PURPOSE:To improve fire extinguishing capacity at the time of a fire by using a ceiling plate with non-combustible gas or a powder fire extinguisher filled in a bag body formed of membranes made of plastic or the like. CONSTITUTION:Gas such as carbon dioxide gas is filled into a bag body formed of a vinyl chloride membrane of approximately 0.3mm in thickness on the surface side 2 and side face side 4, and a vinyl chloride membrane of approximately 0.1mm in thickness on the back face side 3 to form a ceiling board 1. This ceiling plate 1 is supported on plural members engaged at specified spaces apart with supporting bars. Gas is jetted out when the ceiling board 1 explodes due to fire to heighten fire extinguishing capacity. |
