【発明の属する技術分野】
本発明は屋根棟に関する。
【０００２】
【従来の技術】
本出願人は、先に、棟冠の両端に端部棟冠を配置し、屋根面の妻端部に装着された妻部材の上端部を端部棟冠の垂下片の下方に挿入し、妻部材の外側に位置する端部棟冠の端部側壁の裏面に摺動可能に重合される防水調整板を内側に移動させて、その内側端縁を妻部材の外側円に当接し、この位置で防水調整板を固定して、妻部材と端部棟冠の端部側壁との間隙を塞ぐ技術を特開昭６３−２２６４４６号として提案した。
【０００３】
しかし、このものは、幅の狭い端部側壁に防水調整板が重合されているので、防水調整板の移動可能幅が小さくて上記間隙を完全に被覆することができない虞があるばかりか、幅狭い端部側壁に防水調整板を案内する長孔を穿設すると、この部分の強度が非常に弱くなってしまい、この結果、強風時に端部側壁が破損する心配がある。
【０００４】
さらに、上記従来の屋根棟では、端部棟冠と棟冠との接続部を覆う連結カバー材にパッキングが装着されていないので、防水性が十分でない。また、端部棟冠に穿設された長孔に連結カバー材の裏面に植設されたボルトを挿入し、該ボルトを長孔の適宜位置で固定することにより、連結カバー材を固定するので、連結カバー材の下方からボルトにナットを螺合しなければならず、このため、野地板を敷設する屋根では非常に操作性が悪いものである。
【０００５】
【発明が解決しようとする課題】
本発明は、棟端部部材とケラバ部材との隙間からの漏水を防止することができ、棟の長さ及びケラバ部材の幅の誤差を吸収することが可能で、体裁が良く施工が容易な屋根棟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】
本発明の屋根棟は、上記課題を達成するために、棟部材の両端に棟端部部材を装着し、該棟端部部材の両側の側面の妻寄りに嵌合切欠を形成し、ケラバ部材の棟寄り端部を前記嵌合切欠に挿入して成る屋根棟において、前記棟端部部材の側壁の裏面に棟線と平行な摺動溝を形成し、前記側壁の裏面に重合される短尺の防水材を前記摺動溝に摺動可能に嵌合し、該防水材の妻寄り端縁を前記ケラバ部材の内側の側面に当接して固定する。
嵌合切欠の外側端縁をケラバ部材の外側面に当接して棟端部部材を配置し、防水材を妻方向に移動してその外側端縁がケラバ部材に当接した位置で防水材を固定し、ケラバ部材と嵌合切欠との隙間を塞ぐ。
【０００７】
棟端部部材及び棟部材の表面に、該棟端部部材と棟部材との接続部を被覆する連結カバーを摺動可能に嵌装し、該連結カバーの裏面にパッキングを装着し、前記棟端部部材の前記接続部寄りの頂部に棟線に沿って長孔を穿設し、前記連結カバーに取付けられた固定具を該長孔に摺動固定自在に挿通し、該固定具によって連結カバーを固定することは望ましい。
連結カバーによって棟端部部材と棟部材との接続部に形成される隙間を塞ぎ、パッキングが該接続部に流入しようとする雨水を遮断する。
【０００８】
また、固定具が連結カバーを貫通するボルトより成り、前記連結カバーまたは棟部材の頂部下面に棟線と平行なガイド溝を形成すると共に、該ガイド溝の上底部に前記長孔を穿設し、前記ガイド溝に回り止め部材を摺動可能に装着すると共に、該回り止め部材に前記固定具と螺合される雌ネジ孔を形成することは望ましい。
ボルトの位置が決まった段階で棟の上方からボルトを回動し、回転が抑制された回り止め部材の雌ネジ孔に螺合して締め付けることにより、連結カバーを固定する。
【０００９】
【発明の実施の形態】
図３は、本発明の屋根棟に係る段葺き屋根の全体図である。
切妻屋根の屋根下地上に、横に長い屋根板１が前後左右に多数枚並設されて固定され、前後方向（勾配方向）に隣接する屋根板１の前後端部が互いに係合されると共に、左右に隣接する屋根板１の側端部上面間にキャップ２が架設されて各屋根板１どうしが連結されている。
