    DESCRIPTION OF THE INVENTION
    The present invention (Figure 1) consists in the use of four base flanges (1) that resolves the connection between a square or rectangular section pillar (2) and the foundation, so that no previous operation is necessary in the pillar and also all the elements, such as both the base flanges and the pillar, can be disassembled and reused in future applications.
    The structural elements (Figure 2 and Figure 3) that each of the base flanges have are: a wall (3), several brackets (4), a base (5) and a backrest (6). In turn, the backrest has several threaded holes (7) that facilitate the subsequent connection between the pillar and the base flange. The base, meanwhile, has several holes (8) that allow the subsequent anchoring between the base flange assembly with pillar and the foundation.
    The connection between the pillar and the base flange is carried out in the area of the backrest of the base flange (Figure 4). For this, a wedge with trapezoidal shape (9) and clamping screws (10) are used. The tightening screws push the wedge towards the inner walls of the abutment, fixing it in its final position. The use of the wedge, with this trapezoidal shape, allows the system to be valid for different pillar thicknesses of square or rectangular section tubes.
    The final connection between the base flange assembly with pillar and the foundation is carried out in the holes (8) of the base flange base (Figure 5). To do this, the anchor bolts (12) with their corresponding washers (11) are used. These washers have the function of producing a distribution of the bolt tightening stresses as evenly as possible, always below the elastic limit of the material used. For each pillar, four base flanges will be necessary, one for each corner of it.
    In the present invention, the transmission of the bending moments between the pillar and the foundation is carried out through the base flanges by the so-called "lever effect" that occurs between the pillar and the base flanges. To visualize it more graphically, in figure 9, it can be seen that if a force (F) is applied at the upper end of the pillar (2), the bending moment that will be transmitted to the foundation will be the product of that force (F) and the height of the pillar (h).
    The transmission of this bending moment (F xh) between abutment and flange is carried out by two forces: one of compression (Fc) that originates from the outside of the abutment, at the top (13) of the contact area between abutment. and base flange, and another force (Ft) opposite the previous one, which supports the trapezoidal wedge (9) of the base flange.
    The four trapezoidal wedges, placed in each of the inner corners of the abutment, ensure that whatever the direction of the force applied to the upper end of the abutment and therefore the direction of the resulting bending moment, the system will work correctly.
    The final transmission of the bending moment to the foundation is done through the anchor bolts, using the reaction forces in Rc and Rt (Figure 10).
    In another aspect, this removable base allows to adapt to different nominal sizes of pillar section, always using the same base flanges. This feature is one of the main advantages of this system. The present system is usable in a wide range of nominal sizes of square or rectangular section tube pillar sections, which avoids having to have a different base flange size for each nominal size of square section tube pillar section or rectangular
    The system allows for fully removable anchor bases, in which the elements used (pillar and base flanges) are fully reusable at the time they are disassembled, without the need for any previous operation on the pillar. In addition, the conception of this system allows the same base flange sizes to be used, adapting the base flange to the size of the pillar section, which leads to greater standardization, with the consequent simplification and cost savings DESCRIPTION OF THE FIGURES

    A description of the embodiment of the invention follows, with reference to the numbering adopted in the figures.
    First of all (Figure 4), the tightening screws (10) are inserted into their corresponding holes (7) without tightening them, simply by positioning them. Then the trapezoidal wedge (9) is inserted into the base flange (1).
    Subsequently, the pillar is positioned horizontally in a workstation, such as a table, for the operator's comfort during assembly. The base flange is inserted into a corner of the abutment (Figure 6), with the wedge and the screws already positioned previously in their corresponding place. The screws are tightened firmly, with the tightening torque corresponding to the quality of the screws. These are pushing the wedge towards the interior walls of the pillar. Care must be taken to leave the joint between the abutment and the base flange positioned and leveled correctly. This procedure is repeated in the remaining corners of the pillar, thus completing the pillar anchor base with the four base flanges (Figure 7).
    The assembly is then placed in an upright position and positioned in the area where its location is desired. The connection between the base flange and the foundation (Figure S, to simplify the figure, only the base flange has been represented in one of the corners of the pillar, since the process would be similar for each of them) is carried out by means of anchor bolts (12) with their corresponding washers (11), so that the washers are placed in their correct position and the anchor bolts (12) are inserted into the holes (8) intended for this purpose, tightening them firmly with the tightening torque corresponding to the quality of the screws and strength of the foundation. This procedure is repeated on the remaining base flanges of the remaining corners of the abutment.
    Finally in Figure 8, the final result of the complete anchor base can be seen.
