Description

Technical Field

[0001] The present application belongs to the field of building decoration and renovation, and in particular relates to an ultra-narrow box-type ceiling structure. Background Art

[0002] In the process of building decoration, we often encounter ceilings designed around the room with a width of no more than 200 mm, which are called ultra-narrow box ceilings in the industry. In order not to affect the installation of downlights and spotlights, ultra-narrow box ceilings are usually constructed with the following structure: wooden keels are fixed on the roof and surrounding walls, and then base boards such as blockboard, multi-layer board or European pine board are hung on the wooden keels to make the ceiling base, and the surface of the base board is covered with gypsum board.

[0003] However, the following problems are encountered when using this type of structure: 1. It is difficult to construct according to national standards during the actual construction process, that is, fire-proof and anti-corrosion coatings are applied on the surface of the keel and base board, which poses a safety hazard; 2. The ceiling base made of a mixture of keels and base boards is often deformed and cracked due to climate change and air humidity changes, which not only affects the decoration effect, but also increases the after-sales maintenance cost; 3. It is necessary to allocate additional materials such as base boards, wooden keels, expansion bolts, etc., which not only increases the management difficulty, but also increases the construction cost.
