Description
"Verfahren zur Abdichtung von Rissen in Wänden" "Process for sealing cracks in walls"
Die Erfindung betrifft ein Verfahren zum Abdichten von Rissen in Wänden aus kalk- und zementgebundenen Steinen oder Blöcken und Platten aus Beton oder Gips.The invention relates to a method for sealing cracks in walls made of lime and cement-bound stones or blocks and plates made of concrete or plaster.
Es ist ein weitverbreitetes Problem, Wandflächen aus Zement, Beton, Ziegelsteinen und sonstigem Steinmaterial zu verfestigen und die in diesen Wandflächen entstandenen Risse zu versiegeln.It is a widespread problem to consolidate wall surfaces made of cement, concrete, bricks and other stone material and to seal the cracks that have formed in these wall surfaces.
Dazu ist seit einiger Zeit ein Verfahren zum Einspritzen von Kunstharzen, insbesondere von Epoxidharzen, für die Verfestigung dieser Wandflächen bekannt. Das Einspritzverfahren sieht die Ver¬ wendung von Druckluftpumpen vor, mit denen eine Harzmasse, die in der Regel aus Epoxidharz mit dem zugehörigen Härter besteht, unter einstellbarem Druck in die Risse der zu verfestigenden Wandfläche gepreßt wird. Dabei hat sich der Einsatz von Trägerzellen mit kon¬ stantem Druck bewährt.For this purpose, a method for injecting synthetic resins, in particular epoxy resins, for the consolidation of these wall surfaces has been known for some time. The injection process envisages the use of compressed air pumps with which a resin composition, which generally consists of epoxy resin with the associated hardener, is pressed into the cracks of the wall surface to be consolidated under adjustable pressure. The use of carrier cells with constant pressure has proven itself.
Bei diesen Trägerzellen kann es sich um Spritzen, um Schläuche aus Schrumpfgummi oder um ähnliche Einspritzvorrichtungen handeln. Die Trägerzellen werden in der Regel auf einer flachen Halterung aufgeschraubt, die an der Oberfläche der zu verfestigenden Wand¬ fläche im Bereich der Risse befestigt wird.These carrier cells can be syringes, hoses made of shrink rubber or similar injection devices. The carrier cells are generally screwed onto a flat holder which is attached to the surface of the wall surface to be solidified in the area of the cracks.
Die Befestigung der Halterungen und die Abdichtung der Risse er¬ folgen im allgemeinen mit Hilfe von Zweikomponenten- Epoxidklebstoffen, schnellbindenden Polyestern, Polyurethanen sowie mit spachtelbaren Flüssigklebstoffen. Die Halterung ist erst nach der Aushärtung des Klebstoffes fest angebracht und somit bereit für die Aufnahme der Trägerzellen, wofür eine Härtezeit von einigen Stunden bis zu 24 Stunden erforderlich sein kann. Eine so lange Härtezeit für derartige Klebstoffe stellt offensichtlich ein Pro¬ blem dar.The mounting of the brackets and the sealing of the cracks are generally carried out with the aid of two-component epoxy adhesives, fast-binding polyesters, polyurethanes and with fillable liquid adhesives. The holder is only firmly attached after the adhesive has hardened and is therefore ready to receive the carrier cells, which may require a hardening time of a few hours to 24 hours. Such a long curing time for such adhesives is obviously a problem.
Die bekannten, derzeit eingesetzten Verfahren haben außerdem den Nachteil, daß die Harzbasis mit dem jeweiligen Härter oder Kataly¬ sator jeweils beim Gebrauch zu mischen ist. Das bringt einen be¬ trächtlichen Materialaufwand mit sich, da das überschüssige Mate¬ rial nicht mehr verwendbar ist. Dazu kommt ferner das Problem, daß die verfügbare Zeit für die Auftragung aufgrund der kurzen Topfzeit begrenzt ist. Sie wird noch verkürzt, wenn der Kleber möglichst schnellbindend sein soll. Um diese Nachteile zu verringern, werden jeweils nur kleine Mengen zusammengemischt. Das fürht wiederum da¬ zu, daß der Mischvorgang mehrmals zu wiederholen ist, wodurch der Zeitaufwand für die Befestigung vergrößert und die Fehlermöglich¬ keit beim Mischungsverhältnis zwischen dem Härter bzw. dem Kataly¬ sator und der Harzbasis erhöht wird.The known processes currently used also have the disadvantage that the resin base has to be mixed with the respective hardener or catalyst in each case in use. This entails a considerable outlay on materials, since the excess material can no longer be used. There is also the problem that the time available for application is limited due to the short pot life. It is shortened even more if the glue is to bind as quickly as possible. To reduce these disadvantages, only small amounts are mixed together. This in turn means that the mixing process has to be repeated several times, which increases the time required for attachment and increases the possibility of errors in the mixing ratio between the hardener or the catalyst and the resin base.
