Afstandhouder in het bijzonder voor toepassing bij betonconstructies.

摘要

The element (1) has a conical shape (2) with a slightly convex outer surface and a rounded tip (3). A shallow cylindrical segment (4) is located above the cone (2). Four arrow-shaped elements (6,7) made of plastic or spring steel are molded into the top surface of the element (1). The elements (6,7) are tilted towards one another in order to accommodate a steel bar between them after it has been inserted by using a slight pressure. An independent claim is given for a steel support bar to be used in the arrangement.
