Description

本発明は、接合部材に関する。 The present invention relates to a joining member.

例えばＲＣ梁または壁と大梁との間、または大梁と小梁との間の梁端接合部は、一般的に剛接合またはピン接合として設計される。大梁と小梁との例でいうと、剛接合の場合には小梁のフランジを大梁に溶接またはボルト接合し、さらに小梁のウェブを大梁にボルト接合する。ピン接合の場合、小梁のウェブを大梁に取り付けたシアプレートにボルト接合し、小梁のフランジは大梁に接合しない。 Beam end connections, for example between RC beams or walls and girders, or between girders and sub-beams, are generally designed as rigid or pin connections. Taking the example of a large beam and a small beam, in the case of a rigid connection, the flange of the small beam is welded or bolted to the large beam, and the web of the small beam is bolted to the large beam. In the case of a pin connection, the web of the beam is bolted to the shear plate attached to the girder, and the flanges of the beam are not connected to the girder.

これに対して、非特許文献１には、水平力を負担しないグラビティフレームや、水平力が小さく逆対称曲げにならない場合のモーメントフレームなど、接合部のモーメントが逆転しない荷重条件下におけるコンタクトプレートを用いた接合が記載されている。コンタクトプレートは、被接触部材である鉄骨梁の下側フランジの小端面と支持部材との間の隙間に介挿され、鉄骨梁の圧縮側フランジの力を対向する支持部材に伝達する。 On the other hand, Non-Patent Document 1 describes contact plates that are used under load conditions where the moment at the joint does not reverse, such as a gravity frame that does not bear horizontal force or a moment frame that does not cause antisymmetrical bending when the horizontal force is small. The connections used are described. The contact plate is inserted into the gap between the small end surface of the lower flange of the steel beam, which is the member to be contacted, and the support member, and transmits the force of the compression side flange of the steel beam to the opposing support member.

ところが、一般に、鉄骨梁の下側フランジの小端面と支持部材との間の隙間は、建方精度のばらつきなどによってその寸法が変動する。コンタクトプレートの厚みが隙間の寸法に対応していなければ力は伝達されないため、コンタクトプレートの厚みを可変にする必要がある。具体的には、特許文献１では、コンタクトプレートに相当する部材をくさび状にすることによって隙間の寸法変動に対応する技術が記載されている。 However, in general, the dimension of the gap between the small end face of the lower flange of the steel beam and the support member fluctuates due to variations in construction accuracy. If the thickness of the contact plate does not correspond to the dimensions of the gap, no force will be transmitted, so it is necessary to make the thickness of the contact plate variable. Specifically, Patent Document 1 describes a technique for responding to dimensional variations in the gap by forming a member corresponding to a contact plate into a wedge shape.

EUROPEAN COMMITTEE FOR STANDARDIZATION、「Eurocode 4: Design of Composite Steel and Concrete Structures Part 1-8: Design of joints」、２００５年５月EUROPEAN COMMITTEE FOR STANDARDIZATION, "Eurocode 4: Design of Composite Steel and Concrete Structures Part 1-8: Design of joints", May 2005

しかしながら、特許文献１に記載された技術のようにコンタクトプレートに相当する部材をくさび状にした場合、鉄骨梁の下側フランジの小端面または支持部材の少なくともいずれかとの間の接触領域がフランジ板厚に対して狭幅になる。この場合、下側フランジの断面積に比べてメタルタッチ部の面積が小さくなるため、局所圧縮状態が発生し、作用する圧縮力に対して接触部分が塑性化したり、剛性および耐力が安定しないために設計が困難になったりする可能性がある。 However, when the member corresponding to the contact plate is formed into a wedge shape as in the technique described in Patent Document 1, the contact area between the small end face of the lower flange of the steel beam or at least one of the supporting member is the flange plate. The width is narrow compared to the thickness. In this case, since the area of the metal touch part is smaller than the cross-sectional area of the lower flange, a local compression state occurs, and the contact part becomes plastic due to the applied compressive force, and the rigidity and yield strength become unstable. design may become difficult.

