住宅楼面通常采用预制空心板,板与板之间下口宽度一般留有20毫米宽的板缝。在灌筑细石混凝土时,通常做法是先扎水泥纸,再灌细石混凝土。用水泥纸扎缝,影响楼板结构的整体性,施工也不方便。我们采用φ14钢筋制作灌缝工具(图1)施工,灌缝效果又快又好。具体灌缝做法如下:待预制板安装完毕,并对板缝进行浇水润湿后,在板上沿板缝倒一条细石混凝土,再用补缝工具兜缝,见图2,边灌缝插实,边移动工 Prefabricated hollow slabs are usually used for residential floors, and the width of the lower mouth between panels is generally 20 mm wide. When filling fine-grained concrete, it is common practice to tie cement paper first and then fine-grain concrete. Lacing with cement paper affects the integrity of the floor structure and the construction is inconvenient. We use the φ14 steel reinforcement filling tool (Fig. 1) for construction, and the effect of filling is fast and good. The specific method of filling seams is as follows: After the prefabricated panels are installed, and after the panel seams are wetted and wetted, a thin stone concrete is poured along the panel seams and then seamed with a seaming tool, as shown in Figure 2.
