Description

Technical Field

[0001] The present invention relates to the field of home improvement technology, and in particular to an assembled ceiling structure, an installation method and an assembled ceiling panel connection device. Background Art

[0002] Driven by market and technical requirements, more and more prefabricated interior decoration technology products are used in building interior decoration. Prefabricated ceiling systems are generally composed of main keels, secondary keels, finishing layers and connecting components. Prefabricated interior ceiling products are required to have the characteristics of dry construction, stable structure and quick installation. Traditional light steel keel ceiling technology generally uses conventional one-way hangers to connect the main keel and the secondary keel, and then bends the short side of the cross-bracing keel and hangs it on the secondary keel. After the gypsum board and the covering keel (secondary keel and cross-bracing keel) are fixed with self-tapping screws, the exposed self-tapping screws are first treated with rust prevention, and then the surface of the gypsum board is smoothed with putty.

[0003] During the installation of traditional light steel keel ceiling technology, after the main keel and the secondary keel are connected with common ceiling hanging plates, the position of the secondary keel can only be adjusted along the installation direction of the secondary keel. If there is an error between the size of the subsequent ceiling board and the installation position of the secondary keel, there is no way to adjust it because the ceiling board is fixed by self-tapping screws, which will affect the quality of the ceiling installation.

[0004] In Chinese invention patent application CN112411859A, a modular ceiling keel structure for interior decoration is disclosed, which includes a longitudinal keel, a transverse keel, a mounting frame and a hanging column. The transverse keel is installed above the longitudinal keel. The left and right side walls inside the longitudinal keel are both provided with lateral slide grooves. The side surfaces of the lateral slide grooves are provided with sliding blocks. The sliding blocks slide in cooperation with the lateral slide grooves. The lower surface of the transverse keel is provided with a plurality of encapsulation side panels. The upper surface of the encapsulation side panels is provided with a first retaining bolt, and the right side surface of the encapsulation side panels is provided with a second retaining bolt. The invention can adjust the distance between the two transverse keels by setting the sliding block to slide with the lateral slide groove, but still cannot adjust the installed ceiling panels.

[0005] In Chinese invention patent application CN115110688A, a fine ceiling assembly device is disclosed, including a main keel, a plurality of first openings are arranged on the surface of the main keel, threaded rods are connected to the threads inside some of the openings, expansion screws are connected to the top of the threaded rods, and the threaded rods are installed on the indoor top wall through the expansion screws, a plurality of connectors are slidably arranged on the surface of the main keel, second openings are arranged on both sides of the connectors, and fixing screws are arranged inside the second openings, and the connectors are fixedly connected to the main keel through the fixing screws, and the bottom of the connector is connected to a secondary keel, and extension plates are connected to both sides of the bottom of the secondary keel, and a ceiling is arranged at the bottom of the extension plate, and a plurality of screw holes are arranged on the surface of the extension plate, and the extension plate is fixedly connected to the ceiling through screws arranged inside the screw holes. This solution can adjust the ceiling plate in two directions, but it is still impossible to adjust the ceiling plate in four directions after installation. Summary of the invention

[0054] In order to better understand the technical solution of the embodiment of the present invention, the embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0055] It should be clear that the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present invention.

[0056] Example 1

[0057] See also Figures 1 to 12 The embodiment of the present invention discloses an assembled ceiling structure, including a main keel 50, two mutually parallel auxiliary keels 40, a ceiling board 10, a connecting profile 20, a horizontal bracing keel 30 and a four-way sliding mechanism 60.

[0058] See also Figure 1In an embodiment of the present invention, the main keel 50, the secondary keel 40 and the cross-bracing keel 30 are all light steel keels. Both ends of the main keel 50 are fixedly connected to the roof through the hanger 70. The main keel 50 can also be directly fixed to the roof using rivets and other connecting parts. The structures of the main keel 50, the secondary keel 40 and the cross-bracing keel 30 are all U-shaped structures commonly seen in light steel keels. A number of grooves are processed on the main keel 50, and the secondary keel 40 is connected to the grooves of the main keel 50. The two secondary keels 40 are parallel to each other and perpendicular to the main keel 50.

