題がある。As a method of joining pillars having a closed cross section such as square steel pipes and circular steel pipes with bolts, flanges are provided on the outer periphery of the column head of the lower column member and the column base of the upper column member to be joined, and this outer peripheral flange is used. The method of joining with a bolt is adopted. However, such a joining method is not preferable in terms of aesthetics in a pillar in which the joint portion of the pillar can be seen from the outside. It is joined by. However, the welding method has a problem that when welding on site, it is necessary to bring welding equipment to the site, which requires a lot of man-hours, and when carrying out welding at a factory in advance, the transportation efficiency becomes poor. .

ブに嵌合固定されるピンテール4dからなっている。From such a point of view, the joining by bolts has been often employed also in the joining of columns and beams having a closed cross section. One method (a method) of bolting columns and beams having such a closed cross-section is described in Japanese Patent Laid-Open No. 6-093661. This is to join an H-shaped steel beam with a split tee to a square steel tubular column.
As shown in FIG. 2, the T-shaped split tee 2 is placed outside the square steel pipe 1, the joint metal 3 is placed inside the square steel pipe 1, the pipe wall of the square steel pipe 1 is sandwiched, and a special bolt is bolted from the inside of the square steel pipe 1. It is fastened through the hole. The special bolt 4 includes a flat round head 4a, a shank 4b, and a male screw portion 4
c, a pin groove 4e formed subsequent to the male screw portion 4c and a pin tail 4d formed in the tip and fitted and fixed to the inner sleeve of the torque wrench so that the bolt does not rotate when the nut is rotated and fastened. ing.

いる。The temporary fixing metal fitting 7 has a cylindrical shape with one end closed and the other end open, and a plurality of slits reaching the opening end are formed in the cylindrical portion, and a rib formed by bending the opening end to the outside. Are formed. The outer diameter of the rib portion can be made smaller by grasping it with pliers or the like, and when released from the pliers, the original diameter is restored by the spring force. As shown in FIG. 8, one end of the tie string 8 is fixed to the temporary fixing metal 7, and the tip of the pin tail of the special bolt 4 is connected to the other end.

In order to attach it to the inner wall of the square steel pipe 1 and the split tee 2 on the outer wall of the square steel pipe, the metal fittings 3 in which the temporary fixing metal fittings 7 with the special bolts connected by the string as described above are mounted in the bolt holes in advance. Align the bolt holes and temporarily attach by welding. By hooking the pulling rod on the hook 7a of the temporary metal fitting 7 and pulling it out, the special bolt 4 is inserted into the bolt hole (joint metal, square steel pipe wall and bolt hole of split tee) and fastened with a nut. Is the thing.

As shown in FIG. 7, this method is as follows: "First, insert the special bolt 4 into the bolt hole from the inside of the rectangular steel pipe 1. Next, the filler made of foamed resin having the long groove 9a into which the head of the special bolt 4 is inserted. 9 is inserted into the rectangular steel pipe 1 to support the special bolt so that the special bolt does not fall into the rectangular steel pipe 1. The split tee 2 is fastened to the rectangular steel pipe 1 via the special bolt 4 and attached to the split tee 2. Then, the beam 6 is bolted. ”
