As shown in FIGS. 2A and 2B, the cylindrical member 21 is formed of a steel pipe having a circular cross section.

  In the present embodiment, as shown in FIG. 1, the reinforcing member 2 (wall body) is configured by arbitrarily disposing cylindrical members 21 having different diameters.

  As shown in FIGS. 2A and 2B, the cylindrical members 21 are detachably disposed by being connected to each other via a connecting bolt 23. Further, the cylindrical member 21 at the end in contact with the steel frame 20 is also detachably connected to the steel frame 20 via a connection bolt 23.

  As shown in FIG. 1, among the plurality of cylindrical members 21, 21,... Constituting the reinforcing body 2, some cylindrical members 21, 21,. It is shielded by.

  The plate-like member 22 is a circular steel plate formed according to the opening of the cylindrical member 21, and as shown in FIG. 2B, the depth direction of the cylindrical member 21 (the thickness direction of the reinforcing body 2). ) By welding at the intermediate portion. The plate member 22 may be fixed to the end of the cylindrical member 21 in the depth direction.

The arrangement of the cylindrical member 21a in which the plate-like member 22 is arranged in the opening and the cylindrical member 21b in which the plate-like member 22 is not arranged is determined in consideration of energy transmission and design of the reinforcing body 2. .
In the present embodiment, it is assumed that the cylindrical member 21a having the plate-like member 22 is continuously disposed obliquely, and the cylindrical member 21b is disposed in the remaining space. In the present embodiment, the cylindrical member 21a is arranged in a state in which two X-characters are arranged side by side in the plane of the column beam frame 1.

  Further, the cylindrical member 21a on which the plate-like member 22 is disposed is configured to disperse the acting stress by contacting the other cylindrical member 21 or the steel frame 20 at least at three points. Yes.

In the present embodiment, the connection between the cylindrical members 21 and the connection between the cylindrical member 21 and the steel frame 20 are performed by the connection bolts 23. For example, the connection may be performed by welding. The fixing method is not limited. In addition, when the cylindrical member 21 is disposed in contact with the other cylindrical member 21 or the steel frame 20, force can be transmitted, and if there is no possibility of coming out, the connecting bolt is not necessarily used. It is not necessary to be fixed by 23 or welding.
In the present embodiment, the plate-like member 22 is integrally fixed to the opening of the cylindrical member 21 by welding, but the plate-like member 22 may be detachably fixed via a bolt or the like.

  The reinforcement structure A is constructed by stacking the cylindrical members 21 after forming the steel frame 20 by combining the shape steel along the shape of the column beam frame 1. The cylindrical member 21 is performed by first positioning the cylindrical member 21a having the plate-like member 22 and placing another cylindrical member 21 in the gap formed thereby. Here, the construction method of the reinforcing structure A is not limited, and may be appropriately performed. For example, the steel frame 20 may be formed by carrying in a rectangular shape in advance and arranging the steel frame 20 on the column beam frame 1 or by assembling steel materials on site.
