Description

本発明は、柱の機能を有する壁柱を備えた鉄骨鉄筋コンクリート造の壁柱建物構造に関する。   The present invention relates to a steel-framed reinforced concrete wall-column building structure having wall columns having column functions.

建物の構造の一つとして、建物の外周部に設けられた鉄骨鉄筋コンクリート(以後、SRCと呼ぶ)造の壁柱と、建物の内周部に設けられ、端部が壁柱に接合された鉄骨梁と、を備えるものがある。このように、強固な壁柱を建物の外周部に設けることで、建物内に配置する柱を減らし、建物内の居室空間を広く確保することが可能となっている。   As one of the structures of the building, a steel frame reinforced concrete (hereinafter, referred to as SRC) wall column provided on the outer periphery of the building and a steel frame provided on the inner periphery of the building and having an end joined to the wall column And a beam. As described above, by providing the strong wall pillars on the outer periphery of the building, the number of pillars arranged in the building can be reduced, and the room space in the building can be widely secured.

例えば、特許文献1には、建物の外壁面の位置に配置した外周柱と、隣接配置した外周柱の間に架設した外周梁と、建物内を横断して相対向する外周柱の間に架設した内部梁とを備える構成が開示されている。この構成において、外周柱は、芯鉄骨の周囲に鉄筋コンクリートからなる壁状の被覆コンクリートを一体に形成してなる鉄骨鉄筋コンクリート造の壁柱としている。
また、特許文献2には、鉄骨柱、鉄骨柱の周囲に配筋された鉄筋、及び鉄骨柱及び各鉄筋を覆う被覆コンクリートを有するプレキャスト部材からなる外周柱と、外周柱から建物内部方向に向けて架設される鉄骨造の内部梁と、を備える構成が開示されている。
特許文献3には、断面略長方形の扁平な壁柱と、壁柱に接合される鉄骨梁とを備え、壁柱は複数に分割された柱部材からなり、各柱部材が、プレキャストコンクリート造とされた構成が開示されている。
For example, Patent Literature 1 discloses that an outer peripheral column arranged at the position of an outer wall surface of a building, an outer peripheral beam installed between adjacent outer peripheral columns, and an outer peripheral column There is disclosed a configuration provided with an internal beam. In this configuration, the outer peripheral pillar is a steel-framed reinforced concrete wall pillar in which a wall-shaped coated concrete made of reinforced concrete is integrally formed around a core steel frame.
In addition, Patent Document 2 discloses a steel pillar, a steel pillar arranged around the steel pillar, an outer pillar made of a precast member having a steel pillar and a covering concrete covering each of the steel bars, and an outer pillar from the outer pillar toward the inside of the building. And a steel frame internal beam that is erected.
Patent Literature 3 includes a flat wall column having a substantially rectangular cross section and a steel beam joined to the wall column, and the wall column is composed of a plurality of divided column members, and each column member is made of precast concrete. A disclosed configuration is disclosed.

特許文献1〜3に開示されたような壁柱は、いずれも平断面視の形状が、建物の外周面に沿って長辺を有する長方形状であり、建物の外周面に直交する短辺方向に一定の厚さを有している。建物全体の外径寸法を大きくするのを抑えつつ、建物内の居室空間をさらに拡大することが常に望まれている。しかし、特許文献1〜3に開示されたような構成において、建物内の居室空間を拡大するため、建物の外周面に直交する方向における壁柱の厚さを小さくすると、壁柱の強度が低下する、という問題点があった。   The wall pillars disclosed in Patent Literatures 1 to 3 are all rectangular in plan view, have a rectangular shape having long sides along the outer peripheral surface of the building, and have a short side direction orthogonal to the outer peripheral surface of the building. Has a constant thickness. It is always desirable to further increase the living room space in a building while suppressing the increase in the outer diameter of the entire building. However, in the configurations disclosed in Patent Literatures 1 to 3, when the thickness of the wall pillar in the direction orthogonal to the outer peripheral surface of the building is reduced in order to enlarge the living room space in the building, the strength of the wall pillar is reduced. There was a problem that.

