Definitions
- the invention relates to a kit for producing a thermally insulated curtain wall.
- Such curtain walls are intended in particular for existing structures, but also for new buildings. Since the rise in energy prices and the knowledge of dwindling energy sources for the generation of heating energy, they are getting more and more interested and who used in particular for the renovation of old buildings.
- Thermally insulated curtain walls are known and often consist of a layer of thermal insulation panels made of a foam plastic or the like, which are attached to the building wall, a substructure made of wooden battens or metal profiles and a facade material that is prevented from slipping at the lower end with the aid of a bracket attached to the building base .
- the dew point is shifted to the outer area of the insulation board by external insulation, so that the moisture condenses there, which in turn worsens the heat insulation effect, since damp foam plastic has no or only a small heat insulation effect.
- damp masonry lying under the thermal insulation boards cannot dry out, and the condensation of the moisture inside the thermal insulation board undesirably increases its weight.
- ventilated curtain walls in which continuous ventilation spaces are arranged between the facade material and the thermal insulation board from bottom to top in order to remove moisture from the curtain wall by the air rising therein.
- DE-A-16 83 063 describes prefabricated cladding panels for building facades made of rigid foam with such ventilation channels arranged parallel to one another.
- these have the disadvantage that in areas where the inlet or air outlet openings are closed by falling mortar, window sills or other wall projections or the like, there is an air jam but no air flow within these air channels.
- DE-A-16 83 063, Figure 4 two plates with crossed ventilation channels are placed one above the other, since in this case the air flow is a meandering way for cross ventilation should be taken, so that in this case, too, an air jam occurs in the hard foam plate when individual air outlet openings are closed. It is also uneconomical to use double the thickness of the board.
- German utility model 78 22 998 shows a thermally insulated curtain wall, which has thermal mats made of glass fibers or rock wool and adjoining spacers that support the thermal mat against the facade material. These spacers do not define any specific airways and are not distributed over the entire thermal insulation mat. Such a construction therefore results in an air build-up in areas with closed air inlet or outlet openings and insufficient rear ventilation.
- DE-A-31 18 277 describes a thermally insulated curtain wall made of thermal insulation elements and facade panels, the thermal insulation elements having molded-on spacers in the form of knobs. With this construction there is no ventilation at all, only enclosed air cushions, since the air space is interrupted at intervals from bottom to top.
- DE-A-33 29 789 shows thermally insulated curtain walls using foam plastic thermal insulation panels which have column-shaped spacers which are distributed on one side of the panel and are spaced apart from one another and are essentially of the same height and consist of one piece with the thermal insulation panel.
- these thermal insulation boards have the advantage that they form a coherent, networked system of air channels in one level, so that even when individual air inlet or outlet openings are closed, an air flow evading laterally from bottom to top is produced , which results in a much cheaper rear ventilation of the curtain wall.
- the kit according to the invention for the production of a heat-insulated curtain wall which consists of thermal insulation panels with column-shaped spacers and covering flat structures which are distributed over an entire panel side and are spaced apart from one another, essentially the same height, and consist of one piece with the thermal insulation panel, is characterized in that Spacers are arranged on the thermal insulation boards in such a way and have such distances and dimensions that there are unblocked, continuous air channels arranged diagonally between two opposite board edges and perpendicular to these two opposite board edges.
- the thermal insulation panels according to the present invention result in air suction in the diagonal and vertical directions due to the unblocked diagonal channels and vertical channels.
- the air flows through the thermal insulation board will look for the shortest and simplest, ie the vertical path from bottom to top. If, however, air inlet or outlet openings are closed, the air flows through the vertical channels, which are also unblocked, to the next possible air outlet opening. Since these diagonal channels are also unobstructed, an unimpeded air flow forms in these diagonal channels as in the vertical channels. Taken together the vertical and diagonal ventilation channels result in an optimal ventilation system that solves the task at hand.
- the vertical and diagonal ventilation channels are preferably in a common plane parallel to the surface of the thermal insulation board. If one wants to keep the vertical and diagonal ventilation channels essentially equal with regard to the ventilation effect, it is expedient to make the diagonal air channels wider than the vertical air channels. The longer path of the diagonal air ducts compared to the vertical air ducts is then compensated for by the wider, unobstructed space, so that the air flows pass through the diagonal as well as through the vertical ducts approximately equally.
