- the binder used here is latex, which is applied, for example, diluted onto the polymer particles. In this way, a kind of composite body or molded body is formed in the receiving space of the structure to be insulated, since the individual polymer particles are connected to each other after the curing of the latex binder.
- a method and an apparatus for producing an insulating layer in a brick has become known.
- a Dämm forung polymer particles is introduced into at least one receiving space of the brick and solidified therein.
- the particles are expandable thermoplastic polymer particles such as polystyrene beads, which are end-expanded by means of water vapor in the receiving space and thereby completely bond together.

- the invention thus provides for the first time to carry out an expansion step of the polymer particles on site at the structure to be insulated within the hollow or receiving space given there. It has surprisingly been found that such expandable polymer particles are solidifiable in the course of such end expansion under the prevailing conditions on construction sites and in conventional constructions, taking into account in particular the economic conditions, so that trickling is effectively suppressed.
- the solidification is based on such a change in the surface condition of the polymer particles that it comes to a kind of welding between adjacent polymer particles. This is also supported by the limited space available in the receiving space of the structure to be insulated, etc., since the expanding during the expansion step polymer particles each other take away the space and press each other.
- Another advantage of the invention lies in the fact that the action on the granules is limited to the relevant points in the Dämm.ung, while this is wetted in the prior art full volume with binder. This makes it possible according to the invention to keep the processing effort very low.
- the procedure of the invention has the advantage that no additional fire load is introduced by a binder, etc. in the product. Since, according to the invention, no binder is used, there are no additional concerns with regard to ecological or health-endangering aspects of the ingredients of such an insulation.
- polystyrene particles or the like it is generally known to subject polystyrene particles or the like to a double expansion.
- polymer particles are prepared by a Vorexpandier Kunststoff means of steam and then used as a raw material for the production of insulation boards.
- these pre-expanded polymer particles are introduced into a suitable mold and foamed there by means of steam and thus end-expanded, resulting in insulating blocks.
- These are then cut to standard commercial and standard insulation boards or already have the desired final dimensions, so that no reworking is required. This process takes place at the factory, since here the expansion can be reliably and accurately controlled and, in particular, there is no negative interaction of the water vapor with neighboring components.
- the polymer particles can be expanded by means of steam, which has the significant advantage that a medium is used which does not introduce any fire load into the insulation and also contains no active ingredients that would be of concern for health or environmental reasons.

- the water vapor may e.g. be introduced via existing leaks on the building in the receiving space for the granules;
- the polymer particles are first introduced pre-expanded polystyrene beads, since herewith a material with particularly good thermal insulation properties with low weight and good flow behavior is used.
- EPS insulation materials instead of the pre-expanded polystyrene beads and a Regenerat of polymer particles, which as a residue in the factory production of rigid foam insulation, or from the decay of cavity fillings or as a secondary material from the material Rececyling and preparation of foam boards, in particular of EPS insulation materials , and may have properties, in particular an expandability comparable to the polymer beads, in any mixing ratio up to the complete substitution can be used.
- the granules further milled material, which from the factory mechanical machining of hard foam Based on EPS, XPS or PUR-based, resulting in a high quality recovery of this waste.
- the proportion of milled material can preferably be less than 60 vol.% Of the granules, i. can be used to a considerable extent, without the effect of the invention would be nullified.
- the milled material is preferably used in a proportion of less than 50% by volume and in particular of less than 30% by volume of the granules, since here a greater stability of the adhesive bond can be achieved within the solidified region in the insulating filling.

- the fire retardant additive can be added in a proportion of 0.1 to 10 wt.% Based on the weight of the polymer beads.
- the intermediate material in the production of insulating panels namely pre-expanded polymer beads
- the intermediate material in the production of insulating panels can be used directly in accordance with the invention and can be used to produce a locally consolidated zone in the insulation in a building structure.
- the cavity is subsequently filled in a building with double-shell masonry by means of a Dämm thoroughlyung of polystyrene particle foam granules.
- the granules have a bead size ⁇ 6 mm in diameter and is introduced under low pressure into the receiving space within the wall.
- the polystyrene beads are distributed throughout the available space due to their good flowability. If the receiving space is e.g. However, in the joint area of two components of the outer wall does not produce a tight seal, the polystyrene beads can trickle out of the receiving space in this area.
