摘要

Variable part or device to separate dynamic building parts (7) such as flexible rails from static parts (8) such as roads, paths or pavements to reduce the friction forces arising from the sinking of the dynamic part. It has a seal connected to the part, and sections made of rubber, polyurethane or foam for example. It has a hole through which the filling liquid matter (3), such as polyurethane, bitumen or mortar, can be poured underneath. The part consists of at least two parts, the top section and the bottom sealed section, but more can be added, depending on measurements.
