Description
本発明は、鋼管柱に対して、異なる高さの梁を接合するための柱と梁との接合構造に関するものである。 The present invention relates to a column-to-beam joint structure for joining beams having different heights to a steel pipe column.
従来、鋼管柱を用いた構造物において、H形鋼からなる梁を接合する場合がある。柱と梁とを接合する場合には、接合部において、梁からの応力を柱に効率良く伝達させるために、梁のフランジ部の高さに応じた通しダイアフラムが設けられる。通しダイアフラムは、柱と柱の間に溶接等で接合される板状部材である。通常、梁のフランジ部は、通しダイアフラムの側面で突きあわされて溶接される。 Conventionally, in a structure using a steel pipe column, a beam made of H-shaped steel may be joined. When joining a column and a beam, a through diaphragm corresponding to the height of the flange portion of the beam is provided in order to efficiently transmit stress from the beam to the column at the junction. The through diaphragm is a plate-like member joined between the pillars by welding or the like. Usually, the flange portion of the beam is welded against the side of the through diaphragm.
しかし、柱に接合される梁のサイズ(高さ)が全ての方向で同じではない場合がある。例えば、一方向の梁のみ、高さが低い梁を接合する場合がある。このような場合には、当該梁の上下のフランジ部のうち、少なくとも一方は他の梁が接合される通しダイアフラムと接合することができない。 However, the size (height) of the beam joined to the column may not be the same in all directions. For example, a beam having a low height may be joined only in one direction. In such a case, at least one of the upper and lower flange portions of the beam cannot be joined to the through diaphragm to which the other beam is joined.
したがって、このような高さの異なる梁を接合するためには柱内部に内ダイアフラムを接合する等の必要がある。 Therefore, in order to join such beams having different heights, it is necessary to join an inner diaphragm inside the column.
また、このような高さの異なる梁を接合するための柱梁接合構造として、角形断面管と、該角形断面管の並行する2辺を支持する十字プレートと、該角形断面管の角部を挟む2辺を支持する斜めプレートとが鋳造により一体的に成形され、且つ外周面の少なくとも梁が取り付けられる範囲が平坦に形成された柱梁接合金物の端部が角形断面管からなる柱に溶接接合され、H形鋼からなる梁が前記柱梁接合金物の外周面にノンスカラップ溶接により接合される柱梁接合構造がある(特許文献1)。 Moreover, as a column beam connection structure for joining such beams having different heights, a square cross-section tube, a cross plate supporting two parallel sides of the square cross-section tube, and a corner portion of the square cross-section tube are provided. The ends of the beam-to-column fittings, which are integrally formed by casting with the diagonal plates that support the two sides sandwiched, and at least the beam mounting range on the outer peripheral surface is formed flat, are welded to a column made of a square section tube. There is a beam-to-column connection structure in which a beam made of H-shaped steel is bonded to the outer peripheral surface of the beam-to-column metal fitting by non-scallop welding (Patent Document 1).
しかし、柱内部に内ダイアフラムを設ける作業は、溶接量が多く、作業性が悪いという問題がある。また、特許文献1に記載の構造では、柱梁接合部を一体成型する必要があり、金物の質量が大きくなるとともに高価なものとなる。 However, the work of providing the inner diaphragm inside the column has a problem that the welding amount is large and workability is poor. Further, in the structure described in Patent Document 1, it is necessary to integrally form the beam-column joint, which increases the mass of the hardware and increases the cost.
本発明は、このような問題に鑑みてなされたもので、異なる高さの梁を柱に接合する場合において、柱内部にダイアフラム等の部材を接合することなく、また、特殊な構造の柱梁接合金物を用いることなく、簡易な構造で柱の外部のみで作業が可能な柱と梁との接合構造を提供することを目的とする。 The present invention has been made in view of such problems, and in the case where beams having different heights are joined to a column, a column beam having a special structure can be used without joining a member such as a diaphragm inside the column. It is an object of the present invention to provide a joint structure between a column and a beam that can be operated only with the outside of the column with a simple structure without using a joint metal.
