Figur 3 einen Längsschnitt durch zwei aneinander gefügte Bauelemente mit den Verbindungsgliedern und einer Spannvorrichtung entlang der Linie III-III der Fig.4 und FIG. 3 shows a longitudinal section through two components joined together with the connecting links and a tensioning device along the line III-III in FIGS
Figur 4 einen Querschnitt durch die Bauelemente und die Verbindungsglieder. FIG. 4 shows a cross section through the components and the connecting links.
"Die Fig. 1 und 2 zeigen je einen Teil von zwei aneinander-zufügenden Bauelementen 1 und 2, die mit einem Abstand A voneinander entfernt sind, im Schnitt. In den Bauelementen 1 und 2 sind Verbindungsglieder 3 fest verankert. Die Verbindungsglieder 3 sind an ihren freien Enden mit Bohrungen 4 versehen. Die Bohrachsen, aller auf einem Bauelement angebrachten Verbindungsglieder 3, liegen möglichst in einer Geraden. Die Bohrungen der Verbindungsglieder 3 vom Bauelement 1 und die Bohrungen der Verbindungsglieder vom Bauelement 2 überschneiden sich teilweise, so daß eine DurchgangsÖffnung 5» von der Form zweier aneinandergefügten Kreisabschnitte, besteht. In dieser Öffnung 5 befindet sich ein Stab 6, an dem in gleichen Abständen wie die wechselseitig paarweise in den Bauelementen angeordneten Verbindungsglieder 3 keilförmige Ansätze (Fig.3) angebracht sind. Der Stab durchdringt alle Bohrungen der Verbindungsglieder und reicht mit seinen Enden über die äußersten Verbindungsglieder hinaus.1 and 2 each show a part of two components 1 and 2 to be joined together, which are spaced apart from each other by a distance A. Connecting links 3 are firmly anchored in components 1 and 2. The connecting links 3 are on their free ends are provided with bores 4. The drilling axes of all connecting links 3 attached to a building element are as far as possible in a straight line In this opening 5 there is a rod 6 to which wedge-shaped attachments (Fig. 3) are attached at the same intervals as the connecting links 3 arranged alternately in pairs in the structural elements. The rod penetrates all the bores of the connecting links and extends with its ends beyond the outermost connecting links.

Mit "D ist der Abstand der Bohrwände 4» welche gleich dem Abstand der Bohrachsen aller auf einem Bauelement 1 zu der Bohrachse aller auf dem Bauelement 2 befestigten Verbindungsglieder ist, bezeichnet und ist größer als der Abstand A."D" is the distance between the drilling walls 4 »which is equal to the distance between the drilling axes of all on a component 1 and the drilling axis of all connecting links attached to the structural element 2, and is greater than the distance A.
Wird der Stab 90° um seine Längsachse gedreht, dann erhält man den Zustand, wie er in den Pig. 3 und 4 und mittels einer Zugvorrichtung, bestehend aus einem auf dem Stab 6 aufgesetzten Gewindebolzen 8, einer Schraubenmutter 9» einer Druckverteilscheibe 10 und einen Abstützkörper 11 in der Pfeilrichtung 12 nach oben gezogen, dargestellt ist. Durch die VierteIsdrehung und Zu0- nach oben ist die gemeinsame Bohrachse aller Verbindungsglieder 3 des Bauelementes 1 der gemeinsamen Bohrachse aller Verbindungsglieder 3 des Bauelementes 2 genähert worden, wobei die beiden Bauelemente durch die Formteile 8 und 9 des Bauelementes 1 gegeneinander abgestützt sind. Diese vorstehenden Teile decken gleichzeitig die Verbindungseinrichtung ab, so daß letztere, von den Hauptseiten der Bauelemente aus gesehen, unsichtbar sind.If the rod is rotated 90 ° around its longitudinal axis, then one obtains the state as it is in the pig. 3 and 4 and by means of a pulling device consisting of a threaded bolt 8 placed on the rod 6, a screw nut 9 »a pressure distribution disk 10 and a support body 11 pulled up in the direction of arrow 12. Through the fourth rotation and to 0 - up, the common drilling axis of all connecting links 3 of component 1 has been brought closer to the common drilling axis of all connecting links 3 of component 2, the two components being supported against one another by molded parts 8 and 9 of component 1. These protruding parts simultaneously cover the connecting device, so that the latter are invisible as seen from the main sides of the structural elements.
Die Abmessungen des Stabes 6 und der keilförmigen Ansätze 7 sind derart gewählt, daß der Stab in der in Fig. 2 gezeichneten Stellung mit seinen Ansätzen durch die durch zwei Kreisbogen begrenzte öffnung 5 hindurchgesteckt werden kann. Die Drehung des Stabes um 90° wird durchgeführt, wenn sich die keilartigen Ansätze gerade unterhalb der zugehörigen Verbindungeglieder befinden. Beim Hochziehen des Stabes mittels der Zugvorrichtung werdenThe dimensions of the rod 6 and the wedge-shaped projections 7 are selected such that the rod is in the position shown in FIG can be inserted with its approaches through the opening 5 delimited by two circular arcs. The rotation of the rod 90 ° is performed when the wedge-like lugs are just below the associated connecting links. When you pull up the rod by means of the pulling device

