<p>#CMT# #/CMT# The expansion anchor (11) has an anchor bolt (12) and an expansion sleeve (21). The anchor bolt has a load engagement unit (16) at an end area (14) and an expansion part (17) at another end area (15), which has a conical section (18) extending in the direction of the free end of the end area (15) for widening the expansion sleeve (21). The inner contour (22) of the expansion sleeve has an area (23) with a surface roughness, which increases in the direction of the end area (14) of the anchor bolt. #CMT#USE : #/CMT# Expansion anchor for use as fixing parts for the fixing of an article at an underground. #CMT#ADVANTAGE : #/CMT# The inner contour of the expansion sleeve has an area with a surface roughness, which increases in the direction of the end area of the anchor bolt, and hence enables to have high resistance against a passage of the expansion part through the expansion sleeve and is manufactured in simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of an expansion anchor. 11 : Expansion anchor 12 : Anchor bolt 14,15 : End areas 16 : Load engagement unit 17 : Expansion part 18 : Conical section 21 : Expansion sleeve 22 : Inner contour 23 : Area 24 : Facing end.</p> |
