Description

本発明は屋外階段構造、及び屋外階段構造の設置方法に関する。 The present invention relates to an outdoor staircase structure and a method for installing the outdoor staircase structure.

従来、建造物の外側に設置される屋外階段としては、例えば特許文献1に示されるような階段が知られている。特許文献1に記載された階段は、建物本体の外側に一対の支持柱を立設するとともに、当該支持柱の両側の側面に支持梁を突設し、これらの支持梁を用いて踊場及び階段部を支持する構造とされている。 Conventionally, as an outdoor staircase installed on the outside of a building, for example, a staircase as shown in Patent Document 1 is known. In the stairs described in Patent Document 1, a pair of support columns are erected on the outside of the building body, and support beams are projected on both side surfaces of the support columns, and the landing and stairs are used by using these support beams. It is a structure that supports the part.

The arrangement direction of the outdoor staircase structure 1 with respect to the building is not limited to the illustrated example, and the side surface opposite to the example of FIG. 1 may be arranged so as to be the building side, or the main landing 4 side or the intermediate landing. It may be arranged so that the 5 side is the building side.

下側階段部7及び上側階段部8は、階段支持部によって支持される。本例の階段支持部は、下側階段部7及び上側階段部8の下方に位置する支持梁9(第1支持梁9a、第2支持梁9b)と、梁勝ち状態で支持梁9に接続される支持柱10(第1支持柱10a、第2支持柱10b)とを備える。なお、階段支持部は、第1支持梁9aと第2支持梁9bとの間に接続される補強部材等の、他の部材を備えていてもよい。 The lower staircase portion 7 and the upper staircase portion 8 are supported by the staircase support portion. The staircase support portion of this example is connected to the support beam 9 (first support beam 9a, second support beam 9b) located below the lower staircase portion 7 and the upper staircase portion 8 and the support beam 9 in a beam-winning state. A support column 10 (first support column 10a, second support column 10b) is provided. The staircase support portion may include other members such as a reinforcing member connected between the first support beam 9a and the second support beam 9b.

Further, the elevating part 6 between the first landing part 7a and the second landing part 7b is provided with a tread portion 7c and a riser portion 7d. Further, the lower staircase portion 7 includes left and right girder portions 7e extending substantially in parallel, and left and right handrail portions 7f that also serve as a fall prevention fence. The lower staircase portion 7 can be a staircase unit member unitized by assembling the constituent members in advance at a factory or the like.

上側階段部8は、上部に設けられた踊場構成部8aと、下部に設けられた踊場構成部8bとを有する。踊場構成部8a、8bは全体として平坦な部分であるが、一部に段差等の凹凸が形成されていてもよい。また、踊場構成部8aと踊場構成部8bとの間には、昇降部6を構成する踏み面部8c及び蹴込み部8dが設けられている。さらに、上側階段部8は、略平行に延在する左右の桁部8eと、落下防止柵を兼ねた左右の手摺部8fとを備える。下側階段部8は、各部を構成する部材を予め組み付けてユニット化された階段ユニット部材とすることができる。なお、下側階段部7と上側階段部8は、同一形状の共通部材としてもよいし、異なる形状でもよい。また、下側階段部7と上側階段部8の構成は図示例に限定されるものではない。例えば桁部7e、8eは図示のような側桁に限らず、ささら桁であってもよいし、また、蹴込み部7d、8dを有していない構造であってもよい。 The upper staircase portion 8 has a landing configuration portion 8a provided at the upper portion and a landing configuration portion 8b provided at the lower portion. The landing components 8a and 8b are flat portions as a whole, but unevenness such as a step may be formed in a part thereof. Further, between the landing section 8a and the landing section 8b, a tread portion 8c and a riser portion 8d constituting the elevating section 6 are provided. Further, the upper staircase portion 8 includes left and right girder portions 8e extending substantially in parallel, and left and right handrail portions 8f that also serve as a fall prevention fence. The lower staircase portion 8 can be made into a unitized staircase unit member by assembling the members constituting each portion in advance. The lower staircase portion 7 and the upper staircase portion 8 may have the same shape as a common member or may have different shapes. Further, the configurations of the lower staircase portion 7 and the upper staircase portion 8 are not limited to the illustrated examples. For example, the girder portions 7e and 8e are not limited to the side girders as shown in the figure, and may be a sasara girder, or may have a structure that does not have the riser portions 7d and 8d.