- the respective leakage point should not be large enough to permit effective evaporation of the granules, it is also possible to provide access openings e.g. formed by a drilling process through which the water vapor can be passed.
- a window is subsequently formed in an existing double-walled masonry with a Dämm convenientlyung of expandable granules in the core. This requires a corresponding opening in the wall getting produced.
- a suitable number of access openings which are located at a predetermined distance from each other, are bored adjacent to the location of the window to be produced, through which steam is then introduced into the insulating filling. The subsequent expansion of the polystyrene beads in the insulation fillet thus solidifies the edge area around the window opening to be created, so that a separating cut can be carried out here without granules emerging from the insulation layer.
- a passage opening for the passage of a water pipe e.g. an external connection for the water extraction with Dämm forung made.
- a passage opening for the passage of a water pipe is limited locally and introduced through a single access opening water vapor in the Dämm forung. This makes it possible to achieve a solidification of the insulating fill in this area, so that subsequently the larger hole for the passage of the water pipe can be formed without this granules would escape from the core area.
- the invention can thus be carried out both with initially introduced expandable polymer beads and with 100% recycled or already incorporated regenerate, with or without an addition of milled material from expanded polymer. Furthermore, with the method according to the invention targeted local areas are solidified in a Dämm thoroughlyung.

Description
Die Erfindung betrifft ein Verfahren zur örtlichen Verfestigung einer Dämmschüttung aus Polymer-Partikelschaum-Granulat, welche zur Dämmung eines Baukörpers etc., insbesondere eines zweischaligen Mauerwerks, dient, wobei das Granulat expandierbare Polymer-Partikel aufweist.The invention relates to a method for local solidification of a Dämmschüttung of polymer particle foam granules, which for the insulation of a building, etc., in particular a clam wall masonry, is used, wherein the granules expandable polymer particles.
Es ist bekannt, Hohlräume in Außenwänden, Decken oder dergleichen von Gebäuden durch schütt- bzw. einblasbare Dämmstoffe zu dämmen. Dies ist beispielsweise bei einer so genannten Kerndämmung von zweischaligem Mauerwerk der Fall, bei der der Luftzwischenraum zwischen Innengebäudewand und äußerem Mauerwerk (Verklinkerung) mit einem granulatartigen, geschäumten Dämmstoff verfüllt wird. Hier kommen häufig zumindest vor-expandierte Polystyrol-Partikel bzw. -Perlen oder auch eine andere Art von expandierten Polymer-Partikel zum Einsatz, da diese besonders gute Wärmedämm-Eigenschaften aufweisen.It is known to insulate cavities in exterior walls, ceilings or the like of buildings by pourable or inflatable insulation materials. This is the case, for example, in a so-called core insulation of bivalve masonry, in which the air gap between interior building wall and outer masonry (Verklinkerung) is filled with a granular, foamed insulation. Here are often at least pre-expanded polystyrene particles or beads or other type of expanded polymer particles used, since they have very good thermal insulation properties.
Ein Beispiel für einen derartigen schütt- bzw. einblasbaren Dämmstoff ist in der
Allerdings hat es sich in der Praxis gezeigt, dass derartige Dämmgut-Schüttungen aufgrund ihrer sehr geringen Schüttdichte und ihrer Beweglichkeit oft nur schwer in den Hohlräumen zurückzuhalten sind. Insbesondere haben sie das Bestreben, über undichte Stellen, beispielsweise im Stoßbereich von Bauelementen, die den zu verfüllenden Hohlraum abgrenzen, oder an sonstigen Öffnungen in derartigen Wänden etc. zu entweichen.However, it has been found in practice that such Dämmgut-bedding due to their very low bulk density and their mobility are often difficult to retain in the cavities. In particular, they have the desire to leaks, for example in the joint area of components that fill the Delimiting the cavity, or escape at other openings in such walls, etc.
