【発明の属する技術分野】
本発明は、和風瓦葺きの大棟や陸棟、落棟、隅棟などの瓦（以下、棟瓦という）の棟瓦固定バンドに関し、詳しくは棟瓦固定バンドを使用して垂木や野地板や専用下地材などに螺着することにより、のし瓦や冠瓦を安定・強固にした地震や強風の防災対策のための棟瓦固定バンドに関するものである。
【０００２】
【従来の技術】
従来、和風建築の瓦葺き工事における棟部の構造は、複数段の積のし瓦と冠瓦を全体に銅線で緊結させた千鳥格子施工や、野地板や垂木に打ち込まれたフック状の釘に銅線を掛止し、複数段の積のし瓦の上部に設置された冠瓦に該銅線の両端を挿通して中央部で結束させた心しばり施工による方法が一般に採用されている現状である。
【０００３】
従来の構造を図４ａ、図４ｂで千鳥格子施工を、図５ａ、図５ｂで心しばり施工を説明すると、予め棟木５、垂木６、野地板７を使用して屋根１１の傾斜面を形成させ、瓦桟木１７を所定の位置に釘８で固定させて配設し、該瓦桟木１７に桟瓦４を均衡に掛止させて瓦緊結用釘９で固定されることにより棟部分が構成される。然る後に棟土１０を棟部分の桟瓦４の上に載せ、その周囲にのし瓦２、棟土１０、のし瓦２、と順次積み上げして最後に冠瓦３を載せて大棟１が完成される。
【０００４】
そこで図４ａ、図４ｂに示すように、予め緊結用の銅線１３をのし瓦施工前に大棟１の長手方向に対し千鳥状に左右方向へ渡設し、棟土１０に包含させ、更にのし瓦２と冠瓦３を載せ、棟瓦の施工が一列完成した時点で別の緊結用の銅線１２を既設の銅線１３の輪に渡し込みながら左右・千鳥格子状に編み上げるものが千鳥格子施工である。
【０００５】
また図５ａ、図５ｂに示すように、棟木５や野地板７などの屋根下地にフック状の釘１５を打設し、該釘１５に緊結用の銅線１４を掛止し、同様に棟土１０やのし瓦２を積上げて、最後に冠瓦３の天井中央部に２個の丸孔３３を穿設させ、該緊結用の銅線１４を挿通して結束することにより大棟１の固定としたものが心しばり施工である。
【０００６】
【発明が解決しようとする課題】
然し、上記の千鳥格子施工では、のし瓦と冠瓦を緊結した銅線が棟土を貫通しているだけで野地板やその他の建築物の構造に係止されていない。且つ建築年数が経ち緊結用の銅線が腐蝕・折損した場合、該銅線が連続して渡設しているため、地震や強風などで棟土が崩れ易く、のし瓦と冠瓦がずれて落下したり吹き飛ばされる課題があった。
【０００７】
更に上記の心しばり施工では、のし瓦と冠瓦の構造に於て、ほとんど棟土で固止されているので、地震や強風などの横からの力に対してフック状の釘の１点に力が作用し、一度棟瓦の構造が崩壊すると重量が係り次々と屋根が落下し易く防災には適さない課題もあった。またフック状の釘は棟木に固定されるが、離脱し易い方向に力が働き釘が抜け落ちてしまう問題点が指摘されていた。
【０００８】
上記の問題点を鑑み、棟瓦に適用でき地震や強風などの強い揺れに対しても崩壊せず、簡単な施工方法で実施可能な棟瓦防災のための棟瓦固定バンドを提供して、且つ新築、改築を問わず施工可能を目的とした。
【０００９】
【課題を解決するための手段】
本発明は、上記課題を解決するためになされたものであり、その要旨とするところは、和風瓦葺きの棟瓦の外観形状に沿って、桟瓦の桟心部までフランジ部を形成した半円形の帯板状の固定バンドにて挟み付け、該固定バンドのフランジ部に穿孔した丸孔より長尺ビスを、桟瓦の桟心部を通して野地板や垂木へ螺着して、上記固定バンドにてのし瓦や冠瓦の上面より圧着することで地震や強風などの災害による大棟や隅棟の被害を防止する対策を施したことを特徴とする棟瓦固定バンドに関するものである。
【００１０】
【発明の実施の形態】
本発明を図面の実施例を参照しながら詳細に説明する。
