摘要： The invention relates to a construction tube (1) which has a circular cross section, wherein the circular cross section comprises two circular stretches (2) and two flat stretches (3) diametrically opposite from each other which define two parallel planes interrupting the circular stretches (2). It enables the advantages of construction tubes with a circular cross section and the advantages of tubes with a polygonal cross section to be combined. The construction tube (1) can be joined to a connectable element, which is preferably selected from another construction tube (1) and an output shaft (30) of a reducer (31) of a solar tracker, in particular, using inner parts (5) and/or clamps (7, 8). The construction tube (1) of the invention has a special application in solar collection systems, making up a torsion shaft (22) of a solar tracker.

摘要： The tubular shaft splicing device comprises adjacent first and second end portions (11, 21) of two tubular shaft stretches (10, 20), one or more splicing plates (30, 40) superimposed to opposite sides of the first and second end portions (11, 21) of the tubular shaft stretches, and passing-through locking members (51, 52) inserted in aligned locking holes (13, 14; 23, 24; 33, 34; 43, 44) formed in the first and second end portions (11, 21) of the tubular shaft stretches (10, 20) and in the one or more splicing plates (30, 40). The passing-through locking members have a rectangular or trapezium cross-section and the locking holes formed in the first and second end portions of the tubular shaft stretches and in the one or more splicing plates have a conjugated rectangular or trapezium shape, with two sides of the rectangular or trapezium shape being parallel to a longitudinal axis of the tubular shaft.
