The invention belongs to the technical field of building material manufacturing, and particularly relates to a method for manufacturing a reinforced concrete precast slab. The method includes the following steps that first, molds are installed; second, reinforcing steel bars are also installed; third, concrete is poured; and fourth, a concrete layer is cured, and after the concrete layer is poured, a concrete layer vibrating device is used for vibrating the concrete layer; and after being subjected to wiping pressure, the surface of the concrete layer is covered with felt, and watering curingis further carried out. By adoption of the method for manufacturing the reinforced concrete precast slab in the invention, when the poured concrete layer is vibrated, a second limiting rod is sleevedwith different numbers of rubber rings, the lowest position of a second mounting base on the second limiting rod is adjusted, and therefore the lowest position of a vibrating bar can be adjusted, themaximum depth for the vibrating bar to be inserted into the concrete layer can be controlled accurately, and the phenomenon that the end of the vibrating bar touches the upper surface of a bottom formwork is avoided.
本发明属于建材制造技术领域，具体涉及一种钢筋混凝土预制板制造方法，包括以下步骤：步骤一、安装模具；步骤二、安装钢筋；步骤三、浇注混凝土；步骤四：混凝土层养护：混凝土层浇注完成后，用混凝土层振捣装置对混凝土层进行振捣；待混凝土层表面收浆后用毛毡覆盖混凝土层表面，并进行洒水养护。采用本发明提供的钢筋混凝土预制板制造方法对浇筑完成后的混凝土层进行振捣时，通过在第二限位杆上套设不同数量的橡胶圈，调整第二安装座在第二限位杆上所能达到的最低位置，从而调整振捣棒所能达到的最低位置，进而实现了对振捣棒插入混凝土层最大深度的精确控制，避免了振捣棒端部触碰到底模板上表面的情况发生。
