Abstract

A method is proposed for coating formwork panels (2) of plywood for concrete formwork which makes the panels more resistant and able to be used twice as often as hitherto. A primer coat is applied in liquid form to the bare panels (2) and is made to set, and then a top coat is applied by blowing fine-grained hard granules onto a sprayed-on, still liquid lower top coat, immediately following this by spraying on an upper top coat of the same coating product as the lower top coat, after which the top coat as a whole is made to set. For applying the top coat, all the formwork elements (8) are passed under a multiple spray head (14) which runs back and forth in the transverse direction and on which a first spray nozzle (19), a blowing tube (18) for the granules and a second spray nozzle (17) are arranged at equal intervals one after the other in the running direction (13). The two liquid coating products are prepared according to specifically prescribed formulations. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zur Beschichtung von Schalplatten, insbesondere aus Sperrholz, für Betonschalungen und die dabei verwendeten Werkstoffe. Derartige Schalplatten sind sehr häufig in einen metallenen Rahmen eingebaut und bilden mit diesem zusammen sog. Schalelemente, welche mit geeigneten Verbindungsorganen versehen sind und mit deren Hilfe große Schalflächen bilden, wie sie im Betonhoch- und -tiefbau erforderlich sind.The invention relates to a method for coating formwork panels, in particular made of plywood, for concrete formwork and the materials used. Formwork panels of this type are very often installed in a metal frame and together form what are known as formwork elements, which are provided with suitable connecting elements and with the aid of which form large formwork surfaces, as are required in concrete building and civil engineering.

Die bekannten Schalplatten aus Sperrholz, die eine Dicke zwischen 12 und 30 mm haben und aus einer Vielzahl miteinander verleimter Schichten unterschiedlicher Faserrichtung bestehen, haben eine braune glatte und vielfach glänzende Oberfläche, um sich möglichst leicht von dem erhärteten Beton abzulösen. Trotzdem haftet Beton nach mehrmaligen Einsätzen der Schalplatte zunehmend an dieser fest und die Reinigung der Platten wird arbeitsintensiv. Nach maximal dreißig bis vierzig Einsätzen müssen diese Schalplatten außer Betrieb genommen werden und häufig genug ist eine Aufarbeitung und Neubeschichtung nicht mehr möglich.The known plywood formwork panels, which have a thickness between 12 and 30 mm and consist of a large number of layers of different fiber directions glued together, have a brown, smooth and often glossy surface in order to detach themselves as easily as possible from the hardened concrete. Nevertheless, concrete sticks after repeated use of the formwork panel increasingly stuck to it and cleaning the panels becomes labor-intensive. After a maximum of thirty to forty uses, these formwork panels must be taken out of operation and often enough, refurbishing and re-coating is no longer possible.

Der Erfindung liegt die Aufgabe zugrunde, die Standfestigkeit von Schalplatten zu erhöhen und deren Reinigung, sofern überhaupt erforderlich, zu erleichtern.The invention has for its object to increase the stability of formwork panels and to facilitate their cleaning, if necessary at all.

Diese Aufgabe wird erfindungsgemäß durch ein Beschichtungsverfahren gelöst, das die kennzeichnenden Merkmale des Anspruchs 1 aufweist. Auf diese Weise beschichtete Schalplatten haben, obwohl ihre Oberfläche nicht glatt ist, sondern sich infolge der Granulateinschlüsse rauh anfühlt, eine wesentlich höhere Standfestigkeit von achtzig und mehr Einsätzen. Die Oberflächenschicht haftet besser auf dem Holz, löst sich besser vom Beton ab und ist mit Schabewerkzeugen wesentlich leichter zu reinigen. Ein weiterer Vorteil liegt darin, daß die Oberflächenschicht verhältnismäßig zäh ist und im Gegensatz zu den bekannten Schalplatten beim Einschlagen eines Nagels an der Einschlagstelle nicht abblättert. Auch die Wasserdurchlässigkeit ist im Vergleich zu bekannten Schalplatten wesentlich geringer, so daß die beschichteten Platten eine geringere Neigung zum Aufquellen haben.According to the invention, this object is achieved by a coating method which has the characterizing features of claim 1. Formwork panels coated in this way, although their surface is not smooth but feels rough due to the granulate inclusions, have a significantly higher stability of eighty or more uses. The surface layer adheres better to the wood, detaches better from the concrete and is much easier to clean with scraping tools. Another advantage is that the surface layer is relatively tough and, in contrast to the known formwork panels, does not peel off when a nail is hammered in at the point of impact. The water permeability is also significantly lower than that of known formwork panels, so that the coated panels have less tendency to swell.

