Description

本発明は、建物の柱梁架構内に補強柱を設置する柱梁架構における補強柱の設置構造及び同構造を備えた建物に関するものである。   The present invention relates to a structure for installing a reinforcing column in a column beam frame in which a reinforcing column is installed in a column beam frame of a building, and a building having the same structure.

従来、建物における柱梁架構内の溝形鋼の梁・梁間に補強柱を設置する場合、溝形鋼又は角型鋼管の補強柱の端部に端部プレートを設け、この端部プレートと梁のフランジ部との間をボルト接合又は溶接接合により接合している。   Conventionally, when installing reinforcing columns between beams of channel steel in a column beam frame in a building, an end plate is provided at the end of the reinforcing column of channel steel or square steel pipe, and this end plate and beam Are joined by bolt joint or weld joint.

例えば特許文献１では、溝形鋼の補強柱の端部に端部プレートを設け、この端部プレートと溝形鋼の梁のフランジ部との間をボルト接合により接合した構成が開示されている。
特開２０００−１７０２６１号公報 For example, Patent Document 1 discloses a configuration in which an end plate is provided at an end portion of a reinforcing column made of channel steel, and the end plate and a flange portion of the beam of the channel steel are joined by bolt joining. .
JP 2000-170261 A

しかしながら、上記した従来の柱梁架構における補強柱の設置構造では、いずれにしても溝形鋼の梁の小さな強度しか担わないフランジ部に、補強柱端部の端部プレートが接合される構成なので、補強柱の曲げモーメントを溝形鋼の梁の大きな強度を担うウェブ部に効率的に伝達させることができず、柱梁架構全体の剛性を十分に高めることができなかった。   However, in the above-described conventional structure for installing the reinforcing column in the column beam structure, the end plate of the reinforcing column end is joined to the flange portion that bears only the small strength of the grooved steel beam in any case. The bending moment of the reinforcing column could not be efficiently transmitted to the web portion responsible for the great strength of the channel steel beam, and the rigidity of the entire column beam frame could not be sufficiently increased.

その対策として、補強柱の接合部における溝形鋼の梁の内部に、複数枚のスチフナーを梁のフランジ部とウェブ部を繋いで溶接接合することで、溝形鋼の梁の大きな強度を担うウェブ部に、補強柱の曲げモーメントを伝達させることもなされる。しかし、この場合、梁内部に多くの溶接を行うことになるので、施工が煩雑であり手間がかかっていた。   As a countermeasure, a large number of stiffeners are welded and joined to the inside of the grooved steel beam at the joint of the reinforcing column, connecting the flange part and the web part of the beam, thereby taking on the great strength of the grooved steel beam. The bending moment of the reinforcing column is also transmitted to the web portion. However, in this case, since many weldings are performed inside the beam, the construction is complicated and time-consuming.

そこで、本発明は、補強柱の曲げモーメントを溝形鋼の梁の大きな強度を担うウェブ部へ効率的に伝達して柱梁架構全体の剛性を十分に高めることができ、さらに、溶接を多用せずに施工性に優れた柱梁架構における補強柱の設置構造及び同構造を備えた建物を提供することを目的としている。   Therefore, the present invention can efficiently transmit the bending moment of the reinforcing column to the web part that bears the great strength of the channel steel beam, and can sufficiently increase the rigidity of the entire column beam frame. It aims at providing the building provided with the installation structure of the reinforcement pillar in the column beam frame excellent in workability, and the structure.

前記目的を達成するために、本発明の柱梁架構における補強柱の設置構造は、建物の柱梁架構内に補強柱を設置する柱梁架構における補強柱の設置構造であって、前記柱梁架構を構成する梁は、溝形鋼又はリップ付き溝形鋼であり、前記補強柱には、その端部に端部プレートが設けられ、さらに、その端部側面から当該補強柱の材軸方向に突出した接合プレートが設けられており、前記接合プレートが前記梁のウェブ部へ接合されて、前記柱梁架構内に前記補強柱が設置されていることを特徴とする。   To achieve the above object, the reinforcing column installation structure in the column beam frame of the present invention is a reinforcing column installation structure in a column beam frame in which a reinforcement column is installed in a column beam frame of a building, The beam constituting the frame is channel steel or channel steel with a lip, and the reinforcing column is provided with an end plate at an end thereof, and further from the side surface of the end portion in the material axis direction of the reinforcing column And a reinforcing plate is installed in the column beam frame by bonding the bonding plate to the web portion of the beam.

ここで、前記補強柱の前記接合プレートは、前記梁の前記ウェブ部へボルトとナットで接合してもよい。   Here, the joining plate of the reinforcing column may be joined to the web portion of the beam with a bolt and a nut.

具体的には、前記接合プレートには、その接合面側へ突出するようにボルトが一体に設けられ、前記梁の前記ウェブ部にはボルト孔が設けられ、前記ボルト孔へ前記ボルトが通され、当該ボルトにナットが螺着されて、前記接合プレートが前記梁の前記ウェブ部へ接合されていてもよい。   Specifically, the joint plate is integrally provided with a bolt so as to protrude to the joint surface side, the web portion of the beam is provided with a bolt hole, and the bolt is passed through the bolt hole. The nut may be screwed onto the bolt, and the joining plate may be joined to the web portion of the beam.

