摘要： PROBLEM TO BE SOLVED: To provide a sprinkler piping unit whereby a high-quality sprinkler facility eliminating the fear of water leakage can be constructed easily in a short construction period. SOLUTION: A plurality of flexible synthetic-resin pipes 35, each preset to a predetermined piping length while assuming the layout of sprinkler heads, and having sprinkler heads 34, 34a, 34b connected to their respective ends, have their root ends connected to a plurality of piping connections provided in a header 29 made of a synthetic resin. After the hydraulic test of connections is complete, the plurality of flexible synthetic resin pipes 35 are wound into coil shapes to constitute a sprinkler piping unit SU sized so that it can be easily transported to a construction site.

摘要： PROBLEM TO BE SOLVED: To secure the functions of a sprinkler facility for a multistoried building in the event of a fire by preventing a vertical pipe leading to an alarm valve placed in a pipe space in a fire limit from being melted by heat from outside the pipe space in the event of a fire, although a synthetic-resin pipe that has problems regarding material and fire resistance is used as the vertical pipe. SOLUTION: In the structure of the floor-slab-penetrating part of a vertical pipe in a sprinkler facility for a multistoried building, a sheath pipe 11 made of steel, which has a flange part 11a formed on its outer periphery, is dropped into a through hole 12 formed in a floor slab 10 in a pipe space PS, and the flange part 11a is secured to the upper surface of. the part of the floor slab around the through hole 12. The vertical pipe 3 for the sprinkler facility is made of a synthetic resin and is passed through the sheath pipe 11, and rock wool 14 is packed between the synthetic-resin vertical pipe 3 and the sheath pipe 11. The sheath pipe 11 is closed at its lower end with fireproof putty 15 and at its upper end with mortar 16.

摘要： PROBLEM TO BE SOLVED: To provide a structure for mounting a sprinkler head in an in-dwelling- unit sprinkler facility, allowing the work of laying the sprinkler facility prior to the construction of a ceiling bed, and allowing the level of the sprinkler head to be adjusted after the ceiling bed is complete. SOLUTION: A sprinkler head 7 is connected via a joint 6 to the end of a synthetic resin pipe 5 for a sprinkler facility laid within a ceiling 2, and the joint 6 is attached to a hanging bolt 9 hanging down onto the lower surface of a floor slab 1, in such a way that the vertical position of the joint 6 is freely adjustable. The sprinkler head 7 is projected indoors from the ceiling face.

摘要： PROBLEM TO BE SOLVED: To eliminate the problems found when an iron pipe is used for piping such as the heavy piping weight, poor executability or the like, by applying a synthetic resin pipe as a pipe for a sprinkler equipment installed in a dwelling unit, and arranging the synthetic resin pipes in a ceiling manufactured by finishing a noncombustible backing with a semi-noncombustible material. SOLUTION: In a sprinkler equipment in a dwelling unit in an apartment house, a pipe 5 for the sprinkler equipment to be arranged in the dwelling unit is made of a synthetic resin, and the synthetic resin pipe 5 is arranged in a ceiling 8 manufactured by finishing a noncombustible backing 6A with a semi-noncombustible material 7A. That is, the pipe is arranged in the ceiling 8 on the areas corresponding to the warning ranges (a), (b) of the sprinkler heads 10a, 10b in the ceiling 8 comprising the semi-noncombustible material 7A prepared by adhering a vinyl cloth 7b on a surface of a gypsum board 7a fixed to a ceiling joint of the noncombustible backing 6A with the screws. Whereby the fear that a piping system to the sprinkler heads 10a, 10b are melted by the heat on fire can be prevented, and the function of the sprinkler equipment can be ensured.
