Description

Technical Field

[0001] This utility model relates to the field of ceiling keel technology, specifically a gypsum ceiling keel. Background Technology

[0002] In the field of building decoration, gypsum board ceilings are widely used due to their flatness and aesthetics. As the skeleton of the ceiling, the stability of the structure and the ease of installation of the keel system are directly related to the quality and efficiency of the entire ceiling project.

[0003] Traditional ceiling keel systems typically consist of a main keel and secondary keels. The main keel is connected to the building ceiling via hangers, while the secondary keels are vertically and crosswise connected below the main keel to fix the gypsum board. However, existing keel structures often use simple hooks or clips for connection, resulting in limited connection strength between the main and secondary keels. Under external forces or long-term loads, these connections are prone to loosening and deformation, affecting the flatness and safety of the ceiling. Furthermore, traditional hangers have a simple structure and concentrated stress points, which may lead to excessive local stress on the main keel. In addition, the fixing methods between the secondary keels and the connectors are not secure enough, and the rigidity and stability of the overall structure need to be improved. Therefore, there is an urgent need in this field for a gypsum board ceiling keel structure that offers a more secure connection, a more stable structure, and easier installation. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gypsum ceiling keel, comprising a main keel, three secondary keels connected below the main keel, connectors installed at the connection points between the three secondary keels and the main keel, each connector comprising a connecting plate located between the main keel and the secondary keels, two side plates installed at the front and rear ends of the connecting plate, the two side plates located on the outer walls of both sides of the main keel, a hanger connected to the top of the two side plates, two wrapping plates installed on the left and right sides of the lower end of the connecting plate, the two wrapping plates located on both sides of the secondary keels, and two wrapping strips connected to the lower ends of the two wrapping plates.

[0005] Preferably, the hoisting device includes two bent plates, one end of each bent plate is connected to the top of the two side plates, the two bent plates are located on both sides of the upper end of the main keel, a hoisting frame is connected above the two bent plates, the lower sides of the hoisting frame are connected to the center of the two bent plates, and a hoisting groove is provided at the center of the upper end of the hoisting frame.

[0006] Preferably, the hoisting frame is a U-shaped hoisting frame, and the lower two sides of the hoisting frame are respectively connected to two bent plates by screws.

[0007] Preferably, the two side plates are connected to the main keel by screws.

[0008] Preferably, the wrapping plate is connected to the secondary keel by screws.

[0009] Preferably, the wrapping strip is connected to the secondary keel by screws.

[0010] Beneficial effects

[0011] This utility model provides a gypsum board ceiling keel with the following beneficial effects: Through the connector, the two upper side plates clamp the main keel from both sides, while the two lower wrapping plates and wrapping strips cover and fix the secondary keel from both sides and bottom, forming an all-round wrapping connection. This tightly combines the main and secondary keels into a high-rigidity whole, greatly enhancing the structural stability and anti-shaking ability of the keel system. Furthermore, the hanger is connected to the top of the side plate of the connector through two bending plates, and the force is transferred to the U-shaped hanger frame, distributing the single hanger force to both sides of the upper end of the main keel, avoiding stress concentration, making the hanger more stable and reliable, and further ensuring the flatness of the main keel.

[0012] Using screws for connection not only ensures a secure connection but also simplifies the construction process, ensures consistency in the connection of each component, reduces human error, and improves the reliability and efficiency of installation. Attached Figure Description

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example: Please refer to Figure 1-4A type of gypsum ceiling keel includes a main keel 1, three secondary keels 2 connected below the main keel 1, connectors installed at the connection points between the three secondary keels 2 and the main keel 1, each connector including a connecting plate 3 located between the main keel 1 and the secondary keels 2, two side plates 4 installed at the front and rear ends of the connecting plate 3, the two side plates 4 located on the outer walls of the two sides of the main keel 1 respectively, and a hanger connected to the top of the two side plates 4, two wrapping plates 5 installed on the left and right sides of the lower end of the connecting plate 3, the two wrapping plates 5 located on the sides of the secondary keels 2 respectively, and two wrapping strips 6 connected to the lower end of the two wrapping plates 5.

