The present invention is a metal fitting type folded plate roofing material, and in particular, it is possible to easily and quickly connect the ends of adjacent roofing materials with a goose joint to perform roofing construction. Further, the present invention relates to a fitting-type folded plate roofing material that has a smart appearance when roofed and has a good joint strength at the gouge-tightening fitting portion.
工場や倉庫、店舗等への屋根葺きの方法としては、従来、屋根下地(梁)上に一定の間隔で固定されている屋根受金具(タイトフレーム)を介して、幅方向の一方の側縁部に形成された内ハゼ側嵌合部(下ハゼ)を設けて形成された一の金属製折板屋根材と、この屋根材の幅方向の他方の側縁部に形成された外ハゼ側嵌合部(上ハゼ)を設けて形成された隣接する他の屋根材とをハゼ継ぎし、該金属製折板屋根材同士を順次に接続して、ボルトレス状態(嵌合式)にて屋根の葺き上げを行う施工方法が知られている(特許文献1、2)。
As a method of roofing to factories, warehouses, stores, etc., one side edge in the width direction is conventionally connected via a roof bracket (tight frame) fixed at a certain interval on the roof base (beam). One metal folded-plate roof material formed by providing an inner goby side fitting part (lower goby) formed in the part, and the outer gore side formed at the other side edge in the width direction of the roof material Connect the other roof materials adjacent to each other formed by providing the fitting part (upper seam), connect the metal folded plate roof materials in sequence, and connect the roof in the boltless state (fitting type). A construction method for carrying out lifting is known (Patent Documents 1 and 2).
従来のこのような嵌合式折板屋根材としては、内・外ハゼ側嵌合部が、逆L字形状の角ハゼ(特許文献1)、略円弧状の丸ハゼ(特許文献2)、略三角形状の三角形ハゼからなるものがある。
As such conventional fitting type folded plate roofing materials, the inner / outer goby side fitting portion has an inverted L-shaped square goby (Patent Document 1), an approximately arc-shaped round goby (Patent Document 2), and an approximately Some are made of triangular goby.
しかしながら、特許文献1の屋根材では、主板部に風の吹き上げによる上向きの圧力が生じた場合に、内ハゼ側嵌合部(逆L字)および外ハゼ側嵌合部のいずれか少なくとも一方に、風圧などに起因した回転モーメントがかかる。これにより、ハゼ締め嵌合部が簡単に外れたり、また、作業者が屋根の上を歩くときに下向きの圧力がかかった場合にも、そのハゼ締め嵌合部が弛んだり、外れたりする問題があった。
However, in the roof material of Patent Document 1, when upward pressure is generated in the main plate portion due to wind blowing up, at least one of the inner goby side fitting portion (reverse L-shape) and the outer gouge side fitting portion is used. Rotational moment is caused by wind pressure. As a result, the gouge-tightening fitting part can be easily detached, and when the operator applies downward pressure when walking on the roof, the gouge-tightening fitting part loosens or comes off. was there.
また、特許文献2の折板型屋根材では、屋根材同士の接合部である内・外ハゼ側嵌合部の構造が円形断面の嵌合構造からなり、嵌合後は風の吹き上げによる負圧や、作業者の歩行等による押圧力に対して安定した強度を有する。しかし、ハゼ締め加工性が良いとは言えず、ハゼ締め加工時に外ハゼ側嵌合部頂部の曲げ位置が不揃いになりやすいことや、締め付け力が弱く、嵌合部頂部の外観上の直進性が失われやすいという解決すべき課題が残っていた。
Moreover, in the folded-plate roof material of patent document 2, the structure of the inner / outer goby side fitting part which is a junction part of roof materials consists of a fitting structure of a circular cross section, and after fitting, it is negative by wind blowing up. It has stable strength against pressure and pressing force caused by workers walking. However, it cannot be said that the seam tightening processability is good, the bending position of the top part of the outer gore side fitting part tends to be uneven during the gore fastening process, the tightening force is weak, and the straightness on the appearance of the top part of the fitting part There remains a problem to be solved that is easily lost.
即ち、特許文献2の従来の折板屋根材では、外ハゼ側嵌合部頂部の曲げ位置が一定にならない場合(例えば、図13に示すように、外ハゼの通り芯が中心よりも右側(図13(a))または左側(図13(b))に寄った場合)、ハゼ締め強度が低下するという問題があった。
That is, in the conventional folded-plate roof material of patent document 2, when the bending position of the outer goby side fitting part top part is not constant (For example, as shown in FIG. 13 (a)) or on the left side (in the case of FIG. 13 (b)), there is a problem that the goat fastening strength is lowered.
