フープＢｂが入っている。"Problems to be Solved by the Prior Art and the Invention" A conventional steel reinforced concrete column consists of a steel frame A and a reinforced concrete B covering it, as shown in Figure 9.The steel frame A is mainly subject to shear force. Resisting cross-shaped web A
a, and a flange material Ab that resists axial force and bending moment.
The reinforced concrete B includes main reinforcements Ba that bear the axial force and bending moment, and hoops Bb that bear the shear force.

するため、加工工数が多く、Ｈ型に比してコストアンプ
の要因になっている。By the way, when designing this steel-framed reinforced concrete column, the strength of the steel frame and reinforced concrete parts is cumulatively designed, but in this case, the steel frame requires a large number of machining steps because many pieces are consolidated, and compared to the H type. This is a factor in increasing costs.

。Therefore, the present invention aims to simplify the steel frame portion of a conventional steel reinforced concrete column, reduce the amount of iron, reduce the number of processing steps, and reduce costs.

フープ乃至主筋に係合させたことを特徴とする。"Means for Solving the Problems" One aspect of the present invention is a steel-framed reinforced concrete column consisting of a steel frame and reinforced concrete covering the column, in which the steel frame is relatively simple, such as a cross-shape, an L-shape, a T-shape, etc. It is characterized in that a large number of auxiliary reinforcements are attached to the steel frame and these auxiliary reinforcements are engaged with the hoop or the main reinforcement.

タッドジベルをフープに対応させたことを特徴とする。Another method is to use relatively simple steel frames such as cross-shaped, L-shaped, and T-shaped steel frames in steel-framed reinforced concrete columns consisting of a steel frame and reinforced concrete covering the steel frame, and to install a large number of stud dowels on the steel frame. It is characterized by having these stud dowels correspond to hoops.

が不要となるのである。``Operation'' With the above structure, the bonding force between the steel frame and reinforced concrete is greatly increased, and the reinforced concrete can play a role equivalent to the flange material of the steel frame. In other words,
In reinforced concrete, the ability to resist axial force and bending moment can be increased, eliminating the need for steel flanges.
