このうち、右側の屋根板１ａ及び左側の屋根板１ｂは、図２に示すとおり、略平坦な屋根板本体１１と、その左右に位置する左側縁部１２及び右側縁部１３とを有する。右側の屋根板１ａ及び左側の屋根板１ｂはいずれも１枚の金属製板材を曲げ加工により折り曲げて一体に形成されている。図１（Ａ）において、右側の屋根板１ａ及び左側の屋根板１ｂはいずれも図２に示す屋根板１と同一の形状及び構成を有しており、この屋根板１を家屋等の建物の上部に左右に並列して配置したものである。以下では、右側の屋根板１ａ及び左側の屋根板１ｂに共通する部分については屋根板１として説明し、特に左右を明示する必要があるときは右側の屋根板１ａ又は左側の屋根板１ｂであることを明示して説明することとする。 As shown in FIG. 1 (A), this embodiment includes a right roof plate 1a, a left roof plate 1b, and a suspension 2.
Among these, the right roof board 1a and the left roof board 1b have the substantially flat roof board main body 11, and the left side edge part 12 and the right side edge part 13 located in the right and left as shown in FIG. Both the right roof plate 1a and the left roof plate 1b are integrally formed by bending one metal plate material by bending. In FIG. 1A, the right roof board 1a and the left roof board 1b both have the same shape and configuration as the roof board 1 shown in FIG. 2, and this roof board 1 is used for a building such as a house. It is arranged in parallel on the left and right at the top. In the following, a portion common to the right roof plate 1a and the left roof plate 1b will be described as the roof plate 1, and in particular, when it is necessary to clearly indicate the left and right, the right roof plate 1a or the left roof plate 1b. This will be explained clearly.

屋根板本体１１は野地板等の下地部材４の上に配置され、その上面側が屋外側に位置するようになっている。 The roof board main body 11 is disposed on a base member 4 such as a field board, and its upper surface side is positioned on the outdoor side.

屋根板１の左側縁部１２は、曲げ加工により上方に折り曲げられて立ち上がり部１２１（第１の立ち上がり部１２１）を形成している。第１の立ち上がり部１２１の基端部には傾斜部１２２（第１の傾斜部１２２）が形成されている。さらに、第１の立ち上がり部１２１は、この傾斜部１２２の上部に垂直部１２３を有する。この垂直部１２３は、屋根板本体１１に対し直角方向となるように傾斜部１２２の上部に設けられている。この垂直部１２３の上部は屋根板本体１１の上面側に折り返され、斜め下方に向けて下方広がり状に延びている。この折り返し部は被係止部１２４となっており、後述する吊子２の係止部２３内に受け入れられて係止されるようになっている。屋根板本体１１の上面側に折り返された折り返し端は、内側に丸め込まれて端部処理がなされ、これが被係止部１２４の下端１２４ａとなっている。 The left edge portion 12 of the roof plate 1 is bent upward by bending to form a rising portion 121 (first rising portion 121). An inclined portion 122 (first inclined portion 122) is formed at the proximal end portion of the first rising portion 121. Further, the first rising portion 121 has a vertical portion 123 above the inclined portion 122. The vertical portion 123 is provided on the upper portion of the inclined portion 122 so as to be perpendicular to the roof plate main body 11. The upper portion of the vertical portion 123 is folded back to the upper surface side of the roof plate main body 11 and extends downward and obliquely downward. The folded portion is a locked portion 124, which is received and locked in a locking portion 23 of the suspension 2 described later. The folded end that is folded back to the upper surface side of the roof plate body 11 is rolled inward to be subjected to end processing, which is the lower end 124 a of the locked portion 124.

屋根板１の右側縁部１３は、曲げ加工により上方に折り曲げられて立ち上がり部１３１（第２の立ち上がり部１３１）を形成している。第２の立ち上がり部１３１の基端部には傾斜部１３２（第２の傾斜部１３２）が形成されている。さらに、第２の立ち上がり部１３１は、この傾斜部１３２の上部に垂直部１３３を有する。この垂直部１３３は、屋根板本体１１に対し直角方向となるように傾斜部１３２の上部に設けられている。この垂直部１３３の上部は屋根板本体１１とは反対側に折り曲げられている。この折曲部は比較的幅広で、上方に緩やかに湾曲するように折り曲げられており、この幅広の折曲部が嵌合連結用の雌形凸条１３４となる。 The right edge 13 of the roof plate 1 is bent upward by bending to form a rising portion 131 (second rising portion 131). An inclined portion 132 (second inclined portion 132) is formed at the proximal end portion of the second rising portion 131. Further, the second rising portion 131 has a vertical portion 133 above the inclined portion 132. The vertical portion 133 is provided on the upper portion of the inclined portion 132 so as to be perpendicular to the roof plate main body 11. The upper part of the vertical part 133 is bent on the side opposite to the roof plate body 11.