さらに、特許文献2の従来の折板屋根材については、内・外ハゼ側嵌合部が、三角形ハゼからなる場合には、ハゼ締め加工が容易で、強固に嵌合し、嵌合後は風圧に対して安定した強度を有する。しかし、外ハゼ側嵌合部の頂部の折れ目(折れ線)がシャープな形状になるため、既設屋根下地やタイトフレームの歪みに対応させ難く、嵌合部頂部の外観上の直進性や形状精度が悪いという問題があった。
Furthermore, with respect to the conventional folded plate roof material of Patent Document 2, when the inner / outer goby side fitting portion is made of a triangle goby, the gouge fastening process is easy and tightly fitted, and after fitting, Has stable strength against wind pressure. However, the crease (folded line) at the top of the outer goby side fitting part has a sharp shape, making it difficult to cope with distortion of the existing roof base and tight frame, and straightness and shape accuracy on the appearance of the fitting part top There was a problem of being bad.
また、折板屋根材に使われる金属板は、一般に、原板幅に許容差(最大余幅7mm)があり、その誤差を、金属板の両側縁部に形成される内ハゼ側嵌合部および外ハゼ側嵌合部で吸収することになっている。そのため、嵌合部の形状が金属板毎に変化してしまい、内ハゼ側嵌合部と外ハゼ側嵌合部とを確実に嵌着させることができないという問題もあった。
In addition, the metal plate used for the folded plate roofing material generally has a tolerance in the original plate width (maximum extra width 7 mm), and the error is compensated for by the internal goby side fitting portion formed on both side edges of the metal plate and It is to be absorbed by the outer goby side fitting part. For this reason, the shape of the fitting portion changes for each metal plate, and there is also a problem that the inner goby side fitting portion and the outer gouge side fitting portion cannot be securely fitted.
なお、このような嵌合式屋根材の施工工事では、施工時に外側からハゼ締め嵌合状態の良し悪しを判別しづらいため、屋根板のハゼ締め嵌合構造、例えば内・外ハゼ側嵌合部の形状をどのようにするかは、極めて重要なことである。
In addition, in construction work of such a fitting type roofing material, it is difficult to determine whether the gouge tightening fit state is good or bad from the outside at the time of construction. It is extremely important to determine the shape of the.
上述した従来技術の場合、本発明の対象であるボルトレス施工式の屋根の場合に見られる、屋根材の浮き上がり、即ち、風圧に起因する屋根材の浮き上がりが発生し易いこと、あるいは、ハゼ締め嵌合部の弛みや外れが起こりやすいこと(特許文献1)、また、ハゼ締め加工(電動シーマ加工)性や、稜線(嵌合部頂部)の直進性即ち屋根葺き外観の仕上がりについて改善の余地があること(特許文献2)、さらには内・外ハゼ側嵌合部の形状精度が悪いことや、曲げ剛性が小さく、特に受金具(タイトフレーム)のない個所における結合力が悪いことなどが指摘されていた。
In the case of the above-described prior art, the roof material is lifted, that is, the roof material is likely to be lifted due to wind pressure, as seen in the case of the boltless construction type roof which is the object of the present invention, or the gouge is fastened. There is room for improvement with respect to the ease of loosening and disengagement of joints (Patent Document 1), goat fastening (electric seam processing), straightness of the ridgeline (fitting part top), that is, the finish of the roofing appearance. It is pointed out that there is a certain (Patent Document 2), and that the shape accuracy of the inner / outer goby side fitting part is poor, the bending rigidity is small, especially the coupling force at the place where there is no bracket (tight frame), etc. It had been.
そこで、本発明は、ハゼ継ぎ嵌合部を持たない山部を加えた複数(3以上)の山部を形成すると共に、内ハゼ側嵌合部ならびに外ハゼ側嵌合部による互いの結合力を向上させた構造とすることにより、風の吹き上げ圧力に対する耐風圧強度に優れる他、作業者の踏み込み等による押圧によってもハゼ締め嵌合部に弛みや外れが生じるようなことをなくすことができ、また、高いハゼ締め効果を有する嵌合式折板屋根材を提供することを目的とする。
Therefore, the present invention forms a plurality of (three or more) ridges including a ridge that does not have a goat joint fitting portion, and the mutual coupling force by the inner gobe side fitting portion and the outer goze side fitting portion. In addition to being excellent in wind pressure resistance against wind blowing pressure, it is possible to eliminate loosening and disengagement in the gouge-tightening fitting part due to pressing by the operator's stepping on etc. Moreover, it aims at providing the fitting type folded-plate roof material which has a high goat fastening effect.
