Description

Technical Field

[0001] This invention relates to the field of building fire protection design technology, and in particular to a method, device, equipment, medium and product for dividing fire compartments in old residential communities. Background Technology

[0002] With the acceleration of urban renewal, fire safety renovation of old residential areas has become an urgent problem to be solved. Existing fire prevention systems are mainly designed for new building areas, typically blocking fire spread by specifying fire separation distances between buildings or rigidly limiting the floor area or building area of ​​fire compartments. However, old residential areas often have characteristics such as high building density, solidified street patterns, and high requirements for preserving historical features, making it difficult for existing buildings to meet the fire separation distances required by new construction standards. Blindly applying current regulations would not only be costly but would also damage the original spatial structure and historical context of the historical district.

[0003] Furthermore, the fire resistance ratings of buildings in older residential communities are extremely diverse, with concrete buildings and brick-and-wood structures often built adjacent to each other. The actual fire load and spread risk vary significantly depending on the combination of buildings with different fire resistance ratings. Current technology lacks sophisticated assessment methods for this complex built environment, making it difficult to scientifically quantify the fire risk of mixed structures. This results in assessments that are either too conservative to be implemented or too lenient, creating hidden dangers. Simultaneously, current regulations lack standards for fire compartmentation in older residential communities at the street-level, failing to effectively address the fire prevention needs arising from the mutual influence of buildings within these communities. Summary of the Invention

[0004] The purpose of this invention is to provide a method, device, equipment, medium, and product for dividing fire-resistant zones in old residential communities. By constructing a two-level fire-resistant separation system of fire control zones and fire-resistant clusters, it can adapt to the fixed spatial structure of old residential communities and achieve a balance between fire safety and renovation feasibility. Furthermore, based on the fire resistance rating risk calculation method, it can scientifically quantify the differentiated fire risks when buildings of different fire resistance ratings are adjacent, thereby effectively solving the technical bottlenecks in the fire protection renovation of old residential communities.

Based on the floor area of ​​buildings with different fire resistance ratings within each fire protection cluster, the comprehensive fire risk index of each fire protection cluster is calculated, and the boundary of the fire protection cluster is adjusted according to the comprehensive fire risk index.

[0010] As an improvement to the above scheme, adjusting the boundary of the fire protection cluster according to the comprehensive fire risk index includes: If the overall fire risk index of the fire protection group is greater than the preset risk threshold, then some low fire resistance buildings within the fire protection group will be reclassified into adjacent fire protection groups until the overall fire risk index of the fire protection group is less than or equal to the preset risk threshold.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1 , Figure 1 This is a flowchart illustrating a preferred embodiment of a method for dividing fire compartments in old residential communities provided by the present invention. The method for dividing fire compartments in old residential communities includes: S1, acquire building data and community data of the target old residential area, and construct a spatial information database of the target area; S2, Based on the spatial information database, the target area is divided into several fire control zones according to natural and artificial boundaries; S3, based on the preset area threshold and multi-dimensional spatial functional constraints, divide each fire control zone into several fire protection clusters. S4. Calculate the comprehensive fire risk index of each fire protection group based on the floor area of ​​buildings with different fire resistance ratings within each fire protection group, and adjust the boundary of the fire protection group based on the comprehensive fire risk index. S5, Based on the adjusted fire protection clusters, generate the fire separation zone division result of the target old residential area; wherein, the fire separation zone includes the fire control zone and the fire protection clusters.

