摘要

The device (1) for the supporting of pipelines, especially under bridges, consists of two vertically extending tubes (2), between which is installed a cross member (3) connected to the vertical tubes. The vertically extending tubes are each formed by an outer tube (4) and an inner tube (5) telescopically installed inside the latter. The cross member is fastened preferably by welding to preferably the outer tubes' end sections (6) furthest from the inner tube. The tubes may have a rectangular or square cross section.
