Abstract: The self-bearing prefabricated construction element for erecting external walls in buildings, composed of external and internal panels integrated with the insulating material which goes in between, characterized in that the external panel (1) forms the face of architectural concrete which serves as the facade finishing layer, and the internal panel (2) is preferably made of structural concrete, where the insulation (3) in between the panels and integrated therewith is made of a foam material of density ranging from 10 kg/m3 to 55 kg/m3 and features at least two slots (4) in the vertical side zones.

Abstract: The modular platform for offshore constructions, composed of more than two separate buoyancy elements partially immersed in water, which move along with the water wave movement and which, in the part above the water level, are connected to the structural elements forming a rigid horizontal spatial structure, characterized in that the buoyancy element (1) is given the shape of a cuboid or cylinder having at least one vertical hollow (2) to accommodate the structural element, i.e. piston (3), which forms the axis along which the buoyancy element (1) moves, and which is connected to the horizontal structural element (4) fitted to take external loads.
