FIELD: construction.
SUBSTANCE: composite dowel for fixation of heat insulation boards includes a fastening element made of polymer material, comprising a spacer part, which represents a rod with a longitudinal hole, and coaxially inserted into it with one of ends of the remote part, which represents a rod with a longitudinal hole and a pressing plate at the other end. On the outer surface of the remote part there is a ledge made so that during connection of two parts it rests against the end of the spacer part, and on the wall of the spacer part hole, in area designed to hold the remote part, there is a longitudinal rib, providing for tension in connection between parts.
EFFECT: increased bending stiffness of dowel parts connection area.
