Description

Verfahren zum nachträglichen Verdübeln oder Verankern von durch Fugen oder Risse getrennten Betonfahrbahnplatten Zur Sicherung der planmäßigen Höhenlage von Betonfahrbahnplatten auf Straßen und Plätzen aller Art und zur Vermeidung von Stufen an den Fugen werden im allgemeinen Stahldübel eingebaut, die der Lastübertragung zwischen den einzelnen Betonplatten dienen. Diese Dübel müssen möglichst in der Mitte der Plattendicke, senkrecht zur Fuge, in hinreichender Anzahl und damit in verhältnismäßig kleinen Abständen voneinander eingebaut werden, damit sie durch örtliche Überbeanspruchung nicht aus dem Beton ausbrechen bzw. in diesem Risse verursachen.Process for subsequent dowelling or anchoring through joints or cracks separate concrete roadway slabs To secure the planned altitude of concrete slabs on streets and squares of all kinds and to avoid Steps at the joints are generally built in steel dowels to transfer the load serve between the individual concrete slabs. These dowels must be in the Middle of the board thickness, perpendicular to the joint, in sufficient number and thus in relatively small distances from each other to allow them to pass through Do not break local overstressing out of the concrete or cause cracks in it.

Bei vielen Betonfahrbahnplatten auf Straßen und Plätzen aller Art wurde jedoch aus verschiedenen Gründen von einer solchen Verdübelung der Fahrbahnplatten abgesehen, so daß sich im Laufe der Zeit infolge der Verkehrsbelastungen und durch Veränderungen im Untergrund Stufen an den Fugen gebildet haben. Das gleiche geschieht auch an Rissen in den Fahrbahnplatten, wenn diese keine Stahleinlagen haben. Zur Einregulierung solchermaßen verlagerter Betonplatten oder Betonplattenteile in die planmäßige Höhenlage gibt es verschiedene Verfahren. Dagegen fehlt es an einem möglichst einfachen, technisch zuverlässigen und wirtschaftlichen Verfahren, die einregulierten Platten oder Plattenteile durch Verdübelung oder Verankerung an den Fugen oder Rissen nachträglich in ihrer Höhenlage zu sichern. Nach der Erfindung wird eine solche nachträgliche Verdübelung oder Verankerung dadurch bewirkt, daß mittels z. B. einer rotierenden Karborundumscheibe in angemessenen Abständen (z. B. 40 bis 70 cm) in die miteinander zu verdübelnden oder zu verankernden Betonplatten oder Betonplattenteile beiderseits der Fuge oder des Risses und senkrecht zu diesen geradlinige Schlitze eingeschnitten werden. Diese Schlitze reichen ? bis 4 cm unter die Plattendickenmitte und erstrecken sich beiderseits der zu verdübelnden Fugen oder Risse auf die gleiche Länge. In die unteren Teile der Schlitze werden Formstahlstäbe eingelegt, worauf dann die Schlitze mit Beton verschlossen werden.With many concrete pavement slabs on streets and squares of all kinds However, for various reasons, such anchoring of the pavement slabs was avoided apart, so that over time as a result of traffic loads and by Changes in the subsurface have formed steps at the joints. The same thing happens also on cracks in the pavement slabs if they do not have steel inserts. To the Adjustment of such relocated concrete slabs or concrete slab parts in the There are various procedures for planned altitude. On the other hand, there is a lack of one as possible simple, technically reliable and economical procedures that adjusted Panels or panel parts by dowelling or anchoring at the joints or cracks to be subsequently secured in their altitude. According to the invention, such subsequent dowelling or anchoring caused by the fact that by means of z. B. one rotating carborundum disc at appropriate intervals (e.g. 40 to 70 cm) in the concrete slabs or concrete slab parts to be dowelled or anchored together on both sides of the joint or crack and perpendicular to these straight slots be cut. Are these slots enough? up to 4 cm below the center of the panel thickness and extend to the same on both sides of the joints or cracks to be dowelled Length. Shape steel bars are inserted into the lower parts of the slots, whereupon then the slots are sealed with concrete.

Die Schlitze werden zweckmäßig wechselweise unter einem Winkel von 70 bis 80° zur Fahrbahnoberfläche geneigt eingeschnitten. Wenn es sich um eine nachträgliche Verdübelung handelt, werden die Stahlstäbe je zur Hälfte wechselseitig mit einem Bitumenanstrich und einer einen kleinen Spielraum lassenden Ansteckkapsel aus Pappe oder Blech versehen. Bei einer nachträglichen Verankerung erfahren die Stahlstäbe kein solche Vorbehandlung.The slots are expediently alternately at an angle of 70 to 80 ° inclined to the road surface. If it is an afterthought Dowelling is involved, the steel rods are each half alternately with a Bitumen paint and a cardboard capsule that leaves a little space or sheet metal. In the event of subsequent anchoring, the steel rods experience no such pre-treatment.

In der Zeichnung ist ein Ausführungsbeispiel einer nach dem Verfahren der Erfindung hergestellten Verdübelung von zwei Fahrbahnplatten dargestellt.In the drawing, one embodiment is one according to the method the invention produced anchoring of two road slabs shown.

Fig. 1 stellt einen Querschnitt dar, und Fig.2 ist ein Grundriß einer Betonfahrbahndecke. In die Betonfahrbahn sind unter einem Winkel von 70 bis 80° zur Fahrbahnoberfläche Schlitze 1 eingeschnitten. In diese Schlitze sind die Formstahlstäbe 4 eingelegt.Fig. 1 is a cross section, and Fig. 2 is a plan view of one Concrete pavement. In the concrete pavement are at an angle of 70 to 80 ° Slots 1 cut into the road surface. The shaped steel bars are in these slots 4 inserted.

Um ein Hochdrücken oder Aufwärtswandern der eingelegten Stahlstäbe 4 zu verhindern, sind jeweils zwei mit einer Klammer 5 aus Flachstahl gegenseitig verankert. Die Klammern 5 kommen dabei in die Fugen oder Risse zu liegen. Schließlich werden die Schlitze mit Beton satt ausgefüllt und die anfänglich offengelegten Fugen oder Risse mit Fugenvergußmasse geschlossen. Die Stahlklammern 5 können aus Ersparnisgründen nach Erhärtung der Schlitzfüllungen und vor Ausführung des Fugenvergusses entfernt werden.About a pushing up or moving upwards of the inserted steel rods 4 to prevent each other two with a clamp 5 made of flat steel anchored. The brackets 5 come to lie in the joints or cracks. In the end the slots are filled with concrete and the joints that are initially exposed or cracks closed with joint sealing compound. The steel brackets 5 can for reasons of economy Removed after the slot fillings have hardened and before the joint filling is carried out will.

Die Länge, Breite und Tiefe sowie die Abstände der Schlitze 1 richten sich ebenso wie die Länge und die Querschnitte der Stahlstäbe 4 nach den jeweils vorliegenden konstruktiven Gegebenheiten sowie baulichen und betrieblichen Erfordernissen.Align the length, width and depth as well as the spacing of the slots 1 as well as the length and the cross-sections of the steel rods 4 according to the respective existing structural conditions as well as structural and operational requirements.
