PURPOSE: To avoid densely-arranged shearing-reinforcing bars and remarkably increase a charging degree of concrete, by arranging a set of shearing- reinforcing bars for columns and beams in a reinforcing concrete structure so as to surround the whole main steel rods along the periphery of the section and by welding or bundling the superimposed parts.
CONSTITUTION: Tie-hoops 3 are arranged to form nearly a square so as to surround whole main reinforcing bars 1, 2 along the periphery of the column section and both ends thereof are welded together. And tie-hoops 4 are arranged to form a longitudinally long rectangle so as to surround the upper and lower main reinforcing bars 1, 2. All of the tie-hoops 3 are united at the ends thereof. One of the tie-hoops 4 or 5 are arranged inside the tie-hoop 3 in the almost the same plane as that of the tie-hoop 3. The other one thereof are arranged to be in the condition superimposed in double at the upper side or lower side. In this time, these tie-hoops 3, 4, 5 are welded or bundled as a unit in the superimposed parts A and the crossing parts B to make a unit in order to arrange at once.
