation layer and a driving and wear layer.
Ein derartiger, allgemein bekannter Abdichtungsaufbau kommt insbesondere dann zur Anwendung, wenn sich darunter ein beheizter und daher gegen Wärmeverluste möglichst zu schützender Raum befindet. Nach dem Stand der Technik besteht ein solcher Abdichtungsaufbau aus folgenden einzelnen Schichten:Such a generally known sealing structure is used in particular when if there is a heated and therefore against heat loss as possible protective room. Such a sealing structure exists according to the prior art from the following individual layers:
Auf die Rohbetondecke wird als Grundierung ein Bitumenhaftgrund aufgebracht, auf den wiederum eine Schicht aus bituminösen Dichtungsbahnen aufgebracht wird, die eine Dampfsperrschicht bildet, um zu verhindern, daß Feuchtigkeit aus der Rohbetondecke in die weiter oberhalb gelegenen Schichten des Dichtungsaufbaus eindringen kann.A bitumen primer is applied as a primer to the raw concrete ceiling in turn, a layer of bituminous geomembranes is applied, which is a vapor barrier layer forms in order to prevent moisture from the raw concrete ceiling in the further can penetrate layers of the seal structure located above.
Oberhalb der Dampfsperrschicht befindet sich eine Dämmschicht, die in der Regel aus druckfesten Schaumglasplatten oder extrudierten Polystyrolplatten besteht. Oberhalb dieser Dämmschicht ist die eigentliche Abdichtung gegen ein Eindringen von Feuchtigkeit von oben angeordnet. Die Abdichtung besteht aus einer unteren Ausgleichsschicht aus Bitumendachbahnen. Darüber befindet sich eine Schicht aus mehrlagigen bitominösen Dichtungsbahnen, die schließlich noch mit einem Deckanstrich aus einem Bitumenmaterial versehen wird.There is an insulation layer above the vapor barrier layer, which is usually made of pressure-resistant Foam glass sheets or extruded polystyrene sheets. Above this insulation layer is the actual seal against the ingress of moisture from above. The waterproofing consists of a lower leveling layer made of bitumen roofing membranes. There is a layer of multi-layer bitominous geomembranes above it finally it is provided with a top coat of bitumen material.
Auf den Deckanstrich wird eine Trennlage aus einer Polyethylenfolie aufgelegt, auf die beispielsweise Ortbetonplatten gegossen werden können. Alternativ zu einer vollflächigen Verlegung von Ortbetonplatten ist es auch üblich, die Fahrgassen mit Ortbetonplatten zu versehen und die Stellplatzflächen mit einem Verbundsteinpflaster zu belegen. Unterhalb des Verbundsteinpflasters wird eine Bettungsschicht aus Splitt angeordnet. Alternativ hierzu ist es auch möglich, Betonfertigteilplatten auf geeigneten Stelzlagern anzuordnen.A separating layer made of a polyethylene film is placed on the top coat, for example In-situ concrete slabs can be cast. As an alternative to full-surface installation For in-situ concrete slabs, it is also common to provide the tramlines with in-situ concrete slabs and to cover the parking spaces with a composite stone paving. Below the composite stone paving a bedding layer of chippings is placed. Alternatively, it is possible to arrange precast concrete slabs on suitable pedestals.
Als nachteilig tritt bei dem bekannten Dichtungsaufbau in Erscheinung, daß vornehmlich im Bereich der Überlappungsnähte der bitominösen Dichtlage Undichtigkeiten auftreten. Außerdem wird durch die Überlappungsnähte der Dichtungsbahnen ein vollständiges Abfließen des Niederschlagswassers zu den Abläufen verhindert. Des weiteren ist es aufwendig, Neigungen relativ zu der Rohbetondecke mit Hilfe der Dämmschicht zu erzeugen, um somit ein kontrolliertes Abfließen des Niederschlagswassers auf der bituminösen Dichtlage zu erreichen. The disadvantage of the known seal structure is that primarily in Area of the overlapping seams of the bitominous sealing layer, leaks occur. Moreover is a complete drainage of the Rainwater to the drains prevented. Furthermore, it is expensive, inclinations relative to the raw concrete ceiling with the help of the insulation layer in order to create a controlled To drain the rainwater on the bituminous sealing layer.
