Thailand carbon steel round flange end plate for spun pipe pile Magyarország

End plate for concrete piles:

The present invention discloses a pair of identical top and bottom end plates for joining two independent pipe piles, the top end plate being located at the bottom end of a first pipe pile, the bottom end plate being located at the top end of a second pipe pile, the two piles being joined by interlocking the top and bottom end plates together, the end plates comprising: a protruding section and a recessed section having local hot-forged grooves for accommodating the round head and base of a prestressed steel bar tendon; a 45-degree turned square opening leading to a tapered square hole, the tapered square hole being formed by the tapered dovetail grooves of the top protruding section and the bottom recessed section and the top recessed section and the bottom protruding section; a tapered square pin corresponding to the tapered square hole, the tapered square pin being able to be squeezed into the tapered square hole through the square opening, thereby interlocking the end plates; an outer edge located on the lower side of the protruding portion, having a rectangular deep groove that crosses the outer circumference of the end plate, which can be embedded with the lip edge of a circular steel skirt plate; and a beveled edge on the edge of the protruding section above the tapered square pin, for preventing the dovetail groove from being compressed during impact piling.
