Description

本発明は、屋外に面した階段を有する屋外階段付き建物に関するものである。   The present invention relates to a building with an outdoor staircase having a staircase facing the outdoors.

従来、この種の屋外階段付き建物としては、例えば特許文献１に示されるような建物が知られている。特許文献１の屋外階段付き建物は、最上階の屋根が陸屋根であって、最上階に設けたベランダとこの陸屋根とを連絡する屋外階段を設けて、陸屋根に登ることができるようにしている。   Conventionally, as this kind of building with an outdoor staircase, for example, a building as shown in Patent Document 1 is known. In the building with an outdoor staircase of Patent Document 1, the roof on the top floor is a flat roof, and an outdoor staircase that connects the veranda provided on the top floor with the land roof is provided so that the roof can be climbed.

特開２０００−６４６３６号公報JP 2000-64636 A

しかしながら、従来の屋外階段付き建物は、陸屋根に登ることができるとはいっても使用頻度がそれ程高いわけではなく、実生活において屋上が有効に利用されていないのが現状であった。これは、建物の居室と陸屋根が直接的に連絡していないことだけでなく、ベランダと陸屋根とが一体感をもって使用されにくいことも原因の一つであると考えられる。すなわち、特許文献１の図１に示されているように、ベランダと陸屋根とは平面視において隣接しているものの、屋外階段は陸屋根の中央部付近と連絡しているため、陸屋根に登った人とベランダにいる人とが顔を合わせるには、陸屋根に登った人がベランダに望む側に移動しなければならない。このため、陸屋根に登った人とベランダにいる人とのコミュニケーションが取りづらく、２つの空間は一体感を欠いた状態になっている。   However, even though a conventional building with an outdoor staircase can be climbed on a flat roof, the usage frequency is not so high, and the rooftop is not effectively used in real life. This is considered to be due not only to the fact that the room of the building and the flat roof are not in direct contact but also that the veranda and the flat roof are difficult to use with a sense of unity. That is, as shown in FIG. 1 of Patent Document 1, although the veranda and the flat roof are adjacent to each other in plan view, the outdoor staircase is in contact with the vicinity of the central portion of the flat roof. In order for the people on the veranda to meet each other, the person who climbed the roof must move to the side he wants on the veranda. For this reason, communication between the person who climbed the roof and the person on the veranda is difficult, and the two spaces lack a sense of unity.

本発明は、このような問題点を解決することを課題とするものであり、実生活において屋上がより有効に利用されやすい屋外階段付き建物を提供することを目的とする。   This invention makes it a subject to solve such a problem, and it aims at providing the building with an outdoor staircase which a roof is easy to use more effectively in real life.

本発明は、最上階の屋根が陸屋根である複数階建ての建物において、前記最上階、又は該最上階の直下の階に、上方が開放された開放領域を有するベランダを備え、該ベランダは、キッチンセットを有する居室、又は該居室に隣接して互いに行き来可能な他の居室に隣接するとともに、該ベランダに隣接する該居室又は該ベランダに隣接する該他の居室との間を区画する外周壁に、人が通行可能な開口部を有するものであって、前記陸屋根は、平面視において前記開放領域に隣接する歩行領域を備え、前記歩行領域における前記開放領域に望む側に、該歩行領域と該開放領域とを連絡する屋外階段を備える屋外階段付き建物である。   The present invention, in a multi-storey building in which the roof of the top floor is a flat roof, includes a veranda having an open area open on the top floor or a floor immediately below the top floor, An outer peripheral wall adjacent to a living room having a kitchen set or another living room adjacent to the living room and capable of moving to and from the living room adjacent to the veranda or the other living room adjacent to the veranda In addition, the flat roof has a walking area adjacent to the open area in plan view, and the walking area is located on a side desired by the open area in the walking area. It is a building with an outdoor stair including an outdoor stair that communicates with the open area.

