[0002] Air duct is a common exhaust ventilation accessory in building structures. In order to improve the fire resistance of air duct, air duct is usually spliced ​​and formed by fireproof board. Magnesium floating bead high crystal air duct is a new generation of environmentally friendly and energy-saving air duct after inorganic glass air duct and glass magnesium air duct. The product structure is a homogeneous material. Magnesium floating bead high crystal air duct can be used for various HVAC ventilation ducts, smoke exhaust ducts, etc.

[0003] A magnesium floating bead high crystal air duct fireproof board is disclosed in a Chinese utility model patent with publication number CN219120742U, including a fireproof substrate one on both sides of the tube body and a fireproof substrate two at the upper and lower parts, and mortise and tenon connection mechanisms are arranged on both sides of the fireproof substrate one and the fireproof substrate two to facilitate the mutual connection of the plates and solve the instability problem caused by the smooth surface when splicing the traditional air duct plates, and two groups of fireproof substrates one and two groups of fireproof substrates two are spliced ​​into an air duct body through the mortise and tenon connection mechanism and connected with multiple groups of bolts, and the fireproof substrate one and the fireproof substrate two include a magnesium steel substrate layer and a protective layer group arranged on the top of the magnesium steel substrate layer, and the inner surface of the magnesium steel substrate layer is provided with an inner protective layer, thereby increasing the service life of the air duct formed by the fireproof board.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device connects fireproof substrate one and fireproof substrate two by interconnecting the conical clip-on strip and the conical clip-on groove. In actual operation, the conical clip-on strip is often unable to move smoothly into the conical clip-on groove due to tolerance problems. The staff needs to continuously knock on the fireproof substrate two to move the conical clip-on strip, which is inconvenient to operate and easily causes damage to the fireproof substrate two.

[0014] Furthermore, a fixing hole matching with the second sliding rod is provided on the inner top wall of the fixing groove.

[0015] By adopting the above technical solution, when the second slide bar moves upward under the action of the first slide bar, the upper end of the second slide bar is connected to the fixing hole, thereby reducing the probability of the support plate and the fixing groove being separated from each other.

[0016] Furthermore, the thickness of the first fireproof substrate and the second fireproof substrate are both 9 mm.

In this process, since the width of the fixing groove is greater than the height of the support plate, the difficulty of the staff to connect the support plate and the fixing groove is reduced, thereby improving the staff's user experience;

[0022] 2. In the present application, when the staff needs to fix the support plate, the staff only needs to turn the bolt to move the bolt downward, so that the bolt is pressed against the first inclined surface, so that the first slide bar moves toward the direction close to the second slide bar under the action of the bolt, so that the first slide bar is pressed against the second inclined surface, so that the second slide bar moves upward and presses against the inner top wall of the fixing groove, so that the support plate remains stable;

[0030] In the existing technology, the fireproof clean board of magnesium rock beads is made of color coated steel plate as the surface material and fireproof magnesium rock beads as the core material. The process of plate forming, gluing, core material filling, composite pressing and finished product stacking is realized through precise measurement and intelligent control, so that the accuracy, strength, flatness and aesthetics of the clean board are greatly improved, and the product quality is more stable.

[0031] like Figure 1-4 As shown, the embodiment of the present application discloses a rock magnesium floating bead fireproof board, including a first fireproof substrate 1, a second fireproof substrate 11, a support plate 2, a fixing assembly 4, a tension spring 5, a moving rod 6, an elastic band and a silicone sheet 7. The thickness of the first fireproof substrate 1 and the second fireproof substrate 11 are both 9 mm, the support plate 2 is a rectangular plate structure, the support plate 2 is fixed on the side wall of the first fireproof substrate 1, and a fixing groove 21 is opened on the side wall of the second fireproof substrate 11 close to the first fireproof substrate 1, and the width of the fixing groove 21 is greater than the height of the support plate 2.

[0032] The upper surface of the support plate 2 is provided with a plurality of L-shaped grooves 3 distributed at equal intervals, and the upper surface of the support plate 2 is provided with a movable groove 31 interconnected with the L-shaped groove 3. The fixing assembly 4 is arranged on the support plate 2 for docking the first fireproof substrate 1 and the second fireproof substrate 11, and the fixing assembly 4 comprises a first slide bar 41, a second slide bar 42 and a bolt 43. The first slide bar 41 is a rectangular rod-shaped structure, and the first slide bar 41 is slidably arranged in the horizontal part of the L-shaped groove 3, and a placement groove 44 is arranged on the upper surface of the first slide bar 41, and a first inclined surface 45 is arranged on the inner wall of the placement groove 44 close to the second slide bar 42.

[0033] When the staff needs to fix the support plate 2, the staff only needs to turn the bolt to move the bolt downward, thereby making the bolt press against the first inclined surface 45, so that the first slide bar 41 moves toward the second slide bar 42 under the action of the bolt, and then makes the first slide bar 41 press against the second inclined surface 46, so that the second slide bar 42 moves upward and presses against the inner top wall of the fixing groove 21, thereby keeping the support plate 2 stable.

[0034] One end of the tension spring 5 is fixed to the side wall of the first slide bar 41 away from the second slide bar 42, and the other end of the tension spring 5 is fixed to the inner wall of the horizontal portion of the L-shaped groove 3. When the bolt and the first slide bar 41 are separated from each other, the first slide bar 41 automatically returns to its original position under the action of the tension spring 5, and the staff does not need to manually slide the first slide bar 41, thereby improving the staff's use experience.

[0035] The moving rod 6 is a rectangular rod-shaped structure. The moving rod 6 is slidably disposed in the moving groove 31 , and the bottom surface of the bolt is pressed against the upper surface of the moving rod 6 .

[0039] In order to improve the aesthetics of the first fireproof substrate 1 , decorative base paper 8 is provided on the side walls of the first fireproof substrate 1 and the second fireproof substrate 11 .

[0040] In this embodiment, the first fireproof substrate 1 and the second fireproof substrate 11 use fireproof floating beads as core materials and use color coated steel plates as surface materials.

[0041] The use principle of a magnesium floating bead fireproof board in this embodiment is:

[0042] When the staff needs to connect the first fireproof substrate 1 with the second fireproof substrate 11, the staff needs to connect the support plate 2 with the fixing groove 21 to initially stabilize the support plate 2. Subsequently, the staff needs to turn the bolt to start the fixing assembly 4, and then the fixing assembly 4 fixes the support plate 2, so that the support plate 2 remains stable. In this process, since the width of the fixing groove 21 is greater than the height of the support plate 2, the difficulty of the staff to connect the support plate 2 with the fixing groove 21 is reduced, thereby improving the staff's use experience.
