Abstract (en)
[origin: EP0752296A1] The expanding anchor (18,24) is movable in relation to the tensioning appliance (40,54) in the longitudinal direction of an inserted straddling tie-piece (30,32). The anchor moves the expander sleeve (34) which is on the shaft (28) of the tie-piece towards the tie piece head (38) to expand it. The anchor has a collet (54), and a clamping cone (52) movable by a clamping piston (40). The expander sleeve has a piston (18) for moving the expander sleeve towards the tie piece head. An excess pressure valve (74) in a fluid duct (70) leading from a clamping piston pressure chamber (66) to a straddling piston pressure chamber (72) opens the fluid duct when the clamping pressure in the clamping piston pressure chamber is reached.