Um diesem Problem zu begegnen, schlagen beispielsweise die
Diese Verfahrensweise ist jedoch ebenfalls mit Nachteilen verbunden: Durch das Latex-Bindemittel wird das gute Fließverhalten beeinträchtigt, was zu einer unvollständigen Hohlraumfiillung führen kann. Weiterhin ist das Latex-Bindemittel brennbar, so dass sich die Brandlast im zu dämmenden Baukörper erhöht, was in der Regel nicht gewünscht ist. Darüber hinaus ist die Zugabe dieses Bindemittels mit einem nicht unerheblichen verfahrens- und vorrichtungstechnischen Aufwand verbunden, was die Verarbeitung verteuert. Ferner ist auch das Bindemittel selbst kein unerheblicher Kostenfaktor. Schließlich ist die Verwendung eines derartigen zusätzlichen Bindemittels und insbesondere eines Bindemittels auf Basis von Latex aus gesundheitlichen und ökologischen Gründen nicht unproblematisch.However, this procedure is also associated with disadvantages: The latex binder impairs the good flow behavior, which can lead to incomplete cavity filling. Furthermore, the latex binder is combustible, so that increases the fire load in the structure to be insulated, which is not desirable in the rule. In addition, the addition of this binder is associated with a considerable procedural and device complexity, which makes the processing more expensive. Furthermore, the binder itself is not a negligible cost factor. Finally, the use of such an additional binder and in particular a binder based on latex for health and environmental reasons is not without problems.
Darüber hinaus liegt in der Praxis häufig auch das Problem vor, dass in bestehenden Baukörpern mit vorhandenen Dämmschüttungen nachträglich Durchbrüche, Öffnungen etc. z.B. für eine Leitungsdurchführung, den nachträglichen Einbau von Fenstern oder Türen usw. geschaffen werden sollen. Wenn die Schüttung hier nicht mittels eines Bindemittels z.B. gemäß der

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren aufzuzeigen, mit welchem vor Ort mit geringem Aufwand ein Ausrieseln einer Dämmschüttung aus einem Aufnahmeraum in einem Baukörper zuverlässig unterdrückt werden kann, ohne dass nachteilbehaftete Zusatzstoffe eingesetzt werden müssen, die insbesondere einen Einfluß auf das Fließverhalten ausüben können.The invention has for its object to provide a method with which on site with little effort trickling out of a Dämmschüttung from a receiving space in a building can be reliably suppressed without disadvantageous additives must be used, which can exert an influence on the flow behavior in particular ,
Diese Aufgabe wird durch das Verfahren gemäß Anspruch 1 gelöst.This object is achieved by the method according to claim 1.
Die Erfindung sieht somit erstmals vor, vor Ort am zu dämmenden Baukörper innerhalb des dort gegebenen Hohl- bzw. Aufnahmeraums einen Expandierschritt der Polymer-Partikel auszuführen. Hierbei wurde überraschenderweise erkannt, dass derartige expandierbare Polymer-Partikel im Zuge einer solchen Endexpansion unter den auf Baustellen herrschenden Bedingungen und in üblichen Konstruktionen unter Berücksichtigung insbesondere der wirtschaftlichen Rahmenbedingungen verfestigbar sind, so dass ein Ausrieseln wirksam unterdrückt wird. Die Verfestigung basiert auf einer derartigen Änderung der Oberflächenbeschaffenheit der Polymer-Partikel, dass es zu einer Art Verschweißung zwischen benachbarten Polymer-Partikel kommt. Dies wird zudem durch den begrenzt zur Verfügung stehenden Platz im Aufnahmeraum des zu dämmenden Baukörpers etc. unterstützt, da die sich während des Expansionsschritts ausdehnenden Polymer-Partikel gegenseitig den Freiraum wegnehmen und aneinander drücken.The invention thus provides for the first time to carry out an expansion step of the polymer particles on site at the structure to be insulated within the hollow or receiving space given there. It has surprisingly been found that such expandable polymer particles are solidifiable in the course of such end expansion under the prevailing conditions on construction sites and in conventional constructions, taking into account in particular the economic conditions, so that trickling is effectively suppressed. The solidification is based on such a change in the surface condition of the polymer particles that it comes to a kind of welding between adjacent polymer particles. This is also supported by the limited space available in the receiving space of the structure to be insulated, etc., since the expanding during the expansion step polymer particles each other take away the space and press each other.
