Floating structures formed by frameworks of large beams crop growth forces the beams to a significant bending stress and causes tension and compression, producing shear forces in the supports in addition to torsional stresses, causing problems flotation and stability with cracks and broken beams, usually caused by the deterioration of materials that form and the related links. The invention relates to a floating structure and to a method for obtaining same. The structure provides a first plurality of tubes (1) and a second plurality of tubes (2). The second plurality of tubes (2) is inserted into the first plurality of tubes (1), such as to extend through the upper portion of same, and both sets of tubes are welded together. This provision requires that the waterline of the structure is facing half of its thickness and twisting movements that the tubes tend to be offset by the downward vertical thrust sought by the crop. The ends of the tubes of the first plurality of tubes (1), as per the example, are closed in order to be used as flotation tanks when the floating structure is fitted out for the use thereof. According to the method, the first plurality of tubes (1) is locked in place on the frame (7), with the pairs of holes (4, 4&rsquo；) provided in the tubes (1) of the first plurality of tubes (1) being aligned, and a corresponding tube (2) of the second plurality of tubes (2) is inserted through each pair of aligned holes by force, the ends of each of the connection portions or parts (3) contained in the tubes (1) being welded on the periphery of the holes (4, 4&rsquo；).
