MANUFACTURING METHOD OF PRECAST CONCRETE PRODUCT
PROBLEM TO BE SOLVED: To provide a manufacturing method of a precast concrete product having a fine surface finishing state.SOLUTION: A manufacturing method of a precast concrete product comprises: an application process to attach a curing sheet 3 on a formwork 1 for placing concrete; a concrete placing process to place concrete 5 in the formwork 5 with the curing sheet 3 attached on an inner surface of the formwork 1; a compaction process to manufacture a concrete product 5a by compacting the concrete 5 placed in the formwork 1 in the concrete placing process using at least either vibration or pressurization; and a formwork removing process to remove the formwork with the curing sheet remained on a surface of the concrete product. The curing sheet used in the concrete placing process is impermeable.
【課題】表面の仕上がり状態が良好なプレキャストコンクリート製品の製造方法を提供する。【解決手段】 プレキャストコンクリート製品の製造方法は、コンクリート打設用の型枠１に養生シート３を貼り付ける貼付け工程と、型枠１の内面に養生シート３が貼り付けられた状態で型枠１内にコンクリート５を打設する打設工程と、打設工程で型枠１内に打設されたコンクリート５を振動及び加圧の少なくとも一方を用いて締固めし、コンクリート製品５ａを形成する締固め工程と、締固め工程の後、養生シートをコンクリート製品の表面上に残置したまま型枠を脱型する脱型工程とを備え、打設工程等において用いる養生シートは非透水性である。【選択図】図１
