Description

本発明は、折板屋根を形成する際に、折板屋根材をタイトフレームに取り付けるために用いられる吊子に関するものである。 The present invention relates to a hanging member used for attaching a folded plate roof material to a tight frame when forming the folded plate roof.

従来より、屋根下地の上にタイトフレームを取り付け、このタイトフレームに折板屋根材を保持させることによって、複数の折板屋根材からなる折板屋根を形成することが行われている（例えば、特許文献１参照）。この場合、折板屋根材４９は吊子２によりタイトフレームに連結されるものである。吊子２は鋼板等の金属板を折り曲げ加工して形成されるものであり、吊子２の下部をタイトフレームに連結し、吊子２の上部に設けた係止部１９を折板屋根材４９の被嵌合部５４に係止するようにして折板屋根材４９を取り付けるものである。また、図１３（ａ）に示すように、折板屋根材４９の被嵌合部５４には他の折板屋根材４９の嵌合部５３を嵌合し、嵌合部５３と被嵌合部５４とを馳締めにより連結するようにしている。 Conventionally, by attaching a tight frame on a roof base and holding the folded plate roof material on the tight frame, forming a folded plate roof made of a plurality of folded plate roof materials has been performed (for example, Patent Document 1). In this case, the folded plate roof material 49 is connected to the tight frame by the hanger 2. The hanging element 2 is formed by bending a metal plate such as a steel plate, the lower part of the hanging element 2 is connected to a tight frame, and the locking portion 19 provided on the upper part of the hanging element 2 is a folded plate roofing material. The folded-plate roof material 49 is attached so as to be engaged with the 49 fitted portions 54. Moreover, as shown to Fig.13 (a), the fitting part 53 of the other folded-plate roof material 49 is fitted to the to-be-fitted part 54 of the folded-plate roof material 49, and the to-be-fitted part 53 and a to-be-fitted The part 54 is connected by tightening.

しかし、吊子２の強度が低いと、折板屋根材４９にかかる負圧荷重などの負荷によって吊子２が変形し、図１３（ｂ）に示すように、嵌合部５３と被嵌合部５４との連結が外れるおそれがあった。 However, when the strength of the hanging element 2 is low, the hanging element 2 is deformed by a load such as a negative pressure load applied to the folded plate roofing material 49, and as shown in FIG. There was a possibility that the connection with the portion 54 was disconnected.

そこで、このような吊子においては、負圧荷重等の負荷に対する強度を大きくするために、金属板の厚みを大きくすることが考えられるが、隣接する折板屋根材が馳締めにより連結される場合、馳締め部分に厚い吊子の係止部が存在することになり、馳締めが完全に行えずに屋根の防水性と強度が低下するおそれがあった。また、吊子２を折り曲げ加工により所定の形状に成形しにくくなるという問題があった。尚、図１３には吊子２の上部を示し、吊子２としてはいわゆるスライド吊子やスライドしない一般的な吊子（固定吊子）のいずれも上記の問題を有している。
特許第３２８８９９１号公報 In order to increase the strength against a load such as a negative pressure load in such a suspension, it is conceivable to increase the thickness of the metal plate, but the adjacent folded plate roofing materials are connected by tightening. In this case, there is a thick hanging portion engaging portion at the tightening portion, and the waterproofing and strength of the roof may be lowered because the tightening cannot be performed completely. Further, there is a problem that it is difficult to form the suspension 2 into a predetermined shape by bending. Note that FIG. 13 shows the upper part of the hanging element 2. As the hanging element 2, both a so-called slide hanging element and a general hanging element that does not slide (fixed hanging element) have the above-mentioned problems.
Japanese Patent No. 32888991

