Description

Technical Field

[0001] This application relates to the technical field of fire protection, and in particular to a fire protection structure and building for use in buildings. Background Technology

[0002] An anteroom is typically a shared vestibule for multiple households within a building. The building's ventilation system can deliver outdoor air into the anteroom, giving it a certain amount of residual pressure. In the event of a fire, the residual pressure generated by the ventilation system can prevent smoke from entering the anteroom, thus preventing people in the anteroom from inhaling smoke and ensuring the safe evacuation of people.

[0003] In traditional technology, in order to ensure that the building’s anteroom has residual pressure, an air supply system is usually installed in the anteroom. However, the installation of the air supply system will occupy part of the anteroom space, thus restricting the residents’ activity space. Utility Model Content

[0004] Therefore, it is necessary to address the problem that placing the air supply system in the anteroom in traditional technologies would occupy part of the anteroom space and restrict the residents' activity space, and to provide a fire protection structure and building for buildings.

[0005] The technical solution is as follows:

[0006] One embodiment provides a fire protection structure for a building, comprising:

[0007] The exterior wall encloses a public area;

[0008] A first partition wall, which is connected to the outer wall and located within the public area, divides the public area into a stairwell and an anteroom;

[0009] A second partition wall, located within the stairwell area, connects to the outer wall and the first partition wall at opposite ends, respectively, dividing the stairwell area into a stairwell and a pressurized room. The first partition wall has a first opening connecting the pressurized room and the anteroom. The outer wall has a first air inlet communicating with the pressurized room.

[0010] A pressurization module, which is connected to the first air inlet.

[0011] The aforementioned fire protection structure for buildings divides the public area enclosed by the outer wall into a stairwell and an anteroom using a first partition wall. The second partition wall further divides the stairwell into a stairwell and a pressurization chamber. The pressurization module can deliver airflow to the pressurization chamber through the first air inlet. The airflow in the pressurization chamber then enters the anteroom through the first opening, ensuring that the anteroom has residual pressure and preventing smoke generated during a fire from entering the anteroom. Compared with traditional technologies, the aforementioned fire protection structure for buildings not only prevents residents in the anteroom from inhaling smoke during a fire, but also does not occupy the anteroom space, thus ensuring that residents have sufficient activity space.

[0012] In one embodiment, the fire protection structure for the building further includes a third partition wall located within the pressurization chamber. The opposite ends of the third partition wall are connected to the outer wall and the second partition wall, respectively, to divide the pressurization chamber into a first pressurization chamber and a second pressurization chamber. The pressurization module is located outside the public area and communicates with the first pressurization chamber through the first air inlet. The first pressurization chamber communicates with the anteroom through the first opening. The outer wall has a second air inlet communicating with the second pressurization chamber. The pressurization module communicates with the second air inlet. The second partition wall has a second opening, and the second pressurization chamber communicates with the stairwell through the second opening.

[0013] In one embodiment, the fire protection structure for the building further includes a first air volume regulator and a second air volume regulator. The first air volume regulator is disposed at the first opening and is used to control the air flow through the first opening, and the second air volume regulator is disposed at the second opening and is used to control the air flow through the second opening.

[0014] In one embodiment, the first airflow regulating component includes a first frame and first louvers. The first frame is disposed at the first opening. At least two first louvers are provided, all of which are parallel and spaced apart within the first frame. A first air inlet gap is formed between adjacent first louvers. All first louvers are rotatable, allowing the sides of adjacent first louvers that are closest to each other to move closer or further apart, thereby narrowing or widening the first air inlet gap between adjacent first louvers; or / and,

[0015] The second air volume regulating component includes a second frame and a second 100-blade. The second frame is located at the second opening. There are at least two 100-blades. All the 100-blades are arranged parallel to each other and spaced apart in the second frame. A second air inlet gap is formed between two adjacent 100-blades. All the 100-blades can rotate so that the side of two adjacent 100-blades that is close to each other can move closer or further away from each other, thereby narrowing or widening the second air inlet gap between two adjacent 100-blades.

[0016] In one embodiment, the building has at least two floors, and at least two of the first partition wall and the second partition wall are provided and are provided one-to-one with the floors. The first pressurization chamber is provided through all the floors, and all the first openings are connected to the first pressurization chamber. The second pressurization chamber is provided through all the floors, and all the second openings are connected to the second pressurization chamber.

