Abstract

Parts made of wood are joined together by two coats of glue (6) with a layer of elastically deformable material between the two coats of glue. The two wooden parts are joined together with direction of the grain in the one part being different from the direction of the grain in the other part. The elastic material may be formed by a layer of plastics foam or a layer of cellular rubber (4). Wooden constructions of this type have equal strength in all directions in the planes of the layers but the elastic layers allow the outer wooden layers to expand or contract relative to the inner wooden layers and so prevent cracking of the outer layers. USE/ADVANTAGE - Glued joints for wooden parts which permit limited relative movements between and parts.

Description

Die Erfindung betrifft ein Verfahren zur Verbindung von Holz­ teilen sowie eine Holzkonstruktion.The invention relates to a method for joining wood share as well as a wooden structure.

Holz ist ein natürlicher Werkstoff, der aufgrund seiner wert­ vollen Eigenschaften auf vielen Gebieten eingesetzt wird. Auf­ grund der Anisotropie weist Holz in den drei Hauptachsrich­ tungen verschiedene Festigkeits-, Elastizitäts-, Quell- und Schwindeigenschaften auf. So quillt und schrumpft Holz in Faserrichtung bedeutend weniger als quer zur Faser. Diese Eigenschaften müssen bei der Verarbeitung berücksichtigt werden. Verbindet man Holz mit verschiedener Faserrichtung, wie es beispielsweise bei der Herstellung von Sperrholz ge­ schieht, so können bei mehrlagigen dünnen Holzschichten die Schwind- und Quellbewegungen dadurch aufgefangen werden. Ver­ leimt man Schichten gegenläufiger Faserrichtung miteinander, so behindern sie sich jeweils bei der Ausdehnung quer zur Faserrichtung. Die Absperrung läßt sich jedoch nur dort erreichen, wo eine vollflächige feste Bindung der Schichten vorhanden ist.Wood is a natural material because of its value full properties is used in many areas. On Due to the anisotropy, wood points in the three main axes different strength, elasticity, swelling and Shrinkage properties. So wood swells and shrinks Grain direction significantly less than across the grain. These Properties must be taken into account during processing will. If you connect wood with different grain, such as ge in the manufacture of plywood looks, so can with multilayered thin layers of wood Shrinkage and swelling movements are thereby absorbed. Ver glue layers of opposite fiber direction together, so they hinder each other in the expansion across Grain direction. The barrier can only be found there achieve where a full-surface firm binding of the layers is available.

Bei mehrschichtig aufgebauten, verleimten Holzkonstruktionen, z. B. bei Rahmen mit beidseitiger Beplankung aus Holz oder Holzwerkstoffen, tritt das Problem auf, daß die äußeren Holz­ teile an den Stellen, wo sie miteinander verleimt sind, sich nicht ausdehnen oder schwinden können, während die Teile, die nicht fixiert sind, arbeiten können. Es besteht daher die Gefahr, daß die Holzteile an den Stellen, wo sie fixiert sind, durch Quellen oder Schwinden reißen, da sie nicht nach­ geben können.In the case of multi-layer, glued wooden structures, e.g. B. for frames with double-sided planking made of wood or Wood materials, the problem arises that the outer wood divide at the places where they are glued together cannot expand or shrink while the parts that are not fixed, can work. There is therefore the Danger of the wooden parts in the places where they are fixed are tearing through swelling or shrinkage since they are not following can give.

Es war nun Aufgabe der Erfindung, ein Verfahren zur Verfügung zu stellen, mit dem Holzteile so verbunden werden können, daß die Verbindung die Formstabilität sichert, und bei dem gleichzeitig ein Reißen des Holzes verhindert wird. It was an object of the invention to provide a method to put, with which wooden parts can be connected so that the connection ensures dimensional stability, and in that at the same time preventing the wood from tearing.  

Diese Aufgabe wird gelöst durch ein Verfahren zur Verbindung von Holzteilen, das dadurch gekennzeichnet ist, daß man die Holz­ teile mit zwei Leimschichten und einer dazwischenliegenden Schicht aus elastischem Material verklebt.This object is achieved by a method for connecting Wooden parts, which is characterized in that the wood parts with two layers of glue and one in between Glued layer of elastic material.

Mit dem erfindungsgemäßen Verfahren gelingt es, Holzteile so zu verbinden, daß eine Bewegungsfähigkeit der Beplankung ge­ währleistet ist, andererseits aber die Formstabilität der Konstruktion gewahrt bleibt.With the method according to the invention, wooden parts can be made in this way to connect that a mobility of the planking ge is guaranteed, but on the other hand the dimensional stability of the Construction is preserved.

Erfindungsgemäß werden Holzteile durch Verleimen miteinander verbunden, wobei jedoch zwischen zwei Leimschichten eine Zwischenschicht aus elastischem Material vorgesehen wird. Das Verfahren eignet sich für alle Bereiche, wo Holzteile unter Erhaltung der Formstabilität miteinander verbunden werden. Unter Holzteilen im Sinne der Erfindung werden miteinander zu verbindende Körper aus Holz verstanden, wie Bretter, Balken, Platten, Rahmen usw. Insbesondere ist das erfindungsgemäße Verfahren geeignet zur Herstellung von Holzkonstruktionen, die aus einem Rahmen und darauf befestigten Platten, Brettern usw. als Beplankung bestehen.According to the invention, wooden parts are glued together connected, but one between two layers of glue Intermediate layer of elastic material is provided. The Process is suitable for all areas where wooden parts underneath Maintaining dimensional stability. Wood parts in the sense of the invention are used together connecting bodies made of wood understood, such as boards, beams, Panels, frames, etc. In particular, this is the invention Process suitable for the production of wooden structures, the one from a frame and attached panels, boards etc. exist as cladding.

