Description

【０００１】
【発明の属する技術分野】
この発明は屋根の先端部分を覆った状態に取り付けられた軒先化粧板を備えた建物の軒先構造に関する。
特に、ユニット建物に適した建物の軒先構造に関する。
【０００２】
【従来の技術】
建物の軒先部分はよく人の目を引く場所であり、しかも、この軒先部分には、屋根の先端部や軒樋があって複雑な形状をしていて美観を害することが多い。
この問題を解決する方法として、この屋根の先端部や軒樋を軒先化粧板で覆って美観をよくすることが多く行われている。
【０００３】
一方、ユニット建物は、運搬可能な一定の大きさの箱形の、且つ、内部、外部の仕上げられた建物ユニットと屋根ユニット・屋根パネルとを、予め、工場で製造し、この建物ユニットや屋根ユニット・屋根パネルの複数個を施工現場に運搬し、施工現場で組み立てて建物となすものであって、現場施工期間が短く、且つ、寸法精度の良い標準化された建物となる特徴があることから、近年、広く採用されている。尚、屋根パネルは工場で建物ユニットに取り付けられて施工現場に運搬されることもある。
【０００４】
このユニット建物においても、屋根の先端や軒樋を軒先化粧板で覆って美観をよくすることが多い。
例えば、特公平３−８０２２７号公報や特許第２５４３６２５号公報には、ユニット建物の屋根の先端部や軒樋を軒先化粧板で覆った軒先構造について記載されている。
【０００５】
【発明が解決しようとする課題】
この軒先化粧板の形状については、一般に次のような傾向がある。
即ち、建物の外壁から軒先化粧板の先端までの長さ（以後、庇の出寸法という）は建物の種類、構造、位置や宅地の大きさ等によって異なる。
例えば、敷地にゆとりのある郊外では、庇の出寸法は長く（例えば、７５０ｍｍ〜１０００ｍｍ）、都市部の狭小な宅地では、隣地境界への対応のために短い（例えば、５００ｍｍ以下）。又、同じ建物であっても、南側の屋根では、日光が室内に入るのを防ぐために庇の出寸法を長くするという傾向が多い。
【０００６】
そして、この庇の先端に取り付けられる軒先化粧板は、庇の出寸法が短い場合には垂直方向の長さを長くして豪華にすることで軒先の安定感を持たせることが好ましく、庇の出寸法が長い場合には垂直方向の長さが長いと、側面から見ると、先端部分が大きくなり不安定な感じがするので、垂直方向の長さを短くして、軒先先端の重量感を軽減して建物の外観の向上を図っている。
【０００７】
しかし、建物の南側と北側や東西側とで庇の出寸法が異なる場合に、この庇の出寸法に合わせて軒先化粧材の垂直方向の長さを変えると、それぞれの庇が独立した感じがして全体の調和が取れず見苦しい建物となる。
又、同じ宅地内に２棟以上の建物、例えば、母屋と納屋等があり、この２棟の建物の庇の出寸法が異なる場合にも、庇の出寸法に合わせて軒先化粧材の垂直方向の長さを変えると、全体の調和が取れず見苦しい建物となる。
【０００８】
かかる問題はユニット建物でも発生する。更に、このユニット建物では、ほぼ同じ形状の建物を大量生産して販売するので、例えば、顧客の希望や土地の形状等で庇の長さを変える場合にも、展示場で見た建物と実際に建てた建物の感じが異なると困るので、通常、軒先化粧板の形状と垂直方向の長さをほぼ一定にしている。
【０００９】
上記公報記載のユニット建物について説明すると、特公平３−８０２２７号公報では、通常、庇の出寸法がほぼ５００ｍｍの建物ユニットに使用する軒先化粧材であり、特許第２５４３６２５号公報では、庇の出寸法がほぼ３００ｍｍのユニット建物に使用する軒先化粧板であるが、軒先化粧板の垂直方向の長さはほぼ３７０ｍｍと同じにしている。
上記の場合には庇の出寸法がほぼ５００ｍｍとほぼ３００ｍｍというように余り変わらないので、それほど問題が発生しないが、庇の出寸法が更に大きく（例えば、ほぼ１０００ｍｍ）なると極めて不安定な感じがする。
【００１０】