（実施例１）
図１、図２に於て、Ａは和風瓦葺きの大棟１に施工された本発明の棟瓦固定バンドを示し、該固定バンドＡは、のし瓦２、冠瓦３を締着して桟瓦４の桟心部３０より穿設された２つの丸孔２２より長尺ビス１８で野地板７から垂木６まで螺着される。場合によっては瓦桟木１７にも螺着させることも可能であるり、後述の図１１で詳細に説明する。
更に隅棟に対しても同様の棟瓦固定バンドＡの施工が可能であり、後述の図１２、図１３、図１４において詳細に説明する。
【００１１】
本発明の棟瓦固定バンドＡは、大棟１の長手方向に対し、一般に１乃至２個の冠瓦３の間隔を空けて配設される。また改築家屋の大棟１に於ては、修理部分の冠瓦３を重点的に位置決定して棟固定バンドＡが取り付けられる。
【００１２】
また本発明の棟瓦固定バンドＡの取付けは、従来の図５ａの心しばり施工や千鳥格子施工などと併用した方が好ましく、地震や強風対策の防災構造の効果が更に発揮されるものである。
【００１３】
一般に棟瓦固定バンドＡは、防錆・加工性を考慮しステンレス性の約２ｍｍ程度の帯板で製作されるが、亜鉛鉄板や銅板、耐候性樹脂板などでも強度が同等であれば使用しても構わない。且また各種の屋根瓦の美観を損ねない様に塗装を施しても問題はない。
【００１４】
そこで図２ａ、図２ｂに於て、本発明の棟瓦固定バンドＡの取付け状態を更に詳しく説明すると、従来の棟瓦の施工と同様に、予め棟木５、垂木６、野地板７を使用して屋根１１の傾斜面を形成させ、瓦桟木１７を所定の位置に釘８で固定させて配設し、該瓦桟木１７に桟瓦４を均衡に掛止して、瓦取付用釘９で固定されることにより棟部分が構成される。然る後に棟土１０を棟部分の桟瓦４の上に載せ、その周囲にのし瓦２、棟土１０、のし瓦２、と順次積み上げして最後に冠瓦３を載せて施工された棟瓦の左右に渡設するように半円形に屈曲させてステンレスの帯板を装設し、且つ両端を桟瓦４の桟心部３０の傾斜に角度を合わせて折り曲げたフランジ部２３を形成して棟瓦固定バンドＡが固着される。
【００１５】
棟瓦固定バンドＡのフランジ部２３には２つの丸孔１６が穿設され、桟瓦４の桟心部３０に振動ドリルの刃で穿設された丸孔２２に防水ゴム１９が挿通された長尺ビス１８を該丸孔２２に差込み、野地板７及び垂木６へ螺着させる。更に棟瓦固定バンドＡの緩みに留意して左右共に同一の締め力で長尺ビス１８より螺着される。
【００１６】
棟瓦固定バンドＡと冠瓦３やのし瓦２の隙間にはシーリング材２４やスポンジ材などでコーキングを実施して棟瓦固定バンドＡの横ズレをなくし防水対策を施すものとする。
【００１７】
（実施例２）
図３ａに於て、防水ゴム１９が挿通された長尺ビス１８で棟瓦固定バンドＡを螺着する場所に垂木６が位置している場合は、本仕様の棟瓦固定バンドＡが固定されるが、垂木６が該場所になくズレている場合に於て、図３ｂのように野地板７の裏面より平座金２０、ナット２１を利用して長尺ボルト３２で螺着することにより緊結状態として棟瓦固定バンドＡが固定される。
なお、以上の実施例では野地板７の板厚が８ｍｍ未満の場合で説明したが、野地板７の板厚が８ｍｍ以上を有している場合には長尺ビス１８を使用して、長尺ボルト３２にナット２１を螺着しなくても済む。
【００１８】
（実施例３）
また、図１１のように棟瓦固定バンドＣのフランジ部２３を桟瓦４の桟心部３０の端部まで来るように延長して、長尺ビス１８をフランジ部２３の丸孔２２より瓦桟木１７及び野地板７並びに垂木６へと螺入して緊締固止させることもできる。
【００１９】
次に図１０ａのように、桟瓦４と野地板７との間に檜、杉などの木製またはプラスチック製の下地材３４を野地板７を通じて垂木６へビス３５にて取付けしておいてから、長尺ビス１８を棟瓦固定バンドＡのフランジ部２３の丸孔２２より下地材３４および野地板７垂木６へ螺入して緊締固止させる。
