Modular building structure with integrated plants

A modular building structure with related integrated plants, including ducts, the modular building structure having a complex frame obtained by assembling a plurality of module frames, and including walls and floors implemented by panels in each module frame, wherein:

• the module frames have a substantially parallelepiped-like shape and are identified by longitudinal, vertical and transversal beams joining at respective corners, comprising a plurality of connecting knots joining module frames adjacent at said corners, and provided to connect the module frames either to a flat basement or to a roof structure;
• the adjacent beams of side-by-side module frames and the respective panels, which are fastened to said longitudinal, vertical and transversal beams in each module frame, are both spaced apart by said connecting knots, so as to create an air gap between adjacent panels of adjacent module frames, forming a wall or a floor separating the module frames;
• each connecting knot comprises three respective crossed and pass-through channels, arranged according to respective orthogonal axes parallel to said beams;
• and
• the ducts of said integrated plants are arranged in said air gaps between adjacent panels and in said pass-through channels and constrained to a respective module frame, comprising, at edges and or at corners of the module frame, quick connections for connecting ducts related to a module frame to ducts of another module frame placed side-by-side thereto.
