According to this configuration, by arranging the connecting members at a plurality of positions in the vertical direction according to the positions at which the bars are connected to the auxiliary column members, the connecting members are arranged at a plurality of positions in the vertical direction. It is possible to reduce the weight of the member, and consequently to reduce the weight of the strut connection structure.

In addition, the connecting portion is arranged on both sides in the width direction with respect to the end portion of the first bar and the end portion of the second bar, and the end portion of the first bar and the second bar It is preferable that the end portions are arranged side by side in the width direction in a region sandwiched between the connecting portions.

According to this configuration, the connecting portion for fastening and fixing the first bar and the connecting portion for fastening and fixing the second bar can be easily used together, and the number of connecting portions in the connecting member can be reduced by sharing the connecting portion. be able to.

Preferably, the auxiliary column member and the pair of plate-shaped portions are fastened and fixed to the pair of plate-shaped portions from both sides in the width direction by fastening members at a plurality of locations in the vertical direction. be.

According to this configuration, by fastening and fixing the auxiliary column member and the pair of plate-shaped portions, the time required for assembling the column connection structure can be easily shortened and the cost can be reduced as compared with the case where these are fixed by welding. can be kept low.

Moreover, it is preferable that the fastening members are arranged at regular intervals in the vertical direction.

According to this configuration, since the auxiliary column member and the column are fastened and fixed at a constant interval, variations in the strength of the column depending on the position along the vertical direction can be suppressed.

Moreover, it is preferable that the connecting member is arranged in a region where the fastening member exists in the vertical direction.

According to this configuration, since the connecting member can be arranged at a position close to the fastening member in the vertical direction, it is possible to make it difficult for the strut to become bent between the connecting member and the fastening member. .

Moreover, it is preferable that the auxiliary column member is a tubular member having a polygonal cross section.

According to this configuration, since the plate-like portion of the support and the auxiliary column member can be brought into surface contact with each other, deformation of the plate-like portion of the support can be easily suppressed by the auxiliary column member.

Further, the auxiliary column member is installed only in a reinforcing region that is a partial region of the entire vertical direction of the column, and connects the pair of columns in a region of the column other than the reinforcing region. Preferably, a plurality of connecting rods are provided and the ends of said connecting rods are directly connected to said struts.

According to this configuration, for example, by setting the auxiliary column member in the area that needs to be reinforced, for example, by setting the area where the load is likely to be concentrated, such as the area at the bottom of the column, as the reinforcement area, it is easy to suppress the deformation of the column. Become. In addition, in areas other than the reinforcement area, the connecting rods are directly connected to the pillars without installing the auxiliary pillar members. The simplification of the structural configuration can be achieved.

The technology according to the present disclosure can be used in a column connection structure including a pair of columns installed along the vertical direction, a pair of auxiliary column members, and a connection truss that connects the pair of auxiliary column members. can.
