Polyfunctional structural connector and its universal fastening components making a system

A building system for building modular structures, based on the use of universal structural elements (1) and their universal fasteners (2) and (3), where all elements are of opposite ends or bipolar elements, where each end refers to the distance from the intersection point of two connectors to the center of the holes at the time of assembly, and where this bipolarity factor makes all the elements, and especially the main element of the system (1), become a universal element, and consequently, that universal element or piece can be connected to another universal element, over and over again through its opposite ends, and with one or more universal elements (1) even at the same time, with the help of its universal fastening elements (2) and (3) and the fastening piece (4), over and over again without limitations, in order to assemble an infinite number of types of structures;

• where the opposite ends of all elements have perforations out-of-phase with each other, necessary to allow the universal fastening element (4) to pass through the universal main element (1) and the fastening elements (2) and (3), making up the desired structure, thus achieving that the system has an unlimited modularity in area extension and height levels.
