Abstract
A telescopic push-pull prop 10 for the construction industry has an outer tube 12 and at least one threaded rod or inner tube 14. An outer thread 22 of the inner tube 14 engages with an inner thread 24 of the outer tube 12. The inner thread 24 of the outer tube 12 is arranged at an axial separation from a free end 26 of the outer tube 12. The inner thread 24 of the outer tube 12 is produced by an at least partially circumferential reduction of the outer tube 12 over a mandrel positioned in the outer tube 12, the mandrel having an outer thread. At its free end 26, the outer tube 12 has an edge section 34 with a pass-through cross-section 32′ that is reduced with respect to a nominal width 36 of the outer tube.
