DETAILED DESCRIPTION OF THE INVENTION

[0030] The attached figures show a modular system of construction, conduction and fixation of tubular structure elements or, simply, just modular system (100), in addition to a corresponding tubular structure (150).

[0031] A modular system (100) according to the invention comprises one or more modules (200, 300) crimped together to form a tubular structure (150).

[0032] Each module (200, 300), preferably a metal tube, has in the region of its lower end a fixing crown (210, 310) provided with two or more through or threaded holes or the like (215, 315), preferably arranged in a equidistant manner along its perimeter face, wherein said fixing crown (210, 310) is positioned at a distance from the lower end of the module (200, 300), herein called the crimping depth (P.sub.200, P.sub.300), the measurement of which corresponds to a value between 0.5 and 3.0, preferably 1.5, times the diameter measurement (D.sub.200, D.sub.300) of the module (200, 300).

[0033] In the region of its upper end, each module (200, 300) has an annular fixing flange (230, 330) provided with through or threaded holes or the like (235, 335) and which covers the entire perimeter of this upper end, in addition to crimp fins (240, 340) arranged inside the upper end at a fin distance (P.sub.240) which is equivalent to a crimping depth (P.sub.200, P.sub.300) decreased from 10 to 100 millimeters, preferably from 50 millimeters, in which the crimping depth (P.sub.200, P.sub.300), in turn, corresponds to a value between 0.5 and 3, preferably 1.5 times the diameter measurement (D.sub.200, D.sub.300) of the corresponding module (200, 300).

[0034] The crimp fins (240, 340) serve to guide, center and conduct with precision the crimp of a smaller second module (300) into a larger first module (200), until the fixing crown (310) abuts the annular fixing flange (230), which serves as a vertical stopper for the smaller second module (300).

[0035] The crimp fins (240, 340) are preferably polygonal in shape, having a total height (241, 341) composed of the sum of a lower height (242, 342) and a higher height (243, 343), a larger lower width (244, 344) and a smaller upper width (245, 345), in addition to a thickness (246, 346).

[0036] For the purpose of facilitating the description and understanding of the present invention, reference will be made alternately to one or two of the modules (200, 300) and their components, depending on the greater or lesser complexity of the explanation. In any case, what will apply to the elements of the larger module (200) will also apply to the elements of the smaller module (300) and vice versa.

[0037] The measurements of the crimp fins (240) are such that the diameters formed between the edges facing into the tube of the larger module (200), specifically of a higher diameter (D.sub.240-A) formed between the edges of the smaller upper width (245) and a lower diameter (D.sub.240-8) formed between the edges of the larger lower width (244), are such that the lower diameter (D.sub.240-8) represents between 80 and 90%, preferably 85%, of the higher diameter (D.sub.240-A); the higher diameter (D.sub.240-A) represents between 85 and 99%, preferably 97%, of the inner diameter of the larger tube (D.sub.200); and the lower diameter (D.sub.240-B) is between 0.25 and 1.5%, preferably 0.85% greater than the outer diameter of the smaller tube (D.sub.300-E);

[0038] In addition, to allow smooth conduction of the module (300) inside the larger module (200) during the crimping, the measures of the crimp fins (240) must be such that the higher height (243) is between 65% and 85%, preferably 75%, of the total height (241), with the smaller height (242) representing between 65 and 85%, preferably 77%, of the larger lower width (244), the measurement of which respects the relations and proportions defined above for both the higher diameter (D.sub.240-A) and for the lower diameter (D.sub.240-8).

[0039] The crimp fins (240) must be arranged in a spaced and equidistant manner along the internal perimeter of the modules (200, 300), wherein the crimp fins (240) arranged parallel to the longitudinal axis of the modules (200, 300) forming a kind of internal crown and, among themselves, an angle (δ) that can vary according to the diameter and thickness of the tubes of each module (200, 300), this angle (δ) being typically from 5 to 45°.

[0040] Once it is crimped and abutted, the position of the smaller module (300) can be adjusted by rotating it inside the bearing formed by the upper end of the first module (200), by the crimp fins (240), and by the annular fixing flange (230), until the through or threaded holes or the like (315, 235) coincide and the union can be completed by fixing the modules (200, 300) through suitable fixing elements (PF). It should be noted that the rotation of the smaller module (300) can also serve to adjust the position of any additional parts fixed to the tubular structure (150), such as, for example crosspieces, insulators, transformers and the like (not shown).

[0041] To ensure the maintenance of the circularity of the lower end of each module (200, 300), each module (200, 300) can be equipped with a lower dimensional stabilization ring (250, 350), fixed inside it at a stabilization distance (P.sub.250, P.sub.350) which is equivalent to a crimping depth (P.sub.200, P.sub.300) decreased from 10 to 100 millimeters, preferably from 50 millimeters, in which the crimping depth (P.sub.200, P.sub.300), in turn, corresponds to a value between 0.5 and 3, preferably 1.5 times the diameter measurement (D.sub.200, D.sub.300) of the corresponding module (200, 300).

[0042] At its upper end, each module (200, 300) can also be equipped with a dimensional stabilization ring (260), which will serve as an additional structuring element to the annular fixing flanges (230, 330) or any other ring fixed inside it, or close to the upper end, or at a random distance to be chosen between the upper end and the dimensional stabilization ring (260, 360).

