These systems are designed to be able to allow large structures controlled movement. This can be used to help make a structure resistant to natural forces such as high winds, earth tremors etc, or to build in designed movement to allow for expansion of components from changes in temperature, such as with bridges.
This project required the application of two types of polymer, PTFE and PEEK, embedded in a carbon steel base plate
Both these materials are used for their coefficient of friction, which also makes them hard to bond, and the PEEK requires extra mechanical fixing with the use of counter-sunk bolts.
These are then matched with a larger base plate made from a mirror polished steel, allowing free movement with high load bearing capabilities.
Clever stuff eh?. See, it’s not just Rubber, we do more than it says on the tin!