The falling portion 135 and the vertical portion 133 are formed on surfaces substantially parallel to each other. A lower end of the falling portion 135 is bent toward the second rising portion 131 to form a retaining portion 136. The retaining portion 136 is bent so as to be slightly folded back toward the falling portion 135. In other words, the angle θ formed by the retaining portion 136 and the falling portion 135 is less than 90 °, whereby the retaining portion 136 is directed from the lower end of the falling portion 135 toward the second rising portion 131 side. This will incline upward, and this will strengthen the retaining action of the retaining part 136. In the present embodiment, this angle θ is about 85 °. However, the angle θ is not necessarily less than 90 °, and may be 90 ° (right angle) or may be an angle exceeding 90 °.

抜け止め部１３６はさらに第２の立ち上がり部１３１の垂直部１３３との間に僅かに隙間を設けて下方に折り曲げられ、この折曲部分が狭隘部１３７となっている。さらに、この狭隘部１３７よりも下方の部分は、下方広がり状に拡開されてスカート部１３８が形成されている。そして、このスカート部１３８の下端１３８ａは内側に丸め込まれて端部処理がなされ、この部分が後述するように当接部として機能するようになっている。 The retaining portion 136 is further bent downward with a slight gap between it and the vertical portion 133 of the second rising portion 131, and this bent portion is a narrow portion 137. Further, a portion below the narrowed portion 137 is widened downward to form a skirt portion 138. And the lower end 138a of this skirt part 138 is rounded inside, and an edge part process is made | formed, and this part functions as a contact part so that it may mention later.

他方、吊子２は、図５に示すとおり、１枚の金属製板材を曲げ加工により断面Ｓ字状に折り曲げて一体に形成されており、固定部２１と立ち上がり部２２（第３の立ち上がり部２２）と係止部２３とを有する。吊子２は通し吊子であっても部分吊子であってもよい。固定部２１は、図１（Ａ）に示すとおり、ビス等の固定手段５により野地板等の下地部材４に固定される。第３の立ち上がり部２２は固定部２１から直角に折り上げられている。他方、第３の立ち上がり部２２の上部は、固定部２１とは反対側に折り曲げられた上、下方広がり状に折り返されており、この折曲部が係止部２３として機能するようになっている。具体的には、上記折曲部の内側の凹曲部が係止部２３となっており、この凹曲部に右側の屋根板１ａの被係止部１２４が受け入れられて係止されることになる。係止部２３として機能するこの凹曲部は、被係止部１２４が下から挿入されるように開口部が下方に向いており、上方に向けて先細り状になっている。そして、係止部２３の外形についても、上方に向けて先細り状になっており、狭隘部１３７を挿通させて嵌合連結用の雌形凸条１３４内に係止部２３を収容し易くなっている。 On the other hand, as shown in FIG. 5, the hanging element 2 is integrally formed by bending one metal plate material into a S-shaped cross section by bending, and includes a fixed portion 21 and a rising portion 22 (third rising portion). 22) and a locking part 23. The hanger 2 may be a through hanger or a partial hanger. As shown in FIG. 1 (A), the fixing portion 21 is fixed to a base member 4 such as a field plate by fixing means 5 such as screws. The third rising portion 22 is folded at a right angle from the fixed portion 21. On the other hand, the upper portion of the third rising portion 22 is bent to the side opposite to the fixed portion 21 and is folded back so as to expand downward, and this bent portion functions as the locking portion 23. Yes. Specifically, the concave portion on the inner side of the bent portion is a locking portion 23, and the locked portion 124 of the right roof plate 1a is received and locked to the concave portion. become. The concavely curved portion functioning as the locking portion 23 has an opening facing downward so that the locked portion 124 is inserted from below, and is tapered upward. The outer shape of the locking portion 23 is also tapered upward, and the narrow portion 137 is inserted so that the locking portion 23 can be easily accommodated in the female ridge 134 for fitting connection. ing.