- the thermal insulation panels usually consist of a foam plastic that is customary for this purpose, such as, in particular, polystyrene foam or polyurethane foam. But they can also consist of other conventional heat insulating materials with a fixed shape, such as foam concrete or the like.
- the spacers can be used in the manufacture of these panels, i.e. when foaming, are molded directly, so that no additional operation is required in the manufacture.
- the spacers can also be formed by cutting away or milling away the diagonal channels.
- the spacers can also be cylindrical or columnar with any polygonal base, the side walls not necessarily vertical; must run to the surface of the thermal insulation board. That is, the spacers can also be frustoconical or pyramid-shaped. The latter, however, is not preferred, since this makes the contact surface for the Ab deck fabric would be reduced.
- the diagonal channels have a width of about 2 to 10, preferably 3 to 5 cm and the vertical channels have a width of 0.5 to 5, preferably 1 to 2 cm.
- the spacers advantageously take up 5 to 40, preferably 10 to 30, in particular 15 to 25% of the surface of the thermal insulation boards. If they took up a smaller proportion of the surface of the thermal insulation panels, the strength of the system would be impaired, while a larger percentage would make the air ducts too small for adequate rear ventilation. It would also be difficult to get vertical channels in addition to the diagonal channels.
- the spacers are expediently located on diagonally parallel rows. Furthermore, it is expedient that the spacing of the spacers in the direction parallel to the two plate edges, between which the vertical air ducts run, is greater than the largest diameter of the spacers in the same direction.
- cover fabrics which are placed on the free ends of the spacers and thus close the open side of the air channels, can be of any nature.
- it can be lightweight panels, a further layer of foam plastic panels without spacers, facade panels themselves, or plasterable reinforcement fabrics, such as glass fiber fabrics or the like.
- cover sheets therefore do not need to be rigid plates, but can also be nonwoven fabrics, wire mesh or other flexible sheets.
- These cover sheets can be fixed on the free ends of the spacers, but it is normally preferred to simply lay them on.
- the covering sheet is not the facade material, such as a facade plate itself, the actual F assad material over the covering sheet is applied.
- This facade material can be, for example, plaster, clinker, any building material slab made of natural stone, artificial stone, concrete, plastic or metal.
- the covering surface structure can itself be the plasterable reinforcement fabric or it can be a lightweight board on which the plasterable reinforcement fabric is applied.
- a layer of soundproofing panels such as mineral fiber panels or mineral wool panels, can optionally be arranged between the building wall and the thermal insulation panel with the spacers. In addition to thermal insulation, this also gives the facade sound insulation properties, which is desirable in many cases.
- the parts of the kit according to the invention can be fastened to the wall of the building in a manner known per se, for example using plate anchors. Another possibility is to fasten them with the aid of tensioning straps which extend over the entire wall of the house and are connected at intervals through the plates to the wall of the house, for example with dowels. Such straps give the various panel elements sufficient hold on the facade to apply the desired facade materials to the outside. If a plaster facade is desired, a reinforcement mesh can be attached to the facade with the straps, which provides support for the plaster.
- the Vorhangroxima- 5 is de set in a conventional manner to a ventilation grid having air inlet openings to the air channels.
- the thermal insulation board 1 shown in Figures 1 and 2 has one piece with it, spacers 2 arranged in parallel diagonal rows, which generally have a square cross-section and only have a triangular cross-section at the edges of the board, so that when two thermal insulation boards are placed side by side, square cross-sections are in turn surrender.
- the spacers 2 on the one hand result in unobstructed diagonals le air ducts 3 and unblocked vertical air ducts 4.
- the diagonal air ducts 3 have a larger unblocked width a than the vertical air ducts 4 with their unblocked width b.
- the air rising in the curtain wall has the same tendency to flow diagonally and vertically.
- kit according to the invention is shown installed to a curtain wall.
- a thermal insulation board 1 with spacers 2 and above a lightweight panel or other facade panel 6 is fixed with the help of the plate anchor 7.
- This lightweight board can also be replaced by a reinforcing fabric to which the facade plaster can be applied.

