Description

Verfahren zum Herstellen einer Deckschicht für Betondächer Deckschicht.Process for the production of a covering layer for concrete roofs.

Die Erfindung betrifft ein Verfahren zum Herstellen einer wärmedämmenden und wasserdichten Deckschicht auf Dächern, Galerien, Balkonen und Terrassen aus Beton, mit in einer Vergussmasse eingebetteten Polystyrol-Hartschaumplatten und einer Abdeckung aus Beton-oder Steinplatten.The invention relates to a method for producing a heat-insulating and watertight cover layer on roofs, galleries, balconies and terraces made of concrete, with polystyrene rigid foam panels embedded in a casting compound and a cover made of concrete or stone panels.

Ein solches Verfahren zum Herstellen eines als "Umkehrdach" bekannten Daches, ist aus DE-A-2 736 992 bekannt. Dabei wird als Vergussmasse Heissbitumen verwendet. Insbesondere verlegt man zuerst zwei oder drei bituminös aufgebaute Dichtungsbahnen unter Verwendung von Heissbitumen als Klebemittel. Auf die oberste dieser Dichtungsbahnen wird wieder eine Schicht von Heissbitumen aufgetragen, worin die Schaumplatten gelegt werde. Wegen der nicht ausreichenden Licht- bzw. UV-Beständigkeit soll jedenfalls eine Decklage vorgesehen werden, die entweder aus Kies oder einem Anstrich bestehen kann, oder aber aus Platten oder Fliesen wodurch die Schicht begehbar wird.Such a method for producing a roof known as an "inverted roof" is known from DE-A-2 736 992. Hot bitumen is used as casting compound. In particular, you first lay two or three bituminous waterproofing membranes using hot bitumen as an adhesive. A layer of hot bitumen is again applied to the uppermost of these sealing sheets, in which the foam sheets are placed. Because of the insufficient light or UV resistance, a cover layer should be provided, which can either consist of gravel or a coat of paint, or of slabs or tiles, making the layer accessible.

Dieses bekannte Verfahren wird notwendigerweise in mehreren gesonderten Arbeitsgänge - ein Gang für jede Lage - durchgeführt, mit zwischenzeitlichen Unterbrechungen zum Aushärten bzw. Abkühlen. Ausserdem ist das Aufheizen des Bitumens notwendig. Das Verfahren ist deshalb aufwendig.This known method is necessarily carried out in several separate work steps - one step for each layer - with intermittent interruptions for hardening or cooling. It is also necessary to heat the bitumen. The process is therefore complex.

Der Erfindung liegt die Aufgabe zugrunde, eine Deckschicht für Betondächer und ein Verfahren zum Herstellen derselben zu schaffen, die in wirtschaftlicher Weise in einem einzigen Bearbeitungsgang zugleich wärmedämmend und wasserdicht ist und die sodann begehbar oder befahrbar ist.The invention has for its object to provide a covering layer for concrete roofs and a method for producing the same, which is both heat-insulating and waterproof in an economical manner in a single processing step and which can then be walked on or driven over.

Das Verfahren nach der Erfindung zeichnet sich dadurch aus, dass auf den Beton eine erste Lage von gepressten Polystyrol-Schaumplatten in Latexzementmörtel eingebettet gelegt wird, dass eine zweite Lage von Polystyrol-Schaumplatten gleichermassen auf die erste Lage gelegt wird, dass auch die senkrechten Fugen zwischen den Polystyrol-Schaumplatten mit Latexzementmoftel gefüllt werden, dass sodann die Platten oder Fliesen zur Abdeckung auf die obere Lage der Polystyrol-Schaumplatten in Latexzementmörtel eingebettet werden, und dass die Fugen zwischen den Beton-Platten oder Fliesen aus keramischem Material mit Latexzementmörtel gefüllt werden.The method according to the invention is characterized in that a first layer of pressed polystyrene foam sheets is embedded in latex cement mortar on the concrete, that a second layer of polystyrene foam sheets is placed on the first layer equally that the vertical joints between the polystyrene foam slabs are filled with latex cement mortar so that the slabs or tiles are then covered in latex cement mortar to cover the top layer of the polystyrene foam slabs, and the joints between the concrete slabs or tiles made of ceramic material are filled with latex cement mortar.

