Abstract

This coupling structure and construction structure body pertain to a coupling structure in which two structure members 1, 2 are connected. Each structure member 1, 2 has integrated projecting parts 32, 42 projecting from one side part (A side or B side). The two structure members 1, 2 are brought together, and the projecting parts 32, 42 are overlapped on the side parts (A side or B side) of the counterpart structure member 2, 1 so as to be positioned on opposite sides from each other. The projecting parts 32, 42 and the side parts (A side or B side) of the counterpart structure members 2, 1 are each joined with bolts. A coupling with a simple process is thereby provided in which, primarily, the number of components used for connecting construction members is reduced, and there is no projection beyond the (flange parts of the) structure members.

Description

継手構造および建築用構造体Joint structure and architectural structure
 この発明は、継手構造および建築用構造体に関するものである。 The present invention relates to a joint structure and an architectural structure.
 例えば、ビルなどの建築物ではその骨組に、鉄骨などの構造材が使われている。このような構造材は、建築物に合わせて組まれることで上記した骨組(建築用構造体)となる。 For example, a building such as a building uses a structural material such as a steel frame for its framework. Such a structural material becomes the above-described framework (structural structure) by being assembled according to the building.
 そして、構造材を組む際に、構造材どうしの接続は、構造材どうしの接続部分に添え板を当ててボルトで固定するようにしていた(例えば、特許文献1~特許文献5参照)。 And, when assembling the structural material, the structural materials are connected with each other by attaching a plate to the connecting portion between the structural materials and fixing them with bolts (for example, see Patent Documents 1 to 5).
特開2012-57450号公報JP 2012-57450 A 特開2012-127165号公報JP 2012-127165 A 特開平6-173340号公報JP-A-6-173340 特開昭51-32006号公報JP 51-32006 特開昭62-175107号公報JP 62-175107 A
 しかしながら、上記各特許文献のように添え板を用いて構造材の接続を行う場合、構造材とは別に多数枚の添え板が必要となるので、使用する部品の点数が多くなっていた。また、多数の添え板を固定するのに多数本のボルトが必要になっていた。そして、ボルトを固定するのに多大な手間がかかっていた。 However, when connecting a structural material using a base plate as in each of the above-mentioned patent documents, a large number of base plates are required separately from the structural material, so that the number of parts used is large. In addition, a large number of bolts are required to fix a large number of attachment plates. And it took a lot of time to fix the bolts.
 そこで、本発明は、主に、上記した問題点を解決することを目的としている。 Therefore, the present invention mainly aims to solve the above-mentioned problems.
 上記課題を解決するために、本発明は、2本の構造材が接続された継手構造において、前記各構造材が、片側の側部から突出する突出部をそれぞれ一体に有しており、2本の前記構造材が互いに近接され、前記各突出部が互いに反対側に位置するように相手方の前記構造材の側部に重ね合わされると共に、前記各突出部と相手方の前記構造材の側部との間が、それぞれボルト接合によって固定されていることを特徴とする。 In order to solve the above-described problems, the present invention provides a joint structure in which two structural members are connected, and each of the structural members integrally includes a protruding portion that protrudes from one side portion. The structural members of the book are placed close to each other, and are superimposed on the side portions of the mating structural material so that the projecting portions are located on the opposite sides, and each projecting portion and the side portion of the mating structural material Between the two is fixed by bolt joints.
 本発明によれば、上記構成によって、構造材の接続に使用する部品の点数を少なくすると共に、構造材(のフランジ部)からの突出をなくし、施工が容易な継手を提供することができる。 According to the present invention, according to the above configuration, it is possible to provide a joint that can be easily constructed by reducing the number of parts used for connecting the structural material and eliminating the protrusion from the structural material (the flange portion thereof).

Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 11 are for explaining this embodiment.
 <構成>以下、構成について説明する。 <Configuration> The configuration will be described below.
 例えば、ビルなどの建築物の骨組に鉄骨(鋼材)などの構造材を用いる。この構造材を、建築物に合わせて組むことで建築物の骨組(建築用構造体)を構築する。構造材を組む際には、構造材どうしを接続する(または、継手構造を設ける)必要がある。 For example, a structural material such as a steel frame (steel material) is used for a framework of a building or the like. A structural framework (building structure) is constructed by assembling this structural material in accordance with the building. When assembling the structural material, it is necessary to connect the structural materials (or provide a joint structure).
 そして、以上のような基本的な構成に対し、この実施例は、以下のような構成を備えている。 In addition to the basic configuration as described above, this embodiment has the following configuration.
 (1)まず、構造材どうしの継手構造について説明する。 (1) First, the joint structure between structural materials will be described.
 この実施例の継手構造は、例えば、図1に示すように(図2~図4も併せて参照)、2本の構造材1,2を接続したものである。
 継手構造は、各構造材1,2が、片側の側部(A側またはB側)から突出する突出部32,42を一体に有している。
 そして、2本の構造材1,2が互いに近接され、各突出部32,42が互いに反対側に位置するように相手方の構造材2,1の側部(A側またはB側)に重ね合わされる。
 そして、各突出部32,42と相手方の構造材2,1の側部との間が、それぞれボルト接合によって固定される。
The joint structure of this embodiment is obtained by connecting two structural members 1 and 2 as shown in FIG. 1 (see also FIGS. 2 to 4).
In the joint structure, the structural members 1 and 2 integrally have protrusions 32 and 42 protruding from one side (A side or B side).
Then, the two structural materials 1 and 2 are brought close to each other, and are superposed on the side portion (A side or B side) of the other structural material 2 and 1 so that the projecting portions 32 and 42 are located on the opposite sides. The
And between each protrusion part 32 and 42 and the side part of the other structural material 2 and 1 is each fixed by bolt joining.
 ここで、2本の構造材1,2には、それぞれほぼ同じ断面形状を有するものが使われる。構造材1,2は、主に鉄骨(鋼材)やアルミ材などの各種の金属材を想定しているが、状況によっては、木材や、樹脂や、その他の素材や、これらのいずれかを用いた複合材などとすることが可能である。図では構造材1,2は、ほぼ水平方向へ直線状に延びるものとされている。この場合、図中、構造材1,2の左右の面が、構造材1,2の側部(A側またはB側)となっている。これに対し、図中、構造材1,2の上下の面を、構造材1,2の縁部(または縁面)とする。 Here, as the two structural materials 1 and 2, those having substantially the same cross-sectional shape are used. The structural materials 1 and 2 are mainly assumed to be various metal materials such as steel frames (steel materials) and aluminum materials, but depending on the situation, wood, resin, other materials, or any of these may be used. Composite material or the like. In the figure, the structural members 1 and 2 extend linearly in a substantially horizontal direction. In this case, in the drawing, the left and right surfaces of the structural materials 1 and 2 are side portions (A side or B side) of the structural materials 1 and 2. On the other hand, in the figure, the upper and lower surfaces of the structural materials 1 and 2 are defined as edges (or edge surfaces) of the structural materials 1 and 2.