前述した目的を達成するため、本発明は、柱と梁との接合構造であって、柱に形成される一対のダイアフラムと、上下の前記ダイアフラムにそれぞれのフランジ部が接合される第1の梁と、前記第1の梁と高さが異なり、前記第1の梁とは異なる方向に前記柱と接合される第2の梁と、前記柱の外面に設けられ、前記柱の外面からの前記ダイアフラムの突出量と略同一の厚みであって、前記ダイアフラムと略同一幅の本体部と、前記本体部の少なくとも一方の端部において、前記突出量と略同一幅であって、前記本体部の厚み方向に形成される凸部とを有する接合部材と、を具備し、前記第2の梁の一方のフランジ部は一方の前記ダイアフラムと接合され、前記接合部材の前記本体部および前記凸部は、前記柱と他方の前記ダイアフラムに接合され、前記第2の梁の他方のフランジ部が前記接合部材に接合され、前記接合部材を介して、前記第2の梁の他方のフランジ部と他方の前記ダイアフラムとの間の応力伝達が行われることを特徴とする柱と梁との接合構造である。 In order to achieve the above-described object, the present invention is a structure for joining a column and a beam, and includes a pair of diaphragms formed on the columns, and a first beam in which each flange portion is joined to the upper and lower diaphragms. And a second beam having a height different from that of the first beam and joined to the column in a direction different from that of the first beam, and provided on an outer surface of the column, and from the outer surface of the column A main body having substantially the same thickness as the protrusion of the diaphragm, and having a width approximately the same as that of the diaphragm, and at least one end of the main body having the same width as the protrusion; A joining member having a convex part formed in the thickness direction, one flange part of the second beam is joined to one diaphragm, and the main body part and the convex part of the joining member are The column and the other diaphragm The other flange portion of the second beam is joined to the joining member, and stress is transmitted between the other flange portion of the second beam and the other diaphragm via the joining member. It is a joint structure of columns and beams characterized by
前記凸部は、前記接合部材の一方の端部に形成され、前記第2の梁は、前記柱に対して幅方向に偏心して接合され、前記凸部は、前記第2の梁が接合される前記柱の面とは垂直な面であって、前記第2の梁の偏心方向の、前記柱および他方の前記ダイアフラムに接合されてもよい。 The convex portion is formed at one end of the joining member, the second beam is joined eccentrically in the width direction with respect to the column, and the convex portion is joined to the second beam. The surface of the column may be a surface perpendicular to the column and may be joined to the column and the other diaphragm in the eccentric direction of the second beam.
前記凸部は、前記接合部材の両端に形成され、両側の前記凸部は、前記第2の梁が接合される前記柱の面とは垂直な方向の、柱および他方の前記ダイアフラムにそれぞれ接合されてもよい。 The convex portions are formed at both ends of the joining member, and the convex portions on both sides are joined to the pillar and the other diaphragm in a direction perpendicular to the surface of the pillar to which the second beam is joined. May be.
前記凸部の長さは、前記柱の幅の1/2以下であることが望ましい。 As for the length of the convex part, it is desirable that it is 1/2 or less of the width of the pillar.
前記柱は、断面外形が略矩形であり、角部が曲面部で構成され、前記凸部の内面形状は、前記曲面部の形状に略対応した凹曲面部を有し、前記凹曲面部の曲率半径は、前記曲面部の曲率半径よりも小さいことが望ましい。 The column has a substantially rectangular cross-sectional outer shape, a corner portion is formed by a curved surface portion, and an inner surface shape of the convex portion has a concave curved surface portion substantially corresponding to a shape of the curved surface portion. It is desirable that the radius of curvature is smaller than the radius of curvature of the curved surface portion.
本発明によれば、柱と梁との接合部が、柱の外部に設けられる梁接合部材によって行われるため、柱の外部のみで作業を行うことが可能である。したがって、柱への梁の接合作業性に優れる。特に、梁接合部材の本体部が、柱からのダイアフラムの突出量と略同厚みであり、凸部の幅が突出量と略同幅とすることで、ダイアフラムに対して容易に接合可能である。また、本体部の高さは、梁のフランジ部とダイアフラムとの距離に応じて適宜設定できるため、フランジ部とダイアフラムとの距離が短い場合であっても容易に適用が可能である。 According to the present invention, since the joint between the column and the beam is performed by the beam joining member provided outside the column, the work can be performed only outside the column. Therefore, the workability of joining the beam to the column is excellent. In particular, the main body portion of the beam joining member has substantially the same thickness as the protruding amount of the diaphragm from the column, and the protruding portion has substantially the same width as the protruding amount, so that it can be easily joined to the diaphragm. . Moreover, since the height of the main body can be appropriately set according to the distance between the flange portion of the beam and the diaphragm, it can be easily applied even when the distance between the flange portion and the diaphragm is short.
