Description

Technical Field

[0001] The invention belongs to the technical field of building decoration, in particular to a light steel keel thin plate coating and aluminum alloy grille twist snap-on type combined ceiling system. Background Art

[0002] With the development of technology in the field of construction, architectural decoration has shown diversified and personalized characteristics. Some designers have designed a composite ceiling: there is a light steel keel thin plate (paper-faced gypsum board, calcium silicate board) painted ceiling, and a laminated aluminum alloy grille is set just below it. However, it is quite difficult to install the aluminum alloy grille only from the bottom of the light steel keel thin plate painted ceiling. There are two reasons: First, the light steel keel thin plate painted ceiling will cover the large space of the indoor floor into two smaller opaque spaces above and below. Therefore, it is difficult to take care of the light steel keel thin plate painted ceiling and the aluminum alloy grille ceiling below it: the conventional single aluminum alloy grille ceiling is installed through the fishbone keel, and the overall visual effect is transparent. The fishbone keel is also exposed in the gap between the grilles. However, for the combination ceiling of light steel keel thin plate coating and aluminum alloy grille, the aluminum alloy grille cannot be installed through the fishbone keel, because the gap between the grilles is the light steel keel thin plate coating ceiling, and the keel must not be exposed. In this case, if the light steel keel thin plate coating ceiling is installed first, how will the subsequent aluminum alloy grille ceiling be fixed to the top, and how will the top fix the position and elevation of the aluminum alloy grille below be controlled accurately? If the aluminum alloy grille ceiling is installed at the same time as the light steel keel thin plate ceiling, the above defects are still difficult to control. In addition, there must be enough space between the suspended ceiling and the structural floor above it for people to operate and work, otherwise it cannot be implemented; secondly, there will obviously be problems with the paint on the light steel keel thin plate suspended ceiling if it is applied before the installation of the aluminum alloy grille below, because the installation of the aluminum alloy grille will inevitably contaminate the already applied paint; and there will still be problems with applying the paint after the aluminum alloy grille below it is installed, because the spacing between the aluminum alloy grilles is small, that is, when applying the paint, the aluminum alloy grille will become an obstacle and affect the painting, making it difficult to operate, and it is also easy to contaminate the aluminum alloy grille. Summary of the invention

[0003] In view of the above problems, the purpose of the present invention is to provide a light steel keel thin plate painted and aluminum alloy grille twist snap-on combined ceiling system, which can simultaneously take into account the installation of light steel keel thin plate painted ceiling and aluminum alloy grille ceiling without affecting each other.

[0021] The structure of the present invention and the technical effects to be achieved will be described below with specific embodiments in combination with the accompanying drawings. However, the selected embodiments are only used for illustration and explanation and are not intended to limit the scope of the present invention.

[0022] like Figure 1-Figure 3 As shown, the present invention provides a light steel keel thin plate coating and aluminum alloy grille twist snap-on combined ceiling system, comprising a light steel keel thin plate ceiling 1 and an aluminum alloy grille ceiling 2.

[0023] The light steel keel sheet ceiling 1 includes a plurality of horizontal main keels 11 and secondary keels 12, and a ceiling board 13. The top of the main keel 11 is fixedly connected to the top of the building through a connector, and the secondary keel 12 is perpendicular to the main keel 11 and fixed to the bottom surface of the main keel 11. The ceiling board 13 is fixedly connected to the bottom surface of each secondary keel 12. Specifically, Figure 3 As shown, the secondary keel 12 has a U-shaped cross section, and an inwardly-facing recessed portion 121 is provided at the bottom, and L-shaped end caps 122 extending inwardly are provided at both ends of the top. Preferably, the ceiling board 13 includes a silicate board base layer 131 and a calcium silicate board surface layer 132 (mainly considering its strong grip on the fixing screws), and the bottom of the calcium silicate board surface layer 132 is provided with paint.

[0024] The aluminum alloy grid ceiling 2 includes a plurality of torsion hangers 21 and grid tubes 22. Figure 4-Figure 6 As shown, the torsion hanger 21 includes a rectangular top plate 211 and a bottom plate 212. A connecting hole 213 with a trumpet-shaped cross-section is provided in the middle of the top plate 211, and the diameter of the top of the connecting hole 213 is larger than the diameter of the bottom; a connecting rod 214 is extended upward from the middle of the bottom plate 212, and a rotating head 2141 corresponding to the shape of the connecting hole 213 is provided on the top of the connecting rod 214. The rotating head 2141 is located in the connecting hole 213, so that the connecting rod 214 can rotate. The connecting rod 214 is sleeved with a torsion spring 215, the top end of which is inserted into the upper positioning hole 2111 on the top plate 211, and the bottom end of which is inserted into the lower positioning hole 2121 on the bottom plate 212, so that the top plate 211 and the bottom plate 212 are normally kept perpendicular to each other; the top plate 211 is provided with a mounting hole 2112, and is fixedly connected to the ceiling plate 13 through the fixing screws 23 in the mounting hole 2112, so that the top plate 211 is tightly attached to the bottom surface of the ceiling plate 13. When there is a position of the secondary keel 12 on the top of the torsion hanger 21, the secondary keel 12 is fixedly connected to the corresponding fixing screws 23.

[0025] like Figure 7 As shown, the cross section of the grille tube 22 is U-shaped, and both ends of the top are provided with a limiting portion 221 with a rectangular cross section, and the outer wall of the grille tube 22 is flush with the limiting portion 221. The bottom ends of the two limiting portions 221 are respectively located on the top surfaces of the two sides of the bottom plate 212, so that the top surfaces of the two limiting portions 221 are in close contact with the bottom surface of the ceiling board 13. Specifically, the horizontal distance between the two limiting portions 221 is greater than the width of the bottom plate 212 and the top plate 211 (so that the top plate 211 and the bottom plate 212 can be inserted between the two limiting portions 221), and is smaller than the length of the bottom plate 212 (so that the bottom plate 212 can support the two limiting portions 221), and the horizontal distance between the inner walls of the grille tube 22 is greater than the length of the bottom plate 212 (so that the bottom plate 212 can rotate in the grille tube 22).

[0026] like Figure 8As shown, during the installation of the present invention, the light steel keel thin plate ceiling 1 is first installed according to the traditional method. After the ceiling board 13 is puttyed and painted, the top plate 211 of the torsion hanger 21 is fixedly connected to the ceiling board 13 by the fixing screws 23, and the aluminum alloy grid tube 22 is hung on the above-mentioned torsion hanger 21 by pushing up: first rotate the bottom plate 212 at the lower end of the torsion hanger 21 by 90° without letting go, and at the same time push the grid tube 22 vertically upward; when the bottom plate 212 of the torsion hanger 21 enters the neck cavity of the grid tube 22, let go and continue to push the grid tube 22 upward; when the grid tube 22 moves vertically upward to contact with the ceiling board 13, the bottom plate 212 at the lower end of the torsion hanger 21 rebounds and rotates 90° under the energy storage action of the torsion spring 215, and the bottom plate 212 of the torsion hanger 21 will hook the bottom surface of the limiting portion 221 on the upper part of the grid tube 22 to hang it firmly.

[0027] The light steel keel thin plate coating and aluminum alloy grille twist snap-on combined ceiling system of the present invention can simultaneously take into account the installation of light steel keel thin plate coating ceiling and aluminum alloy grille ceiling without affecting each other, thus solving the long-standing technical problem in the industry.

[0028] The present invention is defined by the claims, but based on this, a person skilled in the art may make various obvious changes or modifications, which should be within the main spirit and scope of protection of the present invention.
