Description

本発明は、比較的小断面の構造材同士を組み合わせて一体化した組合せ構造材に関する。   The present invention relates to a combined structural material obtained by combining structural materials having relatively small cross sections.

従来より、比較的小断面の部材を組み合わせて、力学的に一体化した組合せ構造材が知られている。   2. Description of the Related Art Conventionally, a combination structural material is known in which members having relatively small cross sections are combined and mechanically integrated.

このような組合せ構造材は、主に木材に対して多く見られる。例えば、下記特許文献1では、一辺120mmの方角材の側面に、長尺のボルトが貫通する孔を設け、方角材を左右側面同士を突き合わせ、方角材の対角線方向の両側角部に一対のL字形の角材緊締用金具を当てて、これらを1本の貫通ボルトにより締結固定することにより一体化した組合せ構造材が提案されている。   Such a combination structural material is often found mainly on wood. For example, in Patent Document 1 below, a hole through which a long bolt penetrates is provided on the side surface of a 120 mm side material, the left and right side surfaces of the direction material are abutted with each other, and a pair of L is formed at both side corners in the diagonal direction of the direction material. A combined structural material has been proposed in which a square-shaped square member fastening metal fitting is applied and these are fastened and fixed by a single through bolt.

また、下記特許文献2では、重ね合わされた角材をねじ締結して一体化した角材組合わせ構造材であって、前記各角材は芯持ち材であり、その年輪を横切る方向に延びて重ね合わせ角材を固縛する締結ねじのための取付孔が形成され、重ね合わせ面には角材の長手方向に直交して延びる半円形溝が形成され、該半円形溝を対面させることにより生じる円筒孔に、該円筒孔の直径より大きい径を有するメタルピンが嵌着され、重ね合わせ面を密着させたときメタルピンが木面表層を圧縮し、前記円筒孔の周縁に緻密層が形成されている角材組合わせ構造材が提案されている。

Further, in Patent Document 2 below, a square member combination structure material in which stacked square members are integrated by screw fastening, and each of the square members is a core-supporting member, and extends in a direction crossing the annual ring and overlapped square members. A mounting hole for a fastening screw is formed, a semicircular groove extending perpendicularly to the longitudinal direction of the square member is formed on the overlapping surface, and a cylindrical hole generated by facing the semicircular groove A square member combination structure in which a metal pin having a diameter larger than the diameter of the cylindrical hole is fitted, and the metal pin compresses the surface layer of the wood surface when the overlapping surfaces are brought into close contact with each other, and a dense layer is formed at the periphery of the cylindrical hole Materials have been proposed.

前記特許文献1に係る組合せ構造材の場合は、L字形の角材緊締用金具が外部に露出しているため、著しく外観を損なうなどの問題があるとともに、梁材として使用する場合は、木材に空けたボルト孔の遊間やボルトに作用する支圧応力が過大となって孔に変形が起こり、木材同士の合わせ面で滑りを起こす可能性があるため、少なくとも重ね梁としての強度は有するとしても、曲げに対して一体的に抵抗する組合せ構造材とは成り難い、更には組合せ構造材を組み立てるのに多くの手間と時間を要するなどの問題があった。   In the case of the combined structural material according to Patent Document 1, since the L-shaped square member fastening bracket is exposed to the outside, there is a problem that the appearance is remarkably deteriorated. Even if there is at least the strength of a laminated beam, there is a possibility that the bearing stress acting on the bolt and the gap between the vacant bolt holes will be excessive and the holes will be deformed and slip on the mating surfaces of the wood. However, there is a problem that it is difficult to be a combined structural material that integrally resists bending, and further, it takes a lot of labor and time to assemble the combined structural material.

上記特許文献2に係る角材組合せ構造材の場合は、メタルピンを重ね合わせ面に設けることにより、角材同士のズレを防止し得るようになるが、組合せ構造材に組み立てるのに多くの手間と時間を要するなどの問題が依然として解決されていない。   In the case of the square member combination structure material according to Patent Document 2 described above, it is possible to prevent misalignment between the square members by providing the metal pins on the overlapping surface, but it takes a lot of time and effort to assemble the combination structure material. The problem of needing is still not solved.

