Description

本発明は、既設建物の増築方法及びこの方法により増築された建物に関し、より詳しくは、複数の建物が渡り廊下により接続された構造を有する既設建物において、既設建物を使用しながら上方に増築することができるとともに、充分な建物強度を確保することができ、しかも空きスペースを有効利用することを可能とする増築方法及びこの方法により増築された建物に関する。   The present invention relates to an extension method of an existing building and a building extended by this method, and more specifically, in an existing building having a structure in which a plurality of buildings are connected by a crossing corridor, it is extended upward while using the existing building. Further, the present invention relates to an extension method that can secure sufficient building strength and that can effectively use an empty space, and a building extended by this method.

従来、例えば２階建ての建物を３階建てにするためには、柱や壁、梁等の強度の関係から、２階の上部に更に新規の３階部分を構築することはできず、先ず既設の２階建ての建物を全て撤去し、その跡地に３階建ての建物を構築する他はなかったが、このような従来の方法は、不経済であるばかりでなく、産業廃棄物の増加を引き起こし、また居住者は新規建物が完成するまで転居を強いられることとなっていた。   Conventionally, for example, in order to make a two-story building into a three-story building, a new three-story part cannot be built on the upper part of the second floor because of the strength of pillars, walls, beams, etc. There was no other way than removing all existing two-story buildings and building a three-story building on the site, but this conventional method is not only uneconomical, but also increases industrial waste. And the residents were forced to move until the new building was completed.

そこで、このような実情に鑑みて、本願発明者は、既設の建物を活用し、居住者が一時的にせよ転居することなく、そのまま鉛直方向上方に増築が可能な建築方法および建築物を提案している（特許文献１参照）。
この特許文献１に記載の発明は、既設の建物の周囲を囲うように新たな基礎を設け、新たな基礎の上部に鉄骨柱を立設して既設建物の上方に新規建物を構築するという斬新な発想に基づいたものであり、従来の増築方法に関わる問題点の多くを解決することができる優れた発明である。 Therefore, in view of such circumstances, the inventor of the present application proposes a construction method and a building that can be used for the extension in the vertical direction as it is without occupants moving temporarily, even if the occupants temporarily move. (See Patent Document 1).
The invention described in Patent Document 1 is a novel design in which a new foundation is provided so as to surround the existing building, and a new structure is constructed above the existing building by standing a steel column above the new foundation. This is an excellent invention that can solve many of the problems associated with conventional extension methods.

しかしながら、特許文献１に開示された増築方法は、戸建て住宅の増築方法に適用するには優れた方法であるが、例えば既設建物が平面的に大規模なものである場合、強度的な問題が生じる可能性があった。   However, the extension method disclosed in Patent Document 1 is an excellent method for applying to the extension method of a detached house. However, for example, when an existing building is large in plan, there is a problem of strength. Could have occurred.

すなわち、特許文献１に開示された増築方法は、既設建物の外側を囲うように立設された増築用の柱間に梁を架設し、この梁の上方に新規に上層階を構築する方法であるから、既設建物が平面的に大規模なものである場合には、既設建物の上方に架設される梁のスパンが長くなり、その結果、既設建物の上部に構築される上層階の重量に耐えるだけの充分な強度を確保することが困難となる場合があった。   In other words, the extension method disclosed in Patent Document 1 is a method in which a beam is installed between columns for extension that are erected so as to surround the outside of an existing building, and a new upper floor is built above the beam. Therefore, if the existing building is large in plan, the span of the beam constructed above the existing building becomes longer, resulting in the weight of the upper floor built on top of the existing building. In some cases, it is difficult to ensure sufficient strength to withstand.

例えば、既設の小中学校の校舎等には、複数の建物が渡り廊下によって接続されている構造の建物が比較的多い。
このような構造の建物は、建物自体の面積はそれほど広くなくても、渡り廊下によって建物同士の間が隔てられているために、特許文献１の開示技術をそのまま適用しようとすると、既設建物の上方に架設される梁のスパンが長くなり、充分な強度を確保することが困難であった。
更に、渡り廊下により隔てられた建物間には空間があるが、特許文献１の開示技術をそのまま適用した場合、この空間が増築された建物内部にそのまま取り込まれてしまうため、空間を有効利用することが困難であった。 For example, in existing elementary and junior high school buildings, there are relatively many buildings with a structure in which a plurality of buildings are connected by a corridor.
Even if the area of the building itself is not so large, the building having such a structure is separated from each other by a corridor. Therefore, if the technique disclosed in Patent Document 1 is applied as it is, it is located above the existing building. As a result, the span of the beam installed on the tube became long, and it was difficult to ensure sufficient strength.
Furthermore, there is a space between the buildings separated by the corridor, but when the technique disclosed in Patent Document 1 is applied as it is, this space will be taken into the expanded building as it is, so that the space should be used effectively. It was difficult.

