Prepare the ceiling, want to know how to use light steel keel is long, such as a light steel keel is 3 meters long, and my room is 4.8 meters long, that keel is how to pick up to ensure the length of the Can I guarantee strength?
Strength is no problem.
When the keel is lengthened, pay attention to it, do not put the increase into the above or put the following, to stagger. For example, the extension of a root in the top, then it is next to the two long extension in the bottom. But also to consider the same wall of the keel through the heart to a high degree of consistency.
Do not have a special connector ah. Wood workers now have a tool in hand, the two keel lap, in the coincidence of the parts directly with a few pressure tools, you can. Similar to the rivet, but this tool does not pull rivets, it is directly to the two layers of keel out of a small hole, huh, huh. Woodworking all know.
