Description

【0001】
【発明の属する技術分野】
本発明は、ユニット式建物に係り、特に、大型の戸建て住宅や集合住宅に利用できる。
【0002】
【背景技術】
従来より、戸建て住宅や集合住宅のなかには、工場で生産された複数の建物ユニットを建築現場で組み合わす、いわゆる、ユニット工法により建てられるものがある。通常、このようなユニット工法で建てられるユニット式建物は、建築現場で打設される基礎と、この基礎上で複数の建物ユニットを組み合わすことにより形成される建物部と、この建物部の上部に設けられる屋根部とから構成されている。
【0003】
【発明が解決しようとする課題】
ところで、各建物ユニットには工場での生産時に微小な寸法誤差が生じるため、特に、多くの建物ユニットを水平方向に連続して組み合わせる場合には、それら建物ユニットの累積誤差により、建物部としての水平方向の寸法が許容範囲外となってしまう虞がある。このため、水平方向に組み合わされる建物ユニットの数は、建物部の水平方向の寸法が許容範囲にとどまるように制限されているのが一般的であり、例えば、平面長方形の建物ユニットでは、建物全体の構造バランスをも考慮して、互いの長辺側を対向させる方向には最大六つ、互いの短辺側を対向させる方向には最大四つ、に制限されている。
従って、ユニット工法では、水平方向に組み合わされる建物ユニットの数が制限されるため、これを超えるような建物ユニットの組合せを行って一つの大きな戸建て住宅や集合住宅を建てることは困難であった。
【0004】
本発明の目的は、水平方向に組み合わせる建物ユニットの数に制限されることなく大きくできるユニット式建物を提供することにある。
【0005】
【課題を解決するための手段】
本発明のユニット式建物は、図面を参照して説明すると、連続する一つの基礎11上に建てられて水平方向に離隔した複数の建物部12を有し、かつ、これらの建物部12が上下方向および水平方向に組み合わされた複数の建物ユニット14〜16を含んで構成されているユニット式建物であって、複数の建物部12のうちの互いに隣設対向する一対の建物部12をエキスパンション・ジョイント20で連結するとともに、このエキスパンション・ジョイント20を、一対の建物部12の対向壁17にこれら対向壁17間に突出して設けた支持部21と、これら支持部21に架け渡したジョイント部材22とを含んで構成し、このジョイント部材22と各対向壁17の少なくとも一方の壁に設けられた支持部21とのうちのいずれか一方に、ジョイント部材22の架け渡し方向に長い長孔27を設け、これらジョイント部材22と支持部21とを長孔27に係合する係合部材29を介してジョイント部材22の架け渡し方向に移動自在に連結し、ジョイント部材22を、上部に設けられた支持部21間に架け渡される天井用連結部材23と、下部に設けられた支持部21間に架け渡される床用連結部材24とを含んで構成し、これら天井用連結部材23および床用連結部材24を、当該天井用連結部材23および床用連結部材24が配置される階層の建物ユニット14〜16が積重された段階で支持部21間に架け渡し、最上階層に配置された天井用連結部材23には、一対の建物部12の各屋根部13と連続する屋根用連結部材26を設けことを特徴とする。
【0006】
このような本発明においては、各建物部12は構造的に独立しているが、エキスパンション・ジョイント20で連結されることにより、全体で一つのユニット式建物10を構成すようになる。この際、個々の建物部12を従来のユニット式建物の制限内で建てるとしても、各建物部12の建物ユニット14〜16による水平方向の累積誤差はエキスパンション・ジョイント20により許容されるから、それら建物部12が制限なく連結可能になり、建物全体としては水平方向に配設される建物ユニット14〜16の数に制限がなくなる。このため、建物全体が従来にない一つの大きなユニット式建物10となる。
【0007】
そして、支持部21を対向壁17における建物部12の各階層に対応した部分の上部と下部とに設け、ジョイント部材22を、天井用連結部材23と床用連結部材24とにおける各対向壁17とは直角なす側に架け渡す側壁用連結部材25を含んで構成したことを特徴とする。
このような場合、対向壁17間には外部と各連結部材23〜25で仕切られた空間が階層毎に形成されるようになり、この空間を利用して居室や、建物部間を移動する廊下、あるいは、内階段等を設けることが可能になる。
【0008】
【発明の実施の形態】
以下、本発明における第一の実施の形態を図面に基づいて説明する。
図1には、本実施の形態に係るユニット式建物10が示されている。図2には、図1におけるII−II線断面が示されている。図3には、図1における矢印III の部分が拡大されて示されている。
図1〜図3において、ユニット式建物10は三階建ての集合住宅であり、建築現場において連続して打設された一つの基礎11と、この基礎11上に互いに離隔して建てられた二つの建物部12と、これら建物部12の上部に設けられた屋根部13とを含んで構成されている。
【0009】
各建物部12は基礎11上に配置された複数の一階建物ユニット14と、これら一階建物ユニット14の上部に積重された複数の二階建物ユニット15と、さらに、これら二階建物ユニット15の上部に積重された三階建物ユニット16とから構成されている。具体的には、各一〜三階建物ユニット14〜16は、平面長方形をした建物ユニットであり、互いの長辺側が対向する方向に六つ、互いの短辺側が対向する方向に四つ、合計二十四のユニットが水平方向に連続して組み合わされて各階層を形成している。
