The invention discloses a PC (precast concrete) component production process and a device for lifting a PC component, and relates to the technical field of PC component production. The purpose of producing the PC component is achieved. According to the key points of the technical scheme, the PC component production process includes the steps that step one, formwork matching and installation are carried out; step two, reinforcing mesh pieces are installed, and surface concrete is poured; step three, insulation boards, reinforcement cages, supporting points and embedded parts are installed; stepfour, concrete is poured, curing is carried out, formworks are removed, wherein the component is cured by low-temperature steam, the steam curing is carried out with four stages of standstill, heating, constant temperature and cooling, standstill is calculated from the full completion of concrete pouring and vibrating, the heating rate is less than or equal to 15DEG C/h, the temperature during the constant temperature period is 55+/-2DEG C, the cooling rate should be less than or equal to 10DEG C/h, and steam curing is described more specifically in paragraph of mode of carrying out the invention; and step 5, the component is lifted.
本发明公开一种PC构件的生产工艺以及用于PC构件起吊装置,涉及PC构件生产技术领域,达到能够生产PC构件的目的,其技术方案要点是:步骤一、配模、安装模板;步骤二、钢筋网片安装、面层混凝土浇筑;步骤三、保温板安装、钢筋骨架安装、支撑点、埋件安装;步骤四、浇筑混凝土、养护、拆模;其中构件采用低温蒸汽养护,蒸养分静停、升温、恒温和降温四个阶段,静停从混凝土全部浇捣完毕开始计算,升温速度不大于15℃/h;恒温时段温度55±2℃;降温不宜大于10℃/h,蒸养为:步骤五、构件起吊。
