Description

本発明は、柱と大梁とで骨組体を構成する、隣り合う建物ユニットの柱を省略した大梁間に使用される大梁間接続金具、大梁間接続構造及びユニット建物に関するものである。 The present invention relates to an inter-beam connection fitting, an inter-beam connection structure, and a unit building, which are used between columns omitting columns of adjacent building units, which form a framework of columns and girders.

従来、隣り合う建物ユニットの大梁間に使用される大梁間接続構造が知られている（例えば、特許文献１参照）。 Conventionally, a girder-to-beam connection structure used between girders of adjacent building units is known (see, for example, Patent Document 1).

特許文献１には、柱省略建物ユニットのジョイントピースのウエブと、柱省略建物ユニットの天井梁のウエブと、補強梁と、を高力ボルトにより摩擦接合する構成が開示されている。また、特許文献１には、水平ブレースを取り付けるためのブレース固定板を有する水平ブレース取付部材を、単柱にボルトで取り付ける構成が開示されている。 Patent Document 1 discloses a configuration in which a web of a joint piece of a building unit without columns, a web of a ceiling beam of a building unit without columns, and a reinforcing beam are frictionally joined by high-strength bolts. Further, Patent Document 1 discloses a configuration in which a horizontal brace attachment member having a brace fixing plate for attaching a horizontal brace is attached to a single column with bolts.

特開平９−３１７０１８公報Japanese Unexamined Patent Publication No. 9-317018

しかしながら、特許文献１に記載の発明では、単柱の径によって、異なるサイズのブレース固定板やボルトを必要とし、部品の共通化ができない、という問題がある。 However, the invention described in Patent Document 1 has a problem that different sizes of brace fixing plates and bolts are required depending on the diameter of a single column, and parts cannot be shared.

そこで、本発明は、柱の径に依らず、部品を共通化することができる大梁間接続金具、大梁間接続構造及びユニット建物を提供することを目的としている。 Therefore, an object of the present invention is to provide a girder-to-beam connection fitting, a girder-to-beam connection structure, and a unit building capable of sharing parts regardless of the diameter of columns.

前記目的を達成するために、本発明の大梁間接続金具は、柱と大梁とで骨組体を構成する、隣り合う建物ユニットの前記柱を省略した大梁間に使用される大梁間接続金具であって、隣り合う前記建物ユニットのそれぞれに設けられる第１部材と、それぞれの前記第１部材に取り付けられる、水平ブレースを支持する第２部材と、を備え、前記第１部材は、第１片と、前記第１片に直交する第２片と、で断面Ｌ字状に形成され、前記第２部材は、前記水平ブレースが取り付けられる本体部と、前記本体部を支持する基部とを備え、前記基部は、第１基部と、前記第１基部に直交する第２基部と、で断面Ｌ字状に形成され、前記第１部材と前記第２部材には、前記第１部材と前記第２部材を一体化する孔が形成されていることを特徴とする。 In order to achieve the above object, the inter-beam connection fitting of the present invention is an inter-beam connection fitting used between girders of adjacent building units in which the columns are omitted, which constitutes a frame with columns and girders. A first member provided in each of the adjacent building units and a second member attached to each of the first members to support the horizontal brace are provided, and the first member is a first piece. The second piece orthogonal to the first piece is formed in an L-shaped cross section, and the second member includes a main body portion to which the horizontal brace is attached and a base portion that supports the main body portion. The base portion is formed in an L-shaped cross section by a first base portion and a second base portion orthogonal to the first base portion, and the first member and the second member include the first member and the second member. It is characterized in that a hole for integrating the above is formed.

ここで、本発明の大梁間接続金具では、前記本体部は、前記基部の入り隅部から水平方向に延在して形成されてもよい。 Here, in the girder-to-beam connection fitting of the present invention, the main body portion may be formed so as to extend in the horizontal direction from the entrance corner portion of the base portion.