That is.

本発明者らは、SRC造の壁柱建物構造として、RC造の壁部と鉛直鉄骨材が埋設された鉛直柱型リブで構成される壁柱同士を鉄骨内部梁で連結して壁柱梁架構を形成し、当該壁柱梁架構を水平方向や鉛直方向に複数連結させることで、高い剛性と高い耐力を有する門型架構を構築できる点に着眼して、本発明に至った。
本発明は、上記課題を解決するため、以下の手段を採用する。
すなわち、本発明の鉄骨鉄筋コンクリート造の壁柱建物構造は、鉄骨鉄筋コンクリート造の壁柱と、当該壁柱に連結された鉄骨内部梁とを主体として構築された鉄骨鉄筋コンクリート造の壁柱建物構造であって、前記壁柱は、鉄骨鉛直材が配置された鉛直柱型リブと、縦筋、及び横筋が配筋された壁部とで構成されており、前記鉛直柱型リブと前記壁部は異なる壁厚さを備え、対向する前記壁柱の前記鉄骨鉛直材間に前記鉄骨内部梁が連結されて壁柱梁架構を形成し、当該壁柱梁架構が水平方向および/または鉛直方向に複数連結されることを特徴とする。
このような構成によれば、対向する壁柱の鉄骨鉛直材間に鉄骨内部梁を設けて、最小の立体抵抗体とする壁柱梁架構を形成し、当該壁柱梁架構を水平方向および/または鉛直方向に複数連結させて建物の骨組み架構を構築することで、壁柱の内部や壁柱の内外側面に梁部材を水平方向に設ける必要のない、鉄骨鉄筋コンクリート造の壁柱建物構造を実現した。本明細書では、本発明で形成される建物の骨組み架構を壁柱建物構造と定義した。よって、本発明の壁柱建物構造では、連結された壁柱同士が梁材の機能を有するために、壁柱の内部や壁柱の内外側面に梁材を設ける必要がなく、かつ、例えば壁部の壁厚さを鉛直柱型リブよりも薄くすることで、建物内の居室空間を拡大することを可能とした。
また、壁柱を構成する鉛直柱型リブ内に鉄骨鉛直材を配置することで、複数の鉛直方向鉄筋を間隔をあけて配筋する場合に比べて、同一の水平断面内に多くの鋼材量を配置することができるために、高剛性で高耐力の壁柱を確保することができる。
The present inventors have proposed an SRC wall column building structure in which a wall column composed of an RC wall and a vertical column type rib in which a vertical steel frame material is buried is connected to each other by a steel frame internal beam. The present invention has been achieved by forming a frame and connecting a plurality of the wall-column beams in a horizontal direction or a vertical direction to construct a portal frame having high rigidity and high strength.
The present invention employs the following means in order to solve the above problems.
That is, the steel reinforced concrete wall column building structure of the present invention is a steel reinforced concrete wall column building structure mainly composed of a steel reinforced concrete wall column and a steel internal beam connected to the wall column. The wall column is constituted by a vertical column-type rib on which a steel vertical member is arranged, and a wall portion on which vertical and horizontal streaks are arranged, and the vertical column-type rib and the wall portion are different. The steel frame internal beam is connected between the steel frame vertical members of the opposing wall columns having a wall thickness to form a wall column beam frame, and the wall column beam frame is connected in a plurality of horizontal and / or vertical directions. It is characterized by being performed.
According to such a configuration, a steel column internal beam is provided between the steel vertical members of the opposing wall columns to form a wall column beam frame serving as the smallest three-dimensional resistor, and the wall column beam frame is horizontally and / or horizontally. Or, by constructing a frame structure of the building by connecting multiple buildings in the vertical direction, it is possible to realize a steel reinforced concrete wall column building structure that does not require horizontal beam members inside the wall column and on the inside and outside surfaces of the wall column did. In this specification, the frame structure of the building formed by the present invention is defined as a wall column building structure. Therefore, in the wall column building structure of the present invention, since the connected wall columns have the function of a beam member, it is not necessary to provide a beam member inside the wall column or on the inner and outer surfaces of the wall column, and By making the wall thickness of the section thinner than the vertical pillar type rib, it was possible to expand the living room space in the building.
In addition, by arranging the vertical steel members in the vertical ribs that make up the wall columns, it is possible to use a large amount of steel in the same horizontal section compared to the case where multiple vertical reinforcing bars are arranged at intervals. Can be arranged, so that a wall column having high rigidity and high strength can be secured.