[0017] In one embodiment, the pressurization module includes a pressurization room located on any of the floors. The pressurization room is connected to the first pressurization chamber through the first air inlet, and the pressurization room is also connected to the second pressurization chamber through the second air inlet.

[0018] In one embodiment, the pressurization module further includes a first pressurization duct and a second pressurization duct, both of which are located in the pressurization room. The first pressurization duct is connected to the first air inlet, and the second pressurization duct is connected to the second air inlet.

[0019] In one embodiment, the pressurization module further includes a first pressurization fan and a second pressurization fan, wherein the first pressurization fan is connected to the first pressurization duct and the second pressurization fan is connected to the second pressurization duct.

[0020] In one embodiment, the pressurization module further includes a first fire damper and a second fire damper, wherein the first fire damper is disposed in the first pressurization duct and the second fire damper is disposed in the second pressurization duct.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0035] Please see Figures 1 to 2 One embodiment of this application provides a fire protection structure for a building, including an exterior wall 100, a first partition wall 210, a second partition wall 220, and a pressurization module 300. The exterior wall 100 encloses a public area 400. The first partition wall 210 is connected to the exterior wall 100 and located within the public area 400, dividing the public area 400 into a stairwell 410 and an anteroom 420. The second partition wall 220 is located within the stairwell 410, and its opposite ends are connected to the exterior wall 100 and the first partition wall 210, respectively, dividing the stairwell 410 into a stairwell 411 and a pressurization chamber 412. The first partition wall 210 has a first opening 211 that connects the pressurization chamber 412 and the anteroom 420. The exterior wall 100 has a first air inlet 110 that communicates with the pressurization chamber 412. The pressurization module 300 communicates with the first air inlet 110.

[0036] In the aforementioned fire protection structure for buildings, the first partition wall 210 divides the public area 400 enclosed by the outer wall 100 into a stairwell 410 and an anteroom 420. The second partition wall 220 divides the stairwell 410 into a stairwell 411 and a pressurization room 412. The pressurization module 300 can deliver airflow to the pressurization room 412 through the first air inlet 110. The airflow in the pressurization room 412 then enters the anteroom 420 through the first opening 211 to ensure that the anteroom 420 has residual pressure and to prevent smoke generated by a fire from entering the anteroom 420. Compared with traditional technologies, the aforementioned fire protection structure for buildings can not only prevent residents in the anteroom 420 from inhaling smoke during a fire, but also does not occupy the space of the anteroom 420, thereby ensuring that residents have sufficient activity space.

[0037] As a further explanation, the fire protection structure for buildings in the above embodiments can be applied to single-story buildings (i.e., single-story buildings) or buildings with multiple floors. The fire protection structure is set on at least one floor of the multi-story building to prevent smoke from entering the floor, while not occupying the activity space of the users on that floor in the anteroom 420.

[0038] Specifically, the anteroom 420 is a shared anteroom 420, which can also serve as a shared lobby or corridor space for multiple users. The fire protection structure in this application can prevent smoke from entering the anteroom 420 and causing the residents in the anteroom 420 to inhale smoke in the event of a fire, and can also ensure the activity space in the shared anteroom 420 under normal circumstances.

[0039] Furthermore, the stairwell area 410 is a stairwell passage for residents to enter, exit, or evacuate daily, and has a lot of unused space. By setting the second partition wall 220 inside the stairwell area 410, a part of the stairwell area 410 can be used as a pressurization room 412. The first air inlet 110 of the pressurization room 412 is connected to the pressurization module 300. In this way, while achieving the pressurization effect on the anteroom 420, the unused space of the stairwell area 410 can also be fully utilized, thereby improving the space utilization rate.

[0040] Optionally, the pressurization module 300 can be a pressurization fan, air booster, etc., without specific limitations.

[0041] Specifically, please refer to Figure 1 and Figure 2 The second partition wall 220 is a 20mm precast straight concrete slab.

