FIRE-EXTINGUISHING NOZZLE COVER
Document Type and Number:
Japanese Patent JP2018065005
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve workability of installation work of a fire-extinguishing nozzle cover.SOLUTION: A fire-extinguishing nozzle cover 1A covers a fire nozzle 103 from a lower side L of a ceiling board 101, the fire-extinguishing nozzle spraying, to the lower side L of the ceiling board 101, fire-extinguishing fluid 104 supplied by a pipe 102 that extends from an upper side H towards the lower side L of the ceiling board 101. A cover part 9 is integrated with a base part 2. When the fire nozzle 103 does not spray the fire-extinguishing fluid 104, the cover part covers the fire nozzle 103 from the lower side L of the ceiling board 101 and, when the fire nozzle 103 sprays the fire-extinguishing fluid 104, opens the fire nozzle 103 relative to the lower side L of the ceiling board 101. The base part 2 is attached from the lower side L of the ceiling board 101 by screws 8 attached to the lower side L of the ceiling board 101, and seals the lower side L of the ceiling board 101 with respect to the upper side H of the ceiling board 101. Consequently, the base part 2 can be installed by work only from the lower side L of the ceiling board 101, and workability of the installation work of the fire-extinguishing nozzle cover 1A is improved.SELECTED DRAWING: Figure 1
