BRIDGELIKE SUPPORT STRUCTURE MADE OF FIREPROOF CERAMIC BRICKS

摘要

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.

1. Bridgelike support construction made out of fireproof ceramic bricks (10, 12, 18), which features the following arrangement in its mounted state, looked at from both its free outer ends towards the inside:
1.1.1 two outer bearing bricks (10, 12) at the ends, each of which 1.1.2 features at least one generally horizontal step (10s, 12s) on their inside, 1.2.1 a keystone (18) which is arranged between the two bearing bricks (10, 12), which 1.2.2 features at least one generally horizontal step (18s1, 18s2) on both outer sides (18a1, 18a2), wherein 1.3 at least one of the horizontal steps (18s1, 18s2) of each outer side (18a1, 18a2) of the keystone (18) rests on a corresponding horizontal step (10s, 12s) of the inside (10i, 12i) of the corresponding bearing brick (10, 12) and 1.4 the bearing bricks (10, 12) and the keystone (18) are incidentally designed an dimensioned so that they 1.4.1 form an integral bridge like support construction together and 1.4.2 the support construction is self-supporting, if only the outer bearing bricks (10, 12) are at least partially resting on corresponding supports (P).
