摘要：
Device for fixing a rail onto a slab of concrete comprising a metal chair fixed onto a metal base with interposition of a resilient sole, by means of clamps which are tightened by rotation on an inclined plane and which come to fix simultaneously the rail onto the metal chair and the metal chair onto the base. Preferably the clamps press against pillars formed on the base.