本発明の一態様においては、本発明の鉄骨鉄筋コンクリート造の壁柱建物構造は、前記壁部の壁厚さは、前記鉛直柱型リブの柱奥行き寸法より薄肉であり、前記壁部と前記鉛直柱型リブは建物外部側面が面一であることを特徴とする。

According to such a configuration, the wall thickness of the wall portion is made smaller than the column depth dimension of the vertical columnar rib, and the wall and the vertical columnar rib are made flush with the exterior side of the building. Since the frame thickness of the wall pillar projecting to the side is reduced, it is possible to expand the living room space in the building. In addition, since the outer wall surface of the building is flush with the vertical pillar-type ribs constituting the wall column, the outer wall surface has no irregularities, so that adhesion of dust and the like can be suppressed. In addition, on the outer wall surface of the building, there is no appearance of the vertical pillar-type ribs constituting the wall columns and the frame shape of the wall portion, and a building with a high degree of freedom in design can be realized.

本発明の一態様においては、本発明の鉄骨鉄筋コンクリート造の壁柱建物構造は、前記横筋の少なくとも一部は、前記鉄骨鉛直材を形成するウェブを貫通して、当該鉄骨鉛直材を挟んだ他方側の前記壁部内に定着されていることを特徴とする。
このような構成によれば、壁柱の平面視断面において、壁部を構成する横筋の少なくとも一部を、鉄骨鉛直材を挟んだ一方の壁部側から鉄骨鉛直材のウェブを貫通させて、他方の壁部内に定着させることで、横筋の定着性能を十分に確保することができる。これにより、横筋は、鉄骨鉛直材と干渉しない位置で、かつ鉄骨鉛直材に接する一方の壁部内に定着させる必要が無く、壁部の壁厚さを、鉛直柱型リブの柱奥行き寸法よりも容易に薄肉とし、さらに、鉄骨鉛直材のウェブを貫通させた横筋を介して壁部と鉛直柱型リブとを強固に一体化することができる。
In one aspect of the present invention, in the steel-framed reinforced concrete wall column building structure of the present invention, at least a part of the horizontal bar penetrates a web forming the steel frame vertical member, and sandwiches the steel frame vertical member. And is fixed in the wall portion on the side.

In the present embodiment, the horizontal streaks 27 are provided so as to be continuous throughout the width direction of the wall column 20 (the horizontal direction orthogonal to the thickness direction of the outer wall portion 11). That is, the horizontal streak 27 is provided so as to straddle the wall portion 22 located on one side in the width direction across the vertical column-shaped rib 21 and the wall portion 22 located on the other side in the width direction. Thereby, the horizontal streak 27 is provided to penetrate the vertical column-shaped rib 21 located between the wall portions 22 on both sides in the width direction in the horizontal direction. Here, the horizontal streak 27a on the outside of the building is arranged outside the flange 23b of the vertical steel frame member 23. The horizontal bars 27b on the inside of the building are arranged so as to penetrate the web 23a of the vertical steel frame member 23 in the horizontal direction.
The concrete portion 29 is provided so as to embed the horizontal streak 27 and the vertical streak 28. The concrete portions 29 of the wall portion 22 located on both sides in the width direction with the vertical column rib 21 interposed therebetween are formed integrally with the concrete portion 26 of the vertical column rib 21.

