2 AT 504 886 B12 AT 504 886 B1
Die Erfindung betrifft ein bandförmiges Vorspannelement nach dem Oberbegriff des Anspruches 1 und hat zur Aufgabe, ein besonders einfaches Vorspannelement herzustellen.The invention relates to a band-shaped biasing member according to the preamble of claim 1 and has for its object to produce a particularly simple biasing element.
Durch die EP 777 020 B1 ist ein Vorspannelement bekannt geworden, bei welchem Monolitzen dicht Mann an Mann nebeneinander liegen.From EP 777 020 B1, a biasing element has become known, in which monostrands lie close together, one at a man next to the other.
Durch die EP 896 107 ist ein bandförmiges Vorspannelement bekannt geworden, welches aus mehreren, parallel zueinander verlaufenden Spanngliedern besteht, welche von einer gemeinsamen, vorzugsweise Kunststoff-bestehenden, Schutzhülle umschlossen sind, wobei sich die Spannglieder gegenseitig berühren. Die Schutzhülle ist außen und innen eben ausgeführt, wobei die einander gegenüberliegenden Zettel zweier einander sich berührenden Vorspannelemente mit Korrosionsschutzfett ausgefüllt sind.By EP 896 107 a band-shaped biasing element has become known, which consists of a plurality of mutually parallel tendons, which are surrounded by a common, preferably plastic-existing, protective cover, wherein the tendons touching each other. The protective cover is designed to be flat on the outside and inside, wherein the opposing tabs of two mutually contacting biasing elements are filled with corrosion protection grease.
Aufgabe der Erfindung ist es, ein bandförmiges Vorspannelement zu kreieren, welches noch einfacher in der Herstellung ist. Diese Aufgabe wird durch die Maßnahme nach dem kennzeichnenden Teil des Anspruches 1 erfüllt.The object of the invention is to create a band-shaped biasing element, which is even easier to manufacture. This object is achieved by the measure according to the characterizing part of claim 1.
Durch die Maßnahme nach Anspruch 2 wird ein besonderes günstiges Herstellungsverfahren erzielt.By the measure according to claim 2, a special favorable manufacturing process is achieved.
Weitere Merkmale der Erfindung werden anhand der Zeichnung näher erläutert, in welcher mehrere Ausführungsbeispiele des erfindungsgemäßen bandförmigen Vorspannelementes im Querschnitt dargestellt sind. Darin zeigen: Fig. 1 eine erste Ausführungsform des Vorspannelementes; Fig. 2 eine Ausführungsform der Schutzhülle; Fig. 3 einen Querschnitt der Schutzhülle in geöffnetem Zustand; Fig. 4 den Querschnitt einer zweiteiligen Schutzhülle; Fig. 5 eine weitere Ausführungsform des bandförmigen Vorspannelementes; Fig. 6 eine ähnliche Ausführungsform des Vorspannelementes; Fig. 7 eine weitere Form des Vorspannelements mit durchgehend äußerer Abflachung; Fig. 8 eine weitere Ausführungsform des erfindungsgemäßen bandförmigen Vorspannelementes, welche für Sonderfälle gedacht ist; die Fig. 9 und 10 Ausführungsformen, welche insbesondere für größere Spannkräfte gedacht sind; und Fig. 11 einen endseitigen Abschnitt der Schutzhülle.Further features of the invention will be explained in more detail with reference to the drawing, in which several embodiments of the band-shaped biasing element according to the invention are shown in cross section. 1 shows a first embodiment of the biasing element; Fig. 2 shows an embodiment of the protective cover; 3 shows a cross section of the protective cover in the opened state; 4 shows the cross section of a two-part protective cover; 5 shows a further embodiment of the band-shaped biasing element. Fig. 6 is a similar embodiment of the biasing member; 7 shows a further form of the biasing element with a continuous outer flattening. 8 shows a further embodiment of the tape-shaped biasing element according to the invention, which is intended for special cases. Figures 9 and 10 embodiments which are intended in particular for larger clamping forces. and Fig. 11 is an end portion of the protective cover.
Im vorliegenden Fall sind als Ausführungsbeispiele fünf als Zugglieder ausgebildete Litzen 1 vorgesehen, die nebeneinander Mann an Mann liegend angeordnet und von einer vorzugsweise aus Kunststoff bestehenden Schutzhülle 2 umschlossen sind. Die Litzen 1 sind blank, d.h. nicht wie Monolitzen von jeweils einem eigenen Kunststoffmantel umschlossen und von Fett oder einer dauerplastischen Masse umhüllt. Die Zwickel 4 dazwischen sind ebenfalls mit Fett oder der dauerplastischen Masse ausgefüllt.In the present case, five embodiments designed as tension members strands 1 are provided, which are juxtaposed man lying man and enclosed by a preferably made of plastic protective cover 2. The strands 1 are bare, i. not as each monolitzen surrounded by their own plastic sheath and wrapped in grease or a permanently plastic mass. The gussets 4 in between are also filled with fat or the permanently plastic mass.
Bei der Ausführungsform nach Fig. 1 folgt die Schutzhülle 2 der Form der Litzen 1 und bildet daher, wie der Figur zu entnehmen ist, eine Wellenform mit Mulden 6.In the embodiment of Fig. 1, the protective cover 2 follows the shape of the strands 1 and therefore forms, as the figure can be seen, a waveform with hollows. 6
Die Wandstärke der Schutzhülle 2 beträgt 1,3 bis 1,8 mm, vorzugsweise 1,5 mm.The wall thickness of the protective cover 2 is 1.3 to 1.8 mm, preferably 1.5 mm.
Die Fettschicht, welche die Litzen umschließt, kann eine Dicke von 0,3 bis 0,6 mm, vorzugsweise 0,5 mm, besitzen.The fat layer enclosing the strands may have a thickness of 0.3 to 0.6 mm, preferably 0.5 mm.
Die vorliegende Schutzhülle 2 ist auf das Band der nebeneinanderliegenden Litzen 1 aufextrudiert.The present protective cover 2 is extruded onto the band of the adjacent strands 1.
Bei der Ausführungsform des bandförmigen Vorspannelementes nach Fig. 2 ist die Schutzhülle 2 zangenartig und kann, wie in Fig. 3 dargestellt, geöffnet werden, um die Litzen 1 in die Mulden 6 einzulegen, worauf die Schutzhülle 2 geschlossen und endseitig mit einer Schweißnaht 3 versehen wird.In the embodiment of the band-shaped biasing member of FIG. 2, the protective cover 2 is like a pliers and can, as shown in Fig. 3, are opened to insert the strands 1 in the wells 6, whereupon the protective cover 2 closed and end provided with a weld 3 becomes.
