No. The quality responsibility and warranty obligation of the fire protection system are affected, and the sprinkler head needs to be replaced with a suitable sprinkler head, the sprinkler water supply of the entire partition needs to be stopped, and the pressure strength test and tightness hydrostatic test of the entire partition need to be re-conducted after the change.
If this requires a suspended ceiling, this one needs to be matched with a suspended ceiling.
According to the bottom width and height of the aluminum square ceiling to design, the general specifications of large aluminum square through spacing can be larger, small specifications of the spacing to be smaller. According to the commonly used specifications, the spacing of the aluminum square pass is generally 100mm (the midpoint distance of the two aluminum square passes).
In places with suspended ceilings, the sprinkler heads are arranged under the ceiling, and they can be arranged at a certain distance and equal distance according to the danger level of the building. The sprinkler head is available in a droop type or a ceiling type. In places without suspended ceilings, spray on the sprinkler. >>>More
The place of the sprinkler head is changed to a cross, make an upper sprinkler head, 10 cm away from the floor slab, and then lead a lower sprinkler head to the ceiling.