また、本発明の大梁間接続金具では、前記第１部材は、上下方向の端部に設けられる端部プレートを備えてもよい。 Further, in the girder-to-beam connection fitting of the present invention, the first member may include an end plate provided at an end portion in the vertical direction.

また、本発明の大梁間接続金具では、前記孔は、前記第２部材の前記基部の出隅部を前記第１部材の入り隅部に当接させた状態で、同じ位置に形成され、前記孔にボルトが挿通されて、前記第２部材が前記第１部材に取り付けられていてもよい。 Further, in the inter-beam connection fitting of the present invention, the hole is formed at the same position in a state where the protruding corner portion of the base portion of the second member is in contact with the entrance corner portion of the first member. The second member may be attached to the first member by inserting a bolt into the hole.

また、本発明の大梁間接続金具では、前記第１片の厚さは、前記第２片の厚さより厚くてもよい。 Further, in the girder-to-beam connection fitting of the present invention, the thickness of the first piece may be thicker than the thickness of the second piece.

また、本発明の上記大梁間接続金具を使用した大梁間接続構造では、隣り合う２つの前記建物ユニットの前記第１部材は、出隅部を向かい合わせにして配置され、前記孔に１本のボルトが挿入されて、共締めされていてもよい。 Further, in the beam-to-beam connection structure using the beam-to-beam connection fitting of the present invention, the first member of the two adjacent building units is arranged so that the protruding corners face each other, and one hole is provided. Bolts may be inserted and tightened together.

また、本発明の大梁間接続構造では、隣り合う４つの前記建物ユニットの前記第１部材は、前記出隅部を向かい合わせにして配置され、前記大梁間を補強する補強板を挟んで両側に２つの前記第１部材が配置されてもよい。 Further, in the inter-beam connection structure of the present invention, the first members of the four adjacent building units are arranged so that the protruding corners face each other, and the reinforcing plates for reinforcing the inter-beams are interposed therebetween. The two first members may be arranged.

さらに、本発明のユニット建物では、上記大梁間接続構造を有するユニット建物としてもよい。 Further, the unit building of the present invention may be a unit building having the above-mentioned connection structure between girders.

このように構成された本発明の大梁間接続金具では、隣り合う建物ユニットのそれぞれに設けられる第１部材と、それぞれの第１部材に取り付けられる、水平ブレースを支持する第２部材と、を備え、第１部材は、第１片と、第１片に直交する第２片と、で断面Ｌ字状に形成され、第２部材は、水平ブレースが取り付けられる本体部と、本体部を支持する基部とを備え、基部は、第１基部と、第１基部に直交する第２基部と、で断面Ｌ字状に形成され、第１部材と第２部材には、第１部材と第２部材を一体化する孔が形成されている。そのため、第１部材の径に依らず、第２部材の出隅部を、第１部材の入り隅部に当接させて、第２部材を第１部材に取り付けることができる。その結果、第１部材の径の影響を受けることなく、第２部材を共通化して、第２部材を第１部材に取り付けることができる。 The girder-to-beam connection fitting of the present invention configured in this way includes a first member provided in each of adjacent building units and a second member attached to each of the first members to support the horizontal brace. , The first member is formed by a first piece and a second piece orthogonal to the first piece in an L-shaped cross section, and the second member supports a main body portion to which a horizontal brace is attached and a main body portion. A base portion is provided, and the base portion is formed in an L-shaped cross section by a first base portion and a second base portion orthogonal to the first base portion, and the first member and the second member are the first member and the second member. A hole is formed to integrate the above. Therefore, regardless of the diameter of the first member, the outer corner portion of the second member can be brought into contact with the inner corner portion of the first member, and the second member can be attached to the first member. As a result, the second member can be shared and the second member can be attached to the first member without being affected by the diameter of the first member.

