[0030] An embodiment of this application provides a prefabricated ceiling system. Figure 1 A schematic diagram illustrating the overall structure of a prefabricated ceiling system according to an embodiment of this application is shown. Figure 1 As shown, the prefabricated ceiling system includes prefabricated ceiling panels 7, hanging clips 4, and side connectors 5.

[0031] Figure 2 This schematically illustrates the structure of the prefabricated ceiling panel in the groove of a prefabricated ceiling system according to an embodiment of this application. Figure 2 As shown, the prefabricated ceiling panel 7 has a groove 701 on its side end for fixing the prefabricated ceiling panel.

[0032] Figure 3 The diagram schematically illustrates the front structural view of the hanging bracket of a prefabricated ceiling system according to an embodiment of this application. Figure 3 As shown. The hanging clip 4 includes a hanging clip body 401, a first fixing part 402, and a second fixing part 403. The first fixing part 402 is disposed on a first side of the hanging clip body 401 for connecting to the ceiling 1; the second fixing part 403 is disposed on a side of the hanging clip body 402 other than the first side where the first fixing part 402 is disposed, for connecting to the side connector 5.

[0033] Figure 5 A schematic diagram illustrating the structure of a side connector of a prefabricated ceiling system according to an embodiment of this application is shown. Figure 5 As shown, the side connector 5 includes a main body 501, a first connecting part 502, and a second connecting part 503. The first connecting part 502 is fixedly connected to the first end of the main body 501, and its end is bent and inserted into the groove 701 of the prefabricated ceiling panel 7 to connect with it. The second connecting part 503 is fixedly connected to the side of the main body 501 away from the prefabricated ceiling panel 7 and is detachably connected to the second fixing part 403 of the hanging clip 4. The second end of the main body 501 is fixedly connected to the prefabricated ceiling panel 7 to ensure secure fixation and even stress distribution.

[0034] Both ends of the prefabricated ceiling panel 7 are connected to the hanging clips 4 via side connectors 5. In the embodiments of this application, each side connector 5 can fix one end of the prefabricated ceiling panel 7. In actual construction, both ends of the prefabricated ceiling panel need to be fixed, that is, the ends of the two opposite sides of the prefabricated ceiling panel 7 with grooves can be fixed to the hanging clips 4 via a side connector 5. Alternatively, multiple side connectors arranged at intervals can be used to achieve fixation to further ensure the installation is firm.

[0035] In the embodiments of this application, for ease of description, the relative positions and cooperation relationships of each component in the prefabricated ceiling system are described in the installed state, and the relative positions of each component or structure are described in the directions shown in the accompanying drawings, which does not imply any limitation on this application.

[0036] In the embodiments of this application, a mutually cooperating hanging bracket and side connector structure is designed. The side connector is fixedly connected to the prefabricated ceiling panel and detachably connected to the hanging bracket. During installation, the prefabricated ceiling panel can be installed simply by connecting the side connector to the detachable connection position of the hanging bracket, eliminating the need for complex operations and greatly improving installation efficiency. The side connector can be pre-connected to the prefabricated ceiling panel before being installed with the hanging bracket. The side connector is connected to the prefabricated ceiling panel through an insertion fit with the end groove of the prefabricated ceiling panel, thereby ensuring the relative positional accuracy between the various structures during installation and ensuring the flatness of the prefabricated ceiling panel after installation. Both ends of the prefabricated ceiling panel use side connectors of the same structure to connect to the hanging bracket. This improves versatility and enhances structural symmetry, ensuring installation accuracy and flatness. It also avoids installation errors caused by structural errors that may occur when using multiple connection structures, further improving the flatness after installation.

[0037] The prefabricated ceiling panel 7 has a groove 701 at its end for easy installation and fixing. In the embodiments of this application, the end structures of the prefabricated ceiling panel 7 on both sides of the groove 701 are different. See also Figure 2 The upper part of the groove 7 (i.e., the side of the prefabricated ceiling panel 7 located at the top after installation) has a staggered layer 702 at the end of the panel, making the panel structure in this part shorter than the panel structure below. Specifically, the length of the end of the prefabricated ceiling panel 7 at the staggered layer 702 is shorter than the length of the end of the prefabricated ceiling panel 7 located elsewhere. The staggered layer 702 can be obtained by cutting the panel so that after the side connector 5 is installed, the side of the side connector 5 does not protrude from the end of the prefabricated ceiling panel 7, enabling a tight fit between adjacent prefabricated ceiling panels after installation and improving aesthetics.