また、本発明は、金属板の原板幅の誤差に左右されることなく、内・外ハゼ側嵌合部の形状精度に優れると共にハゼ締め加工の作業性にも優れ、かつハゼ締め後の外観形状も綺麗で、簡単かつ迅速に屋根葺きの施工を行うことのできる嵌合式折板屋根材を提供することを目的とする。
In addition, the present invention is not affected by the error in the width of the original plate of the metal plate, is excellent in the shape accuracy of the inner / outer goby side fitting portion and is excellent in the workability of the gouge fastening process, and the appearance after the gouge fastening The object is to provide a fitting type folded plate roofing material that has a beautiful shape and can be easily and quickly constructed.

上述した構成を採用した本発明の場合、次のような効果が期待できる。
(1)ハゼ継ぎ山部の他に非ハゼ継ぎ山部を形成したので、基本的には山の数が増える分だけ、同じ働き幅で山の間隔(受金具の間隔)を狭くすることができる。その結果、屋根板の単位面積当たりの耐風圧強度が相対的に大きくなり、強風に対する安全性が増大する。 In the case of the present invention employing the above-described configuration, the following effects can be expected.
(1) Since the non-haze seam portion is formed in addition to the seam seam portion, it is basically possible to reduce the mountain spacing (interval of the metal fittings) with the same working width as much as the number of mountains increases. it can. As a result, the wind pressure strength per unit area of the roof panel is relatively increased, and the safety against strong wind is increased.
(1)ハゼ継ぎ山部の他に非ハゼ継ぎ山部を形成したので、基本的には山の数が増える分だけ、同じ働き幅で山の間隔(受金具の間隔)を狭くすることができる。その結果、屋根板の単位面積当たりの耐風圧強度が相対的に大きくなり、強風に対する安全性が増大する。 In the case of the present invention employing the above-described configuration, the following effects can be expected.
(1) Since the non-haze seam portion is formed in addition to the seam seam portion, it is basically possible to reduce the mountain spacing (interval of the metal fittings) with the same working width as much as the number of mountains increases. it can. As a result, the wind pressure strength per unit area of the roof panel is relatively increased, and the safety against strong wind is increased.
(2)同じ原板幅(762mm、914mm等)の場合、山の数が増えると全体的には山高さを低く抑えることができる。したがって、施工対象が小屋や車庫などの屋根の場合にも使えるようになるので、屋根に対する要望や規模に応じた多様なデザインのものを経済的に製作、施工することができる。
(2) In the case of the same original plate width (762 mm, 914 mm, etc.), if the number of peaks increases, the peak height can be kept low overall. Therefore, since it can be used even when the construction object is a roof such as a hut or a garage, it is possible to economically produce and construct various designs according to the demand and scale of the roof.
(3)非ハゼ継ぎ山部を設けることで、ハゼ締め加工が不要になる分、施工が容易になる。また、さらにハゼ締め前(通常、屋根材を仮固定した後、まとめてハゼ締め機によりハゼ締めを行う)の仮固定時における単位面積当たりの耐風圧強度が増加するので、施工途中の強風に対する安全性が向上する。
(3) By providing the non-haze seam portion, the construction is facilitated by the amount that the gore-fastening process is unnecessary. In addition, since the wind pressure resistance per unit area at the time of temporary fixing before the tightening (usually after the roofing material is temporarily fixed and then collectively tightened with a gore fastening machine) is increased, Safety is improved.
(4)非ハゼ継ぎ山部の頂部に擬似ハゼ状の踏込み突条を設けたので、この突条の踏み込みによる口開き作用により、受金具への嵌着が容易になり、施工が簡単で能率が上がる。また、これらの突条の付加は、折板屋根に統一されたデザイン性を付与し、一方でこれを省略した場合は外観に変化を与える。したがって、いずれの場合にも、デザイン性が向上する。
(4) Since a pseudo-haze-shaped stepping ridge is provided at the top of the non-haze joint, the opening action by stepping on the ridge makes it easy to fit into the bracket, making installation simple and efficient. Goes up. Moreover, the addition of these ridges gives a unified design to the folded-plate roof. On the other hand, if this is omitted, the appearance is changed. Therefore, in any case, the design is improved.
(5)外ハゼ側嵌合部を茸形とし、内ハゼ側嵌合部を傘形としたハゼ締め嵌合構造としたことにより、風の吹き上げや作業者の踏み込み等によって屋根板の左右どちらに圧力がかかったとしても、内ハゼ側嵌合部と外ハゼ側嵌合部とが、左右両側部に設けられた張り出し部において互いにぶつかり合い、屋根板の回転が拘束される。従って、この屋根材の場合、風の吹き上げによる負圧や作業者の踏み込み等による押圧力がかかっても、この屋根材が回転してハゼ締め嵌合状態が簡単に弛んだり、外れたりするようなことがなくなる。これにより雨の侵入を効果的に防ぐことができる。
(5) By adopting a gouge-tightened fitting structure with the outer gobe side fitting part as a bowl and the inner goat side fitting part as an umbrella shape, Even if pressure is applied, the inner goby side fitting portion and the outer gobe side fitting portion collide with each other at the overhang portions provided on the left and right side portions, and the rotation of the roof plate is restricted. Therefore, in the case of this roofing material, even if a negative pressure due to wind blowing or a pressing force due to an operator stepping on is applied, the roofing material rotates and the gouge tightening fitting state is easily loosened or detached. There is nothing wrong. This effectively prevents rain from entering.
