Bracings
Bracings for expansion joints are available in various designs, depending on the required function, nominal width and operating pressure.
Defined tensioning – defined protection
Bracings are definingthe movement and thus protects the expansion joint from damage caused by overstretching or excessive compression or absorbs the reaction forces from the expansion joint, protecting neighbouring components from additional forces.