図３（ａ）（ｂ）に示すように、サドル１は一対のサドル半体１０、１０をボルトなどの結合具１１で結合して形成されるものである。サドル半体１０はステンレス鋼板やめっき鋼板や塗装鋼板などの金属板を折り曲げ加工して形成されるものであり、矩形板状の支持片１２の上端に断面略半円弧状の保持部１３を設けると共に支持板１２の下端に載置片１４を設けて形成されている。支持板１２にはネジ孔４４が形成されている。保持部１３と載置片１４とは共に支持板１２の一方の表面よりも外側に突出している。また、一対のサドル半体１０、１０のうちの一方には馳締め係合部１５が設けられている。馳締め係合部１５は支持片１２の下部に断面略つ字状に折り曲げ形成されており、保持部１３や載置片１４と同じ方向で支持板１２の表面に突出して形成されている。 As shown in FIGS. 3A and 3B, the saddle 1 is formed by connecting a pair of saddle halves 10 and 10 with a connecting tool 11 such as a bolt. The saddle half 10 is formed by bending a metal plate such as a stainless steel plate, a plated steel plate, or a coated steel plate, and a holding portion 13 having a substantially semicircular cross section is provided at the upper end of a rectangular plate-like support piece 12. A mounting piece 14 is provided at the lower end of the support plate 12. A screw hole 44 is formed in the support plate 12. Both the holding portion 13 and the mounting piece 14 protrude outward from one surface of the support plate 12. Further, one of the pair of saddle halves 10 and 10 is provided with a tightening engagement portion 15. The clamping engagement portion 15 is formed to be bent in a substantially square cross section at the lower portion of the support piece 12 and is formed to protrude from the surface of the support plate 12 in the same direction as the holding portion 13 and the mounting piece 14.

断熱部材３はサドル１や吊子２よりも熱が伝わりにくい非伝熱性を有するものであり、例えば、ＡＢＳ樹脂などのプラスチックの成形品で形成することができる。この断熱部材３は外形が略小判状の被保持部２２と、被保持部２２の上面にその長手方向の全長にわたって突設された一対のガイド片２３、２３とを備えて形成されている。また、被保持部２２にはその長手方向の両端面と上面とに開口するガイド溝２４が形成されている。被保持部２２の上面におけるガイド溝２４の開口は一対のガイド片２３、２３の間でガイド片２３の長手方向に沿って形成されている。 The heat insulating member 3 has a non-heat transfer property in which heat is less likely to be transmitted than the saddle 1 and the suspension 2, and can be formed of a molded product of plastic such as ABS resin, for example. The heat insulating member 3 includes a held portion 22 whose outer shape is substantially oval, and a pair of guide pieces 23 and 23 projecting from the upper surface of the held portion 22 over the entire length in the longitudinal direction. In addition, the held portion 22 is formed with guide grooves 24 that open to both end surfaces and the upper surface in the longitudinal direction. The opening of the guide groove 24 on the upper surface of the held portion 22 is formed between the pair of guide pieces 23 and 23 along the longitudinal direction of the guide piece 23.

そして、断熱屋根用連結具Ａは次のようにして形成することができる。サドル１は対向配置した一対のサドル半体１０、１０を結合具１１で結合して形成するものである。このとき、一対のサドル半体１０、１０は支持板１２、１２の内面（保持部１３や載置片１４が突出する面と反対側の面）同士を合わせるようにし、ネジ孔４４に結合具１１を螺着することにより結合することができる。また、上記のように結合したサドル半体１０、１０の間には断熱部材３を挟持して保持する。このとき、サドル半体１０の保持部１３の内側に断熱部材３の被保持部２２を嵌め込むようにし、対向するサドル半体１０、１０の保持部１３、１３の間に被保持部２２を介在させるようにする。従って、対向する保持部１３、１３の上端間には断熱部材３のガイド片２３、２３が介在するものである。 And the connector A for heat insulation roofs can be formed as follows. The saddle 1 is formed by connecting a pair of saddle halves 10 and 10 facing each other with a coupler 11. At this time, the pair of saddle halves 10 and 10 are arranged so that the inner surfaces of the support plates 12 and 12 (the surfaces opposite to the surfaces from which the holding portions 13 and the mounting pieces 14 protrude) are aligned with each other. 11 can be connected by screwing. Further, the heat insulating member 3 is sandwiched and held between the saddle halves 10 and 10 coupled as described above. At this time, the held portion 22 of the heat insulating member 3 is fitted inside the holding portion 13 of the saddle half 10, and the held portion 22 is interposed between the holding portions 13 and 13 of the opposing saddle halves 10 and 10. Intervene. Therefore, the guide pieces 23 and 23 of the heat insulating member 3 are interposed between the upper ends of the opposing holding portions 13 and 13.

