Description

Technical Field

[0001] The present application relates to the technical field of building decoration, and in particular to an anti-cracking ceiling gypsum board. Background Art

[0002] Gypsum board is the most widely used new type of ceiling decoration material on the market. It has good decorative effect and good sound absorption performance, and its price is low compared to other roof decoration materials. A keel frame is often set on the back of the gypsum board, and the keel frame can serve as the basis for installing and fixing the gypsum board. For example, the Chinese patent with publication number CN219794372U is named a gypsum board assembled ceiling, and the Chinese patent with publication number CN208965851U is named a gypsum board keel frame connection structure.

[0003] However, in the ceiling decoration process, due to the lack of flatness and structural instability after the installation of the keel frame, the long-term stress imbalance of the gypsum board will eventually cause the gypsum board to deform and crack, especially the corners of the gypsum board (that is, the joints between two gypsum boards) are prone to cracking. Utility Model Content

[0004] In order to improve the defect that the corners of the gypsum board are prone to cracking, the present application provides an anti-cracking ceiling gypsum board.

[0005] The present application provides an anti-cracking ceiling gypsum board, which adopts the following technical solutions:

[0006] A crack-resistant ceiling gypsum board comprises an L-shaped gypsum board and a keel frame arranged on the back of the gypsum board, wherein the keel frame is distributed along the edge and center line of the gypsum board, an anti-cracking component is arranged between the gypsum board and the keel frame, and the gypsum board, the anti-cracking component and the keel frame are connected and fixed by a connecting component.

[0007] By adopting the above technical solution, the L-shaped gypsum board is a whole gypsum board with higher structural strength. Secondly, the anti-cracking component is arranged between the gypsum board and the keel frame, and the three are connected in sequence through the connecting component. The anti-cracking component can improve the strength of the gypsum board. When affected by the insufficient flatness and unstable structure after the installation of the keel frame, the gypsum board has stronger bearing capacity, so that the gypsum board is less likely to crack at the corners.

[0008] Optionally, the anti-cracking component includes an iron sheet, which is arranged between the gypsum board and the keel frame. The iron sheet is densely covered with holes, and burrs are formed around the holes on the side of the iron sheet facing the gypsum board; under the action of the connecting component, the iron sheet is tightly attached to the back of the gypsum board, and the burrs penetrate into the gypsum board.

[0009] By adopting the above technical solution, the connecting components connect the gypsum board, iron sheet and keel frame in sequence. Under the action of the connecting components, the iron sheet is tightly attached to the back of the gypsum board, which can improve the overall strength of the gypsum board, and the burrs on the iron sheet penetrate into the gypsum board, which can improve the grip of the iron sheet on the gypsum board, making the connection between the iron sheet and the gypsum board more firmly. Therefore, when affected by the lack of flatness and structural instability after the installation of the keel frame, the gypsum board has higher crack resistance and is less likely to crack.

[0010] Optionally, the holes are evenly distributed along the edge and center line of the iron sheet.

[0011] By adopting the above technical solution, the holes are evenly distributed along the edge and center line of the iron sheet, that is, the burrs are evenly distributed along the edge and center line of the iron sheet. This design makes the gripping force of the iron sheet on the gypsum board more uniform and the connection between the two is more firm.

[0012] Optionally, an adhesive layer is provided on the side of the iron sheet facing the gypsum board.

[0013] By adopting the above technical solution, an adhesive layer is provided for bonding the iron sheet and the gypsum board, so that the connection between the iron sheet and the gypsum board is more firmly established, and the gypsum board is less likely to crack under the action of the iron sheet.

[0014] Optionally, the connecting assembly includes a plurality of screws a, and the screws a are distributed along the edge and center line of the gypsum board, and the gypsum board, the iron sheet and the keel frame are connected and fixed by the screws a.

[0015] By adopting the above technical solution, the keel is distributed along the edge and center line of the gypsum board, which can not only improve the firmness of the connection between the two, but also make the gypsum board bear the force evenly, thus increasing its strength. Screw A is used to connect the gypsum board, iron sheet and keel in sequence.

[0016] Optionally, the keel frame forms a hollow area on the back side of the gypsum board, the hollow area is filled with a patching plate, and the gypsum board, the iron sheet and the patching plate are connected and fixed by screws b.

