[0041] Specifically, the accommodation cavity of the first keel 21 provides installation space for the top of the wallboard 13, the base strip 22 serves as a rigid support member and can uniformly transmit the pushing force of the adjusting screw 23 to the first sealing strip 15 to realize sealing and pressing, the threaded connection structure of the adjusting screw 23 allows the user to switch the sealing and unlocking states by simply screwing, when loosening, the base strip 22 drives the first sealing strip 15 to rise, and at the same time, the pressure of the first sealing strip 15 is released, so that the first sealing strip 15 is not damaged by friction with the wallboard 13 during disassembly and assembly, and the wallboard 13 can be separated without disassembling the sealing member, thereby ensuring the reusability of the sealing structure, the first sealant 203 is filled in the gap between the first keel 21 and the floor slab 11, and forms double sealing with the first sealing strip 15, thereby further improving the reliability of smoke prevention.

[0042] As Figure 6 , Figure 7 and Figure 11As shown, the second quick-release assembly further comprises a second keel 34 and a clamping strip 35, the connecting strip 31 and the second keel 34 are fixed on both sides of the bottom of the wallboard 13, and the top of the connecting strip 31 and the second keel 34 are fixed to the wallboard 13 through a plurality of bolts; the second keel 34 and the clamping strip 35 are embedded in the ceiling plate 12 and fixed to the ceiling plate 12, and the second keel 34 and the clamping strip 35 are located on both sides of the smoke blocking vertical wall 14, and the second sealant 301 is filled between the opposite surfaces of the smoke blocking vertical wall 14, the second keel 34 and the clamping strip 35 to achieve sealing of the top of the smoke blocking vertical wall 14; a top rod 36 is arranged between the connecting strip 31 and the second keel 34, and the hook 33 is connected to the top rod 36 through a spring latch 37; the top rod 36 slides in the vertical direction, and pushing the top rod 36 can drive the hook 33 to open and close around the rotating shaft through the spring latch 37; the clamping groove 32 and the connecting strip 31 are a concave-convex fitting structure, a groove 302 is formed on one side of the clamping groove 32 facing the connecting strip 31, and a protrusion 303 is correspondingly formed on the connecting strip 31, the protrusion 303 is embedded in the groove 302 to achieve pre-positioning, and the hook 33 can be clamped into a locking hole 304 formed in the clamping groove 32 to form locking.

[0043] Specifically, the second keel 34 and the clamping strip 35 provide lateral positioning and installation reference for the smoke blocking vertical wall 14, and the gap is filled with the second sealant 301 to achieve lateral sealing of the top of the smoke blocking vertical wall 14, the concave-convex fitting structure of the connecting strip 31 and the clamping groove 32 can quickly achieve pre-positioning during installation, avoid alignment deviation of the hook 33, and improve installation efficiency; the linkage structure of the top rod 36 and the spring latch 37 converts the driving force in the vertical direction into the opening and closing action of the hook 33, so that the disassembly and assembly of the smoke blocking vertical wall 14 do not need to directly contact the hook 33, the operation is more convenient, and it is suitable for narrow space operation below the ceiling.

[0044] One end of the spring latch 37 is connected to the hook 33, and the other end penetrates through the connecting strip 31 and abuts against the top rod 36, and a reset spring is sleeved outside the spring latch 37; the top rod 36 is connected with an adjusting bolt 38 at the bottom, the top end of the adjusting bolt 38 is fixed to the top rod 36, and the rod part penetrates through the second keel 34 and is threadedly connected with the second keel 34; clockwise rotation of the adjusting bolt 38 drives the top rod 36 to move upward, and the spring latch 37 is automatically opened and unlocked by being pressed by the inclined surface to drive the hook 33; counterclockwise rotation of the adjusting bolt 38 makes the top rod 36 move downward, and the reset spring drives the spring latch 37 to reset and drive the hook 33 to close and lock.

The wave-shaped contact surfaces of the first sealing strip 15 and the second sealing strip 16 can fill the assembly gap through their own deformation, so that even if there is a slight installation deviation of the wall panel 13 or the smoke barrier 14, a seal can still be formed. Meanwhile, the wave-shaped structure increases the sealing contact area, reduces the risk of smoke penetration, and improves the overall smoke prevention effect.

[0049] Specifically, the stepped structure of the second keel 34 has dual functions of positioning and installation, the top step surface of which is fixed with the wall panel 13 to limit the horizontal displacement of the wall panel 13, avoiding the generation of gaps at the joint; meanwhile, the step surface provides a stable installation reference for the second sealing strip 16, so that the second sealing strip 16 can fit the gap between the bottom of the wall panel 13 and the second keel 34, forming an integrated structure of positioning constraint and sealing protection, which not only ensures the structural stability, but also simplifies the installation process.