前記歩行領域は、前記屋外階段が接続する領域を除いた全周に柵を備えることが好ましい。   It is preferable that the walking area includes a fence all around the area except the area where the outdoor staircase is connected.

前記陸屋根は、前記歩行領域を除く領域に、太陽光利用装置を設置可能な敷設領域を備えることが好ましい。   It is preferable that the flat roof has a laying area in which a solar light utilizing device can be installed in an area excluding the walking area.

前記柵の位置、材質、及び形状の少なくとも一つは、太陽光による該柵の影が前記太陽光利用装置のエネルギー取得効率に影響を及ぼさないように設定されることが好ましい。   It is preferable that at least one of the position, material, and shape of the fence is set so that the shadow of the fence due to sunlight does not affect the energy acquisition efficiency of the sunlight utilization device.

前記外周壁から前記ベランダ側に突き出す突設部を有し、該突設部に前記歩行領域の少なくとも一部が形成されており、前記屋外階段は、該突設部における該歩行領域に接続されていることが好ましい。   A projecting portion projecting from the outer peripheral wall toward the veranda, wherein at least a part of the walking area is formed in the projecting section, and the outdoor staircase is connected to the walking area in the projecting portion. It is preferable.

本発明では、ベランダが、キッチンセットを有する居室や、この居室と行き来可能な他の居室と隣接している。すなわち、多くの居住者が長時間在室する部屋にベランダが隣接しているので、ベランダを使用する頻度が高くなる結果、陸屋根に登る機会も増えることになる。しかも、陸屋根の歩行領域とベランダの開放領域とを連絡する屋外階段は、歩行領域における開放領域を望む側に設けているので、陸屋根に登った後でもすぐにベランダの人と顔を合わせることができる。このため、ベランダと陸屋根との一体的な使用が可能になり、屋上をより有効に利用することができる。   In the present invention, the veranda is adjacent to a living room having a kitchen set and other living rooms that can go to and from this living room. That is, since the veranda is adjacent to a room where many residents stay for a long time, the frequency of using the veranda increases, and as a result, the opportunity to climb on the flat roof increases. Moreover, the outdoor staircase that connects the walking area of the flat roof and the open area of the veranda is provided on the side where the open area of the walking area is desired, so it is possible to meet people on the veranda immediately after climbing the flat roof. it can. For this reason, the veranda and the flat roof can be used integrally, and the rooftop can be used more effectively.

図５に示すように建物１の２階部分には、１階部分に連絡する階段（屋内階段）３が設けられている。屋内階段３は、居室４につながっている。居室４には、建物１の中央南側にあたる位置にキッチンセット５が設けられている。本実施形態の居室４は、テーブルセット６やソファー７等を配置可能な、リビングダイニングキッチンとして使用できるように設けられている。なお、居室４の東側には、浴室８、洗面室９、トイレ１０が設けられている。   As shown in FIG. 5, a staircase (indoor staircase) 3 that communicates with the first floor portion is provided on the second floor portion of the building 1. The indoor staircase 3 is connected to the living room 4. In the living room 4, a kitchen set 5 is provided at a position corresponding to the central south side of the building 1. The living room 4 of this embodiment is provided so that it can be used as a living-dining kitchen in which the table set 6 and the sofa 7 can be arranged. A bathroom 8, a washroom 9, and a toilet 10 are provided on the east side of the living room 4.

