次に、中央屋根材３ｂについて説明する。図２に示すように、中央屋根材３ｂは、矩形板状の本体部３１と、この本体部３１の対向する外縁部の一方側に連続する上ハゼ部３２と、本体部３１の対向する外縁部の他方側に連続する下ハゼ部３３と、を備える。図２では、中央屋根材３ｂの下ハゼ部３３が図示されていないが、その構成は、上述の端部屋根材３ａの下ハゼ部３３と同様である。 Next, the central roof material 3b will be described. As shown in FIG. 2, the central roof member 3b includes a rectangular plate-like main body portion 31, an upper seam portion 32 continuing to one side of the opposing outer edge portions of the main body portion 31, and the opposing outer edge portions of the main body portion 31. and a lower seam portion 33 continuous to the other side of the portion. Although FIG. 2 does not show the lower seam portion 33 of the central roof member 3b, its configuration is the same as the lower seam portion 33 of the end roof member 3a described above.

上ハゼ部３２は、矩形板状の本体部３１の外縁部のうち直線状に延在する第１辺部３１ａに沿って設けられている。また、下ハゼ部３３は、矩形板状の本体部３１の外縁部のうち、上ハゼ部３２が設けられている第１辺部３１ａと対向し略平行な直線状の第２辺部（端部屋根材３ａの一辺部３６ａと同じ）に沿って設けられている。 The upper seam portion 32 is provided along a linearly extending first side portion 31 a of the outer edge portion of the rectangular plate-shaped main body portion 31 . In addition, the lower seam portion 33 is a linear second side portion (end portion) facing and substantially parallel to the first side portion 31a on which the upper seam portion 32 is provided, of the outer edge portion of the rectangular plate-shaped main body portion 31 . It is provided along one side portion 36a of the room root member 3a).

本実施形態の端部屋根材３ａ及び中央屋根材３ｂは、上述の上ハゼ部３２及び下ハゼ部３３の延在方向が勾配方向Ａとなるような姿勢で、上述の屋根下地材２に取り付けられる。つまり、本実施形態の金属屋根材３は縦葺き用の屋根材である。 The end roof material 3a and the central roof material 3b of the present embodiment are attached to the roof base material 2 in such a posture that the extending direction of the upper seam 32 and the lower seam 33 becomes the slope direction A. be done. That is, the metal roofing material 3 of this embodiment is a roofing material for vertical roofing.

図２に示すように、上ハゼ部３２は、本体部３１の第１辺部３１ａから立ち上がる第１上ハゼ傾斜側板３２ａと、この第１上ハゼ傾斜側板３２ａの上端に係止顎部３４ａを介してつながり、屋根端部側に隣接して配置される端部屋根材３ａの下ハゼ部３３を内嵌可能な内部空間を区画する上ハゼ頭部３２ｂと、この上ハゼ頭部３２ｂに係止顎部３４ｂを介して垂下し、第１上ハゼ傾斜側板３２ａとの間で下方に向かって幅が拡がる下開き開口を区画する第２上ハゼ傾斜側板３２ｃと、で構成されている。 As shown in FIG. 2, the upper seam portion 32 includes a first upper inclined seam side plate 32a rising from the first side portion 31a of the main body portion 31, and a locking jaw portion 34a at the upper end of the first upper inclined seam side plate 32a. and an upper seam head 32b defining an internal space in which the lower seam 33 of the end roof material 3a arranged adjacent to the roof end side can be fitted. A second upper sloped seam side plate 32c that hangs down via the retaining jaw portion 34b and defines a downward opening that widens downward between the first upper sloped seam side plate 32a and the first upper sloped seam side plate 32a.

上述したように、中央屋根材３ｂの下ハゼ部３３は、端部屋根材３ａの下ハゼ部３３と同様であるため、ここでは説明を省略する。 As described above, the lower seam portion 33 of the central roof member 3b is similar to the lower seam portion 33 of the end roof member 3a, so the description thereof is omitted here.

