限に抑えることもできる。According to the fire spread prevention apparatus of the first aspect of the present invention, when the fire signal is output from the fire detector, the non-combustible sheet is released from the case installed between the monitoring sections in the building. Since the fire that occurred on one side of the monitoring section was prevented from spreading to the other side, it is effective to prevent the spread of fire in facilities such as warehouses where shelves are provided to organize and store articles. It can be carried out. In addition, the non-combustible sheet is housed and the fire signal is input to release the non-combustible sheet, so that the cost can be reduced and it is relatively easy to retrofit the warehouse. be able to. Moreover, since it is installed on the ceiling surface, the installation is easy. In addition, it is possible to minimize water damage to articles such as luggage placed in a place other than the place of fire due to fire fighting activities.

消火を行うことができる。According to the fire spread prevention device of the invention of claim 2,
When a fire signal is output from the fire detector, the non-combustible sheet is released, while water is supplied to the sheet winding core with multiple holes so that the non-combustible sheet is wetted through each hole. Therefore, the spread of fire can be prevented more reliably. According to the fire spread prevention apparatus of the third aspect of the present invention, both side walls in the length direction of the sheet winding core of the case can be opened, and the side wall of the case where the fire is generated when a fire signal is output from the fire detector. Since the water is jetted out from each hole of the sheet winding core to be discharged into the hollow on the side where the fire is generated, the fire can be extinguished while minimizing the water loss of articles such as luggage.
