The present invention relates to a height adjusting member of the sprinkler head, and more particularly, to the height of the fire pipe and sprinkler head is embedded at the time of slab casting without the aid of a hanger insert or bracket to the height adjusted to the ceiling slab or In case of insert buried construction, the missing part is drilled from the bottom of the ceiling when installing the sprinkler pipe, and the adjustment guide is installed on the insert after inserting the insert. The present invention also relates to a height adjusting member of a sprinkler head which is secondarily adjusted by freely adjusting the coupling degree of the sprinkler head.

Conventional sprinkler equipment (2), which is used for initial fire extinguishing in the event of a fire, has a branch pipe (6) connected to the fire pipe of the ceiling slab (4), as shown in FIG. The guide pipe (8) to which the branch pipe (6) is connected and installed, the hanger bracket (10) to be installed on the ceiling slab (4) so that the guide tube (8) is installed, and the hanger bracket ( 10) comprises a sprinkler head 12 installed in the adjustment guide tube (8) assembled to move.

The adjustment guide tube 8 installed on the hanger bracket 10 is height-adjusted by the height adjusting holes 16 in consideration of the construction of the ceiling finishing material 14. The sprinkler head 12 coupled to the adjustment guide tube 8 is exposed through the hole 18 of the ceiling finish 14. This hole 18 is sealed by a head cover 20 which is coupled to the sprinkler head 12.

Guide rail 22 and the adjustment screw 24 is formed in the adjustment guide tube (8), the guide brackets (26) into which the guide rail (22) is inserted are formed in the hanger bracket (10) Height adjustment port 16 is coupled to the threaded portion 24 is installed.

The conventional adjustment guide tube 8 requires a hanger bracket 10 that is pre-installed with a bolt 28 on the ceiling slab 4, and the guide rail 22 is moved to move the bracket 10. The adjustment guide tube (8) formed was made of cast iron, bronze or brass, and the adjustment screw portion 24 formed with a screw has to be formed long, there was a problem that assembly is inconvenient.
