Description

Technical Field

[0001] This utility model belongs to the field of prefabricated ceiling technology, and in particular relates to a prefabricated ceiling component. Background Technology

[0002] Prefabricated ceilings are a modern building roof decoration system based on industrialized production concepts. Its core feature lies in breaking down the traditional on-site ceiling structure into prefabricated standardized modules and components. These modules undergo precise processing and quality control in the factory before being transported to the construction site for rapid assembly and installation. The system typically encompasses functional modules such as the keel frame, decorative panels, lighting, ventilation, fire protection, and acoustics, achieving integrated functionality through standardized connection processes.

[0003] Traditional suspended island ceilings typically involve independently suspending metal frames around the edges. This method is complex to construct and requires connecting the edges with suspension rods, which results in the suspension rods being visible from the sides, which is not aesthetically pleasing.

[0004] Another type of prefabricated corridor system involves a complex upper keel structure. Traditional corridor ceilings require drilling holes in the ceiling to install threaded hangers, which are then connected to C-shaped light steel main keels via hangers. The main keels are then connected to painted keels via inverted T-joints. This installation method has limitations in certain situations, such as in old renovation projects or new projects where there are too many ceiling pipes and it is difficult to find hanger points. Therefore, its flexibility is poor. To address the aforementioned issues, this application proposes a prefabricated ceiling assembly. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated ceiling component that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a prefabricated ceiling component, including edge keel and main keel. The edge keel and main keel, as well as adjacent main keels, are connected by secondary keels. The main keel is provided with a sliding strip, and the edge keel is provided with a sliding first right-angle connector. The other end of the first right-angle connector is attached to the main keel and connected by the sliding of the strip.

[0007] Furthermore, the bottom of the edge keel is formed with a side support plate, the bottom of the main keel is formed with a transverse support plate, and the bottom of the secondary keel is formed with a longitudinal support plate.

[0008] Furthermore, the main keel is formed with symmetrical T-shaped grooves, and the sliding plate is formed with symmetrical T-shaped strips that slide in conjunction with the T-shaped grooves.

[0009] Furthermore, the edge trim keel is formed with a sliding groove that slides into one end of the first right-angle connector, and an opening groove is formed between the two T-shaped grooves to fit into the other end of the first right-angle connector. The opening groove is also located between the sliding piece and the main keel.

[0010] Furthermore, the first right-angle connector has a threaded hole at one end near the edge keel, and the slitting plate has a threaded hole corresponding to the other end of the first right-angle connector.

[0011] Furthermore, a cross-shaped connector is provided at the upper end of the connection between the main keel and the secondary keel.

[0012] Furthermore, two adjacent vertically distributed edge trimming keels are fixed together by bolts and a second right-angle connector, and two adjacent horizontally distributed edge trimming keels are connected together by a horizontal connector.

[0013] Furthermore, mounting holes are provided on the edge trimming keel.

[0014] This utility model has the following beneficial effects: This utility model connects the edge keel and the main keel by means of a slitting plate and a first right-angle connector on the inner side, making the entire structure an integrated connection. Then, the edge keel is fixed to the wall by setting mounting holes on the side, or it is connected by connecting hanging parts and suspension rods on the main keel. The two fixing methods can flexibly adapt to the construction environment. At the same time, the hanging parts and suspension rods are close to the middle and upper part of the ceiling and are not easily seen from the side, which also improves the aesthetics.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Example 1

[0020] Please see Figures 1-2 and Figures 5-6 As shown, this utility model is a prefabricated ceiling component, including an edge keel 1 and a main keel 2. The edge keel 1 and the main keel 2, as well as the adjacent main keels 2, are connected by a secondary keel 3. The main keel 2 is provided with a sliding strip 4, and the edge keel 1 is provided with a sliding first right-angle connector 5. The other end of the first right-angle connector 5 is attached to the main keel 2 and connected by the sliding of the strip 4.

