METHOD AND DEVICE FOR JOINING COMPONENTS BY MEANS OF TENSIONING BOLTS |
摘要 |
<p>A method for joining components using tensioning bolts, wherein the pressure is linearly increased over time when the tension bolt is hydraulically tensioned by means of a tensioning device. When a target value (Pmax) is reached, the volume is blocked so that no more hydraulic oil is supplied. The pressure decreases when the components show a setting behaviour during a holding time (tH). Pumping is resumed when a lower threshold value (PI) is reached, resulting in a pressure increase up to the target value (Pmax).</p> |