Ein Nachteil besteht des weiteren darin, daß eine schadensfreie Nutzung der abzudichtenden Flächen, beispielsweise mittels Gabelstaplern oder anderen Fahrzeugen, erst nach Aufbringen der Fahr- und Verschleißschicht möglich ist. Das heißt, erst nach vollständiger Fertigstellung des bekannten Abdichtungsaufbaus ist eine vollwertige Nutzung der damit versehenen Flächen möglich. Dies führt in aller Regel zu einer sehr unerwünschten Behinderung der sich an die Abdichtung anschließenden oder parallel hierzu ausführbaren Nachfolgegewerke.Another disadvantage is that damage-free use of the seals to be sealed Surfaces, for example using forklifts or other vehicles, only after application the driving and wear layer is possible. That means, only after complete completion the known sealing structure is a full use of the surfaces provided possible. This usually leads to a very undesirable disability subsequent works that can be sealed or executed in parallel to this.
Der Erfindung liegt die Aufgabe zugrunde, einen Abdichtungsaufbau insbesondere für befahrbare Flächen auf Parkdecks oder Hofkellerdecken vorzuschlagen, mit dem sich trotz einfacher Herstellbarkeit eine hohe Gewähr für die dauerhafte Dichtigkeit ergibt und der bereits nach einer teilweisen Fertigstellung befahrbar ist, ohne daß die Gefahr einer Beschädigung hierdurch besteht.The invention has for its object a sealing structure especially for vehicles Propose areas on parking decks or courtyard cellar ceilings, with which, despite being easier Producibility gives a high guarantee of permanent tightness and that already after partial completion it can be driven on without the risk of damage hereby exists.
Ausgehend von einem Abdichtungsaufbau der eingangs beschriebenen Art, wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die Dämmschicht oberhalb einer Gußasphaltschicht und diese oberhalb einer Schicht aus bituminösen Dichtungsbahnen angeordnet ist.Starting from a sealing structure of the type described above, this task solved according to the invention in that the insulating layer above a mastic asphalt layer and this is arranged above a layer of bituminous sealing sheets.
Da sich bei dem erfindungsgemäßen Abdichtungsaufbau somit die ein Durchdringen von Wasser verhindernde Trennschicht unterhalb der Dämmschicht befindet, ist eine wirksame Abdichtung der Rohbetondecke und somit ein Schutz der darunter befindlichen Räumlichkeiten gegen eindringende Feuchtigkeit bereits zu einem sehr frühen Stadium bei der Herstellung des Abdichtungsaufbaus zu erreichen. Da die eigentlichen Dichtungsschichten aus einer Schicht aus bituminösen Dichtungsbahnen und einer darüber angeordneten Gußasphaltschicht bestehen, sind diese nach Aushärtung der Gußasphaltschicht auch mit Fahrzeugen befahrbar. Aufgrund der vergleichsweise großen Dicke, Härte und Abriebfestigkeit der Gußasphaltschicht ist die Gefahr, daß Undichtigkeiten durch Beschädigungen infolge der Befahrung oder von anderen Arbeitsabläufen, die ausgehend von der Gußasphaltschicht durchgeführt werden, sehr gering. Die Gußasphaltschicht stellt vielmehr eine äußerst robuste Oberfläche dar, die vom Baustellenverkehr unmittelbar nach der Aushärtung nutzbar ist, so daß Nachfolgegewerke begonnen werden können, ohne daß der erfindungsgemäße Abdichtungsaufbau vollständig fertiggestellt sein muß. Nach Aufbringen der Gußasphaltschicht kann auch mit dem Ausbau der unterhalb der Rohbetondecke befindlichen Räumlichkeiten, beispielsweise Putzarbeiten o.ä., begonnen werden, da ein Eindringen von Feuchtigkeit durch die Rohbetondecke nicht mehr zu befürchten ist. Since there is therefore a penetration of the sealing structure according to the invention Water-preventing separation layer located below the insulation layer is an effective one Sealing the raw concrete ceiling and thus protecting the rooms underneath against ingress of moisture at a very early stage in the manufacture to achieve the sealing structure. Since the actual sealing layers consist of one Layer of bituminous geomembranes and a poured asphalt layer exist, these can also be driven on by vehicles after the mastic asphalt layer has hardened. Due to the comparatively large thickness, hardness and abrasion resistance of the mastic asphalt layer is the danger that leaks due to damage due to traffic or from other work processes that are carried out from the mastic asphalt layer, very low. The mastic asphalt layer rather represents an extremely robust surface can be used by construction site traffic immediately after curing, so that subsequent works can be started without the sealing structure according to the invention completely must be completed. After applying the mastic asphalt layer can also with the expansion the premises below the raw concrete ceiling, for example plastering work or the like, as moisture penetration through the raw concrete ceiling does not there is more to fear.
