The invention relates to a fixing element (10) for anchoring in a drilled hole (30, 32) having an undercut (28) in a laminated body (24, 26), for example, laminated glass. The fixing element (10) has an expander cone (14), onto which an expansion ring (16) can be pushed. To be able to compensate for misalignment between the layers (24, 26) of the laminated body (24, 26), the drilled hole (30) in an outer layer (24) is drilled with a larger diameter than in a further layer (26) of the laminated body (24, 26). The invention proposes constructing a washer (18) of the fixing element (10) with an injection opening (22), through which the gap between a threaded shank (12) of the fixing element (10) and the wall of the drilled hole (30) in the outer layer (24) of the laminated body (24, 26) can be filled with a sealing compound (26)2. (FIG. 2).
Fixing element for laminated glass, having a threaded shank with an expander cone, having an expansible element with a central hole slidably placed on the threaded shank, which expansible element is expandable by being pushed onto the expander cone, and having a washer placeable on the threaded shank, characterised in that the washer (18) has an injection opening (22) which extends through the washer (18) and, on the side of the washer (18) facing the expander cone (14), discharges towards the circumference of the threaded shank (12), so that a filing compound (36) can be introduced through the injection opening (22) in the washer (18).
Arrangement with a fixing element anchored in a panel-form laminated body, characterised in that an outer layer (24) of the laminated body (24, 26) has a drilled hole (30) passing through it, which drilled hole opens into a drilled hole (32) having an undercut (28) in a further layer (26) of the laminated body (24, 26), in that the fixing element (10) comprises a threaded shank (12) with an expander cone (14), the expander cone (14) being located in the undercut (28) in the further layer (26) of the laminated body (24, 26), in that an expansible element (16) is pushed onto the expander cone (14) and thereby expanded so that the expansible element (16) engages with a positive fit behind the undercut (28), and in that a washer (18) that covers the drilled hole (30) in the outer layer (24) of the laminated body (24, 26) is placed on the threaded shank (12), in that the drilled hole (30) in the outer layer (24) of the laminated body (24, 26) has a larger diameter than the threaded shank (12) of the fixing element (10) and than the drilled hole (32) in the further layer (26) of the laminated body (24, 26), in that the washer (18) has an injection opening (22) which is accessible on the outside of the washer (18) and which discharges into the gap between the threaded shank (12) of the fixing element (10) and the wall of the drilled hole (30) in the outer layer (24) of the laminated body (24, 26), and in that a filling compound (26) is introduced through the injection opening (22) into the gap.
