Wall anchoring device for locating stair steps on support components, particularly stairwell walls

摘要

The hole (20) in the stair support component is filled with a hardenable material and in it is a casing (30) with recesses. The anchoring unit as a bar component is connected to the loading unit. The diameter of the casing is so selected that between the inner contour of the casing and the outer contour of the anchoring unit is a clearance (S). With the anchoring unit inserted in the casing also outside the casing hardenable material is present. The anchoring unit is formed as a round bar, particularly a threaded bar (16.2), which is screwed into an inner thread (24) on the face side of the locating unit. The clearance (S) is particularly up to 3 mm. The hardenable material (22) is plastic mortar, particularly a two-component mortar. The anchoring unit or the casing is enclosed in a layer of sound-insulating material (40), approximately 3 mm thick and with a Shore hardness of approximately 70 sh.
