预制水磨石窗台板的方法很多,这里介绍一种比较简单又容易掌握的方法。这种方法是将预制窗台板的石子浆与混凝土结为一体,一次完成。具体做法见图1～6。主要技术措施如下。一、对施工场地的要求预制窗台板制作应选择抹面平整光滑的混凝土场地。预制时先在安装模具的地面刷一道隔离剂。二、施工工艺及操作方法 There are many ways to prefabricate terrazzo sills. Here is a simpler and easier way to master them. This method integrates the grout of the prefabricated sill plate with the concrete and is completed at one time. Specific practices are shown in Figures 1 to 6. The main technical measures are as follows. First, the construction site requirements Prefabricated window sill production should be selected to smooth the smooth concrete surface. In the prefabrication, firstly apply a release agent to the floor where the mold is installed. Second, construction process and operation method
