CYLINDRICAL PILE AND CYLINDRICAL PILE EXTENSION ELEMENT
Cylindrical pile element (10) with a longitudinal axis (V), for use as a reinforcing or supporting construction element, having a cross-sectional cylinder diameter of at least 70 mm, being arranged to be lengthwise extendable using a cylindrical sleeve element (20), using a male pile element thread comprised in a pin end (11) of the said pile element and arranged to engage with a corresponding female sleeve element thread comprised in the said sleeve element at a respective box end (21) of the sleeve element, which pile element thread is generally tapered. The invention is characterised in that the side flank of the pile element thread facing towards the pin end is inclined between 15° and 25° in relation to a plane perpendicular to the longitudinal axis, and in that the side flank facing away from the pin end is inclined between 6° and 8° in relation to said plane.