Description
Die Erfindung betrifft einen Bausatz zur Herstellung einer wärmegedämmten Vorhangfassade. Derartige Vorhangfassaden sind insbesondere für bereits bestehende Bauwerke, aber auch für Neubauten bestimmt. Seit dem Anstieg der Energiepreise und der Erkenntnis schwindender Energiequellen für die Gewinnung von Heizenergie bekommen sie immer mehr Interesse und werden insbesondere für die Altbausanierung benutzt.The invention relates to a kit for producing a thermally insulated curtain wall. Such curtain walls are intended in particular for existing structures, but also for new buildings. Since the rise in energy prices and the knowledge of dwindling energy sources for the generation of heating energy, they are getting more and more interested and who used in particular for the renovation of old buildings.
Wärmegedämmte Vorhangfassaden sind bekannt und bestehen vielfach aus einer Lage von Wärmedämmplatten aus einem Schaumkunststoff oder dergleichen, die auf der Gebäudewand befestigt werden, einer Unterkonstruktion aus Holzlattung oder Metallprofilen und einem Fassadenmaterial, das am unteren Ende mit Hilfe einer am Gebäudesockel befestigten Halterung am Abrutschen gehindert wird.Thermally insulated curtain walls are known and often consist of a layer of thermal insulation panels made of a foam plastic or the like, which are attached to the building wall, a substructure made of wooden battens or metal profiles and a facade material that is prevented from slipping at the lower end with the aid of a bracket attached to the building base .
Bei diesen wird durch eine Außendämmung der Taupunkt in den äußeren Bereich der Dämmstoffplatte verlagert, so daß dort die Feuchtigkeit kondensiert, was seinerseits die Wärmedämmwirkung verschlechtert, da feuchter Schaumkunststoff keine oder nur geringe Wärmedämmwirkung besitzt. Außerdem kann unter den Wärmedämmplatten liegendes feuchtes Mauerwerk nicht austrocknen, und durch das Kondensieren der Feuchtigkeit innerhalb der Wärmedämmplatte wird deren Gewicht in unerwünschter Weise erhöht.In these, the dew point is shifted to the outer area of the insulation board by external insulation, so that the moisture condenses there, which in turn worsens the heat insulation effect, since damp foam plastic has no or only a small heat insulation effect. In addition, damp masonry lying under the thermal insulation boards cannot dry out, and the condensation of the moisture inside the thermal insulation board undesirably increases its weight.
Es ist auch bereits bekannt, hinterlüftete Vorhangfassaden zu konstruieren, bei denen zwischen dem Fassadenmaterial und der Wärmedämmplatte von unten nach oben durchgehende Hinterlüftungsräume angeordnet sind, um durch die darin aufsteigende Luft Feuchtigkeit aus der Vorhangfassade zu entfernen.It is also already known to construct ventilated curtain walls, in which continuous ventilation spaces are arranged between the facade material and the thermal insulation board from bottom to top in order to remove moisture from the curtain wall by the air rising therein.
Die DE-A-16 83 063 beschreibt vorgefertigte Verkleidungsplatten für Gebäudefassaden aus Hartschaumstoff mit derartigen parallel zueinander angeordneten Belüftungskanälen. Diese haben jedoch den Nachteil, daß in Bereichen, wo Infteintritts-oder Luftaustrittsöffnungen durch herabfallenden Mörtel, Fensterbänke oder andere Mauervorsprünge oder dergleichen verschlossen sind, sich innerhalb dieser Luftkanäle ein Luftstau aber keine Luftströmung befindet. Dies trifft im wesentlichen auch dann zu, wenn gemäß der DE-A-16 83 063, Figur 4, zwei Platten mit gekreuzten Belüftungskanälen übereinander gelegt werden, da in diesem Fall für eine Querdurchlüftung der Luftstrom einen mäanderartigen Weg nehmen miißte, so daß auch in diesem Fall beim Verschluß einzelner luftaustrittsöffnungen ein Luftstau in der Hartschaumplatte auftritt. Außerdem ist es unwirtschaftlich, die doppelte Plattendicke zu verwenden.DE-A-16 83 063 describes prefabricated cladding panels for building facades made of rigid foam with such ventilation channels arranged parallel to one another. However, these have the disadvantage that in areas where the inlet or air outlet openings are closed by falling mortar, window sills or other wall projections or the like, there is an air jam but no air flow within these air channels. This essentially also applies if, according to DE-A-16 83 063, Figure 4, two plates with crossed ventilation channels are placed one above the other, since in this case the air flow is a meandering way for cross ventilation should be taken, so that in this case, too, an air jam occurs in the hard foam plate when individual air outlet openings are closed. It is also uneconomical to use double the thickness of the board.
