摘要

The materials of the box support's static system are joined together by nails, double nails or by other mechanical means of connection. The materials for the manufacture of the static system may be glued together. The cavity inside the profile is filled with insulating material(B). The individual box elements are first manufactured in multiple width so that the subsequent individual wooden profiles are introduced as a double cross section to be separated after fixing of the boarding(C) on the solid wood for the individual profiles. An Independent claim is included for a device for the production of a multiple element which has the required box profiles, and fixing between the boarding and solid wood by nails or glue.
