The structure of the building that is supported by is known. (For example, see Patent Document 1)
JP 2000-328653 A

しかしながら、上記構造では上弦材と下弦材の間に一対の斜材を交差するように設置して、一端を上弦材に、他端を下弦材に接合固定しなければならないため、作業が非常に面倒で、多くの労力と時間を要するため設置費用が嵩み、且つ、斜材による上弦材及び下弦材の両端支持では、中間部の支持力が不足して上弦材及び下弦材に中垂れ等の変形を生じ易い問題点がある。   However, in the above structure, it is necessary to install a pair of diagonal materials between the upper chord material and the lower chord material so that one end is joined to the upper chord material and the other end is joined and fixed to the lower chord material. It is cumbersome and requires a lot of labor and time, so the installation cost is high, and both ends of the upper chord and lower chord materials with diagonal materials are not supported in the middle part, so that the upper chord material and the lower chord material hang down. There is a problem that the deformation is likely to occur.

本発明は上記問題点を解消し、継手部材を嵌合するだけで同一形状の上下の分割ビーム材を一体結合して、強固で変形を生ずる虞がない大型の複合ビームを僅かの労力と時間で設置できるようにすることをその課題としている。   The present invention solves the above-mentioned problems, and by combining the upper and lower split beam members with the same shape by simply fitting the joint members, a large composite beam that is strong and does not cause deformation is slightly labor and time-consuming. The challenge is to make it possible to install in

前記課題を解決するため、請求項１に係る発明は、２つに分割形成された上分割ビーム材と、下分割ビーム材を各々に設けた継手部材を嵌合することで一体結合する複合ビームであって、上記各分割ビーム材は、接合側の端板に軸線方向へ平行に突出する複数の突片を反転させて突き合わせると、互いに嵌り合う関係位置で配置された継手部材をそれぞれ設けられ、これら継手部材を互いに嵌合させて、これに伴い重合した両分割ビーム材の突片を止め部材で接合すると、上下の分割ビーム材が面一をなすように結合されることを特徴とする。   In order to solve the above-mentioned problem, the invention according to claim 1 is a composite beam that is integrally coupled by fitting an upper divided beam material divided into two and a joint member each provided with a lower divided beam material. Each of the split beam members is provided with a joint member arranged at a relational position where the plurality of projecting pieces projecting in parallel in the axial direction are reversed and faced to the end plate on the joining side. When these joint members are fitted to each other and the projecting pieces of the two split beam members that are superposed together are joined by a stopper member, the upper and lower split beam members are joined so as to be flush with each other. To do.

請求項２に係る発明は、上記継手部材を形成する複数の突片が、一方は分割ビーム材の一方の壁と連続するように、他方を分割ビーム材の他方の壁に内接するよう設けられるとともに、一方の突片の近くには、該突片とで嵌合される相手突片の挟み込みを行う小突片が設けられていることを特徴とする。   The invention according to claim 2 is provided such that the plurality of projecting pieces forming the joint member are inscribed in the other wall of the split beam member so that one of them is continuous with the one wall of the split beam member. In addition, a small projecting piece is provided near one of the projecting pieces to sandwich the mating projecting piece fitted with the projecting piece.

請求項３に係る発明は、上記他方の突片又は小突片の相対する面の一方に、突片の嵌合に伴いこれへ対応する一方の突片側へ寄せさせる斜面が形成されていることを特徴とする。   In the invention according to claim 3, an inclined surface is formed on one of the opposing surfaces of the other projecting piece or the small projecting piece so as to move toward the one projecting piece side corresponding to the fitting of the projecting piece. It is characterized by.

