SPRINKLER HEAD RING

摘要

The present disclosure relates to a sprinkler head ring to hold the head of a sprinkler used for a sprinkler in fire extinguishing facility. The sprinkler head ring provided in this disclosure is to settle a problem that a sprinkler head bounces to the ceiling material due to reaction force created when fire extinguishing water is opened and injected from the sprinkler head at an outbreak of fire. The sprinkler head ring having a function to fix a sprinkler head includes two semicircular-shape sprinkler head rings which are two halves of a circular-band shape sprinkler head ring with protruded insertion portions at the end of lower edge portions of the ring so that the protruded insertion portions prevent the sprinkler head from bouncing up due to the reaction force created by opening of fire extinguishing water, and which has a protruded insertion portion and a recessed insertion portion so as to engage a protruded insertion portion with a recessed insertion portion before using a pin to fix.
