MOLD FOR CAST-IN-PLACE STEEL CONCRETE PILE AND CONSTRUCTION METHOD OF EXTRA FILLING PART OF CAST-IN-PLACE STEEL CONCRETE PILE

Japanese Patent JP2023034396

A

To provide a mold for a cast-in-place steel concrete pile and a construction method of an extra filling part of the cast-in-place steel concrete pile allowing a concrete amount to be installed to construct the extra filling part to be reduced while securing height of concrete required for the extra filling part, and allowing labor hours and cost to remove the extra filling part to be reduced, for the cast-in-place steel concrete pile.SOLUTION: A mold 1 is provided with an upper side mold part 2, a lower side mold part 3 coaxially placed below the upper side mold part 2 with a space therebetween, a support part 4 supporting them, and a reinforcement frame 6. Further, in addition to those structures, a cover part 5 is arranged to seal a gap between the upper side mold part 2 and the lower side mold part 3. Then, concrete C is filled in a drilled hole 30 to an upper end of the upper side mold part 2 in a state the mold 1 is placed and fixed on a steel pipe 22 from the lower side mold part 3 side.SELECTED DRAWING: Figure 1