【００１０】
また、屋根の最も側端部に位置する屋根板１の外側端は妻面に沿って配設されたケラバ部材３の内側部に係合され、屋根棟に沿って棟部材４が配設される。 棟部材４は長手方向に複数に分割されると共に、棟連結部材５を介して連結されている。また、棟部材４の両端に棟端部部材６が装着され、棟部材４と棟端部部材６との接続部は連結カバー７で被覆されている。
なお、図を簡略化するために、屋根板は横２列に敷設されているが、屋根幅及び屋根板１の長さによって３列以上並設する場合もある。
【００１１】
図６に示すように、棟部材４は上方凸に湾曲する冠部８を有し、その下面両側から側壁９が垂下されると共に、側壁９の外方において冠部８の両端に係合屈曲部１０が下方に向いて形成されている。また、側壁９の下端部内面から内方に水平に張り出し、その先端を下方に屈曲して支脚１１が形成される。さらに、冠部８の下面の幅方向中央部にボルト固定溝１２が長手方向に沿って設けられる。また、冠部８の長手方向両端部においてボルト固定溝１２の上方にナット操作用切欠３７´が形成されている。
【００１２】
この棟部材４は、図５に示すように、左右屋根面の最上段に配置される屋根板１，１間に架設され、その支脚１１が屋根板１の上面に載置される。また、屋根下地に取付けられた固定ボルト１３の上端がボルト固定溝１２内に挿入され、ナット操作用切欠３７´を通して、ボルト固定溝１２内の固定ボルト１３の上端に抜け止め座金１４を介してナット３７が螺合され、これにより、棟部材４が屋根下地に固定される。
【００１３】
棟連結部材５は、図７に示すように、棟部材４の外面に沿う形状を成しており、その両側下端に棟部材４の側壁９下端に摺動可能に係合する棟部材係合部１５が形成され、該棟部材係合部１５の上方に棟部材４の係合屈曲部１０に摺動可能に係合する摺動係止部１６が形成されている。
また、棟連結部材５の天部裏面に断面波状の下面を有するパッキング１７が重合され、図５に示すように、このパッキング１７が棟部材４の冠部８との間に介在されるようになっている。このため、棟連結部材５と棟部材４との隙間から雨水が侵入することがない。
【００１４】
棟部材４を長手方向に連結するには、図８に示すように、先に配置した棟部材４の端部から棟連結部材５を嵌め込み、棟部材４の側壁９下端及び係合屈曲部１０に棟連結部材５の棟部材係合部１５及び摺動係止部１６を係止して、棟部材４の外面に棟連結部材５を被せておく。
次に、先に配置した棟部材４に隣接してその延長上に他の棟部材４を配置した後、棟連結部材５を矢印ｃ方向に摺動して隣接する２本の棟部材４，４の接続端部及びナット操作用切欠３７´を被覆し、棟部材４に対して雨仕舞構造を構成する。
【００１５】
そして、屋根板１の勾配方向の長さの合計と屋根下地の長さとの間に誤差がある場合は、最上段の屋根板１とその表面に架設される棟部材４との重合幅を変えることによって、上記誤差を吸収するようになっている。
すなわち、屋根板１の長さの合計が屋根下地の長さに対して短い場合は、図９の（イ）に示すように、屋根板１の後端部が棟部材４の外側下部に形成された支脚１１に近づき、この位置で固定されてマイナス調節取付となる。
【００１６】
また、屋根板１の長さの合計が屋根下地の長さに対して基準通りであり、棟部分における調節が不要の場合は、図９の（ロ）に示すように、棟部材４の下方において、その片側の中央位置に屋根板１の後端部が位置して固定され、標準取付となる。
屋根板１の長さの合計が屋根下地の長さに対して長い場合は、図９の（ハ）に示すように、屋根板１の後端部が棟部材４の下方において屋根頂部に接近し、この位置で固定されてプラス調節取付となる。
【００１７】
図１０及び図３に示すように、棟部材４の両端に装着される棟端部部材６は、棟部材４とほぼ同様の断面を有する。すなわち、棟部材４に対応する冠部８´、側壁９´、係合屈曲部１０´、支脚１１´を備える。