請求項４に係る発明は、２つに分割形成された上分割ビーム材と、下分割ビーム材の間に中間分割ビーム材を挟んで、各々に設けた継手部材を嵌合することで一体結合する複合ビームであって、上下の分割ビーム材は、接合端に請求項１と同様に複数の突片が配置された継手部材をそれぞれ設けられ、中間分割ビーム材は、上側と下側の接合端に複数の突片の配置が反対となるようにした継手部材を設けられて、中間分割ビーム材の上側の継手部材に上分割ビーム材の継手部材を嵌合し、中間分割ビーム材の下側の継手部材に下分割ビーム材の継手部材を嵌合して、これに伴い重合した上分割ビーム材の突片と中間分割ビーム材の突片、及び下分割ビーム材の突片と中間分割ビーム材の突片を止め部材で接合すると、複数のビーム材の面一をなす結合が行われるようにしたことを特徴とする。   In the invention according to claim 4, the upper divided beam material divided into two and the lower divided beam material are sandwiched between the intermediate divided beam materials, and the joint members provided in each are fitted together. The upper and lower split beam members are each provided with a joint member having a plurality of projecting pieces arranged at the joint ends as in the first aspect, and the intermediate split beam member is joined to the upper and lower joints. A joint member is provided at the end so that the arrangement of the plurality of projecting pieces is opposite. The joint member of the upper split beam member is fitted to the upper joint member of the intermediate split beam member, and the lower part of the intermediate split beam member is fitted. The joint member of the lower split beam member is fitted to the joint member on the side, and the upper split beam member projecting piece and the intermediate split beam member projecting piece, and the lower split beam member projecting piece and the intermediate split member, which are superposed with the fitting member. When the projecting pieces of the beam material are joined with a stopper, Characterized in that to join is to be made.

請求項１に係る発明によれば、上下に分割することで小型化した分割ビーム材に設ける継手部材を、反転させると互いに嵌り合う配置の突片で形成するから、上下の分割ビーム材を１つの小さな押出機と押出ダイスで成形することができて、製作コストの大幅な低減が図れる。   According to the first aspect of the present invention, since the joint member provided on the split beam material that has been reduced in size by being split up and down is formed by the projecting pieces that are fitted to each other when inverted, the upper and lower split beam materials are 1 It can be molded with two small extruders and extrusion dies, and the production cost can be greatly reduced.

また、軸線方向へ平行に突出する複数の突片で形成される継手部材は、突き合わせるだけで簡単に接合されて、これに伴い重合した両ビーム材の突片を止め部材で接合する操作を含めても大幅な作業の省力化と時間の短縮が図れる。   In addition, a joint member formed by a plurality of projecting pieces projecting in parallel in the axial direction is simply joined by just abutting, and the operation of joining the projecting pieces of both beam members with a stop member in accordance with this is performed. Even if it is included, the labor can be saved greatly and the time can be shortened.

また、上下の分割ビーム材のウエブ板全体を継手部材で結合するから、各部の支持力が平均して中垂れ等の変形を防止するのに有効である。   In addition, since the entire web plate of the upper and lower divided beam members is joined by the joint member, the supporting force of each part is effective in average to prevent deformation such as sagging.

請求項２に係る発明によれば、継手部材の複数の突片が一方は分割ビーム材の一方の壁に連続し、他方は他方の壁に内接するように配置されるため、同じ分割ビーム材を反転させて継手部材を突き合わせるだけで、両ビーム材の面一をなす結合が行われて、これに伴い両分割ビーム材の突片が重合するため、ビス、リベット等の止め部材による両者の接合に便利である。   According to the invention of claim 2, since the plurality of projecting pieces of the joint member are arranged so that one is continuous with one wall of the split beam material and the other is inscribed in the other wall, the same split beam material is provided. By simply reversing the joint members, the two beam members are joined together so that the projections of the two split beam members overlap. Convenient for joining.

請求項３に係る発明によれば、継手部材を嵌合する際、嵌入側の他方の突片又はこれを挟む為の小突片に、一方の突片側へ寄せる斜面を設けると、嵌合に伴いこの斜面が他方の突片を一方の突片に寄せ付ける作用をして正確な嵌合を行わせるだけでなく、斜面が推力を発生して嵌入する他方の突片を一方の突片へ押し付けて接合の強化を図ることができる。   According to the invention which concerns on Claim 3, when fitting the joint member, if the slope which approaches one protrusion piece side is provided in the other protrusion piece by the side of insertion, or the small protrusion piece for pinching this, it will be in fitting. Accordingly, the slope not only acts to bring the other projecting piece into contact with the one projecting piece, but also makes an accurate fitting, and the other projecting piece into which the inclined surface generates a thrust is fitted into the one projecting piece. It can be pressed to strengthen the bonding.