Auf diese Weise entsteht ohne jegliche Zugabe eines zusätzlichen Bindemittels de facto ein Formkörper in dem Bereich des Aufnahmeraums des zu dämmenden Baukörpers, in welchem die Expansion stattfindet. Damit kann ein Ausrieseln des Granulats an dieser Stelle zuverlässig vermieden werden. Dies ist sowohl beim erstmaligen Verfüllen des Aufnahmeraums mit dem Granulat der Fall, da sich hier erfindungsgemäß Leckagestellen schließen lassen, als auch beim nachträglichen Ausbilden von Durchbrüchen etc. im Baukörper, wo es im Zuge der Arbeiten zu Leckagestellen kommt.In this way, without any addition of an additional binder de facto a shaped body in the region of the receiving space of the structure to be insulated, in which the expansion takes place. Thus, trickling of the granules can be reliably avoided at this point. This is both at initial filling of the receiving space with the granules of the case, since here can close leakage points according to the invention, as well as the subsequent formation of breakthroughs, etc. in the building, where it comes in the course of work to leaks.
Ein weiterer Vorteil der Erfindung liegt zudem darin, dass die Einwirkung auf das Granulat auf die relevanten Stellen in der Dämmschüttung begrenzt ist, während diese im Stand der Technik vollvolumig mit Bindemittel benetzt wird. Damit lässt sich erfindungsgemäß der Bearbeitungsaufwand sehr gering halten.Another advantage of the invention lies in the fact that the action on the granules is limited to the relevant points in the Dämmschüttung, while this is wetted in the prior art full volume with binder. This makes it possible according to the invention to keep the processing effort very low.
Darüber hinaus hat die erfindungsgemäße Verfahrensweise den Vorteil, dass keine zusätzliche Brandlast durch ein Bindemittel etc. mit in das Produkt eingebracht wird. Da erfindungsgemäß kein Bindemittel eingesetzt wird, ergeben sich hieraus auch keine zusätzlichen Bedenklichkeiten im Hinblick auf ökologische oder gesundheitsgefährdende Aspekte der Inhaltsstoffe einer derartigen Dämmung.In addition, the procedure of the invention has the advantage that no additional fire load is introduced by a binder, etc. in the product. Since, according to the invention, no binder is used, there are no additional concerns with regard to ecological or health-endangering aspects of the ingredients of such an insulation.
Hierbei ist es zwar grundsätzlich bekannt, Polystyrol-Partikel oder dergleichen einer zweifachen Expansion zu unterziehen. So werden derartige Polymer-Partikel durch einen Vorexpandierschritt mittels Wasserdampf hergestellt und dann als Rohstoff zur Herstellung von Dämmstoffplatten eingesetzt. Hierzu werden diese vorexpandierten Polymer-Partikel in eine geeignete Form eingebracht und dort mittels Wasserdampf aufgeschäumt und somit end-expandiert, wodurch sich Dämmblöcke ergeben. Diese werden anschließend zu handelsüblichen und genormten Dämmplatten geschnitten oder weisen bereits die gewünschten Enddimensionen auf, so dass keine Nachbearbeitung erforderlich ist. Dieser Vorgang findet werksseitig statt, da hier die Expansion zuverlässig und exakt gesteuert werden kann und insbesondere auch keine negative Wechselwirkung des Wasserdampfes mit benachbarten Bauelementen besteht. Alternativ ist es auch bekannt, derartige vorexpandierte Polymer-Partikel zu end-expandieren und als Schüttgut einzusetzen, wie es die
Somit war es an sich zwar bereits in der Praxis bekannt, vorexpandierte und somit nochmals expandierbare Polymer-Partikel einer zweiten Expansion zu unterziehen; dieser Schritt wurde bislang jedoch ausschließlich auf Verfahrensweisen innerhalb von Herstellungsfabriken angewandt, da man offensichtlich den Eintrag von Wasserdampf in Hohlräume in zu dämmenden Baukörpern etc., wie beispielsweise den Zwischenraum in einem mehrschaligen Mauerwerk, vermeiden wollte. Ferner wurde offenbar der Prozess des Endexpandierens als zu komplex angesehen, als dass man diesen unter den Einzelfallbedingungen vor Ort an der Baustelle durchzuführen gewagt hätte. Ein Hinweis auf eine mögliche Durchführung einer Endexpansion vor Ort auf der Baustelle ist jedenfalls nicht aus dem Stand der Technik ersichtlich und ebenso wenig aus der Praxis bekannt. Eine solche Verfahrensweise wird erstmals durch die vorliegende Erfindung vorgeschlagen.Thus, it was already known in practice to subject pre-expanded and thus again expandable polymer particles to a second expansion; However, this step has hitherto been applied exclusively to procedures within manufacturing factories, since it was obviously intended to avoid the introduction of water vapor into voids in structures to be insulated, etc., such as the space in a multi-layered masonry. Furthermore, it seems that the process of end-exporting was considered too complex to be carried out under local conditions at the site. In any case, an indication of a possible implementation of an on-site final expansion at the construction site is not apparent from the prior art and is also unknown in practice. Such a procedure is first proposed by the present invention.
Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sind Gegenstand der abhängigen Ansprüche 2 bis 7.Advantageous developments of the method according to the invention are the subject of the dependent claims 2 to 7.
So können die Polymer-Partikel mittels Wasserdampf expandiert werden, was den wesentlichen Vorteil hat, dass damit ein Medium zum Einsatz kommt, welches keinerlei Brandlast in die Dämmung einbringt und das zudem auch keine Wirkstoffe enthält, die aus gesundheitlichen oder ökologischen Gründen bedenklich wären. Zudem ist die Verwendung von Wasserdampf zur Unterstützung der Expansion von Polymer-Partikel eine bekannte und bewährte Maßnahme, so dass dieser Prozess zuverlässig durchgeführt werden kann.Thus, the polymer particles can be expanded by means of steam, which has the significant advantage that a medium is used which does not introduce any fire load into the insulation and also contains no active ingredients that would be of concern for health or environmental reasons. In addition, the use of water vapor to assist in the expansion of polymer particles is a well-known and proven measure, so that this process can be carried out reliably.
Hierbei ist es von besonderem Vorteil, wenn der Wasserdampf unter Druck über einen vorbestimmten Zeitraum von weniger als 20 Sekunden in das Granulat eingebracht wird. Praktische Versuche haben gezeigt, dass ein derart kurzer Einwirkungszeitraum bereits ausreicht, um das gewünschte Expansionsergebnis zu erzielen. Zudem wird durch diese zeitlich begrenzte Zuführung des Wasserdampfes auch sichergestellt, dass nur in sehr geringem Maße Feuchtigkeit in den Baukörper eingebracht wird. Dabei hat es sich bereits als wirksam erwiesen, wenn der Wasserdampf weniger als 10 Sekunden in den Aufnahmeraum des Granulats eingebracht wird, und üblicherweise reichen bereits etwa 5 Sekunden, um die gewünschten Wirkungen zu erzielen, wobei dann besonders wenig Feuchtigkeit in den Aufnahmeraum eingebracht wird.It is particularly advantageous if the steam is introduced under pressure over a predetermined period of less than 20 seconds in the granules. Practical experiments have shown that such a short exposure period is already sufficient to achieve the desired expansion result. In addition, it is ensured by this temporary supply of water vapor that moisture is introduced into the structure only to a very limited extent. there It has already proven to be effective if the water vapor is introduced into the receiving space of the granules for less than 10 seconds, and usually already about 5 seconds are sufficient to achieve the desired effects, in which case very little moisture is introduced into the receiving space.
Dabei kann der Wasserdampf z.B. über vorhandene undichte Stellen am Baukörper in den Aufnahmeraum für das Granulat eingebracht werden; zur Verbesserung des Verfahrensablaufs wie auch zur gezielten Verfestigung im Bereich von an sich dichten Stellen des Baukörpers, beispielsweise bei der nachträglichen Ausbildung von Rohrdurchbrüchen, kann es jedoch auch vorteilhaft sein, wenn im Baukörper wenigstens eine Zugangsöffnung zur Einbringung des Wasserdampfes in den Aufnahmeraum für das Granulat ausgebildet wird. Dann lässt sich die Expansion gezielt örtlich begrenzen sowie die Feuchtigkeitszuführung in den Aufnahmeraum gering halten, wobei zugleich eine zuverlässige und hinreichende Expansion im gewünschten Bereich erzielt wird.The water vapor may e.g. be introduced via existing leaks on the building in the receiving space for the granules; However, it can also be advantageous to improve the process sequence as well as the targeted solidification in the field of intrinsically dense bodies of the structure, for example in the subsequent formation of pipe openings, if in the building at least one access opening for introducing the water vapor into the receiving space for the granules is trained. Then, the expansion can be limited locally targeted and keep the moisture supply in the receiving space low, at the same time a reliable and sufficient expansion in the desired range is achieved.
