Abstract

The invention concerns shaped sections (11) with an open, channel-like groove (13) running along, or parallel to, the longitudinal axis of the shaped sections. The ends of the groove (13) are connected by a PVC cover plate (12) whose shape matches that of the grooves (13), which overlaps the ends of the grooves (13) and which is bonded to the outside or inside of the grooves (13). The clip comprises an upper part resistant to the adhesive and a lower part also resistant to the adhesive. The upper part has a U-shaped recess (1) whose shape matches that of the external surface of the groove (13) and rests against it to form a seal, while the lower part has an external surface (7) whose shape matches that of inside surface of the groove (13) and rest against it to form a seal. The length of the upper and lower parts of the clip is essentially the same as, or greater than, the length of normally used cover plates (12). The lower part is mounted on a plate (9) which is also resistant to adhesive. The clip ensures a durable bond even between long sections.

Description

'Klemmvorrichtung zum klebenden Verbinden von Profilen aus PVC" 'Clamping device for the adhesive connection of profiles made of PVC "
Die Erfindung bezieht sich auf eine Vorrichtung, die zum klebenden Verbin¬ den von langgestreckten Profilen aus PVC an ihren Querseiten einsetzbar ist. Die Profile weisen jeweils eine parallel zu oder in der Längsachse der Profile verlaufende, offene rinnenartige Nut auf. Zum Verbinden der Profile werden die Enden der Nuten mittels einer Form der Nut angepaßten, die Enden überlappenden und auf die Außen- oder Innenseite der Nuten auf¬ geklebten Lasche aus PVC verbunden.The invention relates to a device which can be used for the adhesive connection of elongated profiles made of PVC on their transverse sides. The profiles each have an open channel-like groove running parallel to or in the longitudinal axis of the profiles. To connect the profiles, the ends of the grooves are matched by means of a shape of the groove which overlaps the ends and is glued onto the outside or inside of the grooves and is glued from PVC.
Derartige miteinander verbundene Profile werden z.B. für Gärtnereien in Treibhäusern oder im Freiland eingesetzt und dienen als Auflagefläche für Pflanzenerde bzw. spezielles Pflanzensubstrat. Die Nut dient zum Abfluß von überschüssigem Flüssigdünner. Die auf dem Boden aufliegenden, oft über 80 m langen PVC-Profile werden üblicherweise jedes Jahr entfernt, der Un¬ tergrund wird neu bearbeitet, und neue Rinnen zur Aufnahme der Profilnuten werden gezogen. Auf den so vorbereiteten Untergrund werden die Profile wieder aufgelegt und mit neuem Pflanzensubstrat gefüllt.Such interconnected profiles are e.g. used for garden centers in greenhouses or in the field and serve as a support surface for plant soil or a special plant substrate. The groove is used to drain excess liquid thinner. The PVC profiles lying on the floor, often over 80 m long, are usually removed every year, the subsurface is reworked and new channels are drawn to accommodate the profile grooves. The profiles are put back on the prepared surface and filled with new plant substrate.
Beim Entfernen der alten, aus etwa 5 m langen Stücken geklebten Profile reißen die Klebestellen häufig auf, und eine kostspielige Reparatur oder gar Erneuerung des gesamten Profils ist notwendig.When the old profiles, which are glued from approximately 5 m long pieces, are removed, the adhesive points frequently tear open, and expensive repair or even renewal of the entire profile is necessary.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Hilfsvorrichtung be¬ reitzustellen, bei deren Verwendung eine dauerhaftere Verklebung der Pro¬ filstücke gewährleistet ist.The invention is therefore based on the object of providing an auxiliary device which, when used, ensures a more permanent bond of the profile pieces.
