SLIDING CONCRETE PLACING DEVICE, AND CONSTRUCTION OF CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a sliding concrete placing device capable of preventing the deterioration of quality of the concrete due to the exposure with the dry condition in early time by preventing the generation of friction between a surface of the concrete and a sliding form. SOLUTION: A sliding concrete placing device includes a sliding form 10 assembled along the peripheral part of a structure to be constructed and to be placed therein the concrete C and a sliding form moving means (climbing jack 30, a reaction force rod 31) for moving the sliding form in a constant direction along the peripheral part. The device is also provided with a concrete surface protecting member (a water permeable sheet S) interposed between the sliding form and the surface of the placed concrete, and a concrete surface protecting member feeding means (a sheet feeding mechanism 41, a sheet winding mechanism 42) for feeding the concrete surface protecting member from a traveling direction side of the sliding form to the opposite side.