【００２０】
また、図１０ｂに示すように、桟瓦４と野地板７との間に同じく檜、杉などの木製またはプラスチック製からなる下地材３４を野地板７並びに垂木６へビス３５にて取付けしておいてから、長尺ボルト３２を棟瓦固定バンドＡのフランジ部２３の丸孔２２より下地材３４および野地板７へ螺入して、野地板７にて平座金２０を介してナット２１にて緊締固止する。
なお、図中１９は防水ゴムである。
このように野地板７並びに垂木６へ取付けした下地材３４へ長尺ビス１８を螺入して野地板７にてナット２１にて緊締固止したことにより、大棟１が棟瓦固定バンドＡにて頗る安全堅牢に固定される。
【００２１】
（実施例４）
図６ａに於て、特に改築用の家屋の棟瓦にあっては、心しばり施工や千鳥格子施工の銅線が切れかかっていたり、または冠瓦３が破損し一部修繕する場合は、棟瓦全体を工事する必要はなく、ステンレス製金網２５や耐候性の樹脂製ネットなどをのし瓦２の長手方向に覆い被せ、該金網２５やネットなどの上面より棟瓦固定バンドＡを所定の間隔で配設・固着することにより対応ができる。
【００２２】
（実施例５）
更に図６ｂに於て、ステンレス製金網や耐候性の樹脂製ネットなどの変わりにステンレス製帯板２６を冠瓦３の長手方向に添設させ、該帯板２６の上から棟瓦固定バンドＡで固着することにより冠瓦３のズレ対策とすることもできる。本仕様にあっては冠瓦３の部分修繕に対しても有効な方法である。
【００２３】
（実施例６）
図７、図８に於て、桟瓦４は必ずしも大棟の左右傾斜面に対向して均等に配列されている訳でなく、数センチの桟心部３０の前後ズレが発生している場合がある。その場合棟瓦固定バンドＡを半円形のまま渡し込むと桟心部３０の偏心により長尺ビス１８が桟心部３０に螺着できない状態となる。その対策としてステンレス製補助プレート２７を係止して偏心を吸収することになる。該補助プレート２７は、着脱可能とするため、ボルト・ナット２８でフランジ部２３に固定される。
【００２４】
（実施例７）
図９ａ、図９ｂに於て、棟瓦固定バンドＢは、大棟の形状に合わせて製作されるため、実施例１の形状とは別にのし瓦２を積み上げる際に段違いにして施工するものがあり、該仕様に対しても棟瓦固定バンドＢとして段曲げ加工３１を施して、のし瓦の段違い部に合致させて対応できる。またのし瓦２を本図３段以上の高さにした大棟（図示なし）や冠瓦３が本図の半円形でなく特殊な形状を成した大棟（図示なし）などにも棟瓦の断面形状に沿わせて棟瓦固定バンドが成形され、尚且、棟瓦固定バンドのフランジ部に関し、長く成形して（図示せず）複数本のビスで留める形状にすることも対応することができる。
【００２５】
図１２は本発明の棟瓦固定バンドＡを隅棟Ｄへ使用した場合を示すものであって、この際も棟瓦固定バンドＡの両フランジ部２３がそれぞれ桟瓦４の桟心部３０上にあるので、該フランジ部２３の丸孔より長尺ビスまたは長尺ボルトにて螺入して緊締固止するものであることは図２ａ、図２ｂのときと同様の取付方法である。
【００２６】
図１３は隅棟Ｄと双方の桟瓦４の桟心部３０との位置の関係上、棟瓦固定バンドＣのフランジ部２３の長さが左右異なった場合示すものであって、隅棟Ｄへ桟瓦固定バンドを固着する方法は上記に述べた固定方法と全く同一であることは言う迄もない。
【００２７】
また、図１４は図１３に示すものとの別の実施例を示すものであって、この場合は補助プレート３６をフランジ部２３と桟瓦４の桟心部３０との間に介在して長尺ビス１８または長尺ボルト３２にて螺着して棟瓦固定バンドＡを隨意に隅棟Ｄへ取付けできる場合を説明したものである。
【００２８】
