PROBLEM TO BE SOLVED: To easily join a steel pipe column and a beam and enhance the reliability. SOLUTION: Lower and upper parts of a cylindrical body 4 are closed by diaphragms 5, 6. The external shape of the cylindrical body 4 has the same diameter over a whole length. A Steel pipe columns 1, 1 are fixedly welded to both upper and lower ends of a connection core integrally molded with cast steel in the whole body. A beam 2 is fixedly welded to the side face of the cylindrical body 4 of the connection core 3. By casting the core in this way, the assembling error of the core body or welding deflection is eliminated. Quality and strength can be stabilized. Even when an inner diaphragm is required to be put in the connection core 3, integral molding can be formed by casting in a necessary part. The stress of a beam having a different height is rationally transmitted to the inner diaphragm. COPYRIGHT: (C)2004,JPO
