Construction is turned with ball pivot of turning to bridge to satisfy the vertical bearing capacity of bridge construction overall process, the ball pivot upper portion bridge structures's that realizes turning free rotation. Including a pair of the last ball pivot that has a concave spherical surface under the looks adaptation, ball pivot down, the ball pivot should be gone up, an integral antifriction plate was provided with between the ball pivot down, shear force round pin passes ball pivot, antifriction plate and lower ball pivot along the rotation axis of the ball pivot of turning. The said annular all edge equipartition of going up the ball pivot has the mounting hole that supplies pre-buried rod iron to pass, and lower ball pivot passes through bolt assembly and installs on pre-buried support.
