【０００１】
【発明の属する技術分野】
本発明は、１棟分のユニット式建物がエキスパンション・ジョイントを介して複数棟連結されている連棟のユニット式建物の連結構造に関する。
【０００２】
【背景技術】
従来、工場で建物を構成する居室等を建物ユニットとして作製しておき、これらの建物ユニットを現場に輸送し、複数の建物ユニットを水平及び垂直方向に組み合わせて建築するようにしたユニット式建物が施工されている。
【０００３】
一方、近年建物ユニットを利用した集合住宅等を得るため、１棟分のユニット式建物をエキスパンション・ジョイントを介して複数棟、例えば２棟連結した連棟のユニット式建物が提案されている。
【０００４】
【発明が解決しようとする課題】
前記連棟のユニット式建物において、隣合うユニット式建物間を連通させて、この連結部分を室内空間として利用したいという要望がある。この場合、連結部分において、雨水が浸入しない防水構造としておく必要がある。
しかし、通常のエキスパンション・ジョイントは、ユニット式建物同士の変位に対応可能なように連結することを主たる機能としているため、雨水に対する防水機能に関しては必ずしも充分ではないこともある。
【０００５】
そこで、本発明は、優れた防水性能を有する連棟のユニット式建物の連結構造を提供することを目的とする。
【０００６】
【課題を解決するための手段】
図面を参照して説明すると、図１、２に示すように、本発明の第１発明に係る連棟のユニット式建物11の連結構造は、複数の建物ユニット15が組み合わされて構成された１棟分のユニット式建物13A,13B がエキスパンション・ジョイント14を介して複数棟連結され、前記各建物ユニット 15 には、上面に勾配屋根ユニット 21A,21B が設けられ、前記勾配屋根ユニット 21A,21B は、屋根フレーム 22 、この屋根フレーム 22 上に載置された下地面材 23 と屋根面材 24 、この屋根面材 24 に張られた防水シート 25 、当該勾配ユニット 21A,21B の端縁に沿って設けられた端縁材 26 及び化粧部材 31 を備えて構成され、前記化粧部材 31 は、前記連結部分側の前記端縁材 26 側面に沿って垂下される垂直部 31A 、前記端縁材 26 上に配置される水平部 31B 、及び、前記屋根面材 24 の下面まで延在した延在部 31C が一体に形成され、隣合う前記勾配屋根ユニット21A,21B間の連結部分に設けられた前記エキスパンション・ジョイント14は、一方のユニット式建物の勾配屋根ユニット21Aに固定された第１のエキスパンション・ジョイント部材28と、他方のユニット式建物の勾配屋根ユニットに固定された第２のエキスパンション・ジョイント部材29とを備えて、これらの第１と第２のエキスパンション・ジョイント部材28,29同士が変位可能に連結され、隣合う前記勾配屋根ユニット21A,21B間に雨樋27が設けられ、前記エキスパンション・ジョイント 14 は、前記勾配屋根ユニット 21A,21B 間の連結部分と、前記化粧部材 31 の垂直部 31A 及び水平部 31B とを被覆して設けられていることを特徴とする。
【０００７】
前記雨樋は、エキスパンション・ジョイント内に浸入した雨水が、更に隣合うユニット式建物間の連結部分に浸入するのを防止するためのものである。
前記第１と第２のエキスパンション・ジョイント部材同士の連結構造に加えて、エキスパンション・ジョイントの下方に雨樋が設けられているため、ユニット式建物間の連結部分における優れた防水性能が得られるようになる。
【０００８】
図６に示すように、本発明の第２発明に係る連棟のユニット式建物の連結構造は、第１発明において、前記エキスパンション・ジョイント14は、第１のエキスパンション・ジョイント部材55と第２のエキスパンション・ジョイント部材56との間に第３のエキスパンション・ジョイント部材57が掛け渡され、第１と第３のエキスパンション・ジョイント部材55,57 同士及び第２と第３のエキスパンション・ジョイント部材同士56,57 がそれぞれ変位可能に連結されていることを特徴とする。
このように、エキスパンション・ジョイントは、３つの部材で構成してもよい。
【０００９】
図２に示すように、本発明の第３発明に係る連棟のユニット式建物11の連結構造は、第１又は第２発明において、連結し合うエキスパンション・ジョイント部材28,29 同士は、一方のエキスパンション・ジョイント部材28の凹部32に他方のエキスパンション・ジョイント部材29の凸部33が嵌合して変位可能に連結されていることを特徴とする。
前記２つのエキスパンション・ジョイント部材同士の凹凸嵌合構造によっても、ユニット式建物間の変位に対応可能である。
【００１０】
図４に示すように、本発明の第４発明に係る連棟のユニット式建物11の連結構造は、第１又は第２発明において、連結し合うエキスパンション・ジョイント部材48,49 同士は、一方のエキスパンション・ジョイント部材49の立ち上がり端部49A と、他方のエキスパンション・ジョイント部材48の立ち下がり端部48A とが当接して変位可能に連結されていることを特徴とする。
図２に示すように、本発明の第５発明に係る連棟のユニット式建物 11 の連結構造は、第１〜第４発明のいずれかにおいて、前記第１のエキスパンション・ジョイント部材は、前記一方のユニット式建物の勾配屋根ユニット側に固定される基部と、垂直立ち上がり部と、前記一方のユニット式建物の勾配屋根ユニットから前記他方のユニット式建物の勾配屋根ユニットに及ぶ中間部と、当該第１のエキスパンション・ジョイント部材の厚さ分の隙間をもって内側に折り返された先端部とが連続して形成されたものであり、前記中間部の端部、及び、前記先端部で形成されたＵ字状部分の凹部を有し、前記第２のエキスパンション・ジョイント部材は、前記他方のユニット式建物の勾配屋根ユニット側に固定される基部と、垂直立ち上がり部と、前記基部と同方向に屈曲した先端部とが連続して形成されたものであり、前記先端部が、前記凹部に嵌合する凸部となっており、前記第２のエキスパンション・ジョイント部材の前記基部と前記第１のエキスパンション・ジョイント部材の前記先端部との凹状の隙間には、バックアップ材とシーリング材が充填されていることを特徴とする。
上記連結構造によれば、エキスパンション・ジョイント 14 は、両部材 28,29 が垂直立ち上がり部 28B,29B を有していることに加えて、両部材 28,29 間の凹状の隙間にバックアップ材 34 およびシーリング材 35 が充填されているため、エキスパンション・ジョイントとしての機能に加えて、防水性能を向上することができる。従って、ユニット式建物 13A,13B 間の連結部分を室内空間として利用する際の防水性能に対する信頼性が高まる。
【００１１】
図３に示すように、本発明の第５発明に係る連棟のユニット式建物11の連結構造は、第１〜第４発明のいずれかにおいて、前記雨樋27は、一方のユニット式建物13A の勾配屋根ユニット21A に固定された第１の雨樋部材43と、他方のユニット式建物13B の勾配屋根ユニット21B に固定された第２の雨樋部材44とを備えて、これらの第１と第２の雨樋部材43,44 の端部同士が変位可能に連結されていることを特徴とする。
前記雨樋部材の端部同士の変位可能な連結構造は、エキスパンション・ジョイントと同様の凹凸嵌合構造、端部同士の当接構造のいずれでもよい。
【００１２】
図３に示すように、本発明の第６発明に係る連棟のユニット式建物11の連結構造は、第１〜第４発明のいずれかにおいて、前記雨樋27は、耐水性シート45よりなり、この耐水性シート45の中央部45C がたるんだ状態でこの耐水性シート45の一方の端部45A が一方のユニット式建物の勾配屋根ユニット21A に固定され、他方の端部45B が他方のユニット式建物の勾配屋根ユニット21B に固定されていることを特徴とする。
