(54) Construction stanchion with safety system


(57) The stanchion comprises two tubes (1) and (2) telescopically coupled to each other in which the outer tube (1) is comprised of two segments (3) and (3') welded to each other and opposite said welding being provided a protrusion (15) under which is defined a lower edge (14) which is placed inside the segment (3), thereby defining a stop for a pin (11) which is housed transversely in two opposing orifices (10) of the inner tube (2), so that it limits the upwards displacement of said tube (2) inside the outer tube (1), while a deformation (12) made on the inner tube (2) after its bottom end is inserted in the outer tube (1) provides a stop which prevents said bottom end of the inner tube (2) from exiting through the orifice (7) of the baseplate (6) of the outer tube (1). The stops determined by the pin (11) and the deformation (12) against the edge (12) of the outer tube (1) and against its baseplate (6) provide a safety system which allows the longitudinal displacement of the inner tube (2) with respect to the outer tube (1), preventing their separation.
