Abstract
A T-headed stirrup for anchoring reinforcing bars in concrete, to restrain lateral buckling of the reinforcing bars under severe forces. The stirrup, comprising a shaft with a T-shaped crosspiece at each end, is typically inserted between pairs of reinforcing bars. The crosspiece contacts the reinforcing bar and is shaped to restrain lateral movement of the reinforcing bar.
Claims10
A stirrup for restricting movement of a reinforcing member in concrete, comprising a shaft having a rigid crosspiece at both ends, with the crosspiece length being greater than the shaft width, each crosspiece being perpendicular to the shaft and parallel one to the other, and each crosspiece having a proximal and distal surface relative to the end of the shaft, said proximal surface having at least one reentrant defined by said rigid crosspiece.
A concrete structure comprising at least two parallel reinforcing bars, said reinforcing bars being restrained from vertical and lateral movement by a stirrup comprising a shaft having a rigid crosspiece at both ends, with the crosspiece length being greater than the shaft width, each crosspiece being perpendicular to the shaft and parallel one to the other, and each crosspiece having a proximal and distal surface relative to the end of the shaft, said proximal surface having at least one reentrant defined by said rigid crosspiece.