 突出部32,42は、構造材1,2と強度的に一体と見做せる程度に構造材1,2に対して強固に固定されたものとする。突出部32,42は、構造材1,2の(図中上下の)縁部(縁面)を(図中上下方向に)越えない範囲内で(即ち、広がらないように、曲がらないように)突出したものとするのが好ましい。 Suppose that the projecting portions 32 and 42 are firmly fixed to the structural materials 1 and 2 to such an extent that they can be considered to be integral with the structural materials 1 and 2. The protrusions 32 and 42 do not bend so that they do not extend (that is, do not spread) within the range (in the vertical direction in the drawing) of the structural members 1 and 2 (up and down in the drawing). ) It is preferable to project.
 構造材1,2を近接配置する際には、突出部32,42が互いに平行になるようにする。 When the structural members 1 and 2 are arranged close to each other, the protrusions 32 and 42 are made parallel to each other.
 ボルト接合は、主に、ボルトおよびナットなどの締結具51を用いた接合(またはリベット結合)などのことである。ボルト接合部分には、締結具51を取付けるためのボルト孔52(またはリベット穴)が設けられる。ボルト接合については後述する。 ボ ル ト Bolt joining is mainly joining (or rivet joining) using fasteners 51 such as bolts and nuts. Bolt holes 52 (or rivet holes) for attaching the fasteners 51 are provided in the bolt joint portions. The bolt joint will be described later.
 図1の実施例では、第1の構造材1の右側の側部(A側)に第1の突出部32が一体に設けられ、第2の構造材2の左側の側部(B側)に第2の突出部42が一体に設けられた場合を示している。但し、第1の構造材1の左側の側部(B側)に第1の突出部32を取付け、第2の構造材2の右側の側部(A側)に第2の突出部42を取付けるようにしてもよい。 In the embodiment of FIG. 1, a first protrusion 32 is integrally provided on the right side (A side) of the first structural member 1, and the left side (B side) of the second structural member 2. The case where the 2nd protrusion part 42 is integrally provided is shown. However, the 1st protrusion part 32 is attached to the left side part (B side) of the 1st structural material 1, and the 2nd protrusion part 42 is attached to the right side part (A side) of the 2nd structural material 2. You may make it attach.
 (2)この際、各突出部32,42と相手方の構造材2,1の側部との間のボルト接合は、少なくとも、各突出部32,42の互いに離れた2箇所の先端部の位置で行うようにするのが好ましい。 (2) At this time, at least the positions of the two distal end portions of the projecting portions 32 and 42 that are separated from each other are bolted between the projecting portions 32 and 42 and the side portions of the other structural members 2 and 1. It is preferable to carry out at.
 ここで、一方の突出部32の先端部(におけるボルト接合部分)と、他方の突出部42の先端部(におけるボルト接合部分)とは、構造材1,2の長手方向55に対して接続強度が得られる所要の距離e(先端部間の離隔距離:図3参照)だけ離間させるようにする。 Here, the distal end portion (the bolt joint portion) of one projecting portion 32 and the distal end portion (the bolt joint portion) of the other projecting portion 42 are connected to each other in the longitudinal direction 55 of the structural members 1 and 2. Is separated by a required distance e (a separation distance between the tip portions: see FIG. 3).
 そして、一方の突出部32の先端部に対するボルト接合部分、および、他方の突出部42の先端部に対するボルト接合部分(即ち、離間した2箇所のボルト接合部分)は、構造材1,2の長手方向55と直交する方向(図3の上下方向)については、それぞれ単数または複数設けることができる。例えば、図3のように上下部と中央部の3箇所(左右合計6箇所)の位置に設けてもよいし、図5Aの例のように上下方向の中央部の1箇所(左右合計2箇所)の位置のみに設けてもよいし、図5Bの例のように上下部の2箇所(左右合計4箇所)の位置に設けてもよい。または、図6A(~図6C)の例のように上下方向の4箇所以上(例えば、片側7箇所)の位置に設けてもよい。 And the bolt joint part with respect to the front-end | tip part of the one protrusion part 32, and the bolt joint part (namely, two bolt joint parts spaced apart) with respect to the front-end | tip part of the other protrusion part 42 are the longitudinal directions of the structural materials 1 and 2. About the direction (up-down direction of FIG. 3) orthogonal to the direction 55, one or more can each be provided. For example, as shown in FIG. 3, it may be provided at three positions (upper left and right total of six places) of the upper and lower parts and the central part, or as shown in FIG. ) May be provided only at the position of 2), or may be provided at two positions in the upper and lower parts (four places on the left and right in total) as in the example of FIG. Alternatively, as in the example of FIG. 6A (to FIG. 6C), it may be provided at four or more positions in the vertical direction (for example, seven positions on one side).
 更に、上記したような離間した2箇所のボルト接合部分を有していれば、ボルト接合部分は更に増やすことができる。例えば、構造材2,1の長手方向55と直交する方向に対してスペース上の限度いっぱいまでボルト接合部分を設けている場合には、更に、図5Cに示すように、構造材2,1の長手方向55に沿って追加のボルト接合部分を設けてもよい。例えば、図5Cでは、図3のものに対し、構造材1,2の上下の縁部に沿って(U字状となるように)ボルト接合部分を上下に1箇所ずつ追加している(図6Aも同様)。 Furthermore, if there are two spaced bolt joint portions as described above, the bolt joint portions can be further increased. For example, in the case where the bolt joint portion is provided up to the limit on the space with respect to the direction orthogonal to the longitudinal direction 55 of the structural materials 2 and 1, as shown in FIG. Additional bolt joints may be provided along the longitudinal direction 55. For example, in FIG. 5C, bolt joints are added one by one along the top and bottom edges of the structural materials 1 and 2 (to be U-shaped) in FIG. The same applies to 6A).