そこで、この発明の目的は、庇の長さに関係なく垂直方向の長さをほぼ同じにし、しかも、庇の長さが短いときには見る人に豪華な感じを与え、庇の長さが長いときには先端部分が小さく、見る人に安定した感じを与える建物の軒先構造を提供することである。
【００１１】
【課題を解決するための手段】
請求項１の発明は、上記目的を達成するためになしたものであって、建物の屋根の先端部と雨樋の屋外側を覆った状態に取り付けられた板状の軒先化粧板を備えた建物の軒先構造であって、前記軒先化粧板の垂直断面が水平方向の分割線で複数個に分割され、前記分割された軒先化粧板のうちの上側の軒先化粧板であって且つ前記建物の室外方向への突出長さが異なる上側の軒先化粧板を複数用意して、前記突出長さが異なる複数の上側の軒先化粧板の一つを選択して前記分割された下側の軒先化粧板の上に取り付けることにより、前記複数個に分割された軒先化粧板が室外方向に伸長自在になされていることを特徴とするものである。
【００１２】
請求項２記載の発明は、屋根の先端部と雨樋の屋外側を覆った状態に取り付けられた板状の軒先化粧板を備えた建物の軒先構造であって、前記軒先化粧板は、長庇用の軒先化粧板と短庇用の軒先化粧板とからなり、前記長庇用の軒先化粧板は、前記短庇用の軒先化粧板の外形と垂直方向の長さがほぼ同じで、水平方向の区分線で複数個に区分され、この複数個に区分された一部分がその他の部分より突出しており、この短庇用の軒先化粧板と長庇用の軒先化粧板のいずれかが庇の出寸法に応じて選択され取り付けられているものである。
【００１３】
この請求項２記載の発明における長庇用の軒先化粧板は、短庇用の外形と垂直方向の長さがほぼ同じで、水平方向の区分線で複数個に区分され、この複数個に区分された一部分がその他の部分より突出したものである。この際使用する長庇用の軒先化粧板は、突出長さがほぼ一定の１種類だけでもよいが、庇の出寸法に応じて種々な長さに突出した複数種類の軒先化粧板、例えば、庇の出寸法が５００ｍｍ用の長庇用の軒先化粧板や、庇の出寸法が１０００ｍｍ用の長庇用の軒先化粧板等があってもよい。
【００１４】
請求項３記載の発明は、請求項１または２記載の発明に係り、前記建物が複数個の建物ユニットを組み立てたユニット建物であるものである。
【００１５】
（作用）
請求項１記載の発明では、前記軒先化粧板の垂直断面が水平方向の分割線で複数個に分割され、前記分割された軒先化粧板のうちの上側の軒先化粧板であって且つ前記建物の室
外方向への突出長さが異なる上側の軒先化粧板を複数用意して、前記突出長さが異なる複数の上側の軒先化粧板の一つを選択して前記分割された下側の軒先化粧板の上に取り付けることにより、前記複数個に分割された軒先化粧板が室外方向に伸長自在になされているから、庇の長さが長いときには軒先化粧板の一部分を延ばして、その他の部分より突出させ、庇の長さが短いときには伸びている軒先化粧板の一部分を縮める。
【００１６】
すると、この軒先化粧板を正面から見ると、延ばして突出させた部分と突出しない部分との境界がはっきりせず、縮めた軒先化粧板とほぼ同じ外観を呈する。従って、建物の南側と北側と東西側とで庇の出寸法を変えていても、又、母屋と納屋というように同じ宅地内に複数棟がある場合に棟毎に庇の出寸法を変えても、全体が調和し、美麗な建物となる。
【００１７】
又、一部分を延ばして突出させた軒先化粧板を側面から見ると、突出した部分は軒先化粧板の一部分であるために、軒先先端が小さく重量感なく、安定した感じを見る人に与えて美麗である。
【００１８】
請求項２記載の発明では、軒先化粧板は、長庇用の軒先化粧板と短庇用の軒先化粧板とからなり、長庇用の軒先化粧板は、短庇用の軒先化粧板の外形と垂直方向の長さがほぼ同じで、水平方向の区分線で複数個に区分され、この複数個に区分された一部分がその他の部分より突出しており、この短庇用の軒先化粧板と長庇用の軒先化粧板のいずれかが庇の出寸法に応じて選択され取り付けられているから、庇の長さが長いときには一部分がその他の部分より突出した長庇用の軒先化粧板を取り付け、庇の長さが短いときには短庇用の軒先化粧板を取り付ける。