The assembly procedure is as follows. First, the hanger 2 is fixed to the base member 4 such as a field board with fixing means 5 such as screws. Next, the locked portion 124 of the right roof plate 1 a is inserted into the locking portion 23 of the hanging element 2 from below. In this state, the female ridge 134 for fitting and connecting the left roof plate 1b is externally fitted to the locking portion 23. As a result, the left and right roof plates 1a and 1b are connected to each other via the suspension 2 and fixed to the upper part of the building.

なお、左側の屋根板１ｂの嵌合連結用の雌形凸条１３４を係止部２３に外嵌するには、係止部２３を狭隘部１３７の隙間から内部に通す必要があるが、係止部２３の外面が先細り状に形成されているため、可撓性を利用して左側の屋根板１ｂの立ち下げり部１３５を弾性変形させて狭隘部１３７の隙間を広げることができるので、嵌合連結用の雌形凸条１３４を容易に係止部２３に外嵌することができる。 In order to externally fit the female projection 134 for fitting and connecting the left roof plate 1b to the locking portion 23, it is necessary to pass the locking portion 23 through the gap of the narrow portion 137. Since the outer surface of the stop portion 23 is formed in a tapered shape, the falling portion 135 of the left roof plate 1b can be elastically deformed using flexibility, and the gap of the narrow portion 137 can be widened. The female ridge 134 for fitting and coupling can be easily fitted on the locking portion 23.

この組み付け状態において、右側の屋根板１ａの第１の立ち上がり部１２１と左側の屋根板１ｂの第２の立ち上がり部１３１とは吊子２の第３の立ち上がり部２２を間に挟んで積層状に重なり合うようになっている。すなわち、右側の屋根板１ａの第１の立ち上がり部１２１は吊子２の第３の立ち上がり部２２に右側から密接し、左側の屋根板１ｂの第２の立ち上がり部１３１はその反対側から吊子２の第３の立ち上がり部２２に密接するようになっている。そして、このようにして３つの部材１ａ・１ｂ・２の板状部分１２１・１３１・２２が積層状に重なり合った状態で、左側の屋根板１ｂの狭隘部１３７と右側の屋根板１ａの第１の立ち上がり部１２１との間に隙間ｓが形成されるようになっている。 In this assembled state, the first rising portion 121 of the right roof plate 1a and the second rising portion 131 of the left roof plate 1b are laminated with the third rising portion 22 of the suspension 2 interposed therebetween. It is supposed to overlap. That is, the first rising portion 121 of the right roof plate 1a is in close contact with the third rising portion 22 of the hanger 2 from the right side, and the second rising portion 131 of the left roof plate 1b is the hanger from the opposite side. The second third rising portion 22 is closely connected. In this way, with the plate-like portions 121, 131, and 22 of the three members 1a, 1b, and 2 overlapped in a stacked manner, the narrow portion 137 of the left roof plate 1b and the first roof plate 1a of the right roof plate 1a. A gap s is formed between the first rising portion 121 and the second rising portion 121.

なお、本実施例においてビスやボルト等の固定手段を使用するのは吊子２を下地部材４に固定する場合だけであり、それ以外の箇所には使用していない。すなわち、屋根板１ａ・１ｂ相互の連結や吊子２と屋根板１ａ又は１ｂとの連結はすべてボルト等を使用しない嵌合式となっている。このため、無暗に屋根板１ａ・１ｂにビスやボルト等を挿通するための穴をあける必要がなく、雨水等の侵入を防止できる。 In the present embodiment, fixing means such as screws and bolts are used only when the hanging element 2 is fixed to the base member 4 and is not used in other places. That is, the mutual connection between the roof plates 1a and 1b and the connection between the hanger 2 and the roof plate 1a or 1b are all fitted without using bolts or the like. For this reason, it is not necessary to make a hole for inserting a screw, a bolt, or the like in the roof plates 1a and 1b without darkness, and entry of rainwater or the like can be prevented.