(6)外ハゼ側嵌合部のドーム形頭部の頂部に予め凸条部からなる折り線を設けたので、ハゼ締め加工(シーマ加工)が容易で、稜線(尾根)の直進性(通り芯)が高く、屋根下地やタイトフレームの歪みに起因する稜線の通り芯のずれを外観上見え難くすることができ、屋根葺き外観形状が綺麗に仕上がる。
(6) Since a fold line consisting of a ridge is provided in advance on the top of the dome-shaped head of the outer goby side fitting part, goat fastening (seaming) is easy, and straightness of the ridge (ridge) (street) The core) is high, and the misalignment of the core along the ridge line caused by the distortion of the roof base and tight frame can be made difficult to see on the appearance, and the roofing appearance shape is finished beautifully.
(7)内・外ハゼ側嵌合部によるハゼ締め嵌合状態の結合力が強く、しかも内ハゼ側嵌合部に折返し重畳部を具えるので、内ハゼ側嵌合部の形状精度が高く、ハゼ締め後の形状安定性および接合力に優れる。
(7) Since the inner / outer side fitting part has a strong coupling force in the gouge tightening fitting state, and the inner goat side fitting part is provided with a folded overlap part, the shape accuracy of the inner goat side fitting part is high. Excellent shape stability and bonding strength after gouge fastening.
(8)底部からの立上がり側板を傾斜させ、かつ1以上の小段差を設けたことにより、側板の曲げ剛性を向上させることができると共に、日射熱等に起因する屋根板波打ち現象に伴う音鳴りの発生を抑制することができる。
(8) By tilting the side plate rising from the bottom and providing one or more small steps, it is possible to improve the bending rigidity of the side plate and to generate a sound due to the roof plate undulation phenomenon caused by solar heat etc. Can be suppressed.
(9)底部に隣接する側板下端の曲げ始め位置に、底部側に凹んだ大段差を設けたことにより、底部の圧縮強度が向上し、風の吹き上げ圧力に対する屋根板の耐風圧強度を向上させることができる。
(9) By providing a large step recessed on the bottom side at the bending start position of the lower end of the side plate adjacent to the bottom, the compressive strength of the bottom is improved, and the wind pressure resistance of the roof plate against the wind blowing pressure is improved. be able to.
(10)水平部に隣接する側板上端に底部側に窪んだ張り出し凹部を受金具(タイトフレーム)の爪片に係止させるようにしたので、風の吹き上げ圧力に対する屋根板と受金具(タイドフレーム)の接合強度を向上させることができる。
(10) Since the overhanging recess recessed to the bottom side is locked to the claw piece of the receiving metal fitting (tight frame) at the upper end of the side plate adjacent to the horizontal portion, the roof plate and the receiving metal fitting (tide frame) against the wind blowing pressure ) Can be improved.
以下にまず、本発明の基本的な構成について、代表的な実施形態を挙げて説明する。また、本明細書において、本実施形態の屋根板の形状および構造の説明は、主に屋根材の正面から見た縦断面形状に基づいて述べる。実際の屋根板は、縦方向(垂木方向)に延びる条状の形をなす。
First, the basic configuration of the present invention will be described with reference to typical embodiments. Moreover, in this specification, description of the shape and structure of the roof board of this embodiment is mainly described based on the longitudinal cross-sectional shape seen from the front of the roof material. The actual roof plate has a strip shape extending in the vertical direction (the rafter direction).
図1は、本発明に係る嵌合式折板屋根材の代表的な実施形態を示すものである。ここに例示するものは、矩形状金属板の幅方向(桁材方向)を略角波形に屈曲成形したものであって、幅方向両端部にそれぞれ、ハゼ継ぎ山部M1、M1’が屈曲成形(造形)されており、これらのハゼ継ぎ山部M1、M1’の間には、1以上複数個(ただし、この図示例は1個)の非ハゼ継ぎ山部M2が、略平坦な底部1を介在した状態で連続的な屈曲成形によって連設されている。これらの山部M1~M2は、その山裾の部分、即ち、前記底部1の両側端からそれぞれ斜め上方に起立させた傾斜側板部2が連設されており、さらに、これらの傾斜側板部2のそれぞれの上端部からは、水平方向もしくは若干上向き傾斜した略水平方向に張り出した水平部3、3’を連設して頂部とし、全体として台形状の山形を形造っている。
FIG. 1 shows a typical embodiment of a fitting type folded plate roof material according to the present invention. In this example, the rectangular metal plate is formed by bending the width direction (beam direction) into a substantially square waveform, and the seam joints M1 and M1 ′ are bent at both ends in the width direction. Between these goat joints M1 and M1 ′, one or more (however, in the illustrated example, one) non-haze joints M2 are substantially flat bottom 1 Are continuously arranged by bending. These ridges M1 and M2 are connected with inclined side plate portions 2 that stand up diagonally upward from both sides of the bottom portion 1, that is, both side ends of the bottom portion 1. Further, the inclined side plate portions 2 From each upper end portion, horizontal portions 3 and 3 'projecting in the horizontal direction or in a substantially horizontal direction inclined slightly upward are connected to form a top portion, and a trapezoidal chevron is formed as a whole.
