In the above-mentioned conventional beam-column joint structure, the construction is complicated and time-consuming.
Since on-site welding is performed, the number of technicians required for construction increases, the quality may vary, and the work is easily affected by the weather, which has a significant effect on the construction period. Further, for a portion where it is difficult to arrange closed stirrups as in the above-mentioned conventional beam-column joint due to the accommodation of the beam-column joint, it is necessary to adopt another reinforcing method.

As a technique for solving this problem, instead of the above-mentioned closed stirrups, a straight bar bent into a substantially U-shape is provided with both ends directed toward the inside of the column and the main bars of the column at the bent portions. There is known a technique in which a main bar is restrained by arranging the main bar horizontally so as to cover from the outside of the column. However, according to this conventional technique, the reinforcing bars arranged around the columns are not continuous in the horizontal direction as in the closed stirrups, and the effect of shear reinforcement of the concrete in the beam-column joint is not sufficient. I can't get it. Since the beam-column joint is the part that receives only shearing force, it is necessary to surely reinforce the concrete in the beam-column joint.

According to the structure of the beam-column joint according to the first aspect of the present invention, no band is provided in the joint.
In the vertical plane in the joint, the concrete in the joint is sheared and reinforced by the shear reinforcing bars arranged in a state of crossing substantially in an X-shape. The shear strength can be increased. As described above, since the shear strength can be secured without the stirrup, a hole for inserting the stirrup is made in the beam steel web in the joint portion, and the plurality of divided stirrups are arranged through this hole. , And complicated work such as integrating these by field welding and finishing it into a loop-shaped strip,
In particular, the on-site welding work that is easily affected by the weather can be omitted. Further, the structure of the present column-beam joint can be applied to a portion where it is difficult to arrange the stirrups because of the fitting of the column-beam joint. Furthermore, since the structure of the beam-column joint is simple, the construction accuracy of the joint can be improved.

According to the structure of the beam-to-column joint according to the first aspect of the present invention, no streak is provided in the joint, but the beam crosses substantially in an X-shape in a vertical plane in the joint. The shear reinforcing bars arranged in a state where the concrete in the joint portion is reinforced by shearing can increase the shear strength of the concrete even without the stirrup in the joint portion. As described above, since the shear strength can be secured without the stirrup, a hole for inserting the stirrup is made in the beam steel web in the joint portion, and the plurality of divided stirrups are arranged through this hole. , And complicated work such as integrating these by field welding and finishing it into a loop-shaped strip,
In particular, the on-site welding work that is easily affected by the weather can be omitted. Further, the structure of the present column-beam joint can be applied to a portion where it is difficult to arrange the stirrups because of the fitting of the column-beam joint. Furthermore, since the structure of the beam-column joint is simple, the construction accuracy of the joint can be improved.

According to the structure of the beam-to-column joint according to the second aspect, the same effect as in the first aspect is obtained, and the use of the reinforcing bar allows the inside of the joint to be provided without providing the band. Of the concrete around the main rebar and buckling of the main rebar can be prevented. Therefore, it is not necessary to provide a strip that complicates the work when the reinforcing bars are arranged in the joint, and the workability of the joint is improved.

According to the structure of the beam-column joint according to the third aspect, the same effect as in the first or second aspect is obtained, and the through-hole provided in the beam steel web or the steel frame panel in the joint is provided. Since the reinforcement can be easily arranged by inserting the shear reinforcing bars, the workability of the joint is improved.
