Description

Die Erfindung betrifft eine Spritzvorrichtung zum Auftragen wärme- und/oder schalldämmender Stoffe oder dgl. auf Mauerwerke oder dgl., in deren Austrittsende Düsen für den körnigen Füllstoff und das flüssige Bindemittel angeordnet sind, und die über Leitungen mit Vorratsbehäl- tern für den Füllstoff und das Bindemittel verbindbar sind, wobei in den Leitungen Geräte zur Zuführung der Füllstoffe und der Bindemittel von den Vorratsbehältern zur Spritzvorrichtung angeordnet sind.The invention relates to a spraying device heat for applying and / or sound-insulating materials or the like. In masonry or the like., Are arranged in the outlet end of nozzles for the granular filler and the liquid binder, and via lines to Vorratsbehäl- t s of the filler and the binder can be connected, wherein devices for supplying the fillers and the binders from the storage containers to the spraying device are arranged in the lines.

Zum Torkretieren von Mauerwerken ist es bekannt, fertig gemischten Beton aus einem Vorratsbehälter über entsprecehnde Leitungen, im allgemeinen aus gummi-elastischem Material, in denen entsprechende Zuführgeräte, z.B. Pumpen angeordnet sind, mittels Spritzpistolen auf das Mauerwerk zu spritzen.For gate locking of masonry, it is known to mix ready-mixed concrete from a storage container via corresponding lines, generally of rubber-elastic material, in which corresponding supply devices, e.g. Pumps are arranged to spray onto the masonry using spray guns.

Zur Herstellung wärme- und/oder schalldämmender Beläge auf Mauerwerken und dgl., z.B. zur Herstellung wärmedämmender Beläge aus geschäumten Kunststoffen, wie Polystyrol, und einem Bindemittel sind diese zum Torkretieren benutzten Geräte ungeeignet, weil die Raumgewichte des Füllstoffes und des Bindemittels derart voneinander abweichen, daß während des Transportes vom Vorratsbehälter bis auf die mit dem Belag zu versehende Wand die Gefahr einer Entmischung besteht.For the production of heat and / or soundproofing coverings on masonry and the like, e.g. For the production of heat-insulating coverings made of foamed plastics, such as polystyrene, and a binder, these devices are not suitable for goal locking because the density of the filler and the binder differ from each other in such a way that during transport from the storage container to the wall to be provided with the covering There is a risk of segregation.

Bekannt sind auch sogenannte Faserspritzanlagen. Bei diesen wird über eine Düse ein Bindemittel, z.B. ungesättigtes Polyester, gespritzt und gleichzeitig in einem Schneidwerk Glasfaser gehackelt und in den Strahl aus dem Bindemittel geblasen. Solche Faserspritzanlagen werden häufig zur Herstellung von Booten, Behältern usw. aus glasfaserverstärktem Kunststoff benutzt.So-called fiber spray systems are also known. In these, a binder, e.g. unsaturated polyester, sprayed and at the same time chopped in a glass fiber cutter and blown into the jet from the binder. Such fiber spraying systems are often used to manufacture boats, containers, etc. from glass fiber reinforced plastic.

Zur Herstellung von schall- und wärmedämmenden Belägen auf Mauerwerken oder dgl., insbesondere zur Herstellung wärmedämmender Beläge aus geblähtem Kunststoff, vor allem Polystyrol, und einem Bindemittel sind auch diese Anlagen aufgrund der hohen Differenz zwischen den Raumgewichten der wärmedämmenden Füllstoffe und der Bindemittel nicht geeignet.For the production of sound and heat-insulating coverings on masonry or the like. In particular for the production of heat-insulating coverings made of expanded plastic, especially Polystyrene and a binder are also unsuitable for these systems due to the large difference between the density of the insulating fillers and the binder.

