青岛建工局于七月底试验成功一种不用钢筋水泥制做的,既轻便保温,又能承重的大型屋面板。 这种大型屋面板是用泡沫菱苦土和玻璃丝制成的。它具有高度的保温隔热效能,比一般采用的泡沫混凝土隔热保温效能高一倍多,承重能力亦超过原设计荷重,因此可以把原来作好承重的钢筋混凝土大型屋面板完全省去,建筑 At the end of July, the Qingdao Construction Industry Bureau successfully tested a large-scale roofing panel that was made without cement and was lightweight and heat-retaining. This large roofing board is made of foamed magnesite and glass wool. It has a high degree of thermal insulation performance, more than double the general use of foam concrete thermal insulation performance, load capacity also exceeds the original design load, so you can make a good load-bearing reinforced concrete large roof panels completely, construction
