Further, this end plate 2 has a plurality of holes 4 for fixing piano wire steel rods 3 adjacent thereto, which are used to fix the end plate 2 in a mold when manufacturing concrete piles 1 in a factory. A screw hole 5 is bored. Reference numeral 6 denotes a reinforcing bar, and the lower end thereof has a protruding hole 7 that can be screwed into the screw hole 5, and a spanner that can be used by abutting a spanner on the upper part of the part where the screw 7 is provided. A locking recess 8 is provided. Further, numeral 9 is a bolt having a screw 7 at its lower part which can be screwed into the screw hole 5.

By embedding reinforced reinforcing bars into the footings and connecting the footings and concrete piles, the two can be connected extremely strongly and reliably, making them resistant to earthquakes, etc., and further improving the surroundings of the concrete piles. Even if the adhesion between the face and the concrete of the footing is broken, shearing force can be reliably transmitted, and compared to the case of embedding the reinforcing bar cage in the antiseptic cavity described above, the same reinforcing bar will resist bending. It is extremely strong and advantageous, and it can be fixed to concrete piles by driving reinforcing bars or bolts, so the work accuracy is good and reliable, and the overall work is simple and has good workability. ing.
