Abstract: The present invention relates to the design, development and implementation of a building system using connected structural panels to form walls, floor slabs, stairs and other minor elements in buildings; characterised in that it is made up of a frame defined by peripheral trusses, wherein each truss consists of a metal structure based on two parallel rods tangentially joined to a zigzag rod by the corresponding peaks and troughs thereof; a plurality of vertical trusses thus formed are distributed equidistantly or not at a predetermined distance, acting as structural elements, and a plurality of horizontal and/or diagonal transversal rods are fastened to both the front and back sides distributed equidistantly or not at a predetermined distance as reinforcement elements to stiffen the panel, the assembly defining a hollow three-dimensional box; a tightened metal framework is joined to both the front and back sides as a means of support for the mortar that is applied to the front and back sides as a covering to
