2.Use an iron expansion bolt to fix the suspension bar on the top, and fix the light steel keel below the suspension bar to be horizontal (if the grid span does not exceed 3 meters, the suspension bar is not needed);
3.Use cement nails to nail the aluminum angle along the horizontal line;
4.Put the aluminum grille on the ground and assemble it completely;
5.Put the assembled grille ceiling on the aluminum angle iron, and the middle position is directly tied to the light steel keel with a thin wire;
6.The construction process of the grille ceiling.
Accurate measurements: keel finishing, surface planing, half-groove lapping, flame retardant coating, clear oil coating, frosted glass installation.
7.Construction points.
The grille skeleton should be made with accurate measurement of the ceiling size.
The keel should be finished, the surface should be planed, the rod should be opened at the interface, the half-groove lap should be opened at the junction of the horizontal and vertical keel, and the flame retardant should be brushed.
1. Construction process:
Boom - elastic ceiling elevation line - brush black paint above the elevation line - install water, electricity and ventilation pipes - install the surrounding mineral wool board ceiling - preliminary installation of metal grille - set the position and height of the ceiling arch - adjust the height of the fire sprinkler head according to the ceiling arch line - equipment debugging - adjust the metal grille according to the arch height - straighten the fire sprinkler head straight - install lamps and lanterns - finely adjust the grid straight and straight. >>>More
First of all, the top of the tent bolt, the grille on the ground to spell, with the wire to hang up, the grille should be spliced on the floor first, the grille to the ceiling of the position to stay on the installation, so that it will be faster, the iron grille and the aluminum grille are divided into the main bone, the main bone is below, the bone is on the top. From the pre-determined level line in the room to the design height of the ceiling, the surface level line of the ceiling surface layer is ejected with a pink line. >>>More
There is no difference in styling. The main difference is the material, the aluminum grille is light and will not rust in an acid-alkali environment, while the iron grille is relatively heavy, and it is easy to rust in an environment with excessive air humidity for a long time. Another difference is the price, the aluminum grille is more expensive, and the iron grille is cheaper.
If there is a suspended ceiling, a ceiling-type sprinkler is used to be located under the ceiling; If there is no suspended ceiling, the splash tray is under the bottom of the roof sheet, depending on the horizontal distance from the beam. A row of sprinklers must be added to the > combustible ceiling, which is generally sprayed up and down. For details, please refer to the "Code for the Design of Automatic Sprinkler Systems", which has 3 relevant provisions and 1 table.
The landlord asked about the spraying of paints; Or the direction of the sprinkler head of the fire sprinkler. >>>More