下側階段部7の第1踊場構成部7aが中間踊場5の一方側の半部を構成し、上側階段部8の第2踊場構成部8bが、中間踊場5の他方側の半部を構成する。同様に、主踊場4の一方側の半部は、下側階段部7の第2踊場構成部7bで構成され、他方側の半部は、上側階段部8の第1踊場構成部8aで構成される。 The first landing component 7a of the lower staircase 7 constitutes one half of the intermediate landing 5, and the second landing component 8b of the upper staircase 8 constitutes the other half of the intermediate landing 5. do. Similarly, one half of the main landing 4 is composed of the second landing component 7b of the lower staircase 7, and the other half is composed of the first landing component 8a of the upper staircase 8. Will be done.

中間踊場5側に位置する下側階段部7の上部(本例では第1踊場構成部7a)と上側階段部8の下部(本例では第2踊場構成部8b)は、第1支持梁9aによって支持され、第1支持梁9aは第1支持柱10aによって支持される。一方で、主踊場4側に位置する下側階段部7の下部(本例では第2踊場構成部7b)と上側階段部8の上部(本例では第1踊場構成部8a)は第2支持梁9bによって支持され、第2支持梁9bは第2支持柱10bによって支持される。本例では、第1踊場構成部7aと第2踊場構成部8bは、第1支持梁9aの上方に配置され、ボルトにより固定され、同様に第2踊場構成部7bと第1踊場構成部8aは、第2支持梁9bの上方に配置され、ボルトにより固定されるが、支持梁9に対する階段部(下側階段部7及び上側階段部8)の固定方法はこれに限定されない。 The upper part of the lower staircase portion 7 (in this example, the first landing part 7a) and the lower part of the upper staircase part 8 (in this example, the second landing part 8b) located on the intermediate landing 5 side are the first support beams 9a. The first support beam 9a is supported by the first support column 10a. On the other hand, the lower part of the lower staircase 7 located on the main landing 4 side (the second landing part 7b in this example) and the upper part of the upper staircase 8 (the first landing part 8a in this example) are the second supporters. It is supported by the beam 9b, and the second support beam 9b is supported by the second support column 10b. In this example, the first landing component 7a and the second landing component 8b are arranged above the first support beam 9a and fixed by bolts, and similarly, the second landing component 7b and the first landing component 8a Is placed above the second support beam 9b and fixed by bolts, but the method of fixing the stairs (lower stairs 7 and upper stairs 8) to the support beam 9 is not limited to this.

第1支持梁9aと第2支持梁9bは相互に平行で、異なる高さに配置される。また、中間踊場5側の第1支持柱10a及び主踊場4側の第2支持柱10bは、下側階段部7と上側階段部8との間の隙間に配置される。 The first support beam 9a and the second support beam 9b are parallel to each other and are arranged at different heights. Further, the first support pillar 10a on the intermediate landing 5 side and the second support pillar 10b on the main landing 4 side are arranged in the gap between the lower staircase portion 7 and the upper staircase portion 8.

本例の第1支持梁9a及び第2支持梁9bは、H形鋼の一方のフランジの上面に、階段部接続用の接続板部11を設けるとともに、接続板部11に対応する位置において、対向する一対のフランジ間に補強板部12を溶接したものである。部材を共通化する観点から、第1支持梁9aと第2支持梁9bとが同一の部材であることが好ましいが、形状の異なる部材であってもよい。 In the first support beam 9a and the second support beam 9b of this example, a connection plate portion 11 for connecting a staircase portion is provided on the upper surface of one flange of the H-shaped steel, and at a position corresponding to the connection plate portion 11. The reinforcing plate portion 12 is welded between a pair of facing flanges. From the viewpoint of sharing the members, it is preferable that the first support beam 9a and the second support beam 9b are the same member, but members having different shapes may be used.