[0019] Specifically, this invention provides a method for dividing fire compartments in old residential communities. Old residential communities refer to those in cities or county towns (townships) that were built relatively early, are poorly maintained and managed, have inadequate municipal infrastructure, lack adequate community service facilities, and where residents have a strong desire for renovation. This invention first acquires building data and community data for the target old residential community, and then constructs a spatial information database for the target area based on the building data and community data. The building data includes the building's plan outline, location coordinates, number of floors, height, density, structural type, construction year, fire resistance rating, and building function. Through on-site surveying or existing topographic maps, the plan outline, location coordinates, number of floors, height, and density of each building in the target old residential community are acquired. Through on-site investigation or historical archive review, the structural type (e.g., reinforced concrete, brick-concrete, brick-wood, wood structure), construction year, fire resistance rating (classified as Level I, II, III, and IV according to current standards), and building function (residential, commercial, warehousing, public facilities, etc.) of each building are determined. The community data includes road network, road width, fire hydrant location, distribution of municipal fire hydrants, fire lane entrances and exits, population density, and historical fire data. Then, based on the spatial information database, the target area is divided into several fire control zones according to natural and artificial boundaries. According to preset area thresholds and multi-dimensional spatial functional constraints, several fire-resistant clusters are initially divided within each fire control zone as the smallest unit for controlling fire spread. After the initial division of fire-resistant clusters, the comprehensive fire risk index of each fire-resistant cluster is calculated based on the floor area of ​​buildings with different fire resistance ratings within each cluster. This is to assess the overall fire risk of the fire-resistant cluster, and the boundaries of the fire-resistant clusters are adjusted based on the comprehensive fire risk index. Finally, based on the adjusted fire-resistant clusters, the fire separation zone division results of the target old community are generated. The fire separation zone includes fire control zones and fire-resistant clusters. For example, the boundary lines between the final fire control zone and the fire protection cluster are drawn on the topographic map of the target area. Based on the actual situation of the fire protection cluster, the type (passage or firewall) and requirements (passage requirements and specific firewall requirements) of each isolation zone are clarified. A database of fire control zones and fire protection clusters is established, which includes information such as the building area, building composition, fire resistance rating distribution, and risk assessment value of each unit, thereby providing a basis for subsequent fire management.

[0020] This invention effectively addresses the technical bottlenecks in fire protection renovation of old residential communities by constructing a two-tiered fire separation system of fire control zones and fire-resistant clusters. First, this invention breaks through the rigid constraints of new construction standards, adapting to the solidified spatial fabric of old communities. While preserving the historical streetscape, it achieves a balance between fire safety and renovation feasibility through graded fire compartmentation. Second, the innovative fire resistance rating risk calculation method scientifically quantifies the differentiated fire risks when buildings of different fire resistance ratings are adjacent, avoiding the drawbacks of a one-size-fits-all approach. This prevents both oversights in high-risk area assessments and over-control of low-risk areas. Finally, by optimizing the division logic of fire-resistant clusters, it effectively isolates buildings with high fire loads, significantly improving the overall fire resistance of old communities at the street scale, and providing precise and efficient technical support for fire safety management in urban renewal.

[0021] As a preferred embodiment, the natural boundaries include mountains and river systems; the artificial boundaries include urban roads, square boundaries, green space boundaries, and firewalls; the building area of ​​each fire control zone is no more than 20,000 square meters, and each fire control zone is surrounded by a firebreak.

[0022] Specifically, in this embodiment of the invention, natural boundaries include mountains, river systems, etc., which have good fire-resistant isolation functions; artificial boundaries include urban roads, square boundaries, green space boundaries, firewalls, etc. When dividing a target area into several fire control zones based on natural and artificial boundaries, this embodiment of the invention prioritizes the use of natural and artificial boundaries as the boundaries of the fire control zones, with the building area of ​​each fire control zone not exceeding 20,000 square meters. It should be noted that the area threshold is set with reference to the current "General Code for Fire Protection of Buildings," which stipulates that "underground or semi-underground shops with a total building area greater than 20,000 square meters should be divided into multiple areas with a building area not exceeding 20,000 square meters, and the fire separation measures should be reliable and effective." Furthermore, factors such as building density, population density, historical fire data, and road accessibility can be comprehensively considered during the division to ensure that the fire control zone division facilitates subsequent fire protection work. After the fire control zones are divided, firebreaks can be set around each fire control zone. The net width of the firebreak should not be less than 4 meters, and priority should be given to utilizing horizontal firebreaks such as urban roads, streets, waterways, and squares. For space-constrained areas, firewalls can be used for separation, and the fire separation measures must be reliable and effective.