そして、水平部3が設けられているハゼ継ぎ山部M1、M1’については、その遊端部に、後で詳述する外ハゼ側嵌合部4もしくは内ハゼ側嵌合部5のいずれかがそれぞれ連設される。一方、非ハゼ継ぎ山部M2については、ハゼ継ぎ構造を全く持たない図2に示すような、擬似ハゼ状の踏込み突条8が突設される。この踏込み突条8は、ハゼ継ぎに用いられるものではなく、他の目的をもつ。
And about the goby joint part M1 and M1 'in which the horizontal part 3 is provided, the outer end side fitting part 4 or the inner goat side fitting part 5 which will be described in detail later is provided at the free end part thereof. Are connected to each other. On the other hand, as for the non-haze seam portion M2, a pseudo-haze-like stepping ridge 8 as shown in FIG. The step ridge 8 is not used for the seam joint and has another purpose.
なお、本実施形態の屋根材は、一の屋根板の内ハゼ側嵌合部5に対し、後述する受金具を介して他の屋根板の外ハゼ側嵌合部4を上から被せて嵌合することで順次につなぎ合わせ、隣接する屋根材同士を幅方向に、ボルトレス施工方式により屋根葺きされるものである。
In addition, the roofing material of the present embodiment is fitted to the inner goby side fitting portion 5 of one roof plate by covering the outer gobe side fitting portion 4 of the other roof plate from above via a metal fitting described later. By joining together, the adjacent roofing materials are roofed by the boltless construction method in the width direction.
本発明においては、このように、金属板幅方向の両端部に一対のハゼ継ぎ山部M1、M1’を設けると共に、これらの間にはそれぞれ略平坦形状の底部を介して非ハゼ継ぎ山部M2(ただし、これらは後述する受金具の山6aならびに爪7、7’に対応して設けられる)を1以上連設しているので、耐風圧強度が向上するだけでなく、山高さを抑えて適用対象を拡げることができ、さらにはハゼ継ぎ作業を一部省略することができるので、施工の作業性が向上する。
In the present invention, a pair of goby joints M1 and M1 ′ are provided at both ends in the width direction of the metal plate as described above, and a non-goat joint is provided between the two via a substantially flat bottom. Since one or more M2s (however, these are provided to correspond to the later described receiving metal peaks 6a and claws 7, 7 '), not only the wind pressure strength is improved but also the height of the peaks is suppressed. Thus, the application range can be expanded, and furthermore, part of the seam joining work can be omitted, so that the workability of construction is improved.
とくに、図2に示すような非ハゼ継ぎ山部M2については、ハゼ継ぎ時に受金具6に対して取付けができるハゼ継ぎ山部M1、M1’とは異なり、ハゼ継ぎ部がないため、受金具6の頂部6aに対し、上から足で踏み込み押圧することによってのみ、取付けが可能になるものである。このことは、図5等に示される受金具6の爪片7、7’に係止させる際に、該ハゼ継ぎ山部M2を上からより強く押圧する必要があることを意味しており、労働負荷が大きくなる。この点、図2ならびに図8、図9に示すように、水平部3’上に前記擬似ハゼ状踏込み突条8が形成されている。突条8を上から足で強く踏み込むだけで、前記傾斜側板部2を設けたことが相俟って、該非ハゼ継ぎ山部M2の下向きに拡開する口開き作用が助長されることになって、嵌め込みが一層容易になり、屋根葺き施工が簡単確実に達成される。
In particular, the non-haze joint portion M2 as shown in FIG. 2 is different from the goose joint portions M1 and M1 ′ that can be attached to the fitting 6 at the time of joining, so there is no gouge joint portion. 6 can be attached only by stepping on the top 6a of the foot 6 with a foot and pressing it. This means that it is necessary to press the gob joint portion M2 more strongly from above when engaging with the claw pieces 7 and 7 ′ of the metal fitting 6 shown in FIG. Labor load increases. In this regard, as shown in FIGS. 2, 8, and 9, the pseudo goby stepping protrusion 8 is formed on the horizontal portion 3 ′. By simply stepping on the ridge 8 with a foot from above, the provision of the inclined side plate portion 2 helps the mouth opening action of expanding the non-haze seam portion M2 downward. Thus, the fitting is further facilitated, and the roofing construction can be achieved easily and reliably.