【発明の効果】
本発明の棟瓦固定バンドは、半円形の帯板状の固定バンドにて構成され、該棟瓦固定バンドのフランジ部より長尺ビスを螺入して、多種多様の和風瓦葺きの棟瓦の外観形状に沿わせて緊締固止したから大棟、隅棟などを強固に保持できる。
【００２９】
本発明は、冠瓦の上面から固定バンド方式で桟瓦の桟心部より長尺ビスを専用下地材、瓦桟木、野地板、および垂木へ確実に螺着されるようにしたから、地震屋強風などに対する防災構造を成し、心しばり施工や千鳥格子施工などの敷設を併用して施工することにより、更に強化な防災構造となり汎用性に優れ利用価値の高いものである。
【００３０】
また、桟瓦と野地板との間に不腐食性に富んだ檜、杉など木製またはプラスチック製の下地材を介在して長尺ビスにて螺着したから、より完全堅固に固定できる。
【００３１】
本発明は、冠瓦の天井長手方向に帯板を添設し、または冠瓦やのし瓦の長手方向に金網を覆設して棟瓦固定バンドでのし瓦や冠瓦の上面より圧着したから、既存の棟瓦の部分修繕に有効で、更に堅固な防災発明といえる。
【００３２】
本発明は、大棟の左右傾斜面に対向する桟瓦の桟心部が偏心した瓦葺き施工に、補助プレートを介在して、棟瓦固定バンドをのし瓦や冠瓦の上面より圧着したから、新築や改築の家屋を問わず既存の棟瓦でも補強対策を施すことができるものである。
【００３３】
本発明は、冠瓦の外形、及びのし瓦の段違い積みに合わせて帯板状の固定バンドを段曲げ加工した屈曲部をのし瓦の略下部段違い部に合致させて、棟瓦固定バンドをのし瓦や冠瓦の上面より圧着したから、のし瓦が３段以上の高さにした大棟や冠瓦が半円形でなく特殊な形状を成した大棟などにも棟瓦の断面形状に沿わせて棟瓦固定バンドを成形することができ、優れた汎用性を有する発明である。
【００３４】
本発明は、固定バンド方式であるため、新築や改築の家屋を問わず施工でき、特に既存の棟瓦の部分修繕には解体する部分が小範囲で済み、防災構造でない既存の棟瓦でも補強対策を施すことができる極めて優れた発明といえる。
【００３５】
本発明は、外部固定バンド方式であるため、現在行われている棟耐震工法の棟内部で補強される施工方法より欠陥が発見し易く、外部より簡単に補修ができるのでメンテナンスにも優位性を有している。
【００３６】
新築家屋の棟瓦施工に於いては予め棟瓦固定バンドの高さ、形状に合わせてのし瓦の段数を調節でき、施工ロスが少なく熟練者には極めて利便性の高いものである。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a ridge tile fixing band of a tile (hereinafter referred to as a ridge tile) such as a large ridge, a land ridge, a falling ridge, a corner ridge, and the like, and more particularly to a rafter, a field board, and a special base material using the ridge tile fixing band. The present invention relates to a fixed roof tile band for disaster prevention in the event of earthquakes and strong winds, in which the roof tiles and crown tiles are stably and firmly secured by being screwed onto the roof.
