1. A reinforced structure for a column and beam frame comprising:
a reinforcing frame made of steel disposed in a structure plane of a frame of, a column and a beam of reinforced concrete structure,
the reinforcing frame being joined to an inner circumferential surface of the frame,
the reinforcing frame having an elevational shape surrounding the frame along the inner circumferential surface of the frame,
the reinforcing frame having a cross-sectional shape with a flange on a side of the frame; and
a web forming a surface perpendicular to the flange, the flange directly or indirectly overlapping the inner circumferential surface of the frame, wherein
the reinforcing frame includes:
a column portion along the column;
a beam portion along the beam; and
a connecting portion joined to the column portion and the beam portion, the connecting portion connecting the column portion to the beam portion, and
the connecting portion has a first flange part, from among parts of the flange, close to the column portion and a second flange part, from among the parts of the flange, close to the beam portion, shaped along the inner circumferential surface of the frame,
the first flange part disposed along the inner circumferential surface corresponding to the column, the second flange part disposed along the inner circumferential surface corresponding to the beam,
the first flange part, the second flange part, and a web part, from among parts of the web, corresponding to the connecting portion, are continuous in a circumferential direction of the reinforcing frame to a third flange part, from among the parts of the flange, corresponding to the column portion and a web part, from among the parts of the web, corresponding to the column portion, and to a fourth flange part, from among parts of the flange, corresponding to the beam portion and a web part, from among the parts of the web, corresponding to the beam portion, and
the first and second flange parts of the connecting portion form a corner part of the flange facing a corner of the frame, to form a void between the corner part and the corner of the frame.