中央屋根材３ｂの上ハゼ部３２の一方の係止顎部３４ａ及び他方の係止顎部３４ｂは、対向して配置されている。そして、中央屋根材３ｂの上ハゼ部３２において、一方の係止顎部３４ａは、他方の係止顎部３４ｂに向かって突出している。また、中央屋根材３ｂの上ハゼ部３２において、他方の係止顎部３４ｂは、一方の係止顎部３４ａに向かって突出している。つまり、中央屋根材３ｂの上ハゼ部３２には、一方の係止顎部３４ａ及び他方の係止顎部３４ｂにより、括れ部が形成されている。 One locking jaw portion 34a and the other locking jaw portion 34b of the upper seam portion 32 of the central roof member 3b are arranged to face each other. In the upper seam portion 32 of the central roof member 3b, one locking jaw portion 34a protrudes toward the other locking jaw portion 34b. Further, in the upper seam portion 32 of the central roof member 3b, the other locking jaw portion 34b protrudes toward the one locking jaw portion 34a. That is, the upper seam portion 32 of the central roof member 3b is formed with a constricted portion by the locking jaw portion 34a on one side and the locking jaw portion 34b on the other side.

端部屋根材３ａ及び中央屋根材３ｂの下ハゼ部３３の一方の係止顎部３５ａ及び他方の係止顎部３５ｂについても、中央屋根材３ｂの上ハゼ部３２の一方の係止顎部３４ａ及び他方の係止顎部３４ｂと同様の構成を有する。具体的に、端部屋根材３ａ及び中央屋根材３ｂの下ハゼ部３３において、一方の係止顎部３５ａ及び他方の係止顎部３５ｂは、対向して配置されている。そして、端部屋根材３ａ及び中央屋根材３ｂの下ハゼ部３３において、一方の係止顎部３５ａは、他方の係止顎部３５ｂに向かって突出している。また、端部屋根材３ａ及び中央屋根材３ｂの下ハゼ部３３において、他方の係止顎部３５ｂは、一方の係止顎部３５ａに向かって突出している。つまり、端部屋根材３ａ及び中央屋根材３ｂそれぞれの下ハゼ部３３においても、一方の係止顎部３５ａ及び他方の係止顎部３５ｂにより、括れ部が形成されている。 One locking jaw portion 35a and the other locking jaw portion 35b of the lower seam portion 33 of the end roof member 3a and the central roof member 3b also correspond to one locking jaw portion of the upper seam portion 32 of the central roof member 3b. 34a and the other locking jaw 34b. Specifically, in the lower seam portions 33 of the end roof members 3a and the central roof member 3b, one locking jaw portion 35a and the other locking jaw portion 35b are arranged to face each other. In the lower seam portions 33 of the end roof members 3a and the central roof member 3b, one locking jaw portion 35a protrudes toward the other locking jaw portion 35b. Further, in the lower seam portions 33 of the end roof members 3a and the central roof member 3b, the other locking jaw portion 35b protrudes toward the one locking jaw portion 35a. In other words, the lower seam portions 33 of the end roof members 3a and the center roof member 3b are also formed with constrictions by the locking jaws 35a and 35b.

図２に示すように、端部屋根材３ａの下ハゼ部３３は、屋根中央側で隣接する中央屋根材３ｂの上ハゼ部３２に嵌合する。これにより、端部屋根材３ａと中央屋根材３ｂとが連結される。 As shown in FIG. 2, the lower seam 33 of the end roofing material 3a fits into the upper seam 32 of the central roofing material 3b, which is adjacent on the roof center side. Thereby, the end roof material 3a and the center roof material 3b are connected.

また、中央屋根材３ｂは、勾配方向Ａと直交する方向Ｂに直列に複数連結される。その際に、隣接する２つの中央屋根材３ｂは、一方の中央屋根材３ｂの上ハゼ部３２と他方の中央屋根材３ｂの下ハゼ部３３とを嵌合することにより、連結される。 Moreover, the central roof material 3b is connected in series in the direction B orthogonal to the inclination direction A. As shown in FIG. At that time, the two adjacent central roof members 3b are connected by fitting the upper seam 32 of one central roof member 3b and the lower seam 33 of the other central roof member 3b.

