The problem of sprinkler head setting at the grille ceiling is easy to ignore
-
issue
The hollowing rate of the place with the grille ceiling is greater than 70%, and the sprinkler head is arranged below the ceiling.

Regulatory basis
Article 7.1.13 of the Code for the Design of Automatic Sprinkler Systems (GB50084-2017).
- Reference:
When the construction is carried out to the grille ceiling area, the construction unit should maintain communication with the design unit in a timely manner to clarify the way of setting up the sprinkler in the construction; the supervision unit should increase the supervision in the construction process, and the responsible entity should be required to rectify the area where the sprinkler head is not set up in accordance with the requirements of the specification.
Therefore, the following reference practices can be adopted:
1. When constructing to the grille ceiling area, it should be communicated with the design unit in time to clarify the sprinkler setting method; setting method: (1) for the grille ceiling where the proportion of the permeable area to the total area of the ceiling is greater than 70%, the net width of the permeable ceiling opening should not be less than 10mm, and the thickness of the opening should not be greater than the minimum width of the opening, the sprinkler should be set above the ceiling, and the spacing of the sprinkler head and the distance between the splash disc and the ceiling should be conformed;
2. For the grille ceiling that does not meet the proportion of the permeable area to the total area of the ceiling is greater than 70%, the net width of the permeable ceiling opening should not be less than 10mm, and the thickness of the opening should not be greater than the minimum width of the opening.
