[0002] In the practice of building decoration, it is found that the "L"-shaped lower surface of the peripheral box ceiling, reflective ceiling, step-down ceiling and other ceilings often cracks. In order to solve this problem, some people in the industry add corner guards, some add diagonal braces, and some strengthen the base plate, but the effect is not good, and cracks still occur. The original problems are the following: 1. The arrangement direction of the main keel and the secondary keel is different, and the base at the corner of the plane is divided into two parts, and the stress is concentrated at the joint of the two parts; 2. Some structures of the ceiling base are loose, and the structure of the ceiling base changes; 3. The distance between the hanger, main keel, and secondary keel is too large, and the local drooping deformation and the surface flatness deviation of the ceiling base are large, and the stress is concentrated. Utility Model Content

[0003] In view of the above-mentioned shortcomings or deficiencies of the prior art, the technical problem to be solved by the present application is to provide an anti-cracking ceiling structure.

[0004] To solve the above technical problems, this application is implemented through the following technical solutions:

[0005] A crack-proof ceiling structure comprises: a wall, a roof surface, a ceiling base layer, and a ceiling surface layer. The ceiling base layer is fixed to a corner of the top surface of a room enclosed by the wall and the roof surface, and the ceiling surface layer is fixed to the lower surface of the ceiling structure by self-tapping screws. The base layer connection at the plane corner of the ceiling structure is arranged to form an integrated structure.

[0006] Furthermore, the ceiling base layer includes a hanging piece, a main keel, a secondary keel, a side keel, and a positive corner keel. The main keel is hung below the roof surface by the hanging piece, the secondary keel is vertically fixed to the lower end of the main keel, one end of the secondary keel is inserted into the opening of the side keel, and the other end of the secondary keel is inserted into the opening of the positive corner keel. The side keel is fixed to the wall or the roof surface by a nail.

[0007] Furthermore, the hanging member is composed of an expansion head, a hanging rod, a hanger and a nut. The hanging rod is vertically fixed below the roof surface through the expansion head. The main keel is fixed to the lower end of the hanging rod through the hanger or two upper and lower nuts. The hanging members are arranged along the direction of the main keel and the spacing between the hanging members is not more than 800 mm.

[0008] Furthermore, the plurality of main keels are arranged in parallel and the distance between two adjacent main keels is no more than 800 mm.

[0009] Furthermore, the side keels include wall side keels and top side keels. The wall side keels are fixed to the wall by means of Meigu nails with their openings facing the secondary keels. The top side keels are fixed to the roof surface by means of Meigu nails with their openings facing the secondary keels. The spacing of the Meigu nails is set to 300-400 mm.

[0010] Furthermore, the male corner keel is arranged in a long strip shape and its cross section is L-shaped, and openings are arranged on the upper surface and the left side of the male corner keel, and the size of the openings is adapted to be connected with the thickness of the secondary keel.

[0011] Furthermore, the secondary keel includes a first secondary keel and a T-shaped member, the T-shaped member is vertically connected by the second secondary keel and the third secondary keel through a cross keel, and the third secondary keel is arranged in parallel with the male angle keel and the spacing is greater than 150 mm.

[0012] Furthermore, the secondary keel is fixed to the lower end of the main keel by a hanger or a fixing structure adapted to be connected with the buckle of the main keel, and the distance between the secondary keel and the main keel is 300-400 mm.

[0013] Furthermore, the flatness deviation of the lower surface of the ceiling base layer is no more than 2 mm.

[0014] Furthermore, the ceiling surface layer is made of gypsum board and the plane corners of the ceiling surface layer are arranged in an L-shaped structure, and the seams at the plane corners of the ceiling surface layer are arranged on the third secondary keel.

[0015] Compared with the prior art, this application has the following technical effects:

[0016] (1) In the present application, the hanging parts are arranged along the direction of the main keel, with a spacing of no more than 800 mm, which is much smaller than the national standard of 1.2 meters. This is beneficial to increase the number of stress points on the main keel, making the main keel straighter, and preventing the middle part of adjacent stress points from sagging and deforming, thereby ensuring that the risk of cracking of the ceiling is very small and the structure is more stable.

