Description

本発明は、複数棟の階段室型共同住宅を、片廊下型の共同住宅に改築するとともに同時に一体化することができる方法及びこの方法で改築された建築物に関する。   The present invention relates to a method capable of remodeling a plurality of staircase-type apartment houses into a one-way corridor-type apartment house and simultaneously integrating them, and a building rebuilt by this method.

隣接する住戸間に各住戸への出入口に接続する屋外階段を備えた構造の共同住宅は一般に階段室型共同住宅と呼ばれている。
このような階段室型共同住宅のうち、昭和３０年代から４０年代にかけて竣工された住棟は老朽化がすすんでいるため、早急な建て替え等が望まれているが、既存の全ての住棟を全て建て替えるのは現実的には容易なことではなく、膨大な量の建築廃材の発生や建て替えに伴う居住者の引越しの問題もある。
また、このような階段室型共同住宅は居住者に高齢者が多いことから、上層階に居住する高齢者にとっては階段での上り下りが大変であるという問題を抱えている。
更に、外部への経路が隣接する住戸と共通の階段室のみであるために、避難経路が限定されてしまい、火災や地震等の災害発生時において、避難が困難となる場合があるという問題もあった。
また、階段室型共同住宅は、通常、複数棟が並んで建てられているものであり、別棟に住む居住者同士が親しくなって頻繁にお互いの住居を行き来することも多くあるが、別棟の共同住宅の上層階に住む居住者同士の場合には、例えそれがすぐ隣りの棟であったとしても、相手の住居を訪問するのが大変であり、日常生活に不便を感じることがあった。 An apartment house with an outdoor staircase connected to the entrance to each unit between adjacent units is generally called a staircase type apartment house.
Of these staircase-type apartments, the residences completed in the 1950s and 1940s are aging, so immediate rebuilding is desired. In reality, it is not easy to rebuild all of them, and there is a problem of the generation of a huge amount of building waste and the moving of residents accompanying the rebuilding.
In addition, such a staircase-type apartment house has a problem that it is difficult for the elderly living on the upper floors to go up and down the stairs because there are many elderly people in the residents.
In addition, since the route to the outside is only the common staircase with the adjacent dwelling unit, the evacuation route is limited, and it may be difficult to evacuate in the event of a disaster such as a fire or earthquake. there were.
In addition, staircase-type apartments are usually built side by side, and there are many cases where residents living in separate buildings become close to each other and frequently move back and forth between each other. In the case of residents living on the upper floors of an apartment house, even if it is a neighboring building, it is difficult to visit the other's residence, and it may be inconvenient in daily life .

上記したような問題点に鑑みて、既存の階段室型共同住宅を片廊下型の共同住宅に改築してエレベータを設置する方法が提案されている（下記特許文献１参照）。   In view of the above problems, there has been proposed a method in which an existing staircase type apartment house is remodeled into a one-way corridor type apartment house and an elevator is installed (see Patent Document 1 below).

しかしながら、特許文献１の開示技術では、階段室部分を完全に解体撤去してしまうため、工事に時間がかかり、比較的長期間にわたって居住者の出入りが制限されてしまうという問題があった。
しかも、階段室の解体撤去作業は、部屋のごく近傍で行われることから室内に騒音が伝わりやすく、そのため居住者は長期間に亘って工事の騒音を我慢しなければならないという問題もあった。
また、別棟の住居に住む居住者の訪問の大変さはエレベータの設置により若干改善するものの、上層階に住む居住者同士が行き来する場合には、いったん上層階から１階まで下りてから上層階まで上がるのに時間がかかるため、やはり移動が大変であることには変わりなかった。
更に、ある建物が火災や地震によって大きな被害を受けることにより、その建物に設置されたエレベータや避難階段を使用して避難することが困難となる場合があり、このような場合、避難経路が絶たれてしまって生命の危険に晒される可能性があった。 However, in the disclosed technique of Patent Document 1, since the staircase portion is completely dismantled and removed, it takes time for the construction, and there is a problem that resident access is restricted for a relatively long period of time.
Moreover, since the dismantling / removal work of the staircase is performed in the very vicinity of the room, noise is easily transmitted to the room, so that there is a problem that the resident has to endure the construction noise for a long period of time.
In addition, although the difficulty of visiting residents living in a separate building is slightly improved by installing an elevator, if residents living on the upper floors go back and forth, they must go down from the upper floor to the first floor and then go to the upper floor. Since it took time to go up, it was still difficult to move.
In addition, if a building is severely damaged by a fire or earthquake, it may be difficult to evacuate using the elevators or evacuation stairs installed in the building. There was a possibility of being exposed to the danger of life.

一方、本願出願人は、既存の階段室型共同住宅を片廊下型の共同住宅に改築すると同時に上方へと増築することができる方法を提案している（下記特許文献２参照）。   On the other hand, the applicant of the present application has proposed a method in which an existing staircase-type apartment house can be remodeled into a one-way corridor-type apartment house and can be extended upward (see Patent Document 2 below).

この特許文献２の開示技術は、住みながらにして既存の中層階段室型共同住宅を高層の片廊下型の共同住宅へと変更することができるとともに、部屋の増床も可能であるという従来にない非常に画期的な技術であったが、上記したような階段室の解体撤去作業に関わる問題点については解消できるものではなかった。
また、上記したような、別棟の住居に住む居住者の行き来の大変さや、大規模な災害により避難経路が絶たれる可能性があるという問題についても解決できるものではなかった。 The technology disclosed in Patent Document 2 can be used to change an existing medium-rise staircase type apartment house to a high-rise one-way corridor type apartment while living, and to increase the floor area of the room. Although it was a very innovative technology, the problems related to the work of dismantling and removing the staircase as described above could not be solved.
In addition, the above-mentioned problems such as difficulty in coming and going of residents living in the residences in the annex and the possibility that the evacuation route may be interrupted due to a large-scale disaster cannot be solved.