また、棟端部部材６の妻寄り端面は側壁９´より下方に延びる端部壁１８で閉塞されており、端部壁１８の内側端部から側壁９´の妻寄り端部にかけて嵌合切欠１９が形成されている。この嵌合切欠１９には、図４に示すように、ケラバ部材３の棟寄り端部が挿入され、端部壁１８の嵌合切欠１９より下方の部分がケラバ部材３の下面に係止されるようになっている。
【００１８】
さらに、棟端部部材６の冠部８´の中央下面に、棟部材４のボルト固定溝１２とほぼ同形のガイド溝２０が棟線と平行に形成される。該ガイド溝２０の開口部は奥部より幅狭く形成され、その上底部の中央部に取り付け孔２１が、棟部材４寄りに長孔２２がそれぞれ穿設される。この長孔２２は、長軸が棟線と一致するように形成されている。
そして、図１３に示すように、ガイド溝２０にこれよりやや巾が狭い四角形の回り止め部材２３が、摺動自在に且つ回動不能に嵌合され、該回り止め部材２３には雌ネジ孔２４が穿設されている。
【００１９】
また、棟端部部材６の両側側壁９´の裏面に、棟部材４寄りの端縁から嵌合切欠１９に亘って棟線と平行な摺動溝２５が形成される。摺動溝２５の開口部は奥部より幅狭く形成され、その下端に支脚１１´が設けられる。また、摺動溝２５の底部において側壁９´の嵌合切欠１９寄りに、棟線に沿って長い摺動孔２６が穿設されている。
【００２０】
この摺動溝２５に短尺の防水材２７が摺動可能に装着される。防水材２７は、摺動溝２６に係合されて側壁９´の裏面に重合される係止板２８と、係止板２８の裏面から突設されて支脚１１´の裏面に重合される防水壁２９とを備える。 係止板２８にはネジ孔３０が穿設され、摺動孔２６に挿通された化粧ボルト３８の先端がこのネジ孔３０に螺合される。従って、防水材２７は、側壁９´の妻寄り端部において摺動孔２６の長さだけ摺動することができるようになっている。なお、防水材２７の妻寄り端縁はケラバ部材３の内側面に合致するよう切欠かれ、嵌合切欠１９の内側部に突出されている。
【００２１】
連結カバー７は、棟端部部材６の棟部材４寄り端部の表面に摺動可能に嵌合され、棟部材４及び棟端部部材６の冠部８，８´を覆う冠部被覆部３１と側壁９，９´を覆う側壁被覆部３２を備える。そして、側壁被覆部３２の上端が棟端部部材６の係合屈曲部１０´に係合されると共に、側壁被覆部３２の下端が支脚１１´に係合され、連結カバー７がスムーズに案内されるようになっている。
【００２２】
また、連結カバー７の冠部被覆部３１の棟部材４寄り端部は他の部分よりやや上方に膨隆されて被覆蓋部３３が形成され、図１１に示すように、この被覆蓋部３３の裏面にパッキング１７´が装着されている。パッキング１７´は、図１２に示すように、各山部及び谷部が棟線に交差して延びる波形の断面を有し、パッキング１７´の下面が棟部材４及び棟端部部材６の表面に密着した時に、その波形の形状によって形成される多数の平行な狭小空間が表面張力に基づく毛細管現象による雨水の侵入を遮断するようになっている。
【００２３】
さらに、冠部被覆部３１の頂部の妻寄りにボルト挿通孔３４が穿設されている。図１３に示すように、ボルト挿通孔３４の上方からボルト３５が挿通され、ボルト３５の先端が長孔２２を介して棟端部部材６を貫通し、回り止め部材２３の雌ネジ孔２４に螺合されている。
【００２４】
棟部材４と棟端部部材６とは次のように接続される。
棟部材４を装着した後、図２に示すように、その両端に棟端部部材６を配置し、ケラバ部材３の棟寄り端部を棟端部部材６の嵌合切欠１９に挿入する。この時、嵌合切欠１９の外方側縁がケラバ部材６の外側面に当接される。なお、棟の長さによって、棟部材４と棟端部部材６との接続部の間隙幅が多少変化する。
この位置に配置された棟端部部材６の取り付け孔２１に化粧釘３６を打ち込んで、棟端部部材６を屋根下地に固定する。
【００２５】