また、上記のようにくさび状の部材を用いる場合、接合構造を形成する鉄骨梁が支持部材に対して所定の位置に配置された後でなければ、下側フランジと支持部材との間にくさび状の部材を介挿することができない。一般に接合構造の施工箇所は高所であるため、くさび状の部材を施工箇所まで持ち運ぶ手間が煩雑である、くさび状の部材が施工中に落下したり、施工後に脱落したりする可能性がある、といった施工上の不便があった。 Furthermore, when using a wedge-shaped member as described above, the wedge-shaped member must be formed between the lower flange and the supporting member only after the steel beams forming the joint structure are placed in a predetermined position with respect to the supporting member. It is not possible to insert a shaped member. Generally, the construction site for jointed structures is at a high place, so it is troublesome to carry the wedge-shaped members to the construction site, and there is a possibility that the wedge-shaped components may fall during construction or fall off after construction. There were construction inconveniences such as.

そこで、本発明は、隙間の寸法が変動する部材間に安定して介挿することが可能でありつつ、施工上の不便を最小化することが可能な接合部材を提供することを目的とする。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a joining member that can be stably inserted between members whose gap dimensions vary while minimizing construction inconvenience. .

以下に添付図面を参照しながら、本発明の好適な実施形態について詳細に説明する。なお、本明細書および図面において、実質的に同一の機能構成を有する構成要素については、同一の符号を付することにより重複説明を省略する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Note that, in this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals and redundant explanation will be omitted.

図１は、本発明の一実施形態に係る接合部材の斜視図である。図示された例において、接合部材１０は、第１部材１１と、第２部材１２と、ボルト１３と、ナット１４とを含む。接合部材１０は、互いに対向する２つの被接合部材の面の間に介挿される。被接合部材は、例えば後述する例のようにＨ形断面梁の下フランジや、Ｈ形断面梁に接合されるリブなどである。以下では、第１部材１１および第２部材１２が互いに対向する側をそれぞれの前側、第１部材１１および第２部材１２がそれぞれの被接合部材に対向する側をそれぞれの後側として、各部材の構成について説明する。 FIG. 1 is a perspective view of a joining member according to an embodiment of the present invention. In the illustrated example, the joining member 10 includes a first member 11, a second member 12, a bolt 13, and a nut 14. The joining member 10 is inserted between the surfaces of two members to be joined that face each other. The member to be joined is, for example, a lower flange of an H-shaped cross-section beam, a rib to be joined to the H-shaped cross-section beam, etc. as in the example described later. In the following, each member is referred to as a front side where the first member 11 and the second member 12 face each other, and a rear side where the first member 11 and second member 12 face each member to be joined. The configuration of is explained below.

第１部材１１は、第１後接触面１１１と、第１後接触面１１１に対して傾斜した第１前接触面１１２とを有する。図示された例において、第１部材１１の後側には後述するように被接合部材の板状部分を挿入することが可能な溝部１１３が形成され、第１後接触面１１１は溝部１１３の底面１１３Ｂを形成する。この場合、第１後接触面１１１は、溝部１１３に挿入された被接合部材の板状部分の端面に接触する。また、図示された例において、第１部材１１には後述するボルト１３が螺合する貫通ねじ孔１１４が形成される。 The first member 11 has a first rear contact surface 111 and a first front contact surface 112 that is inclined with respect to the first rear contact surface 111 . In the illustrated example, a groove 113 is formed on the rear side of the first member 11 into which a plate-shaped portion of a member to be joined can be inserted, as described later, and the first rear contact surface 111 is the bottom surface of the groove 113. 113B is formed. In this case, the first rear contact surface 111 contacts the end surface of the plate-shaped portion of the member to be joined inserted into the groove 113. Furthermore, in the illustrated example, the first member 11 is formed with a through screw hole 114 into which a bolt 13, which will be described later, is screwed.