更に、特許文献３には、階段室型共同住宅の折り返し階段の下半分を撤去し、その下部に新設階段を連結することによって、階段を直線化した改良階段とする、階段室型共同住宅のバリアフリー化改修方法が開示されており、この方法によれば、階段室の解体撤去作業に関わる問題点を解消することが可能である。
しかしながら、この特許文献３の開示技術によっても、やはり上記したような別棟への行き来の大変さや大規模災害時の避難経路の問題については解決できるものではなかった。 Furthermore, in Patent Document 3, the lower half of the folded staircase of the staircase-type apartment house is removed, and a new staircase is connected to the lower part of the staircase-type apartment house. A barrier-free refurbishment method is disclosed, and according to this method, it is possible to eliminate the problems associated with the work of dismantling and removing the staircase.
However, even the disclosed technique of Patent Document 3 cannot solve the above-described difficulty of going to another building and the problem of the evacuation route at the time of a large-scale disaster.

以上のように、特許文献１乃至３の開示技術は、いずれも１棟の階段室型共同住宅について増改築方法を提示しているに過ぎず、複数棟の建物の存在により生じる問題点を解決するための手段を何ら提示していないものであった。   As described above, all of the disclosed technologies of Patent Documents 1 to 3 only provide an extension and remodeling method for a single staircase type apartment house, and solve the problems caused by the existence of multiple buildings. It did not present any means for doing this.

本発明は、上記実情に鑑みてなされたものであって、階段室型共同住宅を片廊下型の共同住宅へと変更することができて、エレベータの設置や複数の避難経路の確保が可能となるとともに、施工中においても居住者が快適に日常生活を営むことができ、しかも別棟の建物への移動を容易として日常生活の便利さと共に災害時の避難経路の多様さも確保することが可能な、複数棟からなる階段室型共同住宅の改築方法及びこの方法で改築された建築物を提供せんとするものである。   The present invention has been made in view of the above circumstances, and the staircase type apartment house can be changed to a one-way corridor type apartment house, and it is possible to install an elevator and secure a plurality of evacuation routes. In addition, residents can operate their daily lives comfortably even during construction, and it is easy to move to a building in a separate building, ensuring the convenience of daily life as well as the diversity of evacuation routes during disasters.

図１２は、既存住宅が、桁行方向が略直線状となるように直列配置された複数棟の建物からなる建物群が複数（図示例では２群）あり、一方の建物群（Ａ）と他方の建物群（Ｂ）とが、桁行方向が略平行となるように並列配置されているものである場合である。
この場合、改築建物の外部廊下（１１Ａ）は、それぞれの建物群において略直線状の配置となっており、且つ一方の建物群（Ａ）の外部廊下と他方の建物群（Ｂ）の外部廊下とは略平行の配置となっている。 In FIG. 12, there are a plurality of building groups (two groups in the illustrated example) composed of a plurality of buildings in which existing houses are arranged in series so that the crossing direction is substantially linear, and one building group (A) and the other The building group (B) is arranged in parallel so that the column direction is substantially parallel.
In this case, the external corridor (11A) of the renovated building is arranged in a substantially straight line in each building group, and the external corridor of one building group (A) and the external corridor of the other building group (B). Is substantially parallel.

そこで、先ず、夫々の建物群において外部廊下（１１Ａ）の端部同士を連結用廊下（１１Ｂ）で連結することにより、夫々の建物群において新規廊下を全体として平面視にて直線状に形成する。
次いで、一方の建物群の新規廊下と他方の建物群の新規廊下とを、空中廊下（１１Ｃ）により連結する。このとき、空中廊下（１１Ｃ）は、必ず全ての改築建物の外部廊下（１１Ａ）に対して取り付けるようにする。 Therefore, first, the end portions of the external hallway (11A) in each building group are connected to each other by the connecting hallway (11B), so that the new hallway as a whole is linearly formed in plan view in each building group. .
Next, the new hallway of one building group and the new hallway of the other building group are connected by an aerial hallway (11C). At this time, the air corridor (11C) must be attached to the external corridor (11A) of all the renovated buildings.

外部廊下（１１Ａ）の連結部に設けられる連結用廊下（１１Ｂ）には、避難階段（１３）又はエレベータ（１５）が設けられる。
このとき、図示の如く、避難階段（１３）とエレベータ（１５）を廊下の長さ方向に沿って交互に配置すると、避難階段（１３）とエレベータ（１５）を選択的に利用することが容易となって避難時の安全性が高められるために好ましい。 An escape staircase (13) or an elevator (15) is provided in the connecting corridor (11B) provided at the connecting portion of the external corridor (11A).
At this time, as shown in the figure, if the evacuation stairs (13) and the elevator (15) are alternately arranged along the length direction of the hallway, it is easy to selectively use the evacuation stairs (13) and the elevator (15). This is preferable because safety during evacuation is improved.

図１２に示したような連結形態を採ることにより、各建物群の中において隣り合う改築建物への移動が容易となるのに加えて、異なる建物群にも空中廊下を渡って移動することができるため、既存住宅が多数棟からなる場合において、日常生活における利便性や避難時の安全性を大きく向上させることができる。   By adopting the connection form as shown in FIG. 12, in addition to facilitating movement to adjacent renovated buildings in each building group, it is also possible to move across aerial corridors to different building groups. Therefore, when the existing house is composed of many buildings, the convenience in daily life and the safety during evacuation can be greatly improved.