第1支持柱10aは、第1支持梁9aの下側に梁勝ち状態で接続され、当該第1支持梁9aを支持する。ここで、「梁勝ち状態で接続される」とは、支持梁9と支持柱10の接続部において、支持梁9が連続性を維持するように支持梁9の上面側又は下面側に支持柱10が接続されることを意味する。なお、支持梁9と支持柱10は直接結合されていてもよいし、接続金物等の他の部材を間に介して接続されていていてもよい。最上階の支持梁9を除いて、支持梁9の上面側には、上階の支持梁9を支持する支持柱10が梁勝ち状態で接続される。 The first support column 10a is connected to the lower side of the first support beam 9a in a beam-winning state, and supports the first support beam 9a. Here, "connected in a beam-winning state" means that at the connection portion between the support beam 9 and the support column 10, the support column is on the upper surface side or the lower surface side of the support beam 9 so that the support beam 9 maintains continuity. It means that 10 is connected. The support beam 9 and the support pillar 10 may be directly connected to each other, or may be connected to each other via other members such as connecting hardware. Except for the support beam 9 on the top floor, the support pillar 10 that supports the support beam 9 on the upper floor is connected to the upper surface side of the support beam 9 in a beam-winning state.

第1支持柱10a及び第2支持柱10bは、軸方向の一端部に設けられた柱頭部13と、他端部に設けられた柱脚部14とを有する。なお、本例の第1支持柱10a及び第2支持柱10bは、柱頭部13と柱脚部14の形状を共通化しているため、上下反転しても使用可能となっている。また、部材を共通化する観点から、第1支持柱10aと第2支持柱10bとは、同一の部材であることが好ましいが、形状の異なる部材としてもよい。 The first support column 10a and the second support column 10b have a stigma 13 provided at one end in the axial direction and a column base 14 provided at the other end. Since the first support column 10a and the second support column 10b of this example have the same shape of the stigma 13 and the column base 14, they can be used even if they are turned upside down. Further, from the viewpoint of sharing the members, the first support column 10a and the second support column 10b are preferably the same member, but may be members having different shapes.

柱頭部13及び柱脚部14は、支持梁9に対して支持柱10をボルト接合により接続するための接続部となっている。具体的に、柱頭部13及び柱脚部14は、横断面が略十字状の軸部15と、支持柱10の軸線方向に対して垂直に延在する板部16と、を有する。板部16には、支持柱10の軸線方向から見て支持柱10の外面輪郭線よりも内側に位置するボルト貫通用の孔17が形成されている(図3B参照)。このように、ボルト貫通用の孔17が支持柱10の軸線方向から見て支持柱10の外面輪郭線よりも内側に位置することで、ボルトが支持柱10の外側に突出しないため、他の部材に干渉し難く、また、外観的にも優れたものとすることができる。 The stigma 13 and the pedestal 14 are connecting portions for connecting the support columns 10 to the support beams 9 by bolt joining. Specifically, the stigma 13 and the pedestal 14 have a shaft portion 15 having a substantially cross-shaped cross section and a plate portion 16 extending perpendicular to the axial direction of the support column 10. The plate portion 16 is formed with a hole 17 for bolt penetration located inside the outer contour line of the support column 10 when viewed from the axial direction of the support column 10 (see FIG. 3B). In this way, since the hole 17 for penetrating the bolt is located inside the contour line of the outer surface of the support column 10 when viewed from the axial direction of the support column 10, the bolt does not protrude to the outside of the support column 10, so that the other It does not easily interfere with the members and can be excellent in appearance.

図3Aは、支持梁9と支持柱10の柱脚部14(または柱頭部13)との接続部を拡大して示した斜視図である。図3Bは、軸部15において軸線方向に垂直に切断した場合の、支持柱10の軸線方向から見た断面図である。図3Aに示すように、支持梁9の上面に支持柱10を垂直に突き当てるように配置した状態で、支持梁9の上面(または下面)に板部16を当接させ、板部16の孔17を通して支持梁9の上面(または下面)に形成された雌ねじ付きのボルト孔にボルトを締結することにより、支持梁9と支持柱10とを接続することができる。あるいは、板部16の孔17と支持梁9に形成された貫通孔を通してボルトとナットで締結してもよい。 FIG. 3A is an enlarged perspective view showing a connection portion between the support beam 9 and the column base portion 14 (or the stigma 13) of the support column 10. FIG. 3B is a cross-sectional view of the support column 10 as viewed from the axial direction when the shaft portion 15 is cut perpendicular to the axial direction. As shown in FIG. 3A, the plate portion 16 is brought into contact with the upper surface (or lower surface) of the support beam 9 in a state where the support pillar 10 is vertically abutted against the upper surface of the support beam 9, and the plate portion 16 is formed. The support beam 9 and the support column 10 can be connected by fastening a bolt to a bolt hole with a female thread formed on the upper surface (or lower surface) of the support beam 9 through the hole 17. Alternatively, the holes 17 of the plate portion 16 and the through holes formed in the support beam 9 may be fastened with bolts and nuts.