上記のようにしてサドル１と断熱部材３とを一体化した後、この断熱部材３に吊子２を取り付ける。このとき、図４に示すように、吊子２の底部７６及び装着部１７の部分をガイド溝２４に差し込むと共に吊子２の挟着部１６の部分を断熱部材３のガイド片２３、２３の間に位置させるようにするものであり、これにより、吊子２をスライド吊子としてサドル１及び断熱部材３に対して長手方向にスライド移動自在に取り付けることができる。また、ガイド溝２４に底部７６及び装着部１７を差し込んだ状態で脱落防止片２１を下方に向かって折り曲げる。これにより、脱落防止片２１がガイド溝２４の開口縁部に引っ掛かるようになって、底部７６及び装着部１７の部分をガイド溝２４から抜けないようにすることができ、サドル１及び断熱部材３からの吊子２の脱落を防止することができる。 After the saddle 1 and the heat insulating member 3 are integrated as described above, the hanger 2 is attached to the heat insulating member 3. At this time, as shown in FIG. 4, the bottom portion 76 and the mounting portion 17 of the suspension 2 are inserted into the guide groove 24, and the sandwiching portion 16 portion of the suspension 2 is inserted into the guide pieces 23 and 23 of the heat insulating member 3. Thus, the suspension 2 can be attached to the saddle 1 and the heat insulating member 3 as a slide suspension so as to be slidable in the longitudinal direction. Further, the drop-off prevention piece 21 is bent downward while the bottom 76 and the mounting portion 17 are inserted into the guide groove 24. As a result, the drop-off prevention piece 21 is caught on the opening edge of the guide groove 24, so that the bottom 76 and the mounting portion 17 can be prevented from coming out of the guide groove 24, and the saddle 1 and the heat insulating member 3. It is possible to prevent the suspension 2 from falling off.

Each lower roof material 31 is arranged so as to be positioned. Further, the lower roof materials 31 and 31 adjacent to each other across the convex portion 65 of the tight frame 41 are connected by tightening after fitting the fitting portion 53 and the fitted portion 54 as described above. The mountain portions 51 and 51 are connected and connected to each other, but when tightening, the fixed hanger 48 provided on the convex portion 65 of the tight frame 41 is connected between the fitting portion 53 and the fitted portion 54. Tighten with pinching. In this way, a plurality of folded-plate roofing materials 49 (lower roofing material 31) are connected to the roof base 40 and fixed via the fixed hanger 48 and the tight frame 41. A side folded plate roof can be formed.

上記のようにして下側の折板屋根を形成した後、下側の折板屋根の山部５５の頂部に断熱屋根用連結具Ａのサドル１を取り付ける。このとき、サドル１には断熱部材３が取り付けられているが、吊子２は取り付けられていない。また、サドル１は下側の折板屋根の山部５５の頂部に形成された馳締め部（嵌合部５３と被嵌合部５４の馳締め部分）４７をサドル半体１０、１０で挟持して取り付けることができる。すなわち、頂部片５２の上にサドル半体１０の載置片１４を載せながら、馳締め部４７の両側にサドル半体１０、１０を配置すると共に一方のサドル半体１０に設けた馳締め係合部１５に馳締め部４７を差し込んで係合し、馳締め部４７の上側においてサドル半体１０、１０の支持片１２、１２を貫通するように結合具１１を螺合して締め付けることにより、馳締め部４７をサドル半体１０、１０で挟持し、山部５５の頂部にサドル１を取り付けることができる。また、サドル半体１０、１０の支持片１２、１２の下部と、結合した嵌合部５３及び被嵌合部５４とをビスやボルトなどの固定具４６で連結してサドル１を固定することができる。 After the lower folded plate roof is formed as described above, the saddle 1 of the heat insulating roof connector A is attached to the top of the mountain portion 55 of the lower folded plate roof. At this time, the heat insulating member 3 is attached to the saddle 1, but the hanging piece 2 is not attached. In addition, the saddle 1 is sandwiched between saddle halves 10 and 10 with a tightening portion 47 (a tightened portion between the fitting portion 53 and the fitted portion 54) formed at the top of the mountain portion 55 of the lower folded plate roof. Can be attached. That is, the saddle fastening members provided on one saddle half 10 and the saddle half 10 are arranged on both sides of the fastening portion 47 while the placing piece 14 of the saddle half 10 is placed on the top piece 52. By inserting and engaging the tightening portion 47 into the joint portion 15, the coupling tool 11 is screwed and tightened so as to penetrate the support pieces 12 and 12 of the saddle halves 10 and 10 on the upper side of the tightening portion 47. The saddle tightening portion 47 is sandwiched between the saddle halves 10 and 10, and the saddle 1 can be attached to the top of the mountain portion 55. Also, the saddle 1 is fixed by connecting the lower portions of the support pieces 12 and 12 of the saddle halves 10 and 10 to the connected fitting portion 53 and fitted portion 54 with a fixture 46 such as a screw or bolt. Can do.