一方、本願出願人は、上記した強度面の問題点に鑑みて、特許文献１の開示技術をコンビニエンスストア等の正面幅が広い店舗建築物に対して適用できるようにした技術を既に提案している（特許文献２参照）。   On the other hand, the applicant of the present application has already proposed a technique in which the disclosed technique of Patent Document 1 can be applied to a store building having a wide front width, such as a convenience store, in view of the above-described problems of strength. (See Patent Document 2).

すなわち、特許文献２には、梁を軸方向に補強材を内在したコンクリート梁から構成し、梁の間に掛け渡されるパネルを長さ方向に補強材を内在した複数枚のコンクリートパネルから構成する技術が開示されている。   That is, in Patent Document 2, the beam is composed of a concrete beam including a reinforcing material in the axial direction, and the panel spanned between the beams is composed of a plurality of concrete panels including the reinforcing material in the length direction. Technology is disclosed.

この特許文献２の開示技術によれば、上記した強度上の問題点を解決することが可能であるが、特別に強化された梁やパネルを用いるために、施工コストの面では好ましくなく、経済的な方法とはいえなかった。
しかも、この開示技術によっても、複数の建物が渡り廊下によって接続されている構造をもつ建物において、建物間の空間を有効利用することが困難であるという問題については、解決することはできなかった。 According to the technology disclosed in Patent Document 2, it is possible to solve the above-described problems in strength, but since a specially strengthened beam or panel is used, it is not preferable in terms of construction cost and economical. It was not an effective method.
Moreover, even with this disclosed technology, it has been impossible to solve the problem that it is difficult to effectively use the space between buildings in a building having a structure in which a plurality of buildings are connected by a passageway.

FIG. 1 to FIG. 4 are explanatory views showing a first embodiment of an extension method of an existing building according to the present invention in the order of steps, FIG. 1 shows a state before construction, and FIG. 4 shows a state of completion of construction.
The extension method of the existing building which concerns on this invention is an extension method of the existing building (1) which has a structure where the some building (2) was connected by the crossing corridor (3) as shown in FIG.

尚、図１では、建物（２）が２棟、渡り廊下（３）が３つである構造の既設建物（１）が示されているが、本発明が適用される既設建物（１）の構造はこれには限定されない。
例えば、建物（２）は複数であればよく、３棟や４棟以上の建物が渡り廊下により接続されているものでもよい。
また、隣り合う建物（２）同士を接続する渡り廊下（３）については、１つでもよいし、２つでもよいし、４つ以上でもよい。渡り廊下（３）が複数ある場合、各渡り廊下は図１に示すように互いに平行に設けられていることが好ましいが、必ずしも互いに平行に設けられていなくてもよい。 FIG. 1 shows an existing building (1) having two buildings (2) and three passages (3), but the structure of the existing building (1) to which the present invention is applied. Is not limited to this.
For example, there may be a plurality of buildings (2), and three or four or more buildings may be connected by a crossing corridor.
Moreover, about the passage corridor (3) which connects adjacent buildings (2), one may be sufficient, two may be sufficient, and four or more may be sufficient. When there are a plurality of crossing corridors (3), it is preferable that the crossing corridors are provided in parallel to each other as shown in FIG. 1, but they are not necessarily provided in parallel to each other.

既設建物（１）の平面視形状は、図１ではローマ数字のIIIの形状を呈しているが、この他にも、平面視形状がII、エ、コ、ロ、日、目、月、田、Ｅ、Ｆ等の形状である既設建物について本発明を適用することが可能である。

Further, the number of floors of the existing building (1) is not limited, and may be one, two, or three or more.

第一実施形態に係る既設建物の増築方法においては、先ず図２に示すように、渡り廊下（３）を挟んだ両側位置において、新たに基礎を設けてその上に柱（鉄骨柱等）を立設し、柱間に梁を架設することにより新規構造物（４）を夫々構築する。
渡り廊下（３）が複数ある場合には、渡り廊下（３）に挟まれた空間（５）に新規構造物（４）を構築する。渡り廊下（３）が３つ以上ある場合には、複数の空間（５）が形成されるので、この場合には、図２に示すように全ての空間（５）に新規構造物（４）を構築することが好ましいが、必ずしも全ての空間（５）に新規構造物（４）を構築する必要はない。 In the extension method of the existing building according to the first embodiment, first, as shown in FIG. 2, a new foundation is provided on both sides of the passageway (3), and columns (steel columns, etc.) are erected on it. And new structures (4) are constructed by laying beams between columns.
When there are a plurality of crossing corridors (3), a new structure (4) is constructed in a space (5) sandwiched between the crossing corridors (3). When there are three or more passage corridors (3), a plurality of spaces (5) are formed. In this case, as shown in FIG. 2, new structures (4) are placed in all the spaces (5). Although it is preferable to construct, it is not always necessary to construct a new structure (4) in every space (5).

