Abstract
Description
Bekannt ist das Verarbeiten von spritzbaren Mörteln und Betonen auf Zementbasis zum Herstellen von Fertigbauteilen, zum Beschichten von fertigen Bauteilen zum Korrosionsschutz bzw. zur Sanierung schadhaft gewordener Bauteile oder Konstruktionselemente. Dabei werden die Mörtel oder Betone mittels von überwiegend handgeführten Spritzköpfen flächenhaft verarbeitet.The processing of sprayable mortars and Concrete based on the manufacture of prefabricated components, for Coating of finished components for corrosion protection or Refurbishment of defective components or construction elements. Doing the mortar or concrete using predominantly hand-held Area spray heads processed.
Bekannt ist, dass dabei entweder die vorgemischten Mörtel oder Betone zunächst trocken gefördert und erst im Spritzkopf mit Wasser versetzt werden oder dass fertige Gemische mit Druckluft durch Spritzköpfe befördert werden.It is known that either the pre-mixed mortar or concrete first conveyed dry and only be mixed with water in the spray head or that finished Mixtures with compressed air are conveyed through spray heads.
Weiter ist auch bekannt, dass spritzbare Mörtel Kunststoff modifiziert, mineralisch oder rein hydraulisch aushärtend sein können.It is also known that sprayable mortar is plastic modified, mineral or purely hydraulic curing can.
Außerdem ist bekannt, dass diese Mörtel und Betone durch Fasern armiert werden können. So hat beispielsweise faserverstärkter Mörtel gegenüber unverstärktem Mörtel mit ansonsten gleichen Eigenschaften deutlich höhere mechanische Festigkeiten. Hervorzuheben ist dabei die höhere Biegezugfestigkeit bei gleichzeitiger Gewichtsreduktion.It is also known that this Mortar and Concrete can be reinforced with fibers. For example fiber reinforced mortar compared to unreinforced mortar otherwise the same properties have significantly higher mechanical strengths. highlight is the higher one Bending tensile strength with simultaneous weight reduction.
Bekannt ist ferner, dass Fassaden an Neubauten und an Sanierungsobjekten mit spritzbaren und manuell aufzutragenden Oberputzen beschichtet werden. Diese Schlussbeschichtungssysteme sind oft nicht in ausreichendem Maße in der Lage, Risse aus dem Untergrund zu kompensieren oder äußeren mechanischen Beschädigungen zu widerstehen.It is also known that facades on new buildings and renovation objects with sprayable and manual top coats to be applied are coated. These top coating systems are often insufficiently able to crack from the Compensate underground or external mechanical damage to resist.
Risse bilden sich in Fassaden, Bauteilen oder sonstigen Konstruktionselementen durch Temperatur bedingte Spannungen infolge von Witterungseinflüssen, durch Deformationsprozesse (Kriechen, Quellen und Schwinden der Baustoffe), durch Gebäudesetzungen, mechanischen Beschädigungen u.a.Cracks form in facades, components or other structural elements due to temperature-related stresses due to weather conditions, through deformation processes (creeping, swelling and shrinking of the Building materials), by building settlements, mechanical damage et al
Bei den sgn. Wärmedämmverbundsystemen – die aus einer Wärmedämmschicht (aus Hartschaum- oder Mineralwollplatten) mit Armierungs- und zusätzlichem Oberputz bestehen – liegen die Ursachen für Rissbildungen häufig an der mangelhaft verarbeiten Wärmedämmung (z.B. unzureichende Verklebung oder Befestigung von Dämmplatten, unverschlossene oder vermörtelte Fugen zwischen Wärmedämmplatten) oder an der mangelhaft hergestellten Armierungsschicht (zu dünn, Armierung in falscher Tiefe oder falsch platziert, Fehlstellen in Armierung). Die Folge sind Rissbildungen in den beiden Putzschichten, die sich oft erst nach längerer Standzeit (»5a) einstellen.With the sgn. Composite thermal insulation systems - made of a thermal barrier coating (made of hard foam or mineral wool panels) with reinforcement and additional Finish plaster - lie the causes of Cracks frequently due to poorly processed thermal insulation (e.g. inadequate bonding or fastening of insulation boards, unlocked or mortared Joints between thermal insulation boards) or on the poorly manufactured reinforcement layer (too thin, reinforcement at the wrong depth or incorrectly placed, missing parts in the reinforcement). The result is cracks in the two layers of plaster, which are often only after a long time Tool life (»5a) to adjust.
