Description

本発明は、高層建築物における竪穴区画構造に関する。さらに詳細には、本発明は、例えば高層建築物におけるエレベータシャフトの構造に関するものである。   The present invention relates to a pothole partition structure in a high-rise building. More specifically, the present invention relates to the structure of an elevator shaft, for example, in a high-rise building.

高層建築物における竪穴区画（エレベータシャフト、階段室、吹抜け空間、排煙シャフト、パイプスペース、ダクトスペースなど）では、冬期の屋内外温度差に起因して煙突効果を生じる。煙突効果は、ドラフト（すきま風）、音鳴り、空調負荷の増加など、様々な不具合の原因になる。   In a high-rise building, a stack structure (elevator shaft, staircase, atrium space, smoke exhaust shaft, pipe space, duct space, etc.) has a chimney effect due to a difference in indoor and outdoor temperatures in winter. The chimney effect causes various problems such as drafts, noises, and increased air conditioning load.

煙突効果により生じる差圧は、各部の扉に開閉障害をもたらすことがある。特に、高層建築物における低層部および高層部では、煙突効果に起因する差圧によりエレベータの扉の開閉が困難になることがある。煙突効果に関連する問題は冬期の一時期にのみ顕在化することが多いため、技術的に対策が難しく、大きな予算がかかる対策は困難である。   The differential pressure generated by the chimney effect may cause an open / close failure to the door of each part. In particular, in a low-rise building and a high-rise building in a high-rise building, it may be difficult to open and close the elevator door due to the differential pressure resulting from the chimney effect. Problems related to the chimney effect often manifest only during the winter season, so technical measures are difficult and measures that require a large budget are difficult.

本発明は、前述の課題に鑑みてなされたものであり、例えば高層建築物におけるエレベータシャフトにおいて煙突効果に起因する扉の開閉障害を回避することのできる竪穴区画構造を提供することを目的とする。   The present invention has been made in view of the above-described problems. For example, it is an object of the present invention to provide a pit-hole structure that can avoid a door opening / closing failure caused by a chimney effect in an elevator shaft in a high-rise building. .

前記課題を解決するために、本発明では、高層建築物において対象フロアの空間に面した扉を有する竪穴区画の構造であって、
前記対象フロアの直下の高さ位置に設けられて、前記竪穴区画の内部と前記高層建築物の外部とを選択的に連通させる開閉機構と、
前記扉の開放の直前に前記開閉機構を開け且つ前記扉の閉止の直後に前記開閉機構を閉じる駆動制御系とを備えていることを特徴とする竪穴区画構造を提供する。 In order to solve the above-mentioned problem, in the present invention, in a high-rise building, the structure of a pothole section having a door facing the space of the target floor,
An opening / closing mechanism that is provided at a height position directly below the target floor and selectively communicates the inside of the pothole section and the outside of the high-rise building;
There is provided a pothole partitioning structure comprising: a drive control system that opens the opening / closing mechanism immediately before opening the door and closes the opening / closing mechanism immediately after closing the door.

本発明の一形態では、例えば高層建築物におけるエレベータシャフトにおいて、対象フロアの直下の高さ位置にエレベータシャフトと高層建築物の外部とを選択的に連通させる開閉機構を設けているので、エレベータ扉の開放の直前に開閉機構を開け、エレベータ扉の閉止の直後に開閉機構を閉じることにより、煙突効果に起因する扉の開閉障害を回避することができる。   In one aspect of the present invention, for example, in an elevator shaft in a high-rise building, an opening / closing mechanism that selectively communicates the elevator shaft and the outside of the high-rise building is provided at a height position directly below the target floor. By opening the opening / closing mechanism immediately before opening the door and closing the opening / closing mechanism immediately after closing the elevator door, it is possible to avoid the door opening / closing failure due to the chimney effect.

