Technical Field
[0001] This utility model relates to the field of fireproof board technology, specifically to a magnesium oxysulfate fireproof board. Background Technology
[0002] Fireproof boards are fire-resistant building materials used for surface decoration. Magnesium oxysulfate boards are air-hardening magnesium cementitious materials formed by active magnesium oxide and magnesium sulfate solution. Compared with silicate cement boards, magnesium oxysulfate boards have the characteristics of being relatively lighter, having lower thermal conductivity, and having excellent fire resistance. As a fire-resistant and insulating material, it has a wide range of applications and can be used to make building wall panels, door core panels, ceiling panels, packaging boxes, etc.
[0003] However, in actual use, the protective effect of a single fireproof board is poor. In actual use, multiple boards are usually bonded together with glue. The glue is easy to evaporate when heated, releasing harmful volatile substances such as formaldehyde. And the anchoring connection with nails is easy to be not tight enough, causing different boards to move and separate. Moreover, the function of a single fireproof board is relatively simple and cannot meet diverse needs such as heat insulation and sound insulation. Utility Model Content
[0004] The purpose of this invention is to provide a magnesium oxysulfate fireproof board that solves the problems of easy movement and limited effectiveness of existing fireproof boards when combined and connected.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a magnesium oxysulfate fireproof board, comprising a central board, a magnesium oxysulfate board, and a fireproof and soundproof cotton board, wherein magnesium oxysulfate boards are provided on both sides of the central board, and multiple fireproof and soundproof cotton boards are filled between the two sides of the central board and the magnesium oxysulfate board, and a fixing plate is provided at the top and bottom of the central board. The center plate used for support has multiple connecting columns arranged in an array throughout, and multiple mounting plates are fitted onto the outer wall of the connecting columns; The magnesium oxysulfate plate used for sealing has connecting grooves on the top and bottom of the side away from the center plate, and fixing grooves are provided on the side of the magnesium oxysulfate plate closest to the center plate at the corresponding positions of the connecting columns. The fireproof and soundproof cotton board used for filling has through holes inside that correspond to the connecting columns, and both sides of the fireproof and soundproof cotton board are in contact with the connecting columns.
[0006] Preferably, the interior of the center plate is rotatably connected to the connecting column via threads, and the outer wall of the connecting column is provided with a circumferential thread.
[0007] Preferably, both ends of the connecting column are provided with anti-slip textures, and both ends of the connecting column are respectively engaged with the inside of the fixing groove.
[0008] Preferably, the inner center of the mounting plate is threaded to the outer wall of the connecting column, and multiple fixing cones are inclinedly arranged on both sides of the connecting column, with the end of the fixing cone near the connecting column inclined in the direction corresponding to the inner thread of the mounting plate.
[0009] Preferably, the fixing plate has a receiving groove on the side near the center plate, and the two sides of the receiving groove are correspondingly engaged and fixed with the connecting groove. The top and bottom of the center plate and the fireproof and soundproof cotton board are inserted and fitted into the inside of the receiving groove.
[0010] Preferably, a groove corresponding to the center plate is formed at the center of the receiving groove, and connecting plates are fixedly connected to both sides of the center plate. The two ends of the fixing plates at the top and bottom of the center plate are fixedly connected to the connecting plates.
[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. The fixing cone can be inserted and snapped into the fireproof and soundproof cotton board. Because the fixing cone is tilted to one side, it can further insert and move into the fireproof and soundproof cotton board when the mounting plate rotates in the opposite direction, thus creating significant resistance and effectively preventing the mounting plate from rotating in the opposite direction. This achieves compression and fixation of the fireproof and soundproof cotton board by the mounting plate. Simultaneously, the supporting effect of the connecting column effectively prevents the fireproof and soundproof cotton board from falling to the bottom. Furthermore, the connection between the connecting column and the fixing groove on the side wall of the magnesium oxysulfate board achieves the installation connection of the magnesium oxysulfate board. The fixing groove also fixes the connecting column, preventing it from rotating or moving. The blocking effect of multiple connecting columns further limits the deformation of the magnesium oxysulfate board when heated. Additionally, the receiving grooves inside the top and bottom fixing plates further restrict and fix the center plate and the magnesium oxysulfate board, effectively achieving the installation and fixation of the entire device. This allows for the combination and connection of multiple panels without the need for glue.
[0012] 2. The magnesium oxysulfate boards on both sides first isolate and block external fires to prevent combustion. Even if the magnesium oxysulfate boards are damaged in a large fire, the fireproof and soundproof cotton boards continue to provide fire protection. The central board further provides fire protection, and the other side of the central board is also equipped with fireproof and soundproof cotton boards to effectively achieve heat insulation and fire protection. In use, due to the effect of the fireproof and soundproof cotton boards, sound waves are effectively reflected and absorbed by multiple fireproof and soundproof cotton boards after reaching the magnesium oxysulfate boards on one side, thus reducing the sound. Even if the sound waves pass through the fireproof and soundproof cotton boards on one side, they still need to pass through the central board and then through the fireproof and soundproof cotton boards on the other side before reaching the magnesium oxysulfate boards on the other side, effectively absorbing noise and achieving a sound insulation effect.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0017] This utility model provides, for example Figure 1-5 The diagram shows a magnesium oxysulfate fireproof board, comprising a central plate 1, magnesium oxysulfate plates 2, and fireproof and sound-insulating cotton boards 3. Magnesium oxysulfate plates 2 are provided on both sides of the central plate 1, and multiple fireproof and sound-insulating cotton boards 3 are filled between the sides of the central plate 1 and the magnesium oxysulfate plates 2. Fixing plates 4 are provided at the top and bottom of the central plate 1. Multiple connecting columns 101 are arranged in an array through the interior of the central plate 1 for support, and multiple mounting pieces 102 are sleeved on the outer wall of the connecting columns 101. Connecting grooves 201 are provided at the top and bottom of the magnesium oxysulfate plates 2 on the side away from the central plate 1, and fixing grooves 202 are provided at the corresponding positions of the connecting columns 101 on the side of the magnesium oxysulfate plates 2 closest to the central plate 1. Through holes corresponding to the connecting columns 101 are provided inside the fireproof and sound-insulating cotton boards 3 for filling, and both sides of the fireproof and sound-insulating cotton boards 3 are in contact with the connecting columns 101.