居室４の南西側には、居室４に隣接してベランダ１１が設けられている。本実施形態のベランダ１１は、図５に示すように平面視において矩形状である。居室４とベランダ１１とは外周壁１２で区画されている。外周壁１２には、人が通行可能な開口部１３が設けられていて、居室４とベランダ１１との間を人が行き来することができる。開口部１３としては、例えば掃き出し窓やドア等を挙げることができる。本実施形態では、北側の外周壁１２ａにスライド式の掃き出し窓１３ａが設けられていて、東側の外周壁１２ｂにアコーディオン式の掃き出し窓１３ｂが設けられている。なお、ベランダ１１の南側、及び西側は、建物の外部壁１４で区画されている。   A veranda 11 is provided adjacent to the living room 4 on the southwest side of the living room 4. The veranda 11 of the present embodiment has a rectangular shape in plan view as shown in FIG. The living room 4 and the veranda 11 are partitioned by an outer peripheral wall 12. An opening 13 through which a person can pass is provided in the outer peripheral wall 12, and a person can go back and forth between the living room 4 and the veranda 11. Examples of the opening 13 include a sweep window and a door. In the present embodiment, a sliding sweep-out window 13a is provided on the outer peripheral wall 12a on the north side, and an accordion sweep-out window 13b is provided on the outer peripheral wall 12b on the east side. Note that the south side and the west side of the veranda 11 are partitioned by an external wall 14 of the building.

図１に示すように建物１の屋根は、水平方向に平坦な陸屋根１５として設けられている。陸屋根１５は、南西側が矩形状に切り欠かれるように設けられていて、ベランダ１１の中央部に、上方が開放された開放領域１１ａを形成している。本実施形態の陸屋根１５は、外周壁１２から庇のように延出する突設部１６を備えている。なお、突設部１６は陸屋根１５とは別異に設けたキャンティ屋根部や、ロッジア上部屋根として設けてもよい。本実施形態の突設部１６は、掃き出し窓１３ａの上方を覆う北側の突設部１６ａと、掃き出し窓１３ｂの上方を覆う東側の突設部１６ｂで構成されている（図５参照）。また、前述の外部壁１４は、図２、図３に示すようにその上端が、陸屋根１５と同じ高さに位置している。   As shown in FIG. 1, the roof of the building 1 is provided as a flat roof 15 that is flat in the horizontal direction. The flat roof 15 is provided so that the southwest side is cut out in a rectangular shape, and an open area 11 a having an open top is formed in the central portion of the veranda 11. The flat roof 15 of the present embodiment includes a protruding portion 16 that extends like a ridge from the outer peripheral wall 12. The projecting portion 16 may be provided as a Chianti roof portion provided separately from the land roof 15 or as an upper roof of the loggia. The projecting portion 16 of the present embodiment is configured by a north projecting portion 16a covering the upper side of the sweep window 13a and an east side projecting portion 16b covering the upper side of the sweep window 13b (see FIG. 5). Further, as shown in FIGS. 2 and 3, the outer wall 14 is located at the same height as the flat roof 15.

陸屋根１５には、人が活動することができる歩行領域１５ａが設けられている。図１に示すように歩行領域１５ａは、平面視において開放領域１１ａに隣接するように設けられている。本実施形態では、北側の突設部１６ａに重なるように歩行領域１５ａを設けている。   The flat roof 15 is provided with a walking area 15a where a person can act. As shown in FIG. 1, the walking area 15a is provided adjacent to the open area 11a in plan view. In the present embodiment, the walking region 15a is provided so as to overlap with the protruding portion 16a on the north side.