一方で、前記組合せ構造材は、大きな断面の部材を得難い木材に対する適用が主であり、鋼材の場合は、各種断面の構造材が予め用意されていることが多いため、鋼材を対象とした組合せ構造はあまり提案されていない。通常は、ボルト・ナットによる一体化が一般的であると思われる。   On the other hand, the combination structural material is mainly applied to wood in which it is difficult to obtain a member having a large cross section, and in the case of a steel material, a structural material having various cross sections is often prepared in advance. No structure has been proposed. Usually, bolt and nut integration seems to be common.

そこで本発明の主たる課題は、比較的小断面の構造材同士を組み合わせて一体化した組合せ構造材において、外観が良好であるとともに、簡単に構造材同士を一体化でき、部材の合わせ面におけるスリップ(滑り)を確実に防止し得るようにすることにある。   Therefore, the main problem of the present invention is that a combination structural material in which structural materials having relatively small cross sections are combined and integrated has a good appearance and can be easily integrated with each other, and slip on the mating surfaces of the members. (Slipping) is to be surely prevented.

前記課題を解決するために請求項1に係る本発明として、構造材同士を、少なくとも1面において部材長手方向に沿って面接触させ、その接触面において一体化を図った組合せ構造材であって、
組み合わされた一方側構造材に、部材長手方向に適宜の間隔で、幅方向に沿って深部側が幅広形状となる断面形状で凹状部を形成するとともに、他方側構造材に、前記凹状部に対応する部位に対し、幅方向に沿って前記凹状部に整合する断面形状で凸状部を形成し、
接触面において、前記一方側構造材の凹状部と前記他方側構造材の凸状部とが嵌合によって接合され、前記構造材同士が一体化されていることを特徴とする組合せ構造材が提供される。
In order to solve the above-mentioned problem, the present invention according to claim 1 is a combined structural material in which structural materials are brought into surface contact with each other along the longitudinal direction of the member on at least one surface, and the contact surfaces are integrated. ,
In the combined one side structural material, a concave portion is formed in a cross-sectional shape in which the deep side is wide along the width direction at an appropriate interval in the longitudinal direction of the member, and the other side structural material corresponds to the concave portion. For the part to be formed, a convex part is formed with a cross-sectional shape that matches the concave part along the width direction,

従って、外観的には単に各構造材同士が組み合わされた状態であるため、外観が良好であるとともに、各構造材同士を工場又は現場においても簡単に一体化することができる。また、接合面では凹状部と凸状部との嵌合によって部材の合わせ面におけるスリップ(滑り)を確実に防止することが可能となる。   Therefore, since the appearance is simply a state where the structural materials are combined with each other, the appearance is good and the structural materials can be easily integrated in the factory or on-site. In addition, it is possible to reliably prevent slippage (slip) on the mating surface of the members by fitting the concave portion and the convex portion at the joint surface.

請求項2に係る本発明として、前記凹状部の断面形状は台形とされる請求項1記載の組合せ構造材が提供される。   As a second aspect of the present invention, there is provided the combination structural member according to the first aspect, wherein a cross-sectional shape of the concave portion is a trapezoid.

上記請求項2記載の発明は、好適な凹状部の断面形状を規定したものである。確実な抜止めを図り得る点で、構造材に形成される前記凹状部の断面形状は、台形とするのが望ましい。   The invention according to the second aspect defines a preferable cross-sectional shape of the concave portion. It is desirable that the cross-sectional shape of the concave portion formed in the structural material is a trapezoid because it can be surely secured.

請求項3に係る本発明として、前記凸状部は、構造材本体を切削することにより形成してある請求項1,2いずれかに記載の組合せ構造材が提供される。   As a third aspect of the present invention, there is provided the combined structural material according to any one of the first and second aspects, wherein the convex portion is formed by cutting a structural material main body.

上記請求項3記載の発明は、前記凸状部を構造材本体を切削することにより形成するものである。組み合わせる構造材として、同一断面の部材を使用する場合は、凸状部は該凸状部以外の構造材本体を切削することによって形成するのが効率的である。   In the invention according to the third aspect, the convex portion is formed by cutting a structural material body. When members having the same cross section are used as the structural material to be combined, it is efficient to form the convex portion by cutting the structural material main body other than the convex portion.