本実施形態の屋根材における特徴的な構成の1つは、外ハゼ側嵌合部4および内ハゼ側嵌合部5の断面形状、およびこれらのハゼ締め加工後の嵌合構造にある。そこでまず、外ハゼ側嵌合部4の構造について説明する。外ハゼ側嵌合部4の構造は、図3に示すように、屋根の傾斜側板部2から張り出した水平部(略水平のものも含む)3の遊端部の位置にあって、ハゼ締め加工前の状態が略垂直に立ち上がる底部側脚部としての右脚部4aと、その右脚部4aの上端部に連設されたドーム形頭部4bと、この頭部4bの延長上に、ハゼ締め加工後に内ハゼ側嵌合部5の脚部5aに沿うように延在される側端部側脚部としての左脚部4cとを連設して形成される。外ハゼ側嵌合部4の断面形状は略茸形を呈し、内ハゼ側嵌合部5全体を包囲するように被せたのちハゼ締めして用いられる。ここで、ドーム形頭部4bの頂部には、図4に示すように、折れ曲がりの起点となるべき、他の部分とは曲率の異なる(曲率半径の小さい)部分4dが、その幅方向両側の他の(曲率半径の大きい)部分に対し滑らかに連なるように形成してある。
One of the characteristic structures in the roofing material of the present embodiment is the cross-sectional shape of the outer goby side fitting portion 4 and the inner gobe side fitting portion 5, and the fitting structure after these gouge fastening processes. First, the structure of the outer goby side fitting portion 4 will be described. As shown in FIG. 3, the structure of the outer goby side fitting portion 4 is located at the free end portion of the horizontal portion (including a substantially horizontal one) 3 protruding from the inclined side plate portion 2 of the roof. On the right leg 4a as the bottom side leg that rises substantially vertically before processing, the dome-shaped head 4b connected to the upper end of the right leg 4a, and the extension of the head 4b, It is formed by connecting a left leg portion 4c as a side end portion side leg portion extending along the leg portion 5a of the inner goat side fitting portion 5 after the gouge fastening process. The cross-sectional shape of the outer goby side fitting portion 4 is substantially bowl-shaped, and is used after being covered so as to surround the entire inner goze side fitting portion 5 and then being gouge-tightened. Here, at the top of the dome-shaped head 4b, as shown in FIG. 4, there are portions 4d that have different curvatures (small curvature radii) from the other portions, which should be the starting points of bending, on both sides in the width direction. It is formed so as to be smoothly connected to other parts (having a large radius of curvature).
これに対し、内ハゼ側嵌合部5は、図3に示すように、前記傾斜側板部2から張り出した水平部3の遊端部の位置にあって、略垂直に立ち上がる脚部5aと、その脚部5aの上端部に連設して形成された山形頭部5bとから形成され、全体の断面形状が略傘形を呈するものである。
On the other hand, as shown in FIG. 3, the inner goby side fitting portion 5 is located at the free end portion of the horizontal portion 3 protruding from the inclined side plate portion 2, and a leg portion 5 a that rises substantially vertically, It is formed from a mountain-shaped head 5b formed continuously with the upper end of the leg 5a, and the entire cross-sectional shape has a substantially umbrella shape.
この実施形態の屋根材によれば、図3に示すように、外ハゼ側嵌合部4を内ハゼ側嵌合部5の上に被せた後、外ハゼ側嵌合部4の左脚部4cを、点線で示した位置から実線で示す位置まで押し下げ、左脚部4cによって内側に位置する内ハゼ側嵌合部5の脚部5aを締め付けることにより、強固なハゼ締め加工をすることができる。
According to the roofing material of this embodiment, as shown in FIG. 3, the outer leg side fitting portion 4 is placed on the inner goby side fitting portion 5, and then the left leg portion of the outer goby side fitting portion 4. 4c is pushed down from the position indicated by the dotted line to the position indicated by the solid line, and the leg portion 5a of the inner goby side fitting portion 5 located on the inner side is tightened by the left leg portion 4c, thereby performing a strong gouge fastening process. it can.