[0043] The crumpling or crushing of tube ends is a recurring problem in metal tubes built with relatively small thicknesses in relation to their large diameters. The dimensional stabilization rings (250, 350, 260, 360), together, ensure that the circular shape of the tubes of each module (200, 300) is maintained, especially at its ends, even in severe handling and transport conditions.

[0044] The crimp fins (240) can be arranged on the dimensional stabilization ring (260) fixed inside the region of the upper end of each module (200, 300), at a dimensional stabilization distance (P.sub.260, P.sub.360) which is equivalent to a crimping depth (P.sub.200, P.sub.300) decreased from 10 to 100 millimeters, preferably from 50 millimeters, in which the crimping depth (P.sub.200, P.sub.300), in turn, corresponds to a value between 0.5 and 3, preferably 1.5 times the diameter measurement (D.sub.200, D.sub.300) of the corresponding module (200, 300).

[0045] The crimp fins (240) can also be positioned inside the respective module (200) without the presence of a dimensional stabilization ring (260), a situation shown in particular by the attached FIG. 7.

[0046] For fixing the tubular structure (150) to a substrate, any suitable means known from the prior art, such as the use of a ground fixing crown (500) to which anchoring hooks (510) can be fastened through fixing elements (511), can be used in the first module, seen from the bottom up. In the current example, the larger module (200) was considered to be the first and external fins (540) were used to assist in structuring the fixation—see attached FIG. 9.

[0047] It should also be noted that the tubular structure (150) can be formed by one module (200) or by two modules (300) or by several modules, ending in an upper, terminal or top n-th module (n), forming a tubular structure (150) of several modules (200, 300, n).

[0048] All elements added to the modules (200, 300), such as fixing crowns (210, 310), annular fixing flanges (230, 330), crimp fins (240, 340), upper dimensional stabilization rings (250, 350), dimensional stabilization rings (260, 360), must be fixed by appropriate fixing means, which can, for example, be welded through weld beads (S) or any similar suitable to the application and dimensions of the elements.

[0049] To allow the crimping of the modules (200, 300) and the assembling of the corresponding tubular structure (150), the diameters (D.sub.200, D.sub.300) of the modules (200, 300) must be such that the diameter of a first module (D.sub.200) is always larger than the diameter of a second module (D.sub.300), which, in turn, should have a diameter larger than the next adjacent module and so on, up to a last or n-th module (n) of diameter (Do).

[0050] The relation between the diameters (D.sub.200, D.sub.300, D.sub.n) of the modules (200, 300, n) should be chosen in such a way that the diameter of the first module (D.sub.200) is equal to the measure of the diameter of a second adjacent module (D.sub.300) plus a suitable value for the diameter, for example between 50 mm and 500 mm, preferably 150 mm.

[0051] This transition relation between the diameters will essentially depend on a set of factors such as the tube thickness of each module (200, 300), the crimping conditions, the total number of modules, the segmentation intended for the modules, the applied loads and the respective safety coefficients, the number of fixing elements (PF) etc.

[0052] Finally, it should be noted that tubular structures (150) like those of the present invention provide means of building larger and more resistant high structures than their prior art pairs, considerably increasing the possible free interspaces between each structure. In this way, it is possible to drastically reduce the environmental impact, more specifically, to reduce and practically eliminate the need for deforestation of the patches of vegetation (V) under the transmission lines (LT) in relation to what happens in the current case of lattice towers (TT), as shown in the attached FIGS. 10 and 11.

[0053] FIG. 10 shows schematically a section of a transmission line (LT) known from the prior art, with interspaces between the lattice towers (TT) that rarely exceed 350 meters and, in some extreme cases, reach 540 meters, but already with great strain on the material.

[0054] FIG. 11 schematically shows a section of a transmission line (LT) with tubular structures (150) equipped with seven modules (200, 300, n) crimped according to the invention, allowing, according to the practice of installations already carried out, free interspaces even greater than 1,200 meters, practically dismissing the removal of vegetation (V) under the transmission line (TT).

[0055] In a preferred embodiment of the present invention, the modules (200, 300, n) are manufactured in metal, preferably in steel.

[0056] In another preferred embodiment of the present invention, the modules (200, 300, n) are coated with polymeric resins or the like, the resin being preferably a polypropylene-based resin or the like.

[0057] In yet another embodiment, the modules (200, 300, n) are protected by a galvanizing layer (preferably hot dip galvanizing).

[0058] In another embodiment the modules (200, 300, n) are protected by suitable paint, preferably epoxy-based.

Final Considerations

[0059] It is evident that the measures and relation between measures described for the present invention can vary according to the dimensioning of the tubular structure (150). Exhaustive practical tests, however, have shown that these dimensions and their relations are highly efficient and effective in the robustness, safety, and practicality provided by the tubular structure (150). In addition, the construction of the tubular structure (150) of the present invention and said measures and their relations, are highly reliable and reproducible.

Such modifications should be considered to be within the scope of the present invention. Consequently, the particular embodiments described in detail above are only illustrative and exemplary and are not limiting as to the scope of the present invention, which must be given the full extent of the appended claims and any and all equivalents thereof.