このように、上ハゼ部３２及び下ハゼ部３３を嵌合状態にすることで、端部屋根材３ａと中央屋根材３ｂとが連結される。また、上ハゼ部３２及び下ハゼ部３３を嵌合状態にすることで、中央屋根材３ｂ同士が連結される。 By fitting the upper seam portion 32 and the lower seam portion 33 in this manner, the end roof member 3a and the central roof member 3b are connected. Further, by fitting the upper seam portion 32 and the lower seam portion 33, the central roof members 3b are connected to each other.

中央屋根材３ｂの上ハゼ部３２の上ハゼ頭部３２ｂの収容空間に、隣接して配置される端部屋根材３ａ又は別の中央屋根材３ｂの下ハゼ部３３の下ハゼ頭部３３ｂが収容されると、上ハゼ部３２の係止顎部３４ａ、３４ｂと、下ハゼ部３３の係止顎部３５ａ、３５ｂと、が係合することで、引き抜けが抑制される。そのため、本実施形態の上ハゼ部３２及び下ハゼ部３３の嵌合状態は保持され易い。つまり、端部屋根材３ａと中央屋根材３ｂとの連結状態、及び、中央屋根材３ｂ同士の連結状態、が外力等により解除されることを抑制できる。 A lower seam head 33b of an adjacent end roof member 3a or a lower seam portion 33 of another central roof member 3b is placed in the accommodation space of the upper seam head portion 32b of the upper seam portion 32 of the central roof member 3b. When housed, the locking jaws 34a, 34b of the upper seam 32 and the locking jaws 35a, 35b of the lower seam 33 are engaged with each other, thereby suppressing pull-out. Therefore, the fitted state of the upper seam portion 32 and the lower seam portion 33 of the present embodiment can be easily maintained. In other words, it is possible to suppress the disconnection of the connection state between the end roof members 3a and the central roof member 3b and the connection state between the central roof members 3b due to an external force or the like.

なお、本実施形態の金属屋根材３は、上述の端部屋根材３ａ及び中央屋根材３ｂの異なる形状を有する２種類で構成されているが、別の形状の屋根材を含む構成としてもよい。 Although the metal roofing material 3 of the present embodiment is composed of two types having different shapes, that is, the end roofing material 3a and the central roofing material 3b, it may be configured to include roofing materials having different shapes. .

端部金物４は、上述したように、屋根下地材２に支持されている。端部金物４は、金属屋根材３と鉛直方向で部分的に重なるように配置されている。詳細は後述するが、本実施形態の端部金物４は、金属屋根材３のうち端部屋根材３ａと鉛直方向で部分的に重なるように配置されている。本実施形態の端部金物４は、勾配屋根面１０２ｂのケラバ端の雨仕舞のために配置されるケラバ唐草であるが、屋根端部において雨仕舞のために用いられる金物であれば、その構成は特に限定されない。 The end hardware 4 is supported by the roof base material 2 as described above. The end hardware 4 is arranged so as to partially overlap the metal roofing material 3 in the vertical direction. Although the details will be described later, the end hardware 4 of the present embodiment is arranged so as to partially overlap the end roof material 3a of the metal roof material 3 in the vertical direction. The end hardware 4 of this embodiment is a verge arabesque that is arranged for rain protection at the verge edge of the sloped roof surface 102b. is not particularly limited.

端部金物４は、例えば、亜鉛めっき鋼板、アルミニウム亜鉛合金めっき鋼板（ガルバリウム鋼板）、銅板、アルミニウム板、ステンレス鋼板等によって形成することができる。 The end fitting 4 can be formed of, for example, a galvanized steel plate, an aluminum-zinc alloy plated steel plate (Galvalume steel plate), a copper plate, an aluminum plate, a stainless steel plate, or the like.

本実施形態の端部金物４は、屋根下地材２の上面を覆う上面カバー板部４１と、この上面カバー板部４１の端部で連続し、屋根端部で屋根下地材２の側面を覆うように上面カバー板部４１から下方に垂下する側面カバー板部４２と、この側面カバー板部４２の下端から屋根下地材２の下面側に折り返され、上方に向かって延在する折返し板部４３と、備える。 The end hardware 4 of the present embodiment is continuous with the top cover plate portion 41 covering the top surface of the roof base material 2 at the end of the top cover plate portion 41, and covers the side surface of the roof base material 2 at the roof edge. a side cover plate portion 42 hanging downward from the upper surface cover plate portion 41, and a folded plate portion 43 folded back from the lower end of the side cover plate portion 42 to the lower surface side of the roof base material 2 and extending upward. and prepare.