Aufgabe vorliegender Erfindung ist es, ein Gerät zu schaffen, mit welchem es möglich ist, schall- und/oder wärmedämmende Beläge aus einem wärmedämmenden Füllstoff, insbesondere geblähtem Kunststoff, vor allem Polystyrol, und einem Bindemittel auf Mauerwerke oder dgl. aufzubringen, ohne daß eine Entmischung von Füllstoff und Bindemittel bis zum Auftragen des Belages auf das Mauerwerk oder dgl. erfolgt.The object of the present invention is to provide a device with which it is possible to apply sound and / or heat-insulating coverings made of a heat-insulating filler, in particular expanded plastic, especially polystyrene, and a binder to masonry or the like, without one The filler and binder are separated until the covering is applied to the masonry or the like.

Diese Aufgabe wird insbesondere durch einespritzpistole der eingangs genannten Art gelöst, mit einer zentralen Düse für den Füllstoff und um diese angeordnete Düsen für das Bindemittel.This object is achieved in particular by a spray gun of the type mentioned at the outset, with a central nozzle for the filler and nozzles arranged around the latter for the binder.

Zweckmäßig ist es, die zentrale Düse für den Füllstoff mit einer ovalen Austrittsöffnung zu versehen, die zweckmäßig in der Mitte eine Einschnürung aufweist. Für das Bindemittel sind zweckmäßig zwei Düsen vorgesehen, die vorteilhaft gegenüberliegend angeordnet sind und am zweckmäßigsten in der Richtung der längsten Achse der Austrittsöffnung der zentralen Düse für den Füllstoff. Die Austrittsöffnung der Düsen für den Füllstoff und für das Bindemittel sollten etwa in einer Ebene in der Ausmündung der Spritzpistole liegen. Der Winkel zwischen dem aus der zentralen Düse austretenden Strahl an Füllstoff und den aus den anderen Düsen austretenden Strahlen an Bindemitteln sollte verstellbar sein, um die Spritzpistole für den jeweiligen Füllstoff und das jeweilige Bindemittel optimal zu gestalten. Dieserhalb ist es vorteilhaft, die beiden Düsen für das Bindemittel mit ihren Austrittsöffnungen in einer Ebene parallel der längsten Achse und der Austrittsrichtung der Austrittsöffnung der zentralen Düse verstellbar in der Spritzpistole anzuordnen. Aus dem gleichen Grunde kann es auch von Vorteil sein, wenn die Querschnitte der zentralen Düse für den Füllstoff und/oder die Querschnitte der Düsen für das Bindemittel verstellbar sind.It is expedient to provide the central nozzle for the filler with an oval outlet opening, which expediently has a constriction in the middle. Two nozzles are expediently provided for the binder, which are advantageously arranged opposite one another and most appropriately in the direction of the longest axis of the outlet opening of the central nozzle for the filler. The outlet opening of the nozzles for the filler and for the binder should lie approximately in one plane in the mouth of the spray gun. The angle between the jet of filler emerging from the central nozzle and the jet of binder emerging from the other nozzles should be adjustable in order to optimally design the spray gun for the respective filler and binder. For this reason, it is advantageous to adjust the two nozzles for the binder with their outlet openings in a plane parallel to the longest axis and the outlet direction of the outlet opening of the central nozzle in the spray gun. For the same reason it can also be of advantage if the cross sections of the central nozzle for the filler and / or the cross sections of the nozzles for the binder are adjustable.

