| Zusammenfassung: | The metal section, partic. of steel plate (3) is for concrete shuttering producing prefab. components, partic. columns. It is used to form the standing surface of the component. In the centre of the metal surface is a conical, parabaloid, hyperboloid or similar non-hemispherical boss (4). The area of the surface is greater than that of the standing surface to be produced, so as to leave a peripheral edge of at lest 7 cm. In the edge there can be four or more nailing holes. |