本発明の実施形態を、添付図面に基づいて説明する。図１は、本発明の実施形態にかかる竪穴区画構造の構成を概略的に示す図である。本実施形態では、一例として、高層建築物におけるエレベータシャフトの構造に対して、本発明の竪穴区画構造を適用している。なお、図１では、紙面に限りがあるため、１０階建ての建築物を示しているが、本実施形態では数十階建ての高層建築物においてエレベータ１０のカゴ１０ａが最上階の対象フロア２１と地上フロア２２とを往復するケースを想定している。   Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram schematically showing a configuration of a pit hole structure according to an embodiment of the present invention. In the present embodiment, as an example, the pothole partition structure of the present invention is applied to the structure of an elevator shaft in a high-rise building. In FIG. 1, a 10-story building is shown because of limited space, but in the present embodiment, the cage 10 a of the elevator 10 is the target floor 21 on the top floor in a high-rise building with several tens of floors. And a ground floor 22 are assumed.

図１を参照すると、本実施形態のエレベータシャフト１１の構造では、対象フロア２１の直下の高さ位置に、エレベータシャフト１１の内部と高層建築物の外部３１とを選択的に連通させる開閉機構１２が設けられている。開閉機構１２は、例えばエレベータ機械室２３に設けられた駆動制御系１３からの指令にしたがって開閉機構１２を開けたり閉じたりする。駆動制御系１３は、後述するように、同じくエレベータ機械室２３に設けられたエレベータ制御部３０からの信号に応じて作動する。   Referring to FIG. 1, in the structure of the elevator shaft 11 of the present embodiment, an opening / closing mechanism 12 that selectively communicates the interior of the elevator shaft 11 and the exterior 31 of a high-rise building at a height position directly below the target floor 21. Is provided. The opening / closing mechanism 12 opens and closes the opening / closing mechanism 12 in accordance with a command from a drive control system 13 provided in the elevator machine room 23, for example. As will be described later, the drive control system 13 operates according to a signal from an elevator control unit 30 that is also provided in the elevator machine room 23.

図１では、エレベータシャフト１１の内部と高層建築物の外部３１とが１つの外壁３２により隔てられている例を示している。しかしながら、一般に、エレベータシャフト１１の内部と高層建築物の外部３１とが間隔を隔てている構成も考えられる。そのような構成の場合には、開閉機構１２と高層建築物の外部３１とを結ぶダクトを付加すれば良い。   FIG. 1 shows an example in which the inside of the elevator shaft 11 and the outside 31 of the high-rise building are separated by one outer wall 32. However, generally, a configuration is also conceivable in which the interior of the elevator shaft 11 and the exterior 31 of the high-rise building are spaced apart. In such a configuration, a duct connecting the opening / closing mechanism 12 and the outside 31 of the high-rise building may be added.

以下、本実施形態にかかるエレベータシャフト構造の作用の理解を容易にするために、図２〜図５を参照して従来の構造における煙突効果による上昇気流の発生および従来の煙突効果対策について説明する。従来の構造では、屋内外温度差に起因して、図２において矢印で示すような空気の流れが発生する。すなわち、エレベータシャフト５１の内部では煙突効果による上昇気流が発生する。   Hereinafter, in order to facilitate the understanding of the operation of the elevator shaft structure according to the present embodiment, the generation of ascending current due to the chimney effect and the conventional chimney effect countermeasures in the conventional structure will be described with reference to FIGS. . In the conventional structure, an air flow as indicated by arrows in FIG. That is, an updraft due to the chimney effect is generated inside the elevator shaft 51.

その結果、図２において破線状の楕円６１，６２で示すように、低層部の各フロアおよび高層部の各フロアでは、ドラフト圧力によるエレベータ扉の開閉障害が生じる。また、図２において破線状の楕円６３で示すように、地上フロアのエントランスでは、ドラフト気流による温熱環境の問題が生じる。   As a result, as shown by broken-line ellipses 61 and 62 in FIG. 2, an elevator door opening / closing failure due to the draft pressure occurs on each floor of the lower layer and each floor of the higher layer. In addition, as indicated by the dashed ellipse 63 in FIG. 2, there is a problem of the thermal environment due to the draft airflow at the entrance of the ground floor.

