Patent ID: 7818940

Claim:
A sealing element for sealing a hole formed in a water-impermeable sealing layer ( 8 ) of a structure for a fastening element ( 5 ) chemically anchorable with a curable compound, the sealing element comprising: a contact area ( 18 ) for contacting the water-impermeable sealing layer ( 8 ); a flange area ( 19 ) spaced from the contact area ( 18 ) and forming a through-opening ( 12 ; 42 ) for the fastening element ( 5 ); a cap-shaped space ( 21 ) for receiving the curable compound ( 10 ) exiting from a borehole and extendable between the contact area ( 18 ) and the flange area ( 19 ), the cap-shaped receiving space ( 21 ) having an outer diameter (C) at the contact area ( 18 ) that corresponds to from two-times to six times an inner diameter (D) of the through-opening ( 12 ; 42 ); spring blades ( 15 ; 45 ) surrounding the through-openings ( 12 ; 42 ) and projecting thereinto for clampingly engaging the fastening element ( 5 ); and a boundary wall ( 22 ) connecting the contact area ( 18 ) and the flange area ( 19 ), the boundary wall ( 22 ) having, proceeding from the contact area ( 18 ) of the sealing element ( 11 ), a first wall portion ( 23 ) and at least a second wall portion ( 24 ) adjoining the first wall portion ( 23 ), wherein the first wall portion ( 23 ) encloses a first angle (A) with a through-axis ( 13 ) of the through-opening ( 12 ), and the second wall portion ( 24 ) encloses a second angle (B) with the through-axis ( 13 ), wherein the first angle (A) is greater than the second angle (B), wherein the boundary wall ( 22 ) is provided, at least in some areas of its side facing the receiving space ( 21 ), with a flow contour ( 25 ) for a uniform distribution of the curable compound ( 10 ) exiting from the borehole ( 9 ), wherein the flow contour ( 25 ) has at least two steps ( 26 ) which are arranged in a radially circumferentially extending manner.