次に、化粧ボルト３８を摺動孔２６に沿って矢印ｂ方向に動かすことにより、防水材２７を妻方向に移動してその妻寄り端縁をケラバ部材３の内側面に当接し、嵌合切欠１９とケラバ部材３との隙間を塞ぐ。この位置で化粧ボルト３８を締め付けて防水材２７を固定する。
【００２６】
次いで、連結カバー７を矢印ｃに沿って棟部材４の方向に移動し、図１に示すように、被覆蓋部３３及び側壁被覆部３２で棟部材４と棟端部部材６との接続部表面を覆う。すると、連結カバー７を貫通するボルト３５は長孔２２に沿って移動するので、連結カバー７の位置が決定されたら、棟の上方からボルト３５を締め付けて連結カバー７を固定する。
【００２７】
上記実施形態においては、棟端部部材６が化粧釘３６で強固に屋根下地に固定されると共に、棟部材４が固定ボルト１３で固定され、しかも、連結カバー７の側壁被覆部３２の上下端が棟部材４及び棟端部部材６の係合屈曲部１０，１０´及び支脚１１，１１´に係合されるので、風に対する耐久性が非常に大きく、台風等による強風時にも屋根棟が破損する事がない。
また、連結カバー７は棟部材４に対して摺動可能に被覆されているので、温度変化によって棟部材４及び棟端部部材６が多少伸縮し、これらの接続部の間隙幅が増減しても、この増減を吸収することができる。
【００２８】
さらに、連結カバー７が棟部材４と棟端部部材６との接続部の表面を覆って雨水の侵入を防ぐと共に、波形のパッキング１７´によって棟部材４及び棟端部部材６の表面との間に形成される狭小空間が、表面張力に基づく毛細管現象による雨水の侵入を遮断するので、高度な防水性能が得られる。
また、防水材２７が摺動してケラバ部材３の内側面に当接されると共に、防水材２７の妻寄り端縁がケラバ部材３の内側面に合致する形状に形成されているので、ケラバ部材３と嵌合切欠１９との隙間が塞がれて更に防水性が増すと共に外観も美しくなり、ケラバ部材３と嵌合切欠１９の幅に誤差があっても、防水材２７が摺動してこの誤差を吸収することができる。
【００２９】
【発明の効果】
請求項１の構成によれば、ケラバ部材と嵌合切欠との隙間が防水材によって完全に塞がれるので、この部分から雨水が吹き込む虞が無く、防水性が増すばかりか、体裁が良い。
また、ケラバ部材と嵌合切欠の幅に誤差があっても、防水材が摺動してケラバ部材に当接するので、上記誤差を吸収することができる。
【００３０】
さらに、防水材は、棟端部部材の棟部材寄りの側壁に摺動自在に重合されているので、幅狭い妻側の側壁に設けられたものと比較して摺動可能幅を十分にとることができ、このため、ケラバ部材と嵌合切欠との幅の誤差が大きくてもこれに追随することが可能であり、防水材をガイドする摺動孔によって棟端部部材の側壁の強度が著しく低下する心配もない。
【００３１】
請求項２の構成によれば、棟端部部材に予め連結カバーを取付けておき、棟端部部材を棟部材の外側に配置した後連連結カバーを移動するだけで、棟端部部材と棟部材との接続部を被覆することができるので施工が簡単であり、ケラバ部材と棟端部部材との係合及び棟端部部材と棟部材に対する連結カバーの嵌合が相俟って、風圧及び振動に対する耐久性が増大し、強靭となる。
また、棟部材と棟端部部材との間隙幅を適宜変更して棟の長さに対応することが可能であり、接続部における間隙幅が多少変化してもその上面が連結カバーで覆われるので、外観には現れず体裁が良い。
さらに、このように連結カバーで上記接続部の隙間を覆うと共に、パッキングで雨水の侵入を遮断するため、防水性能がきわめて良好である。
【００３２】
請求項３の構成によれば、ボルトを長孔に沿って摺動させた後、棟の上方から締め付けるだけで連結カバーを固定することができ、棟の下方における作業が不要であるため、施工性がきわめて良い。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a roof ridge.