前記耐水性シートの弛んだ中央部によってユニット式建物の変位を吸収できるようになる。

Each of the unit type buildings 13A and 13B includes a first floor portion 16 composed of three building units 15, a second floor portion 17 composed of three building units 15 placed on the first floor portion 16, and a gradient roof. 18 is configured.
Each building unit 15 has a frame assembled in a box shape with columns and beams, and a plurality of outer wall materials 19 serving as outer wall surfaces are attached to the frame.
The sloped roof 18 is composed of sloped roof units 21A and 21B provided on the upper surface of each unit type building 15.
[0016]
As shown in FIG. 2, the sloped roof units 21 </ b> A and 21 </ b> B are stretched on a roof frame 22, a base surface material 23 and a roof surface material 24 placed on the roof frame 22, and the roof surface material 24. A waterproof sheet 25, an edge material 26 provided along the edge, and the like are provided.
The expansion joint 14 and the gutter 27 are spanned between the upper surfaces of the two roof units 21A and 21B at the connecting portion of the adjacent slope roof units 21A and 21B.
[0017]
The expansion joint 14 is connected to the first expansion joint member 28 fixed to the roof unit 21A side of the first unit building 13A and the roof unit 21B side of the second unit building 13B. The second expansion joint member 29 is fixed. These expansion joint members 28 and 29 are attached to the edge member 26 via a decorative member 31. The decorative member 31 is formed by integrally forming a vertical portion 31A having a reshaped end portion, a horizontal portion 31B, and an extending portion 31C extending to the lower surface of the roof surface material 24.
[0018]
The first expansion joint member 28 includes a base 28A fixed to the roof unit 21A side of the first building, a vertical rising portion 28B, and a roof unit 21B of the second building from the roof unit 21A of the first building.

A U-shaped portion formed by the end portion of the intermediate portion 28C and the tip end portion 28D serves as a recess 32 that absorbs displacement.
[0019]
On the other hand, the second expansion joint member 29 has a base portion 29A fixed to the roof unit 21B side of the second building, a vertical rising portion 29B, and a tip portion 29C bent in the same direction as the base portion 29A. It is a thing. This leading end portion 29C is a convex portion 33 that fits into the concave portion 32.
A concave gap between the base 29A of the second expansion joint member 29 and the tip 29C of the first member 28 is filled with a backup material 34 and a sealing material 35 for waterproofing.
[0020]
The rain gutter 27 is formed of a first upper edge portion 27A, a square box-shaped groove portion 27B, and a second upper edge portion 27C. The first upper edge portion 27A is disposed on the decorative member 31 on the unit building 13A side of the first building, and is fixed to the end edge member 26 with a bolt 36. The insertion hole of the bolt 36 formed in the first upper edge portion 27A is a long hole for enabling displacement of the sloped roof units 21A and 21B. The second upper edge portion 27C is disposed on the decorative member 31 on the second unit building 13B side. This gutter 27 communicates with a vertical gutter (not shown).
A seal material 37 is interposed in the gap between the decorative member 31 and the expansion joint members 28 and 29.