上記のようにして下側の折板屋根に複数のサドル１、１…を取り付けた後、下側の折板屋根の上に断熱材５６を配設する。断熱材５６としてはロックウールやグラスウールなどの無機繊維体あるいはウレタンフォームやフェノールフォームなどの樹脂フォームを用いることができる。断熱材５６は下側の折板屋根の上面全面にわたって敷き詰められる。また、下側の折板屋根に取り付けたサドル１はその保持部１３よりも下側の部分が断熱材５６で覆われた状態となり、保持部１３及び断熱部材３は敷き詰めた断熱材５６よりも上側に位置している。 After the plurality of saddles 1, 1,... Are attached to the lower folded plate roof as described above, the heat insulating material 56 is disposed on the lower folded plate roof. As the heat insulating material 56, an inorganic fiber body such as rock wool or glass wool or a resin foam such as urethane foam or phenol foam can be used. The heat insulating material 56 is spread over the entire upper surface of the lower folded plate roof. Further, the saddle 1 attached to the lower folded plate roof is in a state in which the lower part of the saddle 1 is covered with the heat insulating material 56, and the holding portion 13 and the heat insulating member 3 are more than the spread heat insulating material 56. Located on the upper side.

次に、一枚の折板屋根材４９を上側屋根材３０として断熱材５６の上に載置する。このとき、上側屋根材３０は下側屋根材３１と同様に屋根の傾斜方向（流れ方向）を長尺方向として配置する。また、上側屋根材３０の被嵌合部５４は下側の折板屋根に取り付けた上記サドル１の側方に位置し、被嵌合部５４の長手方向とガイド溝２４の長手方向とガイド片２３の長手方向とがほぼ平行な状態となる。 Next, the folded roof material 49 is placed on the heat insulating material 56 as the upper roof material 30. At this time, like the lower roof material 31, the upper roof material 30 is arranged with the roof inclination direction (flow direction) as the long direction. Further, the fitted portion 54 of the upper roof material 30 is located on the side of the saddle 1 attached to the lower folded plate roof, and the longitudinal direction of the fitted portion 54, the longitudinal direction of the guide groove 24, and the guide piece. 23 is substantially parallel to the longitudinal direction.

次に、断熱材５６に載置した上側屋根材３０の被嵌合部５４の下側に吊子２の係止部１９を係止すると共にこの吊子２を上側屋根材３０に近接して位置するサドル１の断熱部材３に差し込むことによって、サドル１と吊子２からなる断熱屋根用連結具Ａに上側屋根材３０を係止する。ここで、吊子２の長手方向の一方に形成した脱落防止片２１は下側に向かって折り曲げられている。従って、吊子２は折り曲げていない脱落防止片２１の方から断熱部材３のガイド溝２４とガイド片２３、２３の間に差し込まれ、吊子２を断熱部材３に差し込んだ後、折り曲げていない方の脱落防止片２１を下方に向かって折り曲げるようにする。尚、図６においては、断熱材５６を図示省略している。 Next, the engaging portion 19 of the hanging element 2 is engaged with the lower side of the fitted portion 54 of the upper roof material 30 placed on the heat insulating material 56 and the hanging element 2 is brought close to the upper roof material 30. By inserting into the heat insulating member 3 of the saddle 1 positioned, the upper roof material 30 is locked to the heat insulating roof connector A composed of the saddle 1 and the suspension 2. Here, the drop-off prevention piece 21 formed on one side in the longitudinal direction of the hanging element 2 is bent downward. Accordingly, the hanging element 2 is inserted between the guide groove 24 of the heat insulating member 3 and the guide pieces 23 and 23 from the unfallen falling prevention piece 21 and is not bent after the hanging element 2 is inserted into the heat insulating member 3. The one falling prevention piece 21 is bent downward. In FIG. 6, the heat insulating material 56 is not shown.