 (3)具体的には、突出部32,42が、構造材1,2の端部1a,2aにおける片側の側部(A側またはB側)に基部31,41を固定され、先端側部分が構造材1,2の端部1a,2aから長手方向55へ突出された接続部材3,4によって構成されるようにしてもよい。
 そして、2本の構造材1,2が、端部1a,2aどうしを向かい合わせにして近接配置される。
 更に、各突出部32,42が互いに反対側に位置するように相手方の構造材2,1の端部2a,1aの側部(A側またはB側)に重ねられた状態で、2本の構造材1,2が、直線状に接続されるようにしてもよい。
(3) Specifically, the protrusions 32 and 42 have the base portions 31 and 41 fixed to one side (A side or B side) of the end portions 1a and 2a of the structural members 1 and 2, respectively. May be constituted by connecting members 3 and 4 projecting in the longitudinal direction 55 from the end portions 1a and 2a of the structural members 1 and 2.
Then, the two structural members 1 and 2 are arranged close to each other with the end portions 1a and 2a facing each other.
Further, in a state where the projecting portions 32 and 42 are stacked on the side portions (A side or B side) of the end portions 2a and 1a of the other structural member 2 and 1 so as to be located on the opposite sides, The structural materials 1 and 2 may be connected in a straight line.
 ここで、接続部材3,4は、長手方向55のほぼ半部を基部31,41として構造材1,2に固定すると共に、残りのほぼ半部(先端側部分)を、突出部32,42とするのが好ましい。このようにすることにより、構造材1,2の端部1a,2aをほぼ突き合わせ状態にした時に、図2の縦断面図に示すように、接続部材3,4の基部31,41と、構造材1,2の側部と相手側の接続部材4,3の突出部42,32とを3重に重ねて通しボルトで一度にボルト接合(共締め)することが可能となる(3重接合)。これにより、接続部材3,4の基部31,41と、構造材1,2の側部とがボルト接合される。 Here, the connection members 3 and 4 are fixed to the structural materials 1 and 2 with the substantially half portions in the longitudinal direction 55 as the base portions 31 and 41, and the remaining substantially half portions (tip side portions) are protruded portions 32 and 42. Is preferable. In this way, when the end portions 1a and 2a of the structural members 1 and 2 are brought into a substantially abutted state, the base portions 31 and 41 of the connection members 3 and 4 and the structure as shown in the longitudinal sectional view of FIG. The side portions of the members 1 and 2 and the projecting portions 42 and 32 of the mating connecting members 4 and 3 are overlapped in a triple manner and can be bolted together (jointly) with a through bolt (triple joining). ). Thereby, the base parts 31 and 41 of the connection members 3 and 4 and the side part of the structural materials 1 and 2 are bolt-joined.
 これに対し、構造的には、例えば、図7A(~図7C)に示すように、基部31,41を接続部材3,4の半分よりも小さくすることが可能である。このようにした場合、構造材1,2の側部と相手側の接続部材4,3の突出部42,32とが2重に重なった状態でのボルト接合となる(2重接合)。そのため、接続部材3,4の基部31,41と、構造材1,2の側部との間はボルト接合(共締め)されないので、剪断接合のために、例えば、後述するような溶接部75a~75cなどが必要になる。更に必要に応じて、栓溶接やスポット溶接などの溶接部75dを設けたりしてもよい。 On the other hand, structurally, for example, as shown in FIG. 7A (to FIG. 7C), the base portions 31 and 41 can be made smaller than half of the connection members 3 and 4. In this case, the bolts are joined in a state where the side portions of the structural members 1 and 2 and the projecting portions 42 and 32 of the mating connecting members 4 and 3 are overlapped (double joining). Therefore, since the base portions 31 and 41 of the connection members 3 and 4 and the side portions of the structural members 1 and 2 are not bolted (jointly fastened), for shear joining, for example, a welded portion 75a as described later is used. ~ 75c is required. Furthermore, if necessary, a welded portion 75d such as plug welding or spot welding may be provided.
 なお、上記したような2本の構造材1,2による直線状の接続は、梁と梁との間の接続や、柱と柱との間の接続などに利用することができる。 In addition, the linear connection by the two structural materials 1 and 2 as described above can be used for a connection between beams and a connection between columns.
 端部1a,2aどうしを向かい合わせにして近接配置とは、構造材1,2の端部1a,2aどうしを、芯をズラすことなくほぼ突き合わせにした状態のことである。 The close arrangement with the end portions 1a and 2a facing each other means a state in which the end portions 1a and 2a of the structural materials 1 and 2 are almost abutted without shifting the core.
 2本の構造材1,2の端部1a,2a間は、溶接部75cを設けるなどのために長手方向55の隙間s(図3参照)を設けることとなるが、所要の接続強度を確保するためには、隙間sは可能な限り小さくするのが好ましい。よって、この隙間sは、溶接部75cの大きさに、精度誤差による逃げ代を加えた程度にするとよい。 A gap s (see FIG. 3) in the longitudinal direction 55 is provided between the end portions 1a and 2a of the two structural members 1 and 2 in order to provide a welded portion 75c, but the required connection strength is ensured. In order to do so, the gap s is preferably as small as possible. Therefore, the gap s may be set to a size obtained by adding a clearance due to an accuracy error to the size of the welded portion 75c.
 (4)図2に示すように、突出部32,42(または、接続部材3,4)は、構造材1,2よりも断面が小さいものとするのが好ましい。 (4) As shown in FIG. 2, the protrusions 32 and 42 (or connection members 3 and 4) preferably have a smaller cross section than the structural materials 1 and 2.
 ここで、突出部32,42は、構造材1,2のほぼ半分程度にまで断面を小さくしても、構造材1,2どうしの接続強度を確保することが可能である。 Here, even if the protrusions 32 and 42 have a cross-section that is almost half that of the structural materials 1 and 2, the connection strength between the structural materials 1 and 2 can be secured.
 (5)更に、図3(~図7C)に示すように、突出部32,42(または、接続部材3,4)は、構造材1,2の側部に対し溶接接合によって一体に固定されるようにしてもよい(例えば、溶接部75a~75dなど)。 (5) Furthermore, as shown in FIG. 3 (to FIG. 7C), the protrusions 32 and 42 (or connection members 3 and 4) are integrally fixed to the side portions of the structural materials 1 and 2 by welding. You may make it (for example, the welding parts 75a-75d etc.).
