PCT No. PCT/SE86/00492 Sec. 371 Date Jun. 29, 1987 Sec. 102(e) Date Jun. 29, 1987 PCT Filed Oct. 28, 1986 PCT Pub. No. WO87/02726 PCT Pub. Date May 7, 1987.Means for joining concrete piles (10) comprising a fixed end shoe (11) on each of the adjacent pile ends, and elements for joining the piles at the end shoes. Said elements include a number of guides (12) opening at the outside of the pile close to the adjacent pile ends, guides in one pile being located opposite to guides in the pile, and locking members (18), spanning the joint between the piles, which are driven from the outside into guides located opposite to each other in the pile ends to press said ends together by wedge action between guides and locking members. The guides (12) are dimensioned in relation to the locking members (18) so as to effect plastic stretching of the locking members after an initial displacement when the locking members are driven into the guides. |