次に、上記とは別の他の上側屋根材３０をさらに断熱材５６の上に載置し、上記吊子２に係止した上側屋根材３０と隣接させる。そして、上記吊子２に係止した上側屋根材３０の被嵌合部５４及び吊子２の突出部１８及び係止部１９を、新たに載置した上側屋根材３０の嵌合部５３の内側に収納して嵌合し、この後に嵌合部５３と被嵌合部５４とを馳締めすることにより、隣接する上側屋根材３０、３０の連結山部５１、５１同士を連結して接続する。このとき、吊子２の係止部１９も馳締めにより折り曲げることができる。 Next, another upper roof material 30 different from the above is further placed on the heat insulating material 56, and is adjacent to the upper roof material 30 locked to the hanging element 2. And the to-be-fitted part 54 of the upper roof material 30 latched by the said hanging element 2, and the protrusion part 18 and the latching part 19 of the hanging element 2 of the fitting part 53 of the upper roof material 30 which newly mounted. It is housed inside and fitted, and then the fitting portion 53 and the fitted portion 54 are tightened to connect and connect the connecting mountain portions 51 and 51 of the adjacent upper roof materials 30 and 30 to each other. To do. At this time, the locking portion 19 of the hanging element 2 can also be bent by tightening.

このようにしてサドル１に対する吊子２の取り付けと、断熱材５６への上側屋根材３０の敷設とを交互に行うことによって、複数枚の上側屋根材３０、３０…が接続された上側の折板屋根を形成することができる。そして、図７に示すように、上側の折板屋根と下側の折板屋根の間は断熱材５６が充填された断熱空間３２として形成され、断熱性の高い二重折板屋根を形成することができる。また、上側の折板屋根は断熱屋根用連結具Ａで下側の折板屋根に連結されて支持されるものである。 In this way, by alternately attaching the suspension 2 to the saddle 1 and laying the upper roof material 30 on the heat insulating material 56, the upper folding member to which the plurality of upper roof materials 30, 30. A plate roof can be formed. And as shown in FIG. 7, it forms as the heat insulation space 32 with which the heat insulating material 56 was filled between the upper folded-plate roof and the lower folded-plate roof, and forms the double folded-plate roof with high heat insulation. be able to. In addition, the upper folded plate roof is connected to and supported by the lower folded plate roof by the heat insulating roof connector A.

本発明の吊子２は、図８（ａ）（ｂ）に示すように、従来の吊子に相当する吊子本体７０を補強部材７１で補強するので、負圧荷重などの負荷に対する強度を大きくして変形を防止することができ、折板屋根材４９の取り付け強度を高めることができる。また、吊子本体７０と補強部材７１とを別々に形成するので、吊子本体７０を形成するのに厚い金属板を用いる場合に比べて、折り曲げ加工が行いやすく、成形しやすいものである。また、かしめ或いは溶接により補強部材７１と吊子本体７０の立ち上がり部７２とを接合して一体化するので、補強部材７１と吊子本体７０の立ち上がり部７２との密着性を上げて断面二次モーメントを大きくすることができ、負圧荷重などの負荷に対する変形をより効果的に防止することができるものである。しかも、補強部材７１は吊子本体７０の立ち上がり部７２の表面にのみ沿わせて密着し、係止部１９には補強部材７１を接触させないようにしているので、隣接する折板屋根材４９、４９を馳締めにより接続する場合にも、隣接する折板屋根材４９、４９の嵌合部５３と被嵌合部５４との間に係止部１９を介在させた状態で容易に折り曲げて馳締めすることができ、係止部１９を馳締め部分に介在させても馳締めを充分強固に行うことができるものである。 As shown in FIGS. 8 (a) and 8 (b), the suspension 2 of the present invention reinforces a suspension body 70 corresponding to a conventional suspension with a reinforcing member 71, so that the strength against a load such as a negative pressure load is increased. The deformation can be prevented by increasing the size, and the attachment strength of the folded roof material 49 can be increased. Moreover, since the hanging body 70 and the reinforcing member 71 are formed separately, compared to the case where a thick metal plate is used to form the hanging body 70, the bending process is easy to perform and the forming is easy. In addition, since the reinforcing member 71 and the rising portion 72 of the hanging body 70 are joined and integrated by caulking or welding, the adhesion between the reinforcing member 71 and the rising portion 72 of the hanging body 70 is increased to obtain a secondary cross section. The moment can be increased, and deformation against a load such as a negative pressure load can be more effectively prevented. In addition, the reinforcing member 71 is in close contact with only the surface of the rising portion 72 of the hanging body 70, and the reinforcing member 71 is not brought into contact with the locking portion 19. Even when 49 is connected by tightening, it can be easily bent with the locking portion 19 interposed between the fitting portion 53 and the fitted portion 54 of the adjacent folded plate roofing materials 49, 49. Even if the latching portion 19 is interposed in the tightening portion, the tightening can be performed sufficiently firmly.