なお、支持梁9と支持柱10との接続方法はこれに限定されず、柱の軸力とせん断力を十分に伝達できれば、例えば、図4A、4B、及び図5、6に示す方法でもよい。図4A、4Bは、支持柱10がH形鋼である場合の接続部の一例を示す斜視図及び断面図である。支持柱10の先端に溶接した板部16には、ボルト貫通用の孔17が形成されており、板部16が、図3A、3Bに示す場合と同様に、支持梁9の上面(又は下面)にボルト接合される。なお、図4Bに示すように、4つの孔17は、支持柱10の軸線方向から見て支持柱10の外面輪郭線(H形鋼の最大幅位置及び最大奥行位置)よりも内側に位置している。 The method of connecting the support beam 9 and the support column 10 is not limited to this, and the methods shown in FIGS. 4A and 4B and FIGS. 5 and 6 may be used as long as the axial force and the shear force of the column can be sufficiently transmitted. .. 4A and 4B are perspective views and cross-sectional views showing an example of a connecting portion when the support column 10 is made of H-shaped steel. A hole 17 for bolt penetration is formed in the plate portion 16 welded to the tip of the support column 10, and the plate portion 16 has an upper surface (or lower surface) of the support beam 9 as in the case shown in FIGS. 3A and 3B. ) Is bolted. As shown in FIG. 4B, the four holes 17 are located inside the outer contour line (maximum width position and maximum depth position of the H-shaped steel) of the support column 10 when viewed from the axial direction of the support column 10. ing.

図5、図6は、支持梁9と支持柱10の接続部において、ボルト用の孔17が支持柱10の外面輪郭線よりも外側に位置する例を示す斜視図である。図5に示すように、断面がL型の接続金物18を用いて、支持梁9と支持柱10を接続してもよい。図5に示す支持柱10は角形鋼管であり、支持柱10の両側面に接するように接続金物18を配置して、ボルト及びナットで支持柱10と当該接続金物18を両側から挟んで締結するようにしている。また、それぞれの接続金物18は支持梁9の上面(または下面)にボルト接合される。 5 and 6 are perspective views showing an example in which the holes 17 for bolts are located outside the outer contour line of the support pillar 10 at the connection portion between the support beam 9 and the support pillar 10. As shown in FIG. 5, the support beam 9 and the support column 10 may be connected by using a connecting metal fitting 18 having an L-shaped cross section. The support column 10 shown in FIG. 5 is a square steel pipe, and the connection hardware 18 is arranged so as to be in contact with both side surfaces of the support column 10, and the support column 10 and the connection hardware 18 are sandwiched and fastened from both sides with bolts and nuts. I am doing it. Further, each connecting metal fitting 18 is bolted to the upper surface (or lower surface) of the support beam 9.

図6に示す例では、支持柱10の先端に溶接した板部16にボルト用の孔17が形成されており、板部16を支持梁9の上面(または下面)に当接させて、ボルト接合している。何れの場合にも、支持梁9と支持柱10とを梁勝ち状態で接続することができる。 In the example shown in FIG. 6, a hole 17 for a bolt is formed in a plate portion 16 welded to the tip of a support column 10, and the plate portion 16 is brought into contact with the upper surface (or lower surface) of the support beam 9 to be bolted. It is joined. In either case, the support beam 9 and the support column 10 can be connected in a beam-winning state.