[0038] In the embodiments of this application, the designed structure of the hanging bracket 4 and the side connector 5 allows for the splicing of multiple prefabricated ceiling panels 7, and is universal between prefabricated ceiling panels and walls, as well as between adjacent prefabricated ceiling panels, without the need for separately designed installation structures applicable to adjacent prefabricated ceiling panels and between prefabricated ceiling panels and walls. When there are multiple prefabricated ceiling panels, the side surfaces of the first connecting portions 502 of the side connectors 5 between adjacent prefabricated ceiling panels 7 fit together, enabling mutual support.

[0039] In an embodiment of this application, the first connecting portion 502 of the side connector 5 includes a third bent portion 5021 and a fourth bent portion 5022 connected to each other. The first end of the third bent portion 5021 is fixedly connected to the main body portion 501, and the second end is connected to the first end of the fourth bent portion 5022. The second end of the fourth bent portion 5022 is suspended to be inserted into the groove 701. The third bent portion 5021 is perpendicular to the main body portion 501, and the fourth bent portion 5022 is perpendicular to the third bent portion 5021 and extends towards the main body portion 501 to form a slot covering the plate structure at the staggered layer 702. It should be noted that in this embodiment, "perpendicular" refers to an angle between the two portions. , The angle is the error angle, and its specific value can be set according to the actual situation. In addition, in order to achieve a close fit and improve the aesthetics of the prefabricated ceiling panel after installation, the third bend 5021 of the side connector is also configured such that when it is inserted with the prefabricated ceiling panel, the side of the third bend 5021 is flush with the side of the prefabricated ceiling panel 7 on the side without the staggered layer 702.

[0040] In the embodiments of this application, to further improve the stability after installation, the provided prefabricated ceiling panel system also includes a fastener 6. For installing the fastener 6, the side connector 5 is further provided with a third connecting portion 504. The third connecting portion 504 is located on the side of the side connector 5 away from the mating prefabricated ceiling panel 7. An installation area for installing the fastener 6 is formed between the third connecting portion 504 and the main body portion 501 of adjacent side connectors, thereby allowing the fastener 6 to be inserted between the third connecting portion 502 and the main body portion 501 of adjacent side connectors. The fastener 6 improves the stability after installation and also ensures that adjacent side connectors are at the same horizontal level, reducing the risk of adjacent prefabricated ceiling panels not being at the same height due to installation errors or structural errors of the hanging clip 4, thus improving the flatness of the prefabricated ceiling panel after installation.

[0041] The third connecting part 504 can be disposed on the main body 501 or on the second connecting part 503. For ease of processing, in the embodiments of this application, the third connecting part 504 is a plate structure parallel to the main body 501, with its first end connected to the second connecting part 503 and its second end suspended, thereby forming an area for mounting the fastener 6 between the main body 501, the second connecting part 503, and the third connecting part 504. The projection of the third connecting part 504 along the length of the main body 501 is within the range of the main body 501, that is, the third connecting part 504 is not longer than the end of the fastener 501, to avoid interference between the third connecting parts 504 of adjacent side connecting parts 5. Simultaneously, it also ensures that when the side connecting part is disposed between the prefabricated ceiling panel and the wall, that is, corresponding to… Figure 1The leftmost side connector is positioned so that the third connector 504 does not interfere with the wall surface, ensuring the versatility of the side connector.

[0042] In some other embodiments, the third connecting part 504 can also be provided on the main body part 501. For example, the third connecting part can be designed as an "L"-shaped bent structure to form a space between it and the main body part to accommodate the fastener 6, achieving the same effect as the above embodiment.

[0043] Figure 6 This illustration schematically shows a structural diagram of a fastener in a prefabricated ceiling system according to an embodiment of this application. In this embodiment, the third connecting portion 504 includes a fixing groove 5042, and the surface of the fastener 6 is provided with a fixing protrusion 601 that mates with the fixing groove 5042. The structure of the fixing groove and the fixing protrusion mates together ensures the tightness of the fastener 6 and the adjacent side connecting member 5. In some embodiments, the fixing groove 5042 can be arc-shaped, and the third connecting portion 504 can include a recess 5041, forming the fixing groove 5042 through the arc-shaped recess 5041. Correspondingly, the fixing protrusion 601 is also arc-shaped. In other embodiments, the cross-sectional shape of the fixing groove 5042 can also be rectangular or other shapes, as long as it allows the fastener 6 to be inserted from the side to connect to the adjacent side connecting member 5.

[0044] In the embodiments of this application, the number of second fixing parts 403 of the hanger 4 is multiple, and the multiple second fixing parts 403 are spaced apart on the second side of the hanger body 401 to realize the installation of the side connector 5.

