Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a ceiling grid structure. Background Art

[0002] Ceiling grilles are a commonly used material or component in the field of interior decoration. They usually refer to grid-like plates made of metal or wood used for ceiling decoration. These grilles can be processed into different shapes, sizes and patterns according to design requirements. They can not only cover pipelines and provide ventilation, but also increase the layering and aesthetics of the ceiling. In the interior decoration of homes, offices or other buildings, ceiling grilles can not only hide pipeline equipment such as air conditioners and lighting, but also have the effect of heat insulation and sound insulation. In addition, the material and design of ceiling grilles can also reflect the overall style and decorative taste of the building to a certain extent, so they are widely used in interior design.

[0003] The installation position of ceiling grilles is usually at the top of the room. They can be installed on the roof truss or the original ceiling structure through a suspension system. Most indoor and outdoor ceiling grilles are now composed of multiple grille tubes and frames. However, this type of ceiling grille needs to be assembled into a single unit in the factory and then transported to the construction site for positioning and installation. The processing process is complicated, and during on-site installation, it is necessary to position the specific position of each grille assembly to ensure that the spacing between adjacent ceiling grilles is consistent, which is time-consuming and labor-intensive. At the same time, the frames of such ceiling grilles are mostly exposed, and the hollow positions between the ceiling grilles make the rear structure of the ceiling grille visible, so that after the installation is completed, the ornamental value of the ceiling is destroyed by the frame and visible position, affecting the aesthetics, so that the frame and visible parts need to be decorated separately, wasting resources, or not decorated, affecting the actual appearance.

[0004] Therefore, it is necessary to design a ceiling grid structure which is small in size, easy to transport, can be installed in a self-positioning manner, has high ornamental value after installation, and does not require additional decoration. Utility Model Content

[0005] The utility model provides a ceiling grid structure which is small in size, easy to transport, can be installed in a self-positioning manner, and has a high ornamental value after installation, and does not require additional decoration. The ceiling can be obtained by splicing several ceiling grid structures, aiming to solve one or more of the above-mentioned problems and other potential problems.

[0006] The utility model provides a ceiling grille structure, characterized in that it comprises: a grille main board provided with a decorative surface and a connecting surface, a ceiling decorative part arranged on the decorative surface of the grille main board, a keel fixing part arranged at a fixed end of the connecting surface for connecting with a keel, and a main board overlapping part arranged at an overlapping end of the connecting surface for connecting adjacent ceiling grille structures.

[0007] In the embodiment, a keel fixing portion and a mainboard overlapping portion are respectively provided at both ends of the grille mainboard connecting surface, wherein the keel fixing portion is used to directly contact the keel, and the keel fixing portion is fixedly connected to the keel by means of screws, bolts, welding, etc., thereby preliminarily fixing the fixed end of the grille mainboard connecting surface.

[0008] Furthermore, a mainboard overlapping portion is provided at the overlapping end of the grille mainboard connecting surface, and the mainboard overlapping portion is connected to the keel fixing portion of the adjacent ceiling grille structure. The overlapping end of the grille mainboard connecting surface is fixed by clamping the keel fixing portion with the mainboard overlapping portion, thereby completing the fixation of the ceiling grille structure.

[0009] In the embodiment, the structure of the keel fixing part and the main board overlapping part is set so that they can fit tightly together, and the keel fixing part of the grille main board is used to bear the weight of the overlapping ends of the adjacent grille main boards, so that when the ceiling grille structure is installed, only the fixing work of the keel fixing part and the keel needs to be completed. The installation efficiency is high, and the disassembly and assembly are convenient. There is no need to measure the installation position of each ceiling grille structure. After the installation position of the first ceiling grille structure is selected, the remaining ceiling grille structures are overlapped and installed in turn, and can be installed by self-positioning. The spacing between adjacent ceiling grille structures can be ensured to be constant without measurement.