また、前記補強柱の前記接合プレート又は前記端部プレートに、前記補強柱の側面を挟み込む延長プレートが設けられており、当該延長プレートの先端部分には前記補強柱の奥行き方向に折り曲げられた曲げモーメント伝達部が形成されていてもよい。   Further, an extension plate that sandwiches the side surface of the reinforcing column is provided on the joining plate or the end plate of the reinforcing column, and a bent portion that is bent in the depth direction of the reinforcing column is provided at a distal end portion of the extension plate. A moment transmission portion may be formed.

また、前記補強柱が溝形鋼又はリップ付き溝形鋼である場合においては、前記延長プレートの前記曲げモーメント伝達部が挟み込んだ部位の前記補強柱の凹部にスチフナーが設けられていてもよい。   Further, when the reinforcing column is channel steel or channel steel with a lip, a stiffener may be provided in the concave portion of the reinforcing column at a portion sandwiched by the bending moment transmitting portion of the extension plate.

さらに、本発明の建物は、上記した柱梁架構における補強柱の設置構造を備えた建物において、前記柱梁架構は、その底部が単純支持されているとともに、下側の梁の前記補強柱の下部の部位又は下側の梁の略中央の部位が支持されていることを特徴とする。   Furthermore, the building of the present invention is a building having the above-described structure for installing the reinforcing column in the column beam frame. The column beam frame is simply supported at the bottom, and the reinforcing column of the lower beam The lower part or the substantially central part of the lower beam is supported.

このように構成された本発明の柱梁架構における補強柱の設置構造は、補強柱の端部側面から突出した接合プレートが溝形鋼又はリップ付き溝形鋼の梁のウェブ部と接合された構成なので、補強柱の曲げモーメントを接合プレートから溝形鋼又はリップ付き溝形鋼の梁の大きな強度を担うウェブ部へ効率的に伝達して柱梁架構全体の剛性を高めることができ、製造が容易なので、経済性にも優れている。   The reinforcing column installation structure in the column beam frame of the present invention configured as described above is such that the joining plate protruding from the side surface of the end of the reinforcing column is joined to the web portion of the beam of the grooved steel or the grooved steel with the lip. Because of the structure, the bending moment of the reinforcing column can be efficiently transmitted from the joining plate to the web part responsible for the large strength of the beam of channel steel or channel steel with lip, and the rigidity of the column beam frame as a whole can be increased. Is easy and economical.

また、補強柱の接合プレートを、梁のウェブ部へボルトとナットで接合する場合は、従来技術に比して、溶接を多用しないこととなるので、施工性にも優れる。   In addition, when the joining plate of the reinforcing column is joined to the web portion of the beam with bolts and nuts, welding is not frequently used as compared with the prior art, so that the workability is excellent.

また、接合プレートの接合面側にボルトを一体に設け、梁のウェブ部にボルト孔を設け、ナットで接合プレートを梁のウェブ部へ接合する場合は、施工がより簡易に行える。さらに、建物ユニットの柱梁架構においては、隣り合う建物ユニットの梁・梁間の納まりがよくなる。   Further, when the bolt is integrally provided on the joining surface side of the joining plate, the bolt hole is provided in the web portion of the beam, and the joining plate is joined to the web portion of the beam with a nut, the construction can be performed more easily. Furthermore, in the column beam structure of a building unit, the fit between the beams of adjacent building units is improved.

また、補強柱の接合プレート又は端部プレートに、補強柱の側面を挟み込む延長プレートを設け、この延長プレートの先端部分に補強柱の奥行き方向に折り曲げられた曲げモーメント伝達部を形成した場合は、補強柱の曲げモーメントを溝形鋼又はリップ付き溝形鋼の梁の大きな強度を担うウェブ部へさらに効率的に伝達して柱梁架構全体の剛性をより高めることができる。   In addition, when the extension plate that sandwiches the side surface of the reinforcing column is provided on the joining plate or the end plate of the reinforcing column, and the bending moment transmitting portion that is bent in the depth direction of the reinforcing column is formed at the tip of the extension plate, The bending moment of the reinforcing column can be more efficiently transmitted to the web portion responsible for the large strength of the beam of the channel steel or the channel steel with the lip, and the rigidity of the entire column beam frame can be further increased.

さらに、補強柱が溝形鋼又はリップ付き溝形鋼である場合において、延長プレートの曲げモーメント伝達部が挟み込んだ部位の補強柱の凹部にスチフナーを設ける構成とすると、溝形鋼又はリップ付き溝形鋼の補強柱においても、その曲げモーメントを溝形鋼又はリップ付き溝形鋼の梁の大きな強度を担うウェブ部へ効率的に伝達して柱梁架構全体の剛性を高めることができる。   Further, when the reinforcing column is a grooved steel or a grooved steel with a lip, if the stiffener is provided in the concave portion of the reinforcing column at the portion where the bending moment transmitting portion of the extension plate is sandwiched, the grooved steel or the groove with the lip Even in the reinforcing column of a section steel, the bending moment can be efficiently transmitted to the web portion that bears the high strength of the beam of the channel steel or the channel steel with a lip, thereby enhancing the rigidity of the entire column beam frame.

