Assembly kit for constructing open staircase, comprises metal holder with ceramic or plastic insert having top surface lying flush with upper edge of holder

摘要

The dimensions of the metal holder (10) correspond with the width and depth of a step. It (10) forms an upwardly-open casing (13). This contains a filling (15). Fastenings attach the step to a base or fixed side face. The filling is a prefabricated molding (15) of ceramic or plastic, which is fitted into the casing. The upper surface (28) of the molding blanks-off the opening, flush with the sides. The holder is tray-like; a mat deadening the sound of footsteps is located between its base and the underside of the molding.