In der deutschen Gebrauchsmusterschrift 78 22 998 ist eine wärmegedämmte Vorhangfassade gezeigt, die Wärmedämmatten aus Glasfasern oder Steinwolle und daran anliegende, die Wärmedämmatte gegen das Fassadenmaterial abstützende Abstandshalter aufweist. Diese Abstandshalter definieren keine bestimmten Luftwege und sind nicht über die gesamte Wärmedämmatte verteilt. Auch eine solche Konstruktion ergibt daher in Bereichen mit verschlossenen Lufteintritts- oder Luftaustrittsöffnungen einen Luftstau und keine ausreichende Hinterlüftung.German utility model 78 22 998 shows a thermally insulated curtain wall, which has thermal mats made of glass fibers or rock wool and adjoining spacers that support the thermal mat against the facade material. These spacers do not define any specific airways and are not distributed over the entire thermal insulation mat. Such a construction therefore results in an air build-up in areas with closed air inlet or outlet openings and insufficient rear ventilation.
Weiterhin beschreibt die DE-A-31 18 277 eine wärmegedämmte Vorhangfassade aus Wärmedämmelementen und Fassadenplatten, wobei die-Wärmedämmelemente angeformte Abstandshalter in Form von Noppen haben. Bei dieser Konstruktion gibt es aber überhaupt keine Durchlüftung, sondern nur eingeschlossene Luftpolster, da in Abständen von unten nach oben der Luftraum unterbrochen ist.Furthermore, DE-A-31 18 277 describes a thermally insulated curtain wall made of thermal insulation elements and facade panels, the thermal insulation elements having molded-on spacers in the form of knobs. With this construction there is no ventilation at all, only enclosed air cushions, since the air space is interrupted at intervals from bottom to top.
Schließlich zeigt die DE-A-33 29 789 wärmegedämmte Vorhangfassaden unter Verwendung von Schaumkunststoff-Wärmedämmplatten, die auf einer Plattenseite verteilte, voneinander beabstandete, im wesentlichen gleich hohe aus einem Stück mit der Wärmedämmplatte bestehende säulenförmige Abstandshalter aufweisen. Gegenüber dem oben zunächst diskutierten Stand der Technik haben diese Wärmedämmplatten den Vorteil, daß sie in einer Ebene ein zusammenhängendes vernetztes System von Luftkanälen ergeben, so daß auch dann, wenn einzelne Lufteintritts- oder Luftaustrittsöffnungen verschlossen sind, ein von unten nach oben seitlich ausweichender Luftstrom entsteht, der eine wesentlich günstigere Hinterlüftung der Vorhangfassade ergibt.Finally, DE-A-33 29 789 shows thermally insulated curtain walls using foam plastic thermal insulation panels which have column-shaped spacers which are distributed on one side of the panel and are spaced apart from one another and are essentially of the same height and consist of one piece with the thermal insulation panel. Compared to the prior art initially discussed above, these thermal insulation boards have the advantage that they form a coherent, networked system of air channels in one level, so that even when individual air inlet or outlet openings are closed, an air flow evading laterally from bottom to top is produced , which results in a much cheaper rear ventilation of the curtain wall.
Ausgehend von der DE-A-31 29 789 bestand nun die der Erfindung zugrundeliegende Aufgabe darin; einen Bausatz zur Herstellung einer wärmegedämmten Vorhangfassade mit noch besserer Hinterlüftung zu bekommen, so daß ein Kondensieren von Feuchtigkeit in der Wärmedämmplatte praktisch völlig vermieden wird und unter der Wärmedämmplatte liegende feuchte Gebäudewände schnell und gut austrocknen können.Starting from DE-A-31 29 789, the object on which the invention is based was now; to get a kit for producing a thermally insulated curtain wall with even better ventilation, so that condensation of moisture in the thermal insulation board is practically completely avoided and damp building walls lying under the thermal insulation board can dry out quickly and well.