第２部材１２は、第２後接触面１２１と、第２後接触面１２１に対して傾斜し第１部材１１の第１前接触面１１２に接触する第２前接触面１２２とを有する。接合部材１０が被接合部材の互いに対向する面の間に介挿された状態において、被接合部材の面の対向軸（ｘ軸として図示する）に対する第１前接触面１１２および第２前接触面１２２のそれぞれの傾斜角度θ_１，θ_２は互いに補角の関係にある。また、第２部材１２は、ボルト１３が挿通される貫通孔１２４を有する。ボルト１３が第１部材１１に固定されるとともに第２部材１２の貫通孔１２４に挿通されることによって、第１部材１１と第２部材１２とが互いに係合される。 The second member 12 has a second rear contact surface 121 and a second front contact surface 122 that is inclined with respect to the second rear contact surface 121 and contacts the first front contact surface 112 of the first member 11 . In a state where the joining member 10 is inserted between the mutually opposing surfaces of the members to be joined, the first front contact surface 112 and the second front contact surface with respect to the opposing axis (illustrated as the x axis) of the surfaces of the members to be joined. The respective inclination angles θ ₁ and θ ₂ of 122 are complementary angles to each other. Further, the second member 12 has a through hole 124 into which the bolt 13 is inserted. By fixing the bolt 13 to the first member 11 and inserting it into the through hole 124 of the second member 12, the first member 11 and the second member 12 are engaged with each other.

ここで、図１からボルト１３およびナット１４を取り除いた図２に示されるように、貫通孔１２４の形状は、被接合部材の面の対向軸に沿った方向（ｘ軸方向）に延びた第１の部分１２４Ａを含む。第１の部分１２４Ａの長さは、ボルト１３の軸径よりも大きい。これによって、貫通孔１２４および貫通ねじ孔１１４にボルト１３を挿通して第１部材１１が被接合部材に固定された後も、第２部材１２をｘ軸の方向に移動させて第１前接触面１１２と第２前接触面１２２とを互いに摺動させ、図１に示す第１後接触面１１１から第２後接触面１２１までの距離Ｄを被接合部材の面の間の隙間の大きさに応じて調節することができる。 Here, as shown in FIG. 2 in which the bolt 13 and nut 14 are removed from FIG. 1 portion 124A. The length of the first portion 124A is greater than the shaft diameter of the bolt 13. As a result, even after the first member 11 is fixed to the member to be joined by inserting the bolt 13 into the through hole 124 and the through screw hole 114, the second member 12 can be moved in the x-axis direction to make the first front contact. The surface 112 and the second front contact surface 122 are slid against each other, and the distance D from the first rear contact surface 111 to the second rear contact surface 121 shown in FIG. 1 is determined as the size of the gap between the surfaces of the members to be joined. It can be adjusted accordingly.