[0002]
[Prior art]
The applicant has previously arranged end crowns at both ends of the crown, and inserted the upper end of the wife member attached to the wife end of the roof surface below the hanging piece of the end crown, The waterproof adjustment plate slidably superimposed on the back surface of the end side wall of the end crown located outside the wife member is moved inward, and its inner edge abuts on the outer circle of the wife member. Japanese Patent Application Laid-Open No. Sho 63-226446 proposes a technique in which a waterproof adjustment plate is fixed at a position to close the gap between the end member and the end side wall of the end cap.
[0003]
However, in this case, since the waterproof adjustment plate is overlapped on the narrow end side wall, not only the movable width of the waterproof adjustment plate is so small that the gap cannot be completely covered, If a long hole for guiding the waterproof adjustment plate is formed in the narrow end side wall, the strength of this portion becomes very weak, and as a result, there is a concern that the end side wall may be damaged in a strong wind.
[0004]
Furthermore, in the above-mentioned conventional roof ridge, since the packing is not attached to the connecting cover material that covers the connection between the end ridge crown and the ridge crown, the waterproof property is not sufficient. Also, since the bolts planted on the back surface of the connecting cover material are inserted into the long holes formed in the end cap, and the bolts are fixed at appropriate positions in the long holes, the connecting cover material is fixed. In addition, the nut must be screwed into the bolt from below the connecting cover material, and therefore, the operability of the roof on which the base plate is laid is extremely poor.
[0005]
[Problems to be solved by the invention]
The present invention can prevent water leakage from the gap between the ridge end member and the keraba member, can absorb errors in the length of the ridge and the width of the keraba member, and has a good appearance and easy construction. The purpose is to provide a roof ridge.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a roof ridge according to the present invention has ridge end members attached to both ends of the ridge member, and a fitting notch is formed at a wedge on both sides of the ridge end member. In the roof ridge formed by inserting the ridge-side end into the fitting notch, a sliding groove parallel to the ridge line is formed on the back surface of the side wall of the ridge end member, and the short length is superimposed on the back surface of the side wall. Of the waterproof material is slidably fitted in the sliding groove, and the edge of the waterproof material near the end is abutted on the inner side surface of the keraba member and fixed.
The ridge end member is arranged by abutting the outer edge of the fitting notch on the outer surface of the keraba member, and the waterproof material is moved in the direction of the wife, and the waterproof material is placed at a position where the outer edge abuts the keraba member. Fix and close the gap between the keraba member and the fitting cutout.
[0007]
A ridge end member and a connection cover for covering a connection portion between the ridge end member and the ridge member are slidably fitted on the surface of the ridge member, and packing is mounted on a back surface of the connection cover, A long hole is formed along the ridge line at the top of the end member near the connection portion, and a fixing device attached to the connection cover is slidably fixed through the long hole and connected by the fixing device. It is desirable to secure the cover.
The connection cover closes the gap formed at the connection between the ridge end member and the ridge member, and the packing blocks rainwater from flowing into the connection.
[0008]
Further, the fixing tool is composed of a bolt penetrating the connection cover, and a guide groove parallel to the ridge line is formed on the lower surface of the top of the connection cover or the ridge member, and the long hole is formed in the upper bottom of the guide groove. It is preferable that a detent member is slidably mounted in the guide groove, and that the detent member is formed with a female screw hole screwed with the fixing tool.
When the bolt position is determined, the connection cover is fixed by rotating the bolt from above the ridge and screwing it into the female screw hole of the rotation preventing member whose rotation has been suppressed.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 3 is an overall view of a stepped roof according to the roof building of the present invention.
A large number of laterally long shingles 1 are fixed side by side on the roof foundation of the gable roof, and the front and rear ends of the shingles 1 adjacent to each other in the front and rear direction (gradient direction) are engaged with each other. A cap 2 is erected between the upper surfaces of the side edges of the roof shingles 1 adjacent to each other on the left and right sides, and the roof shingles 1 are connected to each other.

Further, the outer edge of the shingle 1 located at the side edge of the roof is engaged with the inner portion of the keraba member 3 arranged along the wife surface, and the ridge member 4 is arranged along the roof ridge. You. The ridge member 4 is divided into a plurality in the longitudinal direction, and is connected via a ridge connection member 5. Further, ridge end members 6 are attached to both ends of the ridge member 4, and a connection portion between the ridge member 4 and the ridge end member 6 is covered with a connection cover 7.