中間踊場5側を支持する第1支持梁9a及び主踊場4側を支持する第2支持梁9bは、建造物の躯体に接続されていることが好ましい。本例の第1支持梁9aは、上下に隣接する梁2の間に設けられた間柱3に接続されている。間柱3と第1支持梁9aとの接続は、特に限定されないが、例えば、間柱3に予め溶接又はボルト接合された板状の接続金物3a(ブラケット)に対して、第1支持梁9aの端部をボルト接合することによって行うことができる。また、主踊場4側の第2支持梁9bは、梁2に接続されている。梁2と第2支持梁9bとの接続は、特に限定されないが、例えば、梁2に溶接された板状の接続金物(図示省略)に対して、第2支持梁9bをボルト接合することによって行うことができる。このような構成により、屋外階段構造1で生じる水平方向の力を建造物の躯体で受けることができるため、屋外階段構造1の安定性を向上させ、地震発生時等における横揺れを低減することができる。 It is preferable that the first support beam 9a supporting the intermediate landing 5 side and the second support beam 9b supporting the main landing 4 side are connected to the frame of the building. The first support beam 9a of this example is connected to a stud 3 provided between the vertically adjacent beams 2. The connection between the stud 3 and the first support beam 9a is not particularly limited, but for example, the end of the first support beam 9a is attached to a plate-shaped connecting metal fitting 3a (bracket) previously welded or bolted to the stud 3. This can be done by bolting the parts together. Further, the second support beam 9b on the main landing 4 side is connected to the beam 2. The connection between the beam 2 and the second support beam 9b is not particularly limited, but for example, by bolting the second support beam 9b to a plate-shaped connecting metal fitting (not shown) welded to the beam 2. It can be carried out. With such a configuration, the horizontal force generated by the outdoor staircase structure 1 can be received by the building frame, so that the stability of the outdoor staircase structure 1 can be improved and the rolling motion at the time of an earthquake or the like can be reduced. Can be done.

以下に、屋外階段構造1の設置方法について説明する。先ず、基礎梁(図示省略)に対して、第1支持柱10aの柱脚部14を固定して第1支持柱10aを鉛直に立設する。次いで、第1支持柱10aの上面に第1支持梁9aを積置し、柱頭部13と第1支持梁9aの下面とをボルト接合により固定することにより、第1支持柱10aと第1支持梁9aとを梁勝ち状態で接続する。さらに第1支持梁9aの端部を、間柱3にボルト接合により接続する。次いで、第1支持梁9aの上方に下側階段部7の第1踊場構成部7aを配置して、第1支持梁9aの接続板部11と第1踊場構成部7aとをボルト接合により固定する。これにより、第1支持柱10aと第1支持梁9aと下側階段部7とでトラス状態が形成されて架構が安定する。なお、第1支持柱10aと第1支持梁9aとは剛接合としなくても、トラス状態によって架構が安定する。 The installation method of the outdoor staircase structure 1 will be described below. First, the column base portion 14 of the first support column 10a is fixed to the foundation beam (not shown), and the first support column 10a is erected vertically. Next, the first support beam 9a is stacked on the upper surface of the first support column 10a, and the stigma 13 and the lower surface of the first support beam 9a are fixed by bolting to the first support column 10a and the first support. The beam 9a is connected in a beam-winning state. Further, the end portion of the first support beam 9a is connected to the stud 3 by bolt joining. Next, the first landing component 7a of the lower staircase portion 7 is arranged above the first support beam 9a, and the connection plate portion 11 of the first support beam 9a and the first landing component 7a are fixed by bolt joining. do. As a result, a truss state is formed by the first support column 10a, the first support beam 9a, and the lower staircase portion 7, and the frame is stabilized. Even if the first support column 10a and the first support beam 9a are not rigidly joined, the frame is stabilized depending on the truss state.

次いで、第1支持柱10a及び第1支持梁9aから所定の間隔を空けて、当該第1支持柱10a及び第1支持梁9aと同様に、第2支持柱10b及び第2支持梁9bを設置する。また、第2支持梁9bを、梁2にボルト接合により接続する。そして、第1支持梁9aの上方に上側階段部8の第2踊場構成部8bを配置し、第2支持梁9bの上方に当該上側階段部8の第1踊場構成部8aを配置するようにして、上側階段部8を第1支持梁9a及び第2支持梁9bの接続板部11にボルト接合により固定する。これにより、第2支持柱10bと第2支持梁9bと上側階段部8とでトラス状態が形成されて架構が安定する。支持梁9(第1支持梁9a及び第2支持梁9b)に対する下側階段部7及び上側階段部8の固定は、上述のように支持梁9の接続板部11に形成された貫通孔を利用したボルト接合により行うことができるが、これに限られない。 Next, the second support column 10b and the second support beam 9b are installed in the same manner as the first support column 10a and the first support beam 9a at predetermined intervals from the first support column 10a and the first support beam 9a. do. Further, the second support beam 9b is connected to the beam 2 by bolt joining. Then, the second landing component 8b of the upper staircase 8 is arranged above the first support beam 9a, and the first landing component 8a of the upper staircase 8 is arranged above the second support beam 9b. Then, the upper staircase portion 8 is fixed to the connection plate portion 11 of the first support beam 9a and the second support beam 9b by bolt joining. As a result, a truss state is formed by the second support column 10b, the second support beam 9b, and the upper staircase portion 8, and the frame is stabilized. The lower staircase portion 7 and the upper staircase portion 8 are fixed to the support beam 9 (first support beam 9a and second support beam 9b) by forming a through hole formed in the connection plate portion 11 of the support beam 9 as described above. It can be done by the bolt joining used, but it is not limited to this.