[0050] Figure 12 , Figure 13 , Figure 14and Figure 15 As shown, the two ends of each wallboard 13 are integrally formed with semi-open circular interfaces, the opening directions of the semi-open circular interfaces at the two ends of the same wallboard 13 are opposite, the semi-open circular interfaces of adjacent wallboards 13 are buckled with each other through the two ends, and a complete circular cavity is formed after abutting.

[0052] Specific use and effects of the embodiment:

[0053] First, the wallboard 13 is installed, the first keel 21 is fixed to the bottom of the floor slab 11 through multiple expansion bolts, the bolts are uniformly arranged along the length direction of the first keel 21 to ensure fixation, then the base strip 22 and the first sealing strip 15 are placed into the receiving cavity of the first keel 21 from top to bottom, multiple wallboards 13 are inserted into the receiving cavity, the wallboards 13 are vertically pushed upward to align and engage the cooperating hooks 202 with the clamping hooks 201 of the first keel 21, the preliminary fixation of the wallboards 13 is completed, then the adjusting screw 23 on the first keel 21 is tightened, the base strip 22 is pushed to extrude the first sealing strip 15, and the first sealing strip 15 is attached to the top of the wallboard 13, finally the first sealant 203 is filled in the gap between the first keel 21 and the floor slab 11, the installation and top sealing of the wallboard 13 are completed, then the smoke stopping vertical wall 14 is installed, the connecting strip 31 and the second keel 34 are fixed to the bottom of the wallboard 13 through bolts, the second keel 34 and the clamping strip 35 are embedded and fixed in the reserved position of the suspended ceiling 12, the clamping groove 32 at the top of the smoke stopping vertical wall 14 is aligned with the protrusion 303 of the connecting strip 31, and is embedded into the recess 302 to realize pre-positioning, the adjusting screw 38 is counterclockwise rotated to drive the top rod 36 to move downward, the reset spring drives the spring latch 37 to reset, and the hook 33 is clamped into the lock hole 304 of the clamping groove 32 to form locking. Finally, the second sealant 301 is filled in the gap between the smoke stopping vertical wall 14 and the second keel 34 and the clamping strip 35, the second sealing strip 16 is attached to the top step surface of the second keel 34 and attached to the bottom of the wallboard 13, and the installation of the complete set of devices is completed.

[0054] In daily use, after installation, the wallboard 13 forms a smoke-proof blocking barrier in the ceiling, the smoke-blocking vertical wall 14 divides the smoke-proof partition below the ceiling plate 12, and the two cooperate to form a double smoke-proof structure. The first sealing strip 15, the second sealing strip 16, the first sealing glue 203, and the second sealing glue 301 jointly act to block all connecting gaps and prevent the spread of smoke in the ceiling, ensuring the smoke-proof partition isolation effect of public buildings such as shopping malls and office complexes, gaining time for personnel evacuation. The circular cavity of the wallboard 13 enhances the structural stability of the wallboard 13 joint, and the stepped second keel 34 limits the horizontal displacement of the wallboard 13 to prevent sealing failure due to vibration during long-term use, ensuring long-term and reliable smoke-blocking function.

[0055] When it is necessary to overhaul the mechanical and electrical pipelines in the ceiling, the ceiling plate 12 or the wallboard 13 does not need to be damaged. Only the adjusting screw 23 on the first keel 21 needs to be loosened to release the compression force of the first sealing strip 15. The wallboard 13 can be pulled vertically downward to separate the cooperating hook 202 from the clamping hook 201, quickly remove the wallboard 13, and expose the pipeline for maintenance. If the smoke-blocking vertical wall 14 needs to be overhauled, the adjusting bolt 38 is turned clockwise to drive the top rod 36 to move upward, and the hook 33 is unlocked by being expanded through the inclined surface extrusion spring latch 37 to separate the smoke-blocking vertical wall 14 from the connecting strip 31. The disassembly process does not damage the component structure.

[0056] After the overhaul is completed, the wallboard 13 can be inserted into the receiving cavity of the first keel 21 again, the clamping hook 201 and the cooperating hook 202 are re-engaged, the adjusting screw 23 is tightened to restore the seal, the smoke-blocking vertical wall 14 is quickly connected through the predetermined positioning structure of the clamping groove 32 and the connecting strip 31, and the adjusting bolt 38 is reversely rotated to be re-locked. All components can be reused without the need for additional replacement materials, reducing construction waste and procurement costs. Daily maintenance only needs to check the integrity of the first sealing strip 15, the second sealing strip 16, and the first sealing glue 203 and the second sealing glue 301. If aging occurs, they can be directly replaced, which is convenient to operate and ensures that the device maintains good smoke-blocking sealing performance for a long time.