Die Grundschicht wird mit Vorteil in der Weise aufgebracht, daß man den flüssigen Beschichtungswerkstoff durch einen horizontalen Schlitz laufen läßt und dadurch einen Flüssigkeitsvorhang bildet, durch den die Platten in horizontaler Richtung durchgeführt werden. Die Platten sollten nach dem Aushärten der Grundschicht gewendet und sodann in gleicher Weise auf der Rückseite beschichtet werden. Das Aushärten kann bei den unten noch zu erläuternden Werkstoffen durch den Weitertransport der Platten in einem Schrank, in dem eine besonders hohe Luftfeuchtigkeit aufrecht erhalten wird, beschleunigt werden.The base layer is advantageously applied in such a way that the liquid coating material is run through a horizontal slot and thereby forms a liquid curtain through which the plates are passed in the horizontal direction. The plates should be turned after the base layer has hardened and then coated on the back in the same way. In the case of the materials to be explained below, curing can be accelerated by further transport of the plates in a cabinet in which a particularly high level of air humidity is maintained.

Zum Aufbringen der Deckschicht läßt man die Platten vorzugsweise unter einem in Querrichtung hin und hergehenden Mehrfachspritzkopf durchlaufen, an dem in Laufrichtung der Platten in gleichen Abständen hintereinander eine erste Spritzdüse, ein Blasrohr für das Granulat und eine zweite Spritzdüse angeordnet sind. Besonders gute Ergebnisse lassen sich dadurch erzielen, daß die Platten in Schritten entsprechend dem genannten Abstand weitertransportiert werden und daß jeweils dann ein Transportschritt erfolgt, wenn der Mehrfachspritzkopf im Bereich der Plattenseitenränder umkehrt. Somit kommen in ein und demselben quer verlaufenden streifenförmigen Bereich der Platte die drei Düsen des Spritzkopfes nacheinander zum Einsatz.To apply the cover layer, the plates are preferably passed under a multiple spray head which is reciprocating in the transverse direction and on which a first spray nozzle, a blow pipe for the granules and a second spray nozzle are arranged at equal intervals in the running direction of the plates. Particularly good results can be achieved in that the plates are transported in steps corresponding to the distance mentioned and in that a transport step is carried out in each case when the multiple spray head reverses in the region of the plate side edges. Thus, the three nozzles of the spray head are used one after the other in one and the same transverse strip-shaped area of the plate.

Sofern die Platten mit einem Metallrahmen als sog. komplette Schalelemente eingesetzt werden sollen, wird vorgeschlagen, daß die Platten nach dem beidseitigen Aufbringen der Grundschicht auf Maß geschnitten, an den Schnittkanten, insbesondere mit dem Beschichtungswerkstoff der Grundschicht, versiegelt, in einen zugehörigen Rahmen mit erhöhtem umlaufendem Rand eingelegt und an diesem durch Schrauben, Nieten oder dgl. mit Senkkopf befestigt werden, daß die Fugen zwischen den Platten und den umlaufenden Rändern sowie die durch die Senkköpfe entstandenen Vertiefungen mittels einer selbsthärtenden Spachtelmasse verspachtelt werden und daß auf die so entstandenen Schalelemente an der benutzten Seite die Deckschicht aufgebracht wird.If the panels with a metal frame are to be used as so-called complete formwork elements, it is proposed that the panels be cut to size after the two-sided application of the base layer, sealed at the cut edges, in particular with the coating material of the base layer, in an associated frame with an elevated the surrounding edge and fastened to it by screws, rivets or the like used the top layer is applied.

Was die Zusammensetzung der Beschichtungswerkstoffe angeht, so ist zwischen einem Gemisch für die Grundschicht und einem Gemisch für die Deckschicht zu unterscheiden. Diese Gemische werden vorzugsweise aus den in den Ansprüchen 6 und 7 angegebenen Bestandteilen zusammengerührt, wobei das Mengenverhältnis wenigstens ungefähr den dort gemachten Angaben entsprechen sollte. Die Gemische haben dann eine Konsistenz, die es erlaubt, einen frei fallenden zusammenhängenden Flüssigkeitsvorhang zum Aufbringen der Grundschicht zu erzeugen bzw. den ebenfalls flüssigen Beschichtungswerkstoff für die Deckschicht mit Düsen unter Druck zu versprühen. Wie schon erwähnt wird in die Deckschicht außer dem zu versprühenden Beschichtungswerstoff ein Granulat eingebracht und zwar vorzugsweise ein sehr feinkörniges Pulver aus Aluminiumsilikat-Hohlkugeln, die eine mittlere Korngröße von 0,01 bis 0,35 mm haben. Dieses Pulver kann pneumatisch gefördert und durch ein geeignetes Rohr bzw. eine Düse ausgeblasen und dadurch feinst verteilt werden.As far as the composition of the coating materials is concerned, a distinction must be made between a mixture for the base layer and a mixture for the cover layer. These mixtures are preferably stirred together from the constituents specified in claims 6 and 7, the quantitative ratio should correspond at least approximately to the information given there. The mixtures then have a consistency which makes it possible to produce a free-falling, coherent liquid curtain for applying the base layer or to spray the likewise liquid coating material for the cover layer with nozzles under pressure. As already mentioned, in addition to the coating material to be sprayed, a granulate is introduced into the cover layer, preferably a very fine-grained powder made of hollow aluminum silicate balls, which have an average grain size of 0.01 to 0.35 mm. This powder can be conveyed pneumatically and blown out through a suitable pipe or nozzle and thereby finely distributed.