次いで、既設した下階の第1支持梁9aの上面側に、上階の第1支持柱10aを梁勝ち状態で接続し、当該第1支持柱10aの上方に上階の第1支持梁9aを固定する。そして、既設した第2支持梁9bと上階の第1支持梁9aの上方に上階の下側階段部7を配置し、固定する。これにより、上階の第1支持柱10aと上階の第1支持梁9aと上階の下側階段部7とでトラス状態が形成されて架構が安定する。これを繰り返すことにより、下方側から階層毎に屋外階段構造1を設置することができる。すなわち、例えば複数階層にわたって延在する長い支持柱を使用する場合のように、大掛かりな足場等の設備が不要となり、また、建造物を建築する過程で使用可能な仮設階段としても利用可能となる。なお、第1支持梁9aに生じる負荷を軽減する観点から、下階の第1支持柱10aと上階の第1支持柱10aとは、軸線が同一直線上に位置するように配置されることが好ましいが、これに限られない。同様に、下階の第2支持柱10bと上階の第2支持柱10bも軸線が一致するように配置されることが好ましいが、これに限られない。 Next, the first support pillar 10a on the upper floor is connected to the upper surface side of the existing first support beam 9a on the lower floor in a beam-winning state, and the first support beam 9a on the upper floor is connected above the first support pillar 10a. To fix. Then, the lower staircase portion 7 on the upper floor is arranged and fixed above the existing second support beam 9b and the first support beam 9a on the upper floor. As a result, a truss state is formed by the first support column 10a on the upper floor, the first support beam 9a on the upper floor, and the lower staircase portion 7 on the upper floor, and the frame is stabilized. By repeating this, the outdoor staircase structure 1 can be installed for each floor from the lower side. That is, equipment such as large-scale scaffolding becomes unnecessary, as in the case of using long support columns extending over multiple floors, and it can also be used as a temporary staircase that can be used in the process of building a building. .. From the viewpoint of reducing the load generated on the first support beam 9a, the first support pillar 10a on the lower floor and the first support pillar 10a on the upper floor are arranged so that their axes are located on the same straight line. Is preferable, but the present invention is not limited to this. Similarly, it is preferable that the second support pillar 10b on the lower floor and the second support pillar 10b on the upper floor are arranged so that the axes coincide with each other, but the present invention is not limited to this.

また、本実施形態によれば、下階の第1支持柱10aと上階の第1支持柱10aとの間に、第1支持梁9aが位置することになるため、上下の第1支持柱10a同士を直接連結する作業が不要となる。そのため、支持柱10の溶接または高力ボルトによる柱継ぎが不要となり、現場での施工作業が容易となる。また、支持柱10の側面に支持梁9を接続するための持ち出し梁やブラケット等の構成が不要となるため、支持柱10の運送効率の悪化も抑制することができる。 Further, according to the present embodiment, since the first support beam 9a is located between the first support pillar 10a on the lower floor and the first support pillar 10a on the upper floor, the upper and lower first support pillars are located. The work of directly connecting the 10a to each other becomes unnecessary. Therefore, it is not necessary to weld the support columns 10 or join columns with high-strength bolts, which facilitates on-site construction work. Further, since it is not necessary to configure a carry-out beam, a bracket, or the like for connecting the support beam 9 to the side surface of the support pillar 10, it is possible to suppress deterioration of the transportation efficiency of the support pillar 10.