Der erfindungsgemäße Bausatz zur Herstellung einer.wärmegedämmten Vorhangfassade, der aus Wärmedämmplatten mit auf einer ganzen Plattenseite verteilten, von einander beabstandeten, im wesentlichen gleich hohen, aus einem Stück mit der Wärmedämmplatte bestehenden säulenförmigen Abstandshaltern und Abdeck-Flächengebilden besteht, ist dadurch gekennzeichnet, daß die Abstandshalter auf den Wärmedämmplatten derart angeordnet sind und solche Abstände und Abmessungen haben, daß zwischen ihnen sowohl diagonal zwischen zwei einander gegenüberliegenden Plattenkanten als auch senkrecht zu diesen zwei einander gegenüberliegenden Plattenkanten angeordnete unversperrte, durchgehende Luftkanäle vorliegen.The kit according to the invention for the production of a heat-insulated curtain wall, which consists of thermal insulation panels with column-shaped spacers and covering flat structures which are distributed over an entire panel side and are spaced apart from one another, essentially the same height, and consist of one piece with the thermal insulation panel, is characterized in that Spacers are arranged on the thermal insulation boards in such a way and have such distances and dimensions that there are unblocked, continuous air channels arranged diagonally between two opposite board edges and perpendicular to these two opposite board edges.
Im Gegensatz zu den Wärmedämmplatten gemäß der DE-A-33 29 789, wo sich der Luftstrom durch die Abstandshalter hindurch schlängeln muß, ergeben die Wärmedämmplatten nach der vorliegenden Erfindung infolge der unversperrten Diagonalkanäle und Vertikalkanäle einen Luftsog in diagonaler und vertikaler Richtung. Soweit die vertikalen Luftkanäle an den Eintritts- und Austrittsöffnungen unverschlossen sind, werden sich die Luftströme durch die Wärmedämmplatte hindurch den kürzesten und einfachsten, d.h. den vertikalen Weg von unten nach oben suchen. Wenn aber Lufteintritts-oder Luftaustrittsöffnungen verschlossen sind, strömt die Luft durch die ebenfalls unversperrten-durchgehenden Vertikalkanäle zu der nächstmöglichen Luftaustrittsöffnung. Da auch diese Diagonalkanäle unversperrt sind, bildet sich in diesen Diagonalkanälen eine ebenso unbehinderte Luftströmung aus wie in den Vertikalkanälen. Zusammengenommen ergeben die vertikalen und diagonalen Durchlüftungskanäle daher ein optimales Hinterlüftungssystem, das die gestellte Aufgabe löst.In contrast to the thermal insulation panels according to DE-A-33 29 789, where the air flow has to wind through the spacers, the thermal insulation panels according to the present invention result in air suction in the diagonal and vertical directions due to the unblocked diagonal channels and vertical channels. As far as the vertical air ducts at the inlet and outlet openings are not closed, the air flows through the thermal insulation board will look for the shortest and simplest, ie the vertical path from bottom to top. If, however, air inlet or outlet openings are closed, the air flows through the vertical channels, which are also unblocked, to the next possible air outlet opening. Since these diagonal channels are also unobstructed, an unimpeded air flow forms in these diagonal channels as in the vertical channels. Taken together the vertical and diagonal ventilation channels result in an optimal ventilation system that solves the task at hand.
Die vertikalen und diagonalen Durchlüftungskanäle liegen bevorzu gc in ei- ner gemeinsamen Ebene parallel zur Wärmedämmplatten-Oberfläche. Wenn mann die vertikalen und diagonalen Durchlüftungskanäle im wesentlichen gleichberechtigt hinsichtlich der Durchlüftungswirkung halten will, ist es zweckmäßig, die diagonalen Luftkanäle breiter als die vertiktalen Luftkanäle zu machen. Der längere Weg der diagonalen Luftkanäle gegenüber den vertikalen Luftkanälen wird dann durch den breiteren unversperrten Raum kompensiert, so daß die Luftströme etwa gleichermaßen durch die diagonalen wie durch die vertikalen Kanäle gehen.The vertical and diagonal ventilation channels are preferably in a common plane parallel to the surface of the thermal insulation board. If one wants to keep the vertical and diagonal ventilation channels essentially equal with regard to the ventilation effect, it is expedient to make the diagonal air channels wider than the vertical air channels. The longer path of the diagonal air ducts compared to the vertical air ducts is then compensated for by the wider, unobstructed space, so that the air flows pass through the diagonal as well as through the vertical ducts approximately equally.
