Coupling system for concrete piles - uses clamping pins drivable into coupling holes in connecting parts

摘要

Each of the two circular identical coupling parts has holes (4) for the reinforcing iron and a central inspection hole (5). Diametrically opposed locking eyelets (6, 7) project above the flat surfaces of the disc-shaped part on its circumference. A pair of diametrically opposed depressions (10, 11) are arranged at the disc edge displaced by 90 deg. to the eyelets. Each depression has a chamber (14, 15) associated with it. The chambers open out into the surface (2) to form two elongated grooves whose length amount to e.g.