請求項4に係る本発明として、前記構造材は、鋼またはアルミニウム合金である請求項1〜3いずれかに記載の組合せ構造材が提供される。   According to a fourth aspect of the present invention, there is provided the combined structural material according to any one of the first to third aspects, wherein the structural material is steel or an aluminum alloy.

上記請求項4記載の発明は、構造材として好適な素材を規定したものである。本発明は、木材に対しても適用が可能であるが、好ましくは鋼またはアルミニウム合金に対して適用される。近年は、リサイクル性と加工性に優れたアルミニウム合金が、環境負荷の総合的な削減の一翼を担う素材として脚光を浴び始めており、アルミニウム合金を建築構造に使用できる法整備が2000年6月に行われ、戸建て住宅や低層建築物などへの適用実績も増えつつある。   The invention according to claim 4 defines a material suitable as a structural material. Although the present invention can be applied to wood, it is preferably applied to steel or aluminum alloy.

上記請求項5記載の発明は、本発明の組合せ構造材を梁部材として使用する場合の好適例を示したものである。すなわち、梁部材として使用する場合は、2つの構造材を上下段で接合し、一体化した構造とするのが望ましい。この場合は、重ね合わせ面が高さ方向の中央となるため、この位置では曲げモーメントによる引張力や圧縮力が作用しない。従って、構造材に形成した凹状部(断面欠損)が構造的弱点とならずに済むようになる。   The invention according to claim 5 shows a preferred example in the case where the combined structural material of the present invention is used as a beam member. That is, when used as a beam member, it is desirable that two structural members are joined at the upper and lower stages to form an integrated structure. In this case, since the overlapping surface is the center in the height direction, no tensile force or compressive force due to a bending moment acts at this position. Therefore, the concave portion (cross-sectional defect) formed in the structural material does not become a structural weak point.

請求項6に係る本発明として、前記組合せ構造材は柱部材とされ、4つの構造材がそれぞれ、隣接する構造材と直交する2面で接合され、一体化されている請求項1〜4いずれかに記載の組合せ構造材が提供される。   As the present invention according to claim 6, the combination structural material is a pillar member, and each of the four structural materials is joined and integrated on two surfaces orthogonal to the adjacent structural material. A combined structural material as described above is provided.

上記請求項6記載の発明は、本発明の組合せ構造材を柱部材として使用する場合の好適例を示したものである。すなわち、柱部材として使用する場合は、4つの構造材を用い、それぞれの構造材が隣接する構造材と直交する2面で接合され、一体化されている構造とするのが望ましい。各構造材同士が2つの直交面で隣接する構造材と一体化されていることにより、座屈強度にも優れ、高い圧縮強度特性を持つようになる。   The invention described in claim 6 shows a preferred example in the case where the combined structural material of the present invention is used as a column member. That is, when used as a pillar member, it is desirable to use a structure in which four structural materials are used, and each structural material is joined and integrated on two surfaces orthogonal to adjacent structural materials. Since each structural material is integrated with a structural material adjacent to each other at two orthogonal planes, the structural material is excellent in buckling strength and has high compressive strength characteristics.

以上詳説のとおり本発明によれば、外観が良好であるとともに、簡単に構造材同士を一体化でき、部材の合わせ面におけるスリップ(滑り)を確実に防止し得る組合せ構造材を得ることができる。   As described above in detail, according to the present invention, it is possible to obtain a combined structural material that has a good external appearance, can easily integrate the structural materials, and can reliably prevent slippage at the mating surfaces of the members. .

以下、本発明の実施の形態について図面を参照しながら詳述する。

図1は本発明に係る組合せ構造材1の組み立て要領を示す斜視図であり、図2は組合せ構造材1の断面図、図3はその側面図である。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[First embodiment]
FIG. 1 is a perspective view showing the assembly procedure of the combination structural member 1 according to the present invention, FIG. 2 is a sectional view of the combination structural member 1, and FIG. 3 is a side view thereof.