 ここで、溶接部75a~75dは、構造材1,2と接続部材3,4の基部31,41とを隅肉溶接や栓溶接やスポット溶接などで溶接したものとすることができる。具体的な溶接については後述する。 Here, the welded portions 75a to 75d can be formed by welding the structural materials 1 and 2 and the base portions 31 and 41 of the connecting members 3 and 4 by fillet welding, plug welding, spot welding, or the like. Specific welding will be described later.
 なお、構造材1,2や突出部32,42(または、接続部材3,4)は、それぞれ、例えば、平板状のものや角筒状のものなどとすることができるが、好ましくは、以下のようにする。 The structural members 1 and 2 and the projecting portions 32 and 42 (or connection members 3 and 4) can be, for example, flat plates or rectangular tubes, but preferably Like this.
 (6)図2に示すように、構造材1,2は、ウェブ部61の両側縁部に面直方向の両側へ張出す一対のフランジ部62(両フランジ)を有するH形鋼とするのが好ましい。
 また、突出部32,42(または、接続部材3,4)は、ウェブ部65の両側縁部に面直方向の片側へ張出す一対のフランジ部66(片フランジ)を有する(C字断面の)軽溝形鋼などとするのが好ましい。
 そして、突出部32,42(または、接続部材3,4)は、構造材1,2の側部(A側またはB側)内に収容可能とするのが好ましい。
(6) As shown in FIG. 2, the structural members 1 and 2 are H-shaped steels having a pair of flange portions 62 (both flanges) projecting to both sides in the perpendicular direction on both side edges of the web portion 61. Is preferred.
The protrusions 32 and 42 (or the connection members 3 and 4) have a pair of flange portions 66 (single flanges) projecting to one side in the direction perpendicular to the side edges of the web portion 65 (of the C-shaped cross section). ) It is preferable to use light groove steel.
And it is preferable that the protrusion parts 32 and 42 (or connection member 3 and 4) can be accommodated in the side part (A side or B side) of the structural materials 1 and 2. FIG.
 ここで、H形鋼とされた2本の構造材1,2は、少なくとも、フランジ部62の外表面どうしが互いに面一に連なった状態で接続されるものとなる。水平方向へ延びる構造材1,2や接続部材3,4の場合、ウェブ部61,65は、上下方向へ向いた面となり、ウェブ部61,65の両側縁部は、上下の縁部となる。また、フランジ部62,66は、水平方向へ延びる面となる。そして、このような構造材1,2を接続すると、構造材1,2の上下面(フランジ部62の外表面)が平坦に連なった面となる。 Here, the two structural members 1 and 2 that are H-shaped steels are connected in a state where at least the outer surfaces of the flange portion 62 are flush with each other. In the case of the structural members 1 and 2 and the connecting members 3 and 4 extending in the horizontal direction, the web portions 61 and 65 are surfaces that face in the vertical direction, and both side edges of the web portions 61 and 65 are vertical edges. . Moreover, the flange parts 62 and 66 become a surface extended in a horizontal direction. When such structural members 1 and 2 are connected, the upper and lower surfaces of the structural members 1 and 2 (the outer surface of the flange portion 62) become flat surfaces.
 そして、接続部材3,4は、H形鋼とされた構造材1,2の両側にできる凹状空間の内部に収容可能な大きさとされる。接続部材3,4は、H形鋼とされた構造材1,2の両側の凹状空間の内部と同じかそれよりも小さいものとされる。なお、接続部材3,4については軽溝形鋼にしなくても、H形鋼とされた構造材1,2の側部内へ収容することは可能である。 The connecting members 3 and 4 are sized so as to be accommodated in the concave spaces formed on both sides of the structural members 1 and 2 made of H-shaped steel. The connecting members 3 and 4 are the same as or smaller than the insides of the concave spaces on both sides of the structural members 1 and 2 made of H-shaped steel. The connecting members 3 and 4 can be accommodated in the side portions of the structural members 1 and 2 that are H-shaped steels without using light-grooved steel.
 そして、構造材1,2をH形鋼とし、接続部材3,4を軽溝形鋼などとした場合、上記した接続部材3,4の基部31,41と構造材1,2の側部(A側またはB側)との間の隅肉溶接などによる溶接部75a~75cは、以下のようなものとなる。 When the structural members 1 and 2 are H-shaped steels and the connecting members 3 and 4 are light groove shaped steels, the base portions 31 and 41 of the connecting members 3 and 4 and the side portions of the structural members 1 and 2 ( The welds 75a to 75c by fillet welding between the A side and the B side) are as follows.
 即ち、図3に示すように、先ず、フランジ部62,66どうしを縁部に沿って長手方向55に溶接した第一の溶接部75aが設けられる。次に、必要に応じて、ウェブ部61,65どうしをウェブ部65の縁部に沿って(ウェブ部61,65の)幅方向(図中上下方向)に溶接した第ニの溶接部75bを設けるようにする。更に必要な場合には、フランジ部62,66どうしをフランジ部66の端縁部に沿って(フランジ部62,66の)幅方向(紙面と垂直な方向)に溶接した第三の溶接部75cを設けるようにする。 That is, as shown in FIG. 3, first, a first welded portion 75a is provided in which the flange portions 62 and 66 are welded in the longitudinal direction 55 along the edge portion. Next, if necessary, a second welded portion 75b in which the web portions 61 and 65 are welded to each other along the edge of the web portion 65 (in the web portions 61 and 65) in the width direction (vertical direction in the figure). Try to provide it. Further, if necessary, a third welded portion 75c in which the flange portions 62 and 66 are welded along the edge portion of the flange portion 66 (the flange portions 62 and 66) in the width direction (direction perpendicular to the paper surface). To be provided.
 第一の溶接部75aおよび第三の溶接部75cは、主にモーメントの伝達に有効である。また、第ニの溶接部75bもモーメントの伝達に利用することができる。そして、上記した接続部材3,4の基部31,41と、構造材1,2のウェブ部61と相手側の接続部材4,3の突出部42,32とを3重に重ねて通しボルトで一度にボルト接合(共締め)する場合、ボルト接合によって剪断力を伝達することになる。なお、第一の溶接部75a、第ニの溶接部75b、第三の溶接部75cについては、強度上の優先順位を有しており、第一の溶接部75aは必須であるが、第ニの溶接部75b、第三の溶接部75cは、必要に応じて設ければよい。 The first welded portion 75a and the third welded portion 75c are mainly effective for transmitting moments. The second weld 75b can also be used for moment transmission. Then, the base portions 31 and 41 of the connecting members 3 and 4 described above, the web portion 61 of the structural members 1 and 2 and the protruding portions 42 and 32 of the mating connecting members 4 and 3 are overlapped with a through bolt. When bolt joining (co-fastening) at once, shearing force is transmitted by bolt joining. The first welded portion 75a, the second welded portion 75b, and the third welded portion 75c have priority in strength, and the first welded portion 75a is essential, but the second welded portion 75a is essential. The welded portion 75b and the third welded portion 75c may be provided as necessary.
