Abstract

A method of making boards or panels for concrete shuttering, predominantly from wood, consists of pressing a laminated structure comprising a central core of chipboard and, (symmetrically) each side of the core thin layers of timber with facing sheets of moisture-impermeable material, esp. hot-setting phenolic paper. Each thin timber layer is pref. made of >=2 sheets of veneer with their grain directions crossing.

Description

Bezeichnung: Verfahren zur Herstellung von Schalungsplatten und Schalungsplatten nach diesem Verfahren Die Erfindung betrifft ein Verfahren zur Herstellung von im wesentlichen aus Holz bestehenden Schalungsplatten für Betonverschalungen oder dgl. sowie eine nach diesem Verfahren hergestellte Schalungsplatte.Description: Process for the production of shuttering panels and shuttering panels according to this process The invention relates to a process for the production of im essentially made of wood formwork panels for concrete formwork or the like. as well as a shuttering panel produced by this method.

Allgemein werden an Schalungsplatten hinsichtlich der mechanischen Festigkeit sowie die ihrer Feuchtigkeitsunempfindlichkeit sehr hohe Anforderungen gestellt Um diesen Anforderungen einigermassen gerecht zu werden9 verwendete man bisher hierfür ausschliesslich Sperrholz oder mehrlagige Tischlerplatten, die verhältnismässig teuer sind.In general, formwork panels with regard to the mechanical Strength as well as their insensitivity to moisture are very high requirements posed In order to meet these requirements to some extent9 one used so far only plywood or multi-layer blockboard, which is relatively are expensive.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu entwickeln, mit dem Schalungsplatten aus weniger teuererem Werkstoffs jedoch mit mindestens etwa gleiches Qualität herstellbar sind.The invention is based on the object of developing a method with the formwork panels made of less expensive material, however, with at least about the same quality can be produced.

Das erfindungsgemässe Verfahren ist dadurch gekennzeichnet, dass ein Schichtgebilde bestehend aus einer aus einer Spanplatte gebildeten Kernschicht, beiderseits daran angeordneten dünnen Holzschichten und je einer die Holzschicht bedeckenden Abdeckschicht aus feuchtigkeitsundurchlässigem Werkstoff zu einem einstückigen Verbundkörper verpresst wird.The inventive method is characterized in that a Layer structure consisting of a core layer formed from a chipboard, thin layers of wood arranged on both sides and one layer of wood each covering cover layer made of moisture-impermeable material into a one-piece Composite body is pressed.

Eine Spanplatte ist bek@nntlich ein verhältnismässig billiges Produ@@ aus Holzebfällen. Sie hat die nachteilige Eigenschaft,einer geringen mechanischen Festigkeit, insbesondere in der Schalungstechnik gegenüber solchen Kräften, die vom gegossenen @eton ausgeübt werden.Chipboard is known to be a relatively cheap product. from wood chips. It has the disadvantage of being poor in mechanical properties Strength, especially in formwork technology, against forces that exercised by the cast @eton.

Durch die auf die Spanplatte aufgebrachten Holzschichten erhält der erfindungsgemässe Verbundkörper eine hohe mechanische Festigkeit, die, wis sich überraschender@eise herausgestellt hat, derjenigen der bekannten Schalung@-platten nicht nachst@ht.The layers of wood applied to the chipboard give the composite bodies according to the invention have a high mechanical strength, which is known surprisingly, that of the well-known formwork panels not next @ ht.

Vorteilhaft werden mindestens je zwei Holzschichten bestehend aus Furnieren verwen@@t@ deren Faserrichtungen einander kreuzen. Hierdurch werden Zugerscheinungen und Verwerfungen in der ei@en @@er anderen Richtung in an sich bekannter Weise vermi@@@@.It is advantageous to each consist of at least two layers of wood Use veneers whose grain directions cross each other. This causes drafts and faults in the other direction in a manner known per se vermi @@@@.

Ein weiteres vorteilhaftes Merkmal des erfindungsgemässen Verfahrens besteht derin, dass als Abdeckschicht warmhärtendes Phen@lpapier verwendet wird.Another advantageous feature of the method according to the invention is that thermosetting phenolic paper is used as the cover layer.

Das erfindungsgemässe Verfahren kann weitgehend automatisch durchgeführt werden. Vorteilhaft wird das Schichtgebilde warm gepresst.The method according to the invention can be carried out largely automatically will. The layer structure is advantageously hot-pressed.

Die Erfindung betrifft gleichermassen auch die nach dem vorgenannten Verfahren verfertigte Schalungsplatte.The invention also relates to that according to the aforementioned Process manufactured formwork panel.

In der Zeichnung ist ein Teil einer solchen Schalungsplette perspektivisch und teilweise im Schnitt wiedergegeben.In the drawing, part of such a formwork panel is in perspective and partly reproduced in section.

Auf einer Abdeckschicht 1' aus feuchtigkeits@b@@isenden Werkstoff, zum Beispiel einem warmhärt@ndem Phenolpepier, sind zwei dünne Holzschichten 2' und 3' aus Furnier angeordnet, deren Faserrichtungen einander kreuzen. Für diese Holzschichten kann billiges Furnierholz verwendet werden.On a cover layer 1 'made of moisture-proof material, for example a thermosetting phenol paper, two thin layers of wood are 2 ' and 3 'made of veneer, the fiber directions of which cross each other. For this Layers of wood, cheap plywood can be used.

Den Kern des dargestellten Verbundkörpers bildet eine Spanplatte 4 die bekanntlich hinsichtlich ihrer Holzfasern richtungsneutral ist. Auf dieser Spenplatte liegen wieder zwei dünne Holzschichten 3 und 2 mit einander kreuzenden Fasern 6 und 5. Auf der obersten Holzschicht 2 befindet sich wieder etne Abdeckschicht 1 aus feuchtigkeitsabweisendem Werkstoff z.B. Phenolpapier.A chipboard 4 forms the core of the composite body shown which is known to be directionally neutral with regard to its wood fibers. On this cutting plate there are again two thin layers of wood 3 and 2 crossing each other Fibers 6 and 5. On top of the wood layer 2 there is another cover layer 1 made of moisture-repellent material e.g. phenolic paper.

Die Anzahl der Holzechichten 2,3 ist nicht auf die dergestellte Anzahl beschränkt. Sie kann geringer odor höher sein Je nach der Art der erforderlichen Festigkeit.The number of wood layers 2, 3 is not the number shown limited. It can be lower or higher depending on the nature of the required Strength.
