特許文献１〜３に記載の方法で梁部材同士を接合する場合、梁部材同士は互いに水平に接合される。つまり、接合する際に一方の梁部材の軸線に対して他方の梁部材の軸線の高さや角度等の位置を調整することは困難であった。 When the beam members are joined to each other by the method described in Patent Documents 1 to 3, the beam members are joined horizontally to each other. That is, it is difficult to adjust the positions such as the height and angle of the axis of the other beam member with respect to the axis of one beam member at the time of joining.

本発明は上記事実に鑑み、一方の梁部材の軸線に対して他方の梁部材の軸線をずれた位置にすることができる梁の接合構造を提供することを目的とする。 In view of the above facts, an object of the present invention is to provide a beam joining structure capable of shifting the axis of the other beam member from the axis of one beam member.

第一態様に記載の梁の接合構造は、端部に梁側ボルト孔が形成された２つ以上の梁部材を接合して構成される梁と、前記梁部材の上面又は下面にそれぞれ立設され、ガセット側ボルト孔が形成されたガセットプレートと、前記梁部材の端部間に跨り、プレート側ボルト孔が形成され、ボルトによって前記梁部材に固定されるプレートと、前記ガセットプレート間に跨り、アングル側ボルト孔が形成され、ボルトによって前記ガセットプレートに固定されるアングル材と、を備え、前記梁側ボルト孔及び前記プレート側ボルト孔の少なくとも一方、及び、前記ガセット側ボルト孔及び前記アングル側ボルト孔の少なくとも一方の内径と前記ボルトの雄ねじ部の外径との間には隙間が形成されており、前記隙間内において前記ボルトの位置を調整することで、一方の梁部材の軸線に対して他方の梁部材の軸線がずれた位置とされる。 The beam joining structure according to the first aspect is a beam formed by joining two or more beam members having beam-side bolt holes formed at their ends, and erected on the upper surface or the lower surface of the beam member, respectively. Straddle between the gusset plate on which the gusset side bolt hole is formed and the end of the beam member, and between the plate on which the plate side bolt hole is formed and fixed to the beam member by the bolt and the gusset plate. An angle member having an angle-side bolt hole formed and fixed to the gusset plate by a bolt, the beam-side bolt hole and at least one of the plate-side bolt holes, and the gusset-side bolt hole and the angle. A gap is formed between the inner diameter of at least one of the side bolt holes and the outer diameter of the male screw portion of the bolt, and by adjusting the position of the bolt in the gap, the axis of one beam member can be formed. On the other hand, the axis of the other beam member is deviated.

上記構成によれば、プレートを介して梁部材の端部同士をボルトで固定し、アングル材を介して梁部材に接合されたガセットプレート同士をボルトで接合することで、梁部材同士を接合することができる。 According to the above configuration, the ends of the beam members are fixed to each other with bolts via the plates, and the gusset plates joined to the beam members via the angle member are joined to each other with bolts to join the beam members to each other. be able to.

このとき、梁側ボルト孔及びプレート側ボルト孔の少なくとも一方、及び、ガセット側ボルト孔及びアングル側ボルト孔の少なくとも一方の内径とボルトの雄ねじ部の外径との間には隙間が形成されている。このため、隙間内においてボルトの位置を調整することで、一方の梁部材の軸線に対して他方の梁部材の軸線がずれた位置とすることができる。 At this time, a gap is formed between at least one of the beam-side bolt hole and the plate-side bolt hole, and at least one inner diameter of the gusset-side bolt hole and the angle-side bolt hole and the outer diameter of the male screw portion of the bolt. There is. Therefore, by adjusting the position of the bolt in the gap, it is possible to set the position where the axis of the other beam member deviates from the axis of the one beam member.

第二態様に記載の梁の接合構造は、第一態様に記載の梁の接合構造であって、前記梁は片持ち梁である The beam joining structure according to the second aspect is the beam joining structure according to the first aspect , and the beam is a cantilever.

上記構成によれば、梁が片持ち梁であるため、梁部材の接合部分で梁部材同士の軸線の位置を調整することにより、梁の自由端側の高さや角度を調整することができる。 According to the above configuration, since the beam is a cantilever, the height and angle of the free end side of the beam can be adjusted by adjusting the position of the axis line between the beam members at the joint portion of the beam members.

第三態様に記載の梁の接合構造は、第一態様又は第二態様に記載の梁の接合構造であって、一方の前記梁部材は、水平方向に対して角度を持たせて設けられており、他方の前記梁部材は、一方の前記梁部材の軸線に対して角度を持たせて接合されている。 The beam joining structure according to the third aspect is the beam joining structure according to the first aspect or the second aspect , and one of the beam members is provided at an angle with respect to the horizontal direction. The other beam member is joined at an angle with respect to the axis of the one beam member.

上記構成によれば、梁によって例えば屋根架構等の傾斜した構造物を構成する場合、水平方向に対して角度を持たせて設けられた一方の梁部材に対して、角度を持たせて他方の梁部材を接合することで、屋根架構の傾斜角度を調整することができる。 According to the above configuration, when a beam is used to form an inclined structure such as a roof frame, one beam member provided at an angle with respect to the horizontal direction is angled with the other. By joining the beam members, the inclination angle of the roof frame can be adjusted.

本発明によれば、一方の梁部材の軸線に対して他方の梁部材の軸線をずれた位置にすることができる。 According to the present invention, the axis of the other beam member can be displaced from the axis of the other beam member.