[0023] In a preferred embodiment, the multidimensional spatial functional constraints include: building functional zoning constraints, traffic accessibility constraints, fire protection facility coverage constraints, and spatial continuity constraints; the total floor area of ​​buildings within each fire-resistant cluster is no more than 2,500 square meters, and fire-resistant isolation zones are provided between the fire-resistant clusters.

[0024] Specifically, the multi-dimensional spatial functional constraints in this embodiment of the invention include: building functional zoning constraints, traffic accessibility constraints, fire protection facility coverage constraints, and spatial continuity constraints. In this embodiment, when initially dividing several fire-resistant clusters within each fire control zone according to preset area thresholds and multi-dimensional spatial functional constraints, the total floor area of ​​buildings within each fire-resistant cluster does not exceed 2500 square meters. The division of fire-resistant clusters simultaneously considers building functional zoning constraints, traffic accessibility constraints, fire protection facility coverage constraints, and spatial continuity constraints. For example, high-risk functional buildings (such as flammable goods warehouses, ground-floor mixed-use commercial and residential buildings) are separated from low-risk functional buildings (such as pure residential buildings). Large areas of brick-and-wood structure warehouses are designated as a separate cluster, and are strictly prohibited from being mixed with residential buildings in the same cluster. Using a 5-minute evacuation circle as a standard, it is ensured that there are evacuation passages with a width of not less than 4 meters within or at the boundary of the cluster, and that the distance from the farthest point within the cluster to the safe exit meets regulatory requirements (e.g., evacuation distances are reduced for buildings with low fire resistance ratings). Based on the service radius of fire protection facilities (e.g., a 150m protection radius for fire hydrants), ensure that each fire prevention cluster is equipped with fire protection facilities within or adjacent to its boundary to avoid blind spots. Respect the street-alley-courtyard fabric of older communities, and in principle, avoid crossing complete courtyard walls or alleyways to maintain the integrity of the original community structure and reduce demolition and reconstruction. After dividing the fire prevention clusters, firebreaks can be set up between them. These firebreaks include horizontal firebreaks (street passages, squares, etc.) and three-dimensional firebreaks (firewalls, etc.). The net width of the firebreak should not be less than 4 meters, with priority given to using horizontal firebreaks such as urban roads, streets, waterways, and squares. For areas with limited space, firewalls can be used for separation. The setting of firebreaks must comply with fire protection regulations to ensure that fires are effectively contained between clusters.

[0025] This invention constructs a two-level fire separation zone consisting of a fire control zone (building area ≤ 20,000 square meters) and a fire-resistant cluster (land area ≤ 2,500 square meters). It creatively applies the underground space zoning logic to form a fire control zone in high-density above-ground blocks, and applies the building fire zoning logic to form a fire-resistant cluster in high-density above-ground blocks, thus realizing the delineation of a two-level fire separation zone for fire protection in old residential areas.

[0026] As a preferred embodiment, the formula for calculating the comprehensive fire risk index is as follows: ; In the formula, R This indicates the overall fire risk index; A 1 、A 2 represents the floor area of ​​buildings with fire resistance ratings of Class I and Class II, respectively; A 3 indicates the floor area of ​​a building with a fire resistance rating of Class III; A4 indicates the floor area of ​​a building with a fire resistance rating of Class IV; a, b, c These represent the corresponding risk area thresholds.

[0027] Specifically, in this embodiment of the invention, after the initial division of fire-resistant clusters, the comprehensive fire risk index of each fire-resistant cluster is calculated based on the floor area of ​​buildings with different fire resistance ratings within each cluster. The calculation formula is as follows: ; In the formula, R This indicates the overall fire risk index; A 1 、A 2 represents the floor area of ​​buildings with fire resistance ratings of Class I and Class II, respectively; A 3 indicates the floor area of ​​a building with a fire resistance rating of Class III; A 4 indicates the floor area of ​​a building with a fire resistance rating of Class IV; a, b, c These represent the corresponding risk area thresholds.

