The present invention relates to a reinforcement arrangement structure to effectively reinforce the shear force of a coupling beam for special reinforced concrete, which is designed to have a span-to-depth ratio (ln/h) equal to or smaller than four between columns or walls and, more specifically, a reinforcement arrangement structure having construction ability improved by using cross reinforcements and head bars to distribute the shear force of a coupling beam. The reinforcement arrangement structure according to the present invention comprises at least two pieces of upper main reinforcements having both ends mounted on a column or a wall and horizontally placed in an axial direction; at least two pieces of lower main reinforcements having both ends mounted on the column or the wall and horizontally placed in parallel to the upper main reinforcements; hoop reinforcements tied around the upper and lower main reinforcements; a pair of cross reinforcements having both ends mounted on the column or the wall and placed in the diagonal direction to cross each other inside the hoop reinforcements; and multiple head bars which have heads having cross sections larger than those of rod-shaped bodies and mounted on the ends of the bodies and have the bodies placed toward spaces surrounded by the hoop reinforcements, and which are fixed and mounted on the upper and lower main reinforcements or on the hoop reinforcements. |
