| 摘要 |
The invention relates to an expansion dowel (1) which is made of at least two different plastics, comprising a main body (2) made of the first plastic, which main body is at least partially surrounded by a sheath (3) made of the second plastic. The main body (2) has an expansion region (5) which extends along a longitudinal axis (L) with at least two expansion tongues (11, 12) separated from one another by a first slot (13), and a sleeve (6) which is disposed in the direction of introduction (E) at the front on the expansion dowel (1). The sleeve (6) is connected to the expansion region (5) and is at least partially surrounded by a sheath body (18) formed by the sheath (3). In order to produce an expansion dowel (1) having improved spreading behaviour, according to the invention at least one wing element (22) is disposed on the sheath body (18) and extends in the form of a cantilever arm from the sheath body (18) against the direction of introduction (E) and predominantly in the longitudinal direction (L). |