ここで、壁部22を構成するコンクリート部29は、図3に示すように、厚み方向(建物1の内外方向)の寸法(壁厚さ)T1が、鉛直柱型リブ21の厚み方向の寸法(柱奥行き寸法)T2よりも小さく設定されている。これにより、鉛直柱型リブ21は、壁部22に対し、建物1の内方に向かって突出している。このように、鉛直柱型リブ21と壁部22は、異なる壁厚さを備えている。
また、図2、図4に示されるように、壁柱20の幅方向両側の側端部において、コンクリート部29には、側端部傾斜面20sが形成されている。側端部傾斜面20sは、外壁部11の外壁面11f側から内壁面11g側に向かって、幅方向内側に向かって傾斜している。これにより、壁柱20を外壁部11に沿って水平方向に並べて配置したときに、互いに隣り合う壁柱20の側端部傾斜面20s同士の間に、平断面視三角形状の欠込み部S1が形成される。この欠込み部S1は、外壁部11の内壁面11g側から外壁面11f側に向かって、その開口幅寸法が漸次小さくなるよう形成されている。
図4に示されるように、側端部傾斜面20sには、外壁部11の厚み方向に延在する表面20uを備えた凹部20tが形成されている。壁部22には、壁部22の厚み方向のほぼ中央付近に、壁柱20の幅方向に延在するように、コッター筋31が設けられている。コッター筋31は、一端が壁部22のコンクリート部29に埋設され、他端が表面20uから外部へ突出するように設けられている。コッター筋31は、双方の壁部22に配筋された横筋27の鉄筋量相当を確保できるように、所定の鉄筋量を鉛直方向に間隔をあけて配筋する。あるいは、コッター筋31を、横筋27に比べて、高強度鉄筋または太径鉄筋を使用することで、1本の鉄筋の応力負担性能を高めて、本数を少なく配筋しても良い。
Here, as shown in FIG. 3, the dimension (wall thickness) T1 of the concrete portion 29 constituting the wall portion 22 in the thickness direction (inside and outside of the building 1) is the dimension of the vertical column-shaped rib 21 in the thickness direction. (Pole depth dimension) is set smaller than T2. Thus, the vertical column-shaped ribs 21 protrude toward the inside of the building 1 with respect to the wall 22. As described above, the vertical column rib 21 and the wall 22 have different wall thicknesses.
In addition, as shown in FIGS. 2 and 4, at the side end portions on both sides in the width direction of the wall column 20, a side end inclined surface 20 s is formed in the concrete portion 29.

The wall portion 22 is provided with a cotter streak 31 near the center of the wall portion 22 in the thickness direction so as to extend in the width direction of the wall post 20. The cotter streak 31 is provided so that one end is embedded in the concrete portion 29 of the wall portion 22 and the other end protrudes from the surface 20u to the outside. The cotter streaks 31 arrange a predetermined amount of the reinforcing bars at intervals in the vertical direction so as to secure the amount of the reinforcing bars of the horizontal streaks 27 arranged on both the wall portions 22. Alternatively, the cotter streaks 31 may be made of a high-strength reinforcing bar or a large-diameter reinforcing bar as compared with the horizontal bars 27, so that the stress-carrying performance of one reinforcing bar is increased, and the number of the bars is reduced.

また、壁柱20の下端部においては、図5に示すように、コンクリート部26の下端部には、上方に向かって窪む切り欠き部26kが形成されている。鉄骨鉛直材23および柱主筋24の下端部は、コンクリート部26から切り欠き部26k内に下方に突出している。また、鉄骨鉛直材23および柱主筋24の上端部は、コンクリート部26の上端面から上方に所定長が突出するように設けられている。

