本発明に係る結合部材の一実施形態を添付図面に基づいて説明する。本実施形態においては、第一部材および第二部材が、Ｈ形鋼、山形鋼、溝形鋼、角パイプなどの鋼材（形鋼）であり、結合部材はこれらを連結するために用いられる例を適用して説明する。 An embodiment of a coupling member according to the present invention will be described with reference to the accompanying drawings. In this embodiment, the first member and the second member are steel materials (shaped steel) such as H-shaped steel, angle steel, channel steel, square pipe, etc., and the connecting member is an example used to connect them. is applied to explain.

図１は、Ｈ形鋼２、３を結合する一対の結合部材１を説明する、Ｈ形鋼２の長さ方向（前後方向）視で示す図である。
図２は、Ｈ形鋼２、３を結合する一対の結合部材１を説明する、図１をＨ形鋼２の長さ方向に直交する方向（左方）から示す図である。 FIG. 1 is a view showing a longitudinal direction (front-rear direction) of an H-section steel 2, explaining a pair of connecting members 1 that connect H-section steels 2 and 3. FIG.
FIG. 2 is a view showing FIG. 1 from a direction perpendicular to the length direction (left side) of the H-section steel 2, explaining a pair of connecting members 1 that connect the H-section steels 2 and 3. FIG.

以下の説明においては、「上」、「下」、「右」、「左」、「前」、「後」は、図１から図６における定義に従う。上下方向は鉛直面に含まれ、左右方向および前後方向は水平面に含まれる方向である。また、上下および左右方向に直交する方向を、前後方向という。 In the following description, "top", "bottom", "right", "left", "front", and "back" follow the definitions in FIGS. The up-down direction is included in the vertical plane, and the left-right direction and the front-back direction are included in the horizontal plane. A direction orthogonal to the up-down and left-right directions is referred to as the front-rear direction.

一対の結合部材１は、天井に取り付けられた既設のＨ形鋼２（第一部材、「既設Ｈ形鋼２」という）に新たなＨ形鋼３（第二部材、「連結Ｈ形鋼３」という）を、例えば天井部分の耐震増強を行うために結合するための部材である。既設Ｈ形鋼２は、水平方向（前後方向）に伸びて配置され、連結Ｈ形鋼３はこの既設Ｈ形鋼２に直交するように鉛直方向に伸びて配置される。 A pair of connecting members 1 is a new H-section steel 3 (second member, "connecting H-section steel 3 ), for example, to reinforce the seismic resistance of the ceiling. The existing H-section steel 2 is arranged to extend in the horizontal direction (longitudinal direction), and the connecting H-section steel 3 is arranged to extend in the vertical direction so as to be orthogonal to the existing H-section steel 2 .

既設Ｈ形鋼２は、水平方向に沿う水平面（第一面）に沿う（左右および前後方向に沿う）一対のフランジ２ａ、２ｂと、フランジ２ａ、２ｂに直交する鉛直方向に沿う鉛直面（第二面）に沿う（上下および前後方向に沿う）ウェブ２ｃと、を有する。ウェブ２ｃの下端からウェブ２ｃに関して対称に水平方向に伸びる下側のフランジ２ｂは、結合部材１を介して連結Ｈ形鋼３が取り付けられる取付面となる。 The existing H-section steel 2 has a pair of flanges 2a and 2b (along the left-right and front-rear directions) along a horizontal plane (first plane) along the horizontal direction, and a vertical plane (first plane) along the vertical direction orthogonal to the flanges 2a and 2b. and a web 2c along two planes (along the vertical and longitudinal directions). A lower flange 2b extending horizontally symmetrically with respect to the web 2c from the lower end of the web 2c serves as a mounting surface to which the connecting H-section steel 3 is mounted via the connecting member 1. As shown in FIG.