 また、図7A(~図7C)のように構造材1,2のウェブ部61と相手側の接続部材4,3の突出部42,32とを2重に重ねてボルト接合する場合、更に必要に応じて上記したような栓溶接やスポット溶接などによる溶接部75dを施すようにする。なお、栓溶接やスポット溶接などの溶接部75dは、隅肉溶接などによる溶接部75a~75cに替えて行うようにすることも可能である。 Further, as shown in FIG. 7A (to FIG. 7C), it is further necessary when the web portion 61 of the structural members 1 and 2 and the protruding portions 42 and 32 of the mating connecting members 4 and 3 are overlapped and bolted. In accordance with the above, the welded portion 75d by plug welding or spot welding as described above is applied. The welded portion 75d such as plug welding or spot welding can be replaced with welded portions 75a to 75c by fillet welding or the like.
 なお、溶接接合による溶接部75a~75cを、接続部材3,4の基部31,41におけるウェブ部65の縁部やフランジ部66の縁部などに沿った隅肉溶接部などとする場合、隅肉溶接は、ウェブ部65の縁部とウェブ部61との間に生じるウェブ部65の板厚分程度の段差や、フランジ部66の縁部とフランジ部62との間に生じるフランジ部66の板厚分程度の段差などを利用して行うようにするのが好ましい。この際、接続部材3,4のフランジ部66は、隅肉溶接のビードが構造材1,2の凹状空間から外へはみ出さないように、少なくとも、ビードの幅程度分以上に構造材1,2のフランジ部62よりも短くするのが好ましい。このように隅肉溶接の溶接部75a~75cを、ウェブ部65やフランジ部66の板厚と等しくなるようにすることにより、溶接部75a~75cを最大化すると共に、フランジ部62に対するフランジ部66の引き寸法も短くすることができるので、構造的に有利である。また、部分溶け込み溶接などを行う場合には、ウェブ部61,65の縁部間や、フランジ部62,66の縁部間などに開先を加工して行うようにする。 In the case where the welded portions 75a to 75c by welding are used as fillet welded portions along the edges of the web portions 65 and the flange portions 66 of the base portions 31 and 41 of the connecting members 3 and 4, corners or the like are used. The wall welding is performed between the edge portion of the web portion 65 and the web portion 61, a level difference corresponding to the plate thickness of the web portion 65, or between the edge portion of the flange portion 66 and the flange portion 62. It is preferable to carry out using a level difference of about the plate thickness. At this time, the flange portions 66 of the connection members 3 and 4 have at least the width of the structural material 1 or more so that the fillet weld bead does not protrude from the concave space of the structural materials 1 and 2. It is preferable to make it shorter than the second flange portion 62. In this way, the welded portions 75a to 75c of the fillet weld are made equal to the plate thickness of the web portion 65 and the flange portion 66, thereby maximizing the welded portions 75a to 75c and the flange portion with respect to the flange portion 62. The pulling dimension of 66 can also be shortened, which is structurally advantageous. Further, when performing partial penetration welding or the like, the groove is processed between the edge portions of the web portions 61 and 65 or between the edge portions of the flange portions 62 and 66.
 (7)ボルト接合には、(締結具51として)高力ボルト77(またはリベット)を用いるようにしてもよい。
 そして、高力ボルト77(またはリベット)は、少なくとも、構造材1,2の側部(A側またはB側)内で、構造材1,2のウェブ部61と、相手方の突出部42,32の先端部との間を、ウェブ部61の面直方向に貫通するように設置してもよい。
 または、高力ボルト77(またはリベット)は、構造材1,2の側部(A側またはB側)内で、構造材1,2のウェブ部61と、突出部32,42(または、接続部材3,4)の基部31,41と、相手方の突出部42,32の先端部との間を、ウェブ部61の面直方向に貫通するように設置してもよい。
(7) A high-strength bolt 77 (or rivet) may be used for the bolt connection (as the fastener 51).
The high-strength bolt 77 (or rivet) includes at least the web portion 61 of the structural materials 1 and 2 and the projecting portions 42 and 32 of the counterparts in the side portions (A side or B side) of the structural materials 1 and 2. You may install so that it may penetrate between the front-end | tip parts of the web part 61 in the surface orthogonal | vertical direction.
Alternatively, the high-strength bolt 77 (or rivet) is connected to the web portion 61 of the structural materials 1 and 2 and the protruding portions 32 and 42 (or connection) in the side portions (A side or B side) of the structural materials 1 and 2. You may install so that the base part 31 and 41 of the members 3 and 4) and the front-end | tip part of the other protrusion part 42 and 32 may penetrate in the surface perpendicular direction of the web part 61. FIG.
 ここで、高力ボルト77は、高い強度を持って高い引張力に耐えることができると共に、締付力を均一にできるように製造された締結具51のことである。また、リベットも高力ボルト77と同様の目的で使用することができる。高力ボルト77やリベットを用いることで、フランジ部62,66どうしの間については、強度的に締結具51による締結を行う必要をなくすことが可能となる。 Here, the high-strength bolt 77 is a fastener 51 manufactured so as to be able to withstand a high tensile force with a high strength and to have a uniform clamping force. The rivet can also be used for the same purpose as the high strength bolt 77. By using the high-strength bolts 77 and rivets, it is possible to eliminate the need for fastening with the fasteners 51 between the flange portions 62 and 66 in terms of strength.
 また、高力ボルト77やリベットを用いることにより、ウェブ部61,65どうしのボルト接合部分についても、通常のボルトを用いる場合よりも締結具51の使用本数を減らすことが期待できる。 Also, by using high strength bolts 77 and rivets, the number of fasteners 51 to be used can be expected to be reduced at the bolt joint portions between the web portions 61 and 65 as compared with the case of using normal bolts.