[0045] Each hanger 4 can be provided with two or more second fixing parts 403, the number of which can be flexibly set according to actual needs. In the embodiment of this application, each hanger 4 is provided with two second fixing parts 403. The second fixing parts 403 can be provided on the side or bottom surface of the hanger body, that is, on the side other than where the first fixing part 402 is provided. When the second fixing part 403 is provided on the side of the hanger body, it can extend along the direction of the side and bend downward to ensure that the end faces downward, so as to facilitate the connection with the side connector.

[0046] In the embodiments of this application, a first fixing part 402 is disposed on a first side of the hanging bracket body 401, which is the upper side of the hanging bracket body 401 during installation. A second fixing part 403 is disposed on a second side of the hanging bracket body 401, which is the side opposite to the first side, i.e., the lower side of the hanging bracket body 401 during installation. There are two second fixing parts 403, located at the two ends of the second side respectively, and each can be connected to a side connector, thereby enabling them to be disposed at the junction of adjacent prefabricated ceiling panels to install and fix the two side connectors at the junction of the two prefabricated ceiling panels.

[0047] In the embodiments of this application, for ease of installation, the hanger and the side connector are connected by hooks. In other embodiments, snap-fit ​​or other detachable connection methods may also be used. When a hook connection is used, the second fixing part 403 includes a first hook part 4031, and the second connecting part 503 includes a second hook part 5031 that engages with the first hook part 4031. During installation, the second hook part 5031 is engaged with the first hook part 4031, so that the end of the second hook part 5031 is embedded in the hook groove 4032 of the first hook part 4031 to achieve a fixed connection.

[0048] In the embodiments of this application, a first hook portion 4031 is provided on both sides of the second fixing portion 403, and the second connecting portion 503 includes a number of second hook portions 5031 equal to the number of first hook portions 4031. Connecting via multiple hooks ensures connection reliability, prevents misalignment after connection, and guarantees installation accuracy.

[0049] In the embodiments of this application, the first end of the main body 501 of the side connector 5 is fixed to the side end of the prefabricated ceiling panel by an insertion method, and the second end of the main body 501 has a through hole for fixing the main body 501 to the prefabricated ceiling panel 7 with screws. In some other embodiments, the fixing connection can also be achieved by means of adhesive bonding, thereby achieving a firm fixation between the side connector 5 and the prefabricated ceiling panel 7 by fixing from both sides. Compared with adhesive bonding, screw connection has higher installation accuracy and is more suitable for the installation of prefabricated ceiling panels with higher precision requirements.

[0050] The hanging bracket 4 is indirectly connected to the ceiling, which can be achieved through a hanger rod or ceiling joists. In the embodiments of this application, the hanging bracket 4 is connected to the ceiling via ceiling joists 3. In this case, the prefabricated ceiling system also includes ceiling joists 3, which are fixedly connected to the ceiling. The hanging bracket 4 and ceiling joists 3 are connected via a first fixing part 402. Figure 4 This schematically illustrates a side view of the hanging bracket of a prefabricated ceiling system according to an embodiment of this application, as shown below. Figure 4As shown, the first fixing part 402 includes a first bending part 4021 and a second bending part 4022. The first end of the first bending part 4021 is fixedly connected to the first side of the hanging bracket body 401, and the second end is fixedly connected to the first end of the second bending part 4022. The second end of the second bending part 4022 is suspended. A connecting groove that cooperates with the ceiling keel 3 is formed between the first bending part 4021, the second bending part 4022 and the hanging bracket body 401.

[0051] During installation, hang the clips on the ceiling joists 3 so that the ceiling joists are embedded in the connecting grooves, and then fix the clips to the ceiling joists with screws.

[0052] In the embodiments of this application, the ceiling joist 3 is fixedly connected to the ceiling via hangers 2, and also fixedly connected to the wall to ensure stability. Using hangers to fix the ceiling joist is existing technology and will not be described further here.

[0053] The prefabricated ceiling system provided by this utility model is installed as follows: According to the dimensions of the prefabricated ceiling panel 7, hangers 4 are attached and fixed at designated positions on the ceiling joists 3, while simultaneously connecting the side connectors 5 to the prefabricated ceiling panel 7. The prefabricated ceiling panel 7 is then raised to a height close to the ceiling joists 3, aligning the first connecting portion 502 of each side connector 5 with the second fixing portion 403 of the hanger 4. Subsequently, the prefabricated ceiling panel 7 is further pushed upwards, causing the first connecting portion 502 to engage with the second fixing portion 403, thus completing the installation.
