Description

【0001】
【産業上の利用分野】
本発明は、山部と谷部を交互に形成した面板部を有し、面板部の軒側を折り下げてから棟側(裏面側)に折り曲げた係合部を有し、面板部の棟側を立ち上げてから軒側(表面側)に折り曲げた係止部を有していて、係止部を吊子で固定する金属成型瓦に関するものである。
【0002】
【従来の技術】
従来技術の一例として、実用新案公告平成4年第27935号に示された成形瓦屋根材の平瓦部がある。ここに示された成形瓦屋根材の平瓦部を、本願発明と統一させて「金属成型瓦」として説明する。この金属成型瓦は、頂部が平らである山部と、谷部を交互に形成し、軒側を折り下げてから棟側に折り曲げて係合部を形成し、棟側を立ち上げてから軒側に折り曲げて係止部を形成してある。そして、係止部の谷部に吊子をかぶせて止着具を用いて金属成型瓦を下地材に固定し、そこに、上の段に施工する金属成型瓦を組み合わせて施工していく。
【0003】
【発明が解決しようとする課題】
この考案に示された金属成型瓦は、山部の頂部の形状が平らであり、そこに金具を固定し、その金具に丸瓦部をかぶせていくことを主眼としている。このため、美しい曲面を描く山部を形成する工夫は成されておらず、その代わりに丸瓦部をかぶせることで、山部の外観を曲面状にしていた。
【0004】
【課題を解決するための手段】
本発明の金属成型瓦は、概略として、金属板を金型でプレス成型して形成されるものであり、吊子を用いて固定していく。具体的には、曲面状である山部及び、谷部を交互に形成した面板部と、面板部の軒側を折り下げてから棟側(裏面側)に折り曲げた係合部と、面板部の棟側を立ち上げてから軒側(表面側)に折り曲げた係止部とを有している。
係合部において棟側への折り曲げ箇所は、下面山部分と下面谷部分とから成る係合部下面となっており、係止部において軒側への折り曲げ箇所は、上面山部分と上面谷部分とから成る係止部上面となっている。上面谷部分には、吊子の厚みを考慮してくぼませた凹部分を形成するとよい。そして、この凹部分の左右方向の間隔を、下地材であるタルキのピッチに合うように設定して金属成型瓦の形状を設計するとよい。また、山部の両脇(山部と谷部との境目)に、意匠上のアクセントをつけて山部と谷部をくっきりさせるために、リブを入れてもよい。さらに、金属成型瓦を表面側から見たときに、係合部において、向かって右側かつ軒側を棟側に引っ込めて形成し、これに対し、係止部において、向かって左側かつ棟側を軒側に引っ込めて形成するとよい。このような係合部と係止部の形成は、左右を逆にしてもよい。
【0005】
そして、本発明の金属成型瓦は次のような構成を有していることが最大の特徴である。この金属成型瓦は、係合部下面において、少なくとも、吊子に組み合わせられる箇所の下面谷部分の軒−棟方向の幅を所定の幅としたときに、それ以外の係合部下面の幅は所定の幅よりも狭く形成されている。つまり、下面谷部分において、少なくとも吊子にかぶさる部分の幅(軒−棟方向の幅)を基準としたときに、それ以外の係合部下面の幅がより狭くなっているのである。
【0006】
このような金属成型瓦を、吊子を用いて施工していくが、その吊子は、たとえば、固定面を有し、固定面の一側を略直角に立ち上げた立面部と、立面部の上縁を固定面とは反対方向に略直角に折り曲げた平面部と、平面部を折り下げた折り下げ部とを有したものにするとよい。そして、このような吊子を金属成型瓦の係止部上面にかぶせ、釘等の止着具により固定面を下地材に固定する。
左右方向の金属成型瓦の施工は、すでに施工されている金属成型瓦に、隣りに施工する金属成型瓦を重ねて行う。このとき、重なり部分の下側となる山部に溝部分を形成して、毛細管現象を防ぐとよい。
軒−棟方向の金属成型瓦の施工は、上の段(棟側)に施工する金属成型瓦の係合部を、下の段(軒側)に施工されている金属成型瓦の係止部を固定している吊子に組み合わせるようにして行う。
【0007】
【作用】
