Title:
JACK FOR ANCHOR
Document Type and Number:
Japanese Patent JPH0470470
Kind Code:
A
Abstract:

PURPOSE: To facilitate the mounting/removing work by connecting both ends of telescopically movable cylinders to two sheets of opposed plate units and providing a center hole in the center part of each plate unit and a slit, which communicates with this center hole to introduce a tension material from the side, partly in the plate unit.

CONSTITUTION: A device is formed of two sheets of plate units 1, 2, provided with tension material inserting center holes 11, 21 in the center and slits 12, 22 respectively communicating with the center holes 11, 21, and a plurality of cylinders 3 of fluid pressure type arranged in these plate units 1, 2 uniformly on a concentric circle of the center holes 11, 21. Telescopic action of each cylinder is controlled synchronously so as to uniformly give extension/ contraction force to both the plate units 1, 2. A center hole 51 and a slit 52 are provided in a base seat plate 5 of equal shape to the plate units 1, 2, and a tension material 4 is clamped and released by mounting/removing a wedge 61 of an anchor head 6 by providing a connection part 53 insertable into the center hole of the plate unit 2 in one side of the plate 5. In this way, the device can be applied to various anchor construction works.