上面カバー板部４１は、金属屋根材３の端部屋根材３ａのうち本体部３６と鉛直方向で重なるように配置されている。つまり、本実施形態の端部金物４は、上面カバー板部４１が本体部３６と鉛直方向で重なるように配置されることで、金属屋根材３と鉛直方向で部分的に重なる。つまり、本実施形態では、金属屋根材３及び端部金物４が鉛直方向に重なって構成される積重部Ｘが、本体部３６及び上面カバー板部４１により形成されている。 The upper surface cover plate portion 41 is arranged so as to vertically overlap the main body portion 36 of the end roof member 3 a of the metal roof member 3 . That is, the end metal fitting 4 of the present embodiment partially overlaps the metal roofing material 3 in the vertical direction by arranging the upper surface cover plate portion 41 to overlap the main body portion 36 in the vertical direction. That is, in the present embodiment, the main body portion 36 and the upper surface cover plate portion 41 form the stacked portion X in which the metal roofing material 3 and the end metal fittings 4 are stacked vertically.

図２に示すように、本実施形態の上面カバー板部４１は、上述の積重部Ｘよりも屋根中央側の、端部屋根材３ａの本体部３６に覆われる位置で、ビス等の締結部材６により屋根下地材２に締結されている。また、上面カバー板部４１は、屋根中央側の端部に上方に折り返された折返し端部４１ａを備える。 As shown in FIG. 2, the upper surface cover plate portion 41 of the present embodiment is located on the center side of the roof with respect to the above-described stacked portion X and is covered with the body portion 36 of the end roof material 3a. It is fastened to the roof substrate material 2 by the member 6 . Further, the upper surface cover plate portion 41 has a folded end portion 41a folded upward at the end portion on the center side of the roof.

本実施形態において、金属屋根材３は、積重部Ｘにおいて、端部金物４の上方に重なっている。つまり、金属屋根材３の本体部３６が、端部金物４の上面カバー板部４１の上方に重なっている。しかしながら、積重部Ｘにおける金属屋根材３及び端部金物４の上下の位置関係は特に限定されず、後述するように、端部金物４が、積重部Ｘにおいて、金属屋根材３の上方に重なる構成であってもよい（図４参照）。 In the present embodiment, the metal roof material 3 overlaps the end metal fittings 4 at the stacked portion X. As shown in FIG. That is, the body portion 36 of the metal roofing material 3 overlaps above the upper surface cover plate portion 41 of the end hardware 4 .

The first water stop member 5 is sandwiched between the metal roofing material 3 and the end hardware 4 by a fastening member 6 which will be described later. By arranging the first water stop member 5 in this way, it is possible to suppress water such as rainwater from entering the roof portion 102 from between the metal roof material 3 and the end metal fittings 4 in the stacked portion X. .

更に、このような第１止水部材５を配置する構成を採用することで、金属屋根材３及び端部金物４の施工性を高めることができる。つまり、金属屋根材３及び端部金物４の位置関係を、積重部Ｘの重なり度合いにより、施工時において簡単に調整できる。そのため、積重部Ｘの重なり度合いにより、金属屋根材３の寸法の個体差等により生じる寸法誤差を容易に吸収できる。これにより、端部金物４の雨仕舞のための部位（本実施形態では側面カバー板部４２及び折返し板部４３）を施工現場で加工（本実施形態では折り曲げ加工）しなくよい。 Furthermore, by adopting such a configuration in which the first water stop member 5 is arranged, the workability of the metal roofing material 3 and the end metal fittings 4 can be enhanced. In other words, the positional relationship between the metal roof material 3 and the end metal fittings 4 can be easily adjusted according to the overlapping degree of the stacked portion X during construction. Therefore, depending on the degree of overlapping of the stacked portions X, dimensional errors caused by individual differences in the dimensions of the metal roofing materials 3 can be easily absorbed. As a result, it is not necessary to process (bend in this embodiment) the portions of the end hardware 4 for rain protection (the side cover plate portion 42 and the folding plate portion 43 in this embodiment) at the construction site.