[0020] During the construction of the plaster ceiling, first, mark a 10-15mm horizontal line on the interior wall based on the bedroom floor. Measure this line to the ceiling design elevation and draw a height line at that point. Use a level to determine the horizontal height line of the entire room. Use the same method to create horizontal height lines on other walls. All interior finishing trades use this 10-15mm line. Generally, the ceiling elevation line is marked 10mm upwards to form the edge joist line, allowing for the thickness of the plasterboard. The deviation should not exceed 3mm. Use 25mm gas nails and 18mm steel nails, with a nail spacing between 400mm and 500mm, to fix the edge joists to the ceiling. Then, mark the accurate position on the top surface of the floor slab. Generally, use Φ6 threaded rods to fix them to the bottom surface of the cast-in-place floor slab. For Φ6 threaded rods, the drilling depth should be ≥50mm, and the drilling diameter should be the outer diameter of the threaded rod plus 4mm. The drilling depth should completely cover the expansion joint. The cap is covered, the suspension wire is perpendicular to the floor slab, and the spacing between the screws is no more than 1200mm. After installation, the workers will put the processed connector on top of the main keel 1, and then connect it to the screws through the hoist to suspend the main keel 1. The screws will be adjusted to keep the main keel 1 at the specified height. The main keel 1 will be wrapped and initially fixed by the cooperation of the connecting plate 3 and the two side plates 4. Then, the two side plates 4 will be fixed to both sides of the main keel 1 with screws to stabilize the main keel 1. After the main keel 1 is fixed, the workers will insert the designated secondary keel 2 between the two wrapping plates 5, and then use a hammering method to bend the two wrapping strips 6 to the bottom of the secondary keel 2. Finally, the wrapping plates 5 and wrapping strips 6 will be connected to the secondary keel 2 with screws to complete the installation of the main keel 1 and the secondary keel 2. Then, the plasterboard will be installed.

[0021] In the specific implementation process, the hoisting device includes two bent plates 7. One end of the two bent plates 7 is connected to the top of the two side plates 4 respectively. The two bent plates 7 are located on both sides of the upper end of the main keel 1. A hoisting frame 8 is connected above the two bent plates 7. The lower sides of the hoisting frame 8 are connected to the center of the two bent plates 7 respectively. A hoisting groove 9 is opened at the center of the upper end of the hoisting frame 8.

[0022] When hoisting the main keel 1, the hoisting frame 8 is connected to the two bending plates 7 by screws. Then, the bottom end of the screw is embedded into the hoisting groove 9. The hoisting groove 9 is used to lock and limit one end of the screw, thus realizing the hoisting operation of the main keel 1.

[0023] In the specific implementation process, the hoisting frame 8 is a portal-shaped hoisting frame 8, and the lower two sides of the hoisting frame 8 are connected to two bent plates 7 by screws.

[0024] The portal-shaped hoisting frame 8, in conjunction with two bending plates 7, can distribute the single hoisting force to both sides of the upper end of the main keel 1, thus avoiding stress concentration.

[0025] In the specific implementation process, the two side plates 4 are connected to the main keel 1 by screws, the wrapping plate 5 is connected to the secondary keel 2 by screws, and the wrapping strip 6 is connected to the secondary keel 2 by screws.

[0026] The use of screws for installation simplifies the construction process, ensures consistency in the connection of various components, reduces human error, and improves the reliability and efficiency of installation.

[0027] The connector can be sourced and processed on-site. It uses a hollow square tube with a specification larger than the main keel 1, cuts it open at the top center, and uses a hammering method to obtain a bending plate 7 and two side plates 4. Then, it cuts grooves at both ends of the bottom and bends them to obtain two wrapping plates 5 and two wrapping strips 6.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
