REINFORCEMENT ASSEMBLY AND SHEAR REINFORCING BARS USED FOR REINFORCED CONCRETE STRUCTURE

WIPO Patent Application WO/2013/150668

A1

[Problem] To provide a reinforced concrete structure in which sufficient concrete cover thickness can be obtained. [Solution] A column, representing a reinforced concrete structure, is provided with concrete (22), and a reinforcement assembly embedded in the concrete (22). The reinforcement assembly has: a plurality of main reinforcements (24) extending in a straight line so as to be parallel to each other; and shear reinforcements (10A) arranged at intervals along the longitudinal direction of the main reinforcements (24) so as to enclose the main reinforcements (24). The shear reinforcements (10A) are arranged at the outermost position of the reinforcement assembly. The distance between the outer periphery of the shear reinforcements (10A) and the concrete surface (22a) represents the concrete cover thickness (T). Each of the shear reinforcements (10A) is made from a reinforcement bar having a flat cross-section, arranged so that the direction of the short axis X of the cross-section is orthogonal to the concrete surface (22a), and bent so that a pair of surfaces (11a, 11a) that face each other in the direction of the short axis (X) are positioned on the inside and the outside.
