TENSIONING THROUGH THREAD BARS
Building site of Milano
HOTEL PORTA VITTORIA
Following the positioning of supports on conical springs, for each metal pillar, neoprene reinforced anti-vibrations were installed. They were loaded by means of special hydraulic tensioners of very small dimensions but with very high working pressures (1000 bar).
STAYS TENSIONING
Building site of Rondissone
RONDISSONE BARRIER
The main, internal and on-board stays were retensioned for a total of 50 elements. During and after the tensioning operation the readings of the vibrations in the sample were carried out between those tensioned and not so as to verify the effective influence of the retension on the entire structure.
CHAINS TENSIONING
Building site of Roma
BALBI CRYPT MUSEUM
Tensioning of 4 chains of the barrel vault in existing masonry and 10 of the new construction cover. The chains consist of fully threaded bars in stainless steel Ø 30 and Ø 32. The tensioning of the bars was performed in pairs, with load increases equal to 25% of the maximum design load.
BRIDGE ON THE CANDIANO CANAL
Tension applied to structural systems of bars, ropes and stays on different types of structures, both building and civil. Management and development of synchronized lifting systems, dedicated for each operation to be carried out. Configuration of the lifting system in complete autonomy, from the high pressure hydraulic circuit to the configuration of the supporting metal structure.
