Description

nach unten offen und können Hilfshalteelemente in Form von Ringen 67 aufnehmen, die in den Halteteilen 63 angeordnet und an deren Grund, beispielsweise durch Verschweißen, befestigt sind.open at the bottom and can accommodate auxiliary holding elements in the form of rings 67 that are in the holding parts 63 are arranged and attached to their base, for example by welding.

Beim Einsetzen in die Längsbohrungen 64 werden die Sicherungsglieder 65 durch die Ringe 67 hindurchgeführt, wodurch die Verankerung des Gummistreifens 61 an den beiden Halteteilen 63 gesichert wird.When inserted into the longitudinal bores 64, the securing members 65 are passed through the rings 67, whereby the anchoring of the rubber strip 61 on the two holding parts 63 is secured will.

Die Halteteile 63 werden vorher an den Stahlbeton-Randteilen 69 mittels geteilter Anker 68 befestigt. Die Anker 68 sind mit der Unterseite jedes Halteventils 63 verschweißt und in die Stahlbeton-Randteile 69 eingebettet.The holding parts 63 are previously attached to the reinforced concrete edge parts 69 by means of split anchors 68. The anchors 68 are welded to the underside of each retaining valve 63 and into the reinforced concrete edge portions 69 embedded.

Wenn, wie in F i g. 1 gezeigt, die Stahlteile 71, 71' der Abschnitte 21', 22' ebene Oberseiten aufweisen, werden die vorgefertigten Stahlbeton-Randteile 69 mit den an ihnen befestigten Halteteilen 63 lösbar mittels Bolzen 70 an den Oberseiten der Abschnitte 21', 22' so befestigt, daß die Stahlbeton-Randteile 69 auf den Oberseiten der Stahlteile 71, 71' aufruhen.If, as in FIG. 1 shown, the steel parts 71, 71 'of the sections 21', 22 'have flat upper sides, the prefabricated reinforced concrete edge parts 69 with the holding parts 63 attached to them are detachable fastened by means of bolts 70 to the upper sides of the sections 21 ', 22' in such a way that the reinforced concrete edge parts 69 rest on the tops of the steel parts 71, 71 '.

Hierdurch wird der Zusammenbau und das Einsetzen der Fugeneinlage 60 wesentlich erleichtert, da es nicht notwendig ist, Zement, Mörtel od. dgl. bei der Herstellung der Verbindung zu verwenden. Die Fugeneinlage 60, die Halteteile 63 und die Stahlbeton-Randteile 69 werden in einfacher Weise dadurch befestigt, daß in die untere Schicht reichende Bolzen 70 durch die Stahlbeton-Randteile 69 geführt und auf diesen befindliche Muttern festgezogen werden.This makes the assembly and the insertion of the joint insert 60 much easier, since it it is not necessary to use cement, mortar or the like when making the connection. The joint insert 60, the holding parts 63 and the reinforced concrete edge parts 69 are fastened in a simple manner by that in the lower layer reaching bolts 70 passed through the reinforced concrete edge parts 69 and on these nuts are tightened.

ίο Eine Fahrbahndecke wird in an sich bekannter Weise nach dem Einbau der Fugeneinlage 60 dadurch hergestellt, daß die Zwischenschicht 25 a auf die untere Schicht aufgelegt und dann die Deckschicht 25 bündig mit der Oberseite des Gummistreifens 61 aufgebracht wird.ίο A road surface becomes more familiar in itself Way after the installation of the joint insert 60 produced in that the intermediate layer 25 a the lower layer is placed and then the top layer 25 is flush with the top of the rubber strip 61 is applied.

Zum Ausbauen der Fugeneinlage 60 werden die Sicherungsglieder 65 aus den Längsbohrungen 64 entfernt und der Streifen 61 wird dadurch abgenommen, daß die Wülste 62, die sich dann frei verformenTo remove the joint insert 60, the securing members 65 are removed from the longitudinal bores 64 removed and the strip 61 is removed in that the beads 62, which then deform freely

ao können, aus den Halteteilen 63 herausgezogen werden. ao can be pulled out of the holding parts 63.