また、図１に示すように歩行領域１５ａにおける開放領域１１ａに望む側には、歩行領域１５ａと開放領域１１ａとを連絡する屋外階段１７が設けられている。本実施形態の屋外階段１７は、西側の桁面が西側の外部壁１４に沿うように直線状に設けられている。なお、本実施形態においては、歩行領域１５ａが北側の突設部１６ａに重なるように設けられているため、図５に示すように屋外階段１７は、掃き出し窓１３ａに対して南側に間隔をあけて設けられることになる。これにより、掃き出し窓１３ａを設置する位置の自由度が高まる他、掃き出し窓１３ａから出入りする際の圧迫感を抑制することができ、また屋外階段１７が掃き出し窓１３ａに及ぼす影の影響を抑えることができる。また屋外階段１７は、図５に示すように北側の突設部１６ａに対し、平面視において直交するように設けられている。このように設けることで、屋外階段１７と北側の突設部１６ａとの左右方向で絡む長さが短くなるため、上述した掃き出し窓１３ａを設置する位置の自由度が高まる効果や、掃き出し窓１３ａから出入りする際の圧迫感を抑制することができる効果、屋外階段１７が掃き出し窓１３ａに及ぼす影の影響を抑える効果を、より高めることができる。   Moreover, as shown in FIG. 1, the outdoor staircase 17 which connects the walking area | region 15a and the open area | region 11a is provided in the side desired in the open area | region 11a in the walking area | region 15a. The outdoor staircase 17 of the present embodiment is provided in a straight line so that the western girder face is along the western outer wall 14. In the present embodiment, since the walking area 15a is provided so as to overlap the protruding portion 16a on the north side, the outdoor staircase 17 is spaced southward with respect to the sweep window 13a as shown in FIG. Will be provided. As a result, the degree of freedom of the position where the sweep window 13a is installed is increased, the feeling of pressure when entering and exiting the sweep window 13a can be suppressed, and the influence of the shadow of the outdoor staircase 17 on the sweep window 13a can be suppressed. Can do. Moreover, the outdoor staircase 17 is provided so as to be orthogonal to the projecting portion 16a on the north side in a plan view as shown in FIG. By providing in this way, the length of the outdoor staircase 17 and the protruding portion 16a on the north side that is tangled in the left-right direction is shortened, so the effect of increasing the degree of freedom in the position of installing the sweep window 13a described above, and the sweep window 13a The effect which can suppress the feeling of pressure at the time of entering / exiting from, and the effect which suppresses the influence of the shadow which the outdoor staircase 17 has on the sweep window 13a can be heightened more.

歩行領域１５ａには、屋外階段１７が接続する領域を除いた全周に、柵１８が設けられている。本実施形態の柵１８は、図２、図３に示すように、上下方向に対をなす横桟１８ａの間に複数の縦桟１８ｂを設けて構成している。   In the walking area 15a, a fence 18 is provided all around the area excluding the area where the outdoor staircase 17 is connected. As shown in FIGS. 2 and 3, the fence 18 according to the present embodiment is configured by providing a plurality of vertical bars 18 b between horizontal bars 18 a that are paired in the vertical direction.

また、図１に示すように陸屋根１５における歩行領域１５ａを除く領域には、太陽光利用装置１９を設置可能な敷設領域１５ｂが設けられている。太陽光利用装置１９としては、例えば太陽電池パネルや太陽熱温水器の集熱器、蓄熱暖房設備の集熱器等が挙げられる。本実施形態の敷設領域１５ｂには、複数の太陽電池パネル１９ａと、太陽熱温水器の集熱器１９ｂが設けられている。   In addition, as shown in FIG. 1, a laying region 15 b in which the solar light utilizing device 19 can be installed is provided in a region other than the walking region 15 a on the flat roof 15. Examples of the solar light utilization device 19 include a solar battery panel, a solar water heater collector, a heat storage heater heat collector, and the like. In the laying region 15b of this embodiment, a plurality of solar cell panels 19a and a solar water heater 19b are provided.

そして本実施形態では、太陽光利用装置１９に対して柵１８を北西側に設けていることから、太陽光による柵１８の影が太陽光利用装置１９にかかる時間が短くなり、またその範囲も小さくなる。これによって、柵１８の影が太陽光利用装置１９のエネルギー取得効率に大きく影響しないようにしている。柵１８に対して太陽光利用装置１９を上方に設ける場合も、太陽光利用装置１９に対して柵１８の影がかかりにくくなる。また柵１８は、横桟１８ａと縦桟１８ｂによって枠状に設けられているので、影の面積も小さくなる。これにより、太陽光利用装置１９におけるエネルギー取得効率への影響がより小さくなる。なお、透明或いは半透明の材質で柵１８を形成することによっても、エネルギー取得効率への影響を小さくすることができる。   And in this embodiment, since the fence 18 is provided in the northwest side with respect to the sunlight utilization apparatus 19, the time which the shadow of the fence 18 by sunlight takes on the sunlight utilization apparatus 19 becomes short, and the range is also Get smaller. This prevents the shadow of the fence 18 from greatly affecting the energy acquisition efficiency of the solar light utilization device 19. Even when the solar light utilization device 19 is provided above the fence 18, the shadow of the fence 18 is less likely to be applied to the solar light utilization device 19. Moreover, since the fence 18 is provided in a frame shape by the horizontal rail 18a and the vertical rail 18b, the shadow area is also reduced. Thereby, the influence on the energy acquisition efficiency in the sunlight utilization apparatus 19 becomes smaller. In addition, the influence on energy acquisition efficiency can be made small also by forming the fence 18 with a transparent or translucent material.