本発明の金属成型瓦は、金属板をプレス成型して製作されるが、このとき、プレスする金属板をカットする際、係合部下面において、少なくとも、下の段に施工されている金属成型瓦を固定している吊子に組み合わせられる箇所の下面谷部分の幅を所定の幅としたときに、それ以外の係合部下面の幅を所定の幅よりも狭くしておくのである。
下面山部分の幅と下面谷部分の幅とを同じにすることなく、下面山部分の方を幅狭くしておくことにより、金属板をプレス成型したときの特徴である次のような現象を防ぐのである。つまり、係合部の折り下げ箇所と係止部の立ち上げ箇所を形成し、次に係合部下面と係止部上面とを形成するが、このプレス成型過程で、山部の頂部付近が折り下げられて最も金属板が縮もうとする箇所では、布地にシワが寄ったような状態になり、さらに係合部下面を形成しようと折り曲げたときに金属板が広がって波状になってしまい、反対に、金属板が伸びようとする箇所である山部と谷部との境目においては、その過程で亀裂が生じてしまう現象である。
【0008】
【実施例】
本発明の実施例について、図面をもとに説明する。図1は本発明の金属成型瓦の背面図(裏面側から見た図)であり、図2は正面図(表面側から見た図)であり、図3は平面図であって棟側となる方向から裏面側を上にして見た図であり、図4は底面図であって軒側となる方向から見た図であり、図5は左側面拡大図であり、図6は右側面拡大図であり、図7は図2中A−A線で切断したときの一部拡大図であり、図8は図2中B−B線で切断したときの拡大図であり、図9は図2中C−C線で切断したときの拡大図であり、図10は図2中D部の拡大図であり、図11は図2中E部の拡大図であり、図12は全体形状を示す斜視図であり、図13は施工状態を示す説明図である。
【0009】
図1から図12により、本発明の金属成型瓦Aの実施例について説明する。この金属成型瓦Aは、金属板を金型でプレスして形成されるものであり、本実施例の場合には金属板をカットしてから、山部4と谷部5を形成したり、係止部1と係合部2を形成したりするといった工程を経る。そして、曲面状である山部4及び、谷部5を交互に形成した面板部3と、面板部3の軒側を折り下げてから棟側(裏面側)に折り曲げた断面略コ字状の係合部2と、面板部3の棟側を立ち上げてから軒側(表面側)に折り曲げた断面略コ字状の係止部1とを有している。本実施例の金属成型瓦Aは、山部4と谷部5の高低差が約20ミリであるが、谷部5の形状をほぼ平坦にしているため曲面状の山部4が強調されている。
【0010】
係合部2において棟側への折り曲げ箇所は、下面山部分21aと下面谷部分21bとから成る係合部下面21となっており、係止部1において軒側への折り曲げ箇所は、上面山部分11aと上面谷部分11bとから成る係止部上面11となっている。そして、上面谷部分11bには、後述する吊子Bが載る凹部分12が形成されている。この凹部分12は、吊子Bの厚みを考慮してくぼませてあり、たとえば施工中に上から踏んだときに、吊子Bの跡が金属成型瓦A表面側に出て美観を損ねるのを防いでいる。
また、本実施例の金属成型瓦Aは、凹部分12の左右方向の間隔が、下地材の一部であるタルキのピッチに合うように設定されて設計が成されている。このようにしておけば、最初の施工のときに位置決めをすることで、その後の吊子B止めが容易にできる。本実施例の場合には、2つおきに吊子Bを止めていくと455ミリピッチのタルキに合うようになっている。
尚、本実施例のように、山部4の両脇(山部4と谷部5との境目)に、意匠上のアクセントをつけて山部4と谷部5をくっきりさせるために、リブ31・31を入れてもよい。
【0011】
そして、本実施例の金属成型瓦Aは、左右方向及び軒−棟方向に組み合わせて施工していくため、次のような構成になっている。まず、すでに施工されている金属成型瓦Aの向かって右側(図2の右側)に、隣りに施工する金属成型瓦Aの左側(図2の左側)を組み合わせていく。このとき、金属成型瓦Aに向かって右側であって軒側である係合部2は図11にも示した通り棟側に引っ込めて形成されている。これに対して、向かって左側であって棟側である係止部1は図10にも示した通り軒側に引っ込めて形成されている。このため、左右に隣り合う金属成型瓦A・Aの係合部2・2同士及び係止部1・1同士を組み合わせたときに、軒側が不揃いになることがなく略一直線上に揃い、美観を損ねることなく一体感が保てるし、隙間から雨水が浸入しにくい。