[0017] By adopting the above technical solution, the hollow area formed between the keel frames is filled with a filling plate, and then the gypsum board, iron sheet and filling plate are connected in sequence by screws b. This can not only compact the adhesive layer to make the iron sheet and the gypsum board adhere more firmly, but also make the anti-cracking ceiling gypsum board better in integrity and more beautiful.

[0018] Optionally, the patch plate is arranged flush with the keel frame.

[0019] By adopting the above technical solution, the filling plate is set flush with the keel frame in order to keep the anti-cracking ceiling gypsum board flat as a whole and more beautiful.

[0020] In summary, this application has the following beneficial technical effects:

[0021] 1. The anti-crack component can improve the structural strength and crack resistance of the gypsum board. Therefore, when the keel frame is not flat enough or the structure is unstable after installation, the gypsum board has a stronger bearing capacity, making it less likely to crack at the corners of the gypsum board.

[0022] 2. The burrs and adhesive layer make the connection between the iron sheet and the gypsum board more firmly, which means that the fixing effect of the iron sheet is better. The iron sheet mainly plays a tear-resistant role in the ceiling gypsum board structure. Therefore, when the ceiling gypsum board structure is affected by the lack of flatness and structural instability after the installation of the keel frame, the gypsum board has higher crack resistance and is less likely to crack.

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] The present application embodiment discloses a crack-proof ceiling gypsum board. Figure 1 The anti-cracking ceiling gypsum board includes a gypsum board 1. The gypsum board 1 is an L-shaped whole gypsum board formed by manual or mechanical cutting, which has better integrity and higher strength. The embodiment of the present application takes the application of the gypsum board 1 to the corner of the ceiling as an example. Of course, it can also be applied to the corner of the wall. The shape of the gypsum board 1 can also be changed to apply it to any position of the ceiling.

[0031] Reference Figure 1and Figure 2 , the side of the gypsum board 1 facing the room is set as the front, and the side facing the floor is set as the back, so a keel frame 2 is set on the back of the gypsum board 1, and the keel frame 2 can serve as the basis for installing and fixing the gypsum board 1. The keel frame 2 can be made of wood or directly made of light steel keel. In the embodiment of this application, wood is taken as an example. The keel frame 2 is divided into several sections, distributed along the edge and center line of the gypsum board 1, and covers the back of the gypsum board 1 more evenly. Since the gypsum board 1 is L-shaped as a whole, the keel frame 2 can form three square hollow areas 5 on the back of the gypsum board 1. The gypsum board 1 and the keel frame 2 are connected by a connecting component 4, which is a plurality of screws a41. During installation, the screws a41 are passed through the gypsum board 1 from the front and then threaded into the keel frame 2 to fix the gypsum board 1 and the keel frame 2 together. To ensure that the keel frame 2 is evenly stressed on the gypsum board 1, the screws a41 are evenly distributed along the edge and center line of the gypsum board 1.

[0032] Reference Figure 2 and Figure 3 During use, in order to reduce the cracking phenomenon at the corners of the gypsum board 1, an anti-crack component 3 can be set between the gypsum board 1 and the keel frame 2. The anti-crack component 3 includes an iron sheet 31 and an adhesive layer 33 arranged on the side of the iron sheet 31 facing the gypsum board 1. The iron sheet 31 is a stainless steel iron sheet that is not easy to rust. The iron sheet 31 is laid along the back of the gypsum board 1 and covers the entire gypsum board 1. Therefore, the iron sheet 31 is also L-shaped and is also obtained by manual or mechanical cutting. The adhesive layer 33 is an epoxy resin adhesive, which is coated on the surface of the iron sheet 31. When the screw a41 passes through the gypsum board 1 from the front and is then threaded into the keel frame 2, the screw a41 will pass through the iron sheet 31, thereby firmly fixing the iron sheet 31 between the gypsum board 1 and the keel frame 2. In this process, the adhesive layer 33 also adheres the iron sheet 31 to the gypsum board 1, thereby improving the tightness and firmness of the connection between the iron sheet 31 and the gypsum board 1. It should be noted here that the stainless steel iron sheet 31 can resist the influence of insufficient flatness and structural instability after the installation of the keel frame in the suspended ceiling gypsum board structure, that is, under the influence of insufficient flatness and structural instability after the installation of the keel frame, the iron sheet 31 is not easy to tear, and the iron sheet 31 has a protective effect on the gypsum board 1, so the suspended ceiling gypsum board structure is not prone to cracking at the corners, thereby achieving the purpose of preventing cracking at the corners of the suspended ceiling gypsum board structure.