請求項４に係る発明によれば、請求項１に記載されると同様に継手部材を設けた上下の分割ビーム材と、上側と下側の接合端に突片の配置が反対となるように継手部材を設けた中間分割ビーム材を、相互の継手部材へ嵌合した後、嵌合に伴い重合した各ビーム材の突片を止め部材で接合して一体に結合するから、中間分割ビーム材によって一層大型化された複合ビームが形成されるもので、この複合ビームの効果は請求項１の効果と同様であるので、これを援用し重複しての説明は省略する。   According to the invention of claim 4, as described in claim 1, the upper and lower divided beam materials provided with joint members and the arrangement of the protruding pieces on the upper and lower joint ends are opposite to each other. After the intermediate split beam material provided with the joint member is fitted to the mutual joint members, the projecting pieces of the respective beam materials superposed with the fitting are joined together by the stopper member, so that the intermediate split beam material is joined together. As a result, a larger-sized composite beam is formed, and the effect of this composite beam is the same as that of the first aspect.

以下に本発明に係る複合ビームの実施形態を図面に基づいて説明する。   Embodiments of a composite beam according to the present invention will be described below with reference to the drawings.

図１において符号Ａは請求項１に係る複合ビームを示す。この複合ビームＡは、２つに分割形成された上分割ビーム材１と、下分割ビーム材２の接合側の端板３に軸線方向へ平行に突出する複数の突片４と突片５を反転させて突き合わせると、互いに嵌り合う関係位置で配置した継手部材６、継手部材６をそれぞれ設け、これら継手部材６、継手部材６を互いに嵌合させて、これに伴い重合した上分割ビーム材１、下分割ビーム材２の突片４と突片５を止め部材７で接合すると、上分割ビーム材１と下分割ビーム材２が面一をなすように結合されて大型の複合ビームＡを構成するものである。   In FIG. 1, a symbol A indicates a composite beam according to claim 1. This composite beam A includes a plurality of projecting pieces 4 and 5 projecting in parallel in the axial direction on an end plate 3 on the joining side of the upper divided beam material 1 divided into two and the lower divided beam material 2. A joint member 6 and a joint member 6 arranged at positions where they are fitted to each other when they are reversed are provided, and the joint member 6 and the joint member 6 are fitted to each other, and the upper split beam material is polymerized accordingly. 1. When the projecting piece 4 and the projecting piece 5 of the lower divided beam material 2 are joined by the stopper member 7, the upper divided beam material 1 and the lower divided beam material 2 are joined so as to be flush with each other, and the large composite beam A is formed. It constitutes.

上記上分割ビーム材１は、アルミニウム又はその合金を押出成形することで、図２に示す通り、上部の水平部８とその中央部から垂下する二重のウエブ板９でＴ字形をなすように形成されて、接合側の端板３に軸線方向へ平行に突出する一対の突片４と突片５を、突片４は一方のウエブ板９に連続し、突片５は他方のウエブ板９に内接するように位置付けして、反転させると互いが嵌り合う継手部材６を構成させてあり、又、上記突片５に近付けて端板３には、該突片４とで嵌り込んでくる突片５の先端部を挟む小突片１０を設けてある。   As shown in FIG. 2, the upper split beam material 1 is formed by extrusion molding of aluminum or its alloy so as to form a T-shape with an upper horizontal portion 8 and a double web plate 9 depending from the central portion. A pair of projecting pieces 4 and 5 that are formed and project in parallel to the axial direction on the end plate 3 on the joining side, the projecting piece 4 continues to one web plate 9, and the projecting piece 5 is the other web plate. The joint member 6 is configured so as to be inscribed in 9 and fit with each other when it is reversed. The joint member 6 is close to the projecting piece 5 and is fitted into the end plate 3 with the projecting piece 4. A small projecting piece 10 is provided to sandwich the tip of the coming projecting piece 5.

上記の通り突片５は、その先端を突片４と小突片１０との間へ嵌入させるので、小突片１０に当る面の先端は、先狭まりの斜面１１として、嵌合の際、この斜面１１に案内されて、突片５の先端が小突片１０に突き当らず突片４の間に入り込むようにするとともに、斜面１１の発生する推力で突片５を突片４へ押し付けられるようにしたものであり、上記斜面１１は小突片１０側に形成しても同様に機能する。   As described above, the projecting piece 5 has its tip inserted between the projecting piece 4 and the small projecting piece 10, so that the tip of the surface that contacts the small projecting piece 10 has a tapered slope 11, Guided by the slope 11, the tip of the projecting piece 5 does not hit the small projecting piece 10 and enters between the projecting pieces 4, and the projecting piece 5 is pressed against the projecting piece 4 by the thrust generated by the slope 11. Even if the inclined surface 11 is formed on the small projecting piece 10 side, it functions similarly.

