Holzbauelemente beschrieben, bei denen im Zugbe- 30 Wooden construction elements described in which in the tensile 30 reich kunststoffeetränkte Glasfasern unmittelbar mit Hierzu 1 Blatt ZeichnungenRichly plastic-soaked glass fibers immediately with 1 sheet of drawings den Holzteilen verbunden sind. Der Nachteil dieser the wooden parts are connected. The disadvantage of this Bauweise besteht darin, daß der Aufbau verschiedenartiger Konstruktionen aus einzelnen Holzelementen und harzgetränkten Glasfasern fertigungstechnisch schwierig ist, da letztere nur in situ — d. h. ohne Vorfertigung einzelner Zugelemente — eingebaut werden können.Construction consists in the fact that the construction of various structures from individual wooden elements and resin-impregnated glass fibers is difficult to manufacture, since the latter is only possible in situ - i.e. H. without prefabrication individual tension elements - can be installed. Aufgabe der Erfindung ist, einen tragenden Verstärkungsschichtstoff der bezeichneten Art zu finden, der in einem Holzleimbinder als vorgefertigtes Element durch übliche Holzleime mit den benachbarten Holzelementen verbunden werden kann.The object of the invention is to provide a load-bearing reinforcing laminate of the specified type, which is carried out in a laminated wood beam as a prefabricated element Usual wood glue can be connected to the neighboring wooden elements. Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein Kern aus den in der Harzmatrix eingebetteten Fasern mindestens auf einer Seite mit einer leimfähigen Deckschicht über das Harz verbunden ist, welches aber die Deckschicht nicht vollständig durchdrungen hat.The object is achieved according to the invention in that a core made of the embedded in the resin matrix Fibers at least on one side with an adhesive cover layer is connected via the resin, but which has not completely penetrated the top layer. Der erfindungsgemäße Verstärkungsschichtstoff läßt sich problemlos mit der Deckschicht aus Holz verbinden. Die übliche Technik im Holzbau, das Verkleben der Holzleimbinder mit Klebern auf Harnstoff-Melamin-Basis ist mit dem erfindungsgemäßen Verstärkungsschichtstoff ohne Änderung möglich. Dieser kann mit den zugelassenen üblichen Leimen verarbeitet werden. Als Kern sind mit in gleicher Richtung verlaufenden Glas· oder Kohlenstoff-Fasern verstärkte Kunststoffkörper geeignet. Als Deckschichten kommen neben Holz, Pappe, Vliese oder Kraftpapiere auf Zellulosebasis in Frage. Zweckmäßig weist die Deckschicht eine Sperrschicht auf, zum Beispiel Sperrholz. Mit solchen Deckschichten mit mindestens einer Sperrschicht läßt sich in einfacher und sicherer Weise erreichen, daß einerseits der Kern mit der Deckschicht gut verbunden ist und andererseits aber die Deckschicht nicht durchimprägniert ist, was den Verbund der Deckschicht mit Holz erschweren würde, weil es die Holzleime in ihrer Reaktion stören könnte.The reinforcing laminate according to the invention can be connected to the top layer made of wood without any problems. The usual technique in timber construction, gluing the glued wood beams with adhesives based on urea-melamine is possible with the reinforcing laminate according to the invention without change. This can with the approved common glues are processed. As a core are with running in the same direction Glass or carbon fiber reinforced plastic bodies are suitable. As top layers come next Wood, cardboard, fleece or cellulose-based kraft paper are possible. The cover layer expediently has a Plywood, for example. With such top layers with at least one barrier layer leaves achieve in a simple and reliable manner that on the one hand the core is well connected to the cover layer and on the other hand, however, the top layer is not fully impregnated, which is what the composite of the top layer with Wood would make it more difficult because it could interfere with the reaction of the wood glues.