【００１９】
すると、長庇用の軒先化粧板を正面から見ると、突出した部分と突出しない部分との境界がはっきりせず、短庇用の軒先化粧板とほぼ同じ外観を呈する。従って、建物の南側と北側と東西側とで庇の出寸法を変えていても、又、母屋と納屋というように同じ宅地内に複数棟がある場合に棟毎に庇の出寸法を変えても、全体が調和し、美麗な建物となる。
【００２０】
又、長庇用の軒先化粧板を側面から見ると、突出した部分は軒先化粧板の一部分であるために、軒先先端が小さく重量感なく、安定した感じを見る人に与えて美麗である。
【００２１】
請求項３記載の発明では、請求項１または２記載の発明に係るから、請求項１または２記載の発明と同様に、正面からみると長庇用の軒先化粧板と短庇用の軒先化粧板の外観がほぼ同じであり、しかも、長庇用の軒先化粧板を側面からみると先端部が小さく重量感なく安定した感じを見る人に与えて美麗である。
【００２２】
更に、この請求項３記載の発明では、建物が複数個の建物ユニットを組み立てたユニット建物であるから、土地の形状や顧客の要望等で庇の出寸法を変えても、正面から見ると展示場の建物とほぼ同じ感じになるので、必要に応じて安心して庇の長さを選択し、この庇の長さに応じた軒先化粧板を取りつけることができる。
【００２３】
【発明の実施の形態】

【００２４】
図１〜図７において、Ｕはユニット建物であり、このユニット建物Ｕは、図１に示すように、基礎９の上に、９個の建物ユニット１が据え付けられて１階が構成され、この上に、９個の建物ユニット１が据え付けられて２階が構成され、最上階の建物ユニット１の上に屋根パネル２が取り付けられたものである。
建物ユニット１の骨格は、図２に示すように、平面矩形状の四隅に配置した４本の柱１１と、この４本の柱１１の上端部を矩形状の辺に沿って連結した天井梁１３と、この４本の柱１１の下端部を矩形状の辺に沿って連結した床梁１２とからなる。
【００２５】
そして、建物ユニット１は、この骨格の相対する天井梁１３に天井野縁１７が差し渡され、この天井野縁１７の下面に天井材が取り付けられて天井が形成され、相対する床梁１２に床小梁１５が差し渡され、この床小梁１５の上に床根太１６が取り付けられ、この床根太１６の上に床材が取り付けられて床が形成され、壁を設ける場所には、天井梁１３と床梁１２との間に間柱１９が取り付けられ、この間柱１９に壁パネル３が取り付けられて壁が形成されたものである。
【００２６】

屋根パネル２は支持片２１の上に折版屋根材２２を取り付けたものであり、折版屋根材２２の先端は、図３〜図７に示すように、支持片２１より突出している。尚、この折版屋根材２２は屋根のほぼ中央部（棟部分）が一番高く、前後にゆくに従って低くなっている。このときの勾配はほぼ３／１００である。
そして、この屋根パネル２の支持片２１は、図３〜図７に示すように、最上階の建物ユニット１の天井梁１３の長さ方向に一定の間隔を開けてに取り付けられている。
【００２７】

この軒先化粧板４には、短庇用の軒先化粧板４−１と、庇の出寸法が５００ｍｍの長庇用の上側突出軒先化粧板４−２と、庇の出寸法が１０００ｍｍの長庇用の上側突出軒先化粧板４−３と、庇の出寸法が５００ｍｍの長庇用の中側突出軒先化粧板４−４と、庇の出寸法が１０００ｍｍの長庇用の中側突出軒先化粧板４−５の５種類ある。
【００２８】
そして、この短庇用の軒先化粧板４−１は、図３に示すように、フレーム４３−１が天井梁１３にほぼ水平に取り付けられ、このフレーム４３−１が補強板４２−１に取付板４４−１を介して取り付けられ、この補強板４２−１にほぼ垂直な化粧板本体４１−１がビス４９で取り付けられている。この短庇用の軒先化粧板４−１の垂直方向の長さはほぼ３７３ｍｍであり、庇の出寸法はほぼ２８０ｍｍである。
【００２９】
