BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforced structure, and more particularly, to a reinforced concrete structure having a beam-column joint.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing a conventional reinforced concrete structure of a beam-column joint. FIG.

Referring to FIG. 1, in general, in the reinforced concrete structure, the order of the reinforcement of the joining portion between the external edge beam and the column is as follows.

The column main rope 1 is laid out and the joining pillar hoop 2 is bundled with the bundle at a position immediately below the planned position in the y direction. The structural effect of the conventional closed-joint column hoop 2 is such that the concrete inside the column is surrounded by the constraining effect of the concrete.

The uppermost corner of the x-directional beam The two strakes (3) are arranged, and the stirrup (4) of the x-directional beam is installed.

(5) of the x-directional beam and the two strands of the uppermost corner cast iron rods (6) of the y-directional beam.

the stirrup 7 of the y-directional beam is installed, and the lowermost casting steel rope 8 of the y-directional beam is placed.

FIG. 1 shows a case where the main beam is a first stage, but the following problems arise when the second stage is rearranged.

In the case of the upper-lower-end cast iron rope of the x-direction beam, it is impossible to arrange the cast iron rope hook (16db) because of the joining column hoop (2). Likewise, even in the case of the upper lower-end cast iron rope of the y-direction beam, it is impossible to arrange the cast iron root hook (16db) because of the joining column hoop (2).

That is, in this conventional reinforced concrete structure, the reinforcing of the reinforcing bars at the joining portions between the outer corner beams and the columns is very difficult due to the interference between the reinforcing bars and the joining column hoops (2).

That is, there is a problem in that the joining portion of the outer edge beam and the column has a reinforcing root intersecting in three directions (z column, x direction beam, y direction beam), and thus the joining of the joining column hoop (2) is difficult.

Alternative use is possible.

Second, it is possible to improve the fixation performance and the strength development of the reinforcing bar by combining the enlarged head serving as the fixing plate at the end of the reinforcing bar.

Third, the reinforcement bars are open in one direction, but the concrete of the beams located at the ends of the reinforcement bars prevents the reinforcing bars from spreading, and the enlarged heads screwed to the ends of the reinforcing bars prevent the reinforcing bars from being pulled, The restraining effect of the concrete inside the column can be exerted.

Fourth, when the beam-column connection is T-shaped in the plane, the reinforcing bars are joined in plural in one direction toward the inner beam from the outside, and even if only one reinforcing bar is used on the plane, the same performance as the conventional closed- have.

Fifth, when the beam-column connection is L-shaped in plane, the reinforcement rods can be orthogonally coupled in a plurality of directions from the outside toward the both side beams, and when the pair is tightly bonded to each other, .

Sixth, when the coupling member is a threaded coupler in both directions and the pair of reinforcing bars are provided and screwed together, the reinforcing rods and the coupling member can form a closed type hoop.

Seventh, due to the excellent transverse strength effect, the strength and stiffness of the joint increase, and the safety of the structure can be improved by improving the resistance against earthquake load.