Vorteilhafterweise ist die Gefahr von Undichtigkeiten bei Gußasphaltschichten geringer als bei einer Abdichtung allein durch bituminöse Dichtungsbahnen. Außerdem weist die Oberfläche der Gußasphaltschicht eine vergleichsweise große Glattheit auf, insbesondere, wenn die zuvor thermoplastisch miteinander verschweißten Arbeitsnähte maschinell überschliffen werden. Aufgrund der nicht vorhandenen Überlappungsnähte, wie diese bei bituminösen Dichtungsbahnen bestehen, kommt es bei einem korrekt verlegten Gefälle zu keinerlei Stauungen von Niederschlagswasser auf der Gußasphaltschicht.The risk of leaks in poured asphalt layers is advantageously less than in the case of sealing alone with bituminous sealing membranes. The surface also shows the mastic asphalt layer has a comparatively great smoothness, especially if the machine seams previously welded to each other in a thermoplastic process. Due to the lack of overlap seams, such as those found in bituminous waterproofing membranes exist, there is no congestion on a correctly laid slope of rainwater on the mastic asphalt layer.
Gemäß einer Ausgestaltung des erfindungsgemäßen Abdichtungsaufbaus ist zwischen der Fahr- und Verschleißschicht und der Dämmschicht eine Trenn- und Gleitschicht vorhanden, die vorzugsweise aus einem diffusionsoffenen, UV-beständigen und verrottungsbeständigen Kunststoffaservlies besteht. Hierauf können beispielsweise Ortbetonplatten oder auf einer Splittschicht verlegte Bundpflastersteine oder Betonfertigteilplatten auf Stehlagern aufgebracht werden.According to one embodiment of the sealing structure according to the invention, between the Driving and wear layer and the insulation layer a separation and sliding layer available, preferably made of a diffusion-open, UV-resistant and rot-resistant Plastic fiber fleece exists. This can, for example, in-situ concrete slabs or on a Split layer laid paving stones or precast concrete slabs applied to pillow block bearings become.
Gemäß einer Weiterbildung der Erfindung ist vorgesehen, daß der Rohbeton mit einer Grundierschicht versehen ist, auf der eine Schicht aus bituminösen Dichtungsbahnen angeordnet ist, auf die wiederum die Gußasphaltschicht aufgebracht ist. Auf diese Weise wird ein inniger Verbund zwischen dem Rohbeton und den folgenden Schichten erzielt, der sich durch eine besondere Robustheit auszeichnet. Vorzugsweise besteht die Grundierschicht aus einem hitzebeständigen, lösemittelfreien, niedrigviskosen und ungefüllten Epoxidharz.According to a development of the invention it is provided that the raw concrete with a primer layer is provided, on which a layer of bituminous sealing membranes is arranged on which the mastic asphalt layer is in turn applied. In this way one becomes more intimate Bond between the raw concrete and the subsequent layers, which is characterized by a is particularly robust. The primer layer preferably consists of a heat-resistant, solvent-free, low-viscosity and unfilled epoxy resin.