上記下分割ビーム材２は、図３に示す通り、上記上分割ビーム材１を反転させて、上の水平部８が下側に位置し、その中央部から二重のウエブ板９、ウエブ板９が垂立して逆Ｔ字形をなすようにしたものであり、継手部材６の突片４と突片５の位置が上分割ビーム材１とは反対になる。従って、上分割ビーム材１の継手部材６と互いに嵌り合わせることができるものであって、継手部材６の構造は、当然上分割ビーム材１と同一であるので、同一部分に同一の符号を付して説明は省略する。   As shown in FIG. 3, the lower split beam material 2 is obtained by inverting the upper split beam material 1 so that the upper horizontal portion 8 is positioned on the lower side, and a double web plate 9 and a web plate are formed from the central portion. 9 is vertically inverted to form an inverted T shape, and the positions of the projecting piece 4 and the projecting piece 5 of the joint member 6 are opposite to those of the upper split beam material 1. Accordingly, the joint member 6 of the upper split beam member 1 can be fitted to each other, and the structure of the joint member 6 is naturally the same as that of the upper split beam member 1, so that the same parts are denoted by the same reference numerals. The description is omitted.

上記上分割ビーム材１と下分割ビーム材２とで複合ビームＡを構成するには、上分割ビーム材１の継手部材６と、下分割ビーム材２の継手部材６とを、図４（ａ）に示す通り、上分割ビーム材１の突片４が下分割ビーム材２の突片５の右側面に接し、上分割ビーム材１の突片５が下分割ビーム材２の突片４の右側面に接するように合わせて、上分割ビーム材１を下分割ビーム材２へ向って移動させると、上分割ビーム材１及び下分割ビーム材２の突片５及び突片５の先端が相手側の突片４と小突片１０との間へ向って進み、それぞれの斜面１１が小突片１０に当ると、斜面１１に案内されて突片４と小突片１０との間へ入り込み、嵌合が深まるに伴い、斜面１１により発生する推力で突片５は突片４へ押し付けられるから、継手部材６、継手部材６は図４（ｂ）に示す通りガタがないように嵌合する。すると、両ビーム材１と２の２組の突片４と突片５が重合するから、重合した２組の突片４と突片５にそれぞれ通孔１２を、図面には示してないが適当な間隔であけて、各通孔１２に止め部材７として例えばタッピングビスを締め込んで突片４と突片５を接合すれば、上分割ビーム材１と下分割ビーム材２はウエブ板９、ウエブ板９が面一をなすように一体結合されて、図１及び図５に示す通りの大型の複合ビームＡを構成する。   In order to form the composite beam A with the upper split beam member 1 and the lower split beam member 2, the joint member 6 of the upper split beam member 1 and the joint member 6 of the lower split beam member 2 are formed as shown in FIG. ), The protruding piece 4 of the upper divided beam material 1 is in contact with the right side surface of the protruding piece 5 of the lower divided beam material 2, and the protruding piece 5 of the upper divided beam material 1 is in contact with the protruding piece 4 of the lower divided beam material 2. When the upper divided beam material 1 is moved toward the lower divided beam material 2 so as to be in contact with the right side surface, the protruding pieces 5 of the upper divided beam material 1 and the lower divided beam material 2 and the tips of the protruding pieces 5 are opposed to each other. When it goes toward the side between the protruding piece 4 and the small protruding piece 10 and each inclined surface 11 hits the small protruding piece 10, it is guided by the inclined surface 11 and enters between the protruding piece 4 and the small protruding piece 10. As the fitting deepens, the projecting piece 5 is pressed against the projecting piece 4 by the thrust generated by the inclined surface 11. Timber 6 is fitted so as not as backlash shown in Figure 4 (b). Then, since the two sets of protruding pieces 4 and protruding pieces 5 of both beam members 1 and 2 are superposed, the through holes 12 are not shown in the drawings, respectively. If the projecting piece 4 and the projecting piece 5 are joined to each through hole 12 by fastening, for example, a tapping screw as a stop member 7 to each through-hole 12, the upper divided beam material 1 and the lower divided beam material 2 are connected to the web plate 9. The web plate 9 is integrally coupled so as to be flush with each other to form a large composite beam A as shown in FIGS.