組合せ構造材1は、構造材同士を、少なくとも1面において部材長手方向に沿って面接触させ、その接触面において一体化を図ったものである。具体的には、図1に示されるように、各構造材2,3の接触面において、一方側構造材2に、部材長手方向に適宜の間隔で、幅方向に沿って深部側が幅広形状となる断面形状で凹状部4、4…を形成するとともに、他方側構造材3に、前記凹状部4,4…に対応する部位に対し、幅方向に沿って前記凹状部4に整合する断面形状で凸状部5,5…を形成する。そして、構造材2,3の内の一方又は両方を側方側から、一方側構造材2の凹状部4,4…と、他方側構造材3の凸状部5,5…とを嵌合させるようにスライドさせ、接触面同士を接合することによって前記構造材2,3同士を一体化する。   The combined structural material 1 is obtained by bringing the structural materials into surface contact along the longitudinal direction of the member on at least one surface and integrating the contact surfaces. Specifically, as shown in FIG. 1, on the contact surface of each structural material 2, 3, the one-side structural material 2 has a wide shape along the width direction at an appropriate interval in the longitudinal direction of the member. Are formed in a cross-sectional shape, and the other side structural member 3 is aligned with the concave portion 4 along the width direction with respect to a portion corresponding to the concave portions 4, 4. To form the convex portions 5, 5. Then, one or both of the structural members 2 and 3 are fitted from the side to the concave portions 4, 4... Of the one-side structural member 2 and the convex portions 5, 5. The structural members 2 and 3 are integrated by sliding them so that the contact surfaces are joined together.

以下、さらに具体的に詳述する。   This will be described in more detail below.

図示された上段側の構造材2は、上フランジ2aと、下フランジ2bと、これら上下フランジ2a、2bを繋ぐとともに、離間をおいて配設された2つのウェブ2c、2dとによって縦長の中空部2eが形成された中空H形断面部材である。下段側の構造材3も同様である。   The upper structural member 2 shown in the figure has an upper flange 2a, a lower flange 2b, and a vertically long hollow formed by two webs 2c and 2d that connect the upper and lower flanges 2a and 2b and are spaced apart from each other. This is a hollow H-shaped cross-section member in which a portion 2e is formed. The same applies to the structural material 3 on the lower side.

前記上段側構造材2の下フランジ2bの下面には、部材長手方向に適宜の間隔で、幅方向に沿って深部側が幅広形状となる断面形状、具体的には台形状の凹状部4、4…が形成されている。また、前記下段側構造材3の上フランジ3aの上面には、前記凹状部4,4…に対応する部位に対し、幅方向に沿って前記凹状部4に整合する断面形状で凸状部5,5…が形成されている。前記凸状部5,5…は、上段側構造材2と下段側構造材3とが同一断面の部材が使用されているため、構造材本体を切削することによって形成されている。   On the lower surface of the lower flange 2b of the upper structural member 2, a cross-sectional shape in which the deep side is wide along the width direction at an appropriate interval in the longitudinal direction of the member, specifically, trapezoidal concave portions 4, 4 ... is formed. Further, on the upper surface of the upper flange 3a of the lower structural member 3, the convex portion 5 has a cross-sectional shape that matches the concave portion 4 along the width direction with respect to the portion corresponding to the concave portions 4, 4,. , 5... Are formed. The convex portions 5, 5... Are formed by cutting the structural material main body because the upper structural member 2 and the lower structural member 3 are members having the same cross section.

前記上段側構造材2の凹状部4,4…と、下段側構造材3の凸状部5,5…とが整合することにより、結果的に前記凹状部4,4…の間に形成されている凸状部分4aと、前記凸状部5,5…の間に形成されている凹状部分5aとが整合することになり、互い違いに噛合する接合面を形成するようになっている。   The concave portions 4, 4,... Of the upper structural member 2 and the convex portions 5, 5,... Of the lower structural member 3 are aligned with each other, resulting in formation between the concave portions 4, 4,. The convex portions 4a and the concave portions 5a formed between the convex portions 5, 5,... Are aligned to form joint surfaces that mesh alternately.