[0028] It should be noted that the embodiments of the present invention take into account the strong fire resistance of Class I and II fire-resistant buildings (mainly reinforced concrete structures), meaning that when the entire fire-resistant cluster consists of Class I and II fire-resistant buildings, the floor area does not exceed 2500 square meters. a =2500. The fire risk is significantly increased in Class III fire-resistant buildings (mainly brick-and-wood structures), meaning that when an entire fire-resistant cluster consists of Class III fire-resistant buildings, the floor area should not exceed 1200 square meters. b =1200. Class IV fire-resistant buildings (mainly timber structures) pose the highest fire risk, meaning that when an entire fire-resistant cluster consists of Class IV fire-resistant buildings, the total floor area does not exceed 600 square meters. c =600. At this point, the formula for calculating the comprehensive fire risk index is: ; Furthermore, unlike simple clustering, the aforementioned weighted formula directly converts buildings of different fire resistance ratings, providing an easily identifiable and calculable fire risk assessment method. This invention is particularly suitable for the renovation of old residential areas containing historical buildings. Through the weighted formula assessment, more historical buildings with fire resistance ratings of level three and four can be preserved, thus avoiding large-scale demolition and construction caused by mechanically applying current regulations.

[0029] The embodiments of the present invention realize the scientific quantification of the overall fire risk of mixed building complexes and provide a mathematical basis for the flexible allocation of high-risk and low-risk buildings.

[0030] In another preferred embodiment, adjusting the boundary of the fire protection cluster according to the comprehensive fire risk index includes: If the overall fire risk index of the fire protection group is greater than the preset risk threshold, then some low fire resistance buildings within the fire protection group will be reclassified into adjacent fire protection groups until the overall fire risk index of the fire protection group is less than or equal to the preset risk threshold.

[0031] Specifically, in this embodiment of the invention, after calculating the comprehensive fire risk index of each fire protection group based on the floor area of ​​buildings with different fire resistance ratings within each fire protection group, it determines whether the comprehensive fire risk index of each fire protection group is greater than a preset risk threshold. In this embodiment of the invention, the risk threshold is set to 1. If the comprehensive fire risk index of the fire protection group is greater than the preset risk threshold, that is... R If the fire risk index is greater than 1, then some low-fire-resistance buildings (i.e., high-risk buildings) within a fire protection cluster will be reclassified into adjacent fire protection clusters until the overall fire risk index of the fire protection cluster is less than or equal to the preset risk threshold. R ≤1, which allows the overall risk of the fire-resistant cluster to be controlled within an acceptable range while respecting the existing building status quo.

[0032] This invention proposes a two-tiered fire separation zone delineation method for old residential communities. This method utilizes spatial identification (identifying and utilizing existing natural or artificial boundaries in the target area that serve as fire-resistant isolation), combined with zoning area rules and risk quantification models for risk verification and boundary correction. The method delineates fire control zones and fire-resistant clusters within these zones to curb the risk of large-scale fire spread. Fire isolation is achieved by further subdividing fire-resistant clusters with a floor area of ​​no more than 2,500 square meters, filling a technical gap in current regulations regarding fire separation zone delineation in old residential communities. Furthermore, to address the situation where different fire resistance ratings (Level I, II, III, and IV) are mixed within fire-resistant clusters in old residential communities, a risk assessment method for the fire resistance rating of buildings in these clusters is proposed, enabling a scientific and quantitative assessment of the fire risk of mixed building groups in old residential communities.

[0033] Accordingly, the present invention also provides a fire compartment division device for old residential communities, which can realize all the processes of the fire compartment division method for old residential communities in the above embodiments.
