Abstract
Description
Die Erfindung betrifft ein Bindeelement zur Uebertragung von Spannkraft von einer Spannmutter auf ein Bauelement oder mehrere nebeneinander gelegene Bauelemente.The invention relates to a binding element for the transmission of clamping force from a clamping nut to one component or to several components lying next to one another.
Im Hochbau, insbesondere beim Erstellen vom Schalungen für Wände, Säulen und Decken werden solche Bindeelemente geläufig verwendet etwa beim « Binden von aus Kanthölzern oder aus vielfach gelochten Stahlprofilstäben bestehenden Bauelementen. Als Spannkraft übertragende Bindelemente werden hierbei rechteckige, möglichst steife Platten verwendet, die eine zentrale Bohrung für den Durchlass des die Spannmutter tragenden Spannstabes haben. Bei den Platten handelt es sich dabei entweder um flache Stahlplatten, oder um solche in denen zur Erhöhung ihrer Steifigkeit Wölbungen gepresst sind, oder um Stahlgussplatten, die einseitig verrippt sind.In building construction, particularly when creating formwork for walls, pillars and ceilings, such binding elements are commonly used, for example, when «binding elements made of squared timber or multi-perforated steel profile bars. Rectangular plates which are as stiff as possible and which have a central bore for the passage of the tensioning rod carrying the tensioning nut are used as binding elements which transmit tensioning force. The plates are either flat steel plates, or those in which bulges are pressed to increase their rigidity, or cast steel plates that are ribbed on one side.
Der Erfindung lag die Aufgabe zugrunde, ein Bindeelement zu schaffen, das bei gleicher Länge wie diese bekannten plattenartigen Bindeelemente imstande ist, eine mindestens gleich grosse Spannkraft zu übertragen, aber ein bedeutend geringeres Gewicht aufweist und bei rationeller Herstellung auch billiger ist zumindest als die Stahlplatten und insbesondere als die verrippten Stahlgussplatten.The invention had for its object to provide a binding element which is able to transmit at least the same size clamping force at the same length as these known plate-like binding elements, but has a significantly lower weight and is more economical at least as the steel plates and especially as the ribbed cast steel plates.
Im Sinne der Lösung dieser Aufgabe wird ein Bindeelement der eingangs erwähnten Gattung vorgeschlagen, das gemäss dem kennzeichnenden Teil des Anspruches 1 ausgebildet ist.In order to achieve this object, a binding element of the type mentioned at the outset is proposed, which is designed in accordance with the characterizing part of
Es leuchtet ein, dass bei solcher Ausbildung die Spannkraftausbreitung von der kürzeren der beiden Querwände (auf welcher die Spannmutter aufliegen wird) auf die längere Querwand (die an dem oder den zu spannenden Bauelement(en) anliegen wird) durch die trapezförmigen Seitenwände übernommen wird, die zugleich versteifend wirken ; deshalb kann für alle Wände eine für die Gewichts- und Materialersparnis massgebliche Wandstärkenverminderung vorgesehen werden. Es leuchtet auch ein, dass eine Vielzahl der Bindeelemente im Zuge einer recht wirtschaftlichen Fertigung als Sägeabschnitte eines Vierkantrohres erhalten werden kann, wobei die Löcher vor oder nach dem Sägen eingestanzt werden können.It is obvious that with such a configuration the spreading of the clamping force from the shorter of the two transverse walls (on which the clamping nut will rest) to the longer transverse wall (which will rest on the component (s) to be clamped) is taken over by the trapezoidal side walls, which also have a stiffening effect; therefore a significant reduction in wall thickness for weight and material savings can be provided for all walls. It also makes sense that a large number of the binding elements can be obtained as saw sections of a square tube in the course of fairly economical production, the holes being able to be punched in before or after sawing.
Die Erfindung wird nachfolgend anhand beiliegender Zeichnung beispielsweise erläutert. Es zeigen :
Figur 1 einen Aufriss einer Ausführungsform des erfindungsgemässen Bindegliedes,Figur 2 einen Schnitt nach der Linie 11-II der Fig. 1,- die
Figur 3 und dieFigur 4 Ansichten, die eine erste bzw. eine zweite Verwendungsmöglichkeit des in den Fig. 1 und 2 dargestellten Bindegliedes veranschaulichen.