なお、本明細書において、被接合部材の面の対向軸（ｘ軸）は、互いに対向する２つの被接合部材の面の少なくとも一方に直交する軸として定義される。接合部材１０では、第１後接触面１１１および第２後接触面１２１が、互いに対向する２つの被接合部材の面にそれぞれ一致する。後述する図３や図７に示された例のように互いに対向する２つの被接合部材の面が互いに平行である場合、２つの被接合部材の面の両方に直交する対向軸が定義される。また、加工誤差や斜角の形成のために２つの被接合部材の面が平行ではない場合、２つの被接合部材の面のいずれか一方に直交する対向軸が定義される。この場合も、上述のように、対向軸に対する第１前接触面１１２および第２前接触面１２２のそれぞれの傾斜角度θ１，θ２は互いに補角の関係にある。また、貫通孔１２４の形状が対向軸に沿った方向に延びた第１の部分１２４Ａを含むことによって、第２部材１２を対向軸に沿った方向に移動させて第１前接触面１１２と第２前接触面１２２とを互いに摺動させることができる。ここで、例えば貫通孔１２４が形成される第２部材１２の上面が対向軸に対して平行ではないような場合、貫通孔１２４の第１の部分１２４Ａは対向軸に沿った方向にのみ延びるわけではないが、このような場合も第２部材１２を対向軸に沿った方向を含む方向に移動させることによって、上記と同様の効果を得ることができる。 Note that in this specification, the opposing axis (x-axis) of the surfaces of the members to be joined is defined as an axis perpendicular to at least one of the surfaces of the two members to be joined that face each other. In the joining member 10, the first rear contact surface 111 and the second rear contact surface 121 respectively correspond to the surfaces of two members to be joined that face each other. When the surfaces of two members to be joined that face each other are parallel to each other, as in the examples shown in FIGS. 3 and 7, which will be described later, an opposing axis is defined that is orthogonal to both the surfaces of the two members to be joined. . Furthermore, when the surfaces of the two members to be joined are not parallel due to processing errors or formation of an oblique angle, an opposing axis perpendicular to one of the surfaces of the two members to be joined is defined. Also in this case, as described above, the respective inclination angles θ1 and θ2 of the first front contact surface 112 and the second front contact surface 122 with respect to the opposing axis are complementary angles to each other. In addition, since the shape of the through hole 124 includes the first portion 124A extending in the direction along the opposing axis, the second member 12 can be moved in the direction along the opposing axis to connect the first front contact surface 112 and the first portion 124A. The two front contact surfaces 122 can be slid against each other. Here, for example, if the upper surface of the second member 12 on which the through hole 124 is formed is not parallel to the opposing axis, the first portion 124A of the through hole 124 extends only in the direction along the opposing axis. However, even in such a case, the same effect as described above can be obtained by moving the second member 12 in a direction including the direction along the opposing axis.

さらに、本実施形態において、貫通孔１２４の形状は、第１の部分１２４Ａに交差する方向に延びた第２の部分１２４Ｂをさらに含む。貫通孔１２４に挿通されたボルト１３を第２の部分１２４Ｂに押し込むことによって、第１前接触面１１２と第２前接触面１２２との間の摺動が規制され、第１後接触面１１１から第２後接触面１２１までの距離Ｄが固定される。例えば、距離Ｄが最小になったときにボルト１３が位置する第１の部分１２４Ａの端部に第２の部分１２４Ｂが交差するようなＬ字形に貫通孔１２４を形成することによって、後述する例のように距離Ｄが最小の状態で第１部材１１に第２部材１２を固定することができる。 Furthermore, in this embodiment, the shape of the through hole 124 further includes a second portion 124B extending in a direction intersecting the first portion 124A. By pushing the bolt 13 inserted into the through hole 124 into the second portion 124B, sliding between the first front contact surface 112 and the second front contact surface 122 is regulated, and from the first rear contact surface 111 The distance D to the second rear contact surface 121 is fixed. For example, by forming the through hole 124 in an L-shape such that the second portion 124B intersects the end of the first portion 124A where the bolt 13 is located when the distance D becomes the minimum, an example described later may be formed. The second member 12 can be fixed to the first member 11 with the minimum distance D as shown in FIG.

ボルト１３は、第１部材１１に固定され、第２部材１２の貫通孔１２４に挿通される棒状部材の例である。本実施形態において、ボルト１３は頭部１３１を除く全長にわたってねじ溝を有し、貫通ねじ孔１１４に螺合することによって第１部材１１に固定される。また、ナット１４がボルト１３に螺合し、第１部材１１とは反対側から第２部材１２に向かって締め付けることが可能なように配置される。第１部材１１と第２部材１２との間でボルト１３に螺合する追加のナットが配置され、ナット１４との間で第２部材１２を挟み込むダブルナットを形成してもよい。ナット１４を配置することによって、後述する例のように適切な距離Ｄを設定した状態で第１部材１１と第２部材１２との位置関係を固定することができる。 The bolt 13 is an example of a rod-shaped member that is fixed to the first member 11 and inserted into the through hole 124 of the second member 12. In this embodiment, the bolt 13 has a thread groove over its entire length except for the head 131, and is fixed to the first member 11 by being screwed into the through-screw hole 114. Further, the nut 14 is screwed onto the bolt 13 and is arranged so that it can be tightened from the opposite side to the first member 11 toward the second member 12 . An additional nut screwed onto the bolt 13 may be arranged between the first member 11 and the second member 12, and a double nut may be formed in which the second member 12 is sandwiched between the nut 14 and the nut 14. By arranging the nut 14, the positional relationship between the first member 11 and the second member 12 can be fixed with an appropriate distance D set as in the example described later.