また、右側端部の山部4の頂部(つまり、重なり部分の下側となる方)には溝部分41が形成されており、万一面板部3・3同士の組み合わせ部分の隙間から吹き上げるように雨水が浸入しても、毛細管現象により内部へ浸入するのを防いでいる。
【0012】
さらに、本発明の金属成型瓦Aは次のような工夫が成されていることが特徴である。この金属成型瓦Aは、係合部下面21において、下面山部分21aの幅が所定の幅よりも狭く形成されている。つまり、係合部下面21において下面谷部分21bの幅を基準としたときに、下面山部分21aの幅の方がより狭くなっているのである。係合部下面21において、少なくとも、下の段に施工されている金属成型瓦Aを固定している吊子Bに組み合わせられる箇所の下面谷部分21bの幅を所定の幅としたときに、それ以外の箇所の係合部下面21の幅は所定の幅よりも狭く形成されている。つまり、下面谷部分21bにおいて、少なくとも吊子Bがかぶせられる部分の幅(軒−棟方向の幅)を基準としたときに、それ以外の係合部下面21の幅がより狭くなっているのである。言い換えれば、幅の広い箇所は、少なくとも吊子Bに組み合わせる箇所であればよい。
【0013】
本発明の金属成型瓦Aは、金属板をプレス成型して製作されるが、このとき、プレスする金属板のカット形状において、係合部下面21の下面山部分21aの幅と下面谷部分21bの幅とを同じにすることなく、下面山部分21aの方を幅狭くしておくのである。基準となる、幅の広い箇所は、少なくとも下面谷部分21bにおいて、吊子Bに組み合わせられる箇所であって、その幅は吊子Bがかぶせられる部分の軒−棟方向の幅である。
もし同じ幅であったならば、すでに説明した通り、プレス成型したときに、山部4の頂部付近が折り下げられて最も金属板が縮もうとする箇所では、布地にシワが寄ったような状態になり、さらに係合部下面21を形成しようと折り曲げたときに金属板が広がって波状になってしまい、反対に、金属板が伸びようとする箇所である山部4と谷部5との境目においては、その過程で亀裂が生じてしまう現象がおき、美しいアールを描く山部4とはならず、定められた寸法で美麗な曲面を描くことなく、製品として成り立たなくなってしまうのである。特に、軒側であって係合部2の折り下げ箇所は隠れる箇所ではないので、屋根面全体にわたって形状不良なものが表に出ることがあってはならない。
【0014】
このように、係合部下面21において下面山部分21aの幅を所定の幅よりも狭くしても、係合部下面21における下面谷部分21bの幅は、少なくとも吊子Bに組み合わせられる箇所は所定の幅である。このため、係止部上面11の凹部分12に吊子Bがかぶせられ、そこに、上の段に施工する金属成型瓦Aの係合部2が組み合わせられたときに、係合部下面21の下面谷部分21bの幅は十分な幅であり、強度が保てるのである。また、下面谷部分21bと上面谷部分11bとのハゼ組み箇所は、雨水の浸入の恐れがあるが、少なくとも下面谷部分21bの吊子Bの部分が幅広くなっていたならば、深くかみ合わさるので、面板部3をさかのぼるようにして下面谷部分21bの下側から雨水が浸入しても、内部へ浸入しにくい。下面谷部分21bの幅が所定の幅であって、下の段に施工されている金属成型瓦Aを固定している吊子Bにしっかり組み合わせられるので、極端に言えば、下面山部分21aの幅は、端面の切り口が見えない程度の折り返しが成されている程度でもよい。
【0015】