Durch die Art der Gestaltung bedingt, werden die Strahlen des Bindemittels seitlich in den Strahl des Füllstoffes gesprüht, und zwar unmittelbar nach dem Austritt des Füllstoffes aus der Austrittsöffnung der zentralen Düse. Die einzelnen Füllstoffkörner kommen also sehr innig mit dem Bindemittel in Berührung und werden allseitig mit dem Bindemittel überzogen, weil der Weg von der Ausmündung der Spritzpistole bis an das mit einem Belag zu versehende Mauerwerk oder dgl. relativ kurz ist, findet eine Entmischung von Bindemittel und Füllstoff nicht statt, und zwar auch dann nicht, wenn der Füllstoff aus geblähtem, körnigem Polystyrol besteht und das Bindemittel aus einem flüssigen Kleber. Dabei ist es möglich, in der Ausmündung der Spritzpistole noch zusätzliche Düsen vorzusehen, durch die z.B. Fasermaterial in die Strahlen aus Dämmstoffen und Bindemittel gesprüht wird. Diese Düsen werden, wie die Düsen für den Füllstoff und für das Bindemittel mit dem Vorratsbehälter verbunden und mit Zuführungsgeräten versehen.Due to the type of design, the jets of the binder are sprayed laterally into the jet of the filler, immediately after the filler has emerged from the outlet opening of the central nozzle. The individual filler grains therefore come into very intimate contact with the binder and are coated with the binder on all sides, because the path from the mouth of the spray gun to the masonry to be provided with a covering or the like is relatively short Filler does not take place, even if the filler consists of expanded, granular polystyrene and the binder consists of a liquid adhesive. It is possible to provide additional nozzles in the mouth of the spray gun, through which e.g. Fiber material into which rays of insulating materials and binders are sprayed. These nozzles, like the nozzles for the filler and for the binder, are connected to the storage container and provided with supply devices.

Die Spritzvorrichtung kann weiterhin auch aus einer Breitstrahldüse für den körnigen Füllstoff und einer oder mehreren ein- oder beidseitig parallel der längsten Achse neben der Breitstrahldüse angeordneten, das flüssige Bindemittel in den Strahl des körnigen Füllstoffes spritzenden Düsen für das flüssige Bindemittel bestehen.The spraying device can also consist of a wide-jet nozzle for the granular filler and one or more nozzles arranged on one or both sides parallel to the longest axis next to the wide-jet nozzle and spraying the liquid binder into the jet of the granular filler for the liquid binder.

Dabei sind zweckmäßig auch die Düsen für das flüssige Bindemittel Vreitstrahldüsen, bei denen die längste Achse der Austrittsöffnung parallel der längsten Achse der Austrittsöffnung der Breitstrahldüse für den körnigen Füllstoff liegt.The nozzles for the liquid binder are also expedient, in which the longest axis of the outlet opening is parallel to the longest axis of the outlet opening of the wide-jet nozzle for the granular filler.

Vorzugsweise ist beidseitig der Breitstrahldüse für den körnigen Füllstoff zumindest eine Düse für das flüssige Bindemittel vorteilhaft mittig angeordnet.Preferably, at least one nozzle for the liquid binder is advantageously arranged in the center on both sides of the wide jet nozzle for the granular filler.

Durch die Gestaltung der Düse für den körnigen Füllstoff als Breitstrahldüse kann der körnige Füllstoff in raltiv große Mengen mit entsprechendem Druck auf eine relativ breite Fläche des Mauerwerkes aufgebracht werden. Die Düsen für das Bindemittel sind derart angeordnet, daß das Bindemittel gleichmäßig im ganzen Strahl aus dem körnigen Füllstoff verteilt wird. Aus diesem Grunde sollen die Düsen für das Bindemittel vorzugsweise ebenfalls Breitstrdil- düsen sein, bei denen die längste Achse der Austrittsöffnung parallel der längsten Achse der Austrittsöffnung der Breitstrahldüse für den körnigen Füllstoff liegt. Die Austrittsenden der Düsen für das flüssige Bindemittel sind derart gestaltet bzw. angeordnet, daß das Bindemittel eine möglichst gelichmäßige Verteilung im Strahl des körnigen Füllstoffes erfährt.By designing the nozzle for the granular filler as a wide jet nozzle, the granular filler can be applied in relatively large amounts with appropriate pressure to a relatively wide area of the masonry. The nozzles for the binder are arranged in such a way that the binder is distributed uniformly throughout the jet of the granular filler. For this reason, the nozzles for the binder are preferably also Breitstr d il- be nozzles where the longest axis of the outlet opening is parallel to the longest axis of the outlet opening of the wide jet nozzle for the granular filler. The outlet ends of the nozzles for the liquid binder are designed or arranged in such a way that the binder is distributed as uniformly as possible in the jet of the granular filler.