従来技術では、煙突効果に起因する扉の開閉障害などの対策として、例えば図３に示すように、高層部５２の各フロアにおける外壁５３の隙間をすべて塞ぐことにより建物外壁の気密性を向上させて煙突効果を低下させる手法が採用されている。また、例えば図４に示すように、エレベータシャフト５１の内部空間を下層空間５１ａと上層空間５１ｂとに隔絶分離することにより煙突効果を低下させる手法が採用されている。   In the prior art, as a countermeasure against a door opening / closing failure caused by the chimney effect, for example, as shown in FIG. 3, the airtightness of the outer wall of the building is improved by closing all the gaps of the outer wall 53 on each floor of the high-rise part 52. A technique to reduce the chimney effect is adopted. For example, as shown in FIG. 4, a method is adopted in which the chimney effect is reduced by separating and separating the internal space of the elevator shaft 51 into a lower layer space 51a and an upper layer space 51b.

また、図示を省略するが、エレベータ機械室の気密性向上や陽圧化、エレベータシャフト内の空気の冷却により煙突効果を低下させる手法が採用されている。さらに、例えば図５に示すように、エレベータシャフト５１の下部に外気５４を強制流入させてエレベータシャフト５１の内部を加圧することにより煙突効果を低下させる手法が採用されている。   Although illustration is omitted, a method of reducing the chimney effect by improving the air tightness of the elevator machine room, positive pressure, and cooling the air in the elevator shaft is adopted. Further, for example, as shown in FIG. 5, a method is adopted in which the chimney effect is reduced by forcing the outside air 54 into the lower portion of the elevator shaft 51 to pressurize the interior of the elevator shaft 51.

また、図示を省略するが、下層階エントランス等の気密化（風除室や回転扉の採用）、各階のエレベータから外壁に至る経路への扉の追加（各扉への差圧の分散）により煙突効果を低下させる手法が採用されている。ただし、建物の用途・デザインによる制約から、上述の手法を採用することができない場合がある。また、エレベータ扉に許容される差圧について、上述の手法を組み合わせても達成できないような厳しい条件が要求される場合がある。   Although not shown, due to airtightness at the lower floor entrances (adoption of windbreak rooms and revolving doors), addition of doors to the route from the elevators to the outer walls of each floor (dispersion of differential pressure to each door) A technique to reduce the chimney effect is adopted. However, there are cases where the above-mentioned method cannot be adopted due to restrictions on the use and design of the building. In addition, there may be demands for strict conditions that cannot be achieved by combining the above-described methods for the differential pressure allowed for the elevator door.

煙突効果の根本的な要因は、屋内外の温度差である。冬期には外気温度が０°Ｃ前後になるが、屋内は１８°Ｃ程度に空調される。このため、屋内の空気は、浮力を生じて外壁を介して外へ出ようとする。高層建築物では、各階においてこのような煙突効果による浮力を生じ、この浮力が竪穴区画に集中して大きな圧力差を生じる。煙突効果に起因する圧力差は、屋内外温度差が存在する限り定常的に生じる。   The fundamental factor of the chimney effect is the temperature difference between indoor and outdoor. In winter, the outside air temperature is around 0 ° C, but the room is air-conditioned to about 18 ° C. For this reason, indoor air produces buoyancy and tends to go outside through the outer wall. In a high-rise building, buoyancy due to such a chimney effect is produced on each floor, and this buoyancy is concentrated in the pit compartment, creating a large pressure difference. The pressure difference due to the chimney effect is steadily generated as long as there is an indoor / outdoor temperature difference.

以下、図６〜図９を参照して、本実施形態にかかるエレベータ１０の構造の作用を説明する。図６は、エレベータ１０のカゴ１０ａが地上フロア２２にあり、対象フロア２１を含むすべてのフロアにおいてエレベータ扉が閉じている様子を示している。図６に示す状態では、エレベータ機械室２３に設けられた駆動制御系１３からの指令により、開閉機構１２は閉じている。   Hereinafter, the operation of the structure of the elevator 10 according to the present embodiment will be described with reference to FIGS. FIG. 6 shows a state where the cage 10 a of the elevator 10 is on the ground floor 22 and the elevator doors are closed on all floors including the target floor 21. In the state shown in FIG. 6, the opening / closing mechanism 12 is closed by a command from the drive control system 13 provided in the elevator machine room 23.

