Description

[0002] With the rapid development of building technology and the social economy, new concepts, new technologies, new materials and new processes are being widely used in architectural design. Various buildings are becoming more and more creative, large-scale and multifunctional, with increasingly higher requirements for the continuous layout of internal spaces and larger areas. Once a fire occurs, it will cause significant losses to people and property.

[0003] To prevent the spread of fire and reduce casualties and property damage, existing technologies often incorporate fire compartments within continuous spaces of public buildings. These compartments prevent the fire from spreading to other parts of the building for a certain period. This effectively confines the fire to a specific area, minimizing losses, and also provides favorable conditions for safe evacuation and firefighting.

[0004] Currently, fire compartment design typically limits the number of fire compartments based on the size of the public building, allowing only a single fire compartment within the specified area. This design approach ignores the spatial characteristics and functional requirements of public buildings, while also failing to consider fire load conditions. It cannot meet the current societal demand for continuous spatial layouts and fire protection arrangements, and has gradually become a barrier to architectural development.

[0025] [First Embodiment] like Figure 1-2 The image shows a fire compartment design method for continuous spaces within public buildings, provided by the first embodiment of the present invention. Figure 1 As shown, it includes the following steps: S1: Identify the boundary range of continuous spaces within a public building, thereby determining the design scope of fire compartments for the entire public building; in step S1, the boundary range of continuous spaces within a public building is identified through boundary parameters, which include at least the location, length, width, and clear height of the continuous space; the location of the continuous space can be used to obtain the geographical coordinates of the continuous space within the public building, so as to divide fire compartments and formulate fire prevention measures based on the actual situation of the continuous space within the public building; S2: Determine the combustible parameters within the boundary area; In this embodiment, the combustible parameters within the boundary area include at least the type of combustible, the quantity of combustible, and the energy released by the combustion of combustible, so as to provide a theoretical basis for the calculation of the total fire load in the subsequent continuous space. At the same time, by determining the type of combustible, other additional hazards that may exist in the type of combustible can also be distinguished, such as volatile toxic substances, explosives, etc., thereby providing a theoretical basis for the calculation of the fire value of the subsequent fire compartment and helping to provide the corresponding fire prevention measures. S3: Calculate the total fire load in a continuous space based on combustible material parameters. In this embodiment, in step S3, the total fire load in the continuous space is calculated according to the following formula. :

[0026] In the formula, Total fire load in a continuous space, in MJ; Indicates the first Combustible materials; Indicates the total number of types of combustible materials; Indicates the first The energy released when a combustible material burns, measured in MJ; Indicates the first in a continuous space The quantity of various combustible materials; This represents the upper limit of the fire load that a continuous space can accommodate, expressed in MJ. Therefore, while ensuring that the fire load does not exceed the upper limit of the fire load that the current continuous space of the public building can accommodate, the total fire load in the current continuous space of the public building is calculated. ; S4: Based on the clear height of the space and the total fire load Determine the number of fire compartments; like Figure 2 As shown, the specific steps include: S41: Compare the clear height H of the continuous space with the first clear height threshold H1. If the clear height does not exceed the first clear height threshold, then calculate the total fire load of the continuous space. Compared with the first fire load threshold Compare the total fire loads. Not exceeding the first fire load threshold When determining to divide the continuous interior space of a public building into a single fire compartment, when the total fire load... Exceeding the first fire load threshold When determining the division of a continuous internal space of a public building into multiple fire compartments, the minimum number of fire compartments shall be no less than [amount missing]. Integer values; for example, when When the minimum number of fire compartments is 2, that is, at least two fire compartments are required, but more than two fire compartments can be divided according to the actual situation. S42: When the clear height H of the space exceeds the first clear height threshold H1, compare the clear height H of the continuous space with the second clear height threshold H2. If the clear height does not exceed the second clear height threshold, then calculate the total fire load of the continuous space. With the second fire load threshold Compare the total fire loads. Not exceeding the second fire load threshold When determining to divide the continuous interior space of a public building into a single fire compartment, when the total fire load... Exceeding the second fire load threshold When determining the division of a continuous internal space of a public building into multiple fire compartments, the minimum number of fire compartments shall be no less than [amount missing]. Integer values; S43: When the clear height H of the space exceeds the second clear height threshold H2, compare the clear height H of the continuous space with the third clear height threshold H3. If the clear height does not exceed the third clear height threshold, then calculate the total fire load of the continuous space. With the third fire load threshold Compare the total fire loads. Not exceeding the third fire load threshold When determining to divide the continuous interior space of a public building into a single fire compartment, when the total fire load... Exceeding the third fire load threshold When determining the division of a continuous internal space of a public building into multiple fire compartments, the minimum number of fire compartments shall be no less than [amount missing]. Integer values; S44: When the clear height H of the space exceeds the third clear height threshold H3, compare the clear height H of the continuous space with the fourth clear height threshold H4. If the clear height does not exceed the fourth clear height threshold, then calculate the total fire load of the continuous space. With the fourth fire load threshold Compare the total fire loads. Not exceeding the fourth fire load threshold When determining to divide the continuous interior space of a public building into a single fire compartment, when the total fire load... Exceeding the fourth fire load threshold When determining the division of a continuous internal space of a public building into multiple fire compartments, the minimum number of fire compartments shall be no less than [amount missing]. Integer values; S45: When the clear height H of a space exceeds the fourth clear height threshold H4, the continuous space inside the public building is divided into multiple fire compartments, and the minimum number of fire compartments is not less than [a certain value]. Integer value.