Die Wärmedämmplatten bestehen gewöhnlich aus einem hierfür üblichen Schaumkunststoff, wie insbesondere Polystyrolschaum oder Polyurethanschaum. Sie können aber auch aus anderen üblichen Wärmedämmaterialien mit fester Formgebung bestehen, wie aus Schaumbeton oder dergleichen. Die Abstandshalter können bei der Herstellung dieser Platten, d.h. beim Ausschäumen, direkt angeformt werden, so daß kein zusätzlicher Arbeitsgang bei der Herstellung erforderlich ist. Die Abstandshalter können aber auch durch Wegschneiden oder Wegfräsen der Diagonalkanäle gebildet werden.The thermal insulation panels usually consist of a foam plastic that is customary for this purpose, such as, in particular, polystyrene foam or polyurethane foam. But they can also consist of other conventional heat insulating materials with a fixed shape, such as foam concrete or the like. The spacers can be used in the manufacture of these panels, i.e. when foaming, are molded directly, so that no additional operation is required in the manufacture. The spacers can also be formed by cutting away or milling away the diagonal channels.
Letztere Methode ist besonders gut anwendbar, wenn die Abstandshalter quadratischen Querschnitt besitzen, da dann nur parallel verlaufende Oberflächenkanäle mit zwei senkrecht zueinander liegenden Diagonalrichtungen ausgefräst werden müssen.The latter method can be used particularly well if the spacers have a square cross section, since then only parallel surface channels with two diagonal directions perpendicular to one another need to be milled out.
Im Prinzip können die Abstandshalter aber auch zylinderförmig oder säulenförmig mit beliebiger mehreckiger Grundfläche sein, wobei die Seitenwände nicht zwingend senkrecht ; zu der Oberfläche der Wärmedämmplatte verlaufen müssen. Das heißt,die Abstandshalter können auch kegelstumpfförmig oder pyramidenförmig ausgebildet sein. Letzteres aber ist nicht bevorzugt, da dadurch die Auflagefläche für die Abdeck-Flächengebilde verkleinert würde.In principle, the spacers can also be cylindrical or columnar with any polygonal base, the side walls not necessarily vertical; must run to the surface of the thermal insulation board. That is, the spacers can also be frustoconical or pyramid-shaped. The latter, however, is not preferred, since this makes the contact surface for the Ab deck fabric would be reduced.
Zweckmäßig ist es, daß die Diagonalkanäle eine Breite von etwa 2 bis 10, vorzugsweise 3 bis 5 cm und die Vertikalkanäle eine Breite von 0,5 bis 5, vorzugsweise von 1 bis 2 cm besitzen.It is expedient that the diagonal channels have a width of about 2 to 10, preferably 3 to 5 cm and the vertical channels have a width of 0.5 to 5, preferably 1 to 2 cm.
Damit eine ausreichende Hinterlüftung erzielt wird, nehmen die Abstandshalter günstigerweise 5 bis 40, vorzugsweise 10 bis 30r besonders 15 bis 25% der Oberfläche der Wärmedämmplatten ein. Würden sie einen geringeren Anteil der Oberfläche der Wärmedämmplatten einnehmen, würde die Festigkeit des Systems beeinträchtigt, während bei einem größeren Prozentsatz die Luftkanäle für eine ausreichende Hinterlüftung zu klein würden. Außerdem wäre es dann auch schwierig, zusätzlich zu den Diagonalkanälen Vertikalkanäle zu bekommen.In order to achieve adequate rear ventilation, the spacers advantageously take up 5 to 40, preferably 10 to 30, in particular 15 to 25% of the surface of the thermal insulation boards. If they took up a smaller proportion of the surface of the thermal insulation panels, the strength of the system would be impaired, while a larger percentage would make the air ducts too small for adequate rear ventilation. It would also be difficult to get vertical channels in addition to the diagonal channels.
Um die Diagonal- und Vertikalkanäle zu bekommen, liegen die Abstandshalter zweckmäßig auf diagonal, parallel zueinander verlaufenden Reihen. Weiterhin ist es zweckmäßig, daß der Abstand der Abstandshalter in Richtung parallel zu den beiden Plattenkanten, zwischen denen die senkrechten Luftkanäle verlaufen, größer als der größte Durchmesser der Abstandshalter in der gleichen Richtung ist.In order to get the diagonal and vertical channels, the spacers are expediently located on diagonally parallel rows. Furthermore, it is expedient that the spacing of the spacers in the direction parallel to the two plate edges, between which the vertical air ducts run, is greater than the largest diameter of the spacers in the same direction.