[0017] (2) In the present application, the spacing between the American-fixed nails is much smaller than the national standard, which is conducive to the side keels being tightly fixed on the wall surface and the roof surface, and is conducive to the side keels, especially the wall side keels, being more straight and stable, which further improves the stability of the ceiling base and reduces the risk of cracking of the ceiling.

[0018] (3) In the present application, the "notch connection" technology shown in the right figure is used for the external corner keel at the internal corner, that is, only the internal steel belt is disconnected, and the steel belt facing the outside is not disconnected, but remains connected together, which is beneficial to greatly improve the connection strength at the corner, thereby making the ceiling base structure more stable and the integrity of the plane corner is strengthened, further improving the integrity of the ceiling surface base and reducing the risk of cracking of the ceiling.

[0019] (4) In the present application, the T-shaped component connects the lower surface base of the suspended ceiling, which was originally divided into two parts due to the different arrangement directions of the main keel and the secondary keel, into a whole, which greatly reduces the stress concentration on the lower surface of the suspended ceiling base and greatly improves the crack resistance of the suspended ceiling.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Embodiment 1

The wall D is the original building structure, the bedroom wall D is distributed around the room, and the roof surface F, the original building structure, is located on the top surface of the bedroom, and encloses the bedroom with the wall D and the floor.

[0025] Furthermore, in this embodiment, the ceiling base layer adopts the ceiling decoration material commonly used in the building decoration industry - light steel keel, which is composed of a hanging piece 1, a main keel 2, a secondary keel 4, a side keel 3, and a positive angle keel 5. The light steel keel is pressed with high-quality steel strips, galvanized on the surface, light in weight, high in strength, corrosion-resistant, and very stable in shape and size, which is conducive to the shape and size stability of the ceiling base layer and will not change in shape due to material problems.

[0026] Furthermore, in this embodiment, the hanging component 1 is a structural component of the suspended ceiling, which is used to hang the main keel 2 and transfer the weight of the suspended ceiling structure to the roof surface F above. The hanging component 1 is composed of an expansion head, a hanging rod and a nut. The hanging rod is vertically fixed below the roof surface F through the expansion head, and the main keel 2 is fixed to the lower end of the hanging rod through two upper and lower nuts, that is, the main keel 2 is hung below the roof surface F.

[0027] Preferably, in this embodiment, the main keel 2 is suspended below the roof surface F through the hanging parts 1. Multiple main keels 2 are arranged in parallel and the distance between two adjacent main keels 2 is no more than 800 mm, similar to the beams of a house. They are the main load-bearing components of the ceiling, and transfer the weight of the secondary keel 4 and the ceiling surface to the hanging rod. The hanging parts 1 are arranged along the main keel 2, with a spacing of no more than 800 mm, which is much smaller than the national standard of 1.2 meters, which is conducive to increasing the stress points of the main keel 2, thereby making the main keel 2 more straight, and the middle of the adjacent stress points will not sag and deform, thereby ensuring that the risk of cracking of the ceiling is very small and the structure is more stable.

[0028] Preferably, in this embodiment, the side keel 3 includes a wall side keel 3 and a top side keel 31. The wall side keel 3 is fixed to the wall D by a M8x60 nail with stronger anchoring force and durability, and its opening faces the secondary keel 4. The top side keel 31 is fixed to the roof surface F by a M8x60 nail with stronger anchoring force and durability, and its opening faces the secondary keel 4. The spacing between the above-mentioned nails is set to 300 mm.

[0034] Preferably, in this embodiment, during the construction process, infrared rays are used to constantly detect the height of the lower surface of the secondary keel 4 to ensure that the lower surface of the ceiling base is flat and meets national standards, with a deviation of no more than 2 mm. The locking nuts of each hanging member 1 are tightened to further improve the flatness and structural stability of the lower surface of the ceiling base.

[0035] Preferably, in this embodiment, the ceiling surface layer adopts a gypsum board commonly used in building decoration and renovation, and the gypsum board is fixed to the lower surface of the ceiling with self-tapping screws of specification M3.5x35. At the plane corner of the ceiling surface layer, the gypsum board is processed into an "L shape", and the joint is set on the third auxiliary keel B, avoiding the stress concentration position of conventional process construction, which is conducive to improving the crack resistance of the lower surface of the ceiling.
