石棉水泥空心保溫板是一种薄壁空心的輕型构件,它是用石棉水泥薄板和保溫材料制成的,可以用作大型工业厂房、仓庫等的保溫屋頂。这种保溫板具有以下优点: 1.輕:石棉水泥空心保溫板每平方米重70公斤左右,比一般带有保溫层的泡沫混凝土屋盖还輕一半以上,比槽形板屋盖輕三分之二。2.节約鋼材,降低造价:石棉水泥板有很高的机械强度:抗弯曲强度达250公斤/平方厘米;抗拉强度平均在80公斤/平方厘米以上。可是石棉水泥板中沒有鋼筋,它是用部分中等的石棉纖維配筋的,比其他鋼筋混凝土屋面板每平方米可以节省7公斤左右的鋼材,这还不包括由于承重結构断面减小所节约的鋼材。另一方面,保溫板的价格便宜,大批生产,每平
Asbestos cement hollow thermal insulation board is a kind of thin-wall hollow light component. It is made of asbestos cement sheet and insulation material, and can be used as insulation roof of large industrial plants and warehouses. This kind of insulation board has the following advantages: 1. Light: Asbestos cement hollow insulation board weighs about 70 kilograms per square meter, which is more than half of the foamed concrete roof with insulation layer, three times lighter than the grooved plate roof two. 2. Save steel and reduce cost: Asbestos cement board has high mechanical strength: flexural strength up to 250 kg/cm2; tensile strength averaged above 80 kg/cm2. However, the asbestos-cement board is not reinforced, and it is reinforced with some medium-sized asbestos fibers, which saves about 7 kg of steel per square meter compared to other reinforced concrete roof panels. This does not include the savings due to the reduction in cross section of the load-bearing structure. Steel. On the other hand, the insulation board is cheap, mass production, per flat