[0059] See also Figures 2 to 5 Two straight grooves 11 are arranged in parallel on the back of the ceiling plate 10, and a connecting structure 12 is arranged on the side walls of each straight groove 11. The back of the ceiling plate 10 is the upper surface of the ceiling plate, that is, the surface that is not observed after installation.

[0060] The connecting profile 20 is cut from a whole section of profile. After the straight groove 11 is opened on the back of the ceiling panel 10 and the connecting structure 12 is set, the connecting profile 20 can be inserted into the straight groove 11 and the connecting profile 20 is combined with the connecting structure 12. In this way, the connecting profile 20 can be connected to the ceiling panel 10. A proper amount of glue can be applied between the connecting profile 20 and the connecting structure 12 to increase the connection strength. Since the straight groove 11 runs through the ceiling panel 10, that is, it completely passes through the solid part of the ceiling panel 10 in the length direction of the straight groove 11, the connecting profile 20 can be inserted at any end of the straight groove 11.

[0061] After the connecting profile 20 is connected to the ceiling panel 10, the cross-bracing keel 30 can be connected to the connecting profile 20 through the fastener 13, and the fastener 13 does not contact the front of the ceiling panel 10. The fastener 13 can be a self-tapping screw, or a stud, etc. In this embodiment, the fastener 13 is passed through the cross-bracing keel 30 and the connecting profile 20 to achieve the fixation of the two. A certain space can be set between the connecting profile 20 and the straight-through groove 11 to accommodate the fastener 13, so that the fastener 13 does not contact the ceiling panel 10. If the fastener 13 contacts the ceiling panel 10, it is also set so that the fastener 13 does not contact the front of the ceiling panel 10.

[0062] The four-way sliding mechanism 60 is disposed between the secondary keel 40 and the cross-bracing keel 30 in the height direction. The four-way sliding mechanism 60 includes an X-direction connecting portion 61 and a Y-direction connecting portion 62 which are connected as one body.

[0063] The X-connecting portion 61 is slidably connected to the secondary keel 40 , and the Y-connecting portion is slidably connected to the transverse keel 30 , so that the transverse keel 30 and the secondary keel 40 are perpendicular to each other.

[0064] The assembled ceiling structure of the present invention can avoid exposing self-tapping screws on the ceiling board by setting straight-through grooves on the ceiling board and connecting the connecting profiles with the cross-bracing keels, and the self-tapping screws are rust-proofed. The cross-bracing keels and the auxiliary keels are connected by a four-way sliding mechanism, so that the position of the ceiling board can be adjusted, thereby improving the installation efficiency of the ceiling board and the installation error tolerance of the ceiling board.

[0065] See also Figure 5 In this embodiment, the connection structure 12 includes a horizontal groove formed on the side wall of the straight groove 11, and the connection profile 20 has an insertion portion 23 that can be inserted into the horizontal groove. The horizontal groove can be processed synchronously with the straight groove 11 by a tool. The cross section of the straight groove is rectangular, and the horizontal groove is arranged at the bottom of the straight groove 11.

[0066] See also Figure 4 The connecting profile 20 is a "J"-shaped structure, including a flat plate portion 21 whose upper surface protrudes from the upper surface of the ceiling panel 10, and extension portions 22 extending into the straight groove 11 are arranged on both sides of the flat plate portion 21, and the extension portions 22 are connected to the insertion portions 23. The structure of the connecting profile 20 is simple and can be formed by directly bending a plate. The length of the connecting profile 20 is the same as the length of the straight groove 11, so that the connecting profile 20 has the maximum length and has the best load-bearing effect. The straight groove 11 can be arranged to be arranged along the length direction of the ceiling panel 10 and close to the edge of the ceiling panel 10.