The gap (Dd) between the inner diameter D of the angle-side bolt hole 26A and the outer diameter d of the male screw portion 30A of the high-strength bolt 30 is the gap H between the gusset plates 20 and 22 and the beam members 12 and 14. It is made larger than the gap S between the lower flanges 12B and 14B and the angle member 26.

＜作用及び効果＞
本実施形態によれば、プレート２４を介して梁部材１２、１４の長手方向一端部同士を高力ボルト２８で固定し、アングル材２６を介して梁部材１２、１４に溶接されたガセットプレート２０、２２同士を高力ボルト３０で接合することで、梁部材１２、１４同士を接合することができる。 <Action and effect>
According to the present embodiment, the gusset plate 20 in which one ends of the beam members 12 and 14 in the longitudinal direction are fixed to each other via the plate 24 with high-strength bolts 28 and welded to the beam members 12 and 14 via the angle member 26. , 22 can be joined to each other by the high-strength bolt 30, and the beam members 12 and 14 can be joined to each other.

ここで、高力ボルト２８、３０が挿通される梁側ボルト孔１６、１８、プレート側ボルト孔２４Ａ、ガセット側ボルト孔２０Ａ、２２Ａ、及びアングル側ボルト孔２６Ａは、全て同一方向（水平方向）に形成されている。このため、各ボルト孔１６、１８、２０Ａ、２２Ａ、２４Ａ、２６Ａが同一方向に形成されていない構成と比較して、ボルト止めの作業性が向上する。 Here, the beam-side bolt holes 16 and 18, the plate-side bolt holes 24A, the gusset-side bolt holes 20A and 22A, and the angle-side bolt holes 26A through which the high-strength bolts 28 and 30 are inserted are all in the same direction (horizontal direction). Is formed in. Therefore, the workability of bolting is improved as compared with the configuration in which the bolt holes 16, 18, 20A, 22A, 24A, and 26A are not formed in the same direction.

また、プレート側ボルト孔２４Ａ及びアングル側ボルト孔２６Ａの内径Ｄと高力ボルト２８、３０の雄ねじ部２８Ａ、３０Ａの外径ｄとの隙間（Ｄ−ｄ）が、最大許容寸法とされている。これにより、高力ボルト２８、３０がプレート側ボルト孔２４Ａ内及びアングル側ボルト孔２６Ａ内で移動することにより、梁部材１２の軸線に対して梁部材１４の軸線をずれた位置にすることができる。 Further, the gap (D-d) between the inner diameter D of the plate-side bolt hole 24A and the angle-side bolt hole 26A and the outer diameter d of the male screw portions 28A and 30A of the high-strength bolts 28 and 30 is set as the maximum allowable dimension. .. As a result, the high-strength bolts 28 and 30 move in the plate-side bolt holes 24A and the angle-side bolt holes 26A, so that the axis of the beam member 14 is displaced from the axis of the beam member 12. it can.

具体的には、図２（Ｂ）に示すように、梁部材１２の軸線に対して梁部材１４の軸線の高さを調整することができる。このとき、図２（Ａ）に示すプレート側ボルト孔２４Ａ及びアングル側ボルト孔２６Ａの内径Ｄと高力ボルト２８、３０の雄ねじ部２８Ａ、３０Ａの外径ｄとの隙間（Ｄ−ｄ）が、図２（Ａ）に示す梁部材１２、１４の下フランジ１２Ｂ、１４Ｂとアングル材２６との隙間Ｓより大きくされている。このため、隙間Ｓの範囲で梁部材１４を移動させて、梁部材１２の軸線に対して梁部材１４の軸線の高さを変えることができる。 Specifically, as shown in FIG. 2B, the height of the axis of the beam member 14 can be adjusted with respect to the axis of the beam member 12. At this time, there is a gap (Dd) between the inner diameter D of the plate-side bolt hole 24A and the angle-side bolt hole 26A shown in FIG. 2A and the outer diameter d of the male screw portions 28A and 30A of the high-strength bolts 28 and 30. , The gap S between the lower flanges 12B and 14B of the beam members 12 and 14 and the angle member 26 shown in FIG. 2A is made larger. Therefore, the beam member 14 can be moved within the range of the gap S to change the height of the axis of the beam member 14 with respect to the axis of the beam member 12.

同様に、図２（Ｃ）に示すように、梁部材１２の軸線に対して梁部材１４の軸線の角度を調整することもできる。このとき、図２（Ａ）に示すプレート側ボルト孔２４Ａ及びアングル側ボルト孔２６Ａの内径Ｄと高力ボルト２８、３０の雄ねじ部２８Ａ、３０Ａの外径ｄとの隙間（Ｄ−ｄ）が、図２（Ａ）に示す梁部材１２、１４同士の隙間Ｈ、及びガセットプレート２０、２２同士の隙間Ｈより大きくされている。このため、隙間Ｈの範囲で梁部材１４を回動させて、梁部材１２の軸線に対して梁部材１４の軸線の角度を変えることができる。 Similarly, as shown in FIG. 2C, the angle of the axis of the beam member 14 with respect to the axis of the beam member 12 can be adjusted. At this time, there is a gap (Dd) between the inner diameter D of the plate-side bolt hole 24A and the angle-side bolt hole 26A shown in FIG. 2A and the outer diameter d of the male screw portions 28A and 30A of the high-strength bolts 28 and 30. , The gap H between the beam members 12 and 14 shown in FIG. 2A and the gap H between the gusset plates 20 and 22 are made larger. Therefore, the beam member 14 can be rotated within the range of the gap H to change the angle of the axis of the beam member 14 with respect to the axis of the beam member 12.