Im Mantel 12 der Spritzpistole nach den Fig. 1 bis 3 sind in der Ausmündung 5 eine zentrale Düse 1 für den Füllstoff und neben dieser gegenüberliegend 2 Düsen 2 für das Bindemittel angeordnet. Die Austrittsöffnung 3 der zentralen Düse 1 für den Füllstoff ist oval gestaltet und weist in der Mitte eine Einschnürung 4 auf, so daß sie in der Aufsicht auf die Ausmündung 5 8-förmig gestaltet ist. Durch diese Gestaltung wird erreicht, daß der Strahl aus Füll- stoff fächerförmig aus der zentralen Düse 1 austritt. Die beiden Düsen 2 für das Bindemittel sind zweckmäßig in einer Ebene parallel zur längsten Achse der Austrittsöffnung 3 und zur Austrittsrichtung des Füllstoffes angeordnet und in Richtung auf die Austirttsöffnung 3 der Düse 1 geneigt. So wird erreicht, daß die Strahlen aus Bindemittel in den Strahl aus Füllstoff gesprüht werden und sich in diesem sowie auf den einzelnen Füllstoffkörnern gleichmäßig verteilen. Als Füllstoff dient dabei zweckmäßig geblähtes, körniges Polystyrol und als Bindemittel ein solches, welches gut auf Polystyrol und Mauerwerk haftet, z.B. ein Epoxydharz. Die zentrale Düse 1 ist auf einem Zuführrohr 13 befestigt, welches durch den Mantel 12 geführt ist und am der Ausmündung 5 gegenüberliegenden Ende durch den Mantel. Hier ist das Zuführrohr 13 mit einem entsprechenden Verbindungsmittel z.B. einem Schraubgewinde versehen, auf welchem eine Schraubmuffe aufschraubbar ist, welches sich an einem Ende der Zuführung 9 für den Füllstoff befindet. Die Düsen 2 für das Bindemittel sind auf Zuführungsrohren 14 angeordnet, die durch den Mantel 12 und den Handgriff 15 zum Anschlußstück für die Zuführung 11 für das Bindemittel führen. Innerhalb des Handgriffes 15 sind die beiden Zuführungsrohre 14 miteinander verbunden. Die Verbindung zwischen den Zuführungsrohren 14 und der Zuleitung 11 kann in gleicher Weise erfolgen, wie zwischen dem Zuführungsrohr 13 für den Füllstoff und die Zuleitung 9. Die Düsen 2 sind in einer Ebene, die parallel der längsten Achse der Austrittsöffnung 3 der Düse 1 und der Austrittsrichtung des Füllstoffes liegt, gelenkig mit den Zuführungsrohren 14 verbunden, um die Austrittswinkel zwischen der Düse 1 für den Füllstoff und den Düsen 2 für das Bindemittel entsprechend dem Füllstoff und dem Bindemittel einstellen zu können. Die Gelenkstelle 16 kann in üblicher, an sich bekannter, nicht dargestellter Weise gestaltet sein. Um mit der erfindungsgemäßen Spritzpistole auch draußen und bei stärkerem Wind arbeiten zu können, ist es möglich, noch eine Schutzkappe 6 vorzusehen, die über die Ausmündung 5 der Spritzpistole schiebbar ist. Die Zuleitung zur zentralen Düse 1 kommt vom Vorratsbehälter 7 für das Bindemittel. In dieser Zuleitung 9 ist noch ein Zuführgerät 8, z.B. eine Pumpe, vorgesehen, um den FüllsiDfE aus dem Vorratsbehälter 7 mit dem nötigen Druck zur Austrittsöffnung 3 der Düse 1 zu fördern. Dabei ist es vorteilhaft, zwischen dem Vorratsbehälter 7 und dem Zuführgerät 8 in der Zuleitung noch einen Regler 10 vorzusehen. Dieser Regler 10 besteht in einfachster Ausführung aus einer auf die Zuleitung 9 gesetzten Muffe mit einer Durchbrechung in der Wandung, die mit einer Durchbrechung in der Wandung der Zuleitung 9 durch Drehung der Muffe in Deckung bringbar ist. Die Zuleitung 11 zu den Düsen 2 kommt vom Vorratsbhälter 17 für das Bindemittel. Der Vorratsbehälter 17 ist zweckmäßig ein Kombinationsgerät, welches einen Vorratsraum aufweist und eine Pumpe,mittels der das Bindemittel aus dem Vorratsraum durch die Zuleitung zu den Düsen 2 für das Bindemittel gepreßt wird. Dabei sollte vermieden werden, daß in die Zuleitung 11 Luft gerät, weil die Luft zu einem Verschäumen des Bindemittels nach