図2は、本発明の他の実施形態としての屋外階段構造20を示している。屋外階段構造20が設置される建造物の躯体は柱21と、一対の柱21間に接続された梁22とを備えている。 FIG. 2 shows an outdoor staircase structure 20 as another embodiment of the present invention. The skeleton of the building in which the outdoor staircase structure 20 is installed includes a pillar 21 and a beam 22 connected between the pair of pillars 21.

屋外階段構造20は、図1に示す先の実施形態と構成が同様であり、左右反転した下側階段部7と上側階段部8とを備える。 The outdoor staircase structure 20 has the same configuration as the previous embodiment shown in FIG. 1, and includes a left-right inverted lower staircase portion 7 and an upper staircase portion 8.

また、屋外階段構造20は、建造物から離間する側に位置する中間踊場5側の第1支持梁9c及び左右一対の第1支持柱10cと、建造物の柱21に固定された持ち出し梁23に接続された主踊場4側の第2支持梁9dと、を備える。また、屋外階段構造20には、第1支持梁9cの両端部と、持ち出し梁23とを接続する補強部材24が設けられている。なお、本例の持ち出し梁23は、建造物の柱21に固定されているが、これに限られず、建造物の梁22に固定されていてもよい。 Further, the outdoor staircase structure 20 includes a first support beam 9c on the intermediate landing 5 side located on the side away from the building, a pair of left and right first support pillars 10c, and a carry-out beam 23 fixed to the pillar 21 of the building. It is provided with a second support beam 9d on the side of the main landing 4 connected to the main landing. Further, the outdoor staircase structure 20 is provided with reinforcing members 24 for connecting both ends of the first support beam 9c and the take-out beam 23. The carry-out beam 23 of this example is fixed to the pillar 21 of the building, but the present invention is not limited to this, and the carry-out beam 23 may be fixed to the beam 22 of the building.

図1に示す先の実施形態では、主踊場4側及び中間踊場5側がともに、支持梁9及び支持柱10によって支持される構成としているが、本実施形態では、下側階段部7と上側階段部8の主踊場4側を建造物側の躯体(梁22に固定された持ち出し梁23)で支持する構成としている。これにより、主踊場4側の安定性を高めることができる。 In the previous embodiment shown in FIG. 1, both the main landing 4 side and the intermediate landing 5 side are supported by the support beam 9 and the support pillar 10, but in the present embodiment, the lower staircase portion 7 and the upper staircase portion 7 are supported. The main landing 4 side of the part 8 is supported by the skeleton on the building side (the carry-out beam 23 fixed to the beam 22). This makes it possible to improve the stability of the main landing 4 side.

また、屋外階段構造20は、図1に示す先の実施形態では、下側階段部7と上側階段部8との間の隙間に、第1支持柱10a及び第2支持柱10bが配置される構成としていたが、本例では、一対の第1支持柱10cが下側階段部7と上側階段部8の外側にそれぞれ配置されている。このように、下側階段部7と上側階段部8を外側から挟むように一対の支持柱を設けることにより、安定性を高めることができる。なお、下側階段部7と上側階段部8との間の隙間に第1支持梁9cを支持する支持柱10を1本のみ、または複数本設けるようにしてもよい。 Further, in the outdoor staircase structure 20, in the above embodiment shown in FIG. 1, the first support pillar 10a and the second support pillar 10b are arranged in the gap between the lower staircase portion 7 and the upper staircase portion 8. However, in this example, a pair of first support columns 10c are arranged outside the lower staircase portion 7 and the upper staircase portion 8, respectively. In this way, by providing a pair of support columns so as to sandwich the lower staircase portion 7 and the upper staircase portion 8 from the outside, stability can be improved. In addition, only one or a plurality of support columns 10 for supporting the first support beam 9c may be provided in the gap between the lower staircase portion 7 and the upper staircase portion 8.