さらに、本実施形態では、ボルト１３が第１部材１１の貫通ねじ孔１１４を貫通して溝部１１３の側面１１３Ｓから突出する。これによって、溝部１１３に被接合部材の板状部分が挿入された場合、ボルト１３の端部を被接合部材の板状部分の板面に接触させ、対向する溝部１１３の側面との間で板状部分を締め付けることができる。これによって、溝部１１３に被接合部材の板状部分を挿入したときに、第１部材１１が板状部分から脱落することをより確実に防止できる。 Furthermore, in this embodiment, the bolt 13 passes through the through screw hole 114 of the first member 11 and protrudes from the side surface 113S of the groove portion 113. As a result, when the plate-shaped part of the member to be joined is inserted into the groove 113, the end of the bolt 13 is brought into contact with the plate surface of the plate-shaped part of the member to be joined, and the plate is inserted between the opposing side surface of the groove 113. The shaped part can be tightened. Thereby, when the plate-shaped portion of the member to be joined is inserted into the groove portion 113, it is possible to more reliably prevent the first member 11 from falling off from the plate-shaped portion.

なお、他の実施形態において、ボルト１３は必ずしも第１部材１１を貫通しなくてもよい。例えば、ボルト１３が配置されるのとは反対側（図１では下側）の溝部１１３の側面から突出するボルトが別途配置されてもよい。あるいは、被接合部材の板状部分の厚さが一定であり、溝部１１３が板状部分の厚さに対応する幅で形成されている場合、ボルト１３による締め付けがなくても第１部材１１は板状部分から脱落しない。逆にいえば、ボルトによって溝部１１３に挿入された板状部分を締め付けられる構成にすることによって、溝部１１３に挿入される板状部分の厚さが一定でなく、板状部分の厚さと溝部１１３の幅とが対応しない場合にも、第１部材１１が板状部分から脱落することを防止できる。 Note that in other embodiments, the bolt 13 does not necessarily need to penetrate the first member 11. For example, a bolt may be separately arranged that protrudes from the side surface of the groove 113 on the side opposite to where the bolt 13 is arranged (lower side in FIG. 1). Alternatively, if the thickness of the plate-shaped portion of the members to be joined is constant and the groove portion 113 is formed with a width corresponding to the thickness of the plate-shaped portion, the first member 11 can be moved without being tightened by the bolt 13. It will not fall off the plate-like part. Conversely, by configuring the plate-shaped part inserted into the groove 113 to be tightened by bolts, the thickness of the plate-shaped part inserted into the groove 113 is not constant, and the thickness of the plate-shaped part and the groove 113 are different. Even if the width of the first member 11 does not correspond to the width of the first member 11, it is possible to prevent the first member 11 from falling off from the plate-shaped portion.

また、さらに他の実施形態において、ボルト１３は第１部材に螺合によって固定されなくてもよい。例えば、ボルト１３は第１部材１１に溶接されてもよい。この場合、ボルト１３の第１部材１１側の部分にはねじ溝が形成されなくてもよい。また、ナット１４が設けられない場合は、ボルト１３の中間部分にねじ溝が形成されなくてもよい。この場合、ボルト１３ではなくねじ溝を有さない棒状部材が配置される。棒状部材の場合、ボルト１３のような頭部１３１は設けられなくてもよい。また、ボルト１３の場合も、例えば頭なしボルトを用いることによって頭部１３１を設けなくてもよい。 In still other embodiments, the bolt 13 does not need to be fixed to the first member by threading. For example, the bolt 13 may be welded to the first member 11. In this case, a thread groove may not be formed in the portion of the bolt 13 on the first member 11 side. Moreover, when the nut 14 is not provided, the thread groove does not need to be formed in the intermediate portion of the bolt 13. In this case, instead of the bolt 13, a rod-shaped member without a thread groove is arranged. In the case of a rod-shaped member, the head 131 like the bolt 13 may not be provided. Also, in the case of the bolt 13, the head 131 may not be provided by using a headless bolt, for example.

