我单位承建的北京中国丹麦医学生物学培训中心的教学试验楼和专家宿舍楼,建筑面积近4000平方米。根据设计要求,要在预制混凝土板上,现浇66毫米或80毫米厚的水泥炉渣混凝土保温隔热层及20毫米厚的水泥砂浆抹面层,上面铺设由丹麦进口的厚3毫米的聚氯乙烯卷材地面或软木地面。为确保水泥炉渣垫层及水泥炉渣抹面层不出现空鼓和裂缝,我们预先制定了一些施工措施,并先经小面积试验后才大面积施工。具体做法如下。
The teaching experiment building and expert dormitory building of the Beijing China-Danish Medical Biology Training Center constructed by our company has a construction area of nearly 4,000 square meters. According to the design requirements, a 66 mm or 80 mm thick concrete slag concrete insulation layer and a 20 mm thick cement mortar bedding shall be cast on a precast concrete slab with a 3 mm thick polychlorinated layer imported from Denmark. Vinyl coil flooring or cork flooring. In order to ensure that there is no emptying and cracks in the cement slag matting layer and the cement slag surface layer, we have preliminarily formulated some construction measures and conducted large-scale construction after a small area test. The specific approach is as follows.
