| Zusammenfassung: | The dowel's expansion bushing is placed around a threaded rod inserted in the bushing's expansion core, between the strut and the core. The bushing includes a section compressible along its centerline, which includes a shearing system placed such that, after shearing, the bushing is shortened along its centerline. The bushing also includes, on its section next to the strut, coupling and axial holding spurs. The bushing is composed of a cut sheet metal blank, rolled on itself, except for the part with the spurs. |