また、梁を柱に対して偏心させて接合する場合には、本体部に対して、凸部を一方の端部にのみ形成すればよい。このようにすることで、簡易な構造で確実に梁からの応力を柱に伝達することができる。また、凸部を両端に形成することで、梁を柱の幅方向の中央付近に接合する場合にも、確実に梁からの応力を柱に伝達することができる。 Further, when the beam is decentered with respect to the column and joined, the convex portion may be formed only at one end portion with respect to the main body portion. By doing in this way, the stress from a beam can be reliably transmitted to a column with a simple structure. Further, by forming the convex portions at both ends, the stress from the beam can be reliably transmitted to the column even when the beam is joined near the center in the width direction of the column.
また、凸部の長さが、柱の幅の1/2以下であれば、柱の対向する側面に、それぞれ梁接合部材を配置しても、互いの凸部が干渉することがない。また、凸部の内面の凹曲面部の曲率半径を、柱の角部の曲面部の曲率半径よりも小さくすることで、凸部先端部と柱との間に隙間が形成されることがない。 Moreover, if the length of a convex part is 1/2 or less of the width | variety of a pillar, even if it arrange | positions a beam joining member to the side surface which a pillar opposes, a mutual convex part does not interfere. Further, by making the curvature radius of the concave curved surface portion of the inner surface of the convex portion smaller than the curvature radius of the curved surface portion of the corner portion of the column, no gap is formed between the tip portion of the convex portion and the column. .
本発明によれば、異なる高さの梁を柱に接合する場合において、柱内部にダイアフラム等の部材を接合することなく、また、特殊な構造の柱梁接合金物を用いることなく、簡易な構造で柱の外部のみで作業が可能な柱と梁との接合構造を提供することができる。 According to the present invention, when a beam having a different height is joined to a column, a simple structure can be obtained without joining a member such as a diaphragm inside the column, and without using a specially-structured column beam joint hardware. Therefore, it is possible to provide a joint structure between a column and a beam that can be operated only outside the column.
以下、本発明の実施の形態にかかる柱と梁の接合構造1について説明する。図1は、柱と梁の接合構造1を示す斜視図である。柱と梁の接合構造1は、柱5に複数の梁9a、9bが接合された構造である。 Hereinafter, a column-to-beam joint structure 1 according to an embodiment of the present invention will be described. FIG. 1 is a perspective view showing a pillar-to-beam joint structure 1. The pillar-to-beam joint structure 1 is a structure in which a plurality of beams 9 a and 9 b are joined to a pillar 5.
柱5は中空の角形鋼管柱であり、梁9a、9bはH形鋼である。梁9aと梁9bとは、梁の高さが異なる。なお、図1の例では、梁9aが柱5の一方向に形成され、梁9bがこれと隣り合う一方向に形成される例を示すが、本発明ではこれに限られず、梁9bを複数方向に設けてもよい。 The column 5 is a hollow rectangular steel tube column, and the beams 9a and 9b are H-shaped steel. The beam 9a and the beam 9b have different beam heights. 1 shows an example in which the beam 9a is formed in one direction of the column 5 and the beam 9b is formed in one direction adjacent thereto, but the present invention is not limited to this, and a plurality of beams 9b are formed. It may be provided in the direction.
柱5には、一対のダイアフラム3a、3bが接合される。なお、ダイアフラム3a、3bは、柱5の外方に突出する通しダイアフラムである。ダイアフラム3a、3bは、柱5に所定の間隔をあけて上下に設けられる。 A pair of diaphragms 3 a and 3 b are joined to the column 5. The diaphragms 3 a and 3 b are through-diaphragms that protrude outward from the column 5. The diaphragms 3a and 3b are provided above and below the pillar 5 with a predetermined interval.