また、本体部は、基部の入り隅部から水平方向に延在して形成されていることで、第１部材の径に依らず、第２部材の出隅部を、第１部材の入り隅部に当接させて、第２部材を第１部材に取り付けることができる。その結果、第１部材の径の影響を受けることなく、第２部材を共通化して、第２部材を第１部材に取り付けることができる。 Further, since the main body portion is formed so as to extend in the horizontal direction from the inside corner portion of the base portion, the outside corner portion of the second member can be the inside corner portion of the first member regardless of the diameter of the first member. The second member can be attached to the first member by abutting the portion. As a result, the second member can be shared and the second member can be attached to the first member without being affected by the diameter of the first member.

また、第１部材は、上下方向の端部に設けられる端部プレートを備えることで、第１部材の剛性を向上させることができる。そのため、大梁間接続金具の剛性を向上させることができる。 Further, the rigidity of the first member can be improved by providing the end plate provided at the end portion in the vertical direction of the first member. Therefore, the rigidity of the girder-to-beam connection fitting can be improved.

また、孔は、第２部材の基部の出隅部を第１部材の入り隅部に当接させた状態で、同じ位置に形成され、孔にボルトが挿通されて、第２部材が第１部材に取り付けられていることで、第２部材が第１部材に位置決めされた状態で、ボルトを、第１部材と第２部材とにそれぞれ形成された孔に挿入することができる。そのため、第２部材を第１部材に簡単に取り付けることができる。 Further, the holes are formed at the same positions in a state where the protruding corners of the base of the second member are in contact with the entrance corners of the first member, and bolts are inserted into the holes so that the second member becomes the first. By being attached to the member, the bolt can be inserted into the holes formed in the first member and the second member, respectively, while the second member is positioned in the first member. Therefore, the second member can be easily attached to the first member.

また、第１片の厚さは、第２片の厚さより厚いことで、第１片の強度を、第２片の強度より強くすることができ、設計の自由度を向上させることができる。 Further, since the thickness of the first piece is thicker than the thickness of the second piece, the strength of the first piece can be made stronger than the strength of the second piece, and the degree of freedom in design can be improved.

また、上記大梁間接続金具を使用した大梁間接続構造において、隣り合う２つの建物ユニットの第１部材は、出隅部を向かい合わせにして配置され、孔に１本のボルトが挿入されて、共締めされていることで、第１部材の径が大きい場合でも、第１部材の径が小さい場合でも、第１部材の厚さを同じ厚さにすることで、同じ長さのボルトによって、隣り合う建物ユニットの第１部材を連結することができる。そのため、第１部材の径の影響を受けることなく、ボルトを共通化して、隣り合う建物ユニットの第１部材を連結することができる。 Further, in the girder-to-girder connection structure using the girder-to-beam connection fitting, the first members of two adjacent building units are arranged so that the protruding corners face each other, and one bolt is inserted into the hole. By being co-tightened, even if the diameter of the first member is large or the diameter of the first member is small, by making the thickness of the first member the same, the bolts of the same length can be used. The first members of adjacent building units can be connected. Therefore, the bolts can be shared and the first members of adjacent building units can be connected without being affected by the diameter of the first member.

また、隣り合う４つの建物ユニットの第１部材は、出隅部を向かい合わせにして配置され、大梁間を補強する補強板を挟んで両側に２つの第１部材が配置されていることで、隣り合う２つの建物ユニットの第１部材を１本のボルトで連結すると共に、補強板で補強することができる。そのため、大梁間接続構造の剛性を向上させることができる。 Further, the first members of the four adjacent building units are arranged so that the protruding corners face each other, and the two first members are arranged on both sides of the reinforcing plate that reinforces the space between the girders. The first members of two adjacent building units can be connected by one bolt and reinforced by a reinforcing plate. Therefore, the rigidity of the girder-to-beam connection structure can be improved.

また、上記の大梁間接続構造を有するユニット建物とすることで、柱や第１部材の径に依らず、部品を共通化した大梁間接続構造を有するユニット建物を構築することができる。 Further, by adopting the unit building having the above-mentioned inter-beam connection structure, it is possible to construct the unit building having the common girder connection structure regardless of the diameter of the column or the first member.

