工業建筑設計要點

   隨著社會經濟和科學技術的不斷發展,工業廠房越來越多樣化且面積和功能復雜程度也不斷增大,這使得廠房的防火設計逐漸受到重視并提出了更高的要求雷速体育网,從而達到保障工業廠房的消防安全減少火災隱患的目的雷速体育网。那么,小編今天就對廠房的一些防火設計要點做以下總結雷速体育网。

  其一,我們要對建筑物生產的火災危險性分類做出正確的定義。根據《建筑設計防火規范》GB50016-2014第3.1.1條規定生產的火災危險性應根據生產中使用或產生的物質性質及其數量等因素劃分,可分為甲、乙、丙雷速体育网、丁、戊類并應符合表3.1.1的規定。該條文實質上是對生產的火災危險性分類原則做出了規定,比如生產中使用的物質,劃分甲、乙、丙類液體閃點的基準、可燃氣體爆炸下限的確定基準、甲類火災危險性的生產特性、乙類火災危險性的生產特性、丙類火災危險性的生產特性雷速体育网、丁類火災危險性的生產特性雷速体育网、戊類火災危險性的生產特性雷速体育网。
  其二,我們要按要求確定建筑的耐火等級。它的確定可依據《建筑設計防火規范》GB50016-2014第3.2小結,其中3.2.1條規定廠房的耐火等級可分為一雷速体育网、二、三、四級并確定相應建筑構件的燃燒性能和耐火極限,3.2.2條規定高層廠房,甲雷速体育网、乙類廠房的耐火等級不應低于二級雷速体育网,建筑面積不大于300m2的獨立甲、乙類單層廠房可采用三級耐火等級的建筑雷速体育网,3.2.3條規定單、多層丙類廠房和多層丁、戊類廠房的耐火等級不應低于三級等等條文均作出了相應規定。
  其三,我們要合理劃分建筑的防火分區雷速体育网,對每個防火分區的面積進行嚴格的控制。根據《建筑設計防火規范》GB50016-2014第3.3.1條廠房的層數和每個防火分區的最大允許建筑面積應符合表3.3.1的規定。
  其四,我們要控制廠房之間的防火間距及廠房的安全疏散。這在《建筑設計防火規范》GB50016-2014第3.4小結和3.7小結做出了規定。
  最后雷速体育网,工業廠房的防火設計是個較為復雜的問題,有許多需要注意的事項和值得探討的內容雷速体育网。在設計的過程中應嚴格地貫徹防火規范的要求雷速体育网,從全局出發,統籌兼顧,積極采取行之有效的防火技術,做到保障安全、方便使用雷速体育网、經濟合理。
    With the continuous development of social economy and science and technology, the industrial plant is becoming more and more diversified and the area and function complexity are also increasing, which makes the fire protection design of the plant gradually attracted attention and put forward higher requirements, so as to achieve the purpose of ensuring the fire safety of the industrial plant and reducing the fire hazards. In that case, today, Xiaobian summarizes some key points of fire protection design of the plant.
    First, we need to make a correct definition of the fire risk classification of building production. According to Article 3.1.1 of code for fire protection design of buildings (gb50016-2014), the fire risk of production shall be divided into class A, class B, class C, class D and class E according to the nature and quantity of substances used or produced in production, and shall conform to the provisions of table 3.1.1. In essence, this article has made provisions on the classification principle of fire risk in production, such as the substances used in production, the basis for dividing the flash point of class A, B and C liquid, the basis for determining the lower explosion limit of combustible gas, the production characteristics of class a fire risk, the production characteristics of class B fire risk, the production characteristics of class C fire risk, and the production of class D fire risk Characteristics, production characteristics of class E fire hazard.
    Secondly, we need to determine the fire resistance rating of the building according to the requirements. It can be determined according to the summary of 3.2 in code for fire protection design of buildings (gb50016-2014), in which the fire resistance rating of plant specified in 3.2.1 can be divided into 1, 2, 3 and 4 levels, and the combustion performance and fire resistance limit of corresponding building components can be determined. In 3.2.2, the fire resistance rating of high-rise plant, class A and class B plant shall not be lower than class II, and the building area shall not be greater than 300m2 for independent class A and class B single floor Buildings with three-level fire resistance rating can be used in the plant. Article 3.2.3 stipulates that the fire resistance rating of single and multi-layer class C plants and multi-layer class D and class E plants shall not be lower than Class III and other articles have made corresponding provisions.
    Thirdly, we should reasonably divide the fire zones of buildings and strictly control the area of each fire zone. According to Article 3.3.1 of code for fire protection design of buildings (gb50016-2014), the number of floors of the plant and the maximum allowable building area of each fire compartment shall meet the requirements of table 3.3.1.
    Fourthly, we need to control the fire separation between the plants and the safe evacuation of the plants. This is stipulated in summary 3.4 and summary 3.7 of code for fire protection design of buildings (gb50016-2014).
    Finally, the fire protection design of industrial plant is a complex problem, which has many matters needing attention and contents worth discussing. In the process of design, it is necessary to strictly implement the requirements of fire prevention code, start from the overall situation, take overall consideration, and actively adopt effective fire prevention technology to ensure safety, convenient use and economic rationality.