[0027] When determining the division of a continuous interior space of a public building into multiple fire compartments, the minimum number of fire compartments is taken as... The integer value of , where, Total fire load; For the first Fire load threshold; this is because, after determining the clear height of the space and the corresponding clear height threshold, the greater the total fire load in a continuous space, the more dangerous it is. Therefore, based on the fire load threshold... Determine the specific number of fire compartments within the total fire load. Not exceeding the corresponding fire load threshold When the total fire load is low, dividing the area into one fire compartment is sufficient; however, when the total fire load is high... Exceeding the corresponding fire load threshold The more the fire exceeds the limit, the more dangerous the situation becomes, and the more fire compartments need to be created. This is used to determine the number of fire compartments corresponding to different fire load thresholds (rounded up).

[0028] Unlike existing design methods that only consider the area of ​​public buildings to determine a single fire compartment, the clear height of a space not only reflects the spatial characteristics and functional requirements of a public building, but also means the following for public buildings: 1) Greater fire risk: The higher the ceiling height, the larger the internal space, and the greater the possibility of storing flammable materials. At the same time, due to the need for ceiling lighting, the range and length of electrical circuits are larger and longer, thus making public buildings more likely to be subject to fire. 2) Larger fire scale: The higher the net height of a space, the larger its internal storage space, and therefore the higher the flame height and the wider the fire coverage area once a fire occurs. 3) Faster spread speed: The higher the net height of a space, the larger its internal space, and therefore the higher its internal air content. At the same time, due to the increase in other flammable materials such as electrical circuits or curtains laid on the top, the fire will spread faster. 4) Greater additional hazards: Since there may be other additional hazards among the types of combustible materials, such as volatile toxic substances and explosives, the higher the net height of the space, the larger the internal storage space, and the higher the possibility of the above-mentioned additional hazards. 5) Greater fire losses: The higher the net height of a space, the larger its internal storage space, and therefore the greater the casualties and property losses that will occur in the event of a fire.

[0029] Therefore, when dividing fire compartments, it is necessary to select the clear height of the space as a design indicator. Compared with the single area indicator, it can directly and accurately characterize the fire hazard in the building, thus providing a more scientific and reasonable technical guidance for the division of fire compartments and breaking the limitation of the existing fire compartment division according to a fixed upper limit value.