Die Abdeck-Flächengebilde, die auf die freien Enden der Abstandshalter aufgelegt werden und damit die offene Seite der Luftkanäle verschließen, können beliebiger Natur sein. Beispielsweise kann es sich dabei um Leichtbauplatten, um eine weitere Lage von Schaumkunststoffplatten ohne Abstandshalter, um Fassadenplatten selbst oder um verputzbare Armierungsgewebe handeln, wie Glasfasergewebe oder dergleichen. Diese Abdeck-Flächengebilde brauchen daher keine starren Platten zu sein, sondern können auch Faservliese, Drahtgeflechte oder andere flexible Flächengebilde sein. Diese Abdeck-Flächengebilde können auf den freien Enden der Abstandshalter fixiert werden, normalerweise ist es aber bevorzugt, sie lediglich aufzulegen.The cover fabrics, which are placed on the free ends of the spacers and thus close the open side of the air channels, can be of any nature. For example, it can be lightweight panels, a further layer of foam plastic panels without spacers, facade panels themselves, or plasterable reinforcement fabrics, such as glass fiber fabrics or the like. These cover sheets therefore do not need to be rigid plates, but can also be nonwoven fabrics, wire mesh or other flexible sheets. These cover sheets can be fixed on the free ends of the spacers, but it is normally preferred to simply lay them on.
Wenn das Abdeck-Flächengebilde nicht das Fassadenmaterial, wie eine Fassadenplatte, selbst ist, wird das eigentliche Fassadenmaterial über dem Abdeck-Flächengebilde aufgebracht. Dieses Fassadenmaterial kann beispielsweise Putz, Klinker, irgendeine Baustoffplatte aus Naturstein, Kunststein, Beton, Kunststoff oder.Metall sein. Im Falle einer Putzfassade kann, wie erwähnt, das Abdeckflächengebilde das verputzbare Armierungsgewebe selbst sein oder es kann eine Leichtbauplatte sein, auf der das beputzbare Armierungsgewebe aufgebracht wird.If the covering sheet is not the facade material, such as a facade plate itself, the actual F assad material over the covering sheet is applied. This facade material can be, for example, plaster, clinker, any building material slab made of natural stone, artificial stone, concrete, plastic or metal. In the case of a plaster facade, as mentioned, the covering surface structure can itself be the plasterable reinforcement fabric or it can be a lightweight board on which the plasterable reinforcement fabric is applied.
Zwischen der Bauwerkswand und der Wärmedämmplatte mit den Abstandshaltern kann gegebenenfalls noch eine Lage von Schalldämmplatten, etwa Mineralfaserplatten oder Mineralwollplatten, angeordnet werden. Dies gibt der Fassade zusätzlich zu der Wärmedämmung auch noch Schalldämmungseigenschaften, was in vielen Fällen erwünscht ist.A layer of soundproofing panels, such as mineral fiber panels or mineral wool panels, can optionally be arranged between the building wall and the thermal insulation panel with the spacers. In addition to thermal insulation, this also gives the facade sound insulation properties, which is desirable in many cases.
Die Teile des erfindungsgemäßen Bausatzes können in an sich bekannter Weise an der Gebäudewand befestigt werden, wie beispielsweise mit Hilfe von Tellerdübeln. Eine andere Möglichkeit besteht darin, sie mit Hilfe von Spannbändern zu befestigen, die sich über die gesamte Häusewand erstrecken und in Abständen durch die Platten hindurch mit der Häuserwand verbunden sind, beispielsweise mit Dübeln. Solche Spannbänder geben den unterschiedlichen Plattenelementen ausreichenden Halt auf der Fassade, um auf ihrer Außenseite die erwünschten Fassadenmaterialien aufzubringen. Wenn eine Putzfassade erwünscht ist, kann mit den Spannbändern gleichzeitig ein Armierungsgewebe auf der Fassade befestigt werden, welches den Halt für den Putz bietet.The parts of the kit according to the invention can be fastened to the wall of the building in a manner known per se, for example using plate anchors. Another possibility is to fasten them with the aid of tensioning straps which extend over the entire wall of the house and are connected at intervals through the plates to the wall of the house, for example with dowels. Such straps give the various panel elements sufficient hold on the facade to apply the desired facade materials to the outside. If a plaster facade is desired, a reinforcement mesh can be attached to the facade with the straps, which provides support for the plaster.