【0010】
また、これら建物部12はエキスパンション・ジョイント20によって連結されている。このエキスパンション・ジョイント20は、各建物部12における対向壁17の上部と下部とにこれら対向壁17間に突出して設けられた複数の支持部21と、これら支持部21に架け渡されたジョイント部材22とから構成され、このジョイント部材22は、上部の支持部21間に架け渡された天井用連結部材23と、下部の支持部21間に架け渡された床用連結部材24と、これら天井用連結部材23と床用連結部材24とにおける各対向壁17とは直角なす側に各々架け渡された側壁用連結部材25とを含んで構成されている。天井用連結部材23の上部には各建物部12の屋根部13と連続した屋根用連結部材26が設けられ、各側壁用連結部材25が各建物部12における対向壁17と直角をなす側壁18と建物前後方向(図2中の矢印Xの方向)の同一の位置に配設されている。
【0011】
床用連結部材24には、両方の対向壁17に設けられた支持部21に対応し、かつ、床用連結部材24の架け渡し方向に長い長孔27が穿設されている。一方、各支持部21には長孔27に対応してこの長孔27と直交する方向に長い別の長孔28が穿設されている。そして、長孔27、28には上方から係合部材であるボルト29が挿通され、ナット30と螺合するようになっている。31はワッシャーである。すなわち、この床用連結部材24と支持部21とは、ボルト29が長孔27、28に係合した状態で床用連結部材24の架け渡し方向およびこれと直角な方向に移動自在に連結されている。なお、図示を省略するが、天井用連結部材23も同様な構造である。
ここで、以上の各連結部材23〜26と建物部12との隙間には図示略のバックアップ材やコーキング材等が介装され、各連結部材23〜25で囲まれた内部空間に対する防水処理が施されている。
【0012】
このような本実施の形態においては、建築現場に基礎11を設けておくとともに、一〜三階建物ユニット14〜16を工場で生産する。そして、これらの一〜三階建物ユニット14〜16を建築現場にトラック等で運び、クレーンの吊り込み作業により基礎11上に建物部12を形成する。この際、一階建物ユニット14、三階建物ユニット16のうちの対向壁17を形成する部分に予め工場で支持部21を設けておき、建築現場で一階建物ユニット14を配置した段階で支持部21間に床用連結部材24を架け渡し、三階建物ユニット15を配設した段階で天井用連結部材23を架け渡す。次いで、建物部12、天井用連結部材23の上部に屋根用連結部材26を設けるとともに、側壁用連結部材25を取り付ける。最後に防水処理を施してユニット式建物10を完成させる。
【0013】
このような本実施の形態によれば以下のような効果がある。
すなわち、各建物部12は構造的に独立しているが、エキスパンション・ジョイント20で連結されているため、全体で一つのユニット式建物10を構成するようになる。この際、各建物部12を従来のユニット式建物の制限内で建てるとしても、一〜三階建物ユニット14〜16による水平方向の累積誤差はエキスパンション・ジョイント20で許容されるため、建物部12同士の連結を問題なく行え、これにより、ユニット式建物10を、全体として一〜三階建物ユニット14〜16が従来の規定数以上に配設された一つ大きな建物にできる。
【0014】
また、このエキスパンション・ジョイント20の要部は、支持部21間に天井用連結部材23、床用連結部材24を架け渡し、ボルト29を天井用連結部材23、床用連結部材24と支持部21との長孔27、28に係合させる簡単な構造であるから、各建物部12をこのエキスパンション・ジョイント20で連結する際には、天井用連結部材23、床用連結部材24の架け渡し作業を、クレーンを使用して各ユニットの吊り込み作業と平行して行えるうえ、ボルト29を係合させるだけでよいため、各建物部12の連結作業を容易かつ効率的に行うことができる。
【0015】
そして、エキスパンション・ジョイント20のジョイント部材22は、天井用連結部材23、床用連結部材24、側壁用連結部材25とを含んで構成されているため、各建物部12の対向壁17間に各連結部材23〜25で囲まれた空間を形成でき、この空間を所望の用途に応じて有効利用することができる。
【0016】
さらに、天井用連結部材23の上部に設けられた屋根用連結部26が各建物部12の屋根部13と連続し、側壁用連結部材17が各建物部12の側壁18と面一となっているため、建物全体の外観を良好にできる。
【0017】
また、天井用連結部材23、床用連結部材24の長孔27は各建物部12の両方の対向壁17に設けられた支持部21に対応して穿設されているため、支持部21間に天井用連結部材23、床用連結部材24を架け渡す際の長孔27と別の長孔28との位置合せも簡単に行うことができ、各建物部12の連結作業を一層容易に行うことができる、
【0018】
そして、支持部21に穿設された長孔28は長孔27に対して直角方向に長いため、建物部12の各々において、ジョイント部材22の架け渡し方向に対して直角方向の累積誤差がある場合でも、これらの累積誤差がこの長孔28で吸収され、これにより各建物部12を確実に連結することができる。
