这是甘肃省建筑标准设计办公室、省建七公司、省建科所在多层大板建筑和内浇外砌建筑体系基础上研究成功的。现已形成一定生产能力,并有十几个省、市、区采用。与同类(六层)砖混结构相比它施工速度快,工期缩短1/3,现场用工减少1/4;手工砌砖减少58%;湿作业少,墙面抹灰减少80%;内墙减薄,使用面积有所增加,增加居住面积约6%;施工现场占地减少;易于冬季施工;每平方米钢筋、水泥
This is based on the success of the construction standard design office of Gansu Province, the Provincial Construction Seven Corporation, and the provincial construction department on the basis of the multi-storey slab building and the pour-in exterior masonry building system. A certain amount of production capacity has now been established, and more than a dozen provinces, municipalities and districts have adopted it. Compared with the same type (six-layer) brick-concrete structure, it has a faster construction speed, shortens the construction period by 1/3, reduces on-site labor by 1/4, reduces manual bricklaying by 58%, reduces wet work, and reduces wall plaster by 80%. Thinning, increase in use area, increase living area by about 6%; decrease in construction site area; easy construction in winter; reinforcement and cement per square meter