庇の出寸法が５００ｍｍの長庇用の上側突出軒先化粧板４−２を短庇用の軒先化粧板と比較すると、化粧板本体４１−２が、図４に示すように、短庇用の軒先化粧板４−１の化粧板本体４１−１の外形と垂直方向の長さ（ほぼ３７３ｍｍ）とほぼ同じで、水平方向の区分線で上側部分４１−２ａと下側部分４１−２ｂとに２分割され、上側部分４１−２ａが下側部分４１−２ｂより突出していて、フレーム４３−２の室内側の一端から化粧板本体４１−２の先端までの長さ（庇の出寸法）がほぼ５００ｍｍとなっていることが異なる。
【００３０】
尚、この上側部分４１−２ａと下側部分４１−２ｂとは軒天板４５−２で連結されている。又、フレーム４３−２は室内側フレーム４３−２ａと、この上側に取り付けられ、室外方向に突出した室外側フレーム４３−２ｂとからなり、室外側フレーム４３−２ｂの位置が上方に移動した状態になり、化粧板本体４１−２の上側部分４１−２ａが取り付け易くなっている。
【００３１】
そして、この庇の出寸法が５００ｍｍの長庇用の上側突出軒先化粧板４−２の化粧板本体４１−２は、図４に示すように、室内側フレーム４３−２ａが天井梁１３にほぼ水平に取り付けられ、フレーム４３−２ｂが補強板４２−２に取付板４４−２を介して取り付けられ、この補強板４２−２に上側部分４１−２ａがビス４９で取り付けられている。
【００３２】
庇の出寸法が１０００ｍｍの長庇用の上側突出軒先化粧板４−３を出寸法が５００ｍｍの長庇用の上側突出軒先化粧板４−２と比較すると、図５に示すように、上側部分４１−３ａが下側部分４１−３ｂより更に長く突出していて、フレーム４３−３の室内側の一端から化粧板本体４１−３の先端までの長さ（庇の出寸法）がほぼ１０００ｍｍとなっていることが異なる。その他は出寸法が５００ｍｍの長庇用の上側突出軒先化粧板４−２とほぼ同じである。
【００３３】
庇の出寸法が５００ｍｍの長庇用の中側突出軒先化粧板４−４を短庇用の軒先化粧板４−１と比較すると、化粧板本体４１−４が、図６に示すように、短庇用の軒先化粧板４−１の化粧板本体４１−１の外形と垂直方向の長さ（ほぼ３７３ｍｍ）とほぼ同じで、水平方向の２本の区分線で上側部分４１−４ａ、中側部分４１−４ｃ、下側部分４１−４ｂに３分割され、中側部分４−４ｃが上側部分４−４ａや下側部分４−４ｂより突出していて、フレーム４３−４の室内側の一端から化粧板本体４１−４の先端までの長さ（庇の出寸法）がほぼ５００ｍｍとなっていることが異なる。
【００３４】
尚、この上側部分４１−４ａと中側部分４１−４ｃとは屋根板４６−４で連結され、中側部分４１−４ｃと下側部分４１−４ｂとは軒天板４５−４で連結されている。
そして、この出寸法が５００ｍｍの長庇用の中側突出軒先化粧板４−４の化粧板本体４１−４は、上側部分４１−４ａに補強板４２−４ａが、又、中側部分４１−４ｃには補強板４２−４ｃがそれぞれビス４９−４ａ、４９−４ｃで取り付けられ、この補強板４１−４ａ、４１−４３ｃがそれぞれ天井梁１３に取り付けられているフレーム４３−４に取付板４４−４ａ、４４−４ｃを介して取り付けられている。
【００３５】
出寸法が１０００ｍｍの長庇用の中側突出軒先化粧板４−５を出寸法が５００ｍｍ用の長庇用の中側突出軒先化粧板４−４と比較すると、図７に示すように、中側部分４１−５ｃが上側部分４１−５ａや下側部分４１−５ｂより更に長く突出していて、フレーム４３−５の室内側の一端から化粧板本体４１−５の先端までの長さ（庇の出寸法）がほぼ１０００ｍｍとなっていることが異なる。その他は出寸法が５００ｍｍの長庇用の中側突出軒先化粧板４−４とほぼ同じである。
【００３６】
このように、上記５種類の軒先化粧板４は化粧板本体４１の垂直方向の長さはほぼ同じであるが、長庇用の軒先化粧板４−２、４−３、４−４、４−５は、化粧板本体４１の一部分が突出している。
従って、この軒先化粧板４を正面から見ると、突出下部分と突出しない部分との境界がハッキリせず、短庇用の軒先化粧板４−１と長庇用の軒先化粧板４−２、４−３、４−４、４−５とほぼ同じ外観を呈する。又、側面からみると、突出した部分は化粧板本体４１の一部分であるために、軒先が小さく重量感がなく安定した感じを人に与えて美麗である。
【００３７】