このような金属成型瓦Aを吊子Bを用いて施工した状態を、図13により説明するが、まず吊子Bの実施例について説明する。図13に示した吊子Bは、固定面B1と、固定面B1の一側を略直角に立ち上げた立面部B2と、立面部B2の上縁を固定面B1とは反対方向に略直角に折り曲げた平面部B3と、平面部B3を折り下げた折り下げ部B4とを有している。本実施例の場合には、強度を増すために折り下げ部B4を階段状に折り下げてあり、さらにその下縁を内側方向に略直角に折り返してある。固定面B1には、あらかじめ穴をあけておくとよい。
【0016】
このような構成の吊子Bを、金属成型瓦Aの係止部上面11の凹部分12にかぶせ、固定面B1を、下地材(図示なし)に止着具で固定する。そして、上の段に施工する金属成型瓦Aの係合部2を、下の段に施工されている金属成型瓦Aを固定している吊子Bの折り下げ部B4に当てるようにしてかぶせて係止部1に組み合わせていく。別の表現をすると、上面谷部分11bに下面谷部分21bが、上面山部分11aに下面山部分21aがそれぞれハゼ組みされるようにして施工していくのである。
左右方向の金属成型瓦A・Aの施工は、すでに施工されている金属成型瓦Aにおいて溝部分41がある側の山部4(図2中右側)に、隣りに施工する金属成型瓦Aの山部4(溝部分41のない側の山部4、図2中左側)を重ね、続いて、その金属成型瓦Aを軒側から棟側に向かって動かして係止部1・1同士及び係合部2・2同士を組み合わせて行う。
【0017】
本実施例の金属成型瓦Aと吊子Bとを用いたならば、凹部分12があることによって吊子Bの厚みの影響を金属成型瓦Aの表面に及ぼすことなく施工することができる。また、溝部分41が形成されていることにより、金属成型瓦A・Aの面板部3・3同士の組み合わせ部分の隙間から吹き上げるようにして雨水が入り込んだとしても、毛細管現象により内部に浸入するのを防いでいる。
さらに、図10及び図11に詳しく描いた通り、図2中金属成型瓦Aに向かって右側であって軒側である係合部2は棟側に引っ込めて形成されており、これに対して、向かって左側であって棟側である係止部1は軒側に引っ込めて形成されている。このため、左右に隣り合う金属成型瓦A・Aの係合部2・2同士及び係止部1・1同士を組み合わせたときに、軒側が不揃いになることがなく略一直線上に揃い、美観を損ねることなく一体感が保てるし、隙間から雨水が浸入しにくい。
そのうえ、係合部2と係止部1の形状は断面略コ字状をしているため強度があるのに加え、吊子Bも、略直角の組み合わせによる形状であって、金属成型瓦Aが風で持ち上げられたときには、折り下げ部4Bの下縁によって上方向から係合部下面21の内側(裏面側)を押さえることができるのでいっそう強度が保てるものである。
【0018】
【発明の効果】
従来の金属成型瓦の山部は、頂部が平らなものとなっていて、美しい曲面を描く山部を形成する工夫は成されておらず、その代わりに丸瓦部をかぶせなければならなかったが、本発明の金属成型瓦によれば、係合部下面において、山部の幅が所定の幅よりも狭く形成されているので、きれいな曲面状の山部を形成することができる。

[Industrial applications]
The present invention has a face plate portion in which peaks and valleys are alternately formed, and has an engaging portion in which the eaves side of the face plate portion is folded down and then bent toward the ridge side (back side). The present invention relates to a metal-molded roof tile having a locking portion that is bent to the eaves side (front surface side) after the side is raised, and the locking portion is fixed by a hook.