また、このように構成された本発明の建物は、柱梁架構の底部が単純支持するとともに、荷重が大きくかかる下側の梁の補強柱の下部の部位又は最も応力が大きい下側の梁の略中央の部位を支持することにより、建物の剛性をより大きくすることができる。   In addition, the building of the present invention constructed as described above is simply supported by the bottom of the column beam frame, and the lower part of the reinforcement column of the lower beam where the load is large or the lower beam having the highest stress is applied. By supporting the substantially central portion, the rigidity of the building can be further increased.

実施例３の柱梁架構における補強柱の設置構造も、図１に示したように、建物としての建物ユニット１の柱梁架構２内に補強柱３を設置する構造である。図１０〜図１３に示したように、柱梁架構２を構成する梁としての天井梁４及び床梁５は、溝形鋼である。また、角型鋼の補強柱３の上下端部に端部プレート６がそれぞれ設けられ、さらに、上下の端部プレート６の端部からこの補強柱３の材軸方向に突出した接合プレート７がそれぞれ設けられている。そして、補強柱３の上端部において、接合プレート７が天井梁４のウェブ部４ｂへボルト８，・・・・・とナット９，・・・・・とで接合されている。また、補強柱３の下端部においても、接合プレート７が床梁５のウェブ部５ｂへボルト８，・・・・・とナット９，・・・・・とで接合されている。これにより、柱梁架構２内に補強柱３が設置された構成とされている。   As shown in FIG. 1, the installation structure of the reinforcing columns in the column beam frame of the third embodiment is also a structure in which the reinforcement columns 3 are installed in the column beam frame 2 of the building unit 1 as a building. As shown in FIGS. 10 to 13, the ceiling beam 4 and the floor beam 5 as beams constituting the column beam frame 2 are channel steel. Further, end plates 6 are respectively provided at the upper and lower ends of the reinforcing pillars 3 made of square steel, and the joining plates 7 projecting from the ends of the upper and lower end plates 6 in the material axis direction of the reinforcing pillars 3 are respectively provided. Is provided. At the upper end portion of the reinforcing column 3, the joining plate 7 is joined to the web portion 4 b of the ceiling beam 4 with bolts 8,. Also at the lower end portion of the reinforcing column 3, the joining plate 7 is joined to the web portion 5 b of the floor beam 5 with bolts 8,... And nuts 9,. Thereby, it is set as the structure by which the reinforcement pillar 3 was installed in the column beam frame 2. FIG.

実施例３の柱梁架構における補強柱の設置構造は、先端部に曲げモーメント伝達部７ｂを形成した延長プレート７ａ，７ａを設けていないことが、実施例１，２と主に異なる。なお、他の構成は、実施例１，２と略同様であるので、対応する構成に同一符号を付して説明を省略する。   The installation structure of the reinforcing column in the column beam frame of the third embodiment is mainly different from the first and second embodiments in that the extension plates 7a and 7a having the bending moment transmitting portion 7b formed at the tip are not provided. Since other configurations are substantially the same as those of the first and second embodiments, the corresponding components are denoted by the same reference numerals and description thereof is omitted.

ここで、上下の矩形状の接合プレート７，７は、先端部に曲げモーメント伝達部７ｂを形成した延長プレート７ａ，７ａを設けていないことを補うために、実施例１，２よりも厚い端部プレート６の端部に溶接接合により接合されている。   Here, the upper and lower rectangular joining plates 7 and 7 are thicker than the first and second embodiments in order to compensate for the fact that the extension plates 7a and 7a having the bending moment transmitting portion 7b formed at the tip are not provided. It joins to the edge part of the part plate 6 by welding joining.

このように構成された実施例３の柱梁架構における補強柱の設置構造は、上記した実施例１の（１）〜（３）の効果に加え、先端部に曲げモーメント伝達部７ｂを形成した延長プレート７ａ，７ａを設けていない構成としているので、より簡易な構成で、補強柱３の曲げモーメントを溝形鋼の天井梁４及び床梁５の大きな強度を担うウェブ部４ｂ，５ｂへ効率的に伝達して柱梁架構２全体の剛性を高めることができる。   In addition to the effects (1) to (3) of the first embodiment, the installation structure of the reinforcing columns in the column beam frame of the third embodiment configured as described above has a bending moment transmitting portion 7b formed at the tip. Since the extension plates 7a and 7a are not provided, the bending moment of the reinforcing column 3 is efficiently transferred to the web portions 4b and 5b that bear the high strength of the grooved steel ceiling beam 4 and floor beam 5 with a simpler configuration. Can be transmitted to increase the rigidity of the entire column beam frame 2.

以下、本発明の建物を実現する最良の形態を、図面に示す実施例４，５に基づいて説明する。   Hereinafter, the best mode for realizing the building of the present invention will be described based on Examples 4 and 5 shown in the drawings.

先ず、実施例４の建物について説明する。   First, the building of Example 4 will be described.
