Definitions

  • the present invention relates to the standardization of a construction system mainly based on a "prefabricated structural panel" for building which can be used as a wall and as a slab when assembled with a series a different materials, thus performing seismic, thermal, hygrometric, and acoustic functions.
  • the invention relates to a prefabricated structural frame to be used in civilian, commercial or industrial buildings, which forms outer and inner walls and slabs when assembled with an accurate manufacturing method in the fashion of an assembly line.
  • the present invention relates to a completely industrialized construction system which can be used to build any housing type and/or building project without limitations or restrictions when preassembled in a factory or on site.
  • Multilayer wall panels are known, for example, from CH699149B1 , EP0921243A2 , EP1273729A2 , US6625948 B2 , EP1892350A2 and PCT/IB2018/058161 to the same inventor.