また、この種の吊子を用いるタイプの屋根板の連結構造では、従来、キャップと呼ばれる部材を必要としたが、本実施例では、屋根板自体に設けられている嵌合連結用の雌形凸条１３４がキャップの機能を果たすため別途キャップを設ける必要がない。このため、吊子を用いるタイプの連結構造でありながら、部品点数を削減できる。 In addition, the roof plate connection structure of this type that uses this type of hanging element has conventionally required a member called a cap, but in this embodiment, the female shape for fitting connection provided on the roof plate itself. Since the ridge 134 functions as a cap, it is not necessary to provide a cap separately. For this reason, although it is a connection structure of a type using a suspension, the number of parts can be reduced.

本実施例は、さらに、組み付け状態において以下のような特徴を有している。
まず、図１（Ａ）に示すとおり、左側の屋根板１ｂのスカート部１３８の下端１３８ａが右側の屋根板１ａの傾斜部１２２（第１の傾斜部１２２）の傾斜面に当接するようになっている。これにより、雨水等はこの傾斜面で跳ね返され、たとえ雨水等がスカート部１３８の下端１３８ａと傾斜部１２２との間から侵入したとしても、雨水等はこの傾斜面を流れ落ちるため、それ以上の侵入は防止される。 The present embodiment further has the following characteristics in the assembled state.
First, as shown in FIG. 1A, the lower end 138a of the skirt portion 138 of the left roof plate 1b comes into contact with the inclined surface of the inclined portion 122 (first inclined portion 122) of the right roof plate 1a. ing. As a result, rainwater or the like is rebounded on the inclined surface, and even if rainwater or the like enters from between the lower end 138a of the skirt portion 138 and the inclined portion 122, the rainwater or the like flows down the inclined surface. Is prevented.

また、本実施例では、図１（Ｂ）に拡大して示すとおり、組み付け状態において、狭隘部１３７には隙間ｓが形成されている。すなわち、右側の屋根板１ａの立ち上がり部１２１（第１の立ち上がり部１２１）と左側の屋根板１ｂの狭隘部１３７との間に通常時は隙間ｓが形成されており、この狭隘部１３７において左右の屋根板１ａ・１ｂがわずかに離間している。
また、右側の屋根板１ａの被係止部１２４の下端１２４ａと左側の屋根板１ｂの抜け止め部１３６との間にも通常時は隙間ｔが形成されるようになっており、両者がわずかに離間している。
なお、左側の屋根板１ｂの立ち下がり部１３５と抜け止め部１３６とのなす角θが９０°未満であることは前述のとおりである。 In the present embodiment, as shown in an enlarged view in FIG. 1B, a gap s is formed in the narrow portion 137 in the assembled state. That is, a gap s is normally formed between the rising portion 121 (first rising portion 121) of the right roof plate 1a and the narrow portion 137 of the left roof plate 1b. The roof plates 1a and 1b are slightly separated from each other.
In addition, a gap t is normally formed between the lower end 124a of the locked portion 124 of the right roof plate 1a and the retaining portion 136 of the left roof plate 1b. Are separated.
As described above, the angle θ formed by the falling portion 135 of the left roof plate 1b and the retaining portion 136 is less than 90 °.

この結果、本実施例は以下のような効果を奏する。すなわち、例えば強風等により屋根板１ａ・１ｂに負圧が作用して屋根板１ａ・１ｂが若干浮き上がったとする。この場合、屋根板１ａ・１ｂは、通常、その真ん中あたり（図２の中心部付近）が持ち上がるように変形する。これを図１（Ａ）の右側の屋根板１ａについてみると、右側の屋根板１ａは第１の傾斜部１２２を介して左側の屋根板１ｂの当接部すなわちスカート部１３８の下端１３８ａを押し上げることになる。このスカート部１３８の下端１３８ａの押し上げはさらに左側の屋根板１ｂの抜け止め部１３６を上方に押し上げることになるが、この押し上げは抜け止め部１３６の抜け止め作用をより強固にする方向に働くため、結果的に右側の屋根板１ａはより強固に保持されることになる。このため、右側の屋根板１ａが外れて飛ばされるおそれがない。 As a result, the present embodiment has the following effects. That is, for example, it is assumed that the roof plates 1a and 1b are slightly lifted by a negative pressure acting on the roof plates 1a and 1b due to strong winds or the like. In this case, the roof plates 1a and 1b are usually deformed so that the middle portion thereof (near the center of FIG. 2) is lifted. Looking at this on the right roof plate 1a in FIG. 1A, the right roof plate 1a pushes up the contact portion of the left roof plate 1b through the first inclined portion 122, that is, the lower end 138a of the skirt portion 138. It will be. The push-up of the lower end 138a of the skirt portion 138 pushes the retaining portion 136 of the left roof plate 1b upward, but this push-up works in a direction that strengthens the retaining action of the retaining portion 136. As a result, the right roof plate 1a is more firmly held. For this reason, there is no possibility that the right roof plate 1a may come off and be blown away.

