  • the disclosed solution provides at least the following advantage: demounting of the parts or entities/elements making up the building structure without any damages (i.e. upcycling for circular economy value), and for clean dissociation of the materials being a mixture of parts made of concrete or metal, such as steel, or made of both concrete and metal (to enable cradle-to-cradle approach).
  • the disclosed solution provides at least the following advantages: replaceable joint tightening products in the form of separate connecting members/elements and fasteners as they are detachable and replaceable joint water sealants and/or fire protection products as they are easily assembled and disassembled by the thereby achieved repeatable detachability of the floor of the building structure and its joints.
  • the disclosed solution provides at least the following advantages: reversible connecting members and elements and fasteners; improved tolerances absorption by spacer elements being added as part of the horizontal support beam top flanges to receive and position the concrete plates correctly and safely and in a robust repeatable way; dissociation of positioning and fixation entities, such as the spacer elements and the connecting members/elements and fasteners, that enables a clean dissociation of the entities/elements making up the building structure(s) and its floor(s), and provides damage free demounting and full value preservation for second life cycle when erecting the building structure(s) and all of the parts making it/them up at another site or to convert for example a parking or industrial building into an office building instead and vice versa.

This ensures that the concrete plate(s) can remain totally undamaged after assembly/reassembly and disassembly. In a current standard building, such local small drilling and/or cutting actions and/or fixations are simply standard, but in reality it incur damage to the concrete and/or metal/steel building elements.
