The invention provides a construction method for precast slabs. The construction method comprises the following steps that S1, during installation, a precast beam formwork and a floor formwork are firstly erected on a floor, and a reinforcement beam is installed between the beam formwork and the floor formwork; S2, a reinforcement cage is arranged between the beam formwork and the floor formwork,and the reinforcement cage is arranged on the upper part of the reinforcement beam; S3, a plurality of precast slabs are arranged on the floor formwork at equal intervals; S4, waterproof structures for waterproof are arranged in the joints of every two precast slabs, when the precast slabs are installed, an auxiliary stretching mechanism for stretching a gap in the inner side of the reinforcementcage is arranged on the outer side of the beam formwork; and S5, the inner side of the reinforcement cage is pulled to the outside through the action of the auxiliary stretching mechanism, so that thereinforcement cage is pulled out of the gap, and the truss reinforcement of the precast slabs are conveniently embedded between the reinforcement cage and the reinforcement beam. According to the construction method, the construction period of the floor can be effectively shortened, and the plate joint is waterproofed.
本发明提供了一种预制板施工方法包括以下步骤：步骤S1、安装时，先在楼层上架设预制梁模板和楼层模板，在梁模板和楼层模板之间安装钢筋梁；步骤S2、梁模板和楼层模板之间设置有钢筋笼，且所述钢筋笼设置于所述钢筋梁上方；步骤S3、楼层模板上等距离设置有多个预制板；步骤S4、两两预制板接缝内设置有用于进行防水的防水结构，在安装预制板时，在梁模板外侧设置有用于将钢筋笼内侧拉开间隙的辅助拉伸机构；步骤S5、通过辅助拉伸机构的作用将钢筋笼的内侧拉向外侧，使得钢筋笼被拉出缝隙，便于预制板的桁架筋嵌入所述钢筋笼与钢筋梁之间；本发明能够有效减少楼板的施工周期，且对板材接缝进行防水。
