Claims5
A method of installing pipes for sprinkler head mounting which comprises:
- connecting a plurality of auxiliary water-supply pipes to a fire-water main supply pipe with spacing from each other;
- connecting a plurality of joints to said auxiliary water-supply pipes with spacing from each other through an inlet port formed substantially centrally of each of said joints, each of said joints further having at least four outlet ports formed radially and horizontally on an outer periphery of said joints and extending in at least four different radial directions;
- connecting a sprinkler head to each of said four outlet ports of each said plurality of joints through a flexible joint pipe in such a manner as to radially dispose said sprinkler heads at predetermined positions, using flexibility of said flexible joint pipe.
