CONNECTION STRUCTURE OF FIREPROOF PANEL

摘要

PROBLEM TO BE SOLVED: To construct a fireproof wall which facilitates production of a fireproof panel and which is excellent in fireproof performance. SOLUTION: Fireproof panels having a sandwich structure in which a foam plastic 1 is sandwiched between a surface metallic plate 2 and a rear face metallic plate 3, are stacked up to construct the fireproof wall. A mounting recess is partitioned by an upper side step 7d formed at the upper part of the rear face metallic plate 3 of a lower stage fireproof pane Pd and a lower side step 7u formed at the lower part of the rear face metallic plate 3 of an upper stage fireproof panel Pu and a noncombustible hard material 8 is mounted in the recess. A noncombustible hard material 8 reinforced by a metallic casing material 9 can be also used as the noncombustible hard material 8. The recess can be formed in a dovetail groove.
