Zusammenfassung:PROBLEM TO BE SOLVED: To provide a ceramics fiber brick capable of suppressing time degradation as compared with a conventional technique and maintaining heat insulation for a long period of time and a furnace inner lining structure using the same.SOLUTION: A ceramics fiber brick 31 includes: a brick body 10 obtained by folding down a sheet-like ceramics fiber blanket; and an attachment member 21 attached to one surface of the brick body 10 in which folds 10a are formed, and is installed on an inner surface of an industrial furnace via the attachment member 21, the attachment member 21 including a metal fitting 25 rectangular in a plan view; and a row of a rod body 27 or a plurality of rows of rod bodies 27 extending in a major side direction of the metal fitting 25 and disposed in a minor side direction of the metal fitting 25, the rod body 27 in each row being formed out of one or a plurality of ceramics sintered bodies having a length of 20 mm or more, and a length of the rod body 27 in each row being set to not more than 60% and not less than 100% of a length of a major side of the metal fitting 25. 【課題】従来に比べて経時劣化が抑制され、長期に亘って断熱性を維持することが可能なセラミックスファイバーブロック及びこれを用いた炉内ライニング構造を提供する。【解決手段】シート状のセラミックスファイバーブランケットを葛折り状に折り畳んでなるブロック体10と、折り目部10aが形成されている、ブロック体10の一方の面に装着された取付け用部材21とを備え、取付け用部材21を介して工業炉の内面に設置されるセラミックスファイバーブロック31であって、取付け用部材21は、平面視して矩形状の金具25と、金具25の長辺方向に延在し、金具25の短辺方向に1列又は複数列配設された棒状体27とを備え、各列の棒状体27は、20mm以上の長さを有するセラミックス焼結体1本又は複数本から構成され、各列の棒状体27の長さが金具25の長辺長さの60%以上100%以下とされている。【選択図】図2
