Description

Technical Field

[0001] This utility model belongs to the field of building materials technology, and in particular relates to water-resistant paper-faced gypsum board. Background Technology

[0002] Paper-faced gypsum board is a common building material. It consists of two layers of thick paper sandwiching a layer of gypsum. It uses building gypsum as the main raw material, with appropriate additives and fibers mixed in as the core, and special paper as the facing. It is mainly used for interior partition walls and ceilings in buildings.

[0003] When gypsum board is used to assemble partition walls, a waterproof layer is usually installed on the surface of the gypsum board to prevent moisture from entering the interior of the gypsum board and affecting its service life and performance. However, there will be certain gaps between adjacent gypsum boards in the assembled wall, and a small amount of moisture can still enter the gypsum board and affect it. Utility Model Content

[0004] This utility model addresses the problem in existing technologies where gaps exist between adjacent gypsum boards assembled into walls, allowing small amounts of moisture to still seep into the gypsum boards and affect their performance. The following technical solution is proposed:

[0005] Water-resistant paper-faced gypsum board includes: a base body, on both sides of which are provided with placement grooves, and a closed soft layer is provided inside one of the placement grooves. Multiple limiting components are provided inside the closed soft layer. Each limiting component includes a mounting base and two support blocks. The support blocks are rotatably inserted into the mounting base, and a torsion spring is provided between the support blocks and the mounting base. After the support blocks are deflected, they are inserted into the placement groove of the other base body.

[0006] As a preferred embodiment of the above technical solution, the limiting component further includes a pushing block, which contacts two support blocks, and a contact piece is provided at the other end of the pushing block.

[0007] As a preferred embodiment of the above technical solution, the surface of the contact position between the pushing block and the supporting block is arc-shaped, and the range between the pushing block and the supporting block is 10-45 degrees.

[0008] As a preferred embodiment of the above technical solution, a waterproof layer is provided on both sides of the base body, and the waterproof layer is a waterproof polymer material.

[0009] The beneficial effects of this utility model are as follows:

[0010] The sealing layer is inserted into the corresponding groove of the base layer and deforms due to compression. The sealing layer fills the gaps between the gypsum boards, thereby blocking moisture and preventing it from affecting the gypsum boards. The tight and properly treated gypsum board joints can effectively prevent sound from propagating through the gaps, thereby improving the sound insulation performance of the partition wall. In addition, the set limiting components can increase the connection strength between adjacent gypsum boards, which can significantly improve the overall rigidity and stability of the gypsum board partition wall and, to a certain extent, prevent the partition wall from shifting or being damaged by external forces.

[0016] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0017] Figures 1-4 The water-resistant paper-faced gypsum board includes: a base body 10, on both sides of which are provided placement grooves 11. A closed soft layer 20 is provided inside one of the placement grooves 11. Multiple limiting components are provided inside the closed soft layer 20. The limiting components include a mounting base 31 and two support blocks 32. The support blocks 32 are rotatably inserted into the mounting base 31, and a torsion spring is provided between the support blocks 32 and the mounting base 31. The two ends of the torsion spring are fixedly connected to the support blocks 32 and the mounting base 31 respectively. After the support blocks 32 are deflected, they are inserted into the placement groove 11 of the other base body 10.

[0018] The sealing soft layer 20 is inserted into the placement groove 11 of the corresponding base body 10 and deformed due to compression. The sealing soft layer 20 fills the gap between the gypsum boards, thereby blocking water vapor and preventing water vapor from entering and affecting the gypsum boards. In addition, the tight and properly treated gypsum board joints can effectively prevent sound from passing through the gaps, thereby improving the sound insulation performance of the partition wall.

[0019] Figures 2-4 In the middle, the limiting component also includes a pushing block 33, which contacts two support blocks 32, and a contact piece 34 is provided at the other end of the pushing block 33.

[0020] The contact surface between the push block 33 and the support block 32 is arc-shaped, and the range between the push block 33 and the support block 32 is 10-45 degrees.

[0021] The contact piece 34 contacts the surface of the placement groove 11 of the corresponding base body 10. When the contact piece 34 is moved in the opposite direction, it will push the block 33 to move. The surface of the arc-shaped pushing block 33 will push the support block 32 to rotate and insert it into the placement groove 11 of the gypsum board, thereby increasing the connection strength between adjacent gypsum boards. This can significantly improve the overall rigidity and stability of the gypsum board assembled partition wall, and to a certain extent prevent the partition wall from being displaced or damaged by external forces.

[0022] Figures 1-2 In the process, a waterproof layer 40 is provided on both sides of the base body 10, and the waterproof layer 40 is a waterproof polymer material.

[0023] Working principle: When assembling gypsum boards into a wall, one gypsum board is first placed on the mounting frame, and then gypsum boards are installed one after another. When subsequent gypsum boards are installed, the sealing soft layer 20 is inserted into the placement groove 11 of the corresponding base body 10 and deformed due to compression. The sealing soft layer 20 fills the gaps between the gypsum boards, thereby blocking moisture and preventing moisture from entering and affecting the gypsum boards. In addition, the tight and properly treated gypsum board joints can effectively prevent sound from propagating through the gaps, thereby improving the sound insulation performance of the partition wall. During the installation process, the contact piece 34 contacts the surface of the placement groove 11 of the corresponding base body 10. The contact piece 34 is moved in the opposite direction, which moves the pushing block 33. The surface of the arc-shaped pushing block 33 pushes the support block 32 to rotate and insert it into the placement groove 11 of the gypsum board, thereby increasing the connection strength between adjacent gypsum boards. This can significantly improve the overall rigidity and stability of the gypsum board partition wall and, to a certain extent, prevent the partition wall from shifting or being damaged due to external forces.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