[0018] like Figure 2 , Figure 3As shown, the center plate 1 is rotatably connected to the connecting column 101 via threads. The outer wall of the connecting column 101 has a circumferential thread, and both ends of the connecting column 101 are provided with anti-slip textures. Both ends of the connecting column 101 are respectively engaged with the interior of the fixing groove 202. The interior center of the mounting plate 102 is threadedly connected to the outer wall of the connecting column 101. Multiple fixing cones 103 are inclinedly provided on both sides of the connecting column 101, and the end of the fixing cone 103 near the connecting column 101 is threaded into the interior of the mounting plate 102. With the mounting plates 102 tilted in the corresponding direction, they are fixedly attached to the outer wall of the fireproof and soundproof cotton board 3, squeezing the fireproof and soundproof cotton board 3. This allows the fixing cone 103 to be inserted and engaged with the fireproof and soundproof cotton board 3. At the same time, because the fixing cone 103 is tilted to one side, it can be further inserted and moved into the fireproof and soundproof cotton board 3 when the mounting plate 102 rotates in the opposite direction, thus forming greater resistance and effectively preventing the mounting plate 102 from rotating in the opposite direction, thereby achieving the squeezing and fixing of the fireproof and soundproof cotton board 3 by the mounting plate 102.
[0019] like Figure 1 , Figure 4 As shown, the fixing plate 4 has a receiving groove 401 on one side near the center plate 1. The two sides of the receiving groove 401 are correspondingly engaged and fixed with the connecting groove 201. The top and bottom of the center plate 1 and the fireproof and soundproof cotton board 3 are inserted into and fitted with the inside of the receiving groove 401. The center of the receiving groove 401 has a groove corresponding to the center plate 1. The two sides of the center plate 1 are fixedly connected with connecting plates 402. The two ends of the fixing plates 4 at the top and bottom of the center plate 1 are fixedly connected to the connecting plates 402. The receiving groove 401 inside the top and bottom fixing plates 4 further restricts and fixes the center plate 1 and the magnesium oxysulfate board 2, realizing the installation and fixation of the entire device. It effectively realizes the combination and fixation of multiple plates and avoids separation and displacement.
[0020] In use, multiple fireproof and soundproof cotton boards 3 can be conveniently installed on both sides of the center plate 1, allowing the fireproof and soundproof cotton boards 3 to be fixedly connected to the connecting column 101 through each other. Simultaneously, the mounting plates 102 are fixedly attached to the outer wall of the fireproof and soundproof cotton boards 3, squeezing them. This allows the fixing cone 103 to insert and engage with the fireproof and soundproof cotton board 3. Because the fixing cone 103 is tilted to one side, it can further insert and move into the fireproof and soundproof cotton board 3 when the mounting plate 102 rotates in the opposite direction, creating significant resistance and effectively preventing the mounting plate 102 from rotating in the opposite direction. This achieves the squeezing and fixing of the fireproof and soundproof cotton board 3 by the mounting plate 102. Furthermore, due to the connecting column 101... The supporting function of 1 can also effectively prevent the fireproof and soundproof cotton board 3 from moving to the bottom and avoid displacement. At the same time, the connection of the connecting column 101 and the fixing groove 202 on the side wall of the magnesium oxysulfate board 2 can realize the installation connection of the magnesium oxysulfate board 2. The fixing groove 202 can also fix the connecting column 101 to prevent it from rotating and moving. Furthermore, the blocking effect of multiple connecting columns 101 can further limit the deformation of the magnesium oxysulfate board 2 when heated. At the same time, the receiving groove 401 inside the top and bottom fixing plates 4 can further restrict and fix the center plate 1 and the magnesium oxysulfate board 2, realizing the installation and fixation of the entire device. This effectively realizes the combination and fixation of multiple plates, avoiding separation and displacement, and eliminating the need for glue.
[0021] In use, the magnesium oxysulfate boards 2 on both sides can easily isolate and block external fires, preventing combustion. Even if the magnesium oxysulfate boards 2 are damaged in a large fire, the fireproof and sound-insulating cotton boards 3 continue to provide fire protection. The central board 1 further enhances fire protection, and the other side of the central board 1 is also equipped with fireproof and sound-insulating cotton boards 3 to effectively achieve heat insulation and fireproofing. Furthermore, due to the function of the fireproof and sound-insulating cotton boards 3, sound waves can be effectively transmitted to the magnesium oxysulfate boards 2 on one side and then... Multiple fireproof and soundproof cotton boards 3 reflect and absorb sound, reducing its intensity. Even if sound waves pass through the fireproof and soundproof cotton board 3 on one side of the central board 1, they still need to pass through the central board 1 and then through the fireproof and soundproof cotton board 3 before reaching the magnesium oxysulfate board 2 on the other side. This effectively absorbs noise again, achieving a sound insulation effect. The connecting plates 402 on both sides allow for easy grooving or installation of shafts, facilitating processing and use while preventing damage to the magnesium oxysulfate board 2 and the internal fireproof and soundproof cotton board 3. This gives the device multiple functions, effectively meeting the needs of users.
[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