In der Praxis hat es sich als besonders vorteilhaft erwiesen, wenn die Polymer-Partikel erstmals eingebrachte vorexpandierte Polystyrol-Perlen sind, da hiermit ein Werkstoff mit besonders guten Wärmedämmeigenschaften bei geringem Gewicht und gutem Fließverhalten zum Einsatz kommt.In practice, it has proven to be particularly advantageous if the polymer particles are first introduced pre-expanded polystyrene beads, since herewith a material with particularly good thermal insulation properties with low weight and good flow behavior is used.
Alternativ kann anstelle der vorexpandierten Polystyrol-Perlen auch ein Regenerat aus Polymer-Partikeln, welches als Reststoff bei der werksmäßigen Herstellung von Hartschaumdämmstoffen, oder aus dem Rückbau von Hohlraumfüllungen oder als Sekundärmaterial aus dem stofflichen Rececyling und Aufbereitung von Hartschaumplatten, jeweils insbesondere von EPS-Dämmstoffen, anfallen kann und Eigenschaften, insbesondere eine Expandierbarkeit vergleichbar den Polymer-Perlen aufweist, in beliebigen Mischungsverhältnis bis hin zur vollständigen Substitution eingesetzt werden.Alternatively, instead of the pre-expanded polystyrene beads and a Regenerat of polymer particles, which as a residue in the factory production of rigid foam insulation, or from the decay of cavity fillings or as a secondary material from the material Rececyling and preparation of foam boards, in particular of EPS insulation materials , and may have properties, in particular an expandability comparable to the polymer beads, in any mixing ratio up to the complete substitution can be used.
In einer vorteilhaften Ausgestaltung der Erfindung weist das Granulat ferner Fräsgut auf, welches aus der werksmäßigen mechanischen Bearbeitung von Hartschaum auf EPS-, XPS- oder PUR-Basis anfällt, wodurch eine hochwertige Verwertung dieses Abfallgutes resultiert.In an advantageous embodiment of the invention, the granules further milled material, which from the factory mechanical machining of hard foam Based on EPS, XPS or PUR-based, resulting in a high quality recovery of this waste.
Dabei hat sich gezeigt, dass der Anteil an Fräsgut bevorzugt weniger als 60 Vol.% des Granulats betragen kann, d.h. in erheblichem Maße einsetzbar ist, ohne dass der erfindungsgemäße Effekt zunichte gemacht würde. Vorzugsweise wird das Fräsgut jedoch in einem Anteil von weniger als 50 Vol.% und insbesondere von weniger als 30 Vol.% des Granulats eingesetzt, da sich hier eine größere Stabilität der Haftverbindung innerhalb des verfestigten Bereiches in der Dämmschüttung erzielen lässt.It has been shown that the proportion of milled material can preferably be less than 60 vol.% Of the granules, i. can be used to a considerable extent, without the effect of the invention would be nullified. However, the milled material is preferably used in a proportion of less than 50% by volume and in particular of less than 30% by volume of the granules, since here a greater stability of the adhesive bond can be achieved within the solidified region in the insulating filling.
Die Polymer-Perlen können mit einem brandhemmenden Zusatz versehen sein. Insbesondere kann der brandhemmende Zusatz eine bromierte oder chlorierte organische Verbindung sein, welche sich in der Praxis besonders bewährt haben. Dabei kann der brandhemmende Zusatz in einem Anteil von 0,1 bis 10 Gew.% bezogen auf das Gewicht der Polymer-Perlen zugegeben werden.The polymer beads may be provided with a fire retardant additive. In particular, the flame retardant additive can be a brominated or chlorinated organic compound which has been found to be particularly useful in practice. In this case, the fire retardant additive can be added in a proportion of 0.1 to 10 wt.% Based on the weight of the polymer beads.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung wird nach Anspruch 8 eine Verwendung einer Dämmschüttung aus Polymer-Partikelschaum-Granulat mit expandierbaren Polymer-Partikeln, insbesondere vorexpandierten Polymer-Partikeln, aufgezeigt, welche zur Dämmung eines Baukörpers etc., insbesondere eines zweischaligen Mauerwerks, dient und dort in einem Aufnahmeraum angeordnet ist, wobei diese Dämmschüttung zur Herstellung einer örtlich verfestigten Dämmlage mittels einem erfindungsgemäßen Verfahren eingesetzt wird.According to a further aspect of the present invention, according to claim 8, a use of a Dämmschüttung of polymer particle foam granules with expandable polymer particles, in particular pre-expanded polymer particles, shown, which is used for the insulation of a building, etc., in particular a bivalve masonry, and is arranged there in a receiving space, said Dämmschüttung is used to produce a locally solidified insulation layer by means of a method according to the invention.
