ABSTRACT:
The invention relates to a method of producing scaffolds, especially ladders. In order to provide a construction solely made of an insulant material, the rails (5) and the rungs (1) of a ladder according to the invention are wholly made of reinforced plastic and are joined to each other by means of a polymeric cold junction method. Thereby a hole (18) is provided on the side of the rail (5) and a suitable amount of a mineral or fiber reinforced monomer mixture (2) is added therein, whereafter the rung (1) is positioned thereto and the resultant whole is turned upside down, the monomer mixture being polymerized by means of heat, a catalyst and/or an accelerator. So the monomer mixture flows around the junction of the rung (1) and the rail (5), polymerizing therein and forming a tight joint between the rung and the rail.