［大梁間接続金具、大梁間接続構造及びユニット建物の作用］
以下、実施例１の大梁間接続金具３０、大梁間接続構造及びユニット建物１の作用を説明する。実施例１の大梁間接続金具３０は、柱１１と大梁（天井大梁１３）とで骨組体を構成する、隣り合う建物ユニット１０の柱１１を省略した大梁（天井大梁１３）間に使用される。大梁間接続金具３０は、隣り合う建物ユニット１０のそれぞれに設けられる第１部材４０と、それぞれの第１部材４０に取り付けられる、水平ブレース１８を支持する第２部材５０と、を備え、第１部材４０は、第１片４１と、第１片４１に直交する第２片４２と、で断面Ｌ字状に形成され、第２部材５０は、水平ブレース１８が取り付けられる本体部５３と、本体部５３を支持する基部５０Ａとを備え、基部５０Ａは、第１基部５１と、第１基部５１に直交する第２基部５２と、で断面Ｌ字状に形成され、第１部材４０と第２部材５０には、第１部材４０と第２部材５０を一体化する孔（第１片貫通孔４１ａ，第１基部貫通孔５１ａ）が形成されている（図７）。 [Operation of girder connection fittings, girder connection structure and unit building]
Hereinafter, the operations of the girder-to-beam connection fitting 30, the girder-to-beam connection structure, and the unit building 1 of the first embodiment will be described. The inter-girder connection fitting 30 of the first embodiment is used between the girders (ceiling girders 13) in which the pillars 11 of the adjacent building units 10 are omitted, which constitutes a framework of the pillars 11 and the girders (ceiling girders 13). .. The girder-to-beam connection fitting 30 includes a first member 40 provided in each of the adjacent building units 10 and a second member 50 attached to each of the first members 40 to support the horizontal brace 18. The member 40 is formed by a first piece 41 and a second piece 42 orthogonal to the first piece 41 in an L-shaped cross section, and the second member 50 is a main body 53 to which a horizontal brace 18 is attached and a main body. A base portion 50A for supporting the portion 53 is provided, and the base portion 50A is formed by a first base portion 51 and a second base portion 52 orthogonal to the first base portion 51 in an L-shaped cross section, and the first member 40 and the second member 40 and the second base portion 50A. The member 50 is formed with holes (first piece through hole 41a, first base through hole 51a) for integrating the first member 40 and the second member 50 (FIG. 7).

これにより、第２部材５０の出隅部５６を、第１部材４０の入り隅部４５に当接させて、第２部材５０を第１部材４０に取り付けることができる。そのため、図７に示すように、柱１１の径が大きく第１部材４０の径が大きい場合でも、図４に示すように、柱１１の径が小さく第１部材４０の径が小さい場合でも、同じ第２部材５０を第１部材４０に当接させることができる。その結果、第１部材４０の径の影響を受けることなく、第２部材５０を共通化して、第２部材５０を第１部材４０に取り付けることができる。 As a result, the protruding corner portion 56 of the second member 50 can be brought into contact with the inside corner portion 45 of the first member 40, and the second member 50 can be attached to the first member 40. Therefore, as shown in FIG. 7, even when the diameter of the pillar 11 is large and the diameter of the first member 40 is large, or when the diameter of the pillar 11 is small and the diameter of the first member 40 is small as shown in FIG. The same second member 50 can be brought into contact with the first member 40. As a result, the second member 50 can be shared and the second member 50 can be attached to the first member 40 without being affected by the diameter of the first member 40.

実施例１の大梁間接続金具３０において、本体部５３は、基部５０Ａの入り隅部５５から水平方向に延在して形成されている（図６）。 In the girder-to-beam connection fitting 30 of the first embodiment, the main body portion 53 is formed so as to extend in the horizontal direction from the entrance corner portion 55 of the base portion 50A (FIG. 6).

