Branch pipes 8 extending from the main pipe 7 are passed through side walls 9 and the ceiling of the building H, and extend to sprinkler head mounting openings 10 formed in advance. The branch pipes 8 and sprinkler heads 12 are connected and fixed at the sprinkler head mounting openings 10. Preferably, the main pipe is installed at a ceiling position of the outer circumference of the building H. More preferably, a part of each branch pipe 8 is made of a flexible pipe 11.