Da am unteren Ende der Fassade Luft in die diagonalen und vertikalen Luftkanäle eintreten muß, wird die Vorhangfassa- 5de in üblicher Weise auf ein Belüftungsgitter gesetzt, das Lufteintrittsöffnungen zu den Luftkanälen aufweist.Since air has to enter the diagonal and vertical air channels at the lower end of the facade, the Vorhangfassa- 5 is de set in a conventional manner to a ventilation grid having air inlet openings to the air channels.
Auch am oberen Fassadenabschluß ist eine Luftaustrittsmöglichkeit in üblicher Weise vorzusehen. Wenn die oberen Mündungen der Luftkanäle gegen das Eindringen von Regenwasser .abgedeckt werden sollen, ist es zweckmäßig, hierzu ein Winkelprofil zu nehmen, an dessen Vorderseite sich wiederum ein Entlüftungsgitter befindet. Wie erwähnt, ist es bei den erfindungsgemäßen Wärmedämmplatten unerheblich, ob·alle Luftaustritte am oberen Ende der Vorhangfassade zur Atmosphäre offen sind oder ob einzelne Luftaustrittsöffnungen beispielsweise durch herabfallenden Mörtel für ganze Bereiche von Luftaustrittsöffnungen etwa durch Gebäudevorsprünge, wie Fenstersimse, Balkons und dergleichen abgedeckt sind, denn die erfindungsgemäß erzielte Diagonaldurchlüftung kompensiert im Verschluß einzelner Luftaustrittsöffnungen vollständig.There is also an air outlet at the top of the facade provide in the usual way. If the upper mouths of the air ducts are to be covered against the ingress of rainwater, it is advisable to use an angle profile for this purpose, on the front of which there is again a ventilation grille. As mentioned, it is irrelevant in the novel thermal insulation boards, whether · all air outlets at the top of the curtain wall to the atmosphere are open or whether individual air outlet openings enstersimse example, by falling mortar for all areas of air outlet openings for example by building projections, such as F, balconies and the like are covered , because the diagonal ventilation achieved according to the invention completely compensates in the closure of individual air outlet openings.
Durch die Zeichnung wird die Erfindung weiter erläutert. In dieser bedeutet
Figur 1 eine Draufsicht auf eine Wärmedämmplatte des erfindungsgemäßen Bausatzes,Figur 2 eine perspektivische Darstellung der inFigur 1 dargestellten Wärmedämmplatten, teilweise weggebrochen, undFigur 3 einen Ausschnitt aus einem Teil einer wärmegedämmten Vorhangfassade aus dem erfindungsgemäßen Bausatz, teilweise weggebrochen.
- FIG. 1 shows a plan view of a thermal insulation panel of the kit according to the invention,
- Figure 2 is a perspective view of the thermal insulation panels shown in Figure 1, partially broken away, and
- Figure 3 shows a section of part of a thermally insulated curtain wall from the kit according to the invention, partially broken away.
Die in den Figuren 1 und 2 dargestellte Wärmedämmplatte 1 besitzt aus einem Stück mit ihr bestehende, in parallelen Diagonalreihen angeordnete Abstandshalter 2, die im allgemeinen quadratischen Querschnitt besitzen und nur an den Plattenrändern dreieckigen Querschnitt haben, so daß beim Nebeneinanderlegen zweier Wärmedämmplatten sich wiederum quadratische Querschnitte ergeben.The
Wie in Figur 1 durch gepunktete Linien angedeutet ist, ergeben die Abstandshalter 2 einerseits unversperrte diagonale Luftkanäle 3 und unversperrte vertikale Luftkanäle 4. Die diagonalen Luftkanäle 3 besitzen eine größere unversperrte Breite a als die vertikalen Luftkanäle 4 mit ihrer unversperrten Breite b. Dadurch hat die in der Vorhangfassade aufsteigende Luft etwa die gleiche Tendenz diagonal und vertikal zu strömen.As indicated by dotted lines in FIG. 1, the
In Figur 3 ist der erfindungsgemäße Bausatz zu einer Vorhangfassade verbaut gezeigt. Auf dem Mauerwerk 5 ist mit Hilfe des Tellerdübels 7 zunächst eine Wärmedämmplatte 1 mit Abstandshaltern 2 und darüber als Abdeck-Flächengebilde eine Leichtbauplatte oder andere Fassadenplatte 6 befestigt. Diese Leichtbauplatte kann auch durch ein Armierungsgewebe ersetzt sein, auf das der Fassadenputz aufgebracht werden kann.In Figure 3, the kit according to the invention is shown installed to a curtain wall.