[0067] See also Figures 6 to 12 , the specific structure of the four-way sliding mechanism 60 is introduced below. In this embodiment, the X-direction connecting portion 61 of the four-way sliding mechanism 60 includes a thin sheet-shaped first connecting plate 610. The first connecting plate 610 is stamped from a metal plate with a thickness not exceeding 2 mm. The main body of the first connecting plate 610 is a rectangular flat plate. A first bending edge 612 that can be bent upward and hooked and hung on the secondary keel 40 is provided at two opposite first side edges of the first connecting plate 610. The number of the first bending edges 612 can be set to 2 to 4. A second bending edge 614 that can be bent downward is provided at two opposite second side edges 613 of the first connecting plate 610. The bending position of the first bending edge 612 can be determined according to the actual width of the secondary keel 40, so that the adaptability of the first connecting plate 610 can be improved. After the X-direction connecting portion 61 is hung on the secondary keel 40, the X-direction connecting portion 61 can slide relative to the secondary keel 40.

[0068] The Y-axis connecting portion 62 includes a thin sheet-shaped second connecting plate 620, which is stamped from a metal plate with a thickness not exceeding 2 mm. The second connecting plate 620 is disposed below the first connecting plate 610, and a downwardly bent clamping piece 621 is disposed on the second connecting plate 620, and clamping portions 622 are disposed at both ends of the clamping piece 621. Fig.13 As shown, Fig.13 The cross-sectional view of the cross-bracing keel 30 is shown. The cross-bracing keel 30 is provided with a guide groove 31 which is slidably connected to the clamping portion 622 .

[0069] The Y-connecting portion 62 is attached to the lower surface of the X-connecting portion 61, and then the second bending edge 614 of the X-connecting portion 61 is bent toward the lower surface of the first connecting plate 610 to hold the second connecting plate 620, thereby fixing the second connecting plate 620 on the first connecting plate 610. The ceiling panel 10 is lifted upward, and the guide groove 31 of the horizontal bracing keel 30 is combined with the clamping portion 622, that is, the horizontal bracing keel 30 is hung on the clamping portion 622, so that the horizontal bracing keel 30 slides relative to the four-way sliding mechanism 60. In addition, the sliding direction of the horizontal bracing keel 30 is perpendicular to the auxiliary keel 40.

[0070] The four-way sliding mechanism 60 of the embodiment of the present invention is composed of two thin plate structures, which takes up little space when stored and can be easily assembled at the installation site. It can reliably connect the cross-bracing keel 30 and the auxiliary keel 40 to achieve the four-way sliding function. In addition, since a thin plate structure is adopted, its structure is compact and low in cost, and the vertical space occupied between the cross-bracing keel 30 and the auxiliary keel 40 is small.

[0071] The assembled ceiling structure of the embodiment of the present invention can move the ceiling panel 10 in the front, back, left, and right directions after the ceiling panel 10 is installed on the secondary keel 40, so that the ceiling panel 10 can be easily adjusted.

[0072] Example 2

[0073] The embodiment of the present invention discloses an assembled ceiling panel connection device, which is used to fix the ceiling panel on the secondary keel. The assembled ceiling panel connection device includes a ceiling panel, a connection profile and a cross-bracing keel. Two straight through grooves that penetrate the ceiling panel are arranged in parallel on the back of the ceiling panel, and a connection structure is arranged on the side walls of each of the straight through grooves. The connection profile is inserted into the straight through groove and combined with the connection structure. The cross-bracing keel is fixedly connected to the connection profile by a fastener, and the fastener does not contact the ceiling panel.

[0074] The ceiling board, connecting profile and cross-bracing keel structure are the same as those in Example 1. The ceiling board connecting device does not need to fix the ceiling board with self-tapping screws on the lower surface of the ceiling board, does not need to perform rust prevention treatment on the self-tapping screws, and then use putty to smooth the surface of the ceiling board, which simplifies the process and keeps the lower surface of the ceiling board beautiful.