Der Grundgedanke der Erfindung besteht also darin, dass das wärmeisolierende Material in Latexzementmörtel als das die Wasserdichtigkeit gewährleistende Mittel eingebettet wird. Unter "einbetten" wird dann das volle und satte wie auch verklebte Legen der Polystyrol-Schaumplatten begriffen. Dadurch ergibt sich eine gute Belastbarkeit und Haftfestigkeit der Fliesen oder Betonplatten. Es hat sich auch herausgestellt, dass eine derartig hergestellte Deckschicht punktförmige Belastungen derart verteilt, dass die Polystyrolschaumplatten instand bleiben.The basic idea of the invention is therefore that the heat-insulating material is embedded in latex cement mortar as the agent ensuring the water resistance. Under "embed" is then understood the full and full as well as glued laying of the polystyrene foam sheets. This results in good resilience and adhesive strength of the tiles or concrete slabs. It has also been found that a cover layer produced in this way distributes point loads in such a way that the polystyrene foam sheets remain intact.

Die verwendeten Polystyrol-Schaumplatten haben vorzugsweise Abmessungen von etwa 40 x 60 cm, mehr insbesondere 41,5 x 60 cm, so dass sie einerseits ohne Gefahr des Einschliessens von Luftblasen verlegt werden können und anderseits sich leicht und verlustfrei aus handelsüblichen Formaten schneiden lassen. Eine günstige Plattendicke ist 2 cm.The polystyrene foam sheets used preferably have dimensions of about 40 x 60 cm, more particularly 41.5 x 60 cm, so that on the one hand they can be laid without the risk of air bubbles being trapped, and on the other hand they can be cut easily and without loss from commercially available formats. A favorable plate thickness is 2 cm.

Die erfindungsgemäss hergestellte Deckschicht weist ausgezeichnete Isoliereigenschaften auf und hat ausserdem ein geringes Gewicht im Vergleich zu herkömmlichen Konstruktionen. Die Wasserdichtigkeit ist optimal. Falls dennoch örtlich eine Leckage auftritt, kann diese leicht bestimmt werden und eine Reparatur ist einfach durchführbar. Zur Anpassung an die Anforderungen von Begehbarkeit für Fussgänger oder für schwerere Belastungen kann die obere Fliesenschicht eine geeignete Stärke aufweisen, wobei schwerere Fliesen auch in eine schwerere Mörtelschicht verlegt werden können. Es kann auch ein unterschiedlicher Latexzementmörtel gewählt werden.The cover layer produced according to the invention has excellent insulating properties and is also light in weight in comparison to conventional constructions. The water resistance is optimal. If a leak occurs locally, it can easily be determined and repaired easily. The upper tile layer can be of a suitable thickness to adapt to the requirements of walkability for pedestrians or for heavier loads, whereby heavier tiles can also be laid in a heavier layer of mortar. A different latex cement mortar can also be selected.

Latexzementmörtel ist ein handelsübliches Produkt, das in verschiedenen Qualitäten zur Verfügung steht. Es gibt einen Fugenmörtel, der zum Verfugen von Keramikfliesen gedacht ist, der aber vorzugsweise auch zum Kleben der Polystyrol- Schaumplatten verwendet wird. Ferner gibt es noch einen Klebemörtel zum Kleben von Keramikfliesen.Latex cement mortar is a commercially available product that is available in various qualities. There is a grout that is intended for grouting ceramic tiles, but is also preferably used to glue the polystyrene foam boards. There is also an adhesive mortar for gluing ceramic tiles.

Die Erfindung ist im folgenden anhand schematischer Zeichnungen an zwei Ausführungsbeispielen näher beschrieben, worin:-

  • Figur 1 ein Vertikalschnitt durch einen Betonfussboden mit einer Deckschicht ist, und
  • Figur 2 eine der Fig. 1 entsprechende Ansicht in der Umgebung eines Regenwasserabflusses.
The invention is described in more detail below with the aid of schematic drawings using two exemplary embodiments, in which:
  • Figure 1 is a vertical section through a concrete floor with a top layer, and
  • Figure 2 is a view corresponding to Fig. 1 in the vicinity of a rainwater drain.