dem Austritt aus den Düsen 2 führen kann und damit zu einer schlechten Haftung auf der Oberfläche der Körner des Füllstoffes.In the jacket 12 of the spray gun according to FIGS. 1 to 3, a central nozzle 1 for the filler and 2 nozzles 2 for the binder are arranged opposite it in the mouth 5. The outlet opening 3 of the central nozzle 1 for the filler is oval in shape and has a constriction 4 in the middle, so that it is 8-shaped when viewed from the mouth 5. Due to this design that the beam from F üll- material is achieved, a fan shape emerges from the central nozzle. 1 The two nozzles 2 for the binder are expediently arranged in a plane parallel to the longest axis of the outlet opening 3 and to the outlet direction of the filler and inclined in the direction of the outlet opening 3 of the nozzle 1. It is thus achieved that the jets of binder are sprayed into the jet of filler and are distributed evenly in this and on the individual filler grains. Expediently, expanded, granular polystyrene serves as the filler, and a binder which adheres well to polystyrene and masonry, for example an epoxy resin, serves as a binder. The central nozzle 1 is fastened on a feed pipe 13 which is guided through the jacket 12 and at the end opposite the mouth 5 through the jacket. Here, the feed pipe 13 is provided with a corresponding connecting means, for example a screw thread, on which a screw sleeve can be screwed, which is located at one end of the feed 9 for the filler. The nozzles 2 for the binder are arranged on feed pipes 14 which lead through the jacket 12 and the handle 15 to the connection piece for the feed 11 for the binder. The two feed pipes 14 are connected to one another within the handle 15. The connection between the feed pipes 14 and the Supply line 11 can take place in the same way as between the feed pipe 13 for the filler and the supply line 9. The nozzles 2 are articulated with the in a plane that is parallel to the longest axis of the outlet opening 3 of the nozzle 1 and the direction of exit of the filler Feed pipes 14 connected in order to be able to adjust the outlet angles between the nozzle 1 for the filler and the nozzles 2 for the binder in accordance with the filler and the binder. The articulation point 16 can be designed in a conventional manner known per se, not shown. In order to be able to work outside and in stronger wind with the spray gun according to the invention, it is also possible to provide a protective cap 6 which can be pushed over the mouth 5 of the spray gun. The feed line to the central nozzle 1 comes from the storage container 7 for the binder. A feed device 8, for example a pump, is also provided in this feed line 9 in order to convey the filling fluid from the storage container 7 with the necessary pressure to the outlet opening 3 of the nozzle 1. It is advantageous to provide a regulator 10 in the feed line between the storage container 7 and the feed device 8. The simplest version of this regulator 10 consists of a sleeve placed on the feed line 9 with an opening in the wall, which can be brought into alignment with an opening in the wall of the feed line 9 by rotating the sleeve. The feed line 11 to the nozzles 2 comes from the storage container 17 for the binder. The storage container 17 is expediently a combination device which has a storage space and a pump, by means of which the binder is pressed out of the storage space through the feed line to the nozzles 2 for the binder. It should be avoided that air gets into the supply line 11 because the air can cause the binder to foam after exiting from the nozzles 2 and thus lead to poor adhesion to the surface of the filler grains.

