Whether the wooden keel skeleton of the suspended ceiling is fixed with expansion bolts or directly

There is no need to use expansion screws.

The ceiling keel system is equipped with a special hoisting system, and the light steel keel used for the ceiling includes a bearing keel, a covered keel, a hanging piece, a pendant, a hanging insert, a bearing keel connector, a covered keel connector, a lifting bar, and the primary and secondary keel is a light steel keel. The aluminum plate is a portal detachable keel system, and each panel can be easily disassembled, assembled and restored. The tubes can be disassembled independently. >>>More

In my personal opinion, this method is inappropriate, although there are people around me who have used it, but I have never used this method. >>>More

In the case of gypsum ceiling, a wooden keel is generally made on the top now, and the gypsum board is nailed to the wooden keel with nails, otherwise how to be stressed.

Look at the size of the wood, the big point doesn't matter, the small point is best fixed vertically, but the current ceiling materials are relatively light, and the problem is not very big!

The wooden keel is more convenient to shape, but it is not fireproof, the light steel keel is not good for modeling, but the fire performance is good, the best is to use the wooden keel where there is a modeling, and the others are good with light steel keel, and the current calcium silicate board, gypsum board, and woodworking board are 1200x2400mm 1220x2440mm This is basically the basic size of the partition board.