図６において符号Ａは請求項４に係る複合ビームを示す。この複合ビームＡは、２つに分割形成された上分割ビーム材１と、下分割ビーム材２との間に中間分割ビーム材１３を挟んで、各々の接合端に突片４と突片５で構成される２組の継手部材６、継手部材６を嵌合して、これに伴い重合した４組の突片４と突片５を止め部材７で接合することにで、上分割ビーム材１と中間分割ビーム材１３と下分割ビーム材２のビーム材が、各々のウエブ板９とウエブ板１４が面一となるように結合された複合ビームＡを構成するものである。   In FIG. 6, reference numeral A denotes a composite beam according to claim 4. This composite beam A has a projecting piece 4 and a projecting piece 5 at each joint end with an intermediate divided beam material 13 sandwiched between an upper divided beam material 1 divided into two and a lower divided beam material 2. The upper split beam material is formed by fitting two sets of joint members 6 and 6 and the four sets of projecting pieces 4 and 5 that are superposed together with the joint members 6 by the stopper members 7. The beam material 1, the intermediate divided beam material 13, and the lower divided beam material 2 constitute a composite beam A in which the web plate 9 and the web plate 14 are joined so as to be flush with each other.

この複合ビームＡの構成に用いる上分割ビーム材１と下分割ビーム材２は、請求項１に係る複合ビームＡを構成したものと同一のものを用いるので、同一部分に同一符号を付して説明は省略する。   Since the upper divided beam material 1 and the lower divided beam material 2 used for the configuration of the composite beam A are the same as those constituting the composite beam A according to claim 1, the same reference numerals are given to the same portions. Description is omitted.

中間分割ビーム材１３は、アルミニウム又はその合金を押出成形することで、図７、図８に示す通り、上分割ビーム材１及び下分割ビーム材２の２重ウエブ板９、ウエブ板９と等間隔の２重ウエブ板１４、ウエブ板１４と両端板１５、端板１５とでＩ形をなすように形成されて、両方の端板１５、端板１５に軸線方向へ平行に突出する一対の突片４と突片５を、上側のものは突片４が左側のウエブ板１４に連続して、突片５が右側のウエブ板１４に内接し、下側のものは突片４が右側のウエブ板１４に連続して、突片５が左側のウエブ板１４に内接するように位置付けした継手部材６、継手部材６を設けられ、又、上記突片４に近付けて端板１５には、該突片４とで嵌り込む突片５の先端部を挟む小突片１０を設けてある。   The intermediate divided beam member 13 is formed by extrusion molding of aluminum or an alloy thereof, as shown in FIGS. 7 and 8, and the double divided web plate 9 of the upper divided beam member 1 and the lower divided beam member 2, the web plate 9, and the like. A pair of spaced double web plates 14, a pair of web plates 14 and both end plates 15, and end plates 15 are formed in an I shape, and a pair of both end plates 15 and end plates 15 project in parallel in the axial direction. The projecting piece 4 and the projecting piece 5 are arranged on the upper side so that the projecting piece 4 is continuous with the left web plate 14, the projecting piece 5 is inscribed in the right web plate 14, and the lower one has the projecting piece 4 on the right side. The joint member 6 and the joint member 6 are provided so that the protruding piece 5 is inscribed in the left web plate 14 continuously to the web plate 14, and the end plate 15 is provided close to the protruding piece 4. A small protruding piece 10 is provided that sandwiches the tip end of the protruding piece 5 fitted with the protruding piece 4.

上記の通り突片５は、その先端を突片４と小突片１０との間へ嵌入させるので、小突片１０に当る面の先端は先狭まりの斜面１１とし、嵌合の際、この斜面１１に案内されて、突片５の先端が小突片１０に突き当らず突片４の間へ入り込むようにするとともに、斜面１１の発生する推力で突片５を突片４へ押し付けられるようにするものであり、上記斜面１１は小突片１０側に形成しても同様に機能する。   As described above, since the tip of the protrusion 5 is inserted between the protrusion 4 and the small protrusion 10, the tip of the surface that contacts the small protrusion 10 is a tapered slope 11. Guided by the slope 11, the tip of the projecting piece 5 enters the projecting piece 4 without hitting the small projecting piece 10, and the projecting piece 5 is pressed against the projecting piece 4 by the thrust generated by the slope 11. Even if the inclined surface 11 is formed on the small protruding piece 10 side, it functions similarly.

