A TELESCOPIC STRUCTURAL SUPPORT ABSTRACT OF THE DISCLOSURE A structural support arrangement in which an inner pipe member is telescopically movable within an outer pipe member. The telescopic members have cross-sections of four-corner pipes. A self-actuated drive roller is held in elongated holes which are inclined to an axis of the support. The drive roller is knurled or has a roughened surface which abuts against the inner pipe member. The inner pipe member, furthermore, is grasped from behind by a roll bearing member which also serves as a back counter bearing for the drive roller. At least one supporting roller may be arranged with divided parts and extend over the width of the inner pipe member. A traverse member on the outer pipe member is movable about a vertical axis and retains a roller holder which extends between the divided portions of the supporting roller.