Ausführungsbeispiele der Erfindung werden nachfolgend in Tabellenform und anhand der Zeichnung näher erläutert. Im einzelnen zeigt

  • Tabelle A zwei Gemische A1 und A2 mit unterschiedlichen Mengenverhältnissen für die Grundschicht,
  • Tabelle B zwei Gemische B1 und B2 mit unterschiedlichen Mengenverhältnissen für die Deckschicht,
  • Figur 1 eine schematische Seitenansicht der Anordnung zum Aufbringen der Grundschicht,
  • Figur 2 einen Teilquerschnitt eines Schalungselements in größerem Maßstab und
  • Figur 3 eine schematische Seitenansicht einer Anordnung zum Aufbringen der Deckschicht.
Exemplary embodiments of the invention are explained in more detail below in tabular form and with reference to the drawing. In detail shows
  • Table A two mixtures A1 and A2 with different quantitative ratios for the base layer,
  • Table B two mixtures B1 and B2 with different proportions for the top layer,
  • FIG. 1 shows a schematic side view of the arrangement for applying the base layer,
  • Figure 2 shows a partial cross section of a formwork element on a larger scale and
  • Figure 3 is a schematic side view of an arrangement for applying the cover layer.

Die Gemische A1 und A2 sowie B1 und B2 haben sich in der Praxis bewährt. Die jeweiligen Unterschiede in den Mengenverhältnissen geben einen Hinweis darauf, wie groß etwa die Schwankungsbreite der in den Ansprüchen angegebenen Mengenverhältnisse ist.The mixtures A1 and A2 as well as B1 and B2 have proven themselves in practice. The respective differences in the quantitative ratios give an indication of how large the range of fluctuation of the quantitative ratios specified in the claims is.

Zunächst wird eines der Gemische nach Tabelle A für die Grundschicht in einem Faß angerührt und dann gemäß Fig. 1 verarbeitet.First, one of the mixtures according to Table A for the base layer is stirred in a barrel and then processed according to FIG. 1.

Diese Figur zeigt oben den schematischen Querschnitt einer Vorratsrinne 1, deren Länge mindestens gleich der Breite der zu beschichtenden Schalplatten 2 ist. Die horizontal gelagerte Rinne hat unten einen geradlinigen schmalen Längsschlitz, durch welchen das bevorratete flüssige Gemisch als lückenloser Flüssigkeitsvorhang 3 ausläuft. Für den Fall, daß keine Schalplatten 2 vorhanden sind, ist unten eine Auffangrinne 4 vorgesehen, welche dann den Flüssigkeitsvorhang wie strichpunktiert angedeutet aufnimmt und in einen Sammelbehälter 5 ableitet. Zum Aufbringen der Grundschicht werden die Schalplatten 2 nacheinander auf einer Rollenbahn mit angetriebenen Rollen 6 in Richtung des Pfeiles 7, d. h. senkrecht zum Flüssigkeitsvorhang 3 mit gleichmäßiger Geschwindigkeit unter der Vorratsrinne 1 durchgeführt. Der Flüssigkeitsvorhang legt sich somit auf den Schalplatten 2 ab und diese gelangen anschließend in eine möglichst gekapselte Transportanlage, in welcher eine hohe Luftfeuchtigkeit besteht, um den Aushärtevorgang zu beschleunigen. Nach etwa einer Stunde ist die Grundschicht so weit ausgehärtet, daß die Platten gewendet und mit der Unterseite nach oben durch die Anlage gefahren werden können.This figure shows the schematic cross section above of a storage channel 1, the length of which is at least equal to the width of the formwork panels 2 to be coated. The horizontally mounted trough has a straight, narrow longitudinal slot below, through which the stored liquid mixture runs out as a complete liquid curtain 3. In the event that there are no formwork panels 2, a collecting channel 4 is provided at the bottom, which then receives the liquid curtain as indicated by dash-dotted lines and discharges it into a collecting container 5. To apply the base layer, the formwork panels 2 are carried out one after the other on a roller conveyor with driven rollers 6 in the direction of the arrow 7, ie perpendicular to the liquid curtain 3 at a uniform speed under the storage channel 1. The liquid curtain is thus deposited on the formwork panels 2 and these then pass into a transport system which is encapsulated as possible and in which there is high atmospheric humidity in order to accelerate the curing process. After about an hour, the base layer has hardened to such an extent that the panels can be turned and driven through the system with the underside facing upwards.