上記上分割ビーム材１と下分割ビーム材２と中間分割ビーム材１３で複合ビームＡを構成するには、先ず、中間分割ビーム材１３の継手部材６と、下分割ビーム材２の継手部材６を、図９（ａ）に示す通り、中間分割ビーム材１３の突片４が下分割ビーム材２の突片５の右側面へ接し、中間分割ビーム材１３の突片５が下分割ビーム材２の突片４の右側面へ接するように合わせて、中間分割ビーム材１３を下分割ビーム材２へ向って移動させると、中間分割ビーム材１３及び下分割ビーム材２の突片５及び突片５の先端が相手側の突片４と小突片１０との間へ向って進み、それぞれの斜面１１が小突片１０に当ると、斜面１1に案内されて突片４と小突片１０との間へ入り込み、嵌合が深まるに伴い、斜面１１により発生する推力で突片５は突片４に押し付けられるから、継手部材６、継手部材６は図９（ｂ）に示す通りガタがないように接合される。   In order to form the composite beam A with the upper divided beam material 1, the lower divided beam material 2, and the intermediate divided beam material 13, first, the joint member 6 of the intermediate divided beam material 13 and the joint member 6 of the lower divided beam material 2. 9 (a), the protruding piece 4 of the intermediate divided beam member 13 is in contact with the right side surface of the protruding piece 5 of the lower divided beam member 2, and the protruding piece 5 of the intermediate divided beam member 13 is the lower divided beam member. When the intermediate split beam member 13 is moved toward the lower split beam member 2 so as to be in contact with the right side surface of the second protrusion piece 4, the intermediate split beam member 13 and the lower split beam member 2 have the protruding pieces 5 and the protrusions. When the tip of the piece 5 advances between the opposite protruding piece 4 and the small protruding piece 10 and each inclined surface 11 hits the small protruding piece 10, the protruding piece 4 and the small protruding piece are guided by the inclined surface 11. 10 and the protrusion 5 is projected by the thrust generated by the inclined surface 11 as the fitting deepens. Since it is pressed against the piece 4, the joint member 6 and the joint member 6 are joined so that there is no backlash as shown in FIG. 9B.

このように下分割ビーム材２と中間分割ビーム材１３が継手部材６、継手部材６で接合されたら、中間分割ビーム材１３の継手部材６と、上分割ビーム材１の継手部材６を対応させて、上記同様の操作を繰り返せば、中間分割ビーム材１３の継手部材６と上分割ビーム材１の継手部材６もガタがないように接合されるから、接合に伴い重合した４組の突片４と突片５に図９（ｂ）に示す通り通孔１２を適当な間隔であけて、これら通孔１２に止め部材７として例えばタッピングビスを締め込めば、上分割ビーム材１と下分割ビーム材２が中間分割ビーム材１３を挟んで、各々のウエブ板９やウエブ板１４が面一となるように一体結合されて、図６に示す通りの構造で一層大型化された複合ビームＡを構成することができる。なお、中間分割ビーム材１３を増やす事により、さらに大型な複合ビームＡを構成することができる。   When the lower split beam member 2 and the intermediate split beam member 13 are joined by the joint member 6 and the joint member 6 in this way, the joint member 6 of the intermediate split beam member 13 and the joint member 6 of the upper split beam member 1 are made to correspond. If the same operation as described above is repeated, the joint member 6 of the intermediate split beam member 13 and the joint member 6 of the upper split beam member 1 are joined so that there is no backlash. 4 and the projecting piece 5 as shown in FIG. 9 (b), through holes 12 are formed at appropriate intervals, and, for example, a tapping screw is fastened as a stop member 7 to these through holes 12, the upper divided beam material 1 and the lower divided member are separated. The beam material 2 is integrally coupled so that the web plate 9 and the web plate 14 are flush with each other with the intermediate split beam material 13 interposed therebetween, and the composite beam A is further enlarged in a structure as shown in FIG. Can be configured. Note that a larger composite beam A can be formed by increasing the number of intermediate split beam members 13.

本発明は、分割ビーム材の継手接合を採用することで、施工容易で安価な大型ビームを提供するのに利用できる。   INDUSTRIAL APPLICABILITY The present invention can be used to provide a large beam that is easy to construct and inexpensive by adopting joint joining of split beam materials.
