Prestressed reinforced concrete pile and method for manufacturing a prestressed reinforced concrete pile

Abstract

In a reinforced concrete pile (1), at least one of the ends of the pile (1) forms a joint head (1A), from which the pile (1) can be connected to another identical or similar pile (1) to form a longer pile assembly, the pile (1) comprising an end plate (2) arranged at the joint head (1A), several longitudinal pile steels (4, 5), and at the joint head (1A) several locking sleeves (6) extending inward from the end plate (2) in the longitudinal direction of the pile (1) and / or spindles (7) extending outward from the end plate (2) adapted to operate with the locking sleeve (6), at least some of the locking sleeves (6) and / or spindles (7) connecting to the main steel (4) in such a way that the main steel (4) and the associated locking sleeve (6) or spindle (7) form a prestressed assembly.