In order to simplify the drawing, the shingles are laid in two horizontal rows, but three or more shingles may be juxtaposed depending on the roof width and the length of the shingle 1.
[0011]
As shown in FIG. 6, the ridge member 4 has a crown portion 8 that curves upwardly convex, and the side walls 9 hang down from both lower surfaces thereof, and engage and bend with both ends of the crown portion 8 outside the side wall 9. The part 10 is formed facing downward. Further, the support leg 11 is formed by horizontally projecting inward from the inner surface of the lower end portion of the side wall 9 and bending the tip thereof downward. Further, a bolt fixing groove 12 is provided along the longitudinal direction at the center of the lower surface of the crown portion 8 in the width direction. In addition, nut operating notches 37 ′ are formed above the bolt fixing grooves 12 at both ends in the longitudinal direction of the crown 8.

As shown in FIG. 5, the ridge member 4 is installed between the roof shingles 1 and 1 arranged at the uppermost stage of the left and right roof surfaces, and its supporting legs 11 are placed on the upper surface of the roof shingle 1. Further, the upper end of the fixing bolt 13 attached to the roof foundation is inserted into the bolt fixing groove 12, passes through the nut operating notch 37 ′, and through the retaining washer 14 to the upper end of the fixing bolt 13 in the bolt fixing groove 12. The nut 37 is screwed, whereby the ridge member 4 is fixed to the roof foundation.
[0013]
As shown in FIG. 7, the ridge connecting member 5 has a shape along the outer surface of the ridge member 4, and ridge member engagement slidably engaged with the lower end of the side wall 9 of the ridge member 4 at both lower ends thereof. A portion 15 is formed, and a sliding locking portion 16 is formed above the ridge member engaging portion 15 so as to slidably engage with the engaging bent portion 10 of the ridge member 4.
In addition, a packing 17 having a wavy cross-section lower surface is superimposed on the top back surface of the ridge connection member 5 so that the packing 17 is interposed between the ridge member 4 and the crown portion 8 as shown in FIG. Has become. Therefore, rainwater does not enter through the gap between the ridge connection member 5 and the ridge member 4.
[0014]
In order to connect the ridge members 4 in the longitudinal direction, as shown in FIG. 8, the ridge connection member 5 is fitted from the end of the ridge member 4 arranged first, and the lower end of the side wall 9 and the engagement bending portion 10 of the ridge member 4 are fitted. The ridge member engaging portion 15 and the sliding locking portion 16 of the ridge connection member 5 are locked on the ridge connection member 5, and the ridge connection member 5 is put on the outer surface of the ridge member 4.
Next, after arranging another ridge member 4 on its extension adjacent to the ridge member 4 previously arranged, the ridge connection member 5 is slid in the direction of arrow c to form two adjacent ridge members 4, 4 to cover the connection end and the notch 37 ′ for the nut operation, and constitute a rain closing structure for the ridge member 4.
[0015]
If there is an error between the total length of the roof shingle 1 in the gradient direction and the length of the roof foundation, the overlapping width between the top shingle 1 and the ridge member 4 installed on the surface is changed. This absorbs the error.
In other words, when the total length of the roof shingle 1 is shorter than the length of the roof foundation, the rear end of the roof shingle 1 is formed on the lower outside of the ridge member 4 as shown in FIG. Approaching the support leg 11 that has been fixed, and is fixed at this position to perform minus adjustment mounting.
[0016]
When the total length of the shingle 1 is the same as the length of the roof base and the adjustment at the ridge portion is unnecessary, as shown in FIG. In the above, the rear end of the shingle 1 is positioned and fixed at the center position on one side, and standard installation is performed.
If the total length of the shingle 1 is longer than the length of the roof foundation, the rear end of the shingle 1 approaches the roof top below the ridge member 4 as shown in FIG. Then, it is fixed at this position to make a plus adjustment mounting.
[0017]
As shown in FIGS. 10 and 3, the ridge end members 6 attached to both ends of the ridge member 4 have substantially the same cross section as the ridge member 4. That is, a crown portion 8 ', a side wall 9', an engagement bending portion 10 ', and a support leg 11' corresponding to the ridge member 4 are provided.