その結果、図６中矢印で示すような空気の流れが発生し、エレベータシャフト１１の内部では煙突効果による上昇気流が発生する。そして、対象フロア２１におけるエレベータ１０の扉には、図６において破線状の楕円３３で示すように比較的大きな差圧が作用する。ただし、図６に示す状態では、対象フロア２１におけるエレベータ１０の扉は開く必要がないので問題はない。   As a result, an air flow as indicated by an arrow in FIG. 6 is generated, and an updraft due to the chimney effect is generated inside the elevator shaft 11. Then, a relatively large differential pressure acts on the door of the elevator 10 on the target floor 21 as indicated by the dashed ellipse 33 in FIG. However, in the state shown in FIG. 6, there is no problem because the door of the elevator 10 on the target floor 21 does not need to be opened.

図７は、エレベータ１０のカゴ１０ａが地上フロア２２から対象フロア２１に近づいて所定の高さ位置に達したときに、開閉機構１２が閉じた状態から開いた状態に変化した様子を示している。すなわち、本実施形態において、エレベータ制御部３０は、エレベータ１０のカゴ１０ａが対象フロア２１から下方へ所定距離だけ離れた高さ位置を対象フロア２１へ向かって通過したときに、通過信号を駆動制御系１３に出力する。駆動制御系１３は、エレベータ制御部３０から供給された通過信号を受けて開閉機構１２を開ける。   FIG. 7 shows a state in which the opening / closing mechanism 12 changes from a closed state to an open state when the car 10a of the elevator 10 approaches the target floor 21 from the ground floor 22 and reaches a predetermined height position. . In other words, in the present embodiment, the elevator control unit 30 drives and controls the passing signal when the car 10a of the elevator 10 passes through the height position away from the target floor 21 by a predetermined distance toward the target floor 21. Output to system 13. The drive control system 13 opens the opening / closing mechanism 12 in response to the passage signal supplied from the elevator control unit 30.

その結果、煙突効果により発生した上昇空気は対象フロア２１の直下の高さ位置に設けられた開閉機構１２を介して外部へ流出し、対象フロア２１におけるエレベータ１０の扉に作用する差圧は、図９に示すように急激に減少し始める。図９は、開閉機構の開閉と対象フロアにおけるエレベータ扉に作用する差圧との関係について得られたシミュレーション結果を定性的に示す図である。図９において、縦軸はエレベータ扉に作用する差圧Ｐを示し、横軸は開閉機構１２の開閉に伴って経過する時間Ｔを示している。   As a result, the rising air generated by the chimney effect flows out to the outside through the opening / closing mechanism 12 provided at a height position directly below the target floor 21, and the differential pressure acting on the door of the elevator 10 on the target floor 21 is As shown in FIG. 9, it starts to decrease rapidly. FIG. 9 is a diagram qualitatively showing simulation results obtained regarding the relationship between opening / closing of the opening / closing mechanism and differential pressure acting on the elevator door on the target floor. In FIG. 9, the vertical axis indicates the differential pressure P acting on the elevator door, and the horizontal axis indicates the time T that elapses with the opening / closing of the opening / closing mechanism 12.

エレベータ制御部３０は、通過信号を駆動制御系１３に出力した直後にエレベータ扉の開放信号を出力し、開放信号の出力直後にエレベータ１０の扉が開く。図８は、開閉機構１２が開いた直後に対象フロア２１におけるエレベータ１０の扉が開いた様子を示している。換言すると、本実施形態において、駆動制御系１３は、エレベータ１０の扉の開放の直前に開閉機構１２を開ける。   The elevator control unit 30 outputs an elevator door opening signal immediately after outputting the passage signal to the drive control system 13, and the elevator 10 door opens immediately after the opening signal is output. FIG. 8 shows a state in which the door of the elevator 10 on the target floor 21 is opened immediately after the opening / closing mechanism 12 is opened. In other words, in this embodiment, the drive control system 13 opens the opening / closing mechanism 12 immediately before the door of the elevator 10 is opened.

