METHOD FOR PRODUCING PRECAST CONCRETE MEMBER, AND PRECAST CONCRETE MEMBER
To provide a method for producing a precast concrete member, when a precast concrete member is formed by spraying concrete, capable of easily securing the smoothness of the member surface.SOLUTION: A method for producing a precast concrete member having a cavity at the central part of the cross-section comprises a mounting step S2 where a reinforcing cage composed of a main reinforcement and a shear reinforcement is mounted on the upper face of a bottom plate, a concrete spray step S4 where concrete is sprayed to a partition material arranged so as to be stored at the inside of a reinforcing cage from the outside of the reinforcing cage to form an open cross-section concrete layer in which the face of the bottom plate side is released and a leveling step S5 where the surface of the concrete layer is leveled. In the mounting step S2, the reinforcing cage is mounted in such a manner that the main reinforcement is made parallel to the plate face of the bottom plate. Further, the partition material is arranged in such a manner that the bottom plate side is opened.SELECTED DRAWING: Figure 2
【課題】吹付けコンクリートによりプレキャストコンクリート部材を形成する場合において、簡易に部材表面の平滑さを確保することを可能としたプレキャストコンクリート部材の製造方法を提案する。【解決手段】断面中心部に空洞を有するプレキャストコンクリート部材の製造方法であって、主筋とせん断補強筋で構成される鉄筋かごを底板の上面に載置する載置工程Ｓ２と、鉄筋かごの内側に納まるように配設された仕切材に対して鉄筋かごの外側からコンクリートを吹き付け、底板側の面が解放された開断面のコンクリート層を形成する吹付工程Ｓ４と、コンクリート層の表面を均す均し工程Ｓ５とを備えている。載置工程Ｓ２では、主筋が底板の板面と平行になるように鉄筋かごを載置する。また、仕切材は、底板側が開口するように配設する。【選択図】図２
