The invention relates to an arrangement of displacement bodies (1) for introduction into reinforced-concrete structural parts (13), in particular into reinforced-concrete slabs (13), wherein the displacement bodies (1) have a basic shape in the form of a truncated cone or of a polygonal truncated pyramid, and having a base surface (2) and a top surface (3), and are arranged in a linear arrangement in relation to one another in the reinforced-concrete structural part (13), in which arrangement a number of displacement bodies (1) in the form of truncated cones or of polygonal truncated pyramids are arranged linearly (17), with the base surface (2) and top surface (3) of respectively adjacent displacement bodies (1) being oriented in alternating fashion in relation to one another, and respectively adjacent displacement bodies (1) are spaced apart from one another. The displacement bodies (1) here have basic shapes in the form of truncated cones, it being possible for the base surface (2) and top surface (3) to be designed in the form of a circle or ellipse, or with a continuously curved base surface, or to be polygonal. |