このように構成される建物１にあっては、キッチンセット５を設けた居室４には多くの居住者が長時間在室することになる。これにより、居室４に隣接するベランダ１１を使用する頻度も高くなるため、屋外階段１７を使用して歩行領域１５ａに登る機会も増えることになる。また屋外階段１７は、掃き出し窓１３ｂの正面に位置するように設けられているため、居室４からでも視認しやすいことから屋外階段１７を利用するきっかけが生まれる。また屋外階段１７は、歩行領域１５ａにおける開放領域を望む側に設けていて、歩行領域１５ａに登った後でもすぐにベランダ１１の人と顔を合わせられるため、ベランダ１１と歩行領域１５ａとを一体的に利用することができる。これらの効果によって、歩行領域１５ａを使用する場面をより増やすことができる。   In the building 1 configured as described above, many residents are present in the living room 4 provided with the kitchen set 5 for a long time. Thereby, since the frequency which uses the veranda 11 adjacent to the living room 4 also becomes high, the opportunity to climb to the walking area 15a using the outdoor staircase 17 will also increase. Moreover, since the outdoor staircase 17 is provided so as to be positioned in front of the sweep-out window 13b, the outdoor staircase 17 is easily visible even from the living room 4, so that an opportunity to use the outdoor staircase 17 is created. The outdoor staircase 17 is provided on the side where the open area of the walking area 15a is desired, and the person can be faced with the person on the veranda 11 immediately after climbing the walking area 15a. Can be used. By these effects, the scene which uses the walking area | region 15a can be increased more.

また屋外階段１７は、建物の外側に位置する西側の桁面が外部壁１４に沿って設けられており、昇降の際に地上が見えにくくなっている。このため、高所が苦手な人にとっても屋外階段１７を利用しやすくなる。なお、屋外階段１７の西側の桁面は、外部壁１４との間で二重構造になる壁であってもよく、また、北側の突設部１６ａに対して入隅形状となる壁であってもよい。   In addition, the outdoor staircase 17 is provided with a western girder surface located outside the building along the external wall 14 so that it is difficult to see the ground when moving up and down. For this reason, it becomes easy to use the outdoor staircase 17 even for people who are not good at high places. The west girder surface of the outdoor staircase 17 may be a wall having a double structure with the external wall 14, or a wall having a corner shape with respect to the protruding portion 16a on the north side. May be.

また陸屋根１５に、歩行領域１５ａと敷設領域１５ｂを併設することによって、建物１の屋上が多目的に利用できることから、建物１の価値を高めることができる。しかも、歩行領域１５ａに登ることができるため、太陽光利用装置１９の維持管理や修理が容易に行えるようになる。ここで、歩行領域１５ａに給水装置を設けておけば、太陽光利用装置１９の受光面を洗浄することができるため、エネルギー取得効率を一層高めることができる。なお、屋上の利用効率を考慮すると、歩行領域１５ａよりも敷設領域１５ｂを広くすることが好ましい。また、使い勝手を考慮すると、歩行領域１５ａの面積は概ね３ｍ2以上１３ｍ2以下とすることが好ましい。 Moreover, since the roof area of the building 1 can be used for multiple purposes by providing the walking area 15a and the laying area 15b on the flat roof 15, the value of the building 1 can be increased. And since it can climb to the walk area | region 15a, the maintenance management and repair of the solar energy utilization apparatus 19 can be performed now easily. Here, if a water supply device is provided in the walking area 15a, the light receiving surface of the solar light utilization device 19 can be washed, and therefore energy acquisition efficiency can be further increased. In consideration of the rooftop utilization efficiency, it is preferable to make the laying region 15b wider than the walking region 15a. In consideration of usability, it is preferable that the area of the walking region 15a is approximately 3 m 2 or more and 13 m 2 or less.

