Spacer for cladding elements in underground construction

摘要

The spacer has an attachment region (1) facing the subsoil and a receiving region (2) for the cladding elements. Both regions can be positioned relative to one another so that they can allow changes in the length of the spacer. The attachment region has an outer thread (3) and the receiving region an inner thread for connecting the two regions together. Alternatively, the two regions made slide telescopically in one another. A distancing piece can be placed between the two regions. The attachment region is formed as a shaft and has an outer thread (4) for screwing into the subsoil.
