Description

【０００１】
【発明の属する技術分野】
本発明は、住宅の増築時の屋根工事に際し、作業の簡易化を図ることができる隅木梁の設置工法に関する。
【０００２】
【従来の技術】
寄棟造りの住宅の桁側面に増築すると、増築後では、増築前と比べて、棟高さが高くなったり、棟方向が変わったりして、小屋組架構全体が変わることが多い（図１参照）。
【０００３】
このような場合には、新しい小屋組に対応させて、小屋組中央の垂直部材の頂部に新しい隅木梁を設ける必要が生じる。このため、従来は、既存の小屋組を解体して、新しい小屋組に施工し直していた。
【０００４】
【発明が解決しようとする課題】
しかしながら、既存の小屋組を全面的に解体して、新しい小屋組に施工し直すので、多くの時間と労力を要し、施工期間が長くなるだけでなく、作業性が悪いという問題点があった。
【０００５】
また、小屋組の各鋼製部材が鋼等の金属からなる場合には、小屋組の中央の垂直部材の頂部に、溶接により新規の隅木梁を設けることは可能ではあるが、垂直部材の頂部と新規の隅木梁との接合を溶接により行うために、作業性が悪いだけでなく、顧客が既存の住宅内で従来通り生活を営むことを考慮すると、十分な安全性を確保することは困難であるという問題点があった。
【０００６】
更に、既存の小屋組を全面解体することにより、多量の産業廃棄物が発生し、これを運搬、処理するために、費用がかかるという問題点があった。
【０００７】
更にまた、前述のように、多くの場合は、増築工事中であっても、顧客が既存の住宅内で生活を営むため、短期間で増築工事を終了することが望ましいが、施工期間が長くなるにしたがって、顧客に不便を強いる期間が長くなり、顧客の負担が大きくなるという問題点があった。
【０００８】
本発明は、上記課題に鑑みてなされたものであり、隅木を支持する隅木梁を有する屋根造りの住宅の桁側面に増築する際の屋根工事において、大棟中間部の垂直部材に新規の隅木梁の設置を容易に行うことができる隅木梁の設置工法を提供することを目的とする。

【００１３】
【発明の実施の形態】
以下、本発明に係る隅木梁の設置工法について図面に基づいて説明する。本発明の第１の実施形態に係る隅木梁の設置工法は、図１に示すように、寄棟造りの小屋組１がトラス小屋組である場合に、大棟２の中間部に、既存の隅木梁３の立上り角度と略等しい角度で、新規の隅木梁４を設けるものであって、図２に示すように、大棟２の中間部下の垂直部材である真束５の頂部６及び該頂部６近傍に設置された母屋受け７に、隅木梁設置金具８を用いて、新規の隅木梁４を設置することにより行うものである。以下、更に詳細に説明する。
【００１４】
既存の隅木梁３は、図３に示すように、２本のＣ型鋼９を、その開口部が外側を向くように、締結具により締結したものであって、大棟２の端部から軒先１０の出隅に向って４５°の方向に持ち出すように設けられる（図１参照）ことにより定まる立上り角度αで、真束５と所定の金具１１を介して接続している。
【００１５】
また、新規の隅木梁４は、図４に示すように、図３に示す既存の隅木梁３と同様の構成であって、その端部に、隅木梁設置金具８と接続するための貫通孔１２を穿設している。
【００１６】
真束５は、図２に示すように、図３に示す既存の隅木梁３と同様の構成であって、その頂部６には、該頂部６から斜め下方に伸びる登り梁１３を接続するために、２本のＣ型鋼９の上端を覆う頂部金具１４が設けられている。そして、図５に示すように、該頂部金具１４の蓋部１５には、登り梁１３と直交する方向に２個の貫通孔１６が穿設されている。
【００１７】
母屋受け７は、図２に示すように、母屋１７を受けるための断面略Ｌ字形の金具で、頂部金具１４の両端部に固定されたものであり、母屋１７を受ける受け部１８には、締結具を用いて母屋１７を母屋受け７に固定するための貫通孔１９が穿設されている。
