[0002] Lightweight gypsum board is widely used in various buildings such as residences, office buildings, shops, hotels, and industrial plants for wall cladding, ceilings, sound-absorbing panels, and other decorative panels. Since the main component of lightweight gypsum board is gypsum, it expands and contracts due to moisture and temperature changes over time. To reduce the risk of misalignment at the joints caused by expansion and contraction after installation, a lightweight gypsum board joint treatment device has been designed. This device, with a pre-existing space between paper-faced gypsum boards, adds lightweight steel plates, long-handled support nails, and short-handled support nails. This allows the expansion direction of the paper-faced gypsum board to be guided during expansion and contraction, thus protecting the edges of the gypsum board after installation and reducing the risk of misalignment at the joints due to expansion and contraction.

[0025] Figure 1-7 This invention illustrates a lightweight gypsum board joint treatment device according to an embodiment of the present invention, comprising: two lightweight steel keels 1; positioning point gypsum boards 2 are bolted to the bottom of each of the two lightweight steel keels 1, and paper-faced gypsum boards 3 are bolted to the bottom of each positioning point gypsum board 2; a lightweight steel plate 4 is disposed between the two lightweight steel keels 1; multiple short circular grooves 5 are formed on the top of the lightweight steel plate 4; two long circular grooves 6 are formed on the surface of the lightweight steel plate 4; edging strips 7 are fixedly connected to both sides of the paper-faced gypsum board 3; two long-handled support nails 8 are welded to the top of the edging strips 7; and threaded ends are welded to the top of the long-handled support nails 8. The top of the gypsum board 2 on both sides of the head 9 and the positioning point 9 are fixedly connected with multiple short-handled support nails 10. The surface of the threaded end 9 is slidably connected to the inner cavity of the elongated groove 6.

The surface of the threaded end 9 is threadedly connected with a limiting piece 11. The limiting piece 11 is located above the lightweight steel plate 4. By setting the limiting piece 11, the threaded end 9 can obtain a limiting connection force between itself and the lightweight steel plate 4 during the sliding process in the inner cavity of the elongated groove 6, which can give the paper-faced gypsum board 3 a better guiding effect. The top of the lightweight steel keel 1 is provided with a top plate 13. Example 2

[0026] Figure 1-7This invention illustrates a lightweight gypsum board joint treatment device according to an embodiment of the present invention, comprising: two light steel keels 1; positioning point gypsum boards 2 are bolted to the bottom of each of the two light steel keels 1, and paper-faced gypsum boards 3 are bolted to the bottom of each positioning point gypsum board 2; a lightweight steel plate 4 is disposed between the two light steel keels 1; multiple short circular grooves 5 are formed on the top of the lightweight steel plate 4; two long circular grooves 6 are formed on the surface of the lightweight steel plate 4; edging strips 7 are fixedly connected to the left and right sides of the paper-faced gypsum board 3; two long-handled support nails 8 are welded to the top of the edging strips 7; and threaded ends 9 are welded to the top of the long-handled support nails 8. Multiple short-handled support nails 10 are fixedly connected to the top of both sides of the positioning gypsum board 2. Rectangular grooves 12 are opened on both sides of the lightweight steel plate 4. The surface of the lightweight steel keel 1 is fixedly connected to the inner cavity of the rectangular groove 12. By setting the rectangular groove 12, the connection points between the lightweight steel plate 4 and the lightweight steel keel 1 can be increased when the lightweight steel plate 4 is fixed between the two lightweight steel keels 1, which can make the lightweight steel plate 4 and the lightweight steel keel 1 more secure after fixing. The top of the two lightweight steel keels 1 are fixedly connected to the threaded rods 14 by bolts. The lightweight steel keel 1 is fixedly connected to the bottom of the top plate 13 by the threaded rods 14.

[0027] Working principle: When using this utility model, the user lifts and fixes the light steel keel 1 using the threaded rod 14. Then, the positioning point gypsum board 2 and paper-faced gypsum board 3 are fixedly connected to the bottom of the light steel keel 1 using bolts. Next, the edge banding strip 7 is fixedly connected to both sides of the paper-faced gypsum board 3 together with the long-handled support nail 8, and the short-handled support nail 10 is inserted into the top of both sides of the positioning point gypsum board 2. Then, the light steel plate 4 is fixedly connected between the two light steel keels 1, and the threaded end 9 and the short-handled support nail 10 are slidably connected to the inner cavity of the long round groove 6 and the short round groove 5, respectively. This guides the direction of expansion and extension of the positioning point gypsum board 2 and the paper-faced gypsum board 3. After the gypsum board is installed, the edge banding is used to protect the gypsum board, so as to reduce the squeezing and skewing of the gypsum board joints due to expansion and contraction.

[0028] In summary, this lightweight gypsum board joint treatment device achieves the purpose of edge protection for gypsum board after installation by fixing the lightweight steel plate 4 between two lightweight steel keels 1 and ensuring that the threaded end 9 and the short shank support nail 10 are slidably connected to the inner cavities of the long round groove 6 and the short round groove 5, respectively. This reduces the risk of gypsum board joints being squeezed and skewed due to expansion and contraction.