渡り廊下（３）を挟んだ両側位置に設けられる新規構築物（４）は、上方に延長されて既設建物（１）の階数よりも１階以上高い上層階部分（６）を有するように構築される。そして、これら渡り廊下（３）を挟んで構築された新規構造物（４）の上層階部分（６）同士を、渡り廊下（３）を跨ぐように梁（７）によって接続することにより、渡り廊下（３）の上方にも上層階部分（６）を形成する（図３参照）。   The new structure (4) provided on both sides of the passageway (3) is constructed so as to have an upper floor part (6) that extends upward and is higher by one floor or more than the number of floors of the existing building (1). . Then, by connecting the upper floor portions (6) of the new structure (4) that is constructed with these passage corridors (3) sandwiched by the beams (7) so as to straddle the passage corridors (3), the passage corridors (3 The upper floor portion (6) is also formed above (see FIG. 3).

最後に、上層階部分（６）を含んで一体化された新規構築物（４）に、天井、床、外壁を設け、内装を施すことにより、既設建物（１）よりも上方へと増築された増築建物（１２）が完成する（図４参照）。   Finally, the new structure (4), which includes the upper floor (6), was integrated with the ceiling, floor, and outer walls, and the interior was decorated, so that the building was extended upward from the existing building (1). The extension building (12) is completed (see FIG. 4).

以上説明した本発明の第一実施形態の増築方法によれば、一連の工程の間、若干の不便は生じるものの、基本的には既設建物（１）をそのまま使用し続けることが可能である。
また、新規構築物（４）を渡り廊下（３）を挟んだ両側位置に設けることにより、既設建物（１）の全体を跨ぐような長スパンの梁を架設する必要がなく、充分な建物強度を確保することができる。更に、渡り廊下（３）により隔てられた建物（２）の間にある空きスペースを有効利用することが可能となる。 According to the extension method of the first embodiment of the present invention described above, it is basically possible to continue using the existing building (1) as it is, although some inconvenience occurs during the series of steps.
In addition, by installing the new structure (4) on both sides across the corridor (3), there is no need to construct long span beams that span the entire existing building (1), ensuring sufficient building strength. can do. Furthermore, it becomes possible to effectively use the empty space between the buildings (2) separated by the crossing corridor (3).

また、図２に示すように、複数の渡り廊下（３）に挟まれた空間（５）に新規構造物（４）を構築することにより、この新規構造物を介して梁（７）を架設することが可能となって、建物強度の向上を図ることができるとともに、デッドスペースであった閉鎖空間（５）を有効利用することが可能となる。   In addition, as shown in FIG. 2, by constructing a new structure (4) in a space (5) sandwiched between a plurality of passageways (3), a beam (7) is erected through the new structure. This makes it possible to improve the building strength and to effectively use the closed space (5) that was a dead space.

本発明においては、複数の渡り廊下（３）が３つ以上の渡り廊下からなる場合、両端以外に位置する渡り廊下の少なくとも１つを撤去した後、この撤去された空間に新規構造物（４）を構築することもできる。
例えば、図２の場合には、中央の渡り廊下を撤去して、この撤去された空間と元々存在していた空間（５）とが合わさった広い空間に、新規構造物（４）を構築することができる。
このようにすると、新規構造物（４）の容積を大きくとることができ、新しく得られる建物の内部容積を大幅に増加させることができる。また、渡り廊下の数が減ることによって、渡り廊下を跨いで構築される上層階部分が減り、建物強度を高めることができる。 In the present invention, when the plurality of passageways (3) are composed of three or more passageways, after removing at least one of the passageways located at positions other than both ends, a new structure (4) is constructed in the removed space. You can also
For example, in the case of FIG. 2, the central passage corridor is removed, and a new structure (4) is constructed in a wide space in which the removed space and the originally existing space (5) are combined. Can do.
If it does in this way, the volume of a new structure (4) can be taken large and the internal volume of the building newly obtained can be increased significantly. Moreover, when the number of crossing corridors decreases, the upper floor part constructed across a crossing corridor decreases, and building strength can be raised.