Die Erfindung weiter ausgestaltend ist vorgesehen, daß die Dichtungsbahnen aus kunststoffvergütetem Bitumen hergestellt, eine Vlieseinlage aufweisen und eine APP-vergütete Oberfläche besitzen.The invention in a further embodiment provides that the sealing sheets are made of plastic-coated Bitumen produced, have a fleece insert and an APP-coated surface have.
Eine besonders vorteilhafte Ausgestaltung besteht darin, daß die Dämmschicht aus einlagig verlegten, extrudierten Polystyrol-Hartschaumplatten besteht.A particularly advantageous embodiment is that the insulation layer made of one layer installed, extruded polystyrene rigid foam panels.
Schließlich wird noch vorgeschlagen, daß durch die Oberflächenneigung der Gußasphaltschicht relativ zu der bedarfsweise geneigten Oberfläche der Rohbetondecke ein Ablauf des Wassers zu den Entwässerungsstellen bewirkt wird.Finally, it is proposed that the surface slope of the mastic asphalt layer a drain of the Water to the drainage points is effected.
Der erfindungsgemäße Abdichtungsaufbau und seine Herstellung wird nachfolgend anhand eines Ausführungsbeispiels, das in der Zeichnungsfigur dargestellt ist, näher erläutert: The sealing structure according to the invention and its manufacture is described below of an embodiment, which is shown in the drawing figure, explained in more detail:
Der erfindungsgemäße Abdichtungsaufbau besteht aus einer Rohbetondecke 1, einer Grundierschicht
2, einer Schicht aus bituminösen Dichtungsbahnen 3, einer Gußasphaltschicht 4,
einer Dämmschicht 5, einer Trenn- und Gleitschicht 6 sowie einer Fahr- und Verschleißschicht
7, wobei die vorgenannten Schichten in dieser Reihenfolge von unten nach oben übereinander
angeordnet sind.The sealing structure according to the invention consists of a raw concrete ceiling 1, a
Die Oberfläche der Rohbetondecke 1 wird durch Kugelstrahlen von Zementschlämmen sowie
sonstigen Verunreinigungen befreit. Die gereinigte Oberfläche wird mit hitzebeständigem,
lösungsmittelfreiem, niedrigviskosem und ungefülltem Epoxidharz bestrichen, wodurch die
Grundierschicht 2 erhalten wird, deren Oberfläche gleich nach dem Aufbringen mit feuergetrocknetem
Quarzsand abgestreut wird.The surface of the raw concrete ceiling 1 is shot peened by cement slurry as well
other impurities. The cleaned surface is covered with heat-resistant,
coated with solvent-free, low-viscosity and unfilled epoxy
In einem nächsten Schritt wird eine Schicht aus APP-vergüteten Dichtungsbahnen 3 aus
kunststoffmodifiziertem Bitumen mit einer Polyestervlieseinlage verlegt. Die Dicke dieser
Schicht beträgt ca. 5 mm und das Gewicht der Polyestervlieseinlage vorzugsweise mehr als
170 g pro Quadratmeter. Diese Schicht bildet die erste Abdichtungslage und besitzt eine Systemprüfung
entsprechend der Vorschrift ZTV-BEL-B1/87 für die nachfolgende Gußasphaltschicht
4. Die Dichtungsbahnen 3 werden mit Hilfe eines Mehrstrahlbrenners, einschließlich
der erforderlichen Überdeckungen an den Nähten und Stößen, vollflächig aufgeschweißt und
mit einem Drückholz lückenlos angedrückt.In a next step, a layer of APP-coated
Die zweite Abdichtungslage wird von der Gußasphaltschicht 4 gebildet, deren Dicke - abgesehen
von Bereichen, in denen Gefällekeile angelegt werden müssen - zwischen 30 und 40