【0019】
さらに、建物部12同士がエキスパンション・ジョイント20で連結されているため、ユニット式建物10を耐震性に優れた建物とすることができる。
【0020】
図4には、本発明における第二の実施の形態が示されている。
本実施の形態において、ユニット式建物40のエキスパンション・ジョイント20は、支持部21が対向壁17における建物部12の各階層に対応した部分の上部と下部とに設けられている。各階層における上部の支持部21間には天井用連結部材23が架け渡され、下部の支持部21間には床用連結部材24が架け渡され、これら天井用連結部材23と床用連結部材24とにおける対向壁17とは直角なす側には、上下方向の大きさが各階層に対応する大きさとされた側壁用連結部材25が架け渡されている。
すなわち、エキスパンション・ジョイント20内に形成される空間は、天井用連結部材23と床用連結部材24とによって各階層に仕切られており、各階層の空間42は対向壁17に設けられたドア43により各建物部12内と連通している。
なお、ユニット式建物40を構成する他の構成部材は、前述した第一の実施の形態のユニット式建物と同じであり、ここでは、それらに同一符号を付して説明を省略する。
このような本実施の形態では、各階の空間42を建物部12間を移動するための廊下、あるいは、居室としても利用することができる。
【0021】
図5には、本発明には含まれないが、本発明と関連した技術として、第三の実施の形態が示されている。
本実施の形態では、ユニット式建物50のエキスパンション・ジョイント60は、対向壁17の上部にのみ設けられた支持部21と、これら支持部21間に架け渡されたジョイント部材62としての天井用連結部材23とを有し、この天井用連結部材23の上部には屋根用連結部材26が設けられている。そして、対向壁17間には、基礎11に直接設置され、かつ、エキスパンション・ジョイント60から独立した階段70が設けられており、この階段70とドア43により各階の連絡ができるようになっている。
【0022】
なお、本発明は各前記実施の形態に限定されるものではなく、本発明の目的を達成できる他の構成等を含み、以下に示すような変形等も本発明に含まれる。
【0023】
例えば、前記第三の実施の形態では、階段70が基礎11上に直接設置されてることによりエキスパンション・ジョイント60から独立していたが、本発明に係る階段としては、基礎11に直接設置されているのではなく、例えば、エキスパンション・ジョイントを前述の第一の実施の形態のように天井用連結部材、床用連結部材、側壁用連結部材を含んで構成し、これらの連結部材で囲まれた空間内に設けられる。このような場合には、階段をユニット式建物50内に設けられた内階段とすることができる。
【0024】
また、前記第一、第二の実施の形態では、屋根用連結部材26が各建物部12の屋根部13と連続し、側壁用連結部材25が各建物部12の側壁18と面一になっていたが、本発明に係る、屋根用連結部材や側壁用連結部材は、特に、各建物部12の屋根部13と連続させたり、側壁18と面一にしなくともよい。
しかしながら、そうすることにより、前述の効果が得られるので好ましい。
【0025】
そして、前記各実施の形態では、エキスパンション・ジョイント20、60を構成する天井用連結部材23の下方には、各連結部材23〜25で囲まれた空間が形成されたり、あるいは、階段70が設けられているが、本発明に係るエキスパンション・ジョイントは、建物部12の最上階層に設けられた支持部21と、これら支持部21に架け渡される天井用連結部材23とで構成するだけでもよく、このような場合には、天井用連結部材23の上部に屋根用連結部材26を設けることにより、ユニット式建物を全体門型の建物にできる。
【0026】
さらに、前記各実施の形態では、ジョイント部材22、62の架け渡し方向に長い長孔27がジョイント部材22、62に穿設され、この長孔27に対して直角方向に長い別の長孔28が支持部21に穿設されていたが、長孔27を支持部21に穿設し、長孔28をジョイント部材22、62に穿設してもよい。
また、本発明においては、長孔28は必須のものではなく、適宜省略可能である。しかしながら、長孔28を穿設することにより前述した効果が得られるのでよい。
【0027】
また、前記各実施の形態では、ユニット式建物10、40、50が集合住宅であったが、本発明に係るユニット式建物は集合住宅に限定されるものではなく、戸建ての住宅等であってもよい。
【0028】
【発明の効果】
以上に述べたように本発明によれば、個々の建物部を従来のユニット式建物の制限内で建てるとしても、各建物部の建物ユニットによる水平方向の累積誤差がエキスパンション・ジョイントにより許容されるため、それら建物部の数を制限なく建てることが可能になり、建物全体としては水平方向の建物ユニットの数に制限がなくなる。このため、建物全体を一つの大きなユニット式建物にできるという効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a unit-type building, and can be used particularly for a large-sized detached house and an apartment house.
