Directional coupling device between the vertical and horizontal Elements, notably for the Construction of tubular scaffold.

摘要

Coupling device of horizontal and vertical elements of tubular scaffolding. Consists of a geared ring (1), on a vertical Element, which has four radial Arms (2), each of which is adapted to receive a flange (4, 15) connected to the end of the corresponding horizontal tubular element.The flange (4) The Extreme horizontal element can rely on the Ring Body (1) through (6) of prominences, or of another type of flange (15) whose prominences (17) supported on prominences (6) of the flange (4), although there is another type of Ring (1) which have Ribs which allow Flanges (415) the horizontal elements are equal and direct support on the ring (1). The Flanges (4, 15) are welded to the tubular Elements (5, 16) and these are fixed to the ring (1) by Keys which are introduced into the housing (9) arranged through holes (7, 8) in the Flanges.