Auf eine Betonunterlage 1 wird nach Befeuchtung derselben eine Schicht 2 aus Latexzementmörtel aufgebracht, der einen handelsüblichen Fugenmörtel bildet. Sodann wird eine erste Lage 3 von Polystyrolschaumplatten in dieses Mörtelbett gelegt. Die Polystyrolschaumplatten haben eine Stärke von 2 cm. Sie werden voll und satt in die Mörtelschicht gedrückt, so dass der Mörtel überall die Polystyrolschaumplatten berührt und keine Luftblasen eingeschlossen sind. Dies wird insbesondere dadurch erleichtert, dass die Platten nicht grösser als etwa 40 x 60 cm. sind. Eine bevorzugte Plattengrösse ist 41,5 x 60 cm., da sich derartige Platten leicht aus handelsüblichen Formaten ohne Verschnitt schneiden lassen.After moistening the same, a layer 2 of latex cement mortar is applied to a concrete base 1, which layer forms a commercially available grout. A first layer 3 of polystyrene foam sheets is then placed in this mortar bed. The polystyrene foam sheets are 2 cm thick. They are pressed fully into the mortar layer so that the mortar touches the polystyrene foam panels everywhere and no air bubbles are trapped. This is particularly facilitated by the fact that the panels are not larger than about 40 x 60 cm. are. A preferred plate size is 41.5 x 60 cm, since such plates can easily be cut from commercially available formats without waste.

Die Mörtelschicht 2 hat eine Stärke von etwa 2 mm. Die senkrechten Fugen 4 zwischen den einzelnen Polystyrolschaumplatten werden mit dem gleichen Mörtel aufgefüllt.The mortar layer 2 has a thickness of approximately 2 mm. The vertical joints 4 between the individual polystyrene foam panels are filled with the same mortar.

Sodann bringt man eine ganz ähnliche Mörtelschicht 5 auf die erste Lage 3 von Polystyrol- schaumplatten auf. Auf diese Mörtelschicht wird eine zweite Lage 6 von Polystyrolschaumplatten verlegt, und zwar derart, dass die senkrechten Fugen 7 versetzt gegenüber den senkrechten Fugen 4 in der ersten Lage liegen. Auch dei senkrechten Fugen 7 in der zweiten Lage werden mit Mörtel aufgefüllt.Then a very similar mortar layer 5 is applied to the first layer 3 of polystyrene foam sheets. A second layer 6 of polystyrene foam panels is laid on this mortar layer, in such a way that the vertical joints 7 are offset in relation to the vertical joints 4 in the first layer. You too vertical joints 7 in the second layer are filled with mortar.

Der isolierende und wasserdichtende Teil der Deckschicht ist hiermit fertiggestellt. Man hat nun die Wahl, diese Schichten entweder einige Tage härten zu lassen, bevor die Fliesen verlegt werden, oder aber mit dem Legen der Fliesen sofort zu beginnen.The insulating and waterproof part of the top layer is now complete. You now have the choice of either allowing these layers to harden for a few days before the tiles are laid, or to start laying the tiles immediately.

Zum Verlegen der Fliesen wird die Oberfläche der oberen Lage von Polystyrolschaumplatten mit einem Latexzementmörtel bestrichen, und zwar mit einem Klebemörtel bekannter Zusammensetzung. Danach wird eine Mörtelschicht 8 in einer solchen Stärke aufgebracht, dass die Keramikfliesen oder Betonsteine 9, nachdem sie in diese Mörtelschicht gepresst worden sind, wieder voll und satt in diese eingebettet sind. Man lässt die Fliesenschicht sodann einige Tage in Ruhe, bevor man mit dem Ausfüllen der Fugen 10 mit Fugenmörtel beginnt. Nach abermals einigen Tagen ist der Fugenmörtel ausgehärtet, und die Deckschicht kann normal benutzt werden.To lay the tiles, the surface of the top layer of polystyrene foam panels is coated with a latex cement mortar, namely with an adhesive mortar of known composition. Then a layer of mortar 8 is applied in such a thickness that the ceramic tiles or concrete blocks 9, after they have been pressed into this layer of mortar, are fully and fully embedded again. The layer of tiles is then left alone for a few days before the joints 10 are filled with grout. After a few more days, the grout has hardened and the top layer can be used normally.

Die Stärke der Mörtelschicht 8 sollte wenigstens etwa 6 mm betragen. Die Keramikfliesen oder Betonsteine 9 können beispielweise eine Stärke von 10 bis 20 mm haben.The thickness of the mortar layer 8 should be at least about 6 mm. The ceramic tiles or concrete blocks 9 can have a thickness of 10 to 20 mm, for example.