In einer weiteren beispielhaften Ausführungsform nach den Fig. 4 bis 6 besteht die Breitstrahldüse 101 für den körnigen Füllstoff aus der inneren Wand 105, der äußeren Wand 106 und den beiden Seitenwänden 111. Die Breite der inneren Wand 105 und der äußeren Wand 106 nimmt vom Eintrittsstutzen 112 zur Austrittsöffnung 104 stetig zu, während die Breite der beiden Seitenwände 111 über die gesamte Länge der Breitstrahldüse 101 gleich bleibt.In a further exemplary embodiment according to FIGS. 4 to 6, the wide jet nozzle 101 for the granular filler consists of the inner wall 105, the outer wall 106 and the two side walls 111. The width of the inner wall 105 and the outer wall 106 decreases from the inlet nozzle 112 to the outlet opening 104, while the width of the two side walls 111 remains the same over the entire length of the wide jet nozzle 101.

Am Ende des Eintrittsstutzens 112 ist die Breitstrahldüse 101, abgesehen von der Durchführung des Eintrittsstutzens 112, verschlossen. Vom Eintrittsstutzen 112 zur Austrittsöffnung 104 ist die Breitstrahldüse 101 bogenförmig gestaltet, wie aus den Fig. 4 und 5 ersichtlich. Diese Gestaltung hat den Vorteil, daß der Strahl des körnigen Füllstoffes auch dann über die ganze Austrittsöffnung 104 gleichmäßig verteilt austritt, wenn man die Spritzvorrichtung schräg hält. Die innere Wand 105 kann gegenüber der äußeren Wand 106 an der Austrittsöffnung 104 verkürzt sein. Am der Austrittsöffnung 104 gegenüberliegenden Ende ist die Breitstrahldüse 101 in einer Halterung 113 befestigt. An dieser Halterung 113 ist ein Handgriff 114 angeordnet. Neben der Breitstrahldüse 101,parallel der längsten Achse, sind eine oder mehrere Düsen 103 für das flüssige Bindemittel angeordnet, durch die das flüssige Bindemittel in den Strahl des körnigen Füllstoffes gespritzt wird. Vorteilhaft ist es, sowohl an der äußeren Wand 106 als auch an der inneren Wand 105, zweckmäßig mittig, je eine Düse 103 für das flüssige Bindemittel vorzusehen. Die Austrittsenden dieser Düsen 103 für das flüssige Bindemittel sind zweckmäßig ebenfalls als Breitstrahldüsen gestaltet. Die längste Achse der Austrittsöffnungen dieser Düse 103 für das flüssige Bindemittel sollen parallel der längsten Achse 102 der Austrittsöffnung 104 der Breitstrahldüse 101 für den körnigen Füllstoff liegen. Die Austrittsöffnungen der Düsen 103 liegen dabei etwa in Höhe der freien Enden der äußeren Wand 106 bzw. der inneren Wand 105. Sie sind derart gestaltet und angeordnet, daß das flüssige Bindemittel möglichst gleichmäßig im Strahl des körnigen Füll- stoffes verteilt wird. An den Eintrittsstutzen 112 der Breitstrahldüse 101 ist die Zuführung 109 für den körnigen Füllstoff angeschlossen. Dieser körnige Füllstoff befindet sich in einem Vorratsbehälter 107, der sich nach unten verjüngt, zumindest einen zur Mitte abfallenden Boden hat. Unter dem Boden des Vorratsbehälters 107 ist ein waagerechter Rohrstutzen 110 angeordnet, dessen Innenraum mit dem Innenraum des Vorratsbehälters 107 in Verbindung steht. An das eine Ende dieses Rphrstutzens 110 ist die Zuführungsleitung 109 zur Breitstrahldüse 101 angeschlossen. Am anderen Ende des Stutzens 110 befindet sich ein Gebläse 108, mit dem der körnige Füllstoff aus dem Vorratsbehälter 107 gesaugt und durch die Zuführungsleitung 109 in die Breitstrahldüse 101 gedrückt wird. Die Halterung 113 weist auf der der Breitstrahldüse 101 abgekehrten Seite einen Zuführungsstutzen 115 auf, an dem eine Zuführungsleitung 116 vom Vorratsbehälter 117 für das flüssige Bindemittel angeschlossen ist. In der Halterung 113 sind Verbindungen zwischen den Zuführungsstutzen 115 und den Düsen 103 für das flüssige Bindemittel angeordnet. Aus dem Vorratsbehälter 117 wird das flüssige Bindemittel durch die Zuführungsleitung 116 in die Düsen 103 gedrückt, zweckmäßig mittels Preßluft oder dgl..At the end of the inlet nozzle 112, the wide jet nozzle 101 is closed, apart from the passage of the inlet nozzle 