The method of installing inspection ports after decoration is completed

If this is the case,

Several points to note: Firstly, the internal framework of the gypsum board ceiling should be bypassed, and the access hole should be opened to facilitate the entry and exit of equipment accessories. Gypsum boards are easy to cut, but whether it is a wooden or light steel keel, even if it is a non main keel, the strength of the suspended ceiling will be affected after cutting.
Moreover, even if the keel can be cut, it cannot be cut to a large length, and later maintenance still cannot be convenient for movement. Based on the completion of decoration, it is recommended to purchase or rent a wall detector to plan the internal structure of the gypsum board before proceeding with construction.
The second point is the surface treatment of the top of the finished product. After the gypsum board is cut open, the edges of the latex paint or other surface covering materials on the original top collapse, making it difficult to repair, and the inspection opening after cutting must be made in the form of a movable cover. Therefore, it is recommended to buy a finished frame for the inspection port, and fix the frame in the same way as replacing the manhole cover. The original gypsum board should be embedded in the frame, which can basically achieve no repair.