次に、本発明の第二実施形態について、図６〜図１０を参照しつつ説明する。なお、第一実施形態と共通する機能を有する部位については、同一の符号を付して詳細な説明は省略する。   Next, a second embodiment of the present invention will be described with reference to FIGS. In addition, about the site | part which has a function which is common in 1st embodiment, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

本実施形態の建物２１は、先に説明したベランダ１１に対して、図６、図９に示すように西側に幅を広げたベランダ２２を備えている。ベランダ２２も、ベランダ１１と同様に、上方が開放された開放領域２２ａを備えている。また先の実施形態では、ベランダ１１の南側、及び西側は、背の高い建物の外部壁１４で区画していたが、ベランダ２２は、背の低い手摺り壁２３で区画している。更に太陽光利用装置１９は、複数の太陽電池パネル１９ａのみとし、先に述べた実施形態よりも柵１８から離隔するように設けている。   The building 21 of this embodiment is provided with a veranda 22 whose width is widened to the west as shown in FIGS. 6 and 9 with respect to the veranda 11 described above. As with the veranda 11, the veranda 22 includes an open area 22a that is open upward. In the previous embodiment, the south side and the west side of the veranda 11 are partitioned by the external wall 14 of the tall building, but the veranda 22 is partitioned by the short handrail wall 23. Furthermore, the solar light utilization device 19 includes only a plurality of solar battery panels 19a, and is provided so as to be separated from the fence 18 as compared with the embodiment described above.

また建物２１は、先に説明した直線状の屋外階段１７に替えて、螺旋状の屋外階段２４を備えている。螺旋状の屋外階段２４も、掃き出し窓１３ａに対して南側に間隔をあけて設けられ、また北側の突設部１６ａに対し、平面視において直交するように接続されている。これによって本実施形態でも、先の実施形態で説明したような、掃き出し窓１３ａを設置する位置の自由度が高まる効果等を得ることができる。また屋外階段２４は、西側の手摺り壁２３に対してベランダ２２の中央寄りに設けられており、昇降の際に地上が見えにくくなっている。よって、先に述べた屋外階段１７と同様に、高所が苦手な人にとっても利用しやすくなる。   The building 21 includes a spiral outdoor staircase 24 instead of the linear outdoor staircase 17 described above. The spiral outdoor staircase 24 is also provided with a space on the south side with respect to the sweep window 13a, and is connected to the north projecting portion 16a so as to be orthogonal in a plan view. Thereby, also in this embodiment, the effect of increasing the degree of freedom of the position where the sweep window 13a is installed as described in the previous embodiment can be obtained. The outdoor staircase 24 is provided near the center of the veranda 22 with respect to the handrail wall 23 on the west side, so that the ground is difficult to see when ascending and descending. Therefore, like the outdoor staircase 17 described above, it is easy to use even for people who are not good at high places.

建物２１においても、ベランダ２２が居室４に隣接しており、屋外階段２４が歩行領域１５ａにおける開放領域を望む側に設けられていることから、歩行領域１５ａが利用しやすくなる。   Also in the building 21, since the veranda 22 is adjacent to the living room 4 and the outdoor staircase 24 is provided on the side where the open area of the walking area 15a is desired, the walking area 15a can be easily used.
