There are many ways to open the ceiling of gypsum board. After all, gypsum board is not that hard.
First of all, you draw a suitable circle, which is not the point. First, you must know the opening size of the downlight, and then you can use two ordinary nails. Nail the thread together. The distance between two nails is half the size of the opening. Then, determine the center position of the opening. Nail in this central position, and then turn the nail that is not at the center of the circle to ensure that the line is not bent, and earn more laps so that the gypsum board will break. You can also find a small saw blade, break it from the center, insert the saw blade into the gypsum board and saw it along the circle. It's easy, right? You can also think of other methods.
In addition, you should pay attention to 1. The hole in the gypsum board ceiling must be excavated according to the diameter of the downlight. If it is too big or too small, it will affect the use and appearance; 2. The position of the opening of gypsum board ceiling must be located according to the position of the design plane, that is, the position of the cable in the lampshade. The channel that does not move will lead to insufficient light lines in the later period and cannot be connected to the downlight. 3. When preparing wiring after opening the gypsum board ceiling, turn off the main switch of the downlight line in the house to avoid the danger of electric shock.
there will be a keel on the ceiling. The overhead ceiling lamp is not heavy. If the installation is relatively light, you can choose to use self-tapping screws to fix directly. If it is a little heavy, you should open a small hole (ceiling light can block it), look inside the keel and fix it on the keel with self-tapping screws.
if the area permits, you can open a hole in the top and add a piece of wood in the light steel keel to fix the lamp. It can also be fixed with expansion bolts and cables.
according to national regulations, lamps and equipment exceeding 3kg must have their own independent supports, and they cannot be fixed on the roof slab or roof keel. Your ceiling lamp should be 15 kilograms. The ordinary lightweight toughened gypsum ceiling with keel does not support this kind of lamp. You must use steel bars as hangers to pass through and fix them directly to the top plate. Otherwise, the lamp cannot be fixed. Not very reliable.