[0002]
[Prior art]
As an example of the prior art, there is a flat tile portion of a molded tile roof material disclosed in Utility Model Publication No. 27935/1992. The flat tile portion of the roof tile material shown here is unified with the present invention and will be described as “metal roof tile”. This metal-molded roof tile is formed with alternating peaks and valleys with flat tops, folding down the eaves side, bending to the ridge side to form an engaging part, and erecting the ridge side, then erecting the ridge side. It is bent to the side to form a locking portion. Then, a metal mold roof tile is fixed to the base material using a fastener, and a metal mold roof tile to be installed on the upper tier is combined therewith to be installed.
[0003]
[Problems to be solved by the invention]
The metal molded roof tile shown in this invention has a flat shape at the top of the mountain, and the main purpose is to fix a metal fitting thereon and cover the metal roof with the round roof. For this reason, no attempt has been made to form a mountain portion that draws a beautiful curved surface, and instead, the appearance of the mountain portion is made to be a curved surface by covering it with a round tile portion.
[0004]
[Means for Solving the Problems]
The metal molded roof tile of the present invention is generally formed by press-molding a metal plate with a metal mold, and is fixed using a hanging element. More specifically, a face plate portion in which curved peaks and valleys are alternately formed, an engaging portion in which the eaves side of the face plate portion is folded down and then bent toward the ridge side (back side), and a face plate portion And a locking portion bent to the eaves side (surface side) after the ridge side is started up.
In the engaging portion, the bent portion toward the ridge side is the lower surface of the engaging portion composed of the lower surface peak portion and the lower surface valley portion, and the bent portion toward the eave side in the locking portion is the upper surface peak portion and the upper surface valley portion. And the upper surface of the locking portion. It is preferable to form a recessed portion in the upper valley portion in consideration of the thickness of the suspender. Then, it is preferable to design the shape of the metal-molded roof tile by setting the interval in the left-right direction of the concave portion so as to match the pitch of the base material, tarki. Also, ribs may be provided on both sides of the mountain (the boundary between the mountain and the valley) to give a design accent and to make the mountain and the valley clear. Further, when the metal molded tile is viewed from the front side, the right side and the eaves side are retracted toward the ridge side at the engaging portion, and the left side and the ridge side are viewed at the locking portion. It is good to retreat to the eaves side and form. The formation of such an engaging portion and a locking portion may be reversed left and right.
[0005]
The most significant feature of the metal molded roof tile of the present invention is that it has the following configuration. In the metal molded roof, when the width of at least the eaves-ridge direction of the lower surface valley portion of the lower surface of the portion to be combined with the suspender is a predetermined width on the lower surface of the engaging portion, the width of the other lower surface of the engaging portion is It is formed narrower than a predetermined width. In other words, in the lower valley portion, the width of the other lower surface of the engaging portion is smaller when at least the width (width in the eaves-ridge direction) of the portion that covers the hanging member is used as a reference.
[0006]
Such a metal-molded roof tile is constructed by using a hanging member. The hanging member has, for example, a fixed surface, and an upright portion in which one side of the fixed surface is raised substantially at a right angle, and It is preferable to have a flat portion in which the upper edge of the surface portion is bent at a substantially right angle in a direction opposite to the fixing surface, and a folded portion in which the flat portion is folded down. Then, such a hanging member is put on the upper surface of the locking portion of the metal molded roof tile, and the fixing surface is fixed to the base material with a fastener such as a nail.
