部材４，５との間で切り欠きが出来て応力集中が発生
し、強度を弱める結果となる。Most of the conventional structural steel beam-column joints are manufactured by using the dice shown in FIG. 1. In FIG. 1, the diaphragm 1, the square steel pipe 2, the backing plate 1 are formed.
There are many members such as 0 and end tabs, and the weld 6 makes a round around the rectangular steel pipe 2 and the welding amount is large. Therefore, there is a problem that the cost for manufacturing the parts is high, and the diaphragm bends after the dice are manufactured as shown in FIG. 34, which causes a so-called umbrella bending phenomenon, and a difference is likely to occur between the diaphragm and the beam flange. Further, it takes time and cost to attach the backing plate 10 to the inner circumference of the end of the rectangular steel pipe 2 and perform the tack welding 8. Moreover, since the welding 6 of the rectangular steel pipe 2 and the diaphragm 1 is performed over the entire circumference, the welding amount is large, so that not only the welding residual stress becomes large, but also when the backing plate 10 is used, the welding is performed between the members 4 and 5. Notches are created and stress concentration occurs, resulting in weakening the strength.

にリブとして変更する場合も同様の問題が存在する。Further, as shown in FIG. 7, the dice 20 integrally formed with the conventional cast steel has a relatively simple structure as compared with the conventional welded structure shown in FIG. 1, and has an advantage that the structural yield strength is improved. is there. However, the structure shown in FIG. 7 requires two reinforcing plates 22 above and below, a total of four reinforcing plates 22 in total, and the space 22A formed by the reinforcing plates 22 expands inside, and It requires 3 spaces. Such a space 22A requires a complicated core at the time of casting, which increases the man-hours for manufacturing the core and the man-hours for casting, which causes a cost increase. Further, in FIG. 7, when the beam, that is, the height of the beam joined to the dice is lower than that of the dice, the horizontal position of the internal reinforcing plate and the horizontal position of the beam flange are set to match. However, it is necessary to manufacture the horizontal position of the internal reinforcing plate in consideration of the height of the beam, and when there are various beam heights, it is difficult to manufacture and the beam height is limited. The same problem exists when the internal reinforcing plate is omitted or is changed to a rib on one corner.

影響部よりも脆化しやすいと言う問題がある。Further, since the weld heat-affected zone is generally prone to embrittlement, conventionally, when the two welded portions are close to each other, the heat-affected zones of both welded portions do not overlap each other so that the embrittlement is further promoted. It is customary to keep welds away from each other so that the heat affected zones do not overlap. In particular, it is a problem that a portion where the welding heat effects of both welded portions overlap is exposed to the outer surface. Japanese Patent Application No. 10-312771 does not describe the proximity of the welded portion, but as shown in FIG. 18, the welded portion 24 between the pillar 5 and the integrated dice 23 is connected to the beam 4 and the integrated dice 2.
When a common welding heat affected zone 35, which is close to the weld zone 25 with 3 and sandwiched between the two weld zones, is formed on the outer surface, the heat affected zone is more apt to be embrittled than a single heat affected zone.

At the construction site, columns with panel zones are erected upright and then short beams are connected by bolts with long beams. In this conventional method, although the pillar with a beam is short in length of about 1 meter, it is inefficient to transport from the factory to the site because the beam extends in 4 directions orthogonal to the pillar, and there are many beams at the construction site. There is a problem in that the joining using the bolts of (2) requires more man-hours and costs than welding.

It was judged that it is better to integrate the dice parts in the dice composed of, and further, in order to solve the problem of the integrated dice shown in FIG. 7, as a result of various studies, the reinforcing plate was omitted and the solid dice was omitted. Further, it was found that the problem of overlapping of the heat-affected zones of welding shown in FIG. 18 can be achieved by integrating the column-beam welds. Also, when making the dice solid, it is better to make it solid with cast steel, as it is meaningless to make a cavity in the axial center as the size of the dice becomes smaller, since only thick-walled parts can be made with cast steel. , And found that thick rolled materials and forged steel materials can also be manufactured.

Therefore, it is possible to reduce the weight of the dice by providing a cylindrical space along the central axis, but if the diameter of the cylinder is made too large, the flange in-plane strength of the solid part will be stronger than that of the column. It turned out to be weaker than. Therefore, if the solid partial cross-section minimum width of the upper end surface or the lower end surface of the rectangular parallelepiped is 25% or more of the beam flange width, the weight can be effectively reduced without impairing the strength of the solid portion. found. However, when the reinforcing plate shown in FIG. 7 is used, the ease of manufacturing, the cost, and the degree of freedom in the position of the beam flange are not provided as described above, which causes inconvenience when applied to a structure. In that respect, if it is a cylindrical space such as a cylinder, it can be easily manufactured by mechanical processing for rolled steel or thermal processing such as gas cutting, and it can be manufactured by using forged steel or forged steel die, and it is a complicated casting plan for casting It can be easily manufactured at low cost without using. The novelty of the present invention resides in that in addition to the novelty of the invention according to claim 1, a substantially uniform cylindrical space is provided in the vertical central axis of the rectangular parallelepiped in the vertical direction.

5% + 7 mm or less, in the case of column joining the deviation b, that is, 31A
Is preferably 25% of the column plate thickness + 7 mm or less. The deviation a,
When b is equal to or more than these values, the welded portion is integrated and the welded portion becomes too large, the weld residual stress becomes large, and the amount of welding increases, which causes an increase in manufacturing cost. Therefore, the vertical total length 23 of the rectangular dice shown in FIG.
A is the height of the beam 3 joined to the rectangular parallelepiped 23, that is, 4A.
It is desirable that the length be less than or equal to 50% of the flange plate thickness plus 14 mm. Further, the outer dimensions of the upper and lower ends of the rectangular dice, that is, the side length 23B of the dice, is the column side length 5
