Grounding segment for grounding metal wall segment of sound protection wall i.e. post structure, utilized in railway route, has holding section supported at lower side of protective cap as counter bearing for application of initial tension

摘要

The segment has a contact spring (5) made from metal, and a protective cap (15) made from metal i.e. aluminum alloy, and connected with a double-T-metal stand (1) that holds wall segments (3, 3.1) in U-shaped retainers (2, 2.1). The contact spring has spring arms (6, 6.1) that extend over a section of upper sides (11, 11.1) of the wall segments. A holding section (7) is supported at a lower side of the cap as a counter bearing for application of initial tension acting on contact sections (12, 12.1) that lie at the upper sides of the wall segments when the cap is connected to the stand.