[0002]
[Prior art]
Conventionally, the structure of the ridge part in the roofing work of Japanese style architecture is a houndstooth check construction in which multiple layers of stacked tiles and crown tiles are tied together with copper wire, and a hook-shaped A method of hanging a copper wire on a nail and inserting the ends of the copper wire into a crown tile installed at the top of a plurality of stacked tiles and binding them at the center is generally adopted. It is the present situation.
[0003]
4a and 4b illustrate a staggered grid construction and FIG. 5a and FIG. 5b illustrate a centering construction. FIG. 5a and FIG. 5b illustrate that a sloped surface of a roof 11 is formed in advance using a purlin 5, a rafter 6, and a base plate 7. The tile block 17 is fixed at a predetermined position with a nail 8 and disposed, and the tile 4 is fixed to the tile block 17 in a balanced manner and fixed with the tile binding nail 9 to form a ridge portion. You. After that, the ridge 10 is placed on the ridge 4 of the ridge portion, and the tile 2, the ridge 10, and the tile 2 are sequentially stacked around the ridge, and finally the crown tile 3 is placed on the ridge 1. Is completed.
[0004]
Therefore, as shown in FIGS. 4A and 4B, copper wires 13 for binding are placed in advance, and before the construction of the roof tiles, they are laid in a staggered manner in the longitudinal direction of the large building 1 in the left-right direction, and are included in the ridge 10. Furthermore, when the roof tile 2 and the crown tile 3 are placed, and when the construction of the ridge tile is completed in one line, another binding copper wire 12 is passed over the existing copper wire 13 and knitted in a left and right and staggered lattice shape. Is the houndstooth construction.
[0005]
As shown in FIGS. 5A and 5B, hook-shaped nails 15 are cast on the roof base such as the purlin 5 and the base plate 7, and the nails 15 are hung with copper wires 14 for fastening. The soil 10 and the roof tile 2 are piled up, and finally two round holes 33 are formed in the center of the ceiling of the crown tile 3, and the copper wire 14 for binding is inserted and bound to form the large building 1. The fixation work is the fixation.
[0006]
[Problems to be solved by the invention]
However, in the above-described houndstooth construction, the copper wire that connects the roof tile and the crown tile only penetrates the ridge, but is not locked to the field board or other structure of the building. In addition, if the copper wire for binding has been corroded or broken after the age of construction, since the copper wire is continuously laid, the ridge will easily collapse due to an earthquake or strong wind, etc. Had to be dropped or blown away.
[0007]
In addition, in the above-mentioned clinching construction, in the structure of the roof tile and the crown tile, since it is almost fixed to the ridge, one point of the hook-shaped nail against lateral force such as earthquake or strong wind When the roof tile structure collapses once, the weight is involved and the roof easily falls one after another, which is not suitable for disaster prevention. Also, it has been pointed out that a hook-shaped nail is fixed to a purlin, but a force acts in a direction in which the nail is easily detached, and the nail falls off.
[0008]
In view of the above problems, the building tile fixed band for building tile disaster prevention that can be applied to the building tile, does not collapse even by strong shaking such as earthquake or strong wind, and can be implemented with a simple construction method, and The purpose was to be able to perform construction regardless of remodeling.
