Technical Field

[0001] The utility model relates to the technical field of gypsum board, in particular to a high-density pressure-resistant gypsum board. Background Art

[0002] Gypsum board is a building material, usually used for wall and ceiling decoration and sound insulation. It is a mixture of gypsum and fiber materials and has high density and strength. In construction projects, high-density gypsum board can provide good sound insulation and also has good durability.

[0003] The existing related technologies often have the following defects: when storing the gypsum board before construction, pads are usually placed under the gypsum board to facilitate the later lifting of the gypsum board. However, when the gypsum board is subjected to external force, the gypsum board is easily damaged and broken due to the external pressure.

[0004] Therefore, the utility model provides a high-density pressure-resistant paper-faced gypsum board. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-density pressure-resistant paper-faced gypsum board, including a first base surface layer and a second base surface layer, the first base surface layer and the second base surface layer are both gypsum board layers, and a plurality of ribs are embedded in the interior of the first base surface layer, and the ribs are a "V"-shaped structure.

[0007] The effect achieved by the above components is: by setting the ribs of the "V"-shaped structure, the pressure resistance of the gypsum board when subjected to longitudinal pressure is increased, and the longitudinal bending of the gypsum board is avoided.

[0008] Preferably, a plurality of reserved grooves are evenly formed on the upper surface of the second base surface layer, and the cross-section of the reserved grooves is "V"-shaped.

[0009] The effects achieved by the above components are: the reserved groove of the "V"-shaped structure is set to improve the lateral strength of the gypsum board during use and avoid the lateral bending of the gypsum board.

[0010] Preferably, a woven layer is embedded between the first base surface layer and the second base surface layer, and the woven layer is a nylon layer.

[0011] The effects achieved by the above components are: the braided layer made of nylon layer has excellent strength, especially tensile strength and wear resistance, and the braided layer can avoid serious breakage of the gypsum board during use.

[0012] Preferably, the upper surface of the second base surface layer is coated with a filling layer, and the filling layer is a pulp layer.

[0013] The effect achieved by the above components is: the pulp layer is laid on the reserved groove and the surface of the second base surface layer, thereby improving the flatness of the side of the gypsum board with the reserved groove.

[0014] Preferably, a waterproof layer is glued to the upper surface of the filling layer, and the waterproof layer is a polyurethane layer.

[0015] The effects achieved by the above components are: the waterproof layer made of polyurethane layer is a commonly used waterproof polymer material, has good elasticity and water resistance, and is used as a waterproof layer to improve the waterproof effect of the gypsum board during use.

[0016] Preferably, a plurality of reserved holes are evenly formed on the side walls of the ribs.

[0017] The effect achieved by the above components is that by setting the reserved holes opened on the sides of the ribs, the material for making the gypsum board can be filled inside the reserved holes, thereby improving the stability of the ribs fixed inside the first base surface layer.

[0018] Preferably, the side walls of the ribs are evenly and fixedly connected with a plurality of convex strips.

[0019] The effect achieved by the above-mentioned components is that by providing the convex strips, the friction between the ribs and the inside of the first base surface layer is increased when the ribs are pulled, and the use strength of the ribs is further improved.

[0020] Preferably, the convex strip is a "V"-shaped structure.

[0021] The effect achieved by the above components is that the convex strips of the "V"-shaped structure improve the tightness of the contact between the ribs.

[0022] In summary:

[0023] In the utility model, during the actual use of the gypsum board, by providing the ribs of the "V"-shaped structure, the pressure resistance of the gypsum board when subjected to longitudinal pressure is increased, and the longitudinal bending of the gypsum board is avoided. The reserved grooves of the "V"-shaped structure are provided to improve the lateral strength of the gypsum board during use, and the lateral bending of the gypsum board is avoided. By providing the above structure, the ribs and the convex strips are staggered, which improves the compression and fracture resistance of the gypsum board during use, improves the use strength of the gypsum board, and thus extends the service life of the gypsum board.

[0030] Reference Figure 1 As shown, the utility model provides a technical solution: a high-density pressure-resistant paper-faced gypsum board, comprising a first base surface layer 1 and a second base surface layer 4.

