SUPPORTING ELEMENT TO BE USED IN BUILDING CONSTRUCTIONS |
摘要 |
Supporting element for building constructions, comprising an outer tube (3) made of sheet steel, in which an inner tube (1) can be telescoped, the outer tube having ridges (13) intentionally provided by way of deformation and constituting a guide for the inner tube (1). As a result, lateral damages such as dents caused during construction operations may be absorbed by the wider portions of the outer tube (3) without impeding the telescopic capability of the inner tube (1). For coupling this element, a ring (23) is welded to the outer tube (3) which ring has a widened portion (31) at the location of each ridge (13), so that between the tube and the ring a cavity (33) is created which may accommodate the hooked end (35) of a coupling element (37). This end can be locked in that cavity by means of a lever (39) clamped with its end portion (54) against the bottom of the ring (23) by way of a displacing mechanism (41). |