Risse in Putzschichten können zu folgenschweren Schäden durch Feuchtigkeit (Bildung von Wärmebrücken, Putzablösungen infolge von Frost-/Tauwechsel-Reaktionen) führen und müssen saniert werden. Oft werden die Mängel erst zu spät erkannt. Aufwändige Sanierungen – teilweise mit vorherigem Abriss des geschädigten Wärmedämmverbundsystems – sind die Folge.Cracks in plaster layers can serious damage due to moisture (formation of thermal bridges, plaster detachments as a result of frost / thaw change reactions) and must be remedied. Be often the deficiencies recognized too late. elaborate Refurbishments - in part with previous demolition of the injured Thermal insulation composite system - are the Episode.
Dis Schichtenfolge bisheriger Wärmedämmverbundsysteme (WDVS) ist folgende: auf den zu dämmenden Flächen werden Dämmplatten befestigt. Diese werden dann mit einem Mörtel überzogen, in dem ein Armierungsgewebe eingebettet ist. An vorgegebenen Stellen ist dieses Gewebe doppellagig oder verstärkt einzubauen. Schließlich wird dieser Aufbau mit einem Dekorputz optisch ansehnlich gestaltet. Grob gefasst handelt es sich also um drei Arbeitsstufen (Dämmung, Armierungsmörtel, Oberputz).The layer sequence of previous thermal insulation composite systems (ETICS) is as follows: on the surfaces to be insulated there are insulation boards attached. These are then covered with a mortar, in which a reinforcing fabric is embedded. At predetermined points, this fabric is double-layered or reinforced install. Finally this structure is visually designed with a decorative plaster. Roughly speaking, there are three work stages (insulation, reinforcement mortar, finishing plaster).
Neu ist, dass die bislang klassisch hergestellte Armierungsschicht durch ein Spritzverfahren ersetzt wird. Klassisch heißt, dass bisher der Mörtel durch Handarbeit auf die Dämmung aufzuziehen war. In diese Mörtelschicht war dann das Armierungsgewebe einzudrücken und zu fixieren. Anschließend wurde das Gewebe in einem weiteren Arbeitsschritt nochmals per Hand mit Mörtel überdeckt. Mit dem neuen Spritzverfahren wird der manuelle Arbeitsaufwand wesentlich verringert, da nur noch ein Arbeitsgang zur Herstellung der Armierungsmörtelschicht erforderlich ist.What is new is that so far classic manufactured reinforcement layer replaced by a spray process becomes. Classic means that so far the mortar through Handmade on the insulation was to be raised. In this layer of mortar then the reinforcement mesh had to be pressed in and fixed. Then was the fabric in a further step by hand Mortar covered. With the new spraying process, manual labor becomes essential reduced because only one work step is required to produce the reinforcing mortar layer is.
Zur Anwendung gelangt dabei ein modifizierter und hydraulisch aushärtender Spritzmörtel, der mit flexiblen Glasfasern in sehr hoher Konzentration (über 1 % Masseanteil) angereichert ist. Die Fasern weisen Längen zwischen ca. 5 und ca. 35 mm auf und geben der gespritzten Mörtelmatrix eine für Putze bislang unübliche Biegezugfestigkeit. Durch die starke Anreicherung mit Fasern entsteht im Mörtelbett eine Wirkung, die mit dem bisherigen Armierungsgewebe vergleichbar ist. Die außerordentliche rissüberbrückende Wirkung begründet sich in den Putzkomponenten (modifiziert und hydraulisch aushärtend) in Verbindung mit einer Überlagerung der zugesetzten flexiblen Glasfasern.A modified one is used and hydraulically curing Spray mortar, with flexible glass fibers in a very high concentration (over 1% Mass fraction) is enriched. The fibers have lengths between approx. 5 and approx. 35 mm and give the sprayed mortar matrix one for Plasters so far unusual Flexural strength. Due to the strong enrichment with fibers in the mortar bed an effect comparable to the previous reinforcement fabric is. The extraordinary crack-bridging effect justified in the plaster components (modified and hydraulically curing) Link with an overlay the added flexible glass fibers.
Der wesentliche Unterschied zu manuell aufgebrachten Schlussbeschichtungen besteht darin, dass kein Verreiben mehr stattfindet, durch dass Glasfaseranteile an die Oberfläche transportiert werden und verklumpen. Durch Druckluftförderung und vorgegebene Luftverteilung beim Auftragen des Spritzmörtels bleibt die Putzschicht spannungsfrei. Der Materialeinsatz ist gering, Rückpralleffekte finden nicht statt.The main difference to manual applied top coat is that no rubbing more takes place by transporting glass fiber parts to the surface become and clump together. Through compressed air delivery and specified air distribution when applying the spray mortar the plaster layer remains tension-free. The use of materials is low, Rebound effects will not take place.