梁9aの上下のフランジ部の端部は、それぞれダイアフラム3a、3bと溶接によって接合される。すなわち、ダイアフラム3a、3bの設置間隔は梁9aのフランジ部間隔と一致する。したがって、梁9aからの応力を柱に確実に伝達することができる。 The ends of the upper and lower flange portions of the beam 9a are joined to the diaphragms 3a and 3b by welding, respectively. That is, the installation interval of the diaphragms 3a and 3b coincides with the flange portion interval of the beam 9a. Therefore, the stress from the beam 9a can be reliably transmitted to the column.
梁9bの上方のフランジ部11aの端部は、上方のダイアフラム3aと溶接によって接合される。梁9bは梁9aよりも高さが低いため、梁9bの下方のフランジ部11bとダイアフラム3bとの間には隙間が生じる。 The end of the flange portion 11a above the beam 9b is joined to the upper diaphragm 3a by welding. Since the beam 9b is lower than the beam 9a, a gap is generated between the flange portion 11b below the beam 9b and the diaphragm 3b.
ダイアフラム3bと梁9bのフランジ部11bとの間には、梁接合部材13が接合される。すなわち、梁接合部材13を介して梁9bのフランジ部11bとダイアフラム3bおよび柱5とが接合される。したがって、梁9bからの応力を柱に確実に伝達することができる。 A beam joining member 13 is joined between the diaphragm 3b and the flange portion 11b of the beam 9b. That is, the flange portion 11b of the beam 9b, the diaphragm 3b, and the column 5 are joined via the beam joining member 13. Therefore, the stress from the beam 9b can be reliably transmitted to the column.
図2は、梁接合部材13を示す図であり、図2(a)は斜視図、図2(b)は平面図である。梁接合部材13は、略直方体である本体部15と、凸部17とから構成される。梁接合部材13は、例えば溶接性に優れる鋼材である。なお、図では、本体部15を直方体で示すが、後述する溶接部に対して開先や溶接余盛を避けるための切欠き形状を形成してもよい。 2A and 2B are views showing the beam joining member 13, in which FIG. 2A is a perspective view and FIG. 2B is a plan view. The beam joining member 13 includes a main body portion 15 that is a substantially rectangular parallelepiped and a convex portion 17. The beam joining member 13 is a steel material having excellent weldability, for example. In addition, in the figure, although the main-body part 15 is shown by a rectangular parallelepiped, you may form the notch shape for avoiding a groove | channel and a welding surplus with respect to the welding part mentioned later.
本体部15の幅方向(図2(b)の左右方向)の両端部には、本体部15の高さ方向(図2(a)の上下方向)に沿って、幅方向に垂直な方向(厚み方向)の一方に突出する一対の凸部17が設けられる。凸部17の内面側であって、凸部17の基部近傍には、円弧状である凹曲面部16が形成される。 At both ends in the width direction of the main body 15 (the left-right direction in FIG. 2B), the direction perpendicular to the width direction (the vertical direction in FIG. 2A) (the vertical direction in FIG. 2A) ( A pair of convex portions 17 projecting on one side (in the thickness direction) are provided. A concave curved surface portion 16 having an arc shape is formed on the inner surface side of the convex portion 17 and in the vicinity of the base portion of the convex portion 17.
図3(a)は、図1のA−A線断面図であり、図3(b)は、図1のB−B線断面図である。図3(a)に示すように、梁接合部材13は、側面が梁9bのフランジ部11bの先端と接触して、溶接部19で溶接される。また、梁接合部材13は、凸部17の上部および本体部15の上部が柱5に溶接部19で接合される。さらに、梁接合部材13の凸部17の下部および本体部15の下部が、ダイアフラム3bと溶接部19で溶接される。 3A is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 3B is a cross-sectional view taken along the line BB in FIG. As shown in FIG. 3A, the beam joining member 13 is welded at the welded portion 19 with the side surface contacting the tip of the flange portion 11b of the beam 9b. Further, in the beam joining member 13, the upper part of the convex part 17 and the upper part of the main body part 15 are joined to the column 5 by the welding part 19. Furthermore, the lower part of the convex part 17 and the lower part of the main-body part 15 of the beam joining member 13 are welded by the diaphragm 3b and the welding part 19. FIG.