図３は、図１に示した接合部材を含む接合構造の斜視図である。図示された例において、接合構造は、小梁２とリブ３１との間に形成される。小梁２は、上フランジ２１、ウェブ２２および下フランジ２３を含むＨ形断面梁である。リブ３１は、上フランジ４１、ウェブ４２および下フランジ４３を有するＨ形断面梁である大梁４に、フィンプレート３２とともに溶接される。接合部材１０は、小梁２の下フランジ２３を第１被接合部材、リブ３１を第２被接合部材として、互いに対向する下フランジ２３の端面２３Ｅとリブ３１の端面３１Ｅとの間に介挿される。 FIG. 3 is a perspective view of a joining structure including the joining member shown in FIG. 1. In the illustrated example, the joining structure is formed between the beam 2 and the rib 31. The small beam 2 is an H-shaped cross-section beam including an upper flange 21, a web 22 and a lower flange 23. The rib 31 is welded together with the fin plate 32 to the girder 4, which is an H-shaped cross-section beam having an upper flange 41, a web 42 and a lower flange 43. The joining member 10 is inserted between an end surface 23E of the lower flange 23 and an end surface 31E of the rib 31, which are opposite to each other, with the lower flange 23 of the small beam 2 as a first member to be joined and the rib 31 as a second member to be joined. It will be done.

上記のような接合構造において、小梁２は、ウェブ２２の端部でフィンプレート３２に接合される。ウェブ２２とフィンプレート３２との接合は、例えばボルト３３を用いた接合であってもよいし、溶接であってもよい。ウェブ２２とフィンプレート３２との接合によって、小梁２の軸方向の圧縮力および引張力、ならびにせん断力が伝達される。小梁２は、下フランジ２３の端面２３Ｅで接合部材１０を介してリブ３１の端面３１Ｅに接触する。下フランジ２３の端面２３Ｅとリブ３１の端面３１Ｅとの接触によって、小梁２の軸方向の圧縮力が大梁４に伝達される。 In the joining structure as described above, the beam 2 is joined to the fin plate 32 at the end of the web 22. The web 22 and the fin plate 32 may be connected, for example, by using bolts 33 or by welding. The connection between the web 22 and the fin plate 32 transmits the compressive and tensile forces in the axial direction of the beam 2, as well as the shear forces. The small beam 2 contacts the end surface 31E of the rib 31 via the joining member 10 at the end surface 23E of the lower flange 23. Due to the contact between the end surface 23E of the lower flange 23 and the end surface 31E of the rib 31, the compressive force in the axial direction of the small beam 2 is transmitted to the large beam 4.

本実施形態では、接合部材１０を適切に配置して、第１部材１１の第１後接触面１１１が下フランジ２３の端面２３Ｅに接触し、第２部材１２の第２後接触面１２１がリブ３１の端面３１Ｅに接触し、かつ第１前接触面１１２と第２前接触面１２２とが互いに接触した状態を維持することによって、圧縮力を効果的に伝達することができる。 In this embodiment, the joining member 10 is appropriately arranged so that the first rear contact surface 111 of the first member 11 contacts the end surface 23E of the lower flange 23, and the second rear contact surface 121 of the second member 12 contacts the rib. By contacting the end surface 31E of 31 and maintaining the state in which the first front contact surface 112 and the second front contact surface 122 are in contact with each other, the compressive force can be effectively transmitted.

