Laajennusnivellejä
Laajennusnivellejä refers to expansion joints, which are designed gaps or connections in structures that allow for movement. This movement is typically caused by thermal expansion and contraction due to changes in temperature, but can also result from vibrations, settlement, or seismic activity. Expansion joints are crucial in various types of construction to prevent stresses that could lead to cracking, buckling, or other structural damage.
Common applications for expansion joints include bridges, large buildings, pavements, and pipelines. In bridges, they are
The design of expansion joints varies depending on the expected movement and the specific structural requirements.