 例えば、図3では、接続部材3,4の各ウェブ部65に対して片側3本ずつ、合計6本の高力ボルト77など(以下、「高力ボルト77など」にはリベットも含まれるものとする)を用いるようにしているが、例えば、図5Aに示すように、片側1本ずつ、合計2本の高力ボルト77などを用いるようにしたり、図5Bに示すように、片側2本ずつ、合計4本の高力ボルト77などを用いるようにしたりすることで、高力ボルト77などの使用本数を減らすようにしてもよい。 For example, in FIG. 3, a total of six high-strength bolts 77 and the like (hereinafter referred to as “high-strength bolts 77 and the like”) include rivets, three on each side of the web portions 65 of the connecting members 3 and 4. For example, as shown in FIG. 5A, a total of two high-strength bolts 77 or the like may be used on each side, as shown in FIG. 5A, or as shown in FIG. 5B. The number of high strength bolts 77 and the like may be reduced by using a total of four high strength bolts 77 and the like.
 この際、高力ボルト77などは、大径化することによって使用本数を減らすことができる。即ち、小径の高力ボルト77などを多数使用しているものを、大径の高力ボルト77などを使用することでボルト接合部分の箇所を少なくできる。なお、各場合で使用する高力ボルト77などは、1種類の大きさで統一するのが好ましい。 At this time, the number of high-strength bolts 77 and the like can be reduced by increasing the diameter. That is, by using a large-diameter high-strength bolt 77 or the like that uses a large number of small-diameter high-strength bolts 77 or the like, the number of bolt joint portions can be reduced. In addition, it is preferable to unify the high strength bolts 77 and the like used in each case with one kind of size.
 そして、例えば、図3や図5Bなどに示すように、各側について高力ボルト77などを複数化する場合には、高力ボルト77などは、ウェブ部61,65の幅方向(図中、上下方向)に対しできるだけ大きく離して設置するのが好ましい。このように、高力ボルト77などの間の(図中上下方向に対する)間隔を大きくすることで、接合部に発生するモーメントMb(図10B参照)に対してより大きな耐力を得ることが可能になる。 For example, as shown in FIGS. 3 and 5B, when a plurality of high-strength bolts 77 are formed on each side, the high-strength bolts 77 are arranged in the width direction of the web portions 61 and 65 (in the drawing, It is preferable to install as far as possible from the vertical direction. Thus, by increasing the distance between the high-strength bolts 77 and the like (relative to the vertical direction in the figure), it is possible to obtain a greater proof stress against the moment Mb (see FIG. 10B) generated at the joint. Become.
 ちなみに、構造材1,2に作用するモーメントF1や剪断力F2に有効なのは、突出部32,42の先端部間(接合部間)の離隔距離(距離e)を広く取ることであり、高力ボルト77などの締結具51は、接合部間の剪断力Qbと、接合部のモーメントMbに対抗できるものにする必要がある。そして、高力ボルト77などをウェブ部61,65の幅方向(図中、上下方向)に対し大きく離して設置することで接合部のモーメントMbに対抗する偶力を大きく取ることができる。そして、上下方向または縦並びの高力ボルト77などの配置だけでは偶力が不足する場合に、図5Cや図6Aなどに示すように、ウェブ部61,65の上下の位置に沿って高力ボルト77などを追加することで、偶力を補強することができる。また、上下方向または縦並びの高力ボルト77などの本数によって、接合部間の剪断力Qbに対抗することができる。 Incidentally, what is effective for the moment F1 and the shearing force F2 acting on the structural materials 1 and 2 is to take a wide separation distance (distance e) between the tip portions (between the joint portions) of the projecting portions 32 and 42. The fastener 51 such as the bolt 77 needs to be able to counter the shearing force Qb between the joints and the moment Mb of the joints. And the high strength bolt 77 etc. can be taken largely with respect to the width direction (up-down direction in the figure) of the web parts 61 and 65, and the couple which opposes the moment Mb of a junction part can be taken large. Then, when the couple is insufficient only by the arrangement of the high-strength bolts 77 in the vertical direction or vertically, as shown in FIGS. 5C and 6A, the high-strength along the vertical positions of the web portions 61 and 65. The couple can be reinforced by adding bolts 77 and the like. Further, the number of the high-strength bolts 77 arranged in the vertical direction or vertically can counter the shearing force Qb between the joints.
 (8)H形鋼とされた構造材1,2のウェブ部61の側部(A側またはB側)に対し、軽溝形鋼などとされた接続部材3,4は、ウェブ部61,65どうしおよびフランジ部62,66どうしがそれぞれ面接触するように嵌め込まれる(または差し込まれる)ようにしてもよい。 (8) With respect to the side portion (A side or B side) of the web portion 61 of the structural materials 1 and 2 that are H-shaped steel, the connecting members 3 and 4 that are light groove shaped steel are the web portion 61, 65 and the flange portions 62 and 66 may be fitted (or inserted) so as to be in surface contact with each other.
 ここで、軽溝形鋼などとされた接続部材3,4は、H形鋼とされた構造材1,2の両側部の凹状空間の内部とほぼ等しい(または若干小さい)大きさおよび形状とされる。このようにすることで、寸法誤差に対する逃げ代を確保しつつ、H形鋼とされた構造材1,2のウェブ部61の側部(A側またはB側)に対して、軽溝形鋼などとされた接続部材3,4の突出部32,42を差し込むようにして嵌合することが可能となる。そして、この嵌合により、接続部材3,4の外形面と、構造材1,2の側部における凹状空間の内形面との間のウェブ部61,65どうしをはじめ、ほぼ全体が接触部となり、構造材1,2どうしの接続精度のよいガイド機能になる。なお、このウェブ部61,65どうしの接触面は、特に、高力ボルト77を用いた3重接合の場合に、構造材1,2のウェブ部61の面と接続部材3,4の基部31,41および突出部32,42のボルト締め付け面に摩擦力が発生する摩擦面となる(なお、リベット接合など支圧接合の場合は、このような摩擦面は不要となる)。 Here, the connecting members 3 and 4 made of light grooved steel and the like have a size and shape substantially equal (or slightly smaller) to the inside of the concave spaces on both sides of the structural members 1 and 2 made of H-shaped steel. Is done. By doing in this way, light groove shape steel with respect to the side part (A side or B side) of the web part 61 of the structural materials 1 and 2 made into H shape steel, ensuring the allowance for a dimensional error. It is possible to fit the projections 32 and 42 of the connecting members 3 and 4 that are made into the above-described manner. And by this fitting, almost all the contact portions including the web portions 61 and 65 between the outer shape surfaces of the connection members 3 and 4 and the inner shape surfaces of the concave spaces in the side portions of the structural materials 1 and 2 are contacted. Thus, a guide function with good connection accuracy between the structural members 1 and 2 is obtained. Note that the contact surfaces of the web portions 61 and 65 are the surface of the web portion 61 of the structural members 1 and 2 and the base portion 31 of the connecting members 3 and 4, particularly in the case of triple joining using the high strength bolt 77. , 41 and the bolt tightening surfaces of the projecting portions 32, 42 are friction surfaces that generate a frictional force (in the case of pressure bearing bonding such as rivet bonding, such a friction surface is unnecessary).