[0002]
[Background]
Conventionally, some detached houses and apartment houses are built by a so-called unit method in which a plurality of building units produced at a factory are combined at a construction site. Usually, a unit type building built by such a unit method is composed of a foundation placed on a construction site, a building part formed by combining a plurality of building units on this foundation, and an upper part of this building part. It is comprised from the roof part provided in.
[0003]
[Problems to be solved by the invention]
By the way, each building unit has a small dimensional error during production at the factory. Especially when many building units are combined continuously in the horizontal direction, the accumulated error of these building units causes There is a risk that the horizontal dimension may be outside the allowable range. For this reason, the number of building units combined in the horizontal direction is generally limited so that the horizontal dimension of the building portion remains within an allowable range. In consideration of the structural balance, the maximum is limited to six in the direction in which the long sides face each other, and the maximum is four in the direction in which the short sides oppose each other.
Therefore, in the unit method, since the number of building units combined in the horizontal direction is limited, it is difficult to build one large detached house or apartment house by combining building units exceeding this.
[0004]
An object of the present invention is to provide a unit building that can be enlarged without being limited by the number of building units combined in the horizontal direction.
[0005]
[Means for Solving the Problems]
The unit type building of the present invention will be described with reference to the drawings. The unit type building has a plurality of building parts 12 that are built on one continuous foundation 11 and spaced apart in the horizontal direction. A unit type building configured to include a plurality of building units 14 to 16 combined in a horizontal direction and a horizontal direction, and a pair of building parts 12 adjacent to each other among the plurality of building parts 12 are expanded. The expansion joint 20 is connected by the joint 20, and the expansion joint 20 is provided on the opposing walls 17 of the pair of building parts 12 so as to protrude between the opposing walls 17, and the joint member 22 spanning the support parts 21. In any one of this joint member 22 and the support part 21 provided in at least one wall of each opposing wall 17, A long long hole 27 is provided in the crossing direction of the joint member 22, and the joint member 22 and the support portion 21 are movable in the crossing direction of the joint member 22 via an engaging member 29 that engages the long hole 27. The joint member 22 includes a ceiling connecting member 23 that spans between the support portions 21 provided in the upper portion, and a floor connecting member 24 that spans between the support portions 21 provided in the lower portion. The ceiling connecting member 23 and the floor connecting member 24 are configured, and the support unit 21 is formed at the stage where the building units 14 to 16 in the layer where the ceiling connecting member 23 and the floor connecting member 24 are arranged are stacked. The ceiling connecting member 23 that is bridged between them and arranged in the uppermost layer is provided with a roof connecting member 26 that is continuous with each roof portion 13 of the pair of building portions 12.
[0006]
In the present invention, the building parts 12 are structurally independent, but are connected by the expansion joint 20 to constitute one unit building 10 as a whole. At this time, even if the individual building parts 12 are built within the limits of the conventional unit type building, since the horizontal joint error by the building units 14 to 16 of each building part 12 is allowed by the expansion joint 20, The building part 12 can be connected without limitation, and the number of building units 14 to 16 disposed in the horizontal direction as a whole building is not limited. For this reason, the whole building turns into one large unit type building 10 which has not existed conventionally.
[0007]
And the support part 21 is provided in the upper part and the lower part of the part corresponding to each hierarchy of the building part 12 in the opposing wall 17, and the joint member 22 is each opposing wall 17 in the connection member 23 for ceilings, and the connection member 24 for floors. Is characterized in that it includes a side wall connecting member 25 that spans the right angle side.
In such a case, a space partitioned by the outside and the connecting members 23 to 25 is formed between the opposing walls 17 for each level, and the space is used to move between living rooms and building parts. It becomes possible to provide a corridor or an internal staircase.
[0008]
