The invention concerns an arrangement for casting of reinforced concrete pipe with compression by vibration and hydraulic pressure. The arrangement contains an outer form 2 and an inner form 3 on a spring-loaded base 1. The inner form 3 is connected to a vibrator 8 by means of tightening devices 14, 15. The one tightening device 14 contains a ring 16 with spherical working surface, which ring is fastened at the upper end of the housing 11 of the vibrator 8, and a second ring 17 with conical work surface, which ring is fastened at the inner form 3. The rings 16, 17 contain at least three gripping jaws 18, 19, 20, which are symmetrically arranged at the lower end of the housing 11 of the vibrator 8. One gripping jaw 18 can move in the axial direction of the vibrator 8 under action of an external force, while the other gripping jaws are firmly connected to the housing 11. <IMAGE> |