以下、本実施形態の鉄骨鉄筋コンクリート造の壁柱建物構造による作用効果を述べる。
上述したような鉄骨鉄筋コンクリート造の壁柱構造によれば、鉄骨鉄筋コンクリート造の壁柱20と、壁柱20に連結された鉄骨梁30とを主体として構築された鉄骨鉄筋コンクリート造の壁柱建物構造であって、壁柱20は、鉄骨鉛直材23が配置された鉛直柱型リブ21と、縦筋28、及び横筋27が配筋された壁部22とで構成されており、鉛直柱型リブ21と壁部22は異なる壁厚さを備え、対向する壁柱20の鉄骨鉛直材23間に内部梁が溶接されて壁柱梁架構10を形成し、壁柱梁架構10が水平方向および/または鉛直方向に複数連結される。
このような構成によれば、対向する壁柱20の鉄骨鉛直材23間に鉄骨内部梁30を設けて、最小の立体抵抗体とする壁柱梁架構10を形成し、当該壁柱梁架構10を水平方向および/または鉛直方向に複数連結させて建物の骨組み架構を構築することで、壁柱20の内部や壁柱20の内外側面に梁部材を水平方向に設ける必要のない、鉄骨鉄筋コンクリート造の壁柱建物構造を実現した。よって、本発明の壁柱建物構造では、連結された壁柱20同士が梁材の機能を有するために、壁柱20の内部、または壁柱20の表面に沿って梁材を設ける必要がなく、かつ、本実施形態のように壁部22の壁厚さを鉛直柱型リブ21よりも薄くすることで、建物内の居室空間を拡大することを可能とした。
また、壁柱20を構成する鉛直柱型リブ21内に鉄骨鉛直材23を配置することで、複数の鉛直方向鉄筋を間隔をあけて配筋する場合に比べて、同一の水平断面内に多くの鋼材量を配置することができるために、高剛性で高耐力の壁柱20を確保することができる。
Hereinafter, the operation and effect of the steel-framed reinforced concrete wall column building structure of the present embodiment will be described.
According to the above-described steel reinforced concrete wall column structure, a steel reinforced concrete wall column building structure mainly composed of a steel reinforced concrete wall column 20 and a steel beam 30 connected to the wall column 20 is used. The wall column 20 is composed of a vertical column-shaped rib 21 on which a steel frame vertical member 23 is arranged, and a wall portion 22 on which a vertical bar 28 and a horizontal bar 27 are arranged. And the wall portions 22 have different wall thicknesses, and the inner beams are welded between the steel vertical members 23 of the opposing wall columns 20 to form the wall column structures 10, and the wall column structures 10 are horizontally and / or horizontally. Multiple units are connected in the vertical direction.
According to such a configuration, the steel frame internal beam 30 is provided between the steel frame vertical members 23 of the opposing wall columns 20 to form the wall column beam frame 10 as the smallest three-dimensional resistor, and the wall column beam frame 10 is formed. Are connected in a horizontal direction and / or a vertical direction to construct a framework of a building, so that it is not necessary to provide a beam member horizontally in the interior of the wall column 20 or on the inner and outer surfaces of the wall column 20. The wall pillar building structure was realized. Therefore, in the wall pillar building structure of the present invention, since the connected wall pillars 20 have a beam function, there is no need to provide a beam material inside the wall pillar 20 or along the surface of the wall pillar 20. In addition, by making the wall thickness of the wall portion 22 smaller than that of the vertical column rib 21 as in the present embodiment, it is possible to enlarge the living room space in the building.
Further, by arranging the steel frame vertical members 23 in the vertical column-shaped ribs 21 constituting the wall columns 20, more steel bars are provided in the same horizontal section than in a case where a plurality of vertical reinforcing bars are arranged at intervals. Since the amount of steel material can be arranged, the wall column 20 having high rigidity and high proof strength can be secured.