連結Ｈ形鋼３は、鉛直方向に伸びて配置される。連結Ｈ形鋼３は、ウェブ３ｃと、一対のフランジ３ａ、３ｂと、を有する。ウェブ３ｃは、ウェブ２ｃが沿う面とほぼ同一の鉛直面に沿う（上下および前後方向に沿う）。一対のフランジ３ａ、３ｂは、フランジ２ａ、２ｂが沿う水平面およびウェブ２ｃが沿う鉛直面に直交する鉛直面（第三面）に沿う（上下および左右方向に沿う）。連結Ｈ形鋼３の上端においては、上端から一定領域のフランジ３ａ、３ｂが切り欠かれており、ウェブ３ｄのみが形成される。この上端部分のウェブ３ｄは、結合部材１を介して既設Ｈ形鋼２が取り付けられる被取付面となる。ウェブ３ｄは、後述するボルト３０を貫通させるボルト孔３ｅを有する。 The connecting H-section steel 3 is arranged to extend in the vertical direction. The connecting H-section steel 3 has a web 3c and a pair of flanges 3a, 3b. The web 3c runs along substantially the same vertical plane as the plane along which the web 2c runs (along vertical and front-back directions). The pair of flanges 3a and 3b extend along a vertical plane (third surface) orthogonal to the horizontal plane along which the flanges 2a and 2b extend and the vertical plane along which the web 2c extends (along the vertical and horizontal directions). At the upper end of the connecting H-section steel 3, the flanges 3a and 3b are cut out in a certain area from the upper end, and only the web 3d is formed. The web 3 d at the upper end portion serves as a mounting surface to which the existing H-shaped steel 2 is mounted via the connecting member 1 . The web 3d has bolt holes 3e through which bolts 30, which will be described later, pass.

一対の結合部材１は、ウェブ２ｃに関して対称に配置される、二つの結合部材１である。一対の結合部材１は、同一形状を有するため、以下の説明においては図１の右方の結合部材１について説明する。 A pair of connecting members 1 are two connecting members 1 arranged symmetrically with respect to the web 2c. Since the pair of connecting members 1 have the same shape, the connecting member 1 on the right side in FIG. 1 will be described in the following description.

結合部材１は、フランジ支持部１０（第一部材支持部）と、ウェブ支持部２０（第二部材支持部）と、ボルト３０およびナット３１（固定部）と、を有する。 The coupling member 1 has a flange supporting portion 10 (first member supporting portion), a web supporting portion 20 (second member supporting portion), and bolts 30 and nuts 31 (fixing portion).

フランジ支持部１０は、図１に示すように縦断面略コ字状を有し、一対の挟持部１１と、接続部１５と、を有する。一対の挟持部１１は、フランジ２ｂを挟み込む、鉛直方向に対面する二枚の板状部分である。下側の挟持部１１の左端は、上側の挟持部１１の左端よりも左方であって、ウェブ２ｃの略下方まで伸びている。接続部１５は、一対の挟持部１１の右端を鉛直方向において接続する。 The flange support portion 10 has a substantially U-shaped vertical cross section as shown in FIG. The pair of sandwiching portions 11 are two plate-shaped portions that sandwich the flange 2b and face each other in the vertical direction. The left end of the lower holding portion 11 is to the left of the left end of the upper holding portion 11 and extends substantially below the web 2c. The connecting portion 15 connects the right ends of the pair of holding portions 11 in the vertical direction.

接続部１５は、フランジ２ｂと対面する内表面に、凸部１６を有する。凸部１６は、フランジ２ｂに接触して摩擦を生じ、フランジ２ｂに対する結合部材１の滑り止め（既設Ｈ形鋼２の伸びる方向に関する横滑り防止）として作用する。 The connecting portion 15 has a convex portion 16 on the inner surface facing the flange 2b. The convex portion 16 contacts the flange 2b to generate friction, and acts as a slip prevention of the coupling member 1 against the flange 2b (prevention of side slip in the direction in which the existing H-section steel 2 extends).