５は軒樋であり、この軒樋５は、折版屋根材２２の先端の下方に位置した状態にフレーム４３の上側に載せられて取り付けられ、折版屋根２から落下した雨水を受けるようになっている。
６は軒樋５からほぼ垂直に下方に取り付けられた竪樋であり、この竪樋６は軒樋５に落下した雨水を地上に導くものである。
７は連結屋根であり、この連結屋根７は化粧板本体４１の上端と折版屋根２２とを連結し、この間から雨水が漏れることを防ぐものであり、この連結屋根７の上に降った雨水は折版屋根２２の方向に流れてゆくようになっている。
【００３８】
次に、このユニット建物Ｕの施工方法および軒先化粧板４の作用について説明する。
先ず、工場で、図２に示すように、平面矩形状の四隅に４本の柱１１を配置し、この４本の柱１１の上端部を天井梁１３で矩形状の辺に沿って連結し、この４本の柱１１の下端部を床梁１２で矩形状の辺に沿って連結した建物ユニット１の骨格を製造する。
【００３９】
一方、鋼製四角筒状のフレーム３１の室外側に硬質木片セメント板３２を取り付けて壁パネル３を製造する。
建物ユニット１の骨格の相対する天井梁１３に天井野縁１７を差し渡し、この天井野縁１７の下面に天井材を取り付けて天井を形成し、相対する床梁１２に床小梁１５を差し渡し、この床小梁１５の上に床根太１６を取り付け、この床根太１６の上に床材を取り付けて床を形成し、壁を設ける場所には、天井梁１３と床梁１２との間に間柱１９を取り付け、この間柱１９に壁パネル３のフレーム３１を取り付けて壁を形成したり、その他種々な仕上げを行って建物ユニット１を製造する。
【００４０】
又、屋根材２２、支持片２１、化粧板本体４１、補強板４２、取付板４３、連結屋根７等を製造する。
このようにして製造した建物ユニット１、支持片２１、屋根材２２、化粧板本体４１、補強板４２、取付板４３、連結屋根７等を施工現場に運搬する。
施工現場では、予め設けられている基礎９の上に９個の建物ユニット１を据え付けて１階を構成し、この上に、９個の建物ユニット１を据え付けて２階を構成し、最上階の建物ユニット１の天井梁１３に支持片２１を取り付け、この支持片２１の上に折版屋根材２２を取り付ける。
【００４１】
この際、この折版屋根材２２のほぼ中央部を一番高くし、前後にゆくに従って低くし、折版屋根材２２の先端を、図３〜図７に示すように、支持片２１より突出させておく。
次に、フレーム４３を天井梁１３にほぼ水平に突出させて取り付け、このフレーム４３に補強板４２を取付板４４を介して取り付け、この補強板４２に化粧板本体４１をビス４９で取り付けて、軒先化粧板４を取り付ける。
【００４２】
この際、建物の種類、構造、位置や宅地の大きさ等に合った庇の出寸法を有する軒先化粧板４を、図３〜図７に示す５種類の中から選んで取り付ける。
その後、軒樋５をフレーム４３の上側に載せて取り付けたり、竪樋６や連結屋根７を取り付けたり、その他の仕上げを行うとユニット建物Ｕが完成する。
このユニット建物Ｕの折版屋根材２２の上に降った雨水は、折版屋根２２の上を流れて行って、折版屋根２２の先端から落下し、軒樋５、竪樋６を通って地上に落下する。
【００４３】
又、化粧板本体４１と折版屋根２２の間に降った雨水は連結屋根７から折版屋根２２の方向に流れてゆき、その後は折版屋根２の上に降った雨水と一緒になって地上に落下する。
【００４４】
このようにして完成したユニット建物Ｕでは、建物の種類、構造、位置や宅地の大きさ等に合った庇の出寸法を有する軒先化粧板４を、図３〜図７に示す５種類の中から選んで取り付けているから、ユニット建物Ｕは、南側と北側と東西側とで庇の出寸法を変えていても、又、母屋と納屋というように同一宅地内に複数棟の建物がある場合に棟毎に庇の出寸法を変えていても、長庇用の軒先化粧板４−２、４−３、４−４、４−５を正面から見ると、突出した部分と突出しない部分との境界がはっきりせず、短庇用の軒先化粧板４−１とほぼ同じ外観を呈し、ユニット建物Ｕの全体が調和し、美麗な建物となる。
【００４５】