同様に左側の屋根板１ｂについてみても、強風等の負圧により左側の屋根板１ｂの真ん中あたりが浮き上がるように変形した場合、第２の立ち上がり部１３１はその基端部を中心に外方に広がろうとするが、これは結果的に抜け止め部１３６を食い込ませるように作用するため、左側の屋根板１ｂもしっかりと保持されることになる。 Similarly, when the left roof plate 1b is also deformed so that the center of the left roof plate 1b is lifted by negative pressure such as a strong wind, the second rising portion 131 is centered on the base end portion outward. Although it tries to spread, this acts to cause the retaining portion 136 to bite in as a result, so that the left roof plate 1b is also firmly held.

さらに、本実施例では、図１（Ａ）に示すとおり、第１の傾斜部１２２と第２の傾斜部１３２とは同一の傾斜角φを有するようになっており、かつ、第２の傾斜部１３２の上端の位置Ｘが、第１の傾斜部１２２と立ち下がり部１３５の延長線の交わる位置Ｙと同じ高さにあるようになっている。この結果、本実施例は、外観上、嵌合連結用の雌形凸条１３４の中心線Ｗを挟んで左右対称に見えることになり、美観が向上する。また、本実施例では、上記第１の傾斜部１２２と第２の傾斜部１３２の傾斜角φは３９°となっている。この傾斜角φは、３０°〜６０°の範囲の角度であることが風雨に対する各屋根板１ａ・１ｂの固定機能を十分に発揮する上で好ましい。 Furthermore, in this embodiment, as shown in FIG. 1A, the first inclined portion 122 and the second inclined portion 132 have the same inclination angle φ, and the second inclined portion. The position X of the upper end of the portion 132 is at the same height as the position Y where the extension line of the first inclined portion 122 and the falling portion 135 intersects. As a result, the present embodiment looks symmetric with respect to the center line W of the female ridge 134 for fitting and coupling, and the appearance is improved. In the present embodiment, the inclination angle φ of the first inclined portion 122 and the second inclined portion 132 is 39 °. The inclination angle φ is preferably an angle in the range of 30 ° to 60 ° in order to sufficiently exhibit the function of fixing the roof plates 1a and 1b against wind and rain.

図６〜８は、本発明の別実施例を示している。なお、先の実施例と同じ部材及び対応する部分には同じ符号を付している。 6-8 show another embodiment of the present invention. In addition, the same code | symbol is attached | subjected to the same member as the previous Example, and a corresponding part.

まず、この別実施例では、図７に端的に示されるように、屋根板１（図６における左側の屋根板１ｂ）の右側縁部１３の立ち下がり部１３５の下がり具合の態様において、先の実施例と異なる。すなわち、先の実施例では、立ち下がり部１３５が垂直部１３３と略平行になるように形成されていたが（図１・４参照）、この別実施例では、立ち下がり部１３５が下方に向けて末広がり状に広がるように予め形成されている。この結果、嵌合連結用の雌形凸条１３４を吊子２の上部（つまり係止部２３）に外嵌する際に、立ち下がり部１３５を弾性変形しやすくなり、両者を嵌合させる作業が容易になる。 First, in this alternative embodiment, as briefly shown in FIG. 7, in the manner in which the falling portion 135 of the right edge 13 of the roof plate 1 (the left roof plate 1 b in FIG. 6) is lowered, Different from the embodiment. That is, in the previous embodiment, the falling portion 135 was formed so as to be substantially parallel to the vertical portion 133 (see FIGS. 1 and 4), but in this alternative embodiment, the falling portion 135 is directed downward. It is formed in advance so as to spread in a divergent shape. As a result, when the female ridge 134 for fitting and connecting is externally fitted to the upper portion (that is, the locking portion 23) of the hanging piece 2, the falling portion 135 is easily elastically deformed, and the two are fitted together. Becomes easier.