Fig. 2 zeigt die Art und Weise, in der ein Regenwasserabfluss in der Deckschicht angeordnet ist. Der Regenwasserabfluss 11 wird nach dem Aufbringen der ersten Lage 3 der Polystyrolschaumplatten gesetzt. Der freie Raum 12 zwischen dem Regenwasserabfluss und der Betonunterlage 1 sowie den Polystyrolschaumplatten in der Lage 3 wird zugleich mit dem Aufbringen der zweiten Mörtelschicht aufgefüllt.Fig. 2 shows the manner in which a rainwater drain is arranged in the cover layer. The rainwater drain 11 is set after the first layer 3 of the polystyrene foam sheets has been applied. The free space 12 between the rainwater drainage and the concrete base 1 and the polystyrene foam sheets in the layer 3 is filled at the same time with the application of the second layer of mortar.

Die verwendeten Polystyrolschaumplatten können an sich schon eine sehr grosse Belastung aufnehmen, wenn sie in der vorgeschriebenen Weise eingebettet sind. Die Belastbarkeit kann jedoch nach dadurch verbessert werden, dass man in den Fliesen senkrechte Ausnehmungen vorsieht. Diese Ausnehmungen können während des Verlegens der Fliesen dazu dienen, eingeschlossene Luft aufzunehmen. Nach dem Verlegen werden sie mit Mörtel aufgefüllt, wie in Fig. 2 an der Stelle 13 angedeutet ist. Die aufgefüllten Ausnehmungen bilden eine Art Säulen, die das Durchbiegen der Polystyrolschaumplatten verhindern.The polystyrene foam sheets used can already bear a very large load if they are embedded in the prescribed manner. The resilience can, however, be improved by providing vertical recesses in the tiles. These recesses can serve to absorb trapped air during the laying of the tiles. After laying, they are filled with mortar, as indicated at point 13 in FIG. 2. The filled-in recesses form a kind of pillars that prevent the polystyrene foam sheets from bending.

Bei der vorhergehenden Beschreibung ist vorausgesetzt, dass die Betonunterlage 1 bereits ein erforderliches Gefälle aufweist. Sollte dies nicht vorhanden sein, so ist es günstig, ein Gefälle mit Hilfe eines einfachen Zementsandmörtels herzustellen. Nach einer Aushärtungszeit von einem oder einigen Tagen wird sodann wie vorhergehend angegeben verfahren.In the preceding description, it is assumed that the concrete base 1 already has a required slope. If this is not available, it is convenient to create a slope using a simple cement sand mortar. After a curing time of one or a few days, the procedure is then as indicated above.

Die Vorteile der erfindungsgemässen Deckschicht liegen in einer ausgezeichneten Wärmeisolierung, einer optimalen Wasserdichtigkeit, einer leichten Ausbesserungsmöglichkeit bei lokalen Undichtigkeiten und einem geringen Gewicht im Vergleich zu herkömmlichen Konstruktionen. Kleine Risse in der Betonunterlage werden überdrückt, und ein waagerechter Wassertransport zwischen der Betonunterlage und den Polystyrolschaumplatten ist unmöglich, weil beide Teile festhaftend miteinander verbunden sind.The advantages of the cover layer according to the invention lie in excellent thermal insulation, optimum watertightness, easy repair with local leaks and a low weight in comparison to conventional constructions. Small cracks in the concrete base are suppressed and horizontal water transport between the concrete base and the polystyrene foam panels is impossible because the two parts are firmly bonded together.

Das Verfahren zum Herstellen derartiger Deckschichten lässt sich auch bei feuchtem Wetter (mit Ausnahme von Regen) ausführen.The process for producing such cover layers can also be carried out in damp weather (with the exception of rain).

Zum Ausfüllen der Fugen zwischen den Keramikfliesen und den aufstehenden Rändern der Betonunterlagen wird am besten nicht Mörtel, sondern ein elastischer, wasserfester Fugenkitt, etwa Silikonkitt oder ein entsprechendes Klebeband verwendet.It is best not to use mortar to fill the joints between the ceramic tiles and the upstanding edges of the concrete underlay, but rather an elastic, waterproof joint cement, such as silicone cement or a suitable adhesive tape.
