<p>1. Expansible plug for anchoring in drilled holes that widen conically inwards, comprising a bolt, preferably with an external thread, which has an expander cone and is supported on the base of the drilled hole, it being possible for an expansible sleeve that is provided with longitudinal slots over part of its length to be driven onto the expander cone of the bolt, the expansible blades being limited in the longitudinal direction by a circumferential groove, characterised in that the expansible blades are divided into sections of approximately equal length by at least one notch extending transversely to the longitudinal direction of the expansible blade.</p> |
