7. 1.6 Except for the sprinklers on the ceiling and the sprinklers set under the ceiling, the distance between the splash plate of the sprinklers with vertical drooping standard coverage area and the sprinklers with expanded coverage area and the roof shall be 75mm~ 150mm, and shall meet the following requirements:
? 1 when the nozzle is arranged on the plane below the bottom of the beam or other obstacles, the distance between the splash plate and the top plate should not be greater than 300mm, and the vertical distance between the splash plate and the bottom of the beam and other obstacles should be 25 mm ~100 mm. ..
? 2 When arranging sprinklers between beams, the distance between sprinklers and beams shall comply with the provisions in Article 7.2. 1 of this specification. When there are difficulties, the distance between the splash plate and the roof should not be greater than 550 mm. When the distance between the splash plate and the roof reaches 550 mm, the nozzle should be added below the bottom of the beam if it still cannot meet the provisions of Article 7.2. 1 of this specification.
? 3 For the sprinklers below the multi-ribbed beam slab, the vertical distance between the splash plate and the bottom of the multi-ribbed beam slab should be 25mm~ 100mm.
? 4 Sprinklers between beams without suspended ceiling can be arranged at different intervals, but the water spraying intensity should still meet the requirements in Tables 5.0. 1, 5.0.2 and 5.0.4- 1~ 5.0.4-5 of this specification.
7. 1.7 Except for the ceiling sprinklers and sprinklers arranged under the ceiling, the distance between the splash plate of vertical sprinklers, drooping sprinklers, early-suppression rapid response sprinklers, special sprinklers and household sprinklers and the roof shall comply with the provisions in Table 7. 1.7.
7. 1.8 There should be nozzles above the passages of libraries, archives, shopping malls and warehouses. The horizontal distance between the nozzle and the protected object shall not be less than 0.30m, and the minimum vertical distance between the nozzle splash plate and the protected object shall not be less than that specified in Table 7. 1. 8.
7. 1.9 The built-in sprinklers in the shelf should be staggered from the sprinklers under the roof, and the distance between the splash tray and the upper deck should comply with Article 7. 1.6 of this specification, and the vertical distance between the splash tray and the top surface of the lower storage should not be less than150 mm.
7. 1. 13 In the place where the grid and grid permeable ceiling are installed, when the permeable area accounts for more than 70% of the total area of the ceiling, the nozzle should be set above the ceiling and meet the following requirements:
? 1 The clear width of the opening of the transparent ceiling should not be less than 10mm, and the thickness of the opening should not be greater than the minimum width of the opening;
? 2 The distance between the nozzles and the distance between the splash plate and the upper surface of the ceiling shall comply with the provisions of 7. 1. 13.
7. 1. 14 When the roof or ceiling is inclined, the arrangement of the nozzles shall meet the following requirements:
1 The nozzles shall be perpendicular to the inclined plane, and the nozzle spacing shall be determined according to the inclined plane distance;
2 A row of sprinklers should be set at the ridge of sloping roof. When the roof slope is not less than 1/3, the vertical distance from the sprinkler splash plate to the roof should not be greater than 800mm；; When the roof slope is less than 1/3, the vertical distance between the nozzle splash plate and the roof should not be greater than 600 mm
7. 1. 15 The distance between the splash plate of the side wall sprinkler and the top plate and the back wall shall comply with the provisions in Table 7. 1. 15.
7. 1. 16 The nozzle arrangement of the fire separation water curtain shall ensure that the width of the water curtain is not less than 6m. When a water curtain nozzle is used,