mm beträgt. Es handelt sich um Gußasphalt 0/5 mm bis 0/16 mm, der splittfrei ist und aus
Bitumen B45 - B80 oder gleichwertig hergestellt ist. Die Arbeitsnähte des Gußasphalts werden
thermoplastisch miteinander verschweißt und maschinell überschliffen. Anschließend
wird die Oberfläche des Gußasphalts mit Quarzsand abgerieben.The second sealing layer is formed by the
Nach Auskühlung der Gußasphaltschicht 4 ist der bisher erstellte Teil des Abdichtungsaufbaus
problemlos mit Fahrzeugen wie Gabelstaplern oder Arbeitsbühnen befahrbar, ohne daß
die Gefahr einer Beschädigung der Abdichtung besteht. Auch kann der Innenausbau der Unterhalb
der Rohbetondecke befindlichen Räumlichkeiten unmittelbar nach Aufbringung der
Gußasphaltschicht begonnen werden. Mit der nachfolgend beschriebenen, endgültigen Fertigstellung
des erfindungsgemäßen Abdichtungsaufbaus kann - falls erwünscht - solange gewartet
werden, bis zwischenzeitlich zu erledigende Nachfolgegewerke abgeschlossen sind. After cooling the
Auf die Oberfläche der Gußasphaltschicht 4 wird eine Dämmschicht 5 aus extrudierten Polystyrol-Hartschaumplatten
mit bauaufsichtlicher Zulassung für befahrbare Flächen verwendet.
Die Dicke der Dämmschicht 5 bestimmt sich nach den Vorschriften der Wärmeschutzverordnung.
Da sich die erfindungsgemäße Dämmung oberhalb und nicht wie im Stand der Technik
unterhalb der eigentlichen Abdichtung befindet, sind die Anforderungen, wie sie bei einer
sogenannten "Umkehrdämmung" bestehen, zu erfüllen. Diese betreffen beispielsweise die
Ebenheit des Untergrundes sowie den Ausschluß eines Hohlliegens der Hartschaumplatten.
Diese Forderungen werden durch die Gußasphaltschicht 4 ohne weiteres erfüllt. Außerdem
darf die Verlegung der Polystyrol-Hartschaumplatten nur einlagig mit versetzten Stößen erfolgen.On the surface of the
Auf die Dämmschicht 5 wird eine Trennlage 6 in Form eines diffusionsoffenen, UV-beständigen
und verrottungsfesten Kunststoffaservlieses aufgebracht. Hierauf wird eine Fahrund
Verschleißschicht 7 aufgebracht, die aus einer Ortbetonplatte mit abriebfester Oberfläche
und erhöhtem Schleifverschleißwiderstand besteht. Der Beton ist widerstandsfähig gegen
Frost und Tausalze; seine Dicke bestimmt sich nach den statischen Erfordernissen.A separating layer 6 in the form of a diffusion-open, UV-resistant is placed on the
Alternativ hierzu ist im Bereich der Stellplätze auch die Verwendung von Verbundsteinpflaster
mit einer Dicke von mehr als 8 cm möglich. Die Bettungsschicht sollte aus Splitt der
Körnung 2/5 mm bestehen und eine Dicke von mehr als 5 cm aufweisen. Ferner ist als Alternative
zu der letztgenannten Variante auch die Verlegung von Betonfertigteileplatten auf geeigneten
Stehlagern möglich.Alternatively, the use of composite stone paving in the area of the parking spaces
possible with a thickness of more than 8 cm. The bedding layer should be made of
Außerdem eignet sich der erfindungsgemäße Abdichtungsaufbau auch als Untergrund für intensive Begrünungen, wie beispielsweise bei Parkanlagen, Dachgärten etc., da die Wurzelfestigkeit sichergestellt ist.In addition, the sealing structure according to the invention is also suitable as a base for intensive greening, such as in parks, roof gardens, etc., because the roots are firm is ensured.
