Field of the Invention The present invention relates to a joint structure in a steel pipe column and a method of constructing the same, and more particularly, to a joint structure between a steel pipe column and a steel beam, a butt joint structure between steel pipe columns,
The present invention relates to a rational technique for joining a steel pipe column and a column base member.

あった。2. Description of the Related Art Conventionally, as a method of joining a steel beam such as an H-shaped steel beam to a steel tube column, a horizontal diaphragm is interposed at a beam joint of the steel tube column, and a steel beam is welded to the horizontal diaphragm. It is a target. However, this method has problems that many cutting / welding steps are required, which is troublesome, and that it depends on the skill of the operator and that it is difficult to ensure accuracy.

差し入れるための開口部を設けなければならなかった。[0003] To date, as a column joining method that does not require a welding operation, there has been proposed a method in which a reinforcing member is provided inside a beam joining portion of a steel pipe column and a steel beam is bolted using the reinforcing member. (Japanese Unexamined Patent Publication No. 5-263468,
11-324226, etc.). However, in this method, it takes time and effort to insert the reinforcing member into the steel pipe column and securely fix the reinforcing member to the beam joint, and it is still difficult to ensure accuracy. When bolting a beam to this reinforcing member, an expensive one-side bolt must be used and a normal high-strength bolt must be used in places that are not accessible inside the steel pipe column. In such a case, an opening for inserting a hand into the steel pipe column had to be provided at the expense of the strength of the steel pipe column.
