Abstract: A scaffolding element having a scaffolding pole, at least one fastening element being disposed or formed on the scaffolding pole. The fastening element preferably has a fastening element body. The fastening element body can be L-shaped. Preferably, the free end of the fastening element body points straight upwards when the scaffolding element is in the mounted state. A projection is disposed or formed below the free end on the fastening element body, in particular in a section parallel to the longitudinal axis of the scaffolding pole. The projection can be part of a U-shaped bead.

Abstract: The invention relates to a scaffolding element having a scaffolding pole (12i), at least one fastening element being disposed or formed on the scaffolding pole (12i). The fastening element preferably has a fastening element body. The fastening element body can be L-shaped. Preferably, the free end of the fastening element body points straight upwards when the scaffolding element (22) is in the mounted state. A projection is disposed or formed below the free end on the fastening element body, in particular in a section parallel to the longitudinal axis of the scaffolding pole (12i). The projection can be part of a U-shaped bead.

Abstract: A sealing plug has an elastic sleeve of thimble-like basic shape. A wound-up band of the sealing plug is inserted in the sleeve. The number of windings or turns of the band can be reduced by rotating the inner end of the band, wherein the outside diameter of the band, and hence the outside diameter of the elastic sleeve, widens. The band can be inserted in pretensioned state into the sleeve and can slacken after insertion into an anchor hole. The band can be expanded in the anchor hole beyond the slackened state of the band. The sealing plug further has a latching mechanism, which prevents back-rotation of the expanded sleeve. The sealing plug enables a radial expansion, and hence a sealing of anchor holes of different diameter, without shortening of the axial sealing surface of the sleeve.
