[0035] Example

[0036] See also Figure 1 This embodiment provides a natural smoke exhaust structure suitable for pressurized buildings, including a first smoke exhaust structure and a second smoke exhaust structure. The first smoke exhaust structure and the second smoke exhaust structure are both arranged on the top of the side wall of the pressurized building. Preferably, in this embodiment, see Figure 3 The first smoke exhaust structure and the second smoke exhaust structure are both arranged at the top of the side wall of the pressurized building corresponding to the smoke storage bin A (the smoke storage bin A is the part where smoke gathers in the air above the room when a fire occurs in the pressurized building) to discharge the smoke in the pressurized building;

[0037] See also Figure 1 The first smoke exhaust structure includes a smoke exhaust window 1, which includes a plurality of smoke exhaust window monomers arranged in parallel, and the smoke exhaust window monomers are arranged on the side wall; in this embodiment, see Figure 1 , Figure 3-Figure 5 A fixed window 6 is provided on the side wall, and the fixed window 6 is fixed on the side wall panel 3. The smoke exhaust window 1 is provided above the fixed window 6. In this embodiment, a window sill 7 is further provided at the corresponding position of the fixed window 6 to reinforce the fixed window 6.

[0038] Preferably, see Figure 2-Figure 5The smoke exhaust window unit includes a window frame 1.1 and a window sash 1.2. The window frame 1.1 is fixed to the side wall panel 3, and the window sash 1.2 is hinged to the window frame 1.1. In this embodiment, the smoke exhaust window unit is an inward-opening structure and has an upper-opening structure. The lower part of the window sash 1.2 is hinged to the window frame 1.1 through a smoke exhaust window hinge 1.5. The opening form of the smoke exhaust window unit is not limited, and can be inward-opening or outward-opening. The window sash 1.2 can be set on the window frame in a top-hung or casement manner.

[0039] See also Figure 2 、 Figure 4 and Figure 5 A driving device 1.3 is provided between the window sash 1.2 and the window frame 1.1, and the driving device 1.3 drives the window sash 1.2 to open or close relative to the window frame 1.1. Preferably, the driving device 1.3 adopts a hydraulic rod or an electric push rod (the present application adopts a hydraulic rod); the fixed end of the driving device 1.3 is provided on the window frame 1.1, and the movable end of the driving device 1.3 is provided on the window sash 1.2. Preferably, two hydraulic rods are provided, which are respectively located on the frame bars on the left and right sides of the window frame 1.1. In addition, the provision of a hydraulic rod can control the opening angle of the window sash 1.2 (in this embodiment, the opening angle must meet ≥75°), meet the demand for smoke exhaust volume, and prevent the window sash 1.2 from falling, thereby reducing safety hazards.

[0040] More preferably, the window frame 1.1 is provided with a locking device 1.4, which is used to achieve locking between the window frame 1.1 and the window sash 1.2. Figure 2 and Figure 5 The locking device 1.4 is arranged on the upper part of the window frame 1.1. The locking device 1.4 is preferably an electromagnetic suction cup, and there are two or more electromagnetic suction cups. By powering on and off the electromagnetic suction cups, locking and unlocking between the window frame 1.1 and the window sash 1.2 are achieved.

[0041] In this embodiment, a sealing strip 1.6 is further provided on the window frame 1.1 for sealing between the window frame 1.1 and the window sash 1.2 to meet the sealing requirements of the pressurized building.

[0042] In this embodiment, see Figure 1 The second smoke exhaust structure includes a plurality of smoke exhaust valve assemblies 2 arranged in parallel. The smoke exhaust valve assemblies 2 are arranged on the side wall and located above the smoke exhaust window 1.

[0043] See also Figure 3 The smoke exhaust valve assembly 2 includes a smoke exhaust valve 2.1 and a smoke exhaust pipe 2.2. The outlet of the smoke exhaust valve 2.1 is connected to the smoke exhaust pipe 2.2. The inlet of the smoke exhaust valve 2.1 is set in the pressurized building. The smoke exhaust pipe 2.2 is set through the side wall. Preferably, the smoke exhaust valve 2.1 is an electric smoke exhaust valve.

[0044] In this embodiment, a louver air outlet 4 is provided at a position corresponding to the outlet end of the smoke exhaust pipe 2.2 on the outdoor side of the side wall. The louver air outlet 4 can prevent dust, debris, etc. from entering the smoke exhaust pipe 2.2 under normal conditions and affecting the smoke exhaust function of the smoke exhaust valve assembly 2.

[0045] In this embodiment, a smoke sensing device 5 is provided on the floor above the cigarette storage bin A.

[0046] This embodiment also includes a control system, which is connected to the smoke sensor 5, the smoke exhaust valve 2.1, the electromagnetic suction cup and the driving device 1.3, and is used to drive the corresponding components to operate.

[0047] When a fire occurs, the pressure difference between the indoor and outdoor areas of the pressurized building is large. The smoke sensor 5 detects the smoke signal and transmits it to the control system. The control system controls the operation of the smoke exhaust valve 2.1. The smoke exhaust valve 2.1 opens and uses the pressure difference between the indoor and outdoor areas of the pressurized building to discharge the smoke directly to the outside through the louver vents 4, thereby achieving pressure relief in the room.

[0048] The pressure in the pressurized building gradually decreases. When the indoor and outdoor pressures are close to each other, the control system controls the electromagnetic suction cup to cut off the power, and the lock between the window sash 1.2 and the window frame 1.1 is released. The control system controls the hydraulic rod to operate, and the smoke exhaust window 1 automatically opens under the dual action of the hydraulic rod and its own gravity. The smoke is discharged through the smoke exhaust window 1 and the smoke exhaust valve assembly 2.

[0049] The natural smoke exhaust structure provided in this embodiment is suitable for pressurized buildings. At the early stage of a fire, the smoke exhaust valve assembly 2 realizes natural smoke exhaust and pressure relief in the pressurized building. When the pressure inside and outside the pressurized building is equal, the natural smoke exhaust in the pressurized building is realized through the cooperation of the smoke exhaust window 1 and the smoke exhaust valve assembly 2. This reduces the risk in the prior art that when the natural smoke exhaust window is opened under pressure, people or objects in the room may be knocked down by the air pressure, and glass may be broken under the impact of the air pressure, thereby preventing the occurrence of secondary disasters and reducing the safety risks caused by secondary disasters.

[0050] This embodiment also provides a pressurized building, including the smoke exhaust structure as described above, which is arranged on the side wall of the pressurized building. Through the smoke exhaust structure, natural smoke exhaust of the pressurized building is achieved, while reducing the safety risks caused by secondary disasters.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
