Abstract

In a concrete structure, consisting of at least two upright precast concrete elements (1, 1′), it is intended to develop the butt joints between the precast concrete elements in such a way that forces can be absorbed better in at least two directions. For this purpose, it is proposed that at least two tongue-and-groove connections (4, 9; 5, 10) are provided in the region of at least one butt joint (2, 2′) between the precast concrete elements (1, 1′), wherein one of the tongue-and-groove connections (4, 9) is arranged such that it is turned with respect to the second tongue-and-groove connection (5, 10) in a range between about 1° and about 179°, and wherein the butt joint (2, 2′) is of an offset form, and the tongue-and-groove connections (4, 9; 5, 10) are provided in the regions of the offset that run substantially parallel to the surface (3) of the precast concrete elements (1).
