An expansion wedge anchor (80) for insertion in a hole (H) delimited by a
wall comprises an expander member (32) and an expansion number (34), the
expander member being provided at a leading end of the expander member,
the expander member comprising a flaring end (40), the expansion member
being expandable at a trailing end (48) thereof and being adapted to
engage the wall of the hole when the expander member is positioned in the
hole, wherein upon longitudinal withdrawal of the expander member from the
hole, the expander member displaces longitudinally relative to the
expansion member with the flaring end thereof gradually causing the
trailing end of the expansion member to expand, whereby a trailing edge of
the expansion member engages the wall of the hole. The trailing end is
adapted, when expanded by the flaring member, to extend at an angle with
respect to a longitudinal axis of said expander member. In the method of
setting the expansion wedge anchor in the hole, the following steps are
found: (a) providing an expander member and an expansion member; and (b)
displacing the expander member such as to cause a trailing end of the
expander member to engage the wall of the hole.
