我们结合杭州某厂生活区职工住宅工程,试用了横墙承重的预制大跨度钢筋混凝土空心楼板(屋盖)。该试验性住宅(图1)为单元内廊式三层混合结构,建筑面积为792平米,它的特点是承重结构与围护结构分开,建筑平面布置得较为自由合理,同时还具有平面系数较高、房屋自重较轻等优点。现将设计和施工中的一些情况分述如下。 We have combined prefabricated large-span reinforced concrete hollow floor slabs (house roofs) with load-bearing cross walls under a residential house project in a residential area of ​​a factory in Hangzhou. The experimental house (Fig. 1) is a three-story hybrid structure with a unit inside gallery, with a construction area of ​​792 square meters. It is characterized by the separation of the load-bearing structure and the envelope structure, the layout of the building plane is relatively free and reasonable, and also has a plane factor. High, light weight and other advantages of the house. Some of the design and construction are now described as follows.