The construction of the metal-formed tile in the left-right direction is performed by overlapping the metal-formed tile to be constructed next to the already-formed metal-formed tile. At this time, it is preferable to form a groove portion in a mountain portion below the overlapping portion to prevent the capillary phenomenon.
In the eaves-to-building direction, the metal-molded roof tiles are installed by engaging the metal-molded tiles on the upper level (ridge side) with the locking parts of the metal-type tiles on the lower level (eave side). Is carried out in such a way that it is combined with a fixed hanging element.
[0007]
[Action]
The metal-molded tile of the present invention is manufactured by press-molding a metal plate. At this time, when cutting the metal plate to be pressed, at least on the lower surface of the engaging portion, the metal molding is applied to the lower step. When the width of the lower surface valley portion of the portion to be combined with the suspender fixing the tile is set to a predetermined width, the width of the other lower surface of the engaging portion is made smaller than the predetermined width.
The following phenomena, which are the features of press-forming a metal plate, are achieved by making the bottom ridge narrower without making the width of the bottom ridge and width of the bottom valley the same. To prevent it. In other words, the folded portion of the engaging portion and the rising portion of the locking portion are formed, and then the lower surface of the engaging portion and the upper surface of the locking portion are formed. At the place where the metal plate is most likely to shrink when folded down, the fabric becomes wrinkled, and when it is bent to form the lower surface of the engaging portion, the metal plate spreads and becomes wavy On the contrary, at the boundary between the peak and the valley where the metal plate is about to extend, a crack is generated in the process.
[0008]

[0009]
An embodiment of the metal-molded roof tile A of the present invention will be described with reference to FIGS. The metal molded roof tile A is formed by pressing a metal plate with a mold. In the case of the present embodiment, the metal plate is cut, and then the peaks 4 and the valleys 5 are formed. A process of forming the engaging portion 1 and the engaging portion 2 is performed. Then, the face plate portion 3 in which the peak portions 4 and the valley portions 5 having a curved surface are alternately formed, and the eaves side of the face plate portion 3 are folded down and then bent toward the ridge side (back surface side) and have a substantially U-shaped cross section. It has an engaging portion 2 and a locking portion 1 having a substantially U-shaped cross section, which is formed by erecting the ridge side of the face plate portion 3 and then bending it toward the eaves side (surface side). Although the height difference between the peaks 4 and the valleys 5 of the metal molded roof tile A of this embodiment is about 20 mm, the curved ridges 4 are emphasized because the valleys 5 are almost flat. I have.
[0010]
The bent portion of the engaging portion 2 toward the ridge side is an engaging portion lower surface 21 composed of a lower surface peak portion 21a and a lower surface valley portion 21b. The locking portion upper surface 11 includes a portion 11a and an upper surface valley portion 11b. In the upper valley portion 11b, there is formed a concave portion 12 on which a hook B described later is placed. The concave portion 12 is depressed in consideration of the thickness of the hanging member B. For example, when stepping from above during construction, traces of the hanging member B appear on the surface side of the metal molded tile A and impair the appearance. Is preventing.
Further, the metal-molded roof tile A of the present embodiment is designed such that the interval between the concave portions 12 in the left-right direction is set to match the pitch of tarki which is a part of the base material. By doing so, positioning is performed at the time of the first construction, so that the suspension B can be easily fixed thereafter. In the case of this embodiment, stopping the hangers B at every third position is suitable for 455 mm pitch tarki.
As in the present embodiment, ribs are provided on both sides of the crest 4 (the boundary between the crest 4 and the valley 5) so that the design is accented to make the crest 4 and the valley 5 clear. 31 may be inserted.