[0031] The following is a detailed description of its overall specific settings and functions.

[0032] Reference Figure 1-Figure 3 As shown, in this embodiment: the first base surface layer 1 and the second base surface layer 4 are both gypsum board layers, and a plurality of ribs 7 are embedded inside the first base surface layer 1, and the ribs 7 are of a "V"-shaped structure. By providing the ribs 7 of the "V"-shaped structure, the pressure resistance of the gypsum board when subjected to longitudinal pressure is increased, and the longitudinal bending of the gypsum board is avoided. A plurality of reserved grooves 6 are evenly provided on the upper surface of the second base surface layer 4, and the cross-section of the reserved grooves 6 is of a "V" shape. The reserved grooves 6 of the "V"-shaped structure are provided to improve the lateral use strength of the gypsum board during use, and avoid the lateral bending of the gypsum board. A braided layer 3 is embedded between the first base surface layer 1 and the second base surface layer 4, and the braided layer 3 is a nylon layer. The braided layer 3 made of the nylon layer has excellent strength, especially tensile strength and wear resistance. The braided layer 3 is made to avoid serious breakage of the gypsum board during use.

[0033] The upper surface of the second base surface layer 4 is coated with a filling layer 5, which is a pulp layer. The pulp layer is laid on the reserved groove 6 and the surface of the second base surface layer 4, which improves the flatness of the side of the gypsum board with the reserved groove 6. The upper surface of the filling layer 5 is glued with a waterproof layer 2, which is a polyurethane layer. The waterproof layer 2 made of a polyurethane layer is a commonly used waterproof polymer material with good elasticity and water resistance. It is used as a waterproof layer 2 to improve the waterproof effect of the gypsum board during use.

[0034] Reference Figure 3-Figure 5 As shown, specifically, the side wall of the rib 7 is evenly provided with a plurality of reserved holes 8. By providing the reserved holes 8 provided on the side of the rib 7, the material for making the gypsum board can be filled inside the reserved holes 8, thereby improving the stability of the rib 7 fixed inside the first base surface layer 1. The side wall of the rib 7 is evenly and fixedly connected with a plurality of convex strips 9. By providing the convex strips 9, the friction between the rib 7 and the inside of the first base surface layer 1 is increased when the rib 7 is pulled, thereby further improving the use strength of the rib 7. The convex strips 9 are of a "V"-shaped structure. The convex strips 9 of the "V"-shaped structure improve the tightness of the contact with the rib 7.

[0035] Working principle: In the actual use of the gypsum board, by setting the ribs 7 of the "V"-shaped structure, the pressure resistance effect of the gypsum board when subjected to longitudinal pressure is increased, and the longitudinal bending of the gypsum board is avoided. The reserved groove 6 of the "V"-shaped structure is set to improve the lateral use strength of the gypsum board during use, and the lateral bending of the gypsum board is avoided. The woven layer 3 made of nylon layer has excellent strength, especially tensile strength and wear resistance. The woven layer 3 is made to further avoid serious fractures during the use of the gypsum board. The pulp layer is laid on the surface of the reserved groove 6 and the second base layer 4, which improves the flatness of the gypsum board on the side where the reserved groove 6 is opened. The waterproof layer 2 made of the polyurethane layer is a commonly used waterproof The water-soluble polymer material has good elasticity and water resistance. It is used as the waterproof layer 2 to improve the waterproof effect of the gypsum board during use. By setting the reserved hole 8 opened on the side of the rib 7, the material for making the gypsum board can be filled in the reserved hole 8, thereby improving the stability of the rib 7 fixed inside the first base layer 1. By setting the convex strip 9, the friction between the rib 7 and the inside of the first base layer 1 is increased when the rib 7 is twitched, and the use strength of the rib 7 is further improved. The convex strip 9 with a "V"-shaped structure improves the tightness between the rib 7 and the rib 7. By setting the above structure, the rib 7 and the convex strip 9 are staggered, which improves the compression and fracture resistance of the gypsum board during use, improves the use strength of the gypsum board, and thus extends the service life of the gypsum board.
