Description

Technical Field

[0001] This utility model relates to the field of gypsum board technology, specifically to a high-strength, crack-resistant paper-faced gypsum board. Background Technology

[0002] Gypsum board is a material made primarily from building gypsum. It typically consists of a gypsum core and facing paper on both sides. It is a lightweight, high-strength, thin, easy-to-process building material with good sound insulation, heat insulation, and fire resistance properties. It is one of the new lightweight building materials that is currently being developed.

[0003] The modern building decoration market has increasingly higher performance requirements for gypsum board. Beyond basic properties like lightweight, fire resistance, and sound insulation, it demands higher strength and better crack resistance to ensure both aesthetic appeal and building quality. Easier installation is also desired. Developing high-strength, crack-resistant paper-faced gypsum board can meet the market's demand for high-quality building decoration materials and enhance product competitiveness.

[0004] In traditional gypsum board ceiling installation, the joints between gypsum boards are mostly glued together with adhesive. However, adhesive contains some ingredients that are harmful to the human body. A large amount of adhesive is required during the installation of gypsum boards, which makes the indoor environment very harsh. Moreover, after installation, some adhesive residue will remain at the joints of the gypsum boards. Whether wiped or not, it will affect the appearance of the gypsum boards.

[0005] Therefore, it is particularly important to improve existing high-strength crack-resistant paper-faced gypsum boards and design a new type of high-strength crack-resistant paper-faced gypsum board to solve the above-mentioned technical defects and improve the overall practicality of high-strength crack-resistant paper-faced gypsum boards.

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

[0026] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0027] A high-strength, crack-resistant gypsum board includes a board body 1. An annular block 2 is fixedly connected to the middle of the left end of the board body 1. Insert blocks 3 are symmetrically fixedly connected to the left end of the board body 1 on both sides of the annular block 2. Dovetail grooves 4 are symmetrically formed on both sides of the insert blocks 3. An annular groove 5 is formed at the middle of the right end of the board body 1, corresponding to the position of the annular block 2. Rubber particles are provided on the inner sidewall of the annular groove 5. A slot 6 is formed at the right end of the board body 1, corresponding to the position of the insert blocks 3. A dovetail block 7 is fixedly connected to the inner sidewall of the slot 6, corresponding to the position of the dovetail groove 4. Through the cooperation of the annular block 2 and the annular groove 5, and the cooperation of the insert blocks 3 and the slot 6, and the dovetail groove 4 and the dovetail block 7, a tight connection between the boards 1 is achieved. The rubber particles on the inner sidewall of the annular groove 5 enhance the stability and sealing of the connection. During installation, the annular block 2 and the insert blocks 3 of one board body 1 are aligned with the annular groove 5 and the slot 6 of another board body 1 and inserted until the dovetail groove 4 and the dovetail block 7 are fully engaged, thus completing the connection.

[0028] Furthermore, in this embodiment, a fixing plate 8 is fixedly connected to the front of the plate 1, and a protrusion 9 is fixedly connected to the outside of the fixing plate 8. A connecting block 10 is fixedly connected to the end of the protrusion 9 away from the fixing plate 8. The connecting block 10 has a C-shaped structure design and is a rubber connecting block. A placement groove is opened on the side of the plate 1 away from the fixing plate 8. A connecting box 11 is fixedly connected inside the placement groove. A connecting groove 12 is opened inside the connecting box 11 at the position corresponding to the connecting block 10. An extension edge is symmetrically fixedly connected to one end of the connecting groove 12. By aligning the sides of the two sets of plates 1, the connecting block 10 is inserted into the inside of the connecting groove 12. Then, one set of plates 1 is slid. At this time, the connecting block 10 moves axially along the connecting groove 12. Finally, the two ends of the connecting block 10 are blocked by the extension edge, and the horizontal splicing between the two sets of plates 1 is completed.

[0029] Furthermore, in this embodiment, a drainage groove 13 is provided on the top of the plate 1. The drainage groove 13 has a straight structure in the middle and an eight-shaped structure on both sides. By installing the plate 1 with the top facing down on the ceiling, when the plate 1 produces water droplets due to high humidity in the air, the eight-shaped structure helps to guide the accumulated water to flow to the middle more quickly, then gather into water droplets, and then fall off due to gravity.