挟持部１１および接続部１５は、ボルト孔１８を有する。ボルト孔１８は、滑り止めボルト１９を貫通させる。滑り止めボルト１９は、フランジ支持部１０をフランジ２ｂに対して締め付けることで、凸部１６同様に結合部材１の滑り止めとして作用する。 The clamping portion 11 and the connecting portion 15 have bolt holes 18 . A non-slip bolt 19 is passed through the bolt hole 18 . The non-slip bolt 19 acts as a non-slip for the coupling member 1 in the same manner as the convex portion 16 by tightening the flange support portion 10 against the flange 2b.

なお、凸部１６は、説明の都合上図１の右側の結合部材１にのみ図示されている。また、ボルト孔１８および滑り止めボルト１９は、説明の都合上左側の結合部材１にのみ図示されている。しかしながら、凸部１６、ボルト孔１８および滑り止めボルト１９は、右側および左側の結合部材１の両者に、それぞれ設けられる。 Incidentally, the projection 16 is shown only on the right coupling member 1 in FIG. 1 for convenience of explanation. Also, the bolt holes 18 and the non-slip bolts 19 are shown only on the left coupling member 1 for convenience of explanation. However, projections 16, bolt holes 18 and anti-slip bolts 19 are provided on both the right and left coupling members 1, respectively.

ウェブ支持部２０は、下側の挟持部１１（一対の挟持部１１の一方）の左端から鉛直面に沿って伸びる板状部分である。フランジ支持部１０およびウェブ支持部２０は、縦断面視において略Ｌ字状をなす。ウェブ支持部２０は、ボルト孔２１を有する。一対のフランジ支持部１０がフランジ２ｂを挟み込むようにフランジ２ｂに取り付けられると、一対のウェブ支持部２０は少なくともウェブ３ｄの厚さの空間を隔てて対面する。 The web support portion 20 is a plate-like portion extending along the vertical plane from the left end of the lower holding portion 11 (one of the pair of holding portions 11). The flange support portion 10 and the web support portion 20 are substantially L-shaped in longitudinal cross-sectional view. Web support 20 has bolt holes 21 . When the pair of flange support portions 10 are attached to the flange 2b so as to sandwich the flange 2b, the pair of web support portions 20 face each other with a space of at least the thickness of the web 3d.

ボルト３０およびナット３１は、一対のウェブ支持部２０が形成する空間にウェブ３ｄが挿入された状態で、ウェブ支持部２０のボルト孔２１およびウェブ３ｄのボルト孔３ｅを貫通して締め付けられる。これにより、ボルト３０およびナット３１は、ウェブ支持部２０とウェブ３ｄとを固定する。 The bolt 30 and the nut 31 are tightened through the bolt hole 21 of the web support portion 20 and the bolt hole 3e of the web 3d while the web 3d is inserted into the space formed by the pair of web support portions 20 . The bolts 30 and nuts 31 thereby fix the web support portion 20 and the web 3d.

このような結合部材１は、次のように既設Ｈ形鋼２および連結Ｈ形鋼３を結合する。 Such a connecting member 1 connects the existing H-section steel 2 and the connecting H-section steel 3 as follows.

一対の結合部材１は、フランジ支持部１０で既設Ｈ形鋼２の下側のフランジ２ｂをウェブ２ｃに関して左右対称に挟み込むように、それぞれフランジ２ｂに取り付けられる。このとき、凸部１６がフランジ２ｂに接触するので、結合部材１は既設Ｈ形鋼２の伸びる方向に対して横滑りすることを低減できる。また、ボルト孔１８を介して滑り止めボルト１９がフランジ支持部１０およびフランジ２ｂを締め付けるため、同様に結合部材１は横滑りを低減できる。 A pair of connecting members 1 are attached to the flanges 2b so that the lower flanges 2b of the existing H-section steel 2 are sandwiched by the flange support portions 10 symmetrically with respect to the web 2c. At this time, since the convex portion 16 contacts the flange 2b, the side slip of the connecting member 1 in the direction in which the existing H-section steel 2 extends can be reduced. Further, since the non-slip bolts 19 tighten the flange support portion 10 and the flange 2b through the bolt holes 18, the coupling member 1 can similarly reduce lateral slip.