図９を参照すると、時間Ｔ１のタイミングで開閉機構１２が開いてから、対象フロア２１におけるエレベータ１０の扉に作用する差圧はＰ１から急激に減少し始め、時間Ｔ２のタイミングでエレベータ扉が開いたときには扉に作用する差圧Ｐ２が十分小さくなることがわかる。このように、エレベータ１０の扉の開放の直前における開閉機構１２の開放により、エレベータ扉に作用する差圧は著しく低減される。その結果、煙突効果に起因する扉の開閉障害を回避することができる。   Referring to FIG. 9, after the opening / closing mechanism 12 is opened at the timing of time T1, the differential pressure acting on the door of the elevator 10 on the target floor 21 starts to rapidly decrease from P1, and the elevator door is opened at the timing of time T2. It can be seen that the differential pressure P2 acting on the door is sufficiently small. In this way, the differential pressure acting on the elevator door is significantly reduced by opening the opening / closing mechanism 12 immediately before the door of the elevator 10 is opened. As a result, it is possible to avoid a door opening / closing failure due to the chimney effect.

エレベータ１０に対する乗降が終了すると、エレベータ制御部３０はエレベータ扉の閉止信号を出力し、この閉止信号の出力直後に時間Ｔ３のタイミングでエレベータ扉を閉じる。駆動制御系１３は、エレベータ制御部３０から供給されたエレベータ扉の閉止信号を受けて、エレベータ扉が閉じた直後に時間Ｔ４のタイミングで開閉機構１２を閉じる。すなわち、本実施形態において、駆動制御系１３は、エレベータ１０の扉の閉止の直後に開閉機構１２を閉じる。時間Ｔ３のタイミングで開閉機構１２を閉じるときにエレベータ扉に作用する差圧Ｐ３は十分小さく、煙突効果に起因する扉の開閉障害を回避することができる。   When the elevator boarding / exiting is completed, the elevator control unit 30 outputs an elevator door closing signal, and immediately after the closing signal is output, the elevator door is closed at the timing of time T3. The drive control system 13 receives the elevator door closing signal supplied from the elevator controller 30, and closes the opening / closing mechanism 12 at time T4 immediately after the elevator door is closed. That is, in this embodiment, the drive control system 13 closes the opening / closing mechanism 12 immediately after the door of the elevator 10 is closed. The differential pressure P3 acting on the elevator door when the opening / closing mechanism 12 is closed at the timing of time T3 is sufficiently small, and the door opening / closing failure due to the chimney effect can be avoided.

図９において実線で示すように、エレベータ１０の扉の閉止直後に開閉機構１２を閉じることにより、エレベータ扉に作用する差圧はＰ３から元の差圧Ｐ１まで急激に戻り、これにより次のエレベータ扉の開放時に備えることができる。一方、図９において破線で示すように、エレベータ１０の扉の閉止後も開閉機構１２を開けたままに放置すると、いわゆる圧力逃がしの効果は次第に失われ、これにより次のエレベータ扉の開放時に圧力を逃がせなくなる。   As shown by a solid line in FIG. 9, by closing the opening / closing mechanism 12 immediately after the door of the elevator 10 is closed, the differential pressure acting on the elevator door suddenly returns from P3 to the original differential pressure P1, thereby the next elevator. Can be provided when the door is opened. On the other hand, as shown by a broken line in FIG. 9, if the opening / closing mechanism 12 is left open even after the door of the elevator 10 is closed, the so-called pressure relief effect is gradually lost, whereby the pressure is increased when the next elevator door is opened. Can not escape.

一般に、上層階のフロア全体が展望室、食堂、結婚式場などになっている高層建築物では、エレベータホールを設けてフロアとエレベータとを隔離するようなデザインが難しく、エレベータから外壁に至る経路への扉の追加（各扉への差圧の分散）により煙突効果を低下させる手法の採用が困難である。目的の高層階までのエレベータを有する場合、低層階からエレベータが上昇してくるタイミングに一定の間隔があり、またエレベータ扉を開閉させるタイミングを予測することができる。このような場合には、上述のように、圧力逃がしの開閉機構を設け、エレベータ扉を開ける直前にエレベータシャフト内部の圧力逃がしを行うことにより、煙突効果に起因する扉の開閉障害等を回避することができる。   In general, in high-rise buildings where the entire upper floor is an observation room, cafeteria, wedding hall, etc., it is difficult to design an elevator hall to separate the floor from the elevator, and the route from the elevator to the outer wall It is difficult to adopt a method of reducing the chimney effect by adding a door (dispersion of differential pressure to each door). When there is an elevator up to the target higher floor, there is a certain interval in the timing when the elevator ascends from the lower floor, and the timing for opening and closing the elevator door can be predicted. In such a case, as described above, a pressure relief opening / closing mechanism is provided, and pressure relief inside the elevator shaft is performed immediately before the elevator door is opened, thereby avoiding a door opening / closing failure caused by the chimney effect. be able to.