図４から図６Ｃは、本発明の一実施形態における接合部材の設置手順の例を示す図である。まず、図４に示された例では、第２部材１２の貫通孔１２４に挿通されたボルト１３が、第２の部分１２４Ｂに押し込まれている。上述のように、本実施形態では貫通孔１２４が第１の部分１２４Ａと第２の部分１２４Ｂとを含むＬ字形に形成されるため、ボルト１３を第２の部分１２４Ｂに押し込むことによって、第１後接触面１１１から第２後接触面１２１までの距離Ｄが最小の状態で第１部材１１を第２部材１２に固定することができる。 4 to 6C are diagrams illustrating an example of a procedure for installing a joining member in an embodiment of the present invention. First, in the example shown in FIG. 4, the bolt 13 inserted into the through hole 124 of the second member 12 is pushed into the second portion 124B. As described above, in this embodiment, the through hole 124 is formed in an L shape including the first portion 124A and the second portion 124B. The first member 11 can be fixed to the second member 12 while the distance D from the rear contact surface 111 to the second rear contact surface 121 is minimized.

例えば、図４に示した状態で第１部材１１の溝部１１３に小梁２の下フランジ２３の端部を挿入し、接合部材１０を小梁２に予め取り付けて施工箇所まで搬送してもよい。ボルト１３が貫通孔１２４の第２の部分１２４Ｂに押し込まれていてもボルト１３の軸回りの回転は可能である。従って、下フランジ２３を溝部１１３に挿入した後に、ボルト１３を回転させて貫通ねじ孔１１４を貫通して溝部１１３の側面１１３Ｓから突出させ、下フランジ２３を締め付けることによって第１部材１１を下フランジ２３に固定してもよい。 For example, the end of the lower flange 23 of the small beam 2 may be inserted into the groove 113 of the first member 11 in the state shown in FIG. 4, and the joining member 10 may be attached to the small beam 2 in advance and transported to the construction site. . Even if the bolt 13 is pushed into the second portion 124B of the through hole 124, the bolt 13 can rotate around the axis. Therefore, after inserting the lower flange 23 into the groove 113, the bolt 13 is rotated to pass through the through screw hole 114 and protrude from the side surface 113S of the groove 113, and by tightening the lower flange 23, the first member 11 is attached to the lower flange. It may be fixed at 23.

次に、図５Ａから図５Ｃに示された例では、第２部材１２の貫通孔１２４に挿通されたボルト１３が、第２の部分１２４Ｂから第１の部分１２４Ａに移り、第１前接触面１１２と第２前接触面１２２との間の摺動が可能になっている。これによって、第１後接触面１１１から第２後接触面１２１までの距離を、図５Ａに示した最小の距離Ｄ_１から、より大きい距離Ｄ_２、最大の距離Ｄ_３まで変化させることができる。例えば、上述のように下フランジ２３に距離Ｄが最小（距離Ｄ_１）の状態で接合部材１０を予め取り付け、下フランジ２３の端面２３Ｅがリブ３１の端面３１Ｅに対向した後に図５Ａから図５Ｃに示したように距離Ｄを徐々に拡大する（距離Ｄ_２および距離Ｄ_３）ことによって、接合部材１０の配置を端面２３Ｅと端面３１Ｅとの間の隙間の大きさに容易に整合させることができる。 Next, in the example shown in FIGS. 5A to 5C, the bolt 13 inserted into the through hole 124 of the second member 12 moves from the second portion 124B to the first portion 124A, and the bolt 13 passes through the first front contact surface. 112 and the second front contact surface 122 is allowed to slide. Thereby, the distance from the first rear contact surface 111 to the second rear contact surface 121 can be changed from the minimum distance D ₁ shown in FIG. 5A to a larger distance D ₂ to the maximum distance D ₃ . . For example, after attaching the joining member 10 to the lower flange 23 in advance with the minimum distance D (distance D ₁ ) as described above, and after the end surface 23E of the lower flange 23 faces the end surface 31E of the rib 31, FIGS. 5A to 5C By gradually increasing the distance D (distance D ₂ and distance D ₃ ) as shown in FIG. can.