又、長庇用の軒先化粧板４−２、４−３、４−４、４−５を側面から見ると、突出した上側部分４１−２ａ、４１−３ａや中側部分４１−４ｃ、４１−５ｃは軒先化粧板４−２、４−３、４−４、４−５の一部分であるから、軒先先端部が小さく重量感なく、見る人に安定した感じを与えて美麗である。
このように、土地の形状や顧客の要望等で庇の出寸法を変えても、正面から見ると展示場の建物とほぼ同じ感じになるので、必要に応じて安心して庇の長さを選択し、この庇の長さに応じた軒先化粧板４を取り付けることがきる。
【００４６】
【発明の効果】
請求項１記載の発明では、前記軒先化粧板の垂直断面が水平方向の分割線で複数個に分割され、前記分割された軒先化粧板のうちの上側の軒先化粧板であって且つ前記建物の室外方向への突出長さが異なる上側の軒先化粧板を複数用意して、前記突出長さが異なる複数の上側の軒先化粧板の一つを選択して前記分割された下側の軒先化粧板の上に取り付けることにより、前記複数個に分割された軒先化粧板が室外方向に伸長自在になされているから、庇の長さが長いときには軒先化粧板の一部分を延ばして、その他の部分より突出させ、庇の長さが短いときには伸びている軒先化粧板の一部分を縮める。
【００４７】
すると、この軒先化粧板を正面から見ると、延ばして突出させた部分と突出しない部分との境界がはっきりせず、縮めた軒先化粧板とほぼ同じ外観を呈する。従って、建物の南側と北側と東西側とで庇の出寸法を変えていても、又、母屋と納屋というように同じ宅地内に複数棟がある場合に棟毎に庇の出寸法を変えても、全体が調和し、美麗な建物となる。
【００４８】
又、一部分を延ばして突出させた軒先化粧板を側面から見ると、突出した部分は軒先化粧板の一部分であるために、軒先先端が小さく重量感なく、安定した感じを見る人に与えて美麗である。
【００４９】
請求項２記載の発明では、軒先化粧板は、長庇用の軒先化粧板と短庇用の軒先化粧板とからなり、長庇用の軒先化粧板は、短庇用の軒先化粧板の外形と垂直方向の長さがほぼ同じで、水平方向の区分線で複数個に区分され、この複数個に区分された一部分がその他の部分より突出しており、この短庇用の軒先化粧板と長庇用の軒先化粧板のいずれかが庇の出寸法に応じて選択され取り付けられているから、庇の長さが長いときには一部分がその他の部分より突出した長庇用の軒先化粧板を取り付け、庇の長さが短いときには短庇用の軒先化粧板を取り付けるから、長庇用の軒先化粧板を正面から見ると、短庇用の軒先化粧板とほぼ同じ外観を呈する。従って、建物の南側と北側と東西側とで庇の出寸法を変えていても、又、母屋と納屋というように同一宅地内に複数棟の建物がある場合に棟毎に庇の出寸法を変えていても、全体が調和し、美麗な建物となる。
【００５０】
又、長庇用の軒先化粧板を側面から見ると、突出した部分は軒先化粧板の一部分であるために、軒先先端部が小さく重量感なく、見る人に安定した感じを与えて美麗である。
【００５１】
請求項３記載の発明では、請求項１記載の発明に係るから、請求項１記載の発明と同様に、正面からみると長庇用の軒先化粧板と短庇用の軒先化粧板の外観がほぼ同じであり、しかも、側面から見ると長庇用の軒先化粧板の先端部が小さく重量感なく見る人に安定した感じを与えて美麗である。
【００５２】
更に、この請求項２記載の発明では、建物が複数個の建物ユニットを組み立てたユニット建物であるから、土地の形状や顧客の要望等で庇の出寸法を変えても、正面から見ると展示場の建物とほぼ同じ感じになるので、必要に応じて安心して庇の長さを選択し、この庇の長さに応じた軒先化粧板を取り付けることがきる。

BACKGROUND OF THE INVENTION
The present invention relates to an eaves-end structure of a building provided with an eaves-end decorative plate attached in a state of covering a front end portion of a roof.