Die Verbindung erfolgt durch eine Zwischenschicht aus zwei Schichten Leim und einer dazwischenliegenden Schicht aus elastischem Material.The connection is made by an intermediate layer of two Layers of glue and an intermediate layer elastic material.

Die Auswahl des Leims ist nicht kritisch; die auf diesem Gebiet bekannten Materialien sind hier geeignet. Allerdings muß der Leim so ausgewählt werden, daß er mit dem elastischen Material verträglich ist und eine dauerbeständige klebende Verbindung eingeht.The choice of glue is not critical; the on this Materials known in the art are suitable here. Indeed the glue must be selected so that it with the elastic Material is compatible and durable adhesive Connection comes in.

Das elastische Material bewirkt, daß zwischen den Holzteilen eine ausreichende Bewegungsfähigkeit besteht. Hierzu geeignete Materialien sind bekannt und können für den jeweiligen Zweck vom Fachmann durch Routineversuche leicht ermittelt werden. Geeignet sind Schaumstoffe aus Polymeren, wie Polyurethan, Polyvinyl­ chlorid und insbesondere Schaumgummi. Bevorzugt wird Kautschuk bzw. Zellkautschuk mit zelliger Struktur verwendet. Besonders bevorzugt ist Styrol-Butadien-Kautschuk und Nitril-Kautschuk.The elastic material causes between the wooden parts there is sufficient mobility. Suitable for this Materials are known and can be used for Experts can easily be determined by routine tests. Suitable  are foams made of polymers, such as polyurethane, polyvinyl chloride and especially foam rubber. Rubber is preferred or cellular rubber with a cellular structure. Especially styrene-butadiene rubber and nitrile rubber are preferred.

Da das elastische Material seine Elastizität auch nach dem Verleimen behalten muß, ist es bevorzugt, ein Schaumstoffmate­ rial zu verwenden, das geschlossene Poren aufweist, so daß es sich nicht mit Leim vollsaugen kann. Wenn ein Leim verwendet wird, der schnell abbindet und zuerst auf das Holz aufgetragen wird, so daß ein Eindringen in das Kunststoffmaterial nicht möglich ist, dann sind auch offenporige Schaumstoffe geeignet.Because the elastic material retains its elasticity even after the Must keep gluing, it is preferred to use a foam mat rial to use, which has closed pores, so that it can't soak up glue. When using glue that sets quickly and is first applied to the wood is so that no penetration into the plastic material is possible, then open-pore foams are also suitable.

Die Verbindung der Holzteile erfolgt, indem die Leimschichten entweder auf die miteinander zu verbindenden Holzteile oder auf die elastische Schicht auf beiden Seiten aufgetragen werden und anschließend in an sich bekannter Weise verklebt werden.The connection of the wooden parts is done by the glue layers either on the wooden parts to be connected or on the elastic layer can be applied on both sides and are then glued in a manner known per se.

Ein weiterer Gegenstand der Erfindung ist eine Holzkonstruktion, bestehend aus Rahmen, Beplankung und Verbindungsschicht, die dadurch gekennzeichnet ist, daß die Verbindungsschicht aus zwei Lagen Leim und einer dazwischen befindlichen Lage aus elasti­ schem Material besteht. Der Rahmen kann in Abhängigkeit seiner Größe zusätzliche Verstrebungen, z. B. waagrecht, senkrecht oder diagonal, aufweisen. Die Beplankung kann aus einer Platte oder aus einer Anzahl von Profilbrettern bestehen. Als Platte können die auf diesem Gebiet üblichen Platten, wie Sperrholzplatten, Verbundplatten oder Faserplatten, verwendet werden. Als Profil­ bretter werden bevorzugt Nut- und Federbretter eingesetzt.Another object of the invention is a wooden structure, consisting of frame, planking and connection layer, the characterized in that the tie layer consists of two Layers of glue and a layer of elasti in between chemical material. The frame can vary depending on its Size additional struts, e.g. B. horizontal, vertical or diagonally. The planking can be made from a panel or consist of a number of profiled boards. Can as a plate the panels common in this field, such as plywood panels, Composite panels or fiberboard can be used. As a profile boards are preferably tongue and groove boards used.

Die dreilagige Verbindungsschicht besteht aus zwei Leimschichten und einer dazwischenliegenden Schicht aus elastischem Material. Das elastische Material ist bevorzugt ein Schaumstoff, der besonders bevorzugt geschlossenzellig ist.The three-layer connection layer consists of two layers of glue and an intermediate layer of elastic material. The elastic material is preferably a foam that closed cell is particularly preferred.

Die Holzkonstruktion kann aus einem Rahmen mit einseitiger oder zweiseitiger Beplankung bestehen. Insbesondere ist die erfin­ dungsgemäße Holzkonstruktion eine Tür, ein Tor oder ein Paneel.The wooden structure can consist of a frame with one-sided or double-sided planking exist. In particular, it is invented  wooden structure according to the invention, a door, a gate or a panel.

Die nach dem erfindungsgemäßen Verfahren erhältlichen Holzkon­ struktionen verfügen über eine ausgezeichnete Stabilität gegen­ über Temperatur- und Feuchtigkeitseinflüssen und haben gleich­ zeitig eine gute Formstabilität.The Holzkon obtainable by the process according to the invention structures have excellent stability against about temperature and humidity influences and have the same good dimensional stability at an early stage.
