摘要

Device for joining two pile sections, preferably reinforced concrete, comprising two substantially cap-shaped members adapted to encircle, respectively, the adjacent ends of the two pile sections to be joined, said cap-shaped members having means for which can be joined by mutual rotation, characterized in that each of said cap-shaped members has an end wall arranged so as to face the corresponding end wall of the other cap-shaped member, having at least one of said cap-shaped members on its end wall a central clamping head having a radial extension smaller than any of the end walls and having a bearing surface disposed substantially in the radial plane and adapted to rest on a corresponding bearing surface in the end wall of the other member in the form of a cap, a coupling sleeve located between said end walls and peripherally surrounding said clamping head and is connected to the other of said end walls, application surfaces on said clamping head adapted to cooperate with corresponding application surfaces on said coupling sleeve so as to These support surfaces are forced against each other to form a butt joint with the cap-shaped members rigidly connected to each other by rotation of said clamping head and said coupling sleeve during a portion of a relative revolution about the axis of said head. sleeve.
