Description

The present invention relates to a sprinkler head positioning device installed on a ceiling or a wall surface.

  The sprinkler head is installed on the ceiling or wall in the building. One end of the sprinkler head main body has a nozzle following the water supply source, and the nozzle is sealed by a valve body. The valve body is supported by a thermal decomposition section disposed on the other end of the main body. When a fire occurs, the thermal decomposition section is decomposed and the valve body is separated from the nozzle and water is discharged from the nozzle. The water discharged from the nozzle collides with a deflector provided on the extension on the outlet side of the nozzle and scatters in all directions to extinguish the fire.

As a conventional sprinkler head, there is an embedded sprinkler head embedded in a ceiling (for example, see Patent Document 1). The embedded sprinkler head is installed with only the lower end portion protruding from the ceiling surface, and the nozzle portion is connected to the piping behind the ceiling.

The embedded sprinkler head (hereinafter referred to as “sprinkler head”) is connected to the pipe before the ceiling board is installed. In recent years, flexible pipes are used for sprinkler heads, and the ceiling board is fixed to the ceiling base material after the sprinkler head is fixedly installed on the ceiling base material.

When the sprinkler head is fixed to the ceiling base material, the amount of protrusion of the sprinkler head from the ceiling lower surface to the indoor side is adjusted. Specifically, the mounting reference line is displayed on the protective cap attached to the sprinkler head, and the position of the sprinkler head is adjusted so that the height of the mounting reference line and the height of the bottom of the ceiling match. Fix it.

However, since the ceiling board is not installed when the sprinkler head is fixed to the ceiling base material, the operator aligns the mounting reference line below the lower surface of the ceiling base material in consideration of the thickness of the ceiling board. Are working. At that time, hold the flexible tube with one hand and hold the ruler with the other hand to measure the distance from the ceiling substrate. Release the ruler when the distance between the mounting reference line and the lower surface of the ceiling base material is given, and operate the fixing bracket to fix the flexible tube to the ceiling base material.

Especially in apartment houses such as condominiums, in order to pay attention to the amount of sprinkler head protruding from the ceiling, the positioning work is carefully performed so that the amount of protrusion of the indoor sprinkler head is uniform. For this reason, since the operator operates the ruler and the fixtures alternately, positioning the sprinkler head is very laborious and time consuming, and the construction site is dim, making it difficult to see the scale on the ruler and spending time on the work. It was necessary.

JP 2009-291359 A