上記では、スライド移動するスライド吊子として使用される吊子２について説明したが、本発明の吊子２はタイトフレーム４１に固定されて移動しない吊子（例えば、上記の固定吊子４８）として形成することもできる。図１０（ｂ）、図１１（ｂ）に示す吊子２は、タイトフレーム４１に固定して使用されるものであって、吊子本体７０と補強部材７１とを備えて形成されている。吊子本体７０は上記と同様の金属板を折り曲げ加工して形成されるものであって、平面視で略台形に形成される固定部８０と、固定部８０の長辺端部から上方に向かって突出する連結部７７と、連結部７７の上端部から側方に向かって突出する突出部１８と、突出部１８の先端部から連結部７７側に向かって斜め下方に突出する係止部１９とを設けて形成されている。固定部８０には上下に貫通する固定孔８３が形成されている。この固定部８０と連結部７７と突出部１８により、吊子２を屋根材保持具６９と連結するための立ち上がり部７２を形成することができる。この実施の形態ではタイトフレーム４１を屋根材保持具６９として用いている。 In the above description, the suspension 2 used as a slide suspension for sliding movement has been described. However, the suspension 2 of the present invention is fixed to the tight frame 41 and does not move (for example, the fixed suspension 48 described above). It can also be formed. 10 (b) and 11 (b) is used by being fixed to the tight frame 41, and is provided with a hanging body 70 and a reinforcing member 71.

本発明の吊子２を用いて、馳締め部４７の開き強度を測定すると、補強部材７１の無い吊子本体７０のみの場合（従来の吊子に相当）に比べて、約１．５倍の強度を発揮することができる。 When the opening strength of the tightening portion 47 is measured using the hanger 2 of the present invention, it is about 1.5 times as compared with the case of only the hanger body 70 without the reinforcing member 71 (corresponding to a conventional hanger). The strength of can be demonstrated.

本発明の吊子２は、折板屋根材４９との馳締め部分の強度が向上するにもかかわらず、馳締め時の施工性は従来と同等となる点に特徴を有するものである。すなわち、隣接する折板屋根材４９、４９と吊子２との馳締め部分において、補強部材７１を用いないと、吊子本体７０の突出部１８が負圧等により持ち上がるように、連結部７７と突出部１８の境界部分が変形し、馳締め部分の強度が低下するおそれがあるが、本発明では、補強部材７１を追加してスポット溶接やかしめなどで一体化することで、連結部７７と突出部１８の板厚を向上したのと同じ効果を得ることができる。また、馳締めは、折板屋根材４９、４９の被嵌合部５４と嵌合部５３と吊子２の係止部１９とを一度に曲げ込むため、単純に吊子２の全体の板厚を上げると、充分な曲げ込み加工（馳折り加工）ができず、馳締め接合部分の強度が低下するおそれがあるが、本発明では、補強部材７１により係止部１９を直接補強しないので、係止部１９も充分な曲げ込み加工を行うことができ、補強部材７１を用いない従来の場合と同様の施工性を有するものである。 The hanging element 2 according to the present invention is characterized in that the workability at the time of tightening is equivalent to that of the related art even though the strength of the tightening portion with the folded-plate roof material 49 is improved. That is, the connecting portion 77 is formed so that the protruding portion 18 of the hanging body 70 is lifted by negative pressure or the like if the reinforcing member 71 is not used in the tightened portion between the adjacent folded plate roof materials 49 and 49 and the hanging piece 2. However, in the present invention, by adding the reinforcing member 71 and integrating them by spot welding or caulking, the connecting portion 77 may be deformed. And the same effect as improving the plate | board thickness of the protrusion part 18 can be acquired. In addition, the tightening is performed by bending the fitted portion 54, the fitting portion 53 of the folded plate roofing materials 49, 49, and the locking portion 19 of the hanging piece 2 at a time, so that the entire plate of the hanging piece 2 is simply made. If the thickness is increased, sufficient bending processing (crease folding) cannot be performed and the strength of the crimped joint portion may be reduced. However, in the present invention, the locking member 19 is not directly reinforced by the reinforcing member 71. The locking portion 19 can also be sufficiently bent and has the same workability as in the conventional case where the reinforcing member 71 is not used.