屋外階段構造20において、一対の第1支持柱10cは、それぞれ第1支持梁9cに対して梁勝ち状態で接続されているため、先の実施形態と同様に、第1支持柱10c同士を上下に直接連結する作業が不要となる。そのため、溶接または高力ボルトによる柱継ぎが不要となり、現場での施工作業が容易となる。また、第1支持柱10cの側面に第1支持梁9cを接続するための持ち出し梁やブラケット等の構成が不要となるため、第1支持柱10cの運送効率の悪化も抑制することができる。また、本例の屋外階段構造20においても各部材を階層毎に設置することができるため、施工が容易であり、仮設階段としても利用可能である。また、建物を下層から順に施工する場合には、建物の施工進捗に合わせて階段を設置することができるため、階段の支柱だけ突出してそのための安全対策をする必要がない。 In the outdoor staircase structure 20, since the pair of first support columns 10c are connected to the first support beam 9c in a beam-winning state, the first support columns 10c move up and down as in the previous embodiment. There is no need to connect directly to. Therefore, welding or column jointing with high-strength bolts becomes unnecessary, and on-site construction work becomes easy. Further, since it is not necessary to configure a carry-out beam, a bracket, or the like for connecting the first support beam 9c to the side surface of the first support pillar 10c, deterioration of the transportation efficiency of the first support pillar 10c can be suppressed. Further, also in the outdoor staircase structure 20 of this example, since each member can be installed for each layer, the construction is easy and the staircase can be used as a temporary staircase. Further, when the buildings are constructed in order from the lower layer, the stairs can be installed according to the progress of the construction of the building, so that it is not necessary to project only the columns of the stairs and take safety measures for that purpose.

また、上述のように、屋外階段構造20は、主踊場4側が建造物に面しており、中間踊場5側が建物から突出しているため、中間踊場5側が安定し難いところ、左右一対の第1支持柱10cを設けることにより、安定性を向上させている。さらに、建造物躯体側の持ち出し梁23と第1支持梁9cとを補強部材24を設けることにより、中間踊場5側の安定性をより効果的に高めることができる。 Further, as described above, in the outdoor staircase structure 20, the main landing 4 side faces the building and the intermediate landing 5 side protrudes from the building, so that the intermediate landing 5 side is difficult to stabilize. Stability is improved by providing the support column 10c. Further, by providing the reinforcing member 24 for the carry-out beam 23 on the building frame side and the first support beam 9c, the stability on the intermediate landing 5 side can be more effectively enhanced.

本発明に係る建物は、上述した実施形態の構成に限定されるものではなく、特許請求の範囲で記載された内容を逸脱しない範囲で、様々な構成により実現することが可能である。例えば、支持梁9及び支持柱10の形状は、上述の例に限定されず、種々の形鋼もしくは木材等の柱状部材を用いることができる。また、図1に示す屋外階段構造1では、1本の支持梁9(第1支持梁9aまたは第2支持梁9b)に掛かる鉛直荷重を1本の支持柱10(第1支持柱10aまたは第2支持柱10b)で受ける構成としているが、それぞれの支持梁9に複数本の支持柱10を接続して、当該複数本の支持柱10で鉛直荷重を受けるようにしてもよい。 The building according to the present invention is not limited to the configuration of the above-described embodiment, and can be realized by various configurations without departing from the contents described in the claims. For example, the shapes of the support beam 9 and the support column 10 are not limited to the above examples, and various columnar members such as shaped steel or wood can be used. Further, in the outdoor staircase structure 1 shown in FIG. 1, a vertical load applied to one support beam 9 (first support beam 9a or second support beam 9b) is applied to one support column 10 (first support column 10a or first support column 10a or second support column 9b). Although it is configured to be received by the two support columns 10b), a plurality of support columns 10 may be connected to each support beam 9 so that the plurality of support columns 10 receive a vertical load.

また、屋外階段構造20では、主踊場4側の鉛直方向荷重を建造物の躯体側で支持する構成としているが、階段支持部を構成する支持柱10で主踊場4側の鉛直方向荷重を受ける構成としてもよい。すなわち、例えば、中間踊場5側と同様に一対の支持柱10を第2支持梁9dに接続して、当該一対の支持柱10で主踊場4側の鉛直荷重を受ける構成としてもよい。 Further, in the outdoor staircase structure 20, the vertical load on the main landing 4 side is supported on the skeleton side of the building, but the support pillar 10 constituting the staircase support portion receives the vertical load on the main landing 4 side. It may be configured. That is, for example, a pair of support columns 10 may be connected to the second support beam 9d as in the intermediate landing 5 side, and the pair of support columns 10 may be configured to receive a vertical load on the main landing 4 side.
