FIELD: construction.
SUBSTANCE: dowel has a rod having a neck region and a spacing portion which iis disposed with an axial offset relative to the neck region. The dowel comprises a spacing channel which extends through the neck region and the spacing portion of the rod. The rod is expandable on the spacing portion in the radial direction by inserting an expanding element into the spacing channel. The spacing channel on the spacing portion is formed exclusively by slots which come from the circumference of the rod and lead to the inner space of the rod. The spacing channel in at least one cross-sectional plane of the spacing portion is formed by two slots, which come from the portions of the rod circumference located opposite each other in the cross-sectional plane, at least partially extending with an offset relative to each other in the cross-sectional plane. The end face of at least one of the two slots forms at least two contact facets for the expanding element.
EFFECT: increased reliability of dowel fixation.