[0021] Furthermore, the bottom of the edge keel 1 is formed with a side support plate 11, the bottom of the main keel 2 is formed with a horizontal support plate 23, and the bottom of the secondary keel 3 is formed with a vertical support plate 31. The ceiling panels overlap on the side support plate 11, the horizontal support plate 23, and the vertical support plate 31.

[0022] Furthermore, the main keel 2 is formed with symmetrical T-shaped grooves 21, and the sliding piece 4 is formed with symmetrical T-shaped strips 41 that slide in conjunction with the T-shaped grooves 21. This sliding fit structure ensures the stable sliding of the sliding piece 4 and the main keel 2, thereby ensuring the limiting effect of the sliding piece 4 on the first right-angle connector 5.

[0023] Furthermore, the edge trim keel 1 is formed with a sliding groove 12 that slides with one end of the first right-angle connector 5. An opening groove 22 is formed between the two T-shaped grooves 21 and is fitted and connected to the other end of the first right-angle connector 5. The opening groove 22 is also located between the sliding piece 4 and the main keel 2. This connection method is more flexible, and the sliding piece 4 can play a role in pre-positioning and connection.

[0024] Furthermore, the first right-angle connector 5 has a threaded hole at one end near the edge keel 1, and the sliding plate 4 has a threaded hole corresponding to the other end of the first right-angle connector 5. Both threaded holes here are used to engage with bolts for clamping and positioning at the connection point.

[0025] Furthermore, a cross connector 7 is provided at the upper end of the connection between the main keel 2 and the secondary keel 3. The cross connector 7 serves to limit the movement and prevent horizontal swaying between the main keel 2 and the secondary keel 3.

[0026] Furthermore, two adjacent vertically distributed edge trimming keels 1 are fixed together by bolts and a second right-angle connector 6, and two adjacent straight edge trimming keels 1 are connected together by a straight connector 8. Both the second right-angle connector 6 and the straight connector 8 slide in the side support plate 11. After connecting two adjacent edge trimming keels 1, they are tightened by bolts to ensure stability.

[0027] Furthermore, the edge trim 1 is provided with mounting holes 13. This embodiment is suitable for prefabricated corridors. The edge trim 1 is directly fixed to the side of the wall through the mounting holes 13 and bolts, without the need for hanging.

[0028] A specific application of this embodiment is as follows: Mounting holes 13 are made on the edge trim 1 to fix it to the wall. When assembling the two vertical edge trim 1s, a 45° angle is first cut at the connection point, and then they are connected using the second right-angle connector 6 and bolts to form the outer frame of the entire ceiling. The slid plate 4 is slidably mounted on the main keel 2 through the cooperation of the T-shaped strip 41 and the T-shaped groove 21. One end of the first right-angle connector 5 slides into the side support plate 11, and the other end of the first right-angle connector 5 is embedded in the opening groove 22. The position of the main keel 2 in the edge keel 1 is determined. After completion, the sliding piece 4 is slid to the side of the first right-angle connector 5 and tightened with bolts. At this time, the edge keel 1 and the main keel 2 are fixed by the cooperation of the sliding piece 4, the first right-angle connector 5 and bolts. The edge keel 1 and the main keel 2, as well as the main keel 2 and the main keel 2 can also overlap with the secondary keel 3. Then, the top of the overlap is positioned by the cross connector 7. The plate is placed on the sliding groove 12, the longitudinal support plate 31 and the transverse support plate 23. Example 2

[0029] like Figure 3-4 As shown, unlike Embodiment 1, the side of the edge keel 1 does not have mounting holes 13. This embodiment is applicable to suspended island ceiling structures.

[0030] Specifically, the top of the main keel 2 and the secondary keel 3 are respectively provided with a first hanging strip 24 and a second hanging strip 32. The upper ends of the first hanging strip 24 and the second hanging strip 32 are provided with sliding hangers 9, and hangers 10 are installed on the hangers 9. Since the hangers 9 and hangers 10 are installed on the main keel 2 or the secondary keel 3, and the main keel 2 and the secondary keel 3 are located in the middle of the edge keel 1, they cannot be seen from the side after installation, which ensures the structural strength while improving the aesthetics.