さらに、図６Ａから図６Ｃに示された例では、図５Ａから図５Ｃに示されたように様々な距離Ｄで第１部材１１および第２部材１２が配置された状態でナット１４を第２部材１２に向かって締め付けることによって、第１部材１１と第２部材１２との位置関係が固定されている。ナット１４を締め付けると、距離Ｄが小さくなる方向については第１前接触面１１２と第２前接触面１２２との間の摺動が規制されるため、施工後に第１部材１１と第２部材１２との間に相対的な動きが発生したことによって距離Ｄが小さくなり、接合部材１０が被接合部材の面同士の隙間から脱落することを防止できる。 Furthermore, in the example shown in FIGS. 6A to 6C, the nut 14 is moved to the second By tightening toward the member 12, the positional relationship between the first member 11 and the second member 12 is fixed. When the nut 14 is tightened, sliding between the first front contact surface 112 and the second front contact surface 122 is restricted in the direction in which the distance D becomes smaller. As a result of the relative movement between the two surfaces, the distance D becomes smaller, and it is possible to prevent the joining member 10 from falling out of the gap between the surfaces of the members to be joined.

図７は、本発明の一実施形態の変形例に係る接合構造の斜視図である。上記で図３に示した例では接合部材１０の第１部材１１が小梁２の下フランジ２３側に、第２部材１２がリブ３１側に配置されていたが、この配置を逆にし、第１部材１１をリブ３１側に、第２部材１２を下フランジ２３側に配置してもよい。この場合、第１部材１１の溝部１１３にはリブ３１が挿入され、第１後接触面１１１にはリブ３１の端面３１Ｅが接触する。また、第２部材１２の第２後接触面１２１には下フランジ２３の端面２３Ｅが接触する。 FIG. 7 is a perspective view of a joining structure according to a modification of one embodiment of the present invention. In the example shown in FIG. 3 above, the first member 11 of the joining member 10 is arranged on the lower flange 23 side of the small beam 2, and the second member 12 is arranged on the rib 31 side. The first member 11 may be arranged on the rib 31 side, and the second member 12 may be arranged on the lower flange 23 side. In this case, the rib 31 is inserted into the groove 113 of the first member 11, and the end surface 31E of the rib 31 contacts the first rear contact surface 111. Further, the end surface 23E of the lower flange 23 contacts the second rear contact surface 121 of the second member 12.

上記の例に示されるように、本発明の実施形態における接合部材１０の第１部材１１および第２部材１２のそれぞれと、接合構造を構成する被接合部材との関係は特に限定されない。第１部材１１の溝部１１３には、被接合部材の板状部分であればどのようなものが挿入されてもよい。また、第２部材１２の第２後接触面１２１には、図示された例のように板状部材が当接されてもよいし、あるいはより大きい壁面などに第２後接触面１２１が接触させられてもよい。 As shown in the above example, the relationship between each of the first member 11 and second member 12 of the joining member 10 in the embodiment of the present invention and the joined members forming the joining structure is not particularly limited. Any plate-shaped portion of a member to be joined may be inserted into the groove portion 113 of the first member 11 . Further, a plate-like member may be brought into contact with the second rear contact surface 121 of the second member 12 as in the illustrated example, or the second rear contact surface 121 may be brought into contact with a larger wall surface or the like. It's okay to be hit.

以上で説明したような本発明の一実施形態では、接合部材１０を構成する第１部材１１の第１前接触面１１２と第２部材１２の第１前接触面２１２とが傾斜して形成され、かつ互いに対して摺動可能である。従って、接合部材１０は、隙間の寸法が変動する部材間に安定して介挿することができる。また、第１部材１１に固定されたボルト１３が第２部材１２の貫通孔１２４に挿通されるため、第１部材１１と第２部材１２とを互いに係合させ、例えば施工中や施工後における第２部材の脱落を防止することができる。 In one embodiment of the present invention as described above, the first front contact surface 112 of the first member 11 and the first front contact surface 212 of the second member 12 constituting the joining member 10 are formed to be inclined. , and are slidable with respect to each other. Therefore, the joining member 10 can be stably inserted between members whose gap dimensions vary. Further, since the bolt 13 fixed to the first member 11 is inserted into the through hole 124 of the second member 12, the first member 11 and the second member 12 are engaged with each other, and for example, during or after construction. It is possible to prevent the second member from falling off.