次に、この別実施例では、抜け止め部１３６と立ち下がり部１３５とのなす角度θが９０°よりも大きくなっている点で、先の実施例と相違している。これにより、抜け止め部１３６は立ち下がり部１３５の下端から斜め下方、つまり、第２の立ち上がり部１３１側に向けて下方に傾斜することになる。この点でも、この別実施例では、嵌合連結用の雌形凸条１３４を吊子２の上部（つまり係止部２３）に外嵌しやすくなっている。 Next, this another embodiment is different from the previous embodiment in that the angle θ formed by the retaining portion 136 and the falling portion 135 is larger than 90 °. Thereby, the retaining portion 136 is inclined obliquely downward from the lower end of the falling portion 135, that is, downward toward the second rising portion 131 side. In this respect as well, in this alternative embodiment, the female ridge 134 for fitting and coupling is easily fitted on the upper portion (that is, the locking portion 23) of the suspension 2.

なお、この別実施例においても、スカート部１３８の下端１３８ａが右側の屋根板１ａの傾斜部１２２（第１の傾斜部１２２）の傾斜面に当接するようになっている点は先の実施例と同様である。 In this alternative embodiment, the lower end 138a of the skirt 138 is in contact with the inclined surface of the inclined portion 122 (first inclined portion 122) of the right roof plate 1a. It is the same.

さらに、この別実施例では、吊子２が押出成形により製造されたアルミニウム合金製の押出型材からなっている点で、先の実施例と相違している。これにより、吊子２の厚みを厚くして強度を高めることができる。なお、図６では明示されていないが、この別実施例においても、吊子２がビス等の固定手段によって下地部材４に固定されている点は、先の実施例の場合と同様である。また、吊子２が通し吊子であっても部分吊子であってもよい点も、先の実施例の場合と同様である。 Furthermore, this another embodiment is different from the previous embodiment in that the hanging piece 2 is made of an aluminum alloy extruded mold produced by extrusion. Thereby, the thickness of the hanging element 2 can be increased to increase the strength. Although not clearly shown in FIG. 6, in this another embodiment, the point that the suspension 2 is fixed to the base member 4 by fixing means such as a screw is the same as in the previous embodiment. Further, the point that the hanging element 2 may be a through hanging element or a partial hanging element is the same as in the previous embodiment.

この別実施例においても、先の実施例と同様、ビスやボルト等の固定手段を使用するのは吊子２を下地部材４に固定する場合だけであり、それ以外の箇所には使用していない。つまり、この別実施例においても、屋根板１ａ・１ｂ相互の連結や吊子２と屋根板１ａ又は１ｂとの連結はすべてボルト等を使用しない嵌合式となっている。このため、無暗に屋根板１ａ・１ｂにビスやボルト等を挿通するための穴をあける必要がなく、雨水等の侵入を効果的に防止することができる。 In this alternative embodiment, as in the previous embodiment, the fixing means such as screws and bolts are used only when fixing the suspension 2 to the base member 4 and are used in other places. Absent. That is, also in this other embodiment, the connection between the roof plates 1a and 1b and the connection between the hanger 2 and the roof plate 1a or 1b are all fitting types that do not use bolts or the like. For this reason, it is not necessary to make a hole for inserting a screw, a bolt, or the like in the roof plates 1a and 1b without darkness, and intrusion of rainwater or the like can be effectively prevented.

また、この別実施例においても、先の実施例と同様、屋根板自体に設けられている嵌合連結用の雌形凸条１３４がキャップの機能を果たすため、別途キャップを設ける必要がない。この結果、吊子を用いるタイプの屋根板の連結構造でありながら、部品点数を削減することができる。 Also in this alternative embodiment, as in the previous embodiment, the female connecting ridge 134 for fitting and coupling provided on the roof plate itself fulfills the function of a cap, so there is no need to provide a separate cap. As a result, it is possible to reduce the number of parts while having a connecting structure of roof plates of a type using a hanging element.