[0042] Please see Figure 1 and Figure 2 In one embodiment, the fire protection structure for the building further includes a third partition wall 230 located within the pressurization chamber 412. The opposite ends of the third partition wall 230 are connected to the outer wall 100 and the second partition wall 220, respectively, to divide the pressurization chamber 412 into a first pressurization chamber 4121 and a second pressurization chamber 4122. The pressurization module 300 is located outside the public area 400 and communicates with the first pressurization chamber 4121 through a first air inlet 110. The first pressurization chamber 4121 communicates with the anteroom 420 through a first opening 211. The outer wall 100 has a second air inlet 120 communicating with the second pressurization chamber 4122. The pressurization module 300 communicates with the second air inlet 120. The second partition wall 220 has a second opening 221, and the second pressurization chamber 4122 communicates with the stairwell 411 through the second opening 221.

[0043] The third partition wall 230 divides the pressurization chamber 412 into a first pressurization chamber 4121 and a second pressurization chamber 4122. The first pressurization chamber 4121 is connected to the anteroom 420 through a first opening 211. Thus, the pressurization module 300 introduces airflow into the first pressurization chamber 4121 through the first air inlet 110, and the airflow in the first pressurization chamber 4121 then enters the anteroom 420 through the first opening 211 to pressurize the anteroom 420. The second pressurization chamber 4122 is connected to the second opening 22 on the second partition wall 220. 1. The pressurization module 300 is connected to the stairwell 411. In this way, the pressurization module 300 introduces airflow into the second pressurization chamber 4122 through the second air inlet 120. The airflow in the second pressurization chamber 4122 then enters the stairwell 411 through the second opening 221 to pressurize the stairwell 411. In this way, it can simultaneously ensure that the anteroom 420 and the stairwell 411 have residual pressure, preventing smoke generated by the fire from entering the anteroom 420 and the stairwell 411, and ensuring that residents can escape smoothly through the anteroom 420 and the stairwell 411 in the event of a fire.

[0044] Furthermore, the pressurization module 300 in this application not only ensures that the anteroom 420 and stairwell 411 have residual pressure in the event of a fire, but can also be used for daily ventilation of the anteroom 420 and stairwell 411. By setting a third partition wall 230 to divide the pressurization chamber 412 into a first pressurization chamber 4121 and a second pressurization chamber 4122, the first pressurization chamber 4121 and the second pressurization chamber 4122 are respectively responsible for providing airflow to the anteroom 420 and the stairwell 411. In this way, it is possible to control the first pressurization chamber 4121 to provide airflow to the anteroom 420 alone, and it is also possible to control the second pressurization chamber 4122 to provide airflow to the stairwell 411 alone. By controlling the airflow to the anteroom 420 and the stairwell 411 separately, the ventilation of the anteroom 420 or the stairwell 411 can be flexibly controlled.

[0045] Please see Figure 4 In one embodiment, the fire protection structure for the building also includes a precast L-shaped concrete slab 610, one side of which serves as a third partition wall 230, and the other side of which is attached to a second partition wall 220. The precast L-shaped concrete slab 610 is directly processed in the factory, which solves the problems of difficult on-site installation, rough interior of the second pressurization chamber 4122, high air supply resistance, and high air leakage rate. Specifically, the thickness of the precast L-shaped concrete slab 610 is 20mm.

[0046] Please see Figure 4In one embodiment, the fire protection structure for the building also includes a precast straight concrete slab 620, which is attached to the portion of the second partition wall 220 located in the first pressurization chamber 4121. The precast straight concrete slab 620 is directly processed in the factory, which solves the problems of difficult on-site installation, uneven interior of the first pressurization chamber 4121, high air supply resistance, and high air leakage rate. Specifically, the thickness of the precast straight concrete slab 620 is 20mm.

[0047] Furthermore, the second partition wall 220 can serve as one side of the precast L-shaped concrete slab 610 and the outer wall of the precast straight concrete slab 620. Therefore, in some embodiments, the second partition wall 220 may not be installed.

[0048] Please see Figure 1 and Figure 2 In one embodiment, the fire protection structure for the building further includes a first air volume regulator 510 and a second air volume regulator 520. The first air volume regulator 510 is disposed at the first opening 211 and is used to control the air flow through the first opening 211. The second air volume regulator 520 is disposed at the second opening 221 and is used to control the air flow through the second opening 221.

[0049] The first airflow regulator 510 located at the first opening 211 can control the airflow passing through the first opening 211, thereby controlling the airflow entering the anteroom 420; the second airflow regulator 520 located at the second opening 221 can control the airflow passing through the second opening 221, thereby controlling the airflow entering the stairwell 411; with this configuration, the airflow entering the anteroom 420 or stairwell 411 can be adjusted according to factors such as the flow of people in the stairwell 411 and the anteroom 420, the floor height, and the air freshness, ensuring that air circulates to all areas.

