ã€China Aluminum Network】Aluminum grille is one of the ceiling materials produced in recent years. The aluminum grille has an open field of view, ventilation, ventilation, neat and neat lines, a clear hierarchy, reflects the simple and modern style, installation and removal Simple and convenient, it has become the main product of the decorative market in recent years. The aluminum grille can be mainly divided into grooved aluminum grille and flat aluminum grille.
Construction process 1, determine a good height, use the high level of the ink fountain on the wall 2, use iron expansion bolts to fix the ribs on the top, and fix the light steel keel under the ribs to maintain the level (if the grille span does not exceed 3 meters No need for lifting
3, using cement nails to nail the aluminum corner line along the horizontal line 4, put the aluminum grille on the ground to complete the group 5, the group put together a good grille ceiling on the aluminum angle iron, the middle position with a thin wire directly in the Light steel keel.
(1) The bouncing line water level meter will copy the horizontal point on each wall (pillar) corner in the room (if the wall is long, the center should also appropriately copy a few points), the pop-up level (the level line is generally 500? ) From the leveling line to the ceiling design height, use the powder line to pop the level line along the wall (column), which is the lower skin line of the ceiling grid. At the same time, according to the ceiling plan, the main keel is ejected from the concrete ceiling. The main keel should be divided from the center of the ceiling to two sides, with a large distance of 1000?, and the fixed point of the boom is marked. The fixed point spacing of the boom is 900? to 1,000?. If the beam and pipe fixing points are greater than the design and specification requirements, the fixing point of the boom should be increased.
(2) Fix the hanging rod by using expansion bolts. Can use Ñ„6 boom. Hangers can be made of cold drawn steel bars and coiled steel bars, but the use of coiled steel bars should be mechanically straightened. One end of the boom is welded to the L30*30*3 corner. (The hole diameter of the corner should be determined according to the diameter of the boom and the expansion bolt.) The other end can use the tapping to pull out the Screw which is bigger than 100?, or you can buy the finished wire. Rod welding. The prepared boom shall be treated with rust prevention. The boom shall be fixed on the floor with expansion bolts, and shall be drilled with an impact electric hammer. The hole diameter shall be slightly larger than the diameter of the expansion bolt.
(3) Light steel keel installation Light steel keel should be hung on the boom (If the ceiling is lower, this process can be omitted and the next process can be performed directly). Generally used 38 light steel keel, spacing 900 ~ ~ 1000?. The light steel keel shall be installed parallel to the room and shall be arched at the same time. The arching height shall be 1/200 to 1/300 of the room span. The cantilever section of the light steel keel should not be greater than 300?, otherwise booms should be added. The length of the main keel should be butt-jointed, and the butt joints of adjacent keels should be staggered. After the light steel keel is hung, it should be basically leveled.
For suspended ceilings with a span greater than 15m, a large keel must be added every 15m to the main keel, and the vertical main keel must be welded firmly.
(4) Spring plate installation: Connect with the light steel keel with a suspender (If the ceiling is low, install the spring plate directly on the suspender to omit this process), the distance is between 900 and 1000?, and then the spring piece is stuck on the hanger. On the pole.
(5) Assembly of main and auxiliary grids The main and sub-grids of the grid are pre-assembled according to the design drawings.
(6) Grille installation Place the pre-installed grille ceiling in the main bone hole with a hook and lift it. After connecting the entire grille ceiling, adjust it to the level.