Erfindungsgemäß besteht diese Vorrichtung aus einem gegenüber dem Kleb¬ stoff beständigen Oberteil und einem ebenfalls klebstoffbeständigen Un¬ terteil. Das Oberteil weist eine U-förmige, der Außenfläche der Nut zum dichten Anliegen daran angepaßte Ausnehmung und das Unterteil eine der Innenfläche der Nut zum dichten Anliegen daran angepaßte Außenfläche auf. Die Länge von Ober- und Unterteil ist im wesentlichen gleich der Länge üblicher Laschen, die auf die Enden der Nuten geklebt werden, oder größer. Außerdem ist das Unterteil auf einer ebenfalls klebstoffbeständigen Platte angebracht.According to the invention, this device consists of an upper part which is resistant to the adhesive and a lower part which is also adhesive-resistant. The upper part has a U-shaped, the outer surface of the groove tight fit thereon recess and the lower part of the inner surface of the groove for tight fit thereon outer surface. The length of the upper and lower part is substantially equal to or greater than the length of conventional tabs that are glued to the ends of the grooves. In addition, the lower part is attached to an adhesive-resistant plate.
Wie der Erfinder festgestellt hat, liegt die Ursache in der geringen Sta¬ bilität der Klebeverbindung darin, daß die die Enden der Nuten überlap¬ pende Lasche während der Erhärtung des Klebstoffs nicht mit der gesamten Fläche an der Außen- bzw. Innenfläche der Nut anliegt und damit eine vollflächige Verklebung nicht gegeben ist. Wenn jedoch erfindungsgemäß die Lasche mittels des von oben und unten auf die Klebestelle gedrückten Ober¬ bzw. Unterteils an die Enden der Nuten gepreßt und mit der Klemmvorrich¬ tung in dieser Lage fixiert wird, erhält man eine vollflächige Verklebung mit einer sehr viel größeren Stabilität. Die auf diese Weise verklebten Profile lassen sich beim jährlichen Austausch ohne Beschädigung vom Un¬ tergrund entfernen und wieder auf den neu vorbereiteten Boden aufbringen. Obwohl der Klebevorgang, ein sogenanntes "Kaltverschweißen" mit lösungs- mittelhaltigem Spezial-PVC-Klebstoff, z.B. Tangit (Produkt der Fa. Henkel KGaA), kein Verpressen unter Druck erfordert, zeigte es sich im vorlie¬ genden Fall, daß das Einklemmen der Klebestelle, also eine Druckausübung, dennoch zu einem erheblich besseren Klebeergebnis führt.As the inventor has determined, the reason for the low stability of the adhesive connection lies in the fact that the tab overlapping the ends of the grooves does not lie with the entire surface against the outer or inner surface of the groove during the hardening of the adhesive and so that there is no full-surface gluing. However, according to the invention, if the flap is pressed onto the ends of the grooves by means of the upper or lower part pressed onto the adhesive point from above and below and fixed in this position with the clamping device, full-area gluing with much greater stability is obtained. The profiles glued in this way can be removed from the subsurface and replaced on the newly prepared floor during annual replacement. Although the gluing process, a so-called "cold welding" with solvent-containing special PVC glue, e.g. Tangit (product from Henkel KGaA), which does not require pressing under pressure, showed in the present case that the pinching of the adhesive point, that is to say pressure exerted, nevertheless leads to a considerably better adhesive result.
Zur leichteren Handhabung weist das Oberteil bevorzugt einen Handgriff, insbesondere in Form des Bügels auf.For easier handling, the upper part preferably has a handle, in particular in the form of the bracket.
Eine Vergrößerung der Biegesteifigkeit des Oberteils wird in einer weite¬ ren vorteilhaften Ausführungsform dadurch erreicht, daß das Oberteil im wesentlichen aus einem Stab mit rechteckiger Querschnittsfläche besteht, dessen eine Seite die der Außenfläche der Nut des Profils angepaßte Aus- nehmung aufweist.In a further advantageous embodiment, the bending stiffness of the upper part is increased in that the upper part essentially consists of a rod with a rectangular cross-sectional area, one side of which has the recess adapted to the outer surface of the groove of the profile.