[0030] Based on this, after determining the range of the net height of the continuous space of a public building by comparing it with the corresponding preset net height threshold, the total fire load value of the current continuous space of the public building is then compared with the corresponding fire load threshold. This allows both the net height and the total fire load to be used as design indicators, taking into account both the spatial characteristics and functional requirements of the public building and its fire load status, thus meeting the current societal needs for continuous spatial layout and fire prevention arrangements. As a preferred embodiment, in this example, the first net height threshold is 6m, the second net height threshold is 9m, the third net height threshold is 12m, and the fourth net height threshold is 18m; the first fire load threshold is 1 million MJ, the second fire load threshold is 2 million MJ, the third fire load threshold is 4 million MJ, and the fourth fire load threshold is 8 million MJ. Those skilled in the art can also adjust the corresponding net height threshold and fire load threshold to other values ​​according to actual needs to meet the comparison requirements of the net height and total fire load of different continuous spaces in public buildings. S5: Calculate the fire value of the divided fire compartments; In step S5, the fire value of the divided fire compartment is calculated according to the following formula: ; In the formula, For the division of fire compartments Fire data; Fire compartment Total fire load; Fire compartment Clear height of space; Fire compartment The total number of types of combustible materials inside; Fire compartment The quantity of combustible materials inside; Additional hazard value; These are the corresponding weighting coefficients.

[0031] It is worth noting that the additional hazard value in the formula in this embodiment... This indicates other potential hazards that may exist within the types of combustible materials, such as volatile toxic substances and explosives; thus, it influences the calculation and division of each fire compartment. When calculating fire values, the fire compartment should be considered simultaneously. The corresponding clear height and total fire load of the space are taken into account, while also taking into account the fire compartment. The calculation includes the total number and quantity of combustible materials inside the fire compartment. In addition, it takes into account the potential hazards that other additional hazards may pose during a fire. This makes the calculated fire values ​​of the fire compartment closer to the actual situation during a fire, thus ensuring the effective and accurate implementation of subsequent fire protection levels and fire prevention measures.

[0032] S6: Determine the fire protection level of the divided fire compartments based on fire data; including the following steps: S61: Sort the fire values ​​of each fire compartment from highest to lowest; S62: The fire compartments corresponding to the fire values ​​at the top of the ranking are designated as high fire protection level, and the fire compartments corresponding to the fire values ​​at the bottom of the ranking are designated as low fire protection level. In this embodiment, the fire resistance level can be represented by numerical labels, letter labels, or text labels. For example, the fire resistance level from high to low can be represented by fire resistance level 1, fire resistance level 2, fire resistance level 3, etc. (numerical labels), or by fire resistance level I, fire resistance level II, fire resistance level III, etc. (letter labels), or by high fire resistance level, medium fire resistance level, low fire resistance level, etc. (text labels). Different colors can also be used to indicate the fire resistance level, for example, red can be used to mark high fire resistance level and green can be used to mark low fire resistance level. S7: Provide corresponding fire prevention measures for different fire protection levels of fire compartments; the fire prevention measures provided in step S7 include at least configuring smoke and temperature sensors, configuring alarm devices, configuring fire-fighting equipment, and configuring fire escape routes; accordingly, the fire prevention measures can be set according to the different fire protection levels of fire compartments. For example, for fire compartments with high fire protection levels, smoke and temperature sensors with higher accuracy or wider detection range can be provided to improve the accuracy and timeliness of fire prediction. More fire escape routes or wider passageways can also be provided for fire compartments with high fire protection levels to further improve the possibility and efficiency of personnel escape during a fire.

[0033] S8: Verify the effectiveness of fire compartments and their fire protection measures through numerical simulation: For the defined fire compartments and the corresponding fire protection measures provided for them, a building fire safety numerical simulation verification program is introduced to verify the defined fire compartments and their corresponding fire protection measures. The specific steps include: S81: Construct a numerical model of a public building and set the corresponding total fire load for it; S82: Divide fire compartments in the model according to the design method and provide corresponding fire protection measures for each fire compartment; S83: Conduct fire numerical simulations to analyze the dynamic changes in the fire development process, temperature field, velocity field, visibility, and key gas concentrations (such as O2, CO, CO2, etc.) within public buildings, in order to verify the effectiveness of the divided fire compartments and their corresponding fire prevention measures, thereby ensuring building fire safety in a more scientific and reliable manner.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
