大模板多层住宅结构,是指采用大模板施工工艺,在现场浇灌墙体混凝土,以形成住宅建筑的主体结构。我国从1974年开始试点建造以来,至1978年,据不完全统计,竣工面积已达三百多万平方米。今年,在各省市的应用有了进一步的推广,开工面积达六百万平方米之多。经过几年来的实践,大模板多层住宅结构,已从初期主体结构内外墙全现浇发展到内墙现浇、外墙砌砖,内墙现浇、外墙预制等三种主要形式。某些地区和施工部门,正在试点和少量建造的,还有外墙采用加气混凝土条板以及砌块等不同的做法。
The large formwork multi-storey residential structure refers to the use of a large formwork construction process to cast concrete on the site to form the main structure of a residential building. Since China started the pilot construction in 1974, by 1978, according to incomplete statistics, the completed area has reached more than 3 million square meters. This year, the application in various provinces and cities has been further promoted, with an area of more than 6 million square meters. After several years of practice, the large formwork multi-story residential structure has developed from the in-situ cast-in-place of the main body structure to the in-situ cast-in-place, exterior brick masonry, cast-in-place walls, and prefabricated external walls. Some areas and construction departments are piloting and construction of a small amount, as well as the use of aerated concrete slabs and blocks on the exterior wall.