なお、図3(a)に示すように、梁接合部材13が接合される部位に対応する梁9bには、あらかじめ切欠き部が形成される。このため、梁接合部材13と梁9bとが干渉することがない。また、図3(b)に示すように、梁接合部材13の全幅は、ダイアフラム3bの全幅と略一致する。 In addition, as shown to Fig.3 (a), the notch part is previously formed in the beam 9b corresponding to the site | part to which the beam joining member 13 is joined. For this reason, the beam joining member 13 and the beam 9b do not interfere with each other. Further, as shown in FIG. 3B, the full width of the beam joining member 13 substantially matches the full width of the diaphragm 3b.
図4は、図3(b)のC−C線断面図である。梁接合部材13の本体部15の厚みT(図2(b))は、柱5に対してダイアフラム3bの突出代と略一致する。また、凸部17の幅W(図2(b))は、柱5に対してダイアフラム3bの突出代と略一致する。したがって、ダイアフラム3b上に梁接合部材13を配置すると、本体部15および凸部17の外面は、ダイアフラム3bからはみ出すことがない。したがって、溶接等が容易である。なお、各溶接部においては、必要に応じて図示を省略した裏当金が用いられる。 FIG. 4 is a cross-sectional view taken along the line CC of FIG. The thickness T (FIG. 2B) of the main body portion 15 of the beam joining member 13 substantially coincides with the protrusion margin of the diaphragm 3 b with respect to the column 5. Further, the width W (FIG. 2B) of the convex portion 17 substantially coincides with the protrusion margin of the diaphragm 3 b with respect to the column 5. Therefore, when the beam joining member 13 is disposed on the diaphragm 3b, the outer surfaces of the main body portion 15 and the convex portion 17 do not protrude from the diaphragm 3b. Therefore, welding or the like is easy. In each welded portion, a backing metal (not shown) is used as necessary.
また、凸部17の内面の凹曲面部16は、曲面部7に沿って配置される。ここで、凸部17の内面側の凹曲面部16は、曲面部7に対応する形状であり、その曲率半径R1(図2(b))は、柱5の曲面部7の曲率半径R2(図4)よりも僅かに小さく設定される。R1がR2よりも大きくなると、凸部17の先端部や、本体部15の内面が、柱5と接触しなくなるためである。 The concave curved surface portion 16 on the inner surface of the convex portion 17 is disposed along the curved surface portion 7. Here, the concave curved surface portion 16 on the inner surface side of the convex portion 17 has a shape corresponding to the curved surface portion 7, and its curvature radius R 1 (FIG. 2B) is a curvature radius R 2 ( It is set slightly smaller than FIG. This is because when R1 is larger than R2, the tip end portion of the convex portion 17 and the inner surface of the main body portion 15 do not come into contact with the column 5.
なお、凹曲面部16と曲面部7との間には、多少の隙間が形成されてもよい。また、柱5、梁9bとの適切な溶接代を示すため、本体部15および凸部17に、溶接部を示すテーパ部等を形成してもよい。 A slight gap may be formed between the concave curved surface portion 16 and the curved surface portion 7. Moreover, in order to show the appropriate welding allowance with the pillar 5 and the beam 9b, you may form the taper part etc. which show a welding part in the main-body part 15 and the convex part 17. FIG.
凸部17の長さL(図2(b))は、柱5の全幅の1/2以下である。なお、凸部17の長さLとは、本体部の内面からの突出代を指す。このようにすることで、一対の梁接合部材13を柱に対して対向して接合することができる。 The length L of the convex portion 17 (FIG. 2B) is ½ or less of the full width of the column 5. In addition, the length L of the convex part 17 points out the protrusion margin from the inner surface of a main-body part. By doing in this way, a pair of beam joining member 13 can be joined facing a pillar.
例えば、図4において、柱5の左側の梁9aが、梁9bと同様の態様である場合(この場合には、他の方向に梁9aが接合される)、梁接合部材13は、柱5を左右から挟み込むように一対対向して接合する必要がある。この場合、梁接合部材13の凸部17の長さLが柱5の全幅の1/2以下であれば、凸部17同士が干渉することがない。 For example, in FIG. 4, when the beam 9a on the left side of the column 5 is in the same mode as the beam 9b (in this case, the beam 9a is bonded in the other direction), the beam connecting member 13 is It is necessary to join a pair so as to sandwich them from the left and right. In this case, if the length L of the convex part 17 of the beam joining member 13 is ½ or less of the full width of the column 5, the convex parts 17 do not interfere with each other.