[0009]
[Means for Solving the Problems]
The present invention has been made in order to solve the above-mentioned problems, and the gist of the present invention is to provide a semi-circular band in which a flange portion is formed up to a core portion of a cross tile along the external shape of a Japanese style tiled ridge roof tile. A long screw is screwed from a round hole perforated in the flange portion of the fixed band through the pier portion of the tiling to a field board or a rafter, and is put on the fixed band. The present invention relates to a fixed tile for a ridge roof tile, which has been subjected to measures for preventing damage to a large wing or a corner ridge due to a disaster such as an earthquake or a strong wind by being pressed from the upper surface of a roof tile or a roof tile.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be described in detail with reference to the embodiments in the drawings.
(Example 1)
1 and 2, A denotes a ridge roof tile fixing band of the present invention installed on a Japanese-style tiled large building 1, and the fixing band A includes a roof tile 2 and a crown tile 3 by fastening a roof tile. The screw is screwed from the base plate 7 to the rafter 6 with the long screw 18 from the two round holes 22 drilled from the pier portion 30 of No. 4. Depending on the case, it is also possible to screw it on the roof tile 17 and it will be described later in detail with reference to FIG.
Further, the same roof tile fixing band A can be applied to the corner ridge, and will be described in detail with reference to FIGS. 12, 13, and 14 described later.
[0011]
The ridge roof tile fixing band A of the present invention is generally arranged with one or two crown roof tiles 3 spaced apart from each other in the longitudinal direction of the main ridge 1. In addition, in the large building 1 of the renovated house, the ridge fixing band A is attached by mainly determining the position of the crown tile 3 in the repaired portion.
[0012]
Further, the mounting of the ridge tile fixing band A of the present invention is preferably used in combination with the conventional centering construction or the houndstooth construction of FIG. 5A, so that the effect of the disaster prevention structure against earthquakes and strong winds is further exhibited. .
[0013]
Generally, the roof tile fixing band A is made of a stainless steel strip of about 2 mm in consideration of rust prevention and workability, but a zinc iron plate, a copper plate, a weather-resistant resin plate, etc. may be used if the strength is the same. No problem. In addition, there is no problem even if coating is performed so as not to impair the aesthetic appearance of various roof tiles.
[0014]
2A and 2B, the attached state of the ridge tile fixing band A of the present invention will be described in more detail. As in the case of the conventional ridge roof tile construction, the roof is previously used by using the ridge 5, the rafter 6, and the field board 7. 11 is formed, and the timber crosspiece 17 is fixed at a predetermined position with a nail 8 and disposed. The tiling 4 is evenly hooked to the tile timber 17 and fixed with the tile mounting nail 9. This forms the ridge. After that, the ridge 10 was placed on the roof tile 4 of the ridge part, and the tile 2, the ridge 10, and the tile 2 were piled up in that order, and finally the crown tile 3 was placed. A stainless steel band plate is provided by bending in a semicircle so as to extend to the left and right of the roof tile, and a flange portion 23 is formed by bending both ends at an angle to the inclination of the core 30 of the roof tile 4. The roof tile fixing band A is fixed.
[0015]
Two round holes 16 are formed in the flange portion 23 of the ridge roof tile fixing band A, and a waterproof rubber 19 is inserted through a round hole 22 formed in the core 30 of the cross tile 4 with a blade of a vibration drill. The screw 18 is inserted into the round hole 22 and screwed to the base plate 7 and the rafter 6. Furthermore, the left and right screws 18 are screwed from the long screw 18 with the same tightening force, taking into account the looseness of the ridge roof fixing band A.
[0016]
Caulking is performed with a sealing material 24, a sponge material, or the like in the gap between the ridge roof tile fixing band A and the crown roof tile 3 or the shingle roof tile 2 to eliminate lateral displacement of the ridge roof tile fixing band A and take waterproofing measures.
