To provide a reinforcing metal fitting for reinforced concrete beam with hole capable of making its outer diameter smaller so as to lower the height of a beam possible, capable of adjusting the position of stirrups so that the relative position of the stirrups and a sleeve is optimum, also capable of exhibiting sufficient reinforcing effect by integrally cooperating with the stirrups.

The reinforcing metal fitting consists of a frame-shaped body 3a formed by bending a bar steel for reinforced concrete, an upper pressing means 2 which projects levers 2b, 2c and 2d downward from the almost central part of a bar body 2a so as to be able to abut on the upper face of the sleeve B and which can be attached to the upward part of the frame body 3a, and a lower supporting means 3b which projects a supporting lever 3c upward from the almost central part of the bar body 3a so as to support the under face of the sleeve B with the supporting lever 3c and which is locked to the downward part of the frame body 3a.