[0030] Furthermore, in this embodiment, multiple sets of ventilation holes 14 are provided at the bottom of the plate 1. The multiple sets of ventilation holes 14 are distributed at equal intervals. The design of the ventilation holes 14 is to enhance the ventilation performance at the bottom of the plate 1, which helps to maintain the circulation and dryness of indoor air. The equal interval distribution ensures the uniformity of ventilation.

[0031] Furthermore, in this embodiment, the panel 1 is composed of a reinforcing layer 101, a sound insulation layer 102, and a purification layer 103. The reinforcing layer 101 is located at the top of the inner side of the panel 1, the sound insulation layer 102 is located at the bottom of the reinforcing layer 101, and the purification layer 103 is located at the bottom of the sound insulation layer 102. The reinforcing layer 101 provides structural support and strength assurance, the sound insulation layer 102 uses sound insulation materials to reduce sound transmission, and the purification layer 103 purifies indoor air through adsorption materials. The layers are closely integrated and work together to achieve their functions.

[0032] Furthermore, in this embodiment, a support plate 15 is fixedly connected inside the reinforcing layer 101. The support plate 15 has a wave-shaped structure design, and a slot is formed between the support plates 15. A reinforcing rib 16 is fixedly connected inside the reinforcing layer 101 and inside the slot. The wave-shaped support plate 15 and the reinforcing rib 16 are designed to improve the structural strength and stability of the reinforcing layer 101. The wave-shaped structure design increases the support area and strength, while the reinforcing rib 16 further enhances the support effect.

[0033] Furthermore, in this embodiment, the sound insulation layer 102 is provided with sound insulation cotton 17 inside. The surface of the sound insulation cotton 17 is coated with strong adhesive. The sound insulation cotton 17 is bonded to the sound insulation layer 102 by the strong adhesive. The sound insulation cotton 17 reduces sound transmission by utilizing the sound insulation performance of the material itself. The strong adhesive ensures a tight connection between the sound insulation cotton 17 and the sound insulation layer 102, preventing sound from leaking through gaps.

[0034] Furthermore, in this embodiment, a honeycomb panel 18 is fixedly connected inside the purification layer 103. The honeycomb panel 18 is filled with activated carbon 19. The honeycomb panel 18 provides a large surface area for the activated carbon 19 to attach. The activated carbon 19 uses its adsorption properties to purify indoor air. When air passes through the purification layer 103, harmful substances are adsorbed and removed by the activated carbon 19 and discharged to the outside through the ventilation hole 14.

[0035] In this embodiment, the specific implementation scenario is as follows: A tight connection between the plates 1 is achieved through the cooperation of the annular block 2 and the annular groove 5, and the cooperation of the insert block 3 and the slot 6, and the dovetail groove 4 and the dovetail block 7. The rubber particles on the inner wall of the annular groove 5 enhance the stability and sealing of the connection. During installation, the annular block 2 and insert block 3 of one plate 1 are aligned with the annular groove 5 and slot 6 of another plate 1 and inserted until the dovetail groove 4 and the dovetail block 7 are fully engaged, thus completing the connection. Then, the connecting block 10 is inserted into the connecting groove 12, and then a set of plates 1 is slid. At this time, the connecting block 10 moves axially along the connecting groove 12. Finally, the two ends of the connecting block 10 are blocked by the extended edge, completing the lateral splicing between the two sets of plates 1. By installing the plate 1 with its top facing down on the ceiling, when the plate 1 is exposed to high humidity, it will... The water droplets are generated, and the figure-eight structure design helps guide the accumulated water to flow to the center more quickly, then gather into droplets, and then fall off due to gravity. The design of the wave-shaped support plate 15 and the reinforcing rib 16 is used to improve the structural strength and stability of the reinforcing layer 101. The wave-shaped structure design increases the support area and strength, while the reinforcing rib 16 further enhances the support effect, improves the overall strength, and prevents breakage. The sound insulation cotton 17 uses the sound insulation properties of the material itself to reduce sound transmission, and the strong adhesive ensures a tight connection between the sound insulation cotton 17 and the sound insulation layer 102, preventing sound leakage through gaps. The honeycomb panel 18 provides a large surface area for the activated carbon 19 to attach. The activated carbon 19 uses its adsorption properties to purify the indoor air. When the air passes through the purification layer 103, harmful substances are adsorbed and removed by the activated carbon 19 and discharged to the outside through the ventilation hole 14.
