Abstract
A combination for securing an anchor member in a receiving material includes a hardenable reaction resin mortar containing filler material and a sleeve-like dowel member with openings extending through the dowel member wall so that mortar injected into the dowel member can escape laterally outwardly through the openings. The ratio of the diameter of the openings through the dowel member wall to the mean particle diameter with the filler material is in the range of approximately 1.5 to 12.0, and particularly 1.8 to 5.6.
Claims25
A combination for securing an anchor member, such as an anchor rod, in a hard receiving material, comprising a hardenable reaction resin mortar containing filler material, and an axially elongated sleeve-shaped screen-like wall forming an axially extending dowel member having openings along the axial length thereof and extending through said wall transversely of the axial direction of said dowel member and said dowel member serving to receive said mortar so that said mortar flows outwardly through the openings and said dowel member containing said mortar arranged to receive and secure the anchor member, wherein the improvement comprises that said filler material in said mortar has a mean particle diameter in the range of 0.01 to 0.5 mm, and the ratio of the diameter of said openings through said dowel member to the mean particle diameter of said filler material is in the range of approximately 1.5 to 12.0 so that said filler material passes through said openings.