これにより、第２部材５０の基部５０Ａの出隅部５６側を第１部材４０の入り隅部４５に当接させた状態にして、第２部材５０を第１部材４０に取り付けることができる。そのため、図７に示すように、柱１１の径が大きく第１部材４０の径が大きい場合でも、図４に示すように、柱１１の径が小さく第１部材４０の径が小さい場合でも、同じ第２部材５０を第１部材４０に当接させることができる。その結果、第１部材４０の径の影響を受けることなく、第２部材５０を共通化して、第２部材５０を第１部材４０に取り付けることができる。 As a result, the second member 50 can be attached to the first member 40 with the protruding corner 56 side of the base 50A of the second member 50 in contact with the inner corner 45 of the first member 40. Therefore, as shown in FIG. 7, even when the diameter of the pillar 11 is large and the diameter of the first member 40 is large, or when the diameter of the pillar 11 is small and the diameter of the first member 40 is small as shown in FIG. The same second member 50 can be brought into contact with the first member 40. As a result, the second member 50 can be shared and the second member 50 can be attached to the first member 40 without being affected by the diameter of the first member 40.

また、第２部材５０の出隅部５６側に本体部５３を設けるより、第２部材５０の入り隅部５５側に本体部５３を設ける方が、水平ブレース１８からの力を効率よく分散させることができる。そのため、大梁間接続金具３０の剛性を向上させることができる。 Further, it is more efficient to disperse the force from the horizontal brace 18 by providing the main body 53 on the entrance 55 side of the second member 50 than by providing the main body 53 on the protruding corner 56 side of the second member 50. be able to. Therefore, the rigidity of the girder-to-beam connection fitting 30 can be improved.

実施例１の大梁間接続金具３０において、第１部材４０は、上下方向の端部に設けられる端部プレート４３，４４を備える（図５）。 In the girder-to-beam connection fitting 30 of the first embodiment, the first member 40 includes end plates 43 and 44 provided at the ends in the vertical direction (FIG. 5).

これにより、第１部材４０の剛性を向上させることができる。そのため、大梁間接続金具３０の剛性を向上させることができる。また、簡易な構成で、第１部材４０に対して、第２部材５０の上下方向の位置決めをすることができる。 Thereby, the rigidity of the first member 40 can be improved. Therefore, the rigidity of the girder-to-beam connection fitting 30 can be improved. Further, with a simple configuration, the second member 50 can be positioned in the vertical direction with respect to the first member 40.

実施例１の大梁間接続金具３０において、孔（第１片貫通孔４１ａ，第１基部貫通孔５１ａ）は、第２部材５０の基部５０Ａの出隅部５６を第１部材４０の入り隅部４５に当接させた状態で、同じ位置に形成され、孔（第１片貫通孔４１ａ，第１基部貫通孔５１ａ）にボルト６１が挿通されて、第２部材５０が第１部材４０に取り付けられている（図４）。 In the girder-to-beam connection fitting 30 of the first embodiment, the holes (first piece through hole 41a, first base through hole 51a) are such that the protruding corner 56 of the base 50A of the second member 50 is the entrance corner of the first member 40. Formed at the same position in contact with 45, the bolt 61 is inserted into the holes (first piece through hole 41a, first base through hole 51a), and the second member 50 is attached to the first member 40. (Fig. 4).

これにより、第２部材５０が第１部材４０に位置決めされた状態で、ボルト６１を、第１部材４０と第２部材５０とにそれぞれ形成された孔（第１片貫通孔４１ａ，第１基部貫通孔５１ａ）に挿入することができる。そのため、第２部材５０を第１部材４０に簡単に取り付けることができる。 As a result, in a state where the second member 50 is positioned on the first member 40, the bolt 61 is inserted into the holes (first piece through hole 41a, first base portion) formed in the first member 40 and the second member 50, respectively. It can be inserted into the through hole 51a). Therefore, the second member 50 can be easily attached to the first member 40.