 なお、H形鋼とされた構造材1,2のウェブ部61の側部(A側またはB側)に対して、軽溝形鋼などとされた接続部材3,4の突出部32,42を差し込み易くするために、突出部32,42の角部などには、適宜、呼び込み用のアール部などを設けるようにしてもよい。 In addition, with respect to the side part (A side or B side) of the web part 61 of the structural materials 1 and 2 made into H shape steel, the protrusion parts 32 and 42 of the connection members 3 and 4 made into light groove shape steel etc. In order to facilitate the insertion, a rounded portion or the like for calling may be provided at the corners of the projecting portions 32 and 42 as appropriate.
 (9)そして、構造材1,2を上記した継手構造で接続して建築用構造体を構築するようにしてもよい。
 ここで、上記した継手構造は、少なくとも1箇所以上備えていればよい。建築用構造体は、建築物の骨組となるものである。
(9) The structural members 1 and 2 may be connected by the joint structure described above to construct a building structure.
Here, the above-described joint structure may have at least one place. The building structure is a framework of the building.
 <作用>この実施例の作用は、以下の通りである。 <Operation> The operation of this embodiment is as follows.
 この実施例の継手構造は、図8Aに示すように、2本の棒81,82を、先端部を長手方向に重複させた状態で、互いに距離eだけ離れた2箇所の先端部の位置を接合して(接合部83,84)、曲げモーメントF1と剪断力F2を相互に伝達させるようにした繋ぎ方と、基本的に同じ接続構造を有することができるようになっている。 In the joint structure of this embodiment, as shown in FIG. 8A, two rods 81 and 82 are located at the positions of two tip portions separated from each other by a distance e in a state where the tip portions overlap in the longitudinal direction. It is possible to have a connection structure that is basically the same as the connection method in which the bending moment F1 and the shearing force F2 are transmitted to each other by joining (joining portions 83 and 84).
 そして、この2本の棒81,82に単純曲げを与えた時に2本の棒81,82に発生する曲げモーメントは、図8Bのモーメント図に示すようなものとなる。この図によれば、繋いだ棒81,82の両端部を下から支持して2本の棒81,82の中間部に上から力Pを加え、接合部83,84にモーメントが発生しないピン接合と仮定すると、図のような曲げモーメントが発生する。この際、2箇所の接合部83,84間の距離eの区間では、各棒81,82に発生する曲げモーメントが先端側へ向けて徐々に小さくなって行き、距離eの区間の中央部では、曲げモーメントが半分になる。そのため、上記距離eの区間では、棒81,82の断面を徐々に小さくして行っても必要な接続強度が確保できることになる。または、上記距離eの区間の中央部から先で、棒81,82の断面を半分にしても必要な接続強度が確保できることになる。 The bending moment generated in the two bars 81 and 82 when simple bending is applied to the two bars 81 and 82 is as shown in the moment diagram of FIG. 8B. According to this figure, both ends of the connected rods 81 and 82 are supported from below, a force P is applied from above to the intermediate portion of the two rods 81 and 82, and no moment is generated at the joints 83 and 84. Assuming joining, a bending moment as shown in the figure occurs. At this time, in the section of the distance e between the two joint portions 83 and 84, the bending moment generated in each rod 81 and 82 gradually decreases toward the tip side, and in the center of the section of the distance e. The bending moment is halved. Therefore, in the section of the distance e, necessary connection strength can be ensured even if the cross sections of the bars 81 and 82 are gradually reduced. Alternatively, the necessary connection strength can be ensured even if the cross sections of the bars 81 and 82 are halved from the center of the section of the distance e.
 そこで、図9に示すように、上記した2本の棒81,82の繋ぎ方を構造材1,2どうしの接続部にうまく適用するために、先ず、上記距離eの区間の中央部で構造材1,2の端部1a,2aどうしをほぼ突き合わせに近い状態に配置する。そして、構造材1,2の端部1a,2aの片側の側面から断面の小さい突出部32,42を延ばして、突出部32,42の互いに離れた2箇所の先端部の位置でボルト接合する構造にする。このように、2本の棒81,82の繋ぎ方を単純に構造材1,2の接続に適用すると図1(~図4)の例になる。 Therefore, as shown in FIG. 9, in order to successfully apply the above-described method of connecting the two rods 81 and 82 to the connecting portion between the structural members 1 and 2, first, the structure is formed at the center of the section of the distance e. The end portions 1a and 2a of the materials 1 and 2 are arranged so as to be almost close to each other. And the protrusion parts 32 and 42 with a small cross section are extended from the one side surface of the edge parts 1a and 2a of the structural materials 1 and 2, and it bolts in the position of the two front-end | tip parts of the protrusion parts 32 and 42 mutually separated. Make the structure. As described above, when the method of connecting the two bars 81 and 82 is simply applied to the connection of the structural members 1 and 2, the example shown in FIG. 1 (FIG. 4) is obtained.
 この際、構造材1,2の端部1a,2aどうしの間には、隙間sを設けてもよいことになる。但し、この隙間sは、上記したように、できるだけ小さくするのが好ましい。 At this time, a gap s may be provided between the end portions 1a and 2a of the structural materials 1 and 2. However, the gap s is preferably as small as possible as described above.
 更に、図3や図5Bに示すように、突出部32,42の互いに離れた2箇所の先端部における締結具51(高力ボルト77)の使用本数を複数化して図中上下方向に間隔を大きくする。すると、図10A(図10B)に示すように、複数本の締結具51によって接合部83,84に発生するモーメントMbの伝達ができるようになるため、図に距離eで示す区間に発生する破線mで示す曲げモーメントF1の勾配が実線nで示すように小さくなって、剪断力Qbが低下するので、突出部32,42にかかる剪断力を小さくすることができ、構造的に有利となる。 Further, as shown in FIG. 3 and FIG. 5B, the number of fasteners 51 (high strength bolts 77) used at the two distal ends of the projecting portions 32 and 42 are pluralized, and the intervals in the vertical direction in the figure are increased. Enlarge. Then, as shown in FIG. 10A (FIG. 10B), the moment Mb generated in the joints 83 and 84 can be transmitted by the plurality of fasteners 51, and therefore a broken line generated in the section indicated by the distance e in the figure. Since the gradient of the bending moment F1 indicated by m becomes smaller as indicated by the solid line n and the shearing force Qb decreases, the shearing force applied to the protrusions 32 and 42 can be reduced, which is structurally advantageous.
