しかし、特許文献１〜特許文献５の取付構造は、折板屋根材の上部のみをタイトフレームに嵌合する嵌合部分としたものであり、施工性は向上するが耐風圧（負圧）強度に関しては問題があった。また、例えば、特許文献６〜特許文献８の取付構造のように折板屋根材の下部（底部）のみをタイトフレームに嵌合し、上部（頂上部）を馳締めによってタイトフレームに固定すると、耐風圧（負圧）強度や接続部の水密機能は向上するが、馳締めのための工具や部品が必要となり工数も増え施工性が悪くなるという問題が生じる。 However, the mounting structure of Patent Literature 1 to Patent Literature 5 is a fitting portion in which only the upper part of the folded plate roof material is fitted to the tight frame, and the workability is improved, but the wind resistance (negative pressure) strength is improved. There was a problem with respect to. Moreover, for example, when the lower part (bottom part) of the folded plate roof material is fitted to the tight frame as in the mounting structures of Patent Documents 6 to 8, and the upper part (top part) is fixed to the tight frame by tightening, Although wind resistance (negative pressure) strength and the watertight function of the connection portion are improved, there is a problem that tools and parts for tightening are required, man-hours are increased, and workability is deteriorated.

すなわち、特許文献１〜特許文献８に示す上記従来の取付構造では、折板屋根材とタイトフレームとの嵌合部分を折板屋根材の上下部いずれか一方に設ける構造としており、そのため、各嵌合部分について強度や水密機能を確保すると施工、即ち嵌合部の嵌め込みが困難となる傾向があり、逆に、施工性の向上を図ると各嵌合部分に強度や水密機能を持たせることができなくなり、両立させようとした場合、嵌合部分の構造が複雑になり部品点数も増加する。 That is, in the conventional mounting structure shown in Patent Literature 1 to Patent Literature 8, the fitting portion between the folded plate roof material and the tight frame is provided on either the upper or lower portion of the folded plate roof material. Ensuring strength and water tightness for the mating part tends to make construction, that is, fitting of the mating part difficult, and conversely, improving workability should give each mating part strength and water tightness. When it becomes impossible to achieve both, the structure of the fitting portion becomes complicated and the number of parts increases.

しかも、隣り合う折板屋根材どうしはすくいかぶせの嵌合により連結されるのが一般的であるが、屋根の構造材の中間部、即ち梁と梁の中間部では、折板屋根材を係止（支持）する為のタイトフレームが無いので、施工時に、折板屋根材のすくいかぶせの連結部のかぶせ側を踏み込むあるいは押し込む時にすくい側が逃げて正常な嵌合が得られ難いという課題がある。そして、嵌合強度と水密性能を重視して、嵌合部のすくい側とかぶせ側のかみ合わせを深くするほど、前記嵌合はより困難となる。 Moreover, it is common for adjacent folded-plate roofing materials to be connected by fitting over a pair of roofs, but in the middle of the roof structural material, that is, between the beams and beams, the folded-plate roofing material is engaged. Since there is no tight frame for stopping (supporting), there is a problem that during construction, the rake side escapes when stepping on or pushing in the covering side of the joint part of the folded roof covering material, and normal fitting is difficult to obtain. . Further, the emphasis is placed on the fitting strength and the watertight performance, and the fitting becomes more difficult as the engagement between the rake side and the covering side of the fitting portion is deepened.

本発明は上述の事柄に留意してなされたもので、その目的は、十分な強度および水密性能を確保するとともに施工性に優れ、梁と梁の中間部においても折板屋根材どうしのすくいかぶせの嵌合が容易となる嵌合式折板屋根材の取付構造を提供することである。 The present invention has been made in consideration of the above-mentioned matters, and its purpose is to ensure sufficient strength and water tightness and excellent workability, and to fold the folded roof material between the beams in the middle of the beams. It is providing the attachment structure of the fitting type folded-plate roof material from which fitting of becomes easy.

