Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, and more specifically, to a double-layer ceiling structure. Background Technology

[0002] A suspended ceiling refers to the decoration of the top of a dwelling; simply put, it refers to the decoration of the ceiling and is an important part of interior decoration. With the development of the building decoration industry, the requirements for spatial aesthetics are increasing. Traditional single-layer suspended ceiling systems (such as gypsum board, mineral wool board, etc.) can meet basic functions, but their designs are monotonous and lack a sense of layering, making it difficult to meet the artistic expression needs of high-end public spaces. Although double-layer suspended ceiling structures are gradually appearing in interior decoration, existing traditional double-layer suspended ceiling structures mostly use homogeneous flat materials, making it difficult to achieve the composite aesthetic effect of a sealed base layer and a three-dimensional translucent layer, resulting in poor visual appeal.

[0028] In this embodiment, the double-layer gypsum board 23 is fixedly connected to the secondary keel 22 by self-tapping screws. See also Figure 4 When installing the double-layer gypsum board 23, first fix the upper layer of gypsum board to the secondary keel 22 with self-tapping screws. After the upper layer of gypsum board is installed, fix the lower layer of gypsum board to the secondary keel 22 with self-tapping screws. When installing the gypsum board, the distance between the self-tapping screws should not exceed 200mm. The double-layer gypsum board 23 must be installed with staggered joints; that is, the joints between the upper and lower layers of gypsum board should be staggered by a certain distance. After the double-layer gypsum board 23 is installed, the surface layer is leveled with putty and then sprayed with paint.

[0029] Before installing the gypsum board ceiling layer 2, a second hanger 42 is reserved for connecting the hexagonal metal grid ceiling layer 3.

An opening is provided on the other right-angled side of the L-shaped bracket 421. The lower end of the second hanger 42 passes through the opening on the L-shaped bracket 421 and is locked in place by two nuts. In this embodiment, the dedicated keel 31 is made of a 40mm × 20mm × 2mm rectangular tube, and the one right-angled side of the L-shaped bracket 421 is fixedly connected to the longer side of the dedicated keel 31 by a self-tapping screw. The distance between two adjacent dedicated keels 31 is no greater than 1200mm.

[0031] Furthermore, to facilitate the connection between the dedicated keel 31 and the hexagonal metal grille 32, a U-shaped connector 33 is fixedly connected to the bottom of the dedicated keel 31, and a lifting lug 321 is provided on the hexagonal metal grille 32. The hexagonal metal grille 32 is fixedly connected to the U-shaped connector 33 through the lifting lug 321. See details. Figure 5 The bottom of the dedicated keel 31 is fixedly connected to an inverted U-shaped connector 33 by self-tapping screws, i.e., the opening of the U-shaped connector 33 faces downwards. The top of the hexagonal metal grille 32 is provided with a lifting lug 321. When the hexagonal metal grille 32 is connected to the dedicated keel 31, the lifting lug 321 on the hexagonal metal grille 32 is inserted into the inverted U-shaped connector 33, and the lifting lug 321 and the U-shaped connector 33 are connected and fixed by self-tapping screws. Adjacent hexagonal metal grilles 32 are connected by self-tapping screws so that multiple hexagonal metal grilles 32 are assembled into a single structure. See also... Figure 6 In this embodiment, two lifting lugs 321 are respectively provided on each of the six sides of the hexagonal metal grille 32. A portion of the hexagonal metal grille 32's sides are located directly below the dedicated keel 31 and can be connected and fixed to the U-shaped connector 33 at the bottom of the dedicated keel 31 via the lifting lugs 321. For the other portion of the hexagonal metal grille 32 whose sides are not directly below the dedicated keel 31, they are connected and fixed to the corresponding lifting lugs 321 on the sides of adjacent hexagonal metal grille 32 using self-tapping screws. In other alternative embodiments, the number of dedicated keels 31 can be increased so that all hexagonal metal grilles 32 are directly connected and fixed to the dedicated keel 31.

[0032] In summary, the double-layer ceiling structure provided by this utility model has a simple connection structure, is easy to construct, and improves the flexibility of installation; by hanging a hexagonal metal grid ceiling layer below the gypsum board ceiling layer, it increases the sense of layering of the ceiling design and improves the three-dimensional effect and aesthetic appeal of the space.
