(Prior art and its problems) When joining a steel beam to a steel column, as shown in FIGS. 12 and 13, a pipe material 3 or a parallel or tapered pipe is Using a member (joint parts) with diaphragms 2, 2 welded to both ends of 3', a beam 5... brought out from the side is butt welded,
From the top and bottom, the ends of the column pillar material 1 are butt welded to the diaphragms 2, 2 to be assembled. The joint part used for such a joint part is made by processing the tip of a square pipe 3 with a re-bevel, and by bending a flat bar and dividing it into two or four parts into a backing metal 4 (see Fig. 7). 8th
As shown in the figure and FIG. 9, while adjusting the dimensions of the diaphragm 2 inside the end of the square pipe,
Temporarily weld the diaphragm 2 and place it in contact with the diaphragm 2.
As shown in Figure 0, it is manufactured by welding multiple layers in a downward position (see Figure 11), but since the bending of the backing metal is done with a simple tool or press, the precision of the R part of the square pipe is limited. Because of the non-uniformity, during installation, the backing metal of the R portion is usually heated with gas to ensure close contact. This causes welding defects. Specifically, unmelted areas on the square pipe root surface, burn-through, and insufficient penetration on the diaphragm side occur.

(Means for Solving the Problems) The present invention is capable of replacing the role played by a backing metal by a combination of flux backing and groove shape when joining steel frame joints by welding. It was completed with a focus on what could be done, and its gist is: ``When welding a diaphragm to both ends of a pipe material, the welding groove between the pipe material and the diaphragm is a J groove, and the inside of the pipe material is filled. This is a welding method for steel frame joints, in which the first layer is welded in a horizontal position by backing with the flux applied.

In other words, the roles of the backing metal include assembling the square pipe and diaphragm, adjusting the height dimension, ensuring the groove shape, and preventing leakage of welded metal. By applying a J-bevel, the square pipe can be assembled directly to the diaphragm with a metal touch (dontsuke), ensuring a bevel while completing the assembly of the square pipe and diaphragm without having to adjust the height. Since leakage of welded metal is prevented by backing by enclosing flux in the square pipe, no backing metal is required.

(Operations and Effects of the Invention) As is clear from the above description, according to the present invention, a pipe material is used as a joint member, and a diaphragm that joins the end of a column is welded to both ends of the pipe material to form a steel joint part. When forming, the welding groove of the pipe material with the diaphragm is a J-bevel, and the pipe material is buckled with flux filled inside the pipe material, so there is no need for a backing metal that requires bending, dimensional adjustment, installation, etc. Work efficiency is improved because the welding work at the joint part becomes easier.
In addition, welding defects due to poor welding do not occur, so
This has the advantage of significantly improving the yield of joint parts.