上記目的を達成するために、本発明の折板屋根材の取付構造は、屋根の構造材上に立設固定されたタイトフレームに、頂部およびこの頂部の両側から斜め下側に向けて延びる二つの側壁部を備えた山形部と、この山形部の下部に連設され、ほぼ水平に延びる底部とを交互に有する折板屋根材を取り付ける折板屋根材の取付構造であって、隣り合う折板屋根材の少なくとも一方の端の頂部近傍と他方の端の頂部近傍に第一係止部を設け、折板屋根材の底部近傍には第二係止部を形成し、前記タイトフレームには、第一係止部が係止する第一被係止部を備えた第一嵌合部と、第二係止部が係止する第二被係止部を備えた第二嵌合部とを設けて、前記頂部と第一嵌合部、前記底部と第二嵌合部とをそれぞれ嵌合固定してあり、また、隣り合う折板屋根材の一方の端の頂部と他方の端の頂部とをすくいかぶせの嵌合により連結してあり、前記タイトフレームの第一被係止部を、前記すくいかぶせに相対する部分のみに設けてあることを特徴としている（請求項１）。 In order to achieve the above object, a folded plate roof material mounting structure according to the present invention includes a top frame and a two-side structure extending from the both sides of the top portion to a diagonally lower side on a tight frame that is erected and fixed on the roof structural material. A folded plate roof material mounting structure for mounting a folded plate roof material having alternately a chevron portion having two side wall portions and a bottom portion extending in a row and extending substantially horizontally. A first locking portion is provided in the vicinity of the top of at least one end of the plate roof material and in the vicinity of the top of the other end, and a second locking portion is formed in the vicinity of the bottom of the folded plate roof material. A first fitting portion having a first locked portion that the first locking portion locks, and a second fitting portion having a second locked portion that the second locking portion locks. the provided, the top and the first fitting part, Ri the bottom portion and the second fitting portion and the fitted respectively fixed tare, also adjacent Oriban'ya Yes linked by engagement of covered rake a top of the top of one end and the other end of the timber, the first the locked portion of the tight frame is provided only on the portion facing covering the rake (Claim 1).

ここで、前記タイトフレームにほぼ鉛直に起立する壁体が設けられ、この壁体の上端に前記第一被係止部が直接または水平に延びる天部を介して連設されていてもよい（請求項２）。 Here, a wall body standing substantially vertically may be provided on the tight frame, and the first locked portion may be connected to the upper end of the wall body via a top portion extending directly or horizontally ( Claim 2).

さらに、前記タイトフレームは、その両端に前記壁体が設けられ、隣り合うタイトフレームの壁体どうしが当接するように複数並べて配置されると共に、各タイトフレームの二つの壁体間に前記第二嵌合部が設けられていてもよい（請求項３）。 Further, the tight frame is provided with the wall bodies at both ends thereof and arranged side by side so that the wall bodies of adjacent tight frames are in contact with each other, and the second frame is interposed between the two wall bodies of each tight frame. A fitting part may be provided (Claim 3).

請求項１〜３に係る発明では、十分な強度および水密性能を確保するとともに施工性に優れ、梁と梁の中間部においても折板屋根材どうしのすくいかぶせの嵌合が容易となる嵌合式折板屋根材の取付構造が得られる。すなわち、本発明では、タイトフレームに折板屋根材を取り付ける際に、両者の嵌合作業を行えばよく、馳締め等の手間がかかる作業が不要であるから、施工性に優れたものとなる。また、本発明では、折板屋根材とタイトフレームとの嵌合部分として、前記頂部と第一嵌合部、前記底部と第二嵌合部の２種の嵌合部分を設けるので、前記２種の嵌合部分の一方に耐風圧（負圧）強度を持たせ、他方に水密性能を持たせれば、各嵌合部分の構造をシンプルにすることができ、部品点数も最小限に抑えることができる。 In the inventions according to claims 1 to 3 , a fitting type that ensures sufficient strength and water-tightness, is excellent in workability, and facilitates fitting of folded roofing materials between the folded-plate roof materials even in the middle part of the beams. An installation structure for folded plate roofing material is obtained. That is, in the present invention, when the folded roof material is attached to the tight frame, it is only necessary to perform a fitting operation between them, and an operation that requires labor such as tightening is unnecessary, so that the workability is excellent. . Further, in the present invention, as the fitting portion between the folded plate roof material and the tight frame, two types of fitting portions of the top portion and the first fitting portion and the bottom portion and the second fitting portion are provided. If one of the mating parts has windproof (negative pressure) strength and the other has watertightness, the structure of each mating part can be simplified and the number of parts can be minimized. Can do.

