It is in the engaged state. The two connecting bodies 24 and 25 are arranged such that the upper bent portion 24c of the first connecting body 24 is in contact with the lower surface of the upper edge portion 23a of the both plate members 23 or positioned below the upper edge portion 23a. Is done.

次に、ビーム部材２２の連結用フランジ部２２ａを、第１連結体２４の第１側部折曲げ部２４ｂの外側に位置する板材２３に当接させた状態で、連結用ボルト４１を連結用フランジ部２２ａに設けられた挿通穴２２ｂ、板材２３に設けられた挿通穴（図示せず）および第１側部折曲げ部２４ｂに設けられた挿通穴２４ｆを介してフランジ付き六角ナット４２のねじ穴に螺合させて締め付ければ、ビーム部材２２を桁部材２１側に連結することができる。 Next, the connecting bolt 41 is used for connecting in a state where the connecting flange portion 22a of the beam member 22 is in contact with the plate member 23 located outside the first side bent portion 24b of the first connecting body 24. Screw of hexagon nut 42 with flange through insertion hole 22b provided in flange portion 22a, insertion hole (not shown) provided in plate member 23, and insertion hole 24f provided in first side bent portion 24b If it is screwed into the hole and tightened, the beam member 22 can be connected to the beam member 21 side.

勿論、この連結用ボルト４１の締め付け時においては、フランジ付き六角ナット４２の六角頭部は第２連結体２５の第２側部折曲げ部２５ｂの六角穴２５ｆに係合されているため、フランジ付き六角ナット４２の回り止めを行う必要がなく、したがって締め付け作業が容易となる。なお、第１連結体２４の第１側部折曲げ部２４ｂの下部は、板材２３に、直接、連結用ボルト４５および４６により連結される。勿論、第１側部折曲げ部２４ｂの下部には、ボルトの挿通穴２４ｈが形成されている。 Of course, when the connecting bolt 41 is tightened, the hexagonal head of the flanged hexagon nut 42 is engaged with the hexagonal hole 25f of the second side bent portion 25b of the second connecting body 25. There is no need to prevent the attached hexagon nut 42 from rotating, and therefore the tightening operation is facilitated. In addition, the lower part of the 1st side part bending part 24b of the 1st connection body 24 is connected with the board | plate material 23 with the volt | bolts 45 and 46 for connection directly. Of course, a bolt insertion hole 24h is formed in the lower portion of the first side bent portion 24b.

さらに、ビーム部材２２に柱部材３３を連結する場合、当該柱部材３３の下端に設けられた連結用フランジ部３３ａを、桁部材２１に取り付けられた第１連結体２４の上折曲げ部２４ｃに載置した後、端部フランジ部３３ａおよび上折曲げ部２４ｃに形成された挿通穴３３ｂ，２４ｇに連結用ボルト４３を挿通させ、そしてナット４４を介して両者を締め付ければよい。 Further, when the column member 33 is coupled to the beam member 22, the coupling flange portion 33 a provided at the lower end of the column member 33 is connected to the upper bent portion 24 c of the first coupling body 24 attached to the beam member 21. After mounting, the connecting bolt 43 may be inserted into the insertion holes 33b and 24g formed in the end flange portion 33a and the upper bent portion 24c, and both may be tightened via the nut 44.

上述したように、桁部材２１とビーム部材２２とを連結する際に、第１連結体２４の内側空間Ｓ内に第２連結体２５を配置し、しかもこのとき、両連結体２４，２５の側部折曲げ部２４ｂ，２５ｂ同士の隙間に、連結用ボルト４１が螺合されるフランジ付き六角ナット４２を、そのフランジ部４２ａが位置するようになし、この状態でビーム部材２２側の連結用フランジ部２２ａの挿通穴２２ｂ、両連結体２４，２５の側部折曲げ部２４ｂ，２５ｂに設けられた挿通穴２４ｆに、連結用ボルト４１を挿通させるとともに、第２連結体２５の側部折曲げ部２５ｂ側に保持されたフランジ付き六角ナット４２に螺合させて締め付けることにより両者の連結を行うようにしたので、従来のように、桁部材の端部に凹状部を形成して柱状部を当該凹状部に嵌入させて結合するようにしたものに比べて、その構造が簡単となり、したがって製造コストの低減化を図ることができる。 As described above, when connecting the beam member 21 and the beam member 22, the second connecting body 25 is disposed in the inner space S of the first connecting body 24, and at this time, both the connecting bodies 24, 25 are connected. A flanged hex nut 42 into which the connecting bolt 41 is screwed is inserted into the gap between the side bent parts 24b and 25b so that the flange part 42a is positioned. The coupling bolt 41 is inserted into the insertion hole 22b of the flange portion 22a and the insertion holes 24f provided in the side bent portions 24b and 25b of both the coupling bodies 24 and 25, and the side folding of the second coupling body 25 is performed. Since the two are connected by screwing and tightening the flanged hex nut 42 held on the bent portion 25b side, a concave portion is formed at the end of the girder member as in the prior art. The concave shape Compared to those adapted for coupling by fitting into, its structure is simple, therefore it is possible to reduce the manufacturing cost.

また、連結用ボルト４１により、ビーム部材２２を第１連結体２４の第１側部折曲げ部２４ｂに挿通させてフランジ付き六角ナット４２を螺合させて締め付ける場合には、フランジ付き六角ナット４２自身は第２連結体２５の六角穴２５ｆに嵌入されているため、単に、ビーム部材２２側から連結用ボルト４１を締め付けるだけで済み、したがって連結作業を容易に行うことができる。 When the beam member 22 is inserted into the first side bent portion 24b of the first connecting body 24 by the connecting bolt 41 and the flanged hex nut 42 is screwed and tightened, the flanged hex nut 42 is used. Since it is fitted in the hexagonal hole 25f of the second connecting body 25, it is only necessary to tighten the connecting bolt 41 from the beam member 22 side, so that the connecting operation can be easily performed.

さらに、この連結部構造においては、両連結体２４，２５同士は、係合突部２５ｄ，２５ｅと係合穴部２４ｄ，２４ｅとにより互いに係合されるとともに、これら両連結体２４，２５とビーム部材２２および柱部材３３との連結はボルト・ナットにより行われるため、溶接が一切不要になり、したがって製造が容易となる。 Furthermore, in this connection part structure, while both the connection bodies 24 and 25 are mutually engaged by the engagement protrusions 25d and 25e and the engagement hole parts 24d and 24e, Since the beam member 22 and the column member 33 are connected to each other by bolts and nuts, welding is not required at all, and the manufacture is facilitated.