dann die dem Stab am nächsten liegenden Innenflächen der Bohrungen 4- einerseits am Stab selbst und andererseits an der schrägen Fläche der Ansätze anliegen und durch die Keilwirkung auseinander gedruckt, was bewirkt, daß die Sauelemente 1 und 2 zueinander gezogen werden und zwar umso fester, je stärker die Schraubmutter 9 abgezogen wird.then the inner surfaces of the holes closest to the rod 4- on the one hand on the rod itself and on the other hand on the sloping one The surface of the lugs and pressed apart by the wedge effect, which causes the sowing elements 1 and 2 to each other be pulled and the tighter the stronger the nut 9 is deducted.
Vorzugsweise sind die Abstände der keilartigen Ansätze 7 verstellbar, um Abstandungenauigkeiten der Verbindungsglieder ausgleichen zu können. Diese Verstellbarkeit kann dadurch erfolgen, daß die Länge des Stabes zwischen zwei Ansätzen einstellbar ist oder daß die Ansätze auf dem Suab verstellbar befestigt sind. The distances between the wedge-like extensions 7 are preferably adjustable in order to be able to compensate for inaccuracies in the spacing of the connecting links. This adjustability can take place in that the length of the rod is adjustable between two approaches or that the approaches are attached to the Suab in an adjustable manner.
Falls sich die Verbindung mit der Zeit infolge Ermüdungserscheinungen der dauernd auf Zug oder Druck beanspruchten Teile löst, so besteht die Möglichkeit, die Schraubmutter weiter anzuziehen, wodurch die Verbindung zwischen den Bauelementen wieder gefestigt wird. If the compound dissolves with time due to fatigue of the permanently stressed by train or pressure parts, so it is possible to further tighten the screw nut, is strengthened again whereby the connection between the components.
Anstelle des Zugmittels kann auf der gegenüberliegenden Seite auch ein Druckmittel auf den Stab einwirken. Wichtig ist nur, daß die dem Stab erteilte Bewegungsrichtung mit der Richtung des Pfeiles 12 übereinstimmt.Instead of the pulling means, a pressure means can also act on the rod on the opposite side. The only important thing is that the direction of movement given to the rod coincides with the direction of arrow 12.

Die Formteile 8 und 9 können mit beliebigem Anteil, auf den Bauelementen angebracht werden, oder aus besonderen Teilen bestehen. Die Trennfuge, »velohe zwischen den beiden zusammengefügten Bauelementen entsteht, kann eine Gerade sein, oder eine beliebige zweckmäßige Form aufweisen, z.B. zwei einen V/ink el bildende strahlen. Auf diese Weise wird eine zweckmässige Führung in die Sollage der beiden Bauelemente zueinander erreicht.The molded parts 8 and 9 can, with any proportion, on the components be attached, or consist of special parts. The parting line, »almost between the two assembled structural elements arises, can be a straight line, or have any suitable shape, e.g. two forming a square shine. In this way, an appropriate leadership in the Target position of the two components to each other reached.