Die somit auf beiden Seiten grundbeschichteten Schalplatten werden nun auf Maß zugeschnitten, so daß sie in die üblichen Stahlrahmen 8 von Schalelementen passen. Ein Beispiel zeigt Fig. 2. Der Rahmen 8 besteht aus einem Rechteck-Hohlprofilrohr, das an einer Seite einen erhöhten Rand 9 aufweist, welcher das Schalelement ringsum einfaßt und die Schnittkanten der Schalplatte 2 abdeckt. Trotzdem werden, um das Eindringen von Feuchtigkeit zu verhindern, die Schnittkanten beispielsweise durch Auftragen des Beschichtungswerkstoffs nach Tabelle A versiegelt, bevor die Platten in die Rahmen eingelegt werden. Meist steht der Rand 9 ein wenig über die Plattendicke hinaus. Nun werden die Schalplatten 2 mit Hilfe von Senkschrauben oder vorzugsweise durch Einschießen von Bolzen 10 an dem Rahmen befestigt.The formwork panels thus coated on both sides are now cut to size so that they fit into the usual steel frames 8 of formwork elements. An example is shown in FIG. 2. The frame 8 consists of a rectangular hollow profile tube which has a raised edge 9 on one side, which surrounds the formwork element all around and covers the cut edges of the formwork panel 2. Nevertheless, in order to prevent the ingress of moisture, the cut edges are sealed, for example by applying the coating material according to Table A, before the panels are inserted into the frame. Usually the edge 9 protrudes a little beyond the plate thickness. Now the formwork panels 2 are fastened to the frame by means of countersunk screws or preferably by shooting in bolts 10.

Ist dies geschehen, so werden die Fugen 11 zwischen den Schalplatten und dem Rand 9 sowie die durch die Befestigungselemente verursachten Vertiefungen mittels einer selbsthärtenden Spachtelmasse sauber verspachtelt. Bewährt hat sich hierfür eine Einkomponenten-Polyurethan-­Dichtungsmasse, die unter der Kennzeichnung SIKAFLEX 11 FC von der Firma Roland Schmid Baukunststoffe GmbH, 7321 Albershausen, in den Handel gebracht wird.Once this has been done, the joints 11 between the formwork panels and the edge 9 and the depressions caused by the fastening elements are properly filled using a self-curing filler. A one-component polyurethane sealant, which is marketed under the label SIKAFLEX 11 FC by Roland Schmid Baukunststoffe GmbH, 7321 Albershausen, has proven successful.

