[0023] Newly built buildings have very serious indoor moisture due to the high moisture content of building or decoration materials, such as concrete, blocks, plaster, etc. The moisture content is as high as 50% or more. Especially in the lower floors and basements where the ground is in contact with the outdoor ground, the moisture is already very high. If it encounters the rainy season, the problem is even more serious. As soon as the interior decoration is completed, it is put into use. Due to the generally poor ventilation, air conditioning systems are generally used indoors, and the ventilation capacity of air conditioners is very poor, generally only about 0.5 times / hour, resulting in the internal moisture enclosed by the ceiling or partition wall cannot be eliminated for a long time, causing the ceiling or partition wall to deform, crack, and even mold.

[0024] At present, indoor ceilings and lightweight partitions generally use light steel keel gypsum board structure. Gypsum board is a wall material made of building gypsum as the main raw material, mixed with fiber, admixture and appropriate amount of lightweight filler, mixed with water to form a slurry, and pasted with special face paper on both sides and then dried. Ordinary gypsum board is mainly used for indoor walls, partitions and ceilings. When gypsum board is damp, it is easy to cause the face paper to mold, and excessive water absorption causes the board core and the face paper to separate, or cause the wall or ceiling to deform, which seriously affects the use function. Moreover, light steel keels and self-tapping screws are permeable components. After the gypsum board and light steel keels are fixed with self-tapping screws, the enclosed moisture further penetrates into the gypsum board through the light steel keel and self-tapping screws, further aggravating the deformation and damage of the gypsum board.

[0025] In the related art, the gypsum board structure includes a keel, a gypsum board and a fastener, wherein the keel is provided with a mounting hole, the gypsum board is provided with a connecting hole on the side facing the keel, and the fastener is provided with the connecting hole and the mounting hole in sequence to connect the gypsum board to the keel. However, since the keel is a water-permeable component, external moisture can easily penetrate into the connecting hole of the gypsum board through the keel, causing the gypsum board to absorb water and deform, which is not conducive to ensuring the service life of the gypsum board.

[0026] In order to solve the above problems, the utility model proposes a gypsum board moisture-proof structure 10, which aims to prevent the gypsum board 3 from being deformed by moisture and ensure the service life of the gypsum board 3.

[0027] Reference Figure 1 In one embodiment of the utility model, the gypsum board moisture-proof structure 10 includes a keel 1, a gypsum board 3 and a fastener 5. The outer surface of the keel 1 is covered with a first waterproof layer 61, and is provided with a mounting hole 11 that penetrates the keel 1 and the first waterproof layer 61; the gypsum board 3 is penetrated with a connecting hole 31 on the side facing the waterproof layer; the fastener 5 is sequentially penetrated through the connecting hole 31 and the mounting hole 11 to connect the gypsum board 3 to the keel 1, and make the opening edge of the connecting hole 31 facing the keel 1 abut against the first waterproof layer 61.

[0028] Among them, the gypsum board moisture-proof structure 10 of this solution is suitable for indoor walls, partitions or ceilings, etc. All technical solutions using the gypsum board moisture-proof structure 10 fall within the protection scope of this application.

[0029] The keel 1 serves as a supporting frame for the gypsum board moisture-proof structure 10 and is responsible for carrying and fixing various decorative surface materials 7, such as gypsum board, mineral wool board, metal plate, ceramic tile, wood veneer, etc., to ensure that these materials can be firmly installed on the wall, ceiling or floor to form a flat and solid surface.

It is worth noting that since the outer surface of the keel 1 is covered with the first waterproof layer 61, and the opening edge of the connecting hole 31 of the gypsum board 3 facing the keel 1 abuts against the first waterproof layer 61, it is prevented that external moisture further penetrates into the connecting hole 31 of the gypsum board 3 through the keel 1, which is conducive to preventing the gypsum board 3 from being deformed by moisture and ensuring the service life of the gypsum board 3.

[0031] Optionally, the keel 1 is made of steel, galvanized steel or stainless steel, with a width range of 50-60 mm, a height range of 19-27 mm, and a thickness range of 0.5-0.6 mm.

[0034] Optionally, the material of the second waterproof layer 62 can be polyurea coating.

[0036] In this embodiment, one side of the head 53 of the fastener 5 is filled and sealed by the third waterproof layer 63, thereby preventing external moisture from penetrating into the connecting hole 31 and further penetrating through the connecting portion 51 of the fastener 5, which is beneficial to further avoid moisture-proof deformation of the gypsum board 3 and enhance the waterproof effect of the gypsum board 3.

[0037] Reference Figure 1 In one embodiment of the present utility model, the material of the third waterproof layer 63 is waterproof putty.

[0038] In this embodiment, the waterproof putty can maintain good stability in a humid environment, and can maintain structural integrity even if it is immersed in water for a long time, without peeling, cracking or falling off, and its bonding strength is usually above 0.50 MPa under standard conditions. By using the waterproof putty as the third waterproof layer 63, it is helpful to further ensure the service life of the gypsum board 3.

[0041] In this embodiment, the fastener 5 is threadedly connected to the mounting hole 11 of the keel 1 through the connecting portion 51, which is conducive to achieving the installation stability of the fastener 5 and the keel 1, and preventing the fastener 5 from falling off due to moisture, thereby ensuring the connection stability between the gypsum board 3 and the keel 1, and further improving the service life of the gypsum board 3.

[0043] The driving groove is in the shape of a cross groove, and the end of the driving shaft of the driving member may be a cross drill bit, which is inserted into the cross groove, thereby driving the fastener 5 to rotate.

[0044] In this embodiment, the fastener 5 is driven to rotate by the driving member, so that the fastener 5 can be quickly inserted into the connecting hole 31 and the mounting hole 11, which is beneficial to improving production efficiency and further ensuring the connection stability between the gypsum board 3 and the keel 1.

[0045] Optionally, the fastener 5 is a countersunk self-tapping screw with a length ranging from M3.5 to M4.8 and a length ranging from 16 mm to 50 mm.

[0046] Reference Figure 1 In one embodiment of the present invention, the material of the first waterproof layer 61 is a polyurea coating.

[0047] In this embodiment, polyurea is a new type of solvent-free, pollution-free green paint, which can be sprayed on any curved surface, inclined surface and vertical surface without sagging, insensitive to water and moisture, and unaffected by ambient temperature and humidity during construction; 100% solid content, does not contain any volatile organic matter, and is environmentally friendly; has excellent physical and chemical properties, such as tensile strength, elongation, flexibility, wear resistance, aging resistance, corrosion resistance, and good thermal stability, and can be used for a long time at 120°C. Therefore, by coating the outer surface of the keel 1 with a polyurea coating, it is beneficial to further ensure the service life of the gypsum board 3.

[0048] Optionally, the polyurea coating is formed by spraying or brushing.

[0049] Reference Figure 1 In one embodiment of the present invention, the thickness of the polyurea coating ranges from 0.5 mm to 2 mm.

[0052] In this embodiment, a fourth waterproof layer 64 is provided on the side of the connection hole 31 away from the keel 1. The fourth waterproof layer 64 can block moisture from entering the side of the connection hole 31 away from the keel 1, which is beneficial to prevent the gypsum board 3 from being deformed by moisture and ensure the service life of the gypsum board 3.
