Production of pre-fabricated construction elements having a visible side comprises filling gaps between building blocks with dispersible material followed by binding agent, and removing the material after hardening of the binding agent

摘要

Production involves horizontally arranging the building blocks (1) in the desired pattern with their visible side on a composing surface (2) having a planar surface, filling the gaps with dispersible material (4) up to the desired height, filling the remaining joint height with a suitable binding agent (5), and removing the dispersible material after hardening of the binding agent. Preferred Features: The dispersible material is sand or plastic pellets. The binding agent is a mortar, an adhesive, or a self-hardening plastic foam.
