Title: Cladding prefabricated wall parts - with panels accurately using crossbars, and pressed against mortared wall parts
IPC: E04C2/04
Filed: 1974-02-22
Abstract: Claddings are produced on prefabricated wall parts, with ceramics split panels. The cladding panels, with crossbars on their inner surfaces, are aligned accurate to form gaps between and are interconnected in the region of the crossbars by mortaring, and connected to the related wall part. The cladding panels are transported away from a conveyor and pushed together on ana ligning table with the crossbars downward against two alignment strips at 90 deg. to form layers, which are aligned from below by a guide acting on the crossbars, to accurate dimensions, forming equal gap spacings. Through mortar strips are then applied to the prefabricated wall part for attachment of the cladding panles, and are spaced at the panel spacing. The aligned cladding panels are taken up by a gripper with suction grippers and pressed with the crossbars into the mortar strips such that the mortar is pressed into the troughs formed by the crossbars and into the gaps. The cladding panels are automatically applied in a one-step process.
