装修的施工工艺及其具体材料和主材（The construction technology and specific materials and decoration materials） The construction technology and specific materials and decoration materials Construction technology of grid ceiling 1. construction process: The bomb - wire - line standard ceiling above elevation brush black paint - Installation of water and electricity, ventilation pipe installation - circle - metal grille ceiling installation of mineral wool board - ceiling arching position and height -- at springline ceiling sprinkler head height adjustment, equipment debugging -- height adjustment metal grille - straightening fire the spray head straight - mounted luminaires -- fine grille straight arch at. 2. ceiling plane position find rules: because various shopping malls things 120m long, north-south width 34.7m, column spacing 8.0m*8.0m, the area is larger, so must deal with a metal grid ceiling, mineral wool board, between the ceiling and wall, column vertical or parallel relationship, which should be related to the measuring axis to column wall facade, and according to the datum line pull to find rules so as to ensure the wall plastering, both cylindrical and parallel to the axis, and two adjacent faces perpendicular to each other. This is used as the datum plane of the ceiling plane. 3. grille ceiling arch and arch height: the vertical size should not be too long because of Engineering arch, the arch should be in the short north-south direction to the arch height by about 1 / 200 8m zhuju. The plane position and not the 4. grid fire sprinkler overlap, and should be two directions should be straight, this can be in the upper end of the vertical tube is made of fire sprinkler is greater than 900 of the pedal bend to adjust spray head position. 5.: check the hole indwelling equipment for various pipelines in the grille ceiling is provided with an adjustable valve, check the hole shall be retained in the corresponding position, and check the hole position and not in this aspect, ca