第１止水部材５は、弾性変形可能な材料により形成されていることが好ましい。第１止水部材５としては、例えば、ブチルテープやエチレン・プロピレン・ジエンゴム等を使用することができるが、特に限定されず、例えば、ブチル系、シリコーン系、アクリル系のゴムやシーリング材としてもよい。 The first waterproof member 5 is preferably made of an elastically deformable material.

締結部材６は、積重部Ｘの位置で、金属屋根材３及び端部金物４を貫いて屋根下地材２に締結されている。第１止水部材５は、この締結部材６により、金属屋根材３と端部金物４との間で挟み込まれている。このようにすることで、上述したように、積重部Ｘにおいて、金属屋根材３と端部金物４との間から雨水等の水が屋根部１０２内に侵入することを抑制できる。 The fastening member 6 is fastened to the roof base material 2 at the position of the stacked portion X through the metal roof material 3 and the end hardware 4 . The first water stop member 5 is sandwiched between the metal roofing material 3 and the end hardware 4 by the fastening member 6 . By doing so, as described above, it is possible to prevent water such as rainwater from entering the roof portion 102 from between the metal roof material 3 and the end hardware 4 in the stacked portion X.

より具体的に、本実施形態の第１止水部材５は、締結部材６の作用により、金属屋根材３と端部金物４の間で圧縮された状態で挟み込まれている。特に、本実施形態の締結部材６は、積重部Ｘの位置で、金属屋根材３及び端部金物４に加えて、第１止水部材５をも貫いた状態で、屋根下地材２に締結されている。このようにすることで、第１止水部材５がより強固に挟み込まれ、第１止水部材５によるシール性能を高めることができる。 More specifically, the first water stop member 5 of the present embodiment is sandwiched between the metal roof material 3 and the end metal fitting 4 in a compressed state by the action of the fastening member 6 . In particular, the fastening member 6 of this embodiment is attached to the roof base material 2 in a state in which it penetrates not only the metal roof material 3 and the end metal fittings 4 but also the first water stop member 5 at the position of the stacked portion X. has been concluded. By doing so, the first water-stopping member 5 is sandwiched more firmly, and the sealing performance of the first water-stopping member 5 can be enhanced.

更に、本実施形態の締結部材６は、積重部Ｘの位置で、後述の押さえ部材７及び第２止水部材８を貫いて、屋根下地材２に締結されている。つまり、本実施形態の締結部材６は、上述の金属屋根材３、端部金物４及び第１止水部材５に加えて、押さえ部材７及び第２止水部材８をも貫いた状態で、屋根下地材２に締結されている。このようにすることで、勾配屋根面１０２ｂ（図１参照）を構成する金属屋根材３の上面を流れる雨水等の水が、締結部材６が挿通する締結孔を通じて屋根部１０２内に侵入することを抑制できる。この詳細は後述する。 Furthermore, the fastening member 6 of the present embodiment is fastened to the roof base material 2 at the position of the stacked portion X through the pressing member 7 and the second water stop member 8 which will be described later. In other words, the fastening member 6 of this embodiment passes through the pressing member 7 and the second water stop member 8 in addition to the metal roof material 3, the end hardware 4, and the first water stop member 5 described above. It is fastened to the roof base material 2 . By doing so, water such as rainwater flowing on the upper surface of the metal roof material 3 forming the sloped roof surface 102b (see FIG. 1) is prevented from entering the roof portion 102 through the fastening holes through which the fastening members 6 are inserted. can be suppressed. Details of this will be described later.

また更に、本実施形態では、締結部材６が、積重部Ｘの位置で、後述の防水シート部材９をも貫いて、屋根下地材２に締結されている。 Furthermore, in the present embodiment, the fastening member 6 is fastened to the roof base material 2 at the position of the stacked portion X, also penetrating the waterproof sheet member 9 described later.