すなわち、本実施形態では、図に矢印で示したような方向に、風の吹き上げ等による負圧が、屋根板の左右どちらにかかったとしても、あるいは作業者の踏み込み等による押圧力が屋根板の左右どちらにかかったとしても、外ハゼ側嵌合部4のドーム形頭部4b下端の左右張り出し部4e、4e’と、内ハゼ側嵌合部5の山形頭部5b下端の左右張り出し部5d、5d’とが互いにぶつかり合い、屋根板の回転が拘束されることになり、嵌合状態が弛んだり、外れるのを防ぐことができる。
That is, in this embodiment, whether the negative pressure due to wind blowing or the like is applied to the left or right of the roof plate in the direction indicated by the arrow in the figure, or the pressing force due to the operator's stepping or the like is applied to the roof plate. The right and left overhanging portions 4e and 4e 'at the lower end of the dome-shaped head portion 4b of the outer goat side fitting portion 4 and the left and right overhanging portion at the lower end of the angle head portion 5b of the inner goat side fitting portion 5 5d and 5d ′ collide with each other, and the rotation of the roof plate is restricted, so that the fitting state can be prevented from loosening or coming off.
なお、この内ハゼ側嵌合部5は、非脚部側すなわち遊端部側が下面に折り返して重ね合わせてなる折り返し重畳部5cが形成されている。これにより、山形頭部5bを補強することができ、ハゼ締め加工時の変形を抑えて形状の精度が向上するとともに、原板幅の許容差(誤差)を、この折り返し重畳部5cによって吸収することができる。そのため、内ハゼ側嵌合部5を常に同じ形状に永く維持することができる。即ち、内ハゼ側嵌合部5と外ハゼ側嵌合部4とを強固に嵌着させることができるようになる。なお、この折り返し重畳部5cは、図3、図4に示すように、内ハゼ側嵌合部5の下面側に折り返す他、内ハゼ側嵌合部5の上面側に折り返してもよい。
The inner goat side fitting portion 5 is formed with a folded overlap portion 5c in which the non-leg portion side, that is, the free end portion side is folded back and overlapped. Thereby, the chevron head 5b can be reinforced, the deformation at the time of the gouge tightening process is suppressed, the accuracy of the shape is improved, and the tolerance (error) of the original plate width is absorbed by the folded overlap portion 5c. Can do. Therefore, the inner goby side fitting part 5 can always be kept long in the same shape. That is, the inner goby side fitting part 5 and the outer gobe side fitting part 4 can be firmly fitted. In addition, as shown in FIG. 3 and FIG. 4, the folded overlap portion 5 c may be folded back to the upper surface side of the inner goat side fitting portion 5 in addition to being folded back to the lower surface side of the inner goby side fitting portion 5.
また、水平部3は、底部1側に向ってわずかに下向きに傾斜していることが好ましい。これにより、内ハゼ側嵌合部5と外ハゼ側嵌合部4とのハゼ締め嵌合部に水が浸入するのを防ぐ効果が向上する。
Further, it is preferable that the horizontal portion 3 is inclined slightly downward toward the bottom portion 1 side. Thereby, the effect which prevents water permeating into the gourd fastening fitting part of the inner goby side fitting part 5 and the outer goby side fitting part 4 is improved.
次に、図4は、上記実施形態における外ハゼ側嵌合部4および内ハゼ側嵌合部5の一変形例を示すものである。この変形例では、外ハゼ側嵌合部4については、右脚部4a’および左脚部4c’がいずれも水平部3から斜めに立ち上がり、内ハゼ側嵌合部5については、水平部3に連設される脚部5a’が斜めに立ち上がっているところに特徴がある。これにより、脚部を略垂直に立ち上がるように成形した図3の屋根材よりも、外ハゼ側嵌合部4および内ハゼ側嵌合部5として必要とする板幅を少なくすることができ、その分、屋根材の底部1から嵌合部4、5の頂部までの山高を高くすることができる。そのため、屋根材全体の曲げに対する剛性、強度を向上させることができる。
Next, FIG. 4 shows a modified example of the outer goby side fitting part 4 and the inner goat side fitting part 5 in the above embodiment. In this modified example, the outer leg side fitting part 4 has both the right leg part 4a ′ and the left leg part 4c ′ rising obliquely from the horizontal part 3, and the inner leg side fitting part 5 with the horizontal part 3 There is a feature in that the leg portion 5a 'provided in a row stands up diagonally. Thereby, the board width required as the outer goby side fitting part 4 and the inner goat side fitting part 5 can be reduced as compared with the roof material of FIG. 3 formed so that the legs rise substantially vertically, Accordingly, the mountain height from the bottom 1 of the roofing material to the top of the fitting portions 4 and 5 can be increased. Therefore, the rigidity and strength against bending of the entire roofing material can be improved.
