konstrukci, nemá význam je osazovat. Na to jsou lepší klasické mostní závěry s ocelovými kotvami. Ale na veškeré rekonstrukce či částečné opravy jsou ideální,“ říká David Jelínek. Možnosti kotvení U dilatačních závěrů TENSA®CRETE není nutné žádné dodatečné vyztužení nebo kotvení. Všechna zatížení jsou přenášena přímo vazbou mezi polymerbetonem a nosnou konstrukcí. Aby byl umožněn přenos sil do sousedních konstrukčních prvků, musí mít povrch vybrání pevnost v tahu minimálně 1,5 N/mm2 (beton) nebo 3,0 N/mm2 (ocel). ROBO®FLEX by neměl být aplikován na nový beton v průběhu 14 dnů po betonáži. „Realizace závěrů je relativně jednoduchá. Nijak nezasahuje se nosných konstrukcí mostu,“ uvádí David Jelínek, v čem jsou mostní závěry společnosti mageba unikátní. Instalace Instalaci dilatačních závěrů TENSA®CRETE a vložení polymerbetonu ROBO®FLEX musí provést kvalifikovaný a certifikovaný personál. Koordinaci těchto činností na místě provádějí zkušení projektoví manažeři. Použité materiály Pro výrobu dilatačních závěrů TENSA®CRETE se používají následující vysoce kvalitní materiály - ocelový profil z oceli třídy S 235, těsnicí profil 63 Mostní závěr TENSA®CRETE typu RE Mostní závěr TENSA®CRETE typu RE-LS Výhody • Ideální náhrada za elastické a kobercové mostní závěry • Minimální dopravní zácpy v případě projektů rekonstrukcí • Kratší a snadnější montáž než u běžných spojů • Žádný dopad na nosnou konstrukci • Zlepšená ochrana proti hluku díky prvkům pro snížení hlučnosti • Práce může provádět vlastní kvalifikovaný personál expansion joint is maint and concrete connecnstalled on virtually all bridges.