112. From the inlet nozzle 112 to the outlet opening 104, the wide jet nozzle 101 is designed in an arc shape, as can be seen from FIGS. 4 and 5. This design has the advantage that the jet of the granular filler emerges evenly distributed over the entire outlet opening 104 when the spraying device is held at an angle. The inner wall 105 can be shortened relative to the outer wall 106 at the outlet opening 104. The wide jet nozzle 101 is fastened in a holder 113 at the end opposite the outlet opening 104. A handle 114 is arranged on this holder 113. In addition to the wide jet nozzle 101, parallel to the longest axis, one or more nozzles 103 for the liquid binder are arranged, through which the liquid binder is injected into the jet of the granular filler. It is advantageous to provide a nozzle 103 for the liquid binder on the outer wall 106 as well as on the inner wall 105, expediently in the center. The outlet ends of these nozzles 103 for the liquid binder are also expediently designed as wide-jet nozzles. The longest axis of the outlet openings of this nozzle 103 for the liquid binder should lie parallel to the longest axis 102 of the outlet opening 104 of the wide jet nozzle 101 for the granular filler. The outlet openings of the nozzles 103 lie approximately at the level of the free ends of the outer wall 106 or the inner wall 105. They are designed and arranged such that the liquid binder is distributed as uniformly as possible in the beam F of the granular substance üll-. The inlet 109 for the granular filler is connected to the inlet nozzle 112 of the wide jet nozzle 101. This granular filler is located in a storage container 107, which tapers downwards and has at least one bottom sloping towards the center. A horizontal pipe socket 110 is arranged under the bottom of the storage container 107, the interior of which is connected to the interior of the storage container 107. The feed line 109 to the wide jet nozzle 101 is connected to one end of this stirrup nozzle 110. At the other end of the connection piece 110 there is a blower 108, with which the granular filler is sucked out of the storage container 107 and pressed through the feed line 109 into the wide jet nozzle 101. The holder 113 has on the side facing away from the wide jet nozzle 101 a feed pipe 115, to which a feed line 116 from the reservoir 117 for the liquid binder is connected. Connections between the supply nozzle 115 and the nozzles 103 for the liquid binder are arranged in the holder 113. The liquid binder is pressed out of the storage container 117 through the supply line 116 into the nozzles 103, expediently by means of compressed air or the like.

Um auch bei Bindemitteln unterschiedlicher Konsistenz und/ oder bei unterschiedlichen Temperaturen mit der Vorrichtung einwandfrei arbeiten zu können, ist es zweckmäßig, die Austrittsenden der Düsen 103 verstellbar zu gestalten. Zweckmäßig ist es auch, den körnigen Füllstoff vor dem Auftragen auf das Mauerwerk oder dgl. zu erwärmen, damit das Bindemittel möglichst schnell abbindet. Dieserhalb ist es möglich, vor dem Gebläse 108, mit welchem die Luft in den Stutzen 110 gedrückt wird, eine Heizvorrichtung vorzusehen, in der die Förderluft erwärmt wird. Von der Förderluft wird dann die Wärme auc den körnigen Füllstoff übertragen und dieser so erwärmt.In order to be able to work properly with the device even with binders of different consistency and / or at different temperatures, it is expedient to make the outlet ends of the nozzles 103 adjustable. It is also expedient to heat the granular filler before applying it to the masonry or the like, so that the binder sets as quickly as possible. For this reason, it is possible to place a heating device in front of the fan 108, with which the air is pressed into the socket 110 watch in which the conveying air is heated. The heat is then transferred from the conveying air to the granular filler, which heats it up.