Further, the end face of the ridge end member 6 near the wedge is closed by an end wall 18 extending below the side wall 9 ′, and a notch is fitted from the inner end of the end wall 18 to the wedge end of the side wall 9 ′. 19 are formed. As shown in FIG. 4, the ridge-side end portion of the keraba member 3 is inserted into the fitting notch 19, and a portion of the end wall 18 below the fitting notch 19 is engaged with the lower surface of the kerava member 3. It has become so.

Further, a guide groove 20 having substantially the same shape as the bolt fixing groove 12 of the ridge member 4 is formed on the central lower surface of the crown 8 ′ of the ridge end member 6 in parallel with the ridge line. The opening of the guide groove 20 is formed to be narrower than the inner part, and a mounting hole 21 is formed in the center of the upper bottom, and a long hole 22 is formed near the ridge member 4. The long hole 22 is formed such that the long axis coincides with the ridge line.
As shown in FIG. 13, a rectangular locking member 23 having a slightly smaller width is fitted into the guide groove 20 so as to be slidable and non-rotatable. 24 are drilled.
[0019]
In addition, a sliding groove 25 is formed on the back surface of both side walls 9 ′ of the ridge end member 6 from the edge near the ridge member 4 to the fitting notch 19 and parallel to the ridge line. The opening of the sliding groove 25 is formed to be narrower than the inner part, and a supporting leg 11 'is provided at the lower end thereof. A long sliding hole 26 is formed along the ridgeline near the fitting notch 19 of the side wall 9 ′ at the bottom of the sliding groove 25.
[0020]
A short waterproof material 27 is slidably mounted in the sliding groove 25. The waterproof member 27 is engaged with the sliding groove 26 and overlaps the back surface of the side wall 9 ′, and the waterproof member protrudes from the back surface of the lock plate 28 and overlaps the back surface of the support leg 11 ′. And a wall 29. A screw hole 30 is formed in the locking plate 28, and a tip of a decorative bolt 38 inserted into the sliding hole 26 is screwed into the screw hole 30. Therefore, the waterproof member 27 can slide by the length of the sliding hole 26 at the end of the side wall 9 ′ near the end. The edge of the waterproof material 27 near the wife is cut out so as to coincide with the inner surface of the fluffy member 3 and protrudes inside the fitting notch 19.
[0021]
The connecting cover 7 is slidably fitted to the surface of the ridge member 4 near the ridge member 4 of the ridge end member 6, and covers a crown portion 8, 8 ′ of the ridge member 4 and the ridge end member 6. 31 and a side wall covering portion 32 that covers the side walls 9, 9 '. Then, the upper end of the side wall covering portion 32 is engaged with the engaging bent portion 10 'of the ridge end member 6, and the lower end of the side wall covering portion 32 is engaged with the support leg 11', so that the connection cover 7 is smoothly guided. It is supposed to be.
[0022]
Further, the end of the crown cover 31 of the connection cover 7 near the ridge member 4 is bulged slightly above other portions to form a cover lid 33, and as shown in FIG. A packing 17 'is mounted on the back surface. As shown in FIG. 12, the packing 17 ′ has a corrugated cross section in which each peak and valley crosses a ridge line, and the lower surface of the packing 17 ′ is the surface of the ridge member 4 and the ridge end member 6. When it comes into close contact with the surface, a large number of parallel narrow spaces formed by the shape of the waveform block rainwater from entering due to capillary action based on surface tension.
[0023]
Further, a bolt insertion hole 34 is formed near the wife at the top of the crown covering portion 31. As shown in FIG. 13, a bolt 35 is inserted from above the bolt insertion hole 34, and the tip of the bolt 35 penetrates the ridge end member 6 through the elongated hole 22, and is inserted into the female screw hole 24 of the detent member 23. It is screwed.
[0024]
The ridge member 4 and the ridge end member 6 are connected as follows.
After the ridge member 4 is mounted, the ridge end members 6 are disposed at both ends thereof as shown in FIG. 2, and the ridge-side end of the keraba member 3 is inserted into the fitting notch 19 of the ridge end member 6. At this time, the outer side edge of the fitting notch 19 is in contact with the outer side surface of the fluffy member 6. Note that the width of the gap at the connection between the ridge member 4 and the ridge end member 6 slightly changes depending on the length of the ridge.
