Description

Technical Field

[0001] The utility model relates to the technical field of ceilings, in particular to a ceiling corner anti-cracking structure. Background Art

[0002] Home decoration ceiling is a common part of home decoration. The classification of ceiling varies according to the material of the decorative panels. The ceiling decoration materials are the main basis for distinguishing the names of the ceiling. There are mainly: light steel keel gypsum board ceiling, gypsum board ceiling, mineral wool board ceiling, plywood ceiling, special-shaped long aluminum gusset ceiling, square painted aluminum gusset ceiling, stained glass ceiling, aluminum honeycomb perforated sound-absorbing panel ceiling, whole room duplex ceiling, etc.

[0003] In order to improve the quality of the finished ceiling, the prior art has made many improvements to the ceiling structure, such as the patent with the publication number CN215716467U, which discloses a ceiling corner anti-cracking structure, which includes a wooden keel installed on the ceiling and a connecting plate obliquely across the corner of the wooden keel and installed on the upper surface of the wooden keel, and the lower surface of the corner of the wooden keel is fixedly installed with a first L-shaped clamp. Compared with the prior art, the utility model ceiling corner anti-cracking structure is provided with a connecting plate obliquely across the corner of the wooden keel and installed on the upper surface of the wooden keel, so as to avoid the concentration of force at the corner of the wooden keel, so that the force is uniform, and the keel displacement at the weak corner of the wooden keel caused by the concentrated stress can be prevented, thereby preventing the occurrence of cracks at the corner of the ceiling, and the first L-shaped clamp is provided on the lower surface of the wooden keel corner, and there is no splicing gap at the corner of the ceiling board, which can further effectively avoid the cracking of the ceiling corner.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] The above-mentioned comparative documents can prevent cracks at the joints between the ceiling panel and the side walls. However, in reality, many home decorations will use gypsum boards to hang out a rectangular raised ceiling at the ceiling position. Since the ceiling is not a full ceiling, the keel cannot be made into an integral shape. Since the wall and the keel will deform to different sizes in the later stage, it will cause cracks at the right-angle corners of the ceiling panel, affecting the aesthetics of the ceiling in the later stage. Therefore, this field urgently needs to improve the anti-cracking structure at the ceiling corners, so as to solve the defects of the existing technology. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] As a technical optimization scheme of the utility model, the adjustment unit includes an extrusion strip 9 arranged in the clamping frame 6 and adapted to the connecting plate 4. One side of the connecting plate 4 and one side of the extrusion strip 9 are provided with adapted extrusion bevels 10. A plurality of adjustment bolts 11 are passed through and threadedly connected to one side of the clamping frame 6. A limiting nut 12 is threadedly connected to the side of the adjustment bolt 11, and one end of the adjustment bolt 11 is against the side of the extrusion strip 9.

[0032] Specific implementation method in this embodiment: When installing the ceiling, first determine the four corner positions of the ceiling, and use expansion bolts to install the installation plate 7. After the four connecting plates 5 are installed, the horizontal keel frame 1 and the longitudinal keel frame 2 are plugged into the corresponding clamping frame 6 through the connecting plate 4 to achieve a pre-fixing effect. The installer plugs the extrusion strip 9 into the clamping frame 6 and rotates the adjusting bolt 11. The adjusting bolt 11 pushes the extrusion strip 9 to move, and squeezes the connecting plate 4 by squeezing the bevel 10, so that the adjacent horizontal keel frame 1 and the longitudinal keel frame 2 The corners are in a plane, and the limit nuts 12 are tightened to fix the position of the adjusting bolts 11. The horizontal keel frame 1 and the longitudinal keel frame 2 are fixed to the indoor ceiling again through mounting parts such as screw rods, and the ceiling panel 8 is fixed to the lower surfaces of the horizontal keel frame 1 and the longitudinal keel frame 2 through mounting parts such as self-tapping screws. Due to the connection of the connecting plate 5 and the clamping frame 6, the horizontal keel frame 1 and the longitudinal keel frame 2 are connected as a whole at the intersection corner, and have high strength, which prevents the deformation of the corner connection in the later stage from causing the ceiling panel 8 to crack.

[0033] It is worth noting that the number of the above-mentioned connecting plates 5 is determined according to the on-site ceiling conditions, and the above-mentioned embodiment is only taken as an example of a rectangular ceiling that needs to be suspended from the top of the room.

[0036] Specific implementation method in this embodiment: during installation, first fix the longitudinal keel frame 2 to the indoor ceiling, and when installing the transverse keel frame 1, plug the plug strip 13 into the plug groove 14. The cross-section of the plug strip 13 and the plug groove 14 are an adaptive right-angle trapezoidal shape. When the adjustment unit is used to adjust the transverse keel frame 1 and the longitudinal keel frame 2, the plug strip 13 is tightly plugged into the plug groove 14, thereby improving the connection strength at the corner between the transverse keel frame 1 and the longitudinal keel frame 2, and reducing the probability of deformation of the main keel 3 at the corner in the later stage. The corner reinforcement plate 16 improves the strength between the main keel 3 and the secondary keel 15, and reduces the probability of deformation of the transverse keel frame 1 and the longitudinal keel frame 2 in the later stage.

[0038] See also Figure 1-Figure 6This embodiment includes all the above embodiments, and also includes: a through stepped hole 17 is opened on the upper side of the connecting plate 4, a fixing bolt 18 with one end threadedly connected to the side of the main keel 3 is passed through the stepped hole 17, a limiting ring 19 adapted to one end of the adjusting bolt 11 is fixedly connected to the side of the extrusion strip 9, and the ceiling panel 8 located at the corner position of the horizontal keel frame 1 and the longitudinal keel frame 2 is L-shaped.

[0039] Specific implementation methods in this embodiment: the connecting plate 4 is installed by means of fixing bolts 18. At the position where the connecting plate 4 needs to be installed, it is fixed and installed by means of fixing bolts 18, thereby improving the ease of use of the overall device and reducing the production cost of the main keel 3. The limiting ring 19 is used to limit one end of the adjusting bolt 11. At the same time, one end of the adjusting bolt 11 rotates in the limiting ring 19, and the extrusion strip 9 will not be displaced. When installing the ceiling panel 8 located at the corner position of the horizontal keel frame 1 and the longitudinal keel frame 2, the ceiling panel 8 is cut into an L shape, so that the ceiling panel 8 at the corner is a whole. It is fixed with self-tapping screws to improve the integrity of the corner and further reduce the cracking of the ceiling panel 8.