この状態で、一対のウェブ支持部２０は、空間を隔てて対面した状態となる。この空間に、連結Ｈ形鋼３のウェブ３ｄが挿入される。すなわち、一対のウェブ支持部２０は、ウェブ２ｃに関して左右対称に、ウェブ３ｄを挟み込む。その後、一対のウェブ支持部２０のボルト孔２１およびウェブ３ｄのボルト孔３ｅに、ボルト３０が挿入され、ナット３１とともに締められることにより、固定部としてのボルト３０およびナット３１が一対のウェブ支持部２０およびウェブ３ｄを固定する。これにより、既設Ｈ形鋼２および連結Ｈ形鋼３は、強固に結合される。 In this state, the pair of web supporting portions 20 face each other with a space therebetween. A web 3d of the connecting H-section steel 3 is inserted into this space. That is, the pair of web supporting portions 20 sandwich the web 3d symmetrically with respect to the web 2c. After that, the bolt 30 is inserted into the bolt hole 21 of the pair of web support portions 20 and the bolt hole 3e of the web 3d, and is tightened together with the nut 31, so that the bolt 30 and the nut 31 as the fixing portion are connected to the pair of web support portions. 20 and web 3d are fixed. As a result, the existing H-section steel 2 and the connecting H-section steel 3 are firmly combined.

このような結合部材１は、既設Ｈ形鋼２および連結Ｈ形鋼３の結合を、簡素な構成で実現できる。すなわち、連結Ｈ形鋼３を結合するために、ガセットプレートに相当する（例えば特許文献１の第２プレート部材３０のような）部材を用意する必要がなく、結合部材１により直接連結Ｈ形鋼３を結合できる。特に、結合部材１は、既設Ｈ形鋼２にフランジ支持部１０を挟み込み、その後ウェブ支持部２０に連結Ｈ形鋼３（ウェブ３ｄ）を挟み込み、最後にボルト３０およびナット３１で締め付けるという少ない工程、および簡素な作業内容で、二つの鋼材を連結できる。 Such a joining member 1 can achieve joining of the existing H-section steel 2 and the connecting H-section steel 3 with a simple configuration. That is, in order to connect the connecting H-section steels 3, there is no need to prepare a member corresponding to a gusset plate (such as the second plate member 30 of Patent Document 1), and the connecting member 1 directly connects the H-section steels. 3 can be combined. In particular, the joining member 1 can be manufactured by inserting the flange support portion 10 into the existing H-section steel 2, then inserting the connecting H-section steel 3 (web 3d) into the web support portion 20, and finally tightening it with the bolt 30 and the nut 31. , and simple work contents can connect two steel materials.

本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 While several embodiments of the invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the scope of the invention described in the claims and equivalents thereof.

例えば、設計上、フランジ支持部１０にさらなる強度が要求される場合には、フランジ支持部１０の外表面を覆うような、リブ状などの補強構造を設けてもよい。この補強構造は、例えば溶接などによりフランジ支持部１０の外表面に取り付けられる。 For example, if the flange support portion 10 is required to have greater strength in terms of design, a reinforcing structure such as a rib that covers the outer surface of the flange support portion 10 may be provided. This reinforcing structure is attached to the outer surface of the flange support 10, such as by welding.

また、フランジ支持部１０およびウェブ支持部２０の境界部分（角部分）の強度を増すために、フランジ支持部１０およびウェブ支持部２０に渡るリブ状などの補強構造を設けてもよい。この補強構造は、例えば溶接などによりフランジ支持部１０およびウェブ支持部２０の外表面に取り付けられる。 Moreover, in order to increase the strength of the boundary portion (corner portion) between the flange support portion 10 and the web support portion 20, a reinforcing structure such as a rib extending over the flange support portion 10 and the web support portion 20 may be provided. The reinforcement structure is attached to the outer surfaces of the flange support 10 and web support 20, such as by welding.

さらに、第一部材および第二部材がＨ形鋼である例を説明したが、これに限らずフランジを有する山形鋼や溝形鋼、角パイプなどの鋼材であってもよい。例えば、図３は、変形例としての結合部材１０１を説明する図である。第一部材が山形鋼または溝形鋼などの既設形鋼１０２である場合には、フランジ１０２ｂがウェブ１０２ｃの下端から一方向（図２においては右方向）にのみ伸びており、フランジ支持部１１０が挟み込む対象は一つであるため、結合部材１０１は１つのみ用いられる。この場合には、ウェブ支持部１２０とともにウェブ１０３ｄを挟み、ボルト１３０およびナット１３１を締め付けるための、支持部材１４０が用いられるのが好ましい。支持部材１４０は、例えばウェブ１０２ｃおよび連結形鋼１０３のウェブ１０３ｃの面に沿って接触する、鉛直面に沿う板状部材である。支持部材１４０は、ウェブ支持部１２０のボルト孔１２１に対応する位置に、ボルト孔１４１を有する。 Furthermore, although an example in which the first member and the second member are H-section steel has been described, the present invention is not limited to this, and steel materials such as angle steel, channel steel, and square pipe having flanges may be used. For example, FIG. 3 is a diagram illustrating a coupling member 101 as a modified example. When the first member is the existing shaped steel 102 such as angle steel or channel steel, the flange 102b extends only in one direction (rightward in FIG. 2) from the lower end of the web 102c, and the flange support portion 110 Only one connecting member 101 is used because there is one object to be sandwiched between the two. In this case, it is preferable to use a support member 140 for sandwiching the web 103d together with the web support portion 120 and tightening the bolt 130 and the nut 131. FIG. The support member 140 is, for example, a plate-shaped member along a vertical plane that contacts along the surfaces of the web 102c and the web 103c of the connecting shaped steel 103. As shown in FIG. The support member 140 has bolt holes 141 at positions corresponding to the bolt holes 121 of the web support portion 120 .

さらにまた、連結Ｈ形鋼３に上端部分のフランジ３ａ、３ｂが切り欠かれ、被取付面としてのウェブ３ｄが形成される例を説明したが、フランジ３ａ、３ｂが切り欠かれていない、本来の形状のＨ形鋼を第二部材として用いてもよい。 Furthermore, an example has been described in which the flanges 3a and 3b at the upper end portion of the connecting H-section steel 3 are notched to form a web 3d as a mounting surface. You may use H-beam steel of the shape of as a 2nd member.

ここで、図４は、他の変形例としての結合部材２０１を説明する図である。図５は、図４を左方から示す図である。図６は、図４を右方から示す図である。 Here, FIG. 4 is a diagram illustrating a connecting member 201 as another modified example. FIG. 5 is a diagram showing FIG. 4 from the left. FIG. 6 is a diagram showing FIG. 4 from the right side.

連結Ｈ形鋼３のようにフランジ３ａ、３ｂを切り欠くと、少なからず強度が低下するおそれがある。これに対し、結合部材２０１は、フランジ２０３ａ、２０３ｂが切り欠かれていない連結Ｈ形鋼２０３であっても、図４から図６のように連結Ｈ形鋼２０３を既設Ｈ形鋼２０２に結合できる。一対の結合部材２０１においては、フランジ２０２ｂを支持するフランジ支持部２１０は、一対の結合部材１と同様の構成を有する。一方、ウェブ支持部２２０は、ウェブ２０２ｃの下方で一対のウェブ支持部２２０同士が空間を隔てることなく対面し、かつ右方のウェブ支持部２２０が左方のウェブ支持部２２０よりも下方に長く伸びている。 If the flanges 3a and 3b are notched like the connecting H-section steel 3, there is a risk that the strength will not be small. On the other hand, the connecting member 201 connects the connecting H-section steel 203 to the existing H-section steel 202 as shown in FIGS. can. In the pair of coupling members 201, the flange supporting portion 210 that supports the flange 202b has the same configuration as that of the pair of coupling members 1. As shown in FIG. On the other hand, the web support portions 220 face each other without a space below the web 202c, and the right web support portion 220 is longer downward than the left web support portion 220. growing.
