Play the line, the installation of the boom; install the main keel, the installation of the keel, the arch from the leveling, and the installation of aluminum ceiling.
2 construction method
(1) according to the drawing first in wall, column pop-up roof level elevation of ink, the roof draw ceiling layout, determine the boom position and original reservation boom welding, such as the original location of the hanger is inconsistent with or without reservation hanger, the M8 expansion bolt to fix the roof, boom using Phi 8 steel processing.
(2) keel installed in accordance with the ceiling elevation, after the basic positioning regulating suspension leveling hypodermis (pay attention to the amount of arch); to determine the specifications of the plate medium and small keel position must be medium and small keel and keel bottom surfaces are tightly, the installation of vertical hanging used clamp tight, and prevent the loose tight a.
(3) The main keel spacing is 1000mm, keel joint to stagger; direction of the suspender is also to be staggered, to avoid the main keel leans to one side. Hanger bolt adjustment, ensure a camber, depending on room size arching 5-20mm, room to the short 1 / 200, after treats the roughness of the water regulating them one by one to tighten the nut, hole position should be reinforced keel.
(4) in the construction process of attention between the various types of work with until the completion of the ceiling of the outlet, lighting, fire pipelines construction, and through various tests before mounting panel.
(5) aluminum panel installation: pay attention to the aluminum plate surface color, must conform to the requirements of the design code, approved the geometric size of the aluminum plate, deviation from plus or minus 1 mm, installation attention butt size, after the installation gently tear the surface protective film.
