Abstract

Device for the external turning of the fiber cement tubes, essentially characterized by comprising a threaded bar preferably metallic jable inside the fiber cement tube to turn externally, whose rod threaded at the projecting end, ending adopting a hexagonal or prismatic figure for its actuation by means of a wrench or crank, having mounted three metal bushings of nylon 6 of any other suitable material, which are arranged in a sector recayente the interior of the fiber cement tube, comprising the central bushing, mounted the central bar as a shaft by a hole through, three radial bars equidistant as arms, oriented towards the inside of the tube and three others towards the outside, whose arms will rest on the internal and external bushes at the bottom of some channels made for this purpose, the internal bushing being threaded axis 6 central bar, while the outer bushing is mounted with a through hole, providing a set of nuts threaded to the shaft and located contiguously to the outer plane of the outer sleeve to prevent its movement, coupling to the mechanism inside the fiber cement tube, rotating the central shaft to move the bushings in sense of approach or accommodation mutually until the ends of the radial arms rest firmly on the internal walls of the fiber cement tube, the center bar being threaded as the axis of the fiber cement tube itself.