Schließlich ist es nachteilig, daß diese Klebstoffe nach dem Aus¬ härten irreversibel vernetzt sind und folglich nur noch auf mecha¬ nischem Wege entfernt werden können. Dabei kommt es zu Zerstörungen in den behandelten Bereichen. Das gleiche Problem stellt sich auch in dem Fall, in dem diese be¬ kannten Klebstoffe nur zur Abdichtung der Risse anhand von manu¬ ellen Verfahren ohne Einsatz von Trägerzellen verwendet werden.Finally, it is disadvantageous that these adhesives are irreversibly crosslinked after curing and consequently can only be removed mechanically. This leads to destruction in the treated areas. The same problem also arises in the case in which these known adhesives are used only for sealing the cracks by means of manual processes without the use of carrier cells.
Die erfindungsgemäße Aufgabe besteht daher darin, ein Verfahren zur Abdichtung von Rissen zu entwickeln, bei dem die genannten Nach¬ teile nicht auftreten. Weiterhin soll die Befestigung der Trägerzellen vereinfacht und beschleunigt werden.The object of the invention is therefore to develop a method for sealing cracks in which the disadvantages mentioned do not occur. Furthermore, the attachment of the carrier cells should be simplified and accelerated.
Diese Aufgabe wird erfindungsgemäß durch Verwendung eines Schmelz¬ klebstoffs gelöst. Er dient sowohl zur Abdichtung der Risse als auch zur abnehmbaren Befestigung einer Halterung für Trägerzellen zum Einspritzen von verfestigenden Harzverbindungen. Unter "Wänden" sind auch die Decken und Böden zu verstehen.According to the invention, this object is achieved by using a hot melt adhesive. It is used both to seal the cracks and for the removable attachment of a holder for carrier cells for injecting solidifying resin compounds. "Walls" also include the ceilings and floors.
Unter "Schmelzklebstoff" ist ein bei Raumtemperatur fester Urkleb- stoff zu verstehen, der zum Benetzen der Klebeflächen vorübergehend durch Erwärmen verflüssigt wird. Vorzugsweise werden Schmelzkleb¬ stoffe auf Basis von Polyamiden und Ethylen-Vinylacetat- Copolymerisäten eingesetzt. Der Schmelzklebstoff ist nach den Ma¬ terialien auszuwählen, aus denen Wand und Halterung bestehen.“Hot melt adhesive” is to be understood as a primary adhesive which is solid at room temperature and which is temporarily liquefied by heating to wet the adhesive surfaces. Hotmelt adhesives based on polyamides and ethylene-vinyl acetate copolymers are preferably used. The hotmelt adhesive is to be selected according to the materials from which the wall and holder are made.
Bevorzugt wird die Klebstoff-Schmelze mit speziellen Geräten auf¬ getragen, die mit Granulat, Strängen oder Blöcken beschickt werden.The adhesive melt is preferably applied using special devices which are charged with granules, strands or blocks.
Die Schmelze kann vorteilhafterweise auf die Wand, aber auch auf die zur Wand hin gerichteten Seite der Halterung aufgetragen wer¬ den. Was zu bevorzugen ist, hängt von der jeweiligen Situation ab, z.B. können die Halterungen mit dem Schmelzklebstoff vorbeschichtet werden und nach einer Zwischenlagerung kurz vor dem Befestigen durch Wärme wieder aktiviert werden. Die erfindungsgemäße Verwendung des Schmelzklebstoffs erwies sich als überaus ideal für die angestrebten Ziele, da diese Art von Klebstoff mittlere Hafteigenschaften besitzt, so daß zum einen die Halterung nach Beendigung des Einspritzvorgangs einfach von der Wand abgenommen werden kann und der Klebstoff zum anderen eine ausreichende Haftfähigkeit besitzt, um die Außenschicht der Wand aus Zementmateria1 wirksam zu verfestigen und abzudichten. Daneben weist die Erfindung noch zahlreiche weitere Vorteile auf:The melt can advantageously be applied to the wall, but also to the side of the holder facing the wall. What is preferable depends on the situation, for example the holders can be pre-coated with the hot melt adhesive and reactivated by heat shortly before being fastened after an intermediate storage. The use of the hot-melt adhesive according to the invention proved to be extremely ideal for the desired goals, since this type of adhesive has medium adhesive properties, so that on the one hand the holder can be easily removed from the wall after the injection process has ended and on the other hand the adhesive has sufficient adhesiveness to effectively consolidate and seal the outer layer of the cement material wall1. The invention also has numerous other advantages:
- leichtes und praktisches Auftragen des Klebstoffs mit Hilfe ge¬ eigneter Spritzpistolen ohne Probleme in bezug auf die Dosierung, die Mischung und die Topfzeit,easy and practical application of the adhesive with the aid of suitable spray guns without problems with regard to the dosage, the mixture and the pot life,