[0050] Optionally, the first air volume regulator 510 and the second air volume regulator 520 can be air outlets with adjustable airflow, such as mechanical pressurized air outlets, fan outlets, louvered air outlets, etc., without specific limitations.

[0051] In one embodiment, the first air volume regulating component 510 includes a first frame and a first 100-blade. The first frame is located at the first opening 211. At least two 100-blades are provided. All the 100-blades are parallel and spaced apart in the first frame. A first air inlet gap is formed between two adjacent 100-blades. All the 100-blades are rotatable so that the sides of two adjacent 100-blades that are close to each other can move closer or further away from each other, thereby narrowing or widening the first air inlet gap between two adjacent 100-blades.

[0052] The first frame is located at the first opening 211. At least two first louvers can rotate within the first frame, so that the sides of two adjacent louvers that are close to each other can move closer or further apart, making the first gust gap between two adjacent louvers narrower or wider, thereby making the airflow through the first frame smaller or larger, so as to control the airflow entering the anteroom 420. The installation is low-cost and reliable.

[0053] As an embodiment that can be implemented simultaneously with the above embodiments, the second air volume regulating component 520 includes a second frame and a second blade. The second frame is located at the second opening 221. There are at least two second blades. All the second blades are parallel and spaced apart in the second frame. A second air inlet gap is formed between two adjacent second blades. All the second blades can rotate so that the sides of two adjacent second blades that are close to each other can move closer or further away from each other, thereby narrowing or widening the second air inlet gap between two adjacent second blades.

[0054] Similar to the first air volume regulator 510, it will not be described in detail here.

[0055] Specifically, the first frame and the first louver are assembled to form the first louvered air vent, and the second frame and the second louver are assembled to form the second louvered air vent. When necessary, the first louvered air vent and the second louvered air vent can also be controlled to close to prevent external debris from entering the anteroom 420 and the stairwell 411.

[0056] During installation, the first louvered air vent can be set as a normally closed louvered air vent, and the second louvered air vent can be set as a normally open louvered air vent.

[0057] In one embodiment, the building has at least two floors, and at least two first partition walls 210 and second partition walls 220 are provided and are provided one-to-one with the floors. The first pressurization chamber 4121 is provided through all the floors, and all the first openings 211 are connected to the first pressurization chamber 4121. The second pressurization chamber 4122 is provided through all the floors, and all the second openings 221 are connected to the second pressurization chamber 4122.

[0058] The first pressurization chamber 4121 extends through all floors of the building. Thus, when the pressurization module 300 delivers airflow into the first pressurization chamber 4121, the airflow within it can enter the anteroom 420 of each floor through the first opening 211, ensuring that the anteroom 420 of each floor has residual pressure and preventing smoke from fire from entering the anteroom 420. Similarly, the second pressurization chamber 4122 extends through all floors of the building. Thus, when the pressurization module 300 delivers airflow into the second pressurization chamber 4122, the airflow within it can enter the stairwell 411 of each floor through the second opening 221, ensuring that the stairwell 411 of each floor has residual pressure and preventing smoke from fire from entering the stairwell 411. This configuration eliminates the need to sequentially install pressurization modules 300 on each floor while ensuring positive pressure in the anteroom 420 and stairwell 411 of each floor, reducing construction costs.

[0059] Furthermore, the pressurization module 300 can be installed on any floor of the building, such as the first or top floor, to reduce implementation costs.

[0060] Please see Figure 1 and Figure 3 In one embodiment, the pressurization module 300 includes a pressurization room 310, which is located on any floor. The pressurization room 310 is connected to the first pressurization chamber 4121 through a first air inlet 110, and is also connected to the second pressurization chamber 4122 through a second air inlet 120.

[0061] The pressurization room 310 can deliver airflow to the first pressurization chamber 4121 and the second pressurization chamber 4122 through the first air inlet 110 and the second air inlet 120 respectively. Since the first pressurization chamber 4121 and the second pressurization chamber 4122 are connected to each floor, by setting up the pressurization room 310 on any floor, it is possible to ensure that the anteroom 420 and stairwell 411 of each floor have positive pressure, thereby reducing construction costs.