[0033] Reference Figure 3 and Figure 4In addition, in order to further make the connection between the iron sheet 31 and the gypsum board 1 more firmly, improve the fixing effect of the iron sheet 31 on the back of the gypsum board 1, and strengthen the anti-cracking effect of the iron sheet 31 in the ceiling gypsum board structure, holes 311 can be densely distributed on the iron sheet 31. The holes 311 are evenly distributed along the edge and center line of the iron sheet 31, and the holes 311 are arranged in two rows along the edge of the iron sheet 31 and are relatively densely arranged, that is, the holes 311 are covered by the keel frame 2. The holes 311 are actually mechanically punched through the iron sheet 31. After mechanical punching, burrs 32 are formed at the holes 311 on the side of the iron sheet 31 facing the gypsum board 1. The length of the burrs 32 is between 1.5 and 2 mm. This ensures that the holes 311 penetrate into the gypsum board 1 and secure the iron sheet 31 without piercing or damaging the gypsum board 1. Since the holes 311 are arranged in two rows along the edge of the iron sheet 31, the securing effect is better than that of a single row. Therefore, under the action of screws a41, the iron sheet 31 is fixed between the gypsum board 1 and the keel 2, while the burrs 32 on the iron sheet 31 penetrate into the gypsum board 1, thereby improving the grip of the iron sheet 31 on the gypsum board 1 and strengthening the connection between the iron sheet 31 and the gypsum board 1. As a result, the ceiling gypsum board structure has higher crack resistance at the corners, making it less susceptible to cracking due to factors such as insufficient flatness and structural instability after the keel is installed.

[0034] Since the holes 311 are evenly distributed along the edge and center line of the iron sheet 31, that is, the burrs 32 are evenly distributed along the edge and center line of the iron sheet 31, the gripping force of the iron sheet 31 on the gypsum board 1 is more uniform, and the connection between the two is more secure. In this way, after the iron sheet 31 is fixed between the gypsum board 1 and the keel frame 2, the overall structure will be more stable. In this way, when affected by various forces of the keel frame, all parts of the iron sheet 31 and the gypsum board 1 can be evenly stressed, and the anti-cracking effect will be better.

[0035] Reference Figure 1 and Figure 2 Each of the three hollow areas 5 on the back of the gypsum board 1 is fitted with a wooden patch plate 6. Once inserted into each hollow area 5, the patch plate 6 is flush with the keel frame 2, enhancing the structural integrity and aesthetics of the suspended gypsum board. The patch plates 6 are secured with screws b7, which penetrate the gypsum board 1 and the metal sheet 31 from the front and then thread into the patch plates 6. During this process, the patch plates 6 cling tightly to the metal sheet 31, compacting the adhesive layer 33 and improving the adhesion between the metal sheet 31 and the gypsum board 1, making the connection more secure.

[0036] In another embodiment of the present application, referring to Figure 5Both ends of the L-shaped ceiling gypsum board structure can be set as an oblique structure (that is, the gypsum board 1, the iron sheet 31 and the keel frame 2 are inclined or arranged at an angle at this location). In this way, when the ceiling gypsum board structure is affected by the force of the keel frame, especially when the force of the keel frame toward the inclined structure is affected, the inclined structure can disperse and buffer the force of the keel frame, thereby preventing the two ends of the L-shaped gypsum board structure from cracking linearly.

[0037] The implementation principle of the anti-cracking ceiling gypsum board of the present application is: under the action of the screw a41, the iron sheet 31 is fixed between the gypsum board 1 and the keel frame 2, and the burrs 32 on the iron sheet 31 penetrate into the gypsum board 1, thereby improving the gripping force of the iron sheet 31 on the gypsum board 1, making the connection between the iron sheet 31 and the gypsum board 1 more firmly, and in this process, the adhesive layer 33 also adheres the iron sheet 31 and the gypsum board 1 together, improving the tightness and firmness of the connection between the iron sheet 31 and the gypsum board 1, so that when the ceiling gypsum board structure is affected by the insufficient flatness and structural instability after the installation of the keel frame, the ceiling gypsum board structure has higher crack resistance at the corners and is less likely to crack.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