本実施形態の締結部材６は、外面にねじ山が形成されている棒状の雄ねじ部６１と、この雄ねじ部６１から径方向外側に突設されているフランジ部６２と、を備える。より具体的に、本実施形態の締結部材６は金属製のビスであり、本実施形態のフランジ部６２はビス頭部により構成されている。したがって、本実施形態の金属屋根材３、端部金物４、第１止水部材５、押さえ部材７、第２止水部材８及び防水シート部材９は、締結部材６のフランジ部６２としてのビス頭部と、屋根下地材２と、の間に挟み込まれている。 The fastening member 6 of the present embodiment includes a rod-shaped externally threaded portion 61 having threads formed on its outer surface, and a flange portion 62 projecting radially outwardly from the externally threaded portion 61 . More specifically, the fastening member 6 of the present embodiment is a metal screw, and the flange portion 62 of the present embodiment is composed of a screw head. Therefore, the metal roofing material 3, the end metal fittings 4, the first water stop member 5, the pressing member 7, the second water stop member 8, and the waterproof sheet member 9 of this embodiment are provided with screws as the flange portion 62 of the fastening member 6. It is sandwiched between the head and the roof base material 2. - 特許庁

押さえ部材７は、積重部Ｘの上方に配置される。押さえ部材７は、耐水性能及び防錆性能の高い構成とされる。押さえ部材７は、例えば樹脂を主成分とする構成にすることができる。積重部Ｘと押さえ部材７との間に後述する第２止水部材８を介在させた状態で、上述の締結部材６を、押さえ部材７の上面から屋根下地材２に至るまで挿入し締結することにより、第２止水部材８を、積重部Ｘと押さえ部材７との間に挟み込ませることができる。このような押さえ部材７を設けることで、勾配屋根面１０２ｂ（図１参照）を構成する金属屋根材３の上面を流れる雨水等の水は、押さえ部材７の側面に接触するが、押さえ部材７の上面には接触し難くなる。つまり、このような押さえ部材７を設け、この押さえ部材７の上面から締結部材６を挿入する。このようにすれば、金属屋根材３の上面を流れる雨水等が、押さえ部材７の上面から外部に露出する締結部材６の上面に接触し難い。そのため、本実施形態のように締結部材６を金属製のビスとしても、締結部材６が錆びることを抑制できる。更に、金属屋根材３の上面を流れる雨水等の水が締結部材６の締結孔に入り難くなる。そのため、締結孔から屋根部１０２内に水が侵入することをも抑制できる。また更に、第２止水部材８を設けることで、締結孔から屋根部１０２内に水が侵入することを、より抑制できる。この詳細は後述する。 The pressing member 7 is arranged above the stacked portion X. As shown in FIG. The pressing member 7 is configured to have high water resistance and rust prevention performance. The pressing member 7 can be made mainly of resin, for example. With a second water stop member 8 to be described later interposed between the stacked portion X and the holding member 7, the fastening member 6 described above is inserted from the upper surface of the holding member 7 to the roof base material 2 and fastened. By doing so, the second water stop member 8 can be sandwiched between the stacked portion X and the pressing member 7 . By providing such a pressing member 7, water such as rainwater flowing on the upper surface of the metal roof material 3 constituting the sloped roof surface 102b (see FIG. 1) contacts the side surface of the pressing member 7, but the pressing member 7 It becomes difficult to touch the upper surface of the That is, such a pressing member 7 is provided, and the fastening member 6 is inserted from the upper surface of this pressing member 7 . In this way, rainwater or the like flowing on the upper surface of the metal roofing material 3 is less likely to come into contact with the upper surface of the fastening member 6 exposed to the outside from the upper surface of the pressing member 7 . Therefore, even if the fastening members 6 are metal screws as in the present embodiment, the fastening members 6 can be prevented from rusting. Furthermore, it becomes difficult for water such as rainwater flowing on the upper surface of the metal roofing material 3 to enter the fastening hole of the fastening member 6 . Therefore, it is possible to prevent water from entering the roof portion 102 through the fastening holes. Furthermore, by providing the second water stop member 8, it is possible to further suppress water from entering the roof portion 102 through the fastening holes. Details of this will be described later.