Fig. 3 zeigt die Weiterbehandlung der zusammengesetzten Bauelemente. Diese werden unmittelbar aneinanderstossend mittels einer geeigneten Fördereinrichtung, im Beispiel einem Bandförderer 12, in Richtung des Pfeiles 13 mit einer Schrittlänge von 20 cm schrittweise horizontal bewegt. Fig. 3 zeigt die Rahmen 8 von der Seite gesehen. Die Platten 2 liegen oben. Über den Bauelementen bewegt sich ein Wagen 14 hin und her. Er hat Rollen 15, die in entsprechenden Führungsschienen 16 laufen und diese sind über dem Bandförderer befestigt. Der Wagen trägt drei nach unten gerichtete Düsen 17, 18 und 19, die über zwei Schlauchleitungen 20 und 21 versorgt werden. Die Düsen sind in Bewegungsrichtung 13 der Schalelemente im gegenseitigen Abstand von 20 cm angeordnet. Die vordere und hintere Düse 17 bzw. 19 ist an der Schlauchleitung 20 angeschlossen und die Schlauchleitung 21 versorgt die Düse 18. Die Düsen 17 und 19 versprühen eine Beschichtungsmasse nach der Tabelle B, während aus der Düse 18 ein feiner Staub aus Aluminiumsilikat-Hohlkugeln einer mittleren Korngröße von 0,01 bis 0,35 mm ausgeblasen wird. Als besonders geeignet erwies sich ein derartiges Pulver, das unter der Kennzeichnung STIFF 100/0 von der Firma Schwarzwälder Textil-Werke Heinrich Kautzmann GmbH, 7623 Schenkenzell, in den Handel gebracht wird.3 shows the further treatment of the assembled components. These are moved horizontally in steps in the direction of arrow 13 with a step length of 20 cm, directly abutting one another by means of a suitable conveyor device, in the example a belt conveyor 12. Fig. 3 shows the frame 8 seen from the side. The plates 2 are on top. A carriage 14 moves back and forth over the components. He has roles 15 that in corresponding guide rails 16 run and these are fastened over the belt conveyor. The carriage carries three downwardly directed nozzles 17, 18 and 19, which are supplied via two hose lines 20 and 21. The nozzles are arranged in the direction of movement 13 of the formwork elements at a mutual distance of 20 cm. The front and rear nozzles 17 and 19 are connected to the hose line 20 and the hose line 21 supplies the nozzle 18. The nozzles 17 and 19 spray a coating material according to Table B, while from the nozzle 18 a fine dust made of hollow aluminum silicate balls average grain size of 0.01 to 0.35 mm is blown out. Such a powder, which is marketed under the label STIFF 100/0 by the company Schwarzwälder Textil-Werke Heinrich Kautzmann GmbH, 7623 Schenkenzell, has proven to be particularly suitable.

Die Bewegung des Wagens 14 ist mit der Vorwärtsbewegung der Schalelemente so koordiniert, daß letztere immer dann einen Schritt machen, wenn der Wagen 14 in den Seitenbereichen, vorzugsweise außerhalb der Schalplatten 2, seine Bewegungsrichtung umkehrt. Betrachtet man einen Querstreifenbereich der Platten, so wird dieser zunächst von der Düse 19 mit der Beschichtungsflüssigkeit besprüht, sodann wird auf die noch flüssige untere Deckschicht über die Düse 18 das Pulver aufgeblasen und schließlich werden die an der unteren Deckschicht haftenden Aluminiumsilikat-­Partikel von der Düse 17 übersprüht, so daß sie schließlich fest in der Deckschicht eingebettet sind. Nachdem die Deckschicht an der Luft ausgehärtet ist, sind die Schalelemente fertig und können in Benutzung genommen werden.The movement of the carriage 14 is coordinated with the forward movement of the formwork elements so that the latter always take a step when the carriage 14 reverses its direction of movement in the side areas, preferably outside the formwork panels 2. If one considers a transverse strip area of the plates, this is first sprayed with the coating liquid by the nozzle 19, then the powder is inflated onto the still liquid lower cover layer via the nozzle 18 and finally the aluminum silicate particles adhering to the lower cover layer are released from the nozzle 17 sprayed, so that they are finally firmly embedded in the top layer. After the surface layer has hardened in the air, the formwork elements are ready and can be used.

Die Anordnung der verschiedenen Schichten ist im rechten Teil der Fig. 2 in übertriebener Dicke verdeutlicht. Die auf beiden Seiten angebrachten Grundschichten sind mit A und die nur an der oberen, benutzten Seite angebrachte Deckschicht ist mit B bezeichnet. Rezepte für diese Schichten sind in den entsprechenden Tabellen A und B aufgeführt. Die Deckschicht B hat infolge der Aluminiumsilikat-Einschlüsse eine rauhe Oberfläche, die sich glättet, wenn man mit einem harten Gegenstand darauf reibt. Das könnte darauf zurückzuführen sein, daß die Hohlkugeln einbrechen, was jedoch die außerordentliche Verschleißfestigkeit der Schicht nicht beeinträchtigt.The arrangement of the different layers is illustrated in the right part of FIG. 2 in an exaggerated thickness. The base layers on both sides are marked with A and the cover layer only on the upper, used side is marked with B. Recipes for these layers are listed in the corresponding tables A and B. The top layer B has a rough surface due to the aluminum silicate inclusions, which smoothes out when rubbed with a hard object. This could be due to the fact that the hollow spheres collapse, but this does not impair the extraordinary wear resistance of the layer.

Eine zweckmäßige Dicke der beschriebenen Schichten ergibt sich, wenn für die Grundschicht etwa 0,2 l/m² des entsprechenden Beschichtungswerkstoffs verarbeitet werden und für die Deckschicht (d. h. für die untere und obere zusammen) etwa 0,3 l/m² Beschichtungswerkstoff und etwa 21 g/m² Aluminiumsilikat-Hohlkugeln verarbeitet werden.