また、壁部22の壁厚さは、鉛直柱型リブ21の柱奥行き寸法より薄肉であり、壁部22と鉛直柱型リブ21は建物外部側面が面一である。
このような構成によれば、壁部22の壁厚さを鉛直柱型リブ21の柱奥行き寸法よりも薄くし、かつ壁部22と鉛直柱型リブ21の建物外部側面を面一とすることで、建物内部側に突出する壁柱20の躯体厚さが薄くなるために、建物内の居室空間を拡大することが可能となる。また、建物外壁面は、壁柱20を構成する鉛直柱型リブ21と壁部22が面一であることで、外壁面に凹凸部はなく、粉塵等の付着を抑制できる。また、建物外壁面においては、壁柱20を構成する鉛直柱型リブ21や壁部22の躯体形状が現れることはなく、設計自由度の高い建物が実現可能である。
The wall thickness of the wall portion 22 is thinner than the column depth dimension of the vertical columnar rib 21, and the wall portion 22 and the vertical columnar rib 21 are flush with the outer side surface of the building.
According to such a configuration, the wall thickness of the wall portion 22 is made smaller than the column depth dimension of the vertical columnar rib 21, and the exterior side surface of the wall portion 22 and the vertical columnar rib 21 are flush with each other. Thus, since the frame thickness of the wall pillars 20 protruding toward the inside of the building is reduced, the living room space in the building can be expanded. In addition, the outer wall surface of the building has no unevenness on the outer wall surface since the vertical column ribs 21 and the wall portion 22 constituting the wall column 20 are flush with each other, so that adhesion of dust and the like can be suppressed. Further, on the outer wall surface of the building, the skeleton shape of the vertical column-shaped ribs 21 and the wall portions 22 constituting the wall columns 20 does not appear, and a building with a high degree of design freedom can be realized.

また、壁部内の横筋のうち、建物内部側に配筋される横筋27bは、鉄骨鉛直材23を形成するウェブ23aを貫通して、鉄骨鉛直材23を挟んだ他方側の壁部22内に定着されている。
このような構成によれば、壁柱20の平面視断面において、壁部22を構成する横筋27の少なくとも一部を、鉄骨鉛直材23を挟んだ一方の壁部22側から鉄骨鉛直材23のウェブ23aを貫通させて、他方の壁部22内に定着させることで、横筋27の定着性能を十分に確保することができる。これにより、横筋27は、鉄骨鉛直材23と干渉しない位置で、かつ鉄骨鉛直材23に接する一方の壁部22内に定着させる必要が無く、壁部22の壁厚さを、鉛直柱型リブ21の柱奥行き寸法よりも容易に薄肉とし、さらに、鉄骨鉛直材23のウェブ23aを貫通させた横筋27を介して壁部22と鉛直柱型リブ21とを強固に一体化することができる。
Of the horizontal bars in the wall, the horizontal bars 27b arranged on the inner side of the building penetrate the web 23a forming the steel frame vertical member 23, and are inserted into the wall 22 on the other side sandwiching the steel frame vertical member 23. Has been established.
According to such a configuration, in the cross section of the wall column 20 in a plan view, at least a part of the horizontal streak 27 forming the wall portion 22 is formed from the one wall portion 22 side with the steel frame vertical member 23 interposed therebetween. By penetrating the web 23a and fixing it in the other wall portion 22, the fixing performance of the horizontal streak 27 can be sufficiently ensured. Accordingly, the horizontal streak 27 does not need to be fixed at a position not interfering with the steel frame vertical member 23 and in one of the wall portions 22 in contact with the steel frame vertical member 23, and the wall thickness of the wall portion 22 is reduced by the vertical column rib. 21 can be made thinner than the depth of the column, and the wall 22 and the vertical column-type rib 21 can be firmly integrated via the horizontal bar 27 penetrating the web 23a of the steel vertical member 23.

また、上下方向に壁柱20を複数枚並べて積み重ねるときに、互いに上下に位置する壁柱20同士の接合部は、建物1の各階の上下方向中間部に位置するようになっている。
このような構成によれば、地震等による外力が作用したときの曲げ応力が小さくなる各階の上下方向中間部に壁柱20同士の接合部があるため、外力に効率的に抗し得る建物1を実現可能である。
Also, when a plurality of wall pillars 20 are arranged and stacked in the vertical direction, the joint between the wall pillars 20 located above and below each other is located at the middle part in the vertical direction of each floor of the building 1.
According to such a configuration, since the joint between the wall columns 20 is provided at the middle part in the vertical direction of each floor where the bending stress when an external force due to an earthquake or the like acts is small, the building 1 that can effectively withstand the external force Is feasible.

