Das Hauptpatent'-betriftt ein Verfahren zum nachträglichen Verdübeln oder Verankern von durch Fugen oder Risse getrennten Betonfahrbahnplatten, bei dem mittels einer rotierenden Betoiischleifscheibe in die miteinander zu verdübelnden oder zu verankernden Betonplatten oder Betonplattenteile beiderseits der Fuge oder des Risses und senkrecht zu diesen geradlinige Schlitze geschnitten weiden, die nach Einlegen von "Fonnstahlstäben mit Beton verschlossen werden. Die eine rechteckige Querschnittsform auf- jo weisenden Schlitze sind zweckmäßig unter, einem Winkel von 70 bis 80° zur Fahrbahnoberfläche eingeschnitten. The main patent concerns a process for subsequent Dowelling or anchoring concrete deck slabs separated by joints or cracks, by means of a rotating concrete grinding wheel into the concrete slabs or concrete slab parts to be dowelled or anchored on both sides the joint or crack and perpendicular to them straight slits are cut, which are sealed with concrete after inserting "steel rods" will. Which has a rectangular cross-sectional shape Pointing slots are expediently cut at an angle of 70 to 80 ° to the road surface. Das Verfahren nach dem Hauptpatent wird erfin- ; dnngsgemäß dadurch verbessert, daß die Schlitze »5 durch zweimaliges Einschneiden an derselben Stelle einen nach unten erweiterten trapezförmigen Querschnitt erhalten. Die Schlitzbreite nimmt also von der Oberfläche .der Betonfahrbahn zur Mitte der Betonplatte ständig zu. Die trapezförmige SchÜtzausbildung so ergibt eine besonders gute Verdübelung der durch Fugen oder Risse voneinander getrennten Fahrbahnplatten. The method according to the main patent is invented ; Improved longitudinally in that the slots »5 are given a downwardly widened trapezoidal cross-section by cutting twice at the same point. The width of the slot therefore increases steadily from the surface of the concrete roadway to the center of the concrete slab. The trapezoidal SchÜtzausbildung thus results in a particularly good dowelling of the carriageway slabs, which are separated from one another by joints or cracks. Der zwischen den beiden Schnitten zur Herstellung des Schlitzes sich ergebende Betonsteg läßt sich leicht herausbrechen, sofern er nicht schon während des zweiten Schnittes von selbst herausbricht.The concrete web resulting between the two cuts to produce the slot can be easily break out, unless it breaks out by itself during the second cut.
