Abstract (en)
[origin: WO8700227A1] Expansible device more specially intended for public works. The device comprises a sleeve (1) presenting at least a longitudinal slot which completely traverses its wall and extends from one of its extremities (9) up to the vicinity of the other extremity (11), as well as two opposite truncated bodies (2, 3) which are sunk at least partially into said sleeve (1) by its respective extremities which widen outwards and which co-operate with means (12, 14) to bring the bodies closer to each other with widening of said longitudinal slot or slots and expansion of said sleeve (1), these deformations taking place without reaching the failure stress of the sleeve material. Applications to the wedging or keying up of joints.
