濟(jì)南活動(dòng)板房現(xiàn)在更多的則是采納噴涂防火涂料、防腐涂料,氟碳漆的法子庇護(hù)鋼布局。由于這類辦法的防火隔熱性能好,施工不受布局幾多形體限制,日常沒必要要增加幫忙法子步調(diào),且涂層風(fēng)致輕,還有必定的美不雅觀觀觀裝潢沾染沖動(dòng)等,因此得到了遍布的把持。
Jinan activity board room now more is to adopt spraying fire retardant coating, anticorrosive coating, fluorocarbon paint method to protect steel layout. Due to the good fire and heat insulation performance of this kind of method, the construction is not limited by the layout, there is no need to increase the pace of daily help method, and the coating is light, and there is a certain beauty, decoration and impulse, so it has been widely controlled.
隨著高樓大大廈的立起和修建高度的幾回再三提升,愈來愈多的人們開始垂青山東活動(dòng)板房,由于濟(jì)南活動(dòng)板房修建具備強(qiáng)度高、自重輕、抗震性能好、施工周期短、根柢費(fèi)用低、布局占用面積少和財(cái)產(chǎn)化程度諸多長處。
With the rise of high-rise buildings and the improvement of building height, more and more people begin to pay attention to the prefabricated houses in Shandong. Because of the advantages of high strength, light weight, good seismic performance, short construction period, low cost, less occupied area and high degree of property in the construction of prefabricated houses in Jinan.
但是較之混凝土布局,鋼布局的一個(gè)較著錯(cuò)誤謬誤即是便利導(dǎo)熱,當(dāng)鋼材表面溫度達(dá)到400℃以上,其強(qiáng)度和彈性模量將較著低落,而當(dāng)溫度達(dá)到600℃時(shí),彩鋼活動(dòng)房用鋼的強(qiáng)度幾乎為零。
However, compared with the concrete layout, the steel layout is more wrong, that is, convenient heat conduction. When the surface temperature of the steel reaches above 400 ℃, its strength and elastic modulus will be lower. When the temperature reaches 600 ℃, the strength of the steel used in the color steel activity room is almost zero.
濟(jì)南活動(dòng)板房裸鋼的耐火極限凡是只要15~30分鐘,依照咱國有關(guān)修建防火籌劃典范的需要,修建的告急承重構(gòu)件,如柱、梁、墻、樓板的耐火極限的需要,別離為0.5~3.0小時(shí)。我們已明文規(guī)定必須在鋼布局上采用防火辦法,并且要達(dá)到相應(yīng)的標(biāo)準(zhǔn)本事顛末過程才驗(yàn)收。
The fire resistance limit of bare steel in Jinan prefabricated house is usually only 15-30 minutes. According to the needs of China's fire prevention planning model, the fire resistance limit of emergency bearing components, such as columns, beams, walls and floors, is 0.5-3.0 hours. Our country has clearly stipulated that the fire prevention measures must be adopted in the steel layout, and the corresponding national standards must be met before acceptance.