In particular, the present invention relates to a building eaves structure suitable for a unit building.
[0002]
[Prior art]
The eaves part of the building is often a place that attracts people's eyes, and the eaves part has a roof tip and an eaves wall and has a complicated shape, which often impairs the beauty.
As a method for solving this problem, it is often performed to improve the aesthetics by covering the end of the roof or the eaves with a decorative eaves.
[0003]
On the other hand, a unit building is manufactured in a factory in the form of a box of a certain size that can be transported and finished inside and outside, and roof units and roof panels. Because multiple units and roof panels are transported to the construction site and assembled at the construction site to form a building, the construction period is short, and the standard building has good dimensional accuracy. In recent years, it has been widely adopted. The roof panel may be attached to the building unit at the factory and transported to the construction site.
[0004]
Even in this unit building, the top of the roof and the eaves are often covered with an eaves veneer to improve the beauty.
For example, Japanese Patent Publication No. 3-80227 and Japanese Patent No. 2543625 describe an eaves end structure in which a roof end of a unit building and an eaves wall are covered with an eaves end decorative plate.
[0005]
[Problems to be solved by the invention]
About the shape of this eaves-end decorative board, there exists the following tendency generally.
That is, the length from the outer wall of the building to the front edge of the eaves decorative plate (hereinafter referred to as the protruding dimension of the eaves) differs depending on the type, structure, position, size of the residential land, and the like.
For example, in the suburbs where there is a lot of space on the site, the protruding size of the fence is long (for example, 750 mm to 1000 mm), and in a small residential land in an urban area, it is short (for example, 500 mm or less) to cope with the boundary of the adjacent land. Even in the same building, the roof on the south side tends to lengthen the ridge length to prevent sunlight from entering the room.
[0006]
The eaves decorative plate attached to the tip of the heel preferably has a sense of stability of the eaves by making the vertical length longer and gorgeous when the heel protrusion dimension is short. If the protruding dimension is long, the vertical length is long, and when viewed from the side, the tip becomes large and feels unstable. It is reduced to improve the appearance of the building.
[0007]
However, if the heel protrusion dimensions are different on the south side, north side, and east-west side of the building, changing the vertical length of the eaves decorative material according to the heel protrusion dimension will make each heel feel independent. It becomes an unsightly building because the overall harmony cannot be achieved.
In addition, when there are two or more buildings in the same residential land, such as a main building and a barn, and the protruding dimensions of the eaves of these two buildings are different, the vertical direction of the eaves decorative material according to the protruding dimensions of the eaves If the length of the building is changed, the overall harmony cannot be achieved and the building becomes unsightly.
[0008]
Such a problem also occurs in unit buildings. In addition, this unit building mass-produces and sells buildings with almost the same shape. For example, even when changing the length of the fence depending on the customer's wishes or the shape of the land, it is the same as the building seen in the exhibition hall. Because the feeling of the building built in is different, usually the shape of the eaves decorative plate and the length in the vertical direction are made almost constant.
[0009]
The unit building described in the above publication will be described. In Japanese Patent Publication No. 3-80227, it is a decorative material for eaves that is usually used for a building unit having a protruding dimension of approximately 500 mm. In Japanese Patent No. 2543625, an This is an eaves edge decorative plate used for a unit building having a dimension of about 300 mm, and the vertical length of the eaves edge decorative plate is set to be approximately 370 mm.
In the above case, the protrusion size of the wrinkles does not change so much as about 500 mm and about 300 mm, so that the problem does not occur so much, but if the protrusion size of the wrinkles becomes larger (for example, about 1000 mm), it feels extremely unstable. To do.
[0010]
Therefore, the object of the present invention is to make the vertical length almost the same regardless of the length of the heel, and to give the viewer a luxurious feeling when the heel length is short, and when the heel length is long. It is to provide a building eaves structure that has a small tip and gives the viewer a stable feeling.
[0011]