１つの押さえ部材７には、複数の締結部材６が挿通されている。換言すれば、押さえ部材７は、締結部材６が締結される複数の位置に跨るように配置されている。そのため、複数の締結部材６の間の位置においても、押さえ部材７と屋根下地材２との間で、上述の金属屋根材３、端部金物４、第１止水部材５、第２止水部材８及び防水シート部材９を挟み込むことができる。すなわち、このような押さえ部材７とすることで、締結部材６が設けられていない位置でのシール性を高めることができる。 A plurality of fastening members 6 are inserted through one pressing member 7 . In other words, the pressing member 7 is arranged across a plurality of positions where the fastening member 6 is fastened. Therefore, even at positions between the plurality of fastening members 6, the above-described metal roof member 3, end hardware 4, first water stop member 5, and second water stop member 5 are provided between the pressing member 7 and the roof base material 2. The member 8 and the waterproof sheet member 9 can be sandwiched.

押さえ部材７は、特に限定されないが、耐水性能及び防錆性能の高い構成とされることが好ましい。一例として、本実施形態の押さえ部材７のように、樹脂を主成分とする構成とすることができる。なお、樹脂を主成分とする構成とは、樹脂の重量パーセントが５０％以上の構成を意味する。したがって、押さえ部材７は、樹脂のみから構成（樹脂の重量パーセント１００％）されてもよく、樹脂に木粉が混ぜ合わされた構成としてもよい。更に、押さえ部材７は、外表面のみを樹脂で被覆された構成であってもよい。樹脂の材料としては、例えば、ポリエチレン、ポリプロピレン、ＡＢＳ樹脂、ポリスチレン等が挙げられる。また更に、押さえ部材７は、防錆処理されたステンレス等の金属から構成されてもよい。このように、押さえ部材７は、耐水性能及び防錆性能の高い構成であれば、その形成材料は特に限定されない。したがって、押さえ部材７は、例えば、上述のような各種材料から形成される耐水性能及び防錆性能の高い、断面矩形状の角棒部材とすることができる。 Although the pressing member 7 is not particularly limited, it preferably has a structure with high water resistance and rust prevention performance. As an example, like the pressing member 7 of the present embodiment, it can be configured to have a resin as a main component. In addition, the structure which has resin as a main component means the structure whose weight percentage of resin is 50% or more. Therefore, the pressing member 7 may be composed only of resin (100% by weight of resin), or may be composed of resin mixed with wood flour. Furthermore, the pressing member 7 may be configured such that only the outer surface thereof is coated with resin. Examples of resin materials include polyethylene, polypropylene, ABS resin, and polystyrene. Furthermore, the pressing member 7 may be made of a metal such as stainless steel that has undergone an antirust treatment. As described above, the pressing member 7 is not particularly limited in material as long as it has a structure with high water resistance and rust prevention performance. Therefore, the pressing member 7 can be, for example, a square bar member having a rectangular cross section and having high water resistance and rust prevention performance, which is made of various materials as described above.

第２止水部材８は、積重部Ｘと押さえ部材７との間に位置する。上述したように、締結部材６は、積重部Ｘの位置で、上述の金属屋根材３、端部金物４、第１止水部材５、押さえ部材７、第２止水部材８及び防水シート部材９を貫いた状態で、屋根下地材２に締結されている。そのため、第２止水部材８は、この締結部材６により、積重部Ｘと押さえ部材７との間で挟み込まれている。第２止水部材８は、積重部Ｘと押さえ部材７との間で圧縮され、積重部Ｘと押さえ部材７との間のみならず、締結孔の位置で締結部材６の周囲にも密着した状態となる。このような第２止水部材８を設けることで、仮に締結部材６の締結孔から雨水等が侵入したとしても、第２止水部材８が締結部材６と密着しているため、水がそれ以上侵入することを抑制できる。つまり、締結孔から屋根部１０２内に水が侵入することを、より抑制できる。 The second water stop member 8 is positioned between the stacked portion X and the pressing member 7 . As described above, the fastening member 6, at the position of the stacked portion X, the metal roof material 3, the end hardware 4, the first water stop member 5, the pressing member 7, the second water stop member 8 and the waterproof sheet It is fastened to the roof base material 2 while penetrating the member 9. - 特許庁Therefore, the second water stop member 8 is sandwiched between the stacking portion X and the pressing member 7 by the fastening member 6 . The second water stop member 8 is compressed between the stacking portion X and the pressing member 7, and not only between the stacking portion X and the pressing member 7, but also around the fastening member 6 at the position of the fastening hole. It becomes a state of close contact. By providing such a second water stop member 8, even if rainwater or the like enters through the fastening hole of the fastening member 6, the second water stop member 8 is in close contact with the fastening member 6, so that the water can be prevented from entering. Intrusion can be suppressed. That is, it is possible to further prevent water from entering the roof portion 102 through the fastening holes.