A nail 36 is driven into the mounting hole 21 of the ridge end member 6 arranged at this position, and the ridge end member 6 is fixed to the roof foundation.
[0025]
Next, by moving the decorative bolt 38 in the direction of arrow b along the sliding hole 26, the waterproof material 27 is moved in the direction of the wife, and the edge near the wife is brought into contact with the inner surface of the keraba member 3 and fitted. The gap between the notch 19 and the keraba member 3 is closed. At this position, the waterproof bolt 27 is fixed by tightening the decorative bolt 38.
[0026]
Next, the connecting cover 7 is moved in the direction of the ridge member 4 along the arrow c, and as shown in FIG. 1, the connecting portion between the ridge member 4 and the ridge end member 6 is formed by the covering lid portion 33 and the side wall covering portion 32. Cover the surface. Then, the bolt 35 penetrating through the connection cover 7 moves along the elongated hole 22, and when the position of the connection cover 7 is determined, the bolt 35 is tightened from above the ridge to fix the connection cover 7.
[0027]
In the above embodiment, the ridge end member 6 is firmly fixed to the roof foundation with the decorative nail 36, the ridge member 4 is fixed with the fixing bolts 13, and the upper and lower ends of the side wall covering portion 32 of the connection cover 7 Is engaged with the engaging bent portions 10 and 10 'of the ridge member 4 and the ridge end member 6, and the supporting legs 11 and 11'. There is no damage.
Further, since the connection cover 7 is slidably covered with respect to the ridge member 4, the ridge member 4 and the ridge end member 6 slightly expand and contract due to a temperature change, and the gap width between these connection portions increases and decreases. Can also absorb this increase or decrease.
[0028]
Further, the connecting cover 7 covers the surface of the connecting portion between the ridge member 4 and the ridge end member 6 to prevent rainwater from entering, and the corrugated packing 17 ′ forms a connection between the ridge member 4 and the ridge end member 6. Since the narrow space formed therebetween blocks rainwater intrusion due to capillary action based on surface tension, high waterproof performance can be obtained.
Further, since the waterproof member 27 slides and abuts on the inner surface of the keraba member 3, and the edge of the waterproof member 27 near the end of the waterproof member 27 is formed in a shape matching the inner surface of the keraba member 3. The gap between the member 3 and the fitting notch 19 is closed to further increase the waterproofness and enhance the appearance, and even if there is an error in the width between the keraba member 3 and the fitting notch 19, the waterproof material 27 slides. Leverage errors can be absorbed.
[0029]
【The invention's effect】
According to the configuration of the first aspect, the gap between the keraba member and the fitting cutout is completely closed by the waterproof material, so that there is no possibility of rainwater blowing from this portion, and not only the waterproofness is increased, but also the appearance is good.
Further, even if there is an error in the width of the fitting notch with the kerava member, the above error can be absorbed because the waterproof material slides and comes into contact with the kerava member.
[0030]
Furthermore, since the waterproof material is slidably overlapped on the side wall of the ridge end member near the ridge member, the slidable width is sufficiently larger than that provided on the narrow side wall on the wife side. For this reason, even if there is a large error in the width between the keraba member and the fitting notch, it is possible to follow the error, and the sliding hole for guiding the waterproof material reduces the strength of the side wall of the ridge end member. There is no fear of significant decline.
[0031]
According to the configuration of claim 2, the ridge end member is attached to the ridge end member in advance, and the ridge end member is arranged outside the ridge member. Since the connection with the member can be covered, the construction is simple, and the engagement between the keraba member and the ridge end member and the fitting of the connection cover to the ridge end member and the ridge member are combined, so that the wind pressure is reduced. In addition, the durability against vibrations increases, and the toughness increases.
In addition, it is possible to appropriately change the gap width between the ridge member and the ridge end member to correspond to the length of the ridge, and even if the gap width at the connection portion is slightly changed, the upper surface thereof is covered with the connection cover. So it doesn't show up in appearance and looks good.
Furthermore, since the connection cover covers the gap between the connection portions and the packing prevents rainwater from entering, the waterproof performance is extremely good.
[0032]
According to the configuration of the third aspect, after the bolt is slid along the long hole, the connection cover can be fixed only by tightening from the upper part of the ridge, and the work under the ridge is unnecessary. Very good nature.