[0010] Furthermore, after installation, only the decorative surface of the grid main board and the ceiling decorative part of the ceiling grid structure are exposed, so that the obtained ceiling has strong ornamental value and high aesthetics.

[0011] In some embodiments, the keel fixing portion includes a connecting side panel arranged on the fixed end of the connecting surface, a positioning side panel overlapping the main board overlapping portion of the adjacent ceiling grid structure, and a fixed main board respectively connected to the connecting side panel and the positioning side panel, and the connecting surface and the keel fixing portion surround to form an overlapping groove for cooperating and fixing the main board overlapping portion of the adjacent ceiling grid structure.

[0012] In the embodiment, connecting side panels, positioning side panels, and fixed main boards are used to cooperate with the connecting surfaces to form overlapping grooves, which provide space for the overlapping parts of the main boards to move during the overlapping operation, increase the contact area between the overlapping parts of the main boards and the keel fixing parts, reduce the gap between adjacent grille main boards, make the splicing of the ceiling grille structure more secure, and ensure the integrity and aesthetics of the ceiling.

[0013] In some embodiments, the mainboard overlap portion includes an overlap plate arranged at the overlap end of the connection surface and a positioning plate arranged at the overlap end of the connection surface parallel to the overlap plate for cooperating and connecting with a positioning side plate of an adjacent ceiling grid structure.

[0014] In the embodiment, the splicing of two ceiling grilles is completed by overlapping the lap plate on the fixed end of the connecting surface of the adjacent grille main board and making the positioning plate abut against the positioning side plate of the adjacent ceiling grille structure. Moreover, since the positioning side plate abuts against the positioning plate of the adjacent ceiling grille structure and the lap plate abuts against the fixed end of the connecting surface of the adjacent grille main board, it can be ensured that the two ceiling grilles are spliced ​​tightly and are not easy to fall off.

[0015] In some embodiments, a gasket groove for placing a buffer gasket is provided on the fixed main board.

[0016] Furthermore, since the volume of the ceiling grid structure and the keel will change slightly due to temperature, if the two are directly rigidly connected, they may be broken or damaged due to volume expansion. Therefore, a gasket groove is provided on the fixed main board, which can be used to place flexible gaskets to provide a buffer for the connection between the ceiling grid structure and the keel.

[0017] In some embodiments, the depth of the gasket groove is 0.1 to 0.3 times the thickness of the fixed mainboard.

[0018] In the embodiment, the depth of the gasket groove is controlled to prevent the rigidity of the fixed main board from being reduced due to the provision of the gasket groove, thereby ensuring the rigidity of the fixed main board so that it can bear the weight of the ceiling grid structure.

[0019] In some embodiments, friction lines are provided on the overlapping surfaces of the overlapping plate and the overlapping groove, and friction lines are provided on the overlapping surfaces of the overlapping groove and the overlapping plate.

[0020] In some embodiments, friction lines are provided on the connecting surfaces between the positioning plate and the positioning side plate, and friction lines are provided on the connecting surfaces between the positioning side plate and the positioning plate.

[0021] In some embodiments, the friction pattern is a dot pattern or a wave pattern.

[0022] In the embodiment, friction patterns are provided on the overlapping surfaces of the overlapping plates and the overlapping grooves, the overlapping surfaces of the overlapping grooves and the overlapping plates, the connecting surfaces of the positioning plates and the positioning side plates, and the connecting surfaces of the positioning side plates and the positioning plates, so as to increase the friction when adjacent ceiling grid structures are connected, reduce the connection gap, and make the connection of the ceiling grid more stable.

[0023] In some embodiments, the ceiling decoration part is a hollow tubular structure.

[0024] In the embodiment, the ceiling decoration part is a hollow tubular structure to reduce the mass of the ceiling decoration part, and the hollow tubular structure is convenient for ventilation, which can prevent the interior of the ceiling from being damp after installation.

[0025] By implementing the above technical solution, the utility model has the following advantages:
