Description

本発明は、建築構造物や土木構造物などにおいて、構造用鋼材、コンクリート材、木材、合成樹脂材などの異種材料を一体的に接合して形成される接合構造に関する。 The present invention relates to a joining structure formed by integrally joining different materials such as structural steel, concrete, wood, and synthetic resin in a building structure or a civil engineering structure.

建築構造物や土木構造物などにおいては、構造用鋼材、コンクリート材、木材、合成樹脂材などの異種材料を組み合わせて接合した構造が施工されているが、本発明に関連する従来技術として、例えば、図３６，図３７に示す頭付きスタッド２０１を使用した複合構造２００あるいは図３８，図３９に示す接合構造３００などが知られている。 In building structures and civil engineering structures, a structure in which different materials such as structural steel, concrete, wood, and synthetic resin are combined and joined is constructed. As a conventional technique related to the present invention, for example, , A composite structure 200 using the headed stud 201 shown in FIGS. 36 and 37, or a joint structure 300 shown in FIGS. 38 and 39 is known.

図３６，図３７に示す複合構造２００においては、構造用鋼材（Ｈ形鋼）である鉄骨梁２０２の上面に複数の頭付きスタッド２０１が所定間隔ごとに起立状態で溶接され、これらの頭付きスタッド２０１及び鉄骨梁２０２の上面を埋設した状態でコンクリート材２０３が打設されている。 In the composite structure 200 shown in FIGS. 36 and 37, a plurality of headed studs 201 are welded to the upper surface of the steel beam 202, which is a structural steel material (H-shaped steel), in an upright state at predetermined intervals, and these headed studs 201 are welded. The concrete material 203 is cast with the upper surfaces of the stud 201 and the steel beam 202 buried.

また、図３８，図３９に示す接合構造３００においては、構造用鋼材（Ｈ形鋼）である鉄骨柱３０２のウェブ３０２ｗの両面及びフランジ３０２ｆの外面に、それぞれ複数の頭付きスタッド３０１が所定間隔ごとに起立状態で溶接され、鉄骨柱３０２及び頭付きスタッド３０１の周りに鉄筋３０３が配筋され、鉄骨柱３０２、複数の頭付きスタッド３０１及び鉄筋３０３を埋設した状態でコンクリート材３０４が打設されている。 Further, in the joint structure 300 shown in FIGS. 38 and 39, a plurality of headed studs 301 are spaced apart from each other on both sides of the web 302w of the steel frame column 302 which is a structural steel material (H-shaped steel) and on the outer surface of the flange 302f. Each is welded in an upright position, reinforcing bars 303 are arranged around the steel column 302 and the headed stud 301, and the concrete material 304 is placed with the steel column 302, the plurality of headed studs 301, and the reinforcing bar 303 embedded. Has been done.

一方、本発明に関連するその他の従来技術として、例えば、特許文献１，２に記載された「梁補強金具」などがある。この梁補強金具は、建築構造物を形成するＨ形鋼製の鉄骨梁のウェブに開設された配管挿通用の貫通孔の周囲に取り付けて使用するものであり、貫通孔の周囲を補強する機能を有している。 On the other hand, as another conventional technique related to the present invention, for example, there are "beam reinforcing metal fittings" described in Patent Documents 1 and 2. This beam reinforcing metal fitting is used by being attached around a through hole for pipe insertion provided in the web of an H-shaped steel beam forming a building structure, and has a function of reinforcing the circumference of the through hole. have.

図３６，図３７に示す複合構造２００や図３８，図３９に示す接合構造３００において使用されている頭付きスタッド２０１，３０１は、「柔なずれ止め」として知られており、その軸部２０１ａ，３０１ａの曲げ剛性が小さいので、鉄骨梁２０２や鉄骨柱３０２とコンクリート材２０３，３０４との間にズレを伴いながら力を伝達する特性を有している。従って、現行の設計法では、剛性不足を補うために多数の頭付きスタッド２０１，３０１を必要としている。また、頭付きスタッド２０１，３０１の最小高さは８０ｍｍ〜１００ｍｍ程度であることから、狭小な接合領域では施工が困難となる状況が生じている。 The headed studs 201 and 301 used in the composite structure 200 shown in FIGS. 36 and 37 and the joint structure 300 shown in FIGS. 38 and 39 are known as "soft slip stoppers", and the shaft portion 201a thereof. , 301a has a small bending rigidity, so that it has a characteristic of transmitting a force with a deviation between the steel beam 202 or the steel column 302 and the concrete materials 203 and 304. Therefore, the current design method requires a large number of headed studs 201 and 301 to compensate for the lack of rigidity. Further, since the minimum height of the headed studs 201 and 301 is about 80 mm to 100 mm, there is a situation in which construction becomes difficult in a narrow joint region.

一方、特許文献１，２に記載された梁補強金具は、鉄骨梁のウェブに開設された配管挿通用の貫通孔の周囲に取り付け、貫通孔の周囲を補強する機能を有するものであるが、鉄骨梁とコンクリート材との接合については、特許文献１，２には全く記載されておらず、それを示唆する記載もない。 On the other hand, the beam reinforcing metal fittings described in Patent Documents 1 and 2 have a function of being attached around a through hole for pipe insertion provided in a web of a steel frame beam to reinforce the periphery of the through hole. Patent Documents 1 and 2 do not describe the joining of the steel beam and the concrete material at all, and there is no description suggesting it.

そこで、本発明が解決しようとする課題は、狭小な接合領域においても施工可能であり、ずれ剛性と剪断耐力の増大を図ることができ、汎用性にも優れた異種材料接合構造を提供することにある。 Therefore, the problem to be solved by the present invention is to provide a dissimilar material bonding structure which can be constructed even in a narrow bonding region, can increase the displacement rigidity and the shear resistance, and has excellent versatility. It is in.

以下、図面に基づいて、本発明の実施形態である異種材料接合構造について説明する。 Hereinafter, the dissimilar material bonding structure according to the embodiment of the present invention will be described with reference to the drawings.

初めに、図１〜図３に基づいて、本発明の実施形態である異種材料接合構造を構成する剪断抵抗部材１について説明する。図１〜図３に示すように、剪断抵抗部材１は鋼板で形成されており、平板状の基板部２と、基板部２を厚さ２ｔ方向に貫通する一つの貫通孔３と、貫通孔３の内周縁から基板部２の片方の面（表面２ａ）より外側に突出する突縁部４と、を有している。 First, the shear resistance member 1 constituting the dissimilar material bonding structure according to the embodiment of the present invention will be described with reference to FIGS. 1 to 3. As shown in FIGS. 1 to 3, the shear resistance member 1 is made of a steel plate, and has a flat plate-shaped substrate portion 2, one through hole 3 penetrating the substrate portion 2 in the thickness 2t direction, and a through hole. It has a protruding edge portion 4 that protrudes outward from one surface (surface 2a) of the substrate portion 2 from the inner peripheral edge of the substrate portion 2.

剪断抵抗部材１の貫通孔３及び突縁部４は鋼板にプレス加工（バーリング加工）を施すことによって形成されているが、製造方法を限定するものではない。また、剪断抵抗部材１の基板部２の外形は四角形であり、貫通孔３は円形であるが、これらの形状に限定するものではない。 The through hole 3 and the ridge portion 4 of the shear resistance member 1 are formed by pressing (burring) a steel plate, but the manufacturing method is not limited. Further, the outer shape of the substrate portion 2 of the shear resistance member 1 is quadrangular, and the through hole 3 is circular, but the shape is not limited to these.

次に、図４〜図６に基づいて、図１に示す剪断抵抗部材１を構造用鋼材５に固着する形態について説明する。図４，図５に示すように、構造用鋼材５の平板部分の外面５ａに対し、剪断抵抗部材１の基板部２の裏面２ｂを接触させ、基板部２の外周と構造用鋼材５の外面５ａとの間に溶接Ｗを施すことにより、両者を固着している。 Next, a mode in which the shear resistance member 1 shown in FIG. 1 is fixed to the structural steel material 5 will be described with reference to FIGS. 4 to 6. As shown in FIGS. 4 and 5, the back surface 2b of the substrate portion 2 of the shear resistance member 1 is brought into contact with the outer surface 5a of the flat plate portion of the structural steel material 5, and the outer circumference of the substrate portion 2 and the outer surface of the structural steel material 5 are brought into contact with each other. By performing welding W between 5a and 5a, both are fixed.

図５に示す形態おいては、構造用鋼材５の平板部分に加工を施すことなく剪断抵抗部材１を溶接Ｗによって固着しているが、これに限定するものではないので、図６に示すように、構造用鋼材５において剪断抵抗部材１の貫通孔３と対向する領域に、構造用鋼材５を厚さ５ｔ方向に貫通する円形の開口部６を設け、剪断抵抗部材１の貫通孔３を構造用鋼材５の開口部６に対向させた状態で両者を固着することもできる。 In the form shown in FIG. 5, the shear resistance member 1 is fixed by welding W without processing the flat plate portion of the structural steel material 5, but the present invention is not limited to this, and is shown in FIG. In the structural steel material 5, a circular opening 6 that penetrates the structural steel material 5 in the thickness 5t direction is provided in a region facing the through hole 3 of the shear resistance member 1, and the through hole 3 of the shear resistance member 1 is provided. Both can be fixed in a state of facing the opening 6 of the structural steel material 5.

図６に示す形態においては、剪断抵抗部材１の貫通孔３の軸心３ｃと、構造用鋼材５の開口部６の軸心６ｃとを一致させた状態で剪断抵抗部材１を構造用鋼材５に固着しているが、これに限定するものではない。 In the form shown in FIG. 6, the shear resistance member 1 is used as the structural steel material 5 in a state where the axis 3c of the through hole 3 of the shear resistance member 1 and the axis 6c of the opening 6 of the structural steel material 5 are aligned with each other. It is stuck to, but it is not limited to this.

次に、図７，図８に基づいて、本発明の実施形態である異種材料接合構造１００について説明する。図７は本発明の実施形態である異種材料接合構造１００を示す一部省略断面図であり、図８は図７中の矢線Ｄで示す部分を、コンクリート材１３を省略した状態で示す拡大断面図である。 Next, the dissimilar material bonding structure 100, which is an embodiment of the present invention, will be described with reference to FIGS. 7 and 8. FIG. 7 is a partially omitted cross-sectional view showing a dissimilar material bonding structure 100 according to an embodiment of the present invention, and FIG. 8 is an enlarged view showing a portion indicated by an arrow D in FIG. 7 with the concrete material 13 omitted. It is a sectional view.

図７に示すように、異種材料接合構造１００は、構造用鋼材の一種であるＨ形鋼１１と、Ｈ形鋼１１のウェブ１１ａの外面に固着された複数の剪断抵抗部材１，１と、Ｈ形鋼１１の周りに配筋された鉄筋１２及び剪断抵抗部材１，１を内包するように打設されたコンクリート材１３と、を備えている。 As shown in FIG. 7, the dissimilar material joint structure 100 includes an H-shaped steel 11 which is a kind of structural steel material, and a plurality of shear resistance members 1 and 1 fixed to the outer surface of the web 11a of the H-shaped steel 11. It includes a reinforcing bar 12 arranged around the H-shaped steel 11 and a concrete material 13 cast so as to include the shear resistance members 1 and 1.

複数の剪断抵抗部材１，１は何れも図１〜図３に示す剪断抵抗部材１と同じであり、図８に示すように、それぞれの基板部２の外周とＨ形鋼１１のウェブ１１ａの外面との間に溶接Ｗを施すことにより、剪断抵抗部材１，１がＨ形鋼１１に固着されている。 The plurality of shear resistance members 1 and 1 are all the same as the shear resistance members 1 shown in FIGS. 1 to 3, and as shown in FIG. 8, the outer periphery of each substrate portion 2 and the web 11a of the H-shaped steel 11 The shear resistance members 1 and 1 are fixed to the H-shaped steel 11 by performing welding W between the outer surface and the outer surface.

図８に示すように、異種材料接合構造１００においては、一対の剪断抵抗部材１，１が、Ｈ形鋼１１のウェブ１１ａを挟んで互いに鏡面対称を成す状態に固着されている。また、ウェブ１１ａにおいて剪断抵抗部材１，１の貫通孔３，３が対向する領域には、貫通孔３，３と同軸上で連通する円形の開口部６が開設されている。Ｈ形鋼１１、鉄筋１２及び剪断抵抗部材１，１を内包するように打設されたコンクリート材１３（図７参照）は、貫通孔３，３及び開口部６の内部にも隙間なく充填されている。 As shown in FIG. 8, in the dissimilar material joining structure 100, the pair of shear resistance members 1 and 1 are fixed in a state of being mirror-symmetrical to each other with the web 11a of the H-shaped steel 11 interposed therebetween. Further, in the region of the web 11a where the through holes 3 and 3 of the shear resistance members 1 and 1 face each other, a circular opening 6 communicating coaxially with the through holes 3 and 3 is provided. The concrete material 13 (see FIG. 7) cast so as to include the H-shaped steel 11, the reinforcing bar 12, and the shear resistance members 1 and 1 is also filled inside the through holes 3 and 3 and the opening 6 without gaps. ing.

図７に示す異種材料接合構造１００において、Ｈ形鋼１１のウェブ１１ａを挟持するように固着された剪断抵抗部材１，１はＨ形鋼１１と一体化しており、剪断抵抗部材１，１の突縁部４，４はそれぞれウェブ１１ａの面方向に加わる剪断力に対して強い支圧抵抗力を発揮するので、図３８，図３９に示す従来の接合構造３００に比べ、ずれ剛性及び剪断耐力が大幅に増大する。 In the dissimilar material joining structure 100 shown in FIG. 7, the shear resistance members 1 and 1 fixed so as to sandwich the web 11a of the H-shaped steel 11 are integrated with the H-shaped steel 11, and the shear resistance members 1 and 1 are integrated. Since the ridges 4 and 4 each exhibit a strong bearing resistance against the shearing force applied in the plane direction of the web 11a, the displacement rigidity and the shearing resistance are higher than those of the conventional joint structure 300 shown in FIGS. 38 and 39. Will increase significantly.

また、図３８，図３９に示す従来の接合構造３００において使用されている頭付きスタッド３０１の全長３０１ｔに比べると、剪断抵抗部材１全体の厚さ１ｔ（図２参照）が小さいので、異種材料接合構造１００は狭小な接合領域においても施工可能である。さらに、後述するように、剪断抵抗部材１は様々な形状の構造用鋼材に対して様々な状態に固着することができるので、多種多様な施工条件に的確に対応することが可能であり、汎用性にも優れている。 Further, as compared with the total length 301t of the headed stud 301 used in the conventional joint structure 300 shown in FIGS. 38 and 39, the thickness of the entire shear resistance member 1 is 1t (see FIG. 2), so that different materials are used. The joint structure 100 can be constructed even in a narrow joint region. Further, as will be described later, since the shear resistance member 1 can be fixed to various shapes of structural steel materials in various states, it is possible to accurately cope with a wide variety of construction conditions, and it is versatile. It is also excellent in sex.

次に、図９〜図３２に基づいて、本発明のその他の実施形態である異種材料接合構造１０１〜１２０について説明する。なお、図９〜図３２に示す異種材料接合構造１０１〜１２０において、図７，図８に示す異種材料接合構造１００の構成部分と共通する部分については、図７，図８中の符号と同符号を付して説明を省略する。また、図９〜図３２に示す異種材料接合構造１０１〜１２０においては、剪断抵抗部材及び構造用鋼材などの周りに打設されるコンクリート材や鉄筋を省略している。 Next, dissimilar material bonding structures 101 to 120, which are other embodiments of the present invention, will be described with reference to FIGS. 9 to 32. In the dissimilar material joining structures 101 to 120 shown in FIGS. 9 to 32, the parts common to the constituent parts of the dissimilar material joining structures 100 shown in FIGS. 7 and 8 are the same as the reference numerals in FIGS. 7 and 8.

剪断抵抗部材２６の基板部２７は、その表面２７ａ（突縁部２９がある面）側を凸とする湾曲形状をなしており、構造用鋼材５の外面５ａに対し、凹状をなす裏面２７ｂ（突縁部２９が無い面）を対向させた状態で溶接Ｗによって固着されている。コンクリート材（図示せず）は、貫通孔２８を貫通した状態で構造用鋼材５と剪断抵抗部材２６との間にも打設されている。打設されたコンクリート材（図示せず）は、構造用鋼材５の外面５ａと、剪断抵抗部材２６の基板部２７の裏面２７ｂとの間にも流れ込んだ状態となるので、構造用鋼材５の外面５ａからコンクリート材が浮き上がる方向に生じる剥離力（乖離力、浮上力）に対して、剪断抵抗部材２６全体で抵抗し、一体化を図ることができる。 The substrate portion 27 of the shear resistance member 26 has a curved shape in which the surface 27a (the surface where the ridge portion 29 is located) is convex, and the back surface 27b (concave) with respect to the outer surface 5a of the structural steel material 5. It is fixed by welding W in a state where the surface without the butt portion 29) is opposed to each other. A concrete material (not shown) is also cast between the structural steel material 5 and the shear resistance member 26 in a state of penetrating the through hole 28. The cast concrete material (not shown) also flows between the outer surface 5a of the structural steel material 5 and the back surface 27b of the substrate portion 27 of the shear resistance member 26. The entire shear resistance member 26 can resist the peeling force (dissociation force, levitation force) generated in the direction in which the concrete material is lifted from the outer surface 5a, and can be integrated.

また、図２８，図２９に示す異種材料接合構造１１８において、剪断抵抗部材２６の貫通孔２８は、コンクリート材の充填性（一体化性）の向上に有効であり、突縁部２９内に打設されたコンクリート材は、突縁部２９の剛性向上に有効である。さらに、突縁部２９は、構造用鋼材５とコンクリート材との界面に生じる水平剪断力（構造用鋼材５の面方向の剪断力）に対して抵抗力を発揮し、基板部２７の凹状に湾曲した裏面２７ｂは、構造用鋼材５とコンクリート材との界面に生じる剥離力（垂直力）に対する抵抗力を発揮する。 Further, in the dissimilar material joining structure 118 shown in FIGS. 28 and 29, the through hole 28 of the shear resistance member 26 is effective in improving the filling property (integration) of the concrete material, and is struck in the ridge portion 29. The provided concrete material is effective in improving the rigidity of the ridge portion 29. Further, the ridge portion 29 exerts a resistance against the horizontal shearing force (shearing force in the surface direction of the structural steel material 5) generated at the interface between the structural steel material 5 and the concrete material, and forms a concave shape of the substrate portion 27. The curved back surface 27b exerts a resistance force against a peeling force (normal force) generated at the interface between the structural steel material 5 and the concrete material.

このように、図２８，図２９に示す異種材料接合構造１１８においては、湾曲形状の基板部２７を有する剪断抵抗部材２６の存在により、構造用鋼材５とコンクリート材とが強固に一体化されるため、ずれ剛性及び剪断抵抗力の向上を図ることができる。 As described above, in the dissimilar material joining structure 118 shown in FIGS. 28 and 29, the structural steel material 5 and the concrete material are firmly integrated by the presence of the shear resistance member 26 having the curved substrate portion 27. Therefore, the displacement rigidity and the shear resistance can be improved.

It is fixed by welding W with the surface on which the butt portion 33 is located facing each other. A concrete material (not shown) is also cast between the structural steel material 5 and the shear resistance member 30 in a state of penetrating the through hole 32.