第２止水部材８は、第１止水部材５と同様、弾性変形可能な材料により形成されていることが好ましい。第２止水部材８としては、例えば、ブチルテープやエチレン・プロピレン・ジエンゴム等を使用することができるが、特に限定されず、例えば、ブチル系、シリコーン系、アクリル系のゴムやシーリング材としてもよい。なお、第１止水部材５と第２止水部材８とを同一の材料から構成してもよく、別の材料から構成してもよい。 Like the first water stop member 5, the second water stop member 8 is preferably made of an elastically deformable material. As the second waterproof member 8, for example, butyl tape, ethylene/propylene/diene rubber, etc. can be used, but there is no particular limitation. good. The first water stop member 5 and the second water stop member 8 may be made of the same material, or may be made of different materials.

防水シート部材９は、屋根下地材２と金属屋根材３との間、及び、屋根下地材２と端部金物４との間、に介在させることができる。より具体的に、本実施形態の防水シート部材９は、屋根下地材２上に敷設されている。上述した金属屋根材３、端部金物４、第１止水部材５、締結部材６、押さえ部材７及び第２止水部材８は、防水シート部材９上に配置される。 The waterproof sheet member 9 can be interposed between the roof base material 2 and the metal roof material 3 and between the roof base material 2 and the end metal fittings 4 .

防水シート部材９は、防水性能を有する材料から構成されていればよく、例えば、アスファルトルーフィングを用いることができる。 The waterproof sheet member 9 may be made of a material having waterproof performance, and for example, asphalt roofing can be used.

カバー部材１０は、押さえ部材７の上方を覆うように配置される。このようなカバー部材１０を設けることで、雨水が締結部材６の上面に降り注ぐことを抑制できる。そのため、本実施形態のように締結部材６を金属製としても、押さえ部材７の上面から露出する締結部材６が錆びることを抑制できる。また、締結部材６の締結孔から雨水が入ることについても抑制できる。更に、樹脂を含む押さえ部材７は、太陽光により劣化するおそれがあるが、カバー部材１０を設けることで、押さえ部材７の太陽光による劣化を抑制できる。 The cover member 10 is arranged so as to cover the pressing member 7 from above. By providing such a cover member 10 , it is possible to prevent rainwater from falling on the upper surface of the fastening member 6 . Therefore, even if the fastening member 6 is made of metal as in the present embodiment, it is possible to prevent the fastening member 6 exposed from the upper surface of the pressing member 7 from rusting. In addition, it is possible to prevent rainwater from entering through the fastening hole of the fastening member 6 . Furthermore, although the pressing member 7 containing resin may be deteriorated by sunlight, the provision of the cover member 10 can suppress deterioration of the pressing member 7 due to sunlight.

より具体的に、本実施形態のカバー部材１０は、押さえ部材７の上方を覆う本体部１０ａと、この本体部１０ａの屋根中央側の端部から垂下し、押さえ部材７の側面の少なくとも一部を覆う第１側部１０ｂと、本体部１０ａの屋根中央側とは反対側の端部から垂下し、押さえ部材７の側面全域及び屋根下地材２の側面の少なくとも一部を覆う第２側部１０ｃと、を備える。また、本実施形態のカバー部材１０は、締結部材６により押さえ部材７の上面に固定された支持部材１１により支持されているが、支持部材１１がなく、押さえ部材７に直接取り付けられるカバー部材としてもよい。 More specifically, the cover member 10 of this embodiment includes a body portion 10a that covers the upper side of the pressing member 7, and a portion of the side surface of the pressing member 7 that hangs down from the end portion of the body portion 10a on the center side of the roof. and a second side portion that hangs down from the end of the main body portion 10a on the side opposite to the center side of the roof and covers the entire side surface of the pressing member 7 and at least part of the side surface of the roof base material 2 10c.