このように、ダイアフラム3bと梁9bとの間に梁接合部材13を設けることで、梁9bからの下方に向かう応力や、ダイアフラム3aとの接合部を起点としたモーメント等を確実に柱5に伝達することができる。また、梁接合部材13の厚みは、梁9bとダイアフラム3bとの距離に応じて適宜設定することができる。したがって、梁9bとダイアフラム3bとの距離が狭い場合であっても、梁9bからの柱5への応力伝達手段として適用することができる。 Thus, by providing the beam joining member 13 between the diaphragm 3b and the beam 9b, the downward stress from the beam 9b, the moment starting from the joint with the diaphragm 3a, and the like can be reliably applied to the column 5. Can communicate. Moreover, the thickness of the beam joining member 13 can be appropriately set according to the distance between the beam 9b and the diaphragm 3b. Therefore, even when the distance between the beam 9b and the diaphragm 3b is narrow, it can be applied as a means for transmitting stress from the beam 9b to the column 5.
また、梁接合部材13は、両端部に凸部17を有するため、柱5の3辺方向に対して接合することができる。すなわち、梁9bが接合される側のみではなく、これと垂直な方向の柱5、ダイアフラム3bとも接合される。したがって、ダイアフラム3bの変形が抑制され、梁9bからの応力を効率良く柱5に伝達することができる。 Moreover, since the beam joining member 13 has the convex parts 17 at both ends, it can be joined to the three sides of the column 5. That is, not only the side to which the beam 9b is joined, but also the column 5 and the diaphragm 3b in a direction perpendicular thereto are joined. Therefore, the deformation of the diaphragm 3b is suppressed, and the stress from the beam 9b can be efficiently transmitted to the column 5.
なお、本実施の形態では、梁9bが梁9aよりも高さが低い例を示したが、梁9bが梁9aよりも高い場合でも本発明は適用可能である。この場合には、梁9bのウェブを所定範囲切欠いて、梁接合部材13を柱5およびダイアフラム3b下面等に接合すればよい。 In the present embodiment, the beam 9b has a lower height than the beam 9a. However, the present invention can be applied even when the beam 9b is higher than the beam 9a. In this case, the web of the beam 9b may be cut out in a predetermined range, and the beam joining member 13 may be joined to the column 5 and the lower surface of the diaphragm 3b.
また、梁接合部材13は、梁9bの下部に設置する必要はなく、上部に設けてもよい。この場合には、図3の上下が反転した状態で、梁9bと梁接合部材13とを接合すればよい。 Moreover, the beam joining member 13 does not need to be installed in the lower part of the beam 9b, and may be provided in the upper part. In this case, what is necessary is just to join the beam 9b and the beam joining member 13 in the state which the upper and lower sides of FIG.
次に、柱と梁との接合構造1の変形例を示す。なお、以下の説明において、柱と梁との接合構造1と同様の機能を奏する構成については図1〜図4と同一の符号を付し、重複する説明を省略する。 Next, a modified example of the column-to-beam joint structure 1 is shown. In addition, in the following description, about the structure which show | plays the function similar to the junction structure 1 of a pillar and a beam, the code | symbol same as FIGS. 1-4 is attached | subjected, and the overlapping description is abbreviate | omitted.
図5は、梁接合部材13aを示す図であり、図3(a)は斜視図、図3(b)は平面図である。梁接合部材13aは、梁接合部材13と略同様の構成であるが、凸部17が、本体部15の一方の端部側にのみ形成される点で異なる。すなわち、梁接合部材13が略コの字状であるのに対し、梁接合部材13aは略Lの字状部材である。なお、本体部の幅、厚み、凸部17の長さや凸部内面の曲率半径等は、梁接合部材13と同様である。 5A and 5B are views showing the beam joining member 13a, in which FIG. 3A is a perspective view and FIG. 3B is a plan view. The beam joining member 13 a has substantially the same configuration as the beam joining member 13, but differs in that the convex portion 17 is formed only on one end side of the main body portion 15. That is, the beam joining member 13 is substantially U-shaped, whereas the beam joining member 13a is a substantially L-shaped member. The width and thickness of the main body, the length of the convex portion 17 and the radius of curvature of the inner surface of the convex portion are the same as those of the beam joining member 13.
