Abstract

1,242,544. Rod-tensioning devices. MAURER & CO. 30 Sept., 1968 [4 Oct., 1967], No. 46224/68. Heading F2G. Apparatus for stressing a bar 11 adapted to extend through an opening in a plate 12 so as to have an annular surface on one side of the plate surrounding the opening and engaging the plate, comprises an hydraulic unit including a piston 16 and cylinder 15, the latter having a hollow sleeve part 15a terminating in an end face engageable with the other side of the plate and surrounding a nut 13 adapted to cooperate with a threaded part 11a of the bar when that part lies on the said other side of the plate, and the piston having integrally connected thereto a piston-rod 17 having a threaded portion 17a adapted to extend into a threaded bore within the threaded part lla of the bar. The end face of the part 15a presses against the said other side of the plate when the piston simultaneously pulls the bar in the opposite direction in response to the pressure of an hydraulic liquid introduced into the cylinder for prestressing the bar. The nut 13 is tightened up by introducing a tool into bores 14 in the nut.