 <効果>この実施例によれば、以下のような効果を得ることができる。 <Effect> According to this embodiment, the following effects can be obtained.
 (効果1)各構造材1,2が、片側の側部(A側またはB側)から突出する突出部32,42を一体に有するものとした。
 また、2本の構造材1,2が互いに近接され、各突出部32,42が互いに反対側に位置するように相手方の構造材2,1の側部(A側またはB側)に重ね合わされるように配置した。
 そして、各突出部32,42と相手方の構造材2,1の側部(A側またはB側)との間が、それぞれボルト接合によって固定されるようにした。
(Effect 1) Each structural material 1 and 2 shall have integrally the protrusion parts 32 and 42 which protrude from the one side part (A side or B side).
In addition, the two structural members 1 and 2 are brought close to each other, and are superposed on the side portions (A side or B side) of the other structural member 2 and 1 so that the projecting portions 32 and 42 are located on the opposite sides. Arranged so that.
And between each protrusion part 32 and 42 and the side part (A side or B side) of the other structural material 2 and 1, it was made to fix by bolt joining, respectively.
 これにより、構造材1,2に予め突出部32,42(2枚の接続部材3,4)を設けておくだけで、2本の構造材1,2を直接的に接続することが可能となる。よって、図11の比較例のように、構造材100,200の接続に、構造材100,200とは別体の添え板300を多数枚(図9では8枚)用いる必要をなくすことができる。その結果、全体として少ない接続部材3,4や少ない締結具51で構造材1,2の接続を確実に行うことができるようになり、その分、部品コストの削減や施工時間の短縮を図ることができる。 As a result, it is possible to directly connect the two structural members 1 and 2 simply by providing the structural members 1 and 2 with the protrusions 32 and 42 (two connecting members 3 and 4) in advance. Become. Therefore, as in the comparative example of FIG. 11, it is possible to eliminate the need to use a large number of attachment plates 300 (eight in FIG. 9) separate from the structural materials 100 and 200 for connecting the structural materials 100 and 200. . As a result, it is possible to reliably connect the structural materials 1 and 2 with a small number of connecting members 3 and 4 and a small number of fasteners 51 as a whole, thereby reducing the part cost and the construction time.

 この際、構造材1,2の片側の側部(A側またはB側)に対して突出部32,42(接続部材3,4)を予め一体に固定する構造を採用することで、芯ズレや段差のない状態で構造材1,2を接続することが可能になる。 At this time, by adopting a structure in which the projecting portions 32 and 42 (connecting members 3 and 4) are integrally fixed in advance to one side portion (A side or B side) of the structural materials 1 and 2, the core misalignment is adopted. It is possible to connect the structural materials 1 and 2 without any step.
 また、構造材1,2に予め突出部32,42(接続部材3,4)取付けておくことで、構造材1,2と接続部材3,4とが一部品化されるので、現場で図11のような添え板300を取り扱う必要がなくなり、現場での施工を容易化して、施工時間の短縮を図ることができる。更に、構造材1,2の側部(A側またはB側)に接続部材3,4を突出状態で取付けておくだけのシンプルな構造であるため、構造材1,2の端部1a,2aを加工したり特別な形状にしたりする必要がなく、現場などでの加工の手間などもかからない。 Further, by attaching the protrusions 32 and 42 (connection members 3 and 4) to the structural materials 1 and 2 in advance, the structural materials 1 and 2 and the connection members 3 and 4 are made into one part. Therefore, it is not necessary to handle the plate 300 as shown in FIG. Furthermore, since the connecting members 3 and 4 are simply attached to the side portions (A side or B side) of the structural materials 1 and 2 in a protruding state, the end portions 1a and 2a of the structural materials 1 and 2 are provided. There is no need to process or special shapes, and there is no need for on-site processing.
 また、突出部32,42(接続部材3,4)を構造材1,2の片側の側部(A側またはB側)に対して固定するようにしているので、接続部材3,4やボルトなどの締結具51が、構造材1,2の表面側(縁部側)へ突出しない構造とすることができる。よって、構造材1,2間の継手構造は、フランジ部62の外表面に、図11のようなボルト(締結具51)や添え板300などによる凹凸や突起のない平坦で面一なものとなり、見栄えがよい。 Moreover, since the protrusions 32 and 42 (connection members 3 and 4) are fixed to one side (A side or B side) of the structural members 1 and 2, the connection members 3 and 4 and the bolts It can be set as the structure which the fasteners 51 etc. do not protrude to the surface side (edge part side) of the structural materials 1 and 2.

You may do it. Thereby, the structural materials 1 and 2 can be efficiently and highly connected with a small number of bolts.
 (効果3)突出部32,42を、構造材1,2の端部1a,2aにおける片側の側部(A側またはB側)に基部31,41を固定され、先端側部分が構造材1,2の端部1a,2aから長手方向55へ突出された接続部材3,4によって構成した。これにより、構造材1,2に確実に突出部32,42を設けることができる。 (Effect 3) The protrusions 32 and 42 are fixed to the base portions 31 and 41 on one side (A side or B side) of the end portions 1a and 2a of the structural materials 1 and 2, and the distal end portion is the structural material 1. The connecting members 3 and 4 project in the longitudinal direction 55 from the end portions 1a and 2a. Thereby, the protrusion parts 32 and 42 can be reliably provided in the structural materials 1 and 2.
 また、2本の構造材1,2を、互いに端部1a,2aを向かい合わせにして近接させると共に、各突出部42,32が互いに反対側に位置するように相手方の構造材2,1の端部2a,1aの側部に重ねた状態で、2本の構造材1,2を、直線状に接続するようにしてもよい。これにより、2本の構造材1,2を、容易且つ確実に、芯ズレや段差を生じることなく直線状に接続することができる。 Also, the two structural members 1 and 2 are brought close to each other with their end portions 1a and 2a facing each other, and the other structural members 2 and 1 are positioned so that the projecting portions 42 and 32 are located on opposite sides. You may make it connect the two structural materials 1 and 2 linearly in the state piled up on the side part of the edge parts 2a and 1a.