Das nach dem Klebevorgang erforderliche Entfernen der Klemmvorrichtung wird erleichtert, wenn der an die Platte angrenzende Bereich des Unter¬ teils schmaler als der entsprechende Bereich der Nut des Profils ist. Überschüssiges, erhärtetes Klebstoffmaterial läßt sich von der Klemmvor¬ richtung problemlos entfernen, wenn die Oberflächen von Ober- und Unter¬ teil von glatter Beschaffenheit sind.The removal of the clamping device required after the gluing process is facilitated if the area of the lower part adjacent to the plate is narrower than the corresponding area of the groove of the profile. Excess, hardened adhesive material can be easily removed from the clamping device if the surfaces of the upper and lower part are smooth.
Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand von Zeich¬ nungen näher beschrieben. Es zeigenAn exemplary embodiment of the invention is described in more detail below with reference to drawings. Show it

Das aus HD-PE (High Density Polyethylen) bestehende Oberteil besteht im wesentlichen aus einem quaderfδrmigen Block mit einer U-förmigen, dem je¬ weiligen zu verklebenden Profil angepaßten Ausnehmung 1 (Figuren 1 und 2). Der quaderförmige Block 2 läuft nach oben in einen Handgriff 3 aus, der zur besseren Handhabung mit einem Schlitz 4 versehen ist. Die oberen Kan¬ ten 5 des quaderförmigen Blocks 2 wurden nicht in Anpassung an die Ausnehmung 1 abgeschrägt oder abgerundet, sondern bleiben bestehen, um während des Klemmvorgangs eine größere Biegefestigkeit der unteren Schen¬ kel 6 zu erreichen.The upper part made of HD-PE (High Density Polyethylene) essentially consists of a cuboid block with a U-shaped recess 1 (FIGS. 1 and 2) adapted to the profile to be glued. The cuboid block 2 runs upwards into a handle 3, which is provided with a slot 4 for better handling. The upper edges 5 of the cuboid block 2 were not bevelled or rounded to match the recess 1, but remain in place in order to achieve a greater bending strength of the lower legs 6 during the clamping process.
Das Unterteil weist in seinem oberen Bereich eine der Profilform angepaßte Außenfläche 7 auf und ist in seinem unteren Bereich 8 verjüngt und dort an einer Platte 9 befestigt.The lower part has an outer surface 7 adapted to the profile shape in its upper region and is tapered in its lower region 8 and fastened there to a plate 9.
Mit der erfindungemäßen Klemmvorrichtung läuft der Klebevorgang wie folgt ab. Das Unterteil wird mit der Platte 9 auf den Untergrund 10 gelegt und die zur verklebenden Enden der Profile 11 darauf angeordnet. Nach dem Auftragen des Klebstoffs auf die Enden der Profile 11 und gegebenenfalls auch auf die Klebelasche 12 sowie nach Einhalten einer eventuellen Warte¬ zeit wird die Lasche 12 auf die Anschlußstelle der Nut 13 der Profile 11 aufgebracht und mit dem Oberteil festgeklemmt. Nach dem Erhärten des Klebstoffs können Ober- und Unterteil wieder entfernt werden, und man er¬ hält eine Klebeverbindung wie in Figur 6 dargestellt. Die zusammengefügten Profile in Figur 6 müssen dann nur noch umgedreht werden, so daß die Nut in eine im Boden vorgesehene Rille einliegen kann. Das Profilsystem ist gebrauchsfertig und kann mit dem Pflanzensubstrat befüllt werden.With the clamping device according to the invention, the gluing process proceeds as follows. The lower part is placed with the plate 9 on the substrate 10 and the ends of the profiles 11 to be glued are arranged thereon. After this Applying the adhesive to the ends of the profiles 11 and, if appropriate, also to the adhesive tab 12 and after observing a possible waiting time, the tab 12 is applied to the connection point of the groove 13 of the profiles 11 and clamped to the upper part. After the adhesive has hardened, the upper and lower part can be removed again, and an adhesive connection is obtained as shown in FIG. 6. The assembled profiles in FIG. 6 then only have to be turned over so that the groove can lie in a groove provided in the base. The profile system is ready for use and can be filled with the plant substrate.