Somit lässt sich erfindungsgemäß insbesondere das Zwischengut bei der Herstellung von Dämmstoffplatten, nämlich vorexpandierte Polymer-Perlen, unmittelbar im erfindungsgemäßen Sinne einsetzen und besonders vorteilhaft zur Herstellung einer lokal verfestigten Zone in der Dämmung in einem Baukörper etc. heranziehen.Thus, according to the invention, in particular the intermediate material in the production of insulating panels, namely pre-expanded polymer beads, can be used directly in accordance with the invention and can be used to produce a locally consolidated zone in the insulation in a building structure.
Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert.The invention will be explained in more detail by means of exemplary embodiments.
In einem Ausführungsbeispiel wird in einem Gebäude mit zweischaligem Mauerwerk nachträglich der Hohlraum mittels einer Dämmschüttung aus Polystyrol-Partikelschaum-Granulat verfüllt. Das Granulat hat eine Perlgröße ≤ 6 mm Durchmesser und wird unter geringem Druck in den Aufnahmeraum innerhalb der Wandung eingebracht. Dort verteilen sich die Polystyrol-Perlen aufgrund ihrer guten Fließfähigkeit im gesamten zur Verfügung stehenden Raum. Sofern der Aufnahmeraum z.B. im Stossbereich zweier Bauelemente der Außenwand jedoch keinen dichten Abschluss herstellt, können die Polystyrol-Perlen in diesem Bereich aus dem Aufnahmeraum herausrieseln.In one embodiment, the cavity is subsequently filled in a building with double-shell masonry by means of a Dämmschüttung of polystyrene particle foam granules. The granules have a bead size ≤ 6 mm in diameter and is introduced under low pressure into the receiving space within the wall. There, the polystyrene beads are distributed throughout the available space due to their good flowability. If the receiving space is e.g. However, in the joint area of two components of the outer wall does not produce a tight seal, the polystyrene beads can trickle out of the receiving space in this area.
Um dies zu verhindern, wird erfindungsgemäß an der Leckagestelle Wasserdampf unter Druck in die Dämmschüttung eingebracht, wodurch die Polystyrol-Perlen einer Expansion unterzogen werden. Hierdurch kommt es im behandelten Bereich zu einer Art Verschweißung der einzelnen Polystyrol-Perlen miteinander, so dass sich ein fester Körper größerer Dimension ergibt. Dieser ist zu groß, um durch die Leckagestelle hindurchtreten zu können. und dichtet die Leckagestelle ab, wodurch ein Herausrieseln freier, ungebundener Polystyrol-Perlen verhindert wird.To prevent this, water vapor is introduced under pressure into the Dämmschüttung according to the invention at the leakage point, whereby the polystyrene beads are subjected to an expansion. This results in a kind of welding of the individual polystyrene beads together in the treated area, so that a solid body of larger dimensions results. This is too big to pass through the leak site. and seals the leakage site, thereby preventing trickling free, unbonded polystyrene beads.
Ergänzend kann auch z.B. eine frei vorliegende Oberseite der Dämmschüttung in der Wandung durch Einwirkung von Wasserdampf derart verfestigt werden, dass ein Herausrieseln oder Abheben von Polystyrol-Perlen hiervon beispielsweise unter Einwirkung von Windsogkräften während der Bauarbeiten verhindert werden kann.In addition, it is also possible to use e.g. a freely present top of Dämmschüttung be solidified in the wall by the action of water vapor so that trickling or lifting of polystyrene beads thereof, for example, under the influence of wind forces during construction can be prevented.
Sofern die jeweilige Leckagestelle nicht groß genug sein sollte, um eine wirksame Bedampfung des Granulats zu erlauben, ist es ferner auch möglich, Zugangsöffnungen z.B. durch einen Bohrvorgang auszubilden, durch welche hindurch der Wasserdampf geführt werden kann.Furthermore, if the respective leakage point should not be large enough to permit effective evaporation of the granules, it is also possible to provide access openings e.g. formed by a drilling process through which the water vapor can be passed.
