Es ist aber auch möglich, in der in F i g. 2 gezeigten Weise das Element 13' bzw. den Abstandhalterzapfen 14' mit einem Wulst 18' zu versehen, der zwei Kegelflächen 19 und 20 aufweist und der nach außen über die z. B. zylindrische Mantelfläche des Verbindungselements 13' herausragt. Wenn zwischen dem das Verbindungselement 13' und dem dieses umgebenden Beton ein Spalt entstanden sein sollte, so wird jeweils eine der beiden Flächen 19 oder 20 bei Volumenänderungen infolge von Temperaturunterschieden oder dergleichen die gewünschte Spaltabdichtung herbeiführen.But it is also possible in the in F i g. 2 shown Way to provide the element 13 'or the spacer pin 14' with a bead 18 ', the two Has conical surfaces 19 and 20 and the outward via the z. B. cylindrical outer surface of the connecting element 13 'protrudes. If between the connecting element 13 'and that surrounding it If a gap should have arisen in concrete, one of the two surfaces 19 or 20 is shown in each case Volume changes as a result of temperature differences or the like the desired gap sealing bring about.
Bei dem Element nach F i g. 3 ist durch eine ausgerundete Rille dieselbe Wirkung zu erzielen.In the element according to FIG. 3 the same effect can be achieved with a rounded groove.
Selbstverständlich ist es auch möglich, in oder an dem Verbindungselement bzw. Abstandhalterzapfen mehrere Rillen bzw. Wülste anzuordnen, wobei dann die Oberfläche des Abstandhalterzapfens vorzugsweise ein sägeförmiges Profil aufweist; dadurch werden dann die Dichtflächen entsprechend vermehrt.Of course, it is also possible in or on the connecting element or spacer pin to arrange several grooves or beads, in which case the surface of the spacer pin is preferred has a saw-shaped profile; this then increases the sealing surfaces accordingly.
Die erfindungsgemäße Ausbildung der Abstandhalterzapfen der Verbindungselemente ist vor allem dann von Bedeutung, wenn das Verbindungselement aus Kunststoff besteht, der bei Temperaturschwankungen eine dreimal so große Volumenänderung erfährt wie der Beton. Es ist dann die Gefahr der Bildung feiner Spalte zwischen den Verbindungselementen und dem diese umgebenden Beton besonders groß.The inventive design of the spacer pins of the connecting elements is above all then of importance if the connecting element is made of plastic, the temperature fluctuations undergoes a volume change three times as large as the concrete. It is then the risk of Formation of fine gaps between the connecting elements and the concrete surrounding them in particular great.