[0017]
(Example 2)
In FIG. 3A, when the rafter 6 is located at the place where the long ridge fixing band A is screwed with the long screw 18 into which the waterproof rubber 19 is inserted, the ridge roof fixing band A of this specification is fixed. In the case where the rafter 6 is not located at the place and is displaced, as shown in FIG. 3B, a tightening state is established by screwing the back surface of the base plate 7 with the long bolt 32 using the flat washer 20 and the nut 21. The roof tile fixing band A is fixed.
In the above embodiment, the case where the thickness of the base plate 7 is less than 8 mm has been described. However, when the thickness of the base plate 7 is 8 mm or more, the long screw 18 is used. It is not necessary to screw the nut 21 to the measuring bolt 32.
[0018]
(Example 3)
Also, as shown in FIG. 11, the flange portion 23 of the ridge roof tile fixing band C is extended so as to reach the end of the pier portion 30 of the roof tile 4, and the long screw 18 is inserted through the round hole 22 of the flange portion 17 into the tile pier 17. It can also be screwed into the base plate 7 and the rafter 6 to be tightened and secured.
[0019]
Next, as shown in FIG. 10 a, a wooden or plastic base material 34 such as cypress, cedar, etc. is attached to the rafter 6 with the screw 35 between the cross tile 4 and the base plate 7 through the base plate 7, The long screw 18 is screwed into the base material 34 and the base plate 7 rafter 6 through the round hole 22 of the flange portion 23 of the ridge roof fixing band A and tightened.
[0020]
As shown in FIG. 10b, a base material 34 made of wood or plastic, such as cypress or cedar, is attached to the base board 7 and the rafter 6 with screws 35 between the cross tile 4 and the base board 7. After that, the long bolt 32 is screwed into the base material 34 and the base plate 7 from the round hole 22 of the flange portion 23 of the ridge roof fixing band A, and tightened with the base plate 7 via the flat washer 20 and the nut 21. Secure.
In the figure, reference numeral 19 denotes a waterproof rubber.
In this way, the long screw 18 is screwed into the base material 34 attached to the base plate 7 and the rafter 6, and is tightened and fastened with the nut 21 at the base plate 7, so that the large ridge 1 becomes the ridge tile fixing band A. Very secure and secure.
[0021]
(Example 4)
In FIG. 6a, especially in the case of the roof tile of a house for renovation, if the copper wire of the clinging construction or the houndstooth construction is cut or if the crown tile 3 is damaged and partially repaired, the roof tile is required. It is not necessary to construct the entire structure. A stainless steel wire mesh 25 or a weather-resistant resin net is placed on the roof 2 in a longitudinal direction of the roof 2 and the ridge roof fixing band A is placed at a predetermined interval from the upper surface of the wire mesh 25 or the net. It can be handled by arranging and fixing.

(Example 6)
In FIGS. 7 and 8, the cross tiles 4 are not necessarily uniformly arranged facing the left and right inclined surfaces of the large building, and a misalignment of the cross core portion 30 of several centimeters may occur. is there. In this case, if the ridge tile fixing band A is passed in a semicircular shape, the long screw 18 cannot be screwed to the pier 30 due to the eccentricity of the pier 30. As a countermeasure, the eccentricity is absorbed by locking the stainless steel auxiliary plate 27. The auxiliary plate 27 is fixed to the flange 23 with bolts and nuts 28 so as to be detachable.
[0024]
(Example 7)
In FIGS. 9a and 9b, the roof tile fixing band B is manufactured according to the shape of the large building. In addition, it is possible to cope with the specification by performing the step bending process 31 as the ridge roof tile fixing band B so as to match the uneven portion of the roof tile. In addition, roof tiles are also used in large buildings (not shown) in which the roof tiles 2 have a height of 3 steps or more in this figure, and large buildings (not shown) in which the crown tiles 3 have a special shape instead of the semicircular shape in this figure. The ridge roof fixing band is formed along the cross-sectional shape of the ridge roof tile, and the flange portion of the ridge roof fixing band can be formed to have a long shape (not shown) to be fastened with a plurality of screws.