図6は、梁接合部材13に代えて梁接合部材13aを用いた柱と梁の接合構造1aを示す図(図4に対応する)である。梁接合部材13aは、梁接合部材13と略同様にして、ダイアフラム3b、柱5、梁9bと接合されるが、梁9bの接合位置が、柱と梁の接合構造1とは異なる。 FIG. 6 is a diagram (corresponding to FIG. 4) showing a column-to-beam joint structure 1 a using a beam joint member 13 a instead of the beam joint member 13. The beam joining member 13a is joined to the diaphragm 3b, the column 5, and the beam 9b in substantially the same manner as the beam joining member 13, but the joining position of the beam 9b is different from the joining structure 1 of the column and the beam.
柱と梁の接合構造1aでは、梁9bが柱5の幅方向に偏心して配置される。すなわち、柱5の一方の側面(図中下側)と、梁9b(フランジ部11b)の一方の側面(図中下側)とを一致させるように、梁9bが柱5に対して偏心した位置に配置される。 In the column-beam joint structure 1 a, the beam 9 b is arranged eccentrically in the width direction of the column 5. That is, the beam 9b is eccentric with respect to the column 5 so that one side surface (lower side in the drawing) of the column 5 and one side surface (lower side in the drawing) of the beam 9b (flange portion 11b) coincide with each other. Placed in position.
梁接合部材13aに形成される凸部17は、梁9bの偏心方向側に配置される。したがって、ダイアフラム3bの変形が抑制され、梁9bからの応力を効率良く柱5に伝達することができる。 The convex portion 17 formed on the beam joining member 13a is disposed on the eccentric direction side of the beam 9b. Therefore, the deformation of the diaphragm 3b is suppressed, and the stress from the beam 9b can be efficiently transmitted to the column 5.
なお、梁9bの偏心方向とは逆側(図中上方)には、凸部17が形成されず、本体部15のみがダイアフラム3bに接合される。したがって、凸部17が形成されていない側においては、凸部17が形成されている側と比較して、梁接合部材13aを介した梁9bから柱5への応力伝達が劣る。しかし、凸部17の形成されていない側は、梁9bの接合部から遠いため、その影響は小さい。したがって、梁9bが接合される側に凸部17を配置することで、効率良く梁9bから柱5への応力を伝達することができる。 Note that the convex portion 17 is not formed on the side opposite to the eccentric direction of the beam 9b (upward in the figure), and only the main body portion 15 is joined to the diaphragm 3b. Therefore, on the side where the convex portion 17 is not formed, the stress transmission from the beam 9b to the column 5 via the beam joining member 13a is inferior to the side where the convex portion 17 is formed. However, since the side where the convex part 17 is not formed is far from the joint part of the beam 9b, the influence is small. Therefore, the stress from the beam 9b to the column 5 can be efficiently transmitted by arranging the convex portion 17 on the side to which the beam 9b is joined.
以上、添付図を参照しながら、本発明の実施の形態を説明したが、本発明の技術的範囲は、前述した実施の形態に左右されない。当業者であれば、特許請求の範囲に記載された技術的思想の範疇内において各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。 As mentioned above, although embodiment of this invention was described referring an accompanying drawing, the technical scope of this invention is not influenced by embodiment mentioned above. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the technical idea described in the claims, and these are naturally within the technical scope of the present invention. It is understood that it belongs.
例えば、補強部材13においては、凸部17の内面を凹曲面部16としたが、当該部位は、必ずしも曲面でなくてもよい。たとえば、凸部17の内面を複数の直線を結んで形成してもよく、またはテーパ形状としてもよい。この場合にも、補強部材を柱5に接合した際に、凸部17の内面が曲面部7と干渉しなければよい。 For example, in the reinforcing member 13, the inner surface of the convex portion 17 is the concave curved surface portion 16, but the portion may not necessarily be a curved surface. For example, the inner surface of the convex portion 17 may be formed by connecting a plurality of straight lines, or may be tapered. Also in this case, when the reinforcing member is joined to the column 5, the inner surface of the convex portion 17 may not interfere with the curved surface portion 7.