前記凹状部及び凸状部4,5の形状としては、台形状以外に、小判形状、楕円形状、多角形状等とすることもできるが、せん断抵抗面積を大きく確保できる点で台形とするのが望ましい。   In addition to the trapezoidal shape, the concave portion and the convex portions 4 and 5 may be oval, elliptical, polygonal, etc., but the trapezoid is preferable in that a large shear resistance area can be secured. desirable.

前記構造材2,3としては、鋼材はもちろんの事、アルミニウム合金によって製造された形材とすることができる。   As the structural materials 2 and 3, not only steel materials but also shapes made of aluminum alloys can be used.

組立は、同図1に示されるように、構造材2及び構造材3の内の一方又は両方を、図示例では構造材3側を側方から水平方向に移動させ、構造材2の下フランジ2bに形成された凹状部4,4…と、構造材3の上フランジ3aに形成された凸状部5,5…とを嵌合によって接合し、一体化を図る。   As shown in FIG. 1, the assembly is performed by moving one or both of the structural material 2 and the structural material 3 horizontally in the illustrated example from the side of the structural material 3, and lower flanges of the structural material 2. The concave portions 4, 4... Formed in 2 b and the convex portions 5, 5.

上記組合せ構造材1は、梁部材としての使用を想定したものである。2つの構造材2,3を上下段で接合し、一体化した場合は、図4に示されるように、合わせ面が高さ方向の中央となるため、この位置では曲げモーメントによる引張力や圧縮力が作用しない。従って、構造材2,3に形成した凹状部4…および凸状部5、5の間の凹状部分5a(断面欠損部)が構造的弱点とならずに済むようになる。なお、図中、(+)は圧縮状態を示し、(-)は引張り状態を示す。   The combination structural material 1 is assumed to be used as a beam member. When the two structural members 2 and 3 are joined together at the upper and lower stages and integrated, as shown in FIG. 4, the mating surface is the center in the height direction. Power does not work. Accordingly, the concave portions 4a formed in the structural members 2 and 3 and the concave portions 5a (cross-sectionally missing portions) between the convex portions 5 and 5 do not become structural weak points. In the figure, (+) indicates a compressed state, and (-) indicates a tensile state.

ところで、上記形態例では、前記構造材2,3の断面形状を中空H形断面としたが、種々の断面形状とすることが可能である。その他の具体例を図5に示す。図5(A)は構造材2,3を中空矩形断面とした例であり、図5(B)(C)は構造材2,3を中空台形断面とした例であり、図5(D)は構造材2,3を中空半円断面とした例であり、図5(E)は、構造材2,3を溝型鋼を背面合わせでボルト・ナットで一体化し断面H形状とした例であり、図5(F)は溝型鋼を背面合わせとし、連結部材6で一体化し断面H形状とした例であり、更に図5(G)は上下のフランジ幅を異ならせた断面H形状とした例である。   By the way, in the said example of embodiment, although the cross-sectional shape of the said structural materials 2 and 3 was made into the hollow H-shaped cross section, it can be set as various cross-sectional shapes. Another specific example is shown in FIG. 5A is an example in which the structural materials 2 and 3 have a hollow rectangular cross section, and FIGS. 5B and 5C are examples in which the structural materials 2 and 3 have a hollow trapezoidal cross section. FIG. Fig. 5 (E) is an example in which the structural members 2 and 3 are integrated with the bolts and nuts by back-to-back bonding with bolts and nuts. Fig. 5 (F) is an example in which the grooved steel is back-to-back and integrated with the connecting member 6 to form an H shape in cross section. Fig. 5 (G) is an example in which the upper and lower flange widths are made to have different H shapes. It is.

いずれの場合も、上下段で重ね合わせた構造材2,3を、その合わせ面において、構造材同士2、3に形成された凹状部4,4…と、凸状部5,5…とを嵌合させることによって前記構造材同士2,3を一体化する。   In any case, the structural members 2 and 3 superposed on the upper and lower tiers, on the mating surface, the concave portions 4, 4... Formed on the structural members 2 and 3, and the convex portions 5, 5. The structural members 2 and 3 are integrated by fitting.
