某宾馆工地徒工小李正在楼板上浇灌混凝土,小李问工长周师傅:过去我们施工公共建筑时,楼面总是用组合式钢模板作现浇混凝土板,或直接铺设空心板。而这次是先做好混凝土薄板,把薄板当模板,上面再浇筑混凝土,这样做,在预制厂有一道预制工序,运到现场又有一道现浇工序,比采用组合式钢模板或空心板要麻烦得多!为什么要这样做呢?叠合楼板有什么特点吗?周师傅:你这个问题提得很好! A hotel worker, Xiao Li, is pouring concrete on the floor. Xiao Li asks the foreman: During the construction of public buildings in the past, floors were always made of cast-in-place concrete panels or hollow slabs. This time, the concrete slabs were first made, the slabs were used as templates, and the concrete was placed on the top. In doing so, there was a prefabrication process in the prefabrication plant, and a cast-in-place process was performed on the site. This was a composite steel template or hollow slab. It’s much more troublesome! Why do you want to do this? What are the characteristics of the overlapping floor? Master Zhou: You raise this question very well!
