Support for supporting a structure region

A support for supporting a region of a structure, comprising a central part which has a hollow profiled rectangular tube having a square or rectangular cross section and comprising two end parts, each of the end parts being arranged so as to be able to telescope out of the central part from open ends of the hollow profiled rectangular tube in order to change a length of the support, wherein the end parts each have a hollow profiled round tube designed to be non-threaded, and inner wall regions of the hollow profiled rectangular tube form guides for the hollow profiled round tubes, the hollow profiled round tubes being guidable in the central part in a longitudinal direction of the hollow profiled rectangular tube by means of contact regions which abut the guides, in order for the end parts to be able to telescope, wherein the lengths of the hollow profiled round tubes are in each case 30 to 50% of the length of the hollow profiled rectangular tube, and for a load bearing capacity of the support to be distributed evenly over an entire length thereof a material thickness of the walls of the hollow profiled round tubes is greater than a material thickness of the walls of the hollow profiled rectangular tube.