In einem anderen Ausführungsbeispiel wird ein Fenster nachträglich in ein bestehendes doppelwandiges Mauerwerk mit einer Dämmschüttung aus expandierbarem Granulat im Kern ausgebildet. Hierzu muss eine entsprechende Öffnung in der Wand hergestellt werden. Erfindungsgemäß werden hierzu eine geeignete Anzahl von in einem vorbestimmten Abstand zueinander vorliegenden Zugangsöffnungen benachbart zum Ort des herzustellenden Fensters gebohrt, durch welche dann Wasserdampf in die Dämmschüttung eingebracht wird. Durch die anschließende Expansion der Polystyrol-Perlen in der Dämmschüttung verfestigt sich somit der Randbereich rund um die zu erstellende Fensteröffnung, so dass hier ein Trennschnitt durchgeführt werden kann, ohne dass Granulat aus der Dämmlage heraustreten würde.In another embodiment, a window is subsequently formed in an existing double-walled masonry with a Dämmschüttung of expandable granules in the core. This requires a corresponding opening in the wall getting produced. According to the invention, a suitable number of access openings, which are located at a predetermined distance from each other, are bored adjacent to the location of the window to be produced, through which steam is then introduced into the insulating filling. The subsequent expansion of the polystyrene beads in the insulation fillet thus solidifies the edge area around the window opening to be created, so that a separating cut can be carried out here without granules emerging from the insulation layer.
In einem weiteren Ausführungsbeispiel wird in analoger Weise eine Durchgangsöffnung zur Hindurchführung einer Wasserleitung z.B. eines Außenanschlusses für die Wasserentnahme mit Dämmschüttung hergestellt. Auch hier wird lokal begrenzt und durch eine einzelne Zugangsöffnung hindurch Wasserdampf in die Dämmschüttung eingebracht. Damit lässt sich eine Verfestigung der Dämmschüttung in diesem Bereich erzielen, so dass anschließend das größere Loch für die Hindurchführung der Wasserleitung ausgebildet werden kann, ohne dass hierbei Granulat aus dem Kernbereich austreten würde. Hierbei reicht beispielsweise die Ausbildung einer Zugsangsöffnung mit einem Durchmesser von 8 bis 10 mm aus, um einen Bereich mit einem Durchmesser von mehr als 100 mm zu verfestigen, wobei die Verfestigungswirkung von den Parametern der Bedampfung wie auch den Eigenschaften der Dämmschüttung abhängt und daher je nach Einsatzfall variieren kann.In a further embodiment, a passage opening for the passage of a water pipe, e.g. an external connection for the water extraction with Dämmschüttung made. Here, too, is limited locally and introduced through a single access opening water vapor in the Dämmschüttung. This makes it possible to achieve a solidification of the insulating fill in this area, so that subsequently the larger hole for the passage of the water pipe can be formed without this granules would escape from the core area. In this case, for example, the formation of a Zugsangsöffnung with a diameter of 8 to 10 mm to solidify an area with a diameter of more than 100 mm, the solidification effect of the parameters of the vapor deposition as well as the properties of Dämmschüttung depends and therefore depending on Use case may vary.
Zur Bereitstellung des Wasserdampfes kann z.B. wie in den durchgeführten praktischen Versuchen ein herkömmlicher Dampfreiniger eingesetzt werden. Ein Beispiel hierfür ist der "Kärcher Dampfreiniger 1501 VAPORAPID", der sich als geeignet für diesen Zweck erwiesen hat.To provide the water vapor, e.g. As in the practical experiments carried out a conventional steam cleaner can be used. An example of this is the "Kärcher Steam Cleaner 1501 VAPORAPID", which has proven to be suitable for this purpose.
Die Erfindung lässt sich somit sowohl mit erstmals eingebrachten expandierbaren Polymer-Perlen als auch mit 100 % wiederverwertetem oder bereits eingebautem Regenerat, mit oder ohne einen Zusatz von Fräsgut aus expandiertem Polymer, ausführen. Ferner werden mit dem erfindungsgemäßen Verfahren gezielt lokale Bereiche in einer Dämmschüttung verfestigt.The invention can thus be carried out both with initially introduced expandable polymer beads and with 100% recycled or already incorporated regenerate, with or without an addition of milled material from expanded polymer. Furthermore, with the method according to the invention targeted local areas are solidified in a Dämmschüttung.