- schnelle Durchführung, bei der die Befestigung der Halterung und die Abdichtung der Feinrisse innerhalb von wenigen Sekunden möglich ist und das Anschrauben der Trägerzelle an der Halterung bereits nach einigen Minuten erfolgen kann,- quick implementation, in which the mounting of the holder and the sealing of the fine cracks is possible within a few seconds and the support cell can be screwed onto the mounting after only a few minutes,
- einfaches Abnehmen der Trägerzellen und problemlose Reinigung der verfestigten Wandflächen, da die Heißschmelz-Dichtmasse sehr leicht vollständig entfernt werden kann, so daß sie sich besonders für äs¬ thetisch und künstlerisch hochwertige Flächen eignet, bei denen eine Verunreinigung durch synthetische Produkte möglichst zu ver¬ meiden ist;- Easy removal of the carrier cells and problem-free cleaning of the solidified wall surfaces, since the hot melt sealing compound can be completely removed very easily, so that it is particularly suitable for aesthetically and artistically high-quality surfaces in which contamination by synthetic products is to be avoided as much as possible is to be avoided;
- Wirtschaftlichkeit des Verfahrens in bezug auf den Materialver¬ brauch und Zeiteinsparung, da die Vorbereitung der zu verfestigen¬ den Wandfläche (Abdichtung der Risse und Befestigung der Halterun¬ gen) und das Einspritzen gleichzeitig erfolgen können, so daß der Zeit- und Materialaufwand der bekannten Verfahren vermieden wird, bei denen diese Vorgänge grundsätzlich in zwei Arbeitsphasen er¬ folgen müssen.- Economics of the method in terms of material consumption and time saving, since the preparation of the wall surface to be solidified (sealing of the cracks and fastening of the holders) and the injection can take place simultaneously, so that the time and material expenditure of the known ones Processes are avoided in which these processes must basically take place in two work phases.
Zur Verdeutlichung der Merkmale und der Vorteile der vorliegenden Erfindung sollen im folgenden einige praktische Ausführungsbei- spiele beschrieben werden. Bei spielIn order to clarify the features and the advantages of the present invention, some practical exemplary embodiments will be described below. For example
Es wurden praktische Versuche an Travertin, Ziegelsteinen, Beton, Kiesmaterial und Putz unter Verwendung der folgenden Schmelzkleb¬ stoffe durchgeführt:Practical tests were carried out on travertine, bricks, concrete, gravel and plaster using the following hot melt adhesives:
Ethylen-Vinylacetat-Copolymere (EVA)Ethylene-vinyl acetate copolymers (EVA)
Erweichungspunkt: 80 - 90 °C Viskosität: etwa 10 000 cps bei 200 °CSoftening point: 80 - 90 ° C Viscosity: around 10,000 cps at 200 ° C
Polyamid-Harz auf der Basis von dinieren Säuren Erweichungspunkt: 90 - 100 °C Viskosität: etwa 2 000 cps bei 160 °CPolyamide resin based on dinic acids Softening point: 90 - 100 ° C Viscosity: about 2,000 cps at 160 ° C
Bei diesen Versuchen wurde wie folgt vorgegangen: Anhand einer Spritzpistole, die im Falle des EVA mit einem Strang und im Falle des Polyamid-Harzes mit Granulat befüllt wurde, wurde eine Schmelzklebstoff-Schicht (3 - 4 mm) auf der Oberfläche der Halterung aufgetragen, die dann sofort an der Wand in Höhe des Einspritzpunktes angedrückt und 5 - 6 Sekunden lang festgehalten wurde.These tests were carried out as follows: using a spray gun, which in the case of the EVA was filled with one strand and in the case of the polyamide resin with granules, a hot-melt adhesive layer (3-4 mm) was applied to the surface of the holder, which was then immediately pressed onto the wall at the level of the injection point and held for 5-6 seconds.
Dabei wurde der Riß abgedichtet, so daß das Harz während des Ein¬ spritzvorgangs nicht herausfließen konnte.The crack was sealed so that the resin could not flow out during the injection process.
1 - 2 Minuten nach der Befestigung der Halterung wurde die mit der Epoxidharzmasse (Harz + Härter) befüllte Trägerzelle angeschraubt und die Verfestigungsmasse langsam eingespritzt. Mit beiden Schmelzklebstoffen wurden zufriedenstellende Ergebnisse erzielt, d.h. die Risse waren so abgedichtet, daß keine Epoxidharzmasse ausfloß, und die Halterungen hielten die Träger¬ zellen. 1 - 2 minutes after the holder was attached, the carrier cell filled with the epoxy resin compound (resin + hardener) was screwed on and the hardening compound was slowly injected. Satisfactory results have been achieved with both hot melt adhesives, i.e. the cracks were sealed in such a way that no epoxy resin mass flowed out, and the holders held the carrier cells.