【００１８】
隅木梁設置金具８は、図４に示すように、図２に示す真束５の頂部６に水平に設置される略長方形の平部２０と、該平部２０の一縁辺から略直角上向きに立ち上がる立上り部２１と、該立上り部２１の平部２０の裏側面から既存の隅木梁３の立上り角度α（図４参照）と略等しい角度で立ち上がる隅木梁接続部２２と、平部２０の一縁辺と略直交する縁辺から上向きに立ち上がる母屋受け接続部２３とを有するものである。
【００１９】
平部２０は、図４に示すように、隅木梁接続部２２と略対角の隅角部に貫通孔２４が穿設されており、該貫通孔２４から母屋受け接続部２３までの長さは、貫通孔２４と頂部金具１４の貫通孔１６とを略一致させたときに母屋受け接続部２３が母屋受け７の受け部１８（図２参照）にあてがわれる長さとする。
【００２０】
立上り部２１は、前述のように、平部２０の一縁辺から略直角上向きに立ち上がり、平部２０側面に母屋受け接続部２３の縁辺を固着させて、隅木梁設置金具８の補強を図っている。
【００２１】
隅木梁接続部２２は、前述のように、図３に示す既存の隅木梁３の立上り角度αと略等しい角度で立ち上がるように、特に平面視では、図５に示すように、立上り部２１と略１３５°の角度をなすように、立上り部２１の平部２０の裏側面の母屋受け接続部２３の方に固着される。そして、同図に示すように、貫通孔２５は、隅木梁接続部２２を新規の隅木梁４に接続した状態で頂部金具１４の蓋部１５に平部２０を設置したときに、新規の隅木梁４の長軸線Ｌが棟方向から４５°の方向に位置するように穿設される。これにより、平部２０を真束５の頂部６に取り付けると、隅木梁接続部２２が棟方向に対して４５°の軸線上に位置することとなる（図６参照）。
【００２２】
母屋受け接続部２３は、前述のように、平部２０を真束５の頂部６に設置したときに、母屋受け接続部２３が母屋受け７の受け部１８に全面密着するように（図２参照）、平部２０の一縁辺と略直交する縁辺から上向きに立ち上げて形成したものである。そして、図５に示すように、貫通孔２７は、立上り部２１と反対の端部で、平部２０の貫通孔２４と頂部金具１４の蓋部１５の貫通孔１６とを略一致させたときに母屋受け７の受け部１８の貫通孔１９と略一致する位置に穿設される。
【００２３】
次に、新規の隅木梁４の設置について説明する。まず、図４に示すように、新規の隅木梁４を構成する２本のＣ型鋼９の間に、隅木梁設置金具８の隅木梁接続部２２を、新規の隅木梁４の貫通孔１２と隅木梁接続部２２の貫通孔２５とが略一致するまで挿入し、新規の隅木梁４の貫通孔１２と隅木梁接続部２２の貫通孔２５とをボルトナットから構成される締結具２６で締結することによって、隅木梁設置金具８を新規の隅木梁４の端部に接続する。
【００２４】
なお、本実施の形態では、工事現場において新規の隅木梁４と隅木梁設置金具８の隅木梁接続部２２とをボルト締めで接続したが、これに限定されるものではなく、あらかじめ工場等において溶接により新規の隅木梁４と隅木梁設置金具８の隅木梁接続部２２とを接続しておいてもよい。
【００２５】
次に、図５に示すように、頂部金具１４の蓋部１５の貫通孔１６と隅木梁設置金具８の平部２０の貫通孔２４とが略一致するように、頂部金具１４の蓋部１５に隅木梁設置金具８の平部２０をあてがうとともに、新規の隅木梁４を設置する側の母屋受け７の受け部１８に、該受け部１８の貫通孔１９と隅木梁設置金具８の母屋受け接続部２３の貫通孔２７とが略一致するように、隅木梁設置金具８の母屋受け接続部２３をあてがい、隅木梁設置金具８を真束５の頂部６に載置する。
【００２６】
そして、頂部金具１４の蓋部１５の貫通孔１６と隅木梁設置金具８の平部２０の貫通孔２４とを締結具２６で締結することにより、隅木梁設置金具８の平部２０を頂部金具１４の蓋部１５に固定し、母屋受け７の受け部１８の貫通孔１９と隅木梁設置金具８の母屋受け接続部２３の貫通孔２７とを締結具２６で締結することにより、隅木梁設置金具８の母屋受け接続部２３を母屋受け７の受け部１８に固定する。これにより、図６に示すように、新規の隅木梁４は、真束５の頂部６に設置される。