[0062] Furthermore, the pressurization room 310 is usually equipped with pressurization devices, such as pressurizing fans and air boosters, and the pressurization room 310 can provide a certain degree of protection for these devices.

[0063] Please see Figure 1 and Figure 3 In one embodiment, the pressurization module 300 further includes a first pressurization duct 321 and a second pressurization duct 322. Both the first pressurization duct 321 and the second pressurization duct 322 are located in the pressurization room 310. The first pressurization duct 321 is connected to the first air inlet 110, and the second pressurization duct 322 is connected to the second air inlet 120.

[0064] The first pressurized air duct 321 is connected to the first air inlet 110 and delivers airflow into the first pressurized chamber 4121 through the first air inlet 110. The second pressurized air duct 322 is connected to the second air inlet 120 and delivers airflow into the second pressurized chamber 4122 through the second air inlet 120. This configuration ensures that the airflow is effectively delivered to the first pressurized chamber 4121 and the second pressurized chamber 4122, which is cost-effective and reliable.

[0065] Further, please refer to Figure 1 and Figure 3 One end of the first pressurized air duct 321 is connected to the first pressurized chamber 4121 through the first air inlet 110 on the outer wall 100, and the other end of the first pressurized air duct 321 passes through the wall of the pressurized room 310 and is connected to the outside, so that outside air is introduced into the first pressurized chamber 4121 through the first air inlet 110; similarly, one end of the second pressurized air duct 322 is connected to the second pressurized chamber 4122 through the second air inlet 120 on the outer wall 100, and the other end of the second pressurized air duct 322 passes through the wall of the pressurized room 310 and is connected to the outside, so that outside air is introduced into the second pressurized chamber 4122 through the second air inlet 120.

[0066] In one embodiment, at least two first pressurized air ducts 321 are provided to reliably deliver airflow to the first pressurized chamber 4121; at least two second pressurized air ducts 322 are provided to reliably deliver airflow to the second pressurized chamber 4122.

[0067] Please see Figure 1 and Figure 3 In one embodiment, the pressurization module 300 further includes a first pressurization fan 331 and a second pressurization fan 332, wherein the first pressurization fan 331 is connected to a first pressurization duct 321 and the second pressurization fan 332 is connected to a second pressurization duct 322.

[0068] The first pressurizing fan 331 can send outside air into the first pressurizing chamber 4121 through the first pressurizing duct 321, and the second pressurizing fan 332 can send outside air into the second pressurizing chamber 4122 through the second pressurizing duct 322. It is low in cost and has a reliable air supply effect.

[0069] Specifically, taking the first pressurizing fan 331 as an example, the first pressurizing fan 331 includes an impeller, a housing, and a motor. The impeller is rotatably disposed inside the housing, which is located on the inner wall of the first pressurizing duct 321. The motor can drive the impeller to rotate, thereby causing the air inside the first pressurizing duct 321 to flow, and then sending the air into the first pressurizing chamber 4121. The second pressurizing fan 332 is similar to the first pressurizing fan 331, and will not be described in detail here.

[0070] Please see Figure 1 and Figure 3 In one embodiment, the pressurization module 300 further includes a first fire damper 341 and a second fire damper 342, wherein the first fire damper 341 is disposed in the first pressurization duct 321 and the second fire damper 342 is disposed in the second pressurization duct 322.

[0071] By installing a first fire damper 341 in the first pressurized air duct 321 and a second fire damper 342 in the second pressurized air duct 322, it is possible to prevent the spread of fire after a fire occurs and to prevent toxic and high-temperature smoke from spreading and expanding through the first pressurized air duct 321 and the second pressurized air duct 322.

[0072] Specifically, taking the first fire damper 341 as an example, when a fire occurs in a building, if the temperature of the generated smoke is higher than the preset temperature, it indicates that the residents in the building have basically finished supplying the fire and the smoke is already on fire. At this time, the first fire damper 341 will automatically close to prevent the fire from spreading and to prevent the toxic and high-temperature smoke on fire from being discharged to the outside through the first pressurized air duct 321 to cause pollution or spread of the fire. The second fire damper 342 is similar to the first fire damper 341, and will not be described in detail here.

[0073] Another embodiment of this application provides a building that includes a fire protection structure for the building as described in any of the above embodiments.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