[0011]
The metal-molded roof tiles A according to the present embodiment are constructed in the following manner because they are constructed in combination in the left-right direction and the eaves-ridge direction. First, the left side (the left side in FIG. 2) of the metal molded roof tile A to be constructed next to the right side (the right side in FIG. 2) of the already formed metal roof tile A is combined. At this time, the engaging portion 2 on the right side and the eaves side with respect to the metal roof tile A is formed to be retracted toward the ridge as shown in FIG. On the other hand, the locking portion 1 on the left side and on the ridge side is formed to be retracted toward the eaves side as shown in FIG. For this reason, when the engaging portions 2.2 of the metal molded roof tiles A adjacent to each other on the left and right and the locking portions 1.1 are combined, the eaves side are not aligned, but are aligned substantially in a straight line. It is possible to maintain a sense of unity without compromising the quality, and it is difficult for rainwater to enter through gaps.
Further, a groove portion 41 is formed at the top of the mountain portion 4 at the right end (that is, on the lower side of the overlapping portion), so that the groove portion 41 is blown up from the gap between the combined portions of the face plate portions 3.3. Even if rainwater enters the area, it is prevented from entering the interior by capillary action.
[0012]
Furthermore, the metal molded roof tile A of the present invention is characterized by the following measures. In the metal molded roof tile A, the width of the lower surface mountain portion 21a on the lower surface 21 of the engaging portion is formed smaller than a predetermined width. That is, when the width of the lower surface valley portion 21b of the engagement portion lower surface 21 is used as a reference, the width of the lower surface peak portion 21a is narrower. When the width of the lower surface valley portion 21b of the engaging portion lower surface 21 at least at a position where the lower surface valley portion 21b is combined with the suspender B fixing the metal molded roof tile A installed on the lower step is set to a predetermined width, The width of the lower surface 21 of the engaging portion other than the above is formed narrower than a predetermined width. That is, in the lower surface valley portion 21b, the width of the other engaging portion lower surface 21 is narrower at least on the basis of the width (width in the eaves-ridge direction) of the portion on which the suspension B is covered. is there. In other words, the wide portion may be at least a portion to be combined with the hook B.
[0013]
The metal-molded roof tile A of the present invention is manufactured by press-molding a metal plate. At this time, in the cut shape of the metal plate to be pressed, the width of the lower surface mountain portion 21a of the lower surface 21 of the engaging portion and the lower surface valley portion 21b The width of the lower surface mountain portion 21a is made narrower without making the width of the lower portion the same. The wide portion serving as a reference is a portion combined with the hangers B at least in the bottom valley portion 21b, and the width is the width of the portion on which the hangers B are covered in the eaves-ridge direction.
If the width is the same, as described above, when press molding, the vicinity of the top of the peak 4 is folded down, and at the point where the metal plate is most likely to shrink, wrinkles are close to the fabric. When the metal plate is bent to form the lower surface 21 of the engagement portion, the metal plate spreads and becomes wavy, and conversely, the peak portion 4 and the valley portion 5 where the metal plate is likely to extend are formed. At the border, the phenomenon that cracks occur in the process occurs, and it does not become a mountain part 4 that draws a beautiful radius, it does not draw a beautiful curved surface with the specified dimensions, it will not be able to be a product . In particular, since the folded portion of the engaging portion 2 on the eaves side is not a hidden portion, a defective shape must not be exposed over the entire roof surface.
[0014]
As described above, even if the width of the lower surface mountain portion 21a on the lower surface 21 of the engaging portion is smaller than the predetermined width, the width of the lower surface valley portion 21b on the lower surface 21 of the engaging portion is at least a portion combined with the hook B. It is a predetermined width. For this reason, the hook B is put on the concave portion 12 of the upper surface 11 of the engaging portion, and when the engaging portion 2 of the metal-molded roof tile A to be installed on the upper stage is combined therewith, the lower surface 21 of the engaging portion The width of the lower surface valley portion 21b is a sufficient width, and the strength can be maintained. In addition, the goby-assembled portion of the lower valley portion 21b and the upper valley portion 11b may be infiltrated by rainwater, but if the portion of the hook B of the lower valley portion 21b is wide at least, the hooks are deeply engaged. Even if rainwater infiltrates from the lower side of the lower surface valley portion 21b by going back to the face plate portion 3, it does not easily enter the inside. Since the width of the lower valley portion 21b is a predetermined width and can be firmly combined with the suspender B fixing the metal-molded roof tile A installed in the lower step, extremely speaking of the lower ridge portion 21a The width may be such a degree that the end face is folded so that the cut end is not visible.
