Description

Technical Field

[0001] This utility model relates to the field of gypsum board technology, and more specifically, to a novel waterproof gypsum board. Background Technology

[0002] In the field of architectural decoration, gypsum board is widely used in various construction projects due to its excellent processing performance, superior fire resistance and sound insulation, and relatively low cost. Whether in residential, commercial, or public buildings, gypsum board plays a vital role. It can be used not only to create various shapes of ceilings and partitions, but also as a decorative material for walls and ceilings, greatly enriching the design and construction methods of architectural decoration.

[0003] However, traditional gypsum board is prone to water absorption and deformation in humid environments, even leading to structural damage. Furthermore, when installing waterproof gypsum board, adjacent boards are typically joined together using adhesive. However, after installation, the gaps between adjacent boards are often quite large, making them susceptible to water penetration and corrosion. This can cause water to seep into the gypsum board, affecting its structural stability and lifespan. Once water enters the gypsum board, it not only reduces its fire resistance and sound insulation but can also lead to mold growth, seriously impacting indoor health and safety.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a new type of waterproof gypsum board to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A novel waterproof gypsum board includes a gypsum board body, which comprises a base layer, a fiberglass mesh layer, and a polyester amine film layer. An edge strip is fixedly connected to the outer side of the gypsum board body. One side of the gypsum board body is provided with an insertion plate, and the other side is provided with an insertion groove. The insertion plate and the insertion groove are matched. One end of the insertion plate is provided with an opening, and a locking block is provided inside the opening. One side of the insertion groove is provided with a locking slot, and the locking block and the locking slot are matched.

[0008] Furthermore, in order to drive the block to move, a threaded rod is provided on one side of the block, and a slider is threadedly connected to the threaded rod. The slider is connected to the block, and a driven bevel gear is fixedly connected to the threaded rod. The driven bevel gear meshes with the driving bevel gear, and the driving bevel gear is connected to the rotating shaft. One end of the rotating shaft is connected to the rotating plate.

[0009] Furthermore, in order to fix the rotating shaft, the rotating shaft is connected to the fixed plate through bearings, the fixed plate is connected to the plug plate, and both ends of the threaded rod are connected to the plug plate through bearings.

[0010] Furthermore, in order to position the connector plate and prevent it from moving excessively inside the connector slot, a groove is provided at one end of the connector plate, and a telescopic spring is provided inside the groove. One end of the telescopic spring is connected to the connector plate, and the other end is connected to the positioning post.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] According to an embodiment of the present invention, a novel waterproof gypsum board is provided.

[0027] Example 1

[0028] like Figures 1-4As shown, the novel waterproof gypsum board according to an embodiment of this utility model includes a gypsum board body 1, which includes a base layer 2, a fiberglass mesh layer 3, and a polyesteramine film layer 4. The fiberglass mesh has good tensile strength and heat resistance. Embedding it on the outside of the base layer 2 of the gypsum board can effectively disperse and absorb external impact forces, preventing cracks or breaks in the board during use. Polyesteramine is a high-performance waterproof material with good waterproof, moisture-proof, and corrosion-resistant properties. By covering the fiberglass mesh layer 3 with the polyesteramine film layer 4, moisture can be effectively prevented from penetrating into the interior of the gypsum board, thereby extending its service life. The fiberglass mesh layer 3 is located on the outside of the base layer 2, and the polyesteramine film layer 4 is located on the outside of the fiberglass mesh layer 3. An edge banding strip 5 is fixedly connected to the outside of the gypsum board body 1 to prevent moisture from entering the interior of the gypsum board through the edge. One side of the gypsum board body 1 has an insertion plate 6, and the other side has an insertion groove 7. The insertion plate 6 matches the insertion groove 7. One end of the insertion plate 6 has an opening 8, and a locking block 9 is provided inside the opening 8. One side of the insertion groove 7 has... There is a slot 10, and a block 9 matches the slot 10. A threaded rod 11 is provided on one side of the block 9. A slider 12 is threadedly connected to the threaded rod 11. The slider 12 is connected to the block 9. A driven bevel gear 13 is fixedly connected to the threaded rod 11. The driven bevel gear 13 meshes with the driving bevel gear 14. The driving bevel gear 14 is connected to the rotating shaft 15. One end of the rotating shaft 15 is connected to the rotating plate 16. The fixed plate 17 is connected to the plug plate 6. Both ends of the threaded rod 11 are connected to the plug plate 6 through bearings. A connecting groove 23 is provided on one side of the opening 8. The block 9 matches the connecting groove 23.

[0029] like Figures 1-5 As shown, one end of the plug-in plate 6 is provided with a groove 18, and a telescopic spring 19 is provided inside the groove 18. One end of the telescopic spring 19 is connected to the plug-in plate 6, and the other end is connected to the positioning post 20. The plug-in groove 7 is provided with a positioning groove 21, and the positioning post 20 matches the positioning groove 21. A fixing hole 22 is provided on one side of the positioning groove 21. When it is necessary to replace the damaged gypsum board body 1, the positioning post 20 can be moved into the groove 18 by inserting the board body, thereby facilitating the replacement of the gypsum board body 1.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In practical applications, a fiberglass mesh layer 3 is set on the outside of the base layer 2, and a polyester amine film layer 4 is covered on it. The fiberglass mesh increases the overall strength and impact resistance of the board, while the polyester amine film provides excellent waterproofness and durability. When two gypsum boards need to be assembled, the interlocking plate 6 on one side of one gypsum board can be slidably installed inside the interlocking groove 7 on the other side of the gypsum board. During the movement of the interlocking plate 6, the telescopic spring 19 is in a compressed state. When the positioning post 20 moves to the positioning groove 21, the positioning post 20 will automatically pop out under the action of the telescopic spring 19 and match the positioning groove 21 inside the interlocking groove 7. This design not only prevents the plug-in plate 11 from being damaged or unstable due to over-insertion, but also allows for the rotation of the rotating plate 16, which drives the rotating shaft 15 and the driving bevel gear 14 to rotate. The rotation of the driving bevel gear 14 drives the driven bevel gear 13 and the threaded rod 11 to rotate. The rotation of the threaded rod 11 drives the slider 12 and the locking block 9 to move, so that one end of the locking block 9 passes through the connecting groove 23 and is placed inside the locking groove 10. This further fixes the plug-in plate 6, preventing it from loosening or falling off during use. Furthermore, when a plasterboard is damaged, the rotating plate 16 can be rotated in the opposite direction to move the locking block 9 away from the locking groove 10. By inserting the plate body through the fixing hole 22 and moving the positioning post 20, the plug-in plate 6 can be removed from the plug groove 7. This convenient disassembly method allows for the quick replacement of damaged waterproof plasterboard, reducing maintenance time and costs.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