特に、前記第二嵌合部に主に耐風圧強度を負担させることにより、第一嵌合部は折板屋根材どうしのすくいかぶせの連結と水密性能を主に負担することが可能になる。このとき、すくいかぶせにより連結される折板屋根材の頂部（連結部）を第一嵌合部と相互に深く嵌合させる必要が無く、折板屋根材の頂部どうしの嵌め込みやすさを重視した形状とすることが可能になる。従って、梁と梁の中間部分のタイトフレームが無い部分でも、折板屋根材どうしのすくいかぶせによる嵌合を容易に行うことができる。 In particular, by making the second fitting part mainly bear wind pressure strength, it is possible for the first fitting part to mainly bear the connection between the folded roof materials and the watertight performance. At this time, there is no need to fit the top part (joint part) of the folded-plate roof material connected by scooping deeply with the first fitting part, and emphasis was placed on the ease of fitting between the top parts of the folded-plate roof material. It becomes possible to make it into a shape. Therefore, it is possible to easily perform the fitting by folding the folded-plate roof materials even in a portion where there is no tight frame in the middle portion between the beams.

また、第一嵌合部の役割が折板相互の連結と水密性能の確保であれば、折板屋根材の中間山部の第一嵌合部はタイトフレームに係止する必要が無い。即ち、折板屋根材の中間山部は第二係止部で強固にタイトフレームに係止されていればよい。従って、請求項１に記載しているように、前記タイトフレームの第一被係止部を、前記折板屋根材のすくいかぶせに相対する部分のみに設け、折板屋根材の中間山部に相対するタイトフレームの部分には第一被係止部（第一嵌合部）を設けず第二被係止部（第二嵌合部）のみとすることが可能となり、この場合、タイトフレームの構造が簡略化され、コストを大幅に下げ、軽量化を図ることが可能である。 Moreover, if the role of a 1st fitting part ensures the connection and watertight performance of folded plates, the 1st fitting part of the intermediate peak part of a folded-plate roof material does not need to latch to a tight frame. In other words, the intermediate peak portion of the folded plate roof material only needs to be firmly locked to the tight frame by the second locking portion. Therefore, as described in claim 1, the first locked portion of the tight frame is provided only in a portion facing the rake of the folded plate roof material, and the intermediate mountain portion of the folded plate roof material is provided. It is possible to provide only the second locked portion (second fitting portion) without providing the first locked portion (first fitting portion) in the opposing tight frame portion. The structure can be simplified, the cost can be greatly reduced, and the weight can be reduced.

ここで、小壁１５を挟んで設けられた壁部１４の向かい合う二つの第二被係止部１６によって、前記折板屋根材１の底部３が嵌合固定される第二嵌合部Ｋ２が構成される。 Here, the second fitting portion K2 to which the bottom portion 3 of the folded plate roofing material 1 is fitted and fixed by the two second locked portions 16 facing each other of the wall portion 14 provided across the small wall 15 is provided. Composed.

上記タイトフレーム９に折板屋根材１を取り付けるには、図４に示すように、隣り合うタイトフレーム９の壁体１１，１２を当接させ、これにより形成された前記第一嵌合部Ｋ１を折板屋根材１の前記頂部４’に嵌合固定する。このとき、壁体１１，１２の第一被係止部１１ａ，１２ａにそれぞれ折板屋根材１の第一係止部７’の上側縮小斜面部２ｂが直接係止した状態となる。同時に、前記頂部４’にすくいかぶせの嵌合によって連結される頂部４の第一係止部７が、この頂部４’の第一係止部７’を介して前記第一被係止部１１ａ，１２ａに間接的に係止した状態となる。 In order to attach the folded roof material 1 to the tight frame 9, as shown in FIG. 4, wall bodies 11 and 12 of the adjacent tight frames 9 are brought into contact with each other, and the first fitting portion K1 formed thereby is used. Is fitted and fixed to the top 4 ′ of the folded roof material 1. At this time, the upper reduced slope portion 2b of the first locking portion 7 'of the folded roof material 1 is directly locked to the first locked portions 11a and 12a of the walls 11 and 12, respectively. At the same time, the first locking portion 7 of the top portion 4 connected to the top portion 4 ′ by fitting the top portion 4 ′ is connected to the first locked portion 11a via the first locking portion 7 ′ of the top portion 4 ′. , 12a is indirectly locked.

また、折板屋根材１の各底部３をタイトフレーム９の第二嵌合部Ｋ２に嵌合固定する。このとき、折板屋根材１の側壁部５，６の下部がタイトフレーム９の拡大傾斜部１４ｂに当接するとともに、折板屋根材１の下側縮小斜面部２ｃがタイトフレーム９の縮小傾斜部１４ｃに当接する状態となる。 Further, each bottom portion 3 of the folded plate roof material 1 is fitted and fixed to the second fitting portion K2 of the tight frame 9. At this time, the lower portions of the side wall portions 5 and 6 of the folded plate roof material 1 abut on the enlarged inclined portion 14b of the tight frame 9, and the lower reduced inclined portion 2c of the folded plate roof material 1 is the reduced inclined portion of the tight frame 9. 14c is brought into contact.