実施例１の大梁間接続金具３０において、第１片４１の厚さは、第２片４２の厚さより厚い（図５）。 In the girder-to-beam connection fitting 30 of the first embodiment, the thickness of the first piece 41 is thicker than the thickness of the second piece 42 (FIG. 5).

これにより、第１片４１の強度を、第２片４２の強度より強くすることができる。第１片４１を介して取り付けられる大梁（天井大梁１３）間の取付構造と、第２片４２を介して取り付けられる大梁（天井大梁１３）間の取付構造を異ならせても、期待する大梁（天井大梁１３）間の耐力を得られるようにすることができる。そのため、設計の自由度を向上させることができる。 Thereby, the strength of the first piece 41 can be made stronger than the strength of the second piece 42. Even if the mounting structure between the girders (ceiling girders 13) attached via the first piece 41 and the mounting structure between the girders (ceiling girders 13) attached via the second piece 42 are different, the expected girders (ceiling girders 13) It is possible to obtain the yield strength between the ceiling girders 13). Therefore, the degree of freedom in design can be improved.

実施例１の大梁間接続構造において、隣り合う２つの建物ユニット１０の第１部材４０は、出隅部４６を向かい合わせにして配置され、孔（第１片貫通孔４１ａ，第１基部貫通孔５１ａ）に１本のボルト６１が挿入されて、共締めされている（図４）。 In the girder-to-beam connection structure of the first embodiment, the first member 40 of the two adjacent building units 10 is arranged so that the protruding corners 46 face each other, and the holes (first piece through hole 41a, first base through hole) One bolt 61 is inserted into 51a) and fastened together (FIG. 4).

これにより、図７に示すように、柱１１の径が大きく第１部材４０の径が大きい場合でも、図４に示すように、柱１１の径が小さく第１部材４０の径が小さい場合でも、第１部材４０の厚さを同じ厚さにすることで、同じ長さのボルト６１によって、隣り合う建物ユニット１０の第１部材４０を連結することができる。そのため、第１部材４０の径の影響を受けることなく、ボルト６１を共通化して、隣り合う建物ユニット１０の第１部材４０を連結することができる。 As a result, even when the diameter of the pillar 11 is large and the diameter of the first member 40 is large as shown in FIG. 7, even when the diameter of the pillar 11 is small and the diameter of the first member 40 is small as shown in FIG. By making the thickness of the first member 40 the same, the first members 40 of the adjacent building units 10 can be connected by the bolts 61 having the same length. Therefore, the bolts 61 can be shared and the first members 40 of the adjacent building units 10 can be connected without being affected by the diameter of the first member 40.

また、１本のボルト６１で、第２部材５０を第１部材４０に取り付けると共に、隣り合う第１部材４０同士を固定することができる。そのため、部品数を少なくした大梁間接続構造とすることができる。 Further, the second member 50 can be attached to the first member 40 and the adjacent first members 40 can be fixed to each other with one bolt 61. Therefore, it is possible to have a girder-to-beam connection structure with a reduced number of parts.

実施例１の大梁間接続構造において、隣り合う４つの建物ユニット１０の第１部材４０は、出隅部４６を向かい合わせにして配置され、大梁（天井大梁１３）間を補強する補強板７０を挟んで両側に２つの第１部材４０が配置されている（図４）。 In the girder-to-girder connection structure of the first embodiment, the first members 40 of the four adjacent building units 10 are arranged with the protruding corners 46 facing each other, and a reinforcing plate 70 for reinforcing the girders (ceiling girders 13) is provided. Two first members 40 are arranged on both sides thereof (FIG. 4).

これにより、隣り合う２つの建物ユニット１０の第１部材４０を１本のボルト６１で連結すると共に、補強板７０で補強することができる。そのため、大梁間接続構造の剛性を向上させることができる。 As a result, the first member 40 of the two adjacent building units 10 can be connected by one bolt 61 and reinforced by the reinforcing plate 70. Therefore, the rigidity of the girder-to-beam connection structure can be improved.