[0025]
FIG. 12 shows a case where the ridge roof tile fixing band A of the present invention is used for the corner ridge D. In this case also, since both the flange portions 23 of the ridge roof tile fixing band A are respectively on the pier 30 of the cross tile 4. 2A and 2B is a method in which a screw is inserted into the round hole of the flange portion 23 with a long screw or a long bolt to secure it tightly.
[0026]
FIG. 13 shows a case in which the length of the flange portion 23 of the ridge-roof fixing band C is left and right different due to the positional relationship between the corner ridge D and the pier portions 30 of both the cross-tiles 4. It goes without saying that the fixing method of the fixing band is exactly the same as the fixing method described above.
[0027]
FIG. 14 shows another embodiment different from that shown in FIG. 13. In this case, an auxiliary plate 36 is interposed between the flange 23 and the core 30 of the roof tile 4 to be long. This illustrates a case where the ridge roof fixing band A can be attached to the corner ridge D by screwing with the screw 18 or the long bolt 32.
[0028]
【The invention's effect】
The ridge tile fixing band of the present invention is composed of a semicircular band plate-shaped fixing band, and a long screw is screwed into the flange portion of the ridge tile fixing band to form a variety of Japanese-style tiled ridge roof tiles. The main building and the corner building can be held firmly because they are tightly secured along the road.
[0029]
The present invention uses a fixed band method from the upper surface of the crown tile to securely screw a long screw from the core portion of the roof tile to a dedicated base material, a tile pier, a field board, and a rafter. By constructing a disaster-prevention structure against such a problem and laying it together with laying and houndstooth construction, it becomes a more reinforced disaster-prevention structure and is highly versatile and highly useful.
[0030]
In addition, since a wooden or plastic base material such as cypress or cedar, which is rich in non-corrosiveness, is interposed between the roof tile and the ground board and screwed with a long screw, it can be fixed more completely and firmly.
[0031]
In the present invention, a band plate is attached to the roof tile in the longitudinal direction of the roof tile, or a wire mesh is covered in the longitudinal direction of the roof tile and the roof tile, and the upper side of the roof tile or the roof tile is crimped with the ridge roof tile fixed band. Therefore, it can be said that it is effective in repairing existing roof tiles and is a more robust disaster prevention invention.
[0032]
The present invention is based on the fact that the roof tiles facing the left and right inclined planes of the large building are eccentric, and an auxiliary plate is interposed between the roof tiles and the roof tile fixing band is mounted on the roof tiles and crimped from the upper surface of the tile or crown tile. Existing roof tiles can be provided with reinforcement measures regardless of whether the building is renovated or renovated.
[0033]
The present invention relates to a ridge roof tile fixed band, in which a bent portion obtained by step-bending a strip-shaped fixed band in accordance with the outer shape of a crown tile and a stepped pile of a tiled tile is matched with a substantially lower stepped portion of the tile. The cross-sectional shape of the roof tile is also applied to large buildings where the height of the roof tile is three steps or more and large buildings where the roof tile is not semi-circular but has a special shape because it is pressed from the top of the roof tile or crown tile It is an invention having excellent versatility in which a roof tile fixing band can be formed along the shape of the ridge tile.
[0034]
Since the present invention is a fixed band system, it can be constructed regardless of new or renovated houses.Particularly, repair of existing building tiles requires only a small area to be dismantled, and reinforcement measures can be applied to existing building tiles that are not disaster prevention structures. It can be said that this is an extremely excellent invention that can be applied.
[0035]
Since the present invention uses an external fixed band system, it is easier to find defects than the construction method reinforced inside the ridge of the ridge seismic construction method currently being performed, and it can be repaired easily from the outside, so it has an advantage in maintenance. Have.
[0036]
When building roof tiles for a new house, the number of steps of the roof tiles can be adjusted in advance according to the height and shape of the roof tile fixing band, and the construction loss is small, making it extremely convenient for skilled workers.