なお、上述の説明では、エレベータ１０のカゴ１０ａが対象フロア２１から下方へ所定距離だけ離れた高さ位置を対象フロア２１へ向かって通過したときにエレベータ制御部３０が出力する信号に応じて、駆動制御系１３が開閉機構１２を開けている。しかしながら、これに限定されることなく、エレベータ制御部３０が出力するエレベータ扉の開放信号に応じて開閉機構１２を開ける形態も可能である。例えば、エレベータのカゴが対象フロアに既にあり、呼びボタンが押された場合がこの形態に相当する。   In the above description, according to the signal output by the elevator control unit 30 when the car 10a of the elevator 10 passes the height position away from the target floor 21 by a predetermined distance toward the target floor 21, The drive control system 13 opens the opening / closing mechanism 12. However, the present invention is not limited to this, and a mode in which the opening / closing mechanism 12 is opened in accordance with an elevator door opening signal output from the elevator control unit 30 is also possible. For example, the case where the elevator car is already on the target floor and the call button is pressed corresponds to this form.

また、上述の説明では、各フロアに停止可能な通常のエレベータのエレベータシャフトに対して、本発明の竪穴区画構造を適用している。しかしながら、通常のエレベータに限定されることなく、例えば最上階のフロアと地上フロアとを往復するシャトルエレベータシャフト、階段室など、高層建築物において対象フロアの空間に面した扉を有する他の竪穴区画の構造に対しても同様に本発明を適用することができる。   Further, in the above description, the pit hole partition structure of the present invention is applied to an elevator shaft of a normal elevator that can be stopped on each floor. However, the present invention is not limited to a normal elevator, and other pit holes having a door facing the space of the target floor in a high-rise building such as a shuttle elevator shaft that reciprocates between the top floor and the ground floor, a staircase, etc. The present invention can be similarly applied to the structure.

高層建築物において対象フロアの空間に面した扉を有する通常のエレベータシャフトの構造に対して本発明を適用する場合、駆動制御系は、エレベータ制御部が出力するエレベータ扉の開放信号に応じて開閉機構を開け、エレベータ制御部が出力するエレベータ扉の閉止信号に応じて開閉機構を閉じる。   When the present invention is applied to the structure of a normal elevator shaft having a door facing the space of the target floor in a high-rise building, the drive control system opens and closes according to the elevator door opening signal output by the elevator controller. The mechanism is opened, and the opening / closing mechanism is closed in response to the elevator door closing signal output by the elevator controller.

また、高層建築物において対象フロアの空間に面した扉を有する階段室の構造に対して本発明を適用する場合、駆動制御系は、階段室の扉の開放操作に対応する開放信号（例えば階段室の扉のノブの回転に応じて発生する開放信号）に応じて開閉機構を開け、階段室の扉の閉止に対応する閉止信号に応じて開閉機構を閉じる。   In addition, when the present invention is applied to the structure of a staircase having a door facing the space of the target floor in a high-rise building, the drive control system has an open signal (for example, a staircase) corresponding to the opening operation of the staircase The opening / closing mechanism is opened in response to the rotation of the knob of the room door, and the opening / closing mechanism is closed in response to the closing signal corresponding to the closing of the staircase door.

以上のように、本発明による煙突効果対策は、従来の手法で対策し切れない現象が生じた場合にも有効であり、煙突効果に起因する現象のうち、直接の被害につながりかねないエレベータ扉の開閉障害の問題（現象が激しい場合にはエレベータの運行を見合わせる場合もある）を回避することができる点で意義が大きい。   As described above, the chimney effect countermeasure according to the present invention is effective even when a phenomenon that cannot be completely counteracted by the conventional method occurs, and the elevator door that may lead to direct damage among the phenomenon caused by the chimney effect. This is significant in that it can avoid the problem of opening / closing troubles (if the phenomenon is severe, the operation of the elevator may be delayed).
