Abstract

The invention relates to a bridge-like supporting structure made of fireproof ceramic stones, wherein two outer, end bearing stones have a largely horizontal step on the inner side of the outer, end bearing stones and a keystone arranged between the two bearing stones has at least one corresponding step on the two outer sides of the keystone. By means of said structure, thermal expansions can be better compensated.