【００２７】
このとき、、隅木梁設置金具８の隅木梁接続部２２は、隅木梁設置金具８を真束５の頂部６に固定すると、桁方向に対して略４５°の軸線上に位置し、既存の隅木梁３の立上り角度αと略等しい立上り角度で立ち上がるように、隅木梁設置金具８の立上り部２１に設けられているので、図２に示すように、隅木梁設置金具８の平部２０を頂部金具１４の蓋部１５に、隅木梁設置金具８の母屋受け接続部２３を母屋受け７の受け部１８に固定するだけで、新規の隅木梁４は図４に示す既存の隅木梁３の立上り角度αと略等しい立上り角度で真束５の頂部６に設置されることとなる。
【００２８】
以上により、新規の隅木梁４が真束５の頂部６に設置される、即ち、新規の隅木梁４が増築部側に設置される（図１参照）。
【００２９】
次に、本発明の第２の実施形態について説明する。本発明の第２の実施形態に係る隅木梁の設置工法は、小屋組が和小屋組である場合に、大棟２の中間部に、既存の隅木梁３の立上り角度と略等しい角度で、新規の隅木梁４を設けるものであって、図７に示すように、大棟２の中間部下の垂直部材である小屋束５０の頂部５１及び該頂部５１近傍に設置された母屋受け５２に、隅木梁設置金具８を用いて、新規の隅木梁４を設置することにより行うものである。以下、更に詳細に説明する。
【００３０】
小屋束５０は、第１の実施形態に示す真束５と同様の構成であり、その頂部５１に、該頂部５１から斜め下方に登り梁５３を接続するために、２本のＣ型鋼９の上端を覆う頂部金具５４が設けられている。そして、該頂部金具５４の蓋部５５には、登り梁５３と直交する方向に２個の貫通孔５６が穿設されている。
【００３１】
母屋受け５２は、頂部金具５４の蓋部５５の両端部を上方へ折り曲げて、母屋１７を受ける受け部５７を形成したものであり、該受け部５７には、締結具を用いて母屋１７を母屋受け５２に固定するための貫通孔５８が穿設されている。
【００３２】
新規の隅木梁４の取付けについては、第１の実施形態と同様であり、新規の隅木梁４の端部に隅木梁設置金具８の隅木梁接続部２２を接続し、頂部金具５４の蓋部５５の貫通孔５６と隅木梁設置金具８の平部２０の貫通孔２４とを締結具２６で締結することにより、隅木梁設置金具８の平部２０を頂部金具５４の蓋部５５に固定し、母屋受け５２の受け部５７の貫通孔５８と隅木梁設置金具８の母屋受け接続部２３の貫通孔２７とを締結具２６で締結することにより、隅木梁設置金具８の母屋受け接続部２３を母屋受け５２の受け部５７に固定することにより行われる。これにより、新規の隅木梁４は、小屋束５０の頂部５１に設けられる、即ち、増築部側へ設置されることとなる（図１参照）。
【００３３】
なお、第１の実施形態及び第２の実施形態では、各部材を２本のＣ型鋼９を締結具で締結することにより形成しているが、これに限定されるものではなく、鋼製の管体や木製の角材としてもよい。この場合には、隅木梁設置金具８の隅木梁接続部２２の形状を、例えば、図８に示すような形状として、新規の隅木梁１００を小屋組中央の真束５の頂部６又は小屋束５０の頂部５１に設置する。
【００３４】
また、第１の実施形態及び第２の実施形態では、真束５の頂部６又は小屋束５０の頂部５１に隅木梁設置金具８の平部２０を固定し、母屋受け７の受け部１８又は母屋受け５２の受け部５７に隅木梁設置金具８の母屋受け接続部２３を固定して、新規の隅木梁４を母屋受け７又は母屋受け５２に設置することとしているが、例えば、隅木梁設置金具８の形状を図９に示すような形状として、母屋受け７又は母屋受け５２のみに隅木梁設置金具８を固定して、新規の隅木梁４を母屋受け７又は母屋受け５２に設置するようにしてもよい。