- FIG. 1 shows an elevation of an embodiment of the connecting link according to the invention,
- 2 shows a section along the line 11-II of FIG. 1,
- FIG. 3 and FIG. 4 are views which illustrate a first and a second possible use of the link shown in FIGS. 1 and 2.
Das in der Zeichnung mit B bezeichnete Bindeglied besteht aus einem Abschnitt eines Vierkantstahlrohres (mit Rechteck-Querschnittsform), das in Ansicht auf eine der schmäleren Längsseiten bzw. Wände 1, 2 die Form eines gleichschenkeligen Trapezes hat, so dass von den beiden zu diesen Längsseiten bzw. Wänden winkelrecht stehenden, breiteren Querwänden 3, 4 die eine 3 etwa eine Länge hat, die ungefähr das Dreifache derjenigen der anderen 4 beträgt. Diese Querwände 3, 4 haben ein zentrales Rundloch 5, 6 für den Durchlass eines Spannstabes. Die über die kürzere 3 der beiden Querwände überragenden Endpartien der längeren 4 dieser Querwände (die also ungefähr gleich lang sind wie diese kürzere Querwand 4) sind in längsassymmetrischer Anordnung mit einem Rundloch 7 bzw. 8 und mit einem weiteren, längsverlaufenden Langloch 9 bzw. 10 versehen.The link designated B in the drawing consists of a section of a square steel tube (with a rectangular cross-sectional shape), which in view of one of the narrower long sides or
In den Fig. 3 und 4, die beispielsweise zwei Verwendungsbeispiele des eben beschriebenen Bindeelementes B veranschaulichen, sind mit 11 vielfach gelochte Stahlprofilträger von der im DE-Gebrauchsmuster 7 709 554 offenbarten Bauart, mit 12 ein Spannstab mit aufgewalzter Gewinderippe und mit 13 eine auf dem Spannstab verschraubbare Flügelmutter bezeichnet. Im Verwendungsbeispiel nach Fig: 3 ist vorausgesetzt, dass Spannkraft vom Spannstab 12 über die Flügelmutter 13 auf das einzige, dort vorhandene Bauelement (bei dem es sich z. B. um einen Kantholzstab anstelle des Stahlprofilstabes handeln könnte) zu übertragen ist. Das Bindeglied B verläuft mit seiner Längsrichtung parallel zu derjenigen des Stabes 11 und liegt mit seiner ganzen längeren Querwand 3 auf diesem Stab auf.3 and 4, which illustrate, for example, two examples of the use of the binding element B just described, are with 11 perforated steel profile beams of the type disclosed in
Im Verwendungsbeispiel nach Fig. 4 überträgt das Bindeglied B die Spannkraft auf die drei nebeneinander angeordneten Stahlprofilstäbe 11, zu denen es in diesem Fall quer angeordnet ist.In the example of use according to FIG. 4, the link B transmits the clamping force to the three
Man könnte sich vorstellen, dass der mittlere der drei Stahlprofilstäbe 11 weggelassen und die beiden anderen näher bei einander angeordnet wären.One could imagine that the middle one of the three
In analogen Verwendungen könnten sich zwei Spannstäbe wie 12 durch die Langlöcher 9, 10 des Bindegliedes erstrecken, wobei dann anstelle von Flügelmuttern wie 13 gewöhnliche Muttern (zusammen mit Unterlagscheiben) Verwendung finden würden. Gerade in solchen Fällen ergibt die assymmetrische Anordnung der Löcher 7-10 mehr Freiheit hinsichtlich des gegenseitigen Abstandes der Stahlprofilstäbe 11 bzw. der Spannstäbe 12.In analog uses, two tie rods such as 12 could extend through the
Wie in Fig. 4 angedeutet ist, können die Löcher 7, 8 beispielsweise Verwendung finden zum Durchlass von Schrauben 14, die zusammen mit Muttern 15 zur lösbaren Befestigung des Bindeelementes B an einem der Profilstäbe 11 dienen.As indicated in FIG. 4, the