[0015]
A state in which such a metal-molded roof tile A is constructed by using the hangers B will be described with reference to FIG. 13. First, an embodiment of the hangers B will be described. The hanging member B shown in FIG. 13 has a fixing surface B1, an upright portion B2 having one side of the fixing surface B1 raised substantially at a right angle, and an upper edge of the upright portion B2 in a direction opposite to the fixing surface B1. It has a plane portion B3 bent at a substantially right angle and a folded portion B4 obtained by folding the plane portion B3. In the case of the present embodiment, the folded-down portion B4 is folded stepwise to increase the strength, and the lower edge thereof is folded inward at a substantially right angle. It is preferable to make a hole in the fixing surface B1 in advance.
[0016]
The hanging member B having such a configuration is put on the concave portion 12 of the locking portion upper surface 11 of the metal-molded roof tile A, and the fixing surface B1 is fixed to a base material (not shown) with a fastener. Then, the engaging portion 2 of the metal-molded tile A to be constructed on the upper level is put on the folded-down portion B4 of the suspension B fixing the metal-shaped tile A to be constructed on the lower level. To the locking part 1. In other words, the lower valley portion 21b is formed on the upper valley portion 11b, and the lower ridge portion 21a is formed on the upper ridge portion 11a.
The left and right metal molded roof tiles A and A are installed on the mountain 4 (the right side in FIG. 2) on the side where the groove portion 41 is present in the metal molded roof tiles A already installed. The ridges 4 (the ridges 4 on the side without the groove portion 41, the left side in FIG. 2) are overlapped. Then, the metal-molded roof tile A is moved from the eaves side to the ridge side, and the locking portions 1.1 are connected to each other. This is performed by combining the engaging portions 2.
[0017]
If the metal-molded roof tile A and the hangers B of the present embodiment are used, the concave portion 12 allows the construction without affecting the thickness of the hangers B on the surface of the metal-molded roof tiles A. Further, since the groove portion 41 is formed, even if rainwater enters as if blowing up from a gap between the combined portions of the face plate portions 3 of the metal molded roof tiles A, the water enters the interior due to the capillary phenomenon. Is preventing.
Further, as illustrated in detail in FIGS. 10 and 11, the engaging portion 2 on the right side and the eaves side toward the metal molded roof tile A in FIG. 2 is formed by being retracted toward the ridge side. The locking portion 1 on the left side and on the ridge side is formed to be retracted toward the eaves side. For this reason, when the engaging portions 2.2 of the metal molding roof tiles A adjacent to each other on the left and right and the locking portions 1.1 are combined, the eaves side are not aligned, and are aligned substantially in a straight line. It is possible to maintain a sense of unity without compromising the quality, and it is difficult for rainwater to enter through gaps.
In addition, the shape of the engaging portion 2 and the locking portion 1 is substantially U-shaped in cross section, so that they have strength. When is lifted by the wind, the lower edge of the folded-down portion 4B can press the inside (back side) of the lower surface 21 of the engaging portion from above, so that the strength can be further maintained.
[0018]
【The invention's effect】
The peaks of conventional metal-molded roof tiles were flat at the top, and no attempt was made to form a mountain that draws a beautiful curved surface; instead, a round roof part had to be covered. However, according to the metal-molded roof tile of the present invention, the width of the ridge is formed to be smaller than the predetermined width on the lower surface of the engaging portion, so that a clean curved ridge can be formed.