上記の作業により、タイトフレーム９に対する折板屋根材１の取り付けが完了する。すなわち、折板屋根材１の頂部４’および底部３にタイトフレーム９の第一嵌合部Ｋ１および第二嵌合部Ｋ２を嵌合する際、第一係止部７，７、第二係止部８，８、第一被係止部１１ａ，１２ａおよび第二被係止部１６，１６がそれぞれ適宜に弾性変形し、嵌合後には各部のスプリングバック効果によってその嵌合状態が良好に保たれることになる。 With the above operation, the attachment of the folded plate roof material 1 to the tight frame 9 is completed. That is, when the first fitting portion K1 and the second fitting portion K2 of the tight frame 9 are fitted to the top portion 4 ′ and the bottom portion 3 of the folded roof material 1, the first locking portions 7, 7 and the second engagement portion are engaged. The stop portions 8, 8, the first locked portions 11a, 12a, and the second locked portions 16, 16 are appropriately elastically deformed, and after fitting, the fitting state is good due to the springback effect of each portion. Will be kept.

なお、この実施の形態では、前記すくいかぶせの嵌合により隣の折板屋根材１の頂部４が上側に嵌装されたすくい側の頂部４’に、第一嵌合部Ｋ１が嵌合するように構成されており、前記タイトフレーム９の第一被係止部１１ａ，１２ａを、前記すくいかぶせに相対する部分のみに設けてある。また、各タイトフレーム９は、３山タイプの折板屋根材１に対応した形状・サイズとなっており、各折板屋根材１の三つの底部３に嵌合する三つの第二嵌合部Ｋ２を備え、さらに、両端の壁部１４Ａ，１４Ｂは壁部１４をほぼ半分に切断した形状となっている。 In this embodiment, the first fitting portion K1 is fitted to the top portion 4 'on the rake side where the top portion 4 of the adjacent folded plate roofing material 1 is fitted on the upper side by the fitting of the rake. The first locked portions 11a and 12a of the tight frame 9 are provided only in the portion facing the scooping. Each tight frame 9 has a shape and size corresponding to the three-fold type folded-plate roofing material 1, and three second fitting portions that fit into the three bottom portions 3 of each folded-plate roofing material 1. K2 is provided, and the wall portions 14A and 14B at both ends have a shape obtained by cutting the wall portion 14 into almost half.

上記の構成からなる取付構造では、折板屋根材１の頂部４’と第一嵌合部Ｋ１との嵌合部分は、折板屋根材１どうしを連結する役割と水密性能を発揮する役割とを持ち、折板屋根材１の底部３と第二嵌合部Ｋ２との嵌合部分は、耐風圧（負圧）強度を負担する役割を持つことになる。このように役割を上記２種の嵌合部分に分担させたことにより、各嵌合部分を備えた前記取付構造はシンプルな構成で部品点数の少ないものとなっている。 In the mounting structure having the above configuration, the fitting portion between the top 4 ′ of the folded plate roofing material 1 and the first fitting portion K1 has a role of connecting the folded plate roofing materials 1 to each other and a role of exhibiting watertight performance. The fitting part of the bottom part 3 of the folded-plate roof material 1 and the 2nd fitting part K2 has a role which bears wind-proof pressure (negative pressure) intensity | strength. As described above, since the roles are assigned to the two types of fitting portions, the mounting structure including the fitting portions has a simple configuration and a small number of parts.

また、折板屋根材１の底部３に対する第二嵌合部Ｋ２の嵌合により耐風圧強度を確保しているので、タイトフレーム９の両端のみに第一嵌合部Ｋ１を構成する同一形状の壁体１１，１２等を設け、その間に折板屋根材１の底部３に嵌合する第二嵌合部Ｋ２を設けるだけで十分であり、第一嵌合部Ｋ１を例えば各壁部１４の中央に設ける必要はない。しかし、壁部１４の中央に第一嵌合部Ｋ１を設けてもよい。 Further, since the wind pressure strength is secured by fitting the second fitting portion K2 to the bottom portion 3 of the folded roof material 1, the same shape that forms the first fitting portion K1 only at both ends of the tight frame 9 is obtained.