また、壁柱20は、外壁部11の面内方向に沿って延びる鉄骨梁を更に備えるようにしても良い。
また、上記実施形態では、壁柱同士の水平方向の接合方法は、図3に示すように、壁部22内に、横筋27とは別にコッター筋31を埋設し、コッター筋31同士を連結するとともに、壁柱20の水平接合面の欠込み部S1にコンクリートを充填して一体化したが、これに限られない。例えば、横筋として上記実施形態のような、縦筋28を外方から囲って閉鎖するものではなく、横方向に延在して壁部22の端部で終端するものを使用し、コッター筋31の代わりにこの横筋同士を機械式鉄筋継ぎ手治具で連結させても良い。
また、図10に示されるように、上方の壁柱20と下方の壁柱20が、フラットな接合目地部46を介して連結されていてもよい。
さらに、上記実施形態では、壁柱20を鉛直方向および水平方向に並べて設けることで、外壁部11を形成するようにしたが、壁柱20を上下方向のみに並べて設け、水平方向で互いに隣り合う壁柱20どうしは、梁部材で連結するようにしてもよい。
さらに、上記実施形態では、本発明に係る鉄骨鉄筋コンクリート造の壁柱建物構造の適用例として、建物1を例示したが、適用対象となる建物の形状、構成については、適宜変更することが可能である。
さらに、上記実施形態では、互いに上下に位置する壁柱20同士の接合部は、建物1の各階の上下方向中間部に位置するようになっていたが、これに限られない。例えば、中間部から上下方向に所定の距離だけ離れた位置において、曲げ応力がより小さくなるような設計がなされた場合等においては、当該位置に壁柱20同士の接合部が設けられる構造となっても構わない。
これ以外にも、本発明の主旨を逸脱しない限り、上記実施の形態及び変形例で挙げた構成を取捨選択したり、他の構成に適宜変更したりすることが可能である。
(Other Modifications of Embodiment)
It should be noted that the steel-framed reinforced concrete wall column building structure of the present invention is not limited to the above-described embodiment and modifications described with reference to the drawings, and various modifications are possible within the technical scope.
For example, in the above-described embodiment, the vertical column-shaped ribs 21 protrude inward of the building 1 with respect to the wall 22. However, the vertical column-shaped ribs 21 protrude outward of the building 1. You may do so.
Further, the wall column 20 may further include a steel beam extending along an in-plane direction of the outer wall portion 11.
Further, in the above-described embodiment, as shown in FIG. 3, in the method of joining the wall columns in the horizontal direction, the cotter streaks 31 are embedded in the wall portion 22 separately from the horizontal streaks 27 and the cotter streaks 31 are connected to each other. At the same time, the notch S1 of the horizontal joint surface of the wall column 20 is filled with concrete and integrated, but is not limited to this. For example, instead of using the horizontal streak as in the above-described embodiment, the vertical streak 28 is not surrounded from the outside and closed, but is used to extend in the horizontal direction and terminate at the end of the wall 22. Instead, the horizontal bars may be connected to each other by a mechanical reinforcing joint jig.
As shown in FIG. 10, the upper wall post 20 and the lower wall post 20 may be connected via a flat joint joint 46.
Furthermore, in the above embodiment, the outer wall portion 11 is formed by arranging the wall pillars 20 in the vertical direction and the horizontal direction, but the wall pillars 20 are arranged in the vertical direction only, and are adjacent to each other in the horizontal direction. The wall columns 20 may be connected by a beam member.
Further, in the above embodiment, the building 1 is exemplified as an application example of the steel-framed reinforced concrete wall-column building structure according to the present invention. However, the shape and configuration of the building to be applied can be appropriately changed. is there.
Furthermore, in the above-described embodiment, the joint between the wall pillars 20 located above and below each other is located at the middle part in the vertical direction of each floor of the building 1, but is not limited to this. For example, in a case where a design is made such that bending stress becomes smaller at a position vertically separated from the intermediate portion by a predetermined distance, a joint portion between the wall columns 20 is provided at the position. It does not matter.
Other than the above, the configurations described in the above-described embodiments and modified examples can be selected or changed to other configurations as appropriate without departing from the gist of the present invention.
