BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing steel reinforcing structure for reinforcing concrete, a reinforcing concrete structure including the same, and a reinforcing concrete reinforcing method using the same.

The reinforced concrete structure is a structure made of concrete to resist compressive stress and reinforcing bar to resist tensile stress. It is resistant to vibration and shock, has low vibration and noise due to vehicle load, and has low cost per unit volume .

In addition, even if the concrete member is heated due to the fire resistance, the predetermined covering thickness is ensured by the heat insulating action of the concrete. to be.

However, when a load acts on a reinforced concrete structure, a shear force is generated, and when the shear failure occurs, the cracks suddenly occur due to a 45 ° inclined sign crack.

As such, the reinforced concrete structure itself has a problem in that it can not receive moment or tensile stress alone due to its insufficient tensile strength, and it is a structure in which reinforcing bars are arranged at a position where tensile stress is generated.

On the other hand, since the concrete is basically a compression-resistant material, the reinforced concrete member can effectively resist compression. However, if the concrete and the tensile steel are not transversely restrained by the transverse reinforcement placed in the direction perpendicular to the member, the brittle concrete failure occurs due to the compressive force, and the ductility and seismic performance of the reinforced concrete member are deteriorated.

In order to reinforce the ductility and seismic performance of these reinforced concrete structures, U-stirrup, welded wire mesh, lattice reinforcement, and steel bar reinforcement with 90 ° or 130 ° end claws are used as transverse steel reinforcement. U- And bar reinforcing bars are commonly used.

1 is a schematic view schematically showing a state in which U-stirrup is used as a transverse steel reinforcing bar and connected to steel bars.

Referring to FIG. 1, the main reinforcing bars 1 extending in the vertical direction are arranged at predetermined intervals, and the main reinforcing bars 1 are arranged in two rows.

At this time, in order to structurally reinforce the cast iron rods 1 from the lateral external force, a plurality of U-stirrups 2 are used to connect the cast iron rods 1 together.

However, when a plurality of such U-stirrups 2 are used, there is an inconvenience that the U-stirrups 2 must be sandwiched separately from the upper or lower ends of the main steel bars 1. Similarly, There is an inconvenience.

Accordingly, there is a high demand for a technique capable of increasing the structural stability of a reinforced concrete structure with respect to lateral external forces and increasing the workability.