また、外ハゼ側嵌合部4のドーム形頭部4bには、その頂部に折れ曲がりの起点となるべき、他の部分とは曲率の異なる(曲率半径の小さい)部分、即ち凸条部からなる折り線4dが形成してある。折り線4dを設けることで、該外ハゼ側嵌合部4は、ハゼ締め加工時に折れ曲がり始め位置がより明確に特定されて、成形がしやすくなると同時に、稜線(尾根)のばらつきがなくなる。また、屋根下地(梁材)やタイトフレームが不揃いで多少の位置ずれが生じていたとしても、図13に示すような通り芯のずれを外観上見え難くすることができ、屋根葺き状態の外観を美しく仕上げることができる。
Further, the dome-shaped head portion 4b of the outer gore-side fitting portion 4 is composed of a portion having a curvature different from that of the other portion (small radius of curvature), that is, a ridge portion, which should be a starting point of bending at the top. A fold line 4d is formed. By providing the folding line 4d, the outer goat side fitting portion 4 is more clearly identified at the start of bending at the time of the gouge tightening process, can be easily formed, and at the same time, there is no variation in the ridgeline (ridge). Further, even if the roof base (beam material) and tight frame are not uniform and a slight positional shift occurs, it is possible to make the shift of the core as shown in FIG. Can be finished beautifully.
次に、図3の場合と同様に、外ハゼ側嵌合部4と内ハゼ側嵌合部5は、内ハゼ側嵌合部5の上に外ハゼ側嵌合部4を被せた後、外ハゼ側嵌合部4の左脚部4c’を図に点線で示した位置から実線で示した位置まで押し下げ、該左脚部4c’によって内側に位置する内ハゼ側嵌合部5の脚部5aを締め付けることにより、強固にハゼ締めを行うことができる。
Next, as in the case of FIG. 3, the outer goby side fitting portion 4 and the inner gobe side fitting portion 5 are covered with the outer gobe side fitting portion 4 on the inner gouge side fitting portion 5, The left leg portion 4c ′ of the outer goby side fitting portion 4 is pushed down from the position indicated by the dotted line to the position indicated by the solid line in the drawing, and the leg of the inner goat side fitting portion 5 located inside by the left leg portion 4c ′. By tightening the portion 5a, the gouge can be firmly tightened.
図5は、本実施形態の屋根材を、屋根下地に固定された受金具(タイトフレーム)6上に、取り付けた状態を示している。この図から明らかなように、この屋根材の、タイトフレーム6への取り付けは、該タイトフレーム6の両側面頂部6a近傍に突設した爪片7、7’を介して行う。このとき該屋根材の底部1をタイトフレーム6の底部6bに落とし込むと同時に、傾斜側板部2の、水平部3に隣接する上端に設けた張り出し凹部2cに、前記爪片7、7’を係止させる。
FIG. 5 shows a state in which the roof material of the present embodiment is mounted on a receiving metal fitting (tight frame) 6 fixed to the roof base. As is apparent from this figure, the roof material is attached to the tight frame 6 via claw pieces 7 and 7 ′ protruding in the vicinity of the top portions 6 a on both sides of the tight frame 6. At this time, the bottom part 1 of the roof material is dropped into the bottom part 6b of the tight frame 6, and at the same time, the claw pieces 7 and 7 'are engaged with the protruding concave part 2c provided on the upper end of the inclined side plate part 2 adjacent to the horizontal part 3. Stop.
そして、上述の如くして先に取り付けた側の屋根材の内ハゼ側嵌合部5に対し、次に施工する屋根材の外ハゼ側嵌合部4を上から覆い被せるように嵌め入れて結合させる。その後、図示しない電動シーム加工機(シーマー)によって、図3または図4に示すように、外ハゼ側嵌合部4の右脚部4a、左脚部4cをハゼ締め加工することで、外ハゼ側嵌合部4および内ハゼ側嵌合部5は、図3または図4に実線で示したように互いにしっかりと嵌合した状態になる。

なお、図4に示す変形例では、外ハゼ側嵌合部4の右脚部4a’および左脚部4c’と内ハゼ側嵌合部5の脚部5a’とを斜めに立ち上がるように形成している。そのため、一定の原板幅(例えば762mm)を有する金属板を使うときに、嵌合部の脚部を略垂直に立ち上げる屋根材に比べて脚部材が少なくてすむ。そのため、嵌合部の頂部までの山高さを相対的に大きくすることができ、屋根材全体の曲げに対する剛性、強度を向上させることができる。
In the modification shown in FIG. 4, the right leg portion 4 a ′ and the left leg portion 4 c ′ of the outer goby side fitting portion 4 and the leg portion 5 a ′ of the inner goat side fitting portion 5 are formed so as to rise obliquely. is doing. Therefore, when using a metal plate having a constant original plate width (for example, 762 mm), the number of leg members can be reduced as compared with a roofing material in which the legs of the fitting portion are raised substantially vertically. Therefore, the peak height to the top of the fitting portion can be relatively increased, and the rigidity and strength against bending of the entire roofing material can be improved.
