Light steel keel ceiling installation detailed process
Simpler. Expand the screw to fit and connect the hanging bars. 2, arranged the main keel, 3, deputy keel. Finish
Install the side keel:
The installation of the edge keel should be designed according to the design requirements of the elastic line, along the horizontal column on the pillars of the L-shaped galvanized steel bar with self-tapping screws fixed on the embedded wood bricks, such as concrete studs, The spacing of the nails should be less than the distance between the keel.
Fixed hanging parts:
Fix the hanging rod with expansion bolts. With the impact hammer in the top plate drilling, the installation of expansion bolts, one end of the boom with L30 × 30 × 3 angle welding, the other end with the threaded rod welding, making a good boom should be anti-rust treatment, not on the ceiling , The length of the boom is less than 1000mm, can be used when the hanging bar is greater than 1000mm, should use the hanging of the crane, the ceiling, the boom length is less than 1000mm, can be used when the hanging bar is greater than 1000mm when hanging, Should pay attention to hanging should be straight and have sufficient bearing capacity, when the bar need to take a long time, must be lap welding, welding to be uniform and full, ceiling lamps, tuyere and repair mouth, etc. should be added boom.
Light steel keel:
With the level of the room in each corner of the wall to copy the level of the point, pop the horizontal line, with the amount of water to the ceiling design height plus a layer of thickness, with powder line along the column pop-up line, that is, Down line. At the same time, according to the ceiling plan in the concrete roof pops up the position of the main keel, the main keel should be from the center of the ceiling to the two points, the maximum spacing of 1000mm, and marked the boom of the keel should be from the ceiling to the two points, and marked the fixed point of the boom, The fixed point spacing of the boom is 900-1000mm. If the fixed point of the beam and pipe is larger than the design and procedure requirements, the fixed point of the boom should be increased.
