  • Patent number: 8821090
    Abstract: The invention relates to a dowel that is composed of a strand arrangement comprising at least one first strand (12) which extends along a longitudinal axis (L) and at least one second strand (14) which extends at an angle (Y) to the at least one first strand (12) and intersects said at least one first strand (12) at intersection points. The at least one first strand (12) and/or the at least one second strand (14) is/are wound around the longitudinal axis (L) at a certain distance (171, 172) while the at least one first strand (12) is connected to the at least one second strand (14) at the intersection points. The strand arrangement is embodied such and/or is made of such a material that the strand arrangement can be expanded at an angle to the longitudinal axis (L). Such a dowel has the particular advantage of evenly distributing the pressure which acts upon the wall surface (102) of a bore. A single-size dowel can be used for several screw diameters.
