雖然臨時性活動板房已被大量應用,但國內外對這種建筑結構的防火性能研究很少,這樣導致活動板房的防火性能得不到改善,其事故頻繁、損失不斷發(fā)生、隱患遲遲得不到解決,造成不良的社會影響,隨著以人為本、理念的深人和對資源環(huán)境的長遠考慮,對其進行防火性能的基礎研究具有重要的實際應用價值。
Although temporary prefabricated houses have been widely used, there is little research on the fire safety performance of this building structure at home and abroad, which leads to the failure to improve the fire safety performance of prefabricated houses. Its frequent accidents, frequent losses, and potential safety hazards have not been solved, resulting in adverse social impact. With the deepening of people-oriented and environmental protection concepts and long-term consideration of resources and environment, It has important practical application value to conduct basic research on its fire protection performance.
濟南活動板房材料使用并不合理,大部分活動板房的圍護板材采用彩色鋼板和EPS或聚氨醋芯材所組成的彩鋼夾芯板,EPS芯材為硬質泡沫塑料,較易燃燒,而且活動板房一般采取空間直接相連的安裝方式,著火后容易形成空腔,產(chǎn)生煙囪效應并迅速橫向蔓延,使得施工現(xiàn)場火災事故頻繁。
The use of materials for movable plank houses in Jinan is not reasonable. The enclosure panels of most movable plank houses are color steel sandwich panels composed of color steel plates and EPS or polyurethane core materials. EPS core materials are hard foam plastics, which are easy to burn. In addition, movable plank houses are generally installed in a way that the space is directly connected. After the fire, it is easy to form a cavity, produce a chimney effect and quickly spread horizontally, making the construction site fire accidents frequent.
然而活動板房是施工單位主要使用的房屋,它的性能關系到全國幾千萬農(nóng)民工的生命?;顒影宸恳话忝芗褂茫湎涝O施幾乎沒有,疏散困難,一旦發(fā)生事故,后果不堪設想。
However, prefabricated houses are mainly used by construction units, and their safety performance is related to the life safety of tens of millions of migrant workers across the country. The prefabricated house is generally used intensively, and its fire fighting facilities are almost non-existent. It is difficult to evacuate. Once an accident occurs, the consequences are unimaginable.
經(jīng)對活動板房用材的性能進行分析,以及活動板房用材與相關規(guī)范對比,結合活動板房的臨時性、活動性、性、簡易性、可周轉使用、低成本等特點,其與性民用建筑存在較大差別,不宜直接套用針對性民用建筑防火的規(guī)范來管理,應根據(jù)其本身的結構特點及使用環(huán)境進行研究。
Based on the analysis of the performance of the materials used in the prefabricated house and the comparison of the materials used in the prefabricated house with the relevant specifications, combined with the characteristics of the temporary, mobile, environmental protection, simplicity, recyclability, low cost and other characteristics of the prefabricated house, it is quite different from the permanent civil buildings. It is not suitable to directly apply the specifications for the fire safety of the permanent civil buildings to manage, but should be studied according to its own structural characteristics and use environment.
其防火的應為“防消結合,疏散為主”,耐火極限宜考慮結構的整體性能,采用防火性能化設計方法對其設計。由于活動板房結構、用途及內部可燃物的數(shù)量和分布情況均不一樣,其居住者或使用者的條件也存在很大差異,因此按照指令性規(guī)范統(tǒng)一給定的設計參數(shù)所做出的設計方案,并不一定是科學、合理、有效的。
The focus of fire prevention should be "combination of fire prevention and evacuation". The overall performance of the structure should be considered in the fire resistance limit, and the performance-based design method should be adopted for its design. Because the structure, purpose, quantity and distribution of combustible materials inside the prefabricated house are different, and the conditions of its occupants or users are also very different, the design scheme made according to the design parameters uniformly given in the mandatory specifications is not necessarily scientific, reasonable and effective.
根據(jù)活動板房的結構、用途和內部可燃物等方面的具體情況,由設計者根據(jù)活動板房的各個不同空間條件、功能條件及其他相關條件,自由選擇為達到消防目的而應采取的各種防火措施,并將其有機地組合起來,構成活動板房的總體防火設計方案。
According to the specific conditions of the structure, use and internal combustibles of the prefabricated house, the designer can freely choose various fire prevention measures to achieve the fire safety purpose according to the different space conditions, functional conditions and other relevant conditions of the prefabricated house, and organically combine them to form the overall fire safety design scheme of the prefabricated house.
然后用已開發(fā)出的工程學方法,對活動板房的火災危險性和危害性進行定量的預測和評估,從而得到優(yōu)化的防火設計方案,為活動板房提供合理的防火設計和評估方法。更多相關內容就來我們網(wǎng)站
