I want to make a light steel keel ceiling, but the roof is colored steel tile, and the roof is more than 5 meters high. I just want to hang it to a height of 2.5M m. How to make such a ceiling?

5 cm X 10 cm square iron pipe can be used (the pipe wall thickness is not less than 1.8MM and the room width is not more than 3.5M).

The specific operation method is as follows: after the top elevation position is horizontally installed about 30cm (not less than 20cm) (with a spacing of about 100cm) and fixed, screw the large crane on the square pipe with self-drilling screws according to the spacing position of the main keel. (Note that the big crane is installed upside down (the shape of the big crane needs to be changed, and it needs to be smashed into an inverted 7-shape, and the hole that used to wear the boom is still worn with it. ) at the same time, the distance should be basically the same, so that the main keel is in a straight line; Then install the suspension spring and fix it with nuts (this suspension spring should be 20 cm long). Next, hang a big crane, install the main keel, and adjust the height of the lower end of this suspension spring as usual.

Since you want to make a room that looks like a hotel, you must divide it into small rooms. Now you can do this: first, use light steel keel to make gypsum board wall, 3 meters light steel keel to make it, and 3 meters gypsum board. After building the wall, do as I did above. First, the iron square pipe can be directly fixed on the top surface of the light steel keel wall, and the upper plane of the iron square pipe is connected with 50 pairs of ceiling joists with rivets to prevent it from overturning. The spacing should not exceed1.2m. This size can be divided equally. In this way, you don't need to consider connecting the boom to the roof. If the width of the divided room is less than 3 meters, a 6-meter-long square iron pipe can just hold two rooms.

I think the situation is much simpler than I knew before. If you still can't understand it yourself, I suggest you find a carpenter to read my passage. I believe he can understand.

If there is anything you don't understand, we can continue our discussion. That's what I do.
