<p>The invention relates to a method and a device for producing precast components (1) that comprise a base (1') and a wall element (1'') using a concrete casting mold (2) having the shape of the precast component (1). The aim of the invention is to produce precast components in a single processing step and to allow for a firm connection between the concrete (4) and a natural stone (5). For this purpose, the concrete casting mold (2) is filled with concrete (4) with the visible side (3) of the wall element (1'') of the precast component (1) to be produced facing upward. At least one natural stone (5) is brought into a defined position in the unset concrete (4) at a depth of immersion sufficient for a reliable connection with the concrete (4) using at least one retaining element (9) and is maintained in this position until the concrete (4) has attained strength sufficient to hold the position of the at least one natural stone (5). The precast component (1) is removed from the concrete casting mold (2) when the concrete has attained sufficient strength.</p> |
